A waterproof plug

Abstract

The invention discloses a waterproof patch board. The waterproof patch board comprises a shell and power supply inserting cabins arranged on the shell, wherein a starting conductive element is arranged in each power supply inserting cabin; each starting conductive part comprises a fixed connecting end which passes through the bottom of the corresponding power supply inserting cabin and an elastic clamping sheet fixedly connected with the corresponding fixed connecting end; magnets I are arranged outside the elastic clamping sheet; a strong-current circuit connecting piece connected with the fixed connecting ends, a weak-current circuit connecting assembly I, a weak-current circuit connecting assembly II and a controllable switch module are arranged in the shell; the weak-current circuit connecting assembly I is provided with elastic sheets; the elastic sheets are provided with contacts I and magnets II; and the magnets II and the magnets I are corresponding in positions. According to the waterproof patch board provided by the invention, the starting conductive parts and the corresponding inserting cabins have no relative movement, so that abrasion is avoided, and the sealing effect is more long-lasting; the bounce of each elastic clamping sheet is force perpendicular to an inserting pin, so that the risk of pushing the inserting pin outwardly is avoided; and furthermore, the opening and closing of the weak-current control circuit are performed by adopting dual contacts, so that the safety is reinforced.

Description

technical field [0001] The invention relates to a waterproof socket. Background technique [0002] At present, most sockets on the market use safety door technology, and the protective structure can block the socket inside, but this kind of socket has no waterproof function, and water or water vapor can enter the gap between the protective door and the socket cover, causing a short circuit. Most of the existing waterproof sockets adopt the method of pressing the slider, and the circuit is connected by pressing the lever structure or the contact point through the slider, and the slider usually needs elastic parts such as springs to rebound and reset. The slider of this kind of waterproof socket needs to slide repeatedly, and the seal at the sliding seal is easy to wear, which affects the sealing performance, and the plug may be rebounded by the spring after insertion, resulting in instantaneous power failure, which cannot guarantee stability and may damage the plug. Electric...
