A sliding sleeve 17 is slidably mounted on the surface of truss 16, and a fan 18 is provided on one side of sliding sleeve 17, which moves back and forth along the surface of truss 16 with sliding sleeve 17. A telescopic cylinder 19 is attached to one side of fan 18, which controls the movement of sliding sleeve 17 across the surface of truss 16. Telescopic cylinder 19 is fixed to one side of frame 15.

[0031] A circuit board disconnect detection device includes a dustproof assembly 3 mounted directly above a circuit board 8 to directly remove dust from the surface of the circuit board 8. Grease is applied to the surface of the truss 16 to enhance the sliding effect of the sleeve 17 on the surface of the truss 16. The truss 16 is installed perpendicular to the bracket 1.

[0032] A circuit board circuit break detection device, a multimeter 20 is connected to an external power supply, and a power ring 6 and a slot 7 adopt a nested plug-in structure to avoid the problem of unstable plugging of an electric pen 10 inside the slot 7.

[0033] Working principle:

[0034] In the actual innovation process of the present invention, in order to avoid the following defects existing in the prior art: "When performing circuit breakage detection on the circuit board in the prior art, various methods are mainly used to control the electric pen to touch various points on the circuit board, and the display effect of the multimeter is used to understand whether the specific location has a circuit breakage problem. However, the circuit accuracy on the surface of the circuit board is very high. Frequent use of the electric pen for squeezing and touching may not only cause poor contact and inaccurate detection, but also the risk of damaging the surface of the circuit board due to long-term touch." The embedded detection component 2 and the dustproof component 3 are specifically proposed.

[0035] During use, the circuit board 8 to be tested is inserted and installed inside the positioning box 4 to achieve positioning. The connectors at both ends of the circuit board 8 contact the conductive plates 5 to complete the circuit. The two test pens 10 are inserted into the electrical connection ring 6. The test pens 10 connect to a multimeter 20 via wires 13 to test the circuit. By controlling the control keys 12 on the surface of the multimeter 20, the on / off status of the circuit is displayed on the display 11. A protective cover 9, which is fastened to the surface of the circuit board 8, protects it from damage during testing.

[0036] To provide a dust-free environment for circuit boards 8 during testing, a frame 15 is installed on the side of bracket 1. A truss 16 and a sliding sleeve 17 slide on top of frame 15. A telescopic cylinder 19, via a telescopic rod, controls a fan 18 on sliding sleeve 17 to reciprocate across the surface of truss 16. The air blown by fan 18 removes dust adhering to the surface of the testing device.

[0037] The present invention utilizes an embedded detection assembly 2, replacing the traditional touch-sensitive detection method of an electric pen 10 with an embedded detection method. This detection method effectively protects the circuit board's surface circuitry while preventing poor contact at certain points, thereby improving detection accuracy. The dustproof assembly 3 ensures that the circuit board 8 remains in a dust-free or low-dust environment during the detection process, significantly protecting the circuit board 8 and preventing damage from dust accumulation during testing.
