Description

Technical Field

[0001] The utility model relates to the technical field of electrical products, and more specifically, particularly to a temperature rise testing device for electrical products. Background Art

[0002] Before electrical products are put on the market, they need to undergo a series of physical tests. The temperature rise test is an important test to evaluate whether the heat generated by electronic and electrical equipment under normal working conditions will cause its key components to overheat, thereby affecting product performance, reliability and safety. At present, the temperature rise test device fixes high-efficiency electrical products during testing, but cannot adjust the size. It clamps and fixes high-efficiency electrical products of different sizes, which makes it limited. When testing the temperature rise of high-efficiency electrical products, it can only test one temperature value, and the test is not accurate enough.

[0003] Regarding the temperature rise test device for electrical products, it was found through search that the application number CN202122308555.0 discloses a temperature rise test device for high-efficiency electrical products. This temperature rise test device places the high-efficiency electrical product in a limit groove, twists the threaded rod, and makes the first push plate push the high-efficiency electrical product toward the test component, so that the high-efficiency electrical product is against the other end of the limit groove, and then rotates the connecting rod to turn the threaded tube out of the threaded hole. The spring will bounce the second push plate to the middle position of the limit groove, so that the second push plates on both sides fix the high-efficiency electrical product to prevent it from being tested during the test. The device shakes and affects the test results, but there are still certain defects in actual use. For example, the function of the first push plate is to push the electronic product toward the test component, but this effect can also be achieved by pushing it by hand. At the same time, the device needs to rotate the two connecting rods on both sides to move the two second push plates to the middle and fix the electronic product. However, it is troublesome to rotate the two connecting rods, and the efficiency is low when facing a large number of temperature rise tests. In addition, the temperature sensor of the device is fixed and cannot detect the temperature rise of different positions of the electronic product, resulting in incomplete detection data.

[0026] The implementation of the utility model is further described in detail below in conjunction with the drawings and examples.

[0027] Example:

[0028] As attached Figure 1 To Attachment Figure 8 As shown:

[0029] The utility model provides a temperature rise test device for an electrical product, comprising a workbench 1; a placement groove 101 is provided inside the workbench 1, a bottom plate 102 is provided at the bottom of the placement groove 101, an equipment platform 2 is provided at one side of the workbench 1, a battery is installed inside the equipment platform 2, a display 201 is provided at the top of the equipment platform 2, an adjustment knob and a control button are respectively provided at the top of the equipment platform 2, a connecting line 103 is provided at one side of the placement groove 101, a temperature sensor 3 is provided at one side of the top of the placement groove 101, clamping components are provided at both sides of the placement groove 101, and a moving component is provided at one side of the top of the workbench 1.

[0030] Among them, the clamping assembly includes: a bottom groove 4, a hand crank 401, an external thread 402, a clamping plate 403, a movable plate 404 and a threaded hole a405. A bottom groove 4 is opened at the bottom of the placement groove 101, and a hand crank 401 is provided on one side of the bottom of the workbench 1 to penetrate into the bottom groove 4. The hand crank 401 is rotatably connected to the inner wall of the bottom groove 4 through a bearing. Two opposite external threads 402 are respectively provided on both sides of the outer surface of the hand crank 401. Clamping plates 403 are provided on both sides of the placement groove 101. A movable plate 404 is connected to the bottom of the clamping plate 403. A threaded hole a405 is opened at the bottom of the movable plate 404, and the threaded hole a405 is threadedly connected to the external thread 402.

[0031] When performing a temperature rise test on an electronic product, the electronic product is placed in the placement slot 101, and the connecting line 103 is connected to the electronic product. Then, the hand crank 401 is rotated to make it rotate inside the bottom slot 4. The two movable plates 404 are threadedly connected to the two opposite external threads 402 set on both sides of the outer surface of the hand crank 401 due to the threaded holes a405 opened at the bottom. At this time, the two movable plates 404 can drive the clamping plates 403 to move toward the middle and clamp the electronic product to prevent it from shaking during the test and to avoid the disconnection of the connecting line 103 from the electronic product during the test. The two clamping plates 403 only need to be rotated unilaterally to clamp the electronic product, which can reduce the time of clamping the electronic product and improve the test efficiency.

[0032] Among them, the bottom of the movable plate 404 extends to the inside of the bottom groove 4, and the movable plate 404 is consistent in width with the bottom groove 4. Since the movable plate 404 is consistent in width with the bottom groove 4, when the hand crank 401 is rotated to make the external thread 402 rotate inside the threaded hole a405, the movable plate 404 is restricted by the bottom groove 4, so that it cannot rotate, thereby enabling it to move laterally.

[0033] Among them, openings 104 are opened on both sides of the bottom plate 102, and the two openings 104 correspond to the positions of the bottom groove 4. The movable plate 404 passes through the openings 104. When the movable plate 404 drives the clamping plate 403 to move, the openings 104 corresponding to the positions of the bottom groove 4 are opened on both sides of the bottom plate 102, so that the bottom plate 102 can be used normally.

[0034] Among them, the moving component includes: a slot 5, a moving block 501, a mounting plate 502 and a threaded rocker 503. A slot 5 is opened on one side of the upper surface of the workbench 1, and the moving block 501 is slidably connected inside the slot 5. A mounting plate 502 is provided on the top of the moving block 501, and the temperature sensor 3 is installed on the bottom side of the mounting plate 502. A threaded rocker 503 extending into the slot 5 is provided on one side of the outer end of the workbench 1, and the threaded rocker 503 is rotatably connected to one side of the inner wall of the slot 5 through a bearing. A threaded hole b504 is opened inside the moving block 501, and the threaded hole b504 is threadedly connected to the threaded rocker 503.

[0035] After the electronic product to be tested is clamped and fixed, the battery is controlled by the control button to supply power to the electronic product through the connecting line 103. At this time, the temperature sensor 3 installed at the bottom of the mounting plate 502 will detect the temperature of the electronic product and transmit the detection data to the display 201 through an electrical signal. The current output power of the battery to the electronic product can be adjusted by adjusting the knob to observe the temperature rise state of the electronic product. After performing the above operation, the threaded rocker 503 is rotated to rotate inside the slot 5. At this time, the threaded rocker 503 rotates in the threaded hole b504 opened inside the moving block 501, and the moving block 501 is slidably connected to the inside of the slot 5, and the threaded hole b504 is threadedly connected to the threaded rocker 503, so that the moving block 501 can translate inside the slot 5, and the moving block 501 drives the mounting plate 502, thereby moving the temperature sensor 3 above the electronic product to detect the temperature rise of different positions of the electronic product, which can make the test data more comprehensive.

[0036] The control program involved in the present utility model can be implemented by those skilled in the art according to the same or similar principles in the prior art, and this part is not the innovation of the present utility model.

[0037] Among them, a bottom block 505 is provided on the top of the moving block 501, and a circular hole 506 is opened on the top of the bottom block 505. A rotating rod 507 is rotatably connected inside the circular hole 506, and the rotating rod 507 is fixedly connected to the mounting plate 502. After the temperature rise test of the electronic product is completed, the mounting plate 502 is rotatably connected to the circular hole 506 opened on the top of the bottom block 505 through the rotating rod 507 fixedly connected at the bottom, so that the mounting plate 501 can be rotated to the top of the slot 5 by moving it, so that the electronic product inside the placement slot 101 can be taken out, which can prevent the mounting plate 501 from hindering the electronic product from being placed in the placement slot 101 or taken out of the placement slot 101.

[0038] The specific usage and function of this embodiment are as follows:

[0039] When performing a temperature rise test on an electronic product, the electronic product is placed in the placement slot 101, and the connecting line 103 is connected to the electronic product. Then, the hand crank 401 is rotated to make it rotate inside the bottom slot 4. The two movable plates 404 are threadedly connected to the two opposite external threads 402 set on both sides of the outer surface of the hand crank 401 due to the threaded holes a405 opened at the bottom. At this time, the two movable plates 404 can drive the clamping plates 403 to move toward the middle and clamp the electronic product to prevent it from shaking during the test and to avoid the disconnection of the connecting line 103 from the electronic product during the test. The two clamping plates 403 only need to be rotated unilaterally to clamp the electronic product, which can reduce the time of clamping the electronic product and improve the test efficiency.

[0040] After the electronic product to be tested is clamped and fixed, the battery is controlled by the control button to supply power to the electronic product through the connecting line 103. At this time, the temperature sensor 3 installed at the bottom of the mounting plate 502 will detect the temperature of the electronic product and transmit the detection data to the display 201 through an electrical signal. The current output power of the battery to the electronic product can be adjusted by adjusting the knob to observe the temperature rise state of the electronic product. After performing the above operation, the threaded rocker 503 is rotated to rotate inside the slot 5. At this time, the threaded rocker 503 rotates in the threaded hole b504 opened inside the moving block 501, and the moving block 501 is slidably connected to the inside of the slot 5, and the threaded hole b504 is threadedly connected to the threaded rocker 503, so that the moving block 501 can translate inside the slot 5, and the moving block 501 drives the mounting plate 502, thereby moving the temperature sensor 3 above the electronic product to detect the temperature rise of different positions of the electronic product, which can make the test data more comprehensive.
