[0002] A fuze, also known as a fuse, is a detonation device mounted on explosives. It is a control device (system) that uses target and environmental information to detonate or ignite the warhead charge of an munition under predetermined conditions. Fuzes can be broadly classified into mechanical and electronic types based on their structure. They can also be classified by their mode of action, such as time-activated fuzes, contact fuzes, proximity fuzes, and composite fuzes. Currently, contact fuze devices have some problems. Existing devices cannot guarantee successful triggering before use. Furthermore, their triggering methods are relatively simple, their applicable environments are limited, and they are prone to false triggering.

The upper housing 61 is connected to the upper part of the sliding track plate 18, and the lower housing 62 is connected to the lower part, and the connection is fixed by screws. One end of the second pressure rod 12 is threaded to the first pressure rod 11, and the other end is connected to the connecting rope 17. One end of the connecting rope 17 is fixedly connected to the first pressure rod 11. The wire storage knob 16 has one end that passes through the wire hole on the second pressure rod 12 and is connected to the rotating part of the wire storage knob 16. A full copper spring 13 is fitted onto the second pressure rod 12, with one end abutting against the limiting hole on the sliding track plate 18 and the other end abutting against the limiting post of the second pressure rod 12. A fixing block 14 is also included, mounted on the sliding track plate 18, limiting the second pressure rod 12. A movable copper tube 15, perpendicular to the second pressure rod 12, is installed on the second pressure rod 12. Based on this trigger module design, the following advantages are achieved:
[0036] Compact structure: The trigger module 1 achieves a compact design by integrating multiple components (first pressure rod 11, second pressure rod 12, etc.) into one module, which facilitates installation and transportation.
[0037] Flexible operation: The second pressure rod 12 can slide on the sliding track plate 18, providing a flexible operation method and allowing users to adjust the position of the pressure rod as needed.

When the action of Trigger Module 1 causes the moving copper tube 15 to contact the fixed copper tube, the circuit is turned on, and current flows through the electronic components on Circuit Board 28, such as the upper safety switch 23 and the lower safety switch 24, ensuring that accidental triggering is prevented during operation, especially during installation and maintenance, thus ensuring personnel safety. Verification switch 25 and verification indicator light 26 are used to detect the status of ignition resistor module 5, ensuring the reliability and safety of the device. Output female connector 27 connects to a 3P terminal wire, which in turn connects to power indicator light module 4, providing a visual indication of the circuit status.
[0094] Power indicator module 4: Power indicator module 4 is connected to the output female terminal 27 of circuit board module 2 via a 3P terminal wire 41. When the circuit is on, current flows through the 3P terminal wire 41, the first connecting wire 42, and the second connecting wire 43 to the 2P terminal wire female terminal 45, and then through the first connecting wire 42 and the third connecting wire 44 to the power indicator 46, causing it to light up and display the circuit status. This module provides intuitive visual feedback, allowing users to immediately know whether the circuit is on, thereby determining whether the fuse is ready.
[0095] Ignition resistor module 5: Ignition resistor module 5 is connected to the 2P terminal female connector 45 of power indicator module 4 via 2P terminal wire 51, forming a circuit loop. When current flows through ignition resistor 52, heat is generated due to the resistance, which is a crucial step in the ignition of the fuse triggering device. Simultaneously, the test is activated by verification switch 25, and verification indicator 26 displays the status of ignition resistor 52, ensuring the device is in good working order before actual use.
[0096] Power module 3: Power module 3 consists of battery 31 and battery base 32. Battery base 32 is connected to circuit board 28 in circuit board module 2 via wires to provide the necessary power to the entire device. Battery 31 serves as the energy source, ensuring that circuit board module 2 and other electronic components can function properly and realize the electronic ignition process of the fuse.
[0097] Housing 6: Housing 6 consists of an upper housing 61, a side housing 62, a lower housing 63, and a pressure bar cover 64, protecting the trigger module 1, circuit board module 2, and power supply module 3 from external impacts, dust, and moisture. The housing design not only provides physical protection but also considers aesthetics and structural stability, ensuring the durability and reliability of the device.
[0098] Overall workflow:
[0099] The operator triggers the device by pressing the first pressure lever 11 or pulling the connecting rope 17, and the mechanical action of the trigger module 1 is converted into an electrical signal.
[0100] After receiving the electrical signal, the circuit board module 2 ensures safety through the upper safety switch 23 and the lower safety switch 24. The current flows through the power indicator 46 to detect the internal circuit status of the model. The current flows through the verification switch 25 and the verification indicator 26 to detect the status of the ignition resistor module 5.
[0101] If the internal circuit of the model is in good condition, the current flows through the output female connector 27 and the 3P terminal wire 41 to the power indicator module 4, and the power indicator 46 lights up. Then, the upper safety switch 23 and the lower safety switch 24 are turned on, and the resistor module 5 is connected. If the ignition resistor module 5 is in good condition, the verification switch is pressed, and the verification indicator lights up, indicating that the circuit is conducting.
[0102] If there are no problems with the entire circuit, turn off the upper fuse switch 23 and the lower fuse switch 24. The current will flow through the ignition resistor module 5 to generate heat, preparing for ignition.
