Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for electrical components such as jacks, switches, and connectors.

Recently, as a mounting structure for this type of electrical component, for example, a pair of locking arms made of an elastic material and having a locking claw at the tip are attached to the electrical component with the locking claws facing each other. The electric component is fixed to the mounting member by engaging the locking pawl with the locking hole of the mounting member using elastic deformation of the locking arm, which is a so-called one-touch type. are being developed.

However, this device has the disadvantage that looseness tends to occur between the electrical component and the mounting member after mounting due to the elasticity of the locking arm, making it difficult to obtain a firm mounting condition.

An object of the present invention is to easily eliminate the above-mentioned drawbacks by press-fitting a padding member between the locking arms to prevent elastic deformation of the locking arm, and in addition, it is an object of the present invention to The plugging member and the locking arm are integrally molded while temporarily attached to the tip of the locking member, so that the work of press-fitting the plugging member between the locking arms can be performed more quickly and easily. The purpose is to provide a mounting structure for electrical components.

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, 1 is an electrical component, for example a jack.

The jack 1 is a normal single-type jack with a sleeve 1b for inserting and removing a plug protruding from the front surface of a case 1a made of synthetic resin.

Then, on both sides of the front of the case 1a of this jack 1,
Locking arms 2, 2 having locking claws 2a, 2a having a wedge-shaped cross section at their tips are provided oppositely, with the locking claws 2a, 2a being opposed to each other.

This locking arm 2.2 is made of an elastic material such as synthetic resin, and is molded integrally with the case 1a.

Further, on the front surface of this case 1a, each of the locking arms 2, 2 is provided.
Rectangular grooves 3, 3 are formed on the inner surface of the groove.

On the other hand, 4 is a filling member.

The stuffing member 4 includes a main body portion 4a having a ring portion 4a′ that is slidably fitted to the outer periphery of the sleeve 1b, and two legs protruding from the main body portion 4a in correspondence with the grooves 3.3. This leg piece 4 is composed of legs 4b and 4b.
b, 4b and the distal ends of the locking arms 2, 2 are connected by cuttable thin parts 8, 8, and the filling member 4 is
is integrally molded with the locking arms 2, 2 from synthetic resin or the like.

5 is a mounting member, for example, a chassis. The chassis 5 has a long hole 5a corresponding to the sleeve 1b of the jack 1, and the opening edge of the long hole 5a functions as a locking portion for locking the locking claws 2a, 2a.

The order of attaching the jack 1 to the attaching member 5 will be explained as follows.

The sleeve 1b of the jack 1 is inserted into the elongated hole 5a of the chassis 5, and the front surface of the jack 1 is pressed against the back surface of the chassis 5.

As a result, the locking arms 2, 2 are temporarily elastically deformed inward, and the locking claws 2a, 2a engage with the opening end surface of the elongated hole 5a, as shown in FIG. It is fixed to the chassis 5.

Next, from this state, the step member 4 is pressed toward the inside of the jack 1 to cut the thin parts 8, 8 where the step member 4 and the locking arms 2, 2 were connected, and remove the main body portion 4a. The fifth
As shown in the figure, it is press-fitted between the locking arms 2, 2.

Note that 6 is a decorative plate that is fitted to the tip of the sleeve 1b, and when the decorative plate 6 is fitted, the back of the decorative plate 6 is pressed against the step member 4, and the thin part 8, Cut 8,
The step member 4 is press-fitted between the locking arms 2, 2.

In addition, although the above-mentioned embodiment explained the case where the electrical component is a jack, it goes without saying that the present invention is not necessarily limited to such a device, and can be similarly applied to the installation of a switch, a connector, etc., for example. It is something.

Further, in the embodiment, when the decorative board 6 is attached, the decorative board 6 is
Although the case has been described in which the step member 4 is press-fitted between the locking arms 2 and 2 by the pressing force, the present invention is of course not limited to such an assembly method.

However, the above-described assembly method has the advantage that a special step for press-fitting the foot member 4 can be omitted.

As specifically explained above, the present invention provides electrical components with
A pair of locking arms made of an elastic material having locking claws at the tips thereof are provided opposite each other with the locking claws facing each other, and the locking claws are attached to a mounting member to allow elastic deformation of the locking arms. When used and engaged,
The electrical component mounting structure includes a step member press-fitted between the locking arms to prevent elastic deformation of the locking arm, the electric component and the step member are connected to each other, and the locking arm and the step member are connected to each other. The tread member is integrally molded with a synthetic resin material with its tips connected to each other by a cuttable thin-walled part, and the tread member is temporarily fixed in such a manner that it can be press-fitted between the locking arms. The operation of press-fitting the step member between the locking arms can be performed extremely quickly and easily.

That is, in general, when press-fitting a step member between the locking arms, the step member is positioned relative to the locking arms, the step member is then inserted between the locking arms, and then the step member protrudes. The work involved is to push out the end and press-fit it between the locking arms, but with the electrical component mounting structure of the present invention, the foot member can already be press-fitted between the locking arms through the thin part. Since it is temporarily fixed in a possible state, the above-mentioned positioning work,
There is no need for any insertion work between the locking arms, and the foot member can therefore be pressed into the locking arms very quickly and easily.

When the step member is press-fitted between the locking arms in this manner, elastic deformation of the locking arms becomes impossible, and the base end of the locking pawl is firmly crimped to the opening edge of the elongated hole of the mounting member. Therefore, there is no room for play or the like to occur in the mounting portion, and the jack etc. can be fixed very firmly to the mounting member.

Furthermore, since the step member of the present invention can be integrally molded via the locking arm protruding from the electrical component and the thin wall portion, it is extremely easy to manufacture. Since the required work and the molds and the like for manufacturing the work are all unnecessary, the cost can also be significantly reduced.
