SIM card connector with locking arrangement
View Patent ↗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.
1. A SIM (Subscriber Identity Module) card connector of substantially rectangular, comprising:
an insulative base 1 on an either side thereof including an L-shaped groove 111 on a rear corner, a recess 12 extended from an intermediate portion to a front end and having a rear shoulder 121 , an intermediate protrusion 13 , a tab 122 between the rear shoulder 121 and the protrusion 13 , and a front protuberance 122 , and a stop member 14 extended from a rear end of the protuberance 122 and disposed perpendicular to the protuberance 122 ;
a cover 2 including two side flanges 23 each including a pin 21 on a rear corner slidably fitted in and confined by the groove 111 to form a pivot, a rear and a front openings 24 , a rear and a front flexible fastening members 25 each being parallel with the adjacent opening 24 , and an intermediate tongue 22 ; and
a plurality of parallel conductors 3 on a bottom of the base 1 ;
whereby pivoting the cover 2 about the pins 21 to cover the base 1 will cause either rear fastening member 25 to urge against a portion of the recess 12 between the rear shoulder 121 and the protuberance 122 , either tongue 22 to fit between the tab 122 and the protrusion 13 , and either front fastening member 25 to urge against a portion of the recess 12 between the protrusion 13 and both the stop member 14 and protuberance 122 ; and
whereby sliding the cover 2 forward will interlock the cover 2 and the base 1 by moving either pin 21 forward from a bending point of the groove 111 until being stopped by a forward end of the groove 111 with either rear fastening member 25 being urged against the protuberance 122 , either tongue 22 being stopped by the protrusion 13 , and either front fastening member 25 being securely engaged with both the stop member 14 and protuberance 122 after passing the stop member 14 .
2. The SIM card connector of claim 1 , wherein the fastening member 25 is a gable.
3. The SIM card connector of claim 1 , wherein the shoulder 121 is a ramp.
