Abstract
Abstract An improved electrical contact is shown, having a box-like section capable of mating with a square post or round pin at one end and an open barrel section for crimping upon an insulated, stripped wire at the other end. The box-like section and open barrel section are joined by a central box section which includes a retention leaf spring and an internal stop for controlling the seating of the contact upon the square post or round pin, for providing a stop for the wire, and for strengthening the box sections as the contact is crimped upon the wire.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
163 words
An electrical contact for joining electrically conductive elements, comprising: a first conductive element; a box-like end section for receiving said first conductive element formed from a metal sheet having four side walls; a second conductive element; an open barrel crimp section for receiving said second conductive element; a central box section formed by the extension of said four walls of said box-like end section; one of said four walls further extended for joining said central box section and said open barrel crimp section; support means formed by the further extension of two of said four walls perpendicular to said four walls having contiguous facing surfaces for strengthening said contact; and said support means formed by said two perpendicular walls having inner surfaces abutting said first conductive element and outer surfaces abutting said second conductive element to form a stop for said first and second conductive elements whose contiguous surfaces and abutting contact with said first and second conductive elements further strengthens said contact.
Claim 2
Dependent Claim
163 words
An electrical contact for joining electrically conductive elements, comprising: a first conductive element; a box-like end section for receiving said first conductive element formed from a metal sheet having four side walls; a second conductive element; an open barrel crimp section for receiving said second conductive element; a central box section formed by the extension of said four walls of said box-like end section; one of said four walls further extended for joining said central box section and said open barrel crimp section; support means formed by the further extension of two of said four walls perpendicular to said four walls having contiguous facing surfaces for strengthening said contact; and said support means formed by said two perpendicular walls having inner surfaces abutting said first conductive element and outer surfaces abutting said second conductive element to form a stop for said first and second conductive elements whose contiguous surfaces and abutting contact with said first and second conductive elements further strengthens said contact.
Claim 3
Dependent Claim
17 words
An electrical contact as claimed in claim 1 wherein said first conductive element is a square post.
Claim 4
Dependent Claim
17 words
An electrical contact as claimed in claim 1 wherein said first conductive element is a round pin.
Claim 5
Dependent Claim
17 words
An electrical contact as claimed in claim 1 wherein said second conductive element is an insulated wire.
Claim 6
Dependent Claim
22 words
An electrical contact as claimed in claim 1 wherein said four side walls are equal in width and said contact is square.
Claim 7
Dependent Claim
147 words
An electrical contact for joining electrically conductive elements, comprising: a conductive pin; a box-like end section for receiving said pin formed from four equal side walls; a conductive wire; an open barrel crimp section for receiving said wire; one of said four walls extended from said box-like end section to join said open barrel crimp section thereto; two more of said four walls extending perpendicularly into said box-like end section at the jointure of said open barrel crimp section having contiguous facing edges to form a contact support for strengthening said contact; and said contact support formed by said two perpendicularly extending walls having inner and outer surfaces, said inner surfaces abutting said pin and said outer surfaces abutting said wire to form a contact stop whose contiguous edges and abutting contact with said pin and wire further strengthen said contact while stopping said pin and wire.
Claim 8
Dependent Claim
147 words
An electrical contact for joining electrically conductive elements, comprising: a conductive pin; a box-like end section for receiving said pin formed from four equal side walls; a conductive wire; an open barrel crimp section for receiving said wire; one of said four walls extended from said box-like end section to join said open barrel crimp section thereto; two more of said four walls extending perpendicularly into said box-like end section at the jointure of said open barrel crimp section having contiguous facing edges to form a contact support for strengthening said contact; and said contact support formed by said two perpendicularly extending walls having inner and outer surfaces, said inner surfaces abutting said pin and said outer surfaces abutting said wire to form a contact stop whose contiguous edges and abutting contact with said pin and wire further strengthen said contact while stopping said pin and wire.
