Abstract
The invention relates to a grounding block welding structure. A T-shaped slot is arranged on a copper grounding block; and a stainless steel base plate is inserted into the T-shaped slot. The grounding block welding structure provided by the invention overcomes the shortcomings that in the traditional mode of connecting a copper grounding block and a GIS cabinet enclosure by a screw, the molten solder is non-sticky on the stainless steel in the gas welding process due to the difference expansion coefficients of the copper and the stainless steel, the temperature of the base metals of the two is difficult to control, cracks are easily generated at the welded joint of argon arc welding, consequently the risk of the grounding block dropping from the cabinet enclosure is increased, etc. According to the invention, the stainless steel base plate arranged in the T-shaped slot on the copper grounding block is welded with the stainless steel cabinet enclosure as a welding surface; and due to the same material, the welding is simple and reliable, and the problem that a copper grounding block is hard to be welded with a stainless steel cabinet enclosure is solved.
Description
Technical field
Involved in the present invention is a kind of Welding Structure, is a kind of earthing block Welding Structure of a kind of copper earthing block and stainless steel rack housing specifically.
Background technology
The GIS rack of outdoor use needs effective grounding because of it, needs to weld earthing block at the GIS rack enclosure.The material of earthing block is generally selected copper material, be called the copper earthing block, and the material of the G I S rack of outdoor use is generally selected stainless steel material.
Before the present invention, generally be that the copper earthing block is connected screw to connect with the GIS rack enclosure mode is fixed.The defective of this mode be need to be on the shell of rack processing mounting holes, thereby the waterproof ability of rack caused harmful effect; If earthing block is welded direct on the rack enclosure, welding procedure is difficult to control.Because copper has good heat-conducting effect, and stainless heat conductivity is poor, and both coefficients of expansion are also different, if adopt the gas welding welding, be easy to cause the scolder of melting in the process of welding sticking on stainless steel, controlling for the temperature of both mother metals also is difficult point; If the employing argon arc welding, the commissure easily cracks, and can increase the risk that earthing block and cabinet shell come off.
Summary of the invention
Purpose of the present invention just is to solve above-mentioned welding difficulty, design, a kind of earthing block Welding Structure of development.
Technical scheme of the present invention is:
A kind of earthing block Welding Structure, its technical characteristics are to arrange on the copper earthing block T-shaped groove, and along on the copper earthing block surface longitudinal T-shaped groove being set, the stainless steel backing plate is inserted in the T-shaped groove, stainless steel backing plate and housing welding.
Advantage of the present invention and effect are to be contained on the copper earthing block stainless steel backing plate in the T-shaped groove as solder side and the welding of stainless steel rack housing, because its material is identical, weld simple and reliable, thereby solved the problem that copper earthing block and stainless steel rack housing are difficult to weld.
Other concrete advantages of the present invention and effect will go on to say below.
Description of drawings
Fig. 1---Welding Structure schematic diagram of the present invention.
Fig. 2---copper earthing block and stainless steel rack housing welding schematic diagram.
Each label represents that corresponding component is as follows among the figure:
Stainless steel backing plate 1, copper earthing block 2, stainless steel rack housing 3, T-shaped groove 4, soldered 5.
Embodiment
As shown in Figure 1 and Figure 2:
Processing T type groove 4 on copper earthing block 2, namely along (carving) T-shaped groove 4 is set on copper earthing block 2 surface longitudinals, on cross section, namely can find out as shown in Figure 2 this T-shaped groove 4, then stainless steel backing plate 1 is inserted into T-shaped groove 4 the insides, stainless steel backing plate 1 outer surface is concordant with copper earthing block 2 cross sections.
Application process explanation of the present invention:
After stainless steel backing plate 1 is inserted in the T-shaped groove 4 and installs with copper earthing block 2 tight fits, T-shaped groove 4 opening surfaces with copper earthing block 2 contact with stainless steel rack housing 3 again, guarantee the plane of copper earthing block 2 with the plane close contact of stainless steel rack housing 3, the faying face (soldered 5 places among the figure) of a soldering stainless steel backing plate 1 and stainless steel rack housing 3 during welding.Like this, because the material of stainless steel backing plate 1 is identical with the material of stainless steel rack housing 3, therefore be easy to just the two to be welded, stainless steel backing plate 1 in the T-shaped groove 4 is pressed in copper earthing block 2 on the stainless steel rack housing 3 tightly simultaneously, guarantee the good contact of the two, thereby solved the problem that copper earthing block 2 and stainless steel rack housing 3 are difficult to weld.
Claims (3)
1. an earthing block Welding Structure is characterized in that arranging on the copper earthing block T-shaped groove, and along on the copper earthing block surface longitudinal T-shaped groove being set, the stainless steel backing plate is inserted in the T-shaped groove, stainless steel backing plate and housing welding.
2. a kind of earthing block Welding Structure according to claim 1 is characterized in that stainless steel backing plate and T-shaped groove tight fit.
