Image intensifier power supply potting device and potting method

Abstract

The invention discloses an image intensifier power supply potting device and a potting method, and belongs to the technical field of image intensifiers. According to the image intensifier power supplypotting device and the potting method, effective operation of a potting process can be realized, and the potting quality problems can be reduced. According to the technical scheme, the device comprises a base assembly, a gasket, an outer cylinder, a pressing plate and a nut; the base assembly is of an integrated part composed of a plurality of cylindrical functional steps, and the cylindrical functional steps comprise a gasket supporting column, an outer cylinder fixing column, an outgoing line guiding column, a power supply fixing column, a pressing plate fixing column and a screw rod whichare sequentially decreased in diameter from bottom to top; a through wire groove is formed in the outer cylinder fixing column, the gasket sleeves the bottom of the outer cylinder fixing column, the lower part of the outer cylinder sleeves the upper part of the outer cylinder fixing column, and the top surface of the outer cylinder and the top surface of the power supply fixing column are locatedon the same horizontal plane; and a gap used for installing the power supply is reserved between the upper part of the outer cylinder and the power supply fixing column, the pressing plate sleeves thepressing plate fixing column, and the nut is in threaded connection with the top of the screw rod and compress the pressing plate.

Description

technical field [0001] The invention relates to an image intensifier power supply potting device and a potting method, which belong to the technical field of image intensifiers, and in particular to an image intensifier power potting device and a potting method. Background technique [0002] The image intensifier is an important imaging device in the field of low-light night vision, and has significant uses in military, scientific research and other fields. The image intensifier power supply is a DC / DC power conversion device for the image intensifier, which consists of four parts: a power supply circuit board, a casing, a cover plate, and a lead wire. According to different application requirements, image intensifiers are divided into various dimensions, among which 16mm image intensifiers, 18mm image intensifiers, and 40mm image intensifiers are commonly used. Similarly, power supplies are also divided into 16mm power supplies, 18mm power supplies, 40mm power supplies, etc...

AI Technical Summary

Problems solved by technology

[0005] 1. The original device does not have the protection function of the power supply shell. The stress generated during the curing process of the potting glue is likely to cause lateral deformation of the shell, and even cause the shell to break, so that the shape and structure of the power supply are damaged and cannot be used any longer.

[0006] 2. The pressure plate in the original device only plays the role of vertically fixing the cover plate of the power supply. It cannot accurately locate the position of the cover plate, and it is easy to cause the cover plate to shift laterally, and the cover plate is crooked, which affects the outer diameter and height of the power supply. The size is out of tolerance and cannot be assembled on the image intensifier

[0007] 3. Since the device has no power cover positioning function, the cover plate is easily separated from other parts of the power supply during the potting process, so that the shape and structure of the power supply are damaged and cannot be used any longer.

[0008] 4. If the original device is used for potting, the reliability and consistency of the power supply cannot be guaranteed, and the production efficiency and yield rate of the power supply cannot be improved.
