A lever-type connector includes first and second connectors, and a lever member. The first connector includes a cam pin. The second connector is connected to a cable and is fitted to the first connector. The lever member includes a body and an operating part, where a cam groove into which the cam pin is inserted is formed in the body, and the operating part is contiguous to the body and is used for performing a rotating operation. The lever member is rotatably attached to the second connector and causes the first connector and the second connector to be fitted together by rotating from an initial position to a final fitting position. When the lever member is rotated, a tip of the operating part moves through a space (situated on the cable side with respect to a front face of the second connector) from which the cable is led out.

A wire cover (70) is arranged to cover a rear surface of a housing (10) and includes a back plate (73) in a rear part. A pull-out port (77) for wires (30) is provided in an end part of the back plate (73) and an opening (74) is provided separately from the pull-out port (77). A U-shaped lever (90) is arranged to straddle the back plate (73) and connects the housing (10) and a mating housing at a connection position by being rotated with an operating portion (91) gripped. The operating portion (91) of the lever (90) enters the opening (74) at the connection position and is arranged in contact with or in proximity to an edge of the opening (74).

An electronic module for an I/O modular system comprises a housing, a plug-in connection for the coupling to a connection of the I/O modular system, and at least one locking lever which has an actuating end arranged on the side turned away from the plug-in connection, and a locking portion. The locking lever has at least one light-conducting portion. A light source is associated with the locking lever. A light exit face is provided in the region of the actuating end of the locking lever.

In an open position, a power-supply terminal and a detection terminal are not connected to a mating power-supply terminal and a mating detection terminal, respectively. In a predetermined position, the power-supply terminal is connected to the mating power-supply terminal while the detection terminal is not connected to the mating detection terminal. In a closed position, the power-supply terminal and the detection terminal are connected to the mating power-supply terminal and the mating detection terminal, respectively. When the connector is turned toward the predetermined position from the closed position, a first regulating portion regulates a first regulated portion to prevent the connector from reaching the predetermined position. When the connector is turned toward the predetermined position after the regulation is released, a second regulating portion regulates a second regulated portion to prevent the connector from being turned toward the open position beyond the predetermined position.

An assembly for attaching and detaching an electronics module from a base includes a feedback assembly that provides an operator with tactile feedback on the relative positioning of the module with the base during attachment or detachment of the module to or from the base. The feedback assembly includes cams on the electronics module and a follower attached to an end of a spring arm on the base. The spring arm forms a portion of a wall that guides movement of the module along the base during attachment or detachment of the module.

A wire cover (70) is arranged to cover a rear surface of a mat seal cover (50) and includes a lock (78) to be locked to a lock receiving portion (27) of a housing (10). The lock receiving portion (27) is arranged at a position corresponding to a lever (90) covering an outer surface side of a peripheral wall (24) of an accommodating recess (23). The lock (78) is locked to the lock receiving portion (27) from an inner surface side of the peripheral wall (24) of the accommodating recess (23). The mat seal cover (50) has an assembling detection surface (55) with which the lock (78) moving toward the lock receiving portion (27) comes into contact when the mat seal cover (50) is in a semi-assembled state without being locked to the housing (10).

A lever-type connector (A) includes a connector body (10). A lever (30) has a base end (32) rotatably supported on the connector body (10) and a rotating portion (34) for rotational operation is formed on a tip (33) of the lever (30). A finger contact surface (59) is disposed on an outer surface (58) of the rotating portion (34) and is configured to receive contact of a finger during a rotational operation. A resilient lock (51) is formed on the connector body (10) and is configured to lock the lever (30) in a rotation restricted state. Unlocking portions (53) are formed on the resilient lock (51) and are configured to press the resilient lock (51) in a direction separating from the lever (30). The unlocking portions (30) are exposed on the outer surface (58) of the lever (30) with the resilient lock (51) and the lever (30) locked together.

A connector includes a first housing, a second housing, a mate assist slider, and a cam gear. The first-housing has a first outer surface. The second housing is configured to mate with the first housing, and the second housing includes a pin extending from a second outer surface. The connector also includes a mate assist slider moveable from an unmated position to a mated position. The connector also includes a cam gear mounted to the first outer surface. The cam gear moves in response to a movement of the mate-assist-slider from the unmated position to the mated position. The cam gear has a cam slot with an inertial detent. A vibratory feedback is provided to an assembler indicative of a properly positioned connector housing when the pin is moved past the inertial detent.

In an open position, a power-supply terminal and a detection terminal are not connected to a mating power-supply terminal and a mating detection terminal, respectively. In a predetermined position, the power-supply terminal is connected to the mating power-supply terminal while the detection terminal is not connected to the mating detection terminal. In a closed position, the power-supply terminal and the detection terminal are connected to the mating power-supply terminal and the mating detection terminal, respectively. When the connector is turned toward the predetermined position from the closed position, a first regulating portion regulates a first regulated portion to prevent the connector from reaching the predetermined position. When the connector is turned toward the predetermined position after the regulation is released, a second regulating portion regulates a second regulated portion to prevent the connector from being turned toward the open position beyond the predetermined position.

A wire cover (70) is arranged to cover a rear surface of a housing (10) and includes a back plate (73) in a rear part. A pull-out port (77) for wires (30) is provided in an end part of the back plate (73) and an opening (74) is provided separately from the pull-out port (77). A U-shaped lever (90) is arranged to straddle the back plate (73) and connects the housing (10) and a mating housing at a connection position by being rotated with an operating portion (91) gripped. The operating portion (91) of the lever (90) enters the opening (74) at the connection position and is arranged in contact with or in proximity to an edge of the opening (74).
