Description

Technical Field

[0001] This application relates to the technical field of copper busbar insulating paper, and in particular to a novel insulating paper structure. Background Art

[0002] Currently, conductors in servo drives mostly use copper busbars or aluminum busbars. To achieve the purpose of insulating each phase, either the distance between each phase of copper busbars is increased, or insulating paper is added between the copper busbars to achieve the insulating effect. The way of adding insulating paper is to add a layer of insulating paper between phases, and then press it at the edge or press the insulating paper tightly through the copper busbar to achieve the purpose of fixing the insulating paper. The fixing method of pressing the insulating paper at the edge or by the copper busbar may cause damage or detachment of the insulating paper, and using multiple insulating papers to separate the copper busbars may increase the complexity of assembly, requiring precise alignment and fixation to ensure good insulating effect. Summary of the Utility Model

[0003] This application provides a novel insulating paper structure, achieving the effects of simple manufacturing process and cost saving.

[0004] The novel insulating paper structure provided by this application adopts the following technical solutions:

[0005] A novel insulating paper structure includes an insulating paper body formed by folding an insulating paper back and forth. The insulating paper body includes a plurality of insulating partitions arranged at intervals front and back. A gap for placing a copper busbar is provided between any two adjacent insulating partitions. A plurality of channels are provided on the insulating paper body for the copper busbar to be inserted from the frontmost insulating partition into any one of the gaps.

[0006] Further improvement, each of the gaps is at least provided with two of the channels, and the two channels are distributed at intervals on the left and right sides of the insulating paper body.

[0007] Further improvement, each of the channels is configured such that aligned slot holes are opened on all the insulating partitions passed through.

[0015] In summary, the present application includes at least one of the following beneficial technical effects:

[0016] 1. In the present utility model, an insulating paper is bent, and each phase of copper busbar or aluminum busbar is respectively placed in the gap of the bent insulating paper, so that insulation between phases is also achieved, reducing the assembly requirement of multiple insulating papers, simplifying the design of the insulation structure. The bent portion integrally and fixedly connects adjacent insulating spacers, improving the stability and reliability of the insulating paper structure, and reducing the risk of damage or detachment of the insulating paper caused by edge pressing or copper busbar pressing.

[0017] 2. Each gap is specially designed with a channel for the copper busbar to pass through. Passing the copper busbar through this hole can achieve the purpose of fixing the insulating paper, reducing the risk of damage and detachment of the insulating paper, and improving the safety of the electrical system.

The simplified structure and reduced assembly requirements help reduce material and labor costs and improve economic benefits. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0024] The following further elaborates on this application Figures 1-4 in conjunction with the attached drawings.

[0025] An embodiment of this application discloses a novel insulating paper structure.

[0026] Referring to Figure 1 , it includes an insulating paper body formed by folding a piece of insulating paper back and forth. The insulating paper body includes a plurality of insulating spacers 100 arranged at intervals front and back. A gap 300 for placing copper bars is provided between any two adjacent insulating spacers 100. A plurality of channels 400 are provided on the insulating paper body for the copper bars to be inserted from the frontmost insulating spacer 100 into any one of the gaps 300.

[0027] The design of the channel 400 allows the copper bar to pass through the insulating spacer 100 and at the same time provides a method for fixing the insulating paper. The channel 400 runs through and communicates with the gap 300 to the outside, which means that the copper bar can pass through the channel 400 from one side of the insulating paper structure for wiring and then be placed in the gap 300 to achieve assembly. Through the cooperation of the channel 400 and the gap 300, the copper bar is fixed between the insulating spacers 100 while maintaining the insulation performance between the phase copper bars.

[0028] As shown in the attached Figures 3-4 drawings, the above technical solution forms a busbar structure through the bending of the insulating paper and the cooperation of the channels, assembles and fixes with the copper bar, and at the same time utilizes the insulating characteristics of the insulating spacer 100 to achieve the purpose of isolating the phase copper bars. Each of the gaps is provided with at least two of the channels, and the two channels are distributed at intervals on the left and right sides of the insulating paper body. This one-side-two-hole structure design reduces the possible detachment problem caused by the traditional insulating paper fixing method and improves the insulation effect and electrical safety. Each of the channels is configured such that aligned slot holes are opened on all the insulating spacers passed through. Ensure that the assembly of the insulating paper and the copper bar is neater and not prone to dislocation. The channel 400 is composed of aligned holes or notches on one or more spaced insulating spacers 100 for subsequent connection or assembly work.

[0029] Referring to the attached Figure 2 , the insulation paper structures respectively adapted to different numbers of copper bars (or aluminum bars) will be described in detail below.

[0030] 1. Insulation paper structure adapted to a single copper bar: The first two of the insulation spacers 100 are respectively denoted as the first spacer 101 and the second spacer 102. The channel 400 includes a first left A hole 401 and a first right A hole 402 provided on the first spacer 101. The design of the first left A hole 401 and the first right A hole 402 allows both ends of the first copper bar 301 to pass through the first spacer 101, thereby realizing the assembly and positioning of the copper bar. This design simplifies the installation process of the copper bar because only the first copper bar 301 needs to be inserted into the gap 300 and fixed through the channel 400, without the need for additional fastening or pressing operations. Through precise channel positioning and fixation, the position of the copper bar is strictly controlled, reducing potential safety hazards caused by copper bar displacement or vibration. When the copper bar is placed in the gap 300, the copper bar is installed between the first spacer 101 and the second spacer 102, and effective insulation isolation is formed between both sides of the copper bar and other phases or conductive components, preventing the risk of electric arc or short circuit. The above design of the insulation paper structure is applicable to electrical application scenarios for accommodating a single copper bar or multiple copper bars arranged side by side.

[0031] 2. Insulation paper structure adapted to two copper bars: The third insulation spacer 100 is denoted as the third spacer 103. The channel 400 includes a second left B hole 403 and a second right B hole 404 provided on the second spacer 102. Similar to the adaptation of a single copper bar, the adaptation of two copper bars also simplifies the installation process. Only the copper bars need to be inserted into the corresponding gaps and fixed through the channels. The first copper bar is fixed through the first left A hole 401 and the first right A hole 402 on the first spacer 101, while the second copper bar is fixed through the second left B hole 403 and the second right B hole 404 on the second spacer 102. The above design of the insulation paper structure is applicable to electrical application scenarios where two copper bars are in a group or multiple groups of copper bars are arranged side by side.

[0032] To improve the insulation performance at both ends of the second copper bar 302 and the fixation performance of the insulation paper, the channel 400 further includes a first left B hole 405 and a first right B hole 406 provided on the first spacer 101. The first left B hole 405 is aligned with the second left B hole 403, and the first right B hole 406 is aligned with the second right B hole 404. This alignment design allows both ends of the copper bar to pass through two insulation spacers simultaneously and be assembled through the B-group channels, providing better fixation and insulation effects.

[0033] 3. Insulating paper structure adapted to three busbars: The fourth insulating spacer 100 is denoted as the fourth spacer 104. The channel 400 includes a third left C-hole 407 and a third right C-hole 408 provided on the third spacer 103. Similar to the adaptation for one or two busbars, the adaptation for three busbars also simplifies the installation process. To install the third busbar into the corresponding gap, it is only necessary to assemble it through the third left C-hole 407 and the third right C-hole 408. The design of the above-mentioned insulating paper structure is applicable to electrical application scenarios where three busbars are grouped or multiple groups of busbars are arranged side by side.

[0034] Similarly, in order to further improve the insulation performance at both ends of the third busbar and the fixing performance of the insulating paper, the channel 400 further includes a first left C-hole 409 and a first right C-hole 410 provided on the first spacer 101, and a second left C-hole 411 and a second right C-hole 412 provided on the second spacer 102. The first left C-hole 409, the second left C-hole 411 are aligned with the third left C-hole 407, and the first right C-hole 410, the second right C-hole 412 are aligned with the third right C-hole 408. When installing the third busbar 303, it is assembled by passing through the C-group channels on the first spacer 101 and the second spacer 102 correspondingly.

[0035] The insulating paper structure adapted to more than three busbars can be deduced by analogy.

[0036] In actual use, some busbars are U-shaped. When multiple U-shaped busbars are horizontally installed and fixed on the connection terminals in the servo drive, both ends of the busbars face the same side. To adapt to the installation method of the busbars, the closer the gap 300 corresponding to the channel 400 is to the rear, the closer the position of the channel 400 is to the end of the insulating spacer 100. That is, the first left A-hole 401, the second left B-hole 403, and the third left C-hole 407 are spaced apart from right to left in sequence, and the first right A-hole 402, the second right B-hole 404, and the third right C-hole 408 are spaced apart from left to right in sequence. The channels in the insulating paper structure are specially designed to be spaced apart from one side to the other in sequence. Both ends of the U-shaped busbar can pass through the corresponding left and right channels respectively to achieve the fixation and positioning of the insulating paper. Necessary insulation distances are maintained between the busbars and between the busbars and other components, improving the insulation performance. The spaced-apart distribution design of the channels allows the busbars to be adjusted according to actual installation requirements, providing a certain degree of flexibility and adaptability.

[0037] As shown in the Figures 3-4 attachment, all the slot holes opened on the insulating spacer passed through by one of the channels are first slot holes extending horizontally (such as Figure 3 the slot hole on the right). All the slot holes opened on the insulating spacer passed through by one of the channels are second slot holes extending vertically (such as Figure 3The slot on the left). That is, the groove type of the channel 400 is a horizontal groove or a vertical groove. Different groove types can meet the installation requirements in different directions. For example, a horizontal groove may be more suitable for horizontally installed copper bars, while a vertical groove may be more suitable for vertically installed copper bars. A specific groove design can simplify the assembly process, making the installation of copper bars more intuitive and easier. It is also convenient to ensure the gap between the two ends of the copper bar, thereby improving the insulation performance and reducing the risk of electric arc or short circuit. The channels 400 on the left and right sides of the insulating spacer 100 adopt different groove types. This differential design can provide an additional fixing mechanism, and the insulating paper structure can be stably positioned by using three mutually perpendicular planes of the copper bar. The left and right sections of the copper bar pass through the first slot hole and the second slot hole, and the middle section is placed in the gap.

[0038] As shown in the appendix Figure 2 As shown, all the slot holes opened on the insulating spacer passed through by one of the channels are notch structures provided at the edge of the insulating spacer. The slot holes at the leftmost end of the insulating paper (i.e., the first left C hole 409, the second left C hole 411, and the third left C hole 407) open to the left, and the inner slot holes (i.e., the first left A hole 401 and the first left B hole 405) open downward. The notch structure is located at the edge after the insulating paper is unfolded, similar to the contour of the letter "U". This shape helps the insertion and fixation of the copper bar, making the channel 400 easy to align and receive the end of the copper bar. The copper bar can be inserted into the channel more easily, simplifying the installation process. If maintenance or replacement of the copper bar is required, the notch structure can facilitate the disassembly of the copper bar. In actual use, the staff can design and adjust the notch structure according to the size and shape of the copper bar to meet different installation requirements.

[0039] As shown in the appendix Figure 2 As described, all the insulating spacers are parallel to each other and aligned with each other. All the insulating spacers should be horizontally aligned and vertically aligned. The bottom of the groove of the gap 300 is a bent portion 200. Any two adjacent insulating spacers are connected by the bent portion, and each bent portion is perpendicular to the two insulating spacers it connects. The groove type of the gap 300 is a U shape, and the bent insulating paper is in a wavy structure. For the convenience of cutting and manufacturing, the insulating spacer 100 is a quadrilateral with a pair of opposite sides parallel, and the bent portion 200 is arranged on the opposite sides of the quadrilateral. This design provides flexibility, and the geometric shape to be cut of the insulating spacer can be adjusted according to the size and shape of the copper bar and the required insulation requirements. And it allows it to adapt to different installation requirements. For example, the parallel opposite sides can be used to accommodate copper bars with a larger width, providing additional height to adapt to the height or gap of the copper bar. By using quadrilateral insulating spacers and setting the position of the bent portion, the manufacturing process of the insulating paper structure can be simplified while maintaining the stability and functionality of the structure.

[0040] The depth of the gap 300 is greater than the width of the copper bar, that is, the width of the insulating spacer 100 is greater than the width of the copper bar, which can fully accommodate and wrap the copper bar. There is a gap between the bent portion 200 and the copper bar, which plays a role of safety isolation to avoid touching the upper and lower sides of the copper bar.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
