Abstract
The utility model relates to a lightning protection device, in particular to a surge protection device, mainly aiming at solving the technical problems that when a plurality of existing surge protection devices in the prior art are needed for use, the surge protection devices are connected together in series by screws and the like, the manufacture is more inconvenient, and the like. The surge protection device comprises a base (1), and is characterized in that the middle part of the base (1) is provided with a plug-in cavity; two sides of the plug-in cavity are provided with sliding grooves; the plug-in cavity is internally provided with a surge protection module (2) which is plugged into the plug-in cavity by the sliding grooves; bases arranged at the two sides of the plug-in cavity are respectively connected with an input terminal (3) and an output terminal (4) which are communicated with the surge protection module by a connecting plate (5); and the bottom of the base is provided with a nick (6) connected with a guide rail.
Description
Technical field
The utility model relates to a kind of lightning protection equipment, especially relates to a kind of to the isostructural improvement of surge protector.
Background technology
Surge is a kind of of short duration electric current, the voltage fluctuation that occurs in the circuit.It is from two aspects: external surge and inner surge.The topmost source of external surge is a thunder and lightning.Charge potential between thundercloud layer and ground is up to hundred ten thousand volts, when thunderbolt takes place,, returns cloud layer through equipment and the earth that it punctured, thereby finished the path of thunder and lightning by lightning discharge with the electric current of hundreds of dried peaces.Near the power line if thunder and lightning has hit, the part electric current will enter building along the line, and the electric current that this strand is huge will directly seal in power consumption equipment, and the insulation that destroys electric equipment causes the damage of electric equipment.Chinese patent discloses a kind of surge protector (Granted publication number: CN 2874884Y), it comprises module and base, the middle part that module is included in housing is provided with the thermistor valve block, the direct connection electrode of one end of thermistor valve block, connection electrode after the other end is connected with thermal cut-off and overcurrent protector, status display panel one end is that the low temperature weld tabs is connected with thermal cut-off, be connected by extension spring between the other end and the shell, module further comprises a temperature-sensitive device, temperature-sensitive device is arranged on the thermistor valve block, and housing is stretched out by output in the two poles of the earth of temperature-sensitive device; Base comprises the access terminal and the lead-out terminal of electrical connection, inserts the temperature-sensitive device output of the corresponding described module of terminal; Base comprises the passage and the connector that is connected with the electrode of described module of electrical connection by recess and base combination in the pedestal, temperature-sensitive device is a thermistor, and the output of temperature-sensitive device is the contact pin structure, and the thermal cut device is the low temperature weld tabs.When but this surge protector needs a plurality of uses, need it be serially connected, make inconvenience with screw etc.
The utility model content
The utility model technical issues that need to address provide a kind of surge protector, and it mainly is when solving the existing in prior technology surge protector and needing a plurality of uses, need it be serially connected with screw etc., and manufacturing is than the technical problem of inconvenience etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Surge protector of the present utility model; comprise pedestal; it is characterized in that described pedestal middle part has the grafting cavity; the both sides of grafting cavity are provided with chute; be provided with the surge protection module in the grafting cavity, the surge protection module is plugged in the grafting cavity by chute, is connected with input terminal, outlet terminal respectively on the pedestal of grafting cavity both sides; input terminal, outlet terminal are communicated with the surge protection module by gusset piece, and the bottom of pedestal is provided with the breach that can connect guide rail.A plurality of surge protectors are arranged in together and can be fixed on the guide rail of protector shelf by breach, the protector shelf can be fit in the equipment.The shape of breach and the shape of guide rail adapt.The surge protection module is the general module that circuit can be cut off the effect of playing protection electrical equipment when being struck by lightning.The both sides of grafting cavity inside all are provided with chute, make the surge protection module can successfully insert the grafting cavity inside.The width of the width of grafting cavity and surge protection module adapts.The bottom of grafting cavity can be provided with plug and connect gusset piece, and when the surge protection module was inserted like this, the plug of grafting cavity bottom can be communicated with the metalwork of surge protection module, makes whole circuit connect.Input terminal, outlet terminal can be screws, after the joint of circuit contacts input terminal, outlet terminal, by screwing screw, can be fixed.
As preferably, described breach one end is provided with clamp, and clamp is connected base bottom by spring.After the breach of base bottom was buckled on the guide rail, by the effect of spring, clamp can withstand guide rail one side automatically, makes pedestal to be fixed on the guide rail better.
Therefore, the utlity model has surge protector in use, can be as required, the surge protector of requirement is connected on the guide rail, can arbitrarily remove and install, comparatively convenient, characteristics such as simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Parts, position and numbering among the figure: pedestal 1, surge protection module 2, input terminal 3, outlet terminal 4, gusset piece 5, breach 6, clamp 7, spring 8.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the surge protector that this is routine, as Fig. 1, Fig. 2, a pedestal 1 is arranged, the middle part of pedestal has a grafting cavity, and the both sides of grafting cavity are provided with chute, and surge protection module 2 is plugged in the grafting cavity by chute.Be connected with input terminal 3, outlet terminal 4 on the pedestal of grafting cavity both sides respectively, input terminal 3, outlet terminal 4 are screw.Input terminal, outlet terminal are communicated with the surge protection module by gusset piece 5, and the bottom of pedestal is provided with the breach 6 that can connect guide rail, and an end of breach 6 is provided with the clamp 7 that can withstand on the guide rail, and clamp is connected pedestal 1 bottom by spring 8.
During use, the pedestal 1 of a plurality of surge protectors breach 6 by the bottom is connected on the guide rail, in the grafting cavity, inserts surge protection module 2, input terminal 3, outlet terminal 4 line attachments.When being struck by lightning, the circuit that the surge protection module can be excessive with electric current automatically cuts off, thereby has guaranteed the safety of electrical equipment.
