Abstract
A socket for an electrical part comprises a socket body and a contact pin through which an electrical part having a terminal and a printed circuit board are electrically connected. The socket body is provided with a lower plate to be mounted to the printed circuit board and an upper plate which is disposed above the lower plate and on which the electrical part is mounted. The upper plate is exchanged with one having a seating portion of different height. A contact portion of the contact pin is also exchangeable with one having different shape or type.
Claims17
A socket for an electrical part comprising:
- a socket body;
- and
- a contact pin which is provided for the socket body and through which an electrical part having a terminal and a printed circuit board are electrically connected,
- said socket body having a lower plate to be mounted to the printed circuit board and an upper plate which is disposed on the lower plate and on which the electrical part is to be mounted, wherein said upper plate has a seating portion on which the electrical part is placed in a contacting manner,
- said lower plate and said upper plate being formed with a plurality of lower side through holes and a plurality of upper side through holes, respectively, the contact pin being inserted into a pair of the lower and the upper side through holes,
- said contact pin comprising:
- a first plunger electrically connected to the terminal of the electrical part,
- a second plunger electrically connected to the printed circuit board,
- a tubular member disposed between the first and the second plungers, and
- an elastic member, the elastic member and the tubular member being disposed between the first and the second plungers, the tubular member having an end portion detachably engaging with one of the first and the second plungers, and a portion slidably contacting with another one of the first and the second plungers,
- the elastic member urging the tubular member so that the tubular member can abut against one of the first and the second plungers, resulting in urging the first and the second plungers in opposite directions to each other.
A socket for an electrical part comprising:
- a socket body;
- and
- a contact pin which is provided for the socket body and through which an electrical part having a terminal and a printed circuit board are electrically connected,
- said socket body having a lower plate to be mounted on the printed circuit board and an upper plate which is disposed above the lower plate and on which the electrical part is mounted, wherein said upper plate has a seating portion on which the electrical part is placed in a contacting manner,
- said lower plate and said upper plate being formed with a plurality of lower side through holes and a plurality of upper side through holes, respectively, the contact pin being inserted into a pair of the lower side and the upper side through holes, said plurality of lower side through holes being formed in an arrangement range wider than that of the plurality of upper side through holes.
A method of assembling a socket for an electrical part comprising a socket body and a contact pin which is provided for the socket body and through which an electrical part having a terminal and a printed circuit board are electrically connected, said contact pin having an elastic member urging a plunger upward, said socket body having a lower plate to be mounted to the printed circuit board and an upper plate which is disposed on the lower plate and has a seating portion on which the electrical part is placed in a contacting manner, the method comprising:
- preparing a plurality of the upper plates with respect to the lower plate, each upper plate having the seating portion of a different height;
- selecting one of the upper plates in accordance with the electrical part to be tested so that a press-in amount becomes a predetermined same amount, the press-in amount being a distance between the seating portion and a lower portion of an electrical part body of the electrical part when the terminal is mounted on the first plunger and an external force is not applied on the electrical part from a press member;
- and
- assembling the selected upper plate detachably but immovably on the lower plate.
A socket for an electrical part comprising:
- a socket body;
- and
- a contact pin which is provided for the socket body and through which an electrical part having a terminal and a printed circuit board are electrically connected,
- said socket body having a lower plate to be mounted to the printed circuit board and an upper plate which is disposed above the lower plate and on which the electrical part is to be mounted, wherein said upper plate has a seating portion on which the electrical part is placed in a contacting manner,
- said lower plate and said upper plate being formed with a plurality of lower side through holes and a plurality of upper side through holes, respectively, the contact pin being inserted into a pair of the lower and the upper side through holes,
- said contact pin comprising:
- a first plunger electrically connected to the terminal of the electrical part,
- a second plunger electrically connected to the printed circuit board,
- a tubular member disposed between the first and the second plungers, and
- an elastic member disposed between the first and second plungers to urge the first and second plungers in opposite directions,
- said tubular member having an end portion detachably engaging with one of the first and the second plunger, and a portion sliding within the upper plate and contacting with another one of the first and the second plungers.
A socket for an electrical part comprising:
- a socket body;
- and
- a contact pin which is provided for the socket body and through which an electrical part having a terminal and a printed circuit board are electrically connected,
- the contact pin having a contact portion contacting the terminal, the contact portion being urged toward the electrical part and being movable against an urging force when the terminal abuts against the contact portion,
- said socket body having a lower plate to be mounted to the printed circuit board and an upper plate which is detachably but immovably disposed on the lower plate and on which the electrical part is to be mounted,
- said upper plate having a seating portion on which the electrical part is placed in a contacting manner,
- the upper plate being designed to be replaced with another upper plate having a press-in amount which is the same as the upper plate, the press-in amount being a distance between a position where the terminal is abutted against the contact portion of the contact pin and a position where the electrical part is abutted against the seating portion.
