Lamp cap and method of manufacturing thereof
View Patent ↗A lamp cap ( 100 ) comprising a base part ( 101 ) defining a cavity ( 102 ) for receiving a socket ( 203 ) of a lamp, the base part ( 101 ) having a lateral wall arrangement ( 103 ) limiting the cavity ( 102 ) and a ring shaped bottom side ( 104 ) surrounding an aperture ( 105 ); an electrical insulating interface ( 106 ) fixed to the bottom side of the base part ( 104 ) in such a manner that it covers the aperture ( 105 ), a space ( 102 ) being defined between the electrical insulating interface ( 106 ) and the lateral wall arrangement ( 103 ); and an electrical connector assembly ( 120 ) extending through the electrical insulating interface ( 106 ) to provide an electrical connection between the lamp socket ( 203 ) and an electrical power supply. A method of and apparatus for manufacturing a lamp cap is also described.
1. A lamp cap comprising:
a base part defining a cavity for receiving a socket of a lamp through a first side along a main axis of the lamp cap, the base part having a lateral wall arrangement limiting the cavity and a ring shaped second opposing side surrounding an aperture;
an electrical insulating interface inserted and affixed to the second side of the base part in such a manner that it covers the aperture, a gap being provided between the electrical insulating interface and the lateral wall arrangement; and
electrical connectors extending at least partly through the electrical insulating interface to provide an electrical connection between the lamp socket and an electrical power supply.
2. A lamp cap according to claim 1 , wherein the electrical insulating interface is sealed to the second side of the base part.
3. A lamp cap according to claim 1 , further comprising referencing means for positioning the lamp cap during manufacturing and/or fitting of the lamp cap.
4. A lamp cap according to claim 3 , wherein the referencing means is provided by a pair of opposing planar surfaces of the lateral wall arrangement of the base part.
5. A lamp cap according to claim 1 , wherein the electrical connectors comprises a first and second electrical connectors, each electrical connector including: a first end portion for providing an electrical connection with an electrical power supply, a second end portion for providing an electrical connection with the lamp, the second end portion being disposed closer to said main axis than the first end portion; and an intermediate portion extending between the first end portion and the second end portion within the electrical insulating interface.
6. A lamp cap according to claim 5 , wherein each second end portion is provided with a cone shaped aperture for receiving a corresponding electrical connecting element of the lamp.
7. A lamp cap according to claim 5 , wherein the first end portion extends mainly from the electrical insulating interface in a direction away from the first side of the cavity, and the second end portion is arranged within the electrical insulating interface with an access from the cavity being provided for connecting with the lamp.
8. A lamp cap according to claim 5 , wherein at least one electrical connector further comprises a S-shaped portion extending within the electrical insulating interface from said first end portion to a terminal part of the S-shaped portion such that this terminal part is closer to said main axis than the first end portion.
9. A lamp cap according to claim 1 , wherein the base part comprises a flange extending around a major portion of the base part for positioning the lamp cap in a lamp holder.
10. A lamp cap comprising a support ring for receiving a socket of a lamp through a first side, the support ring having an inner wall defining a cavity and a second opposing side surrounding an aperture; an electrical insulator fixed to the second side of the support ring to cover the aperture, a gap being provided between the electrical insulator and the inner wall of the support ring, and an electrical connector extending through the electrical insulator to provide an electrical connection between the lamp socket and an electrical power supply.
