DETAILED DESCRIPTION

[0027] The following will be described in detail with reference to the accompanying drawings Figs. 1-3 The application is further described in detail.

[0028] Example 1

[0029] The application discloses an insulating structure for mounting the tail of an electric heating tube resistor 10. Referring to Figs. 1-3 , two mounting pillars 1 are fixedly mounted on the rack of a power detection device, and a plurality of insulating support plates 2 are detachably mounted between the two mounting pillars 1. The top of each insulating support plate 2 is provided with a plurality of first placing grooves 21 for placing the electric heating tube resistor 10. Insulating connecting structures are arranged between the two ends of the insulating support plate 2 and the two mounting pillars 1.

[0030] The bottom of the electric heating tube resistor 10 is embedded in the first placing groove 21. The first placing groove 21 can limit the position of the electric heating tube resistor 10, reduce the displacement of the electric heating tube resistor 10, and effectively improve the stability of the installation of the electric heating tube resistor 10. Since the electric heating tube resistor 10 only directly contacts the insulating support plate 2 and does not directly contact the metal plate, a first double insulating isolation is formed. Moreover, since the two ends of the insulating support plate 2 are connected to the mounting pillars 1 through the insulating connecting structures, a second double insulating isolation is formed. The insulating performance of the mounting structure of the electric heating tube resistor 10 is effectively improved, and the safety and reliability of the power detection device are effectively guaranteed.

[0031] Referring to Fig. 3 , a first jack 22 is formed at each end of the insulating support plate 2, and a plurality of second jacks 11 are formed on the two mounting pillars 1. The insulating connecting structure includes a concave porcelain piece 4, a protruding porcelain piece 3, a mounting bolt 8, and a locking nut 81. The protruding porcelain piece 3 includes a protruding pipe portion. A groove is formed on one side of the concave porcelain piece 4, which is matched with the protruding pipe portion. The protruding pipe portion penetrates the first jack 22 and extends into the groove.

[0032] A first mounting hole 41 is formed through the concave porcelain piece 4, and a second mounting hole 31 is formed through the protruding porcelain piece 3. The rod portion of the mounting bolt 8 penetrates the first mounting hole 41, the first jack 22, the second mounting hole 31, and the second jack 11 in sequence and then extends to the outside of the mounting pillar 1. The locking nut 81 is threadedly mounted on the rod portion of the mounting bolt 8 extending out of the second jack 11. The insulating support plate 2 is tightly arranged between the concave porcelain piece 4 and the protruding porcelain piece 3.

[0033] Through the mutual cooperation and use between the concave porcelain piece 4, the convex porcelain piece 3, the mounting bolt 8 and the locking nut 81, the two ends of the insulating support plate 2 can be fixed on the mounting pillar 1 through the concave porcelain piece 4 and the convex porcelain piece 3. Since the concave porcelain piece 4 and the convex porcelain piece 3 both have good insulation performance, the insulating support plate 2 can be connected between the two ends of the mounting pillar 1 in an insulated manner, thereby forming secondary insulation isolation protection for the electric heating tube resistor 10 and further improving the insulation performance of the electric heating tube resistor 10.

[0034] With reference to Fig. 1 With Fig. 2 , the front and rear sides of the insulating support plate 2 are respectively detachably mounted with the first and second backing plates 5, and the two ends of the first and second backing plates 5 are respectively provided with through holes for the rod part of the mounting bolt 8 to extend out.

[0035] The first and second backing plates 5 are respectively arranged on the front and rear sides of the insulating support plate 2, which can increase the contact area between the concave porcelain piece 4, the convex porcelain piece 3 and the insulating support plate 2, reduce the damage to the insulating support plate 2 caused by pressure, and provide good protection effect for the insulating support plate 2.

[0036] With reference to Fig. 1 With Fig. 2 In the embodiment of the application, the first and second backing plates 5 are both mounted on the two sides of the insulating support plate 2 through the fixing bolts 9.

[0037] With reference to Fig. 2 The tube part of the mounting bolt 8 is sleeved with the silica gel sleeve 6.

[0038] The silica gel sleeve 6 is sleeved on the rod part of the mounting bolt 8, and abuts against the rod part of the mounting bolt 8 and the first and second mounting holes 41 and 31, which can improve the stability of the threaded connection of the mounting bolt 8 and reduce the damage to the concave porcelain piece 4 and the convex porcelain piece 3.

[0039] The implementation principle of the tail mounting insulation structure of the electric heating tube resistor 10 is that the bottom of the electric heating tube resistor 10 is embedded in the first placement groove 21, the first placement groove 21 can limit the position of the electric heating tube resistor 10, reduce the displacement of the electric heating tube resistor 10, and effectively improve the stability of the electric heating tube resistor 10; since the electric heating tube resistor 10 only directly contacts the insulating support plate 2 and does not directly contact the metal plate, a first heavy insulation isolation can be formed; by matching and using the concave porcelain piece 4, the convex porcelain piece 3, the mounting bolt 8 and the locking nut 81, the two ends of the insulating support plate 2 can be fixed on the mounting pillar 1 through the concave porcelain piece 4 and the convex porcelain piece 3; since the concave porcelain piece 4 and the convex porcelain piece 3 have good insulation performance, the insulating support plate 2 can be connected between the two ends of the insulating support plate 2 and the mounting pillar 1, a secondary insulation isolation protection of the electric heating tube resistor 10 is formed, and the insulation performance of the electric heating tube resistor 10 is further improved.
