Description

Technical Field

[0001] The utility model belongs to the technical field of signal cables, and specifically refers to a composite LVDS cable structure for a HSD (PoH) connector. Background Art

[0002] LVDS is currently the mainstream transmission mode for digital video signals and is mainly used in notebook computers, car computers, industrial computers, etc.

[0003] The data transmission unit and power supply unit of the traditional automotive LVDS cable dedicated to HSD (PoH) connector are separated independently. Figure 1 As shown, the power supply unit structure has no metal shielding layer, and the power supply part of the structure is exposed, which is easy to cause wear and short circuit. At the same time, the power supply part has no metal shielding layer, which is easy to cause signal interference to the data transmission unit, affecting the transmission performance and power supply failure. Moreover, the power supply line part is composed of two exposed single-core wires, which are connected to the HSD connector board end, which is easy to cause wear and short circuit failure of the power line.

[0007] Each of the data wire cores is a 1.20 mm data wire core composed of a 7 / 0.16 conductor and a PP insulation layer. Four of the wire cores are star-twisted to form a data transmission unit. A first metal tape is wound around the outer surface of the data transmission unit, and a first shielding layer is woven on the outer layer of the first metal tape.

[0008] The first shielding layer and the two power lines are closely assembled, and after being assembled, a layer of the second metal tape is wound around the outer surfaces of the first shielding layer and the two power lines.

[0009] The outer layer of the second metal tape is braided with a layer of the second shielding layer;

[0010] A sheath layer is disposed outside the second shielding layer.

[0011] Furthermore, the first shielding layer and the second shielding layer are both made of tinned braided wire.

[0012] Furthermore, the sheath layer is made of PVC material.

[0013] The advantages of the utility model are:

[0014] 1. Increase the protection of power lines:

[0015] The data transmission unit and the power supply unit are integrated in one sheath layer, which effectively protects the power line and can effectively reduce power supply failures.

[0016] 2. Improve anti-interference ability:

[0017] The use of a double metal shielding layer effectively improves EMI performance, thereby ensuring signal transmission stability.

[0018] 3. Improved the structural stability of the cable:

[0025] like Figure 2 As shown, a composite LVDS cable structure for a HSD (PoH) connector includes: four data wire cores, a first metal tape 31, a first shielding layer 41, two power wires 7, a second metal tape 32, a second shielding layer 42, and an outer sheath layer 5;

[0026] Each data wire core is a 1.20 mm data wire core composed of a 7 / 0.16 conductor 1 and a PP insulation layer 2. Four wire cores are star-twisted into a data transmission unit 6. A first metal tape 31 is wound around the outer surface of the data transmission unit 6. A first shielding layer 41 (using tinned braided wire) is woven on the outer layer of the first metal tape 31 to increase the anti-interference ability of the cable.

[0027] The first shielding layer 41 and the two power lines 7 are closely assembled (the shielding layer is closely assembled with the power lines to minimize electromagnetic interference). After the assembly, a second metal tape 32 is wound around the outer surface of the first shielding layer 41 and the two power lines 7.

[0028] A second shielding layer 42 (using tinned braided wire) is braided on the outer layer of the second metal tape 32 to prevent EMI interference sources;

[0029] A sheath layer 5 is provided outside the second shielding layer 42, and the sheath layer 5 is made of PVC. The outer surface of the cable is covered with materials such as PVC to protect the cable and improve the strength and stability of the cable. The PVC sheath has the characteristics of high wear resistance, aging resistance, high temperature resistance and chemical corrosion resistance, and can effectively protect the cable.

[0030] The vehicle-use LVDS composite data cable structure of the utility model realizes the integration of data transmission unit, power supply unit and control unit. Compared with the traditional data transmission unit or power supply unit or control unit structure, as well as the protection of PVC sheath, the structure is compact, and the anti-interference ability, strength and stability of the cable can be more effectively improved, ensuring the stability and reliability of signal transmission. By integrating the original data transmission unit and power supply unit part, and coordinating the technical means such as metal wrapping tape and double metal braided shielding layer and PVC sheath, the defects of the traditional LVDS cable are overcome, and the advantages of reducing signal interference, improving signal transmission quality and increasing the stability and reliability of the cable are achieved.

[0031] The utility model combines the power supply part, control and data communication to form a composite cable structure for automobiles. This compact structure can make the wire more stable, and at the same time can reduce the overall wire structure size, reduce the consumption of sheath materials, save costs, and meet the requirements of lightweight use. In addition, this structure can also increase the strength, durability and signal transmission stability of the cable, making it more suitable for use in the automotive environment.

[0032] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
