Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0033] Such as figure 1 As shown, the chassis is composed of a front panel 1, a housing part 2, an upper cover 3 and a lower bottom plate 4, wherein the housing part 2 is as figure 2 As shown, it is made up of left side plate 5, dividing plate 6, rear panel 7 and right side plate 8. Among them, there are grooves on the inner surface of the left side plate 5 and the right side plate 8, and vacuum brazing solder is placed in the grooves, the partition plate 6 is inserted into the grooves, fixed with screws, and the rear panel 7 is respectively connected to the left and right side plates Fix with screws after adding solder. After fixing, put the shell part 2 into a vacuum brazing furnace for welding, and after the welding is completed, retighten the screws to enhance the fixing effect.

Abstract

The invention relates to a brazed sealed machine box having an internal support and used for an ocean environment. The brazed sealed machine box is composed of a front panel (1), a shell part (2), anupper cover plate (3) and a lower bottom plate (4). According to the vacuum brazed sealed machine box, a tool clamp does not need to be customized for welding, so that the production period is shortened, the production cost is reduced, and the product assembly process performance and the sealing performance required by the ocean environment can be met.

Description

technical field [0001] The invention belongs to the field of aviation power distribution systems, and relates to a sealed box for power system products, which is a brazed sealed box with internal support for marine environments. Background technique [0002] Usually, the chassis of power distribution products is welded on three sides, and it is necessary to make fixtures to ensure the welding quality, which takes a long cycle and high cost. In order to ensure the welding quality, four sides of the chassis are welded, which increases the difficulty of assembling the circuit board. [0003] From the perspective of sealing, if the four sides of the chassis are connected by fasteners, gaps must be left on the overlapping surfaces and screw holes, and the electromagnetic compatibility and three-proof performance of the product cannot be guaranteed. [0004] General-purpose electronic chassis mostly use external reinforcement of the panel to increase strength, but due to the requ...
