The invention relates to a universal aircraft electrical system bus bar device convenient to expand. The device comprises an insulating support arranged on the base, bus bars fixed to the insulating support, an amplitude limiting rod support arranged on one side of the insulating support, an amplitude limiting rod arranged on the amplitude limiting rod support, a wiring terminal connected to the amplitude limiting rod, and two ends of the fuse connected with the bus bar and the wiring terminal respectively. When in use, the bus bars are fixed on the insulating support, the insulating support is fixed on the base through rivets, the bus bars are insulated from one another and are convenient to install, the bus bars are provided with the shell, and the shell are provided with wiring holes, so that wiring adjustment can be performed as required. The length of the bus bars can be expanded according to needs, only the installation position of the insulation support needs to be adjusted, the expansion performance is good, and use and maintenance are convenient.
Description
technical field [0001] The invention belongs to the field of aircraft electrical systems, in particular to a general-purpose aircraft electrical system bus bar device that is easy to expand. Background technique [0002] The addition of electrical system bus bars to an aircraft needs to be installed at a suitable location on the aircraft. The existing bus bars are usually directly connected to the body of the aircraft instrument panel. Although the reliability of this connection is high, it cannot be expanded and adjusted according to actual needs due to the fixed length. In the design of a certain type of aircraft, because there are many devices connected to the bus bar, it needs to be expanded during the development process. After using the existing bus bar to complete the design, the scalability is poor, and it cannot meet the requirements for the installation and use of aircraft equipment cables. Contents of the invention [0003] The technical problem to be solved b...
