There are also head barrels connected together or the barrel body and the tail cover are connected together. For the lighting equipment with the tail cover and the barrel separated, There are two kinds of conduction methods: thread conduction and tail end face conduction. Both conduction methods have their own advantages and disadvantages. For the threaded conductive structure, since the conductive surface cannot be oxidized, the material body can only be exposed. The barrel body and tail cover need to replace the battery. After a long time of rotation and friction, the worn surface of the material will lose slag and turn black, which affects the appearance and is not good. For the end face conduction, in addition to the end face conduction which cannot be oxidized, the thread will be oxidized. After oxidation, the surface hardness of the product will increase and the friction resistance will be greatly increased, but the end face conduction has defects, and it is slightly loose, which is easy to cause poor contact.
