Patent number: 6783380Abstract: An insertion-force reducing connector assembly and method for mating multi-terminal male and female connectors of the type used in automotive wiring harnesses. The female connector is movably retained in a frame-like holder by a self-actuating force reducing link that automatically couples a male connector inserted into the holder to the female connector with an insertion/withdrawal ratio in which the female connector moves away from the male connector in the terminal-mating direction more slowly than the male connector is inserted, thus allowing the connectors to be coupled over a longer than normal terminal-mating distance and reducing the insertion force needed to mate the terminals. The method includes the steps of coupling the female connector to the holder and subsequently mating the male connector to the female connector in the holder.Type: GrantFiled: June 11, 2003Date of Patent: August 31, 2004Assignee: Yazaki North America, Inc.Inventors: Shashidhar M. Kamath, Bryan D. Cole, David Kwang

Patent number: 6783381Abstract: A waterproof connector consists of a female housing 2 and a male housing 3 which are to be coupled with other. The male housing 3 includes a body 15 accommodating female terminals, a cover 15 and a packing 39. The cover 23 includes a plurality of peripheral walls 24 and a wall 50. The wall 50 has a recess 52. A protrusion 53a is provided at the inner edge of the recess 52 close to a packing 39. The protrusion 53a protrudes from the inner edge of the recess 52 close to the packing 39 toward the female housing. The protrusion 53a is arranged between the recess 52 and packing 39. The one end 39a of the packing 39 is located between the protrusion 53a and the body 15. In this configuration, the waterproof connector can prevent water from permeating into a contact portion between terminal metal fittings.Type: GrantFiled: October 21, 2002Date of Patent: August 31, 2004Assignee: Yazaki CorporationInventor: Eiji Fukuda

Patent number: 6783382Abstract: A housing carries a male push-lock precision BNC connector. The function of the BNC latch of the male connector carried therein is performed by a spring-biased lock ring captive in a housing and that fits snugly and concentrically over a male sleeve, resulting in a double shell of two rigidly attached cylindrical portions that are coaxial, coextensive, yet separated to accept a BNC female shell. The double shell is held captive by anchoring it to the inside of the housing. The male sleeve has a slot and/or cut-away portion to accept the forward travel of the bayonet pins, which, when the connector halves are engaging, extend beyond the thickness of the sleeve and into the region occupied by the lock ring. The lock ring has grooves having various portions that engage the bayonet pins. As the housing containing these male parts is without rotation moved toward the female connector, the lock ring rotates as the grooves contact the bayonet pins.Type: GrantFiled: October 29, 2002Date of Patent: August 31, 2004Assignee: Agilent Technologies, Inc.Inventor: Jimmie D Felps

Patent number: 6783383Abstract: A light socket with a terminal cover and lamp lock is disclosed. This single, molded piece is resiliently attached to the top lip of the socket and is held, cantilevered, over the central terminal. Screwing the lamp into the socket, displaces the cover and lock into a gap formed in the socket threads. Pressure of the resilient lock laterally against the lamp base helps to hold the lamp in place. Contacts that electrically connect the central terminal and line wire conductor and the lamp base and the neutral wire are both formed with lower portions shaped like inverted “Vs” that slice perpendicularly into the insulation to capture their respective conductors in the crotch of the V to assure good contact regardless of whether the conductors are centered in their insulation.Type: GrantFiled: February 25, 2003Date of Patent: August 31, 2004Inventor: James W. Gibboney

Patent number: 6783384Abstract: An electrical connector (1) for receiving an electrical card (2) therein. The connector includes an insulative housing (11), and a plurality of conductive terminals (18) received in the housing. The housing includes a beam (12), and a pair of parallel guiding arms (13) extending in a same direction from opposite ends of the beam respectively. A reinforcing plate (16) interconnects the guiding arms to prevent the guiding arms from bending inwardly when the connector becomes heated during use. A middle portion (162) of the reinforcing plate is offset outwardly from the housing. When the connector becomes heated during use, the reinforcing plate bends inwardly. However, space beneath the reinforcing plate is still sufficient to ensure that the reinforcing plate does not contact the received electrical card, and that the electrical card can be freely inserted into or removed from the connector.Type: GrantFiled: February 11, 2003Date of Patent: August 31, 2004Assignee: Hon Hai Precision Ind. Co., Ltd.Inventor: Dong Di Wu

Patent number: 6783385Abstract: An electrical connector includes a housing holding a contact. The housing has an opening configured to receive a wire to be joined with the contact. The electrical connector includes a clamping member held within the housing. The clamping member is movable between clamped and unclamped states. The electrical connector includes an actuator movably held within the housing. The actuator moves between open and closed positions. The actuator has a clamp seating portion that holds the clamping member in the unclamped state.Type: GrantFiled: February 5, 2003Date of Patent: August 31, 2004Assignee: Tyco Electronics CorporationInventor: William J.

Patent number: 6783386Abstract: A strain relief device for an electrical connector designed to be interconnected to another connector of the same type to connect cables containing at least one twisted pair for the transmission of very high-frequency differential data signals. Conductors are connected in a connection block by insulation displacement contacts to contact blades, adapted to ensure contact in an interface block with the corresponding contact blades of the other connector. The device has two guillotines sliding in side grooves of the connection block. The side edges of the guillotines form a 90° angle between them and a 45° angle in relation to the direction of movement during the clamping operation, such that the side edges of the guillotines form a diaphragm when they approach one another, thereby ensuring a 360° seal preventing the cable from being deformed or damaged.Type: GrantFiled: June 4, 2003Date of Patent: August 31, 2004Assignee: International Business Machines CorporationInventor: Jean-Yves Clement

Patent number: 6783388Abstract: A connector has two housings (10, 30). When the two housings (10, 30) properly connected, movable detectors (25) are at standby positions and do not interfere with an edge of a mount hole (H). Thus, the two housings (10, 30) can be mounted into the mount hole (H). On the other hand, with the two housings (10, 30) partly connected, the movable detectors (25) are displaced to interfering positions and interfere with the edge of the mount hole (H). Thus a partly connected state of the two housings (10, 30) can be detected.Type: GrantFiled: May 21, 2002Date of Patent: August 31, 2004Assignee: Sumitomo Wiring Systems, Ltd.Inventor: Yasuo Matsushita
