Disclosed is a waterproof connector which is capable of controlling the inserting posture of the terminal members with respect to the connector housing in the earlier stages of terminal insertion. The waterproof connector includes: a plurality of terminal members having inserting posture controlling protrusions; and a connector housing having a plurality of terminal accommodating chambers for accommodating the terminal members. A waterproof plug which has a plurality of sealing insertion holes corresponding to the terminal accommodating chambers is fitted into the rear section of the connector housing, and a waterproof plug retaining cover is mounted on the rear end section of the housing. The waterproof plug retaining cover has terminal insertion holes corresponding to the sealing insertion holes, and the terminal insertion holes have inserting posture controlling recesses allowing passage of the inserting posture controlling protrusions formed on the terminal members.

DETAILED DESCRIPTION It is accordingly an object of this invention to provide a waterproof connector in which any error in the inserting posture of the terminal members with respect to the terminal accommodating chambers of the waterproof connector can be detected in the earlier stages of insertion.
To achieve the above object, in accordance with this invention, there is provided a waterproof connector comprising: a plurality of terminal members having inserting posture controlling protrusions; a connector housing having a plurality of terminal accommodating chambers for accommodating the terminal members; and a waterproof plug which has a plurality of sealing insertion holes corresponding to the terminal accommodating chambers and which is fitted into the rear section of the connector housing, wherein a waterproof plug retaining cover is mounted on the rear end section of the housing, and wherein insertion holes corresponding to the sealing insertion holes are formed in the waterproof plug retaining cover, the insertion holes having inserting posture controlling recesses allowing passage of the inserting posture controlling protrusions formed on the terminal members.
In accordance with the present invention, the terminal members are inserted into the terminal accommodating chambers through the sealing insertion holes of the waterproof plug when the inserting posture controlling protrusions of the terminal members are aligned with the inserting posture controlling recesses of the insertion holes formed in the waterproof plug retaining cover.
Thus, there is no fear of the terminal members being erroneously inserted into the insertion holes of the waterproof plug, thereby improving the efficiency of the terminal member inserting operation.
In a preferred embodiment of the present invention, the walls constituting the terminal accommodating chambers have grooves into which the inserting posture controlling protrusions formed on the terminal members are allowed to penetrate, thereby stabilizing the posture of the terminal members inserted into the terminal accommodating chambers
