  • Publication number: 20090042423
    Abstract: Slide members in the lever-type connector are respectively provided with resilient latch arms and respectively have latching projections that latch on the corresponding drive projections during the temporary mating with the mating connector. Each of the resilient latch arms is formed between a pair of slits respectively extending from specified points which are located in the end portion of one of the cam grooves toward the corresponding entrance where the corresponding drive projection enters and on the side opposite from the side of the entry of the corresponding drive projection so as to undergo elastic deformation in the direction of thickness of the slide member.

  • Patent number: 7137835
    Abstract: A lever type connector on a housing and a lever thereof a locking mechanism that locks the lever in the final position. The locking mechanism has a housing-side locking arm that extends substantially along the pivoting track of the lever from the side of the initial position of the housing to the side of the final position and underneath this pivoting track, and a lever-side locking arm that is provided on the lever and that extends in the direction opposite from the direction of extension of the housing-side locking arm. The lever-side locking arm has a lock release on the upper side of the free end thereof, and also has a locking part that locks with the housing-side locking arm underneath the lock release.

  • Patent number: 7121895
    Abstract: The present invention provides a female connector that can simplify the process of attaching male contacts by eliminating the need for the process of removing some of male contacts. The female connector has a female housing with recessed mating sections for receiving mating male connectors. A plurality of rows of male contacts protrude from the respective bottom surfaces of the recessed mating sections of the female housing to the interior portions of the recessed mating sections. Ribs protrude from the respective bottom surfaces of the recessed mating sections to the interior portions of the recessed mating sections with the protruding length from these bottom surfaces being greater than that of the male contacts. The ribs are provided in areas where the male contacts are arranged, and male contact receiving cavities that receive some of the male contacts are formed in the ribs.

  • Patent number: 7114991
    Abstract: A waterproof connector sealing member has a plurality of electrical wire insertion holes that extend between the two main surfaces of a flat plate-shaped sealing main body. A plurality of projecting ribs are provided on the inner wall surface of each of the electrical wire insertion holes, and the projecting ribs of respectively adjacent electrical wire insertion holes are provided in different positions with respect to each other along the axial direction of the electrical wire insertion holes. Relief grooves are formed in the sealing main body in positions adjacent to the electrical wire insertion holes in the vicinity of the outer edges of this sealing main body, with each of these relief grooves extending from one of the main surfaces that is closer to the projecting rib of the adjacent electrical wire insertion hole provided toward the outside in the axial direction.

  • Patent number: 6030252
    Abstract: A waterproof connector which makes it possible to extend wires from a housing at a narrow pitch while waterproofing the wires, and which makes it possible to obtain a highly-reliable waterproofing effect, and a waterproofing-housing member which is used in the waterproof connector. The waterproof connector (10) has a housing (20) and a waterproofing-housing member (30). The waterproofing-housing member (30) includes an inner member (33) and outer members (31, 32) which are formed as integral members of the inner member (33) via hinge members (41, 42). The inner member (33) and outer members (31, 32) are formed so that the members are capable of engaging with each other. When the waterproofing-housing member (30) is engaged on a rear side of the housing (20), the waterproofing-housing member (30) is fastened to the housing (20) while a space between the waterproofing-housing member (30) and the housing (20) is waterproofed; at the same time, the wires (100) are waterproofed and extend rearward.

  • Patent number: 5967849
    Abstract: A plurality of wires 4 are linearly disposed along the direction of length of a long slender insulating support 2, and contacts 6 are formed as terminals on both ends of each wire. The contacts 6 are symmetrically disposed on the outer periphery of the long slender insulating support 2 while being prevented from slipping out by means of checking engagement parts or shoulders 21 which are provided at both ends of the long slender insulating support 2, and which prevent slipping out in the direction of length. Frame-form bodies or caps 8 are disposed on the outer peripheries of the contacts 6 so that these frame-form bodies 8 engage with all of the plurality of contacts 6 and the contacts 6 abnd caps 8 can shift axially to facilitate connedction to another component.
