Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of warheads, and in particular relates to a warhead wire component structure. Background Art
[0002] A fuze is a control device that uses target and environmental information to detonate the warhead charge under predetermined conditions. Different fuzes are selected based on the type of ammunition and the target being engaged.
[0003] Some fuzes are divided into two parts, a head fuze and a base fuze, depending on the warhead design. In this case, a wire must pass through the warhead to connect the head and base of the fuze for signal transmission. Previously, a common method for routing wires was to mill grooves in the warhead charge to reserve space for the wires. However, as the power of explosive charges has increased, their sensitivity has also increased, making milling grooves inside the warhead charge more difficult and dangerous. Therefore, there is an urgent need to design a warhead wire structure that can connect the head and base of the fuze without milling grooves inside the warhead charge, thereby completing detonation.

[0023] In order to make the purpose, content, and advantages of the present invention more clear, the specific implementation methods of the present invention are further described in detail below with reference to the accompanying drawings and embodiments.
[0024] The design concept for the warhead conductor assembly in this utility model is as follows: To allow the conductors to pass through the warhead without milling grooves, the conductors must occupy minimal space. Therefore, this utility model considers a flattened conductor assembly, routing the conductors close to the interior of the warhead housing. Furthermore, a wiring tray is designed to connect to the flat cable, which is then connected to the fuze head and base to achieve signal transmission.
[0025] In the warhead wire assembly structure of the present invention designed based on the above ideas, the wiring tray is connected to both ends of the flat cable by thermoplastic pressing. The structural design of the wiring tray is as follows: Figure 1 As shown, the flat cable structure is shown in Figure 2 .
[0026] like Figure 1 As shown, the front side (II area) of the terminal block is covered with copper with a thickness of 0.035mm, and a solder resist insulation layer is applied to the entire back side; symmetrical screw holes are opened on both sides of the terminal block (for fixing with other parts), a small hole 1 is opened in the middle position, and tin solder is plated in the small hole 1. The small hole is used to connect with other parts to achieve the conduction function, and a slot 2 is opened in the middle position of the front side of the terminal block (the position of the small hole attachment), and tin solder is plated in the slot 2. Figure 1 The middle I area is not plated with solder;
[0027] like Figure 2 As shown, in order to ensure the strength of the cable, the flat cable is made of polynitrosamine material, the adhesive coating is 3M468MP, and the surface is covered with protective tape.
[0028] like Figure 3 As shown, the wire assembly is attached to the inside of the warhead shell to achieve conduction. The specific assembly and performance test steps are as follows:
[0029] S1. Attach the wire assembly to the inner wall of the housing (area III is the area coated with 3M468MP (surface protective tape));
[0030] S2. Measure the conductive performance of the wire assembly to see if it meets the requirements. If the resistance is not greater than 5Ω, it is considered to meet the requirements. Measure the insulation resistance of the wire assembly under a DC voltage of 500V. If the insulation resistance is greater than 100MΩ, it is considered to meet the requirements.
[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
