摘要： A chip carrier socket (2, 102) has a latching chip (30, 130) which extends across a recess (10, 110) of the chip carrier socket (2, 102) to maintain a chip carrier (22, 122) positioned in the recess (10, 110). The latching chip (30, 130) is mounted to the chip carrier socket (2, 102) in a manner which allows the latching chip (30, 130) to move between an open and a closed position. The latching chip (30, 130) is configured to cooperate with the chip carrier socket (2, 102) such that the latching chip (30, 130) is prevented from being accidentally removed from the chip carrier socket (2, 102) during the operation thereof, thereby eliminating the possibility of the latching chip (30, 130) making electrical contact with other circuitry provided in the area. An overstress member (170) is provided on the latching clip (130) to insure that the latching chip will be reliable over many cycles.

摘要： A tool (20) cooperates with a chip carrier socket (10) to insert and/or remove a chip carrier (2) therefrom. In operation, the tool (20) is positioned in alignment with the socket (10), the chip carrier (2), and a cover (32). The tool (20) is actuated, causing the engagement means (56, 58) to pivot about the pins (102). This pivoting action causes shoulders (94) to engage a respective surface of the chip carrier socket (10) or the chip carrier (2). Movable frame means (59) are provided on the tool (20). The movable frame means (59) being movable from a first position to a second position, such that when the frame means (59) is provided in the first position, the shoulders (94) engage the chip carrier socket (10) to insert the chip carrier (2) therein. When the movable frame means (59) is in the second position, the shoulders (94) engage the chip carrier (2) to extract the chip carrier (2) from the chip carrier socket (10).

摘要： An extraction tool (2) for removing circuit boards (4) from connectors (6) comprises printed circuit board retaining channels (52, 52') for frictionally engaging the circuit board (4) and camming member (54, 54') for cooperation with latching arm (18) of the connector (6). The tool (2) is made from two body portions (20, 22), the body portions (20, 22) being movable with respect to each other, enabling the tool (2) to compensate for various sizes of circuit boards (4). As the tool (2) is inserted onto the circuit board (4), channels (52, 52') provided in legs (46, 46') of the tool (2) frictionally engage edges of the circuit board (4). As insertion continues, the camming arms (54, 54') engage the latching arms (18) of the connector (6), thereby moving the latching arms (18) from the circuit board (4). With the latching arms (18) disengaged from the board (4), the tool (2) is retracted. The frictional engagement between the channels (52) and the edges of the board (4) causes the board (4) to be removed as the tool (2) is retracted. The operation of the tool (2) provided for the easy removal of the circuit board (4) from the connector (6), even when the connectors (6) are closely spaced together.
