Description

Technical Field

[0001] The utility model relates to a connector housing component and a connector comprising the connector housing component. Background Art

[0002] In the prior art, the connector generally includes a housing and a terminal. A socket for inserting the terminal is formed in the housing, and the socket has an axially opposite mating port and a mounting port. The terminal is inserted into the socket of the housing from the mounting port of the socket. The mating terminal that matches the terminal is inserted from the mating port of the socket and matches with the terminal. The terminal generally has a locking spring sheet that abuts against the locking step in the socket to lock the terminal in the socket of the housing. When the terminal needs to be pulled out of the socket, it is necessary to use an unlocking tool to push the locking spring sheet of the terminal to an unlocking position separated from the locking step. In the prior art, the unlocking tool is generally inserted from the mating port of the socket. Therefore, in order to facilitate the insertion of the unlocking tool and leave enough space for unlocking, the diameter of the mating port of the socket is generally much larger than the diameter of the mating terminal. This causes the mating terminal to be easily inserted into the mating portion of the terminal and the inner wall of the socket by mistake, rather than being inserted into the mating portion of the terminal.
