[0060] The casing 1 shields the connection area between the electronic detonator body and the lead wire 6, while the sealing ring 11 ensures a waterproof seal and a secure connection, allowing the electronic detonator to function properly. The fastening ring 231 prevents the electronic detonator body from detaching from the casing 1.

[0074] The first clamping body 332 is arranged on the outer side surface of the tail end of the first center column 331, and the head end of the first clamping body 332 is provided with a first annular groove 3321 between the outer surface of the first center column 331; the tail end of the insert 32 is clamped in the first annular groove 3321; the first clamping body 332 is provided with a first accommodating notch 3322 penetrating through; the insert 32 is electrically connected to the electronic detonator body through the first accommodating notch 3322.

[0075] The first glue block can separate the center needle 31 and the insert 32, so that the two are insulated, and the positions of the two are relatively fixed, and the relative positions of the two and the tube shell 1 are fixed, to provide a stable position for connection with the second plug-in part.

[0081] In the embodiment, the head end surface of the sealing plug body 4 is provided with an accommodating groove 41;

[0082] The second plug-in part further comprises a second rubber block arranged in the accommodating groove 41, and the second rubber block comprises:

[0083] A second center column 531 is provided with a second through hole 5311 along its axis; the center tube 51 is arranged in the second through hole 5311, and the head portion protrudes from the head end of the second center column 531; the fitting member 52 is sleeved on the second center column 531; and the necked portion 521 is located outside the head end of the second center column 531.

[0084] A second clamping body 532 is arranged on the outer side of the tail end of the second center column 531, and a second annular groove is arranged between the head end of the second clamping body 532 and the outer surface of the second center column 531; the tail end of the fitting member 52 is clamped in the second annular groove; at least one second accommodating notch 5322 is arranged through the second clamping body 532; and the plug-in member 32 is electrically connected with the head end of the lead wire 6 through the second accommodating notch 5322.

[0085] The accommodating groove 41 can be integrally formed with the plug-in member 4 by injection molding after the second plug-in part is connected with the lead wire 6. The second accommodating notch 5322 arranged on the second clamping body 532 can fix the second rubber block with the plug-in member 4, and relative rotation and the like do not occur.

[0086] In the embodiment, the tail portion of the plug-in member 4 is provided with a diameter expansion portion 42, and the diameter expansion portion 42 forms a stepped surface 421 with the head portion of the plug-in member 4; after the head portion of the plug-in member 4 is plugged into the head end of the tube shell 1, the second plug-in part is electrically connected with the first plug-in part, and the end surface of the head end of the tube shell 1 abuts against the stepped surface 421.

[0087] The stepped surface 421 can be used to intuitively determine whether the first plug-in part and the second plug-in part are effectively electrically connected, and also facilitates checking whether the first plug-in part and the second plug-in part are relatively separated after being connected.

[0088] In the embodiment, the electronic detonator body is as shown in the drawing, and comprises an electronic component 22, an initiating explosive 21 arranged at the tail portion of the electronic component 22, and an injection molding rubber 23 integrally fixing the electronic component 22. Figure 3

[0089] The special plug-in member 32 of the embodiment is produced by injection molding and the like to obtain the first rubber block and the second rubber block.

[0090] ​The center needle 31 is inserted into the first through hole 3311 of the first center column 331, and then the insert 32 is sleeved outside the first center column 331, and the tail of the insert 32 is inserted into the first annular groove 3321. Then, the center needle 31, the insert 32 and the electronic component 22 are welded and fixed, and then the electronic component 22 and the first plug-in part are integrally placed into an injection molding machine to complete injection molding 23, so that the first glue block and the electronic component 22 are fixed as a whole, and a sealing ring 11 is formed on the surface of the injection molding 23.

[0091] The detonating agent 21 is placed at the bottom of the tube shell 1, and then the electronic detonator body and the first plug-in part completed by the injection molding 23 are placed into the tube shell 1, and the detonating contact on the electronic detonator body is located in the detonating agent 21.

[0092] Then, the center tube 51 is placed into the second center column 531, the connector 52 is sleeved outside the second center column 531, and the tail of the connector 52 is inserted into the second annular groove. Then, the leg wire 6 is welded with the center tube 51 and the connector 52, and finally the whole is placed into an injection molding machine to obtain an integrated sealing plug body 4.

[0093] Before installation, according to the difference (positive difference or negative difference) between the outer diameter of the center needle 31 and the inner diameter of the center tube 51, if the outer diameter of the center needle 31 is greater than the inner diameter of the center tube 51, direct plug-in installation can be performed; if the outer diameter of the center needle 31 is less than or equal to the inner diameter of the center tube 51, the head end of the center tube 51 is pinched to reduce the inner diameter of the head end to be less than the outer diameter of the center needle 31, and then plug-in installation is performed.

[0094] The plug-in installation process is as follows: the sealing plug body 4 is inserted into the opening of the tube shell 1, as the insertion depth increases, the insert 32 contacts the necked portion 521 of the connector 52, and is deformed (the outer diameter is reduced) by the necked portion 521 with continuous insertion to form an interference fit with the necked portion 521. At the same time, the center needle 31 also extrudes the center tube 51, forcing the head end of the center tube 51 to deform (the inner diameter is enlarged), also forming an interference fit.

[0095] Until the end surface of the tube shell 1 abuts against the step surface 421, at which time the plug-in installation is completed.
