Description

Technical Field

[0001] This utility model relates to light guide post assembly technology, and in particular to an integrated assembly structure of multiple light guide posts applied to junction boxes. Background Technology

[0002] In industrial automation control systems, junction boxes, as the core components for signal distribution from sensors and other devices, are typically equipped with multiple signal channels. Each channel needs to be equipped with a corresponding indicator light to provide feedback on the working status. Light guides, as the light transmission components for the indicator lights, need to be installed one-to-one with the indicator lights to ensure clear light display.

[0003] To simplify the assembly process of junction boxes and reduce the number of parts, existing technologies are increasingly adopting a design approach of "integrating two or more light guide pillars into one unit," which combines multiple light guide pillars into a single assembly unit. However, this design faces the following key technical challenges in practical applications:

[0004] Processing deviations lead to mismatched spacing: There are processing tolerances in both the light guide post itself and the mounting holes of the light guide post on the junction box shell. If the spacing of the fixed structure of the integrated light guide post cannot be adjusted, it will cause a mismatch between the spacing of the light guide post and the mounting hole, which will lead to installation difficulties - either the light guide post cannot be installed smoothly into the mounting hole, or it will become loose after installation.

[0005] Tilting during installation can cause a chain of problems: Mismatched spacing can cause the light guide to tilt during installation. On the one hand, this can cause misalignment between the light guide and the indicator lights on the PCBA board (printed circuit board assembly), resulting in "light polarization" and affecting the status display effect. On the other hand, the tilted light guide can damage the sealing structure inside the junction box, causing potting compound to overflow during subsequent potting operations. This not only affects the product's appearance but may also damage the internal circuitry.

[0006] Cost and efficiency issues: If the integrated design is abandoned and a single light guide column is installed separately, the amount of materials will increase, the processing, procurement and inventory management costs will increase, the assembly time will be extended, and the production efficiency will be reduced.

[0007] In view of the shortcomings of the existing technology, there is an urgent need to design an integrated assembly structure that can compensate for spacing deviations and ensure the precise installation of light guides, so as to solve problems such as installation difficulties, light polarization and potting overflow, while taking into account both assembly efficiency and product quality. Utility Model Content

[0008] The purpose of this utility model is to provide an integrated assembly structure for multiple light guide columns applied to junction boxes. By optimizing the structural design, it solves the installation problems caused by processing deviations in existing integrated light guide columns, while reducing costs and improving assembly quality.

[0009] To achieve the above and other related objectives, the technical solution provided by this utility model is: an integrated assembly structure of multiple light guide pillars applied to a junction box, comprising:

[0010] The light guide section includes n sets of light guide pillars;

[0011] The connecting part includes n-1 sets of elastic arms, which are used to elastically connect two adjacent sets of light guide posts to compensate for the installation spacing deviation of the light guide posts;

[0012] Where n≥2.

[0013] The preferred technical solution is that all n groups of light guide columns are vertically arranged.

[0014] The preferred technical solution is that the elastic arm is configured as a horizontally arranged S-shaped structure, and the elastic arm is configured to compress or extend the spacing between two adjacent sets of light guide columns.

[0015] A preferred technical solution is that the light guide post further includes an annular boss formed on its outer periphery, which is used to cooperate with the pressing mechanism to achieve pressing.

[0016] The preferred technical solution is that the light guide and the connecting part are integrally injection molded from plastic.

[0017] Due to the application of the above technical solution, the beneficial effects of this utility model are as follows:

[0018] Solving the spacing deviation problem: The S-shaped elastic arm can adjust the spacing through elastic deformation, effectively compensating for the machining tolerance of the light guide post and the housing mounting hole, avoiding installation difficulties caused by spacing mismatch, and improving the smoothness of the light guide post installation operation;

[0019] Reduce costs and improve efficiency: The integrated design of the n-group light guide columns reduces the material quantity of a single light guide column, thereby reducing processing, procurement, and inventory management costs; the integrated assembly also simplifies the installation process, shortens assembly time, and improves production efficiency.

[0020] Stable and durable structure: The one-piece injection molding process and high-quality plastic materials ensure high overall structural strength, and the elastic arm can recover after deformation. It is not easily damaged during long-term use and extends the product's service life. Attached Figure Description
