There is provided a connector including: a sacrificial pressing surface that is provided in a second housing and is a flat surface formed at an end portion on a side opposite in an insertion direction of the second housing. When an external force acts on the second housing in a temporarily assembled state in which the second housing is more shallowly fitted to a first housing than in a fully assembled state and a locking portion is not locked to a locked portion, the sacrificial pressing surface is configured to cause a pressing force to act in a direction in which a contact area of the locked portion with respect to the locking portion is larger than that in a case in which the second housing is pressed in the insertion direction.

Connector

There is provided a connector including: a protrusion portion provided on a second housing at a position close to and facing a distal end portion of a locking portion in a locked state in which the locking portion is locked to a locked portion, so that the protrusion portion restricts an action of an external force on the distal end portion of the locking portion in the locked state.

Connector including locking portion and protrusion portion adjacent to locking portion in locked state

A lever-type connector includes a mating housing having a cam boss, a housing fitted into and detached from the mating housing, a lever rotatably supported by the housing via a lever boss and rotating an operation unit to fit the both housings and a cable cover mounted to the rear of the housing and protecting a plurality of the cables pulled out from the rear of the housing. The lever has a temporary locking lock unit. The housing includes a temporary locking unit that temporarily locks the temporary locking lock unit, and a storage unit that stores the temporary locking lock unit in which the temporarily locked state with the temporary locking unit is released. The mating housing has a release unit that releases the temporarily locked state between the temporary locking lock unit and the temporary locking unit.

Lever-type connector

A lever-type connector includes a first housing having a cam boss and a second housing fitted and detached from the first housing. A lever is rotatably supported to the second housing via lever bosses, and both housings and are fitted by rotating an operating portion. A cable cover is attached to a rear portion of the second housing to protect a plurality of cables drawn from the rear portion of the second housing. The second housing has an assembling portion for assembling the cable cover, and boss holes for rotatably supporting the lever bosses.

Lever-type connector and method of assembling lever-type connector

In a connector, a spacer includes lock parts and regulation parts. Each of the lock parts locks a first terminal in a first terminal receiving slot after the first terminal is inserted into a proper position in the first terminal receiving slot. Each of the regulation parts regulates deformation of a second lance toward a release position when the second lance is located in a lock position in which the second lance locks a second terminal in a second terminal receiving slot after the second terminal is inserted into a proper position in the second terminal receiving slot.

Electrical connector with two types of connector terminals and a spacer inserted into a housing

Provided is an elastic seal member and a connector which can suppress deterioration of a sealing property while suppressing an insertion resistance to a wire insertion hole. A plurality of seal insertion holes (electric wire insertion holes) through which terminal-equipped electric wires are inserted in the thickness direction is arranged and provided, and on at least one of the front and back surfaces a thinned groove is provided adjacent to the seal insertion hole (electric wire insertion hole), and the thinned groove is formed into a shape that does not overlap with a circular range centered on the seal insertion hole (electric wire insertion hole) in a plan view when viewing the one surface, the circular range of the electric wire insertion holes (electric wire insertion hole) adjacent to each other interposing the thinned groove being not overlapping with each other.

Elastic seal member and connector

A connector includes a terminal, a housing, a waterproofing member and a waterproofing member cover. The waterproofing member includes a cylindrical sealing portion in which an insertion hole for the terminal is formed, and a guide portion disposed at least on a rear side in a terminal insertion direction in the insertion hole of the sealing portion and having a tapered shape so as to guide the terminal toward the insertion hole. The waterproofing member includes an elastically-deformable thin portion in a periphery of the sealing portion so that weight generated when the terminal guided to the insertion hole by the guide portion expands the insertion hole is larger than weight necessary for moving the sealing portion in a direction perpendicular to the terminal insertion direction.

In a mat seal cover of a waterproof connector, waterproof pins are provided inside through holes of the waterproof connector and are configured to close terminal insertion holes of a connector housing. The waterproof pins are retained in the through holes by pin retention portions. Coupling portions between the pin retention portions and inner circumferential walls of the through holes are disposed more closely to the front side in the pushing direction of the punching jig than abutment surfaces at rear ends of the waterproof pins against which the punching jig abuts, and rear end faces of the pin retention portions are inclined faces extending from the abutment surfaces toward the coupling portions and inclined to the front in the pushing direction of the punching jig.

Mat seal cover of waterproof connector

A connector includes a connector housing to be fitted to a counterpart connector housing, a pair of lock arms integrally formed on the connector housing and configured to be engaged with a pair of connecting engagement portions of the counterpart connector housing to lock a state of the connector housings fitted to each other, a pair of wedge pieces configured to be assembled into a wedge insertion hole in the connector housing so as to be movable from a standby position to an unlocking position in the connector housing, the pair of wedge pieces being configured to release, when the pair of wedge pieces are pressed to the unlocking position, a locking of the connector housings fitted to each other. Each of the wedge pieces and the wedge insertion hole has an asymmetrical front and rear cross-sectional shape.
