[0002] Detonator inspection is a critical step in traditional open-pit blasting operations. Traditional methods rely on manual inspection or simple fire control systems. Existing detonator inspection methods typically require the detonator detector's contacts to directly contact the detonator. This approach is not only inconvenient but also prone to wear and tear, reducing inspection efficiency. Furthermore, the connection of single-shot detonators is complex and prone to connection failures, resulting in detonator malfunction.

[0003] At present, some digital detonator detection devices have been developed, but most of them are limited to the detection of multiple detonators and lack connection devices specifically for the detection of single detonators. The connection problem of single detonators mainly relies on manual operation, which carries risks such as easy wear of contacts and poor connection firmness.

[0004] Therefore, a digital electronic detonator single-shot detection connection device is designed, which reduces the wear of the detonator detector contacts, facilitates the blaster's operation, and improves the initiator detection efficiency. Summary of the Invention

Due to the elastic properties of the plastic material itself, the conductive claws 3 installed on the base 2 have the property of position rebound.

[0029] The above scheme ensures a reliable connection between the detonator detector and the initiator contact 2000 when conducting single-shot detection of digital electronic detonators, and then the sleeve 4 is spirally rotated and connected to the conductive clamp 3, which makes it more convenient to quickly install and disassemble the detection device, improves the stability and convenience of the connection device, realizes accurate detection of digital electronic detonators, and ensures the safety and accuracy of the detection process.

[0030] The inner wall of the sleeve 4 is provided with an internal thread, and the side where the conductive clamp 3 is connected to the inner wall of the sleeve 4 is provided with an external thread. At least three conductive clamps 3 are provided, and a cutout 301 is provided on the inner side of the conductive clamp 3. A metal joint 302 is provided at the tail end of the conductive clamp 3, and the metal joint 302 is connected to the wire 1000. Through the above scheme, the conductive clamp 3 can be firmly screwed into the interior of the sleeve 4, and the gap between the conductive clamps is effectively reduced during the rotation process, so that the contact with the detonator is more accurate and reliable, and the external power supply is effectively conducted, which effectively ensures the stability and reliability of the connection device, and ensures that the detection work can be completed accurately and safely in actual use.

[0031] The above-mentioned connecting device also includes a fixing part 5, which has an installation cavity 501.

[0032] Working principle:

[0033] The conductive clamp 3 passes through the body of the fixing part 5 through the clamp through-hole 503.

The detonator detector is connected to the detonator contact 2000 through the wire 1000 to ensure that there is no looseness between the detonator detector and the detonator, providing a reliable detection connection. The detection device makes the connection between the detonator detector and the detonator contact 2000 more reliable, facilitates quick installation and disassembly, and improves the safety and accuracy of the detection process.
