Abstract
The utility model relates to a safety power supply plug wire plate. The utility model is composed of a bottom board (3), a cover plate (5), a power switch, a pair of conductive metal plates and two power wiring end heads, wherein the power switch is two metallic conductive contact pieces and a double disconnecting power switch which can conduct simultaneously closure and disconnection actions, and each power wiring end head and a corresponding metallic conductive contact piece form a double-path electric conductive and disconnecting switching structure by the power switch. The utility model solves the problem that the existing plug wire plate has low power utilization safety and generates easily electric shock accidents caused by touching a single wire. The utility model is used for providing power supply for loads.
Description
The utility model relates to a kind of low-voltage power circuit turn-on and turn-off control assembly, particularly a kind of safety power supply wiring board.
At present, a kind of belt switch power supply wiring board that people generally use, mainly form by cover plate, mains switch, two conductive metal sheets and a power supply wiring termination of base plate, band patchhole, mains switch is arranged between power supply wiring termination and the conductive metal sheet, carries out single line and conducts switching with off state.When mains switch and power supply wiring termination and live wire joined, mains switch closes had no progeny, and then the circuit of wiring board and back thereof is not charged.When if mains switch and power supply wiring termination and zero line join, mains switch closes has no progeny, then just with it the zero line of homonymy be cut off, and the single circuit of the opposite side that mains switch is not set still joins with live wire, load this moment does not quit work because of there being current circuit, be that power supply has broken outwardly, but it is still charged with the single circuit that live wire joins, if someone stands on the ground and is not intended to contact metal the end of a thread or plug metal film with hand, then can take place to get an electric shock or beaten phenomenon by electric shock, fail safe is relatively poor.
The purpose of this utility model is, provides a kind of electrical safety not influenced by the mains switch front end order of connection, and is safe and reliable, and accident of human electric shock's safety power supply wiring board can not take place.
In order to achieve the above object, the solution that the utility model is taked is, it is by base plate, the cover plate that is provided with plug insertion, mains switch, form with corresponding pair of conductive sheet metal of plug insertion and power supply wiring termination, described each conductive metal sheet is clamped on the base plate, and mains switch is arranged between described power supply wiring termination and the above-mentioned conductive metal sheet.Be characterized in that above-mentioned base plate is provided with two power supply wiring terminations.Mains switch is by carrying out closure simultaneously, disconnect the pair of metal conductive contact film of action and double break source switch that the manual control volume that is coupled as one with it constitutes, and promptly the double joint circuit conducts and the diverter switch that disconnects simultaneously.Above-mentioned two power supply wiring terminations are by corresponding metal conductive contact film on the mains switch, and the switching construction that the formation two-way conducts simultaneously and turn-offs between the corresponding above-mentioned conductive metal sheet.Promptly when mains switch is in off state, be off-state between two power supply wiring terminations of connection power firestreak and zero line and the corresponding conductive metal sheet, two-way turn-offs.When mains switch was in closure state, then two-way conducted, and load can be worked.
Above-mentioned mains switch can be selected slide switch, push-button switch or the rocker type switch that is provided with the pair of metal conductive contact film for use, certainly also can adopt soft-touch control with above-mentioned contact chip structure, remote control switch, audio-switch etc.In addition, can also be provided with the power supply display by cover plate, as neon big gun, light-emitting diode, low-power consumption lampet big gun etc.In mains switch two circuits in front, be connected to a protective tube respectively.Above-mentioned protective tube is provided with on base plate, the cover plate or in the space of both encirclements, position, syndeton are set for it and the position is set the power supply display and connecting line construction is known by those of ordinary skill, no longer describes in detail herein.
Because the utility model has adopted said structure, be that mains switch is the double break source switch, its change action can make two conductive metal sheets disconnect simultaneously with corresponding power firestreak, zero line two-way, and behind the power cutoff switch, any circuit of its back all can be not charged.Therefore, the utlity model has security reliability and not influenced by its power supply wiring termination and power firestreak, the zero line order of connection, accident of human electric shock's advantage can not take place.And it is simple in structure, and it is also comparatively convenient to use.
Below in conjunction with accompanying drawing utility model is further described.
