Abstract
Abstract A connector for electrically connecting a power source to a glow plug. An electrically conductive cylindrical housing encloses an insulated central conductor which is spring biased toward one end of the cylinder. The open end of the cylinder is formed to fit over the nut of a typical glow plug and permit the connector to be easily manipulated to a locked, vibrationless electrical contact with the glow plug.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
145 words
A connector, comprising in combination: a cylindrical, electrically conductive housing, electrode means slidably disposed within said housing, spring means normally biasing said electrode means toward one end of said housing, said electrode means comprising an electrically insulating plunger slidably disposed within said housing, said plunger having a longitudinal bore therethrough, a first electrically conductive tube fixedly disposed within said bore, said one end of said housing pierced to form a hexagonal opening therein, a plurality of indentations formed in the wall at said one end of said housing with adjacent indentations forming recesses therebetween, each point of said hexagonal opening alligned with one of said recesses, at least one of said indentations extended upward in said wall and located between adjacent points of said hexagonal piercing, said plunger having a shoulder near one end therof normally held against said extended indentation by said spring means.
Claim 2
Dependent Claim
145 words
A connector, comprising in combination: a cylindrical, electrically conductive housing, electrode means slidably disposed within said housing, spring means normally biasing said electrode means toward one end of said housing, said electrode means comprising an electrically insulating plunger slidably disposed within said housing, said plunger having a longitudinal bore therethrough, a first electrically conductive tube fixedly disposed within said bore, said one end of said housing pierced to form a hexagonal opening therein, a plurality of indentations formed in the wall at said one end of said housing with adjacent indentations forming recesses therebetween, each point of said hexagonal opening alligned with one of said recesses, at least one of said indentations extended upward in said wall and located between adjacent points of said hexagonal piercing, said plunger having a shoulder near one end therof normally held against said extended indentation by said spring means.
Claim 3
Dependent Claim
52 words
A connector according to claim 1 further comprising, a second electrically conductive tube having one end secured to said second lead, the other end of said second tube slidably disposed within one end of said first tube, said second tube adapted to move within said second tube in physically contacting relationship therewith.
Claim 4
Dependent Claim
21 words
A connector according to claim 2 wherein said first tube has a plurality of crimps formed in the other end thereof.
Claim 5
Dependent Claim
40 words
A connector according to claim 3 further comprising, a spring disposed within said first tube, one end of said spring abutting against said crimps and the other end of said spring abutting against said other end of said second tube.
Claim 6
Dependent Claim
50 words
A connector according to claim 4 wherein said plunger is of such a length relative to said housing that it can move within said housing such that said one end clears said plurality of indentations and said other end of said second tube never breaks contact with said first tube.
