Abstract

Abstract A spark plug terminal having an initially tubular body portion between its ends is provided with an axially elongated indentation in one side thereof, the maximum depth of the groove being such that the inner surface of the indentation bears against the inner surface of the diametrically opposed side of the body portion and the width of the indentation being such that the sides of the latter engage the corresponding sides of the body portion. The body portion may remain axially straight or it may be bent between its ends to form an elbow, the direction of bending being such that the groove is at the inside of the elbow. One end of the terminal is provided with means for attaching it to a conductor and the opposite end of the terminal is provided with means for connecting it to the electrode of a spark plug. A sleeve or boot of dielectric material is assembled with the terminal.

Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 162 words
An electrical terminal comprising an uninterrupted tubular, electrically conductive body and connector means at opposite ends of said body for connection to electrical terminals, said connector means being notched adjacent the opposite ends of said body, said body being deformed radially inwardly thereof between its ends and from one side of said body toward the opposite side thereof to form an elongate, axially arcuate indentation of less width than the diametral dimension of said body, said indentation having a bottom and opposed sides, the bottom of said indentation at its deepest point being in face to face engagement with the opposite side of said body and the opposed sides of said indentation at said deepest point being in face to face engagement with the respective adjacent sides of said body, whereby the entire deformed wall portion of said indentation at the deepest point thereof is in face to face engagement with the entire undeformed wall portion of said body at said point.
Claim 2
Dependent Claim 162 words
An electrical terminal comprising an uninterrupted tubular, electrically conductive body and connector means at opposite ends of said body for connection to electrical terminals, said connector means being notched adjacent the opposite ends of said body, said body being deformed radially inwardly thereof between its ends and from one side of said body toward the opposite side thereof to form an elongate, axially arcuate indentation of less width than the diametral dimension of said body, said indentation having a bottom and opposed sides, the bottom of said indentation at its deepest point being in face to face engagement with the opposite side of said body and the opposed sides of said indentation at said deepest point being in face to face engagement with the respective adjacent sides of said body, whereby the entire deformed wall portion of said indentation at the deepest point thereof is in face to face engagement with the entire undeformed wall portion of said body at said point.
Claim 3
Dependent Claim 15 words
A terminal according to claim 1 wherein said indentation is arcuate transversely of said body.
Claim 4
Dependent Claim 27 words
A terminal according to claim 1 wherein said body is bent between its ends to form an elbow, said indentation being at the insIde of the elbow.
Claim 5
Dependent Claim 16 words
A terminal according to claim 3 wherein said body forms an included angle of substantially 90*.
Claim 6
Dependent Claim 16 words
A terminal according to claim 3 wherein said body forms an included angle of substantially 110*.
Claim 7
Dependent Claim 16 words
A terminal according to claim 3 wherein said body forms an included angle of substantially 130*.
Claim 8
Dependent Claim 25 words
A terminal according to claim 1 wherein said body is split longitudinally, said split and said indentation being located on opposite sides of said body.
Claim 9
Dependent Claim 24 words
A terminal according to claim 1 wherein said body is split longitudinally, said split and said indentation being spaced substantially 90* from one another.
Claim 10
Dependent Claim 18 words
A terminal according to claim 1 wherein said body is substantially cylindrical in cross-section except for said indentation.
Claim 11
Dependent Claim 20 words
A terminal according to claim 1 wherein said body forms an included angle greater than 130*. and less than 180*.
Claim 12
Independent Claim 153 words
A method of making an electrical terminal having between its ends a cylindrical, elongate body formed of electrically conductive material, aid method comprising deforming one side of said body between its ends radially inwardly of said body toward the opposite side thereof to form an elongate, axially arcuate indentation having a predetermined radius such that the deepest point of said indentation is in face to face engagement with the opposite side of said body, said indentation being of such width that at said deepest point thereof the opposed sides of said indentation are in face to face engagement with the respective ajdacent sides of said body; and bending said body at said deepest point of said indentation about a radius less than said predetermined radius to form an elbow between the ends of said body, the direction of bending said body being such that said indentation is at the inside of said elbow.
Claim 13
Independent Claim 153 words
A method of making an electrical terminal having between its ends a cylindrical, elongate body formed of electrically conductive material, aid method comprising deforming one side of said body between its ends radially inwardly of said body toward the opposite side thereof to form an elongate, axially arcuate indentation having a predetermined radius such that the deepest point of said indentation is in face to face engagement with the opposite side of said body, said indentation being of such width that at said deepest point thereof the opposed sides of said indentation are in face to face engagement with the respective ajdacent sides of said body; and bending said body at said deepest point of said indentation about a radius less than said predetermined radius to form an elbow between the ends of said body, the direction of bending said body being such that said indentation is at the inside of said elbow.
Claim 14
Dependent Claim 19 words
A method according to claim 11 wherein the bending of said body forms an included angle less than 180*.
Claim 15
Dependent Claim 26 words
A method according to claim 11 wherein said body is bent about an arc having its center at the center of the arc of said indentation.
Claim 16
Dependent Claim 27 words
A method according to claim 11 wherein the depth of said indentation corresponds to the inside diameter of said body less the wall thickness of said body.
Claim 17
Dependent Claim 23 words
A method according to claim 11 wherein the bending of said body forms an included angle of between about 90* and about 130*.
