The lock is composed of two parallel fillets, one of rubber or other elastic material, and the other of more rigid material, e.g. metal forming a unit with that elastic. In the assembled state, the rubber fillet locates under pressure against the edge of the printed circuit. Each gable piece is provided partly with hook-shaped end parts which can engage in recesses in the magazine gables, and partly with a hole in which the lock beam can be inserted. The gable pieces are each provided also with a retention screw which engages in a deepened formation in the fillet of rigid material. When the printed circuit is fitted into the magazine, and pushed inwards against the magazine rear plate, the lock beam is inserted in the holes of the gable pieces, and pushed towards the magazine. The hook-shaped end parts are engaged in the recesses so that the lock beam locates against the printed circuit edge. |
