With the development of technology and the improvement of application requirements, higher requirements are put forward for the reliability and safety of electronic detonators. Among them, as an important part of the ignition system of electronic detonators, the stability and protection mechanism of the bridge wire are directly related to the initiation performance and safety of the detonator.

[0003] There are still some deficiencies in the existing protection structures for the bridge wire of electronic detonator chips during actual use:

[0004] 1. Although the existing protection structures for the bridge wire of electronic detonator chips can play a certain role in protecting the bridge wire, the wrapping of the electrode plates is not comprehensive enough, and the bridge wire is easily broken or damaged due to impact during transportation or installation.

[0005] 2. The existing protection structures are relatively complex, resulting in a cumbersome installation method, which easily increases the production cost and manufacturing difficulty. Content of the Utility Model

[0006] The purpose of the utility model is to solve the shortcomings in the existing technology, such as the incomplete wrapping of the electrode plates, the easy breakage or damage of the bridge wire due to impact during transportation or installation, and the relatively complex protection structure, and to propose a protection structure for the bridge wire of an electronic detonator chip.

[0007] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0008] A protection structure for the bridge wire of an electronic detonator chip includes a top cover and a bottom bin, and the top cover covers the top of the bottom bin. A placement bin is arranged in the bottom bin, a support platform is fixedly connected in the bottom bin, electrode plates are placed on the placement bin and the support platform, and an embedding block is fixedly connected to the bottom of the top cover and covers the electrode plates.

[0009] In a possible design, a medicine storage bin is arranged in the bottom bin, and the medicine storage bin is located on the side of the support platform away from the placement bin. One inner wall of the medicine storage bin is rotatably connected to a cover plate through a rotating shaft, one end of the electrode plate extends into the medicine storage bin, and the cover plate covers the electrode plate by flipping.

[0010] In a possible design, two first connectors are fixedly connected to the bottom of one end of the top cover, two second connectors are fixedly connected to the top of the bottom bin, a connecting shaft passes through the two first connectors and the two second connectors, and the two first connectors are located between the two second connectors.

[0011] In a possible design, two sliding grooves are provided in the bottom bin, a limiting block is sleeved on the outer wall of the connecting shaft, sliding blocks are fixedly connected to both sides of the limiting block, and the sliding blocks are slidably connected in the sliding grooves.

[0013] In a possible design, a clamping groove is provided at the top of the bottom bin, a clamping block is fixedly connected to the bottom of the top cover, and the clamping block and the clamping groove are clamped and matched.

[0014] In this application, when the top cover is applied to the detonator fuse, the lead wire can pass through between the first arc-shaped opening and the second arc-shaped opening and extend into the medicine storage bin. The gunpowder is directly placed in the medicine storage bin, the electrode plate is placed in the placement bin and the support platform, one end of the electrode plate extends into the medicine storage bin where the gunpowder is placed, the cover plate is covered to seal the gunpowder. First, the limiting block and the bottom bin are slidably limited through the sliding blocks in the sliding grooves, and then the top cover is covered on the top of the bottom bin.
