Socket for mounting an electronic device

A socket comprising:

• (a) a base member,
• (b) a cover member movably mounted on the base member toward and away from the base member,
• (c) a plurality of contacts, each of which has an elastic deformed portion between a first end fixed to the base member and a movable second end, the contact having an engagement part a selected distance from the movable second end,
• (d) a contact regulating member having a plurality of slots at locations corresponding to said plurality of contacts on the base member, a stop surface formed in each said slot for engagement with a respective engagement part so that the movable second ends of the plurality of contacts have a selected protrusion height from the contact regulating means,
• (e) an adaptor movable toward and away from the contact regulating member between opposite extremities proximate to and removed from the contact regulating member, the adaptor having a seating surface, a spring member disposed between the adaptor and the contact regulating member urging the adaptor toward the removed extremity, a plurality of through-holes formed through the adaptor at locations corresponding to the slots of said contact regulating means, the plurality of through-holes serving to guide the movable second ends of the plurality of contacts respectively, and
• (f) a latch member linked between the cover member and the base member being engageable with a semiconductor device received on the seating surface to press down and move the adaptor toward the contact regulating means from the extremity removed from the contact regulating member to the extremity proximate to the contact regulating member.

A socket comprising:

• (b) a cover member movably mounted on the base member toward and away from the base member,
• (c) a plurality of contacts each of which has an elastic deformed portion between a first end fixed to the base member and a movable second end,
• (d) an adaptor movable toward and away from the base member between opposite extremities proximate to and removed from the base member, the adaptor having a seating surface and a plurality of through-holes through the adaptor and the seating surface at locations corresponding to the contacts,
• (e) at least one latch member linked between the cover member and the base member and being engageable with a semiconductor device received on the seating surface to press down and move the adaptor toward the contacts,
• the latch member rotatable in linkage with movement of the cover member, the latch member being movable in a first segment of motion between a retracted position when the cover is proximate to the base member and a position in which the pressing part of the latch member is engageable with a semiconductor device disposed on the seating surface with the latch member rotating using a first fulcrum in the first segment of motion and in a second segment of motion between the position in which the pressing part of the latch member is engageable with a semiconductor and a position in which the adaptor is at the extremity proximate to the base member, the latch member rotating using a second different fulcrum in the second segment of motion.
