Abstract
Abstract The terminal is stamped from a thin sheet of metal and rolled into a cylindrical sleeve which is bent at the center to have the adjacent sections disposed at an angle of approximately 110* to each other after the wires of a conductor have been inserted in the end with the two sections retained in angular relation by locking fingers. The terminal is encased in an elastomeric tube before it is bent and the memory therein aids in retaining the terminal sections in locked angular relation.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
56 words
In a spark plug terminal, a cylindrical sleeve having cutout portions in the edges to provide a central bendable web joining a spark plug receiving section and a conductor-receiving section, and locking means at the adjacent ends of the sections which interengage when the two sections are moved into angle relationship to lock the sections thereat.
Claim 2
Dependent Claim
56 words
In a spark plug terminal, a cylindrical sleeve having cutout portions in the edges to provide a central bendable web joining a spark plug receiving section and a conductor-receiving section, and locking means at the adjacent ends of the sections which interengage when the two sections are moved into angle relationship to lock the sections thereat.
Claim 3
Dependent Claim
31 words
In a spark plug terminal as recited in claim 1, wherein said locking means are extending fingers on one section aligned with apertures at the adjacent end of the other section.
Claim 4
Dependent Claim
71 words
In a spark plug terminal as recited in claim 2, wherein the portion of the section having the apertures therein is deflected inwardly to provide a cam surface for guiding the fingers into the apertures. 4. In a spark plug terminal as recited in claim 2, wherein the cylindrical sleeve is rolled from a flat stamped sheet to have mating edges along the side opposite to that containing said bendable web.
Claim 5
Dependent Claim
62 words
In a spark plug terminal as recited in claim 4, wherein the outer end of the conductor-receiving section has inwardly extending locking nibs in the U-shaped web and extending sides thereof for receiving a conductor and forcing the nibs into the elastomeric sleeve of the conductor by bending said sides there around while the sections are in aligned relation to each other.
Claim 6
Dependent Claim
29 words
In a spark plug terminal as recited in claim 5, wherein the nibs are provided in rows on inwardly extending transverse ribs in the U-shaped web and extending sides.
Claim 7
Dependent Claim
48 words
In a spark plug terminal as recited in claim 4, wherein the spark plug receiving section has recesses extending into the abutting edges in offset relation to each other and aligned with projecting fingers on the offset edges which extend into said recesses to span the abutting edges.
Claim 8
Dependent Claim
40 words
In a spark plug terminal as recited in claim 7, wherein the inner portion of the recesses are of greater width and wherein the ends of the fingers projecting from the edges are wider to provide an interlocking relation therebetween.
Claim 9
Dependent Claim
30 words
In a spark plug terminal as recited in claim 7, wherein sleeve means at the end portion of the spark plug receiving end extends over said aligned fingers and recesses.
Claim 10
Dependent Claim
37 words
In a spark plug terminal as recited in claim 5, wherein said terminal is encased within an elastomeric tube before said tube and terminal are bent as unit to have the end sections disposed in angular relation.
