Description

Technical Field

[0001] This invention relates to a testing technology, and more particularly to a testing device for the mechanical life of a 5G circuit breaker. Background Technology

[0002] With the advent of the 5G era, base station power distribution systems are facing upgrades and replacements. To meet the specific requirements of these systems, manufacturers have specially customized 5G circuit breakers. The main differences between the new 5G circuit breaker and traditional circuit breakers are as follows:

[0003] 1. The installation method of 5G circuit breakers differs from that of traditional circuit breakers. Traditional circuit breakers are installed on the guide rail of the distribution cabinet and energized by connecting wires; while 5G circuit breakers are directly embedded in the energized busbar.

[0004] 2. The operation of 5G circuit breakers differs from that of traditional circuit breakers. Traditional circuit breakers are operated by moving a lever up and down (up for closing, down for opening); while 5G circuit breakers are operated by two methods: pressing (press to close, pull to open) and tossing (up for closing, down for opening). 5G circuit breakers have a closing / opening lock button, which must be pressed down to close the circuit (when the 5G circuit breaker is normally installed in the 5G communication power cabinet, this button is pressed down by the cabinet's mounting plate).

[0005] For the reasons mentioned above, the current traditional circuit breaker mechanical life testing equipment is no longer suitable for the new 5G circuit breaker products.

[0006] Currently, there is no dedicated testing device for the mechanical life of 5G circuit breakers. Most tests are conducted manually by operators using simple devices. This method lacks fixed standards, resulting in inconsistent judgments. Manual operation is inefficient and poses safety hazards. Simple devices are also incompatible with different products and often fail to meet testing requirements. Summary of the Invention

[0007] To address the issue of low efficiency in mechanical life testing of 5G circuit breakers, a testing device for the mechanical life of 5G circuit breakers is proposed. This device can quickly, accurately, and automatically test the mechanical life of 5G circuit breakers of various specifications.

[0008] The technical solution of this invention is as follows: a testing device for the mechanical life of a 5G circuit breaker, comprising a testing base plate, linear guide rails, energized mounting slots, spring-loaded latching mechanisms, positioning holes, and a closing / opening test mechanism; the testing base plate is equipped with two linear guide rails, and the closing / opening test mechanism is mounted on the two linear guide rails. The closing / opening test mechanism is fixed by rotating a knob plug on its upper part into the positioning holes on the testing base plate. The testing base plate has several positioning holes arranged parallel to the linear guide rails. Between the two linear guide rails, along the moving direction of the closing / opening test mechanism, there are several parallel energized mounting slots. A spring-loaded latching mechanism is fixedly installed on the testing base plate directly below each energized mounting slot. After the 5G circuit breaker is embedded in the energized mounting slot, each stage of the 5G circuit breaker is correspondingly latched into the spring-loaded latching mechanism for fixation.

[0009] By adopting the above technical solution, several 5G circuit breakers can be fixedly installed on the test base plate at the same time. The opening and closing test mechanism moves on the linear guide rail, which can test 5G circuit breakers at different positions and perform positioning tests to ensure the accuracy of the test.

[0010] Preferably, the closing / opening test mechanism includes a support plate, a stepper motor as power source, a coupling, a trapezoidal lead screw, a guide shaft, a slider, and a closing / opening lever. The support plate is bolted to the guide slider of two linear guide rails, and the slider moves spatially under the guidance of the linear guide rails. A stepper motor is fixed at the top of the support plate, and the output shaft of the stepper motor drives the trapezoidal lead screw to rotate and the guide shaft to limit the movement, thereby causing the slider fixed on the trapezoidal lead screw to move up and down linearly. A lever customized according to the switching method of 5G circuit breakers is fixed on the closing / opening lever, and the closing / opening lever is fixed to the slider with bolts. After the closing / opening lever clamps the product and moves the lever, it moves up and down linearly together with the slider to test the mechanical life of the product.

[0011] By adopting the above technical solution, the opening and closing tests of various 5G circuit breakers can be performed simply by changing the toggle handle, ensuring the universality of the testing device.

[0012] Preferred configuration: A spring-loaded latch mechanism secures and locks the 5G circuit breaker, pressing the closing / opening lock button at the bottom of the 5G circuit breaker to unlock the closing / opening function of the 5G circuit breaker.

[0013] By adopting the above technical solution, the convenience and security of testing are considered at the same time as locking.

[0014] Preferably, the spring latching mechanism includes a pressure plate, a push switch, a protruding latch, and a spring (405). The pressure plate has guide grooves corresponding to each stage position of the 5G circuit breaker. The 5G circuit breaker is inserted into each guide groove. The spring connected to the pressure plate springs up the pressure plate. The protruding latch on the pressure plate is embedded in the fixing slot of the 5G circuit breaker to fix the 5G circuit breaker. The pressure plate presses the closing and opening lock button at the bottom of the 5G circuit breaker to unlock the closing and opening function of the 5G circuit breaker. The push switch, which drives the pressure plate to descend, releases the 5G circuit breaker that has completed testing and is stuck in the guide groove.

[0015] By adopting the above technical solution, the safety of the test is guaranteed, while also taking into account the convenience of installation and disassembly.

[0016] Preferably, the 5G circuit breaker mechanical life testing device further includes a power-conducting slot plate, which is installed in the power-conducting mounting slot. Several power busbars on the power-conducting slot plate are exposed and directly supply power to the snap-in 5G circuit breaker.

[0017] The safety of powering on was tested by adopting the above technical solution.

[0018] The beneficial effects of this invention are as follows: The 5G circuit breaker mechanical life testing device of this invention simulates the actual installation and power-on conditions of the 5G circuit breaker, and truly reflects the actual effect of the 5G circuit breaker in the base station power cabinet. Moreover, the product is easy and quick to install / disassemble and has high compatibility. By using various moving components to simulate automated working conditions, accurate test results can be obtained. Attached Figure Description

Detailed Implementation

[0026] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. These embodiments are based on the technical solution of the present invention and provide detailed implementation methods and specific operating procedures. However, the scope of protection of the present invention is not limited to the following embodiments.

[0027] like Figure 1 The schematic diagram of the 5G circuit breaker mechanical life testing device shown includes a testing base plate 1, linear guide rails 2, energized mounting slots 3, spring clip mechanism 4, positioning holes 6, and a closing / opening test mechanism 7. The testing base plate 1 is equipped with two linear guide rails 2, one above the other. The closing / opening test mechanism 7 is mounted on the two linear guide rails 2. After the knob plug 8 on the closing / opening test mechanism 7 is rotated and inserted into the positioning hole 6 on the testing base plate 1, the closing / opening test mechanism 7 is fixed to the testing base plate 1. The testing base plate 1 has several positioning holes 6 arranged parallel to the linear guide rails (2). The closing / opening test mechanism 7 moves its spatial position through the two linear guide rails 2, and then selects a fixed position along the guide rail direction through the positioning holes 6, adjusting the position required for the closing / opening test mechanism 7 during testing. Between the two linear guide rails 2, along the moving direction of the opening and closing test mechanism 7, there are several parallel energized mounting slots 3. A spring latching mechanism 4 is fixedly installed on the test base plate 1 directly below each energized mounting slot 3. After the 5G circuit breaker 5 is embedded in the energized mounting slot 3, each stage of the 5G circuit breaker 5 is correspondingly latched into the spring latching mechanism 4 for fixation.

[0028] like Figure 1 , 2As shown, the closing / opening test mechanism 7 includes a support plate 701, a stepper motor 702 as the power source, a coupling 703, a trapezoidal lead screw 704, a guide shaft 705, a slider 706, and a closing / opening lever 707. The support plate 701 is fixed to the guide slider of the linear guide 2 by bolts. The guide slider moves its spatial position under the guidance of the linear guide 2. The stepper motor 702 is fixed at the top of the support plate 701. The output shaft of the stepper motor 702 drives the trapezoidal lead screw 704 to rotate and the guide shaft 705 to limit the movement through the coupling 703, thereby driving the slider 706 fixed on the trapezoidal lead screw 704 to move up and down linearly. The closing / opening lever 707 is fixed with an actuation handle customized according to the switching method of the 5G circuit breaker 5. The closing / opening lever 707 and the slider 706 are fixed by bolts. After the closing / opening lever 707 clamps the product's actuation handle, it moves up and down linearly together with the slider 706 to test the product's mechanical life. If the 5G circuit breaker 5 is a push-button type, then the driving direction will be changed to... Figure 2 Simply move it in a straight line, left or right.

[0029] like Figure 3 The schematic diagram of the spring-loaded latching mechanism 4 shows that it includes a pressure plate 401, a push-button switch 402, a protruding latch 403, and a spring 405. The pressure plate 401 has guide grooves 404 corresponding to each stage position of the 5G circuit breaker 5. After the 5G circuit breaker 5 is engaged in each guide groove 404, the spring 405 connected to the pressure plate 401 springs up the pressure plate 401. The protruding latches 403 on the pressure plate 401 then embed into the product fixing slots to secure the 5G circuit breaker 5. Pressing the closing / opening lock button at the bottom of the 5G circuit breaker 5 with the pressure plate 401 unlocks the closing / opening function of the 5G circuit breaker 5. After testing, pressing the push-button switch 402 lowers the pressure plate 401, releasing the 5G circuit breaker 5 from the guide grooves 404 for easy disassembly.

[0030] like Figure 4 , 5 As shown in Figure 6, the size of the power supply mounting slot 3 is determined according to current actual needs, and the 63A power supply slot plate 9 and 125A power supply slot plate 10 are installed accordingly. Figure 1 , 6 In the power-on mounting slot 3, it is fixed to the other side of the detection base plate 1; several 63A power busbars 901 and several 125A power busbars 1001 on the 63A power-on slot plate 9 and 125A power-on slot plate 10 are exposed, directly supplying power to the snap-in 5G circuit breaker 5. Each mounting slot is compatible with 1-4P (pole) 5G circuit breaker 5 frame products (63A 1-4P, 125A 1-4P); the 5G circuit breaker 5 is inserted into the power busbar provided inside the power-on mounting slot, and the product can be powered on after installation.
