Abstract
Abstract A component and method are provided for making a soldered electrical connection between two mating members, in which a deposit of solder on the surface of one of the members is juxtaposed to a cooperatively shaped surface on the other member when the two members are mated, so that the solder will melt and bind the two surfaces when heated. The quality of this connection may be further improved by providing a resilient arrangement for urging the conforming surfaces together as heat is applied. In one form of contact element according to the invention a hollow, cylindrical metal shell with a longitudinal split provides a resilient fit into a mating member, such as a metal-lined hole on a printed circuit board. The shell is provided with a deposit of solder in a groove on its outer surface where the shell is to engage the metal lining of the hole.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
138 words
A contact element adapted to form one member of an electrical connection arrangement having mating male and female members, comprising: a body having an engaging surface conforming substantially to a corresponding surface on the mating member; said body having a peripheral groove communicating with said engaging surface; a deposit of solder in said groove, said solder including a peripheral ridge portion projecting away from the groove and extending beyond said engaging surface, said ridge portion being adapted to be at least partially displaced from the remaining solder in said groove upon mating of said members; whereby, upon mating of said members, at least a portion of said ridge of solder is externally visible at the juncture of said mated members; said contact member further including at least one longitudinal channel communicating with and substantially perpendicular to said groove.
Claim 2
Dependent Claim
138 words
A contact element adapted to form one member of an electrical connection arrangement having mating male and female members, comprising: a body having an engaging surface conforming substantially to a corresponding surface on the mating member; said body having a peripheral groove communicating with said engaging surface; a deposit of solder in said groove, said solder including a peripheral ridge portion projecting away from the groove and extending beyond said engaging surface, said ridge portion being adapted to be at least partially displaced from the remaining solder in said groove upon mating of said members; whereby, upon mating of said members, at least a portion of said ridge of solder is externally visible at the juncture of said mated members; said contact member further including at least one longitudinal channel communicating with and substantially perpendicular to said groove.
Claim 3
Dependent Claim
162 words
A solderable connector arrangement for establishing an electrical connection, comprising: a male member having a body with an outer surface and a female member having a body with an inner surface, said outer and inner surface conforming substantially to each other when said male and female members are mated; at least one of said members having a peripheral groove communicating with its respective surface; a deposit of solder in said groove, said solder including a peripheral ridge portion projecting away from the groove and extending beyond the respective surface, said ridge portion being adapted to be at least partially displaced from the solder in the said groove upon mating of said members; whereby, upon mating of said members, at least a portion of said ridge of solder is externally visible at the juncture of said mated members; at least one of said members further including at least one longitudinal channel disposed to be in communication with and substantially perpendicular to said groove.
Claim 4
Dependent Claim
162 words
A solderable connector arrangement for establishing an electrical connection, comprising: a male member having a body with an outer surface and a female member having a body with an inner surface, said outer and inner surface conforming substantially to each other when said male and female members are mated; at least one of said members having a peripheral groove communicating with its respective surface; a deposit of solder in said groove, said solder including a peripheral ridge portion projecting away from the groove and extending beyond the respective surface, said ridge portion being adapted to be at least partially displaced from the solder in the said groove upon mating of said members; whereby, upon mating of said members, at least a portion of said ridge of solder is externally visible at the juncture of said mated members; at least one of said members further including at least one longitudinal channel disposed to be in communication with and substantially perpendicular to said groove.
