Embodiment Construction
[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0029] Such as figure 1 The schematic diagram of the electrical system of the aircraft shown includes a bracket base 10 and a motherboard 5; the bracket base 10 is circular, with motherboard fixing positions on the edge, and several protrusions for fixing the bracket are evenly distributed on the edge , The protruding part is provided with round holes for bolt fixing. The motherboard 5 is fixed at the corresponding position between the two bracket bases 10 through the motherboard fixing position. The motherboard 5 is provided with an inter-board connector interface for connecting circuit boards through the inter-board connector 2 . The support base 10 is made of aluminum.
[0030] Such as figure 1 As shown, the motherboard 5 , the circuit board 6 , the circuit board 7 , the circuit board 8 and the circuit board 9 are arranged on a plane parallel to the ax...

The invention relates to an aircraft and an electrical system thereof. The system comprises aluminum support bases, a mother board and circuit board assemblies, wherein the mother board and the circuit boards are fixed between the two support bases. The reliable electrical connection between the circuit boards and between the circuit boards and the mother board is achieved through inter-board connectors, and the two ends of the mother board are connected with upstream and downstream circuits through cables. The system is stable in structure and high in modularization degree, the manufacturability of the device product is improved, the weight of the device product is reduced, the production and manufacturing cost is reduced, the device is easy to overhaul, the operation and maintenance burden is reduced, and the problem that high-speed signal transmission cannot be accurately controlled is solved. Moreover, there is a gap between every two plates, thereby facilitating the planning of aheat dissipation air path, and effectively solving the heat dissipation problem.
Description
technical field [0001] The invention relates to an aircraft and its electrical system, belonging to the electrical field. Background technique [0002] A kind of aircraft, its trunk is cylindrical, its electrical connections are all located in the middle of the barrel-shaped main body, the components at the front end of the main body include power supply components, telemetry components, etc., and the components at the rear end are power components. [0003] The electrical components of the aircraft are independently constituted structurally, generally in the form of a main cable, with one or several connecting cables organically connecting the electrical components together to form a whole, so that each functional component can work in accordance with the corresponding working sequence and control Logic completes the exchange and transmission of electrical signals. Due to the weight and volume of the main cable; the processing and production of the main cable requires a lo...
