Brief description of the drawings

Fig. 1 is the structural representation of safety socket of the present utility model.

Embodiment

Below by drawings and Examples, the technical solution of the utility model is described in further detail.

Supply socket of the present utility model is the safety socket with measuring ability, efficiently solves because of improper use and the installation and maintenance problem causing lack of standardization.

Fig. 1 is the structural representation of safety socket of the present utility model, and as shown in the figure, this safety socket comprises: jack body 10, power supply linkage unit 20 and detecting unit 30.

Jack body 10 is divided into the two-layer of isolation up and down, and upper strata comprises the jack 11 of mutual isolation, the annular protrusion 12 of sealing, also comprises the touching switch 21 in power supply linkage unit 20.Lower floor comprises delay controller 22, power supply coupling cock 23, detecting unit 30 and the plug 13 of power supply linkage unit 20.Due to upper-lower seal isolation, even if conductive materials enters in the jack 11 on upper strata, can not enter other circuit parts of lower floor yet.Therefore, adopt and isolate up and down jack body 10, safety socket is had to protective effect.

Jack body 10 inside have several jacks 11 of mutually isolating, as shown in Figure 1, the present embodiment is the safety socket of an external plug of can pegging graft, therefore there are 3 jacks 11 of isolation mutually, 3 jacks 11 are isolated mutually, in the time that conductive materials enters a jack, other jacks can be unaffected.The surrounding of jack 11 has the first closed ring projection 12, the first closed ring projection 12 employing elasticity not water wetted material are made, in the time that external plug is inserted the jack 11 of safety socket, the first closed ring projection 12 contacts with the contact-making surface elastic packing of external plug, therefore conductive materials to external world, as water, wet goods, play certain buffer action.

Power supply linkage unit 20 comprises touching switch 21, delay controller 22, power supply coupling cock 23.Touching switch 21 is positioned at the bottom on the upper strata of jack body 10, in the time that external plug is inserted jack 11, is electrically connected, and sends folding signal with touching switch 21.Delay controller 22 is positioned at the lower floor of jack body 10, and delay controller 22 receives the folding signal sending from touching switch 21.Power supply coupling cock 23 is positioned at the lower floor of jack body 10, is electrically connected with delay controller 22, and delay controller 22 is controlled the connection of power supply coupling cock 23 according to the folding signal receiving.Control the connection of safety socket by power supply linkage unit 20, will can not produce electric spark at external plug splicing position, electric spark will be transferred to power supply coupling cock 23 places of safety power supply inside.Touching switch 21 adopts the thin film switch with water-proof function, has improved the water-proof function of safety socket.Power supply coupling cock 23 is normal open switch, has improved the security performance of safety socket.

Detecting unit 30 is positioned at the lower floor of jack body, comprises state detection module, processing module and display module.State detection module detects the connection status of ground wire, zero line and live wire, determines connection status by the electric potential relation of measuring between three, for example, detects the whether normal ground connection of ground wire, and whether the connection of zero live wire is correct etc.Processing module is electrically connected with state detection module, judges its connection state according to three's electric potential relation, and draws state information.Display module is electrically connected with processing module, and the state information obtaining according to processing shows connection state in real time, and the form that display module can pass through sound, indicator light or data shows connection state.The connection state of demonstration ground wire, zero line and live wire that can be accurately real-time by detecting unit 30, has therefore got rid of the potential safety hazard of bringing because of installation and maintenance and apparatus failure.

On the contact-making surface of the plug 13 of safety socket, there is the second closed ring projection 14, in the time that plug 13 inserts external receptacle, contact with the contact-making surface elastic packing of external receptacle.Prevent entering of extraneous conductive materials.

In the process of use safety socket, in the time that external plug is inserted jack 11, be electrically connected with touching switch 21, and send folding signal, delay controller 22 receives the folding signal sending from touching switch 21, and control the connection of power supply coupling cock 23, and in the time that power supply coupling cock 23 is communicated with, the work of safety socket normal power-up.

Safety socket of the present utility model is divided into the two-layer of isolation up and down and each jack is kept apart, and has avoided damaging whole socket because jack enters conductive materials; Employing has the power supply linkage unit of time-lag action, has solved plug splicing position and has produced the problem of electric spark, and touched the problem of easily getting an electric shock; Detecting unit has been added in supply socket, has solved the potential safety hazard of bringing because of problems such as installation and maintenance.

Above-described embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the foregoing is only embodiment of the present utility model; and be not used in limit protection range of the present utility model; all within spirit of the present utility model and principle, any amendment of making, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
