Abstract
Abstract A filtered socket decouples the pin of an electronic circuit device such as a transistor or a thin film amplifier. The tubular socket is constructed of a resilient metal with a pin receiving opening at one end and a resilient tail at the other end. A tubular filter is soldered onto the socket. This filter has a metal flange which is positioned against the plated through circuit in a hole on the circuit board. The filtered socket is locked to the board by resiliently positioning the tail in another hole in the circuit board. The board is flow soldered to establish an electrical connection between the outer conductive surface of the filter and a common electronic connection extending to the hole in which the socket is positioned. Another electrical connection is established between the circuit extending to the other hole and the socket itself. A solder-free plastic coating on a portion of the filter and a portion of the tail prevents solder from bridging the two holes.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
145 words
A filtered socket arrangement for decoupling the inserted pins of an electronic circuit device to be mounted on a circuit board comprising: a tubular socket having an opening at one end thereof for receiving one of said pins and having a resilient tail secured at the other end thereof, a tubular filter of the type having an inner conductive surface and an outer conductive surface separated by dielectric material, said tubular socket being secured within said tubular filter in conductive engagement with the inner conductive surface thereof, and a metal flange on said filter so that said filtered socket can be mounted in one hole in said circuit board with the flange against a surface of the board and said tail resiliently bearing against the wall of another hole to retain said filter and socket assembly on said board by the resiliency of the tail.
Claim 2
Dependent Claim
145 words
A filtered socket arrangement for decoupling the inserted pins of an electronic circuit device to be mounted on a circuit board comprising: a tubular socket having an opening at one end thereof for receiving one of said pins and having a resilient tail secured at the other end thereof, a tubular filter of the type having an inner conductive surface and an outer conductive surface separated by dielectric material, said tubular socket being secured within said tubular filter in conductive engagement with the inner conductive surface thereof, and a metal flange on said filter so that said filtered socket can be mounted in one hole in said circuit board with the flange against a surface of the board and said tail resiliently bearing against the wall of another hole to retain said filter and socket assembly on said board by the resiliency of the tail.
Claim 3
Dependent Claim
47 words
The filtered socket recited in claim 1 wherein said tail portion has two bends of at least 90* each so that said socket can be in one hole in said circuit board with said tail extending into another hole in the same plane of said circuit board.
Claim 4
Dependent Claim
26 words
The filtered socket recited in claim 1 wherein said flange is on a metallic eyelet secured to and about the outer conductive surface of said filter.
Claim 5
Dependent Claim
73 words
The filtered socket recited in claim 1 wherein a coating of a solder-free plastic is provided on a portion of the outer conductive surface of said filter and a portion of said tail which extends from said filter so that said socket can be dip soldered to said board without forming a solder bridge between the outer conductive surface of said filter and the end of said tail bearing against said other hole.
Claim 6
Dependent Claim
36 words
The socket recited in claim 1 wherein said filter comprises a ferrite tube coated with barium titanate so that said filtered socket can be dip soldered to said circuit without causing heat damage to said filter.
Claim 7
Independent Claim
115 words
The method of assembling a filtered socket to a circuit board of the type having electronic circuit connections extending between holes which receive circuit devices comprising: soldering the inner conductive surface of a tubular filter having a surrounding flange to the outer surface of a tubular socket mounted therein near the pin receiving end of said socket, said socket having a resilient tail extending therefrom, positioning said filter socket in a hole in a circuit board with said flange bearing against a common electronic circuit connection extending to that hole, and locking said filtered socket on said circuit board by resiliently positioning said tail in another hole having a conductor of the electronic circuit therein.
Claim 8
Independent Claim
115 words
The method of assembling a filtered socket to a circuit board of the type having electronic circuit connections extending between holes which receive circuit devices comprising: soldering the inner conductive surface of a tubular filter having a surrounding flange to the outer surface of a tubular socket mounted therein near the pin receiving end of said socket, said socket having a resilient tail extending therefrom, positioning said filter socket in a hole in a circuit board with said flange bearing against a common electronic circuit connection extending to that hole, and locking said filtered socket on said circuit board by resiliently positioning said tail in another hole having a conductor of the electronic circuit therein.
