The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] The utility model embodiment provides a rectifier transformer lead structure, such as Figure 1-3As shown, the lead structure of the rectifier transformer includes: a transformer body 1 provided with a plurality of terminals 2; two arranging frames 3, both of which are fixedly mounted on the transformer body 1 and arranged corresponding to the terminals 2; two screws 4, both of which are rotatably mounted on the two arranging frames 3; two pressing plates 5, both of which are arranged on the two arranging frames 3, and both of which are threadedly connected to the two screws 4; a partition column 6, with a plurality of partition columns 5, each of which is fixedly mounted on the arranging frames 3 and slides through the pressing plate 5, and the partition column 5 is arranged corresponding to the terminals 2; and two clamping and fixing mechanisms, both of which are arranged on the two screws 4 for driving the pressing plate 5 to move to fix the lead.

[0021] In this embodiment, the terminal 2 provided on the transformer body 1 is a key component for connecting the transformer to the external circuit, and is used to receive and output current. The main function of the arranging frame 3 is to provide a fixed support structure for subsequent lead arrangement. The rotation function of the screw 4 enables the subsequent pressing plate 5 to move, thereby achieving the compression and fixation of the lead. The main function of the pressing plate 5 is to compress the lead under the drive of the screw 4, so that it is fixed on the arranging frame 3 to prevent it from moving or winding. A plurality of partition columns 6 are respectively fixedly mounted on the two arranging frames 3, and slide through the pressing plate 5 at the same time. The partition column 6 is arranged corresponding to the terminal 2, and its function is to further fix the lead to prevent it from moving or dislocating under the pressing plate 5, and at the same time separate the multiple leads connected to the terminal 2, so as to facilitate subsequent maintenance and arrangement. The two clamping and fixing mechanisms in the structure are respectively arranged on the two screws 4, and their function is to drive the pressing plate 5 to move to fix the lead. The clamping and fixing mechanism can ensure the fixing effect of the lead, so that it remains stable during use and is not easy to loosen.

[0022] In a further preferred embodiment of the utility model, the clamping and fixing mechanism includes a slider 7, an operating block 8, a slide groove 9 and a positioning mechanism. There are multiple sliders 7, and the sliders 7 are fixedly mounted on the screw rod 4. The operating block 8 is sleeved on the screw rod 4. The slide groove 9 is opened on the operating block 8 and is arranged corresponding to the slider 7. The positioning mechanism is arranged on the operating block 8 for fixing the operating block 8, and the positioning mechanism is arranged corresponding to the sorting rack 3.

[0023] In this embodiment, there are multiple sliders 7, which are fixedly mounted on the screw rod 4. The operating block 8 is sleeved on the screw rod 4 and can fit with the slider 7 to limit the operating block 8. The slide groove 9 provided on the operating block 8 is arranged corresponding to the slider 7. When the operating block 8 moves along the screw rod, the slide groove 9 interacts with the slider 7, so that the operating block 8 can drive the screw rod 4 to rotate. The positioning mechanism is arranged on the operating block 8, and its main function is to fix the position of the operating block 8. When the operating block 8 rotates to drive the pressure plate 5 to fix the lead, the positioning mechanism can lock it to prevent it from rotating. The positioning mechanism is arranged corresponding to the sorting frame 3, and the operating block 8 will form a stable connection with the sorting frame 3, thereby ensuring the stability of the entire clamping and fixing mechanism.

[0024] In a further preferred embodiment of the utility model, the positioning mechanism includes a limit block 10, a positioning groove 11 and a resistance pad 12, there are multiple limit blocks 10, and the limit block 10 is fixedly installed on the operating block 8. The sorting rack 3 is provided with a positioning groove 11, there are multiple positioning grooves 11 and they are arranged corresponding to the limit block 10, and the resistance pad 12 is fixedly installed in the positioning groove 11, and there are multiple resistance pads 12.

[0025] In this embodiment, the limit block 10 plays a role in limiting the movement of the operating block 8, ensuring that the operating block 8 can remain stable after being pressed down. When the pressure plate 5 moves downward to the position where the lead clamp is fixed, the operating block 8 is pressed downward to make the limit block 10 embedded in the corresponding positioning groove 11, thereby fixing the operating block 8 and preventing the operating block 8 from rotating. In order to enhance the stability of positioning and prevent the operating block 8 from loosening after being fixed, a resistance pad 12 is also fixedly installed in the positioning groove 11. The resistance pad 12 is made of a material with a certain friction force. When the limit block 10 is embedded in the positioning groove 11 and contacts the resistance pad 12, a certain friction force will be generated, thereby preventing the operating block 8 from moving when subjected to external force.

[0026] In a further preferred embodiment of the utility model, a guide mechanism is provided on the transformer body 1 for guiding and limiting the lead wire, and the guide mechanism includes a fixed shaft 13, two guide blocks 14, a fixing frame 15 and a sealing ring 16.

The fixing frame 15 is sleeved on the fixed shaft 13 and conflicts with the guide block 14. The sealing ring 16 is threadedly mounted on the fixed shaft 13, and the sealing ring 16 conflicts with the fixing frame 15.

[0027] In this embodiment, the fixed shaft 13 is stably mounted on the transformer body 1, playing a supporting and fixing role, and the two guide blocks 14 are fixedly mounted on the transformer body 1 and arranged corresponding to the terminal 2. The design of these guide blocks 14 enables the lead wire to be connected according to a predetermined path, avoiding the deviation and misalignment of the lead wire. The fixed frame 15 is sleeved on the fixed shaft 13 and conflicts with the guide block 14. The fixed frame 15 and the guide block 14 form a clamping state, which can better fix the lead wire and separate the lead wires connected to each terminal 2. The sealing ring 16 is installed on the fixed shaft 13 by threading. The main function of this component is to provide a sealing effect, prevent dust, moisture and other external impurities from entering the place where the fixed shaft 13 is connected to the fixed frame 15 and releasing the terminal 2, and ensure the safe connection of the lead wire. At the same time, the sealing ring 16 conflicts with the fixed frame 15 and also plays a certain fixing role.

[0028] In a further preferred embodiment of the present invention, arc grooves are provided on the two guide blocks 14 and the fixing frame 15, and a plurality of the arc grooves are provided corresponding to the lead wires.

[0029] In this embodiment, the provision of the arc groove enables the lead wire to move more smoothly and naturally along a predetermined path when passing through the guide mechanism. This design not only reduces the risk of friction and damage to the lead wire during the connection process, but also improves the stability and reliability of the connection. The provision of the arc groove also further enhances the guiding and limiting functions of the guide mechanism. By reasonably designing the shape and size of the arc groove, it can be ensured that the lead wire always remains in the correct position when passing through the guide mechanism, avoiding the deviation and misalignment of the lead wire.

[0030] In a further preferred embodiment of the utility model, two positioning blocks 17 are fixedly installed on the fixing frame 15, and a shielding frame 18 is provided on the fixing frame 15. The shielding frame 18 is arranged corresponding to the two positioning blocks 17, and a fixing bolt 19 is threadedly installed on the shielding frame 18, and the fixing bolt 19 is threadedly connected to the fixed shaft 13.

[0031] In this embodiment, the provision of the positioning block 17 makes the connection between the shielding frame 18 and the fixing frame 15 more stable, while improving the convenience of installation, and enhancing the stability and reliability of the connection. The main function of the shielding frame 18 is to provide additional support and protection to prevent external objects or impurities from interfering with or damaging the fixing frame 15. This design helps to improve the overall stability and service life of the guide mechanism. In order to further fix the position of the shielding frame 18, a fixing bolt 19 is also threadedly installed on the shielding frame 18. The fixing bolt 19 is threadedly connected to the fixed shaft 13. By tightening the fixing bolt, the shielding frame 18 can be firmly fixed to the fixed shaft 13 to prevent it from loosening or shifting during use.

[0032] In a further preferred embodiment of the present invention, two separation pads 20 are fixedly mounted on the transformer body 1 , and the two separation pads 20 are respectively arranged corresponding to the two arranging racks 3 and the two pressing plates 5 .

[0033] In this embodiment, two separation pads 20 are respectively arranged corresponding to the two arranging frames 3 and the two pressing plates 5. Through the arrangement of the separation pads 20, the fixing of the pressing plate 5 to the lead wire can maintain a stable position and state, and is not prone to displacement or deformation. The introduction of the separation pads 20 also plays a role in protecting the transformer body and the lead wire. It can effectively prevent the pressing plate 5 from directly contacting the transformer body 1, avoiding possible friction and damage.

[0034] In summary, compared with the related art, the utility model realizes stable clamping and orderly guiding of the transformer lead through the ingenious design of the clamping and fixing mechanism and the guiding mechanism, thereby significantly improving the safety and use efficiency of the transformer. The clamping and fixing mechanism utilizes the synergistic effect of the slider 7, the operating block 8, the slide groove 9 and the positioning mechanism to ensure that the lead will not loosen or shift during the fixing process; while the guiding mechanism provides a clear connection path for the lead through the cooperation of components such as the fixed shaft 13, the guide block 14, the fixing frame 15 and the sealing ring 16, thereby avoiding confusion and crossing of the lead. In addition, the design of the separator 20 further enhances the stability of the arrangement and the protection of the transformer body 1.
