Description

Technical Field

[0001] This utility model relates to the field of optical module duct cover technology, specifically a crack-resistant OSFP optical module duct cover. Background Technology

[0002] As a core component of fiber optic communication systems, the reliability of the optical module's packaging structure directly affects signal transmission quality. Traditional OSFP optical module duct covers are mostly made of metal, which, while possessing a certain strength, suffers from problems such as heavy weight, high cost, and limited electromagnetic shielding performance. While plastic duct covers offer significant advantages in terms of lightweight, they are prone to failure due to the following factors: First, the sharp corners of the joints, under thermal expansion and contraction cycles or external forces, result in a stress concentration factor as high as 3, easily leading to cracking; second, the thin-walled structure is prone to deformation under insertion / extraction forces or vibration environments, causing internal components to shift or be damaged; third, traditional snap-fit ​​connections are prone to loosening due to improper assembly or long-term use, reducing sealing performance; fourth, defects such as insufficient glue and shrinkage during the injection molding process lead to insufficient dimensional accuracy, affecting the fit accuracy with other components.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1-3 As shown, this utility model provides a crack-resistant OSFP optical module duct cover, including a duct cover body 1. The duct cover body 1 has at least one joint 2. The joint 2 is provided with a crack-resistant reinforcing structure 3 and an arc transition structure 4. The inner wall of the duct cover body 1 is provided with a deformation-resistant support structure 5. The duct cover body 1 is provided with a locking structure 6, which is used to cooperate with external assembly components.

[0022] The arc transition section 8 (radius 0.5-1.5mm) of the joint 2 eliminates sharp corners, distributing concentrated stress evenly along the arc surface. According to elasticity theory, the stress concentration factor α is directly related to the geometry; sharp corners significantly increase the α value (e.g., α = 3 at the edge of a circular hole), while the arc transition reduces α to below 1.5. The triangular reinforcing rib 12 (integral molding) extending along the joint 2 utilizes the mechanical stability of a triangle, increasing the moment of inertia of the section to enhance bending resistance. The rigidity of the triangular reinforcing rib 12 is significantly higher than that of a rectangular structure, and the integral molding process reduces weak points.

[0023] Furthermore, the arc transition structure 4 includes an arc transition section 8 disposed at the joint 2, the radius of which is 0.5mm-1.5mm. The arc transition reduces stress concentration, significantly reducing the risk of cracking of the pipe cover under thermal expansion and contraction cycles.

[0024] Furthermore, the crack-resistant reinforcing structure 3 includes a reinforcing rib 12 extending along the length of the joint 2. The reinforcing rib 12 has a triangular cross-section, and it is integrally formed with the pipe cover body 1. The reinforcing rib 12 design significantly improves overall rigidity with a small increase in material, meeting the lightweight requirements of OSFP optical modules. The integral forming process can be directly achieved through injection molding, eliminating the need for secondary processing and reducing production costs.

[0025] Furthermore, the anti-deformation support structure 5 includes several support ribs 9, which are distributed at intervals along the length of the pipe cover body 1. The spacing between adjacent support ribs 9 is 5mm-8mm, and the height of the support ribs 9 is 1 / 3-1 / 2 of the distance from the inner wall to the outer wall of the pipe cover body 1.

[0026] Support ribs 9, spaced 5-8mm apart on the inner wall, are 1 / 3 to 1 / 2 the height of the wall thickness, forming a support system similar to an "I" beam. According to Euler's buckling theory, a reasonable spacing can prevent elastic buckling of the support ribs 9, ensuring no deformation under external pressure (such as insertion / extraction forces ≤50N during assembly).

[0027] Furthermore, the engaging structure 6 includes at least two mounting bosses 10, each mounting boss 10 having a stepped guide surface 7, and each mounting boss 10 having a latch 11 at its end. The stepped guide surface 7 (angle 15°-30°) of the mounting boss 10 provides an automatic alignment function during assembly, reducing insertion resistance and preventing structural damage caused by oblique insertion. The end latch 11 adopts an elastic structure, utilizing the elastic deformation of the material to achieve irreversible locking.

[0028] Furthermore, the outer wall of the pipe cover body 1 is provided with a visual inspection auxiliary structure, which includes a color difference marking strip extending along the length direction of the pipe cover body 1. The color of the color difference marking strip has a preset color difference from the main color of the pipe cover body 1.

[0029] Color-coded markings on the outer wall (such as a black base with red stripes) enable rapid positioning within 0.1 seconds in industrial vision systems through color contrast. Continuity detection of the markings can identify improper installation, reducing the rate of missed detections.

[0030] Furthermore, the wall thickness of the pipe cover body 1 is set to 1.2mm-1.5mm in areas prone to insufficient glue, and 0.8mm-1.0mm in non-short-glue areas. These short-glue-prone areas are those identified as having a high risk of insufficient glue by mold flow analysis. By simulating melt flow, areas prone to insufficient glue (such as the base of reinforcing rib 12 and the connection point of snap-fit ​​11) are identified, and the wall thickness is increased to 1.2-1.5mm to ensure no short-shot defects when the filling pressure is ≥80MPa. The wall thickness in non-short-glue-prone areas is 0.8-1.0mm. This reduces material usage and shortens the injection molding cycle while still meeting strength requirements. Wall thickness optimization reduces shrinkage of the injection molded parts, improves dimensional accuracy, and simultaneously saves material and increases molding efficiency.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
