[0002] In the prior art, a connector generally includes a housing, a terminal disposed in the housing, and a locking rod rotatably mounted on the housing. The locking rod is capable of rotating between a pre-locking position and a final locking position. The locking rod is used to drive the mating housing of the mating connector to move from a pre-installed position to a final installation position mating with the housing. When the locking rod rotates from the pre-locking position to the final locking position, the locking rod is capable of driving the mating housing to move from the pre-installed position to the final installation position. In the prior art, in order to keep the locking rod in the pre-locking position, two retaining structures need to be provided on the housing and the locking rod, one retaining structure preventing the locking rod from rotating forward from the pre-locking position, and the other retaining structure preventing the locking rod from rotating backward from the pre-locking position. This results in a complex structure of the locking rod and the housing. Utility Model Content
