[0023] Embodiment:

[0024] Figure 1 It is a schematic diagram of the structure of the head of a detonator. The head structure includes a base 1 and side plates 2 provided at both ends of the base 1. An empty groove 201 is provided on the outer side of the side plate 2, and a groove inner wall is provided on the inner side. A sunken groove 203 is provided in the middle of the groove inner wall. An installation hole position 204 is provided at the bottom of the empty groove 201, and an installation hole 205 penetrating the base 1 is provided in the installation hole position 204. The base 1 is further provided with a first connection hole 3 and a second connection hole 5. The first connection hole 3 is used for installing a signal receiving device, such as installing an antenna 4, and can also be customized according to customer needs. The second connection hole 5 is used for fixing to the detonator.

[0025] The present utility model provides the empty groove 201 to facilitate the opening of the installation hole 205, leaving sufficient space for the installation of the installation hole 205 onto the detonator, and the installation is more stable and tight. Moreover, the empty groove 201 can reduce the weight of the entire head structure. The sunken groove 203 can provide space for laying cables without affecting the installation of the antenna 4. The installation hole position 204 is larger than the installation hole 205, which does not affect the installation and disassembly of bolts.

One end of the shoulder step 202 is connected to the side plate 2 and the connection part is a rounded corner structure, and the other end is connected to the edge of the sunken groove 203 and the connection part is a rounded corner structure. The design of the shoulder step 202 can form the sunken groove, and the rounded corner design will not damage workers or cables, and has good safety performance.

[0027] On both sides of the mounting hole 204, there are high steps 206. One end of the high step 206 is connected to the side plate 2, and the connection part is a rounded corner structure. The other end is connected to the edge of the mounting hole 204, and the connection part is also a rounded corner structure. The high step 206 is lower than the surface of the base 1, and the mounting hole 204 is lower than the high step 206. The high step 206 is located at the bottom of the side plate 2, strengthening the stability and strength of the side plate, and ensuring that there will be no unstable situation after being installed on the detonator. The height design of the base 1, the high step 206, and the mounting hole 204 makes the position of the mounting hole 205 thinner, which is more convenient to use with bolts.
