Patent number: 5873737Abstract: A male connector (B) includes an outer housing (10) equipped with a rotatable lever (31) and an inner connector (20) which moves in an axial direction in the outer housing by rotation of the lever. A female connector (A) includes a shell for receiving the male connector; the male and female connectors having abutting faces (36 and 4) abutting on each other by magnetic force when the inner connector (20) and the female connector (A) are engaged with each other, at least one of the abutting faces being made of magnet (35). The male and female connectors can constitute a provisional locking structure before substantial magnetic adsorption force due to proximity of the male and female connectors. The male and female connectors are coupled to each other to connect terminals mounted in the male and female connectors to each other. Even if a strong magnet is used to couple relatively large connectors with each other, they can be separated by small force.Type: GrantFiled: February 13, 1997Date of Patent: February 23, 1999Assignee: Yazaki CorporationInventors: Shigemi Hashizawa, Shigeo Mori, Toshiyuki Sekimori, Yasuyoshi Fukao
