Background Technology

[0002] In the prior art, connectors typically include a housing and terminals disposed in sockets within the housing. To prevent the terminals from being pulled out of the housing, a locking spring is usually formed in the socket of the housing. This locking spring engages with the terminal to lock it in the socket. When it is necessary to remove the terminal, the locking spring must first be pushed to the unlocked position, separating it from the terminal. In the prior art, to prevent the terminals from being accidentally unlocked, a terminal position safety device is inserted into the housing. This device prevents the locking spring from being pushed to the unlocked position, thereby preventing the terminals from being accidentally unlocked.

[0003] In existing technology, in order to lock the terminal position safety element in a predetermined installation position, a locking protrusion needs to be formed on the terminal position safety element. This locking protrusion engages with a groove on the peripheral wall of the housing to lock the terminal position safety element in the predetermined installation position.
