Abstract
The invention relates to a lightningproof power supply connecter which comprises a conductive casing in which a group of connecting pieces are arranged; insulating medium is arranged between the connecting pieces and the conductive casing; first gravitrons are conductively connected between the connecting pieces and the conductive casing; and second gravitrons are conductively connected between live wire connecting pieces and zero wire connecting pieces. In the lightningproof power supply connector, because the gravitrons are conductively connected between the connecting pieces and the conductive casing and between the zero wire connecting pieces and the live wire connecting pieces used for connecting zero wires and live wires, when instantaneous induced overvoltage and overcurrent occur in a circuit in a lightning environment, the breakdown of the gravitrons happens to discharge the overvoltage and overcurrent to a cabinet or earth, thereby protecting equipment form being damaged by the overvoltage and overcurrent.
Description
Technical field
The present invention relates to a kind of power connector, particularly a kind of power connector with lightning protection function.
Background technology
Power connector is the critical component that connects power supply and power consumption equipment.Existing power connector does not all have the function of lightning protection.When thundery sky, can produce higher instantaneous induced voltage and electric current influencing in the lower connector of thunder and lightning.This induced voltage and electric current can be transferred in the equipment by power circuit, can cause bad influence to equipment, when serious entire equipment are burnt
Summary of the invention
The purpose of this invention is to provide a kind of lightning protection power connector, do not possess lightning protection function, under the environment of thunder and lightning is arranged, momentary excess current can occur in the power circuit, equipment is caused harmful effect in order to solve the existing power supply connector, even the problem of infringement equipment.
For achieving the above object, the present invention adopts following technical scheme: a kind of lightning protection power connector, comprise conductive shell, be provided with a set of contact part in the conductive shell, be provided with dielectric between described contact and the conductive shell, between described each contact and the conductive shell all conduction be connected with first gas discharge tube.
Described contact comprises live wire contact and zero line contact, and conduction is connected with second gas discharge tube between described live wire contact and the zero line contact.
Be relatively set with ground connection printed board and wiring printed board in the described conductive shell, described ground connection printed board is connected with the conductive shell conduction, described each contact all is connected with wiring printed board conduction, terminals of described first gas discharge tube and ground connection printed board conduction connect another terminals and are connected with corresponding contact conduction by the wiring printed board, and terminals of described second gas discharge tube conduct electricity the printed board of passing through to connect up of another terminals of connection by wiring printed board and corresponding live wire contact and conduct electricity with corresponding zero line contact and be connected.
Described first, second gas discharge tube is all between ground connection printed board and wiring printed board.
Radially be pressed with the ground connection spring between described ground connection printed board and the conductive shell, this ground connection spring is connected with the conductive shell conduction with the ground connection printed board respectively.
Clamped insulating case between described ground connection printed board and the wiring printed board, described first, second gas discharge tube all is threaded onto in this insulating case.
The middle part in the described conductive shell outside is along being circumferentially with mounting panel, and this mounting panel is provided with the conduction rubber cushion near a side of connector terminals.
Lightning protection connector of the present invention, all conduction is connected with first gas discharge tube between contact and conductive shell.When in the thunder and lightning environment, when occurring instantaneous induction overvoltage and overcurrent on the circuit, gas discharge tube is breakdown and with overvoltage and the overcurrent cabinet or on the ground big of releasing, and has protected equipment, makes it avoid the damage of overvoltage and overcurrent.
In addition, conduction is set between zero line contact that is used to connect zero line and live wire and live wire contact is connected with second gas discharge tube, overvoltage and overcurrent that second gas discharge tube is used for releasing that lightning induction acts on zero, produce on the live wire road.
Simultaneously, clamped insulating case between ground connection printed board and the wiring printed board, this insulator had both increased the intensity of ground connection printed board with the wiring printed board, had improved the insulation property between ground connection printed board and wiring printed board and each contact again.
