Description

Technical Field

[0001] This utility model relates to the field of cable joint protection, and in particular to a cable joint protection device for broadcast television coverage. Background Technology

[0002] In broadcast television coverage systems, cables serve as a key medium for signal transmission. Their stability and reliability directly determine the transmission quality and coverage of broadcast television signals. Broadcast television signals must be accurately transmitted to various receiving terminals, such as television and radio receiving equipment, through cables to ensure that users can receive program content stably and clearly.

[0003] Existing cable connections for broadcast television coverage typically rely on manual insertion of cable connectors into equipment ports. However, when the temperature at the cable connector rises due to excessive current, poor contact, or other reasons, current equipment cannot detect this in time and take appropriate protective measures. Excessive temperature accelerates the aging and damage of cable insulation materials, reduces insulation performance, and increases the risk of leakage and short circuits. This can not only easily damage cables and equipment but may also cause serious safety accidents such as fires, affecting the safety of use.

[0004] Therefore, it is necessary to design a cable joint protection device for broadcast television coverage that can automatically move the connector to connect the cable and automatically disconnect the cable when a high temperature is detected, thereby protecting the cable, preventing fire and fault spread, and improving the safety of use. Utility Model Content

[0005] To overcome the shortcomings of current equipment that cannot detect and take corresponding protective measures in a timely manner, excessively high temperatures can accelerate the aging and damage of cable insulation materials, reduce insulation performance, and increase the risk of leakage and short circuits. This not only easily damages cables and equipment but may also cause serious safety accidents such as fires, affecting the safety of use. This utility model provides a cable joint protection device for broadcast television coverage that can automatically move the joint to connect the cable and automatically disconnect the cable joint when high temperature is detected, thus protecting the cable, preventing fire and fault spread, and improving the safety of use.

[0006] The technical solution is as follows: A cable joint protection device for broadcast television coverage includes a cable, a spring protection tube, a joint, a locking frame, a connecting frame, a movable frame, a fixed locking frame, a protective component, and an anti-electric shock component. The movable frame is slidably connected to the left side of the connecting frame. Fixed locking frames are connected to both the left and right sides of the movable frame. A spring protection tube is locked between the fixed locking frames. A cable is placed on the spring protection tube. A joint is threadedly connected to the rear of the spring protection tube. A locking frame is connected to the front side of the joint. The locking frame is locked to the cable. The connecting frame is provided with a protective component for driving the joint to move and disconnect from the equipment when the temperature is high for protection. An anti-electric shock component is provided between the connecting frame and the movable frame for protection against electric shock.

[0007] As a preferred technical solution of this utility model, the connecting frame has two mounting holes on the left and right sides.

[0008] As a preferred technical solution of this utility model, the mobile frame is foldable.

[0009] As a preferred technical solution of this utility model, the lower part of the fixed card holder is provided with a limiting block.

[0010] As a preferred technical solution of this utility model, the drive assembly includes a motor, a lead screw, and a temperature sensor. The motor is connected to the front right part of the connecting frame. The motor and the processor are electrically connected through a control module.

[0012] The present invention has the following advantages: 1. The present invention moves the movable frame, which drives the spring protection tube and the cable to move, so that the connector moves and engages with the connector on the equipment. The temperature sensor detects the temperature. When the temperature is high, the connector moves and resets to disconnect from the connector on the equipment. Thus, the connector can automatically move and connect to achieve cable connection. At the same time, when the temperature is high, the cable connector is automatically pulled out to disconnect, protecting the cable, preventing fire and fault spread, and improving safety in use.

[0020] A cable joint protection device for broadcast television coverage, such as Figures 1-4 As shown, the device includes a cable 1, a spring protection tube 2, a connector 3, a locking frame 4, a connecting frame 5, a movable frame 9, a fixed locking frame 10, protective components, and an anti-electric shock component. The connecting frame 5 has two mounting holes on both the left and right sides for easy fixing. The movable frame 9 is slidably connected to the left side of the connecting frame 5. The movable frame 9 is folded for easy support. Fixed locking frames 10 are connected to both the left and right sides of the movable frame 9. Each fixed locking frame 10 has a limit block at the bottom for easy positioning. The spring protection tube 2 is locked between the fixed locking frames 10. The cable 1 is placed on the spring protection tube 2. The connector 3 is connected to the rear of the spring protection tube 2 by a thread. The locking frame 4 is connected to the front of the connector 3. The locking frame 4 is locked to the cable 1. The connecting frame 5 is equipped with a protective component for driving the connector 3 to move and disconnect from the equipment when the temperature is high for protection. An anti-electric shock component is provided between the connecting frame 5 and the movable frame 9 for protection against electric shock.

[0021] like Figure 1 and Figure 4As shown, the drive assembly includes a motor 7, a lead screw 8, and a temperature sensor 13. The motor 7 is connected to the front right side of the connecting frame 5. The motor 7 and the processor are electrically connected through a control module. The lead screw 8 is connected to the output shaft of the motor 7. The lead screw 8 is rotatably connected to the connecting frame 5. The lead screw 8 is connected to the moving frame 9 through a thread. The temperature sensor 13 is connected to the upper part of the connecting frame 5. The temperature sensor 13 is electrically connected to the motor 7.

[0022] like Figure 4 As shown, the anti-electric shock assembly includes a first connecting post 6, a second connecting post 11, and a grounding wire 12. The first connecting post 6 is connected to the lower side of the connecting frame 5, and the second connecting post 11 is connected to the lower side of the middle part of the fixing bracket 10. The grounding wire 12 is connected between the second connecting post 11 and the first connecting post 6.

[0023] When broadcast television coverage requires protection for cable 1 connector 3, this device can be used. The connecting bracket 5 contacts the equipment, and screws are passed through the mounting holes to fix the connecting bracket 5 to the connector 3 of the equipment. Then, cable 1 is placed on the spring protection tube 2 and engaged with the locking bracket 4. Connector 3 is then engaged with the spring protection tube 2 and rotated for installation, thus completing the installation of cable 1. Next, the spring protection tube 2 is engaged with the fixed locking bracket 10, causing the spring protection tube 2 to contact the limiting block for limiting. Then, the processor starts the motor 7 through the control module. The motor 7 drives the lead screw 8 to rotate, causing the moving bracket 9 to move along the connecting bracket 5 under the action of the thread. This moves the fixed locking bracket 10 and the grounding wire 12, which in turn moves the spring protection tube 2 and cable 1, allowing connector 3 to move and engage with connector 3 on the equipment for communication. The moving bracket 9 is folded; during use, static electricity is conducted away through the grounding wire 12 on the first connecting post 6 and the second connecting post 11, thus automatically dissipating static electricity during use. To prevent electric shock and static electricity buildup, reduce dust accumulation, and extend the service life of cable 1, a temperature sensor 13 detects the temperature at connector 3. When a high temperature is detected, motor 7 reverses its operation, causing lead screw 8 to rotate in the opposite direction. Under the action of the thread, moving frame 9 moves and resets, driving fixed bracket 10 and grounding wire 12 to move and reset, which in turn drives spring protection tube 2 and cable 1 to move and reset, causing connector 3 to move and disconnect from connector 3 on the equipment, thus protecting cable 1 connector 3. This allows for automatic movement of connector 3 to connect cable 1 while automatically disconnecting cable 1 connector 3 when a high temperature is detected, protecting cable 1, preventing fire and fault spread, and improving safety. Afterwards, maintenance personnel inspect cable 1 and equipment. If no problems are found, the above operation is repeated to connect cable 1 for continued use. If problems are found, spring protection tube 2 is removed from fixed bracket 10 and replaced, and the above operation is repeated to install and connect cable 1.
