Abstract
The utility model relates to a power source socket, especially a power cut self locking socket, which solves the problem of prior power source socket being energy waste when power is back, influencing service life of appliances and easy for danger. The socket comprises a socket shell with jacks, the socket shell is sealed with a relay J, the relay J and a switch S2 arranged on the socket shell are connected in series between the two power input leads, the switch S2 is connected in parallel with a normal open point J1 of the relay J, the jacks of the socket are connected in parallel with two ends of the relay J. The utility model is simple in structure, reasonable, of low manufacture cost and good employment effect, which is of good retailing prospect.
Description
Technical field
The utility model relates to a kind of supply socket, specifically is a kind of power failure positive locking female connector.
Background technology
The main effect of supply socket is to provide supply hub for a plurality of electrical appliances, present supply socket is for security consideration, the general whether charged control switch of control supply socket that on its incoming line, is serially connected with, but the setting of this control switch still can't be avoided: if unexpected situation about having a power failure, if the user forgets turn off electrical appliance or forget plug is taken off or control switch do not disconnected from socket, behind incoming call, be easy to generate following consequence: 1, waste electric energy; 2, reduce the useful life of electrical appliance; 3, cause danger easily, can cause fire when serious.
Summary of the invention
The problem that has the waste electric energy when the utility model is sent a telegram here after power failure once more in order to solve the existing power supply socket, influences electrical appliance useful life, easily causes danger provides a kind of power failure positive locking female connector.
The utility model is to adopt following technical scheme to realize: a kind of power failure positive locking female connector, comprise the Socket casing that is provided with jack, be packaged with relay J in the Socket casing, relay J and the switch S 2 that is arranged on the Socket casing are serially connected with between two power input lines, switch S 2 is in parallel with the normally opened contact J1 of relay J, and the jack on the socket is in parallel with the two ends of relay J.During use, Closing Switch S2, relay J gets electric, and the normally opened contact J1 closure of relay J forms self-locking, cut-off switch S2 then; When having a power failure, the relay J dead electricity, its normally opened contact J1 disconnects; Behind incoming call, switch S 2 is in off-state, the relay J dead electricity, and its normally opened contact J1 disconnects, and whole socket is in electroless state, as the need electricity consumption, first Closing Switch S2, and then with its disconnection.Compared with prior art, the utility model is provided with switch S 2 and is controlled by switch S 2 in socket relay J, make socket when electricity consumption, the self-locking of relay J and its normally opened contact J1 realizes normal power supply, when having a power failure the back incoming call, must just can carry out normal power supply by the self-locking of switch S 2 realization relay J and its normally opened contact J1.Existing security hidden trouble when fundamentally solving the use of existing power supply socket.
The utility model is simple and reasonable for structure, and production cost is low, and serviceability is good, has good prospect for sales.

Embodiment
A kind of power failure positive locking female connector, comprise the Socket casing that is provided with jack, be packaged with relay J in the Socket casing, relay J and the switch S 2 that is arranged on the Socket casing are serially connected with between two power input lines, switch S 2 is in parallel with the normally opened contact J1 of relay J, and the jack on the socket is in parallel with the two ends of relay J.
During concrete enforcement, the power input line-live wire in the socket is serially connected with switch S 1, and the series arm two ends of switch S 2 and relay J are parallel with the series arm of resistance R and LED, and the LED two ends are parallel with diode IN4004.Being provided with in the setting of switch S 1 and LED and the existing power supply socket is consistent.
Claims (1)
1. power failure positive locking female connector, comprise the Socket casing that is provided with jack, it is characterized in that being packaged with in the Socket casing relay J, relay J and the switch S 2 that is arranged on the Socket casing are serially connected with between two power input lines, switch S 2 is in parallel with the normally opened contact J1 of relay J, and the jack on the socket is in parallel with the two ends of relay J.
