Further, even when the mounting position of the mounting part is changed, the mounting position of the mounting body to the mounting part and the engaging hole of the holding body which engages with the engaging part of the mounting body can be arbitrarily set. The attachment body that is attached to the attachment component whose attachment position is to be changed can be easily handled even after the attachment position is changed.

Furthermore, in the case of adding a mounting part, the number of engaging parts of the mounting body mounted on the mounting part does not exceed the number of engaging holes of the holding body. By attaching a corresponding attachment body to the attachment part and engaging an engagement part of the attachment body with an arbitrary engagement hole of the vacant holding body, addition of the attachment part can be easily coped with. It is a thing.

Next, in the above-mentioned one embodiment, the attachment body has only a function as a spacer so that the body portion of the attachment body allows the height position of the upper end surface of the prevention portion of the attachment body to coincide with each other. However, when an external force such as a drop impact is applied, the attaching body also has a shock absorbing function to absorb the impact so that the main substrate is not cracked due to its reaction, and the following other examples are given. Will be described with reference to FIG.

Attachment 8 used in the component holding device of the present invention
Reference numeral 0 has a holding portion 81, which is an attachment portion for holding the free end of a mounting component (not shown) at one end, and engages with an engaging hole (not shown) in the holding body at the other end. With the part 82,
The base of the engaging portion 82 is provided with a preventing portion 83 for preventing the attaching body 80 from being pulled out through an engaging hole (not shown) of the holding body, and the base portion of the holding portion 81. When attaching the attachment body 80 to the attachment component (not shown) by sandwiching the attachment component (not shown) on the attachment component (not shown)
A position restricting portion 84 that restricts an attachment position of the attachment part (not shown) with respect to the attaching body 80 by contacting the free end surface of the position adjusting portion 84 and the preventing portion 83. The upper end surface (the end surface on the side where the engaging portion 82 is located) of the prevention portion 83 when the attachment body 80 is attached to the attachment component (not shown) has a dimension thereof. The external force such as a drop impact is absorbed by the body portion 85 set so as to match the lower end surface (end surface on the cabinet side) of the holding body (not shown) when attached to the cabinet (not shown). The elastic portion 86 for cushioning the impact and contacting the free end surface of the mounting part (not shown) when the elastic part 86 is excessively deformed, and the limit movement of the mounting part (not shown) It is provided with a limit position regulating section 87 for regulating the position.

The attachment body 80 having the above-described structure is attached to the attachment body 80 by holding the attachment body 80 by clamping the attachment body 80 with an external force such as a drop impact. (Not shown)
, The free end surface of the mounting component (not shown) presses the position regulating portion 84 upward (direction of arrow B), the elastic portion 86 is bent and deformed, and shock is generated. The main board (not shown) on which the above-mentioned attachment parts (not shown) are mounted can be relaxed to prevent cracks and the like.

In the above operation, when the elastic portion 86 is excessively deformed, the free end surface of the mounting component (not shown) comes into contact with the limit position regulating portion 87. Damage of the mounting part (not shown) and the main board (not shown) on which the mounting part (not shown) is mounted by suppressing movement (lifting) of the mounting part (not shown) exceeding a limit value. Can be prevented.

Further, in the case of the attachment body 80 of the above-mentioned other embodiment, since the elastic portion 86 of the attachment body 80 absorbs the dimensional variation of the attachment component (not shown), the attachment component is always present. (Not shown) can be held with an appropriate force.

Further, in the above-described one embodiment and other embodiments of the present invention, by unifying the distance between the free end surface of the attachment part and the holding body, the size of the body portion of the attachment body is also unified. The body can be made into a standard part, and the holder having the engaging holes and the mounting holes with the same vertical and horizontal pitches can be processed to the required length by using a long standard member in advance in the longitudinal direction. Therefore, it is possible to reduce costs by eliminating dedicated parts.

[0027]

Since the component holding device of the present invention has the above-mentioned structure, even if the attachment position or the attachment direction of the attachment component is changed, the attachment body is attached to the attachment component. Even when the position is changed or the engaging hole of the holding body that engages with the engaging portion of the attachment body is changed and engaged, or the attachment part is added, the engagement of the vacant holding body is changed. By engaging the engaging portion of the attachment body that attaches to the additional component using the dowel hole,
It is possible to hold the mounting component on the mounted body by easily adapting to the change of the mounting position and mounting direction of the mounting component and addition of the mounting component.
