Description

Surge protector
Technical field
The invention belongs to the technical field of thunder resisting equipment, more particularly to surge protector.
Background technology
Lightning surge, LEMP and occurs surge in circuit during supply voltage abnormal sudden change, often (beyond normal The transient overvoltage of operating voltage), and cause electricity system and electrical equipment to damage, in order to avoid it is above-mentioned the occurrence of, respectively The surge protector of formula various kinds is come across in our daily life.The surge that surge protector is used on limiting circuitry, and let out Overcurrent on unwrapping wire road.
More than existing surge protector in the form of guide tracked installation, its bulky is brought to installation and maintenance Very big difficulty.
The content of the invention
It is an object of the invention to provide surge protector, it is intended to which solve existing surge protector causes peace because volume is big Fill problem difficult in maintenance.
In order to solve the above technical problems, the invention provides surge protector, including base and for by the base hood Outer cover firmly, the base be provided with piezo-resistance for overcurrent of releasing, slide set slide plate, for making the slide plate The pin shell fragment of positioning, the spring that elastic force is imposed to the slide plate, and contradicted by the slide plate and realize closure connection First alarm electrode and the second alarm electrode, the piezo-resistance have the first connection end and the second connection end, the pin bullet Piece one end is connected with first connection end by solder joint, and the other end is connected with first electrode piece, the second connection end connection There is second electrode piece.
The beneficial effect of the surge protector that the present invention is provided:
Protected using above-mentioned surge protector during operating circuit, when overvoltage or overcurrent occurred in operating circuit etc. During abnormal conditions, pin shell fragment will come off with the solder joint of the first connection end of piezo-resistance, and slide plate is because of the elastic force by spring Start to slide, and thoroughly cut off the electric connection of pin shell fragment and piezo-resistance, now, surge protector failure.Meanwhile, by In the slip of slide plate, slide plate will no longer contradict the second alarm electrode, the closure connection of the second alarm electrode and the first alarm electrode Disconnect, alarm circuit will export second and alert the signal that electrode and the first alarm electrode connection disconnect, can be by long-range prison Control equipment can monitor in time surge protector whether normal work, therefore, the surge protector response time is fast, reaches preferably Protection level, it is ensured that electrical equipment from overvoltage damage.Additionally, piezo-resistance, slide plate, pin shell fragment, spring, the first announcement Alert electrode, the second alarm electrode, first electrode piece and second electrode piece are integrated on base, and are covered by outer cover, its structure Simply, small volume, is easy to configuration in the onboard module of small size, and convenient for installation and maintenance, strong adaptability is particularly suited for space In compact equipment.

Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and It is not used in the restriction present invention.
As shown in Figures 1 to 3, it is the preferred embodiment for providing of the invention.
It should be noted that when element is referred to as " being fixed on " or " being arranged at " another element, it can be directly another On one element or it is connected on another element.When an element is known as " being connected to " another element, it can To be directly to another element or be indirectly connected on another element.
Also, it should be noted that the orientation term such as left and right, upper and lower in the present embodiment, be only each other relative concept or Normal operating condition with product is reference, and be should not be regarded as restrictive.
As shown in Figure 1 to Figure 3, the surge protector 10 that the present embodiment is provided, including base 11 and for base 11 to be covered Outer cover 12 firmly, base 11 be provided with piezo-resistance 13 for overcurrent of releasing, slide set slide plate 14, for making slide plate The pin shell fragment 15 of 14 positioning, the spring 16 that elastic force is imposed to slide plate 14, and contradicted by slide plate 14 and realize closure connection First alarm electrode 171 and second alarm electrode 172, piezo-resistance 13 have the first connection end 131 and the second connection end 132, the one end of pin shell fragment 15 is connected with the first connection end 131 by solder joint 18, and the other end is connected with first electrode piece 191, the Two connection ends 132 are connected with second electrode piece 192.Wherein, first electrode piece 191 and second electrode piece 192 are access works in parallel In making circuit;And the first alarm alarm electrode 172 of electrode 171 and second is connected in alarm circuit, so, far Range monitoring equipment can be monitored according to the alarm signal of alarm circuit surge protector 10 whether normal work.
As shown in Figure 1 to Figure 3, protected using above-mentioned surge protector 10 during operating circuit, when appearance in operating circuit Overvoltage or the abnormal conditions such as overcurrent when, pin shell fragment 15 will with the solder joint 18 of the first connection end 131 of piezo-resistance 13 Come off, slide plate 14 is slided because being started by the elastic force of spring 16, and has thoroughly cut off pin shell fragment 15 and piezo-resistance 13 It is electrically connected with, now, surge protector 10 fails.Simultaneously as the slip of slide plate 14, slide plate 14 will no longer contradict the second alarm Electrode 172, the closure connection of the second alarm alarm electrode 171 of electrode 172 and first disconnects, and alarm circuit will export second The signal that the alarm alarm connection of electrode 171 of electrode 172 and first disconnects, can in time monitor surge by remote supervisory and control(ling) equipment Protector 10 whether normal work, therefore, the leakage current and rate of change of the surge protector 10 are small, and residual voltage is low, and through-current capacity is big, ring It is fast between seasonable, product is reached preferable protection level, it is ensured that electrical equipment is damaged from overvoltage.Additionally, piezo-resistance 13, Slide plate 14, pin shell fragment 15, the alarm alarm of electrode 171, second of spring 16, first electrode 172, first electrode piece 191 and second Electrode slice 192 is integrated on base 11, and is covered by outer cover 12, its simple structure, small volume, is easy to configuration in small size Convenient for installation and maintenance in onboard module, strong adaptability is particularly suited in the equipment of spaces compact.
It should be noted that under normal circumstances, the current value by surge protector 10 is very small, works as operating circuit When the lightning surge or surge current of appearance, due to the nonlinear characteristic of piezo-resistance 13, piezo-resistance 13 is can be transferred through Overvoltage and overcurrent are released.
You need to add is that, pin shell fragment 15 have elasticity, its with piezo-resistance 13 by being welded to connect when, pin shell fragment 15 are in compressive state.
