Description

Technical Field

[0001] This utility model belongs to the field of communication equipment, and in particular relates to a communication module. Background Technology

[0002] In the field of communication equipment technology, the operating status of communication modules typically requires visual feedback via indicator lights. To achieve this, traditional designs usually integrate indicator lights onto the PCB board inside the module, and use light guides to direct the light emitted by the indicator lights to the outside of the module's top cover for user observation.

[0003] However, existing light guide structures have the following drawbacks: the light guide column and the module cover are separate designs, meaning the light guide column, as an independent component, needs to be installed separately between the cover and the PCB board. In actual assembly, the cover and light guide column need to be fixed separately, and it is essential to ensure that the light-input end of the light guide column is precisely aligned with the PCB indicator light and that the light-output end matches the observation window of the cover. This process is cumbersome and inefficient. Furthermore, the separate structure is prone to reduced light guiding effect (such as light leakage or light diffusion) due to assembly deviations, or structural reliability may be affected by component loosening during long-term use, thus reducing the user experience and lifespan of the product. Utility Model Content

[0004] The technical objective of this invention is to provide a communication module to solve the light guiding problem of existing communication modules.

[0005] To solve the above problems, the technical solution of this utility model is as follows: A communication module, comprising: The housing has a receiving cavity inside; A PCB board is placed inside the cavity, and an indicator light is installed above the PCB board; The housing has an opening that connects the receiving cavity to the outside. A transparent cover is installed at the opening, and the periphery of the cover is interference-fitted with the inner wall of the housing. The cover plate has an integrally formed light guide column. When the cover plate is in the opening, the indicator light source is located below the corresponding light guide column and is configured to allow the light emitted by the indicator light source to pass through the light guide column and out of the housing to indicate the working status of the communication module in real time.

[0006] The light guide column is a hollow column, configured to improve the transmittance of the indicator light source.

[0007] The light guide column is made of transparent material.

[0008] The light guide hole is formed by the recess at the connection between the light guide post and the cover plate.

[0009] More preferably, the upper surface of the cover plate where the light guide hole is not obstructed is also divided into an identification area, which is configured to be used for attaching labels.

[0010] More preferably, a raised portion is provided around the upper surface of the cover plate, which is configured to facilitate the pasting of labels.

[0011] The protrusion and the inner wall of the housing form a recessed sealing groove, which is configured to inject sealant to achieve circumferential sealing.

[0012] Because of the adoption of the above technical solution, this utility model has the following advantages and positive effects compared with the prior art: This invention integrates the cover plate and light guide post into a single unit, eliminating the need for assembly and making installation more convenient. Furthermore, because the cover plate and light guide post are integrally formed, there are no gaps between them, eliminating the risk of water leakage. Both the cover plate and light guide post are made of transparent material, ensuring that the light from the indicator light source can pass through the housing.

[0013] The light guide column has a hollow interior, which increases the light transmittance.

[0014] The upper surface of the cover plate is also divided into an identification area around the light guide column for attaching labels; after the label is attached to the identification area, only the light guide column is exposed, so as to display product information through the label while avoiding the light emitted by the indicator light source from shining through the entire transparent plate.

[0015] The upper surface of the cover plate has a raised ring around the marking area to facilitate the positioning of the label when it is pasted; and the light guide post is recessed at the connection of the cover plate to form a light guide hole that can more accurately position the label when it is pasted.

[0016] A sealing groove is formed between the protrusion and the inner wall of the housing. By injecting sealant into the sealing groove, a circumferential seal is achieved to prevent water from entering the sealing cavity. In addition, the sealant, together with the label, covers the entire upper surface of the cover, leaving only the light guide column exposed to prevent the light emitted by the indicator light source from shining through other parts of the cover.

Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0021] To keep the drawings concise, only the parts relevant to this invention are shown schematically in each figure, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some figures, only one of the components with the same structure or function is schematically depicted, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0022] The communication module proposed in this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of this utility model will become clearer from the following description and claims.

[0023] Example See Figure 1 and Figure 2 This embodiment provides a communication module, which has an outer shell 1 and an inner cavity 2. A PCB board 3 is placed inside the cavity 2, and an indicator light source 4 is mounted above the PCB board 3. The shell 1 has an opening connecting the cavity 2 to the outside, and a transparent cover plate 5 is installed at the opening. The periphery of the cover plate 5 is interference-fitted with the inner wall of the shell 1. A light guide post 6 is integrally formed on the cover plate 5. When the cover plate 5 is located at the opening, the indicator light source 4 is located below the corresponding light guide post 6, thereby allowing the light emitted by the indicator light source 4 to pass through the light guide post 6 and exit the shell 1 to indicate the real-time working status of the communication module. Since the cover plate 5 and the light guide post 6 are integrally formed, there is no need to assemble the cover plate 5 and the light guide post 6 separately during assembly, making overall assembly more convenient. Furthermore, because the cover plate 5 and the light guide post 6 are integrally formed, there is no gap between the cover plate 5 and the light guide post 6, avoiding the risk of water leakage.

[0024] Furthermore, in this embodiment, both the light guide column 6 and the cover plate 5 are made of transparent material, so they will not affect the light from the indicator light source 4 passing through the housing 1. In addition, the light guide column 6 is a hollow column with a hollow interior, which further improves the light transmittance of the indicator light source 4.

[0025] Furthermore, in this embodiment, an identification area 7 is also defined on the upper surface of the cover plate 5 where the light guide hole 9 is not obstructed, for attaching labels. After the label is attached to the identification area 7, only the light guide column 6 is exposed, so that product information is displayed through the label while preventing the light emitted by the indicator light source 4 from shining through the entire transparent cover plate 5.

[0026] To facilitate label application, a raised portion 8 is provided around the upper surface of the cover plate 5, which facilitates label positioning during application. Furthermore, a recessed light guide hole 9 is formed at the connection between the light guide post 6 and the cover plate 5, providing even more accurate label placement. A recessed sealing groove 10 is formed between the raised portion 8 and the inner wall of the housing 1. Sealant is applied into the sealing groove 10 to achieve a circumferential seal, preventing water from entering the receiving cavity 2. The sealant, along with the label, completely covers the upper surface of the cover plate 5, exposing only the light guide post 6, preventing light emitted from the indicator light source 4 from leaking out from other parts of the cover plate 5.

[0027] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they shall still fall within the protection scope of the present invention.
