Various disclosed embodiments include illustrative vehicle charging connectors, vehicle charging connector systems, and vehicle charging systems. In an illustrative embodiment a vehicle charging connector includes at least two electrical contacts configured to electrically connect with electrical contacts of a vehicle charge port. At least one controllable electromagnet may be configured to attract the vehicle charging connector to contact a charge port of an electric vehicle. The connector also includes at least one controllable electrically actuated mechanical connector configured to provide mechanical engagement and disengagement between the vehicle charging connector and the charge port.

An optical connector includes an optical fiber, a ferrule provided at an end portion of the optical fiber, a plug housing in which the ferrule is accommodated, a lock arm provided on the plug housing and holding the plug housing and the mating housing in a fitted state, a holder assembled to the plug housing to hold the ferrule in the plug housing, and a holder protrusion provided on the holder and pressed by the lock arm which is flexibly deformed in an unlocking direction by a predetermined amount or more so that the holder is displaced in a direction of releasing the ferrule from being held by the holder.

A moving plate moves from a protection position for protecting a tip part of a male tab to a connection position in a receptacle according to a connecting operation of a female housing. A male housing includes a male housing lock, and the female housing includes a female housing lock. The moving plate includes a plate male lock for locking the male housing lock at the protection position to restrict a movement to the connection position, and a plate female lock for locking the female housing-side locking portion to restrict separation of the female housing when locking of the male housing lock and the plate male lock is maintained.

Prior-art connectors require burdensome operations that involve connecting the male screws of the threaded retaining members mounted on an overmolded connector unit to the internal threads provided in a counterpart connector and tightening the screws by turning in order to prevent connector disengagement. In addition, repeatedly attaching and detaching the connector may create a problem by increasing the burden of such operations. The present invention provides a connector and a connector device that allows for easy attachment to and detachment from a counterpart connector by providing a locking mechanism that automatically locks upon connection to a counterpart connector and that permits unlocking by depressing buttons in a connector that includes a connector unit provided in a distal end section of a cable and a housing that holds said connector unit inside and is equipped with a locking mechanism for locking to a counterpart connector.

A connector assembly is provided with a first connector and a second connector. In the first connector, a first contact point portion, a first indented portion, a first lock portion and a regulated portion of a first terminal are supported by a spring portion. A first holding member holding the first terminal has a regulating portion. The regulated portion is located downward of the regulating portion and faces the regulating portion. In the second connector, a second terminal held by a second holding member has an insertion end portion, a second contact point portion, a second indented portion and a second lock portion. In a mated state, the first lock portion and the second lock portion are located between the first indented portion and the second indented portion and face each other in the up-down direction.

A plug connector includes an insulating body, an elastic latch, and a blocking bar. The blocking bar is connected to the insulating body and spans a pushing portion of the elastic latch. The pushing portion has at least one hook and a pushing end hung in the air. The blocking bar is located between the hook and the pushing end for protecting the pushing end.

A battery maintenance system for use in performing battery maintenance on a battery of an electric vehicle including a battery maintenance device and a high voltage connector configured to connect the battery maintenance device to the battery of the electric vehicle. When a fuse door is removed from a fuse block of the connector, a mechanical component in a first position blocks a keying post and prevents a first connector side from coupling with a second connector side of the connector When the fuse door is in place and covering an interior of the fuse block, the fuse door places the mechanical component into a second position to allow the keying post to mate with the second connector side and to activate an electric switch to connect voltages to the fuse block.

A coaxial connector and a coaxial cable forming a cable assembly. The coaxial connector includes a cable entry side for entry of the coaxial cable and an opposite coupling side for coupling with the coaxial counter connector along the connector axis. The coaxial connector includes an inner contact element electrically connected with an inner conductor of the coaxial cable; an outer contact element electrically connected with an outer conductor of the coaxial cable; a dielectric connector element radially arranged between the inner contact element and the outer contact element; a connector housing arranged around the outer contact element; wherein the inner contact element is axially locked against the dielectric connector element and the dielectric connector element is axially locked against the connector housing such that the coaxial cable is strain relieved in an axial direction with respect to the connector housing.

An electrical cable connecting system includes a modular electrical or electronic wiring device assembly, in which an electrical or electronic wiring device and a connector may be electrically coupled via pig-tail jumper electrical wires. The connector may be coupled to cable electrical wires fitted with a cable protector to protect the electrical wire conductors therein. The connector may include internal electrical terminals for electrically coupling building electrical cable wires with corresponding jumper electrical wires. The connector may be mechanically and electrically coupled to and directly terminate one or more building electrical cables, which may provide power to or from one or more electrical or electronic wiring devices by establishing an electrical pathway from a source of electrical power, through the building electrical cable wires, the connector, the pig-tail jumper electrical wires and an electrical or electronic wiring device.

When securing a watthour meter to a meter box base, a meter sealing ring is typically used. A quick-fastening watthour meter retaining member is provided, in certain embodiment of the present invention, to reduce installation time and generally comprises a circular band, a connector housing member, and a receiver housing member. The connector housing member and a receiver housing member are preferably mounted to the terminus ends of the circular band. A portion of the connector housing member, comprising locking protrusions or “teeth”, is adapted to engage, with a ratchet-type action, in one example embodiment, and fasten into the receiver housing member, which contains, a pre-installed “padlock type” frangible sealing device in an example embodiment. Removal of the ring is accomplished by simply cutting, in one embodiment, and removing the frangible sealing device and allowing the housings to disengage from each other.
