Description

Technical Field

[0001] The present application relates to the field of insulating lighting equipment, and in particular to an insulating flashlight. Background Art

[0002] Whether it is the manufacturing and maintenance of various types of electric power, new energy vehicles, electronic products or precision equipment, the power supply cannot be completely cut off due to various reasons. Therefore, when using tools to repair these energized production equipment, it is necessary to ensure the electrical insulation performance of the tools used to improve safety.

[0003] In addition to general tools such as torque wrenches and screwdrivers, lighting tools such as flashlights also need to ensure good insulation performance. On the one hand, flashlights usually have batteries and circuits inside, and these components are very sensitive to the flow of current. Without proper insulation measures, the battery may short-circuit and the circuit may be damaged, which will not only affect the normal use of the flashlight, but may also cause fire or other safety issues. Insulation materials can protect these key components from the external environment and ensure the safe and stable operation of the flashlight. On the other hand, flashlights are usually made of metal and other conductive materials, which may conduct electricity when used improperly. Ensuring the insulation performance of the flashlight can ensure that the flashlight's shell and internal circuit will not become a carrier of current, thereby greatly reducing the risk of electric shock.

[0004] For common flashlights that use replaceable batteries, the insulation performance of the flashlight can be basically ensured by simply using an insulating shell or coating the flashlight shell with insulating materials and replacing the switch components with insulating materials. However, more and more flashlights are currently using built-in batteries and equipped with charging functions. These rechargeable flashlights are easy to charge and have low cost of use, so they are widely popular. Correspondingly, the charging port of a flashlight with a charging function also needs to ensure insulation performance and not have too much impact on the overall structural coordination and ease of use of the flashlight.
