Problems solved by technology

[0002] With the rapid development of the national economy, convenient vehicles such as automobiles are favored by people. At present, the commonly used automobile terminals in China are generally R-type or Y-type terminals. This type of terminal wiring is exposed in the air and has no waterproof insulation function. When the car line is soaked in water, it is likely to cause the car to fail to restart after a short circuit; the current solution to this problem is to wrap a heat-shrinkable sleeve around the terminal, and then seal it by welding, but the heat-shrinkable sleeve is not waterproof. , and the appearance is not beautiful after shrinking, and it is not easy to operate; in addition, in the field of outdoor wiring for automation equipment such as locomotives and outdoor advertisements, due to the weather, ordinary terminals cannot be used, and heat shrinkable tubes also have limitations in use.
