Abstract
Abstract A top housing, which has formed therein arrays of first housing chambers and first pin insertion holes respectively communicating therewith, and a bottom housing, which has formed therein arrays of second housing chambers and second pin insertion holes respectively communicating therewith, are assembled together so that the corresponding first and second housing chambers intercommunicate. A socket contactor is housed across the corresponding first and second housing chambers. The top and bottom housings are held together by a frame so that they are slidable relative to each other. Terminal pins of an IC are inserted into the first housing chambers through the first pin insertion holes and pin conductors of a printed board are inserted into the second housing chambers through the second pin insertion holes. By sliding the top and bottom housings relative to each other, each socket contactor is bent, and by its spring force, the socket contactor is urged against the terminal pin and the pin conductor.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
200 words
A connector comprising: a top housing having arrays of first pin insertion holes made in its upper panel and arrays of first housing chambers formed therein, each first housing chamber extending from the corresponding first pin insertion hole to the lower panel of the top housing and having a first wall surface with which a terminal pin inserted thereinto through the corresponding first pin insertion hole makes contact in its lengthwise direction and a second wall surface opposite the first wall surface; a bottom housing disposed with its upper panel held in contact with the lower panel of the top housing and slidable relative thereto, the bottom housing having arrays of second pin insertion holes made in its lower panel and arrays of second housing chambers formed therein, each second housing chamber extending from the corresponding second pin insertion hole to the upper panel of the bottom housing; narrow, strip-shaped resilient metal socket contactors, each extending across and housed in each pair of first and second housing chambers; means for holding the top and bottom housings together so that they are slidable relative to each other; and drive means for sliding the top and bottom housings relative to each other.
Claim 2
Dependent Claim
200 words
A connector comprising: a top housing having arrays of first pin insertion holes made in its upper panel and arrays of first housing chambers formed therein, each first housing chamber extending from the corresponding first pin insertion hole to the lower panel of the top housing and having a first wall surface with which a terminal pin inserted thereinto through the corresponding first pin insertion hole makes contact in its lengthwise direction and a second wall surface opposite the first wall surface; a bottom housing disposed with its upper panel held in contact with the lower panel of the top housing and slidable relative thereto, the bottom housing having arrays of second pin insertion holes made in its lower panel and arrays of second housing chambers formed therein, each second housing chamber extending from the corresponding second pin insertion hole to the upper panel of the bottom housing; narrow, strip-shaped resilient metal socket contactors, each extending across and housed in each pair of first and second housing chambers; means for holding the top and bottom housings together so that they are slidable relative to each other; and drive means for sliding the top and bottom housings relative to each other.
Claim 3
Dependent Claim
54 words
The connector of claim 1, wherein one end portion of each socket contactor housed in the corresponding first housing chamber is substantially S-shaped and includes a first curved portion adjacent the first wall surface of the first housing chamber and a second curved portion adjacent the second wall surface of the first housing chamber.
Claim 4
Dependent Claim
32 words
The connector of claim 2, wherein engaging means for supporting the other end portion of each socket contactor is provided near the second pin insertion hole of the corresponding second housing chamber.
Claim 5
Dependent Claim
67 words
The connector of claim 1, 2 or 3, wherein each second pin insertion hole is longer than the distance of the relative sliding movement of the top and bottom housings in the direction of the sliding movement and permits a pin conductor inserted into the second pin insertion hole to slide relative to the bottom housing when the top and bottom housing slide relative to each other.
Claim 6
Dependent Claim
44 words
The connector of claim 1, wherein each second housing chamber has a first wall surface with which a pin conductor inserted thereinto through the corresponding pin insertion hole make contact in its lengthwise direction and a second wall surface opposite the first wall surface.
Claim 7
Dependent Claim
109 words
The connector of claim 5, wherein one end portion of each socket contactor housed in the corresponding first housing chamber is substantially S-shaped portion and includes a first curved portion adjacent the first wall surface of the first housing chamber and a second curved portion making contact with the second wall surface of the first housing chamber, and the other end portion of the socket contactor housed in the corresponding second housing chamber is substantially S-shaped and includes a third curved portion adjacent the first wall surface of the second housing chamber and a fourth curved portion making contact with the second wall surface of the second housing chamber.
Claim 8
Dependent Claim
34 words
The connector of claim 1, wherein each first pin insertion hole is formed so that part of its inner peripheral wall is contiguous to the first wall surface of the corresponding first housing chamber.
Claim 9
Dependent Claim
35 words
The connector of claim 8, wherein each second pin insertion hole is formed so that a part of its inner peripheral wall is contiguous to the first wall surface of the corresponding second housing chamber.
Claim 10
Dependent Claim
48 words
The connector of claim 5, wherein each socket contactor is flat and the second wall surface of each first housing chamber has a first edge for contact with a first intermediate portion of the socket contactor when the top and bottom housings are slid relative to each other.
Claim 11
Dependent Claim
42 words
The connector of claim 9, wherein the second wall surface of each second housing chamber has a second edge for contact with a second intermediate portion of the socket contactor when the top and bottom housings are slid relative to each other.
Claim 12
Dependent Claim
170 words
A connector comprising: a housing having arrays of first pin insertion holes made in its upper panel and arrays of housing chambers formed therein, each housing chamber extending from the corresponding first pin insertion hole to the lower panel of the housing and having a first wall surface with which a terminal pin inserted thereinto through the corresponding first pin insertion hole makes contact in its lengthwise direction and a second wall surface opposite the first wall surface; a cover plate held in contact with the lower panel of the housing but slidable relative thereto and having arrays of second pin insertion holes, the cover plate having an engaging recess adjacent each second pin insertion hole; narrow, strip-shaped metal socket contactors respectively housed in the housing chambers and engaged at one end with the engaging recess; means for holding the housing and the cover plate together so that they are slidable relative to each other; and drive means for sliding the housing and the cover plate relative to each other.
