Example Embodiment

[0035] Example

[0036] A method of mounting high-power inductors for space, the steps are:

[0037] 1) The male mold for preparing the inductor, such as figure 1 As shown, the male mold includes a small cylinder at the upper part and a large cylinder at the lower part. The large cylinder and the small cylinder are coaxial cylinders. There is a positioning hole 1 in the center of one end of the small cylinder of the male mold, and the positioning hole 1 penetrates the small cylinder. Cylinder, and extend into the big cylinder;

[0038] 2) Use a plastic cup with a diameter of 90mm to define a boundary for the male mold, with the big end facing downward; potting silicone rubber on the male mold, pour the plastic cup with a height of 50mm, and completely submerge the male mold of the potting mold; Then solidify and shape;

[0039] 3) Use scissors to remove the plastic cup, take out the male mold of the potting mold, and modify the shape to make an elastic potting female mold, such as f...

Abstract

The invention relates to a spatial high-power inductor, and a preparation method and a mounting method of the inductor, and belongs to the technical field of satellite-borne power supplies. Mounting and fixing modes of the inductor are free from limitation of power, size and weight of the inductor; thermal resistance can be adjusted according to thermal loss of the inductor, that is, the thermal resistance of the inductor is changed by changing encapsulation height of a coil of the inductor, namely thickness of an encapsulation base and a contact area of the encapsulation base and a printed circuit board, so that the thermal loss of the high-power inductor is controlled accurately; a mounting base of the inductor is encapsulated by an epoxy resin material, so that stress of an enameled wire of the coil is avoided; an aluminum alloy embedded structural part is used for fixing and the periphery of the encapsulation base of the inductor is bonded by EC2216 glue, so that displacement in each direction of the inductor is limited; and the inductor is higher in reliability and good in mechanical property.

Description

technical field [0001] The invention relates to a high-power inductor for space and its preparation method and installation method, belonging to the field of on-board power supply technology, and relates to the low-voltage circuit self-made high-power inductor coil electronic assembly technology of the power supply part of the traveling wave tube amplifier. High-power inductors refer to inductors with a peak power of 1000W and an average power of 200-300W. Background technique [0002] The general inductor installation and fixing methods are as follows: dispensing glue fixing, binding wire binding fixing, pressing plate or sleeve fixing. Glue fixation is suitable for a single magnetic ring with a small size or two magnetic cores that are stacked and wound; the way of binding and fixing the binding wire is also limited by the size and weight of the self-made coil; coils with a diameter greater than Ф10 are preferably pressure plates or sleeves Fixing method, but when the wei...
