Description

Technical Field

[0001] The utility model relates to the technical field of set - top boxes, and specifically relates to a digital set - top box. Background Art

[0002] In the current technical field of digital set - top boxes, with the popularization of multimedia services such as high - definition TVs, smart TVs, and Internet TVs, the digital set - top box, as a bridge connecting users with digital radio and television signals and Internet content, has increasingly diverse and complex designs and functions. However, while improving the user experience and service quality, some basic but crucial design problems still need to be solved urgently. One of them is the inconvenience of wire clamping and fixing and position adjustment.

[0003] Traditional or existing digital set - top boxes often face challenges in wire management when wiring and connecting various peripherals (such as TVs, audio systems, network devices, etc.). On the one hand, due to the relatively fixed wire interface design of the set - top box and the lack of a flexible clamping mechanism, it is difficult to firmly clamp and fix the wires after insertion, and problems such as loosening and falling off are likely to occur, affecting the stable transmission of signals and the normal use of the device. On the other hand, even if the wires can be clamped, most of the existing clamping devices do not have a position adjustment function. When users need to adjust the wire layout according to the actual installation environment or requirements, they often need to re - plug the wires, which is cumbersome and inefficient, and may even cause wear or damage to the interfaces.

[0004] Chinese Patent Publication No. CN221633876U discloses a wire - bundling structure of a set - top box. It slides and rivets a wire - bundling part one and a wire - bundling part two through a lower slider one and a lower slider two. The wire - bundling part one and the wire - bundling part two bundle the wires. The first screw rod and the second screw rod are provided, which can control the distance between the wire - bundling part one and the wire - bundling part two, so as to bundle wires with different diameters. During the whole wire - bundling process, the stability is good, the efficiency is improved, the structure is simple and easy to operate, and the use value is improved.

[0005] However, in actual use, the above - mentioned structure is not convenient for adjusting the distance between the clamped wires. And if it is necessary to re - adjust the connection position of the wires, it may cause unnecessary tensile stress on the wires, thereby reducing the service life of the wires. Moreover, the position of the wires after clamping is fixed, resulting in heat accumulation of the wires and increasing the obstruction to the heat dissipation channels. Summary of the Utility Model

[0030] When it is necessary to firmly fix the wire 3, first slide the moving frame 42 in the horizontal linear direction, and then the distance between the moving frame 42 and the wire 3 can be adjusted. When it is necessary to clamp the wire 3, insert the guide into the clamping blocks 44, and then the clamping blocks 44 can clamp and fix the wire 3. Then, through the fine-tuning fixing mechanism 5, the wire 3 and the displacement blocks 43 after clamping can be slid in the horizontal linear direction. After sliding, the distance between the clamped wires 3 can be adjusted, achieving the adjustment and fixation of the distance between the clamped wires 3, which can improve the heat dissipation efficiency, reduce the unnecessary tensile stress on the wire 3, and extend the service life of the wire 3.

[0031] See Figure 3 As shown, the fixing and adjusting mechanism 4 further includes a limiting rod 45, a sliding groove 46 and a mounting frame 47; the limiting rod 45 is provided on the mounting block 41 and has a pair.

[0036] When it is necessary to move the clamped wire 3, first move the displacement block 43 along the sliding groove 46. During the movement of the displacement block 43, the telescopic spring 49 in the stroke chamber 52 can drive the card block 54 to always contact the fixed card plate 51, so that when the displacement block 43 moves, the card block 54 can be pressed against the fixed card plate 51, and the card block 54 can slide in a horizontal straight line direction along the stroke chamber 52 to limit the movement of the displacement block 43 in the sliding groove 46. When it is necessary to move the displacement block 43, pull the displacement block 43 again to fine-tune the distance of the displacement block 43, and then control the distance between each displacement block 43, so as to facilitate the control and adjustment of the distance between the clamped wires 3 to prevent them from sliding freely.
