The present disclosure discloses a plug connector including an insulating housing, a number of plug terminals and a cable. The insulating housing includes a width direction extending along a left-and-right direction. The plug terminals are retained by the insulating housing and arranged in two rows in the width direction of the insulative housing. The plug terminals of each row are arranged in an upper-and-lower direction and spaced away from each other in the upper-and-lower direction. Each plug terminal extends along a front-and-back direction. The cable includes a number of core wires correspondingly and electrically connected with the plug terminals. A connector assembly including the plug connector and the mated socket connector is also disclosed in the present disclosure.

The present disclosure discloses a socket connector including an insulating base and a number of socket terminals. The insulating base includes an outer plastic frame defining a receiving channel and an inner plastic block received in the receiving channel. The inner plastic block includes two sidewalls opposite to each other in a left-and-right direction. The socket terminals are arranged in two rows by positioning symmetrically and respectively on the two sidewalls of the inner plastic block. The socket terminals of each row are arranged in an upper-and-lower direction and spaced away from each other in the upper-and-lower direction. Each socket terminal extends along a front-and-back direction perpendicular to both the left-and-right direction and the upper-and-lower direction. A connector assembly including the socket connector and the mated plug connector is also disclosed in the present disclosure.

A connector includes a housing which allows for insertion and fitting into a mating connector in an insertion direction perpendicular to a height direction and to a width direction, and a regular fitting detecting member. The regular fitting detecting member is supported on an outer wall surface of the housing so as to be slidable in the insertion direction to a non-detection position and a detection position. The regular fitting detecting member includes a base portion which has a detecting portion which allows for detecting regular fitting at the detection position, and an elastic piece and a pair of guide pieces which extend in the insertion direction from the base portion. The guide pieces allow for guiding sliding of the regular fitting detecting member by engagement with the housing. The elastic piece allows for the regular fitting detecting member to move to the detection position by being elastically deformed in the width direction. A lower surface of the elastic piece and lower surfaces of the guide pieces are disposed in a manner that shifts the position in the height direction.

A secondary securing means for locking an electrical plug connection of a first electrical plug connector and a mating plug connector includes a securing element and a plug-in prevention means. By a closing movement, the securing element can be moved from a preliminary latching position into a locking position in which the securing element mechanically secures the plugged plug connection. The securing element is operatively connected to the plugging prevention means in such a way that, during the closing movement of the securing element, the plug-in prevention means can be moved from a home position in which the plugging prevention means blocks a complete insertion of the mating plug connector into the first plug connector, to a clearing position in which the plug-in prevention means clears the displacement path between the mating plug connector and the first plug connector complete insertion of the mating plug connector into the first plug connector The plug-in prevention means moving from the home position into the clearing position by rotation about an axis of rotation or along a support element.

Disclosed is a device comprises: a moving block configured to have an inner space open toward one side, and to be capable of moving in forward direction toward a holder, formed on a connector jig, and in backward direction; a matching box, movably mounted in the moving block to be movable, of which shape is such that its movement in the forward direction is blocked by a part of a TPA connector seated in the holder if the part protrudes from the connector surface; and a contact switch configured to change its electrical state when the matching box moves, relative to the moving block, at a predetermined interval in the backward direction, wherein the moving block is configured to move further in the forward direction by at least the predetermined interval even in a state in which the matching box cannot move in the first direction.

A connector includes a housing and a release button. The housing defines a recess for receiving a latch member of a receptacle. The release button is operable to cause displacement of the latch member from the recess and has a surface that aligns with a surface portion of the housing when disconnected from the receptacle. The surface of the release button protrudes from the surface portion of the housing when the connector is connected to the receptacle to provide a visual indication that the connector is connected to the receptacle.

A connector includes a first housing, a second housing configured to be fitted to the first housing; a rotation member rotatably supported on the first housing; a lock arm including a lock part configured to lock with a lockable part of the first housing in a fitting completion position, an operation section configured to release the lock arm from a locked state, and a fulcrum part connected to an outer peripheral surface of the rotation member at a position between the lock part and the operation section, and configured to swing around the fulcrum part and to lock or release the lock arm by elastic deformation thereof; and a fitting detection member configured to detect a fitted state of the first housing and the second housing while being assembled to the rotation member and when moving in a locking direction from a temporally lock position to a fitting confirmation position.
