Holes in the presser frame through which the metal frames are exposed permit the metal frames to act as a static electricity discharging device.

Abstract: 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 retaining claws 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 with the retaining claws. In this manner, the group of contacts can be arrayed on the base member.

The operating member has a first cam portion engagable with the contacts in such a manner as to be able to move contacting portions of the contacts upwardly away from the leads and a second cam portion engagable with the contacts in such a manner as to thereafter move the contacting portions laterally away from the leads, the first cam portion acting on the contacts prior to the second cam portion.

Abstract: An insulating layer is formed on at least one side surface of a spring portion of a contact, and a contacting portion formed on the spring portion is made narrower than the thickness of the spring portion, and a contacting surface of the contacting portion spaced from an edge portion of the insulating layer inwardly of the side surfaces of the spring portion.

Abstract: An electrical conductive pattern is deposited on the surface of a frame constituting an integrated circuit carrier. To enable leads extending from an integrated circuit package to come in contact with the electrical conductive pattern, a plurality of first contact portions are formed on the inner end of the electrical conductive pattern. In addition, to enable a plurality of contact pieces extending from an integrated circuit socket to come in contact with the conductive pattern, a plurality of second contact portions are formed on the outer end of the electrical conductive pattern. Thus, the leads extending from the integrated circuit package are reliably brought into electrical contact with the contact pieces via the first contact portions, the electrical conductive pattern and the second contact portions. The arrangement of the electrical conductive pattern in that way makes it possible that the leads can be spaced from each other at an interval smaller than an interval between adjacent contact pieces.

Abstract: A contact of an electric part socket has a first spring portion, a second spring portion spaced apart from the first spring portion but connected to it at both basal and distal ends thereof, a terminal portion leading to the connecting portion between the basal ends and adapted to be brought into contact with a wiring board or the like, and a contact portion formed on the connecting portion between the distal ends and adapted to be brought into contact with a terminal of an electric part to be engaged on it. The first and second spring portions are flexed about the connecting portion between the basal ends in order to displace the contact portion downward. The contact portion is pressure contacted with the terminal of the electric part mounted on it by reaction of the first and second spring portions.

Abstract: An elastic pressure member is disposed between adjacent first elastic contacts arranged on a base member such that the elastic pressure member corresponds to second contacts arranged on a cover member. Parts of the plurality of leads arranged on an electric part are given contact pressure by elasticity of the first contacts, and the remainder of the leads are given contact pressure against the second contacts by elasticity of the elastic pressure member.

Abstract: A socket for an electric part has a socket body, and the socket body has a push-up spring for exerting an upward force to an electric part. A group of push-down contacts operated to be placed in pressure contact with a group of terminals of the electric part exert downward forces on the terminal. The downward forces of the push-down contacts are set to be larger than the upward force of the push-up spring. The push-down contacts, when placed in pressure contact with the terminals of the electric part, push down the terminals of the electric part while biasing the push-up spring and slidedly moving along the surfaces of the terminals of the electric part.

Abstract: To remove a contact condition between a contact and a lead of an IC package, a movable plate is moved forwardly from a control position to a release position by pivoting a crank lever, which includes a crank shaft portion having an eccentric shaft portion, from a starting point to a terminal point. The starting point of the forward pivotal movement of the eccentric shaft portion of the crank shaft portion is set in a third or fourth quadrant of a rectangular coordinate system with its origin at the rotation axis of the crank shaft portion (i.e. the starting point of the central axis of the eccentric shaft portion is disposed below the rotation axis of the crank shaft portion).
