[0052] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.
[0053] Reference Figures 1-5 This embodiment provides a partition, including a base 100, which is an integrally formed plate-shaped object. The base 100 is square plate-shaped, and its four sides are arc-shaped transitions.
[0054] The base 100 has a mounting hole 101 at its center, through which an insulating sleeve 400 passes. 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 5As shown in the figure, the shape of the mounting hole 101 is a regular hexagon, and the base body 100 outside the mounting hole 101 is also provided with an annular convex body 105, and the distance between the parallel two sides of the mounting hole 101 is d1, wherein d1 = 19.5 mm; the outer diameter of the convex body 105 is d2, wherein d2 = 25 mm, and the height of the convex body 105 is h1, wherein h1 = 2 mm.
[0056] The base body 100 includes at least one insulating side 102, wherein the insulating side 102 prevents arc discharge. Since the base body 100 includes upper and lower planes, as shown in the figure, Figure 2 When both sides of the base body 100 need to be attached to the conductive plate 200 to prevent arc discharge, both sides of the base body 100 are insulating sides 102, as shown in the figure, Figure 3 When only one side of the base body 100 needs to be attached to the conductive plate 200 to prevent arc discharge, the side that prevents arc discharge is the insulating side 102.
[0057] As shown in the figure, Figure 1 and Figure 4 The insulating side 102 includes three convex strip rings 103, and there is a recessed groove 104 between every two adjacent convex strip rings 103, wherein the thickness of the base body 100 is 7.4 mm, and the top of the convex strip ring 103 and the starting surface are h2, and the bottom of the recessed groove 104 and the starting surface are h3, wherein h2 = h3 = 1.5 mm.
[0058] The two side walls of the recessed groove 104 are respectively collinear with the adjacent convex strip rings 103, that is, the bottom between every two adjacent convex strip rings 103 is the recessed groove 104, wherein the convex strip ring 103 and the recessed groove 104 are square, and the corners are transitioned through arcs.
[0059] Among them, the three convex strip rings 103 are respectively an inner ring one 103a, a middle ring two 103b, and an outer ring three 103c; wherein the distance from the outer side of the ring three 103c to the outer side of the base body 100 is d3, the width of the ring three 103c is d4, and the width of the ring two 103b, the ring three 103c and the recessed groove is d5, wherein d3 = 2.5 mm, d4 = 2 mm, and d5 = 3 mm.
[0060] As shown in the figure, Figure 4 The ring three 103c includes two vertical edges and a horizontal top edge, wherein the outer vertical edge is directly connected with the horizontal top edge, and the inner vertical edge is connected with the horizontal top edge through an arc transition;
[0061] The ring two 103b includes two vertical edges and a horizontal top edge, wherein the horizontal top edge is connected with the two vertical edges through an arc transition;
[0062] Ring 103a includes two vertical sides and a top horizontal side, wherein the inner vertical side is directly connected to the top horizontal side, and the outer vertical side is connected to the top horizontal side by an arc transition.
[0063] The two recessed grooves 104 include two vertical sides and a horizontal side at the bottom, wherein the horizontal side at the bottom is connected to the two vertical sides by an arc transition; wherein the vertical sides of the two recessed grooves 104 are collinear with the vertical sides of their adjacent ring 103a, ring 2 103b or ring 3 103c.
[0064] The creepage distance between the three raised rings 103 and the two recessed 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 raised rings 103 and the two recessed grooves 104 can meet the creepage distance requirements, provide better heat dissipation, meet the requirements of use under harsh industrial conditions, save costs, and extend the service life of the substrate 100.
[0065] Reference Figures 6-8 This is the second embodiment of the present invention, which provides a partition. The difference between this embodiment and the first embodiment is that the convex ring 103 is divided into two parallel side 102a and side 202b, side 102a and side 202b are perpendicular to each other, and the connection between side 102a and side 202b is through an arc transition.
[0066] Among them, such as Figure 8 As shown, the width of ring 103a located on side 102a is d5, where d5 = 3mm;
[0067] Among them, such as Figure 7 As shown, the width of ring 103a located on side 2 102b is d6, d6 = 2.5mm.
[0068] The creepage distance between the three raised rings 103 and the two recessed grooves 104 at side 1 102a is 77.4 mm, and the electrical clearance is 47.4 mm. The creepage distance between the three raised rings 103 and the two recessed grooves 104 at 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 103a on side 102a and the ring 103a on side 202b can meet the error of material cutting in actual production.
[0070] Reference Figures 9-11 The third embodiment of this utility model provides a conductor, which includes a separator and a conductive plate 200, wherein the insulating side 102 of the substrate 100 is attached to one side of the conductive plate 200.
[0071] like Figure 9As 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 Figure 10 As shown, when the substrate 100 has an insulating side 102, that is, when a conductive plate 200 is attached to one side of the substrate 100.
[0073] The conductive plate 200 is plate-shaped, and its length and width are smaller than the width and length of the inner side of the ring 103a. The conductive plate 200 has a through hole 201 at its center, and the shape of the through hole 201 is consistent with the shape of the mounting hole 101. The through hole 201 allows the insulating sleeve 400 to pass through.
[0074] Furthermore, a fluidized insulating layer 202 is annularly wrapped around the outer side of the middle part of the conductive plate 200 to improve the insulation effect of the conductive plate 200. The position where the fluidized insulating layer 202 protrudes from the perforation 201 is not wrapped. The overall heat dissipation effect of the conductive plate 200 is better because it is wrapped with the fluidized insulating layer 202.
[0075] like Figure 11 As shown, a slot 106 is provided on the base 100 on the outer side of the protrusion 105. The slot 106 has a depth of 1mm and is used for the fluidized insulating layer 202 to be inserted. The creepage distance between the slot 106 and the protrusion 105 is 70mm and the electrical clearance is 67mm.
[0076] Reference Figures 12-14 The fourth embodiment of this utility model provides a connector, which includes conductors and clamping plates 300. Two clamping plates 300 are provided, and multiple conductors are provided between the two clamping plates 300. The multiple conductors are stacked between the two clamping plates 300. According to the different number of internal connecting cables of existing connectors, it is divided into five-wire system and four-wire system. 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 Figure 12 As shown, it is a five-wire system with five conductors. The base 100 of the top conductor has one insulating side 102, and the base 100 of the remaining conductors has two insulating sides 102.
[0078] like Figure 13 As shown, it is a four-wire system with a total of five conductors. The base 100 of the conductors at the top and bottom have an insulating side 102, and the two insulating sides 102 are arranged close to each other. The base 100 of the remaining conductors also has two insulating sides 102.
[0079] The connector also includes an insulating sleeve 400, which passes through a plurality of stacked conductors;
[0080] Also include bolt 500 and nut 600, bolt 500 through two clamping plate 300 and between the insulating sleeve 400, nut 600 with bolt 500 end connection, and with one of the clamping plate 300 with the contact, so that the two clamping plate 300 between the conductor is clamped and fixed.
