Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a special clamping fixture for assembling set-top box antennas. Background Technology

[0002] A set-top box (STB), also known as a digital video converter, is an electronic device that connects a television to an external signal source. Its core function is to convert externally input signals into a format that the television can recognize and display. Technically, a set-top box receives signals from cable television networks, satellite networks, broadband networks, etc., and processes these signals through decoding, demodulation, and amplification. It converts digital signals into analog signals or digital signals suitable for television display, while simultaneously processing audio signals to output audio and video signals.

[0003] Currently, the assembly process of set-top box antennas generally relies on manual operation, lacking the assistance of specialized clamps. This results in insufficient stability of the connection between the antenna and the set-top box. During manual installation, the interface between the antenna and the set-top box may not be fully tightened, misaligned, or tilted, leading to loose physical connections. Even slight vibrations or movements may cause signal interruptions. Therefore, a specialized clamp for assembling set-top box antennas is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a special fixture for assembling set-top box antennas, in order to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a special fixture for assembling a set-top box antenna, including a set-top box body. An antenna connector is inserted into the back of the set-top box body. A connecting wire is fixedly connected to the side of the antenna connector away from the set-top box body. An internal threaded sleeve is fixedly connected to the back of the set-top box body. The internal threaded sleeve coincides with the axis of the antenna connector. An external threaded tube is threadedly connected to the inner wall of the internal threaded sleeve. A frame is fixedly connected to one end of the external threaded tube. The connecting wire is located inside the frame. A bidirectional lead screw is rotatably connected to the inside of the frame through a bearing. Two symmetrically arranged movable plates are threadedly connected to the outer surface of the bidirectional lead screw. Both movable plates are slidably connected to the frame. An arc-shaped clamping plate is fixedly connected to the side of each movable plate near the connecting wire. The inner walls of both arc-shaped clamping plates are in contact with the outer surface of the connecting wire.

[0007] Preferably, in any of the above embodiments, the inner wall of the arc-shaped clamping plate is fixedly connected with a plurality of linear array anti-slip strips, the anti-slip strips being made of rubber.

[0008] Preferably, in any of the above solutions, the top and bottom of the frame are provided with connecting grooves, and the two movable plates are slidably connected to the frame through the two connecting grooves.

[0009] Preferably, in any of the above solutions, the inner wall of the frame has two symmetrically arranged arc-shaped grooves, and the arc-shaped clamping plate is slidably connected to the frame through the arc-shaped grooves.

[0010] Preferably, in any of the above embodiments, a guide rod is fixedly connected to the inner wall of the frame, and both of the movable plates are slidably connected to the guide rod, wherein the guide rod is parallel to the bidirectional lead screw.

[0011] Preferably, in any of the above embodiments, a control knob is rotatably connected to the bottom of the frame via a bearing, and the top of the control knob is fixedly connected to the bottom of the bidirectional lead screw.

[0012] Preferably, the outer surface of the internal threaded sleeve is fixedly connected with a plurality of circumferentially arrayed reinforcing ribs, and the plurality of reinforcing ribs are all fixedly connected to the set-top box body.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0014] 1. Addressing the issue of insufficient connection stability during manual assembly of set-top box antennas, this clamp achieves precise fixation of the antenna connector to the set-top box body through the threaded engagement of an internal threaded sleeve and an external threaded tube. During installation, the antenna connector is inserted into the back of the set-top box body, and the external threaded tube is rotated to ensure a tight engagement with the internal threaded sleeve. This ensures that the axis of the antenna connector is aligned with the internal threaded sleeve, avoiding misalignment or tilting that can occur during manual tightening. The frame is threadedly connected to the internal threaded sleeve via the external threaded tube. Rotating the control knob drives the bidirectional lead screw, causing two moving plates to move towards each other along the guide rod, thus clamping the connecting cable with the arc-shaped clamping plate. This structure improves connection stability from two dimensions: interface tightening and cable fixation, through the rigid constraint of the threaded connection and the flexible fixation of the clamping mechanism, preventing signal interruption caused by incomplete tightening of the interface or cable movement.

[0015] 2. The anti-slip strips and arc-shaped clamping plate design of this fixture further enhance the fixing effect on the connecting cable. The inner wall of the arc-shaped clamping plate conforms to the cylindrical surface of the connecting cable, and the linear array of rubber anti-slip strips increases the friction of the contact surface, effectively preventing the connecting cable from slipping or twisting when subjected to external force. The guide rod and the bidirectional lead screw are set in parallel, providing a stable sliding guide for the moving plate, ensuring that the two arc-shaped clamping plates move synchronously and apply clamping force evenly, avoiding damage to the cable sheath due to uneven force. In addition, the reinforcing ribs enhance the connection strength between the internal threaded sleeve and the set-top box body, preventing deformation of the threaded connection due to long-term stress, thereby ensuring the reliability of the entire fixture system. This allows the connection between the antenna connector and the set-top box body to withstand both physical vibration and accidental pulling during daily use, significantly improving the stability and service life of the set-top box antenna after assembly.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following.

[0023] like Figures 1 to 5As shown, a special fixture for assembling a set-top box antenna includes a set-top box body 1. An antenna connector 2 is inserted into the back of the set-top box body 1. A connecting line 3 is fixedly connected to the side of the antenna connector 2 away from the set-top box body 1. An internal threaded sleeve 4 is fixedly connected to the back of the set-top box body 1. The internal threaded sleeve 4 coincides with the axis of the antenna connector 2. An external threaded tube 5 is threadedly connected to the inner wall of the internal threaded sleeve 4. A frame 6 is fixedly connected to one end of the external threaded tube 5. The connecting line 3 is located inside the frame 6. A bidirectional lead screw 7 is rotatably connected to the inside of the frame 6 through a bearing. Two symmetrically arranged movable plates 8 are threadedly connected to the outer surface of the bidirectional lead screw 7. Both movable plates 8 are slidably connected to the frame 6. An arc-shaped clamping plate 9 is fixedly connected to the side of each movable plate 8 near the connecting line 3. The inner walls of the two arc-shaped clamping plates 9 are in contact with the outer surface of the connecting line 3.

[0024] As an optional technical solution of this utility model, the inner wall of the arc-shaped clamping plate 9 is fixedly connected with a number of linear array anti-slip strips 10. The anti-slip strips 10 are made of rubber. The elastic properties of the rubber material can also prevent hard compression from damaging the cable sheath. The linear array layout ensures that the clamping force is evenly distributed, so that the connecting line 3 can remain stable when subjected to external force, thereby improving the adaptability and protection effect of the clamp to cables of different diameters.

[0025] As an optional technical solution of this utility model, the top and bottom of the frame 6 are provided with connecting grooves 11. The two moving plates 8 are slidably connected to the frame 6 through the two connecting grooves 11. The connecting grooves 11 at the top and bottom of the frame 6 provide a clear sliding trajectory for the moving plates 8, ensuring that the two moving plates 8 move synchronously under the drive of the bidirectional lead screw 7, and avoiding uneven clamping force caused by deviation of the moving path.

[0026] As an optional technical solution of this utility model, the inner wall of the frame 6 is provided with two symmetrically arranged arc-shaped grooves 12. The arc-shaped clamping plate 9 is slidably connected to the frame 6 through the arc-shaped grooves 12. The sliding cooperation between the arc-shaped grooves 12 on the inner wall of the frame 6 and the arc-shaped clamping plate 9 allows the clamping plate to be close to the cylindrical surface of the connecting line 3 along the arc trajectory, so as to achieve a more fitting arc-shaped wrapping.

[0027] As an optional technical solution of this utility model, a guide rod 13 is fixedly connected to the inner wall of the frame 6, and both moving plates 8 are slidably connected to the guide rod 13. The guide rod 13 is parallel to the bidirectional lead screw 7. During the lead screw transmission process, the moving plate 8 can offset the radial component force through the guide rod 13, and avoid the lateral force generated by the rotation of the lead screw causing the moving plate 8 to tilt or jam, thereby ensuring that the two arc-shaped clamping plates 9 move smoothly and synchronously.

[0028] As an optional technical solution of this utility model, the bottom of the frame 6 is rotatably connected to a control knob 14 via a bearing. The top of the control knob 14 is fixedly connected to the bottom of the bidirectional lead screw 7. The linkage design between the control knob 14 and the bidirectional lead screw 7 converts the rotational motion into the linear motion of the moving plate 8, allowing the clamping or loosening of the connecting line 3 to be achieved with one hand, significantly reducing the difficulty of operation. The bearing reduces the frictional resistance when the knob is rotated.

[0029] As an optional technical solution of this utility model, the outer surface of the internal threaded sleeve 4 is fixedly connected with a plurality of circumferentially arrayed reinforcing ribs 15. All reinforcing ribs 15 are fixedly connected to the set-top box body 1. By increasing the connection area with the set-top box body 1, the reinforcing ribs 15 on the outer surface of the internal threaded sleeve 4 distribute the force at the threaded connection to the set-top box shell, effectively enhancing the torsional strength and deformation resistance of the internal threaded sleeve 4. The circumferential array layout ensures that the reinforcing ribs 15 are evenly distributed around the circumference of the threaded sleeve, resisting impacts from external forces in different directions.

[0030] A special fixture for assembling set-top box antennas, the working principle of which is as follows:

[0031] 1): Insert the antenna connector 2 into the back of the set-top box body 1, and rotate the external thread tube 5 to make it tightly engage with the internal thread sleeve 4. This ensures that the axis of the antenna connector 2 is aligned with the internal thread sleeve 4, avoiding misalignment or tilting when manually tightening.

[0032] 2): The frame 6 is threadedly connected to the internal thread sleeve 4 through the external thread tube 5. At this time, rotating the control knob 14 drives the bidirectional lead screw 7 to rotate, which drives the two moving plates 8 to move towards each other along the guide rod 13, so that the arc-shaped clamping plate 9 clamps the connecting line 3.

[0033] 3): The linear array of rubber anti-slip strips 10 increases the friction of the contact surface, which can effectively prevent the connecting line 3 from sliding or twisting when it is pulled by external force.

[0034] In summary, this set-top box antenna assembly fixture achieves precise fixation of the antenna connector 2 to the set-top box body 1 through the threaded engagement of the inner threaded sleeve 4 and the outer threaded tube 5. During installation, the antenna connector 2 is inserted into the back of the set-top box body 1, and the outer threaded tube 5 is rotated to ensure a tight engagement with the inner threaded sleeve 4. This ensures that the axis of the antenna connector 2 is aligned with the inner threaded sleeve 4, avoiding misalignment or tilting that may occur during manual tightening. The frame 6 is threadedly connected to the inner threaded sleeve 4 through the outer threaded tube 5. At this time, rotating the control knob 14 drives the bidirectional lead screw 7 to rotate, causing the two moving plates 8 to move towards each other along the guide rod 13, so that the arc-shaped clamping plate 9 clamps the connecting wire 3. This structure improves the connection stability from two dimensions: interface tightening and cable fixation, through the rigid constraint of the threaded connection and the flexible fixation of the clamping mechanism. It prevents signal interruption caused by incomplete tightening of the interface or cable shaking. The anti-slip strip 10 and the arc-shaped clamping plate 9 of this fixture further enhance the fixing effect on the connecting wire 3. The inner wall of the arc-shaped clamping plate 9 fits against the cylindrical surface of the connecting wire 3. The linear array of rubber anti-slip strips 10 increases the friction of the contact surface, effectively preventing the connecting wire 3 from sliding or twisting when subjected to external force. The guide rod 13 is set parallel to the bidirectional lead screw 7, providing a stable sliding guide for the moving plate 8, ensuring that the two arc-shaped clamping plates 9 move synchronously and apply clamping force evenly, avoiding damage to the cable sheath due to uneven force. In addition, the reinforcing rib 15 enhances the connection strength between the internal threaded sleeve 4 and the set-top box body 1, preventing deformation of the threaded connection due to long-term force, thereby ensuring the reliability of the entire clamping system. This allows the connection between the antenna connector 2 and the set-top box body 1 to withstand both physical vibration and accidental pulling during daily use, significantly improving the stability and service life of the set-top box antenna after assembly.
