Description of the Related Art For example, in a multi-pole connector having electrodes having several tens of poles, a split type connector is partially used for the purpose of preventing erroneous insertion of a terminal fitting into the connector. There is. This split connector is provided with a plurality of connector housings to which a small number of terminal fittings are respectively mounted, and these housings are inserted and locked in the same number of housing holes formed in a single frame. Also, the number of wires that can be pulled out from the housing is inevitably large, so run them all together in one direction, and attach a cover to the frame so that they cover them, for convenience of wire protection and handling. It has a designed structure. Then, the male and female split connectors are coupled with a coupling member such as a lever and a bolt, and the male and female connector housings are fitted and connected accordingly.

By the way, in the conventional split connector of this type, the structure of the portion where the connector housing is inserted and locked in the accommodation hole of the frame is disclosed in, for example, Japanese Utility Model Laid-Open No. 4-129477. After being inserted into the accommodation hole and abutting against the abutting portion, a retainer formed as a separate piece is attached to the frame so as to penetrate the inserted housing, and thereby the housing is irremovably accommodated. It was like this.

[0004]

That is, in the prior art, since the retainer of another piece is used for locking the connector housing, its manufacturing cost and management cost are separately required, and it is troublesome. Since an additional assembling process of the retainer is required, there is a drawback that the price is high as a whole. The present invention was completed in view of the above circumstances, and an object thereof is to provide a connector that can reduce the number of parts and reduce the cost.

[0005]

As a means for achieving the above object, the invention of claim 1 inserts and locks a connector housing in which a terminal fitting is mounted in a housing hole provided in the frame, and In a connector in which a cover covering the electric wire drawn out from the connector housing is attached to the connector, an abutting portion for abutting the front surface in the insertion direction of the connector housing is projected on the inner surface of the housing hole of the frame, and the cover is attached to the cover. The present invention is characterized in that a locking portion that locks on the rear surface in the insertion direction of the connector housing is provided.

According to a second aspect of the present invention, in the first aspect of the present invention, a pair of locking portions are provided so as to respectively lock to the corresponding two side edges of the rear surface of the connector housing.

[0007]

The operation of the invention of claim 1 is as follows. When the connector housing is inserted into the accommodation hole of the frame, the insertion is stopped when the front surface of the connector housing hits the abutting portion. When the cover is subsequently attached to the frame, the locking portion integrally provided on the cover locks to the rear surface of the housing, and the housing is irremovably accommodated in the accommodation hole. In the invention of claim 2, when the cover is attached after inserting the connector housing into the accommodation hole,
The housing is housed in the housing hole by locking the pair of locking portions to the corresponding two side edges of the rear surface of the housing.

[0008]

That is, according to the first aspect of the invention, since the locking portion for locking the connector housing is provided integrally with the cover, compared to the conventional case where a retainer of another piece is provided. As a result, the number of parts is reduced to reduce manufacturing costs and management costs, and the housing is automatically locked when the cover is attached, so that the locking process is unnecessary, so the overall cost is low. There is an effect that various connectors can be supplied. Further, according to the invention of claim 2, in addition to the above effect, the structure is such that the corresponding two side edges of the rear surface of the connector housing are locked by the pair of locking portions, so that the housing is well-balanced and more firmly engaged. There is a stopping effect.
