Airtight small-winding-moment wire shaft penetrating device

Abstract

The invention discloses an airtight small-wire winding moment wire shaft penetrating device which comprises a first wire shaft penetrating module installed in an inner cavity of a pitch shaft system and a second wire shaft penetrating module installed in an inner cavity of an azimuth shaft system, the pitch shaft system is structurally connected with a photoelectric pod bridge and an optical cabin, and the azimuth shaft system is structurally connected with the optical cabin and an electronic cabin. The first wire shaft penetrating module comprises an inner wire passing plate and an outer wire passing plate, and a first wire penetrates through the inner wire passing plate and the outer wire passing plate. The second wire shaft penetrating module comprises a wire penetrating support and a wire bunching plate, a second wire penetrates through the wire penetrating support, and the end of the second wire is fixed to the wire bunching plate. According to the invention, the defects of large volume and heavy weight of a signal transmission cross-linking mode at the shafting of the small photoelectric pod are overcome, and the use is simple and light.

Description

Technical field [0001] The present invention belongs to the field of small photoelectric pod wiring technology, relates to an optical pod---- especially an airborne or small unmanned aerial vehicle carrier photoelectric pod of an airtight, small wire winding moment wire through the shaft device. Background [0002] With the increase in the market demand for small photoelectric pods, the technological development in related fields at home and abroad is quite rapid, and the miniaturization, high integration and light engineering of small photoelectric pods are inevitable trends. [0003] Due to the small structure size, high integration (composed of a variety of sensors, circuit boards, etc.), the variety of signals and complex crosslinking, the small photoelectric pod has brought great difficulties to the layout of the internal wires, especially in the azimuth / roll shaft system cavity and the pitch shaft system cavity. [0004] The photoelectric pod often has sealing requirements ...
