Abstract
The utility model discloses an SPD downlead ground line connection structure. The structure comprises a base board, a PCB arranged above the base board and a ground line, wherein the PCB is connected with the base board by bolts, and a lower part of the base board is provided with a copper bar by which the base board is connected with the ground line. The copper bar is fixedly connected with the ground line by bolts, the thickness of the base board is 1.5-3 mm, and the surface of the base board is provided with a metal coating. An SPD lightning protection module is arranged on the PCB, and the SPD lightning protection module is internally provided with a hot melting and current fusing device. With the SPD downlead ground line connection structure, the cross section of the downlead ground line is maximized, and the metal coating is used for effectively solving the skin effect of a lightning current; the copper bar is arranged at the lower end of the base board and closely contacted with the base board for mounting and fastening the downlead, such that the voltage drop from bolts at the rear end of the SPD lightning protection module to the grounding copper bar is reduced to the minimum, thereby effectively solving the problem of excessive UP value caused by the voltage drop of the SPD connection line and the voltage drop of the box body.
Description
Technical field
The utility model relates to a kind of ground line configuration, particularly relate under a kind of SPD Wiring connecting structure.
Background technology
The tradition lightning protection box adopts module to be installed in the case, passes transducer again and is connected on the copper bar, draws ground wire down from copper bar during construction and installation.Because connected node is many, there are node-resistance and inductance value problem too in following ground wire bending and distance, cause the UP value high.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide under a kind of SPD Wiring connecting structure, maximum is accomplished in cross section, following ground, and skin effect and voltage drop are well solved.
In order to achieve the above object, the technical solution adopted in the utility model is: under a kind of SPD Wiring connecting structure, comprise base plate, be arranged at pcb board and the earth connection of base plate top, described pcb board is connected with base plate by screw column, bottom at base plate is provided with copper bar, and base plate is connected with earth connection by copper bar.
Further, described copper bar is fixedlyed connected by screw column with earth connection.
Further, described base plate thickness is the 1.5-3 millimeter.
Further, described backplate surface adopts coating.
Further, described pcb board is provided with the SPD lightning-protection module.
Further, comprise hot melt and current fusing device in the described SPD lightning-protection module.
Compared with prior art, the beneficial effects of the utility model are: maximization is accomplished in the cross section down, skin effect and voltage drop are well solved, add a copper bar is used for installing and fastening downlead in the lower end of base plate, what become from SPD lightning-protection module rear end screw column to the pressure drop of ground connection copper bar end is minimum,, preferably resolve connection SPD line problem of pressure drop.
Description of drawings
Fig. 1 is structural representation of the present utility model;
In the accompanying drawing: 1, base plate; 2, pcb board; 3, lightning-protection module; 4, screw column; 5, copper bar; 6, earth connection.
Embodiment
Be elaborated with reference to accompanying drawing below in conjunction with embodiment, in order to technical characterictic of the present utility model and advantage are carried out more deep annotation.
Structural representation of the present utility model as shown in Figure 1, under a kind of SPD Wiring connecting structure, comprise base plate 1, be arranged at pcb board 2 and the earth connection 6 of base plate 1 top, described pcb board 2 is connected with base plate 1 by screw column 4, be provided with copper bar 5 in the bottom of base plate 1, base plate 1 is connected with earth connection 6 by copper bar 5.
Further, described copper bar 5 and earth connection 6 are fixedlyed connected by screw column.
Further, described base plate 1 thickness is the 1.5-3 millimeter.
Further, described base plate 1 surface is provided with coating.
Further, described pcb board 2 is provided with SPD lightning-protection module 3.
Further, comprise hot melt and current fusing device in the described SPD lightning-protection module 3.
Pressure-sensitive module of the present invention adopts protected mode over the ground, lightning surge arrives screw column 4 by SPD lightning-protection module 3, screw column 4 directly connects base plate 1(base plate 1 to be worked to support pcb board 2 and is fixed in the casing, general lightning protection box all uses), base plate 1 adopts the base plate of thickness 2-3 millimeter to add coating; Make that the cross section maximizes down, skin effect and line pressure drop are well solved, add a copper bar 5 in the lower end of base plate 1 and be used for installing and fastening earth connection 6, what become from SPD lightning-protection module 3 rear end screw columns 4 to the 5 end pressure drops of ground connection copper bar is minimum, preferably resolves to connect SPD line problem of pressure drop.
Above content be in conjunction with concrete optimal way to further describing that the utility model is done, should not assert that concrete enforcement of the present utility model is confined to above explanation.For those skilled in the art, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, within the protection range that the claim that all should be considered as being submitted to by the utility model is determined.
