  • Publication number: 20070224890
    Abstract: A contact is mounted in a battery connector of an electronic device and has a soldering section, a body section, a resilient section, two inclined gaps and a contacting section. The body section extends from the soldering section and has a first end and a second end. The resilient section extends from the body section and has a first end, a second end and a tapered segment. The first end of the resilient section is connected to the second end of the body section. The tapered segment is tapered toward the first end of the resilient section. The inclined gaps are defined in the second end of the body section to form the tapered segment. The contacting segment extends from the second end of the resilient section. With the inclined gaps, the contact is compact, resilient and has a low material cost.

  • Patent number: 7220148
    Abstract: A SIM card connector includes an insulative base including on its either side an L-shaped rear groove, a recess including a rear ramp, an intermediate protrusion, a tab between the rear ramp and the protrusion, and a front protuberance, and a front stop member; a cover including two side flanges each including a rear pin slidably fitted in and confined by the groove to form a pivot, rear and front gables, and an intermediate tongue; and conductors on a bottom of the base. Sliding the cover forward will interlock the cover and the base by moving either pin to a forward end of the groove with either rear fastening member being urged against the protuberance, either tongue being stopped by the protrusion, and either front fastening member being securely engaged with both the stop member and protuberance after passing the stop member.
