Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a method for fixing parts.

(Prior Art) FIGS. 3 and 4 show, as an example of a conventional method of fixing components, a method of fixing a light receiving element to a cassette holder in a video recorder, for example.

In this conventional example, when fixing the light receiving element 2 to the cassette holder 1, the light receiving element 2 is first set in the light receiving hole a of the cassette holder 1 together with the relay board 3 attached thereto.
After placing the cushioning material 4 on top of that, the plate spring 5 with a U-shaped cross section, which is a fixing metal fitting, is placed over the mounting part 1a provided on both sides of the light receiving hole a, and then attached to the side wall 5a of the plate spring 5. The structure is such that the tab 60 is fitted into the protrusion of the mounting portion 1a.

(Problem to be Solved by the Invention) However, in the above fixing method, the plate spring 5 is attached to the cassette holder 1 by fitting the 60 with the protrusion. A certain level of height was required for the side wall 5a of the leaf spring 5, where the mount is provided, and the mounting portion 1a, where the protrusion is provided.

For this reason, there is a problem in that the mounting height of the light receiving element 2 becomes high, which hinders miniaturization of the device.

This invention was made in order to solve these conventional problems, and it is possible to significantly reduce the height required for mounting parts, thus making it possible to reduce the size of the equipment. The purpose is to provide a fixation method.

[Means for solving problems]

A method for fixing a component according to the present invention is such that the component is fixed to a member to be fixed by using the restoring force of a linear elastic member that is flexibly deformed.

[Effect]

By the above method, the parts are flexibly deformed bar springs.
Since it is fixed to the member to be fixed by the original force, the height required for mounting the part can be as low as the height of the part plus the thickness of the bar spring.

〔Example〕

FIGS. 1 and 2 are diagrams showing an embodiment of the present invention and a method of fixing a light receiving element to a cassette holder in a video tape recorder, similar to the conventional example.

In the figure, 11 is a cassette holder as a member to be fixed, d and e are claws protruding from the top surface of the cassette holder 11,
1 is for hooking the ring part f of the bar spring 16 and the arm part g, which will be described later, h is a light receiving hole, 12 is a light receiving element as an attachment part, 13 is a relay board attached to the light receiving element 12, 1
4 is a cushioning material, and 16 is a rod spring which is a mounting bracket as a linear elastic member. This bar spring 16 has a ring part f formed by winding the center part of one bar spring in a spiral shape, and has arm parts g spread out at an acute angle on both sides to form a torsion spring. By squeezing the arm g, a repulsive force is generated in the circumferential direction of the bait ring f. F claws d and e are provided at positions lower than the height of the light receiving element 12.

1. Fixing of the light receiving element 12 is performed by the following procedure.

First, the light receiving element 12 is set in the light receiving hole of the cassette holder 11, and the cushioning material 14 is placed thereon. Next, the ring part f of the bar spring 16 is hooked on the claw d of the cassette holder 11, the arm part g is brought down onto the cushioning material 14, and the tip thereof is squeezed and hooked on the claw e of the cassette holder 11. Inner nail e
The width formed by the bar spring 16 is narrower than the width formed by the tip of the arm part g when no load is applied to the bar spring 16, and when the arm part g is hooked on the claw e, the arm The pressing force of part g works, and arm part g is fixed.

Further, since the arm portion g of the bar spring 16 is formed to be flexibly deformable, the arm portion g of the bar spring 16, which is hooked on the claws d and e formed as described above, is flexibly deformed. ,
The light receiving element 12 held down by the restoring force is fixed to the cassette holder 11 together with the cushioning material 14.

As described above, in this embodiment, when fixing the light receiving element 21, both ends of the rod spring 16 placed on it are supported at a lower position than the light receiving element 12, so the cushioning material 14 is reduced to the minimum necessary level. If a thin one is used, the mounting height h2 of the light-receiving element 12 will be a thin cushioning material 1 at the height of the light-receiving element 12.
4 and a stick spring! 6, and the height required for installation is ii (lower) than in the past.Therefore, devices such as video tape recorders and the like can be downsized.

Furthermore, in the case of this embodiment, the bar spring 16 can be easily removed by the reverse procedure to the above-mentioned procedure, so the advantage is that the fixing and removing can be repeated as necessary, making workability and maintenance easier. There is.

In addition, in the above embodiment, the cushioning material 14 was interposed between the light receiving element 12 and the bar spring 16, but in general, the insertion of the cushioning material is omitted if there is no problem with the insulation, strength, etc. of the parts. It is possible to do so. With such a configuration, the height required for mounting parts can be further reduced.

〔Effect of the invention〕

As explained above, according to the present invention, the restoring force of the flexibly deformed parts is used to fix the parts, so the height required for mounting the parts can be significantly reduced.
The device can be made smaller.
