Patent number: 8333619Abstract: A connector according to the invention includes an insulative body, and a first contact and a second contact that are disposed in the body at different height levels from each other, the first contact or the second contact being elastically deformable. The first contact includes an mismatched portion having an higher impedance than that of another portion of the first contact. The second contact includes an adjusting portion to be brought close to the mismatched portion by elastic deformation of the first contact or the second contact in a direction close to the second contact or the first contact.Type: GrantFiled: November 19, 2009Date of Patent: December 18, 2012Assignee: Hosiden CorporationInventors: Hayato Kondo, Toshiharu Miyoshi

Publication number: 20110244730Abstract: A connector, and printed circuit board foot pattern for a connector which can efficiently transmit a high-speed differential signal are provided. In a connector 1, a contact group 30 includes at least paired adjacent signal contacts SC-SC, and non-paired contacts GC which are placed on both adjacent sides or one adjacent side of the paired signal contacts. The contacts are arranged so that the distance W1 between the paired signal contacts SC-SC is shorter than the distance W2 between adjacent signal and non-paired contacts SC-GC, thereby enhancing the differential coupling force between the paired signal contacts SC-SC.Type: ApplicationFiled: March 29, 2011Publication date: October 6, 2011Applicant: HOSIDEN CORPORATIONInventors: Hayato Kondo, Toshiharu Miyoshi

Patent number: 7967641Abstract: It is an object of the invention to provide a connector in which a plurality of stationary contacts 5 are arranged on an insulator 3, a plurality of cantilevered movable contacts 8 are arranged in rear of the stationary contacts while tip end sides are placed in a front side, and, even when at least one specific stationary contact 5b of the stationary contacts 5 and at least one specific movable contact 8b of the movable contacts 8 are arranged in substantially one row in a state where the specific contacts are anteroposteriorly close to each other, tip end portions of all of the movable contacts can be engaged with the insulator.Type: GrantFiled: July 17, 2009Date of Patent: June 28, 2011Assignee: Hosiden CorporationInventor: Toshiharu Miyoshi

Patent number: 7824221Abstract: The invention provides a connector in which, while miniaturization and thinning are attained at a level equivalent to the conventional art, it is possible to prevent a phenomenon that molten solder drips from a wire connecting portion to form a solder bridge between adjacent contacts, from occurring, and a cable can be soldered to the wire connecting portion with excellent workability and high strength. In the connector of the invention, each of terminal portions (25) of plural contacts (20) which are juxtaposed in the pitch direction has a wire connecting portion (26, 27, 28) to which a lead wire (71, 72, 73, 74) drawn out from a cable (70) is to be soldered. The wire connecting portion is expansively opened along the connector thickness direction which is perpendicular to: an insertion/extraction direction of the connector with respect to a counter connector; and the pitch direction perpendicular to the insertion/extraction direction.Type: GrantFiled: June 12, 2008Date of Patent: November 2, 2010Assignee: Hosiden CorporationInventor: Toshiharu Miyoshi

Patent number: 7824222Abstract: The invention provides a connector in which, in an over-mold process, it is possible to prevent a molten resin from flowing through inevitable gaps (88, 89) of a shell (80) into the inside of the shell, thereby preventing problems such as that movable portions of contacts (20) become immovable, from arising. The connector of the invention has a plug body (10) in which contacts (20) to be connected to a cable (70) are held by an insulative body (40), the body (40) is shielded by a shell (80) formed by a metal plate, and a part of the plug body (10) is over-molded. The body (40) has sealing portions (41, 42) which are fitted into gaps (88, 89) of the shell (80) to close the gaps (88, 89).Type: GrantFiled: June 12, 2008Date of Patent: November 2, 2010Assignee: Hosiden CorporationInventors: Toshiharu Miyoshi, Kenji Miki

Patent number: 7806704Abstract: The present invention provides a connector including an insulative body; a first differential signaling contact, disposed inside the body; a second differential signaling contact, disposed inside the body in spaced relation to and at an equal height level to the first differential contact; and a third contact, disposed inside the body, at a different height level from the differential signaling contacts, and positioned between the differential signaling contacts and offset toward one of the differential signaling contacts. The third contact includes a first overlapping portion that overlaps in plane position with the first differential signaling contact; and a second overlapping portion that overlaps in plane position with the second differential signaling contact.Type: GrantFiled: June 11, 2009Date of Patent: October 5, 2010Assignee: Hosiden CorporationInventors: Toshiharu Miyoshi, Hayato Kondo

Publication number: 20100248515Abstract: A connector has a first contact and first signal contacts, and a second contact and second signal contacts arrayed at a different height. All the contacts have connection portions arranged at the same height position. The connection portion of the first contact is located between the connection portions of the second signal contacts and the connection portion of the second contact is located between the connection portions of the first signal contacts. A distance B is larger than a distance A. The distance A is a distance between the connection portion of the first signal contact and the connection portion of the second contact and also a distance between the connection portion of the second signal contact and the connection portion of the first contact. The distance B is a distance between the connecting portion of the first signal contact and an adjacent connection portion of the second signal contact.Type: ApplicationFiled: March 1, 2010Publication date: September 30, 2010Applicant: HOSIDEN CORPORATIONInventors: Hayato KONDO, Yutaka MASUMOTO, Toshiharu MIYOSHI
