[0018] The utility model is described in detail below in conjunction with the embodiments shown in the accompanying drawings.

[0019] As shown in the figure, it is a schematic diagram of the structure of the utility model. The figure shows the foot line connected to the metal connecting blade 2 when in use, and the lower end is connected to the digital electronic detonator.

[0021] The plastic part 3 serves as a carrier of the metal short-circuit 1 and the metal connecting blade 2. The plastic part 3 is pressed and fixed on the plastic part 3 by a pressing tool as shown in the figure. By closing the plastic part 3, the metal short-circuit 1 and the metal connecting blade 2 are in contact, so that the two metal connecting blades 2 of the lower cover have a connecting function.

[0022] The plastic part 3 is made of ABS and is divided into an upper cover and a lower cover. The outer dimensions of the upper and lower covers of the plastic part 3 match the dimensions of the production line mold and play a positioning role. The two card slots inside the lower cover are used to embed two metal wiring blades. The tail of the lower cover is designed with a groove for fixing the connecting wires. The card slot inside the upper cover is used to embed the metal short-circuiter 1. The back of the plastic part 3 is used to engrave the detonator coding information; the upper and lower covers are equipped with closing clamps, which can make the upper and lower covers of the wiring card reliably closed.

[0023] Each wiring card of the metal connecting blade 2 is provided with two and is installed on the lower cover. The material is stainless steel. There is a metal groove at each end of the metal connecting blade 2 for clamping the two wires of the electronic detonator.

The function is to close the wiring card. The arc-shaped metal parts at both ends of the short circuit are in contact with the two metal connecting blades 2 of the lower cover to short-circuit the detonator.

[0025] When the wiring card is open, the detection probe of the detection equipment can normally detect the internal electrical properties of the detonator, meeting the function of automated production detection; after production is completed, the wiring card is closed to short-circuit the entire detonator circuit to prevent the entry of stray current, meet the requirements of safe operations at the exploration site, and improve inherent safety.
