There is provided a connector in which a plug is put to a socket in any rotational direction around an axis and is guided to a normal position smoothly thereby providing proper connection with a simple structure.

On opposite surfaces of the plug and the socket, there are provided a tilted cam surface and a cam follower with which the plug and the socket are slidably contacted to each other, rotated and positioned in a rotational direction around the axis when the plug is fitted onto the socket axially. At the center of one of the opposite surfaces of the plug and the socket, a pin-receiving hole is formed, and a center pin at the center of the other fits into the pin-receiving hole before the tilted cam surface comes in contact with the cam follower.

The present invention concerns a connection system comprising: a plurality of connection plugs on each of which is mounted a locking lever with two arms each one supporting a locking hook of a locking system, an assembly comprising: an electrical equipment box panel, designed to lodge an electronic circuit card, the panel comprising a plurality of openings; a plurality of adjacent sockets. According to the invention, the plurality of sockets is monobloc with the equipment panel and the sockets and the plugs are configured such that when each plug is connected to one of the sockets and locked to the latter by means of the locking lever in the position of attachment of the hooks to the locking lugs of the socket, two adjacent arms of adjacent plugs are in planar, pointlike or linear bearing against each other.

This disclosure regards a self-keying system for an input/output (I/O) device. An I/O module mountable on a terminal base exchanges I/O signals with external devices via the terminal base. The I/O module comprises a key, and the terminal base comprises a locking assembly to allow insertion of only compatible I/O modules into the terminal base. The locking assembly comprises parallel slots containing a plurality of lock pins movable in the slots between a biased position and a second position. A blocking member is actuated by the key to block each of the lock pins in their respective position to key the base. A maintaining member maintains the blocking member in the keyed position. After keying, a non-compatible key would be rejected from the locking assembly due to the blocked lock pins. A reset to the unkeyed configuration may be accomplished without the use of tools by actuating the maintaining member.

A connector comprises a first housing, a cam member, and an operation lever. The first housing has a mating portion configured to mate with a second housing of a second connector. The cam member has a cam groove configured to mate with a cam pin provided on the second housing. The cam member causes the second housing to mate with the first housing by sliding in a lateral direction intersecting with a direction of mating to draw the cam pin into the cam groove. The operation lever slides the cam member according to a turning operation. A nipping portion of the connector nips the cam pin in the cam groove when the cam member slides up to a mating completion position at which mating of the second housing with the first housing is completed.

A connector having a housing, a slide member, and an operation lever. The slide member slides in response to operation of the operation lever. The slide member has a guide projection and slides while the guide projection is guided in a guide groove of the housing. The slide member has a cam groove that receives a cam pin in a second connector and the slide member, by sliding, performs mating with the second connector. The slide member has a first nipping portion that nips the cam pin when it slides to a completely mated position. The housing has a second nipping portion that nips the guide projection of the slide member when the slide member slides to the completely mated position.

A connector assembly includes an electrical connector and a shipping cap. The electrical connector includes a housing and a lever pivotably coupled to the housing. The lever is pivotable relative to the housing between an open position and a closed position. The lever has a guideway configured to receive a guide journal of a mating connector that mates to the electrical connector. The shipping cap is removably mounted to a mating end of the housing when the electrical connector is not mated to the mating connector. The shipping cap includes a lid that covers a mating opening of the housing. The shipping cap further includes a blocking tab that is received in the guideway of the lever when the lever is in the open position. The blocking tab in the guideway engages the lever to block the lever from pivoting to the closed position.

A lever-type connector includes a housing having support holes; a fitting part provided inside the housing and fitted in a counterpart connector; a lever that includes a pair of plate-like portions facing each other in an opposed manner, a connection portion connecting the pair of plate-like portions with each other, and projection portions provided respective outside surfaces of the pair of plate-like portions, the lever being rotatably supported by the housing while the projection portions are engaged with the support holes; and sliding members each includes a guide portion that is slidably supported by the housing and engaged with a part to be guided provided to the counterpart connector, the sliding members being slid depending on a rotation of the lever to depress the part to be guided by way of the guide portion and fit the counterpart connector in the fitting part.

A slide lever (30) provided on a fit-in side housing (F) includes cam functioning portions (31) configured to enter the receptacle (11) in the process of connecting the waiting side housing (M) and the fit-in side housing (F), and the cam functioning portions (31) are formed with cam grooves (32) to be engaged with cam followers (15) in the process of connecting the two housings (F, M). An operating portion (33) projects substantially parallel to a moving direction of the slide lever (30) from rear end parts of the cam functioning portions (31) in an entering direction into the receptacle (11) and is arranged forwardly of a front face (S) of the panel (P).

The present invention aims to improve heat dissipation effect for an electrical component in a socket for electrical component in which a socket body and a cover member are separated. According to an embodiment, a cover member includes a frame-like cover body including an opening in a middle portion thereof, a heatsink provided to penetrate through the opening of the frame-like cover body, an elevating part supporting the heatsink, and a pressing part that is moveable to press the elevating part so as to press the heatsink against the electrical component. While the heatsink is pressed against the electrical component, the electrical component is fixed to the housing portion of the socket body. Accordingly, it is possible to make the heatsink perform heat dissipation for the electrical component. Thus, it is possible to obtain excellent heat dissipation effect with respect to the electrical component.
