Description
Technical field
The present invention relates to a kind of electric supply installation, be specifically related to the supply socket of a kind of energy automatic test plug insert state.
Background technology
Supply socket is for powering to electrical appliance, generally, socket includes two groups of shell fragments, two groups of shell fragments are directly connected to phase line and the zero line of civil power respectively, socket leads to civil power length, when, after plug insertion socket, the civil power on socket i.e. flows into plug end load circuit, can also arrange three groups of shell fragments, the 3rd group of shell fragment is for ground connection.When circuit is short-circuited, only overload protection just can be carried out by air switch or electric fuse.If supply socket can be made to have plug detection function, the insert state of automatic test plug, then, on the one hand can more effectively ensure the Electrical Safety of socket, on the other hand, the function being also beneficial to charge electric power system controls.
In prior art, for realizing the detection of plug state, generally use the means such as switch or infrared distance measurement.
Such as, the Chinese invention patent of Publication No. CN101414719A discloses a kind of safety socket, including a supply socket and a detection switch, detection switch includes that a connecting key, an elastomeric element, an access terminal and pick out terminal, connecting key is placed on below fire line terminal and the zero terminal of supply socket, elastomeric element is used for supporting connecting key, and DC source is provided running voltage by detection switch to control unit and relay and forms a DC loop.Relay is connected on the fire line terminal of supply socket, and control unit determines adhesive and the disconnection of relay according to the connected state of detection switch.This structure uses the state of switch test plug, when plug inserts, connecting key is promoted to make access terminal and pick out terminal conducting, when plug is extracted, elastomeric element makes connecting key reset, disconnect and access terminal and pick out terminal, i.e. realize plug by mechanical movement and detect, there is the problems such as unreliable, wrong report.
The Chinese invention patent application of Publication No. CN103236613A discloses a kind of supply socket, find range in real time by being arranged on the range sensor at each group of jack, controlled whether corresponding chopper is operated, to ensure the power supply safety of supply socket by control module according to testing result again.This device arranges range sensor due to needs, and structure is complicated, cost is high, and meanwhile, range sensor needs to find range in real time, is constantly in duty, has both wasted the energy, also have impact on service life and dependability.
Accordingly, it is desirable to provide the supply socket with plug detection function of a kind of simple in construction, reliable operation, to adapt to the work requirements of various power control system.
Summary of the invention
The goal of the invention of the present invention is to provide a kind of supply socket with plug detection function, simply and reliably to realize the detection of plug.
To achieve the above object of the invention, the technical solution used in the present invention is: a kind of supply socket with plug detection function, the least one set jack including jack body, being arranged on jack body and the power supply circuits being arranged in jack body, at least a phase line jack and a zero line jack in each group of jack, described power supply circuits include phase line, zero line, testing circuit and control circuit；Corresponding each phase line jack is provided with a pair big shell fragment, described big shell fragment is connected with phase line, and corresponding each zero line jack is provided with the little shell fragment of two couple being disposed adjacent, and the little shell fragment of one pair of which is connected with zero line, little shell fragment is connected by another with testing circuit, has clearance for insulation between the two corresponding shell fragments to little shell fragment；The output of testing circuit is connected to control circuit, and control circuit includes the relay controlling phase line break-make.
In technique scheme, two are arranged to little shell fragment by corresponding zero line jack, two to little bullet insulation between plates at ordinary times, testing circuit is separated with zero line, and when plug inserts, little shell fragment is turned on by two by plug, testing circuit constitutes complete loops and obtains electric, outputing signal to control circuit, control circuit controls relay adhesive, makes phase line turn on.Owing to former zero line shell fragment is divided into two parts, it is not necessary to arrange other action component or range sensor, therefore simple in construction.Meanwhile, testing circuit is connected with neutral side shell fragment and is not connected with phase line side shell fragment, thereby ensure that not charged at socket at ordinary times.
In technique scheme, testing circuit can use any one of the prior art circuit structure of energy output signal in the case of energising.The form of a kind of preferred simple in construction is, electric capacity that described testing circuit includes being connected in series between described little shell fragment and zero line, resistance, the luminous source of photoelectrical coupler, the light-receiving device output of photoelectrical coupler is connected to described control circuit.
Further technical scheme, in described testing circuit, is connected in series with the first diode with the luminous source of described photoelectrical coupler, with described resistance, the luminous source of photoelectrical coupler and the first diodes in parallel, is provided with the second oppositely arranged diode.By the setting of two diodes, photoelectrical coupler is played a protective role.
In technique scheme, described control circuit can use the circuit of any one prior art that can receive detection signal control relay adhesive.In order to coordinate the detection of various Fare Collection System to use, preferably technical scheme, described control circuit includes drive circuit, the relay that single-chip microcomputer is connected with the output port of single-chip microcomputer, the input circuit of described relay connects described drive circuit, and the output loop of described relay is connected in phase line.
Owing to technique scheme is used, the present invention compared with prior art has the advantage that
The present invention forms the little shell fragment of two couples of mutual insulating by being disconnected by zero line socket, it is achieved that the detection to plug insert state, realizes conducting between little shell fragment by plug due to two, therefore, need not arrange action component or sensor, simple in construction, ensure that the reliability of work simultaneously.
