Description

Technical Field

[0001] This utility model relates to the field of transformer wiring technology, specifically a wiring fixing structure for a small transformer. Background Technology

[0002] Small transformers typically refer to single-phase transformers with a capacity of less than 1 kVA. They are characterized by their small size, low cost, and minimal wiring requirements. They are commonly used in factory electrical control systems, power plant control, monitoring, and automatic circuits. When connecting the transformer to other equipment, the wiring is completed by aligning the fixing clip at one end of the wire with the terminal block and installing the fixing clip on the base using screws or other methods.

[0003] However, after the wiring is completed, since the connecting wires extend from the terminal block to the outside, workers may accidentally touch and pull the wires during inspection and maintenance, which will directly affect the connection between the fixing clip and the terminal block, potentially causing the wires to loosen or fall off, resulting in poor contact. Utility Model Content

[0004] The purpose of this utility model is to provide a wiring fixing structure for a small transformer to solve the problems mentioned in the background art.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figure 1 and Figure 5 As shown, in this embodiment, a wiring fixing structure for a small transformer includes a small transformer body 1. Connecting plates 2 are fixedly connected to the front and rear sides of the small transformer body 1. An upper clamping plate 3 is fixedly connected to the bottom end of the connecting plate 2. A sliding rod 4 is fixedly connected to the bottom end of the upper clamping plate 3. An adjusting bolt 5 is rotatably connected inside the upper clamping plate 3. A baffle 6 is fixedly connected to the surface of the adjusting bolt 5. A turntable 7 is fixedly connected to the top end of the adjusting bolt 5. A threaded sleeve 8 is threadedly connected to the bottom of the adjusting bolt 5. A lower clamping plate 9 is fixedly connected to the bottom of the threaded sleeve 8. A guide hole 10 is opened in the middle of the lower clamping plate 9. Friction protrusions 11 are fixedly connected to the inner walls of both the lower clamping plate 9 and the upper clamping plate 3.

[0023] After the wire is passed through the upper clamp 3 and the lower clamp 9 and the fixing clamp is installed on the terminal block, the turntable 7 is rotated so that the adjusting bolt 5 rotates inside the threaded sleeve 8. The height is kept constant by the baffle 6. The threaded sleeve 8 drives the lower clamp 9 to move up and move closer to the upper clamp 3. The slide rod 4 slides in the guide hole 10. After moving up a certain height, the upper clamp 3 and the lower clamp 9 come into contact with the wire, thereby fixing the position of the wire near the fixing clamp and preventing the fixing clamp from loosening when the wire accidentally touches it. Friction protrusions 11 are provided on both the upper clamp 3 and the lower clamp 9 to increase the friction between the wire and the wire and improve the stability after fixing.

[0024] The connecting plate 2 adopts an L-shaped structure. The upper clamping plate 3 and the lower clamping plate 9 are each provided with six arc-shaped grooves on the side that are close to each other. The friction protrusion 11 is located inside the arc-shaped groove, and the slide rod 4 is located inside the guide hole 10.

[0025] The top of the connecting plate 2 is provided with a mounting groove 12, and a support plate 13 is provided inside the mounting groove 12. The top of the support plate 13 is threaded with a fastening bolt 14.

[0026] The fastening bolt 14 and the support plate 13 form a bolt-type terminal block, thereby changing its height by rotating the fastening bolt 14 to facilitate the installation and removal of the fixing clip, and providing a reliable and stable connection through the fit of the fastening bolt 14 and the threaded groove.

[0027] There are six mounting slots 12, and the number of support plates 13 corresponds to the number of mounting slots 12. The top of the support plate 13 is provided with a threaded groove.

[0028] A connecting frame 15 is fixedly connected to the top of the connecting plate 2. Mounting blocks 16 are fixedly connected to the left and right sides of the connecting frame 15. A sliding groove 17 is provided in the middle of the mounting block 16. A return spring 18 is fixedly connected to the inner wall of the sliding groove 17. A limit block 19 is slidably connected inside the sliding groove 17. A pressing plate 20 is provided on the side of the limit block 19 away from the return spring 18. A slot 21 is provided at the top of the mounting block 16. A hook block 22 is provided inside the slot 21. A dust cover 23 is fixedly connected to the top of the hook block 22.

[0029] By aligning the hook block 22 with the slot 21, pressing down on the dust cover 23 causes the hook block 22 to slide within the slot 21. After sliding down a certain height, the hook block 22 contacts the limiting block 19, and relative sliding occurs through the contacting slope. The limiting block 19 slides within the slide groove 17, and the return spring 18 is compressed and contracted. When the dust cover 23 contacts the mounting block 16, the hook block 22 engages with the limiting block 19, thus fixing the position of the dust cover 23. Pressing the pressing plate 20 inward causes the limiting block 19 to slide within the slide groove 17 and separate from the hook block 22. Pulling up on the dust cover 23 allows it to be disassembled, improving the ease of installation and disassembly. Furthermore, by setting the dust cover 23, contact between dust and foreign objects and the wiring terminals can be reduced, thereby reducing the frequency of cleaning.

[0030] The reset spring 18 and the limit block 19 are fixedly connected. The limit block 19 and the hook block 22 are engaged. The pressing plate 20 is located inside the slide groove 17. The dust cover 23 is in contact with the connecting frame 15.

[0031] Mounting bases 24 are provided on the front and rear sides of the small transformer body 1. Connecting bolts 25 are provided between the mounting bases 24 and the small transformer body 1. Nuts 26 are threaded onto the surface of the connecting bolts 25.

[0032] This utility model provides a wiring and fixing structure for a small transformer, and its specific working principle is as follows:

[0033] In use, the mounting base 24 and the small transformer body 1 are fixed to the workplace using screws. The wire is routed around the bottom of the lower clamp 9 and passed between the upper clamp 3 and the lower clamp 9. The fixing clip at one end of the wire is installed on the terminal block. The screwdriver is used to rotate the fastening bolt 14 and fix the position of the fixing clip with the support plate 13. The turntable 7 is rotated so that the adjusting bolt 5 rotates inside the threaded sleeve 8. The baffle 6 limits its height. The threaded sleeve 8 drives the lower clamp 9 to move upward and move closer to the upper clamp 3. The sliding rod 4 slides in the guide hole 10. After moving upward to a certain height... After the angle is adjusted, the upper clamp 3 and the lower clamp 9 come into contact with the wire, thereby fixing the position of the wire near the fixing clamp. The hook block 22 is aligned with the slot 21, and the dust cover 23 is pressed down, causing the hook block 22 to slide in the slot 21. After moving down a certain height, the hook block 22 comes into contact with the limiting block 19 and slides relative to each other through the contacting slope. The limiting block 19 slides in the slide groove 17, and the return spring 18 is compressed and contracted. When the dust cover 23 comes into contact with the mounting block 16, the hook block 22 and the limiting block 19 engage, thereby fixing the position of the dust cover 23 to achieve dust prevention at the terminal block.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
