A terminal that is capable of positively scraping off insulation coating of an electric wire. A wire connection portion is formed with a slit. A pair of positioning portions and a pair of supporting portions are disposed with the slit of the wire connection portion therebetween. A spacing between the pair of supporting portions is smaller than a spacing between the pair of positioning portions. Each supporting portion is formed with a corner portion in an end portion thereof toward a positioning portion associated therewith. Each positioning portion is formed with a cutout in an end portion thereof toward the supporting portion. An inner surface of the cutout is continuous with a surface of each corner portion toward the positioning portion.

A technique to reduce workload on an operator during mating of a lever connector is provided. A plug and a receptacle are pulled together by rotation of a lever in a locking direction. The lever has a pinion first driven surface facing in an unlocking direction. A receptacle housing has a rack first driving surface facing in a separating direction. In a state where the plug confronts the receptacle so as to mate the plug with the receptacle, a clearance between the pinion first driven surface and the rack first driving surface is smaller than a clearance between a contact piece and a pin portion. When the plug is moved toward the receptacle, the pinion first driven surface first comes into contact with the rack first driving surface and the lever rotates in the locking direction, and then the contact piece comes into contact with the pin portion.

Lever connector assembly

A receptacle is a connector that is attached to a casing and allows electric wires within the casing to be attached to the connector and includes a receptacle shell. The receptacle shell includes a rectangular tubular portion projecting toward an inside of the casing and covering the electric wires within the casing. The rectangular tubular portion has four outer surfaces respectively provided with drain grooves that are made of metal formed by casting and are continuous with each other. A cross-section of each drain groove has an asymmetrical shape in which a deepest portion of each drain groove is farther from a tip of the rectangular tubular portion than a groove width center of each drain groove. The deepest portion is raised at a center of each drain groove in a longitudinal direction so that a water droplet within each drain groove moves toward ends of each drain groove.

[Problem] To prevent a receptacle connector and a plug connector from being erroneously released from a state locked to each other by hand, and to make it possible to easily remove the plug connector from the receptacle connector by an operator alone. [Solution] A receptacle housingof a receptacle connectoris provided with through holes. A plug housingof a plug connectoris provided with protrusionswhich can be engaged in the though holes, and leaf springswhich urge the protrusionstoward the through holes. An unlocking jigis formed by a jig main bodywhich can be mounted and removed to and from the receptacle housingof the receptacle connectorin a direction Dperpendicular to a fitting and removing direction D, and the protrusionswhich are provided on the jig main bodyand press lugsagainst an urging force of the leaf springswhen the jig main bodyis mounted to the receptacle connectorto thereby disengage the lugsand the through holes

Unlocking device, connector device, and connector

A contact which makes it possible to make a connection unit compact in size. A pair of supporting portions opposed to each other in a predetermined direction are provided on opposite side edges of a plate-shaped base portion with which an associated one of electrodes of a photovoltaic unit is brought into contact, such that the supporting portions rise from the opposite side edges, respectively. The pair of supporting portions are each formed with a slit for supporting a terminal portion of a diode.

Pin connector

Socket connector

A connector that has a high waterproof property, and can be easily assembled. A housing is formed with a through hole for accommodating a contact which is connected to a cable. An elastic sealing member that has a hollow cylindrical shape and is fitted on an outer peripheral surface of the cable is accommodated in a rear portion of the through hole, and an urging member having a hollow cylindrical shape is fitted on an outer peripheral surface of the housing. The urging member is formed with a tapered surface for urging a rear end of the elastic sealing member against the outer peripheral surface of the cable when the urging member is fitted on the outer peripheral surface of the housing.

Connector

Plug connector

A connector capable of setting a direction of running a cable connected thereto, as desired. An angle end bell has eight positioning protrusions formed on a foremost end of a surrounding portion thereof at circumferentially equally-spaced intervals. Eight positioning recesses for engagement with the positioning protrusions are formed in a rear end of a barrel. The barrel has three erroneous fitting-preventing key grooves formed in an outer peripheral surface thereof at circumferentially equally-spaced intervals.
