Abstract

The invention discloses a fixing device. The fixing device is used for fixing a light guide post module on a shell; both the light guide post module and the fixing device are arranged inside the shell; the light guide post module comprises light guide posts; light guide holes which are correspondingly matched with the light guide posts are formed in the shell in a penetrating manner; the fixing device comprises a sealing element and a pressing die; the sealing element is provided with first through holes; the light guide posts pass through the first through holes and the light guide holes in a matching way in order to conduct light emitted by an LED (Light-Emitting Diode) lamp out of the shell; the light guide post module comprises a limiting plate which is vertical to the length directions of the light guide posts; the sealing element is clamped and fixed between the limiting plate and the inner wall of the shell; and the pressing die is clamped on the inner wall of the shell, and is used for pressing the light guide post module and the sealing element against the inner wall of the shell. Through adoption of the fixing device, screw-free installation of the light guide post module on the shell is realized, and the problem of easiness in corrosion during installation of screws on the outer wall of the shell is solved, and the IP (INGRESS PROTECTION) grade of the shell is raised.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a fixing device. Background technique [0002] The light guide column is a component that guides the light emitted by the indicator light on the PCB (Printed Circuit Board, printed circuit board) to a preset light-emitting position. It has been widely used as a light transmission structure of the indicator light of communication equipment. [0003] One of the common installation methods of the light guide column is to screw the light guide column on the appearance surface of the product shell by screws. The disadvantage is that the screws have a great influence on the appearance of the product shell. Moreover, for outdoor products with waterproof requirements, the anti-corrosion, waterproof and reliability of the screws are relatively poor. [0004] For the existing aluminum die-casting shell, the installation method of the light guide column is that the surface of the light...
