Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixture applied to electronic equipment such as a relay amplifier of a proximity switch.

[0002]

2. Description of the Related Art Conventionally, as a fixture for electronic equipment, there is one shown in FIGS. 6 and 7, for example. The fixture shown in FIG. 6 is composed of a pair of upper and lower holders 1 and 2, and
Are formed with facing arc-shaped recesses 3 and 4, respectively. In addition, in this fixture, the electronic device can be held by the recesses 3 and 4 by screwing.

On the other hand, the fixture shown in FIG. 7 is made of a synthetic resin or the like, and has a pair of claw portions 6 which are opposed to both ends of the pedestal portion 5. Then, in this attachment, the claw portion 6
By elastically deforming the electronic device, the electronic device can be detachably held.

[0004]

However, since the former fixture requires screwing work, it takes time to mount the electronic device and the work is troublesome.
On the other hand, with the latter fitting, the electronic device can be easily attached and detached, but since the electronic device must be mounted against the spring force of the claw portion 6, an unreasonable force is applied to the electronic device. Sometimes it was added and damaged.

SUMMARY OF THE INVENTION In view of the above problems, it is an object of the present invention to provide a mounting fixture for electronic equipment which can be easily attached and detached and can be operated with one touch.

[0006]

According to the present invention, in order to achieve the above-mentioned object, the plate-shaped body is formed into a substantially U shape, and both end portions of the electronic device can be attached to and detached from the standing pieces formed at both end portions. And a pressing portion for elastically deforming one of the upright pieces to release the locked state with the electronic device, and the electronic portion is provided at the center of the plate-shaped body. A spring portion is formed to urge the device in a direction to be detached.

[0007]

According to the present invention, one end of the electronic device is locked to the locking portion of one standing piece, and the other end of the electronic device is engaged with the other while elastically deforming the standing piece outward. When the electronic device is pushed into the stopper, both ends of the electronic device are attached to the stoppers. Further, when the pressing portion is pressed, the upright piece is elastically deformed and the locked state between the locking portion and the end of the electronic device is released, so that the electronic device is disengaged by the biasing force of the spring portion. ..

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the electronic equipment fixture according to the present invention will be described with reference to FIGS. The fixture 10 according to the first embodiment shown in FIG. 1 is, for example, a thin plate having elasticity such as stainless steel bent into a substantially U-shape, and is notched in a central portion thereof to be bent into a substantially V-shape. As a result, the spring portion 11 is formed. The fixture 10 can be fixed by passing a screw (not shown) through the through holes 12 and 12 and fixing it to a base (not shown) (may be fixed with an adhesive).

The upright pieces 14 and 15 at both ends of the fixture 10 are perforated at the central portion, and engaging portions 14a and 15a are formed by cutting out from the edge of this hole to the upper edge. In addition, the upper end portion of the one upright piece 15 is a pressing portion 15b.

The fixture 10 is used for attaching an electronic device, for example, a relay amplifier 20 of a proximity switch.
The amplifier 20 has a cylindrical shape, and the tip portion is the detection portion 2
1, the rear end is electrically connected to a power supply device (not shown) via cords 22, respectively.

In order to attach the amplifier 20 to the fixture 10, the standing piece 14 is elastically deformed outward with the conical portion 23 on the tip side set in the locking portion 14a. When the rear end is pushed in, the conical portion 24 on the rear end side is locked to the locking portion 15a of the upright piece 15.

As described above, the amplifier 20 can be easily attached by simply pushing it in, and after being attached, the spring portion 11 urges the amplifier 20 upward so that both the engaging portions 1
It is held by 4a and 15a. In addition, when removing the amplifier 20, it is sufficient to push the pressing portion 15b backward with a finger to elastically deform the upright piece 15 outward, whereby the amplifier 20 is moved upward by the biasing force of the spring portion 11. Leave.

In the fixture 30 according to the second embodiment shown in FIGS. 2 and 3, the locking claws 33a and 33b are extended inward at the centers of the upper edges of both the upright pieces 31 and 32, and are raised. Piece 32
From both ends of the upper edge portion, pressing portions 34, 34 that further bend outward from above are provided.

On the other hand, as shown in FIG. 3, the amplifier 35 attached to the fixture 30 has lock receiving portions 3 at the lower ends of both ends.
6 and 37 are formed respectively. In the amplifier 35, when one of the locking receiving portions 36 is locked to the locking claw 33a, the standing piece 31 is pushed outward so as to be elastically deformed, and the locking claw 33b is locked. Locked to the part 37,
Similar to the first embodiment, it is biased upward by the spring portion 11 and held by the locking claws 33a and 33b. Further, when the pressing portion 34 is lightly pushed down with a finger or the like, the upright piece 32 is elastically deformed outward and the engagement state by the engagement claw 33b is released, and the amplifier 35 is disengaged by the urging force of the spring portion 11. ..

In the fixture 40 according to the third embodiment shown in FIG. 4, the upright piece 41 has the same shape as the upright piece 31 of FIG. A locking claw 43b is formed by cutting and raising. Also,
The upper edge portion of the standing piece 42 is extended outward, both sides thereof are bent upward to form facing surfaces 44, 44, and the upper edge portion is extended in opposite directions and pressed. Parts 45, 45
Has become.

The amplifier 35 is attached to the attachment 40 in the same manner as in the second embodiment. In the attached state, the pressing portions 45, 45 are the cords 3 of the amplifier 35.
8 (indicated by a chain double-dashed line in the figure). When the pressing portion 45 is pushed down, the standing piece 4
2 is elastically deformed outward and the locking claw 43b is released from the locking receiving portion 37 of the amplifier 35, so that the amplifier 35 is urged upward by the spring portion 11 and separated.

In the fixture 50 according to the fourth embodiment shown in FIG. 5, the upright piece 51 has the same shape as the upright piece 14 of FIG. 1, and the upright piece 52 is locked at the center of the upper edge of the upright piece 52 by cutting and raising. The claw 53 is formed. Further, the upper edge portion of the standing piece 52 is extended outward to form a pressing portion 54, and slits 55, 55 are formed on both sides of the pressing portion 54.

With this mounting tool 50, the amplifier can be mounted in the same manner as in each of the above-described embodiments, and after mounting, when a driver or the like is hooked on the slit 55 of the pressing portion 54 and pushed down, the standing piece 52 is elastically moved outward. Since it is deformed, the amplifier is separated by the biasing force of the spring portion 11.

The attachments 10, 30, 40, 50
Then, when a plurality of the amplifiers 20 or 35 are arranged side by side, the standing pieces 15, 32, 42, 52 are elastically deformed in the longitudinal direction of the fixture 10 and are not deformed in the width direction. There is an advantage that it can be kept small.

[0020]

As is apparent from the above description, according to the amplifier mounting tool of the present invention, the locking portion can be locked at one end of the electronic device, and the electronic device can be mounted only by pushing. Also, since it is possible to release the locked state by the locking part by simply pushing the pressing part and remove it with the biasing force of the spring part, this attachment and removal work becomes easy,
Work efficiency can be improved.
