Fig. 1 ~ Fig. 3 shows a kind of structure of existing conductive connection plates.Like Fig. 1 ~ shown in Figure 3, binding 101 with draw the tube connector 102 of reaching the standard grade and be connected with joint form, both contact positions are the line contact, the both sides of online contact are fixed through electric welding then.Its shortcoming is: (one) binding 101 is less with the contact area of drawing the tube connector 102 of reaching the standard grade, and functional reliability is poor, and is unfavorable for passing through rapidly of big electric current (like thunder and lightning); (2) both sides of online contact only, weld zone 103 draw when welding that end usually seldom is in quadrature position about reach the standard grade tube connector 102 and binding 101, become crooked connection status, and the percentage of A-class goods reduces; (3) two bolts hole on the binding 101 all are circular holes, and are difficult to the hole when being connected with electric power line pole tower, and possible one of them hole is to last, and another hole has increased the difficulty of construction but to not going up.
The utility model content
To the above-mentioned shortcomings and deficiencies of existing conductive connection plates, the applicant improves through research, provides another kind of electric power grounding grid to draw the conductive connection plates of reaching the standard grade; Its contact area is big; Functional reliability is high, and guarantees that drawing the tube connector of reaching the standard grade is that quadrature is connected with binding, is easy to install.
The technical scheme of the utility model is following:
Electric power grounding grid draws the conductive connection plates of reaching the standard grade; Comprise binding and draw the tube connector of reaching the standard grade; One end of binding with draw the tube connector of reaching the standard grade and be welded to connect; Perforate is arranged on the binding, and said binding has breach with an end that draws the tube connector welding of reaching the standard grade, and said gap width is identical with the diameter that draws the tube connector of reaching the standard grade.
Its further technical scheme is: two perforates are arranged on the said binding, and one of them is a circular hole, and another is a mounting hole.
Its further technical scheme is: said binding has bending, and the both ends of the surface up and down of said bending are parallel.
The useful technique effect of the utility model is:
(1) four weld zone has increased binding and the contact area of drawing the tube connector of reaching the standard grade, and helps passing through rapidly of big electric current.
(2) the relative tube connector in each weld zone center of circle central authorities symmetry has guaranteed binding and the linearity of drawing the tube connector of reaching the standard grade.
(3) two circular bolt holes on the binding change a circular hole and a mounting hole into, have reduced difficulty of construction.

Embodiment
Further specify below in conjunction with the embodiment of accompanying drawing the utility model.
Like Fig. 5 ~ shown in Figure 7, the utility model discloses a kind of conductive connection plates, comprise binding 201 and draw the tube connector 202 of reaching the standard grade, an end of binding 201 with draw the tube connector 202 of reaching the standard grade and be welded to connect.See Fig. 4, there is a bending 205 at the middle part of binding 201, and this bending 205 is divided into two parallel end faces that the vertical height phase difference of half is drawn tube connector 202 diameters of reaching the standard grade with binding 201.Have on binding 201 upper surfaces and draw the breach 206 of the diameter same widths of the tube connector 202 of reaching the standard grade, have two bolt aperture on binding 201 lower surfaces, comprise a circular hole 204a and a mounting hole 204b.
Like Fig. 6, shown in Figure 7; Because the width of the breach 206 of binding 201 is identical with the diameter that draws the tube connector 202 of reaching the standard grade; Therefore draw the tube connector 202 of reaching the standard grade and just in time to insert breach 206 with its its maximum width at (diameter); The binding 201 of breach 206 both sides is fixed through electric welding with the diameter two ends of drawing the tube connector 202 of reaching the standard grade respectively, and weld zone 203 has four (see figure 7)s.Binding 201 and the contact area (positive and negative two of binding 201 have four weld seams) of drawing the tube connector 2 of reaching the standard grade have not only been increased; Help passing through rapidly of big electric current (like thunder and lightning); While is in the bus central authorities of drawing the tube connector 202 of reaching the standard grade owing to the weld zone rather than is partial to a side; The relative tube connector center of circle, each weld zone central authorities symmetry has guaranteed binding 201 and the linearity of drawing the tube connector 202 of reaching the standard grade.
As shown in Figure 6, two circular bolt holes on the binding 201 are changed into a circular hole 204a, a mounting hole 204b.When being connected, circular hole 204a is aimed at bolt on the bolt with the preformed hole on the electric power line pole tower earlier with electric power line pole tower; Then mounting hole 204b is aimed at bolt on the bolt with another preformed hole.Because mounting hole 204b is longer,,, can both reduce the difficulty of construction to last as long as error within the specific limits even the distance between two perforates is unequal on distance between two preformed holes therefore on the electric power line pole tower and the binding 201.
As shown in Figure 5, carry out bending at the middle part of binding 201, bending 205 is divided into conductive connection plates on two planes of height phase difference of half tube connector diameter.Because the utility model has been changed to bus central authorities with pad from a side of drawing tube connector 202 buses of reaching the standard grade; Formed the range difference of half tube connector diameter, so these bending 205 formed differences in height can just in time be offset the connection matching problem that the pad change is caused.
Above-described only is the preferred implementation of the utility model, and the utility model is not limited to above embodiment.Be appreciated that those skilled in the art not breaking away from other improvement and the variation of directly deriving or associating under the prerequisite that the utility model conceives basically, all should think to be included within the protection range of the utility model.
