Description

Technical Field

[0001] The utility model relates to the technical field of lighting fixtures, in particular to a lamp cap. Background Art

[0002] A lamp cap refers to the interface connected to the end of an electric lamp wire for installing a light bulb. It is the end of the light bulb and also the connection part between the light source and the external power supply. The light source is powered through the lamp cap to generate a lighting phenomenon. There are various types of lamp caps, including plastic bakelite lamp caps, ceramic lamp caps, metal lamp caps, and wooden lamp caps, etc. There are also various wiring methods for lamp caps, such as riveting type, locking type, plugging type, and twin type, etc.

[0003] After the lamp cap is used for a long time, the copper sheets or copper rings in the lamp cap are prone to faults such as oxidation. When the copper sheets or copper rings malfunction, new lamp caps are directly replaced at home. However, in some places such as enterprises where there are more lamps used, directly replacing the lamp cap will increase the cost. Directly replacing the copper sheets or copper rings can effectively reduce the cost. However, when replacing the copper sheets and copper rings, it is more inconvenient to replace, making the repair and replacement process of the copper sheets and copper rings too difficult.
