Abstract

Abstract An improved insulation piercing contact for use in an electrical connector is provided. The contact is made of a sheet metal stamping, which includes a top portion for making electrical contact with a first conductor, and a bottom portion which includes at least two tines. Each tine is bevelled and has a bottom edge which pierces the insulation of a second conductor and makes contact. The tines may project away from one of the planar surfaces of the contact.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 172 words
An electrical connector comprising: a thin sheet metal stamping, said stamping including a body portion having a substantially flat top surface adapted to make electrical contact with a first conductor; said stamping further including at least a first and a second tine connected to said body portion, said tines being adjacent to one another, each tine having a pair of side surfaces, at least a portion of the opposite side surfaces of adjacent tines are bevelled forming bottom edges adapted to score opposite sides of an elongated second conductor so that the side surfaces which are bevelled are adapted to make contact with and terminate to the elongated second conductor, said tines being thinner at said bottom edges than where said tines are connected to said body portion, said tines being in substantially the same plane as said body portion when said tines are not in contact with the elongated second conductor with said bottom edges of adjacent tines being on opposite sides of the widest central sectional plane of said stamping.
Claim 2
Dependent Claim 172 words
An electrical connector comprising: a thin sheet metal stamping, said stamping including a body portion having a substantially flat top surface adapted to make electrical contact with a first conductor; said stamping further including at least a first and a second tine connected to said body portion, said tines being adjacent to one another, each tine having a pair of side surfaces, at least a portion of the opposite side surfaces of adjacent tines are bevelled forming bottom edges adapted to score opposite sides of an elongated second conductor so that the side surfaces which are bevelled are adapted to make contact with and terminate to the elongated second conductor, said tines being thinner at said bottom edges than where said tines are connected to said body portion, said tines being in substantially the same plane as said body portion when said tines are not in contact with the elongated second conductor with said bottom edges of adjacent tines being on opposite sides of the widest central sectional plane of said stamping.
Claim 3
Dependent Claim 35 words
An electrical contact as set forth in claim 1, further including a pair of barbs projecting from the sides of said body portion of said stamping for retaining said stamping in an electrical connector body.
Claim 4
Dependent Claim 38 words
An electrical connector as set forth in claim 1, further including a third tine connected to said body portion adjacent to said second tine, said third tine being bevelled on the same side surface as said first tine.
Claim 5
Dependent Claim 23 words
An electrical connector as set forth in claim 1, wherein said bottom edges of said tines are curved to aid in cutting ability.
Claim 6
Dependent Claim 230 words
An electrical assembly comprising: a housing having a front portion and a rear portion; an electrical cable; a first opening located in the rear portion of said housing receiving said electrical cable, said cable having at least one elongated conductor; at least one electrical contact; a second opening in the top of the front portion of said housing, said second opening receiving said electrical contact; said contact formed as a thin sheet metal stamping, said stamping including a body portion having a substantially flat top surface, said stamping further including at least a first and a second tine adjacent to one another, each tine being connected to said body portion, each tine having a pair of side surfaces, at least a portion of the opposite side surfaces of adjacent tines are bevelled forming bottom edges adapted to score opposite sides of said elongated conductor, the side surfaces of said tines which are bevelled making contact with and being terminated to said elongated conductor, said tines being thinner at said bottom edges than where said tines are connected to said body portion, said bottom edges of said adjacent tines substantially flairing out in opposing directions away from the plane of said body portion and penetrating into said housing so that the distance between the bottom edges of said first and second tines is substantially greater than the thickness of said stamping.
Claim 7
Dependent Claim 230 words
An electrical assembly comprising: a housing having a front portion and a rear portion; an electrical cable; a first opening located in the rear portion of said housing receiving said electrical cable, said cable having at least one elongated conductor; at least one electrical contact; a second opening in the top of the front portion of said housing, said second opening receiving said electrical contact; said contact formed as a thin sheet metal stamping, said stamping including a body portion having a substantially flat top surface, said stamping further including at least a first and a second tine adjacent to one another, each tine being connected to said body portion, each tine having a pair of side surfaces, at least a portion of the opposite side surfaces of adjacent tines are bevelled forming bottom edges adapted to score opposite sides of said elongated conductor, the side surfaces of said tines which are bevelled making contact with and being terminated to said elongated conductor, said tines being thinner at said bottom edges than where said tines are connected to said body portion, said bottom edges of said adjacent tines substantially flairing out in opposing directions away from the plane of said body portion and penetrating into said housing so that the distance between the bottom edges of said first and second tines is substantially greater than the thickness of said stamping.
Claim 8
Dependent Claim 17 words
An electrical assembly as set forth in claim 5, wherein said cable is substantially a flat cable.
Claim 9
Dependent Claim 30 words
An electrical assembly as set forth in claim 5, further including a pair of barbs projecting away from the side of said contact for retaining said contact in said housing.
Claim 10
Dependent Claim 54 words
An electrical assembly as set forth in claim 5, further including a third tine adjacent to said second tine and being bevelled in substantially a similar manner to said first tine, said third tine flairing out from the plane of said body portion in the same direction and same manner as said first tine.
Claim 11
Dependent Claim 18 words
An electrical assembly as set forth in claim 5, wherein said bottom edges of said tines are curved.
