Patent number: 9142932Abstract: An electrical connector having a fusible element for mounting on a substrate includes an insulative housing and a contact terminal retained in the insulative housing. The contact terminal includes a resilient contacting arm extending beyond a mating face of the insulative housing and a soldering portion for mating with the fusible element. A gelatinous flux is deployed on the fusible element, and/or on the soldering portion, and/or between the fusible element and the soldering portion, and then flux is dried to immovably fix the fusible element with respect to the soldering portion. The dried flux will be re-juvenile to clean and remove an oxidized layer originally existed on the soldering portion so as to achieve robust welding quality. Besides, a method for trimming an electrical connector to have robust welding properties is also disclosed.Type: GrantFiled: April 12, 2012Date of Patent: September 22, 2015Assignee: HON HAI PRECISION INDUSTRY CO., LTD.Inventors: Been-Yang Liaw, Chih-Pi Cheng, Fu-Jin Peng, Zhan-Jun Xu

Patent number: 7658632Abstract: An electrical connector (1) for electrically connecting an electronic package with a circuit substrate. The connector includes a housing (11), a fastening device assembled with the housing, and a stiffener (12) surrounding the housing. The stiffener includes a back end (123), and a pair of spaced first walls (125) adjoining the back end. Each first wall has a latch (128) extending upwardly therefrom, and then bends inwardly. The back end has a pair of spaced spring fingers (129) extending substantially horizontally, and then bends slightly upwardly. The latches are fastened to the housing for locating the housing in a vertical direction. The spring fingers abut against the housing for locating the housing in a horizontal direction. The stiffener reinforces the housing, and protects the housing from deformation or warpage.Type: GrantFiled: June 5, 2007Date of Patent: February 9, 2010Assignee: Hon Hai Precision Ind. Co., Ltd.Inventors: Zhan-Jun Xu, Fu-Jin Peng, Ming-Yong Chen

Patent number: 7641496Abstract: An electrical connector (1) of the present invention includes an insulative base (10) defining a plurality of passageways (101) to receive a plurality of conductive terminals (19) therein, a base plate (142) retained in the insulative base, a cover (12) movably assembled on the base, a cover plate (142) retained in the cover and a cylindrical actuator (16). The base defines a through hole (1021) thereof. The base plate defines a through hole (1421) and a guiding slot (1422). The cover defines a plurality of passages (124) corresponding to the passageways of the insulative base and a through hole (123). The cover plate defines a through hole (1411) and a guiding portion (1413) sliding in the guiding slot. The cylindrical actuator is received and rotating in said through holes. At least one inner edge of the through hole of the base plate extends outwards to form an edge portion with a smooth surface thereon.Type: GrantFiled: April 24, 2008Date of Patent: January 5, 2010Assignee: Hon Hai Precision Ind.

Publication number: 20070149016Abstract: An electrical connector assembly according to a preferred embodiment includes an electrical connector (1) and a pick up device (5) engageably mounted onto the electrical connector. The electrical connector includes a rear head portion, where an actuator (4) is rotatably held therein, and a front tail portion opposite to the head portion. The pick up device has a front covering portion (58) extending in a forward and downward direction relative to the front tail portion. Thus, during a SMT process used for soldering the electrical connector to a printed circuit board, temperature in difference is prevented between the head portion and the tail portion due to their different heat absorption characteristic, thereby avoiding solder wicking and/or bridging of the tail portion.Type: ApplicationFiled: December 26, 2006Publication date: June 28, 2007Inventors: Zhan-Jun Xu, Qing-Feng Wang, Fu-Jin Peng
