Electrical connector for electrical circuit test probe and connector

Claim 2

An electrical connector comprising: (a) a cylindrical collet member of an electrically conductive material and having jaws at one end facing into a central bore, said member being adapted to have an electrical conductor disposed within said bore and between facing surfaces of said jaws; and (b) a plug housing of an electrically conductive material and adapted for electrical connection to a circuit, said plug housing having a first cylindrical portion having an opening on one end for receiving said collet member and being of an internal diameter to provide a slide fit for said jaws, said first cylindrical portion being connected to a second cylindrical portion by a smoothly tapered portion, said second cylindrical portion having an internal diameter sized such that as said collet member with an electrical conductor disposed therein is slid into said second cylindrical portion through said tapered portion, said jaws are squeezed together with a pressure to cause said jaws to bite into said conductor, the material of said collet member adjacent said jaws subsequently being plastically deformed to facilitate further sliding of said collet member into said plug housing to maintain the jaws in electrical connection with the conductor.

Claim 3

An electrical connector according to claim 1 wherein said facing surfaces of said jaws are connected to the remainder of said member by neck means dimensioned to deform plastically when said jaws have been squeezed into biting contact with said conductor by said tapered portion.

Claim 4

The connector of claim 1, wherein: the end of said plug housing opposite said opening is a closed end extending past said second cylindrical portion and is adapted to be crimp connected into the end of the socket tube of an electrical circuit test probe assembly.

Claim 5

The connector of claim 1, wherein: an insulating collar having an outer diameter greater than that of the remainder of the connector is fitted about said plug housing adjacent said opening.

Claim 6

In an electrical circuit test probe assembly having a socket tube with an electrical test probe on one end, the improvement for providing on the other end a releasable electrical connection to an electrical conductor, comprising: (a) a cylindrical collet member of an electrically conductive material and having jaws at one end facing into a central bore, said member being adapted to have an electrical conductor disposed within said bore and between facing surfaces of said jaws; and, (b) the other end of the test probe terminating in a first cylindrical portion with an opening for receiving said collet member and being of an internal diameter to provide a slide fit for said jaws, said first cylindrical portion being connected to a second cylindrical portion by a smoothly tapered portion, said second cylindrical portion having an internal diameter sized such that as said collet member with an electrical conductor disposed therein is slid into said second cylindrical portion through said tapered portion, said jaws are squeezed together with a pressure to cause said jaws to bite into said conductor, the material of said collet member adjacent said jaws subsequently being plastically deformed to facilitate further sliding of said collet member into said plug housing to maintain the jaws in electrical connection with the conductor.

Claim 7

In an electrical circuit test probe assembly having a socket tube with an electrical test probe on one end, the improvement for providing on the other end a releasable electrical connection to an electrical conductor, comprising: (a) a cylindrical collet member of an electrically conductive material and having jaws at one end facing into a central bore, said member being adapted to have an electrical conductor disposed within said bore and between facing surfaces of said jaws; and, (b) the other end of the test probe terminating in a first cylindrical portion with an opening for receiving said collet member and being of an internal diameter to provide a slide fit for said jaws, said first cylindrical portion being connected to a second cylindrical portion by a smoothly tapered portion, said second cylindrical portion having an internal diameter sized such that as said collet member with an electrical conductor disposed therein is slid into said second cylindrical portion through said tapered portion, said jaws are squeezed together with a pressure to cause said jaws to bite into said conductor, the material of said collet member adjacent said jaws subsequently being plastically deformed to facilitate further sliding of said collet member into said plug housing to maintain the jaws in electrical connection with the conductor.

Claim 8

The improvement of claim 5, wherein said facing surfaces of said jaws are connected to the remainder of said member by neck means dimensioned to deform plastically when said jaws have been squeezed into biting contact with said conductor by said tapered portion.

Claim 9

The improvement of claim 5, wherein: said first and second cylindrical portions are part of a separate electrical connector member and the end of said plug housing opposite said opening is a closed end extending past said second cylindrical portion and is crimp connected into the end of the socket tube.

Claim 10

The improvement of claim 5, wherein: an insulating collar having an outer diameter greater than that of the remainder of the connector is fitted about said plug housing adjacent said opening.

Claim 11

An electrical connector comprising: (a) a cylindrical collet member of an electrically conductive material and having jaws at one end facing into a central bore, said member being adapted to have an electrical conductor disposed within said bore between facing surfaces of said jaws; and (b) a plug housing of an electrically conductive material defining a collet member receiving bore with an opening on one end for receiving said collet member and having an internal diameter such that as said collet member, with an electrical conductor disposed therein between said facing surfaces of said jaws, is slid into said bore, said jaws are squeezed together by interaction with said bore with a pressure to cause said jaws to electrically conductively engage said conductor, continued insertion of said collet member into said bore, as a result of interaction with said bore, plastically deforming the material of said collet member adjacent said jaws to maintain the jaws in electrically conductive engagement with the conductor and to retain said collet member in said bore.

Claim 12

An electrical connector comprising: (a) a cylindrical collet member of an electrically conductive material and having jaws at one end facing into a central bore, said member being adapted to have an electrical conductor disposed within said bore between facing surfaces of said jaws; and (b) a plug housing of an electrically conductive material defining a collet member receiving bore with an opening on one end for receiving said collet member and having an internal diameter such that as said collet member, with an electrical conductor disposed therein between said facing surfaces of said jaws, is slid into said bore, said jaws are squeezed together by interaction with said bore with a pressure to cause said jaws to electrically conductively engage said conductor, continued insertion of said collet member into said bore, as a result of interaction with said bore, plastically deforming the material of said collet member adjacent said jaws to maintain the jaws in electrically conductive engagement with the conductor and to retain said collet member in said bore.
