Abstract
Abstract A socket for an electric part comprises a socket body for connecting an electric part, a movable plate having a plurality of terminal insertion holes formed therein and being adapted to move along an upper surface of the socket body, a plurality of contacts in the socket body, and a no-load insertion space formed alongside each contact and adapted to facilitate a no-load insertion of a terminal of the electric part. The terminal of the electric part can be inserted into the no-load insertion space through the terminal insertion hole formed in the movable plate. The terminal can then be brought to a position in which it contacts the contact from the no-load insertion space by causing the movable plate to move laterally in one direction. Likewise, the terminal can be moved into the no-load insertion space from the contacting position by causing lateral movement of the movable plate in the other direction, in order to realize a no-load insertion and withdrawal of the electric part. The socket for the electric part further includes a member for normally urging the movable plate in the no-load insertion and withdrawal position direction so as to correctly align the no-load insertion space with the terminal insertion hole. The urging member is disposed, either directly or indirectly between the socket body and the movable plate.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
243 words
A socket for receiving at least one terminal of an electrical part, comprising: a socket body having at least one electrical contact mounted therein and at least one no-load insertion space formed adjacent said at least one contact, respectively; a movable plate having at least one terminal insertion hole formed therethrough, and being slidably mounted on said socket body for slidable movement between a no-load insertion position in which said at least one terminal insertion hole is aligned with said at least one no-load insertion space, respectively, so as to allow the at least one terminal to be respectively inserted through said at least one terminal insertion hole and into said at least one no-load insertion space without encountering resistance from said at least one contact, and a contacting position in which said at least one terminal insertion hole is misaligned with respect to said at least one no-load insertion space, respectively, and in which, when said at least one terminal is inserted through said at least one terminal insertion hole, said at least one terminal is engaged with said at least one contact, respectively; and biasing means for continuously urging said movable plate toward said no-load insertion position with a force insufficient to disengage the at least one terminal from said at least one contact but sufficient to move said plate into said no-load insertion position when the at least one terminal is not engaged with said at least one contact, respectively.
Claim 2
Dependent Claim
243 words
A socket for receiving at least one terminal of an electrical part, comprising: a socket body having at least one electrical contact mounted therein and at least one no-load insertion space formed adjacent said at least one contact, respectively; a movable plate having at least one terminal insertion hole formed therethrough, and being slidably mounted on said socket body for slidable movement between a no-load insertion position in which said at least one terminal insertion hole is aligned with said at least one no-load insertion space, respectively, so as to allow the at least one terminal to be respectively inserted through said at least one terminal insertion hole and into said at least one no-load insertion space without encountering resistance from said at least one contact, and a contacting position in which said at least one terminal insertion hole is misaligned with respect to said at least one no-load insertion space, respectively, and in which, when said at least one terminal is inserted through said at least one terminal insertion hole, said at least one terminal is engaged with said at least one contact, respectively; and biasing means for continuously urging said movable plate toward said no-load insertion position with a force insufficient to disengage the at least one terminal from said at least one contact but sufficient to move said plate into said no-load insertion position when the at least one terminal is not engaged with said at least one contact, respectively.
Claim 3
Dependent Claim
25 words
A socket as recited in claim 1, wherein said biasing means comprises a coil spring operatively interposed between said socket body and said movable plate.
Claim 4
Dependent Claim
28 words
A socket as recited in claim 1, wherein said biasing means comprises a winding comprises a winding spring operatively interposed between said socket body and said movable plate.
Claim 5
Dependent Claim
25 words
A socket as recited in claim 1, wherein said biasing means comprises a plate spring operatively interposed between said socket body and said movable plate.
Claim 6
Dependent Claim
47 words
A socket as recited in claim 1, wherein said at least one terminal insertion hole, said at least one contact, and said at least one no-load insertion space comprise a plurality of terminal insertion holes, a plurality of contacts, and a plurality of no-load insertion spaces, respectively.
Claim 7
Dependent Claim
26 words
A socket as recited in claim 1, wherein said biasing means is further operable to prevent rattling of said movable plate relative to said socket body.
Claim 8
Dependent Claim
29 words
A socket as recited in claim 6, further comprising means for forcing said movable plate to slide into said contacting position against the biasing force of said biasing means.
Claim 9
Dependent Claim
26 words
A socket as recited in claim 7, wherein said forcing means comprises an operation lever operatively connected to both said socket body and said movable plate.
Claim 10
Dependent Claim
29 words
A socket as recited in claim 1, further comprising means for forcing said movable plate to slide into said contacting position against the biasing force of said biasing means.
Claim 11
Dependent Claim
26 words
A socket as recited in claim 1, wherein said forcing means comprises an operation lever operatively connected to both said socket body and said movable plate.
