Patent number: 6709296Abstract: The module-type connector according to the present invention defines the connectable connectors with a rigid supporting plate which extends along the connecting direction in order to make it easy to properly fit a male connector to a female connector. In the module-type connector, the contacting portions of the contacts that are shifted in the separation direction of the corresponding terminal with which the contacting portions contact are almost uniformly distributed. Further, the male connector that receives a preliminary load from different levels in the direction so that opposing elastic contacting portions are widened by engaging between the first end portion of each contact within a housing and the different levels of the housing, has at least a protruding portion that protrudes from the contacting surface of the plurality of contacts toward the contacting surface thereof and that is provided between contacts.Type: GrantFiled: May 24, 2002Date of Patent: March 23, 2004Assignees: Advantest Corporation, Tyco Electronics AMP K.K.Inventors: Kouichi Shiroyama, Toshihiro Ichihashi, Katsuhiko Namiki, Yoshimasa Ito, Hiroshi Sakata, Eiichiro Takemasa

Patent number: 6045408Abstract: The present invention provides an electrical contact which can be used in a board-mounted electrical connector and is capable of effecting resilient engagement with circuit pads on a circuit board. Electrical connector 10 has a plurality of electrical contacts 50 inside a housing 20. Each of the electrical contacts 50 has a first plate member 62 and a second plate member 63 which are formed by folding at one end on an engaging side. The first plate member 62 has a press-fitting section 53 and a resilient contact section 52 extending at an inclined angle. The second plate member 63 includes a pressing shoulder 66 used during press-fitting into a cavity of the housing. When the housing 20 is mounted on a circuit board, the contact sections 52 of the electrical contacts 50 flex resiliently at the bottom side of the housing 20, and termination sections 54 resiliently engage circuit pads on the circuit board.Type: GrantFiled: October 16, 1998Date of Patent: April 4, 2000Assignee: The Whitaker CorporationInventor: Eiichiro Takemasa
