[0003] However, in the process of filling glue on the circuit board, when there are multiple patch electronic indicator lights side by side in a row, since the glue usually filled is transparent, when one of the indicator lights is on, the light it emits will be The transparent glue refracts to the position of the adjacent indicator light, resulting in the adjacent indicator light not being lit, but the indicator mark on the shell is also easily considered by the user to be on due to "light leakage", resulting in operational problems. misunderstanding

Embodiment Construction
[0018] The specific implementation of an electronic indicator light guide cover provided by the present invention will be described in detail below in conjunction with the accompanying drawings.
[0019] Please refer to figure 1 , is a schematic front view 11 , a schematic side view 12 , a top view 13 , and a bottom view 14 of an electronic indicator light guide cover according to a specific embodiment of the present invention. Simultaneously combine figure 2 , to describe the specific implementation manner.
[0020] The electronic indicator light guide cover is integrally formed, and has: 1) a circular light guide tube 110, the top of which is a light outlet, and the light outlet points to the corresponding indicator mark 201 on the housing; 2) a circular light guide tube 110. A concentric circular indicator light cover 111 is connected below the light guide tube 110 , and the inner cavity diameter of the circular indicator light cover 111 is larger than the inner cavity d...

Abstract
An electronic indicator light guide cover. The light guide cover is integrally formed, and specifically includes: 1) a light guide tube, above which is a light outlet, pointing to the corresponding indicator mark on the housing. 2) A circular indicator light cover with opposite openings is connected under the light guide tube. The diameter of the circular indicator light cover is larger than that of the light guide tube, and larger than the diameter or width of the SMD electronic indicator light. The opposite opening on the wall of the circular indicator light cover is used to allow glue to flow into and cover the electronic indicator light; 3) Two circular light guide cover feet are arranged on the outer side of the circular indicator light cover. The two light guide cover feet are perpendicular to the direction of the opening on the wall of the circular indicator light cover. The leg of the light guide cover has an outward L-shaped protrusion, which is used to embed into the fixing bayonet on the circuit board to play a fixing role. 4) The light guide cover is made of non-transparent engineering plastics. The light guide cover of the electronic indicator light can solve the problem of light leakage of the electronic indicator light, especially the light leakage problem of the patch electronic indicator light in the glue filling process of the circuit board.
Description
technical field [0001] The invention relates to the field of electronic product manufacturing, in particular to an electronic indicator light guide cover. Background technique [0002] Many existing electronic devices turn on indicator lights when they are in operation to display information such as operating status and working mode for users' reference. For electronic devices that are prone to moisture in the use environment, such as smart bathroom controllers, glue potting is usually used, that is, a layer of glue is covered around the circuit board and on-board components to make the circuit board waterproof and moisture-proof. [0003] However, in the process of circuit board glue filling, when there are multiple patch electronic indicator lights side by side in a row, since the glue usually filled is transparent, when one of the indicator lights is on, the light it emits will be The transparent glue is refracted to the position of the adjacent indicator light, so that ...
