Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a cable holder that securely holds a cable that is fixedly attached to a board by disposing its end portion at a predetermined position on the board.

For example, when removing the insulating coating from the end of a cable such as a parallel wire feeder and installing and fixing the exposed core conductor through a predetermined mounting hole in the board at a predetermined position on the board, the cable is attached to the board. It is necessary to fix and hold the object without changing its position. In such cases, the conventional method has been to bend the core conductor in the middle of the exposed core conductor of the cable to create a bent part, and to engage and fix the cable to the board at this bent part. However, this conventional method of attaching cables to the board is inevitably unstable when attached, especially when torsional force is applied to the attached cable from the outside. The problem is that it is easy to separate from the

This invention provides a cable holder which has a simple structure, allows easy operation of attaching a cable to a board, and allows the cable to be securely attached to the board.

Hereinafter, the cable holder of this invention will be described in detail based on its embodiments using the drawings.

For example, a substantially rectangular base 11 is formed of an insulating elastic material such as a synthetic resin material, and both ends of the base 11 in the longitudinal direction are bent at right angles to the plate surface of the base 11 for insertion. Pieces 12-1 and 12-2 are formed. There are recesses 14-1 between these insertion pieces 12-1 and 12-2 and the bottom plate 13 which serves as an end plate in the direction in which the insertion pieces 12-1 and 12-2 of the base 11 are bent. , 14-2 are formed, and the thickness in the direction perpendicular to the plate surface of the base 11 is thin in this portion. These recesses 14

2-2 Tapered surfaces 12-1t, 12-2t are formed on the opposing outer sides of each other so that the width in the longitudinal direction of the base 11 is narrowed with respect to the end direction. The bottom plate 13 side of the base 11 of -2t protrudes outward from each other, and protrusions 12-1p,
12-2p is formed.

At approximately equal intervals on the longitudinal centerline of the base 11 from the top plate 15 facing the bottom plate 13 of the base 11,
Cable insertion holes 16-1 to 16-4 are formed so as to penetrate through the base 11, and the inner circumferential surfaces of these cable insertion holes 16-1 to 16-4 are arranged so as to extend in the direction of the top plate 15. The opening is enlarged in the longitudinal direction of the base 11, and a second tapered surface is formed such that the opening is continuous with the adjacent one at the top plate 15 position.

With respect to the cable insertion holes 16-1 to 16-4 arranged in a straight line along the longitudinal direction of the base 11, both sides of the base 11 protrude integrally in a direction opposite to the cable insertion direction parallel to the array line. Thus, the second elastic holding piece 20-1 and the first elastic holding piece 20-2 are formed. In the embodiment, the elastic holding piece 20-1 and the elastic holding piece 20-2 are arranged to face each other, and both are formed in an asymmetrical shape. Furthermore, the outer surfaces of the elastic holding pieces 20-1 and 20-2 that do not face each other are formed into a flat shape. That is, the elastic holding piece 20-1 is formed over the entire area of the base 11 in the longitudinal direction of the base 11, and the elastic holding piece 20-2
On the inner surface facing away from the base 11, the inner plate surface moves away from the elastic holding piece 20-2 toward the end and coincides with the flat plate surface of the front surface at the end. The first tapered surface 21
-1 is formed. Moreover, the elastic holding piece 20-1
The inner surface facing the elastic holding piece 20-2 is provided with a second stepped portion 22- such that the thickness of the plate surface increases on the end side in the direction away from the base 11.
1 is formed.

On the other hand, the elastic holding piece 20-2 is set to have the same length as the elastic holding piece 20-1 in a direction perpendicular to the longitudinal direction of the base 11, and faces the elastic holding piece 20-1 over the entire area of the base 11. It is formed as follows. At the end of the inner surface of the elastic holding piece 20-2 facing the elastic holding piece 20-1 in the direction away from the base 11, an inner surface of the elastic holding piece 20-2 has a planar inner surface. Tapered surface 21- that matches the plate surface
2 is formed. Further, on the inner surface of the elastic holding piece 20-2 facing the elastic holding piece 20-1, a first plate is formed on the end side of the elastic holding piece 20-2 in the direction away from the base 11, so that the thickness of the plate surface increases on the end side. A stepped portion 22-2 is formed. The formation position of this first step portion 22-2 is shifted from the formation position of the second step portion 22-1 of the elastic holding piece 20-1 in the protruding direction of the elastic holding pieces 20-1 and 20-2. be done. Elastic holding piece 20-1
and 20-2, the respective stepped portions 22-1, 22-2 and the tapered surface 21
-1 and 21-2, and the shortest distance between the planes facing each other is set to be slightly smaller than the outer diameter of the inserted cable C shown by the dotted line in FIG.

The cable holder of this invention can be integrally molded from, for example, a synthetic resin material using a mold. In this case, a first molding tool E-1 having a cross-sectional shape as shown by a dashed-dotted line in FIG. Perform mold making and molding. Before the molded cable holder has completely cooled down, the second molding tool E-2 is moved in the direction of arrow _X1 in FIG. 3 and removed, and then the first molding tool E-1 is removed.

In the removal step of the mold tool after this molding, the first mold tool E-1 includes the stepped portion 22-1 of the cable holder,
22-2 exists, but since the molded cable holder is not completely cooled when the first molding tool E-1 is moved and removed, the elastic holding pieces 20-1, 20- 2 can be easily elastically moved so as to increase the mutual distance between them, and the first mold tool E-1 can be easily moved by the elastic holding piece 20.
-1, 20-2 can be extracted. In this way, two types of mold tools E-1 and E-
2 is combined to make a mold, and after molding, the manufacturing process simply moves the mold tools E-1 and E-2 in two directions, making the cable holder compact in the longitudinal direction with high precision quality. It can be manufactured extremely efficiently by holding it.

The cable holder of this invention is inserted into the board 10 as shown by the dashed line in FIG.
2-1 and 12-2 are inserted and fixed into mounting holes formed in the substrate 10. Base 11 for substrate 10
When inserting the insert pieces 12-1, 12-2
Due to the presence of the recesses 14-1 and 14-2, the insertion pieces 12-1 and 12-2 are elastically biased toward each other at right angles to the insertion direction, and at the position where they have passed through the mounting hole of the board 10, the insertion pieces 12-1 and 12-2 is located outside the edge of the mounting hole, and the base 11 is elastically fixed and held to the substrate 10.

Next, between the elastic holding pieces 20-1 and 20-2 from the top plate 15 side of the base 11, the elastic holding pieces 20-1 and 20-2 are elastically pushed outward from each other. Insert the cable C to be connected, and insert its end into the cable insertion holes 16-1 to 16-
