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: An electric connector requiring decreased insertion and withdrawal force, even when including groups of 20 to 40 terminals. The connector includes a male portion, a female portion into which the male portion fits, and a cam mechanism. With the cam mechanism, the male casing fitted in a covering portion of the female casing may be slid horizontally between its original fitting position and a male and female terminal contact position, parallel to the fitting surface of the female casing, so as to slide the male and the female terminals out of or into contact with each other with less force than was required previously.

Abstract: A low insertion-force electrical contact female terminal characterized in that a distal end portion of a flexible base plate portion is folded back to provide a resilient contact portion. A movable support member is mounted on the terminal body and moves in the longitudinal direction of the base plate portion to provide a force to the base plate portion. The flexible base plate portion flexes in response to the force and the integrally attached resilient contact portion also flexes to facilitate entry of a mating male electrical contact terminal. Once the female and male terminals have been connected, the movable support member can be moved again to provide a maximum force to maintain a strong connection.

Abstract: A multi-terminal connector comprising a male housing having a plurality of female terminals stored therein, a female housing having a plurality of male terminals stored therein and provided with an enlarged body for accomodating the male housing, a plurality of guide rails including at least two main guide rails and one supporting rail running in parallel therebetween disposed along the longer side of the enlarged body of the female housing, and also intersecting at right angles against the axis of the male terminals, a pair of sliders each slidably engageable with the guide rails, having a cam follower downwardly projecting from the lower surface thereof, a longitudinal slot formed between the above at least two of rails for permitting each of the cam followers to protrude therethrough, a pair of cam tracks arranged in the upper surface of the male housing and symmetrically extending in a diagonally rearward direction from lateral ends thereof to engage with the respective cam followers through the slot.

Abstract: A multipolar connector comprises male and female terminals disposed in recessed and projected housings and electrically connected to each other by fitting the recessed and projected housings to each other; guide rails disposed in one of the recessed and projected housings; a slider slidably attached to the guide rails and having a cam follower and moved along the guide rails so that the recessed and projected housings are moved towards and away from each other; the one of the recessed and projected housings having a space for allowing the movement of the cam follower; and a guide groove disposed in the other of the recessed and projected housings and engaged with the cam follower through the space.A multipolar connector for fitting a projected housing having a plurality of female terminals and a recessed housing having a plurality of male terminals to electrically connect the male and female terminals to each other.

Abstract: Disclosed is a watertight connector comprising a male connector housing in which a cavity for containing a packing therein is formed by the combination of an outer wall, an upstanding rear wall extending outwardly from the outer wall and a water-intrusion preventive wall extending forward from the end of the rear wall to surround the corresponding portion of the outer wall, and a mating female connector housing including a hollow columnar portion adapted to be inserted into the cavity to compress the packing thereby completing a watertight joint. In the connector, the packing is formed with an engaging projection extending from its end surface opposed by the rear wall of the male connector housing, and the rear wall is formed with a mating aperture to be engaged watertight by the engaging projection of the packing.
