In general, when a large speaker is attached to a speaker box such as stereo and operated, air pressure is generated to cause a difference in air pressure between the inside and the outside of the speaker box. As a result, when the air flows from the inside of the speaker box to the outside or in the opposite direction, noise such as "hy-hy-hy-yu" is generated, and the sound generated from the speaker and the human-mixed sound effect are reduced. Therefore, the speaker box is necessarily required to have a degree of sealing that can withstand (2) changes in air pressure, but at the same time a product having similar effects is also required for the wire connector used for the speaker box. Ru. Therefore, in the conventional t * connector used for the speaker box, a method of sealing the clearance of the fitting portion between the base body incorporating the wire connection mechanism and the housing with a resin such as rubber paste or with the speaker box A method has been adopted in which an elastic body is fitted and sealed on the entire surface of a wire connector in contact. In the former method, the processing cost for sealing occupies about 40% of the whole product, and there is also a problem in terms of reliability. Also, the latter method has the disadvantage of increasing the number of parts. Therefore, the object of the present invention is to solve the above-mentioned drawbacks of the prior art. Hereinafter, one embodiment of the present invention will be described with reference 01-05-2019 1 to the drawings. In Fig. 1 to Fig. 3, the frame is an insulating base molded of synthetic resin, and mounting holes α and so on at four corners of a substantially square plate bulge downward at the central portion and the bottom wall is stepped. Recesses u31 are respectively formed. At the center of one side of the recess 03, a container receiving portion Q41 which bulges further downward is formed. On the bottom wall of the container housing portion a4, six circular through holes u9 and two rectangular through holes q8 whose opening area is reduced as opening to the back side are respectively drilled, and Two U-shaped protruding projecting walls 1η are formed on the surface of the bottom wall. Further, on the back side of the base U, as shown in FIG. Jp4, there is a tapping hole Buddha located at the back of the recess 0 and at the same height as the bottom wall of the container storage I at the center. (4) There are seven pillars U and two pillars higher than that, respectively. A mounting plate Qυ is fixed to one of the columns al by a screw (2), and both ends of a capacitor (2) constituting the speaker network are supported by the mounting plate @, and a coil il + is mounted on the column ■. The coil bobbin (1a) is inserted and held by the stop ring. C (11 is a wire connection mechanism. As shown in FIG. 5, the wire connection mechanism 611 is an insulating container (mostly) molded of a synthetic resin, a conductive terminal (mostly), and an insulating wire suppressor molded of a synthetic resin. It consists of the body and the spring. The body (9) is formed in the shape of an open lower surface, and at the periphery of the lower surface (the six projecting countries inserted into the circular through hole u9 of ill are inside the center left and 5): A partition wall (div) is provided which is divided into each chamber 6η of ++ −. In each chamber @, a wire insertion hole (d) which is expanded toward the upper surface in the upper wall, a window hole I is opened from the upper portion of the front wall to the earth wall, and the base Protrusions that face the projecting wall aη of +111 and receive the lower end of the spring (t) are formed on the guide wall forming the guide groove between the inner wall and the rear wall at the rear inside. In the example of the terminal, an electric wire gripping piece (C) whose front end is formed into a concave arc by cutting and rising at a right angle to the central child plate inserted into the guide groove 10 of the body □□□ and the insertion position in the guide groove i4z Are formed respectively, and the upper end of the central flat plate has an insertion hole axis η facing the lower surface of the container C (the wire insertion hole (2) of 2) At the lower end, the wire guide piece (c) has two (6) pieces of holding pieces substantially in the shape of a downward arrow and a wire connecting piece (d) projecting to the back side through the rectangular through hole tank of the base plate. Are formed respectively. The plate thickness of this terminal example is slightly larger than the hole width of the rectangular through hole t1e, and the lower end of the wire connection piece ω is chamfered, and this wire connection piece − is a rectangular through hole (1G1 of the base q). Forcibly press-fit into the above, the degree of sealing is enhanced by the elasticity of the resin of the base a. The electric wire restraining member (conductive member) is a conductive pressing member in which a cylindrical shaft 6υ rotatably held in the holding piece t4S of the terminal (at) on both ends at the lower end has a front end cut away in the middle at the front end An 01-05-2019 2 operation portion Q is formed at the upper portion thereof to project outward from the window hole 14G of the container ■, and a spring receiving groove (ii) for receiving the upper end of the spring field is formed on the rear surface of the middle portion. (7) · · · 1, 546 Next, the assembly method will be described. First, the central flat plate of the terminal is inserted between the guide grooves 1421 of the container, and the insertion hole 171 of the wire guide piece at the upper end is exposed to the lower surface of the wire insertion hole. . Then, engage the shaft 6 'of the wire suppressor (to) with the holding piece-of this terminal (to) and make the operation part (to) project outward from the bite of the body (from), Spring liquor is inserted between the spring receiving groove and the projection 1411. Then, since the upper portion of the wire pressing body (the first end) is biased toward the upper edge side of the window with the shaft 61) as a fulcrum, each component is held in the body @. Next, the container Q in this state is inserted into the container housing portion I of the base body + 11), and the projection on the bottom surface of the body is projected to the back side through the circular through hole Q9 of the base body. Then, the circular through hole seals the gap 9 by thermally deforming the protrusion (to the top) projecting to the back side. At this time, the lead (8) connecting piece at the time of the terminal is pushed into the rectangular throughhole all of the base body 強制 forcibly, that is, in a state in which the gap of the rectangular through-hole 密閉 is tightly sealed and stably projected. While being held, the shaft 6N is prevented from escaping since the lower end of the holding piece abuts against the inner bottom surface of the base body t1. Next, on the back side of the base body Qυ, the mounting plate (21 is fixed with a screw @ to one of the support columns 0, and both ends of the capacitor (2) constituting the network are supported by the plate mounting plate Qυ The coil bobbin (1a) of (1) is inserted and held by the stop ring a. Then, for wiring, as shown in Fig. 6, connect one end of the coil (1) to one terminal [Yes] projecting to the back side of the base a and connect one end of the capacitor (2) to the other terminal 33. Do. Also, between the other terminal port and the other end of the coil (1) and between one end (9) and the other end of the capacitor (2), When attaching this wire connector to the speaker box, connect each speaker (sp). Now, an operation of connecting a wire to the wire connector assembled as described above will be described. First, when the operation part Q of the wire suppressing member is rotated against the spring field, the pressing piece 62 moves from the position at the time of the wire insertion hole to the opposite side to the terminal. In this state, when the electric wire is inserted into the electric wire insertion hole (d) and the pressing of the operation part mark is released, the electric wire suppressor (d) rotates counterclockwise in the diagram with the shaft 6 inset as a fulcrum by the elasticity of the spring field. The suppression piece 53 pushes the electric wire toward the terminal (most) side to electrically connect the both. In addition, the operation for releasing the connection of the electric wire can resist the elasticity of the spring can on the operation part of the electric wire pressing body (mostly) [If the pressure piece 6a is separated from the terminal (mostly), the electric wire can be pulled out . According to the present invention, a plurality of projection through holes and at least one terminal through hole are respectively formed in a synthetic resin 01-05-2019 3 base body, and the projection penetration is carried out in a synthetic resin container attached to the surface side of the base body. A plurality of projections projecting to the back side through the holes are formed, and after the projections of the body are inserted into the projection through holes of the base body, clearance of the projection through holes is obtained by caulking the projections projecting to the back side. While sealing, the cross-sectional shape of the terminal of the wire connection mechanism incorporated between the base and the housing is formed to be slightly larger than the terminal through hole, and this terminal is press-fit into the terminal through hole of the base Since the clearance of the terminal through-hole is sealed by the elasticity of the base material, that is, the elasticity of the synthetic resin, the reliability of the degree of sealing is improved as compared with the conventional method in which the clearance is banded by resin or the like Improve On can Rukoto, simple K and can be inexpensive, it can be manufactured without increasing number of parts. 01-05-2019 4
