Description

  The present invention relates to a connector for equipment.

  For example, a device described in Patent Document 1 is known as a device connector to be attached to a case such as an automatic transmission of an automobile. Since this equipment connector is fitted into a mounting hole provided in a case of an automatic transmission filled with lubricating oil, for example, lubricating oil is contained in the equipment connector at the case mounting portion fitted into the mounting hole. A rubber plug is attached to prevent intrusion.

  By the way, when the number of poles of the terminal mounted on the device connector increases, the connector fitting portion that can be fitted with the counterpart connector becomes larger, while the case fitting portion that can be fitted into the mounting hole provided in the case is Since it is the same as before, the connector fitting portion is relatively larger than the case mounting portion. If the connector fitting portion is larger than the case attachment portion, a resin lance to be molded cannot be formed in the connector fitting portion by opening the mold on the connector fitting portion side and the case attachment portion side. Therefore, for example, a means is used in which a terminal holder that holds a terminal fitting separate from the connector housing is provided and the terminal holder is attached to the connector housing.

  In a device connector having such a separate terminal holder, the terminal fitting is attached by the following procedure, for example, in order to attach the terminal fitting to the connector housing. First, an electric wire is passed through the rubber plug and the connector housing, and a terminal fitting is crimped to the electric wire. Next, the terminal fitting connected to the electric wire is press-fitted and fixed to the terminal holder using a jig or the like, and the terminal holder is mounted in the connector housing.

However, according to the assembly procedure as described above, it is necessary to pass the electric wire first through the rubber plug and the connector housing. Further, after fixing the terminal fitting to the terminal holder, the number of assembling steps for fixing the terminal fitting to the connector housing is increased, such as fixing the terminal holder to the connector housing. Therefore, it is conceivable to form the resin lance in the connector fitting portion when the connector housing is configured separately from the connector fitting portion and the case mounting portion and the connector fitting portion is formed.
However, according to such a structure, in addition to the rubber plug attached to the case mounting portion, a seal member that seals between the connector fitting portion and the case mounting portion is required, which increases the number of parts and the number of assembly steps. .

  The present invention has been completed based on the above circumstances, and an object thereof is to improve the workability of assembling the terminal fitting to the connector housing without increasing the number of parts and the number of assembling steps.

The present invention as means for achieving the above object, a connector device to be mounted in a mounting hole provided in the case of the device, a tubular shape that is open in the longitudinal direction, the other party to the front opening A first housing provided with a connector fitting portion that can be fitted with a connector, and a terminal housing that is located between the front opening and the rear opening in the first housing and accommodates a terminal fitting connected to an electric wire And a case mounting portion that is fitted and mounted in the mounting hole, allows the electric wire drawn out from the terminal accommodating portion to be inserted therein, and is fitted into the rear opening of the first housing. a tubular second housing that is molded by mold opening the mold for molding of the first housing, a lance for retaining the terminal fitting in said terminal accommodating portion, the said first housing first By sandwiching between the first housing and the second housing by being sandwiched between the first housing and the second housing, the electric wire and the first housing A rubber plug that seals between the inner peripheral wall and the inner peripheral wall of the second housing in a liquid-tight manner, and a plurality of outer peripheral lips are provided on the outer periphery of the rubber plug.

Two flanges projecting over the entire circumference are provided on the outer peripheral surface of the rubber stopper between the outer peripheral lip on the front side and the outer peripheral lip on the rear side. Before Flange has characterized in that the longitudinal entire both surfaces are held between the second housing and the first housing.

According to the device connector having such a configuration, there is no need to hold the terminal fitting using the terminal holder as in the conventional device connector, and a lance is formed in the terminal housing portion when the first housing is formed. The terminal fitting can be held by this lance. As a result, the terminal fitting can be assembled to the connector housing without increasing the number of parts and the number of assembling steps as compared with the conventional device connector in which the terminal holder fitted with the terminal fitting is attached to the connector housing. .
Further, since the first and second housings are divided, water or the like may enter from between the first housing and the second housing. And between the electric wire and both housings can be sealed with a single rubber stopper. Therefore, the workability of assembling the terminal fitting to the connector housing can be improved.

Further , since the flange is sandwiched between both housings, it can serve as a face seal. Thereby, it is possible to lengthen the path from the interface between the first housing and the second housing to the inside of both housings and the path connecting the inside of the first housing and the inside of the second housing on the outer peripheral surface of the rubber plug. it can. Accordingly, it is possible to prevent water from entering the both housings from the outside and oil from entering the first housing from the second housing. In addition, since the rubber plug is sandwiched and held between the first housing and the second housing, the rubber plug can be stably held without separately providing a holding member such as a back retainer for holding the rubber plug. be able to.

  According to the present invention, it is possible to improve the workability of assembling the terminal fitting to the connector housing without increasing the number of parts and the number of assembly steps.
