Description

Technical Field

[0001] This utility model relates to the field of electronic device housings, specifically to an adjustable-size fiber optic demodulator housing. Background Technology

[0002] With the widespread application of fiber optic sensing technology in industrial monitoring, environmental sensing, and infrastructure security, the stability and environmental adaptability of fiber optic demodulators, as the core data processing unit of sensing systems, are becoming increasingly critical. Traditional solutions typically use fixed-size housings. Custom designs based on specific installation space or functional expansion requirements involve material cutting, mold development, and multiple assembly and debugging processes, resulting in long development cycles and high unit manufacturing costs, making them unsuitable for specialized fiber optic sensing applications. Existing demodulator housing designs struggle to meet the flexible deployment needs of diverse scenarios. Furthermore, when environmental parameters (such as cabinet space, heat dissipation conditions, or vibration levels) change, existing housings lack modular adjustment capabilities and cannot achieve dimensional adaptation through simple addition, subtraction, or recombination of standardized materials, forcing companies to repeatedly invest resources in mold development and verification.

[0040] The present invention will now be described in more detail with reference to the accompanying drawings. In the various drawings, the same elements are indicated by similar reference numerals. For clarity, the parts in the drawings are not drawn to scale.

[0041] Example 1

[0042] An adjustable-size fiber optic demodulator housing. Figure 1 A flowchart illustrating an embodiment of the present invention is shown. Figure 2 A schematic diagram of the fixing foot structure of one embodiment of the present invention is shown, as follows: Figure 1 and Figure 2 As shown, it includes:

[0043] Base plate 1, side plate 2 and fixing corner 3;

[0044] The side plate 2 includes multiple pieces, and two side plates 2 are connected by a fixed angle 3. The multiple side plates 2 form the side of the shell. The specific number of side plates 2 is not limited here. It can be three or more. In this embodiment, the number of side plates 2 is 4 pieces, and the number of fixed angles 3 is also 4. Every two side plates 2 are connected by one fixed angle 3.

[0045] The base plate 1 comprises two pieces, which respectively cover the upper and lower ends of the side surface formed by the multiple side plates 2 and the fixed angle 3; the size of the base plate 1 is greater than or equal to the area of ​​the two ends of the side surface formed by the multiple side plates 2 and the fixed angle 3.

[0046] The fixed angle 3 is a triangular prism structure, comprising a first edge 310, a second edge 320, and a third edge 330. The third edge 330 is arc-shaped. The first edge 310 has a first connecting portion 311, and the second edge 320 has a second connecting portion 321. The first edge 310 is connected to a side plate via the first connecting portion 311, and the second edge 320 is connected to another side plate via the second connecting portion 321. In this embodiment, the first connecting portion 311 and the second connecting portion 321 are flat grooves. The flat grooves are arranged along the axial direction of the fixed angle 3 and are adapted to the side plate 2. During installation, the side plate 1 is inserted into the flat groove, and the side plate is engaged by the two sides of the flat groove. Furthermore, in this embodiment, one side of the flat groove is connected to and smoothly transitions with the arc of the third edge 330. The arc can be oriented towards the outside of the shell.

[0047] The fixed angle 3 has first connecting holes 340 at both ends, which penetrate both ends of the fixed angle 3, enabling connection between the fixed angle 3 and the base plate 1, and also achieving the goal of lightweighting the fixed angle 3. The first connecting holes 340 are located at the center of the fixed angle 3. The base plate 1 has a first mounting hole 110, which connects to the end of the fixed angle 3 through the first mounting hole 110 and the first connecting hole 340. The position of the first mounting hole 110 is such that it matches the position of the first connecting hole 340 after the base plate 1 is closed. The fixed angle 3 also includes a fastener, which connects the base plate 1 to the end of the fixed angle 3 through the first mounting hole 110 and the first connecting hole 340. The fastener includes bolts, pins, or clips.

[0048] When bolts are used as fasteners, they pass through the first mounting hole 110 and the first connecting hole 340, and are then tightened with a nut. This provides high connection strength and stability, and can withstand significant external forces and vibrations, making it suitable for industrial environments where high housing stability is required. During installation, first align the base plate 1 with the fixing angle 3, ensuring the first mounting hole 110 and the first connecting hole 340 are coaxial. Then insert the bolt, and finally tighten the nut with a wrench. When pins are used as fasteners, the pins, through their interference fit or specific structure, can limit the relative displacement between the base plate 1 and the fixing angle 3 after being inserted into the two holes. This facilitates easy installation and disassembly, and is commonly used in scenarios requiring frequent disassembly and maintenance, such as fiber optic demodulator debugging in laboratory environments. Snap-on fasteners, on the other hand, achieve rapid connection through their elastic structure. This simple and efficient operation allows for quick assembly of the base plate and fixing angle, making it suitable for large-scale production scenarios where high installation efficiency is required.

[0049] Furthermore, in this embodiment, the side of the first edge 310 away from the third edge is provided with a first extension portion 312, and the side of the second edge 320 away from the third edge is provided with a second extension portion 322. When multiple side plates 2 are enclosed by the fixed angle 3, the first extension portion 312 abuts against one side plate 2, and the second extension portion 322 abuts against another side plate 2. The first extension portion 312 and the second extension portion 322 are extensions of the two sides, which can be partial or complete extensions. The first extension portion 312 and the second extension portion 322 added to the first edge 310 and the second edge 320 have the core function of enhancing the connection stability and sealing between the side plate 2 and the fixed angle 3. When multiple side panels 2 are enclosed or semi-enclosed by a fixed corner 3 to form a closed space, the first extension 312 abuts tightly against one side panel 2, and the second extension 322 abuts against another side panel 2. This abutting method not only effectively restricts the displacement of the side panels in the enclosing direction but also forms a double protective structure at the side panel joints, greatly reducing the generation of gaps and improving the dustproof and waterproof performance of the overall structure. The first extension 312 and the second extension 322 disperse the stress transmitted from the side panels to the fixed corner when under load. In traditional connection methods, the stress on the side panels is concentrated at the connection point between the edge and the fixed corner, which can easily cause excessive local stress and lead to structural damage. However, through the large-area abutment between the extension and the side panel, the stress can be evenly distributed to a larger contact surface between the fixed corner and the side panel, improving the load-bearing capacity and service life of the structure.

[0050] The first extension 312 and the second extension 322 are provided with second connecting holes 313 at both ends, and the base plate 1 is provided with a second mounting hole 120. The base plate 1 is connected to the end of the fixed angle 3 through the second mounting hole 120 and the second connecting hole 313. In the specific installation process, the cooperation of the second connecting hole 313 and the second mounting hole 120 provides a firm installation method for the connection between the base plate 1 and the end of the fixed angle 3. Bolts, rivets and other connectors can be used to achieve quick and reliable assembly. During installation, after passing the connector through the second mounting hole 120 and the second connecting hole 313 and tightening or riveting, the base plate 1 and the fixed angle 3 form a rigid connection, so that the entire structure has good stability in both the vertical and horizontal directions, effectively preventing problems such as loosening and deformation of the side plate and the base plate during use.

[0051] Furthermore, in this embodiment, the side plate 2 is provided with functional holes, including indicator light holes, fiber optic cable holes, and heat dissipation holes. The indicator light holes provide a window for visualizing the device's operating status. The fiber optic cable holes bridge the signal transmission gap. In scenarios such as communication equipment and data center cabinets, numerous fiber optic cables need to be connected inside the equipment for data transmission. The heat dissipation holes increase the airflow area, promoting heat exchange between the internal components of the equipment and the external environment. The heat dissipation holes can be louvered, honeycomb, or strip-shaped, etc.

[0052] Furthermore, in this embodiment, the base plate 1 is provided with a mating groove 130, which is adapted to the cross-section of the side plate 2 and the fixed angle 3.

[0053] Furthermore, in this embodiment, Figure 3 An exploded view of the overall structure of another embodiment of the present invention is shown; Figure 4 A schematic diagram of the overall structure of another embodiment of the present invention is shown; as follows: Figure 3 and Figure 4 As shown, the side plate 2 and the fixed corner 3 are connected by a snap-fit ​​part 210. The snap-fit ​​part 210 can be an extension block perpendicular to the side plate surface along the edge of the side plate. The extension block can be located on a part of the plate surface or the entire edge of the side plate. The first extension part 312 is provided with a snap-fit ​​groove 3121. The snap-fit ​​part 210 and the snap-fit ​​groove 3121 are adapted to each other. The side plate 2 is connected to the fixed corner 3 through the snap-fit ​​part 210 and the snap-fit ​​groove 3121. The cooperation between the snap-fit ​​part 210 and the snap-fit ​​groove 3121 forms an interlocking mechanism. When multiple side plates are enclosed by the fixed corner, the snap-fit ​​structure works together at each connection point to evenly distribute the force on the side plates to the fixed corner, effectively avoiding stress concentration. In the vertical and horizontal directions, the side plates and the fixed corner are tightly connected by the snap-fit ​​structure. The multi-dimensional fixing method enables the overall structure to maintain good stability and reliability when subjected to complex working conditions such as external impact and vibration.

[0054] This utility model achieves flexible size adjustment by splicing the base plate, side plates and fixed corners. It reduces the types of spare parts through standardized modules, thereby reducing production and inventory costs. The size can be freely combined according to actual needs, eliminating the need for custom-made overall shells, shortening the delivery cycle. In case of partial damage, only a single side plate or fixed corner needs to be replaced, without scrapping the entire shell.

[0055] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.

[0056] The above description does not provide detailed explanations of the technical aspects of each layer's patterning and etching. However, those skilled in the art should understand that various methods existing in the prior art can be used to form layers and regions of the desired shape. Furthermore, to form the same structure, those skilled in the art can also design methods that are not entirely identical to those described above.
