Socket for electrical parts

An apparatus comprising:

• a plurality of contact pins respectively corresponding to a plurality of terminals of an electrical part, each contact pin comprising a pair of elastic pieces having a closed position in which the pair of elastic pieces electrically contact the corresponding terminal, and an opened position in which the pair of elastic pieces do not electrically contact the terminal, a respective elastic piece of the pair being elastically deformed to thereby move in a displacement direction to thereby change between the opened and closed positions, wherein
• when in the opened position, a respective elastic piece of the pair and an elastic piece of an adjacent contact pin appear overlapped in a horizontal sectional view which is orthogonal to the displacement direction, and are substantially adjacent to each other along a perpendicular to the displacement direction.

A socket for an electrical part, comprising:

• a socket body;
• a plurality of contact pins on the socket body and respectively corresponding to a plurality of terminals of an electrical part, each contact pin comprising a pair of elastic pieces having a closed position in which the pair of elastic pieces electrically contact the corresponding terminal, and an opened position in which the pair of elastic pieces do not electrically contact the terminal, a respective elastic piece of the pair being elastically deformed to thereby move in a displacement direction to thereby change between the opened and closed positions,
• wherein, when in the opened position, a respective elastic piece of the pair and an elastic piece of an adjacent contact pin appear overlapped in a horizontal sectional view which is orthogonal to the displacement direction, and are substantially adjacent to each other along a perpendicular to the displacement direction.

An apparatus comprising:

• and
• means for arranging the plurality of contact pins with respect to each other so that, when a respective pair of elastic pieces is in the opened position, a respective elastic piece of the pair and an elastic piece of an adjacent contact pin appear overlapped in a horizontal sectional view which is orthogonal to the displacement direction, and are substantially adjacent to each other along a perpendicular to the displacement direction.

An apparatus comprising:

• a plurality of adjacent contact pins respectively corresponding to a plurality of terminals of an electrical part, each contact pin comprising a pair of elastic pieces having a dosed position in which the pair of elastic pieces electrically contact the corresponding terminal, and an opened position in which the pair of elastic pieces do not electrically contact the terminal, a respective elastic piece of the pair being elastically deformed to thereby move in a displacement direction to thereby change between the opened and closed positions, wherein
• when in the opened position, a respective elastic piece of the pair and an elastic piece of an opened pair of an adjacent contact pin appear overlapped in a horizontal sectional view which is orthogonal to the displacement direction, and are substantially adjacent to each other along a perpendicular to the displacement direction.
