Description

Technical Field

[0001] This utility model relates to the field of signal transmission technology, specifically to a connection structure for broadcast television signal transmission lines with anti-interference capabilities. Background Technology

[0002] In the process of broadcast television signal transmission, the connection structure of the signal transmission line is crucial. The stability and anti-interference capability of the connection directly affect the quality of signal transmission. At present, the existing connection structure of broadcast television signal transmission lines often has weak anti-interference capability and is easily affected by external electromagnetic signals, radio frequency signals, etc., which leads to problems such as signal attenuation and distortion, affecting the normal playback of broadcast television programs.

[0003] However, the existing connection structure of broadcast television signal transmission lines still has certain problems:

[0004] The connecting components in the existing broadcast television signal transmission line connection structure are mostly made of ordinary metal materials and lack effective shielding measures. This allows external electromagnetic waves, radio signals and other interference sources to easily penetrate the signal transmission line, causing problems such as signal distortion and increased noise, which seriously affects the broadcast quality of broadcast television.

[0005] Therefore, we proposed a connection structure for broadcast television signal transmission lines with anti-interference capabilities to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a connection structure for broadcast television signal transmission lines with anti-interference capabilities, in order to solve the problem that most of the connecting components in the broadcast television signal transmission line connection structures mentioned in the background art are made of ordinary metal materials and lack effective shielding measures, which allows external electromagnetic waves, radio signals and other interference sources to easily invade the signal transmission line, causing signal distortion, increased noise and other problems, which seriously affect the broadcast quality of broadcast television.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a broadcast television signal transmission line connection structure with anti-interference capability, comprising a first signal transmission cable and a rotary connector, wherein one end of the first signal transmission cable is movably connected to the rotary connector, one end of the rotary connector is fixed with a first insulating fastener, one end of the first insulating fastener is fixed with a first connector, a second signal transmission cable is provided on one side of the first signal transmission cable, one end of the second signal transmission cable is fixed with a second insulating fastener, one end of the second insulating fastener is fixed with a second connector, the outer surface of the first connector is covered with a first shielding component, and the outer surface of the second connector is covered with a second shielding component.

[0008] By adopting the above technical solution, a continuous metal shielding layer is formed by covering the outer surfaces of the first and second connectors with the first and second shielding components, respectively. The conductivity of the shielding layer guides external electromagnetic interference to the grounding system and prevents internal signals from radiating outward. This achieves an anti-interference mechanism of "shielding-isolation-grounding", ensuring that broadcast television signals are protected from signal attenuation, distortion, or crosstalk caused by mechanical rotation or complex electromagnetic environment when passing through the rotary connector, thus guaranteeing the stability and reliability of high-definition / ultra-high-definition video transmission.

[0009] Preferably, the first connector includes a male connector housing, an internally threaded coil is provided on the inner side of the male connector housing, and a signal transmission pin is fixed in the middle of the male connector housing.

[0010] Using the above technical solution, the internal threaded coil of the male connector shell tightly engages with the female connector shell through a mechanical thread structure, forming a 360° surrounding metal shielding cavity. At the same time, the signal transmission pin makes elastic contact with the female connector socket, achieving low-impedance signal transmission. The two work together to isolate external electromagnetic interference. The internal threaded coil enhances the mechanical connection stability and expands the shielding contact area, while the signal transmission pin ensures the complete transmission of high-frequency signals such as K / K video. Together, they guarantee the anti-interference performance and transmission quality of broadcast television signals in dynamic connection scenarios.

[0011] Preferably, the second connector includes a female connector housing, the outer surface of which is provided with an external threaded coil, and the middle part of which is provided with a signal transmission hole.

[0012] Using the above technical solution, the external threaded coil of the female connector shell and the internal thread of the male connector form a helical mechanical engagement, which expands the coverage of the shielding layer through the metal contact surface. At the same time, the elastic spring in the signal transmission hole is in close contact with the male connector pin, creating a low-impedance signal path. The external threaded coil enhances the connection's shock resistance and achieves 360° electromagnetic shielding continuity. The signal transmission hole ensures stable transmission of high-frequency signals in dynamic connections. This dual mechanism protects broadcast television signals from external interference.

[0013] Preferably, the internal threaded coil of the male head housing and the external threaded coil of the female head housing form a corresponding threaded fastening connection.

[0014] Using the above technical solution, the male internal thread coil and the female external thread coil form a mechanical interlocking structure through helical engagement. The threaded bevel extrusion generates radial pressure on the metal contact surface, eliminating microscopic gaps and expanding the overlapping area of ​​the shielding layer to construct a continuous conductive path. The threaded fastening achieves a vibration- and impact-resistant mechanical connection, ensuring the stability of high-frequency signal transmission. The metal threaded contact forms a low-impedance electromagnetic shielding ring, effectively suppressing the coupling and penetration of external electromagnetic interference into the signal transmission path.

[0015] Preferably, the signal transmission pin is adapted to the signal transmission hole, and both the outer surface of the signal transmission pin and the inner end face of the signal transmission hole are coated with a gold-plated structure.

[0016] By adopting the above technical solution, the gold-plated structure, through its excellent conductivity and chemical stability, ensures that the signal transmission pin and the signal transmission hole form a low-impedance, high-reliability conductive path when in elastic contact. At the same time, it prevents the contact resistance from increasing due to oxidation or wear during long-term use. The gold plating layer significantly improves the stability of signal transmission, reduces signal attenuation and distortion, and extends the service life of the connector in harsh environments, ensuring long-term transmission quality.

[0017] Preferably, the first shielding component includes an outer shielding layer and an inner shielding layer, with a shielding filler layer filling the space between the outer shielding layer and the inner shielding layer. The inner shielding layer is a copper mesh shielding layer, the outer shielding layer is an aluminum foil shielding layer, and the shielding filler layer is a graphene filler layer.

[0018] Using the above technical solution, the outer shielding layer achieves primary shielding by reflecting high-frequency electromagnetic waves, the inner shielding layer absorbs low-frequency interference using a fine mesh structure, and the middle graphene filling layer fills the gaps and forms a continuous conductive path with its high conductivity. The three work together to construct a multi-level electromagnetic protection system. The layered shielding structure can suppress interference in different frequency bands in a differentiated manner. Graphene enhances the continuity of shielding and improves flexibility, ensuring stable transmission of broadcast television signals in complex electromagnetic environments, while also taking into account the flexibility of cable bending.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. The first shielding component uses an aluminum foil outer shielding layer to reflect high-frequency electromagnetic waves, a copper mesh inner shielding layer to absorb low-frequency noise, and a graphene filling layer in the middle to fill microscopic gaps with high conductivity, forming a triple protection of "reflection-absorption-continuous conduction", which effectively suppresses the coupling and penetration of external interference into broadcast television signals; at the same time, the male and female outer shells are connected by threads to achieve 360° gapless metal shielding coverage, and the gold-plated structure of the signal transmission pin and signal transmission hole provides low-impedance contact, ensuring stable transmission of high-frequency signals in dynamic connection scenarios and significantly reducing the risk of signal attenuation and distortion.

[0021] 2. The helical engagement of the internal and external threaded coils generates radial preload, eliminating contact loosening caused by vibration or impact and ensuring connection reliability for long-term use; the high corrosion resistance of the gold plating layer allows the signal transmission pin and signal transmission hole to adapt to harsh environments such as high humidity and salt spray, extending their service life; in addition, the flexibility of the graphene filling layer allows the shielding components to bend with the cable without breaking, ensuring shielding integrity in complex wiring scenarios, comprehensively improving the stability and maintenance convenience of the broadcast television signal transmission system in dynamic applications such as outdoor broadcasting and mobile vehicle-mounted systems.

[0028] 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.

[0029] Please see Figures 1-5This utility model provides a technical solution: a broadcast television signal transmission line connection structure with anti-interference capability, including a first signal transmission cable 1 and a rotary connector 2. One end of the first signal transmission cable 1 is movably connected to the rotary connector 2. One end of the rotary connector 2 is fixed with a first insulating fastener 3. One end of the first insulating fastener 3 is fixed with a first connector 4. A second signal transmission cable 5 is provided on one side of the first signal transmission cable 1. One end of the second signal transmission cable 5 is fixed with a second insulating fastener 6. One end of the second insulating fastener 6 is fixed with a second connector 7. The outer surface of the first connector 4 is covered with a first shielding component 8, and the outer surface of the second connector 7 is covered with a second shielding component 9. The first connector 4 includes a male connector housing 401, with an internally threaded coil 402 on its inner side, and a signal transmission pin 403 fixed in the middle of the male connector housing 401. The second connector 7 includes a female connector housing 701, with an externally threaded coil 702 on its outer surface, and a signal transmission hole 703 in the middle of the female connector housing 701. The internal threaded coil 402 of the male connector housing 401 and the external threaded coil 702 of the female connector housing 701 form a corresponding threaded fastening connection. The signal transmission pin 403 is adapted to the signal transmission hole 703, and both the outer surface of the signal transmission pin 403 and the inner end face of the signal transmission hole 703 are coated with a gold-plated structure. The first shielding assembly 8 includes an outer shielding layer 801 and an inner shielding layer 802, with a shielding filler layer 803 filling the space between the outer shielding layer 801 and the inner shielding layer 802. The inner shielding layer 802 is a copper mesh shielding layer, the outer shielding layer 801 is an aluminum foil shielding layer, and the shielding filler layer 803 is a graphene filler layer.

[0030] The internal threaded coil 402 of the male connector housing 401 and the external threaded coil 702 of the female connector housing 701 form a helical fastening connection. This not only constructs a continuous conductive shielding cavity through the 360° circumferential contact of the metal threads, but also utilizes the pressure of the threaded bevel to eliminate contact gaps and enhance mechanical shock resistance. The signal transmission pin 403 and the signal transmission hole 703 achieve low-impedance elastic contact through a gold-plated structure. The high conductivity and corrosion resistance of the gold plating layer ensure stable transmission of high-frequency signals in dynamic connections, reduce signal attenuation and distortion, extend the service life of the connector in harsh environments, and guarantee long-term transmission quality. The shielding component 8 uses an aluminum foil outer shielding layer 801 to reflect high-frequency electromagnetic waves, a copper mesh inner shielding layer 802 to absorb low-frequency interference, and an intermediate shielding filling layer 803 to fill microscopic gaps with its high carrier mobility, forming a triple anti-interference mechanism of "reflection-absorption-continuous conduction". This effectively suppresses the coupling and penetration of external electromagnetic interference into the signal transmission path, while ensuring the shielding integrity of the cable in scenarios with frequent bending or rotation. This ensures stable transmission of broadcast television signals in complex electromagnetic environments, while also taking into account the flexibility of cable bending, ultimately achieving high-quality and long-life transmission of broadcast television signals in complex electromagnetic environments.

[0031] Working principle: For this type of anti-interference broadcast television signal transmission line connection structure, during operation, the internal threaded coil 402 of the male connector housing 401 and the external threaded coil 702 of the female connector housing 701 form a tight mechanical connection through spiral engagement, so that the metal threaded surfaces are completely fitted to construct a continuous conductive shielding cavity, blocking the intrusion path of external electromagnetic interference; at the same time, when the signal transmission pin 403 is inserted into the signal transmission hole 703, its surface gold-plated structure and the gold-plated end face inside the hole form a low-impedance conductive path through elastic contact, ensuring stable transmission of high-frequency broadcast television signals; in the first shielding component 8, the aluminum foil outer shielding layer 801 reflects high-frequency interference, the copper mesh inner shielding layer 802 absorbs low-frequency noise, and the shielding filling layer 803 fills the microscopic gaps through high carrier mobility, forming a triple electromagnetic protection of "reflection-absorption-continuous conduction", ultimately realizing anti-interference transmission of signals in dynamic connections and complex electromagnetic environments.
