Detailed Description

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are for purposes of illustration only and are not intended to limit the scope of the present invention.

The embodiment provides an electronic control module of an electronic detonator, which comprises an ignition device 1, an energy storage capacitor 2, a PCB (printed circuit board) 3 of a control circuit PCBa, a leg wire terminal 4 and a plastic package block 5, as shown in figures 1 and 2.

The PCB board 3 of the control circuit PCBa is provided with a slotted hole, the energy storage capacitor 2 is embedded in the slotted hole, and is connected with the PCB board 3 of the control circuit PCBa through wiring, the ignition device 1 is connected with the smaller end of the PCB board 3 of the control circuit PCBa away from the energy storage capacitor 2, the leg wire terminal 4 is connected with the other end of the PCB board 3 of the control circuit PCBa, namely, the distance between the leg wire terminal 4 and the energy storage capacitor 2 is greater than the distance between the ignition device 1 and the energy storage capacitor 2, meanwhile, the energy storage capacitor 2 can be arranged in an area close to the ignition device 1 to the maximum extent, so that large-section wiring of the PCB board 3 of the control circuit PCBa on the PCB board is reduced, only a switch and a switch control loop are arranged between the two, and a PCB board process edge can be arranged at one end without the ignition device, and the process edge can be kept to flow and transfer to injection molding, medicine dipping, drying and other post-process steps. Simultaneously, this kind of structural design can set up PCB board technology limit at the one end that control circuit PCBa's PCB board 3 does not have ignition device 1, and this technology limit can keep the cocurrent flow to the back process such as moulding plastics, dip in the medicine, stoving, then can guarantee that the back process uses, transports, need not to increase card strip or the cassette that has the locate function in the storage.

The plastic package piece 5 cover is established on control circuit PCBa's PCB board 3, make energy storage capacitor 2, the piece of moulding plastics on the device 1 of igniting, switch and on-off control circuit establish inside plastic package piece 5, the one end of plastic package piece 5 is located the tip at device 1 place of igniting on control circuit PCBa's PCB board 3, the other end is located the region between the tip that foot line terminal 4 is close to energy storage capacitor 2 and switch and on-off control circuit, make foot line terminal 4 not establish the inside at plastic package piece 5, foot line terminal 4 exposes promptly, make foot line terminal 4 become a removable independent device, be convenient for maintain or change, even under extreme condition, can directly weld the foot line on the pad that foot line terminal 4 corresponds.
