Description

Technical Field

[0001] The utility model relates to a high-speed transmission cable used in a server. Background Art

[0002] A server is a type of computer that runs faster, has a higher load, and is more expensive than an ordinary computer. The server provides computing or application services to other clients in the network. The server has high-speed CPU and GPU computing capabilities, long-term reliable operation capabilities, and better scalability. In server system design, high-speed signals are often interconnected between boards using gold fingers or high-speed cables. With the development of server technology, the requirements for signal delay and loss are more stringent. The inter-board interconnection solution of ordinary gold fingers can no longer meet most high-speed signal inter-board interconnection requirements. High-speed cables have gradually become the mainstream solution for high-speed signal inter-board interconnection in server systems due to their strong versatility, good SI performance, and customizability.

[0003] Existing high-speed cables usually include conductors, insulation layers, shielding layers, and drain wires. The insulation layer is cylindrical and wrapped around the conductor. In order to increase strength and prevent deformation from affecting the conductor, the insulation layer usually has a larger diameter. The drain wire is directly arranged outside the insulation layer, making the wire width larger. Therefore, existing high-speed signal cables have the disadvantages of slow speed and large size.

[0023] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0024] Depend on Figure 1 As shown, a high-speed transmission cable applied to a server comprises:

[0025] Conductor 1, used for signal transmission;

[0026] Shielding layer 2, used for signal shielding;

[0027] Drain wire 3, for ground connection;

[0028] The inner lining layer 4 is arranged inside the shielding layer 2; the drainage line 3 is arranged outside the inner lining layer 4 and is limited by the inner lining layer 4;

[0029] The insulating layer 5 is coated on the conductor 1, and a plurality of transmission holes 51 are arranged along the axial direction of the cable on the insulating layer 5. The beneficial effect of the utility model is that the transmission holes are arranged on the insulating layer, and the optimal characteristics of air conduction are utilized to reduce the attenuation of the signal and improve the transmission rate; the inner layer is arranged to limit the position of the drainage line to avoid deformation due to upward and downward movement, and also plays the effect of reducing the width of the wire. The utility model also has the advantages of simple structure, small size, faster signal transmission than the original, and long service life.

[0030] The transmission holes 51 are 6-12 in number, and are evenly arranged on the insulating layer 5 in the circumferential direction and arranged around the conductor 1 in the radial section. Hollow transmission holes are arranged to replace the insulating layer processed by the solid process in the prior art, which reduces the outer diameter of the wire and, by utilizing the optimal characteristics of air conduction, reduces signal attenuation and improves the transmission rate, and the transmission rate is increased from 32GT / S to 64GT / S.

[0031] The transmission holes 51 are arranged in a circular or fan-shaped manner. The transmission holes arranged in a circular or fan-shaped manner can reasonably utilize the space on the insulating layer, and multiple hollow transmission holes can be arranged as much as possible, and the optimal characteristics of air conduction can be utilized on the original basis to improve the signal transmission rate. At the same time, the circular and fan-shaped arrangements have better strength support, and the outer diameter of the insulating layer can be reduced, and the conductor can still be reliably supported and protected to avoid deformation.

[0032] The inner quilt layer 4 is provided with a positioning groove 41, and the drainage line 3 is arranged in the positioning groove 41. Specifically, the outer surface of the inner quilt layer 4 is recessed inward to form the positioning groove 41, and the drainage line 3 is arranged in the positioning groove 41, and the positioning groove 41 is arranged in an arc shape. More specifically, there are two drainage lines 3, and the two drainage lines 3 are arranged at both ends of the inner quilt layer 4, and the inner quilt layer 4 is flat. The special-shaped hole digging process is adopted to dig an arc-shaped positioning groove on each side of the inner quilt layer to position the drainage line, so as to avoid the drainage line from moving up and down and deforming, and at the same time, it also has the effect of reducing the width of the wire and reducing the volume of the product.

[0033] There are two conductors 1, each of which is covered with the insulating layer 5. Specifically, the insulating layer 5 is arranged in a circular shape, and the thickness of the insulating layer 5 is not greater than 0.25 mm, and the diameter of the transmission hole 51 is not greater than 0.15 mm. Such a structure ensures product strength, reduces volume, and reduces cost.

[0034] The utility model further comprises a coating layer 6, and the coating layer 6 is coated on the outside of the shielding layer 2. Specifically, the distance between the two ends of the coating layer 6 is not greater than 1.6 mm. That is, the maximum outer diameter of the cable is not greater than 1.6 mm. Such a structure makes the product have a long service life and a small product volume.
