A lever type connector includes a housing configured to fit to a mating connector and a lever mounted on the housing and configured to draw the mating connector and the housing closer to each other when the lever moves from a temporary locking position to a final locking position. The lever includes a temporary locking arm which is elastically deformable in a direction away from a surface of the housing, and rotates between the temporary locking position and the final locking position while the temporary locking arm comes into press-contact with a sliding surface which is part of the surface of the housing.

Lever type connector that prevents the pivot of the lever from being inclined

A lever-type connector includes a housing and a lever movably attached to the housing. The lever includes a side plate provided along a side surface of the housing, and an operation portion connected to the side plate. A boss is provided on the side surface of the housing. The side plate of the lever has an elongate hole into which the boss is inserted to restrict a moving range of the lever. An engagement stepped portion is provided at one end of the elongate hole. The engagement stepped portion is recessed on its outer side. The boss has an engagement projection provided at its distal end portion. The engagement projection extends along the elongate hole. The engagement stepped portion and the engagement projection engage with each other in a state in which the lever has been moved in a direction that separates the housing from a counterpart housing.

Lever-type connector capable of operability

A terminal includes a box-shaped body part including a pair of a first side wall and second side wall which are raised from both side ends of a bottom wall, a top wall extended from the first side wall, and an auxiliary wall extended from the second side wall. The top wall includes a first slit opening on a side end face of the top wall. The auxiliary wall includes a second slit opening on a side end face of the auxiliary wall. A stabilizer is formed by a portion on a front side of a separating portion formed by the second slit. A stabilizer reinforcing section is formed by a portion on a front side of a separating portion formed by the first slit. An engagement section is formed by a portion on a rear side of the separating portion formed by the first slit of the top wall.

A electrical wire cover has a corrugated tube fixing portion () and engagement projection strips () which are integral parts of a cover body () which surrounds electrical wires, a electrical wire tie which fixes, that is, tightly fastens, one of first to third corrugated tubes, and tying member restricting portions () provided in the corrugated tube fixing portion (). Each tying member restricting portion () has plural, that is, first to third, positioning portions (and) having different electrical wire tie bridging positions.

Electrical-wire-protecting member

A water draining structure for an electric wire cover () includes: a wall () for covering the surroundings of an electric wire to be routed; a pair of slit openings () penetrating through the wall (); and a water guiding protrusion () rising from each of adjacent opening edges () of the pair of slit openings () and protruding from an inner surface () of the wall () so as to have an apex part () of curved surface shape.

Water draining structure for electric wire protection member

A connector is provided which includes a housing in which a terminal is accommodated, and a retainer which is mounted on the housing to prevent movement of the terminal in the direction of detachment. A retainer insertion hole is provided on the housing to insert the retainer, and a provisional locking projection and a final locking projection are provided which extend into the retainer insertion hole. A guide portion is provided in the retainer which is flexibly deformed by interference from the provisional locking projection and the final locking projection, and a locked portion is formed, which is a locking hole opened in the guide portion. The locked portion and the provisional locking projection are temporarily locked during the insertion process, and the locked portion and the final locking projection are locked at the end of the insertion process.

Connector

A connector includes: a terminal including a box part which covers a terminal-contact spring, a crimped part which holds a core wire, and a concave part formed between the box part and the crimped part; and a housing integrally including an insertion port from which the terminal is inserted, an accommodation chamber in which the terminal is accommodated, an band which constitute a part of the accommodation chamber and is put into a double end-supported state so that the elastic band is pressed and elastically deformed by the box part of the terminal when the terminal is inserted in the housing from the insertion port, a lance which protrudes from an intermediate part of the band to engage the concave part of the terminal, and a reinforcement part which protrudes from the lance toward a bottom side of the housing to enter in the concave part of the terminal.

Connector with reinforced structure

A terminal is formed by bending a plate of electrically conductive metal and is received in a connector housing. The terminal includes a box-shaped body part, a terminal contact part provided on a front side of the body part, and an electrical wire connecting part provided on a rear side of the body part. When the plate before bending is viewed from the thickness direction, a conductor section having a cross-section having constant width and thickness extends from the terminal contact part to the electrical wire connecting part.

Terminal

A connector provided with a female-type metal terminal fitting, includes a case portion including a bottom plate portion, first and second side plate portions, and an upper plate portion, a lance engaging portion formed at a rear end portion of the upper plate portion so as to engage with a lance, a biasing portion integrated in the case portion, a wire connecting portion provided so as to be extended to a rear side of the case portion, and a spring supporting plate portion laminated on an inner face of the upper plate portion. A rear end portion of the spring supporting plate portion is recessed toward inside of the case portion further than the rear end portion of the upper plate portion. The biasing portion is extended from the spring supporting plate portion.

Female-type metal terminal fitting

To provide a connector in which a lance beak part will not be broken, even though a large load is applied by a front holder. A locking lance is provided, at its distal end, with a lance beak pad which is adapted to be caught by a lock releasing jig for releasing lock of the locking lance with respect to a terminal, and a locking projection which is continued from the lance beak part and erected from a terminal end of the lance beak part. When a projected part is inserted into e deflection space in a state where the locking lance is deflected, a lower face of the projected part overrides an upper face of the lance beak part, and a distal end of the projected part comes into contact with a vertical face of the locking projection which is erected from the lance beak part.

Connector having locking lance with lance beak part and locking projection

Either of first and second corrugated tubes having different groove (or ridge) pitches can be mounted on a connector. In this case, the distance between a first retaining projectionand a second retaining projectionis a common multiple of these pitches, and therefore either of the two different corrugated tubes can be properly retained on both of the first and second retaining projectionsand. Furthermore, either of the first and second corrugated tubesandof different diameters can be properly fixed to a tube insertion portionby a binding band passed through binding band passage holes

A lever-fitting connector includes: a first connector; a second connector having a retaining portion; and a rotatable lever which engages the first connector with the second connector. The rotatable lever includes a retaining arm for provisionally retaining the lever with the second connector to abut on the retaining portion. The retaining arm extends to form a slit between the retaining arm and an edge of the rotatable lever. A width of the slit is smaller than an elastic range of the retaining arm at which the retaining arm bends toward the edge.
