Description

Technical Field

[0001] This utility model relates to the field of live broadcast vehicle cable technology, and more specifically, to a cable joint sealing and protection device. Background Technology

[0002] As the core carrier of outdoor mobile live streaming, the live streaming vehicle needs to be deployed quickly in various scenarios such as concerts, sports events, and breaking news. Its on-board equipment (such as high-definition cameras, audio mixing consoles, and signal transmitters) relies on a large number of cables to achieve signal transmission and equipment coordination. Such operating scenarios have significant special characteristics: First, the operation is time-sensitive. Before the live broadcast, multiple sets of cables need to be plugged and unplugged and debugged in a short period of time. During the live broadcast, the connectors may need to be replaced temporarily due to camera switching or equipment adjustment. Second, the environment is complex and changeable. It often faces outdoor wind, rain, and dust. Moreover, the movement of the vehicle or the movement of people can easily cause the cables to be pulled and vibrated by external forces. Since the various cables are interconnected, protective devices are usually equipped on the connectors to protect the connection points and avoid the influence of the external environment.

[0003] Regarding the aforementioned technologies, existing protective devices come in various forms. One type is a protective cover directly fixed to the outside of the connector with bolts, and the other is a plug-in type protective device that covers the outside of the connector. Although these are non-fixed connections and can be easily plugged and unplugged along with the connector, the live broadcast vehicle connector requires a relatively loose plugging and unplugging force to improve efficiency during rapid plugging and unplugging adjustments. During long-term connection, a greater separation force is required to prevent vibration and detachment. In some scenarios, locking fixation is also necessary, but existing protective devices cannot meet these requirements. Firstly, although bolt-fixed protection can lock the connector, it requires tools for disassembly, lacks the function of adjusting the plugging and unplugging force, and cannot adapt to rapid debugging scenarios, thus delaying deployment. Secondly, although plug-in protection supports rapid plugging and unplugging, it only provides a single fixed resistance. If the resistance is too loose, it is easy to detach during long-term connection, causing wind, rain, and dust to seep in and cause signal interruption. If the resistance is too tight, it increases the difficulty of rapid plugging and unplugging and has no locking capability. Therefore, a cable connector sealing and protective device is proposed. Utility Model Content

[0004] To solve the above problems, this utility model provides a cable joint sealing and protection device, which adopts the following technical solution: A cable connector sealing and protection device includes a main module and a connection protection module. The main module includes two cables, with a first connector and a second connector fixedly connected to adjacent ends of the two cables, respectively. The first connector and the second connector are movably connected. The connection protection module includes a mating block connected to the outer surface of the first connector. A protective cover is fixedly connected to one side of the mating block. A sleeve block is fixedly connected to the outer surface of the second connector. The sleeve block is movably fitted onto the outer surfaces of the protective cover and the mating block. The inner wall of the sleeve block has multiple mating grooves arranged in a ring at equal intervals. The interior of the mating block has multiple snap-fit ​​components arranged in a ring at equal intervals. The multiple snap-fit ​​components are respectively connected to the multiple mating grooves. A push-up component is arranged between the interior of the protective cover and the multiple snap-fit ​​components. The outer surface of the protective cover has a resistance groove.

[0005] Furthermore, the snap-fit ​​assembly includes a displacement groove formed on the outer surface of the mating block, a movable block and a snap-fit ​​block are movably connected inside the displacement groove, one end of the snap-fit ​​block is provided with a double-sided slope groove, one end of the snap-fit ​​block is movably connected inside one of the mating grooves, and a resistance spring is fixedly connected between the movable block and the snap-fit ​​block.

[0006] Furthermore, the snap-fit ​​assembly also includes a connecting groove formed on one side of the mating block, the connecting groove communicating with the displacement groove, and the movable block extending to one side of the mating block through the connecting groove.

[0007] Furthermore, the booster assembly includes an adjusting ring movably connected inside the protective cover. An adjusting screw is rotatably connected between one side of the docking block and the protective cover. The outer surface of the adjusting screw is threadedly connected to the adjusting ring. One end of the adjusting screw extends to the outside of the protective cover. A plurality of connecting rods are hinged to one side of the adjusting ring. One end of one of the connecting rods is hinged to the outer surface of the movable block. A flipping plate is movably connected to one end of the adjusting screw. A storage base is fixedly connected to one side of the protective cover. The flipping plate is movably connected inside the storage base.

[0008] Furthermore, the booster assembly also includes a blocking groove formed between the docking block and the outer surface of the protective cover. The adjusting ring extends to the outside of the protective cover through the blocking groove. The resistance groove is located on one side of the blocking groove. Two blocking plates are fixedly connected to the outer surface of the adjusting ring, and both blocking plates are slidably connected inside the blocking groove.

[0009] Furthermore, the connection protection module also includes a sealing ring fixedly connected to the other side of the docking block, and an inner concave retaining ring fixedly connected to the inner wall of the fitting block, with the sealing ring movably connected inside the inner concave retaining ring.

[0010] In summary, this utility model has the following beneficial technical effects: (1) This utility model achieves three usage states by setting up a docking block, a set block, a snap-fit ​​component, a docking groove, and a booster component. When docking, the snap-fit ​​component snaps into the docking groove, which can be quickly inserted and removed to meet the debugging requirements. Rotating the booster component can push the snap-fit ​​component to increase the separation resistance and adapt to long-term docking to prevent loosening. When the snap-fit ​​component is retracted to the extreme, it can lock the connection between the docking block and the set block to meet the fixation requirements, adapt to different scenarios of the live broadcast vehicle, and improve the operational flexibility.

[0011] (2) This utility model optimizes adjustment and protection by setting up a storage base, a flip plate, a blocking groove, a blocking plate and a resistance groove. After the flip plate is taken out of the storage base, it can rotate to drive the booster component to adjust the resistance. When it is not in use, it can be stored. By observing the position of the adjustment ring and the resistance groove, the resistance can be judged. When the adjustment ring moves, the blocking plate slides in the blocking groove, blocking the blocking groove to prevent dust from entering the protective cover and ensuring the stability of the internal components.

[0012] (3) This utility model enhances the sealing and protection effect by setting the concave retaining ring and the sealing ring. When the first connector and the second connector are connected, the sealing ring is inserted into the concave retaining ring to fill the gap between the connecting block and the kit block, reduce the penetration of outdoor wind, rain and dust into the connector, avoid signal interruption or component corrosion, adapt to the complex outdoor environment of the live broadcast vehicle, and improve the reliability of connector protection.

[0018] The following is in conjunction with the appendix Figures 1-5 The present invention will be described in further detail below.

[0019] Please see Figures 1-5A cable connector sealing and protection device includes a main module 100 and a connection protection module 200. The main module 100 includes two cables 110, with a first connector 120 and a second connector 130 fixedly connected to adjacent ends of the two cables 110, respectively. The first connector 120 and the second connector 130 are movably connected. The connection protection module 200 includes a mating block 210 connected to the outer surface of the first connector 120, with a protective cover 230 fixedly connected to one side of the mating block 210. The outer surface of the second connector 130... A fixed connection is provided with a sleeve block 220, which is movably fitted onto the outer surface of the protective cover 230 and the docking block 210. The inner wall of the sleeve block 220 is provided with multiple docking grooves 250 at equal intervals in a ring shape. The interior of the docking block 210 is provided with multiple snap-fit ​​components 240 at equal intervals in a ring shape. The multiple snap-fit ​​components 240 are respectively connected to the multiple docking grooves 250. A booster component 260 is provided between the interior of the protective cover 230 and the multiple snap-fit ​​components 240. The outer surface of the protective cover 230 is provided with a resistance groove 270.

[0020] During use, the operator mates the first connector 120 with the second connector 130. During mating, the snap-fit ​​component 240 retracts. When the snap-fit ​​component 240 overlaps with the mating groove 250, it enters the groove, thus completing the connection between the mounting block 220, the mating block 210, and the protective cover 230. Simultaneously, the second connector 130 connects to the first connector 120. Pulling it outwards separates the second connector 130 from the first connector 120, and the mounting block 220 from the mating block 210. In this state, frequent insertion and removal can be performed for quick adjustments. When the first connector 120 and the second connector 130 are mated, the multiple snap-fit ​​components 240 can be pushed by rotating the booster component 260. The multiple snap-fit ​​components 240 will increase the resistance during separation, thus facilitating long-term mating and preventing loosening during use. When the snap-fit ​​component 240 retracts to its maximum, it can lock the connection between the mating block 210 and the mounting block 220, providing a locking function. Users can choose to operate according to their preference, making it more convenient for them to use.

[0021] The snap-fit ​​assembly 240 includes a displacement groove 241 formed on the outer surface of the mating block 210. A movable block 242 and a snap-fit ​​block 244 are movably connected inside the displacement groove 241. One end of the snap-fit ​​block 244 is provided with a double-sided slope groove. One end of the snap-fit ​​block 244 is movably connected inside one of the mating grooves 250. A resistance spring 243 is fixedly connected between the movable block 242 and the snap-fit ​​block 244. The snap-fit ​​assembly 240 also includes a connecting groove formed on one side of the mating block 210. The connecting groove communicates with the displacement groove 241. The movable block 242 extends to one side of the mating block 210 through the connecting groove.

[0022] When the first connector 120 and the second connector 130 are connected, the locking block 244 will be squeezed into the displacement groove 241 by the inner wall of the sleeve block 220. At this time, the resistance spring 243 is pressed and contracted. When the locking block 244 overlaps with the docking groove 250, the resistance spring 243 springs open and drives the locking block 244 to lock into the docking groove 250, thereby completing the connection between the sleeve block 220, the docking block 210 and the protective cover 230. The first connector 120 is also connected to the second connector 130. Pulling the two cables 110 outward can separate the second connector 130 from the first connector 120, separate the sleeve block 220 from the docking block 210, and remove the locking block 244 from the docking groove 250. In this state, frequent plugging and unplugging can be performed for quick adjustment. The resistance spring 243 is made of carbon steel and can be replaced periodically according to wear and tear.

[0023] The booster assembly 260 includes an adjusting ring 262 movably connected inside the protective cover 230. An adjusting screw 261 is rotatably connected between one side of the docking block 210 and the protective cover 230. The outer surface of the adjusting screw 261 is threadedly connected to the adjusting ring 262. One end of the adjusting screw 261 extends to the outside of the protective cover 230. Multiple connecting rods 263 are hinged to one side of the adjusting ring 262. One end of one connecting rod 263 is hinged to the outer surface of the movable block 242. A flipping plate 26 is movably connected to one end of the adjusting screw 261. 4. A storage base 265 is fixedly connected to one side of the protective cover 230. The flipping plate 264 is movably connected inside the storage base 265. The booster assembly 260 also includes a blocking groove 266 formed between the docking block 210 and the outer surface of the protective cover 230. The adjusting ring 262 extends to the outside of the protective cover 230 through the blocking groove 266. The resistance groove 270 is located on one side of the blocking groove 266. Two blocking plates 267 are fixedly connected to the outer surface of the adjusting ring 262. Both blocking plates 267 are slidably connected inside the blocking groove 266.

[0024] When the first connector 120 and the second connector 130 are connected, the flip plate 264 can be flipped to remove them from the storage base 265. Then, the flip plate 264 is rotated, which will drive the adjusting screw 261 to rotate. The adjusting screw 261 will drive the adjusting ring 262 to move. During the movement of the adjusting ring 262, it will be pushed by the connecting rod 263. The adjusting ring 262 will compress the movable block 242, thereby increasing the pressure applied to the locking block 244 by the resistance spring 243. This increases the resistance when pulling the locking block 244 out of the docking groove 250, which is convenient for long-term docking and prevents loosening during use. When the resistance spring 243 is fully contracted, the locking block 244 will not be able to move back, thus locking the locking block 244 inside the docking groove 250. This locks the connection between the docking block 210 and the sleeve block 220, giving it a locking function.

[0025] The connection protection module 200 also includes a sealing ring 280 fixedly connected to the other side of the docking block 210, and an inner concave retaining ring 290 fixedly connected to the inner wall of the sleeve block 220, with the sealing ring 280 movably connected inside the inner concave retaining ring 290.

[0026] When the first connector 120 and the second connector 130 are mated, the sealing ring 280 is engaged with the concave retaining ring 290, thereby improving the sealing performance when the mating block 210 and the sleeve block 220 are connected, and further enhancing the protective effect.

[0027] The implementation principle of this utility model embodiment is as follows: During use, the operator connects the first connector 120 and the second connector 130. During connection, the locking block 244 will be squeezed into the displacement groove 241 by the inner wall of the sleeve block 220. At this time, the resistance spring 243 is pressed and contracted. When the locking block 244 overlaps with the docking groove 250, the resistance spring 243 springs open, causing the locking block 244 to engage with the docking groove 250, thereby completing the connection between the sleeve block 220, the docking block 210, and the protective cover 230. The first connector 120 is also connected to the second connector 130. Pulling the two cables 110 outward will allow the second connector 130 to engage. When connector 130 separates from first connector 120, sleeve block 220 separates from docking block 210, and locking block 244 retracts from docking slot 250, frequent insertion and removal and rapid adjustment can be performed. When first connector 120 and second connector 130 are docked, flip plate 264 can be flipped to remove them from storage base 265. Then, rotating flip plate 264 will drive adjusting screw 261 to rotate. Adjusting screw 261 will drive adjusting ring 262 to move. During the movement of adjusting ring 262, it will push adjusting ring 262 through connecting rod 263. This will compress the movable block 242, thereby increasing the pressure exerted by the resistance spring 243 on the locking block 244. This increases the resistance when pulling the locking block 244 out of the docking groove 250, facilitating long-term docking and preventing loosening during use. When the resistance spring 243 is fully compressed, the locking block 244 will be unable to retract, thus locking the locking block 244 inside the docking groove 250. This locks the connection between the docking block 210 and the fitting block 220, providing a locking function. Users can operate according to their preferences, making it more convenient to use. During the movement of the adjusting ring 262... During the process, the adjusting ring 262 will move inside the blocking groove 266. By observing the positional relationship between the adjusting ring 262 and the resistance groove 270, the magnitude of the adjusted resistance can be checked. At the same time, when the adjusting ring 262 moves, the blocking plate 267 will slide inside the blocking groove 266, thereby blocking the blocking groove 266 on the outer surface of the protective cover 230 to prevent dust from entering the interior of the protective cover 230. When the first connector 120 and the second connector 130 are connected, the sealing ring 280 is engaged with the concave retaining ring 290, thereby improving the sealing performance when the connecting block 210 and the fitting block 220 are connected, further enhancing the protective effect.

[0028] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
