Description

Technical Field

[0001] This utility model relates to the field of LVDS screen cable technology, specifically to an LVDS screen cable that resists signal interference. Background Technology

[0002] LVDS (Low Voltage Differential) screen cables are digital signal transmission lines used in LCD display devices. LVDS, or Low Voltage Differential Signaling Technology, is a differential signaling technology characterized by low power consumption, low bit error rate, low crosstalk, and low radiation. An LVDS screen cable typically consists of three parts: VCC (power line, usually red), GND (ground line, usually black), and differential signals, usually multiple sets of blue and white twisted pairs. Depending on the bit depth, LVDS screen cables are mainly classified as single 6-bit, dual 6-bit, single 8-bit, and dual 8-bit types. They are widely used in connecting screens and motherboards in LCD monitors, LCD TVs, large LCD display walls, industrial control and medical equipment, and industrial, security, and financial fields, and are widely used in LCD monitors of 17 inches and above.

[0003] Employing extremely low voltage swing and high-speed differential data transmission, this cable boasts low power consumption, achieving speeds exceeding 155 Mbps. The differential transmission method effectively reduces electromagnetic interference, maintaining signal stability and accuracy over long distances. The connection cable offers stable and reliable contact, withstanding over 1000 insertion / removal cycles and a wide temperature range from -20°C to 80°C. As a high-performance digital signal transmission line, LVDS screen cables play a crucial role in LCD devices. Their low power consumption, high transmission rate, low noise, and long-distance transmission capabilities make them an indispensable part of modern electronic devices.

[0004] However, since the power lines, ground lines and differential signal lines inside the LVDS screen cable are mixed together, the differential signal lines are easily affected by electromagnetic interference from external devices and the power lines and ground lines, which leads to interference with signal transmission. In view of this, this application proposes an LVDS screen cable that is resistant to signal interference. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an LVDS screen cable that resists signal interference. It has advantages such as preventing signal lines from being interfered with by power lines and ground lines. It solves the problem that the differential signal lines are easily affected by electromagnetic interference from external devices, power lines, and ground lines because the power lines, ground lines, and differential signal lines inside the LVDS screen cable are mixed together, which leads to interference with signal transmission.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an LVDS screen cable with anti-signal interference, comprising a corrosion-resistant outer shell, wherein a power branch shell and a signal branch shell are fixedly installed inside the corrosion-resistant outer shell, and a signal line is fixedly installed inside the signal branch shell;

[0007] The power branch housing includes an insulating power sheath on the surface and a power shielding layer inside the insulating power sheath, and the signal branch housing includes an insulating signal sheath on the surface and a signal shielding layer inside the insulating signal sheath.

[0008] Furthermore, the signal line includes a surface signal protection sheath, and a signal core is fixedly installed inside the signal protection sheath.

[0009] Furthermore, a power cord is fixedly installed inside the power supply branch housing, and a ground wire is fixedly installed inside the power supply branch housing.

[0010] Furthermore, the power cord includes a power protection sheath on its surface, and a power core is fixedly installed inside the power protection sheath.

[0011] Furthermore, the ground wire includes a surface protective sheath, and a ground core is fixedly installed inside the protective sheath.

[0012] Furthermore, a signal filling layer is fixedly installed inside the signal branch housing and in the gap between the signal lines, and a power filling layer is fixedly installed inside the power branch housing and in the gap between the power lines and the ground lines.

[0013] Furthermore, branch heads are fixedly installed at both ends of the anti-corrosion shell, and a plug is fixedly installed on one side of the branch heads.

[0014] Compared with the prior art, this utility model provides an LVDS screen cable that resists signal interference, which has the following beneficial effects:

[0015] This anti-interference LVDS screen cable separates the power and ground lines from the signal lines, encasing them inside the power branch shell and the signal branch shell respectively. By setting signal shielding layers and power shielding layers inside the power branch shell and the signal branch shell respectively, the power and ground lines are isolated from the signal lines, preventing the signal lines from being affected by electromagnetic interference. This solves the problem that when the power lines, ground lines, and differential signal lines are mixed together inside the LVDS screen cable, the differential signal lines are easily affected by electromagnetic interference from external devices and the power and ground lines, leading to signal transmission interference.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 An LVDS screen cable with anti-signal interference includes a corrosion-resistant outer shell 1. A power branch shell 2 and a signal branch shell 3 are fixedly installed inside the corrosion-resistant outer shell 1. A signal cable 4 is fixedly installed inside the signal branch shell 3. The corrosion-resistant outer shell 1 provides corrosion protection, encasing the power branch shell 2 and the signal branch shell 3 together.

[0023] The power branch housing 2 includes an insulating power sheath 21 on the surface and a power shielding layer 22 inside the insulating power sheath 21. The signal branch housing 3 includes an insulating signal sheath 31 on the surface and a signal shielding layer 32 inside the insulating signal sheath 31. The insulating power sheath 21 and the insulating signal sheath 31 provide insulation.

[0024] The signal line 4 is wrapped inside the signal branch housing 3 and protected by two layers of shielding: the power shielding layer 22 and the signal shielding layer 32. This ensures that the signal line 4 is not affected by external electromagnetic interference and maintains stable signal transmission.

[0025] Secondly, the signal line 4 includes a surface signal protection sheath 41, and a signal core 42 is fixedly installed inside the signal protection sheath 41. The signal protection sheath 41 is made of insulating material and serves to protect the signal core 42. Multiple signal lines 4 are used to transmit signals.

[0026] Meanwhile, a power cord 5 is fixedly installed inside the power supply branch housing 2, and a ground wire 6 is fixedly installed inside the power supply branch housing 2. The power cord 5 is used to connect to the power supply, and the ground wire 6 is used for grounding connection.

[0027] The power cord 5 includes a protective sheath 51 on its surface, and a power core 52 is fixedly installed inside the protective sheath 51. The protective sheath 51 is made of insulating material and serves to protect the power core 52.

[0028] Secondly, the ground wire 6 includes a surface protective sheath 61, and a ground core 62 is fixedly installed inside the protective sheath 61. The protective sheath 61 is an insulating material, which serves to protect the ground core 62.

[0029] Meanwhile, a signal filling layer 7 is fixedly installed inside the signal branch housing 3 and in the gap between the signal line 4, and a power filling layer 8 is fixedly installed inside the power branch housing 2 and in the gap between the power line 5 and the ground line 6. Both the signal filling layer 7 and the power filling layer 8 are made of flame-retardant materials, which have a flame-retardant effect and prevent the LVDS screen cable from catching fire.

[0030] The anti-corrosion housing 1 has branch heads 9 fixedly installed at both ends, and a plug 10 fixedly installed on one side of the branch head 9. The branch heads 9 separate multiple signal lines 4, power lines 5 and ground lines 6, making it easy to connect to the connector of the plug 10, and the plug 10 connects to two devices.

[0031] In this embodiment, the power line 5 and ground line 6 are wrapped inside the power branch housing 2, and the signal line 4 is wrapped inside the signal branch housing 3, separating the power line 5 and ground line 6 from the signal line 4 to reduce electromagnetic interference. Furthermore, the dual protection of the power shielding layer 22 and the signal shielding layer 32 ensures that the signal line 4 is not subject to external electromagnetic interference, nor to electromagnetic interference from the power line 5 and ground line 6, thus maintaining stable signal transmission. The anti-corrosion housing 1 prevents the LVDS screen cable from being corroded, increasing the service life of the LVDS screen cable.
