Description
Technical Field
The invention belongs to the technical field of wiring of small-sized photoelectric cabins, and relates to an airtight and small-wire winding rectangular wire shaft penetrating device for an optical cabins, in particular to an airborne or small-sized unmanned aerial vehicle photoelectric cabins.
Background
With the increase of market demands of small-sized photoelectric pods, the technology in the related fields at home and abroad is developing quite rapidly, and miniaturization, high integration, light weight and the like of the small-sized photoelectric pods are necessarily trends.
The small photoelectric pod has small structural size, high integration (composed of various sensors, circuit boards and the like), various signals and complex crosslinking, and brings great difficulty to the layout of internal wires, especially the problems at the two positions of the azimuth/horizontal rolling shaft system inner cavity and the pitching shaft system inner cavity.
The photoelectric pod has sealing requirement in the azimuth/transverse rolling shaft system cavity and pitching shaft system cavity, so that the signal crosslinking of the photoelectric pod in different parts of the shaft system cavity is realized by mainly selecting a converging ring or a wall-penetrating sealing socket. Whichever device is selected, the size of the bus ring or the sealing socket is determined according to the number and the type of the signals. However, under the existing technical conditions, the bus ring or the sealing socket has the defects of large size, heavy weight, high cost and the like. The small photoelectric pod with small structural size, light weight and complex electric circuit layout can not meet the use requirement.
