[0006] Furthermore, since the connector connecting portions related to the connection of the wire harnesses are scattered in various places in the vehicle, the work of connecting the connectors is complicated, and the work space must be secured. become.

Therefore, the inventor of the present application pays attention to the electric connection box, and as shown in FIG. 17, rails (not shown) are formed on the side surfaces of the main body 1 constituting the electric connection box to form the wire harnesses 2 and 3. It has been conceived that the connectors 4, 5, and 6 are slid and fixed, and the connectors 9, 10, and 11 of the wire harnesses 7 and 8 are connected to the connectors 4, 5, and 6, respectively.

When the undercover 12 is mounted and the wire harnesses 2 and 3 and the wire harnesses 7 and 8 are led out of the undercover 12 through the grommets 13 to 15, the connectors 4, 5 and 6 are connected. , Connectors 9, 10 and 11 are housed in the under cover 12, eliminating the need to provide a waterproof structure to the connector itself, and also concentrating the connector connection portion on the electrical connection box, It was thought that the workability could be improved and a work space could be secured by passing through through.

Further, the inventor of the present application did not limit to the above, and did not forget to further search for a better one. Then, some points to be improved were found, and it was determined that it was necessary to solve those points.

That is, the above-mentioned improvements are as follows. When the main body 1 and the under cover 12 are mounted in advance, it is not easy to slide and fix the connectors 4, 5, and 6, and conversely, the connectors 4, 5, and 6 are attached to the main body 1.
When the under cover 12 is attached after fixing the wires 5 and 6, the wiring harnesses 2 and 3 hanging downward (refer to the lower side in the figure when viewed properly) and the wires led out from the lower portion of the main body 1. It becomes very difficult to manage a harness (not shown), which affects workability. If the wiring harnesses 7 and 8 are covered on the electric component insertion surface of the main body 1 when the wiring harnesses 7 and 8 are routed, the maintainability of the electric connection box itself is affected. Will be.

On the other hand, if the wire harnesses 2 and 3 hang down, if water enters from the grommet 13 or the like, a capillary phenomenon is likely to occur, affecting the connector connection portion and the main body 1 and the like. Will be lost.

On the other hand, since the connector connection portion is disposed on the side surface of the main body 1, unnecessary space may be created for members, devices, and the like near the electric connection box.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and has been made to eliminate the waterproof structure of the waterproof connector by taking in the connector connection portion, thereby making the electrical connection box and the wire harness which can be made non-waterproof. It is an object to provide a routing method.

For example, it is not necessary to provide a waterproof structure to the LIF connector 32 and the LIF connector 47, and the number of components can be reduced and the assembling property can be improved. In addition, since the connector connection portion is concentrated on the electric connection box 21, workability related to the connector connection is also good. Therefore, by taking in the connector connection portion, the waterproof structure in the waterproof connector can be abolished, and an electric junction box which can be made non-waterproof can be provided. The same effect can be obtained as a wiring harness wiring method.

In addition, it goes without saying that the present invention can be variously modified within the scope of the present invention.

[0072]

As described above, according to the first aspect of the present invention, the electric connection box is provided in the vehicle with the main body, and a plurality of electric connection boxes are routed in the vehicle. In addition, a connector box for interconnecting a wire harness having a connector at a terminal and housing a connector connection portion of one and the other connectors in a watertight manner is detachably attached to the main body. As described above, since the connector connection portion is stored in a watertight manner in the connector box detachably mounted on the main body, it is not necessary to provide a waterproof structure to either one of the connectors.
This can contribute to a reduction in the number of parts and an improvement in assemblability. Further, since the connector connection portion is concentrated on the electric connection box, the workability related to the connector connection is also good. Furthermore, since the connector box is detachable from the main body, a connector box in which the connector connection portion is stored in advance can be manufactured in a separate process from the main body. It is also possible to mount the unit and the connector box. Therefore,
By taking in the connector connection portion, the waterproof structure in the waterproof connector is abolished, and an effect is obtained that an electric connection box that can be made non-waterproof can be provided.

According to the second aspect of the present invention, the connector box has the slit for inserting the wire harness, and the harness protector for closing the opening after the insertion of the wire harness is attached to the slit. Therefore, it is not necessary to perform a complicated operation such as inserting a wire harness into a grommet with respect to waterproofing of a connector connection portion. Therefore, in addition to the above, there is an effect that the workability can be improved.

According to the third aspect of the present invention, since the slit and the harness protector are formed with the flange portion which is in close contact with the outer periphery of the wire harness, the deflection of the wire harness can of course be suppressed. That is, the area in close contact with the wire harness is increased, and the waterproof function of the connector box is improved. Therefore, there is an effect that the reliability of the connector box can be improved.

According to the fourth aspect of the present invention, one of the connector housings of the one and the other is configured to be fixed to the connector box, thereby facilitating the connector connection. As a matter of course, the stability of the connector connection portion in the connector box is improved. If the connector connection portion is stabilized, generation of abnormal noise and abrasion due to, for example, vibration while the vehicle is running will not occur. Therefore, there is an effect that workability and reliability can be improved.

According to the fifth aspect of the present invention, the one and the other connectors are LIF connectors for which fitting is promoted by operating the LIF lever, and when the LIF connector is incompletely fitted, the Since the lever is configured to be in contact with the main body, the connector connection can be made with a small force, and the incomplete fitting of the connector connection portion can be detected and prevented. Therefore, there is an effect that workability and reliability can be improved.

According to the sixth aspect of the present invention, L
The arrangement of the initial state before the operation of the IF lever is determined by:
Since the mounting direction of the main body and the connector box is substantially parallel to the mounting direction, the mounting of the main body and the connector box is attempted when the LIF lever is incompletely mounted in the initial state. Also, the LIF lever cannot be rotated due to the arrangement, and as a result, it is possible to reliably detect the incomplete fitting of the connector connection portion. Therefore, there is an effect that the reliability can be further improved.

According to the seventh aspect of the present invention, a plurality of electric components are inserted into the main body, and the connector box is arranged on a surface opposite to the insertion surface for the plurality of electric components. As a result, the wire harness from the connector connection portion stored in the connector box does not cover the insertion surface of the main body. Further, there is no need to arrange the wiring harness from the connector connection portion so as to hang down in the connector box. Further, since the connector box is stacked on the main body, no unnecessary space is created for members, devices, and the like near the electric connection box. Therefore, there is an effect that the maintainability and the space efficiency can be improved.

According to the present invention described in claim 8, the method of arranging a wire harness is a method of arranging a plurality of wires in a vehicle and having a connector at a terminal. The connector connecting portions of the one and the other connectors, which are related to the interconnection of the wire harness, are housed in a watertight manner in a connector box detachably attached to a main body of an electric connection box mounted in the vehicle. It has become. As described above, since the connector connection portion is stored in a watertight manner in the connector box detachably mounted on the main body, it is not necessary to provide a waterproof structure to either one of the connectors. This can contribute to a reduction in the number of parts and an improvement in assemblability. Further, since the connector connection portion is concentrated on the electric connection box, the workability related to the connector connection is also good. Furthermore, since the connector box is detachable from the main body, a connector box in which the connector connection portion is stored in advance can be manufactured in a separate process from the main body. It is also possible to mount the unit and the connector box. Therefore, there is an effect that the waterproof structure of the waterproof connector is abolished by taking in the connector connection portion, and a wiring harness routing method that enables non-waterproofing can be provided.
