Description

Technical Field

[0001] This utility model relates to the field of digital television terminal equipment technology, and in particular to an anti-disconnection structure for a set-top box. Background Technology

[0002] With the rapid development of digital television and network multimedia technologies, set-top boxes have become one of the core devices for home entertainment and information terminals. Set-top boxes typically have multiple external ports on the back, such as power ports, HDMI high-definition video ports, network ports, and USB ports, for connecting to power sources, televisions, networks, and external storage devices. In daily life, set-top boxes are usually placed in limited spaces such as TV cabinets. Their connecting cables (such as power cords and HDMI cables) are easily detached from the ports when accidentally pulled, moved, or touched by children or pets, leading to signal interruption and playback disruption, affecting the user's viewing experience. Current technology lacks an effective, easy-to-operate, and universally applicable anti-detachment structure for different cable connector sizes; therefore, an anti-detachment structure for set-top boxes is needed to meet this requirement. Utility Model Content

[0003] The purpose of this invention is to provide an anti-derailment structure for set-top boxes to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a set-top box anti-disconnection structure, comprising a set-top box body. One end of the set-top box body is provided with a display screen, and the other end is provided with several interfaces for connecting various cables. A cover is installed on the end of the set-top box body where the interfaces are located. The cover is designed to be open at both the connection point with the set-top box body and at its upper end, facilitating the introduction and laying of cables.

[0005] Inside the housing, at the end opposite the interface, several screws are rotatably connected. The number and position of the screws correspond to the interface on the set-top box body. One end of each screw extends to the outside of the housing and is fixedly fitted with a knob for easy external operation. Each screw is threaded with an adjustment plate. By rotating the knob, the screw can be driven to rotate, thereby moving the adjustment plate along the screw's axial direction.

[0006] Several springs are installed at one end of each adjusting plate near the interface. The other end of these springs is connected to a push plate, which is positioned near the interface. When the cable connector is inserted into the interface, the adjusting plate is moved towards the interface by turning a knob. The adjusting plate pushes the push plate through the springs, ultimately pressing the push plate firmly against the side of the cable connector. This utilizes the spring force and the pressure of the push plate to securely hold the cable connector within the interface, effectively preventing it from loosening.

[0007] To facilitate the insertion and arrangement of different cables, U-shaped slots are provided at the end of the cover away from the interface, the upper end of the adjusting plate, and the upper end of the push plate. Cables can easily pass through these U-shaped slots and enter the corresponding positions, and the push force of the push plate on the cable plug achieves the effect of preventing loosening.

[0008] Preferably, one end of the cover is provided with a circumferentially extending frame, which is fixedly connected to the end face of the set-top box body at the interface by screws. This connection method is stable and reliable, and facilitates disassembly and maintenance.

[0009] Preferably, the upper end of the cover is provided with a cap, which is movably connected to the end face of the frame via a hinge. The cap can be opened or closed, and when closed, it can prevent dust from entering the interior of the cover and make the appearance cleaner.

[0010] Preferably, a support base is provided on the bottom end of the cover, and the end of the screw away from the knob is rotatably connected to the support base. The support base provides stable distal support for the screw, ensuring smooth rotation.

[0011] Preferably, a guide rail is provided at the bottom end of the cover, and the cross-section of the guide rail is in the shape of an inverted trapezoid. The bottom ends of the adjusting plate and the push plate are slidably connected to the guide rail. The guide rail guides and limits the movement of the adjusting plate and the push plate, preventing them from deflecting or getting stuck during movement, and ensuring that they can only move linearly in a preset direction.

[0012] Preferably, the adjusting plate has a threaded hole adapted to the screw for threaded transmission. The push plate has a through hole larger than the outer diameter of the screw, allowing the push plate to move freely under the push of the spring without interfering with the screw.

[0013] The beneficial effects of this utility model are: In this invention, the adjustable push plate and spring assembly work together to apply continuous and stable lateral pressure to cable connectors of different lengths, firmly pressing them into the set-top box interface, effectively resisting accidental pulling from the outside and preventing the connectors from loosening.

[0014] This invention employs an independently adjustable screw, adjusting plate, and push plate structure, combined with spring elasticity compensation, enabling the structure to adapt to different types of cable connectors and exhibiting excellent versatility. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-5 A set-top box anti-drop-off structure mainly includes the set-top box body 1, display screen 2, interface 3, cover 4, screw 5, knob 6, adjustment plate 7, spring 8, push plate 9 and other components.

[0019] The set-top box body 1 has a display screen 2 on the front and multiple interfaces 3 on the back, such as HDMI interface, power interface, and USB interface. At the end where the interfaces 3 are located, a cover 4 with a circumferential frame 11 is fixed to the set-top box body 1 with screws. A cover 12 is hinged to the top of the cover 4, allowing it to open and close.

[0020] A guide rail 14 with an inverted trapezoidal cross-section is fixedly installed on the inner bottom surface of the cover 4. Inside the cover 4, opposite to the interface 3, a fastening mechanism is correspondingly provided behind each interface 3. This mechanism includes a longitudinally arranged screw 5, one end of which passes through the side wall of the cover 4 and is rotatably connected via a bearing; a knob 6 is installed at this end. The other end of the screw 5 is rotatably connected to a support base 13 fixed to the bottom surface of the cover 4.

[0021] An adjusting plate 7 is slidably mounted on the guide rail 14 via a groove on its bottom that matches the shape of the guide rail 14. The adjusting plate 7 has a threaded hole 15, forming a threaded pair with the screw 5. When the knob 6 is rotated, the screw 5 rotates, driving the adjusting plate 7 to move along the guide rail 14 toward or away from the interface 3.

[0022] On the side of the adjusting plate 7 facing the interface 3, multiple springs 8 are fixed. The other ends of these springs 8 are connected to a push plate 9. The bottom of the push plate 9 is also slidably connected to the guide rail 14 via a groove. The push plate 9 has a through hole 16, the diameter of which is larger than the outer diameter of the screw 5, to ensure that the push plate 9 is not interfered with by the screw 5 when it moves.

[0023] U-shaped slots 10 are provided on the end wall of the cover 4 away from the interface 3, on the top of each adjustment plate 7, and on the top of the push plate 9, for guiding and accommodating cables.

[0024] Working principle: Open the cover 12 on top of the housing 4. Insert the connectors of various cables (such as HDMI cables and power cords) into the corresponding interfaces 3 on the set-top box body 1. The cable body can be passed through the U-shaped slot 10 on the rear wall of the housing 4 and placed in the U-shaped slot 10 on the top of the adjustment plate 7 and the push plate 9. Rotate the corresponding knob 6 clockwise. The knob 6 drives the screw 5 to rotate. Since the adjustment plate 7 is connected to the screw 5 through the threaded hole 15 and its bottom is restricted from rotating by the guide rail 14, the adjustment plate 7 will move along the guide rail 14 towards the interface 3. When the adjustment plate 7 moves forward, the spring 8 pushes the push plate 9 forward together. When the push plate 9 contacts the cable connector that has been inserted into the interface 3, the cable plug is usually larger than the cable specification. Continue to rotate the knob 6, and the spring 8 will begin to be compressed. The elastic force of the spring 8 continues to act on the cable connector through the push plate 9, generating a force that presses it tightly against the inside of the interface 3, thereby achieving an anti-dislodgement effect. The elasticity of spring 8 can adapt to the dimensional tolerances of different connectors and provide a stable clamping force. When it is necessary to unplug the cable, rotate knob 6 counterclockwise, adjust plate 7 moves backward, the compression of spring 8 decreases, the pressure is released, and the cable connector can be easily pulled out.

[0025] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
