Publication number: 20090142952Abstract: A conversion adapter ring for a connector has a female screw, on the inner periphery of a cylindrical main body thereof for screwing and mounting onto a male screw of a screw coupling type connector. A bayonet groove is also provided on the outer periphery of the main body for engaging a bayonet coupling type connector. An alternate connector is a connector capable of being inserted into and extracted from a mating connector in the axial direction. The connector has, in the outer periphery of a cylindrical shell that mates with the mating connector, a male screw for engaging the mating connector, and a bayonet groove formed with a notch in the male screw.Type: ApplicationFiled: February 21, 2006Publication date: June 4, 2009Inventor: Junya Akasaka

Patent number: 6984137Abstract: The invention provides an electrical connector assembly that is constituted by a first connector and a second connector, each of the first and second connectors having signal contacts disposed in two rows, a grounding member disposed between the rows of signal contacts and a housing that holds the signal contacts and the grounding member and being engaged with each other, and an electrical connector that constitutes the electrical connector assembly. The electrical connector and electrical connector assembly increase the reliability of a grounding path, require only a small number of component parts and are suitable for high-speed signal transmission. A first grounding plate and a second grounding plate that constitute the grounding member are disposed in the immediate vicinity of rows of signal contacts that are disposed in two rows and the housing has a through opening. Therefore, a connection section that constitutes the grounding member can be visually checked.Type: GrantFiled: December 21, 2004Date of Patent: January 10, 2006Assignee: Tyco Electronics AMP K.K.Inventors: Junya Akasaka, Izumi Hasegawa

Publication number: 20050142922Abstract: An electrical connector assembly comprises a first connector and a second connector. The first connector and the second connector each have a housing with a contact receiving wall. Contacts are disposed in the housings of the first and second connectors. Each of the contacts has a contact portion, a terminal, a convex projection, and a press-fit portion. The convex projection is arranged between the contact portion and the press-fit portion. The convex projection abuts the contact receiving wall in the housing in which the contact is disposed to space the contact from the contact receiving wall when the first and second connectors are mated. A protective lip is formed on the contact receiving walls of the first and second connectors. The protective lip is formed adjacent to the contact portions of the contacts.Type: ApplicationFiled: December 16, 2004Publication date: June 30, 2005Inventors: Junya Akasaka, Izumi Hasegawa

Patent number: 6910901Abstract: A card connector assembly is capable of preventing extraction of cards of varying dimensions and shapes. The card connector assembly is constructed of a connector and a box for housing the connector. A first plate that moves horizontally by operation of a slider, first and second cam protrusions that cam engage the first plate, and a second plate positioned above the first plate are provided in the box. When the slider is moved rightward, the first plate engages the second cam protrusions and rises, to press the second plate upward. An elastic rubber piece is adhesively attached to the second plate. The elastic rubber piece frictionally contacts a lower main surface of a card to prevent extraction thereof.Type: GrantFiled: July 17, 2003Date of Patent: June 28, 2005Assignees: Tyco Electronics AMP K.K., Fanuc Ltd.Inventors: Junya Akasaka, Hiroyuki Suwa

Patent number: 6878000Abstract: A connector is provided to reduce the risk of erroneous ejection of a card from a card connector during use thereof. A stopper member is rotatably mounted on a knob of an ejecting mechanism. The stopper member is urged in the counterclockwise direction by a spring. When the knob protrudes in a state in which the card is not inserted in the connector, the stopper member, urged by the spring, exits a slot of the knob, rotates about a pin, and a rear end of the stopper member enters a card receiving slot. Accordingly, a card cannot be inserted into the card receiving slot 3 due to the protrusion of the stopper member into the card receiving slot.Type: GrantFiled: July 17, 2003Date of Patent: April 12, 2005Assignees: Tyco Electronics AMP K.K., Fanuc Ltd.Inventors: Junya Akasaka, Hiroyuki Suwa

Patent number: 6544044Abstract: The present invention relates to a BGA package IC socket that accommodates a BGA (ball grid array) package such that the BGA package IC socket has high reliability and can withstand long-term use. The socket is equipped with package receiving members 140. Package receiving parts 141 of members 140 receive the portions of the BGA package 10 located in the vicinity of the opposite edges of the undersurface of the BGA package 10. The parts 141 pivot downward with the insertion of the BGA package 10. The parts 141 have a shaft which are supported on the housing so that the package receiving members 140 are free to pivot. Springs 150 cooperate with the members 140, such that the springs 150 resist the insertion of the BGA package into the socket.Type: GrantFiled: August 3, 2001Date of Patent: April 8, 2003Assignee: Tyco Electronics, AMP, K.K.Inventor: Junya Akasaka
