A battery module includes: a lower housing in which a plurality of secondary battery cells are housed; an upper housing coupled to a cover of the lower housing to cover the plurality of secondary replaceable cells; a female connector detachably installed in at least one of the lower housing and the upper housing; and a wiring harness electrically connected to the connector and the plurality of secondary battery cells. The connector may include a body provided with a plurality of terminals, a bottom surface of the body may be spaced apart from an outer surface of the at least one housing such that a space may be defined between the outer surface of the at least one housing and the bottom surface, and both side surfaces of the body may be securely connected to the outer surface of the at least one housing.

An electrical connector comprises an insulating body, a pair of first terminal members, a pair of second terminal members, and a fastening part. The insulating body comprises a mating groove. The pair of first terminal members is disposed in the mating groove. Each of the first terminal members comprises a plurality of first elastic contacting parts. The pair of second terminal members is disposed in the mating groove. The pair of first terminal members is disposed between the pair of second terminal members. Each of the second terminal members comprises a plurality of second elastic contacting parts. The second elastic contacting part abuts against the first elastic contacting portion correspondingly. The fastening part fastens the pair of first terminal members and the pair of second terminal members.

A receptacle connector includes an insulative receptacle housing and a plurality of receptacle contacts retained in the receptacle housing. The plug connector includes an insulative plug housing and a plurality of plug connectors retained in the plug connector. The receptacle housing includes a rear wall extending along a lengthwise direction, and a pair of side walls extending from two opposite ends of the rear wall along the front-to-back direction perpendicular of the lengthwise direction, to commonly form a receiving space thereamong. The receiving space forms a front opening and an upper opening for communicating with an exterior. The receptacle contacts are retained in the rear wall and extend into the receiving space. The plug connector is adapted to be rearwardly inserted into the receiving space along the front-to-back direction via the front opening, or be downwardly and rotationally inserted into the receiving space via the upper opening.

An electrical connector having a housing having a pin plate holder and a pin block holder. The pin block holder has a pin block holder stabilizing section. The pin plate holder has a pin plate holder stabilizing portion. With the pin block holder and the pin plate holder fully mated, the pin block holder stabilizing section engages the pin plate holder stabilizing portion to prevent the movement of the pin plate holder relative to the pin block holder in multiple directions.

A network port connector ejection system includes a computing device connector that is connected to a network port connector. A retention device in the network port connector ejection system is configured to engage the network port connector to secure the network port connector to the computing device connector. A retention device release subsystem in the network port connector ejection system is coupled to the retention device and is configured to be actuated to release the retention device from engagement with the network port connector. A network port connector ejection subsystem in the network port connector ejection system is configured to engage the network port connector, while the retention device release subsystem is actuated to release the retention device from engagement with the network port connector, to disconnect the network port connector from the computing device connector.

A communication system includes a plug module having a plug housing and a plug latch and a receptacle module having a receptacle housing and a receptacle latch. The receptacle module includes a receptacle connector with a card slot receiving a plug module circuit board. The receptacle connector includes cables terminated to contacts and extending from the receptacle connector. A receptacle cage includes a front cage interface receiving the plug module and a rear cage interface receiving the receptacle module. The front cage interface matches the rear cage interface including a front latching feature and a rear latching feature interfacing with the plug and receptacle latches.

A connector assembly including a connector and a counter-connector mated to each other. The counter-connector includes primary locking means including a rotatable coupling aid lever. The lever is in a closed position when the connector and counter-connector are fully coupled. The connector includes secondary locking means rotatably movable about an axis of rotation, between a locking position and an unlocking position and configured to cooperate, in the locking position, with the primary locking means to lock the lever in the closed position.

Disclosed is a plug connector which can be latched to a mating plug connector having a plug connector housing having a plurality of sides each having a flat shape, a plug connector insert which is fixed or at least can be fixed in the plug connector housing, and an unlocking sleeve which engages around the plug connector housing and is held thereon so as to be displaceable counter to the plugging direction. At least one polarization element is mounted on a side of the unlocking sleeve. Also disclosed is a system, a method for mounting, a method for plugging, and a method for separating plug connectors and mating plug connectors.

Disclosed is a connector assembly. The connector assembly includes an adapter, a connector and a handle, where a first socket is formed at one end of the adapter, an adaptation slide extending inwards from the first socket is formed in an inner wall of the adapter, and an adaptation window is opened at one end of the adaptation slide close to the first socket; the connector is provided with an elastic piece, and the elastic piece is movable along a Z-axis direction; and the handle is connected to a rear end of the connector and is capable of sliding between a first position and a second position of the connector along an X-axis direction. The beneficial effect provided is as below. The handle always remains connected to the connector.
