Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a holding structure for a flat cable.

(Background of the idea) One end of the flat cable is fixed to the board by soldering. By the way, when carrying such a board with a flat cable, the flat cable is generally lifted up, which may cause the soldered portion to peel off. Therefore, in order to prevent the soldered portion from peeling off, the flat cable is pressed against the board using a holding metal fitting.

As shown in FIG. 1, the conventional flat cable holding structure is such that both ends 11, 11 of a holding fitting 1 made of a U-shaped plate are connected to an elongated hole 21 provided in a substrate 2.
21 and press down the flat cable 3,
The flat cable 3 was pressed against the board 2 by bending both ends 11, 11 of the holding metal fitting 1 inward.

However, such a presser structure is limited to the presser metal fitting 1.
A tool is required to bend both ends 11, 11 of the substrate 2, and the presser metal fitting 1 cannot be easily removed from the substrate 2, and once bent, the presser metal fitting 1 has a tendency to bend and cannot be reused. It was hot.

(Purpose of the invention) The object of the invention is to provide a holding structure for a flat cable that allows the holding fitting to be easily attached to and removed from a board, and also allows the holding fitting to be reused any number of times.

(Embodiment of the invention) An embodiment of the invention will be described below with reference to FIGS. 2 and 3. The holding fitting 4 is made of a wire material, and includes a cable holding part 41 extending longer than the width of the flat cable 3, and a cable holding part 41 extending approximately perpendicularly from both ends of the cable holding part 41 by the thickness of the flat cable 3 and the board 2. first step portions 42, 42, board holding portions 43, 43 extending following the first step portion 42 and substantially perpendicular to the first step portion 42 and the cable holding portion 41, respectively; Second step portions 44 , 44 which are parallel to the first step portion 42 and extend by the thickness of the board 2 following the board holding portion 43 on the side of the first step portion 42 , and the cable holding portion 41 It has hook parts 45, 45 which are parallel to and extend from the second step part 44 on the opposite side to the cable holding part 41. The substrate 2 has a slit 22 into which the first step portions 42, 42 are inserted.
22, and holes 23, 23 into which the second step portions 44, 44 are inserted are formed.

Next, the attachment of the presser fitting 4 will be explained. As shown in FIG.
Press 4 and 44 with your fingers to bend them inward. In this case, since the first step portions 42, 42 are also twisted, the presser metal fitting 4 is elastically deformed without difficulty. The cable holding part 41 can also be expected to bend as shown by the two-dot chain line, and from this point as well, the holding fitting 4 is easily elastically deformed.

In this state, as shown in Fig. 2, the flat cable 3 is soldered to the slit 2 of the board 2.
2, 22, and insert the hook portions 45, 45 into the holes 23, 2 from the bottom surface of the board 2.
3 and position it on the top surface of the board 2.
Release the pressure. As a result, the second stepped portion 4
4 and 44 return to their original positions and are stopped by being caught in the holes 23 and 23 of the board 2, and the holding fitting 4 is attached to the board 2, and the flat cable 3 is held down by the cable holding portion 41 of the holding fitting 4.

In this way, the presser metal fitting 4 is attached to the substrate 2 by elastic deformation, so no tools are required.
It is extremely easy to install and remove as many times as you like.

(Effects of the invention) As is clear from the above explanation, according to the invention, the presser metal fitting is made of wire and formed into a shape that is easily deformed elastically, so it can be attached and removed very easily and any number of times. I can do it.
