  • Publication number: 20170146568
    Abstract: An electronic test equipment is adapted to test an electronic component. The electronic component has a circuit body and a plurality of connectors that are electrically connected to the circuit body. The electronic test equipment includes a metallic test seat and a plurality of spring probes. The metallic test seat is adapted to support the circuit body thereon, and is formed with a plurality of spaced-apart probe holes extending therethrough and possessing diameters that are substantially the same. Each of the probe holes is adapted to receive a corresponding one of the connectors. The spring probes are respectively and entirely positioned within the probe holes, and are adapted to electrically contact the connectors.

  • Patent number: 7367816
    Abstract: An electrical connector assembly includes a socket connector soldered on one circuit board and a plug connector soldered on another circuit board. The socket connector includes an insulating socket base and a plurality of first terminals received in the first terminal-receiving slots of the insulating socket base. Each first terminal successively extends to form a first terminal lead, a first inverted U-shaped portion, a base U-shaped portion and an auxiliary-clamping portion. One leg of the base U-shaped portion includes a first elastic-contact portion. The plug connector includes an insulating plug base and a plurality of second terminals received in the second terminal-receiving slots of the insulating plug base. Each second terminal successively extends to form a second terminal lead and a second inverted U-shaped portion having a second elastic-contact portion.

  • Patent number: 6409529
    Abstract: A Subscriber Identity Module connector (1) includes an insulative housing (10) having a front and a rear rows of recesses (11), a plurality of terminals (20) retained in the recesses with contact portions (21) extending beyond a top surface of the housing for being horizontally exerted on by a SIM card (40), and a grounding pin (30) retained in a front portion of the recess of the rear row with a transitional portion (311) extending upwardly and forwardly beyond the top surface of the housing for being horizontally exerted on by the SIM card. During insertion, a SIM card slides on the grounding pin and exerts horizontal force on the transitional portion of the grounding pin to form the working circuit after the contact pads of the card fully engage with the contact portions of the terminals.
