Problems solved by technology

[0003] Because the marine environment has higher requirements on the weight and environmental adaptability of airborne equipment than ordinary military aircraft, ordinary military aircraft airborne equipment cannot meet the technical requirements of this system in these two aspects
Ordinary military aircraft airborne equipment generally adopts the structure of riveting and splicing of cover plates. The overall weight is heavy and the assembly is more complicated. The dimensional accuracy is poor. At the same time, the environmental adaptability is insufficient. Insufficient shock protection for cards

Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with examples, but the embodiments of the present invention are not limited thereto.

[0033] In this embodiment, the terms "front", "rear", "left", "right", "inner" and "outer" are all used with reference to figure 1 The coordinate axes of are used for convenience of description.

[0034] Such as figure 1 As shown in -4, a mechanical casing for voice transmission equipment used on aircraft, wherein the upper cover 4, the heat dissipation cover 9, the lower cover 10, the left cover 2, and the light guide plate 1 are respectively above, right, and below the frame body 3 , the left side and the front side, through the screws corresponding to the number of screw holes on each cover plate, the thread on the frame body 3 is used for locking connection. The PCB board 5 is connected and fixed on the frame body 3 by using the locking block assembly 6, and is connected to the corresponding connector...

Abstract

The invention discloses a mechanical shell of voice transmission equipment arranged on an aircraft. The mechanical shell of the voice transmission equipment comprises a light guide plate (1), a left cover (2), a frame body (3), an upper cover (4), a PCB (printed circuit board) (5), a locking block assembly (6), a connector (7), a bottom plate (8), a heat dissipation cover (9) and a lower cover (10). The mechanical shell of the voice transmission equipment is of a frame structure, and the size of each frame column is a minimum size after screws are connected with a required space. In this way,the weight of the mechanical shell of the voice transmission equipment is as low as possible. All cover plates are connected to the frame through screws to realize the closed state of the mechanical shell, so that the requirement on the environment of the sea is met. The locking block assembly is provided with a stressed part and a pulling-out supporting point which can be used for pulling out. Asa result, the easy maintainability and the vibration resistance of a board card during the pulling-out and inserting process are ensured.

Description

technical field [0001] The invention relates to a voice transmission device on an aircraft, in particular to an external mechanical structure for a voice transmission device on a fixed-wing aircraft carried by a ship. Background technique [0002] The voice transmission equipment on the fixed-wing aircraft carried by the ship is used in the maritime environment. It is the audio processing center of the aircraft. It is mainly used for in-flight calls between on-board members and communication between on-board members and external radio stations. The sea environment is harsher than that on land, and the requirements for weight and environmental adaptability of fixed-wing aircraft are higher. [0003] Because the marine environment has higher requirements on the weight and environmental adaptability of airborne equipment than ordinary military aircraft, ordinary military aircraft airborne equipment cannot meet the technical requirements of this system in these two aspects. Ord...
