Description

Technical Field

[0001] The utility model relates to the technical field of circuit breaker reliability testing, in particular to an Internet of Things circuit breaker aging testing device. Background Art

[0002] In the process of producing IoT circuit breakers, in order to detect the reliability of internal circuit boards, operating mechanisms, etc., power-on operation aging tests will be carried out before leaving the factory. Problems can be discovered during the test and failed products can be filtered out to ensure the reliability and pass rate of the output products.

[0003] During the entire aging test process, the working state of the IoT circuit breaker will be switched to the aging test state through an external signal or a switch setting on the circuit breaker, so that the circuit breaker performs a specific number of opening and closing operations (generally dozens to hundreds of times, which can be set according to technical regulations).

[0004] At present, in the existing aging test methods, it is generally necessary to manually insert the signal plug into the specified position so that the circuit breaker starts to age. Or switch the specific switch on the circuit breaker to let it enter the aging mode. After the aging test is completed, the signal plug must be unplugged; or the specific switch on the circuit breaker must be switched back to the normal working position. This operation increases the workload of production personnel and increases operational risks. For example, after the aging test of the IoT circuit breaker is completed, the production personnel negligently fail to switch the specific switch on the circuit breaker back to the normal working position, and the product is packaged and sold to the customer. After the customer receives the product, it will not work properly.

[0005] By designing a plug-and-socket interface on the IoT circuit breaker, or designing a specific aging switch, the appearance integrity of the circuit breaker is bound to be destroyed, and the interface cost expenditure is also increased. Uninformed users will also increase the risk of incorrect use. Utility Model Content

After the Hall element 20 senses the electromagnetic signal, it outputs a trigger signal to the main circuit board 10 for reading and judgment. The controller controls the type of the electromagnetic signal to switch the Internet of Things circuit breaker between the aging mode and the normal working mode.

The Hall element 20 is a Ge Hall element, a Si Hall element, an InSb Hall element, a GaAs Hall element, an InAs Hall element, an InAsP Hall element, or a multilayer semiconductor heterostructure quantum well Hall element, or other types of Hall elements.

[0033] In order to protect the IoT circuit breaker without interfering with the transmitted signal, in one embodiment, the IoT circuit breaker aging test device also includes a shell arranged on the IoT circuit breaker, which is used to fix the main circuit board 10 of the IoT circuit breaker, and the shell is a plastic shell or a ceramic shell.

[0034] By setting up the shell, the IoT circuit breaker is protected and the main circuit board 10 is fixed, which ensures the signal stability of subsequent tests and improves the test efficiency. The material, shape and thickness of the shell are not limited in this application.

[0035] In the present application, the signal is transmitted through the Hall element 20, and the specific setting position and connection method of the Hall element 20 are not limited.

Through the groove, the centerline axis of the Hall element 20 can be quickly aligned with the central axis of the electromagnetic component 30, and accurate alignment can be automatically achieved without subsequent position adjustment, thereby improving the installation efficiency and subsequent testing efficiency.

[0041] Furthermore, in order to achieve position adjustment and avoid subsequent signal errors that may be caused by installation position deviation, in one embodiment, the groove is movably connected to the rail 40, and the controller controls the position of the groove on the rail 40 to achieve the coincidence of the centerline axis of the Hall element 20 with the central axis of the electromagnetic component 30.

[0042] By movably connecting the groove with the rail 40 , the position of the groove can be controlled by a motor or other structure, thereby achieving precise adjustment of the position of the Hall element 20 .

It can also be other agreed frequencies), and the Hall element 20 inside the IoT circuit breaker receives the electromagnetic signal and presents an agreed period, the IoT circuit breaker will automatically enter the aging mode and perform the aging work.
