  • Device for inserting and extracting circuit modules with dual-in-line leads
    Patent number: 4461073
    Abstract: A hand-operated device 10 is disclosed for inserting or extracting the dual-in-line leads (14) of a circuit module (12), particularly of the type having a relatively fragile circuit-supporting substrate (18), into or out of respective lead-engaging through-holes of a circuit board (17), or a board-mounted socket. The device (10) comprises a pair of mutually disposed, longitudinally extending, and spring-biased gripping jaws (21, 22), interconnected by a spaced pair of guide rods (26, 27). Each guide rod is fixedly secured at one end within a bore (24a or b) of one jaw-supported boss (24), with the other end being slidably received within an aligned bore (29a or b) of an other jaw-supported boss (29) so as to allow precisely controlled, relative linear displacement of the jaws.
