specification 1, the title of the invention
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the improvement
of a connector for an underwater heater, and more specifically, both mechanical coupling and
electrical coupling can be easily performed in row-1 coupling and detachment. Applications for
such devices with regard to construction are found in underwater acoustics fx. The acoustic
device uses a piezoelectric element that acts as a transducer to convert electricity to sound and
sound to electricity. Pressure IE element '! When it is excited, its physical dimensions change
slightly. This dimensional change is so fast that the water in contact with the 0-vove expands and
contracts to generate a sound IIi, ie an acoustic signal. The pressure 1 can also act as a receiver,
propagate water, and enter the piezoelectric element The acoustic energy changes the size,
resulting in an electrical signal. In the case where the piezoelectric element is used as a
transmitter of an acoustic signal, the piezoelectric element is excited by a signal generator, and
when used as a hydrophone for receiving the piezoelectric element 1f 41, this company The
receiver or processor of the electrical signal is combined. King transmitter and receiver! It is
usually desirable to keep the element in close proximity, in which case the KrI'i electronic
processor and the voltaic element must be submerged in water. However, when the piezoelectric
element is completely surrounded by water, the transmitter and the receiver are housed in
separate cases, as a satisfactory coupling of the piezoelectric element and water is most easily
achieved. The electronic processor is contained within a sealed container, and thus is the base or
frame of the container assembly. This assembly is strong and heavy compared to the structure of
piezoelectrics that the design of the piezoelectric element determines because the impedance of
the piezoelectric element t needs to be matched to the impedance of the water in which it is
immersed, in fact Kti the final overall The structure is a structure in which a piezoelectric element
is attached as an accessory to a container for containing an electronic device. The piezoelectric
element is mechanically held at a fixed position from the piezoelectric element tPk from the
mounted f'L, 6 at a certain distance from the container, and for transmitting an electrical signal
in the dark of the piezoelectric element and the electronic device Which structure to use for? I
need. One practical example is to connect the π echo transmitter and receiver to both ends of
the cable. This device can be mounted on a helicopter and can be mounted on a flooded vessel or
platform, which allows the transmitter and receiver to transmit and receive sound for various
purposes. I can sink it in the water. The purposes include submarine detection, submarine
communication, underwater pipeline valve location and operation, fish detection, sound
navigation, etc.
Some pressure 'flt leafs' can be made to be able to sense the device by attaching it to the
container so that the pressure% elements extend radially from the container. Several pressure IE
accumulators 1c are connected to the receiver in an order to determine the direction of the
distant sound W signal source "j". The amplitude of the bias reaching those piezoelectric
elements is compared to identify the element that receives the strongest signal, and in the case of
a two-to-one operation, the piezoelectric elements are separated by two pairs of receiving
elements. Connect to the machine and compare the received signal strength t. From the result of
this comparison, the direction EndPage: 2 of the signal source is estimated. In one practical
example, #i is about 30.5a + (one foot) in diameter and about seven inches in length (within a 2,5
foot 1 central container). This volume is enclosed by a coaxial cable route separated by a selected
distance from 1-. The piezoelectric element is attached to the shield. The piezoelectric element is
long-bar-like. These piezoelectric elements are mounted outward from the shield in a radial plane
including the axis of the unisheet. Twelve pieces are used as 24 rod-like piezoelectric elements.
Each piezoelectric element is attached to the shield apart from the shield so as to be completely
surrounded by water, except for the arm parts for connector connection. The spacing between
the piezoelectric element and the shield and the threshold spacing between the shield and the
container are selected to provide the desired acoustic effect. In one example of such installation,
the rod-like piezoelectric accumulator is about from the shield! Mounted 5aw (one inch) apart.
Shield #i diameter electronic equipment containers of about 3 (Loam (one foot)) are also
mounted approximately 5 to 7.5 am (about 2 to 3 inches) apart. OOz knit 嬬 shield and rod-like
piezoelectric element 【@ when connected to each other, 4 、 0 bracket 4 included for
electrically connecting the electronic device in the center container and the rod-like piezoelectric
element It is important to provide an interconnection structure in which the rod-like piezoelectric
element is irritated when the rod-like piezoelectric element is drawn from the submerged L water
and is fc. Becomes complicated due to the fact that it may cause a malfunction. Because
helicopters are always constantly cleaned when moving unilet in and out of water, rod-like
piezoelectric electrons may break and they may not operate at the desired frequency for 71
operation, so such piezoelectric elements An interconnecting member that can be easily replaced.
Easy to replace rod-shaped piezoelectric element can not be mining without butterfly pair.
What is required is a rod-shaped piezoelectric element, an electronic device container, and a
connector of 0 number type, which are easy to be attached and detached, and have a water-proof
type so that seawater which is both conductive and corrosive t-infiltrates. Mechanical linkage is
also required. This mechanical interlocking Fi-layer removal should be easy, and it should be able
to maintain the proper distance between the interlockings and provide the required strength and
rigidity: Conclusion One mechanical It would be desirable and desirable to have a plug-in
connection that allows simultaneous coupling and electrical coupling. However, plug-in
constructions that can withstand high water pressure without leakage, other easily removable
connection members have proved difficult to realize. This kind of underwater sound II
component is an interconnecting member which has been placed in a rod-shaped piezoelectric
element and extended to a container in which the electronic device is housed at a break for many
years, where it is fixed to the container by a fixing member In this structure, one member that
couples the piezoelectric element to the electronic device is different from the one that easily
bonds to the electronic device. You need to open the container. Therefore, the replacement work
of the piezoelectric element needs to be sent to the manufacturing plant of the device if it is 9 °
when it is a difficult job. The purpose of the failure + 411 overcomes the above-mentioned
difficulties and the rod-like piezoelectric element 5e of rod-like piezoelectric elements without
being tested on the field exchange 1 ir function and how percolating it does not carry out 5e of
the rod-like piezoelectric element is reliable enough to be used immediately after connection It is
by doing. The invention is to provide a structure t-which meets this purpose. Since this structure
is extremely robust and extremely reliable that anyone can handle, it is necessary to replace the
piezoelectric element without using special equipment and without requiring special skills. Can.
The embodiment shown in the drawings shoulders other advantages. This structure is combined
with the structure of the baffle in such a way as to protect the connector assembly from
vibrations at the joints 11. The baffle is made of a sheet of plastic which is mostly plastic.
However, the upper end and lower end & 1 of this baffle are made of 7 run 2 heavy. The
connector assembly extends through the lower flange and the parts used to connect the parts of
the assembly (coupling) are also used to attach to the assembly upper flange. EndPage: 3 is held
firmly against the outer rims of the upper 7 and lower flanges of the baffle. Because the flanges
of ours extend outward of the main body of the baffle.
The middle portion of each rod-like piezoelectric element is separated from the baffle. The plug-
in connector -S is fixed to the rod-like piezoelectric element, and the other part is fixed to the
central container. This other part of the connector comprises an element for insertion into -11
fixed to the piezoelectric element, this group comprising a stem extending in the container 1
from the interconnection structure. Thus, the points at which the interconnection elements are
provided are some distance away from the container. Coupling members are used to secure them
to each other. This cup link is fitted into a hole in the baffled flange km. Bonding parts that are
also designed to perform pattern bonding are aligned so that one is held by the rod-shaped
pressure element and the other is held by the container. Configured In order for the electrical
interconnection members contained in the circle lIi of the cup-shaped coupling element to be
securely coupled without failure and for the sealing member to function effectively, the coupling
members need to be properly aligned. The member is configured such that one wall slides in the
other central hole. The two members are provided with surfaces that are superimposed upon
each other when joined. The fact that one coupling member is mounted on top of a resilient soft
sealing element "<b on another coupling member must be able to reliably predict the relative
position of all parts when assembled. Become. A stack of airspaces is formed in the two
connecting members and the cavity has a special cross-sectional self-shape for accommodating
an annular sealing member. The stop member is assembled and EEE crimped in the fC body to
seal. Nevertheless, one coupling member is at the bottom with respect to the other coupling
member. In such an arrangement there are 2-2 coupling members / Ii precisely connected to it,
with which the machining position adjustment is retained and also sealing. The present invention
I @ t-detail K11S! As FIG. 1 shows, the housing 44-fiA is viewed, since it is about half of the baffle
60 removed so that the side l11r11 can be seen. Since the entire unit is suspended by the cable
11, the central axis is vertical. ! 1! 2 is the left side part t in Fig.1. The piezoelectric element is
housed in a thin case to form an assembly 910 "totally called a" stab ". The stave has a width of
about 2.5 am (about 1 inch), a thickness of 9 mm (about 378 inches), and a length of about 1.5
to 1.8 feet (about several feet). Inside the lower side of the stave, the mineral piezoelectric
element and its casing are mounted on the Ill di bracket 12, and the bracket surrounds the rear
of the stave.
Brackets) 12IIi Force-made-in-one with the bottom surface of the tacking member 1 @ or joined
to the bottom surface as shown. The member 16 is generally circular-cylindrical. The S-material
16 has a thick-buttock wall, and its I11 has a uniform thickness except at the front end. The front
end S is formed into a conical front portion 111 which is cut off and is partially oriented towards
the stave end mtic. In the cross-sectional view, the front part is shown by a slant line which turns
around the front end and draws an arc with a large diameter. A screw thread 20 is provided on
the mantle of the outer S wall on the heel portion. -The other coupling member 22 comprises a
cup-shaped portion 24t and has a part line bottom wall 26 '. The bottom wall is provided with a
hole penetrating in the axial direction, and the tube or stem 2B is pressed into the hole. Stem 28
is considered to be part of coupling member 22. The outer diameter of the front s3G of the cupshaped portion 24 is smaller. The front WA is such a diameter as to slide into the front end of the
member 10). A shoulder 34 is formed at the junction of the front portion 30 and the rear portion
1132 where the outer diameter of the rear daughter portion of the cup-shaped member 24 is
approximately equal to the outer diameter of the front end of the coupling member 164E) The
leading edge of member 16 contacts wedge 36. These two fronts are shown as being
perpendicular to the axis of the connector. This configuration is preferred, although a
configuration of the sacrum is also possible. Importantly, the two shoulders can be made to be
dimmer to fix the position of one shoulder relative to the other by allowing one shoulder to rest
on the other's debris. is there. The electrical connections are contained in the actual holes of the
two coupling members. It takes place between the coupling parts of the connector. EndPage: 4 It
is extremely important to keep water out of the hole. The seal needs to be sealed, and in the
embodiment described here IC1 an annular seal 'ring 4- plays its role, this ring being the conical
surface 1B of the coupling member 1 @ and the coupling member 22 It is inserted into the
annular space which appears between it and the outer wall. An annulus 42 is formed in the lower
11 portion of the wedge slope 118 on the coupling member 22. The cross-sectional shape of this
groove is wedge-shaped, and the assembly of the front KO ring sealing member 4 ··· which has its
narrow width directed towards the stave 10 is a cup-shaped connecting member 24t- A sealing
member 4g is placed at the bottom of the Wcs material 24 so as to be inside. Since the sealing
member 4 is pressed in the narrow direction of the width of the groove 42 when the connecting
part is assembled, it is held compressed in the groove 40 of the member 40, and the connecting
member in which water is intruding is a stave The outer diameter of the outer end is reduced so
that it can slide into the coupling member secured to the.
However, although less desirable for practical reasons, the configuration can be reversed so that
the side walls of the cup-shaped member 16 are formed like the side walls of the cup-shaped
member 24. Similarly, the plug portion and the receptacle portion of the electrical connector can
be replaced with each other to determine whether or not the structure of the mechanical
coupling member is reversed. The figure shows a preferred structure. In the figure, the male part
of the electrical connector is held by the connecting member 16 and the stave IOK. The structure
of the coupling member of the mechanical connector is such that the entire length of the front
portion of the cup-shaped member 24.0 is inserted into the front wall of the coupling portion
i16, and the surfaces 34 and 36 having the complementary relationship KTo II Because of this,
extremely high rigidity can be obtained. The relative position f intended by the designer is
determined regardless of whether or not the% 2 coupling member is properly fitted at the
beginning of the plug-in procedure by this and the member forming the four-part to be inserted
into the sealing member 4o-fi. Two coupling members and a sealing member can occupy. The
mechanical connector design is integrated with the baffle 60 design. Over the entire length of the
stub, the connector is attached to the stub at the heel of the stub which does not need to be
spaced apart as it is necessary to move the stave a selected distance from the baffle. At this end
portion / (the width of the rubble is very wide, it forms a protective bumper ring 62'Z. The
bumper ring extends below the plane of the electronic housing and provides for securing both
the strap and the housing, the ring being provided with a series of holes. These holes are in a
common horizontal plane 〇, ラ, on the rhine. The axes of these holes extend from the vertical
axis of the electronic unit. One of these holes is visible in FIG. The inner wall of this hole is shown
at 64. The width of the damper ring 62, and hence the depth of the holes, is more than half the
combined length of the coupling members 16 and 26. The connector extends through the hole,
the outer diameter of the connector assembly just enters the hole), and the baffle from K is
configured to provide rigidity to the mechanical connector. In this embodiment the coupling
members 16 and 26 are fixed to each other by means of barrel nuts 66]. The Natto as a whole is
cylindrical, but its inner end is a hexagonal collar 68 whose outer diameter is shorter than the
outer diameter of the cylindrical portion. The inner diameter of the collar is slightly larger than
the outer diameter of the tube 28. The inner diameter of the left end portion of the barrel nut 66
is large. The nut 66 can be inserted and assembled from the outside of the connecting members
16 and 26.
The inner wall of the left end portion of the nut 66 is provided with a screw groove, and the
screw groove is screwed into the screw thread 21) K of the coupling member 16. The entire
length of the nut 66 can be withdrawn so that the nut can be removed from the threaded portion
20 and then its barrel can be fully slid over the coupling member so that the collar 68 can be
pulled back over the tube 2. It is large enough to be moved. The nut 66t can be sufficiently
retracted so that the barrel nut 66 completely separates from the connecting member 16.26. The
outer surface of the left end of the barrel nut 66 is smooth. The outer diameter of this nut is sized
to fit within the bumper ring 626 size. In this embodiment, the baffle and its bumper ring are
made of a relatively soft material. For that reason the eyelet is inserted into the hole from both
sides. Each tome has a cylindrical portion inserted into the hole of the bumper ring and a flange
portion which goes out of the hole. The stave-side flange 70 is permanently fixed to the stave.
The outer diameter of the barrel nut is sized to slide into these two eyelets. The front outer edge
of the barrel nut is slightly chamfered so that the barrel nut can be easily inserted into the
hatnoa 2. This chamfered portion is indicated by numeral 14. The connecting member 16 # i is
fixed to the stave 1o. The coupling member 26 is clamped in engagement with the coupling
member 16. The assembly is completed with a screw IIK screwed jam nut 74iK at the right end of
the barrel nut 66. The jam nut 76 # i is tightened against the washer 80 placed on the eyelet 72.
Tightening the Natto 74i will force the Baffle Rin @ / @ 2 # 'i ^ Tome TDIIC, making the whole
assembly very robust. Mechanical connectors and their internal electrical connections are
blocked from making electrical connections such as neta and electrical connections, and other
types of relative movement such as sealing. In this connection, it can be seen that in FIG. 2 the
lower part of the ball-full ring 62 is in contact, but away from the upper part. In fact, the upper
part of the toe is slightly fanned to round the assembly JIK, but most of the baffle ring and one
tome ilI range and F! Keep in touch. At the other end of the tube 28 two sets of threads are
provided. One threaded portion is formed at the end where the channel 28 enters the inside of
the housing. The other thread is provided in the part which goes out of the one of the gings.
The housing O wall is provided with a hole 9 ° for receiving the tube 28. This hole is larger in
diameter in the part s2 to receive the parachute presser 94 compressed by the compression
member s6. A screw groove is provided at the upper end of the hole 9o, and a pressure aim
material s6 is screwed into this groove. When the tube 28 is inserted into the hole so and then
the compression member is tightened, the backing holder S4 seals so that seawater does not
enter the housing. The tube 28 is held by the jam nut 100 at a predetermined position in the
assembly. The nut 100 is clamped inside the housing against the end of the compression part '$
6. The tube 28 is also tightened by means of a nut 102 which is screwed onto the tube thread
outside the clamp. The electrical connector comprises a jack and a plug 8 In this embodiment the
jack is a commercially available 2-conductor female jack. Plug, also standard commercial. されて
いるものである。 The plug is shown in FIG. The base 46 of the prong is insulated from the stem
48 of the plug by an internal insulating sleeve. The plug is assembled in such a way that the base
46 is sealed by means of a soft / spindle in an iron sleeve 52 which forms part of the weld of the
staple material. The sleeve 52 is silver brazed into the axial bore of the coupling member 16.
Such a structure prevents the infiltration of seawater. An in-recess KO ring seal 56 formed on the
inner wall of the member 16 is distributed between the member 16 and the bushing 52. The
dimensions of the OI J-ring 56 and the dimensions of the recess are such that the O-ring pushes
strongly against both the member 16 and the bushing 520 so that seawater does not leak
through the ring. Despite the limited elasticity in the bushing 52, the plug is too hard for the
normal operation of the jack 82. The jack has a cylindrical metal body 84. The metal body has a
metal wall at its entire input end in which a threaded nipple 86 is screwed and has an axial bore
for receiving the plug. Inside the body 84 the end of the plug is engaged by a resiliently mounted
contact 88. The bias of the contacts is not symmetrical. In normal 'operation, the piacek exerts a
force to tilt the plug, forcing its axis against the nipple and the side wall of the end wall. In this
case, however, the plug is so robust that it can be tilted because the jack is gimbaled on the side.
ジャックはJ! It has a cylindrical EndPage: 6 extension cover 8s. Since this cover is very loosely
inserted inside the coupling member 24, it can be inclined by yp4. However, the adjustment of
the depth is maintained by the spacer 87 screwed into the nipple 86. The rear peripheral surface
of the spacer 81 is KO-KOned on the shoulder formed on the inner wall of the front 113θ of the
coupling member 24. Similar to the cover 89, the spacer 8T can be inclined from 4 thinner than
the inner diameter of the hole into which it is inserted. The entire assembly is held in place by
enclosing several segments of the front end of the front 3o, as shown at 83 in FIG. The great
advantage of this plug and jack configuration is that it is symmetrical about its central axis as
well as the mechanical connector. There is no need to rotate and orient the plug and jack in
particular. Mounting the jack portion like a gimbal, it is not necessary to maintain tight
tolerances in axial alignment between the electrical connector and the mechanical connector, and
to maintain tolerance. First, the main embodiments of the present invention are listed.
