Abstract

The utility model relates to a power supply plugboard possessing the timing protection function. The power supply plugboard is provided with a housing having a socket. The socket includes regular sockets and timing protection sockets. The output terminal D of the regular sockets is connected with the power input terminal M. The output terminal C of the regular sockets is connected with the output terminal A of the timing protection sockets. The output terminal A of the timing protection sockets is connected with the power input terminal A via a short circuit breaker. The output terminal B of the timing protection sockets is connected with the power input terminal M via a timing breaker. The regular sockets and the timing protection sockets include n sockets which are same in structure. A socket resistor and an indicating lamp are connected in series between the two output terminals of each socket, and the indicating lamps are connected with the output terminal A of the timing protection sockets via switches. A main switch and a heating protection resistor are connected in series between the power input terminal M and the output terminal D of the regular sockets. The power supply plugboard possessing the timing protection function can preset the power using time, thus reducing the power consumption and prolonging the service lifetime of an electrical appliance. At the same time, the power supply plugboard possessing the timing protection function can rapidly detect the short circuit fault of the electrical appliance, is easy to use, and is safe, economical and practical.

Summary of the invention

The technical problems to be solved in the utility model is: provide a kind of simple in structure, safe and reliable and economical and practical a kind of band encryption electric socket, to overcome the existing deficiency of above-mentioned prior art.

For solving above-mentioned technical problem; the technical scheme that the utility model is taked is: a kind of band encryption electric socket; comprise the shell that is provided with socket; described socket comprises conventional socket and encryption socket; the output D of conventional socket is connected with power input M; the output C of conventional socket is connected with the output terminals A of encryption socket; the output terminals A of encryption socket is connected with power input N by the short circuit circuit breaker, and the output B of encryption socket is connected with power input M by electrotimer.

Its further technical scheme is: described conventional socket comprises the identical socket of n group structure with the encryption socket, that is: be connected in series jack resistance and indicator light between two outputs of socket, indicator light is connected with the output terminals A of encryption socket or the output C of conventional socket by switch; The numerical value of said n is the arbitrary integer between 1～10.

Its further technical scheme be: be serially connected with master switch between the output D of described power input M and conventional socket.

Be serially connected with the heating protective resistance between the output D of described master switch and conventional socket.

Owing to take above technical scheme, a kind of band encryption electric socket of the utility model has following beneficial effect:

Since the utility model a kind of with the encryption electric socket the encryption socket and power input between be serially connected with electrotimer; the user can preset the electricity consumption time as required; then can automatic shutoff circuit; but both electrical energy saving; reduce power consumption; prolong electrical equipment useful life, can improve Electrical Safety again, eliminate disaster hidden-trouble.

2. a kind of band encryption electric socket of the utility model is furnished with conventional socket and encryption socket simultaneously; can be for the user according to different needs; be serially connected with the short circuit circuit breaker between two kinds of sockets and the power input; there is short trouble in the electrical equipment that detects when maintenance; the short circuit circuit breaker can cut off the power supply in tripping; avoid causing new fault, the safety of protection electrical equipment and circuit.

The utility model a kind of with the encryption electric socket each group socket and power input between be connected with switch and indicator light; can show intuitively whether this socket switches on; the user can be switched on or switched off the power supply of socket as required, need not to pull out plug, and is practical and convenient.

Be further described below in conjunction with a kind of technical characterictic with the encryption electric socket of drawings and Examples to the utility model.
