Description

The IC-card connector

Technical field

The utility model refers to a kind of IC-card plant that supplies especially relevant for a kind of IC-card connector, can reduce manufacturing cost, and not scratch chip, makes the more effective IC-card connector in location.

Background technology

See also Fig. 1 and Fig. 2, it is a kind of known IC-card connector, this IC-card connector 10a can be inserted in wherein for IC-card 30a (as Fig. 3) such as smart card or SIM (subscriber identity module) cards, this IC-card connector 10a can be arranged on the circuit board, makes this IC-card 30a reach electric connection by this IC-card connector 10a and circuit board.

This IC-card connector 10a includes an insulating base frame 11a, most individual contact terminal 12a and a sliding seat 13a, these contact terminals 12a is arranged in two rows and each most of row (as four), the welding ends 14a of these contact terminals 12a stretches out forward and backward two sides of insulating base frame 11a, and the contact jaw 15a of these contact terminals 12a then stretches into insulating base frame 11a inside.

On this insulating base frame 11a, be provided with two slide rail 16a in addition, this sliding seat 13a left and right two breaks away and is actively tied on the two slide rail 16a, make this sliding seat 13a do forward and backward moving along slide rail 16a guiding, this sliding seat 13a be provided with most with the corresponding slotted eye 17a of the contact jaw 15a of contact terminal 12a.

When this IC-card 30a is plugged on the sliding seat 13a, and drive this sliding seat 13a and move forward to when location, the contact jaw 15a of these contact terminals 12a beginning projects upwards in slotted eye 17a, and contacts with the chip 31a of IC-card 30a, to prevent the IC-card 30a chip 31a that weares and teares when inserting.

Be provided with a spring 18a in addition on this insulating base frame 11a, the end of this spring 18a contacts sliding seat 13a front end, can bestow the strength that resets that sliding seat 13a moves backward.
