A plurality of pinholes arranged on the socket provide a plug-in function for a plurality of pins of an IC device. A conductive holder placed in the pinhole is a single element made integrally by bending a metallic piece. The holder includes: an extension part arranged along the extension direction of pin-hole, a holding part located at the top end of the extension part, and an electrical connection part located at the bottom end of the extension part. The electrical connection part is a hollow structure having an accommodation inner space. The electrical connection part has a pouring opening so that the hollow structure may be filled with resin.Type: GrantFiled: October 7, 2003Date of Patent: August 16, 2005Assignee: VIA Technologies, Inc.Inventors: Moriss Kung, Kwun-Yao Ho

Patent number: 6926540Abstract: A module assembly includes a module cover including a bottom wall, a front wall, a rear wall and two opposite side walls defining a receiving cavity therebetween, an electrical connector and a printed circuit board both received in the receiving cavity and a cover member covering the receiving cavity. The module cover has a mating portion with a mating space defined therein. The front wall defines passageways communicating with the receiving cavity and the mating space. The connector includes an insulating housing and a number of terminals retained in the housing. Each terminal includes an engaging portion extending beyond a front face of the housing into the mating space through a corresponding passageway and a press-tail extending upwardly beyond a top face of the housing. The printed circuit board defines plated through holes compliantly receiving the press-fit tails of the terminals.Type: GrantFiled: February 12, 2004Date of Patent: August 9, 2005Assignee: Hon Hai Precision Ind. Co., Ltd.Inventor: Eric D. Juntwait

Patent number: 6916210Abstract: A compressor is provided with a fluid tight electrical connector. The electrical connector is sealed against the seal compressor housing, and a cable end connector is detachably attached to a connector housing . Since the cable is separately attached to the connector housing, it is not directly connected to terminal pins in the compressor. This reduces damage to those terminal pins. Further, unique sealing arrangements make the electrical connection fluid tight.Type: GrantFiled: February 26, 2003Date of Patent: July 12, 2005Assignee: Carrier CorporationInventors: Billy W. Moore, Jr., Scott E. Westberg

Patent number: 6910904Abstract: A hermetically sealed compressor assembly including a housing, an electric motor located in the housing, a compression mechanism located in the housing and operatively coupled to the motor, and a terminal assembly comprising a cup-shaped terminal body and having electrically conductive pins extending therethrough. The cup-shaped terminal body extends through and is sealingly attached to the housing. A cluster block assembly is in communication with the terminal assembly and includes a cluster block fitted to the terminal body, the cluster block having free volume therein. The pins are electrically connected to the motor through the cluster block assembly. A cavity is defined between the interior of the cup-shaped terminal body and the cluster block, and a dielectric material substantially fills at least one of the cavity and the cluster block free volume.Type: GrantFiled: May 4, 2001Date of Patent: June 28, 2005Assignee: Tecumseh Products CompanyInventors: Todd W. Herrick, Rick L. Bunch

Patent number: 6876137Abstract: There is provided a low pressure discharge lamp, which comprises a discharge tube, a lamp base holding the discharge tube, and a base cap (6) for covering the lamp base. The base cap (6) also provides mechanical support to the discharge tube. The base cap (6) comprises tube openings (10) for receiving end parts of the discharge tube. The base cap (6) further comprises an adhesive space (14) adjacent to a tube opening (10), the adhesive space containing an amount of adhesive. The adhesive space (14) is open toward the discharge tube. The adhesive contained in the adhesive space (14) adheres to an end part of the discharge tube and thereby fixes the discharge tube to the base cap (6). The base cap comprises at least one upper transversal member (31) and at least one lower transversal member (32). The transversal members (31,32) extend substantially in a plane parallel to a plane of the tube opening (10) adjacent to the adhesive space (14).Type: GrantFiled: June 6, 2003Date of Patent: April 5, 2005Assignee: General Electric CompanyInventors: István Würsching, Erzsébet Cserteg, Zoltán Nagy, József Fülöp

Patent number: 6854996Abstract: A busbar assembly for electrically connecting a plurality of conductors includes a housing defining an interior cavity and first and second ports. The first and second ports each include a conductor passage and communicate with the interior cavity. The conductor passages are each adapted to receive a conductor therethrough. An electrically conductive busbar conductor member is disposed in the interior cavity. At least one holding mechanism is provided to selectively secure each of the conductors to the busbar conductor member for electrical contact therewith. Sealant is disposed in the conductor passages of each of the first and second ports. The sealant is adapted for insertion of the conductors therethrough such that the sealant provides a seal about the inserted conductors. The sealant may be a gel.Type: GrantFiled: December 20, 2002Date of Patent: February 15, 2005Assignee: Tyco Electronics CorporationInventors: Harry George Yaworski, Kenton Archibald Blue, Rudolf Robert Bukovnik

Patent number: 6835090Abstract: A sealed electrical assembly that includes a housing having an opening at an end. An electrical device is positioned in the housing. The electrical device includes a lead that extends out of the open end. A cover is positioned within the opening. The cover includes a plate portion and a tab portion spaced apart from the plate portion. The tab portion extends into a cutout in the housing that is located between the plate portion and the housing end to position the cover with respect to the housing. A sealant is disposed around a perimeter of the plate portion to provide a seal between the cover and the housing. A portion of the sealant is disposed in a space between the cutout and the plate portion to prevent leakage through the cutout.Type: GrantFiled: August 20, 2003Date of Patent: December 28, 2004Assignee: Delta Systems, Inc.Inventor: Michael Eric Liedtke

Patent number: 6823587Abstract: A method of making a data cable includes coupling an electrical conductor of an end of a cable to an electrical contact that is positioned within a portion of a connector housing. A protective clamp is positioned over a section of the cable rearwardly of the electrical contact. Another portion of the connector housing is formed over the cable section and the clamp, to thereby secure the cable with the connector housing. The protective clamp is positioned between the formed portion of the connector housing and the cable section and provides mechanical protection for the cable section to reduce damage thereto.Type: GrantFiled: August 5, 2002Date of Patent: November 30, 2004Assignee: Tensolite CompanyInventor: Bruce Reed
