Plastic lamp holder

Abstract

The invention aims at providing an energy-saving plastic lamp holder. An injection mold which is capable of injecting the lamp holder and a plastic piece on an energy-saving lamp together is arranged according to E40, E27, E26, E14 and B22 type lamp holders which are conventionally used internationally and domestically, so that the lamp holder and the plastic piece on the energy-saving lamp can be combined and injected into a whole. Then a pore is reserved in the midst of the top of the molded plastic lamp holder and in the middle waist part of the lamp holder respectively for the E type lamp holders, and is used for connecting a lead wire on a circuit board of the energy-saving lamp with an input power supply; two pores are reserved on the top of the molded plastic lamp holder for the B type lamp holder, and are used for connecting two lead wires on the circuit board of the energy-saving lamp with positive and negative poles of the input end of a power supply, so that the novel energy-saving plastic lamp holder. After the novel plastic lamp holder is adopted, both the qualification rate of products and productivity effect can be improved on producing process and producing link, so the lamp holder is a great technical revolution for lighting industry.

Description

[0001] Field [0002] The invention relates to a plastic lamp cap for lighting, in particular to a plastic lamp cap for energy-saving lamp lighting. Background technique [0003] At present, the lighting lamp holders used by electric light sources are made of nickel-plated iron or galvanized lamp holders. In the production process, the lamp holders are screwed on the plastic parts of the energy-saving lamps and combined with each other. The use of this lamp holder has the following defects: first The equipment is complicated and costly when manufacturing the lamp cap, and at the same time, the gold-plating process is used, which causes great pollution to the environment; secondly, the process of assembling energy-saving lamps using this lamp cap is cumbersome, and the production process of screwing the lamp cap, welding the lamp cap, and riveting the lamp cap is required. , not only affects the output but also affects the quality of the product; thirdly, the welding connection...

Problems solved by technology

[0003] At present, the lighting lamp holders used by electric light sources are made of nickel-plated iron or galvanized lamp holders. In the production process, the lamp holders are screwed on the plastic parts of the energy-saving lamps and combined with each other. The use of this lamp holder has the following defects: first The equipment is complicated and costly when manufacturing the lamp cap, and at the same time, the gold-plating process is used, which causes great pollution to the environment; secondly, the process of assembling energy-saving lamps using this lamp cap is cumbersome, and the production process of screwing the lamp cap, welding the lamp cap, and riveting the lamp cap is required. , not only affects the output but also affects the quality of the product; thirdly, the welding connection method is used in the production process of the welding lamp cap, which will easily cause the flux in the solder wire to flow out to the surface of the lamp cap during operation, thereby causing corrosion and rust on the lamp cap and affecting the product. The quality of the lamp holder is high, although the welding-free environmentally friendly lamp holder is also used today, but the problem has not been fundamentally solved. Therefore, how to change the production process of the lamp holder is a new topic in the energy-saving lamp industry.
