An electrical connector having a mate assist system including a user actuatable member which slides along an operating direction between a rear position and a forward position, a first and a second rack sections extending parallel to the operating direction, and first and second rotatable cam members having a cam slot configured to receive a respective mounting pin protruding from a mating electrical connector. Each rotatable cam member engages a respective rack section and the first and second cam members rotate in opposite directions when the user actuatable member is moved from its rear position towards its forward position.

An electrical connector assembly includes a first electrical contact device and a second electrical contact device. The first electrical contact device includes a plurality of conductors. The second electrical contact device includes a first portion, a second portion movable in a rotational and translational manner relative to the first portion, and an actuator movable between a first position and a second position. The first portion includes first electrical contacts, and the second portion includes electrical sockets. Each socket receives an associated conductor and includes a second electrical contact aligned with an associated first electrical contact. The second portion is biased away from the first portion. When the actuator is in the first position, the actuator inhibits translational movement of the second portion toward the first portion. When the actuator is in the second position, the second portion is movable toward the first portion to permit the second electrical contacts to engage the first electrical contacts.

A terminal metal fitting (10) includes a tubular box portion (11) receiving a counterpart terminal; a lock hole (14) formed through a wall (11a) of the box portion (11) and receiving the lock projection (25); a terminal spring (16) extending from an inner wall surface of the box portion (11) to press and contact to the counterpart terminal; and a supporting point portion (15) formed at a portion around the lock hole (14) to have a cantilevered-shape. The supporting point portion (15) serves as a supporting point (15a) when the terminal spring (16) contacts to the counterpart terminal.

A connector, a bayonet-style connector, and methods for using the connector or bayonet-style connector are provided. At least one connector includes a receiver having an inner volume to receive a connector, and having a pawl; and a pushbutton or actuator that operates to move or unlock the pawl so that a user can insert and lock and/or unlock and remove the connector using only a single hand of the user. At least one bayonet-style connector includes a connector portion having an opening; a receptacle portion that operates to slidingly accept the connector portion and that has a pawl that operates to engage with the opening to lock the connector portion in place; and an actuator that operates to impart force on the pawl to unlock the connector portion so that a user can remove the connector portion using only one hand of the user.

An electrical connector assembly includes a first electrical contact device and a second electrical contact device. The first electrical contact device includes a plurality of conductors. The second electrical contact device includes a first portion, a second portion movable in a rotational and translational manner relative to the first portion, and an actuator movable between a first position and a second position. The first portion includes first electrical contacts, and the second portion includes electrical sockets. Each socket receives an associated conductor and includes a second electrical contact aligned with an associated first electrical contact. The second portion is biased away from the first portion. When the actuator is in the first position, the actuator inhibits translational movement of the second portion toward the first portion. When the actuator is in the second position, the second portion is movable toward the first portion to permit the second electrical contacts to engage the first electrical contacts.

The implantable blood pump system includes an implantable blood pump, a controller coupled to the blood pump, a connector receptacle, and a connector insert. The connector receptacle can include a plurality of contacts, and a following surface. The connector insert can be received within the connector receptacle to couple a plurality of insert contacts with the plurality of contacts of the connector receptacle.

A housing (10) is formed with a partial locking stopper (21) and a full locking stopper (24). A slide lever (25) (operating member) is formed with a single hook (33) having a partial locking contact surface (35) and a full locking contact surface (36). The partial locking contact surface (35) is at an acute angle to a sliding direction of the slide lever (25) and restricts a movement of the slide lever (25) at the partial locking position in a direction separating from the housing (10) by contacting the partial locking stopper (21). The full locking contact surface (36) is at an obtuse angle to the sliding direction of the slide lever (25) and restricts a movement of the slide lever (25) at the full locking position toward the partial locking position by contacting the full locking stopper (24) in a semi-locked state.

A lever 50 is arranged movably from a partial locking position before connection of both housings 10, 90 and a full locking position after the connection with respect to the housing 10. Entrances 56 of cam grooves 54, 55 of the lever 50 are open in an edge part of the lever 50. The housing 10 includes a lock piece 31 resiliently displaceable in a direction intersecting a moving direction of the lever 50 to the full locking position. The lock piece 31 includes a lock portion 35 arranged at entrances 56 of the cam grooves 54, 55 and facing inner surfaces of the entrances 56 with the lever 50 located at the partial locking position. The lock portion 35 includes a protruding portion 37 projecting from the entrances 56 of the cam grooves 54, 55.

A first housing 10 includes a resiliently deformable lock arm 30. The lock arm 30 has a lock surface 34 to be arranged to contact a front surface of a panel 90 with the first housing 10 arranged in a mounting hole 91 of the panel 90. A second housing 40 includes a space portion 53 into which an arm plate 72 of a lever 70 is arranged, leg portions 57 rising from the side of an outer wall 52 of the space portion 53 while facing each other, and a bridge portion 58 extending between the leg portions 57 facing each other. The bridge portion 58 includes a releasing portion 65 capable of releasing a state where the lock surface 34 is in contact with the front surface of the panel 90.
