Abstract
Abstract A circuit board pin socket having an eyelet defined by an elongate hollow conductive metal body with an inside surface suitable for electrical contact with a male pin member. A plug of heat-resistant polymeric material extends through and fills the inside of the eyelet for protection thereof during fluxing and subsequent wave soldering of the socket to a printed circuit board. The socket has at least three angularly disposed spring arms which extend from an end of the eyelet and operate to position the socket in a circuit board hole.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
139 words
A circuit board socket comprising: (a) an eyelet, said eyelet defined by an elongate hollow conductive metal body having a generally cylindrical configuration, the body having open first and second ends, (b) at least three spaced-apart spring arms extending from said first end of the eyelet, each arm having a reverse bend away from said first end forming an acute angle with the eyelet body, each of said arms having a greater physical length than the eyelet so that each arm protrudes above the eyelet when the eyelet is mounted in a circuit board, (c) each spring arm portion forming the acute angle with the eyelet body being straight except for inwardly hooked ends located adjacent the second end of the eyelet when mounted in a circuit board to insure mechanical retention of the socket in the circuit board.
Claim 2
Dependent Claim
139 words
A circuit board socket comprising: (a) an eyelet, said eyelet defined by an elongate hollow conductive metal body having a generally cylindrical configuration, the body having open first and second ends, (b) at least three spaced-apart spring arms extending from said first end of the eyelet, each arm having a reverse bend away from said first end forming an acute angle with the eyelet body, each of said arms having a greater physical length than the eyelet so that each arm protrudes above the eyelet when the eyelet is mounted in a circuit board, (c) each spring arm portion forming the acute angle with the eyelet body being straight except for inwardly hooked ends located adjacent the second end of the eyelet when mounted in a circuit board to insure mechanical retention of the socket in the circuit board.
Claim 3
Dependent Claim
19 words
The socket of claim 1 wherein a removable plug of heat-resistant polymeric material extends through and fills the eyelet.
Claim 4
Dependent Claim
18 words
