Abstract

The invention belongs to the technical field of signal transmission elements, and particularly provides an integrated subminiature coupler. The coupler mainly comprises a protective sleeve, a bus, a sub-line, a shell and a circuit board assembly. According to the coupler, the chip resistors are used for replacing metal film resistors, the overall layout of the circuit board assembly is optimized by changing the positions of the resistors corresponding to the bonding pads, and the circuit board manufacturing process is optimized, so that the length and the height of the circuit board assembly are greatly reduced; the sealing effect is achieved by filling the sealant at the joint of the protective sleeve and the cable after thermal shrinkage, and the length of the protective sleeve is greatly shortened. The impact resistance and the vibration resistance of the component are improved in a manner of filling and sealing the gap between the inner wall of the shell and the circuit board assembly; and by assembling the heat insulation gasket, the temperature resistance of the component is improved.

Description

technical field [0001] The invention belongs to the technical field of signal transmission components, and in particular provides an integrated ultra-miniature coupler. Background technique [0002] With the development of science and technology and the opening of the air transport market, the functions of aircraft onboard systems are becoming more and more comprehensive, and the functions of airborne systems are gradually increasing with the demand, which leads to the increase of related equipment for airborne systems. However, the internal space of the airframe is limited, and there are strict requirements on the weight of components. In order to increase the functions and equipment of aircraft onboard systems without affecting the flight performance of the aircraft, the integration and miniaturization of component products have become the general direction of market development. [0003] The data bus coupler is a component used in a large amount in the airborne system. Cu...
