  • Patent number: 8353730
    Abstract: A probe connector includes an insulating housing defining inserting passages each longitudinally penetrating therethrough with a blocking rib being protruded in a periphery inside thereof. A probe has a base board of which a front end has a contact head stretched forward out of the inserting passage, and a rear end has a resisting board extending downward from an end edge thereof and two blocking boards protruded downward from two side edges thereof for cooperating with the blocking rib to prevent the probe from sliding out of the inserting passage. A terminal has a base plate blocking a rear end of the inserting passage, and an elastic arm extending forward from a top of the base plate with a free end designed as a contact portion abutting against the base board. An elastic element is retractably located between the resisting board and the base plate.

  • Patent number: 8235729
    Abstract: A connector has an insulating housing of which two opposite ends extended frontward to form a pair of supporting arms, terminals mounted in the insulating housing having soldering portions projected out of a bottom of the insulating housing, and a positioning member. The positioning member has a base slice. A rear of a side edge the base slice is extended downward to form a holding slice movably received in a through slot recessed at the supporting arm. A front of the side edge of the base slice is extended downward and then bent perpendicularly to form a soldering slice. As the height between the base slice and the soldering slice is bigger than that of the supporting arm, the positioning member is capable of moving up-and-down to adjust the relative position between the soldering slice and the soldering portions of the terminals.

  • Patent number: 8202123
    Abstract: A connector includes an insulating housing, a plurality of terminals assembled in the insulating housing, and a shielding shell curved from a metal plate to show a substantially rectangular tubular shape with a receiving space therein. Two free ends of the metal plate are acted as a pair of jointing plates end-to-end jointed with each other. Two end edges of the jointing plates jointed together each have a portion bent downward beyond a level plane of the jointing plates and then extended overstride the joint of the jointing plates to form a reinforcing portion. The reinforcing portion of one jointing plate is superposed against a bottom face of the other jointing plate and further welded with the other jointing plate together to ensure the jointing plates firmly jointed with each other. The insulating housing with the terminals is inserted rearward in the receiving space of the shielding shell.

  • Patent number: 8052435
    Abstract: A connector soldered to a PCB has an insulating housing of which two opposite ends recessed to form a pair of receiving recesses, terminals mounted in the insulating housing having soldering portions projected out of a bottom of the insulating housing, a positioning member. The positioning member has a base slice received in the receiving recess, a side edge of the front of the base slice extending downward and then being bent perpendicularly to form a soldering slice located to be lower than the bottom of the base for being soldered with the PCB. As the thickness of the base slice is less than the height of the receiving recess, intervals are accordingly formed between the positioning member and the top and bottom sides of the receiving recess to achieve an up-and-down movement of the positioning member.
