Crimp-type terminal
First Claim
1. The combination of a single cable and a terminating means crimped around said single cable for terminating said single cable, in which said terminating means comprises:
- a barrel-shaped outer wall having a convex inner surface and an open seam extending axially along the length thereof; and
an inner wall adjacent to said outer wall and having a concave inner surface;
said inner wall comprising first and second sections each having inner surfaces and each having first and second oppositely positioned edges and each integrally connected at said first edge to said outer wall along one side of said open seam and folded from said open seam towards each other upon said inner surface of said outer wall;
said single cable having a perimeter with first and second portions;
said outer and inner walls crimped around first and second portions of the perimeter, respectively, of said single cable;
the inner surfaces of said first and second sections of said inner wall physically engaging said first and second portions of said single cable and pressing said first and second portions of said single cable therewithin and against each other.

Abstract
A crimpable terminal device in which the barrel is double walled, with the inner wall being formed from the same sheet of metal as the outer wall and being integral therewith. Specifically, the inner wall is formed by folding over extensions of the outer wall back upon the inner surface of the inner wall and then forming the resulting double thickness of metal into a barrel within which a wire is placed and the barrel crimped thereupon. The inner wall of the barrel can have slots or apertures therein or other irregular surfaces, all designed to bite into the conductor crimped therein to make good electrical and mechanical connection therewith. Because the inner wall has slots formed completely therethrough, and further because the inner wall can move relatively freely with respect to the outer wall, the crimping produces unusually good electrical and mechanical connections and with many side benefits.

22. The combination of a single conductive cable and terminating means for terminating said single conductive cable, with said terminating means comprising:
-
a barrel formed from an integral sheet of metal; said barrel having walls comprised of at least two layers of metal with adjacent layers being in contact with each other over most of at least one major surface thereof; said at least two layers comprising an open seam outer layer with a concave inner surface and an inner layer having first and second terminating edges; said inner layer comprising first and second extensions of said outer layer originating at the open seam thereof and which are folded over at said open seam and extend back upon the concave inner surface of said outer layer towards each other for predetermined distances; said single conductive cable comprising a perimeter having first and second oppositely positioned portions; said barrel being crimped around said single conductive cable; said inner surfaces of said first and second extensions of said outer layer which form said inner layer being in physical contact with said opposite perimetric surfaces of said single conductive cable to maintain inwardly directed radial forces around the perimeter of said single conductive cable contained therebetween. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)

39. The combination of a single conductor and a double walled, barrel-shaped terminating means for terminating said single conductor, said double walled, barrel-shaped terminating means comprising:
-
an outer wall having an open seam substantially parallel to the axis of said barrel and defining the first and second circumferentially terminating edges of said outer wall; and an inner wall comprising a first section and a second section each having an outer surface and an inner surface; said first section of said inner wall being an integral extension of said first terminating edge of said outer wall and folded back within said outer wall with its outer surface laying upon the inside surface of said outer wall and extending along said inside surface of said outer wall a predetermined distance; said second section of said inner wall being an integral extension of said second terminating edge of said outer wall and folded back within said outer wall with its outer surface laying upon the inside surface of said outer wall and extending along the inside surface of said outer wall a second predetermined distance; said single conductor having a perimeter with oppositely positioned surfaces; said outer and inner walls crimped around said oppositely positioned surfaces of said single conductor with the inner surfaces of said first and second sections of said inner wall pressing against oppositely positioned surfaces of said single conductor to make electrical and mechanical contact therewith. - View Dependent Claims (40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59)
