Abstract
Abstract A moulded socket for electric lamp bulbs comprising a hollow cylindrical body and an open end. An electrical cable is moulded within a base formed integrally with the cylindrical body. A center metal contact is partly moulded within the base and held at the center of the socket over the base. A U-shape metal side contact having two opposed sides and a connecting base is also partly moulded within the cylindrical body and adapted to receive and retain a lamp bulb screw base between the opposed sides. Points are formed with the contacts to penetrate the insulation on the electrical cable to make electrical connection with a respective wire. The base of the socket is provided with ventilating holes and guide ribs are formed in the inner surface of the cylindrical body to guide a screw base in the socket and to provide sufficient ventilation thereabout. A holding clip is also moulded, at one end thereof, within the socket base.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
266 words
An electrical lamp socket for lamp bulbs having a screw base, said lamp socket comprising a hollow cylindrical body having an open end and closed at the opposite end by a socket base integrally moulded with said cylindrical body, an electrical cable having two insulated conductor wires, said cable being moulded within said socket base, a center metallic contact having a contacting portion disposed substantially at the center of the inner face of said socket base, a retaining base portion integrally formed with said contact surface and moulded within said base to rigidly secure said center contact in said lamp socket and a point in the lower edge of said retaining base portion and penetrating said cable to contact one of said two wires, a metallic side contact of generally U-shape configuration having two opposed vertical sides and a connecting base, said side contact being partly embedded within said hollow cylindrical body and having undulations in the inner edge of each of said opposed vertical sides to engage and retain the screw base of a lamp bulb in said hollow cylindrical body and a point integrally formed in the lower edge of said connecting base and also penetrating said cable to contact said other one of said two wires, a holding clip having a fixed end and a free end, said fixed end being provided with anchoring means which are moulded within said socket base to retain a portion adjacent said free end against the outer surface of said hollow cylindrical body to thereby retain a holding element between said holding clip and said cylindrical body.
Claim 2
Dependent Claim
266 words
An electrical lamp socket for lamp bulbs having a screw base, said lamp socket comprising a hollow cylindrical body having an open end and closed at the opposite end by a socket base integrally moulded with said cylindrical body, an electrical cable having two insulated conductor wires, said cable being moulded within said socket base, a center metallic contact having a contacting portion disposed substantially at the center of the inner face of said socket base, a retaining base portion integrally formed with said contact surface and moulded within said base to rigidly secure said center contact in said lamp socket and a point in the lower edge of said retaining base portion and penetrating said cable to contact one of said two wires, a metallic side contact of generally U-shape configuration having two opposed vertical sides and a connecting base, said side contact being partly embedded within said hollow cylindrical body and having undulations in the inner edge of each of said opposed vertical sides to engage and retain the screw base of a lamp bulb in said hollow cylindrical body and a point integrally formed in the lower edge of said connecting base and also penetrating said cable to contact said other one of said two wires, a holding clip having a fixed end and a free end, said fixed end being provided with anchoring means which are moulded within said socket base to retain a portion adjacent said free end against the outer surface of said hollow cylindrical body to thereby retain a holding element between said holding clip and said cylindrical body.
Claim 3
Dependent Claim
266 words
An electrical lamp socket for lamp bulbs having a screw base, said lamp socket comprising a hollow cylindrical body having an open end and closed at the opposite end by a socket base integrally moulded with said cylindrical body, an electrical cable having two insulated conductor wires, said cable being moulded within said socket base, a center metallic contact having a contacting portion disposed substantially at the center of the inner face of said socket base, a retaining base portion integrally formed with said contact surface and moulded within said base to rigidly secure said center contact in said lamp socket and a point in the lower edge of said retaining base portion and penetrating said cable to contact one of said two wires, a metallic side contact of generally U-shape configuration having two opposed vertical sides and a connecting base, said side contact being partly embedded within said hollow cylindrical body and having undulations in the inner edge of each of said opposed vertical sides to engage and retain the screw base of a lamp bulb in said hollow cylindrical body and a point integrally formed in the lower edge of said connecting base and also penetrating said cable to contact said other one of said two wires, a holding clip having a fixed end and a free end, said fixed end being provided with anchoring means which are moulded within said socket base to retain a portion adjacent said free end against the outer surface of said hollow cylindrical body to thereby retain a holding element between said holding clip and said cylindrical body.
Claim 4
Dependent Claim
266 words
An electrical lamp socket for lamp bulbs having a screw base, said lamp socket comprising a hollow cylindrical body having an open end and closed at the opposite end by a socket base integrally moulded with said cylindrical body, an electrical cable having two insulated conductor wires, said cable being moulded within said socket base, a center metallic contact having a contacting portion disposed substantially at the center of the inner face of said socket base, a retaining base portion integrally formed with said contact surface and moulded within said base to rigidly secure said center contact in said lamp socket and a point in the lower edge of said retaining base portion and penetrating said cable to contact one of said two wires, a metallic side contact of generally U-shape configuration having two opposed vertical sides and a connecting base, said side contact being partly embedded within said hollow cylindrical body and having undulations in the inner edge of each of said opposed vertical sides to engage and retain the screw base of a lamp bulb in said hollow cylindrical body and a point integrally formed in the lower edge of said connecting base and also penetrating said cable to contact said other one of said two wires, a holding clip having a fixed end and a free end, said fixed end being provided with anchoring means which are moulded within said socket base to retain a portion adjacent said free end against the outer surface of said hollow cylindrical body to thereby retain a holding element between said holding clip and said cylindrical body.
Claim 5
Dependent Claim
