Catch attachment to retain SIM block on circuit board

摘要

The catch attachment (6) retains the SIM block on a circuit board (2) which is fitted with a corresp. attachment point (7). The SIM block has a housing (13) containing a torsion bar (25). The catch attachment (6), torsion bar (25) and catch hook locate with the attachment point (7) on the circuit board (2).The torsion bar (25) is constructed through a slit in the housing (13) and allows for the spring operation of the catch. It is positioned outside the cross-section (9) of the circuit board (2). The catch attachment (6) has insertion guides (20,21).
