An electrical connector comprises a housing body with a peripheral region and a central region. A hinge support protrudes from the housing body. A curved wall portion extends outward from the central region. A lid has a hollow portion arranged for rotation with respect to the hinge support. A spring or resilient member is configured to bias the lid in a closed state against an electrical socket with one or more electrically conductive terminals in an interior of the electrical socket. A slider is arranged to slide radially along the curved wall portion between an open position and a closed position, where the closed position holds the lid in the closed state and where the open position allows the lid to be rotationally raised or flipped upward.

A connector includes a housing provided with an accommodating cavity and a first opening communicating with the accommodating cavity; a circuit board disposed in the accommodating cavity and provided with a first signal connection point; a connection head disposed on the housing and including a second signal connection point for external device connection; and a switch disposed in the first opening, being respectively connected to the first signal connection point and the second signal connection point. The switch is used for controlling the connection or disconnection between the first signal connection point and the second signal connection point. In the above-mentioned manner, the connector and a heavy load may be disconnected by the switch when the connector is pulled out, so that risks of instant ignition and short circuit caused by the connector pulled out may be avoided, and safety accidents may be reduced.

A board connector includes a first housing including a base and two sidewalls, plural first terminals retained in the base and located between the two sidewalls, and a first metallic shell enclosing the first housing and including a pair of first engaging portions at the sidewalls and a pair of first locking portions located in front of the sidewalls. A cable connector includes a second insulating housing and defining two opposite sides, plural second terminals retained in the second housing, and a second metallic shell enclosing the second housing and including a pair of second locking portions and a pair of second engaging portions behind the second locking portions. The first locking portions are locked with the second engaging portion, and the second locking portion are locked with the first engaging portions after the board connector and the cable connector is mated with each other.

A plug connector includes: an insulative housing having a front mating end and a rear terminating end; a conductive module received in the insulative housing and exposed to the front mating end; a rod mounted to the insulative housing; a latch mounted to the insulative housing, the latch including a securing portion, a latching portion movable between a latched position and a released position, and an operating portion operable by the rod to move the latching portion to the released position; and a pulling tab connected to the rod, wherein the insulative housing includes a pair of grooves and the rod is slidable in the pair of grooves by the pulling tab to operate the operating portion of the latch to move the latching portion to the released position.

The invention relates to a round plug connector for detachably connecting lines, comprising at least one housing element for receiving at least one insulating body and at least one locking element for detachably connecting to a counter plug connector. The housing element also receives at least one circumferential spring element. The spring element is produced for connecting an electromagnetic shield made from an electrically conductive material and has at least one ring retained in a circumferential recess in the housing element and at least one substantially axial wing.

An adapter includes a socket portion and a power-taking portion. The power-taking portion is connected to a bottom of the socket portion, and the power-taking portion is configured to enter an electrified guide rail to take power. The socket portion includes a socket portion body, a fixed support, a locking member and an unlocking member. The fixed support is disposed at a bottom of the socket portion body. The locking member runs through the fixed support, and the locking member is configured to be limited within the electrified guide rail in a locked state and to be released from the electrified guide rail in an unlocked state. The unlocking member is connected to the fixed support, and the unlocking member is configured to enable the locking member to be switched between the locked state and the unlocked state.

A plug connector includes a housing, a built-in circuit board partially located in the housing, and a cable electrically connected to the built-in circuit board. The housing includes a mating surface. The built-in circuit board includes a tongue plate and a number of conductive pads provided on the tongue plate. The housing includes an extension plate extending along a mating direction of the plug connector. The tongue plate and the extension plate protrude beyond the mating surface along the mating direction. The extension plate further protrudes beyond the tongue plate along the mating direction. Two lateral sides of the plug connector also respectively include slots extending through the mating surface. As a result, the insertion reliability of the plug connector of the present disclosure is improved.

A connector retainer attached to a connector device includes a cover, a locking arm, an engagement arm, and an engagement claw. The cover has a surface being flat and extending in a direction parallel to an engagement direction in which a first and second connectors of the connector device are engaged. The cover is configured to cover an outer surface of an engagement maintaining mechanism for maintaining the engagement state of the connectors. The locking arm projects from the surface of the cover in a direction crossing the engagement direction. The engagement arm projects from the surface of the cover in the direction crossing the engagement direction. The engagement claw is disposed at a tip end of the engagement arm, and is configured to engaged with a projection of the second connector.

A pull strap connector includes an insulating housing, a number of conductive terminals, a movable element, an elastic member, and a pull strap. The insulating housing includes a main body and a tongue plate. The main body includes a first end wall and a second end wall. The movable element includes at least one first locking protrusion protruding forwardly from the first end wall for engaging with a first locking hole of a mating connector. The movable element includes at least one ejector rod. The movable element includes at least one second locking protrusion on a rear end of the ejector rod. The second locking protrusion protrudes forwardly towards the second end wall for engaging with a second locking hole of the mating connector. The pull strap is configured to drive the movable element to overcome the elastic member so that the movable element moves along a front-back direction.

A socket connector includes a housing having a cavity and a pin access opening through the bottom open to the cavity configured to receive a pin. The housing includes a latch pocket open to the cavity. A socket is received in the cavity electrically connected to the pin and a cable to electrically connect the cable and the pin. The socket connector includes a latch movably received in the latch pocket between a latched position and a clearance position and configured to engage the pin to secure the socket connector to the pin. The latch includes a latching rib having a latching surface configured to engage the pin in the latched position and released from the pin in the clearance position to allow uncoupling of the socket connector from the pin.
