Abstract
The utility model discloses a lightning protective socket, comprising a live wire (3), a zero wire (4) and a grounding wire (5), wherein a first pressure-sensitive resistor (RV1) is connected between the live wire (3) and the zero wire (4), a second pressure-sensitive resistor (RV2) is connected between the live wire (3) and the grounding wire (5), and a third pressure-sensitive resistor (RV3) is connected between the zero wire (4) and the grounding wire (5). The lightning protective socket is simple in structure and excellent in lightning protection effect.
Description
Technical field
The utility model relates to a kind of socket, relates to a kind of Thunder preventing socket or rather.
Background technology
Present developing rapidly along with science and technology; The electric equipment that people use is also more and more; And the internal structure of electric equipment is also more and more accurate, responsive, but because the existence in this strong external interference source of thunder and lightning, and electric equipment receives very big destruction because of thunderbolt through regular meeting.For avoiding socket to be struck by lightning, people have invented the Thunder preventing socket with lightning protection effect, but present Thunder preventing socket structure is poor than complicacy and lightning protection effect.
The utility model content
The technical problem that the utility model will solve is to provide a kind of simple in structure, the Thunder preventing socket that lightning protection effect is good.
The technical solution of the utility model is; A kind of Thunder preventing socket with following structure is provided; Comprise live wire, zero line and ground wire; Between live wire and zero line, be connected with first piezo-resistance, be connected with second piezo-resistance between live wire and the ground wire, be connected with the 3rd piezo-resistance between zero line and the ground wire.
The model of described first piezo-resistance, second piezo-resistance and the 3rd piezo-resistance is 14D471K.
After adopting above structure, the Thunder preventing socket of the utility model compared with prior art has the following advantages:
Because the Thunder preventing socket of the utility model is connected with first piezo-resistance between live wire and zero line; Be connected with second piezo-resistance between live wire and the ground wire; Be connected with the 3rd piezo-resistance between zero line and the ground wire, and the piezo-resistance resistance comparatively responsive to voltage that is a kind of resistance value, when promptly the voltage on being added in piezo-resistance is lower than its threshold values; Its resistance is very big, and the electric current that flows through it is minimum; But the voltage on being added in piezo-resistance reaches or when being higher than its threshold values, its resistance will diminish, and the electric current that flows through it will increase sharply.Therefore; When the Thunder preventing socket of the utility model is struck by lightning; Piezo-resistance in the socket can suppress to be struck by lightning and the abnormal overvoltage that causes; Protection socket and the electric equipment that links to each other with socket are avoided damage, and the Thunder preventing socket of the utility model is provided with first piezo-resistance, second piezo-resistance and the 3rd piezo-resistance, make lightning protection effect better.
Description of drawings
Fig. 1 is the partial circuit structural representation of the utility model Thunder preventing socket.
Fig. 2 is the internal structure sketch map of the utility model Thunder preventing socket.
Shown in the figure: 1, housing, 2, insertion hole groups, 3, live wire, 4, zero line, 5, ground wire, RV1, first piezo-resistance, RV2, second piezo-resistance, RV3, the 3rd piezo-resistance.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
See also Fig. 1 and shown in Figure 2, the Thunder preventing socket of the utility model comprises housing 1, insertion hole groups 2, live wire 3, zero line 4 and ground wire 5.Described insertion hole groups 2, live wire 3, zero line 4 and ground wire 5 are installed in the described housing 1.Between live wire 3 and zero line 4, be connected with the first piezo-resistance RV1, be connected with the second piezo-resistance RV2 between live wire 3 and the ground wire 5, be connected with the 3rd piezo-resistance RV3 between zero line 4 and the ground wire 5.In this specific embodiment, the model of the described first piezo-resistance RV1, the second piezo-resistance RV2 and the 3rd piezo-resistance RV3 is 14D471K.
Claims (2)
1. Thunder preventing socket; Comprise live wire (3), zero line (4) and ground wire (5); It is characterized in that: between live wire (3) and zero line (4), be connected with first piezo-resistance (RV1); Be connected with second piezo-resistance (RV2) between live wire (3) and the ground wire (5), be connected with the 3rd piezo-resistance (RV3) between zero line (4) and the ground wire (5).
