Abstract
Abstract An electrical connector-terminal device is disclosed which features a conductor lead receiving barrel lined with solder and containing spring means adapted to be loaded by lead insertion to force the lead into engagement with the solder prior to and during solder reflow as effected by heat applied to the device. The barrel includes a stop and projections which operate in conjunction with the spring means to mechanically stabilize the lead during solder reflow. A heat shrinkable sleeve is applied over the region of joint between the lead and the device to prevent solder escape and to seal the joint relative to the insulating sheath of the lead terminated thereby.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
205 words
A device for connecting and/or terminating electrical lead wires including a body formed of metal to define a forward connection portion and a wire receiving barrel portion, the said barrel portion including on an interior surface thereof a layer of solder, at least one spring element extending into said barrel portion, the interior cross-sectional diameter of said barrel portion between the interior surface of said spring element and the opposing wall surfaces of said barrel portion being appreciably less than the outer diameter of a lead wire to be inserted therein, whereby to engage and firmly grip the conductive strands of a lead wire inserted within said barrel portion and to maintain a force better assuring the conduction of heat to effect solder reflow, thereby joining the lead wire to the device, said barrel portion further including stop means extended over the end thereof opposite to the end of insertion of the lead wire, said stop means serving to accurately position the lead wire relative to the interior of the barrel portion and the surface of the spring element, and said barrel portion including means positioned to grip the insulating sheath of said lead wire and hold said lead wire in against said stop means.
Claim 2
Independent Claim
205 words
A device for connecting and/or terminating electrical lead wires including a body formed of metal to define a forward connection portion and a wire receiving barrel portion, the said barrel portion including on an interior surface thereof a layer of solder, at least one spring element extending into said barrel portion, the interior cross-sectional diameter of said barrel portion between the interior surface of said spring element and the opposing wall surfaces of said barrel portion being appreciably less than the outer diameter of a lead wire to be inserted therein, whereby to engage and firmly grip the conductive strands of a lead wire inserted within said barrel portion and to maintain a force better assuring the conduction of heat to effect solder reflow, thereby joining the lead wire to the device, said barrel portion further including stop means extended over the end thereof opposite to the end of insertion of the lead wire, said stop means serving to accurately position the lead wire relative to the interior of the barrel portion and the surface of the spring element, and said barrel portion including means positioned to grip the insulating sheath of said lead wire and hold said lead wire in against said stop means.
Claim 3
Dependent Claim
53 words
The device of claim 1 wherein there is provided a sleeve of heat shrinkable insulating material fitted over said barrel portion with one end thereof extending outboard of said barrel portion so as to engage thE insulating sheath of a lead wire and effect partial seal of the interior of said wire barrel.
Claim 4
Dependent Claim
49 words
The device of claim 2 wherein said sleeve is made to extend over the entire exterior surface of said wire barrel and to overlie the said spring element whereby to prevent solder displaced by the force generated from said spring element during reflow from escaping from said wire barrel.
Claim 5
Dependent Claim
179 words
In a device for terminating electrical lead wires a connector-terminal formed of flat sheet stock metal having a lamination of solder extending over portions thereof, said connector terminal being blanked and formed to define a contact portion and a wire barrel portion comprised of the stock and the lamination of solder, said connector-terminal including in said wire barrel portion at least one spring element struck up from the stock to extend into the wire barrel portion, such spring element containing on the interior surface thereof a portion of the solder lamination, said spring element being displaced interiorly of said wire barrel portion so as to be loaded by the insertion of the lead wire into said barrel portion to firmly grip the surface of said lead wire and press such between the surfaces of said solder on the interior of said barrel portion and on said spring element whereby to better assure conduction of heat to effect solder reflow and to force reflowed solder into the interstices of the strands of the lead wire to provide a termination thereof.
Claim 6
Dependent Claim
179 words
In a device for terminating electrical lead wires a connector-terminal formed of flat sheet stock metal having a lamination of solder extending over portions thereof, said connector terminal being blanked and formed to define a contact portion and a wire barrel portion comprised of the stock and the lamination of solder, said connector-terminal including in said wire barrel portion at least one spring element struck up from the stock to extend into the wire barrel portion, such spring element containing on the interior surface thereof a portion of the solder lamination, said spring element being displaced interiorly of said wire barrel portion so as to be loaded by the insertion of the lead wire into said barrel portion to firmly grip the surface of said lead wire and press such between the surfaces of said solder on the interior of said barrel portion and on said spring element whereby to better assure conduction of heat to effect solder reflow and to force reflowed solder into the interstices of the strands of the lead wire to provide a termination thereof.
Claim 7
Dependent Claim
174 words
For use in terminating electrical lead wires of a type having a core of conductive material and a sheath of insulating material thereon, a series of terminal bodies each formed from a common piece of thin sheet metal having a layer of solder laminated thereto with each said body including a wire receiving barrel portion formed to have an area of said solder layer disposed on the inner surface thereof and with said bodies joined together by a web of said sheet metal as a carrier for said bodies, and with each of said wire barrel portions further having in combination, a stop means for limiting lead wire insertion to align the stripped surface of said care with said layer of solder, means included in said wire barrel portion for gripping the insulating sheath of said lead wire to hold said core in place in said barrel portion, and spring means included in said barrel portion for pressing said core against said layer of solder during solder reflow to terminate a lead wire thereto.
