[0039] The specific embodiments of the present application have been shown by way of example in the above figures, and will be described in more detail hereafter. These figures and the written description are not to be construed as limiting the scope of the inventive concept in any way, but are merely to illustrate specific embodiments of the inventive concept by reference to specific embodiments. DETAILED DESCRIPTION
[0040] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The description of the exemplary embodiments is intended to apply to any embodiment of the application, unless specified otherwise. It should be understood that every embodiment need not necessarily include all of the features shown in the drawings or all of the components described in the specification. The exemplary embodiments described herein are intended to be illustrative of the application and not in a limiting sense.
[0041] The optical cable joint box is a kind of optical cable to the house facility, mainly used for protective connection between two or more optical cables, optical fiber distribution, is one of the user access point commonly used equipment, mainly completes the connection of distribution optical cable and indoor optical cable in the outdoor, and can be installed according to the needs of FTTX access box type or simple type shunt.
[0042] The design form of the optical cable joint box includes cap type and box type. Among them, the traditional cap type joint box usually includes a base, a cap body and a clamp, the cap body is inserted on the base, and then the clamp is fixed at the connection between the base and the cap body, so as to realize the connection and fixation of the base and the cap body.
[0043] However, the design of the clamp connection of the traditional cap type joint box is relatively limited in the size of the clamp. Specifically, the locking and sealing effect depends on the size design of the clamp slot. If the size of the slot is designed too large, the base and the cap body cannot be pressed tightly, and the sealing effect cannot meet the requirements. If the size of the slot is designed too small, the clamp will be difficult to install or even cannot be installed when clamping the base and the cap body.
[0044] In addition, the quality of the clamp will directly affect the fixing effect of the base and the cap body. The product quality of the clamp directly affects the overall product quality. Once the clamp is damaged, the base and the cap body cannot be fixed, resulting in poor fixing effect. In addition, this fixing method is easy to be opened by non-professionals or maliciously opened, and the safety cannot be guaranteed.
[0045] Therefore, the optical cable joint box provided by the embodiment of the present application is designed with a connecting structure and a matching structure, the connection of the cap body and the base is realized through the mutual cooperation of the connecting structure and the matching structure, when the cap body is sleeved outside the connecting portion, the connecting structure and the matching structure will be mutually engaged or locked, thereby ensuring the stable connection between the two. The connection mode is stable and reliable, and is easy to operate and maintain. Compared with the traditional connection mode, the connection of the cap body and the base no longer depends on additional fixing members such as hoops, thereby simplifying the installation process and reducing the cost, avoiding the dependence of the optical cable joint box on the fixing members such as hoops, and improving the overall quality and safety.
[0046] It can be seen that the optical cable joint box of the embodiment realizes the stable connection of the base and the cap body without affecting the space capacity and splicing function of the existing joint box through the innovative connecting structure and matching structure, the design improves the applicability and reliability of the joint box, and makes the operation and maintenance more convenient, and reduces the possibility of non-professional personnel mistakenly opening the optical cable joint box.
[0047] The following will be described in detail Figures 1 to 3 The optical cable joint box of the embodiment of the first aspect of the present application is described.
[0048] In combination Figures 1 to 3 The optical cable joint box of the embodiment can be a cap-type joint box for splicing and fiber splitting in optical communication engineering construction lines, and is not limited to the structure and scene of the optical cable.
[0049] The optical cable joint box can be formed by injection molding, and the material can be PP / GF (enhanced polypropylene material), PC (polycarbonate), ABS (acrylonitrile-butadiene-styrene), and some metal materials such as aluminum alloy and stainless steel.
[0050] The optical cable joint box of the embodiment includes a base 100 and a cap body 200. The base 100 includes a threading portion 110 and a connecting portion 120 distributed and connected along the axial direction thereof, and the base 100 is further provided with a threading channel 130 penetrating through the threading portion 110 and the connecting portion 120, the threading channel 130 being used for threading through an optical cable, which ensures that the optical cable can smoothly enter the inside of the joint box for necessary connection or protection. The connecting portion 120 is provided with a connecting structure 300 for cooperating with a matching structure 400 on the cap body 200 to realize the connection and fixation of the two.
[0051] Optionally, a plurality of resistance strips can be designed outside the cap body 200, the plurality of resistance strips being sequentially and spacedly arranged on the shell of the cap body 200 in the axial direction, or the plurality of resistance strips being cross arranged to ensure the strength and anti-skid performance thereof.
[0052] The cap body 200 defines an accommodation cavity 210 with one end open, and the accommodation cavity 210 is used for accommodating and protecting the optical cable connecting portion 120 or other components that need to be protected.
[0053] The cavity wall of the accommodating cavity 210 is provided with a matching structure 400, which enables the cap body 200 to be tightly sleeved on the outside of the connecting part 120 and stably connected with the base 100. The cap body 200 is sleeved on the outside of the connecting part 120, and the cap body 200 and the connecting seat are connected through the connecting structure 300 and the matching structure 400.
[0054] Specifically, the connection between the cap body 200 and the base 100 is realized through the mutual cooperation of the connecting structure 300 and the matching structure 400. When the cap body 200 is sleeved on the outside of the connecting part 120, the connecting structure 300 and the matching structure 400 will be engaged or locked with each other, thereby ensuring the stable connection between the two. This connection mode is stable and reliable, easy to operate and maintain. Compared with the traditional connection mode, the connection between the cap body 200 and the base 100 no longer relies on additional fixing members such as a clamp, thereby simplifying the installation process and reducing the cost, avoiding the dependence of the optical cable joint box on the fixing members such as the clamp, and improving the overall quality and safety.
[0055] As can be seen, the optical cable joint box of the embodiment realizes the stable connection between the base 100 and the cap body 200 without affecting the space capacity and splicing function of the existing joint box through the innovative connecting structure 300 and the matching structure 400. This design improves the applicability and reliability of the joint box, and makes the operation and maintenance more convenient, and reduces the possibility of non-professionals mistakenly opening the optical cable joint box.
[0056] In some embodiments, in combination with Figure 2 and Figure 3 The connecting structure 300 is a connecting thread, the matching structure 400 is a matching thread, and the cap body 200 is threadedly connected with the connecting part 120.
[0057] Optionally, the connecting part 120 is designed with external threads, and the accommodating cavity 210 of the cap body 200 is provided with internal threads matched with the external threads. This design enables the cap body 200 to be tightly sleeved on the outside of the connecting part 120 and stably connected through the rotation and engagement of the threads.
[0058] Specifically, when the cap body 200 is placed on the outside of the connecting part 120, the internal threads and the external threads start to contact each other. By rotating the cap body 200, the internal threads and the external threads will gradually engage along the pitch direction until the desired fastening degree is reached. This thread cooperation mode not only provides stable connection, but also has certain sealing performance, which can prevent external environment from interfering with the inside of the joint box.
[0059] By adopting the design of the connecting thread and the mating thread, the optical cable joint box of the embodiment realizes the threaded connection between the cap body 200 and the connecting part 120. This connection method is not only stable and reliable, but also easy to operate and maintain. At the same time, the threaded connection also has a certain sealing performance, which can ensure that the optical cable connecting part 120 inside the joint box is not disturbed by the external environment.
[0060] In some embodiments, the number of threads a of the mating thread and the number of threads b of the connecting thread satisfy: a-b≥1.
[0061] It can be understood that when the number of threads a of the mating thread is greater than the number of threads b of the connecting thread, it means that after the cap body 200 is rotated in place, at least one turn of the mating thread and the connecting thread will be in a biting state. This design increases the stability of the connection, reduces the impact of the external environment on the joint box when a certain vibration or impact is exerted on the joint box, and the biting between the threads can still be maintained and is not easy to loosen.
[0062] In addition, the threaded connection also has a certain sealing effect. When the number of threads of the mating thread is greater than that of the connecting thread, more thread areas will participate in sealing, thereby improving the sealing performance of the joint box.
[0063] It can be seen that by ensuring that the number of threads a of the mating thread is greater than or equal to the number of threads b of the connecting thread plus 1 (i.e., a-b≥1), the stable connection of the optical cable joint box is ensured, and the sealing performance of the optical cable joint box is also improved.
[0064] In some embodiments, in combination with Figure 1 and Figure 2 , the base 100 further comprises a flange part 500, the threading part 110 and the connecting part 120 are located on both sides of the flange part 500, the threading channel 130 also penetrates the flange part 500, and the cap body 200 abuts the flange part 500 in the axial direction.
[0065] The flange part 500 is arranged between the threading part 110 and the connecting part 120, and plays a connecting and supporting role, providing a stable base for the threading part 110 and the connecting part 120, and also helping to enhance the overall structural strength of the joint box. In addition, the threading channel 130 is also designed to penetrate the flange part 500, ensuring that the optical cable can smoothly pass through the entire base 100 and enter the joint box for connection or protection.
[0066] When the cap body 200 is sleeved outside the connecting part 120 and rotated in place, the cap body 200 will abut the flange part 500 in the axial direction. This design helps to enhance the sealing performance of the joint box, and the contact surface between the cap body 200 and the flange part 500 can form an additional sealing barrier.
[0067] The projection of the threading portion 110 in the reference plane is within the projection of the flange portion 500 in the reference plane, and the projection of the connecting portion 120 in the reference plane is within the projection of the flange portion 500 in the reference plane, where the reference plane is perpendicular to the axial direction of the base 100.
[0068] It can be understood that the reference plane is a plane perpendicular to the axial direction of the base 100, which is used to describe the projection relationship of the threading portion 110, the connecting portion 120, and the flange portion 500 in the plane. The projection of the threading portion 110 in the reference plane is completely within the projection of the flange portion 500 in the reference plane, and the projection of the connecting portion 120 in the reference plane is also completely within the projection of the flange portion 500 in the reference plane, which means that the flange portion 500 completely covers the threading portion 110 and the connecting portion 120 in the transverse direction, providing a protective shell for them.
[0069] By introducing the flange portion 500 and ensuring that the projections of the threading portion 110 and the connecting portion 120 in the reference plane are completely within the projection of the flange portion 500, the stability and sealing performance of the joint box are enhanced, and the optical cable connecting portion 120 is also protected from external environmental interference. The design of the flange portion 500 provides a stable base and support structure for the threading portion 110 and the connecting portion 120, improving the overall reliability and durability of the joint box.
[0070] In some embodiments, in combination Figure 2 The optical cable joint box further comprises a sealing ring 600, which is sleeved on the outside of the connecting portion 120 and is in close contact with the flange portion 500; and the cap body 200 is further covered on the outside of the sealing ring 600.
[0071] Optionally, the sealing ring 600 can be an O-shaped sealing ring 600.
[0072] The sealing ring 600 is designed to be sleeved on the outside of the connecting portion 120 and in close contact with the flange portion 500. The sealing ring 600 is mainly used to provide an additional sealing barrier to prevent external pollutants such as water and dust from entering the joint box through the gap between the connecting portion 120 and the cap body 200.
[0073] Optionally, the material of the sealing ring 600 can be rubber, silicone, or polyurethane, etc. These materials have good elasticity and sealing performance, and can tightly fit on the flange portion 500 and the connecting portion 120 when subjected to pressure, forming an effective seal.
[0074] The sealing ring 600 is placed on the outside of the connecting portion 120 during installation and gradually fits with the flange portion 500 as the cap body 200 rotates. Once the cap body 200 is rotated into place, the sealing ring 600 is compressed and tightly fits between the flange portion 500 and the connecting portion 120, forming a stable seal.
[0075] In addition, the cap 200 is also arranged on the outer side of the sealing ring 600, which ensures that the sealing ring 600 can be effectively compressed and tightly fitted between the flange part 500 and the connecting part 120 when subjected to pressure, further enhancing the sealing performance of the joint box.
[0076] By introducing the sealing ring 600 and designing the cap 200 to cover the outer side of the sealing ring 600, it helps to prevent external pollutants from entering the joint box, and also improves the overall reliability and durability of the joint box.
[0077] In some embodiments, in combination with Figure 2 and Figure 3 The side of the flange part 500 facing the connecting part 120 is also provided with circumferentially distributed anti-rotation structures 710, and the cap 200 is provided with anti-rotation cooperation structures 720 matched with the anti-rotation structures 710. When the cap 200 is installed in place, the anti-rotation structures 710 and the anti-rotation cooperation structures 720 are limitedly matched.
[0078] The anti-rotation structures 710 are arranged on the side of the flange part 500 facing the connecting part 120 and are circumferentially distributed. Optionally, the anti-rotation structures 710 can be designed as protrusions, grooves, buckles or other forms of limiting devices for preventing the cap 200 from rotating or loosening after being installed in place.
[0079] The anti-rotation structures 710 are at least one, and according to actual needs, multiple anti-rotation structures 710 can be designed and uniformly distributed circumferentially on the flange part 500. Multiple anti-rotation structures 710 can provide stronger limiting effect, further ensuring the stable installation of the cap 200.
[0080] In addition, the cap 200 is provided with anti-rotation cooperation structures 720 matched with the anti-rotation structures 710, which can be grooves matched with protrusions, protrusions matched with grooves, buckling grooves matched with buckles or other forms of limiting devices.
[0081] In this way, when the cap 200 is installed in place, the anti-rotation structures 710 and the anti-rotation cooperation structures 720 will engage or lock with each other, thereby limiting the rotation or loosening of the cap 200. This limiting cooperation not only enhances the stability of the joint box, but also improves the reliability and durability of the installation.
[0082] When installing the cap 200, the user needs to align the cap 200 with the connecting part 120 and rotate it into place. As the cap 200 rotates, the anti-rotation matching structure 720 will gradually come into contact with and engage with the anti-rotation structure 710. When the cap 200 is rotated to the preset position, the anti-rotation structure 710 and the anti-rotation matching structure 720 will be fully engaged, thereby limiting the rotation or loosening of the cap 200, thus realizing the anti-rotation function of the optical cable joint box.
[0083] When the cap 200 needs to be disassembled, the user needs to overcome the limiting action between the anti-rotation structure 710 and the anti-rotation matching structure 720. It may be necessary to release the limiting device by a specific tool, method or external force in order to remove the cap 200 from the connecting part 120.
[0084] By introducing the anti-rotation structure 710 and the corresponding anti-rotation matching structure 720, it helps to prevent the cap 200 from rotating or loosening after being installed in place, and also improves the overall performance and durability of the joint box. In addition, it also increases the applicability of the joint box, making it able to adapt to different environments and application scenarios.
[0085] In some embodiments, in combination Figure 2 The anti-rotation structure 710 includes a first side surface 711 and a second side surface 712 arranged in sequence along the tightening direction of the cap 200, the first side surface 711 is a bevel, and the second side surface 712 has an included angle with the first side surface 711 and a smooth transition between them; the anti-rotation matching structure 720 is formed as a matching groove 721.
[0086] Specifically, the anti-rotation structure 710 includes a first side surface 711 and a second side surface 712 arranged in sequence along the tightening direction of the cap 200, wherein the first side surface 711 is designed as a bevel, so that it will gradually come into contact with and generate extrusion force with the anti-rotation matching structure 720 during the tightening process of the cap 200. The second side surface 712 has an included angle with the first side surface 711 and a smooth transition between them, to ensure that the cap 200 can move smoothly during the tightening process and gradually fully engage with the anti-rotation matching structure 720.
[0087] The design of the bevel allows the first side surface 711 to gradually come into contact with the matching structure 400 during the tightening of the cap 200 and gradually increase the extrusion force, which helps to firmly fix the cap 200 on the connecting part 120. The design of the second side surface 712 ensures that the cap 200 can fully engage with the matching structure 400 after being fully tightened, thereby preventing the cap 200 from rotating or loosening. The design of the smooth transition reduces the friction and resistance of the cap 200 during the tightening process, making the installation process smoother.
[0088] The anti-rotation cooperation structure 720 is formed as a cooperation groove 721 which matches the geometry of the anti-rotation structure 710. The cooperation groove 721 is designed to allow the cap body 200 to gradually contact and engage with the anti-rotation structure 710 during the tightening process, thereby ensuring the secure installation of the cap body 200.
[0089] In this way, during the installation process, the user only needs to align the cap body 200 with the connecting part 120 and rotate in the tightening direction. As the cap body 200 rotates, the first side surface 711 of the anti-rotation structure 710 will gradually come into contact with the cooperation groove 721 and generate a pressing force until the second side surface 712 fully engages with the cooperation groove 721. During the disassembly process, the user can overcome the engagement between the anti-rotation structure 710 and the cooperation groove 721 by applying force, thereby removing the cap body 200 from the connecting part 120.
[0090] It can be seen that by introducing the first side surface 711 and the second side surface 712 and the matching cooperation groove 721 design, it helps to prevent the cap body 200 from rotating or loosening after installation, and also improves the overall performance and durability of the joint box. In addition, this limiting cooperation also increases the applicability of the joint box, making it able to adapt to different environments and application scenarios.
[0091] In some embodiments, in combination Figure 2 The anti-rotation structure 710 and the connecting part 120 are arranged radially apart along the base 100 and together define an installation gap; the sealing ring 600 is clamped in the installation gap.
[0092] It can be understood that the anti-rotation structure 710 and the connecting part 120 are arranged radially apart along the base 100, and thus there is a certain distance between them, not directly adjacent. This arrangement helps to form a space or gap between the anti-rotation structure 710 and the connecting part 120 for accommodating other components, such as the sealing ring 600.
[0093] The anti-rotation structure 710 and the connecting part 120 together define an installation gap, the size and shape of which are determined according to the design of the sealing ring 600 to ensure that the sealing ring 600 can be correctly installed and fixed in this position.
[0094] The sealing ring 600 is designed to be clamped in the installation gap between the anti-rotation structure 710 and the connecting part 120, and this installation method ensures that the sealing ring 600 can tightly fit on the anti-rotation structure 710 and the connecting part 120 when subjected to pressure, forming an effective seal.
[0095] By introducing the installation gap to accommodate the sealing ring 600, and arranging the anti-rotation structure 710 and the connecting portion 120 along the radial direction of the base 100, the sealing performance and stability of the optical cable joint box are improved, which helps to prevent external pollutants from entering the inside of the joint box, and also improves the overall reliability and durability of the joint box.
[0096] In some embodiments, in combination with Figure 1 、 Figure 3 and Figure 4 , the outer side wall of the cap 200 is further provided with circumferentially distributed screw teeth 800, which are used to cooperate with the teeth on the installation tool 10 and fasten the cap 200 to the connecting portion 120 under the drive of the installation tool 10.
[0097] For example, the form of the screw teeth 800 can refer to Figure 1 However, the shape and design are not limited to the illustrated scheme, and all structures that are beneficial to auxiliary locking can replace the illustrated scheme.
[0098] The screw teeth 800 are arranged on the outer side wall of the cap 200 and distributed circumferentially, which ensures that the screw teeth 800 can fully contact the teeth on the installation tool 10 and provide stable driving force.
[0099] The screw teeth 800 are mainly used to cooperate with the teeth on the installation tool 10. When the installation tool 10 is used, the teeth will engage with the screw teeth 800 on the cap 200, so that the cap 200 can be rotated together when the installation tool 10 is rotated. This design makes the fastening process of the cap 200 more convenient and efficient, which can be quickly completed by the installation tool 10.
[0100] Optionally, the screw teeth 800 can be made of hard material to ensure that they can maintain sufficient strength and wear resistance during use. For example, the material of the screw teeth 800 can be metal, hard plastic, etc.
