Detailed Description

The technical solution of the present invention will be further described with reference to the following specific examples, but the present invention is not limited to these examples.

It should be understood that the structures, ratios, sizes, etc. shown in the drawings of the present application are only used for matching with the contents disclosed in the specification, so as to be known and read by those skilled in the art, and are not used for limiting the limit conditions that the present invention can be implemented, so that the present invention has no technical essential meaning, and any modification of the structures, change of the ratio relationship or adjustment of the sizes should still fall within the scope of the present invention without affecting the functions and the achievable purposes of the present invention. Meanwhile, the terms such as "upper", "lower", "left", "right", "top", "bottom", "middle" and "one" used in the present specification are used for clarity of description only, and are not used to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof are also considered as the scope of the present invention without substantial changes in the technical content.

Referring to fig. 1 to 3, the combination switch of the present invention includes a lever 1 and a FPCB 2, where the lever 1 includes a flange 10 and a main body 11, and the FPCB includes a flange mounting portion 20 and an extension 21. As shown in fig. 3, a projection is provided on the flange portion 10 of the lever, and fixing holes matched with the projection are respectively provided on the flange mounting parts 20 of the FPCB to fixedly mount the flange mounting parts 20 of the FPCB to the flange portion 10 of the lever; and a card slot 110 for accommodating the extension 21 of the FPCB 2 is provided on the body portion 11 of the lever, and at least one clamping plate 111 is provided at one side of the card slot 110 for clamping and fixing the extension 21 of the FPCB.

The utility model discloses an in the above-mentioned gang switch, come FPCB to fix to the lever through the joint mode, compare traditional riveting fixed mode, this fixed mode has reduced the switch fault rate when improving production efficiency.

It is understood that there is no particular limitation in the number of the catching plates 111, but preferably, as shown in fig. 4, at least one catching plate may be provided at both sides of the catching groove 110, respectively, to improve the fixing reliability of the extension 21 of the FPCB.

When all being equipped with the joint board in the both sides of draw-in groove, cause FPCB's damage easily when the fixed FPCB of installation, to this technical problem, in further technical scheme, joint board 111 can adopt and can turn over a joint board. Specifically, can turn over a joint board and can include the clamp plate part and turn over a part, wherein the clamp plate part is used for realizing pressing fixedly to FPCB, turns over a part and is used for realizing turning over of joint board, wherein, turn over a thickness that partly is less than the thickness of clamp plate part to in order to turn over at the joint board and compress tightly carry on spacingly to the joint board behind the FPCB the homonymy position department that sets up the joint board of draw-in groove is equipped with corresponding buckle structure.

With regard to the arrangement position of the snap structure, it is more preferable that the card slot is provided at the opposite side position of the card plate. For example, the right side position department at the draw-in groove is fixed to the joint board, and its corresponding buckle structure sets up in the corresponding left side position department of draw-in groove to after rolling over the joint board and compress tightly the FPCB, the distal end of joint board is fixed through the buckle structure of draw-in groove opposite side, thereby makes spacing fixed more reliable, under this situation, the length of joint board need be long enough in order to be can stride across the draw-in groove and fix to the opposite side of draw-in groove.

In addition, in order to meet the requirements of some combination switches, as shown in fig. 1 to 3, the lever 1 may include two flange portions 10, and in this case, the FPCB 2 includes two flange mounting portions 20, and the FPCB further includes a connecting portion 22 interposed between the two flange mounting portions 20. In order to improve the fixing reliability of the FPCB, a clamping groove for receiving the connecting portion 22 may be provided between the two flange portions 10, and a clamping plate 112 for clamping and fixing the connecting portion 22 of the FPCB may be provided between the two flange portions 10 of the lever 1.

Since it is often necessary to bend the connection portion 22 of the FPCB with respect to the two flange mounting portions 20 in the mounting of the FPCB, in order to facilitate the bending, as shown in fig. 5, a right-angle bend may be provided at the adjacent place of the connection portion 22 of the FPCB and the two flange mounting portions 20.

Further, since the FPCB may be damaged when the FPCB is bent, a copper foil 23 may be further added at the right-angle bent portion of the FPCB.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and improvements can be made without departing from the inventive concept, and all of them belong to the protection scope of the present invention.
