Abstract
Abstract A connector and terminal for insulated wire which includes a pin section particularly adapted to extend through an aperture in a circuit board. The connector, which is formed of a single piece of electrically conductive metal includes a tubular section adapted to receive and make electrical contact with an insulated wire, and an isolation section which is positioned between the tubular section and the pin section. The isolation section permits the pin section to be wave soldered on the other side of the circuit board without being contaminated by the insulated wire, and also protects the insulated wire from damage during soldering. The isolation section may take one of several forms, and may include a heat sink for further dissipating the heat resulting from the soldering process. Insulation displacement tynes are provided in the tubular section for making positive electrical contact with the wire. The pin section itself may be either press fit through the circuit board aperture, or may include one of several different locking features.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
127 words
An electrical connector, which comprises an electrically conductive piece of sheet metal which is integrally formed to provide: tubular means adapted to receive an insulated wire therewithin; pin means adapted to extend through an aperture in a circuit board; and isolation means extending between said tubular means and said pin means for spacing said tubular means from the top surface of said board; wherein said tubular means includes means integrally formed therefrom adapted to pierce the insulation of said insulated wire and to establish electrical contact with said wire; and wherein said tubular means comprises a cylindrical barrel, said insulated wire adapted to extend to the bottom end of said barrel, and said isolation means further comprises means for substantially covering said bottom end of said barrel.
Claim 2
Dependent Claim
127 words
An electrical connector, which comprises an electrically conductive piece of sheet metal which is integrally formed to provide: tubular means adapted to receive an insulated wire therewithin; pin means adapted to extend through an aperture in a circuit board; and isolation means extending between said tubular means and said pin means for spacing said tubular means from the top surface of said board; wherein said tubular means includes means integrally formed therefrom adapted to pierce the insulation of said insulated wire and to establish electrical contact with said wire; and wherein said tubular means comprises a cylindrical barrel, said insulated wire adapted to extend to the bottom end of said barrel, and said isolation means further comprises means for substantially covering said bottom end of said barrel.
Claim 3
Dependent Claim
33 words
An electrical connector as set forth in claim 1, wherein said insulation piercing means comprises at least one substantially triangularly shaped tyne stamped from said tubular means so as to extend inwardly thereof.
Claim 4
Dependent Claim
29 words
An electrical connector as set forth in claim 2, further comprising a second tyne positioned below and spaced laterally on said tubular means from said at least one tyne.
Claim 5
Dependent Claim
25 words
An electrical connector as set forth in claim 1, wherein said isolation means includes means for dissipating the heat from said piece of sheet metal.
Claim 6
Dependent Claim
38 words
An electrical connector as set forth in claim 1, wherein said covering means comprises a piece of metal extending integrally from one side of said barrel underneath said bottom end thereof to the other side of said barrel.
Claim 7
Dependent Claim
46 words
An electrical connector as set forth in claim 5, wherein said isolation means further comprises a shoulder extending integrally from said piece of metal at said other side of said barrel to said pin means for seating said connector on the top surface of said board.
Claim 8
Dependent Claim
66 words
An electrical connector as set forth in claims 1 or 6, wherein said pin means comprises a first leg extending integrally and vertically downwardly from said isolation means and a second vertical leg extending integrally and upwardly adjacent to and from said first vertical leg, said first and second legs forming resilient spring means having a width greater than that of said aperture in said board.
Claim 9
Dependent Claim
31 words
An electrical connector as set forth in claim 7, wherein said second leg terminates in offset tip means extending towards said first leg for locking said pin means in said aperture.
Claim 10
Dependent Claim
33 words
An electrical connector as set forth in claim 1, wherein said covering means comprises a substantially conically shaped metallic portion extending integrally from said bottom end of said barrel to said pin means.
Claim 11
Dependent Claim
38 words
An electrical connector as set forth in claims 1 or 9, wherein said pin means comprises a tubular portion extending integrally from said isolation means and adapted to be press fit within said aperture in said circuit board.
Claim 12
Dependent Claim
22 words
An electrical connector as set forth in claim 1, wherein said tubular means is formed from crimping a substantially U-shaped channel member.
