Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a structure for attaching an operating rod to an electrical component such as a slide volume housed in a case.

[Conventional technology]

Conventionally, there is a so-called electrical assembly apparatus shown in FIGS. 5 to 8, which assembles an upper case covering a slide volume as an electrical component to a lower case to which the slide volume is fixed. This electrical assembly device includes an upper case 1 having a side frame 1a and a lower case 2 having a rising side frame 2a covered by the upper case 1. The lower case 2 includes a printed circuit board 3 attached to its bottom 2b side with screws 8, and the printed circuit board 3 includes a slide volume 4 and a connector 9 on its upper surface. The slide volume 4 includes a lever 5, into which an operating rod 6 is inserted. A U-shaped notch 7 is provided at the upper edge of one of the rising side frames 2a of the lower case 2, through which the operating rod 6 can be inserted and moved. By moving the operating rod 6, the value of the slide volume 4 can be adjusted. In addition,
10 is a spacer interposed between the bottom plate 2b and the printed circuit board 3.

[Problems to be solved by the invention] In the above electrical assembly device, the cutout recess 7 is formed at the upper edge of the rising side frame 2a of the lower case 2 so as to protrude above the slide volume as shown in FIG. When attaching the plate-shaped operating rod 6 to the lever 5,
This is to prevent the rising side frame 2a from becoming an obstacle during the mounting, since the hole 6a formed in the operating rod 6 must be mounted from above onto the engagement portion 5a formed at the tip of the lever 5. This notch recess 7
is closed by the side frame 1a that covers the rising side frame 2a from the outside, leaving an area (opening) S that does not interfere with the movement of the operating rod 6.

However, according to such a configuration, the width W of the opening S cannot be made too wide to prevent foreign matter from entering or due to design problems. the result,
The height of the side frame 1a had to be set to a constant value. That is, when using a commercially available standard slide volume 4, the vertical dimensions of the printed circuit board 3, the notch recess 7 of the lower case 2, and the lower end of the upper case 1 cannot be designed freely, and there are design and structural limitations. There were other problems.

This idea was devised in view of the above problems, and its purpose is to provide an electrical assembly device in which the vertical dimensions of the printed circuit board and the lower end of the upper case can be freely designed, eliminating design and structural limitations. .

[Means to solve the problem]

In order to achieve the above object, this invention forms a notched clamping groove at one end of the operating rod that extends in the direction of movement of the lever to clamp the lever, and extends from the end of the notched clamping groove toward the opening of the groove. A protrusion is formed on the groove wall at a distance approximately the same as the width of the lever to prevent the lever from coming off in the direction of the opening, and the operating rod is attached to the lever via the notched holding groove. It is characterized by

[Effect]

In the electrical assembly device having the above configuration, the operating rod does not have to be attached to the lever from above.

Therefore, since the rising side frame of the lower case does not become an obstacle during installation, there is no need for a conventional U-shaped notch. Therefore, there is no need to lengthen the side frame of the upper case to cover the notch recess.

〔Example〕

The present invention will be described below with reference to the embodiment shown in FIG.
Please refer to FIG.

In this embodiment, the same members and parts as those in the conventional example described above are designated by the same reference numerals, and the explanation thereof will be omitted.

In the electrical assembly device according to this invention, the operating rod 11 is made of a flat plate material of, for example, elastic synthetic resin that can be deformed to some extent, and has a base 12 and an operating part 13 integrated at the center of the side of the base 12. We are prepared. The base 12 is one end of the operating rod 11, that is, the lever 5
It is provided at a position corresponding to , and its shape is formed into a rectangular shape with a wide width. This base portion 12 is provided with a notch holding groove 14 and a coin removal portion 15,
The notch holding groove 14 is formed in a shape to hold the lever 5 along the movement direction so that the lever 5 can be fitted and engaged, and is provided with an opening 14a. This notched holding groove 14 is formed from one side edge of the base 12, and the terminal end 14 of this notched holding groove 14 is formed from one side edge of the base 12.
A protrusion 16 is formed from the groove wall, that is, the side wall, at a distance approximately the same as the width of the lever 5 from b toward the opening 14a of the groove, and this protrusion 16 prevents the lever 5 from coming off from the opening 14a. It's summery. The coin removal part 15 is located on the side of the rising side frame 2a of the lower case 2, and the dimension A (see FIG. 3) with respect to one end of the square elongated hole 17 provided in the rising side frame 2a is the same as that of a one-yen coin, for example. Make it smaller than about 20mm,
Eliminates intrusion of coins.

The operating portion 15 is inserted into the other end of the elongated hole 17 so as to protrude outward from the rising side frame 2a. This elongated hole 17 is provided not at the upper part of the rising side frame 2a but at a position corresponding to approximately the middle of the lever 5. Therefore, the operating rod 11 is inserted into this elongated hole 1.
The protruding direction of the lever 12 extends in the vertical direction via the lever 7 .

Next, the effect will be explained.

In the electrical assembly device having the above configuration, the lever 5
The operating rod 11 may be attached to the base portion 12 so that the tip of the lever 5 is held in the notched holding groove 14 of the base portion 12. This attachment does not have to be done from the upper side of the lever 5, but can be done through the elongated hole 17, so the elongated hole 17 does not need to be formed in the upper part of the rising side frame 2a. Therefore, the side frame 1 of the upper case 1
a can have a short shape.

[Effect of idea]

As explained above, this device forms a notched clamping groove at one end of the operating rod that extends in the direction of movement of the lever to clamp the lever, and also extends from the end of the notched clamping groove toward the opening of the groove. A protrusion is formed from the groove wall at a distance approximately the same as the width of the lever to prevent the lever from coming off in the direction of the opening, and the operating rod is attached to the lever through the notched holding groove. Since it is characterized by being able to
There is no need to put it on from above. Therefore, it is not necessary to form a long hole through which the operating rod is inserted in the upper part of the rising side frame of the lower case. Therefore, even if a commercially available standard slide volume is used, the vertical dimensions of the printed circuit board and the lower end of the case 1 can be freely designed, and restrictions on design and structure are lifted. Furthermore, since a protrusion is formed in the notch holding groove, the structure is such that the operating rod can be prevented from coming off as much as possible.
