Abstract

(57) [Summary] [Purpose] To simplify the structure and installation work of a clamper that fixes a flexible board to the foot of a case. [Structure] A foot portion 1a is formed on a case or base 1 of an electric appliance or the like. A projection 1b is formed on the foot portion 1a. A through hole 2a is formed in the flexible substrate 2 to fit into the protrusion 1b. A hole 3a is formed in the clamper 3 to fit into the projection 1b. The clamper 3 has an engaging portion 3 that engages with the foot portion 1a.
form b. Then, a through hole 2a and a hole 3 are provided in the protrusion 1b.
a, and connect the clamper 3 via the flexible board 2.
is engaged with the leg portion 1a. Thereby, the work of fixing the flexible substrate 2 by the clamper 3 can be simplified.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is a flexible wire that is wired from inside the case or base of electrical appliances etc. to the outside of the case. The structure of a clamper for flexible circuit boards for fixing flexible circuit boards to cases and bases. related.

0002

[Conventional technology]

Conventionally, as this type of technology, for example, there is a clamper 4 as shown in FIG. . The clamper 4 is a belt-like binding band. 5 is a case of electrical appliances, etc. , a flexible board 6 for connecting to connectors and other electrical appliances. The case The base 5 has a foot portion 5a protruding from its lower end. The flexible substrate 6 is a protective member It is fixed to the leg portion 5a by the clamper 4 via the clamper 7. The protective member 7 is made of urea. Tangomu etc.

0003

[Problem that the idea aims to solve]

The conventional clamper 4 described above attaches the flexible substrate 6 to the cage via the protective member 7. is fixed to the foot portion 5a of the base 5. The clamper 4 secures the flexible substrate 6. The work of winding the protective member 7 around the leg portion 5a is inefficient and requires many man-hours for assembly. Ma Furthermore, the means for fixing the flexible substrate 6 by the clamper 4 requires the protective member 7. Therefore, there is a problem that the number of parts is large and the cost increases.

0004

[Means to solve the problem]

The structure of the clamper for flexible circuit boards according to the present invention is that a protrusion is formed on the case. Or a flexible substrate with a hole and a through hole that matches the protrusion or hole. and a hole or protrusion that fits into the protrusion or hole, and the flexible base The clamper is held in the case via a plate, making it inexpensive. This provides a clamper that is easy to install.

【Example】

Hereinafter, based on FIGS. 1, 2, and 3, the clamp for flexible circuit board according to the present invention will be explained. A preferred embodiment of the structure of the par will be described in detail.

[0006] 1 is, for example, a case or a base of an electrical appliance such as a switch or a connector. The case 1 has a foot portion 1a formed at its lower end. 2 is pulled out from inside case 1. It is a flexible circuit board. Flexible board 2 has one end connected to case 1. , and the other is connected to an electrical device such as a connector (not shown). The flexible The substrate 2 has a through hole 2a that fits into the protrusion 1b of the foot portion 1a. 3 is the fu This is a clamper for holding the flexible substrate 2 on the foot portion 1a. Clamper 3 A hole 3a is formed to fit into the protrusion 1b. The clamper 3 is attached to the foot portion 1a. Engagement portions 3b to be engaged are formed at both ends.

[0007] The structure of the flexible circuit board clamper according to the present invention is as described above. Next, the installation procedure and operation will be explained in detail.

[0008] When fixing the flexible board 2 to the foot part 1a, first remove the flexible board from inside the case 1. Pull out the hard board 2. The protrusion 1b is fitted into the through hole 2a. And flexi The clamper 3 is engaged with the foot portion 1a through the bull base plate 2, and the hole 3a is connected to the protrusion 1. Fit into b. With the above steps, the flexible board 2 can be easily attached using the clamper 3. It can be fixed to the foot portion 1a.

[0009] The flexible substrate 2 is fixed to the leg portion 1a by the clamper 3, so it is not affected by external force. This makes it possible to prevent the soldered portion from coming off due to such problems.

0010 As described above, as an embodiment of the present invention, the protrusion 1b is placed on the case 1, and the hole 3a is placed on the clamper 3. The details of the formation were explained in detail. However, the protrusion 1b is used as the clamper 3, and the hole 3a is used as the case. Similar actions and effects can be obtained even when the film is formed in the base 1.

[0011]

[Effect of the idea]

The structure of the clamper for flexible circuit boards according to the present invention has the above-mentioned configuration and operation. This reduces the number of man-hours required for fixing flexible circuit boards using clampers. , the efficiency of installation work can be improved. In addition, this invention can be applied to flexible substrates. Since no protective member is required, the number of parts and costs can be reduced.
