Problems solved by technology

However, the existing leakage protection plugs are only waterproof and moisture-proof through the shell, and the protection of the plug itself is insufficient. Water vapor entering the plug may damage the plug, causing the plug to fail to reset after power failure or the plug cannot play the role of leakage protection, affecting the plug. normal use

Abstract

The invention relates to a leakage protection plug which comprises a housing, a lead, a leakage protection module arranged in the housing, a two-power-supply plug pin and a grounding plug pin. The two-power-supply plug pin and the grounding plug pin are connected with the leakage protection module, the housing is wrapped with a rubber sleeve, a reset button hole and a test button hole are respectively formed in a corresponding reset button and a corresponding test button on the housing, the reset button is wrapped with a reset sleeve made of rubber, the upper end of the reset sleeve tightly penetrates into the reset button hole, the test button is made of rubber, and the upper end of the test button tightly penetrates through the test button hole. The rubber sleeve is arranged outside the housing in an injection molding mode to play an insulating water-proofing role.

Description

technical field [0001] The invention relates to a plug, in particular to a leakage protection plug. Background technique [0002] With the increasing popularity of industrial production facilities and household appliances, people have more and more opportunities to come into contact with electricity, and the failure of electrical equipment leads to electric shock casualties. For personal safety and equipment safety, leakage protector has been widely used as an effective electrical safety technology device, and has played a pivotal role. Based on the principle of leakage protector, in order to provide better protection for users, many products are now equipped with leakage protection plugs. When the electrical equipment connected to the leakage protection plug leaks, the leakage protection plug can be automatically cut off within tens of milliseconds The power supply protects users from the danger of electric shock and protects their lives. [0003] Leakage protection plugs...
