Lockable electric connector
A lockable electric connector to be fitted and electrically connected to a socket provided on an outer face thereof with a rib extending in the insertion direction. The electric connector is provided with: a contact; a housing which has a fitting concave for receiving the socket, and which holds the contact such that a portion of the contact is exposed in the fitting concave; and a locking claw formed as projecting from the housing toward the upstream side in the socket insertion direction for holding the fitting state of the socket to the lockable electric connector. The locking claw has an engaging projection to be locked and engaged with an engaging portion of the socket, the engaging projection being formed at a position upstream with respect to the fitting concave in the socket insertion direction. The engaging projection has a guide groove for guiding the rib of the socket, the guide groove extending in the socket insertion direction.
1. A lockable electric connector adapted to be fitted and electrically connected to a socket provided on an outer face thereof with a rib extending in a socket insertion direction, comprising:
a contact in a form of a pin having a first pin portion and a second pin portion;
a housing having a fitting concave for receiving the socket, the housing formed to surround and contact the first pin portion in a manner to hold the contact in a stationary state in the housing with the second pin portion projecting into the fitting concave; and
a locking claw projecting from the housing toward an upstream side in the socket insertion direction for holding the socket in the fitting concave in a fixed state,
the locking claw having an engaging projection operative to be locked and engaged with an engaging portion of the socket, the engaging projection formed at a position upstream with respect to the fitting concave in the socket insertion direction,
the engaging projection having a guide groove for guiding the rib of the socket, the guide groove extending in the socket insertion direction.
2. A lockable electric connector according to claim 1 , wherein the engaging projection is arranged such that, when fitting the socket into the fitting concave, the socket tip is inserted into the fitting concave before the engaging portion of the socket comes in contact with the engaging projection.
3. A lockable electric connector according to any of claims 1 and 2 , wherein the guide groove passes through the engaging projection along a projecting direction of the engaging projection.
