[0031] Figure 1 This is a schematic diagram of the structure of a connector locking nut provided by an embodiment of the utility model. Figure 2 is a cross-sectional schematic diagram of a connector locking nut provided by an embodiment of the utility model, combined with Figure 1 and Figure 2 As shown, the connector locking nut A includes a metal part 1 and an injection molded part 2 that is formed by an insert molding process and wraps the metal part 1. It should be noted that after the metal part 1 is processed, it is installed in a predetermined position in the mold cavity as an insert, and then the mold is closed for injection molding so that the molten plastic fills the cavity space outside the metal part 1, so that the plastic material forms the injection molded part 2 after solidification and becomes one with the metal part 1. It is easy to understand that when the metal part 1 and the injection molded part 2 are combined by injection molding, the molten plastic can be fully filled into the cavity space, thereby ensuring the bonding strength between the metal part 1 and the injection molded part 2. Furthermore, a threaded hole 11 is provided on the metal part 1, and the injection molded part 2 exposes the threaded hole 11, so that the connector locking nut A can achieve the installation locking function through the threaded hole 11. Furthermore, Figure 3 It is a partial structural schematic diagram of an application scenario of a connector locking nut provided by an embodiment of the utility model. Figure 4 This is a partial cross-sectional schematic diagram of an application scenario of a connector locking nut provided by an embodiment of the utility model, combined with Figures 1 to 4 As shown, the connector locking nut A can be used to install and lock the connector B on the installation panel C through the threaded hole 11.
[0032] Combination Figure 1 and Figure 2As shown, in one embodiment, the metal part 1 is set to a right prism structure. It is easy to understand that the metal part 1 can be made of a rod or profile with a right prism structure, so that the material is not easy to produce coaxial rotation when processing the thread feature, thereby avoiding the waste of material caused by thread processing deviation and saving machining time. It should be noted that the cross-section of the metal part 1 in this embodiment is hexagonal, that is, the metal part 1 is processed from a metal material in the shape of a hexagonal prism. As an optional embodiment, the cross-section of the metal part 1 can also be an octagon or other polygon, that is, the metal part 1 is processed from an octagonal or other prism metal material. As another optional embodiment, the cross-section of the metal part 1 can also be circular, elliptical, fan-shaped or various irregular shapes, and the metal part 1 is processed from a rod or profile of a corresponding shape. Further, the threaded hole 11 runs from the top of the metal part 1 to the bottom of the metal part 1, so that the metal part 1 is formed into a ring shape, so that the connector locking nut A formed subsequently is sleeved on the connector B for installation and locking. It is easy to understand that the metal part 1 can be made of a hollow rod, that is, a tubular rod, so that the machining time can be further saved, which helps to improve the production efficiency of the connector locking nut A. In addition, the metal part 1 does not need to be subjected to additional cutting processing (for example, it does not need to be formed into the shape of a flange nut by cutting), and it is not necessary to select a metal rod according to the required maximum size and process it into the required shape, thereby saving the raw material cost and processing cost of the metal rod.
[0033] Combination Figure 1 and Figure 2 As shown, in one embodiment, the injection molded part 2 includes a main body 21. Specifically, the main body 21 extends outward from the outer side wall of the metal part 1, and the top of the main body 21 is flush with the top of the metal part 1. As a result, the main body 21 can wrap the outer side wall of the metal part 1 to achieve a tight combination with the metal part 1, and the main body 21 will not block the threaded hole 11 on the metal part 1, so as to ensure that the connector locking nut A can install and lock the connector B through the threaded hole 11. As an optional embodiment, the top of the main body 21 can cover the end face of the top of the metal part 1 and expose the threaded hole 11 by setting a avoidance hole. At the same time, the bottom of the main body 21 can cover the end face of the bottom of the metal part 1 and expose the threaded hole 11 by setting a avoidance hole. Therefore, in order to cope with different outdoor working environments, suitable materials can be selected for injection molding without the need for additional surface treatment of the metal part 1.
[0034] Combination Figure 1 and Figure 2As shown, in one embodiment, the main body 21 is set as a right prism structure. It is easy to understand that after the metal part 1 is processed, it is installed as an insert in a predetermined position in the right prism cavity of the mold, and then the mold is closed for injection molding so that the molten plastic fills the right prism cavity space outside the metal part 1, so that the plastic material solidifies to form a right prism main body 21 and becomes one with the metal part 1. As a result, the connector locking nut A formed by the combination of the metal part 1 and the injection molded part 2 is formed as a right prism structure as a whole. It should be noted that in this embodiment, the cross section of the main body 21 is hexagonal, that is, the cross section of the connector locking nut A is hexagonal, so that the connector locking nut A can be tightened by a tool such as a wrench, thereby ensuring the locking effect of the connector locking nut A on the connector B. As an optional embodiment, the cross section of the main body 21 can also be set to an octagon or other polygon as needed, that is, the cross section of the connector locking nut A is set to an octagon or other polygon. Figure 5 is a schematic diagram of the structure of another connector locking nut provided by an embodiment of the utility model, such as Figure 5 As shown, the cross section of the main body 21 is set to be a pentagon, and the connector locking nut A is a straight prism structure with a pentagonal cross section. Figure 1 and Figure 5 As shown, the cross section of the main body 21 is set to a regular polygon such as a regular hexagon or a regular pentagon, so that the connector locking nut A is formed into a regular prism structure, so that the connector locking nut A is adapted to installation tools such as a wrench during subsequent installation. As another optional embodiment, the cross section of the main body 21 can also be circular, elliptical, fan-shaped or various irregular shapes, so that the connector locking nut A can be set to a corresponding right prism shape according to actual needs.
[0035] like Figure 5 As shown, in one embodiment, a chamfer 211 is provided at the side edge of the main body 21. It is easy to understand that by providing the chamfer 211, it is helpful to tighten the connector locking nut A with a practical wrench or other installation tools, which can prevent the edges of the main body 21 from being scratched and generating debris during installation, and at the same time, it can also prevent the edges of the main body 21 from scratching the equipment installed with the connector B and causing product defects. It should be noted that as an optional embodiment, the threaded hole 11 can also be chamfered, which on the one hand helps to smoothly screw the connector locking nut A into the predetermined position, thereby shortening the installation time and improving the installation efficiency, and on the other hand, it can also avoid damaging the threaded structure or the connector B during the installation process, thereby ensuring the normal service life of the connector locking nut A and the connector.
[0036] Figure 6 This is a structural schematic diagram of another connector locking nut provided by an embodiment of the utility model. Figure 7This is a cross-sectional schematic diagram of another connector locking nut provided by an embodiment of the utility model, combined with Figures 5 to 7 As shown, in one embodiment, the injection molded part 2 is further provided with a flange portion 22 on the basis of the main body 21. Specifically, the flange portion 22 extends outward from the bottom end of the main body 21. It is easy to understand that the injection molded part 2 can increase the contact area between the connector locking nut A and the mounting panel C by forming the flange portion 22, thereby increasing the surface friction between the connector locking nut A and the mounting panel C, and further enhancing the locking effect of the connector locking nut A on the connector B. In addition, the connector locking nut A can also further distribute the pressure of the connector locking nut A after installation on the mounting panel C by setting the flange portion 22, thereby reducing the possibility of the mounting panel C being damaged by pressure. It should be noted that in this embodiment, the flange portion 22 is formed in a circular shape. As an optional embodiment, the flange portion 22 can also be set to other shapes such as a triangle, a square, a fan, etc. as needed.
[0037] Combination Figure 1 and Figure 2 As shown, in one embodiment, the threaded hole 11 is located at the center of the metal member 1. Furthermore, the thickness of the side walls at different positions of the main body 21 is equal. Specifically, corresponding to the metal member 1 with a regular hexagonal cross-section, the cross-section of the main body 21 is also set to a regular hexagon, and each outer side wall of the main body 21 is parallel to the corresponding outer side wall on the metal member 1. In other words, the main body 21 is formed into a tubular structure with uniform wall thickness and equal thickness everywhere. Based on this, it is easy to understand that the threaded hole 11 is relatively located at the center of the connector locking nut A, so that the connector locking nut A is formed as a central symmetrical structure as a whole. Therefore, when the connector locking nut A locks the connector B, the various parts of the connector locking nut A are evenly stressed, thereby reducing the risk of pressure damage to the connector locking nut A.
[0038] It should be noted that, as an optional implementation, the thickness of the side walls at different positions of the main body 21 may also be different, as long as the main body 21 can wrap the metal part 1. Figure 6 and Figure 7As shown, the cross-section of the metal part 1 is a regular hexagon, while the cross-section of the main body 21 is a regular octagon. That is to say, the main body 21 is formed into a tubular structure with uneven wall thickness. In the production process of the connector locking nut A in the above example, it is only necessary to place the processed metal part 1 into the predetermined position in the mold, and the angle of the metal part 1 needs to be further restricted or adjusted, thereby reducing the production operation steps and improving production efficiency. It should be further explained that based on the threaded hole 11 being located at the center position of the metal part 1, the metal part 1 is also placed in the center position of the mold after processing is completed, so that the threaded hole 11 of the metal part 1 after injection molding is also located at the center position of the connector locking nut A, so that the connector locking nut A can be rotated and screwed into the predetermined installation position during the installation process.
[0039] In one embodiment, the material of the metal part 1 is copper alloy or aluminum alloy. On the one hand, both copper alloy and aluminum alloy can meet the strength requirements of the connector locking nut A. Specifically, both copper alloy and aluminum alloy can easily process thread features, and on this basis, it can also ensure that the connector locking nut A reduces wear and prevents loosening, so that the fastening ability of the connector locking nut A is stronger, thereby ensuring that the connector B can work stably for a long time. On the other hand, both copper alloy and aluminum alloy have good thermal conductivity. Specifically, when the metal part 1 is processed and placed in the mold, it is necessary to inject plastic in a high-temperature molten state into the mold, and the metal part 1 is also in a high-temperature state. Further, after the injection molding is completed, the injection molded part 2 is rapidly cooled and hardened, and the metal part 1 made of copper alloy or aluminum alloy is also cooled synchronously, avoiding the slow cooling of the metal part 1 resulting in excessive temperature difference with the injection molded part 2, which causes the position where the injection molded part 2 contacts the metal part 1 to loosen or crack, thereby ensuring the connection strength between the injection molded part 2 and the metal part 1, and then the fastening strength of the connector locking nut A to the connector B can be improved.
[0040] In one embodiment, the material of the injection molded part 2 is UV-resistant plastic. Exemplarily, the material of the injection molded part 2 is modified resin (ASA) with UV-resistant agent, polybutylene terephthalate (PBT), polycarbonate (PC), nylon (PA), etc. Therefore, the use requirements of the connector locking nut A in outdoor environments can be met by the injection molded part 2 with UV-resistant ability, which helps to avoid the problem of surface corrosion and improves the reliability of the connector locking nut A, thereby ensuring that the connector B can work stably for a long time. It should be noted that, as an optional embodiment, when the connector locking nut A does not need to be used in an outdoor environment, the injection molded part 2 can also be made of plastic without UV-resistant agent, such as modified resin (ASA) without UV-resistant agent, polybutylene terephthalate (PBT), polyoxymethylene (POM), polycarbonate (PC), nylon (PA), acrylic (PMMA), polyethylene (PE), etc., which helps to reduce costs.
[0041] The embodiment of the utility model also provides a communication device. It should be noted that the communication device includes but is not limited to a base station antenna. Further, Figure 3-4 As shown, the communication device includes a connector locking nut A, a connector B and a mounting panel C. Among them, the specific structure of the connector locking nut A is as described above and will not be repeated here. Furthermore, the connector B is a radio frequency connector, which is installed on the mounting panel C of a thin plate-like structure. It should be noted that in this embodiment, the mounting panel C is rectangular and is installed with 4 connectors B. Optionally, the mounting panel C can also be set to other shapes and other numbers of connectors B can be installed according to the specific structure of the communication device. It is easy to understand that the communication device installs and locks the connector B through the connector locking nut A, which helps to reduce material costs and processing costs. At the same time, the threaded hole 11 is set on the metal part 1 to ensure the reliability of the threaded connection, and the use of the injection molded part 2 on the periphery can reduce the risk of product inter-adjustment that may be caused by large pieces of metal materials, thereby ensuring the reliability of the communication equipment. In addition, the use of the injection molded part 2 on the periphery can easily adjust the appearance color, which helps to better meet market demand while ensuring the installation and locking effect.
[0042] The embodiment of the utility model provides a connector locking nut and a communication device, wherein the connector locking nut comprises a metal part and an injection molded part formed by an insert injection molding process and wrapping the metal part. The metal part is provided with a threaded hole, and the injection molded part exposes the threaded hole, so that the connector locking nut can lock the connector. Thus, the connector locking nut reduces material cost and processing cost, and helps to improve production efficiency.
[0043] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
