[0051] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with specific implementation methods and drawings.

[0052] The terms used in the present invention are those general terms currently widely used in the art in consideration of the functions of the present invention, but these terms may vary according to the intention of a person of ordinary skill in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in this case, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as a general description based on the meaning of the terms and the present invention.

[0053] Reference Figure 1-Figure 5 The present embodiment provides a partition, including a substrate 100, wherein the substrate 100 is an integrally formed plate-shaped object, wherein the substrate 100 is a square plate-shaped object, and the four sides of the substrate 100 are arc-shaped transitions.

[0054] A mounting hole 101 is provided at the center of the base 100 , wherein the mounting hole 101 is used for the insulating sleeve 400 to pass through. The insulating sleeve 400 is a component of the connector and is used to limit and fix the base 100 .

[0055] like Figure 1 , Figure 2 and Figure 5 As shown, the shape of the mounting hole 101 is a regular hexagon, and an annular protrusion 105 is also provided on the base 100 outside the mounting hole 101, and the distance between the two parallel sides of the mounting hole 101 is d1, where d1 = 19.5 mm; the outer diameter of the protrusion 105 is d2, where d2 = 25 mm, and the height of the protrusion 105 is h1, where h1 = 2 mm.

[0056] The substrate 100 includes at least one insulating side 102, wherein the insulating side 102 is used to prevent arc discharge. Since the substrate 100 includes two upper and lower planes, such as Figure 2 When both sides of the substrate 100 need to be attached to the conductive plate 200 to prevent arc discharge, both sides of the substrate 100 are insulating sides 102. Figure 3 When only one side of the substrate 100 needs to be attached to the conductive plate 200 to prevent arc discharge, the side to prevent arc discharge is the insulating side 102 .

[0057] like Figure 1 and Figure 4 The insulating side 102 shown includes three convex rings 103, and there is a concave groove 104 between every two convex rings 103, wherein the thickness of the substrate 100 is 7.4 mm, and the surface of the substrate 100 is taken as the starting surface, wherein the difference between the top of the convex ring 103 and the starting surface is h2, and the difference between the bottom of the concave groove 104 and the starting surface is h3, wherein h2=h3=1.5 mm.

[0058] The two side walls of the recessed groove 104 are respectively colinear with the adjacent convex rings 103 , that is, the bottom between each two adjacent convex rings 103 is the recessed groove 104 , wherein the convex rings 103 and the recessed groove 104 are square, and the corners are transitioned through arcs.

[0059] Among them, the three convex rings 103 are respectively the inner ring 103a, the middle ring 2 103b, and the outer ring 3 103c; the distance from the outer edge of the ring 3 103c to the outer edge of the substrate 100 is d3, the width of the ring 3 103c is d4, the widths of the ring 2 103b, the ring 3 103c and the Austrian line groove are d5, wherein d3=2.5mm, d4=2mm, d5=3mm.

[0060] like Figure 4 As shown, the ring 3 103c includes two vertical edges and a horizontal edge at the top, wherein the outer vertical edge is directly connected to the horizontal edge at the top, and the inner vertical edge is connected to the horizontal edge at the top through an arc transition;

[0061] Ring 2 103b includes two vertical edges and a horizontal edge at the top, wherein the horizontal edge at the top is connected to the two vertical edges by an arc transition;

[0062] Ring 1 103a includes two vertical sides and a horizontal side at the top, wherein the inner vertical side is directly connected to the horizontal side at the top, and the outer vertical side is connected to the horizontal side at the top through an arc transition;

[0063] The two recessed grooves 104 include two vertical edges and a horizontal edge at the bottom, wherein the horizontal edge at the bottom is connected to the two vertical edges by an arc transition; wherein the vertical edges of the two recessed grooves 104 are collinear with the vertical edges of the adjacent ring 1 103a, ring 2 103b or ring 3 103c.

[0064] The creepage distance between the three convex rings 103 and the two concave grooves 104 is 77.4 mm, and the electrical clearance is 47.4 mm. The thickness of the substrate 100 and the dimensions of the three convex rings 103 and the two concave grooves 104 can meet the creepage distance and have better heat dissipation effect, meet the use under harsh industrial conditions, save costs, and extend the service life of the substrate 100.

[0065] Reference Figure 6-Figure 8 , which is the second embodiment of the present invention, provides a partition. The difference between this embodiment and the first embodiment is that the convex ring 103 is divided into two parallel side edges 102a and 102b, the side edge 102a and the side edge 102b are perpendicular, and the connection between the side edge 102a and the side edge 102b is through an arc transition.

[0066] Among them, Figure 8 As shown, the width of the ring 103a located at the side 102a is d5, d5 = 3mm;

[0067] Among them, Figure 7 As shown, the width of the ring 1 103a located at the side 2 102b is d6, d6 = 2.5 mm.

[0068] The creepage distance between the three protruding rings 103 and the two recessed grooves 104 at the side 102a is 77.4 mm, and the electrical clearance is 47.4 mm. The creepage distance between the three protruding rings 103 and the two recessed grooves 104 at the side 2 102b is 72.4 mm, and the electrical clearance is 42.4 mm.

[0069] The differentiated setting of the width of the ring 1 103a of the side 102a and the ring 1 103a of the side 2 102b can meet the error of cutting materials in actual production.

[0070] Reference Figure 9-11 , which is a third embodiment of the present invention, provides a conductor, which includes a separator and a conductive plate 200, and the insulating side 102 of the substrate 100 is attached to one side of the conductive plate 200;

[0071] like Fig. 9 As shown, when the substrate 100 has two insulating sides 102 , that is, a conductive plate 200 is attached to both sides of the substrate 100 .

[0072] like Fig.10As shown, when the substrate 100 has an insulating side 102, that is, the substrate 100 is attached to a conductive plate 200 on one side.

[0073] The conductive plate 200 is in a plate shape, and its length and width are smaller than the width and length of the inner side of the ring 103a. A through hole 201 is provided at the center of the conductive plate 200. The shape of the through hole 201 is consistent with the shape of the mounting hole 101, and the through hole 201 can allow the insulating sleeve 400 to pass through.

[0074] Furthermore, the outer middle part of the conductive plate 200 is annularly wrapped with a fluidized insulating layer 202 to improve the insulation effect of the conductive plate 200. The position where the fluidized insulating layer 202 leaks out of the perforation 201 is not wrapped. The conductive plate 200 wraps the fluidized insulating layer 202, and its overall heat dissipation effect is better.

[0075] like Fig.11 As shown, a slot 106 is provided on the base 100 outside the protrusion 105. The depth of the slot 106 is 1 mm. The slot 106 is used for plugging the fluidized insulating layer 202. The creepage distance between the slot 106 and the protrusion 105 is 70 mm, and the electrical clearance is 67 mm.

[0076] Reference Figure 12-14 , which is the fourth embodiment of the present invention, provides a connector, which includes a conductor and a clamping plate 300, wherein two clamping plates 300 are provided, and a plurality of conductors are provided between the two clamping plates 300, and the plurality of conductors are stacked between the two clamping plates 300, wherein the existing connector is divided into a five-wire system and a four-wire system according to the number of cables connected inside the connector, wherein the five-wire system means that five cables can be connected between the two clamping plates 300, and the four-wire system means that four cables are provided between the two clamping plates 300.

[0077] like Fig.12 As shown, it is a five-wire system with five conductors in total. The base body 100 in the top conductor has one insulating side 102 , and the base bodies 100 in the remaining conductors have two insulating sides 102 .

[0078] like Fig.13 As shown, it is a four-wire system with five conductors in total. The substrate 100 in the conductors at the top and bottom ends has one insulating side 102 , and the two insulating sides 102 are arranged close to each other. The substrate 100 in the remaining conductors has two insulating sides 102 .

[0079] The connector further includes an insulating sleeve 400, wherein the insulating sleeve 400 passes through a plurality of conductors arranged in a stacked manner;

[0080] It also includes a bolt 500 and a nut 600. The bolt 500 passes through the two clamping plates 300 and the insulating sleeve 400 therebetween. The nut 600 is connected to the end of the bolt 500 and contacts one of the clamping plates 300, thereby clamping and fixing the conductor between the two clamping plates 300.

[0081] like Fig.14 FIG. 1 is a comparison of the temperature rise effects of the connector of the present invention and the prior art connector. The effect of the present invention is far superior to that of the prior art.

[0082] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it.
