Description

Light guide fixing device

The invention relates to a light guide column fixing device.

The light guide column is generally a strip or column body, which has lower transmission loss and weight than other light source conduction devices, and is currently widely used in home appliances, electrical appliances and various 3C products. However, because the light guide column is light in weight, it is easy to sway after being installed in the casing of various products. In order to prevent the signal transmission effect from being shaken, it is usually fixed to the casing of the product by the adhesive, so that the light guide column is damaged. It is inconvenient to replace.

In view of this, it is necessary to provide a light guide column fixing device that is easy to disassemble.

A light guide column fixing device includes a housing of an electronic device, wherein the housing is oppositely provided with a pair of hooks, each of which has an L shape, and includes a latching portion that is engaged with the card slot and a parallel a light blocking column of the housing, the light guiding column comprises a plurality of light pipes arranged in a horizontal direction or a column shape, and a connecting body connecting the light guiding tubes in a longitudinal direction, wherein the outermost two light guiding tubes of the light guiding column are respectively disposed a pair of blocks having a spacing symmetry, a card slot for engaging the hook is formed between the pair of cards, and when the light guiding column is fixed, the light guiding tubes on both sides of the light guiding column are pressed oppositely, and the light guiding tube has a certain deflection The light guide tube can be bent and deformed slightly inward to be engaged in the pair of hooks, and the buckle portion is engaged in the corresponding card slot. The stopping portion is blocked from a side of the corresponding light guiding tube away from the housing, thereby fixing the light guiding column to the housing.

The light guide bar of the fixing device is pressed to deform to engage or disengage the hook of the casing, and the light guide column can be easily disassembled or installed.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a perspective exploded view of a preferred embodiment of a light guide column fixture of the present invention.

Fig. 2 is a perspective view showing the disassembly and assembly process of the preferred embodiment of the light guide column fixing device of the present invention.

Fig. 3 is a perspective view showing a fixed state of a preferred embodiment of the light guiding rod fixing device of the present invention.

Referring to FIG. 1, a preferred embodiment of the light guide fixing device of the present invention includes a light guide 10 and a housing 30 of an electronic device.

The light guide column 10 includes a plurality of strips or columns of laterally spaced light guide tubes 11 and a connecting body 12 that connects the light guide tubes 11 in a longitudinal direction. A pair of sliders 20 having a spacing symmetry are respectively disposed on the light guiding tubes 11 on both outer sides of the light guiding column 10. A pair of slots 21 are formed between the pair of blocks 20, and the outer side of each of the blocks 20 is inclined with respect to the horizontal direction of the light guide tube 11, and the inner side of each of the blocks 20 is vertical with respect to the horizontal direction of the light guide tube 11. surface.

The housing 30 is provided with a pair of opposite hooks 31. Each of the hooks 31 is formed inwardly from the housing 30. Each of the hooks 31 has an L shape and two symmetrical recesses are formed on the housing 30. Each of the hooks 31 includes a latching portion 32 that is perpendicular to the housing 30 and a stop portion 33 that is located at the end of the latching portion 32 and that is parallel to the housing 30.

Please refer to FIG. 2 and FIG. 3 simultaneously. When assembling, near the block 20 or the card slot 21, the light guide tubes 11 on both sides of the light guide column 10 are pressed toward each other. The light guide tube 11 has a certain deflection, so that the light guide tube can be made. 11 is slightly deformed inwardly to clamp the latching portion 32 of the hook 31 of the housing 30 into the slot 21 of the light guide tube 11. When the external force is removed, the light guide tube 11 is restored and deformed, and the hook 31 is blocked. The stopper 33 also blocks the outer wall surface 34 of the light guide tube 11.

When the hook 31 is engaged with the slot 21 of the light guide tube 11, the sliding of the light guide column 10 relative to the housing 30 can be restricted, which not only achieves a better fixing effect but also facilitates the disassembly and installation of the light guide column 10.

When disassembling, the light guide tubes 11 on both sides of the light guide column 10 are pressed toward each other to be bent and deformed slightly inward to disengage the light guide post 10 from the hook 31 of the housing 30.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. However, the above description is only the preferred embodiment of the present invention, and equivalent modifications or variations made by those skilled in the art to the present invention should be included in the following claims.
