Abstract:
1. A socket for mounting an electronic component, comprising: a socket housing including an electronic component accommodating part that is surrounded by a peripheral wall raised from four side parts of a quadrangle-shape bottom plate; a plurality of contacts protruding from the bottom plate of the socket housing and including elastic contact pieces that elastically contact a plurality of terminal parts in a bottom part of an electronic component in the electronic component accommodating part which is electrically connectable to the socket housing; and socket-side engaging parts provided at a plurality of places on the peripheral wall of the socket housing, wherein the socket-side engaging parts protrude from the peripheral wall of the socket housing to engage with electronic-component-side engaging parts of an electronic component insertable into the electronic component accommodating part to prevent coming-off of the electronic component, wherein the socket-side engaging parts engage with the electronic-component-side engaging parts to thereby prevent the electronic component from coming off the inside of the electronic component accommodating part, and wherein one or plural socket-side engaging parts of the socket-side engaging parts are arranged in each of two opposing side parts of the peripheral wall of the four side parts of the socket housing in positions that are not symmetrical with respect to a center of the electronic component accommodating part of the socket housing such that, in one side part of the two opposing side parts of the peripheral wall of the four side parts of the socket housing, plural socket-side engaging parts are arranged closer to both end sides thereof than to a center side thereof, with an interval in between the plural socket-side engaging parts, and in the remaining other side part, one or plural socket-side engaging parts are arranged closer to a center side thereof than to end sides thereof, and thereby, when the electronic component is inserted in a direction other than a specified orientation, the socket-side engaging parts are not matched to the electronic-component-side engaging parts.
