[0002] A power module is a combination of power electronic devices, packaged together according to specific functions. It consists of high-speed, low-power transistors (IGBTs), optimized gate drive circuits, and fast protection circuits. The IPMs are all high-speed IGBTs, and the drive circuits are located close to the IGBs, minimizing drive delays. This results in fast switching speeds and minimal losses.

[0003] The power module is a common module in power distribution equipment. After production, the power module needs to be debugged. During the debugging process, the staff needs to connect the wiring of the detection and debugging equipment with the wiring part of the power module. The current conventional wiring method is basically to insert the wiring of the detection and debugging equipment into the wiring part of the power module, and then use bolts to tighten the wiring to ensure the connection. However, the wiring is usually composed of multiple strands of wire. During the tightening process, the bolts are likely to loosen the wiring, resulting in poor contact of the wiring. Moreover, after the power module is connected and fixed during normal use, the wiring is easily broken after being loosened over a long period of use, affecting the normal use of the power module. For this reason, we propose a power module that is easy to debug. Utility Model Content

[0018] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a power module that is easy to debug, including a module body 1 and a wiring port 2 arranged on the module body 1, the wiring port 2 is provided with a fastening bolt 5 for fastening the wiring, the inner side and back of the wiring port 2 are provided with a driven part 3 for tightening the wiring, and the inner side of the wiring port 2 is provided with a locking component 4 for limiting the driven part 3.

[0019] The driven part 3 includes an auxiliary disk 31, which is rotatably mounted on the inner side of the wiring port 2. A rubber protrusion 32 is fixed to the surface of the auxiliary disk 31, and a resisting spring 33 is fixed to the inner side of the wiring port 2. An active disk 34 is rotatably mounted on the front of the auxiliary disk 31. A control rod 35 is fixed to the back of the active disk 34. The control rod 35 passes through the auxiliary disk 31 and the wiring port 2. A spiral spring 36 is fixed to the surface of the control rod 35. The end of the spiral spring 36 away from the control rod 35 is fixed to the wiring port 2. A guide groove 37 is provided on the front of the auxiliary disk 31, and an arc groove 38 is provided on the active disk 34. A tightening rod 39 is slidably installed on the inner side of the guide groove 37. The tightening rod 39 passes through the arc groove 38. The resisting spring 33 can resist the rubber protrusion 32 on the surface of the auxiliary disk 31 under its own elastic action, increasing the friction between the auxiliary disk 31 and the auxiliary disk 31, so that the auxiliary disk 31 can rotate only when it is subjected to a certain degree of external force. When the active disk 34 is no longer restricted, the spiral spring 36 can rotate the auxiliary disk 31. When the cam 35 is in the closed position, the cam 35 is in the closed position, and the cam 35 is in the closed position, so that the cam 35 is in the closed position, and the cam 35 is in the closed position, so that the cam 35 is in the closed position, and the cam 35 is in the closed position, so that the cam 35 is in the closed position, and the cam 35 is in the closed position, so that the cam 35 is in the closed position, and the cam 35 is in the closed position, so that the cam 35 is in the closed position, and the cam 35 is in the closed position, so that the cam 35 is in the closed position,

[0020] There are four groups of interference spring pieces 33, and the four groups of interference spring pieces 33 are arranged in a circular array with the center point of the auxiliary disk 31 as the center of the circle. The four groups of interference spring pieces 33 can better contact the auxiliary disk 31, increase the friction between the auxiliary disk 31 and the auxiliary disk 31, and limit the auxiliary disk 31 to a certain extent to prevent the auxiliary disk 31 from rotating when the active disk 34 just starts to rotate, causing the tightening rod 39 to be unable to move normally. There are three groups of guide grooves 37, arc grooves 38 and tightening rods 39. The three groups of guide grooves 37, arc grooves 38 and tightening rods 39 are arranged in a circular array on the auxiliary disk 31 and the active disk 34. Through the three groups of tightening rods 39, the wiring inserted into the wiring port 2 can be better held and tightened.

[0021] The locking assembly 4 includes a bracket 41, the top of which is fixed to the inner side of the wiring port 2, and a locking rod 42 is hinged on the inner side of the bracket 41. A reset spring 43 is fixed on the top of the locking rod 42, and the end of the reset spring 43 away from the locking rod 42 is fixed to the back of the bracket 41. The surface of the active disk 34 is provided with an annular locking tooth 44, and the locking rod 42 can be inserted into the annular locking tooth 44 on the surface of the active disk 34 to limit the active disk 34, so that the active disk 34 cannot rotate. When the fastening bolt 5 is screwed into the wiring port 2 from the top of the wiring port 2, the fastening bolt 5 can abut against the locking rod 42, so that the locking rod 42 rotates at the position hinged to the bracket 41, and the locking rod 42 is no longer stuck in the annular locking tooth 44 on the surface of the active disk 34, thereby releasing the limit on the active disk 34.

[0022] When debugging the module body 1, the wiring of the detection instrument is inserted into the wiring port 2 of the module body 1, and the fastening bolt 5 is screwed into the wiring port 2 from the top of the wiring port 2 by using a screwdriver. At this time, the fastening bolt 5 abuts against the clamping rod 42, so that the clamping rod 42 rotates at the position hinged to the bracket 41, and the clamping rod 42 no longer gets stuck in the annular clamping tooth 44 on the surface of the active disk 34, thereby releasing the limit on the active disk 34.

[0023] When the active disk 34 is no longer restricted, under the action of the spiral spring 36, the control rod 35 drives the active disk 34 to rotate. Since the tightening rod 39 is restricted by the guide groove 37, the tightening rod 39 can only move along the guide groove 37. The active disk 34 can only contact the tightening rod 39 through the arc groove 38 opened by itself, so that it slides along the guide groove 37 to the side close to the center of the auxiliary disk 31. The tightening rod 39 can hold the wire inserted into the wiring port 2. When the tightening rod 39 can no longer move and the active disk 34 continues to rotate, the active disk 34 The dynamic disk 34 can apply a rotational force to the auxiliary disk 31 through the tightening rod 39. At this time, the auxiliary disk 31 can only rotate by overcoming the resistance of the resistance spring 33. The tightening rod 39 rotates together with the wiring, thereby tightening the wiring, so that the wiring can be better fixed by the fastening bolt 5, avoiding the wiring from being loose due to resistance, resulting in unstable contact, making it more convenient for staff to debug the module body 1, and avoiding the phenomenon of wiring being broken due to looseness after normal long-term use, which affects the normal use of the module body 1.

[0024] After debugging is completed, loosen the fastening bolt 5, but do not remove the fastening bolt 5 completely. At this time, just hold the control lever 35 and turn the control lever 35. The control lever 35 drives the active disk 34 to rotate, and controls the tightening rod 39 to reset and loosen the fixation of the docking line. During this process, the control lever 35 rewinds the volute spring 36 to store force. After the wiring is pulled out, the fastening bolt 5 is taken out, and the clamping rod 42 is no longer resisted by the fastening bolt 5. Under the action of the reset spring 43, the clamping rod 42 rotates and resets to the position hinged to the bracket 41, and the clamping rod 42 is re-engaged in the annular clamping tooth 44 to limit the active disk 34, completing the reset of the device.

[0025] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
