Description

Technical Field

[0001] This utility model belongs to the field of unit pyrotechnics, specifically relating to a single-leg twisted transducer element, which is mainly used in missile gyroscope systems for gyroscope initiation ignition and other technical fields. Background Technology

[0002] Traditional electro-pyrotechnic components consist of two or more leads. When assembled into a missile gyroscope system, these leads often break after ignition, leading to poor reliability and failing to meet the operational requirements of high-speed gyroscope rotor rotation for normal gyroscope operation. To improve the safety and reliability of artillery-launched missiles, an innovative design was implemented for the pyrotechnic components used in gyroscopes. Through research, a single-lead torsion-break transducer element was designed, solving key technical challenges such as high pressure resistance, vacuum ignition, lead breakage prevention, high environmental adaptability, and reliable ignition. This ensures the safety, reliability, environmental adaptability, and manufacturability of the weapon system. Utility Model Content

[0003] The purpose of this invention is to provide a single-leg torsion-break transducer element, the specific technical solution of which is as follows:

[0004] A single-leg torsion-break transducer element comprises an electrode plug, a housing, a fixing adhesive, solder, and bridge wires. The electrode plug consists of a lead wire, an outer electrode, and an insulator. The insulator covers the outer surface of the lead wire, and the outer electrode is embedded in the left end of the insulator. The lead wire and the outer electrode are integrally molded by compression molding. The outer electrode of the electrode plug is coated with solder, and the insulator on the conical surface of the electrode plug is coated with fixing adhesive. The electrode plug is then installed into the housing for sealing. Two bridge wires are respectively soldered to the left lead wire and the outer electrode of the electrode plug.

[0005] Furthermore, the electrode plug adopts a single lead wire structure, and a torque weak point is designed at the right end of the lead wire 3mm away.

[0006] Furthermore, the electrode plug and bridge wire adopt a dual-bridge parallel firing structure.

[0007] Furthermore, the output end on the left side of the housing is U-shaped, the input end on the right side is conical, and the right end of the housing has an external thread for installation at the gyroscope rotor interface position; the middle position of the outer side of the housing is machined into a hexagonal surface.

[0008] After assembly, the product meets the technical requirements of 700mA ignition, 35MPa output pressure resistance, lead wire breakage of 3.92N·cm, 59kPa vacuum ignition, damp heat resistance, medium pressure resistance, electromagnetic compatibility, and ignition reliability of 0.999.

[0009] Operation process: After the transducer element is filled with the detonating explosive, it forms an ignition unit. It is installed in the gyroscope of various types of artillery-launched missiles. When the product receives input energy, the transducer element converts electrical energy into heat energy, ignites the detonating explosive to form ignition energy, and through the combustion and transfer of the agent sequence in the product structure, ignites the gyroscope's explosive ring, generating high-pressure gas to drive the gyroscope rotor to rotate and reliably break the lead wire, achieving the purpose of high-speed rotation unlocking and realizing the normal operation of the gyroscope system.
