Patent number: 8992245Abstract: A connector comprises a housing extending in a front-rear direction and a sealing member attached in the housing. The housing has a rear wall located at a rear end portion of the housing and an enclosed portion extending from the rear wall in the front-rear direction. When the housing is formed by a molding process, a metal mold is used to form a plurality of seal stoppers around the enclosed portion. Each of the seal stoppers protrudes from the enclosed portion in a direction perpendicular to the front-rear direction. The housing has a plurality of holes which are formed when the metal mold is removed from the housing. Each of the holes pierces the rear wall in the front-rear direction. The holes face the respective seal stoppers in the front-rear direction. The sealing member is attached to the enclosed portion so as to be located between the rear wall and the seal stoppers in the front-rear direction. The front sides of the holes are covered by the sealing member.Type: GrantFiled: October 20, 2011Date of Patent: March 31, 2015Assignee: Japan Aviation Electronics Industry, LimitedInventors: Koji Higuchi, Osamu Hashiguchi, Yoshinori Mizusawa

Patent number: 4887974Abstract: A top housing, which has formed therein arrays of first housing chambers and first pin insertion holes respectively communicating therewith, and a bottom housing, which has formed therein arrays of second housing chambers and second pin insertion holes respectively communicating therewith, are assembled together so that the corresponding first and second housing chambers intercommunicate. A socket contactor is housed across the corresponding first and second housing chambers. The top and bottom housings are held together by a frame so that they are slidable relative to each other. Terminal pins of an IC are inserted into the first housing chambers through the first pin insertion holes and pin conductors of a printed board are inserted into the second housing chambers through the second pin insertion holes. By sliding the top and bottom housings relative to each other, each socket contactor is bent, and by its spring force, the socket contactor is urged against the terminal pin and the pin conductor.Type: GrantFiled: January 27, 1989Date of Patent: December 19, 1989Assignees: Japan Aviation Electronics Industry, Limited, NEC CorporationInventors: Yoshiaki Ichimura, Katumi Takegawa, Yoshinori Mizusawa, Mitsuo Komoto, Shoji Umesato
