Abstract: An easy-operation-type connector includes a male connector, a female connector to be engaged with the male connector, and a driving lever for coupling and detaching the male and female connectors. The male connector includes a male connector main body, a first top face formed on the male connector main body, a driven recess formed in the male connector main body, an inclining face formed as an inner wall of the driven recess, and vertical face formed as an inner wall of the driven recess. The female connector includes a female connector main body, a second top face formed on the female connector main body, a receiving recess formed in the female connector main body, an engaging recess formed in the female connector main body, and an aperture formed in the female connector main body. The driving lever includes a driving lever main body, an engaging projection formed in the driving lever main body, a driving projection formed in the driving lever main body.

Abstract: An electrical connector includes a housing having terminal chambers, terminals which are inserted into the chambers, and a terminal engagement holder provided with a locking anchor for an engagement portion of the housing in order to be assembled with the housing by two-steps of manipulation, which are a step of tentatively engaging the holder with the housing, and the other step of thereafter engaging the holder with the housing on a full scale. The locking anchor functions to urge the holder toward the housing while the holder is in the full-scale engagement with the rear portion of the housing, so that the holder can be surely engaged with the housing on the full scale even if the rear end of each of the terminals is located slightly behind a prescribed position.

Abstract: A watertight electric connector has a male connector housing, a female connector housing to be mated with the male connector housing, a ring-shaped packing in close contact with an outer wall of the male connector housing, and a slidable protection cover disposed so as to cover the periphery of the packing. The protection cover protects the packing when the connector housings are not mated with each other, and is moved backward by the pressure of the female connector housing when the connector housings are mated. The slidable protection cover has a mechanism capable of making the watertight connector compact, simplifying the handling of the connector, assuring protection of the packing, and enhancing reliability of waterproofing.

Abstract: A connector comprise a pair of connector housings including one connector housing including a flexible arm having an engaging projection and the other connector housing including an engaging portion corresponding to the engaging projection; lock release prevention device for locking the connector housings to each other by moving the lock release prevention device from a temporary engaging position to a completely engaging position; and an accommodating device, formed on the other connector housing, for accommodating the lock release prevention device.

Abstract: A waterproofing connector including a housing provided with a plurality of chambers in which wiring harnesses are fixed and with a rigid grid consisted of plates for partitioning the chambers, and a seal for sealing an end of the housing, the seal being provided with a plurality of holes in which the wiring harnesses are passed through to the chambers and with grooves for partitioning the holes. The plates of the rigid grid are inserted securely in the grooves of the seal respectively when the end of the housing is covered by the seal. The holes of the seal do not deform nor shift from chambers of the housing when the seal is put in the housing for sealing and when wiring harnesses are passed through the holes to the chambers, and good waterproofness is obtained between the holes and the wiring harnesses.

Abstract: A multi-stage connector is disclosed in which a plurality of connector housings each having open terminal receiving chambers are slidably received in a connector housing body in a multi-stage stacked manner; a retainer projection and a fixing projection are formed on an outer surface of the connector housing; a real retainer window and a provisional retainer window are formed in the connector housing body and juxtaposed in a direction of pulling of the connector housing; and a cover having fixing windows is engaged with the fixing projections.

Abstract: A connector is disclosed wherein a flexible retaining piece for engagement with a terminal is disposed in a terminal receiving chamber of a housing body, and a spacer for preventing the flexing of the flexible retaining piece is inserted into a gap which allows the flexing of said flexible retaining piece. The abutment wall is provided in the housing body in opposed relation to a side surface of the flexible retaining piece. The spacer is provided in the gap so as to slide in a direction perpendicular to the side surface of the flexible retaining piece. Engaging holes and flexure prevention portions for the flexible retaining pieces are provided on the spacer and are arranged in the direction of slide of the spacer.

Abstract: A press-connecting connector of the waterproof type, comprising: a press-connecting connector housing including a cover portion which surrounds wire press-connecting portions in such a manner that the wire press-connecting portions are open in the direction of the press-connection; and a wire holder which comprises a seal member for fitting in the cover portion in a watertight manner; wire passing holes formed through the seal portion; wire holder members disposed in opposed relation to the corresponding wire press-connecting portions when the wire holder is fitted in said cover portion and wire retainer members for retaining the electric wires, passing through the wire passing holes, on the wire holder member, respectively.

Abstract: A movable connector having a movable housing which is to be secured to a panel is provided with spring members on for insertion into a fitting groove formed in the panel. The spring members serve to flexibly absorb displacements caused when a partner housing from a partner connector is fitted to the movable housing.

Abstract: To allow a worker to check whether two first and second matable connector housings are securely engaged with each other and further to firmly lock the two connector housings, the first connector housing is provided with a pivotal locking member pivoted when the two connector housings are engaged with each other, and further locked to an arm locking bridge portion provided at the second connector housing when further pivoted by the worker for connector locking.

Abstract: An electrical connector having a reduced amount of bending of engaging walls thereof during molding. The connector has engaging walls formed of a synthetic resin by molding and which are generally rectangular in section. Portions of the engaging walls other than side and front edge portions are expanded outwardly. This has the effects of both reducing the amount of bening which can occur during molding and accommodating any residual bending which may occur.
