DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a microswitch
mounting structure for a microphone. (1) IPorll In conventional microphones, in order to attach a
micro switch for turning the microphone on or off, it has been customary to attach a microphone
case with a screw. Therefore, mounting of the microswitch to the microphone case at the time of
assembly and repair, and connection of the lead wire to the microswitch are bothersome,
laborious, expensive, or disadvantageous in handling or inconvenience. It was In view of such a
drawback of the present invention, the present invention divides the microphone case into a
front case and a rear case, and restricts the movement of the micro switch under L in the front
case and / or the rear case. Provides a microphone micro switch mounting structure that is
extremely simple to install by limiting the movement of the micro switch under-L, left and right
and back and forth in cooperation when both cases are joined. It is characterized in that it does
not use a special attachment means such as a screw. The configuration of the present invention
will be described below with reference to the drawings. (2) 1 is a microphone case, and is formed
such that a first half case 2 and a second half case 76 are joined by respective mating surfaces 2a
and 2b. Reference numeral 4 denotes a micro switch fitting q formed at a predetermined position
of the second half case 6, which restricts the lateral frames 7a and 7b to which the tod faces 6a
and 6b of the main body 6 of the microswitch 5 abut Rod-like fitting pieces 9a, 9b fitted in
through holes 6d, 6d bored in the main body 6 of the micro switch 5 are projected in the case

1IIJ 3b. As shown in FIG. 1, the micro switch 5 is fitted to the microphone / hig fitting portion 4
so as not to move L downward and left / right. IOa, lOb, IOa and IOa are cross-pieces protruding
from the inner surface 3b of the case, and their front and rear positions of the micro switch 5 are
determined by their heights. On the other hand, on the case inner surface 2b of the front half
case 2, a rectangular projection 11 is provided at a position corresponding to the micro switch
fitting portion 4. When the front half case 2 is joined to the rear half case 3, The front surface of
the microswitch 5 is pressed by the projection] 1 and regulated so as not to move in the front /
rear direction 1 (3) □ -J. Iia is a recessed portion cut into the rectangular projection 11, 12 is a
switch lever-113 is a pin plunger, and the micro switch 5 is turned on and off by the rotation of
the water and chileha 12.
Reference numeral 14 denotes a switch member, which is provided on a rotary member 17
having a projecting portion 16 projecting through a window 15 formed on the microphone case
1, an elongated hole formed on the projecting portion 16, and the projecting portion outside It
consists of the movable piece 19 and the pressing piece 2] connected to the iJ moving piece 9 by
the connecting bin 20 through the long hole inside the protrusion. When the movable member
19 is in the I-position (in the drawing), the suppression member 21 is slid toward the switch
member 14, and the projection 22 at the lower end thereof presses the switch lever 12 and the
microswitch 5 is always operated. It acts as a switch to turn ON, and it acts as a switch which acts
only when the movable member] 9 or the lower position presses the projection portion 6 inward.
なお、2ろはマイクロスイッチ5の1! There is (4) in the pole terminal. In FIGS. 7 to y, the
microphones in the microphone case 1 are omitted. Moreover, the micro switch fitting part 4 is a
horizontal frame 7a. The 7b1 restricting pieces 8a and 8b may be omitted and only the fitting
piece 10 may be used, of course, the lateral frames 7a and 7b and the restricting pieces 8a and
8h1 may be replaced with the fitting pieces 9a and 9b. Even in the case of y supporting frames in
which only the corners 6e, 6f, 6g and 6h fit, or two supporting frames in which only the opposite
/ paired corners fit, the purpose of the present invention is to fully exhibit its intended function. I
can do it. Further, in the above embodiment, the heights of the horizontal frames 7a and 7b, the
restriction pieces 8a and 8b, and the fitting pieces 9a and 9b are positioned up to the micro
switch 5-h plane, or are not particularly required. It is needless to say that the lacquer of the
height of the micro switch 5 is sufficient if the position of 5 is regulated. Furthermore, the
rectangular projection 11 does not have to press the entire top surface of the microswitch 5, and
may only push a part of the top surface. Also, in the above case, either 1 (5) or 1V11 micro
switch fitting portion 4 is provided in only one case, or fitting portions are provided in both
cases. When it is joined, the micro switch 5 can be fitted and pressed to regulate. As described
above, the micro switch is attached by fitting to the microphone case without using a special
attachment such as a screw as described in the above, so the installation of the micro switch
becomes extremely easy, and the assembly efficiency is achieved. Has an excellent effect of
significantly
