Patent number: 5800208Abstract: In a movable connector-mounting construction, a mounting hole is formed through a panel on which a movable connector is mounted, and a gap is formed between the edge of the mounting hole and the movable connector so as to allow displacement of the movable connector. Retaining arms are formed on an outer surface of a housing, and displaceably retain the movable connector on the edge of the mounting hole. A pair of protective ribs are formed on the outer surface of the housing, and are disposed respectively on opposite sides of each of the retaining arms, and project outwardly beyond the retaining arm. Notches are formed respectively in those portions of the edge of the mounting hole corresponding respectively to the protective ribs, and each of the notches is larger in size than the protective rib by an amount corresponding to the amount of displacement of the housing.Type: GrantFiled: July 24, 1996Date of Patent: September 1, 1998Assignee: Yazaki CorporationInventors: Shigeo Ishizuka, Isao Kameyama

Patent number: 5707259Abstract: A female terminal includes a hollow contact portion of a substantially quadrangular cross-section for receiving a male terminal through an opening formed in a front end thereof, so as to establish an electrical connection between the male terminal and the female terminal, and a resilient contact piece, formed in the hollow contact portion by folding a tip portion of the bottom plate portion of the hollow contact portion, for biasing the male terminal toward the roof plate portion of the hollow. The resilient contact piece has a first piece portion which extends from the front end of the hollow contact portion so as to be inclined upwards toward the roof plate portion. The female terminal also includes a plurality of protruding portions extending from the bottom plate portion toward the roof plate portion, for supporting thereon the first piece portion while maintaining the elastic deformation of the first piece portion when an excessive force is applied to the first piece portion.Type: GrantFiled: July 23, 1996Date of Patent: January 13, 1998Assignee: Yazaki CorporationInventors: Shigeo Ishizuka, Isao Kameyama

Patent number: 5162004Abstract: 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.Type: GrantFiled: July 9, 1991Date of Patent: November 10, 1992Assignee: Yazaki CorporationInventors: Katsutoshi Kuzuno, Shigeo Ishizuka, Kazuaki Sakurai

Patent number: 5129840Abstract: Long and short terminal lugs are installed in alternate slots formed in the connector housing. Each terminal lug consists of an electrical contact portion and a wire connecting portion connected together through an intermediate link portion. The wire connecting portion is larger in width than the electrical contact portion. The wire connecting portions of the long terminal lugs and those of the short terminal lugs are staggered from each other in the axial direction. The long terminal lugs each have a depressed intermediate link portion so that the wire connecting portions of the adjacent short terminal lugs positioned by the side of the depressed intermediate links of the long terminal lugs are given sufficient space and are not interfered with by the wire connecting portions of the adjacent long terminal lugs as in the conventional connectors. This construction allows reduction in the size of the connector housing.Type: GrantFiled: February 28, 1991Date of Patent: July 14, 1992Assignee: Yazaki CorporationInventors: Katsutoshi Kuzuno, Shigeo Ishizuka, Masayuki Yamamoto

Patent number: 5112244Abstract: A terminal connector to which an electrical wire having a conductor and an insulating cover surrounding the conductor is to be connected is disclosed. The terminal connector has a terminal body having an electrical connecting section to which a partner terminal is to be electrically connected and an electrical wire connecting section to which the electrical wire is to be connected, and a connecting member, which is separate from the terminal body, adapted to be mounted to the wire connecting section to establish electrical connection between the conductor of the electrical wire and the terminal body when the connecting member is mounted to the wire connecting section. The wire connecting section includes a base plate having opposite edges along the elongated direction of the terminal body and side walls integrally formed on the respective edge of the base plate.Type: GrantFiled: April 4, 1991Date of Patent: May 12, 1992Assignee: Yazaki CorporationInventors: Katsutoshi Kuzuno, Shigeo Ishizuka, Masayuki Yamamoto

Patent number: 5000698Abstract: Disclosed herein is a terminal connector to which an electrical wire having a conductor and an insulating cover surrounding the conductor, which comprises an electrical connecting section to which a partner member is electrically connected, an electrical wire connecting section to which the electrical wire is to be connected, and a connecting member adapted to be mounted to the wire connecting section for electrically connecting the conductor of the electrical wire to the wire connecting section during mounting the connecting member to the terminal connector. The connecting member is formed from a U-shaped plate-like conductive member having a recess in which the electrical wire is securedly connected. The U-shaped connecting member includes two leg portions each having a tip portion, and each of the tip portions of the leg portions of the connecting member has an inclined edge for cutting or stripping the insulating cover when the connecting member is mounted to the wire connecting section.Type: GrantFiled: October 11, 1989Date of Patent: March 19, 1991Assignee: Yazaki CorporationInventors: Katsutoshi Kuzuno, Shigeo Ishizuka, Masayuki Yamamoto

Patent number: 4973271Abstract: 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.Type: GrantFiled: January 5, 1990Date of Patent: November 27, 1990Assignee: Yazaki CorporationInventors: Shigeo Ishizuka, Katsutoshi Kuzuno, Kazuaki Sakurai

Patent number: 4969831Abstract: A connector comprising a housing having terminal insertion chambers in a jacket body, a terminal connecting shaft which is rotatably mounted between the terminal insertion chambers and so mounted through as to be operable from the outside of the jacket body, and electrically-conductive terminal connecting members disposed on the terminal connecting shaft in the terminal insertion chambers; and a plurality of connectors having terminals disposed in terminal holding chambers open to the outside. The terminals, in the terminal insertion chambers, face each other over the terminal connecting member when the connector is joined to the housing, and are connected to each other by rotating the terminal connecting shaft.Type: GrantFiled: April 11, 1989Date of Patent: November 13, 1990Assignee: Yazaki CorporationInventors: Katsutoshi Kuzuno, Shigeo Ishizuka, Hiroshi Watanabe
