Description

Electric shock terminal board

technical field

The utility model relates to an electric shock-proof wiring board.

Background technique

With the increase of electrical equipment, the utilization rate of terminal boards is also getting higher and higher. Although some high-tech wiring boards have protective measures, people generally use some cheap common wiring boards, and now the cheap common wiring boards are directly composed of plugs and sockets. The conductive contacts in the board can be energized if they are connected, and if the insertion is not tight, it will easily lead to electric shock hazard. In addition, when the terminal board is not in use, sometimes forget to turn off the main switch of the terminal board, and it is very easy for children to insert their fingers through other conductive objects into the socket and get an electric shock.

Contents of the invention

In order to overcome the disadvantages of unsafe and easily electric shock in the existing wiring board, the utility model provides a cheap and safe electric shock-proof wiring board.

The technical scheme that the utility model adopts is:

The anti-shock terminal board includes a casing, a plurality of sockets and flippable safety covers on the casing as many as the sockets, and is characterized in that: the casing and the safety cover are connected by a rotating shaft, and the rotating shaft is provided There is a plastic arm, and the arm head of the plastic arm is fixed with a horizontal conductive contact piece; the first switch, the indicator light and the second switch with the same number as the jack are arranged in the said shell, and the second switch is provided with two A "card" device that can hold the conductive contact piece; in the middle of the safety cover, there is a strip-shaped gap that connects the plug wire with the outside world, and the side of the strip-shaped gap is in contact with the shell and the corresponding part of the shell. The positions are all equipped with permanent magnets.

Before the utility model is used, the safety cover is closed and the first switch is disconnected; when in use, the first switch is opened, the indicator light is on, and the safety cover on one of the required jacks is opened, and the corresponding second switch is disconnected at this time, so It can effectively prevent electric shock caused by accidentally inserting fingers or conductive objects into the jack, then insert the plug claws into the jack, and cover the safety cover. This is the corresponding permanent magnet of the safety cover and the wiring board shell. The safety cover firmly covers the plug. Since there is a strip slit in the middle of the safety cover, the wire connected to the plug can be effectively connected to the outside when the cover is covered. When the safety cap is covered, the "card" device on the second switch will be activated. Clamp the horizontal conductive contact connected to the plastic arm head, close the corresponding switch, and then it can be powered on and used. In addition, due to the protection of the safety cover, it can effectively prevent the danger of electric shock due to unintentional part of the plug being pulled out. Setting the second switch on the live wire can prevent the risk of electric shock caused by accidental fingers or conductive objects touching the socket when the safety cover is opened.

The beneficial effects of the utility model are embodied in: cheap and safe, and good effect of preventing electric shock.

Detailed ways

Referring to Fig. 1 and Fig. 2, the anti-shock wiring board includes a housing 10, a plurality of jacks and a safety cover 1 that can be turned over on the housing 10 as many as the jacks, and is characterized in that the housing 10 and the safety cover 1 is connected by a rotating shaft 4, and the rotating shaft 4 is provided with a plastic arm 5, and the arm head of the plastic arm 5 is fixed with a horizontal conductive contact piece 6; the housing 10 is provided with a first switch 8, an indicator light 9 and The second switch with the same number as the jack, the second switch is provided with two "card" devices 7 that can clamp the conductive contact piece 6; the middle of the safety cover 1 is provided with a plug wire that can connect the plug wire to the outside world The strip-shaped gap 3, the place where the side of the strip-shaped gap 3 is in contact with the shell 10 and the position of the corresponding part of the shell 10 are equipped with permanent magnets 2.

Before the utility model is used, the safety cover is closed and the first switch is disconnected; when in use, the first switch is turned on, the indicator light is on, and the safety cover on one of the required jacks is opened, and the corresponding second switch is disconnected at this time, so It can effectively prevent electric shock due to accidentally inserting fingers or conductive objects into the jack, then insert the plug claws into the jack, and cover the safety cover. At this time, the safety cover and the corresponding permanent magnet on the wiring board shell will work. The safety cover firmly covers the plug. Since there is a strip slit in the middle of the safety cover, the wire connected to the plug can be effectively connected to the outside when the cover is covered. When the safety cap is covered, the "card" device on the second switch will be activated. Clamp the horizontal conductive contact piece connected with the plastic arm head, close the corresponding switch, and then it can be energized and used. In addition, because of the protection of the safety cover, it can effectively prevent the danger of electric shock due to unintentional part of the plug being pulled out. Setting the second switch on the live wire can prevent the risk of electric shock caused by accidental fingers or conductive objects touching the socket when the safety cover is opened.
