Description

  The present invention relates to a wire harness clamp for fixing a wire harness having a main line and a branch line formed by branching from the main line to which a connector is attached to a fixing target.

  Conventionally, in order to fix a wire harness having a branch line B2 used for wiring of a vehicle or the like to an object to be fixed, an appropriate portion of the branch line B2 with respect to the trunk line T2 of the wire harness as shown in FIG. Was wound with slit tape 213. At this time, if the portion on the branch line B2 wound by the slit tape 213 is too close to the base end portion of the connector C2 attached to the distal end of the branch line B2, the degree of freedom of the branch line B2 becomes low, and the connector C2 There arises a problem that it is difficult to connect arbitrarily. For this reason, it is a common practice that the part where the branch line B2 is wound by the slit tape 213 is partly separated from the connector C2 attached to the end of the branch line B2.

  However, if the portion on the branch line B2 wound by the slit tape 213 is too far from the connector C2 attached to the end of the branch line B2, the degree of freedom at the end of the branch line B2 becomes too high, and the position of the connector C2 There was a problem that it was impossible to be sure. Further, in this case, not only is the position of the connector C2 not surely determined, but it is difficult to find the connector C2, and it is difficult to attach a protective material for protecting the wire harness to the wire harness. There is a problem of becoming. Further, the connector C2 at the tip of the branch line B2 may interfere with other parts, and noise may be generated.

  The present invention was created in view of the above problems, and while fixing the trunk line of the wire harness to a fixed object, while fixing the branch line branched from the trunk line while allowing flexibility, It is an object of the present invention to provide a wire harness clamp capable of detachably fixing a connector attached to the end of the branch line.

  In order to achieve the above object, a wire harness clamp according to the present invention is a wire harness for fixing a wire harness having a trunk line and a branch line branched from the trunk line and having a connector attached to the tip thereof to a fixed object. A clamp for supporting the main line, a locking part for locking the base to a fixed object, a branch fixing part for fixing the branch line to the base, and the connector on the base. It has a connector fixing part for fixing with respect to it.

  The clamp for wire harness according to the first embodiment of the present invention has a substantially plate-like base portion, a locking portion formed on one surface thereof, and a substantially S-shape in the normal direction from the other surface to the other surface. Two S-shaped portions facing each other are formed, and at the upper end of each S-shaped portion, there is a connector fixing portion for holding and fixing the connector, and these S-shaped portions are twisted to each other. By being hooked, a substantially annular branch line fixing part that surrounds the branch line by a part of the S-shaped part can be created.

  In the wire harness clamp of the second embodiment of the present invention, the base portion has a substantially plate shape, a locking portion is formed on one surface, and the other surface is in a normal direction from the other surface. A connector fixing portion and a branch wire fixing portion that extend and face each other are formed. The connector fixing portion has a connector locking portion that locks the connector at the tip thereof, and the branch wire fixing portion is connected to the connector fixing portion. It is characterized by surrounding the branch line in a substantially annular shape and fastening it so as to be fixed with respect to the base.

  According to the clamp for the wire harness of the present invention, the base fixing portion for fixing the trunk line to the fixing target is used to fix the branch wire while providing flexibility, and to fix the connector attached to the tip of the branch wire. By providing, the wire harness and the connector can be securely fixed, the fixing position of the connector can be clarified, workability can be improved, and abnormal noise can be prevented. Moreover, the slit tape which was conventionally used for fixing the branch line becomes unnecessary.

  Hereinafter, preferred embodiments of the present invention will be described in detail. The clamp for a wire harness according to the present invention is for fixing a wire harness having a relatively thick and long trunk line and a relatively narrow and short branch line branched from the trunk line and having a connector attached to the tip thereof to an object to be fixed. It is a clamp.

  The clamp for a wire harness has a base for fixing the wire harness to an object to be fixed while supporting the trunk line. The base is provided with a locking portion for locking the base to a fixed object. In addition, the base is provided with a branch line fixing part for fixing the branch line to the base. In this initial state, the branch line fixing part is not in a state of fixing the branch line, but in use, the branch line fixing part is deformed by a required operation and transformed into a fixed state, so that the branch line is provided with flexibility. It is comprised so that can be fixed to a base.

  Moreover, the clamp for wire harnesses has a connector fixing part for fixing a connector with respect to a base. This connector fixing part may be provided directly on the base, or may be provided indirectly on the base via the base line fixing part.
