However, in order to upgrade the industry gradually, the enterprise cost is reduced, the labor consumption is reduced, the production process of the digital electronic detonator module PCB is gradually replaced by automation equipment, and the existing technology can be used for automatically producing the digital electronic detonator module PCB. But now the problem is how to ensure that the position of the components is accurate in the production link, while at the same time a simple low cost solution is adopted. Based on this, the present patent proposes a new solution.

Detailed Description

Preferred embodiments of the present utility model are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are merely for explaining the technical principles of the present utility model, and are not intended to limit the scope of the present utility model.

Referring to fig. 1-3, the utility model provides a digital electronic detonator module plug-in PCB board. The PCB is provided with a bayonet 1 for placing and limiting components 3. Referring to fig. 2 and 3 in detail, when the component 3 is placed in the bayonet 1, the component 3 sinks into the bayonet 1 and extends to the other side of the PCB board. The bayonet 1 supports and limits the component 3 by means of its edges. Therefore, in the automatic production process of the digital electronic detonator module, the position of the component 3 on the PCB can be accurate.

Such a solution is currently particularly suitable for the rapid installation of simple and small numbers of components 3. For example, in the production process of the digital electronic detonator module, the last component 3 to be installed on the PCB is a capacitor, and the capacitor has only two pins, so that the PCB is provided with a bayonet 1 which is suitable for the size of the capacitor to position and limit the capacitor, thereby being very convenient for subsequent automatic production. In the prior art, workers are generally required to manually weld the capacitor, after the capacitor is in place, a batch of PCB (printed circuit board) can be placed into automatic welding equipment for automatic welding, and the problem of capacitor position change is not required to be worried in the transportation process. Meanwhile, the capacitor is placed in the bayonet 1, so that the protruding height of the capacitor from the PCB is reduced, and the assembly of the detonator is very facilitated for products with small size and precise structure of the detonator. From the prior art, the capacitor is directly fixed on the surface of the PCB board, which causes trouble to the assembly of the detonator. Indeed, the beneficial effect of being able to reduce the height of the protrusions in this way is equally applicable to other non-compliant components 3 and to different production fields.

The PCB is provided with a connecting hole 2 for connecting pins of the component 3. When the component 3 is placed in the bayonet 1, the pins are inserted into the connecting holes 2, and the soldering tin flows into the connecting holes 2, so that the pins can be sufficiently and firmly fixed, and the soldering tin and the pins have large contact area and can be sufficiently contacted with the PCB and the pins; at the same time, fluctuations in the soldering strength can be reduced, since only the soldering tin has to be filled into the connection holes 2. The connecting holes 2 are arranged in an oval shape. The bending angle of the pins of each component 3 is different, limited by the production process of the component 3. The oval connecting hole 2 can be matched with pins with various bending angles.
