Problems solved by technology

In most cases, a wire harness block that is separated from the box body will be set to reduce the difficulty of assembly, which results in discontinuous sealing of the flight control box itself at the wire harness block, and the connection between the wire harness block and the box body Additional sealing is also required, which complicates the structure of the entire flight control box

Embodiment 1

[0054] Such as figure 1 — Figure 9 As shown, a continuously sealed flight control box includes a box body and electronic and electrical components inside the box body. The box is a rectangular box, and the wire harness block 4 is a rectangular block as a whole. Threaded holes 16 are set on the surrounding wall 15 , countersunk holes 23 are set on the corresponding threaded holes on the bottom plate 2 , and bolts pass through the through holes to connect with the threaded holes, so that the upper cover 1 and the bottom plate 2 are tightly fastened.

[0055] The box body includes an upper cover 1, a wire harness block 4, a bottom plate 2 and a sealing strip 3; the upper cover 1 includes a top wall 14 and a surrounding wall 15 located below the top wall; a first groove 151 is provided on the lower end of the surrounding wall; The surrounding wall 15 is provided with a "冂"-shaped notch 11, and a chute 12 is provided on the surrounding wall where the "冂"-shaped notch 11 is set.

...

Embodiment 2

[0066] Such as Figure 10 As shown in -18, in this embodiment, a plurality of "冂"-shaped notches 11 are provided, although it should correspond to a plurality of wire harness blocks 4, but in this embodiment, a plurality of wire harness blocks 4 are combined to form a wire harness Block, five through holes 41 of the same size are set on the wire harness block 4 for the wire harness to pass through.

[0067] Here, hollow grooves 13 structures are provided in many places, which effectively reduces the quality.

[0068] The main difference between this and the above-mentioned embodiment is that the "冂"-shaped notch opened on the upper cover is slightly different. In order to cooperate with the wire harness block, the chute of the two adjacent notches communicates, which can greatly reduce the manufacturing difficulty and improve the assembly efficiency. .

Abstract

The invention discloses a continuously-sealed flight control box, and the box comprises a box body and electronic and electrical components in the box body. The box body comprises an upper cover, a bunching block, a bottom plate and a sealing strip; the upper cover comprises a top wall and a surrounding wall located below the top wall; a first groove is formed in the lower end surface of the enclosure wall; an n-shaped notch is formed in the surrounding wall, the wire block is a rubber block, the wire bundling block seals and blocks the notch, and the wire bundling block and the surrounding wall form an integrated structure; a through hole for a bunch to pass is formed in the bunching block; a receding groove is formed in the wire bundling block; the two ends of the receding groove are connected with the first grooves, so the sealing strips embedded into the first grooves are uninterrupted; when the upper cover and the bottom plate are buckled, continuous sealing is formed between theupper cover and the bottom plate. According to the invention, the existing design thinking is changed, the overall sealing effect of the box body is enhanced under the condition of simplifying the structure of the box body, and the waterproof and dustproof effects are effectively achieved no matter the bunch wire enters or exits or the upper cover and the bottom plate are sealed; the cost is low,assembling is easy, and production efficiency is improved.

Description

technical field [0001] The invention relates to the field of aircraft, in particular to a continuously sealed flight control box. Background technique [0002] The flight control box is used to carry the inertial measurement unit (used to adjust the state of the unmanned aircraft), which requires data exchange inside and outside the flight control box; therefore, it is necessary to open a through hole on the flight control box for data exchange beamline through. In most cases, a wire harness block that is separated from the box body will be set to reduce the difficulty of assembly, which results in discontinuous sealing of the flight control box itself at the wire harness block, and the connection between the wire harness block and the box body Additional sealing is also required, which complicates the structure of the entire flight control box. Contents of the invention [0003] The purpose of the present invention is to provide a continuously sealed flight control box,...
