Description

Technical Field

[0001] This utility model relates to the field of communication base station technology, and in particular to a protective cover, adapter box and base station. Background Technology

[0002] A junction box is a connection device used to extend and split signals, providing users with an easy-to-install and maintain combination connection solution. Junction boxes are typically installed on walls or communication towers. Due to their long-term outdoor location and harsh environment, prolonged exposure to sun, rain, and bird droppings can easily contaminate cable connections and cause seal failures, leading to leakage and affecting the stability of the junction box's optical and electrical performance. Therefore, in the construction of communication base stations and communication network projects, regular routine inspections of base stations and cable connections are necessary.

[0003] Existing junction boxes generally consist of a box body and a protective cover, which are connected by multiple screws. Each time staff inspect the cables inside the junction box, they need to remove all the screws, causing inconvenience and significantly reducing maintenance efficiency. Therefore, Chinese utility model patent CN 211830065 U, with an authorization announcement date of October 30, 2020, discloses a limiting structure, a junction box, and a 5G base station. The limiting structure includes a limiting latch, a rotating connector, and a locking component. The limiting latch is located on a first cover; the locking component is rotatably mounted on a second cover, and one end of the rotating connector is rotatably mounted on the locking component. The limiting latch is fixedly latched within the rotating connector. When the locking component rotates to its dead point connected to the limiting latch, the limiting structure reaches a strongly pressed, self-locking state, causing the first and second covers to close together. Rapid opening and closing is achieved by rotating the locking component.

[0004] When the locking member of the aforementioned limiting structure rotates to the rotation dead point connected to the limiting snap-fit ​​member, the end of the locking member is easily subjected to external force and rotates back, causing the rotating connector to disengage from the limiting snap-fit ​​member, which in turn causes the first cover and the second cover to lose their locking force. Moreover, there are many connecting parts and the structure is complex. Utility Model Content

[0005] To address the shortcomings in the aforementioned background technology, this utility model proposes a protective cover, an adapter box, and a base station, which solves the technical problem that the opening and closing structure between the protective cover and the box body of the adapter box installed on the base station in the prior art is complex and the locking is unreliable.

[0006] The technical solution of this application is as follows:

[0007] A protective cover has a hinge structure for connecting electrical fasteners, and the protective cover also has at least one of a resilient snap-fit ​​structure, a screw structure, and a plug-in structure, wherein the resilient snap-fit ​​structure, screw structure, and plug-in structure are used for locking connection with the electrical fasteners.

[0008] Preferably, the protective cover is provided with limiting structures on both sides, and the limiting structures include a first stopping surface for blocking in a first direction with the electrical fastener and a second stopping surface for blocking in a second direction with the electrical fastener.

[0013] Preferably, the hinge structure includes a matching through hole II and a rotating shaft for connection with a hole in an electrical fastener.

[0014] Preferably, the protective cover is provided with mounting ears, and the hinge structure is provided on the mounting ears.

[0015] An adapter box includes an electrical fastener and a protective cover. The protective cover is rotatably connected to the electrical fastener via a hinge structure and is locked to the electrical fastener via at least one of an elastic snap-fit ​​structure, a screw connection structure, and a plug-in structure. The locked connection between the electrical fastener and the protective cover forms a cavity for accommodating the electrical fastener.

[0016] A base station includes a base station housing with an antenna and a circuit board inside, and a junction box. The junction box is fixedly connected to the outside of the base station housing, and the electrical connectors and the antenna are electrically connected to the circuit board.

[0030] 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 core concept of the present utility model and the following embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1, a protective cover, such as Figure 3 and Figure 4 As shown, the protective cover 2 is provided with a hinge structure for connecting the electrical fastener 1. The protective cover 2 is also provided with at least one of the following: an elastic snap-fit ​​structure, a screw structure, and a plug-in structure. The elastic snap-fit ​​structure, screw structure, and plug-in structure are used to lock the connection with the electrical fastener 1.

[0032] Specifically, in this embodiment, the electrical fastener 1 is used to fix the electrical connector. The electrical fastener 1 can be a box or a component connected to the box. The protective cover 2 is made of a flexible plastic commonly used in junction boxes, such as PVC or ABS. The rear end of the protective cover 2 is hinged to the electrical fastener 1, and the front end of the protective cover 2 is locked to the electrical fastener 1.

[0033] Specifically, such as Figure 1 , Figure 2 and Figure 5As shown, threaded holes can be provided on both sides of the protective cover 2, and a through hole is provided at the rear end of the electrical fastener 1. A connecting shaft passes through the through hole on the side of the electrical fastener 1 and connects to the threaded hole. In other embodiments, the electrical fastener 1 includes a surrounding plate 1-1, and a bracket 1-3 is connected to the surrounding plate 1-1 at the rear end of the electrical fastener 1. The bracket 1-3 includes two opposing side plates, and through holes are provided on the two opposing side plates. A connecting shaft passes through the through hole on the bracket 1-3 and connects to the threaded hole, so that the rear end of the protective cover 2 can be reliably connected to the electrical fastener 1. In other embodiments, through holes are provided on both sides of the protective cover 2, and a threaded hole is provided at the rear end of the electrical fastener 1. A connecting shaft passes through the threaded hole on the side of the electrical fastener 1 and connects to the through hole. In other embodiments, the electrical fastener 1 includes a surrounding plate 1-1. A bracket 1-3 is connected to the rear end of the surrounding plate 1-1 of the electrical fastener 1. The bracket 1-3 includes two opposing side plates with threaded holes. A connecting shaft passes through the threaded holes on the bracket 1-3 and connects to the through holes, so that the rear end of the protective cover 2 can be reliably connected to the electrical fastener 1. In this embodiment, the connecting shaft can be a long screw. In other embodiments, protrusions or convex shafts can be directly provided on both sides of the rear end of the protective cover 2. Matching through holes are provided on both sides of the rear end of the electrical fastener 1. Inserting the protrusions or convex shafts into the through holes achieves a rotatable connection between the protective cover 2 and the electrical fastener 1. In other embodiments, protrusions or convex shafts can be directly provided on both sides of the rear end of the electrical fastener 1. Matching through holes are provided on both sides of the rear end of the protective cover 2. Inserting the protrusions or convex shafts into the through holes achieves a rotatable connection between the protective cover 2 and the electrical fastener 1.

[0034] like Figure 1 As shown, the protective cover 2 has a cable outlet 2-1 at its front end. The protective cover 2 has elastic locking structures on both sides near the front end, including limiting buckles. When the protective cover 2 rotates to cover the electrical fastener 1, the limiting buckles engage with the bottom surface of the electrical fastener 1. Preferably, the limiting buckles are connected to the side of the protective cover 2 and are a certain distance from the bottom surface of the protective cover 2. When the limiting buckles engage with the bottom surface of the electrical fastener 1, the bottom surface of the protective cover 2 protrudes beyond the bottom surface of the electrical fastener 1, thereby ensuring better protection for the cables and other electrical components on the electrical fastener 1. In other embodiments, the limiting buckles can also engage with the side of the electrical fastener 1. A groove matching the limiting buckle is provided on the side of the electrical fastener 1. When the protective cover 2 rotates to cover the electrical fastener 1, the limiting buckle engages with the groove on the side of the electrical fastener 1. By prying the side of the protective cover 2 outwards, the limiting buckle disengages from the groove, and the protective cover 2 can be flipped.

[0035] Preferably, such as Figure 2 and Figure 8As shown, the protective cover 2 can be provided with a flexible snap-fit ​​structure on one side near the front end, and a screw-fit or plug-in structure on the other side. In other embodiments, such as Figure 7 As shown, screw-in or plug-in structures can also be provided on both sides of the protective cover 2 near the front end, through which screws or bolts can be passed to connect the electrical fastener 1. In summary, the two sides of the protective cover 2 near the front end can be configured with any combination of the three structures.

[0036] Furthermore, the outer contour of the protective cover 2 should match the outer contour of the electrical fastener 1, and the outer contour of the protective cover 2 should fit over the outer edge of the outer contour of the electrical fastener 1, forming a cavity between the protective cover 2 and the electrical fastener 1 to accommodate the connecting cables and other electrical components. Flexible snap-fit ​​structures, screw-fit structures, and plug-in structures can all be used to restrict the rotation of the protective cover 2 and lock it securely to the surface of the electrical fastener 1, thereby protecting the cables and other electrical components within the cavity from damage caused by outdoor environments such as sun, rain, and bird droppings, thus ensuring the stability of the optical and electrical performance of the adapter box.

[0037] Example 2, based on Example 1, provides a protective cover, such as... Figure 1 and Figure 2 As shown, the protective cover 2 is provided with limiting structures 2-2 on both sides. The limiting structures 2-2 include a first stop surface 2-2-1 for cooperating with the electrical fastener 1 in the first direction and a second stop surface 2-2-2 for cooperating with the electrical fastener 1 in the second direction.

[0038] Specifically, such as Figure 1 As shown, two limiting structures 2-2 are symmetrically arranged on both sides of the protective cover 2. Each limiting structure 2-2 includes a first stop plate and a second stop plate. The sides of the first and second stop plates closest to the electrical fastener 1 are respectively a first stop surface 2-2-1 and a second stop surface 2-2-2, which are perpendicularly connected. When the protective cover 2 is locked to the electrical fastener 1, the first stop surface 2-2-1 is used to stop on the top of the electrical fastener 1, and the second stop surface 2-2-2 is used to stop on the side of the electrical fastener 1. Furthermore, the limiting structures 2-2 can improve the strength of the protective cover 2 and prevent it from shifting, thus ensuring that the protective cover 2 provides better protection for the cables and other electrical components on the electrical fastener 1. In other embodiments, the first stop surface 2-2-1 and the second stop surface 2-2-2 may not be perpendicular, as long as the first stop surface 2-2-1 can abut against the top of the electrical fastener 1 and the second stop surface 2-2-2 can abut against the side of the electrical fastener 1.

[0039] like Figure 1As shown, the protective cover 2 has elastic snap-fit ​​structures on both sides near the front end. Specifically, both sides of the front end of the protective cover 2 are locked by limiting structures 2-2 and buckles 2-3. Figure 2 As shown, the protective cover 2 has a flexible snap-fit ​​structure on one side near the front end, and a screw-fit or plug-in structure on the other side. One side of the front end of the protective cover 2 is locked by the limiting structure 2-2 and the buckle 2-3. The other side of the front end uses a single screw, bolt or pin to further lock the protective cover 2 and the electrical fastener 1. On the basis of the hinge and snap-fit, the use of a single screw, bolt or pin to connect slightly increases the workload, but it can bring a better locking effect.

[0040] Example 3, based on Example 2, a protective cover, such as... Figure 1 , Figure 2 , Figure 6 and Figure 8 As shown, the elastic snap-fit ​​structure includes a snap-fit ​​2-3 for engaging with a third-party stop on the electrical fastener 1. The snap-fit ​​2-3 is connected to the second stop surface 2-2-2. Specifically, the snap-fit ​​2-3 is connected to the bottom of the second stop surface 2-2-2. When the front sides of the protective cover 2 are configured with elastic snap-fit ​​structures, the protective cover 2 rotates through the hinge structure. When the first stop surface 2-2-1 stops at the top of the electrical fastener 1, the second stop surface 2-2-2 stops at the side of the electrical fastener 1, and the snap-fit ​​2-3 snaps onto the bottom of the electrical fastener 1. The limiting structure 2-2 and the snap-fit ​​2-3 work together to lock the protective cover 2 onto the surface of the electrical fastener 1. At least one snap-fit ​​2-3 is provided, and the snap-fit ​​2-3 can be provided on one side or on both sides of the protective cover 2.

[0041] Preferably, such as Figure 1 and Figure 6 As shown, the two latches 2-3 are symmetrically arranged on both sides of the bottom of the protective cover 2, which helps to improve the reliability of locking and facilitates the easy opening and closing of the protective cover 2. When it is necessary to open the protective cover 2, the limiting structure 2-2 at the front end of the protective cover 2 is pried outward, and the latches 2-3 will disengage from the bottom stop of the electrical fastener 1, allowing the protective cover 2 to be flipped upward. At this time, the hinge structure at the rear end of the protective cover 2 acts as a pivot, allowing it to be easily opened without tools, which facilitates the maintenance and repair of cables and other electrical components on the electrical fastener 1.

[0042] Example 4, based on Example 2, provides a protective cover, wherein the screw connection structure includes a matching threaded hole and a fastener 4 for engaging with a third-party stop of the electrical fastener 1, and the threaded hole is located on the second stop surface 2-2-2.

[0043] Specifically, when the front sides of the protective cover 2 are set with screw connections, the protective cover 2 can rotate through the hinge structure. When the first stop surface 2-2-1 stops at the top of the electrical fastener 1, the second stop surface 2-2-2 stops at the side of the electrical fastener 1, and the fastener 4 on the second stop surface 2-2-2 passes through the threaded hole and stops at the bottom surface of the electrical fastener 1.

[0044] Example 5, based on Example 2, a protective cover, such as... Figure 2 , Figure 7 and Figure 8 As shown, the screw connection structure includes a matching threaded hole and a fastener 4 for connecting with the hole of the electrical fastener 1. The threaded hole is provided on the first stop surface 2-2-1 and / or the second stop surface 2-2-2.

[0045] In this embodiment, as Figure 7 and Figure 8 As shown, the electrical fastener 1 is provided with an auxiliary bracket with holes. The protective cover 2 rotates through the hinge structure. When the first stop surface 2-2-1 stops at the top of the electrical fastener 1, the second stop surface 2-2-2 stops at the side of the electrical fastener 1. The fastener 4 on the second stop surface 2-2-2 passes through the threaded hole and connects to the hole of the auxiliary bracket. The fastener 4 can be a screw or a bolt.

[0046] In other embodiments, the fasteners 4 on the first stop surface 2-2-1 and / or the second stop surface 2-2-2 can also be connected to the top surface and / or side surface of the electrical fastener 1 after passing through the threaded holes. Correspondingly, the electrical fastener 1 should have matching threaded holes or through holes at corresponding positions on the top surface and / or side surface.

[0047] Example 6, based on Example 2, a protective cover, such as... Figure 2 , Figure 7 and Figure 8 As shown, the plug-in structure includes a matching through hole 1 and a fastener 4 for connecting with the hole of the electrical fastener 1. The through hole 1 is provided on the first stop surface 2-2-1 and / or the second stop surface 2-2-2.

[0048] Specifically, such as Figure 7As shown, when the front sides of the protective cover 2 are configured with plug-in structures, the protective cover 2 rotates through the hinge structure. When the first stop surface 2-2-1 stops at the top of the electrical fastener 1, the second stop surface 2-2-2 stops at the side of the electrical fastener 1. The fasteners 4 on the first stop surface 2-2-1 and / or the second stop surface 2-2-2 pass through the through hole and are connected to the top or side of the electrical fastener 1, or to the auxiliary bracket of the electrical fastener 1. Correspondingly, the electrical fastener 1 should have matching threaded holes at corresponding positions on the top and / or side, or at corresponding positions on the auxiliary bracket. The fasteners 4 can be screws or bolts.

[0049] Example 7, a protective cover, based on any one of Examples 1-6, wherein the hinge structure includes a matching through hole 2 and a rotating shaft 3 for connecting with the hole of the electrical fastener 1.

[0050] Specifically, the second through hole is provided on both sides of the protective cover 2, and the two sides of the electrical fastener 1 are provided with threaded holes. The rotating shaft 3 passes through the threaded holes on the side of the electrical fastener 1 and connects to the second through hole.

[0051] In other embodiments, the electrical fastener 1 includes a surrounding plate 1-1. The rear end of the surrounding plate 1-1 of the electrical fastener 1 is connected to a bracket 1-3. The bracket 1-3 includes two opposing side plates with threaded holes. The rotating shaft 3 passes through the threaded holes on the bracket 1-3 and connects to the through hole so that the rear end of the protective cover 2 can be reliably connected to the bracket 1-3.

[0052] Furthermore, the distance from the second through hole to the end of the protective cover 2 is less than the distance from the through hole to the top of the bracket 1-3. When the protective cover 2 rotates around the rotating shaft 3, interference between the end of the protective cover 2 and the electrical fastener 1 is avoided, allowing the protective cover 2 to rotate freely when opened.

[0053] Example 8, a protective cover, based on Example 7, such as... Figure 1 , Figure 2 and Figure 5 As shown, the protective cover 2 is provided with mounting ears 2-4, and the hinge structure is provided on the mounting ears 2-4. Specifically, the rear end of the protective cover 2 is provided with mounting ears 2-4, and the mounting ears 2-3 of the protective cover 2 are provided with a through hole and a rotating shaft 3. Correspondingly, a threaded hole is provided on the electrical fastener 1. The rotating shaft 3 passes through the through hole on the mounting ear 2-3 to connect to the electrical fastener 1.

[0054] In implementation, a mounting ear 2-3 is provided on each side of the rear end of the protective cover 2. Each mounting ear 2-3 is provided with a matching through hole 2 and a rotating shaft 3. The two side plates of the bracket 1-3 are located between the two mounting ears 2-3. The two opposite side plates are provided with threaded holes in opposite positions. The rotating shaft 3 passes through the threaded holes and connects to the through hole 2.

[0055] In other embodiments, such as Figure 1 , Figure 2 and Figure 5 As shown, the protective cover 2 has a pair of mounting ears 2-3 on each side of its rear end. Each pair of mounting ears 2-3 has a through hole and a threaded hole. The bracket 1-3 has through holes on its two sides. The rotating shaft 3 passes through the through holes on the bracket 1-3 and is tightened with the through holes and threaded holes on the mounting ears 2-3, thus rotatably connecting the protective cover 2 to the bracket 1-3. Alternatively, each pair of mounting ears 2-3 may have a through hole, and the bracket 1-3 may have threaded holes on its two sides. The rotating shaft 3 passes through the outer through hole, the threaded hole, and the inner through hole, thus rotatably connecting the protective cover 2 to the bracket 1-3. Preferably, the rotating shaft 3 is a screw.

[0056] Example 9, an adapter box, such as Figures 3 to 8 As shown, it includes an electrical fastener 1 and a protective cover 2 as described in any one of embodiments 1-8. The protective cover 2 is rotatably connected to the electrical fastener 1 through the hinge structure, and is locked to the electrical fastener 1 through at least one of the elastic snap-fit ​​structure, screw structure, and plug-in structure.

The bracket 1-3 includes two opposing side plates, and through holes are provided on the two opposing side plates. The rotating shaft 3 passes through the through hole on the bracket 1-3 and connects to the threaded hole. In other embodiments, a mounting ear 2-3 is provided on each side of the rear end of the protective cover 2, and each mounting ear 2-3 has a matching threaded hole. The rotating shaft 3 passes through the through hole on the side of the electrical fastener 1 or through the through hole on the bracket 1-3 and connects to the threaded hole. Preferably, the rotating shaft 3 is a screw.

[0058] In other embodiments, such as Figure 7As shown, the protective cover 2 has a pair of mounting ears 2-3 on each side of its rear end, with each pair of mounting ears 2-3 spaced apart. The bottom of the bracket 1-3 is flush with the bottom of the electrical fastener 1, and the two side plates of the bracket 1-3 are respectively inserted into the gaps between the two pairs of mounting ears 2-3. Each pair of mounting ears 2-3 has a threaded hole on the inner side, and the bracket 1-3 has through holes on its two sides. A connecting shaft passes through the through holes and is tightened into the threaded holes on the mounting ears 2-3, thus rotatably connecting the protective cover 2 to the bracket 1-3; or each pair of mounting ears 2-3 has a threaded hole, and the bracket 1-3 has through holes on its two sides. A connecting shaft passes through the outer threaded hole, the through hole, and the inner threaded hole, thus rotatably connecting the protective cover 2 to the bracket 1-3. Preferably, the connecting shaft is a screw.

[0059] In other embodiments, the protective cover 2 has two through holes on its two sides, and the electrical fastener 1 has threaded holes on its two sides. The rotating shaft 3 passes through the threaded holes on the side of the electrical fastener 1 and connects to the through holes. In other embodiments, the electrical fastener 1 includes a surrounding plate 1-1. The rear end of the surrounding plate 1-1 of the electrical fastener 1 is connected to a bracket 1-3. The bracket 1-3 includes two opposing side plates, each with a threaded hole. The rotating shaft 3 passes through the threaded hole on the bracket 1-3 and connects to the through hole, so that the rear end of the protective cover 2 can be reliably connected to the bracket 1-3. In other embodiments, the protective cover 2 has a mounting ear 2-3 on each side of its rear end. Each mounting ear 2-3 has a matching through hole and a rotating shaft 3. The two side plates of the bracket 1-3 are located between the two mounting ears 2-3. The two opposing side plates have threaded holes in opposite positions. The rotating shaft 3 passes through the threaded holes and connects to the through holes. In other embodiments, a pair of mounting ears 2-3 are provided on each side of the rear end of the protective cover 2, with each pair of mounting ears 2-3 spaced apart. The bottom of the bracket 1-3 is flush with the bottom of the electrical fastener 1, and the two side plates of the bracket 1-3 are respectively inserted into the gaps between the two pairs of mounting ears 2-3. Each pair of mounting ears 2-3 is provided with a through hole and a threaded hole. The two sides of the bracket 1-3 are provided with through holes, and the rotating shaft 3 passes through the through holes on the bracket 1-3 and is tightened with the through holes and threaded holes on the mounting ears 2-3 to rotatably connect the protective cover 2 to the bracket 1-3; or each pair of mounting ears 2-3 is provided with a through hole, and the two sides of the bracket 1-3 are provided with threaded holes. The rotating shaft 3 passes through the outer through hole and the threaded hole and is tightened with the inner through hole to rotatably connect the protective cover 2 to the bracket 1-3. Preferably, the rotating shaft 3 is a screw.

[0060] Furthermore, such as Figure 1 and Figure 2As shown, the surface of the enclosure 1-1 is provided with reinforcing ribs 1-2. By pressing down on the protective cover 2, the protective cover 2 is pressurized to fit the enclosure 1-1, improving the sealing performance and locking reliability of the protective cover 2 after it is fastened to the electrical fastener 1. In other embodiments, the reinforcing ribs 1-2 may also be provided on the two inner sides of the protective cover 2.

[0061] Furthermore, such as Figure 1 , Figure 2 , Figures 6 to 8 As shown, the front end of the protective cover 2 is provided with a cable outlet 2-1. The front end of the protective cover 2 is also provided with at least one of the following: an elastic snap-fit ​​structure, a screw connection structure, and a plug-in structure, which are fastened and locked to the front end of the electrical fastener 1. The elastic snap-fit ​​structure, screw connection structure, and plug-in structure can all be used to restrict the rotation of the protective cover 2 and lock the protective cover 2 to the surface of the electrical fastener 1.

[0062] Furthermore, such as Figure 7 and Figure 8 As shown, when the protective cover 2 is locked to the electrical fastener 1 via the screw or plug-in structure, using a fastener 4 on one side of the protective cover 2 to lock the protective cover 2 and the enclosure 1-1, or using a fastener 4 on each side of the protective cover 2 to lock the protective cover 2 and the enclosure 1-1, helps improve the reliability of the locking and simplifies the opening and closing of the adapter box. Preferably, the fastener 4 is a screw or a pin. Based on the hinge connection, one or two screws or one or two pins are used to lock the protective cover 2 and the electrical fastener 1. Compared to the traditional method of using screws to connect the protective cover and the electrical fastener, the number of fasteners 4 is reduced, reducing the workload of workers opening and closing the adapter box while ensuring connection reliability. Compared to the method of using limit clips, rotary connectors, and locking devices, the connection of one or two screws or the insertion of one or two pins will slightly increase the workload of maintenance, but the reliability of locking is greatly improved.

[0063] Example 10: A base station includes a base station housing with an internal antenna and circuit board, and the adapter box described in Example 9. The adapter box is fixedly connected to the outside of the base station housing, and the electrical connectors and antenna are electrically connected to the circuit board.

[0064] Specifically, the adapter box can be connected to the base station via a fixed bracket or directly via the rear end of the electrical fastener 1.
