Abstract
Abstract A cylindrical circuit board socket with a metal body open at each end having a pair of lead contact fingers extending from one end into the interior of the socket for forming an electrical connection with a lead inserted into the socket and a pair of circuit board contact fingers extending from the other end along the outside of the body for holding the socket in a circuit board hole prior to soldering the socket to printed circuitry at the hole. A seal at each end of the body closes the interior of the body and prevents flux and solder from flowing into the interior of the socket during fluxing and soldering of the socket. A contact lead is easily inserted into the socket through a seal to form an electrical connection with the interior fingers.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
163 words
A circuit board socket comprising an elongate hollow metal body open at each end thereof; a pair of diametrally opposed circuit board contact fingers each extending from one end of the body inwardly toward the axis of the body around a reverse bend of greater than 180* and then along the outer surface of the body, said contact fingers being outwardly bowed of said surface for retaining the circuit board socket in a circuit board hole; a pair of diametrally opposed lead contact fingers each extending from the other end of the body outwardly of the body around a reverse bend of greater than 180* through the opening at said other end of the body and into the interior of the body, such contact fingers being inwardly bowed toward each other within the body to define contact areas closely spaced for forming an electrical connection with a lead inserted into the body through an end of the body and between such spring fingers.
Claim 2
Dependent Claim
163 words
A circuit board socket comprising an elongate hollow metal body open at each end thereof; a pair of diametrally opposed circuit board contact fingers each extending from one end of the body inwardly toward the axis of the body around a reverse bend of greater than 180* and then along the outer surface of the body, said contact fingers being outwardly bowed of said surface for retaining the circuit board socket in a circuit board hole; a pair of diametrally opposed lead contact fingers each extending from the other end of the body outwardly of the body around a reverse bend of greater than 180* through the opening at said other end of the body and into the interior of the body, such contact fingers being inwardly bowed toward each other within the body to define contact areas closely spaced for forming an electrical connection with a lead inserted into the body through an end of the body and between such spring fingers.
Claim 3
Dependent Claim
27 words
A circuit board socket as in claim 1, including sealing means for closing the openings at each end of the body, such means extending around said fingers.
Claim 4
Dependent Claim
23 words
A circuit board socket as in claim 2 wherein said sealing means comprises a silicone rubber seal at each end of the body.
Claim 5
Dependent Claim
122 words
A circuit board socket comprising an elongate hollow metal body; a pair of lead contact fingers each extending from one end of said body outwardly of the body around a reverse bend and into the interior of the body, such fingers including closely spaced contact surfaces for forming an electrical connection with a lead inserted into the body and between the fingers; a pair of circuit board contact fingers each extending from one end of said body inwardly toward the axis of the body around a reverse bend and along the outer surface of the body, the portion of such fingers extending along the outer surface of the body outwardly bowed for retaining the circuit board socket in a circuit board hole.
Claim 6
Dependent Claim
122 words
A circuit board socket comprising an elongate hollow metal body; a pair of lead contact fingers each extending from one end of said body outwardly of the body around a reverse bend and into the interior of the body, such fingers including closely spaced contact surfaces for forming an electrical connection with a lead inserted into the body and between the fingers; a pair of circuit board contact fingers each extending from one end of said body inwardly toward the axis of the body around a reverse bend and along the outer surface of the body, the portion of such fingers extending along the outer surface of the body outwardly bowed for retaining the circuit board socket in a circuit board hole.
Claim 7
Dependent Claim
21 words
A circuit board socket as in claim 4, including resilient Sealing means for closing at least one end of said body.
Claim 8
Dependent Claim
104 words
A circuit board socket comprising an elongate hollow open ended metal body; a first pair of opposed spring fingers extending from one end of the body along the outer surface of the body; each spring finger including a portion outwardly bowed of said surface for retaining the socket in a circuit board hole; a second pair of opposed spring fingers extending from the other end of the body; such fingers being inwardly bowed toward each other within the body to define closely spaced contacts for forming an electrical connection with a lead inserted through an end of the body and between said second fingers.
Claim 9
Dependent Claim
104 words
A circuit board socket comprising an elongate hollow open ended metal body; a first pair of opposed spring fingers extending from one end of the body along the outer surface of the body; each spring finger including a portion outwardly bowed of said surface for retaining the socket in a circuit board hole; a second pair of opposed spring fingers extending from the other end of the body; such fingers being inwardly bowed toward each other within the body to define closely spaced contacts for forming an electrical connection with a lead inserted through an end of the body and between said second fingers.
Claim 10
Dependent Claim
88 words
A circuit board socket comprising an elongate generally cylindrical hollow metal body open at both ends; at least a pair of lead contact fingers extending into the body from one end thereof for forming an electrical connection with the lead inserted into the interior of the body through one end of the body; means for mounting the body in a circuit board hole; and penetrable sealing means completely closing each end of the body to prevent flux or molten solder from flowing into the interior of the body.
Claim 11
Dependent Claim
88 words
A circuit board socket comprising an elongate generally cylindrical hollow metal body open at both ends; at least a pair of lead contact fingers extending into the body from one end thereof for forming an electrical connection with the lead inserted into the interior of the body through one end of the body; means for mounting the body in a circuit board hole; and penetrable sealing means completely closing each end of the body to prevent flux or molten solder from flowing into the interior of the body.
Claim 12
Dependent Claim
23 words
A circuit board socket as in claim 7 wherein said means surrounds portions of said fingers at said one end of the body.
