Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, specifically a tooling structure suitable for shielding and aligning shielded conductors. Background Technology

[0002] Currently, the alignment of shielding and shielded conductors is mainly achieved by manually measuring the phase spacing between shielded conductors and between shields.

[0003] The following problems exist with manually measuring phase spacing: 1. Since the distance between shielding conductors and between shields cannot be accurately determined, the error in manually measuring phase spacing is relatively large; 2. By measuring phase spacing, it cannot be guaranteed that the position of the shielding conductor relative to the isolation shell flange is consistent with the position of the shield relative to the disc insulator flange, resulting in poor alignment of the shielding conductor and the shield; 3. Using the method of measuring phase spacing requires a long time to measure and correct the fastening position of the shielding conductor and the shield, which is inefficient.

[0004] Therefore, it is necessary to design a tooling structure suitable for shielding and aligning shielded conductors to improve alignment accuracy and efficiency. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a tooling structure suitable for shielding and aligning shielded conductors, so as to improve alignment accuracy and efficiency.

[0006] To achieve the above objectives, this utility model provides a tooling structure suitable for shielding and aligning shielded conductors, including a shielding tooling and a shielded conductor tooling. The shielded conductor tooling includes a tooling positioning plate, a shielded conductor, and shielded conductor positioning blocks. The tooling positioning plate has fasteners at both ends for fixing to flanges of the isolation shell. The tooling positioning plate has a through hole and three mounting holes in its center, with the three mounting holes surrounding the through hole. The three shielded conductor positioning blocks are respectively installed in their corresponding mounting holes. The head of the shielded conductor is embedded in the tail of the shielded conductor positioning block. The tail of the shielding conductor has an assembly hole 1 for connection with the busbar conductor; the shielding fixture includes a fixture positioning plate 2, a shielding assembly structure, a fixture positioning pad, and a shielding positioning block. The two ends of the fixture positioning plate 2 are provided with fixture positioning pads for fixing to the disc insulator flange. The center of the fixture positioning plate 1 is provided with a through hole 2 and three mounting holes 2. The three mounting holes 2 surround the through hole 2. The three shielding positioning blocks are respectively installed in the corresponding mounting holes 2. The tail of the shielding positioning block is embedded in the head of the shielding assembly structure. The tail of the shielding assembly structure has an assembly hole 2 for connection with the disc insulator.

[0007] After passing through the tooling positioning plate, the fastener one is fixed to the flange of the isolation shell, and after passing through the bus conductor, the fastener two is fixed to the assembly hole of the shield conductor.

[0008] The tooling positioning pad includes a connecting rod and a pad body, with the pad body sleeved over the connecting rod.

[0009] The shielding assembly structure includes a shield, a spring contact finger, and a guide ring. The head of the shield has a mounting groove, and the inner wall of the mounting groove is fitted with a spring contact finger and a guide ring. The tail of the shield has two assembly holes.

[0010] The two ends of the connecting rod are fixed to the tooling positioning plate two and the disc insulator flange respectively. The pad body is located between the tooling positioning plate two and the disc insulator flange. After the fastener three passes through the disc insulator, it is fixed to the assembly hole two of the shield.

[0011] The tooling positioning plate one and the shielding conductor positioning block, and the tooling positioning plate two and the shielding positioning block are fixed with screws.

[0012] Compared with the prior art, this utility model ensures the position of the shield relative to the disc insulator flange by using shielding fixtures and the position of the shielding conductor relative to the isolation shell flange by using shielding conductor fixtures, thereby ensuring the accuracy of the alignment of the shield and the shielding conductor; the fixture alignment also saves time and is more efficient.

[0019] The present invention will now be further described with reference to the accompanying drawings.

[0020] See Figures 1-4This utility model is a tooling structure suitable for shielding and aligning shielded conductors, including a shielding tooling and a shielded conductor tooling. The shielded conductor tooling includes a tooling positioning plate 61, a shielded conductor 5, and shielded conductor positioning blocks 7. The tooling positioning plate 61 has fasteners at both ends for fixing to the flanges of the isolation housing 1. The tooling positioning plate 61 has a through hole and three mounting holes in its center, with the three mounting holes surrounding the through hole. The three shielded conductor positioning blocks 7 are respectively installed in their corresponding mounting holes. The head of the shielded conductor 5 is embedded in the tail of the shielded conductor positioning block 7, and the tail of the shielded conductor 5 has… The first assembly hole is connected to the bus conductor 4; the shielding fixture includes a second fixture positioning plate 62, a shielding assembly structure 8, a fixture positioning pad 9, and a shielding positioning block 10. The two ends of the second fixture positioning plate 62 are provided with fixture positioning pads 9 that are fixed to the disc insulator flange 3. The center of the first fixture positioning plate 61 is provided with a second through hole and three second mounting holes. The three second mounting holes surround the second through hole. The three second shielding positioning blocks 10 are respectively installed in the corresponding second mounting holes. The tail of the second shielding positioning block 10 is embedded in the head of the shielding assembly structure 8. The tail of the shielding assembly structure 8 has a second assembly hole connected to the disc insulator 2.

[0021] See Figure 5 The tooling positioning pad 9 includes a connecting rod 91 and a pad body 92, with the pad body 92 sleeved on the connecting rod 91.

[0022] See Figure 6 The shielding assembly structure 8 includes a shield 11, a spring contact finger 12, and a guide ring 13. The head of the shield 11 has a mounting groove, and the inner wall of the mounting groove is fitted with the spring contact finger 12 and the guide ring 13. The tail of the shield 11 has a mounting hole. When installing the shielding positioning block 10, the guide ring 13 acts as a guide, and the spring contact finger 12 acts as a compression positioning element. After the shielding positioning block 10 is embedded in the shielding assembly structure 8, the shielding positioning block 10 compresses the spring contact finger 12, and the spring contact finger 12 applies the compression force evenly to the shield 11, thereby achieving the positioning function.

[0023] For ease of installation, the tooling positioning plate 61 and the shielding conductor positioning block 7, and the tooling positioning plate 62 and the shielding positioning block 10 are fixed with screws.

[0024] Since the shielded conductor fixture adopts the structure of fixture positioning plate 61 and shielded conductor positioning block 7, it can adapt to the installation of shielded conductors 5 with different phase spacing by replacing fixture positioning plate 61, and it can also adapt to shielded conductors 5 with different sizes by replacing shielded conductor positioning block 7.

[0025] Similarly, since the shielding fixture adopts the structure of fixture positioning plate 2 62 and shielding positioning block 10, it can adapt to the installation of shields 11 with different phase spacing by replacing fixture positioning plate 2 62, and it can also adapt to shields 11 with different sizes by replacing shielding positioning block 10.

[0026] In operation, fastener one passes through tooling positioning plate one 61 and is fixed to the flange of the isolation housing 1, ensuring the position of the shielding conductor 5 relative to the flange of the isolation housing 1. Fastener two passes through the busbar conductor 4 and is fixed to the first assembly hole of the shielding conductor 5, thus securing the shielding conductor 5 to the busbar conductor 4. Next, both ends of the connecting rod 91 are fixed to tooling positioning plate two 62 and disc insulator flange 3 respectively, ensuring the position of the shield 11 relative to the disc insulator flange 3. The pad body 92 is located between tooling positioning plate two 62 and disc insulator flange 3. Fastener three passes through the disc insulator 2 and is fixed to the second assembly hole of the shield 11, thus securing the shield 11 to the disc insulator 2. The installation of the shielding conductor 5 and the shield 11 is completed, thus achieving the alignment of the shielding and the shielding conductor.

[0027] This invention uses a shielding fixture to ensure the position of the shield relative to the disc insulator flange, and a shielding conductor fixture to ensure the position of the shielding conductor relative to the isolation housing flange, thereby ensuring the accuracy of the alignment of the shield and the shielding conductor; the fixture alignment also saves time and is more efficient.
