Patent number: 8992271Abstract: An electrical terminal is provided and includes a first member and a second member. The first member includes a pair of connecting face portions, a coupling portion, and a plurality of serrations. The pair of connecting face portions face each other in a substantially V shape such that a gap between inner faces of the pair of connecting face portions gradually becomes smaller from a wider-gap side to a narrower-gap side. The coupling portion connects the pair of connecting face portions at ends of the narrower-gap side of the inner faces. The plurality of serrations are disposed on the pair of inner faces and extend along intersecting directions. The second member has a substantially U shape that mates with the pair of connecting face portions and can displace outer side faces of the pair of connecting face portions inward to urge the inner faces closer to each other.Type: GrantFiled: July 31, 2013Date of Patent: March 31, 2015Assignee: Tyco Electronics Japan G.K.Inventors: Masaaki Harasawa, Ken Sakai

Patent number: 7153173Abstract: An electric connector is connected to a conductive part, e.g. an electric wire, of a first article, and is fitted onto the first article and/or a second article. The contact of the electric connector directly contacts a conductive part of the second article with a sufficient contact pressure. The electric connector includes a housing fitted onto at least one of the articles, and a contact provided on the housing and including a connecting part connected to the conductive part of the first article, a contacting point contacting the conductive part of the second article, and an elastic part, which undergoes elastic deformation when the contacting point is pressed. The housing and/or the contact has a holding member, which holds the elastic part in an elastically deformed condition in advance in the direction of pressing the contacting point and prevents the restoring movement thereof.Type: GrantFiled: May 23, 2003Date of Patent: December 26, 2006Assignee: J.S.T. Mfg. Co., Ltd.Inventors: Masaaki Harasawa, Saburou Kase, Satoru Kihara

Patent number: 7077705Abstract: A connector has a housing, a cover for covering the housing. The housing has a card retention section, a plurality of contacts, a swing slider, a lock mechanism. The card retention section has a card insertion port for accepting therein a memory card. The contacts face the card insertion port to electrically contact with a distal end side of the memory card. The swing slider is provided to freely swing to an insertion direction of the memory card, and engages with the distal end of the memory card to slide with the memory card in an insertion direction when the memory card is inserted into the card insertion port. The lock mechanism for swinging the swing slider toward inside engages the swing slider to a concave section of the memory card for retaining the memory card when the memory card reaches a proximal end side of the housing.Type: GrantFiled: August 19, 2004Date of Patent: July 18, 2006Assignee: J.S.T. Mfg. Co., Ltd.Inventor: Masaaki Harasawa

Publication number: 20060019506Abstract: A connector for connecting printed boards comprises contact terminals (40a-40x) where contact portions and board connection terminals are connected by spring bodies, a movable housing (20) for receiving the contact portions, and a fixing housing (30) to which the board connection terminals are fixed. Reinforcement pins (50a, 50b) are inserted through through-holes penetrating through the movable and fixing housings. The contact terminals (40a-40x) are installed in the movable and fixing housings, and both housings are connected by the spring bodies with a predetermined spacing between them. Because the reinforcement pins limit the movement direction of the movable housing, vertical shock force applied to the connector housings is smoothly absorbed.Type: ApplicationFiled: August 29, 2003Publication date: January 26, 2006Inventor: Masaaki Harasawa

Patent number: 6896522Abstract: A hinge connector comprising an insulative connector housing (10) having a predetermined shape, a through hole extending through the connector housing, a receiving chamber defined in the through hole, and an elastic contact member (30) having electric conductivity and a rotatable contact member (50) that are received in the receiving chamber, wherein the elastic contact member (30) is elastically contacted at one end thereof with the rotatable contact member (50), and projects at the other end out of the through hole to form an external contact. This hinge connector is mounted on the main body housing (90) of an electronic device, a circuit board (70) is connected to a cover body, and the contact member (50) is disposed to make rotation contact with the pattern on the circuit board. Such arrangement provides a hinge connector wherein the contact smoothly rotates even if the contact pressure on the circuit board is increased, and good contact can be maintained.Type: GrantFiled: August 1, 2002Date of Patent: May 24, 2005Assignee: J.S.T.
