Embodiment Construction

[0026] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0027] Such as figure 1 Shown is the interface form of the isolation transformer in the bus, figure 1 a is the direct coupling method, figure 1 b is the transformer coupling mode. The data transmitted on the 1553B bus is Manchester II type biphase level code, which is a set of pulse levels in standard format. The transmission principle is as follows: When the bus and the terminal are directly coupled, the bus signal enters through the 4-8 pins of the isolation transformer, and then enters the terminal through the 1-3 pins after passing through the isolation transformer; when the bus and the terminal adopt indirect coupling, The bus signal enters through the 5-7 pins of the isolation transformer, and enters the terminal through the 1-3 pins after passing through the isolation transformer.

[0028] Such as figure 2 Shown is a schematic diagra...

Abstract

The invention relates to a weather-proof isolation transformer with a metal full filling and sealing structure. The isolation transformer comprises a metal shell, a transformer coil, a bottom plate, a glue filling wall and an extraction rod. The extraction rod penetrates through the bottom plate to be fixed onto the bottom plate, one end of the extraction rod is connected with the transformer coil, the other end of the extraction rod is connected with an external device, the glue filling wall is fixedly connected to the edge of the bottom plate to form a filling and sealing space on the bottom plate, the filling and sealing space is filled with filling and sealing glue to fix the transformer coil, an opening at one end of the metal shell is sleeved on the glue filling wall, and an opening end of the metal shell is fixedly connected with the bottom plate to achieve a function of integral sealing. The isolation transformer has the advantages of high mechanical strength, more outstanding weatherproof performance, longer storage and service life, more excellent space adaptability and high electromagnetic compatibility.

Description

technical field [0001] The invention relates to an isolation transformer with an environment-resistant metal full potting structure, belonging to the technical field of low-power pulse transformers. Background technique [0002] The 1553B bus has become the dominant bus standard in the aerospace field, and has become the key to the interconnection of modern aviation airborne system equipment. It is widely used in aircraft, ships, tanks and other weapon platforms. The terminal equipment of the 1553B bus is connected to the bus through two connection methods, one is the direct coupling method, that is, the terminal is directly connected to the bus through a stub line; the other is the indirect coupling method, that is, the terminal is connected to the bus through a coupling transformer. In order to achieve short-circuit protection, DC isolation and impedance matching between the bus system and the terminal, no matter which coupling method is used between the terminal and the b...
