Direct insertion type box structure of control board on top of aircraft cockpit

Abstract

The invention provides a direct insertion type box structure of a control board on the top of an aircraft cockpit. The direct insertion type box structure comprises a control panel assembly, a bus board assembly, a large box and guiding structures, wherein the bus board assembly is arranged on the large box; the control panel assembly comprises at least one control panel; and the control panels are connected with the bus board assembly through the guiding structures and a board-to-bard connector. No electric module or independent electromagnetic shielding back cover is arranged on each control panel any more respectively, and the electric modules are arranged on bus boards to form the bus board assembly. Each control panel is electrically connected with board-to-board connector sockets on the bus boards through board-to-board connector plugs. The control panels realize blind insertion of the board-to-board connectors through the guiding structures, and then are fixed on the large box through quick-release fasteners. Small wiring harnesses on intermediate connectors matched with connectors on the back of the bus boards are merged into a relatively large wiring harness, and are concentrated on a circular connector on the large box, so that connection with the outside is established through the circular connector.

Description

technical field [0001] The invention relates to a box structure, in particular to an in-line box structure for a control panel on the top of an aircraft cockpit. Background technique [0002] At present, domestic aircraft cockpit top control panel products (see figure 1 ) in the form of a structural frame 2' and a control panel assembly (comprising a plurality of control panels 11'), each of which has an electrical interface and a mechanical interface with the aircraft. The top control panel control panel assembly is installed on the frame structure 2', and is electrically connected with each other by cables 3'. Such frame structures and control panel assemblies have the following disadvantages: [0003] (1) Complex manufacturing: each control panel has an electromagnetic shielding rear cover 114', a circular connector 115', a metal base plate 117' and an electrical module 118', etc. (see figure 2 ), it can be seen that there are many parts to be installed, high manufact...

AI Technical Summary

Problems solved by technology

[0003] (1) Complex manufacturing: each control panel has an electromagnetic shielding rear cover 114', a circular connector 115', a metal base plate 117' and an electrical module 118', etc. (see figure 2 ), it can be seen that there are many parts to be installed, high manufacturing cost and heavy weight;

[0004] (2) Inconvenient maintenance: In addition to loosening (fastening) the mechanical fixing parts of the control panel, it is also necessary to unplug or plug in the 3' plug of the control panel cable during maintenance, which takes time to disassemble;

[0005] (3) Cable laying is difficult: After the control panel components are installed in the frame structure 2', the internal wiring of the top control board is carried out according to the electrical interface of each control panel. Affected by the operating environment and installation space, the cable laying Time-consuming;
