The inner side of the internal threaded tube 6 is connected to the connecting threaded rod 7. The snap-fit ​​block 4 and the sliding snap-fit ​​block 5 are adapted to snap-fit, which can limit the installation position. Then, by rotating the connecting threaded rod 7, the connecting threaded rod 7 extends upward inside the internal threaded tube 6 and forms a connection with the bottom connecting seat 8 of the other controller body 1 to achieve the effect of fixation.

[0027] Specifically, such as Figure 3 As shown, the sliding block 5 is fixedly connected to the bottom of the controller body 1, and a connecting seat 8 is connected to one side of the sliding block 5. The connecting seat 8 has a thread inside, and the connecting seat 8 and the connecting threaded rod 7 can be threadedly connected and fixed.

[0028] Specifically, such as Figure 2 As shown, a rotating rod 9 is connected to the inner side of the heat sink 3, and a docking rod 10 is connected to the outer side of the rotating rod 9. A magnetic block 11 is connected to the outer side of the docking rod 10. The rotating rod 9 can slide up and down and rotate on the inner side of the heat sink 3. When the two controller bodies 1 are connected, they are connected to each other through the docking rod 10, which can further improve the heat dissipation range, allow temperature exchange, and make the heat dissipation effect more stable.

[0029] The outer side of the controller body 1 is provided with a plug-in fixing component, which includes a plug-in block 13. A positioning clamp 17 is provided on one side of the plug-in block 13, and an elastic connecting rod 18 is provided on the inner side of the positioning clamp 17. The plug-in fixing component is used for left and right position connection of the controller body 1.

[0030] Specifically, such as Figure 4 As shown, one end of the controller body 1 is connected to a fixing plate 12, and a plug-in block 13 is disposed on the outside of the fixing plate 12. The plug-in block 13 has a fixing groove inside, which is in the same position as the groove of the positioning clamp block 17.

[0031] Specifically, such as Figure 4 As shown, a prepositioning block 14 is connected to the outside of the plug-in block 13, and four prepositioning blocks 14 are provided. The four prepositioning blocks 14 can preliminarily lock the position of the plug-in block 13 to a certain extent.

[0032] Specifically, such as Figure 4 As shown, one end of the controller body 1 is connected to a fixing plate 2 15, and one end of the fixing plate 2 15 is connected to a guide slider 16. The positioning clamp 17 is located on the outside of the guide slider 16. The positioning clamp 17 slides on the outside of the fixing plate 2 15 and the range is controlled by the guide slider 16.

The pre-positioning groove 20 is adapted to the pre-positioning block 14 and can be snapped and fixed.

[0034] In this embodiment: when connecting multiple controllers, they can be installed by stacking. The sliding engagement of the locking block 4 and the sliding block 5 in the middle limits the spacing. The inner side of the rear heat sink 3 is connected to each other by the docking rod 10 to form a heat dissipation adjustment, which improves the stability of the instrument installation, allows the instrument to be modularly distributed, and facilitates maintenance. On both sides of the controller body 1, the insertion of the plug-in block 13 and the two positioning clamps 17 can also form a positioning. The middle of the positioning clamps 17 can be elastically connected, and the connection and fixation are performed after clamping and limiting.

[0035] The specific solution is as follows: During the use of PWM controllers, high-power systems require multiple PWM controllers to be used in parallel. To ensure that multiple controllers do not interfere with each other after connection and to ensure the stability of the connection, the controller body 1 can be modularly connected and fixed by stacking. The sliding block 5 is locked in the locking block 4 of another controller body 1, and then the connecting threaded rod 7 is rotated to screw the connecting threaded rod 7 upward into the connecting seat 8 to achieve the fixing effect. The heat sink 3 at the rear end has increased the heat dissipation area to a certain extent. The heat dissipation parts of the two controller bodies 1 are connected by the rotatable connecting rod 10 to improve the temperature exchange efficiency and facilitate the uniformity of heat dissipation. When connecting multiple controller bodies 1, the outside can also be inserted into the inside of the two positioning clamps 17 through the plug-in block 13. At this time, the pre-positioning block 14 is locked in the inside of the pre-positioning slot 20 for pre-positioning. The positioning clamp 17 can be elastically clamped under the connection of the elastic connecting rod 18 to achieve the pre-positioning effect. Finally, the plug-in block 13 and the positioning clamp 17 are fixed by screw connection to ensure the stability of the circuit after the controller bodies 1 are connected in parallel.
