[0002] In the field of power supplies, aging tests are required before power supplies leave the factory. The existing test usually involves directly powering on the power supply with a load for aging. If the power supply works continuously for a period of time without failure and all parameters are stable, it is considered a qualified product.

[0003] An existing power supply aging test device (publication number: CN215728703U) has at least the following disadvantages: the device connects a power supply to a power supply test module, and cooperates with the mutual connection of the power supply test modules at each level, so that the power supply at the upper level can provide power to the power supply at the lower level for testing. However, if a power supply fails during the test, the subsequent power supplies of the power supply will no longer be able to receive power for testing, resulting in the need for staff to disassemble the power supply and reconnect a new power supply. In addition, the connection of the power supply requires manual docking, and the docking speed is slow, thereby affecting the test efficiency. For this reason, the present utility model is proposed.

[0022] like Figure 1-Figure 4 As shown, a power module aging test device includes a base 1, and a test assembly is provided on the top surface of the base 1.

A junction box is fixed inside the test box 2, and the junction box is electrically connected to the electronic load meter. An insulating plate 201 is provided on the bottom surface of the inner part of the test box 2, and a plurality of copper rods 202 are passed through and fixedly inserted on the top surface of the insulating plate 201. The output line of the junction box is connected to the top of the copper rod 202, and a plurality of lifting plates 203 are provided on the top surface of the base 1.

[0023] like Figure 2-Figure 4As shown, in this embodiment, a support frame 204 is fixed to the top surface of the base 1, and a plurality of threaded rods 205 are threadedly connected to the top surface of the support frame 204. A square hole 210 is opened on the top surface of the threaded rod 205, and the threaded rod 205 is rotatably connected to the bottom surface of the lifting plate 203. A rodless cylinder 206 is also fixed to the top surface of the slider of the rodless cylinder 206. An electric push rod 207 is fixed to the top surface of the slider of the rodless cylinder 206. A drive motor 208 is fixed to one end of the telescopic rod of the electric push rod 207, and a square rod 209 is fixed to one end of the output shaft of the drive motor 208. By setting up a multi-channel electronic load meter, a junction box and a copper rod 202, multiple power supplies can be tested simultaneously, and the copper rod 202 can be automatically plugged into the power interface end during testing, without the need for manual docking, thereby increasing work efficiency. When a power supply fault is detected, the connection between the power supply and the copper rod 202 can be automatically disconnected without affecting the normal testing of other power supplies. At the same time, the faulty power supply can be removed and replaced with a new power supply for testing, thereby ensuring test efficiency.

[0024] like Figure 2-Figure 4 When the cam 303 is unlocked, the cam 303 is unlocked, and the cam 303 is unlocked, so that the cam 303 can be unlocked.

[0025] like Figure 2-Figure 4 As shown, in this embodiment, limiting rods 4 are fixed at the four corners of the bottom surface of the lifting plate 203, and the limiting rods 4 and the top surface of the support frame 204 are slidably inserted. By slidably inserting the limiting rods 4 and the top surface of the support frame 204, the lifting and lowering of the lifting plate 203 is limited, making the lifting and lowering of the lifting plate 203 more stable.

[0026] like Figure 2-Figure 4As shown, in this embodiment, the insulating plate 201 is an acrylic plate, and the insulating plate 201 is detachably mounted on the inner bottom surface of the test box 2 by bolts, and the output line of the junction box is fixed to the top of the copper rod 202 by nuts. By setting the insulating plate 201 to be detachably mounted on the inner bottom surface of the test box 2 by bolts, the output line of the junction box is fixed to the top of the copper rod 202 by nuts, so that the insulating plate 201 and the copper rod 202 can be disassembled and replaced, and different insulating plates 201 and copper rods 202 can be replaced when different types of power supplies need to be tested, and the PLC controller is electrically connected to the rodless cylinder 206, the electric push rod 207, the drive motor 208 and the multi-channel electronic load meter respectively.

[0027] like Figure 2-Figure 4 As shown, in this embodiment, the front side of the test box 2 is connected to a protective door 5 by a hinge, and the left and right sides of the protective door 5 are locked with the test box 2 by buckles. The protective door 5 can protect the copper rod 202 and the junction box inside the test box 2.

[0028] From the above description, it can be seen that the above embodiment of the present invention achieves the following technical effects: in use, the power supply to be tested is placed on the top surface of the lifting plate 203, and the two clamping plates 303 are pulled away from the power supply respectively. At this time, the clamping plates 303 slide on the rebound rod 302 and compress the spring. At this time, the rear side and the right side of the power supply are respectively fitted with the two fixed plates 3, and then the clamping plates 303 are released and the spring rebounds. The two clamping plates 303 are respectively fitted with the front side and the left side of the power supply, thereby achieving the clamping of the power supply. The rod 209 is held in position, and then the rodless cylinder 206 is started to drive the square rod 209 to move to the bottom of the threaded rod 205. The electric push rod 207 is then started to insert the square rod 209 into the inside of the square hole 210. The drive motor 208 is then started to drive the square rod 209 to rotate, so that the threaded rod 205 rotates. Under the action of the threaded connection between the threaded rod 205 and the support frame 204, the lifting plate 203 is lifted, so that the copper rod 202 is inserted into the interface end of the power supply. Then the electric push rod 207 is reset, and the rodless cylinder 206 moves the square rod 209 to the bottom. A lifting plate 203 is lifted, and after all power supplies are connected, the multi-channel electronic load meter is started for testing. When a power supply fails during the test, the multi-channel electronic load meter sends an electrical signal to the PLC controller, and the PLC controller controls the rodless cylinder 206, the electric push rod 207 and the drive motor 208 to separate the test power supply from the copper rod 202. At this time, the staff can replace the new power supply to continue the test work. The lifting plate is slidably inserted into the top surface of the limit rod 4 and the support frame 204, thereby The lifting and lowering of 203 plays a limiting role, making the lifting and lowering of the lifting plate 203 more stable. By setting the insulating plate 201 to be detachably installed with bolts and the inner bottom surface of the test box 2, the output line of the junction box and the top of the copper rod 202 are tightened and fixed by nuts, so that the insulating plate 201 and the copper rod 202 can be disassembled and replaced. Different insulating plates 201 and copper rods 202 can be replaced when different models of power supplies need to be tested. The copper rod 202 inside the test box 2 and the junction box can be protected through the protective door 5.
