The connection between the detonator leg wire and the connecting wire is generally that the wire core is wound and then wound by an insulating tape, and finally the connecting wire is bound on the charge column body for a circle, and the connected charge column is conveyed to the bottom of a well by an explosion rod to complete charge.

In the above wiring method, although the leg wire and the connection wire can be connected, in practical use, we find that there are certain disadvantages, such as:

1. in the wiring mode, the detonator leg wire and the connecting wire are manually wound and then are wound with the insulating adhesive tape, so that the detonator leg wire and the connecting wire are often not firm enough and are easy to slip in the process of feeding the explosive to the bottom of a well, and the broken circuit is caused, so that a blind shot is caused;

2. the wiring mode is insufficient in protection of the circuit, and the connecting point is easily extruded and damaged by an explosion rod head in the explosive charging process, so that short circuit and open circuit are caused, and a blind shot is caused;

3. the stress position of the wiring mode circuit is not clear, so that the detonator leg wire is easy to break, and open circuit is caused, and a blind shot is caused;

based on the device, the connecting device for the pin wire and the connecting wire of the electric detonator for seismic exploration is provided.
