DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for fixing a plurality of joint connectors, and more particularly, to a structure for connecting a plurality of joint connectors respectively connected to tips of a plurality of branch lines branched from a wire harness, and connecting to a vehicle side. It is fixed.

[0002]

2. Description of the Related Art In recent years, in a wire harness for an automobile, instead of connecting electric wires by splicing the electric wires to form a circuit,
2. Description of the Related Art A joint connector is connected to a branch line branched from a main line of a wire harness. In this case, since the joint connector connected to the branch line cannot be left hanging from the wire harness trunk, it must be fixed to the trunk or fixed to the vehicle.

When a joint connector is fixed to a wire harness trunk, as shown in FIG. 7, a joint connector 3 connected to the tip of a branch line 1 branched from the trunk of the wire harness W / H is connected to the trunk using a tape 4, respectively. It is wrapped around and fixed. On the other hand, when fixing to the vehicle side, a bracket is protruded from the vehicle side, and the joint connector is fixed to the bracket.

[0004]

However, with the increase in the number of electrical components, the use of joint connectors instead of eliminating splices has been increasing. However, there is a problem that it takes time and labor. In addition, when fixing to the vehicle side, a number of brackets must be protruded on the vehicle side, and this method also has a problem that the number of working steps is increased. Furthermore, since the branch connector is branched from the main line of the wire harness and the joint connector is attached at the same position or a close position, a plurality of joint connectors are fixed in close proximity. There is a disadvantage that it is difficult to perform and the workability is deteriorated.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to easily fix a plurality of joint connectors connected to a plurality of branch lines branched from the same position or a close position of a main line of a wire harness. It is intended to be.

[0006]

In order to achieve the above object, according to the present invention, a lock portion is provided on an outer surface of two joint connectors respectively connected to tips of two branch lines branched from a main line of a wire harness. On the other hand, a clamp for connecting and fixing these two joint connectors is provided, a locking piece for fixing the vehicle is protruded at the center of the board of the clamp, and the two joint connectors are provided on the extension portions on both sides of the board. Locked portions are provided which engage with the lock portions of the joint connectors to connect the two joint connectors via a clamp. Provided is a connection fixing structure for a plurality of joint connectors in which a locking piece is locked and locked in a locking hole on a vehicle side.

Further, according to the present invention, lock portions are provided on the outer surfaces of four joint connectors respectively connected to the tips of four branch lines branched from the trunk of the wire harness, and these four joint connectors are connected and fixed. A clamp is provided, and a substrate of the clamp is formed in a cross shape. A locking piece for fixing a vehicle is protruded at a central portion thereof, and the four joints are provided at each extension portion extending at an interval of 90 degrees from the central portion. Locked portions that engage with the lock portions of the connectors are provided, and these locked portions are respectively engaged with the lock portions of the joint connector to connect the four joint connectors via clamps. There is provided a connection and fixing structure for a plurality of joint connectors in which the locking pieces are locked and locked in locking holes on a vehicle side.

[0008]

In order to achieve the above connection fixing structure, first, a clamp is connected to one of a plurality of joint connectors respectively connected to branch lines branched from the wire harness. That is, the locking portion of the joint connector is engaged with the locked portion of the clamp and fixed. Then, the locked portion of the clamp is engaged with the lock portion of another joint connector and fixed. In this state, the plurality of joint connectors are connected to each other. Next, the locking piece of the clamp is inserted and fixed in the locking hole on the vehicle side, so that the plurality of joint connectors are securely fixed and held on the vehicle. In a state where a plurality of joint connectors are connected by a clamp, the wire harness becomes a straight line parallel to the trunk line, and when the joint connector does not hang from the trunk line, it is not always necessary to fix the joint connector to the vehicle side. It is possible to use a clamp having no side locking piece protruding.

Further, when the above-mentioned clamp is used, each extension of the board of the clamp is fitted along the guide rail of each joint connector, and the lock claw is inserted and locked by the lock hole. Connectors can be easily and reliably connected. In addition, since the locking piece is provided in the center, multiple joint connectors can be balanced,
Can be fixed to the vehicle side.
