Isolation transformer for MIL-STD-1553B

Abstract

The invention belongs to the technical field of structures of isolation transformers, and discloses an isolation transformer for an MIL-STD-1553B. The isolation transformer for the MIL-STD-1553B comprises a shell, multiple leading pins extending from the shell and a pulse transformer arranged in the shell, wherein coil leads of the pulse transformer and corresponding leading pins are welded together, a pure nickel cover plate is fixed at the upper end of the shell in a sealed mode, and the shell and the leading pins are made of kovar alloy.

Description

Technical field [0001] The invention belongs to the technical field of isolation transformer structures, and particularly relates to an isolation transformer for MIL-STD-1553B bus. The isolation transformer is a communication interface transformer, which can be specifically used as an isolation transformer for a 1553B bus hardware system, and is used between the 1553B protocol processor and the system bus. Background technique [0002] The 1553B bus standard is called the MIL-STD-1553B bus standard, which was implemented in early 1968. On September 21, 1978, after obtaining formal written approval, the MIL-STD-1553B bus standard was published as an official document of the United States. The MIL-STD-1553B bus was originally the standard bus of the American avionics integrated system. It was used to provide a medium for the exchange of data and information between various systems. Its role is similar to that of "Local Area Network or LAN". MIL-STD- The 1553B bus has been widely ...

AI Technical Summary

Problems solved by technology

At present, the isolation transformers used for 1553B bus are all plastic-encapsulated devices, which cannot meet the requirements of 48-hour salt spray test, storage and service life in special fields, and the pass rate of products is low during the filling process.
