BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a split type connector having a fitting detection function.

[0002]

2. Description of the Related Art In recent years, the connectors used for automobile wire harnesses have tended to have more and more poles. However, in such a multipole connector, if a male and female connector housing is attempted to be mated at one time, great mating force is required. Will be needed.
Conventionally, as a workaround, a so-called split type connector has been used in which one of the connector housings is divided into a plurality of pieces and the fitting force is reduced by sequentially fitting them into the mating connector housing. . On the other hand, particularly in an important circuit such as an airbag circuit, a short-circuit terminal or the like is used to detect whether or not the connector is properly fitted.

[0003]

However, if the split connector is used to detect the above-mentioned fitting, it is necessary to provide a short-circuit terminal for each split housing and perform the detection work for each of the split housings. However, there was a problem that increased the cost and complexity of the work, leading to high cost. The present invention was completed in view of the above circumstances, and an object of the present invention is to provide a connector that is of a split type in order to reduce the mating force, and yet realizes simplification of mating detection. And

[0004]

As a means for achieving the above object, the invention of claim 1 is provided with male and female connector housings, each of which is equipped with a group of terminal fittings. In a connector that is divided into two parts and can be fitted into the other connector housing, between the adjacent split housings, the pushing force of the split housing to be fitted later pushes the previous split housing into the normal position. It is characterized in that the auxiliary means is provided and the final split housing is provided with a fitting detection means for detecting whether or not the split housing is properly fitted.

According to a second aspect of the present invention, in the first aspect of the invention, a flexibly deformable lock piece is provided on a side surface of the front split housing adjacent to the rear split housing. When the split housings are fitted, the split housings are flexibly deformed while riding on the locking portions provided on the mating connector housings, and are restored and deformed when the split housings at the ends are properly fitted and engaged with the locking portions. It is characterized in that, while being stopped and being flexibly deformed by the riding operation, the subsequent split housing is configured to be capable of pressing and projecting into the fitting region thereof.

[0006]

[Action]

<Invention of Claim 1> When the split housings are sequentially fitted, even if the split housings are temporarily held in a semi-fitted state, the split housings are fitted while pushing the split housings into the proper positions. Are combined. Therefore, when the final split housings are mated, all the split housings before that are properly fitted, and if the fitted state of the final split housings is detected, the fitted states of all the split housings are detected. Can be detected at once.

<Invention of Claim 2> The above-mentioned split housing is fitted while the lock piece is mounted on the locking portion and flexibly deformed. If the former split housing is held in the half-fitted state, the lock piece projects into the fitting area of the latter split housing, so when the latter split housing is fitted, the lock piece is inserted through the lock piece. The former split housing is pushed to the normal position to be locked, and subsequently the fitting operation of the latter split housing is continued. Similarly, when the final split housings are mated, all previous split housings are properly mated, and if the final split housing mating state is detected, all split housings will be mated. The state can be detected at once.

[0008]

According to the present invention, since the fitting detecting means need only be provided in the final split housing, the number of parts can be reduced, the detecting operation can be simplified, and the cost can be reduced. There is an effect that can be done.
