Publication number: 20120322288Abstract: An electrical connector includes an insulating body and a plurality of terminals assembled in the insulating body. The terminal has a fastening strip of which a bottom end is bent towards one side of the fastening strip and then protrudes rearward to form a soldering portion. A top end of the fastening strip is bent towards the other side of the fastening strip and then extends forward to form a first contact portion which has a front end thereof arched upward to project out of the insulating body for electrically connecting with one circuit. A second contact portion is formed at a substantial middle of a front edge of the fastening strip and further exposed outside the insulating body for electrically connecting with another circuit.Type: ApplicationFiled: June 15, 2011Publication date: December 20, 2012Applicant: CHENG UEI PRECISION INDUSTRY CO., LTD.Inventors: RONG-QIN LAN, LI-JUN XU

Patent number: 8281484Abstract: A pick-up jig is adapted to be dismountably mounted to an electronic component which has two buckling blocks. The pick-up jig includes a pick-up board and two buckling arms. The pick-up board is against a top of the electronic component. The pick-up board has a flat top surface for the convenience of the pick-up jig being picked up by a SMT machine. The two buckling arms perpendicularly extend downward from two opposite ends of a bottom surface of the pick-up board. An inside of each of the buckling arms protrude inward to form two blocking pillars spaced from each other to define a fastening groove therebetween. A buckling hook is protruded at a bottom of the buckling arm. The buckling blocks slide over the corresponding buckling hooks to be buckled in the corresponding fastening grooves and the buckling hook grappling a bottom of the corresponding buckling block.Type: GrantFiled: December 28, 2010Date of Patent: October 9, 2012Assignee: Cheng UEI Precision Industry Co., Ltd.Inventors: Rong-Qin Lan, Li-Jun Xu

Patent number: 8262414Abstract: A connector includes an insulating housing, terminals assembled in the insulating housing, a first shell having a receiving space surrounded by a top plate, two lateral plates and a bottom plate for receiving the insulating housing therein, and a second shell having a base board electrically fixed on the top plate. Two sides of the top plate define two first openings spaced from each other and communicating with the receiving space. A rear side of each first opening extends forward to form an elastic arm with a free end arched downward into the receiving space. Two sides of the base board define two second openings corresponding to the first openings. A rear side of each second opening protrudes forward to form an extending arm resting against a top of the elastic arm for strengthening insertion and extraction strength of the elastic arms acting on a plug connector.Type: GrantFiled: February 24, 2011Date of Patent: September 11, 2012Assignee: Cheng Uei Precision Industry Co., Ltd.Inventors: Jiang Li, Ming-Han Lin, Li-Jun Xu

Patent number: 8092244Abstract: An electrical connector includes an insulating housing with a plurality of terminals disposed therein, a buckling part, and a locking element. The insulating housing has a receiving chamber penetrating through a rear thereof. The insulating housing defines two buckling grooves with rears thereof being narrower than fronts thereof, and two fixing grooves connecting with insides of the buckling grooves. The buckling part is inserted in the buckling groove, and has a base arm, a contact arm and a fixing arm having a greater width than that of the base arm to be buckled in the front of the buckling groove. The locking element is inserted in the fixing groove, and has a base board resisting against the fixing arm, a fastening portion and a hook grappling an inside of the fixing groove. The fastening portion is located between the inside of the fixing groove and the fixing arm.Type: GrantFiled: December 28, 2010Date of Patent: January 10, 2012Assignee: Cheng Uei Precision Industry Co., Ltd.Inventors: Rong-Qin Lan, Li-Jun Xu, Ming-Han Lin
