Description

Technical Field

[0002] At present, electronic detonators are widely used in occasions such as tunnel excavation, dangerous blasting, demolition blasting, ore-rock separation, open-pit blasting, etc. The electronic detonator control module in the electronic detonator is the main detonation control part of the electronic detonator. The stability of the electronic detonator control module will directly affect the stability of the electronic detonator. The electronic detonator control module mainly includes a control circuit board and electronic components such as an integrated control chip, an ignition element, and an energy storage capacitor installed on the control circuit board.

[0003] Furthermore, with the wide application of electronic detonators and the diversification of usage scenarios, the market has put forward higher requirements for the structural design and performance of electronic detonator control modules. For example, there is a greater demand for the capacity of the energy storage capacitor, so it is necessary to install a larger-sized energy storage capacitor on the control circuit board of the electronic detonator control module to increase the capacity of the energy storage capacitor; further, in order to improve the performance of the electronic detonator control module, it is necessary to arrange more electronic components and lay out more complex circuits on the control circuit board of the electronic detonator control module. When using the control circuit board of the existing electronic detonator control module to arrange more electronic components and lay out more complex circuits, the control circuit board of the existing electronic detonator control module often has difficulty providing sufficient layout space for arranging more electronic components, and the circuit layout space often faces the problem of insufficient space; if a circuit control board with a wider size is used, it will increase the width dimension of the control circuit board, and then lead to an increase in the overall width dimension of the electronic detonator control module, making the electronic detonator control module thick and even exceeding the suitable width dimension range. In addition, if a circuit control board with a longer size is used, it not only increases the difficulty of processing the circuit control board with a longer size, but also easily reduces the yield rate of the circuit control board. Therefore, there is an urgent need for an electronic detonator control module that is conducive to arranging more electronic components and facilitating the provision of sufficient circuit layout space.
