Description

Technical Field

[0001] The utility model relates to the field of digital detonators, in particular to a metal split foot line for digital detonators. Background Art

[0002] Digital detonator is an electronic device used to control explosions, usually used in mines, construction sites and military fields. Digital detonator mainly includes detonator, split leg line and detonator, which are connected to blast explosives. It can accurately control the time and intensity of the explosion, improve the safety and efficiency of blasting operations, and ensure the stability, reliability and remote control capability of the detonator.

[0003] Most of the split leg line connectors currently connected to one end of the digital detonator use a plastic structure and are connected by thread or snap-on method. Therefore, the assembly of the digital detonator and the split leg line is troublesome and inefficient. Since the split leg line adopts a plastic structure, the digital detonator connection is prone to breakage and has poor stability when the digital detonator is inserted into the blasting object during use. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a metal split leg wire for digital detonators to solve the technical problems mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a metal split leg line for a digital detonator, comprising a metal connecting tube, a socket is arranged inside the metal connecting tube, and a metal terminal is arranged at one end of the socket, a leg line and a capacitor are installed on one side of the metal terminal, a recess is arranged on one side of the outer wall of the metal connecting tube, and a connecting port is arranged at one end of the metal connecting tube, one end of the metal connecting tube is bent inwardly into an arc shape at the connecting port, an installation port is arranged at the other end of the metal connecting tube, and a cutout is arranged on one side of the socket.

[0006] By adopting the above technical scheme, a recess is provided on the outer wall of the metal connecting tube for convenience in use. When holding the metal connecting tube, fingers touch the recess to increase resistance. The recess forms a limiting portion on the metal connecting tube. The limiting portion is provided to facilitate the installation of the socket and prevent the socket from rotating due to external force. The other end of the metal connecting tube is bent inward to form an arc. Since the metal connecting tube is relatively thin, the arc is provided to prevent the right-angle edge of the metal tube from easily cutting the skin of the foot line and causing damage. The installation opening at one end of the metal connecting tube is longer than the socket socket, so that it is convenient for the metal connecting tube to be fixedly connected to the outer wall of the detonator through mechanical extrusion.

[0007] The utility model is further configured that one end of the socket is provided with a socket.

[0008] By adopting the above technical solution, the detonator can be conveniently connected through the provided socket.

[0009] The utility model is further configured that a sealing ring is arranged inside the socket.

[0010] By adopting the above technical solution, the provided sealing ring can seal the interior of the detonator when it is connected to the socket to prevent water from entering the interior.

[0011] The utility model is further configured that the inner wall of the connecting port is filled with insulating glue.

[0012] By adopting the above technical solution, by filling the inner wall of the connection port at one end of the metal connecting pipe with insulating glue, it is possible to prevent the metal terminals in the metal connecting pipe from contacting and conducting electricity, and the foot wire can be fixed to prevent loosening.

[0013] In summary, the utility model mainly has the following beneficial effects:

[0014] The utility model is provided with a metal connecting tube, a recess and insulating glue. The recess is provided on the outer wall of the metal connecting tube for convenience in use. When the metal connecting tube is held, fingers contact the recess to increase resistance. The recess forms a limiting portion on the metal connecting tube. The limiting portion is provided to facilitate limiting the installation of the socket to prevent the socket from rotating due to external force. The other end of the metal connecting tube is bent inward to form an arc. Since the metal connecting tube is relatively thin, the arc is provided to prevent the right-angle edge of the metal tube from easily cutting the skin of the foot line and causing damage. The installation opening at one end of the metal connecting tube is longer than the socket socket, so that it is convenient for the metal connecting tube to be fixedly connected to the outer wall of the detonator through mechanical extrusion. The hardness is enhanced by the connection between the metal connecting tube and the detonator to prevent the connection of the detonator from breaking when the detonator is inserted into the explosive, thereby improving the stability of the detonator in use.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0022] The following describes an embodiment of the utility model based on its overall structure.

[0023] A metal split leg wire for digital detonators, such as Figure 1 - Figure 5 As shown, it includes a metal connecting tube 1, a socket 3 is arranged inside the metal connecting tube 1, the metal connecting tube 1 is set to a cylindrical shape, a detonator 7 is installed at the end of the metal connecting tube 1, the metal connecting tube 1 and the outer wall of the detonator 7 are fixedly connected by mechanical extrusion, and a metal terminal 4 is arranged at one end of the socket 3, a foot line 2 and a capacitor 5 are installed on one side of the metal terminal 4, a recess 6 is arranged on one side of the outer wall of the metal connecting tube 1, the recess 6 is formed by extrusion, the inside of the metal connecting tube 1 is sunken inward to form a bulge, and a connecting port 11 is arranged at one end of the metal connecting tube 1, one end of the metal connecting tube 1 located at the connecting port 11 is bent inwardly into an arc shape, a mounting port 12 is arranged at the other end of the metal connecting tube 1, and a cutout 33 is arranged on one side of the socket 3.

[0024] See also Figure 2 and Figure 5 One end of the socket 3 is provided with a socket 31, which can be conveniently connected to the detonator 7 through the provided socket 31.

[0025] See also Figure 2 A sealing ring 32 is provided inside the socket 31. The sealing ring 32 can seal the interior of the detonator 7 when it is connected to the socket 3 to prevent water from entering the interior.

[0026] See also Figure 1 The inner wall of the connection port 11 is filled with insulating glue 8. By filling the inner wall of the connection port 11 at one end of the metal connection pipe with insulating glue 8, the metal terminals in the metal connection pipe can be prevented from contacting and conducting, and the foot line 2 can be fixed to prevent loosening.

[0027] The working principle of the utility model is as follows: a recess 6 is provided on the outer wall of the metal connecting tube 1 for convenience in use. When holding the metal connecting tube 1, fingers touch the recess 6 to increase resistance. The recess 6 forms a limiting portion inside the metal connecting tube 1, which fits with the incision on one side of the socket 3 through the limiting portion, thereby achieving the purpose of limiting the installation of the socket 3 and preventing the socket 3 from rotating due to external force. The other end of the metal connecting tube 1 is bent inward to form an arc. Since the metal connecting tube 1 is relatively thin, the arc is provided to prevent the right-angle edge of the metal tube from easily cutting the skin of the foot line 2 and causing damage. The installation port 12 at one end of the metal connecting tube 1 is longer than the socket 31 of the socket 3, so that it is convenient for the metal connecting tube 1 to be fixedly connected to the outer wall of the detonator 7 through mechanical extrusion.
