Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric junction box, and more particularly, to an electric junction box having a cover mounted on a main body case of the electric junction box to restrict scattering of a wire harness.

[0002]

2. Description of the Related Art Various electric circuits and electronic parts are stored, and as a connection branch point of wirings such as a wire harness,
An electrical junction box is used.

FIG. 8 shows an example of this type of electric junction box. In FIG. 8, a plurality of connectors 52 are provided on a main body case 51 of the electric connection box 50. Each connector 52 has a wire harness 53 connected to each external device.
Is connected.

[0004] The wire harness 53 includes a main body case 5.
There is a risk that they are close to each other and interfere with other components or mounting and fixing members (for example, a vehicle body of a vehicle), or are rubbed against each other due to vibration of the mounting and fixing members to cause a short circuit.

Therefore, as shown in FIG. 8, there has been proposed an electric connection box 50 in which a cover 54 for restricting scattering of the wire harness 53 is mounted on the main body case 51. In such an electric junction box 50, the connection between the cover 54 and the main body case 51 is formed by bending a plurality of tips projecting above the main body case 51 into an L shape as shown in FIG. The locking member 55 is locked by a locking hole 56 provided in the cover 54.

[0006]

As a normal operation procedure, the cover 54 is attached to the main body case 51 after the wire harness 53 is connected to the connector 52. That is, the cover 54 is attached to the main body case 51 while holding down the wire harness 53.

However, the wiring harness 5
If the wire harness 53 has a strong rebound force when the wire 3 is pressed, the locking member 55 cannot be easily locked in the locking hole 56, and in some cases, a large force (for example, weight is applied). T) It was necessary to lock it forcibly. Therefore, the workability is very poor, and at the same time, the electric connection box 50 (the main body case 51 or the cover 54) may be damaged.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide an electric connection which can improve workability and can be easily mounted without being damaged. Is to provide boxes.
