摘要： A socket for an electric part has an electric part accommodating space, and a plurality of contacts arranged in parallel relation along at least two opposing sides of the space. Each of the contacts has a contact nose portion to be contacted with a contact of the electric part accommodated in the electric part accommodating space, and a spring portion for biasing the contact nose portion inwardly in order to obtain a contacting pressure with the contact of the electric part. The socket for an electric part also has a pivotable lever disposed along a row of contacts. One end of the pivotable lever is engaged with the contact and the other end is extended outwardly of the contact from the engaging portion. The pivotable lever is supported such as to be pivoted about an idle fulcrum. The pivotable lever, when its other end is pushed down, is pivoted about the idle fulcrum to permit the engaging portion to displace the contact nose of the contact outwardly against resiliency of the spring portion, so that the contact nose is separated away from the contact of the electric part.

摘要： A pivot shaft member 8 is disposed at a central portion of an IC platform 2, and a pivotal operation portion disposed at a head portion of the shaft member 8 is exposed on an upper surface side of the IC platform 2. The shaft member 8 and the IC platform 2 or a socket board 1 are connected with each other by cam means. The IC platform 2 is guided between a higher position and a lower position by a pivotal operation of the pivot shaft member 8 in order to adjust an IC supporting height.

摘要： In a connector having a group of contacts arrayed at narrow pitches on a base member, a contact fixture device is formed separately from the base member forming a connector body. The contact fixture device is provided with a retaining claw adapted to secure the fixture device to the base member. The contact fixture device is further provided with a presser portion disposed across a group of seat elements of the group of contacts. The presser portion is laid across the group of seat elements to urge the group of seat elements against a surface of the base member when the fixture device is secured to the base member through the retaining claw. By this, the group of contacts can be arrayed on the base member.

摘要： A socket for an electric part has an electric part accommodating space, and a plurality of contacts arranged in parallel relation along at least two opposing sides of the space. Each contacts has a contact arm portion to be contacted with a contact of the electric part accommodated in the electric part accommodating space under pressure, and a curved spring portion for biasing the contact arm portion inwardly in order to exert a pressure contacting force to the contact arm. The socket also has a pivotable lever vertically pivotably supported along a row of the contacts, an operating portion formed on one end of the pivotable lever and adapted to operate the pivotable lever upwardly and downwardly, and an acting portion formed on the other end thereof and adapted to exert an outward force to the contact. When the pivotable lever is pivoted downwardly by the operating portion, the acting portion displaces the contact arm portion of the contact outwardly against the resiliency of the spring portion so that the contact arm portion is separated away from the contact of the electric part.

摘要： A latch arm for engaging with a corner portion of an IC is pivotably supported on a corner portion of a base member of an IC carrier or IC socket. A spring element extends from a rear end of the latch arm, and is bent to accumulate resilient force when the latch arm is pivoted upwardly to remove engagement. Thus, the latch arm is pivoted in the engaging direction by the accumulated resilient force, in order to maintain engagement with the IC.

摘要： A connector has a first connector member and a second connector member. The first connector has a pair of left and right shutter members at its left and right side ends. Each of the left and right shutter members has an eject portion which presses the second connector to separate the first and second connectors in accordance with a pivotal movement of the shutter member. The eject portion has a pair of connector press portions which are exposedly projected along front and rear outer surfaces of the first connector. The connector press portion is able to press front and rear outer edge portions of a surface of the connector opposite the first connector.
