Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below in conjunction with drawings and Examples pair
The segmentation safety socket and plug of the present invention is further elaborated.It should be appreciated that specific embodiment described herein
It is only used for explaining the present invention, is not intended to limit the present invention.
Segmentation safety socket as shown in Figure 1, including shell 1, it is provided with the shell 1 for being inserted with electric appliance load
At least two jacks and meet electric section 2, in addition to wiring section 3 and shock-isolator 4, institute correspondingly with the jack that head coordinates
State wiring section 3 to be arranged inside the shell 1, the wiring section 3 meets electric side of the section 2 away from the jack, institute positioned at described
State connect it is in parallel with the corresponding wiring section 3 after electric section 2 is connected with the corresponding shock-isolator 4, and described in plug insertion
Be can extend into after connecing electric section 2 in the corresponding wiring section 3, that is, plug insertion contacted with connecing electric section 2 when, connect electric section 2 and
Shock-isolator 4 is connected, and plug contacts with connecing electric section 2, and one of them connects electric section 2 because the series connection of shock-isolator 4 acts on, can
It is excessive to limit electric current, and has the function that, to its protection of plug, when plug continues into, plug contacts with wiring section 3, this
When, plug contacts with connecing electric section 2 and wiring section 3 simultaneously, and by the short circuit of shock-isolator 4, plug directly connects from wiring section 3 and circuit
It is logical so that electric appliance load normal work.
Wherein described shock-isolator 4 has larger resistance, can make the electric current in circuit will not breakdown potential perhaps electrical equipment
Load, after the shock-isolator 4 is shorted, electric appliance load can obtain normal electric current, not influence the work of electric appliance load.
When pulling the plug out of the socket, plug first disengages with wiring section 3, corresponding to connect the electric access of section 2 circuit, now shock-isolator 4
Also from short circuit Status Change for electricity condition, while produce limitation electric current effect, and because electric current reduce, can be effective
Suppress electric arc to produce, continue to pull the plug out of the socket, plug connects electric section 2 and disengaged with corresponding, completion withdrawal process, passes through shock-isolator 4
Access circuit, can effectively suppress the function of surge current.
Also include current supply line, one end of a current supply line described connects electric section 2 through the shell 1 with corresponding
Electrical connection, the wiring section 3 and it is corresponding it is described connect electric section 2 and be parallel to described in same root on current supply line, namely the He of wiring section 3
It is corresponding it is described connect electric section 2 and can obtain extraneous power supply at current supply line, namely wiring section 3 and corresponding described connect electric section
2 can be powered for electric appliance load.
The shock-isolator 4 is PTC resistor, because PTC resistor has positive temperature coefficient, after long-time is powered, due to
Temperature is raised, and its resistance can be raised and increased with temperature, and it is less and less to limit the electric current that it passes through, but electric current reduces, its PTC
On temperature also will not infinitely increase, but reach a balance, and then protective loop can be played a part of.
Electric section 2 is connect described in all and the wiring section 3 is made of electrically conductive material, namely can be that electric appliance load supplies
Electricity.
The wiring section 3 with it is corresponding it is described connect electric section 2 and be in same plane, namely the wiring section 3 with it is corresponding
It is described to connect electric section 2 and be inserted by same strip plug, and then the most of plug of in the market can be adapted to.
The quantity for connecing electric section 2 is two, and including live wire section and nil segment, the shock-isolator 4 and the live wire
End series connection, and the wiring section 3 is in parallel with the live wire section, namely socket now is two-phase socket, shock-isolator 4 and socket
On live wire connected, being capable of effective control electric current.

Zero line is connected, and the wiring section 3 is in parallel with the live wire section, with two-pin plug similarly.
Electric section 2 and the wiring section 3 of connecing includes two power connecting sheets 5, and is provided between two power connecting sheets 5
For the spacing of plug insertion, plug inserts from the spacing between two power connecting sheets 5.
The power connecting sheet 5 is arcuate structure, and the spacing for being smaller than both ends at two middle parts of power connecting sheets 5, namely two
Spacing of the power connecting sheet 5 between is bent, between plug effectively is clamped in into two power connecting sheets 5,
Reach fixed purpose.
A kind of plug for above-mentioned segmentation safety socket as shown in Figure 2, including body and it is arranged at the body
On at least two electric conductors for being inserted into the jack, an electric conductor can extend into the jack and connect with described
Line segment 3 and it is corresponding it is described connect electric section 2 while contact, namely will connect electric section 2 using the length of electric conductor and shock-isolator 4 is short
Road.
First step is provided with the wiring section 3 and the corresponding electric conductor for connecing electric section 2 while contacting
And second step, there is spacing between the first step and the second step, and in the fully-inserted socket of plug, it is described
First step coordinates with the wiring section 3, and the second step connects electric section 2 and coordinated with corresponding, meanwhile, connecing electric section 2 and connecing
Line segment 3 includes two power connecting sheets 5, and when two power connecting sheets 5 are arcuate structure, the meeting when first step insertion connects electric section 2
There is certain resistance, similarly, when first step inserts wiring section 3, second step, which is also inserted into, connects electric section 2, resistance increase, plays
Delay the effect of insertion, meanwhile, when pulling the plug out of the socket, first step when connecing electric section 2 by can also produce resistance, aforesaid operations
It can utilize shock-isolator 4 to reduce electric current, reduce electric arc.
Embodiment described above only expresses the several embodiments of the present invention, and its description is more specific and detailed, but simultaneously
Therefore the limitation to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that for one of ordinary skill in the art
