Abstract
In a socket for an electrical part, an IC package is received in a socket body. A contact pin is provided for the socket body. The contact pin is formed with a movable contact piece having a movable side contact portion. The movable side contact portion is contacted to a terminal of the IC package and separated from the terminal. In the socket, in a state that the IC package is not received in the socket body, a bent portion is formed on a stationary side contact portion such as a mount portion of the stationary contact piece. The movable contact side portion is seated on the stationary side contact portion so that the movable side contact portion is adapted to be slid on the bent portion, thereby making longer a wiped width of the movable side contact portion.
Claims16
A socket for an electrical part comprising:
- a socket body in which the electrical part is received;
- a contact pin provided for the socket body and formed with a movable contact piece, said movable contact piece being provided with a first contact portion at one end thereof, said first contact portion being contacted to a terminal of the electrical part or separated therefrom, said terminal has one surface and a second surface opposite to the one surface, said first contact portion has one surface contacted to the one surface of the terminal or separated therefrom, said contact pin is provided with a stationary contact piece having a second contact portion at one end thereof, said second contact portion having one surface contacting to the second surface of the terminal;
- a mount portion formed on the one surface of the second contact portion, said mount portion with which, without the electrical part being received in the socket body, the first contact portion is engaged;
- and
- a curved surface formed on a part of the mount portion so that the first contact portion is adapted to be slid on the curved surface, the mount portion having a substantially plain surface in a portion other than the curved surface, thereby making longer a wiped width of the movable contact piece.

A socket for an electrical part comprising:
- a socket body in which an electrical part is received;
- a contact pin provided for the socket body and formed with a movable contact piece, said movable contact piece being provided with a first contact portion at one end thereof, said first contact portion being contacted to a terminal of the electrical part or separated therefrom;
- a mount portion of the contact pin with which, without the electrical part being received in the socket body, the first contact portion is engaged;
- and
- a convex surface formed on a substantially flat top surface of the mount portion on which the first contact portion of the movable contact piece is contacted so that the first contact portion is adapted to be slid on the convex surface, thereby making longer a wiped width of the movable contact piece.

A socket for an electrical part comprising:
- a socket body in which an elected part is received;
- a contact pin provided for the socket body and formed with a movable contact piece, said movable contact piece being provided with a first contact portion at one end thereof, said first contact portion being contacted to a terminal of the electrical part or separated therefrom;
- a mount portion of the contact pin disposed on the socket body, said mount portion engaged with, without the electrical part being received in the socket body, the first contact portion, said terminal has one surface and other surface opposite to the one surface, said first contact portion has one surface contacted to the one surface of the terminal or separated therefrom, said mount portion having a second contact portion thereon, said second contact portion having one surface contacting to the other surface of the terminal;
- and
- a convex or concave surface formed on a part of the substantially flat surface of the second contact portion so that the first contact portion is adapted to be slid on the convex or concave surface, thereby making longer a wiped width of the movable contact piece.
