Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electronic detonators, in particular to an anti-short circuit structure of an electronic leg line of a civilian blasting detonator. Background Art
[0002] Electronic detonators are devices used to detonate explosives, commonly used in civilian and military applications. Compared to traditional gunpowder detonators, electronic detonators have greater precision and controllability. They are detonated by an electrical signal and are usually powered by a battery. Electronic detonators can be triggered in a variety of ways, including electronic signals, wireless signals, or remote control. This makes them more flexible and safer in a variety of blasting and demolition tasks.
[0003] Electronic detonators are generally detonated with the aid of an electronic leg wire connected to them. The electronic leg wire is wrapped in a sealing plug. In order to resist static electricity and stray current, the positive and negative electronic leg wires are usually cross-wound. When the electronic leg wire is aged or damaged and peeling, it is easy for direct contact to cause a short circuit, which is dangerous. Moreover, the sealing plug with an integrated structure is difficult to quickly seal and connect with the electronic leg wire, resulting in low production efficiency of blasting detonators and unstable sealing performance. In addition, when the blasting detonator needs to be used underwater, the extended end of the electronic leg wire is directly exposed to the outside, which will cause a short circuit when it comes into contact with water. Utility Model Content
[0004] In order to solve the above-mentioned problems, the utility model proposes an anti-short-circuit structure for the electronic leg wire of a civilian blasting detonator, which can effectively avoid accidental touching of the positive and negative electronic leg wires and can quickly seal and protect the electronic leg wires with good sealing protection.

The periphery is connected to the sealing shell through a fixed structure, and a plurality of fixed plates matching the electronic foot wires are connected inside the sealing shell, the floating plate is integrally formed and arranged at the upper end of the sealing shell, and a plurality of floats are connected below the floating plate through a suspension rope, and the electronic foot wire slides through each fixed plate and the floating plate in turn, and the fixed plate and the floating plate are provided with limiting sliding holes matching the electronic foot wire, the protective cover is fixedly arranged above the floating plate and located around the electronic foot wire, a movable cover is provided at the upper end of the protective cover, and a partition is connected below the movable cover, and the partition is arranged between two electronic foot wires.
[0006] Furthermore, the sealing shell is cylindrical, and the diameter of the lower end of the sealing shell is smaller than the diameter of the upper end.
[0007] Furthermore, the fixing structure includes a fixing block and a fixing bolt, the fixing block is fixed on the cover plate and the side wall of the sealing shell respectively, a fixing hole is provided at the center of the fixing block, and the two fixing blocks are connected and fixed by a fixing bolt passing through the fixing hole.
[0008] Furthermore, the floats are evenly arranged below the floating plate.
[0009] Furthermore, the length of the movable cover is greater than the length of the upper end of the protective cover.
[0010] Compared with the prior art, the utility model has the following advantages: the cross-wound parts of the positive and negative electronic foot wires are fixed and limited by the fixing plate, which can effectively prevent them from contacting each other and causing a short circuit. At the same time, the setting of the partition can also prevent the ends of the positive and negative electronic foot wires from contacting each other and causing a short circuit, and has high safety. The setting of the cover plate can facilitate the rapid fixing of the electronic foot wire in the sealed shell, which is easy to disassemble and assemble. The sealing ring and the sealing strip can ensure the sealing of the connection between the sealed shell and the electronic foot wire, and it has a good waterproof effect, which can effectively prevent the electronic foot wire from short-circuiting when encountering water. The setting of the floating plate can ensure that the electronic foot wire is always above the water surface when the detonator is blasted in the water. The protective cover and the movable cover can further prevent the ends of the electronic foot wire from contacting water, which has a good protective effect and effectively prevents it from short-circuiting.
