Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic detonator technology, and in particular to an integrated end-piece structure that can be used in wireless electronic detonators. Background Technology
[0002] When in use, the terminals of a wireless electronic detonator are located at the tail of the digital electronic detonator control module for connecting to the busbar; when the terminals are located in the middle of the digital electronic detonator control module, they are used to protect the control module and are equivalent to the ground wire.
[0003] However, regardless of where it is used, there will be interference and static electricity, which can damage the circuit.
[0004] In view of this, there is an urgent need for an integrated end-piece structure that can be used in wireless electronic detonators. Utility Model Content
[0005] The purpose of this invention is to provide an integrated end-piece structure for use in wireless electronic detonators, thereby solving the aforementioned technical problems.
[0006] An integrated tip plate structure for use in wireless electronic detonators includes:
[0007] The first terminal and the second terminal are connected by an insulating adhesive block;
[0008] The end bullet includes a fixed end and a free end. The fixed end is embedded in the insulating rubber block, and the free end extends outward. When the first terminal and the second terminal are partially placed inside the tube shell, the free end abuts against the inner wall of the tube shell to limit the first terminal and the second terminal, and can also conduct static electricity through the inner wall of the tube shell.
[0009] In some possible implementations, the insulating block is located on one side of the first terminal and the second terminal, and the first terminal and the second terminal are fixed by the insulating block.
[0010] In some possible implementations, the middle portion of the end bullet is bent so that the free end is perpendicular to the first terminal and the second terminal.
[0011] In some possible implementations, the end of the free end is bent back.
[0012] In some possible implementations, the middle portion of the free end is bent at an angle toward the first and second terminals.
[0013] In some possible implementations, the middle portion of the fixed end is embedded within the insulating rubber block.
[0014] In some possible implementations, the middle portion of the fixed end is continuously bent within the insulating rubber block to form a U-shape.
[0015] In some possible implementations, the end of the fixed end extends beyond the insulating rubber block.
[0016] In some possible implementations, the portion of the fixed end extending out of the insulating block is used for welding.
[0017] In some possible implementations, the ends of the first and second terminals furthest from the insulating block form an acute angle with the middle of the first and second terminals.
[0018] The beneficial effects of this utility model are as follows: This utility model provides an integrated end-piece spring sheet structure for use in wireless electronic detonators, including a first terminal and a second terminal, connected by an insulating adhesive block. The end-piece spring sheet includes a fixed end and a free end, the fixed end being embedded in the insulating adhesive block, and the free end extending outward. When the first and second terminals are partially placed inside the casing, the free end abuts against the inner wall of the casing to limit the movement of the first and second terminals and to conduct static electricity through the inner wall of the casing. This structure integrates the two terminals and the spring sheet with insulating adhesive, achieving not only anti-interference, anti-static, and circuit protection, but also saving materials and costs, reducing welding times, saving space on the wireless electronic detonator, and allowing compatibility with other functional devices in more control modules.

[0031] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components.

[0034] like Figures 1 to 5 As shown, Figure 5 The middle arrow indicates the direction of movement of an integrated end-piece clip structure that can be used in wireless electronic detonators. This invention provides an integrated end-piece clip structure that can be used in wireless electronic detonators, comprising a first terminal 1, a second terminal 2, an insulating block 3, and an end-piece clip 4.
[0035] The first terminal 1 and the second terminal 2 are connected by an insulating block 3. Specifically, the insulating block 3 is located on one side of the first terminal 1 and the second terminal 2, and the first terminal 1 and the second terminal 2 are fixed by the insulating block 3. In this way, while the insulating block 3 is fixed to the first terminal 1 and the second terminal 2, it does not affect the welding in the middle of the first terminal 1 and the second terminal 2, that is, the welding on the side away from the insulating block 3.
[0036] The bullet-shaped piece 4 includes a fixed end 41 and a free end 42. The fixed end 41 is embedded in the insulating rubber block 3, and the free end 42 extends outward. When the first terminal 1 and the second terminal 2 are partially placed inside the tube shell 5, the free end 42 abuts against the inner wall of the tube shell 5 to limit the first terminal 1 and the second terminal 2, and can also conduct static electricity through the inner wall of the tube shell 5.
[0037] It should be noted that the free end 42 is located on one side of the insulating block 3. This saves space in the middle of the first terminal 1 and the second terminal 2. In other words, if the existing first terminal 1 and the second terminal 2 are respectively located at the tail of the control module of the wireless electronic detonator, and the end bullet piece 4 is located in the middle of the control module of the wireless electronic detonator, the control module of the wireless electronic detonator itself is small in size. If an additional bullet piece is added, it will occupy the space of the control module of the wireless electronic detonator. Therefore, by arranging the end bullet piece 4 at one end of the first terminal 1 and the second terminal 2, not only is space saved on the wireless electronic detonator, but it can also be compatible with other functional devices of the control module.
[0038] It should also be noted that since the first terminal 1 and the second terminal 2 are connected to the busbar and the digital electronic detonator control module, interference and static electricity will be generated, which may damage the circuit. Therefore, after the end bullet piece 4 abuts against the inner wall of the tube shell 5, it can act as a conductor to conduct static electricity, thereby achieving the functions of anti-interference, anti-static and circuit protection.
[0039] In one embodiment, the end of the free end 42 is bent back. For example, it is bent back 180 degrees, which increases the strength of the free end 42.
[0040] In one embodiment, the middle portion of the end clip 4 is bent so that the free end 42 is perpendicular to the first terminal 1 and the second terminal 2. For example, the middle portion of the end clip 4 is at a 90-degree angle. This allows the free end 42 to enter the tube shell 5 first, and simultaneously abut against the inner wall of the free body, thus protecting and limiting the first terminal 1 and the second terminal 2.
[0041] In one embodiment, the middle portion of the free end 42 is bent at an angle toward the first terminal 1 and the second terminal 2. This effectively increases the elasticity after entering the casing 5, i.e., increases the force exerted by the free end 42 on the inner wall of the casing 5, thereby improving stability.
[0042] In one embodiment, the middle portion of the fixing end 41 is embedded within the insulating rubber block 3, and the middle portion of the fixing end 41 is continuously bent within the insulating rubber block 3 to form a U-shape. This inverted U-shaped structure increases the contact area between the middle portion of the fixing end 41 and the insulating rubber, thereby increasing the overall stability of the end bullet piece 4.
[0043] In one embodiment, the end of the fixing end 41 extends beyond the insulating block 3. The portion of the fixing end 41 extending beyond the insulating block 3 is used for soldering. This allows the fixing end 41 to be soldered to a circuit board or related wiring to eliminate interference and static electricity in the circuit board or wiring.
[0044] In one embodiment, the ends of the first terminal 1 and the second terminal 2 furthest from the insulating block 3 form an acute angle with the middle of the first terminal 1 and the second terminal 2. This causes the tails of the first terminal 1 and the second terminal 2 to slightly lift off the riveting portion, thus offsetting them from the PCB board and disrupting the capillary effect of the flux, solving the problem of flux contaminating the terminals.
[0045] In summary, this utility model provides an integrated terminal bullet sheet structure that can be used in wireless electronic detonators. When the terminal and the terminal bullet sheet 4 are integrated, it means that the two terminals and the terminal bullet sheet 4 are fused together with insulating glue, which can play a role in anti-interference, anti-static and circuit protection.
[0046] The advantages of integration are: saving materials and reducing costs; reducing the number of welding operations, as the terminals and springs originally needed to be welded separately, but now only one welding operation is required after integration; more importantly, the integration of the terminal spring 4 and the terminal saves space on the wireless electronic detonator control module and can accommodate other functional components of more control modules.
[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
