Publication number: 20040016562Abstract: A harness protector for accommodating a wire harness in a protector main body in a curved shape includes a friction member for holding the wire harness in the accommodating state temporarily. The friction member abuts resiliently on the wire harness. The harness protector is provided on a sliding member or a fixed member. The wire harness is wired from the harness protector to the sliding member and the fixed member. The friction member temporarily prevents the wire harness from being removed while the sliding member moves. An spring member for biasing the wire harness in a direction where the wire harness is accommodated is provided in the harness protector. The wire harness compresses the spring member to the maximum at a first moving end of the sliding member. The friction member is disposed a position so as not to interfere with a restoring of the spring member during moving the sliding member from the first moving end to a second moving end.Type: ApplicationFiled: July 10, 2003Publication date: January 29, 2004Applicant: YAZAKI CORPORATIONInventors: Tohru Aoki, Tsukasa Sekino, Mitsunori Tsunoda

Patent number: 4951716Abstract: A locking mechanism has an engagement hole formed in each side portion of a lid, an engagement projection formed on each side wall of a body for engagement with a corresponding engagement hole, holding plates disposed on a lid portion so as to hold the corresponding engagement projections toward the engagement holes in the adjacent side portions, and projections projecting from the edge surfaces of the respective side walls for engagement with corresponding holes formed in the lid portion. If a force acting to open the lid is externally applied, forces acting to press the engagement projections toward the corresponding engagement holes act upon the edge portions of the respective projections which project from the edge surfaces of the respective side walls of the body. Accordingly, the body and the lid can be made to positively lock into each other.Type: GrantFiled: December 2, 1988Date of Patent: August 28, 1990Assignee: Yazaki CorporationInventors: Mitsunori Tsunoda, Norihiro Yoneyama

Patent number: 4403155Abstract: An improved wiring system is provided in which a connector box having a plurality of terminals, electrical circuitry, and bus bars is incorporated. Since each bus bar provides forked conductive paths between the circuitry and the terminals, the terminals of the connector box and outside connectors can be connected by way of wires in a one-to-one correspondence. This simplified wiring mode greatly reduces manual labor in the manufacture of wire harnesses. Moreover, if a plurality of connector boxes of such structure as above are provided, they can be arranged in the vicinity of any of the electrical equipment of the vehicle due to their compact structure, thus minimizing the arrangement of power line wires in the car body.Type: GrantFiled: January 25, 1982Date of Patent: September 6, 1983Assignee: Yazaki CorporationInventors: Hideto Aoki, Tomoyuki Hirano, Mitsugu Watanabe, Toshiyuki Kamano, Mitsunori Tsunoda, Toshikazu Akiyama, Mitsuyasu Kanehiro, Mitsuji Kubota, Masayuki Sato
