The present invention discloses a connector for a photovoltaic cell. The connector comprises a conductive portion and an insulating portion, wherein the conductive portion is wrapped with the insulating portion; the conductive portion is composed of a conductor and a cable line which are riveted with each other, and a retaining ring is arranged on the outer circumferential surface of the conductor; the insulating portion comprises a shell body, a basket-shaped fastener and a front sleeve; a first inner step surface and a second inner step surface are arranged in an inner cavity of the shell body; the front sleeve has an annular head part which sleeves the conductor; a first outer step surface is arranged at a tail part of the front sleeve, and props against the first inner step surface; the inner diameter of the head part of the front sleeve is larger than the outer diameter of the conductor and less than the outer diameter of the retaining ring. According to the connector disclosed by the present invention, the front sleeve for bearing a stress generated by the retaining ring during a forward extrusion process of the conductor is increased, such that the risks such as cracks originally appearing on the shell body and the like are transferred, and the service life of the whole connector is prolonged.

A connector comprises a first connector and a second connector to be connected with the first connector. The first connector includes a first housing, a holding portion, and a stopper. The second connector includes a second housing, a held portion, and an engagement portion. At the waiting position, the first connector and the second connector are movable between positions in a wall contact state, at which the leading end of the second connector is in contact with the wall defining the receiving space of the first connector, and positions in a stopped state, at which the stopper of the first connector and the engagement portion of the second connector are in contact with each other.

An electric connection plug (5, 5, 5) for an electric cable (3) for use with an electric terminal (20, 21, 20, 21) of a battery module (2, 2). The plug includes a conductive fitting (51, 51, 51) engaged with a rotatable wheel (56, 56, 56) for selectively rotating the fitting to threadingly mechanically and electrically connect to plug to the battery terminal. The cable mechanically and electrically connects to the plug allowing rotation of the wheel and fitting without rotation of the cable while threadingly engaging and disengaging the plug to the battery terminal.

An electrical outlet has a female member with at least two electrically conductive contact sleeves for the reception of the pins on a plug inserted in the female member and a connector arrangement for connection of the electrical outlet to a mains supply. The female member is movable relative to the connector arrangement between a first mode, in which the contact sleeves are electrically disconnected from the mains supply, and a second mode, in which contact sleeves are electrically connected to a mains supply. The connector arrangement include a connection ring and a mounting plate. The connector arrangement further include connection plates, whose number corresponds to the number of contact sleeves on the female member, wherein each contact sleeve is brought in or out of contact with a connection plate by movement of the female member.

A connector is to be joined to a mating connector. The connector includes a terminal fitting including an electrical connection portion to be connected to a mating terminal of the mating connector, a housing including an insertion hole, the electrical connection portion inserted through the insertion hole and a rear holder attached to the housing such that the rear holder presses and holds the terminal fitting against the housing. The housing includes a reference surface to restrict the electrical connection portion, with a portion of the terminal fitting abutting the reference surface, from being further inserted into the insertion hole. The rear holder includes a pressing pin to press, when the rear holder is attached to the housing, the terminal fitting from a rear side of the terminal fitting such that the pressing pin is partially and plastically deformed and the terminal fitting is pressed against the reference surface.
