Socket for electrical parts
A socket for an electrical part includes a socket body to which an electrical part is accommodated, the socket body having a base portion to which a number of contact pins and a movable member disposed to the socket body to be vertically movable. The movable member includes a movable member body disposed substantially horizontally and formed with the insertion holes into which contact pins are inserted, respectively, and a projection piece projecting upward from the movable member body. The projection piece has an upper surface to which a pressed surface is formed, and when the pressed surface is pressed, the movable member is lowered.
1. A socket for an electrical part comprising:
a socket body to which an electrical part is accommodated, the socket body having a base portion to which a plurality of contact pins, having elastic pieces, which are contacted to or separated from terminals of the electrical part, are arranged; and
a movable member disposed to the socket body above the base portion thereof to be vertically movable, deformation of the elastic pieces of the contact pins inserted into insertion holes formed to the movable member being performed in accordance with the vertical movement of the movable member, according to the deformation thereof, contact portions formed to the contact pins being opened or closed, said movable member including a movable member body disposed substantially horizontally and formed with the insertion holes into which the contact pins are inserted and a projection projecting upward from the movable member body, said projection having an upper surface to which a pressed surface is formed, wherein when the pressed surface is pressed, the movable member is lowered,
wherein the projection is formed from an outer peripheral edge portion of the movable member body, and an accommodation member in which the electrical part is accommodated is formed from the outer peripheral edge portion of the movable member body at a position inside the projection.
2. The socket for an electrical part according to claim 1 , wherein said pressed surface of the projection is formed so as to be along substantially a horizontal direction.
3. The socket for an electrical part according to claim 1 , wherein said accommodation member is provided with an engaging piece through which the accommodation member is detachably provided for the socket body.
4. The socket for an electrical part according to claim 1 , wherein said accommodation member is provided with a guide piece for guiding the electrical part when the electrical part is accommodated.
5. The socket for an electrical part according to claim 1 , further comprising an operation member mounted to the socket body to be vertically movable, said operation member being formed with a pressing surface pressing the pressed surface.
6. A socket for an electrical part comprising:
a socket body to which an electrical part is accommodated, the socket body having a base portion;
a plurality of contact pins arranged on the base portion, each contact pin having
a contact portion which can be closed to contact a corresponding terminal of the electrical part, and can be opened to separate from the corresponding terminal, and
an elastic portion which is deformable to open and close the contact portion;
a movable member including a movable member body disposed substantially horizontally and formed with a plurality of insertion holes corresponding, respectively, to the plurality of contact pins, wherein
the movable member is disposed above the base portion of the socket body to be vertically movable with respect to the socket body, and so that the vertical movement of the movable member causes each contact pin to be inserted in the corresponding insertion hole to thereby cause the elastic portion of the respective contact pin to be deformed and, according to the deformation, cause the contact portion of the respective contact pin to be opened or closed, and
the movable member includes a projection projecting upward from the movable member body and formed from an outer peripheral edge portion of the movable member body, the projection having an upper surface which, when pressed, causes the movable member to be vertically lowered which thereby causes the elastic portions of the contact pins to be deformed and, according to the deformation, causes the contact portions of the contact pins to be opened; and
an accommodation member formed from the outer peripheral edge portion of the movable member body at a position inside the projection, and accommodating the electrical part.
7. The socket for an electrical part according to claim 6 , wherein the upper surface of the projection has a pressed surface formed along substantially a horizontal direction and, when pressed, causes the movable member to be vertically lowered.
8. The socket for an electrical part according to claim 6 , wherein the accommodation member is provided with an engaging piece through which the accommodation member is detachably provided for the socket body.
9. The socket for an electrical part according to claim 6 , wherein the accommodation member is provided with a guide piece for guiding the electrical part when the electrical part is accommodated.
10. The socket for an electrical part according to claim 6 , wherein
the upper surface of the projection has a pressed surface which, when pressed, causes the movable member to be vertically lowered, and
the socket further comprises an operation member mounted to the socket body to be vertically movable, the operation member being formed with a pressing surface pressing the pressed surface.
11. The socket for an electrical part according to claim 6 , wherein, when the movable member is vertically moved upward, the elastic portions of the contact pins are thereby caused to be deformed which, according to the deformation, causes the contact portions of the contact pins to be closed.
