Embodiment
Below with reference to accompanying drawing, specific embodiments of the invention are described in detail.
Fig. 1 shows according to a kind of back panel wiring testing circuit schematic diagram with the single-phase socket of wiring measuring ability of the present invention.
As shown in Figure 1, the single-phase socket with detection connection function provided by the invention comprises phase line utmost point L, zero line utmost point N, ground wire utmost point E and testing circuit; Wherein, testing circuit comprises three light emitting diodes, three current-limiting resistances and a normally opened contact button 3.Particularly, light emitting diode 2 and current-limiting resistance 1 are connected between phase line utmost point L and zero line utmost point N successively; Current-limiting resistance 5 and light emitting diode 4 are connected between ground wire utmost point E and phase line utmost point L successively; Light emitting diode 8 and current-limiting resistance 6 are connected between zero line utmost point N and ground wire utmost point E successively.
From the circuit shown in Fig. 1, can find out, it is a loop that light emitting diode 2, current-limiting resistance 1, light emitting diode 8, current-limiting resistance 6, current-limiting resistance 5 and light emitting diode 4 are connected successively.And, between adjacent two light emitting diodes 4,2, be provided with a node A, between phase line utmost point L and node A, normally opened contact button 3 is set.Wherein, the optional position that node A can be between the light emitting diode between the light emitting diode between phase line utmost point L and ground wire utmost point E and phase line utmost point L and zero line utmost point N.
In order to detect wiring state and the circuit of makeing mistakes, light emitting diode 2 forwards are connected on phase line utmost point L to the circuit between zero line utmost point N, light emitting diode 4 forwards are connected on ground wire utmost point E to the circuit between phase line utmost point L, and light emitting diode 8 forwards are connected on zero line utmost point N to the circuit between ground wire utmost point E.
Due to zero line utmost point N be in generating plant, transformer station or transformer-supplied end ground connection, be the working earthing line utmost point.Zero line utmost point N does not form loop with transmission line of electricity, generally there is no electric current, and ground wire utmost point E is user side ground connection, can touch position is connected with the metal shell of electrical appliance or human body, makes casing and the earth equipotential, protects human body not get an electric shock.Phase line utmost point L is called again live wire, and N forms current supply circuit jointly with the zero line utmost point.The general voltage of live wire is family expenses 220V or industrial 36V under normal circumstances, and zero line utmost point N does not have voltage.Following situation is the judgement of making according to each line end electromotive force relation.
First, to all socket energisings that install;
Then, according to the luminous situation of the switch of normally opened contact button 3 and each light emitting diode, judge wiring state and occur wrong circuit.Specifically be divided into following situation:
When 1, socket energising and normally opened contact button 3 are not closed,
If light emitting diode 8 is shinny, there are two kinds of results.1. the phase line utmost point and the zero line utmost point connect instead; 2. ground wire is extremely charged.Now, normally opened contact button 3 can be pressed into closure state, if light emitting diode 2 is simultaneously shinny, this fault is that the phase line utmost point and the zero line utmost point connect instead, if still only have light emitting diode 8 shinny, this fault is that ground wire is extremely charged.
When 2, socket energising and normally opened contact button are closed,
If 1. light emitting diode 2,4 is simultaneously shinny, socket wiring is correct;
If 2. only light emitting diode 2 is shinny, lack ground wire utmost point E;
If 3. only light emitting diode 4 is shinny, lack zero line utmost point N;
If 4. light emitting diode 2,8 is simultaneously shinny, phase line utmost point L and zero line utmost point N connect instead;
If 5. light emitting diode 4,8 is simultaneously shinny, phase line utmost point L and ground wire utmost point E connect instead;
If 6. light emitting diode 2,4,8 is all not shinny, phase shortage line utmost point L.
Fig. 2 shows the panel appearance that has the single-phase socket of wiring measuring ability according to of the present invention.
As shown in Figure 2, light emitting diode 2,4,8 and normally opened contact button 3 are arranged according to the mode shown in Fig. 2 on socket panel 7 surfaces, user can be with reference to product operation instruction, according to the wiring error type of the on off operating mode judgement socket of light emitting diode 2,4,8, thereby carry out correct wiring adjustment.
Finally, after socket wiring is correct, user is pressed into normally open by contact button 3, cuts off socket back panel wiring testing circuit.
The single-phase socket that detects mutually connection function of the present invention is in powered situation, and the on off operating mode of three light emitting diodes by socket panel, can directly judge the wiring error type of socket, thereby carries out correct, rapid adjustment.It can face qualified installation person, also can face the crowd of domestic consumer, less demanding to operator quality.Also no longer need to be by special testing instruments such as plug type power detector, multimeter, electroprobes, have advantages of directly perceived, convenient, detection efficiency is high.
In addition, after socket wiring is detected, adjusted, user can be pressed into normally open by contact button 3, cuts off socket back panel wiring testing circuit, so that economize on electricity.
The object of this invention is that a kind of single-phase socket that detects connection function that has is provided to this area, substantially use under the prerequisite of function meeting single-phase socket, portion increases wiring testing circuit within it, its back panel wiring situation is embodied simply and intuitively, so that the socket of butted line mistake re-starts to adjust, process.
Above with reference to Fig. 1 and Fig. 2, the single-phase socket that has detection connection function according to of the present invention has been described in the mode of example.But, it will be appreciated by those skilled in the art that the single-phase socket that detects connection function that has proposing for the invention described above, can also on the basis that does not depart from content of the present invention, make various improvement.Therefore, protection scope of the present invention should be determined by the content of appending claims.
