Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention connects a connector fixed to one electric unit and a connector provided at the end of a wire harness and arranged on the other electric unit side, and supports the wire harness. It is related to the structure.

[0002]

2. Description of the Related Art Generally, a connector is used for electrical connection between electric units, for example, electrical connection between a vehicle dashboard and an instrument panel, electrical connection between an instrument panel and an instrument, and the like. There is. That is, when there are electric units to be connected to each other, a connector is provided for each of them, and both electric units are connected and both connectors are connected to each other to make an electric connection.

As a method of connecting both the above-mentioned connectors, for example, the first connector is fixed to one electric unit in advance and the second connector is fixed to the other electric unit so that both electric units are connected to each other. The fixing position of each connector with respect to each electric unit is set so that the housings of both connectors fit together when the connectors are inserted.

However, in such a method, if there is any error in the mounting position of the connector with respect to each electric unit, there is a possibility that the connectors cannot be connected to each other. Further, even if the connector is attached to the electric unit at a correct position, it is very difficult to actually connect the housings of both connectors to each other while connecting the electric units.

Therefore, the applicant of the present invention temporarily fixes the first connector to one of the electric units connected to each other, and temporarily disengages the second connector from the holder attached to the other electric unit. Providing fastening means for locking and fastening the housings of both connectors,
After connecting the both electric units, by fastening the housings of the both connectors by the fastening means, the second connector is detached from the holder and connected to the first connector, thereby connecting the connectors. A structure which can be easily and surely proposed has already been proposed (for example, Japanese Patent Application No. 7-321770).

[0006]

By the way, for example, while fixing the first connector to one electric unit (for example, instrument), the first connector of the end of the wire harness arranged on the other electric unit (for example, instrument panel) side is fixed. When two connectors are provided and both electric units are connected and both connectors are connected, a separate measure against vibration of the electric wire bundle connected to the second connector is required.

That is, as described above, when the second connector is temporarily locked to the holder in advance and the second connector is detached from the holder and connected to the first connector by the fastening means, The electric wire bundle connected to the two connectors is loosened to some extent before the connector is connected and is in an extended state after the connector is connected. Even in this state, the electric wire bundle is free between the trunk and the second connector. Therefore, there is a problem that vibration is likely to occur, which may cause wire breakage and wear, and abnormal noise. In order to suppress such vibration of the electric wire bundle, it is necessary to separately provide a means for restraining the electric wire bundle.

Further, in the case of the structure as described above, the holder is necessary for temporarily locking the second connector before connecting the connector, but becomes unnecessary after connecting the connector, and the holder is effective. There is still room for improvement in terms of usage.

In view of the above circumstances, the present invention effectively utilizes a holder for temporarily locking the connector to hold the wire harness after the connector is connected, and to prevent vibration of the wire harness and generation of abnormal noise. An object is to provide a connector connecting portion structure that can be suppressed.

[0010]

The connector connecting structure of the present invention comprises a first connector fixed to one electric unit of electric units connected to each other, and a second connector provided at the end of the wire harness. And a holder attached to the other electric unit to temporarily lock the second connector, and a fastening means to fasten the housings of the first and second connectors. In a structure in which the second connector is pulled out from the holder and fitted into the first connector as the housings of the both connectors are fastened by the fastening means, the holder is laterally disposed to the second connector placement location. And a wire holding portion that is displaceable toward the inside of the holder is provided at the second position.
When the connector is temporarily locked in the holder, the displacement is blocked, and when the second connector is pulled out from the holder, the displacement is allowed and is biased by the biasing means. The electric wire bundle connected to the connector is displaced so as to be restrained.

According to this structure, the second connector is detached from the holder and fitted into the first connector by connecting the two electric units and fastening them by the fastening means. Positional deviation between connectors can be easily adjusted. Then, while both connectors are connected in this way, in the holder after the second connector is detached, the wire holding portion is displaced inward,
Vibration of the wire bundle is suppressed by restraining the wire bundle located in the holder in series with the connector.

As an example of a concrete structure of the electric wire holding portion and the like in the present invention, a pair or a plurality of pairs of arm members which also serve as the electric wire holding portion and the temporary locking portion are arranged in the holder. The member has an elastic piece as a biasing means whose base end side is fixed to the wall surface of the holder and whose tip end side can swing inward of the holder, and which is provided at the tip end of this elastic piece and engages with the second connector. When the second connector is pulled out from the holder, the arm member is disengaged from the second connector, and the distal end of the arm member swings inward by the biasing force of the elastic piece. It is configured to hold a bundle.

With this configuration, when the second connector is accommodated in the holder, the arm member temporarily locks the second connector, and when the second connector is pulled out from the holder, the second connector is pulled out. The arm member that has been detached from the connector and left in the holder serves to restrain the bundle of electric wires of the second connector and suppress the vibration thereof.

As another example of the specific structure of the electric wire holding portion and the like, the holder is a wall portion which constitutes the electric wire holding portion and is arranged so as to face each other across the second connector arrangement position. , And a frame portion connecting these wall portions,
A deformable portion that can be bent and deformed so as to shorten the frame portion is provided in an intermediate portion of the frame portion, and a biasing portion that biases the deformable portion when the second connector is pulled out from the holder is provided. Biasing means are provided on the holder.

With this structure, when the second connector is pulled out from the holder, the holder is deformed so as to be compressed by the bending of the deformable portion, whereby the wall portion is displaced inward, The electric wire bundle connected to the second connector is constrained.

As the biasing means, for example, a spring member is attached to the frame portion. Alternatively, a portion is provided inside the holder that moves forward by a certain amount when the second connector is pulled out from the holder, and a spring body is provided between this portion and the deformable portion as a biasing means. To be

As still another example of the specific structure of the electric wire holding portion and the like, a wall portion constituting the electric wire holding portion in which the holder is arranged so as to face each other across the second connector arrangement position. And a frame portion that connects these wall portions to each other so as to be relatively displaceable in a direction in which they approach each other, and a biasing means that biases both wall portions in a direction in which they approach each other, and the second connector is a holder. When the second connector is pulled out from the holder while being temporarily locked in the holder, a member that changes to a state in which the relative displacement of the both walls is allowed when the second connector is pulled out from the holder It is provided.

With this configuration, when the second connector is pulled out from the holder, the two wall portions are relatively displaced in the direction in which they approach each other, thereby restraining the electric wire bundle connected to the second connector.
