Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric wire holding clamp used for holding an electric wire in a wire harness manufacturing process or the like.

[0002]

2. Description of the Related Art Conventionally, in order to fix an electric wire in a process of manufacturing a wire harness which constitutes electric wiring of a vehicle, particularly a flat wire harness, for example, as shown in FIG. It is also conceivable to use the disclosed protector P as a wire holding clamp.

However, the protector P is the substrate a.
And a lid plate c connected from the substrate a via a flexible hinge portion b. By closing the lid plate c with respect to the substrate a, an electric wire is gripped between the substrate a and the lid plate c. I am trying to do it. However, since there is no special mechanism for holding the electric wire, the electric wire may come off between the substrate a and the cover plate c, which may cause an obstacle such as interruption of the wiring process or generation of defective products. .

Therefore, as shown in FIG. 23, a clamp K is provided in which a plurality of electric wire holding members d are arranged side by side on a substrate a to hold electric wires between the electric wire holding members d.
Is also considered. The electric wire holding member d includes a roof-shaped introduction part f at the free end of the pillar body part e, and inserts the electric wire w between the pillar body parts e through a gap between the introduction parts f to form the pillar body part e and the introduction part f. The electric wire w is held between them.

However, the electric wire holding member d of the clamp K must be formed with a steep roof-like slope of the introduction portion f in order to facilitate the insertion of the electric wire w, and as a result, the pillar portion e. It is necessary to increase the height of the clamp K, which increases the thickness (height) of the entire clamp K, which makes it difficult to reduce the thickness of the entire wire harness.

1 is a perspective view showing an electric wire holding clamp A according to an embodiment of the present invention in an open state, and FIG. 2 is a side view thereof. The electric wire holding clamp A is integrally formed by molding a synthetic resin material.
And a lid plate 3 which is openably and closably provided from one side edge 1a of the substrate 1 via a flexible hinge portion 2.

A plurality of electric wire holding members 4 are erected on the inner surface 1b of the substrate 1, and fixing claws 5 are protruded on the outer surface 1c. A lock member 6 having a lock hole 6a is provided on the side edge 3a of the lid plate 3 and is engaged with a lock claw 7 formed on the other side edge 1d of the substrate 1, so that the substrate 1 and the lid plate 3
It can be fixed in the closed state.

The wire holding member 4 has a roof-shaped introduction portion 10 formed at the upper end of a column portion 9 having a support leg 8 that can bend and stretch. As shown in FIG. 3, the support leg 8 that supports the columnar portion 9 includes two support pieces 8 a, 8 that are erected on the inner surface 1 a of the substrate 1.
a'and two connecting pieces 8b connected to the lower end of the column body portion 9,
8b '. Then, the connecting pieces 8b, 8
Support pieces 8a and 8a 'are joined to each other at an intermediate portion of b'to form a thin plate in a rhombic shape.

When the introduction portion 10 is pressed from above toward the support leg 8, it is composed of the support pieces 8a and 8a 'and the connecting pieces 8b and 8b' of the support leg 8 due to the elasticity of the synthetic resin material. Since the diamond shape is flattened, the height of the wire holding member 4, that is, the height from the substrate 1 to the top end 10a of the introduction portion 10 is reduced. On the other hand, when the pressing force is released, the supporting leg 8 returns to the original rhombus due to the restoring force of the synthetic resin material, and the height of the wire holding member 4 is also restored. As described above, the support leg 8 is formed into a rhombic shape so that it can be bent and stretched.
