Description

TECHNICAL FIELD

[0001] The utility model relates to electronic detonator structure technical field, especially electronic detonator packaging structure. BACKGROUND

[0002] Electronic detonator, also called digital electronic detonator, digital detonator or industrial digital electronic detonator, is an electric detonator using an electronic control module to control the detonation process. The electronic control module refers to a special circuit module placed inside the digital electronic detonator, which has the functions of detonator delay time control and detonation energy control, and is built-in with detonator identity information code and detonation password. It can test its own functions, performance and the electrical properties of detonator ignition elements, and communicate with detonation controllers and other external control devices.

[0003] When the electronic detonator is installed, the tube opening is blocked by the tube plug. When the tube plug is inserted into the tube opening, the tube plug is in close contact with the inner wall of the tube shell due to its long length. During the process of inserting the tube plug, the pressure inside the tube shell is greater than the pressure outside. If the pressure inside the tube shell is greater than the pressure outside for a long time, it will affect the close contact between the tube plug and the tube shell, and further affect the packaging tightness of the electronic detonator, thereby affecting the performance of the electronic detonator. To solve the above problems, the utility model provides a solution. UTILITY MODEL CONTENT

[0004] The utility model aims at providing an electronic detonator packaging structure.

[0005] The above technical purpose of the utility model is realized by the following technical scheme:

[0006] An electronic detonator packaging structure comprises a tube shell, a tube plug and an electric control module. The open end side wall of the tube shell is provided with two inner grooves. The side wall of the tube plug is provided with two positioning grooves matched with the inner grooves. The outer end of the tube plug is provided with a slot. The slot is provided with a plug hole penetrating along the axial direction of the tube plug. A plug rod is inserted and fixed in the plug hole. The plug rod is in interference fit with the plug hole. The upper end of the plug rod is fixedly connected with a plug block. The plug block is installed in cooperation with the slot. The upper end of the electric control module is provided with a connecting block. The connecting block is fixedly connected with the tube plug. Preferably, the tube plug is made of rubber material. The connecting block and the connecting end of the foot wire are rubber-coated inside the connecting block. The end of the connecting block connected with the tube plug is provided with two welding feet connected with the foot wire. The welding feet are covered inside the tube plug.

[0007] Further, the middle end of the plug hole is provided with an inner shrinkage hole with a smaller diameter than the plug hole. The position of the inner shrinkage hole is flush with the position between the two inner grooves. The plug rod cooperates with the inner shrinkage hole to extrude the tube plug at the position of the inner shrinkage hole, causing deformation. The deformation makes the tube plug protrude outward at this position, thereby forming a more tightly close contact structure with the inner wall of the tube shell between the two inner grooves, avoiding loosening of the tube plug.

[0008] Further, the side surface of the connecting block is provided with protruding reinforcing blocks, the number of the reinforcing blocks is multiple, and the connection firmness between the electric control module and the pipe plug is strengthened.

[0009] Further, the shapes of the plug block and the plug groove are both fan-shaped structures, the number of both is two, the two plug grooves are symmetrically distributed on the pipe plug, and the plug block and the plug groove can form a complete pipe plug structure after cooperation.

[0010] Further, the inner groove is a circular arc groove, and the circular arc groove can effectively position the pipe plug.

[0011] In conclusion, the utility model has the following beneficial effects: the utility model discloses a plug hole and a plug rod structure on the pipe plug, which can effectively balance the air pressure inside and outside the detonator during installation, and the structure can form a tight connection structure, thereby improving the connection reliability of the pipe plug and the pipe shell.
