Abstract

PURPOSE:To lighten a molded cable for an automobile by forming a bent portion of each wire into flat and making a long diameter of the flat portion in about same level with a virtual line formed by the wire in front and rear of the bent portion so as to remove a protector. CONSTITUTION:A wire harness 1 is formed by aligning more than a wire 1', provided with some bent portions 2 according to the necessity and is bent in solid. The bent portion 2' is formed in flat. The bent portion 2' formed in flat is formed such that its long diameter is made about in same level with a face E virtually formed by wires 1a' and 1b' in front and rear of the bent portion 2'. Rigidity of the bent portion 2 of the wire harness 1 is, thus, improved by way of being formed in flat and hardening. Accordingly, three dimensional bent form of a molded cable is maintained and it is lightened without a protector.

On the other hand, regarding the protector, the original purpose of the protector is to protect the wire harness and prevent damage. However, although it is an auxiliary purpose, it is used for the bent portion of the wire harness, as described above, and has an important purpose in maintaining its shape. Conventionally, it has been used as an indispensable part for the bending part of a wire harness for the latter purpose. However, the bent portion of the wire harness of the present invention can maintain its bent shape even without a protector. Therefore, there is no need to use the protector at the bend unless the protector is used to prevent damage.

FIG. 5 shows another embodiment in which the long axis of the bent portion 2' is formed at an angle of 45° with the imaginary plane E formed by the single wire before and after the bent portion. When formed in this manner, the width W' of the bent portion 2 can be made approximately the same as the width W of the straight portion shown in FIG. 3(a). Moreover, it has rigidity against both the stress in the direction of the virtual plane E and the stress in the direction orthogonal to the virtual plane E, making it easier to maintain the shape of the bent portion 2.
