Socket for electronic components
View Patent ↗A socket for electronic components includes a case that includes through holes of which inner wall surfaces have conductivity, and a ground contact unit that is disposed in one of the through holes and is electrically connected to an inner wall surface of the through hole. The ground contact unit includes a holding member that holds a conductive member and is fixed in the through hole. The conductive member has elasticity, and includes an intermediate portion held by the holding member, an upper extension portion extending upward from the intermediate portion, and a lower extension portion extending downward from the intermediate portion. The lower extension portion includes a ground extension portion that comes into elastic contact with the inner wall surface of the through hole, a fixed portion that is fixed to a substrate, and an impact absorbing portion that is formed between the fixed portion and the intermediate portion.
1. A socket for electronic components comprising:
a case through which a plurality of through holes of which inner wall surfaces have conductivity in a vertical direction are formed so as to pass in the vertical direction; and
a ground contact unit that is disposed in at least one of the plurality of through holes, electrically connects an electronic component-side contact portion of an electronic component to a substrate-side contact portion of a substrate, and is electrically connected to an inner wall surface of the through hole at upper and lower portions of the through hole,
wherein the ground contact unit includes a holding member that is held in the through hole, and a conductive member that is held by the holding member,
the conductive member has elasticity, and includes an intermediate portion that is held by the holding member, an upper extension portion that extends upward from the intermediate portion, and a lower extension portion that extends downward from the intermediate portion, and
the lower extension portion includes a ground extension portion that comes into elastic contact with the inner wall surface of the through hole so as to be slidable on the inner wall surface of the through hole, a fixed portion that is fixed to the substrate-side contact portion, and an impact absorbing portion that is formed between the fixed portion and the intermediate portion so as to be curved.
2. The socket for electronic components according to claim 1 ,
wherein the ground extension portion extends so as to face the inner wall surface of the through hole from a position different from a position where the fixed portion is connected to the impact absorbing portion.
3. The socket for electronic components according to claim 1 ,
wherein one direction orthogonal to the vertical direction is defined as a lateral direction,
the ground extension portion includes first and second ground extension portions extending so as to face a pair of inner wall surfaces of the through hole, which are provided so as to face each other in the lateral direction, respectively, and
the first and second ground extension portions come into elastic contact with the inner wall surfaces of the through hole in opposite directions.
4. The socket for electronic components according to claim 3 ,
wherein a direction orthogonal to the vertical direction and the lateral direction is defined as a longitudinal direction,
the first ground extension portion extends in the longitudinal direction along the inner wall surface of the through hole and the second ground extension portion extends in the longitudinal direction along the inner wall surface of the through hole, and
the holding member is fixed in the through hole so that one end of the first ground extension portion in the longitudinal direction and the other end of the second ground extension portion in the longitudinal direction come into pressure contact with the inner wall surface of the through hole.
