Abstract
Abstract A conductive metal terminal with contact making portions extending above and below a metal panel. A two-piece insulating assembly permits the terminal to be inserted into a hole in the metal panel. Then, upon application of a tool, the bottom half of the insulator assembly is forced toward the panel and locks the terminal into place. The bottom half of the insulator is retained in its locked position by barb-like annular flanges. The top half of the insulator rests against a flanged head on the metal terminal.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
110 words
An insulated terminal assembly for mounting within a hole a panel comprising: a first insulator bushing formed of resilient deformable material and provided with an axiAl hole therethrough and an external shoulder for limiting against the panel surface; a conductive shaft positioned in the hole and having a disk shoulder making contact with the top surface of the insulator, said shaft including a plurality of barb-like flanges on the shaft; a second insulator bushing also made of a resilient deformable material positioned around the lower portion of the first insulator for forced engagement with some of said barb-like flanges and for clamping action with the bottom surface of the panel.
Claim 2
Dependent Claim
110 words
An insulated terminal assembly for mounting within a hole a panel comprising: a first insulator bushing formed of resilient deformable material and provided with an axiAl hole therethrough and an external shoulder for limiting against the panel surface; a conductive shaft positioned in the hole and having a disk shoulder making contact with the top surface of the insulator, said shaft including a plurality of barb-like flanges on the shaft; a second insulator bushing also made of a resilient deformable material positioned around the lower portion of the first insulator for forced engagement with some of said barb-like flanges and for clamping action with the bottom surface of the panel.
Claim 3
Dependent Claim
24 words
The assembly of claim 1 wherein said shaft has a knurled portion for contact with the hole surface of said insulator with a shoulder.
Claim 4
Dependent Claim
26 words
The assembly of claim 1 wherein one of the ends of said shaft is formed with a bifurcated portion to aid in securing a conductive wire.
Claim 5
Dependent Claim
41 words
The assembly of claim 1 wherein said first insulator is formed with a tapered outside surface below the panel hole, said second insulator being adapted to ride over the tapered portion when the second insulator is forced into a clamped position.
Claim 6
Dependent Claim
19 words
The assembly of claim 1 wherein the upper edge of the second insulator is formed with a reentrant chamfer.
Claim 7
Dependent Claim
36 words
The assembly of claim 1 wherein the upper edge of the second insulator is formed with a flat end, the surface of which is substantially at right angles to the outside surface of the second insulator.
