A kind of Surge Protector

Technical field

The utility model relates to surge protection technique field more particularly to a kind of Surge Protectors.

Background technique

Surge Protector is to provide the electronic device of security protection for various electronic equipments, instrument and meter, communication line, Its effect is that the instantaneous overvoltage for scurrying into power line, signal transmssion line is limited in the voltage range that equipment or system can bear It is interior, or powerful surge current aerial drainage is entered into ground, avoid equipment or system from being hit damage.

The trip assembley therefor of existing Surge Protector can only work and normal temperature environment, and the connection of the pad of trip assembley therefor is strong Degree is very low, and tripping easily occurs under high temperature environment by circuitry cuts, can not normally pass through lightning current, application environment ring Border is limited.

Utility model content

Technical problem to be solved in the utility model and the technical assignment of proposition are improved to the prior art, are provided A kind of Surge Protector, solve in current technology Surge Protector under high temperature environment can direct trip and cannot be normal through thunder The problem of electric current.

In order to solve the above technical problems, the technical solution of the utility model is:

A kind of Surge Protector, including shell, surge protector component and trip assembley therefor, the surge protector component and tripping Component connection, the two are arranged in shell and connect with the wiring pole for connecting with external circuit, the trip assembley therefor packet Include welding stage and be detached from elastic slice, groove has been opened up on the welding stage, be detached from the lug that groove is protruded into setting on elastic slice, groove with Solder is filled up between lug connect welding stage with elastic slice is detached from.Surge Protector described in the utility model utilizes recessed on welding stage Slot and the lug for protruding into groove increase welding stage and are detached from the contact area of elastic slice, and fill solder can effectively increase weldering in groove Doses increases welding stage and is detached from the bonding strength of elastic slice, thus under high temperature environment can be stable by lightning current, it avoids threading off Component direct trip leads to open circuit, it is ensured that Surge Protector reliably works in the high temperature environment.

Further, U-shaped through-hole is opened up on the disengaging elastic slice, the central region of U-shaped through-hole is formed by bending for stretching Enter the lug of groove, structural stability is good, reliably connect with welding stage so that being detached from elastic slice.

Further, the surge protector component includes concatenated varistor and gas-discharge tube, and varistor is low There is high impedance under Current Voltage, but its impedance persistently reduces with the rising of surge current and voltage, gas-discharge tube is Voltage switch type device has high impedance when without surge, Low ESR is mutated into when responding to surge voltage, and the two series connection makes With the leakage current of varistor can be cut off, to delay the aging of varistor, the working life of varistor is extended, The influence that varistor capacitance works to system is greatly reduced simultaneously.

Further, the varistor combined with trip assembley therefor constitute module one, module again and again with gas-discharge tube string It is associated between wiring pole, modularization is easily installed and safeguards replacement.

Further, there are two the module one settings, and symmetrical serial is at the two poles of the earth of gas-discharge tube.

Further, the module one includes module rack, and welding stage is connected on the electrode of varistor, varistor and de- The opening for exposing welding stage is opened up from the two sides that module rack is arranged in elastic slice, in the middle part of module rack, be detached from elastic slice opening with Welding stage is detached between elastic slice and varistor and is isolated by module rack by solder connection, and high reliablity of threading off works as varistor Gradually degrading causes temperature to gradually rise or when varistor encounters especially big overload current and passes through, the temperature of varistor Quickly raising is spent, is detached from the solder fusing between elastic slice and welding stage to which the two connection separates so that circuit disconnection, effective protection Equipment improves safety in utilization, reduces loss.

Further, the trip assembley therefor further includes pushing tow interrupter, and the pushing tow interrupter includes that arc extinguishing is sliding Plate and elastic component, the arc extinguishing slide plate, which is located at, to be detached between elastic slice and module rack, described elastic component one end and arc extinguishing slide plate The connection other end is connected in module rack, and arc extinguishing slide plate is resisted against the pad for being detached from elastic slice and welding stage under elastic component effect On, and the opening for covering module rack is moved to after being detached from elastic slice and separating with welding stage.It is excessive or failure causes to take off in electric current When from solder fusing between elastic slice and welding stage, arc extinguishing slide plate under the action of the elastic member slide and will open by the opening on box body Mouthful overlay masking, avoids the occurrence of gap, to effectively will be disengaged from elastic slice and separate with varistor and expand spacing distance to reach electric Purpose of the air bound from simultaneously arc extinguishing, effective protection equipment improve safety in utilization.

Further, remote signalling switch block is additionally provided in the module one, the remote signalling switch block includes remote signalling Pin one and in the raw when the remote signalling pin two that is separated with remote signalling pin one, be detached from elastic slice and welding stage be in connection status When, remote signalling pin two is pressed on remote signalling pin one by arc extinguishing slide plate, reliably can timely grasp the work shape of Surge Protector Condition, it is ensured that timely carry out maintenance processing.

Further, core frame is provided in the shell, on core frame, module one is symmetricly set on gas discharge pipe device The two sides of core frame, structure are simple, compact.

Further, it is provided with sliding rail on the core frame, matched sliding slot, the sliding peace of module one are set in module rack It is easy to loading and unloading on core frame.

Compared with prior art, the utility model advantage is:

The bonding strength of the trip assembley therefor of Surge Protector described in the utility model is high, under high temperature environment can be stable By lightning current, trip assembley therefor direct trip is avoided to lead to open circuit, can reliably worked in the high temperature environment, structure is simple, tight It gathers, occupancy is small in size, and stability in use is high, safety is good.
