[0019] See also Figure 1 The present application provides a circuit board for a digital electronic detonator, including: a circuit board body. The circuit board body is in a convex shape, including: a first boss 5, an inclined section 6 and a second boss 7, the inclined section 6 is between the first boss 5 and the second boss 7, the first boss 5 is a U-shaped structure, and the end of the second boss 7 is an arc. The first pin 1 and the second pin 2 are fixed to the circuit board body through a fixing member 4, and the two ends of the bridge wire 3 are fixed to the top of the first pin 1 and the second pin 2 respectively.

[0020] Specifically, the pins include: a first pin 1 and a second pin 2, the first pin 1 and the second pin 2 are spaced apart and connected by a bridge wire 3, the two ends of the bridge wire 3 are respectively connected to the top of the first pin 1 and the second pin 2, and a bend is respectively provided at the top of the first pin 1 and the second pin 2, and the bridge wire 3 is connected to the bend, and the tail of the first pin 1 and the second pin 2 is respectively connected to the positive electrode and the negative electrode of the power supply. The current of the power supply flows from the positive electrode of the power supply through the first pin 1, the bridge wire 3 and the second pin 2 back to the negative electrode of the power supply.

[0021] Specifically, since the first pin 1 and the second pin 2 are separately arranged, the fixing member 4 needs to be arranged at the tail ends of the first pin 1 and the second pin 2 to position the first pin 1 and the second pin 2. In this way, the gap between the first pin 1 and the second pin 2 is maintained to ensure that the first pin 1 and the second pin 2 are connected through the bridge wire 3, so that when the current passes through the bridge wire 3, the bridge wire 3 with large resistance instantly generates a large amount of heat to ignite the ignition powder.

[0022] In one embodiment, the first pin and the first portion of the second pin are disposed on the first boss of the circuit board body; the fixing member and the second portions of the first pin and the second pin are disposed on the inclined section of the circuit board body.

[0023] Specifically, the shape of the circuit board for digital electronic detonators is set to be a convex shape, including: a first boss 5, an inclined section 6 and a second boss 7, and the first pin 1 and the second pin 2 are fixed to the upper surface of the circuit board through a fixing member 4. The specific method is to first fix the first pin 1 and the second pin 2 with a fixing member 4, wherein the fixing member 4 is an insulating material, and then weld the fixed first pin 1 and the second pin 2 to the solder pad reserved on the circuit board. Among them, when welding, it is necessary to ensure that the bridge wire 3 and the first part of the pins are set on the first boss 5 of the circuit board, and the fixing member 4 and the second part of the pins are set on the transition section 7 of the circuit board. In this way, the bridge wire 3 is set on the first boss 5, which effectively prevents the bridge wire 3 from being too thin and breaking during production or transportation.

[0024] In this embodiment, the circuit board for digital electronic detonators provided by the present application includes: a circuit board body, the circuit board body is convex, including: a first boss 5, an inclined section 6 and a second boss 7, the first pin 1 and the second pin 2 are fixed to the circuit board body through a fixing member 4, and the two ends of the bridge wire 3 are respectively fixed to the top of the first pin 1 and the second pin 2; wherein, the bridge wire 3 and the first pin 1 and the second pin 2 of the first part are arranged on the first boss 5 of the circuit board body; the fixing member 4 and the first pin 1 and the second pin 2 of the second part are arranged on the inclined section 6 of the circuit board body. The circuit board of the present application is convex, the bridge wire 3 and the first part pins are arranged on the first boss 5 of the circuit board, and the fixing member 4 and the second part pins are arranged on the inclined section 6 of the circuit board, so that the first boss 5 protects the bridge wire 3 and effectively prevents the bridge wire 3 from breaking.

[0025] In one embodiment, the first boss 5 of the circuit board body is a U-shaped structure, and the bridge wire is arranged in the U-shaped structure of the first boss. The length of the bridge wire is greater than the width of the U-shaped structure. The bridge wire is V-shaped, and the tip of the V-shaped is facing the opening of the U-shaped structure. Such a design allows the bridge wire to be combined with the circuit board, increases the area available for drug dipping, facilitates drug dipping, and ensures that the drug head is not easy to fall off after drug dipping.

[0026] Specifically, the first pin 1 and the second pin 2 are arranged separately on the first boss 5 of the circuit board for the digital electronic detonator, and the first pin 1 and the second pin 2 are connected by a bridge wire 3, and the two ends of the bridge wire 3 are respectively connected to the top of the first pin 1 and the second pin 2, and a bend is provided at the top of the first pin 1 and the second pin 2, and the bridge wire 3 is connected to the bend, and the bridge wire 3 is V-shaped, and the tip of the V-shape faces the opening of the U-shaped structure, and the tail of the first pin 1 and the second pin 2 are respectively connected to the positive and negative poles of the power supply. In this way, it can be ensured that the bridge wire 3 is arranged in the area of ​​the U-shaped structure, and the bridge wire 3 is matched with the main body of the circuit board, so that the circuit board protects the bridge wire 3, avoids the bridge wire 3 from being easily broken during production and transportation, and ensures that the medicine head is not easy to fall off after dipping.
