Patent number: 7040910Abstract: A plug type connector, and more particularly a plug type connector having a locking function when the plug type connector is connected to a counter connector, coupling the plug type connector to the counter connector. A locking member is formed by a slender by a slender locking piece configured from a synthetic resin molded product, the operation load which is required for flexurally deforming the locking piece can be increasingly or decreasingly adjusted. The plug type connector comprises contact portions, the locking piece, a press operating member, and a backup member. The backup member has the function of adjusting the level of the operation load of the locking piece. In another embodiment, even when the locking member is made of metal, the enclosure of the counter connector is not shaved by a prying force applied on the counter connector, and hence the stability of the locked state can be enhanced.Type: GrantFiled: July 23, 2002Date of Patent: May 9, 2006Assignee: Hosiden CorporationInventors: Takayuki Nagata, Yasuo Nakai, Akihito Shichida

Publication number: 20030027450Abstract: The invention relates to a plug type connector, and more particularly to a plug type connector having a locking function of, when the connector is connected to a counter connector, coupling the connector to the counter connector. In the case where a locking member is formed by a slender locking piece 30 configured by a synthetic resin molded product, the operation load which is required for flexurally deforming the locking piece 30 can be increasingly or decreasingly adjusted. The plug type connector A of the invention comprises contact portions 20, the locking piece 30, a press operating member 50, and a backup member 60. The backup member 60 has a function of adjusting the level of the operation load of the locking piece 30. In another invention, even when the locking member is made of a metal, the enclosure of the counter connector is not shaved by a prying force applied on the counter connector, and hence the stability of the locked state can be enhanced.Type: ApplicationFiled: July 23, 2002Publication date: February 6, 2003Applicant: Hosiden CorporationInventors: Takayuki Nagata, Yasuo Nakai, Akihito Shichida

Patent number: 6270380Abstract: The invention relates to a multipolar electrical connector, and more particularly to a multipolar electrical connector that, as a counter connector 90, uses a single-head plug having a pole shaft 91 in which center poles are disposed in plural positions in the axial direction, respectively (hereinafter, referred to merely as “multipolar connector”). In the invention, plural predetermined contact pieces are incorporated into the body 10, so that plural poles are ensured by the predetermined contact pieces. In the invention, a required number of first additional contact pieces 40 and second additional contact pieces 50 are placed on the outer and inner peripheral sides of the boss portion 30, so that two or more poles are ensured by the additional contact pieces 40 and 50. According to the invention, therefore, the number of poles is increased by that of poles which are formed by the additional contact pieces.Type: GrantFiled: August 1, 2000Date of Patent: August 7, 2001Assignee: Hosiden CorporationInventors: Akihito Shichida, Yutaka Uno

Patent number: 5679013Abstract: An open/close type connector having a base member, a cover member, and an electronic apparatus of a card type or a personal computer type using the connector. The connector is thin so that when it is not used, i.e., is not connected with a modular plug the portability of the card is not lost. In addition, less restriction is introduced on the attachment position at which the connector is attached to the card or the personal computer. A link is used for opening and closing the cover member. Structure for enhancing the stability and the electrical connection reliability when a modular plug is mounted on the connector is provided, and the base member and the cover member are adapted to be rotatable so that they can be relatively opened or closed thereby yielding a connector which can be preferably adopted by an electronic apparatus of a card type.Type: GrantFiled: August 28, 1995Date of Patent: October 21, 1997Assignees: International Business Machines Corporation, Ricoh Company, Ltd., Hosiden CorporationInventors: Katsuya Matsunaga, Katsuhisa Yamamoto, Akihito Shichida

Patent number: 5022872Abstract: In a jack which has in its body a tip contact piece for engagement with a tip electrode of a plug when the plug is inserted into the jack body through its plug insertion hole, the tip contact piece is a U-shaped metal piece whose two legs form first and second contact pieces for gripping therebetween the tip electrode of the plug. The first contact piece is longer than the second one and its forward end is inwardly convexed to form an engaging protrusion for engagement with the neck of the tip electrode. The engaging protrusion extends into the plug insertion hole to a depth of about 20% of its inner diameter. When the plug is inserted into the jack body, a forward contact portion of the second contact piece resiliently contacts the crest of the tip electrode after the latter has moved past the engaging protrusion of the first contact piece.Type: GrantFiled: June 27, 1990Date of Patent: June 11, 1991Assignee: Hosiden Electronics Co., Ltd.Inventor: Akihito Shichida

Patent number: 4957454Abstract: A pin jack, an electric connector element having a bored hole to receive a pin plug, is improved to have flexible adaptability in light of the size of openings to be formed on a terminal plate. Normally audio class pin jacks are non-coaxial, but radio level or higher frequency class pin connectors are of coaxial cable formation. These different kinds of connectors need openings with different diameters which lead to terminal plates having mixed size openings in order to meet mixed mountings. This difficulty is solved by rendering a inventive pin jack with two different concentric mounting diameters, of which a larger one of the diameters, which may be referred to as jacket ring, is externally formed to cover a portion of a cylindrical extension and is to be integrally connected to a cubic body base.Type: GrantFiled: September 21, 1988Date of Patent: September 18, 1990Assignee: Hosiden Electronic Co., Ltd.Inventor: Akihito Shichida
