Problems solved by technology

However, the line cards commonly used in domestic electronic detonators are almost non-waterproof line cards. During the rainy season and underground blasting such as tunnels, many communication errors caused by water ingress in the clips often occur, which brings great harm to blasting operators. It seriously affected the construction progress, and during the investigation process, it also caused some unsafe problems due to the continuous interference of the operators on the network.

Embodiment 1

[0038] Embodiment 1: see Figure 1 to Figure 3 , the connection mode of the electronic detonator line card 24 and the electronic detonator 23 refers to figure 1 , the expansion diagram of the electronic detonator line card 24 is as follows figure 2 , wherein the structure of the line card shell 25 and the sheet staple 26 is as follows figure 2 , the sheet-shaped staple 26 is exactly two symmetrically arranged metal sheets, and the inside is provided with a slot for the network cable to snap in, and then the line card shell 25 is also provided with a crimping tooth 27 and a card groove 28, and the crimping tooth 27 The purpose is to press the network cable into the sheet-shaped staple 26 and the draw-in groove 28 .

[0039] It can be seen that the structure is not only very complicated, but also difficult to process, and it is a non-waterproof line card. During the rainy season and underground blasting in tunnels, many communication errors caused by water ingress of the card ...

Embodiment 2

[0040] Example 2: see Figure 4 to Figure 8 , a waterproof line card for industrial digital electronic detonator 23, which is used to snap into a network line, the network line includes an insulating layer and an inner core, and the waterproof line card for industrial digital electronic detonator 23 includes a housing 1 and a A matching cover 3, the cover 3 is located above the casing 1, one side is connected to the casing 1 through the connecting part 2, and can be folded to be buckled with the casing 1, and the casing 1 includes a front side , the rear side, the left side, the right side and a bottom surface, the side connected to the cover body 3 is the rear side, and the inner bottom surface of the housing 1 is provided with a ring-shaped first middle protective layer 4, the first A positioning groove 6 is respectively provided on the left and right sides of the middle protective layer 4, and a clamping nail 7 is respectively provided in the positioning groove 6;

Abstract

The invention discloses a waterproof line card for an industrial digital electronic detonator, which is used for snapping into a network line. The invention changes the structure of the original line card. On the basis of the original box body and cover body, three layers of inner, middle and outer layers are set. Waterproof structure, in which, an inner protective layer is set to cover the positioning groove to play the first layer of waterproofing inside, and the first middle protective layer and the second middle protective layer are set to play the second layer of waterproof in the middle, which can be reused The two-step stepped structure at the junction of the shell and the cover serves as the third layer of waterproofing for the outside. A series of auxiliary waterproof structures are also set up. The structure of the clipping nail is special, combined with the structure of the inner protective layer and the second middle protective layer, it can make the installation of the network cable very simple, and the installed network cable can be effectively positioned. The present invention plays a role in the smooth promotion of domestic electronic detonators. It plays a positive role, and at the same time enhances the international competitiveness of China's civil explosive products. Adapt to various complex blasting environments, such as large dust, water and high temperature environments.

Description

technical field [0001] The invention relates to a line card for an electronic detonator, in particular to a waterproof line card for an industrial digital electronic detonator and an installation method. Background technique [0002] As an intelligent and safe detonating device, the electronic detonator has been promoted by the Ministry of Public Security and the Ministry of Industry and Information Technology as a technological product for safe explosion control. It is expected that the electronic detonator will completely replace the ordinary detonator in 2025. On the one hand, the product has a much higher safety performance For general industrial detonators, use the application code detonation technology. On the other hand, the product can realize the traceability of the whole life cycle, which is of great significance to improve the control of social public safety. The product is mainly composed of electronic detonator tube body, foot wire, line card and information la...
