Abstract
Abstract An improved sealed beam glass PAR lamp design is disclosed which employs a particular ferrule construction permitting electrical wire conductors to be connected thereto without soldering or screw terminals. The improved termination features physical engagement between the ferrule member and a metal contact element having flexible fingers to grip an inverted tapered wall section of said ferrule member.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
151 words
An improved sealed beam glass PAR lamp having a glass reflector member, metal ferrule members sealed to a plurality of raised bosses formed on the rear surface of said glass reflector member, each of said ferrule members having a cylindrical body terminating in an inverted tapered head of smaller diameter, and electrical termination means engaged to the inverted tapered head portion of each ferrule member solely by a physical gripping action wherein the improvement comprises having each electrical termination means project rearwardly from each ferrule member by means of utilizing a dome-shaped metal contact element having flexible fingers to engage the inverted tapered head of the ferrule, said dome-shaped metal contact being located at one end of a cylindrical shank having a larger diameter collar at its opposite end, and with said collar engaging a terminal element with means to connect a wire conductor directly thereto by a physical gripping action.
Claim 2
Dependent Claim
151 words
An improved sealed beam glass PAR lamp having a glass reflector member, metal ferrule members sealed to a plurality of raised bosses formed on the rear surface of said glass reflector member, each of said ferrule members having a cylindrical body terminating in an inverted tapered head of smaller diameter, and electrical termination means engaged to the inverted tapered head portion of each ferrule member solely by a physical gripping action wherein the improvement comprises having each electrical termination means project rearwardly from each ferrule member by means of utilizing a dome-shaped metal contact element having flexible fingers to engage the inverted tapered head of the ferrule, said dome-shaped metal contact being located at one end of a cylindrical shank having a larger diameter collar at its opposite end, and with said collar engaging a terminal element with means to connect a wire conductor directly thereto by a physical gripping action.
Claim 3
Dependent Claim
37 words
An improved PAR lamp as in claim 1 wherein a pair of metal ferrules are employed and the contact elements are joined together with a strip of electrical insulation that serves to physically support the termination means.
Claim 4
Dependent Claim
22 words
An improved PAR lamp as in claim 1 wherein the terminal element is electrically connectable to the wire conductor by crimping action.
Claim 5
Dependent Claim
30 words
An improved PAR lamp as in claim 1 wherein the terminal element includes means to pierce the insulation of an insulated wire conductor when electrically connected thereto by crimping action.
Claim 6
Dependent Claim
44 words
An improved PAR lamp as in claim 1 wherein the ferrule members have a cylindrical body terminating in an inverted tapered head of smaller diameter and with said tapered head having an annular rim joined to the cylindrical body by a recessed wall section.
