Abstract
An improved terminal pin for use with the bi-pin type end caps of fluorescent discharge tubes to reduce electrical shock hazards is disclosed. The pin comprises a body portion, a tip portion of reduced thickness relative to that of the body portion, and insulation covering the tip portion. The end cap utilizing the subject terminal pin is compatible with conventional lamp sockets.
Claims12
The terminal pin of electrically conducting material for use with end caps of fluorescent discharge tubes and the like comprising:
- an elongated pin body portion;
- a tip portion extending from an end of said body portion, said tip portion having a reduced thickness with respect to that of said body portion;
- and
- insulation covering substantially all the exterior surface of said tip portion.
The terminal pin for use with end caps of fluorescent discharge tubes and the like comprising:
- a hollow, elongated pin body having a circular cross-section, divided into a first body portion and a second body portion by an encircling boss;
- a tip portion extending from an end of said body portion, said tip portion having a reduced thickness with respect to that of said body portion, and further including an encircling projection;
- and
- non-conducting insulating material covering substantially the entire exterior surface of said tip portion.
The connector end cap for fluorescent discharge tubes and the like comprising:
- disc member having an annular flange disposed around the periphery thereof;
- a pair of openings formed in said disc member;
- a pair of terminal pins, one each inserted through each of said openings, each of said pins having an elongated body portion and a tip portion extending from an end of said body portion having a reduced thickness with respect to that of said body portion;
- insulation for covering substantially all the exterior surface of said tip portion;
- and means for securing said pin in said opening;
- whereby the electrical elements within said tube may be electrically coupled to said pins for connection to a source of electrical energy, and said insulation reduces the electrically conducting surface area of said pin exposed to persons handling such tubes.
