Abstract
Abstract An electrical connector for forming an electrical solder connection comprises an electrically insulating open-ended sleeve 2 which is preferably heat-shrinkable, a pre-installed conductor 5 e.g. for forming an earth connection or for forming a connection to a pcb, and a quantity of solder 3 for forming an electrical connection between the pre-installed conductor and another conductor that is received in the sleeve. The pre-installed conductor has a region of non-uniform cross-section, for example produced by crimping, that will be contacted by the solder when the connection is formed and which increases the force required to pull the two conductors apart.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
97 words
An electrical connector for forming an electrical solder connection, which comprises an electrically insulating open-ended sleeve that is capable of receiving an electrical conductor, the sleeve having a pre-installed elongate electrical conductor that extends beyond the sleeve and a quantity of solder for forming an electrical connection between the conductors, wherein the pre-installed conductor has a region which will be contacted by the solder when the connection is formed and which has a cross-section that changes along its length so as to increase the force required to pull the two conductors apart in the completed solder connection.
Claim 2
Dependent Claim
97 words
An electrical connector for forming an electrical solder connection, which comprises an electrically insulating open-ended sleeve that is capable of receiving an electrical conductor, the sleeve having a pre-installed elongate electrical conductor that extends beyond the sleeve and a quantity of solder for forming an electrical connection between the conductors, wherein the pre-installed conductor has a region which will be contacted by the solder when the connection is formed and which has a cross-section that changes along its length so as to increase the force required to pull the two conductors apart in the completed solder connection.
Claim 3
Dependent Claim
23 words
A connector as claimed in claim 1, wherein the pre-installed conductor has been crimped in order to vary its cross-section along its length.
Claim 4
Dependent Claim
24 words
A connector as claimed in claim 2, wherein the conductor has areas that have been flattened and alternating areas that have not been flattened.
Claim 5
Dependent Claim
13 words
A connector as claimed in claim 1, wherein the sleeve is dimensionally heat-recoverable.
