Description

Technical Field

[0001] This disclosure relates to the field of mechanical connection technology, specifically to a joint with a reinforcing rib structure, suitable for scenarios such as pipe connections requiring high axial strength, lightweight design and resistance to deformation. Background Technology

[0002] In modern industrial systems, pipeline systems for transporting fluids such as liquids and gases are widely used in numerous fields, including energy, chemical engineering, metallurgy, and construction, serving as crucial infrastructure to ensure the normal operation of production activities. The efficient operation of these pipeline systems directly impacts the efficiency and safety of industrial production. As the core component connecting pipelines, the performance of joints directly affects the reliability, safety, and service life of the entire pipeline system, playing a vital role in the stable operation of industrial production.

[0003] The quality of a joint is closely related to its manufacturing process. Defects in the manufacturing process often lead to poor joint quality, which not only affects the sealing performance and strength of the joint but may also cause other hidden dangers during long-term use. Poor-quality joints are prone to deformation during or after assembly. Joint deformation directly reduces the joint's strength, thereby affecting the pressure-bearing capacity and safety of the entire pipeline system.

[0004] Joint strength is a critical factor in ensuring the normal operation of a pipeline system, directly determining its ability to withstand internal fluid pressure and various loads imposed by the external environment. Taking long-distance oil and gas pipelines as an example, the internal fluid pressure can typically reach tens or even hundreds of megapascals. Under such high pressure, if a joint deforms and its strength decreases due to quality issues, cracks and fractures are highly likely to occur, leading to serious safety accidents and significant economic losses. Furthermore, joint strength also affects the stability of the pipeline system under extreme weather conditions, such as earthquakes and storms, where joint quality is particularly important.

[0005] The quality of joints directly affects the reliability and safety of piping systems. Besides causing joint deformation, reduced strength, and ultimately pipe rupture, substandard joints can also lead to fluid leaks due to poor sealing performance. Fluid leaks not only waste resources but can also pollute the environment and even cause irreversible damage to the surrounding ecosystem. Furthermore, joint quality affects the service life of the piping system; high-quality joints can significantly extend the system's lifespan, reduce maintenance costs and downtime, and ensure the continuity and efficiency of industrial production.

[0006] In summary, there are still some issues that need improvement in pipe fittings for fluid transmission in modern industry. With the continuous development of industrial technology, the performance requirements for pipeline systems are increasing, thus urgently requiring the development of a new type of fitting to solve the problems of existing fittings and meet the needs of industrial production. Summary of the Invention

[0007] One objective of this disclosure is to overcome the shortcomings of related technologies and to provide a connector that addresses the deficiencies of existing connectors in terms of strength, manufacturing process, and performance stability. For example, traditional connectors use a solid structure to ensure strength, resulting in high material consumption and cost, and internal pores can easily occur during injection molding, affecting the density of the structure.

[0008] This disclosure provides a connector including a body and a protrusion, the protrusion being shaped into a column, wherein the connector further includes a plurality of reinforcing ribs disposed on the protrusion near the outer periphery of the body, the outer surfaces of all the reinforcing ribs collectively defining a side surface of a body that matches the column.

[0009] In a possible implementation, the reinforcing rib includes a first rib, the plane of which is at an angle to the bottom surface of the protrusion, and the first rib is adjacent to the outer side surface of the protrusion.

[0010] In a possible implementation, the plane containing the first rib is perpendicular to the bottom surface of the protrusion.

[0011] In a possible implementation, the first ribs are evenly spaced apart from each other along the circumference of the protrusion.

[0012] In a possible implementation, the first ribs are non-uniformly spaced apart from each other along the circumference of the protrusion.

[0013] In a possible implementation, each of the first ribs has the same thickness.

[0014] In a possible implementation, the plane containing each of the first ribs passes through the axis of the protrusion.

[0015] In a possible implementation, the plane containing all the first ribs does not pass through the axis of the protrusion.

[0016] In a possible implementation, the first ribs are parallel to each other.

[0017] In a possible implementation, at least some of the first ribs are not parallel to each other.

[0018] In a possible implementation, the plane containing a portion of the first rib passes through the axis of the protrusion, while the plane containing the remaining first ribs does not pass through the axis of the protrusion.

[0019] In a possible implementation, the reinforcing rib includes a second rib that intersects with the first rib.

[0020] In a possible implementation, the plane containing the second rib is perpendicular to the bottom surface of the protrusion.

[0021] In a possible implementation, at least a portion of the thickness of the first rib narrows as it approaches the protrusion.

[0022] In a possible implementation, at least a portion of the thickness of the first rib increases as it approaches the protrusion.

[0023] In a possible implementation, the column is a cylinder and the frustum is a frustum.

[0024] In a possible implementation, the prism is a prism and the frustum is a frustum.

[0025] The joint design disclosed herein effectively reduces material usage while ensuring equivalent joint strength, achieving lightweighting and cost savings. During injection molding, it promotes more uniform cooling, reduces internal porosity, and improves structural density. Furthermore, the support system formed by reinforcing ribs enhances the axial compressive strength of the joint, simplifies mold design, optimizes manufacturing processes, and reduces production costs.

Detailed Implementation

[0056] The following descriptions of exemplary embodiments refer to the accompanying drawings. These exemplary embodiments are merely specific implementations of this disclosure and are not intended to limit the scope of this disclosure in any way. Directional terms used in this disclosure, such as [up], [down], [front], [back], [left], [right], [inner], [outer], [end], etc., refer only to directions referenced to the accompanying drawings. Therefore, the directional terms used are for illustration and understanding of this disclosure and not for limiting it. In the drawings, structurally similar units are denoted by the same reference numerals. In the drawings, for clarity and ease of description, the dimensions of some components have been exaggerated and / or the structures of some components simplified. That is, the dimensions and structures of each component shown in the drawings are schematic and are not intended to limit the scope of this disclosure.

[0057] In modern industrial applications, joints are key components for connecting pipelines, and their performance directly affects the reliability, safety, and service life of the pipeline system.

[0058] As a prelude to embodiments of this disclosure, a connector employing a one-piece column-tablet structure is provided. In some embodiments, the connector can be manufactured by injection molding or other manufacturing processes.

[0059] Figure 13 The figure shows a schematic perspective view of a joint design employing an integrated column-tablet structure according to exemplary embodiments disclosed herein. Figure 13 As shown, the connector 10 includes a main body 1 and a protrusion 2. In this example, the protrusion 2 is formed as a cylinder. In the connector 10, a frustum of a cone (hereinafter referred to as a truncated cone) 4, integrally formed with the protrusion 2, is provided adjacent to the main body 1. The top surface of the truncated cone 4 coincides with the bottom surface of the cylinder (i.e., the protrusion 2). In other words, the axis of the cylinder and the axis of the truncated cone are collinear.

[0060] After testing the joint design using the integrated column-frustum structure described above, the inventors of this disclosure discovered that this design has problems including, but not limited to, the following:

[0061] 1. Weight and material waste: The integrated column-platform structure requires a lot of material, resulting in bulky joints and increased transportation and installation costs. This is especially true in weight-sensitive fields such as aerospace and automotive manufacturing, where it is difficult to meet lightweight requirements.

[0062] 2. Manufacturing Defects: During injection molding, thick-walled structures are prone to internal defects such as porosity and shrinkage marks. These defects can significantly reduce the mechanical properties of the joint, such as compressive strength and fatigue resistance. Furthermore, internal defects can also cause localized stress concentration during the mating process, increasing the risk of fracture.

[0063] 3. Poor adaptability: Traditional joint structures typically employ a uniform thickness design, making it impossible to adjust local strength according to the load direction. For example, when subjected to lateral forces, the uniform thickness design of the platform cannot effectively disperse stress, leading to joints prone to plastic deformation or fatigue failure.

[0064] Therefore, there is an urgent need for a new type of joint structure that can achieve lightweight design while ensuring strength and improving manufacturability, so as to meet the needs of modern industry for high-performance joints.

[0065] The embodiments of this disclosure provide several lightweight, high-strength joint structures that, by optimizing the layout of reinforcing ribs and geometric features, reduce material usage while improving axial compressive strength and manufacturability.

[0066] Embodiments of this disclosure provide several types of connectors 10. (See reference...) Figures 1A to 11B In any case, the connector 10 may include a body 1 and a protrusion 2. Depending on the application of the connector 10, the body 1 may adopt any suitable structure. Therefore, the body 1 is simplified in the illustration of the connector 10. The portion below the break line is indicated by reference numeral 1 as the body 1 of the connector 10, which will be readily understood by those skilled in the art.

[0067] As shown in the figure, the protrusion 2 can be formed into a column. In some embodiments, the connector 10 may further include a plurality of reinforcing ribs 3. In some embodiments, the reinforcing ribs 3 may be disposed near the outer periphery of the body 1 of the protrusion 2. In some embodiments, the outer surfaces of the reinforcing ribs 3 may collectively define a side surface of a body that matches the column.

[0068] As used herein, the term "outer surface of the stiffener" 3os (e.g., as...) Figure 1A (As shown) refers to the surface of the reinforcing rib facing away from the axis of the protrusion. This surface has a certain geometric shape in space. The outer surfaces 3os of multiple reinforcing ribs cooperate with each other and present a shape similar to the side of a specific platform as a whole.

[0069] Specifically, each reinforcing rib has its own outer surface. When these reinforcing ribs are arranged in a specific way near the outer periphery of the protrusion, the shape formed by the combination of these outer surfaces resembles the side surface of a frustum. For example, as shown in Figure 1, multiple reinforcing ribs are distributed at equal intervals along the outer periphery of the cylindrical protrusion. The combination of their outer surfaces may present a shape similar to the side surface of a frustum, that is, from one end of the protrusion near the main body to the other end, the overall outline gradually tapers, just like the changing trend of the side surface of a frustum from the large base to the small base.

[0070] More intuitively, the outer surfaces 3os of the reinforcing ribs can be considered as small planes. When a continuous curved surface is used to fit as closely as possible to these small planes, the resulting surface is their envelope. In the joint design of this example, the shape of this envelope precisely matches the side shape of a platform. That is to say, from an overall perspective, the envelope of the outer surfaces of these reinforcing ribs forms an outline similar to the side of a platform, just as wrapping a piece of paper around the outer surfaces 3os of multiple reinforcing ribs ultimately presents the shape of the side of a platform.

[0071] The term "prism" refers to a solid figure formed by translating a two-dimensional shape (such as a circle or polygon) a certain distance along a direction perpendicular to the base. Prisms include, but are not limited to, cylinders (with a circle as their base) and right prisms (with a polygon as their base, and their lateral edges perpendicular to the base). A prism has two parallel and congruent bases, and lateral surfaces connecting the two bases, which are either parallelograms (for right prisms) or curved surfaces (for cylinders).

[0072] A frustum is the portion of a cone truncated by a plane parallel to its base, between the cross-section and the base. It has an upper base, a lower base, and a lateral surface. The term "frustum 'matching' a prism" refers to a frustum whose smaller (upper) base (or top) is congruent to the base of the prism, and whose axis coincides with (is collinear with) the axis of the prism. When the prism is a cylinder, the matching frustum is a frustum of a cone (truncated cone). When the prism is a right prism, the matching frustum is a right frustum. Specifically, if the right prism is a regular N-prism, the matching frustum is a regular N-frustum; if the prism is an irregular right prism, the matching frustum is an irregular right frustum whose smaller (upper) base (or top) is congruent to the base of the irregular right prism.

[0073] In industrial production, material costs, product weight, quality, and manufacturing processes are all key factors affecting the economics and practicality of a product. The joint solution presented in this example demonstrates significant advantages in these aspects. Traditional designs often use solid platforms to ensure structural strength, but this consumes a large amount of material, results in significant weight, and incurs high transportation and installation costs. The novel joint design disclosed here replaces the traditional solid platform with reinforcing ribs, significantly reducing material usage while maintaining equivalent strength to the traditional solid platform. This achieves a lightweight design for the joint 10, reducing transportation and installation difficulties and costs, and also lowering raw material procurement costs. It has broad application prospects in fields with strict weight requirements, such as aerospace and automotive manufacturing.

[0074] It is understandable that during injection molding, traditional structures are prone to internal porosity due to uneven heat dissipation, reducing the density and performance of the product. The ribbed structure of this connector design allows for more even heat dissipation during injection molding, preventing localized overheating or undercooling, ensuring uniform cooling, significantly reducing internal porosity, improving structural density, enhancing the strength and reliability of the connector 10, enabling it to better adapt to complex operating environments, and extending its service life.

[0075] It is understandable that in actual use, joint 10 needs to withstand axial loads and has high requirements for resistance to deformation. The reinforcing ribs in this joint design can evenly distribute the load, avoid local stress concentration, and significantly improve the compressive strength of joint 10. Compared with traditional structures, it can better maintain shape and structural integrity, reduce the risk of deformation and damage, and provide reliable protection for the stable operation of the pipeline system.

[0076] In addition, the mold injection cycle also affects product production costs and efficiency. For example Figure 13 The injection molding cycle of the joint design using an integrated column-tablet structure shown is long, while the reference design... Figures 1A to 11B The ribbed structure of this connector design, as shown, shortens the mold injection cycle, enabling the production of more connector components per unit time and improving production efficiency.

[0077] Now for reference Figure 1A and Figure 1B . Figure 1A The figure shows a schematic front view of one embodiment of the connector 10 according to the exemplary embodiments disclosed herein. Figure 1B The figure shows a schematic top view of one embodiment of the connector 10 according to the exemplary embodiments disclosed herein.

[0078] In some embodiments, the reinforcing rib may include a first rib. As used herein, the term "first rib" refers to a strip-shaped component, such as a rib, used to enhance the structural strength of the joint, which may be flat or plate-shaped, etc.

[0079] In some embodiments, the plane containing the first rib 31 may be perpendicular to the bottom surface of the protrusion 2. As used herein, the term "plane containing the first rib" 31s may refer to a plane on the first rib 31, excluding the outer surface 31os of the first rib 31, defined by a face that forms a right dihedral or acute dihedral angle with the bottom surface of the protrusion 2. This plane is of great significance in the structure of the joint 10, as it embodies the specific spatial positional relationship and angular setting between the first rib 31 and the protrusion 2. When the plane containing the first rib 31s forms a right dihedral angle with the bottom surface of the protrusion 2, the first rib 31 can be set perpendicular to the bottom surface of the protrusion 2. When the joint 10 is subjected to axial load, the first rib 31 can more directly and effectively transmit the axial force to the protrusion 2, enhancing the load-bearing capacity and stability of the joint 10 in the axial direction, which is suitable for applications requiring the resistance to large axial pressure. Specifically, when the plane containing the first rib 31s is perpendicular to the bottom surface of the protrusion 2, the first rib can most directly transmit the axial force borne by the joint 10 to the protrusion 2. In some applications that require withstanding large axial pressure, such as pipe connections in large mechanical equipment, the first rib 31, which is set vertically relative to the bottom surface of the protrusion 2, can effectively prevent the protrusion from bending or deforming under axial pressure, ensuring that the joint can work stably and greatly improving the joint's performance in axial load-bearing capacity.

[0080] Now for reference Figure 2A and Figure 2B . Figure 2A The figure shows a schematic front view of one embodiment of the connector according to the exemplary embodiments disclosed herein. Figure 2B The figure shows a schematic top view of one embodiment of the connector according to the exemplary embodiments disclosed herein.

[0081] In some embodiments, the plane 31s containing the first rib can be at an angle to the bottom surface of the protrusion. This angle allows the first rib to support the joint 10 in a way that is inclined relative to the bottom surface of the protrusion 2, better dispersing the external forces borne by the joint 10 and enhancing the joint 10's resistance to deformation. For example, in some pipe connection scenarios subjected to complex stresses, the angle between the first rib and the bottom surface can decompose and transmit forces in different directions, reducing local stress concentration.

[0082] In the context of this disclosure, the angle between the plane 31s containing the first rib and the bottom surface of the protrusion 2 generally refers to an acute dihedral angle. In particular, for a single first rib 31 arranged in the "inclined" manner described above, it generally has two such acute dihedral angles. By way of example and not limitation, for a single first rib 31, the smaller of its two acute dihedral angles can be taken as the angle between the plane 31s containing the first rib and the bottom surface of the protrusion 2.

[0083] When the plane 31s where the first rib is located forms an acute dihedral angle with the bottom surface of the protrusion 2, the first rib 31 is arranged in an inclined posture relative to the bottom surface of the protrusion 2. This arrangement can change the force transmission path and distribution pattern, so that when the joint is subjected to external force, the force can be distributed more evenly to various parts of the joint, avoiding local stress concentration, thereby improving the overall deformation resistance and reliability of the joint. For example, it is suitable for working environments where the joint is subjected to complex stress.

[0084] In some embodiments, considering the injection molding process, the first rib and the protrusion can be integrally molded, which makes the first rib "inherently" adjacent to the outer surface of the protrusion 2, i.e., extending to the outer surface of the protrusion 2. This adjacency relationship, formed by integral molding, ensures that there are no assembly gaps or weak points in the connection between the first rib and the protrusion during the molding process, and can more effectively restrain the deformation of the protrusion. When the joint is subjected to external forces, the integrally molded protrusion and the first rib can work seamlessly together to form a unified integral structure. The first rib can quickly and evenly distribute the external forces borne by the joint 10 to the protrusion 2 and the entire joint structure, avoiding local stress concentration, thereby significantly improving the overall stability and reliability of the joint. In practical applications, such as in pipe connections subjected to frequent vibration or impact loads, the close adjacency and cooperative working capability brought about by this integral molding can enable the joint to decompose axial impact forces to a large extent, ensuring the stable operation of the pipeline system.

[0085] In some embodiments, for all the first ribs 31 of the joint 10, the angle between the plane 31s of each first rib and the bottom surface of the protrusion 2 may be the same or different, and this disclosure does not impose any restrictions on this.

[0086] Now for reference Figures 3A to 3C . Figure 3A The figure shows a schematic front view of one embodiment of the connector according to the exemplary embodiments disclosed herein. Figure 3B The figure shows a schematic front view of one embodiment of the connector according to the exemplary embodiments disclosed herein. Figure 3C The figure shows a schematic top view of one embodiment of the connector according to the exemplary embodiments disclosed herein. Figure 3A or Figure 3B One of them can be rotated by a certain angle along the circumferential direction of the protrusion 2 to obtain the other.

[0087] In some embodiments, the reinforcing rib 3 may include a second rib 32, which may intersect with the first rib 31. It is understood that the first rib 31 described herein, regardless of whether it is inclined relative to the bottom surface of the protrusion 2, is generally straight. As shown, the second rib 32 may refer to a transverse component connecting these straight first ribs 31, such as a crossbeam. When the first rib 32, acting as, for example, a crossbeam, intersects with the straight first ribs 31, they together form a more robust spatial structure. In some pipe connection applications requiring enhanced overall joint stiffness, the placement of the second rib 32 can connect portions of the first ribs 31 into a single unit and integrate them together, enabling the joint 10 to better resist various complex external forces and improving the overall stability and reliability of the joint.

[0088] It is understandable that the placement of the second rib 32 can depend on the construction and performance of the injection molding machine nozzle. For example, factors such as the nozzle diameter, injection pressure, and material flowability may affect the distribution density, thickness, and shape design of the second rib 32. Furthermore, the specific location and number of the second rib 32 can be optimized and adjusted according to the product's structural strength requirements, the feasibility of the injection molding process, and the complexity of the mold design. It is also understandable that the shape and size of the second rib 32 are not specifically limited, as long as the outer surface 32os of the second rib cooperates with the outer surface 31os of the first rib, presenting an overall shape similar to the side of a specific platform (this specific platform "matches" the column of the protrusion 2, as described above). Figures 3A to 3C As shown. For example, the second rib 32 can be arc-shaped, wavy, or other geometric shapes, and its cross-section can be rectangular, trapezoidal, or irregular, as long as its outer surface 32os and the outer surface 31os of the first rib together form the required platform side profile. This design flexibility can not only meet the functional requirements of different products, but also optimize the material flow and cooling efficiency in the injection molding process, thereby improving production efficiency and product quality.

[0089] Now for reference Figure 4A and Figure 4B . Figure 4A The figure shows a schematic front view of one embodiment of the connector according to the exemplary embodiments disclosed herein. Figure 4B The figure shows a schematic top view of one embodiment of the connector according to the exemplary embodiments disclosed herein.

[0090] As can be seen from the figure, in some embodiments, the plane 32s in which the second rib 32 is located can be perpendicular to the bottom surface of the protrusion 2. In this case, similar to the straight first rib 31, the shape of the second rib 32 is flat or plate-like. Therefore, as used herein, when referring to "the plane 32s in which the second rib 32 is located," it can mean that the second rib 32 is not a non-planar shape, but is flat. Thus, the plane 32s in which the second rib 32 is located perpendicular to the bottom surface of the protrusion 2 is equivalent to the plane in which the outer side 32os of the second rib 32 or the plane in which its opposite inner side is located is perpendicular to the bottom surface of the protrusion 2.

[0091] Now for reference Figure 5A and Figure 5B . Figure 5A The figure shows a schematic front view of one embodiment of the connector according to the exemplary embodiments disclosed herein. Figure 5B The figure shows a schematic top view of one embodiment of the connector according to the exemplary embodiments disclosed herein.

[0092] As can be seen from the figure, in some embodiments, the plane containing all the first ribs 31 may not pass through the axis of the protrusion 2, which may be useful in certain specific situations. It should be noted that although the figure illustrates that the plane containing all the first ribs 31 may not pass through the axis of the protrusion 2 by taking the example that all the first ribs 31 are perpendicular to the bottom surface of the protrusion 2, it can be understood that when all the first ribs 31 are inclined relative to the bottom surface of the protrusion 2, the plane containing all the first ribs 31 also does not pass through the axis of the protrusion 2.

[0093] As can also be seen from the figures, in some embodiments, where the plane containing all the first ribs 31 does not pass through the axis of the protrusion 2, at least some of the first ribs 31 may not be parallel to each other, which may be useful in certain specific situations.

[0094] Now for reference Figure 6A and Figure 6B . Figure 6A The figure shows a schematic front view of one embodiment of the connector according to the exemplary embodiments disclosed herein. Figure 6B The figure shows a schematic top view of one embodiment of the connector according to the exemplary embodiments disclosed herein.

[0095] As can be seen from the figure, in some embodiments, the first ribs 31 can be parallel to each other when none of the planes containing the first ribs 31 pass through the axis of the protrusion 2, which may be useful in certain specific situations.

[0096] Now for reference Figure 7A and Figure 7B . Figure 7A The figure shows a schematic front view of one embodiment of the connector according to the exemplary embodiments disclosed herein. Figure 7B The figure shows a schematic top view of one embodiment of the connector according to the exemplary embodiments disclosed herein.

[0097] As can be seen from the figure, in some embodiments, the plane containing some of the first ribs 31 passes through the axis of the protrusion 2, while the plane containing the remaining first ribs 31 does not pass through the axis of the protrusion 2. This may be useful in certain specific situations. It should be noted that although the figure illustrates that the plane containing some of the first ribs 31 may not pass through the axis of the protrusion 2, assuming that all the first ribs 31 are perpendicular to the bottom surface of the protrusion 2, it is understood that in the case where some of the first ribs 31 are inclined relative to the bottom surface of the protrusion 2, the plane containing these first ribs 31 also does not pass through the axis of the protrusion 2.

[0098] As can be seen from the figures, in some embodiments, the first ribs 31 may be non-uniformly spaced apart from each other along the circumference of the protrusion 2. As used herein, when referring to "spaced," it may mean the shortest distance between the lines of intersection of each adjacent first rib 31 and the bottom surface of the protrusion 2. In some cases, the space may also refer to the longest distance between the lines of intersection of each adjacent first rib 31 and the bottom surface of the protrusion 2, etc., and this disclosure does not impose any limitations in this regard.

[0099] Of course, in other embodiments, the first ribs 31 may be evenly spaced apart from each other along the circumference of the protrusion 2.

[0100] Now for reference Figure 8A and Figure 8B . Figure 8A The figure shows a schematic front view of one embodiment of the connector according to the exemplary embodiments disclosed herein. Figure 8B The figure shows a schematic top view of one embodiment of the connector according to the exemplary embodiments disclosed herein.

[0101] As can be seen from the figure, in some embodiments, the first rib 31 can be divided into two groups (or more groups). Furthermore, the planes 31s containing the first ribs in each group are parallel to each other, and the planes 31s containing the first ribs in different groups are at an angle to each other, for example, 90 degrees, as depicted in the figure.

[0102] Now for reference Figure 9A and Figure 9B . Figure 9A The figure shows a schematic front view of one embodiment of the connector according to the exemplary embodiments disclosed herein. Figure 9B The figure shows a schematic top view of one embodiment of the connector according to the exemplary embodiments disclosed herein.

[0103] As can be seen from the figure, in some embodiments, the thickness of at least part of the first rib 31 narrows as it approaches the protrusion 2 (e.g., the outer side of the protrusion 2).

[0104] Of course, in other embodiments, at least part of the thickness of the first rib 31 increases as it approaches the protrusion 2 (e.g., the outer surface of the protrusion 2).

[0105] Now for reference Figure 10A and Figure 10B . Figure 10A The figure shows a schematic front view of one embodiment of the connector according to the exemplary embodiments disclosed herein. Figure 10B The figure shows a schematic top view of one embodiment of the connector according to the exemplary embodiments disclosed herein.

[0106] As can be seen from the figures, in some embodiments, the prism can be a prism, and the frustum can be a frustum. For example, the prism is depicted as a regular hexagonal prism, and the matching frustum is depicted as a regular hexagonal frustum. It is understood that other combinations of regular N-prisms and regular N-frustums are also conceivable, and this disclosure does not impose any limitations on them.

[0107] Now for reference Figure 11A and Figure 11B . Figure 11A The figure shows a schematic front view of one embodiment of the connector according to the exemplary embodiments disclosed herein. Figure 11B The figure shows a schematic top view of one embodiment of the connector according to the exemplary embodiments disclosed herein.

[0108] As can be seen from the figure, in some embodiments, the thickness of at least a portion of the first rib 31 narrows as it approaches the protrusion 2 (e.g., the outer side of the protrusion 2), and the thickness of at least a portion of the first rib 31 thickens as it approaches the protrusion 2 (e.g., the outer side of the protrusion 2), and the degree of narrowing of the former and the degree of thickening of the latter may not be consistent, and this disclosure does not impose any limitations on this.

[0109] It should be noted that in Figure 1, the end of the protrusion 2 of the connector away from the main body 1 is designed with a rounded transition portion 5, the main purpose of which is to facilitate the pre-alignment of the connector 10. The rounded corner design of the transition portion 5 can guide the insertion process, simplify the docking operation, and reduce the risk of damage due to misalignment. Although only the design of the rounded transition portion 5 is shown in Figure 1, those skilled in the art will understand that the designs in the other figures or their variations can also adopt a similar transition portion 5. For example, the shape of the transition portion 5 can be adjusted to an arc, a slope, or other geometric shapes according to specific application requirements, as long as it can achieve the pre-alignment function and optimize stress distribution.

[0110] In certain special cases, the stiffening design of this disclosure can also be used for oblique prisms and their matching oblique frustums. Oblique prism and oblique frustum structures are typically used in applications requiring connections at specific angles or directions. The stiffening design of this disclosure is not only applicable to traditional cylinder-frustum and regular prism-frustum structures, but can also be adapted to the geometric characteristics of oblique prisms and oblique frustums by adjusting the distribution, angle, and thickness of the stiffening ribs.

[0111] The various characteristics and properties of the first rib 31 and the second rib 32 in the exemplary embodiments described above can be combined with each other, as long as their outer surfaces 31os and 32os together form the desired side profile of the platform. For example, the thickness, distribution density, shape, and other characteristics of the first rib 31 can be arbitrarily combined with the corresponding characteristics of the second rib 32 to achieve different structural strength, material distribution, or molding process requirements. Although this document does not exhaustively list all possible variations and combinations, those skilled in the art, after reading the exemplary embodiments above, can make reasonable adjustments, substitutions, or combinations based on these exemplary embodiments without creative effort, thereby obtaining other possible implementation methods. These implementation methods, as long as they conform to the core technical idea of ​​this disclosure, namely, that the outer surfaces of the first rib 31 and the second rib 32 together form the desired side profile of the platform, should all be considered to fall within the protection scope of this disclosure. This flexible design space not only reflects the wide applicability of the technical solution of this disclosure, but also helps to meet the diverse application scenarios in actual production.

[0112] Now for reference Figure 12 and Figure 13 . Figure 12 The figure shows a schematic perspective view of a novel connector design according to exemplary embodiments disclosed herein. Figure 13 The figure shows a schematic perspective view of a joint design employing an integral column-tablet structure according to exemplary embodiments disclosed herein.

[0113] From an aesthetic perspective, the novel connector design disclosed in this paper could involve grooves carved into the platform of a one-piece column-platform structure, with the grooves reaching a depth similar to the outer surface of the column extending downwards to the bottom of the platform. Although Figure 12 The novel connector design shown demonstrates Figure 1A and Figure 1B The connector 10 shown is understandable; see reference. Figures 2A to 11B The joints and their variations described in either of these can also be considered as joints designed with an integral column-table structure, with corresponding grooves made in the tabletop.

[0114] In addition to injection molding and grooving, any of the connectors disclosed herein can be produced by methods such as extrusion molding and additive manufacturing (e.g., 3D printing), and the size of the connector can vary depending on the application scenario of the pipeline connection, without any limitation in this disclosure.

[0115] Now for reference Figure 14 and Figure 15 . Figure 14 This is an image showing the porosity test results of a novel connector design according to exemplary embodiments disclosed herein. Figure 15 This is an image showing the porosity test results of a joint design employing an integral column-tablet structure according to exemplary embodiments disclosed herein.

[0116] Figure 14 and Figure 15 Pore ​​test results are presented comparing the novel joint design according to the exemplary embodiments disclosed herein with those of a conventional one-piece column-to-tablet structure joint design. From Figure 14 As can be seen, the novel joint design significantly reduces the formation of internal pores during the manufacturing process, while Figure 15 This reveals a large number of pores within the integrated joint structure, typically caused by uneven material flow or cooling shrinkage during injection molding. The novel joint design, through optimized structural design and manufacturing processes, effectively avoids or reduces the formation of pores within the joint, thus demonstrating significant advantages in several aspects.

[0117] First, by adding reinforcing ribs, the novel joint design significantly reduces component weight and saves production costs, making it particularly suitable for weight-sensitive applications such as aerospace and automotive manufacturing. Second, reduced porosity lowers the scrap rate caused by porosity, further saving production costs. Furthermore, the novel joint design reduces porosity formation caused by cooling contraction or gas retention in uniform thickness designs, improving product quality consistency. Simultaneously, reduced porosity significantly improves the joint's structural stability, enabling it to better resist deformation during insertion and subsequent use, which is especially important for applications requiring high-precision mating. Finally, by reducing porosity, the novel joint design improves material density and uniformity, significantly enhancing the joint's axial compressive strength, allowing it to withstand greater loads. (Comparison...) Figure 14 and Figure 15 The porosity test results clearly demonstrate the significant advantages of the novel connector design in reducing porosity. Figure 14 The internal structure of the joint is uniform and dense, with almost no obvious pores. Figure 15The integrated joint exhibits numerous irregularly distributed pores. This difference not only validates the effectiveness of the novel joint design but also provides evidence for its performance advantages in practical applications. The disclosed novel joint design, through optimized structural design and manufacturing processes, effectively avoids or reduces the formation of pores within the joint, thus demonstrating significant advantages in reducing component weight, saving costs, improving production processes, increasing component stability, and enhancing axial compressive strength. These advantages improve product performance and reliability.
