Socket for electrical parts and method of assembling same

A socket for electrical parts comprising:

• a socket body to which an electrical part having a number of terminals are accommodated;
• a number of contact pins arranged to the socket body so as to accord with the arrangement of said terminals of the electrical part;
• an operation member disposed to the socket body to be vertically movable in an installed state;
• lever members provided for the socket body to be rotatable in association with the vertical movement of said operation member;
• and
• a movable member disposed to the socket body to be movable in accordance with the movement of the operation member through the lever members to thereby displace the contact pins so as to contact or separate the contact pins to or from the terminals of the electrical part,
• said socket body being formed with boss portions, said lever members being formed with base end portions which are fitted to the boss portions to be rotatable, and said socket body being formed with guide wall sections so as to guide side portions of the base end portions of the lever members to thereby prevent the lever members from coming off from the boss portions.
