Description

Technical Field

[0001] The utility model relates to the field of cables, and more specifically to a computer cable with total and divided shielding layers that is resistant to pressure and torsion. Background Art

[0002] Computer cables play a vital role in the computer and network fields. Computer cables are not only channels for data transmission and power supply, but also media for device connection and signal transmission. With the continuous development of computer technology and network technology, the performance and quality of computer cables will continue to improve.

[0003] Existing computer cables lack effective protective structures and have poor pressure resistance. When the cables are subjected to mechanical compression, heavy objects, etc., the insulation layer or conductor of the cables may be damaged, causing the cables to fail or degrade in performance. Some computer cables have weak torsion resistance and cannot withstand frequent torsion or twisting. In application scenarios where cables need to be frequently moved, bent, or twisted, the cables may be twisted and deformed, or internally broken, leading to connection failures. In addition, ordinary computer cables have insufficient shielding performance and are easily affected by external electromagnetic interference, resulting in distortion or loss of data signals, thereby reducing the accuracy of data transmission.

The tensile cable core 6 includes a tensile steel wire 6.1 and a tensile sheath 6.2 wrapping the tensile steel wire 6.1. The computer cable core 5 includes a sub-item shielding layer 5.1 and an inner sheath 5.2 located in the sub-item shielding layer 5.1.

The outer sheath 4 is a mica tape sheath, and the inner sheath 5.2 is a polyurethane sheath.

[0029] The multiple first grooves are divided into two groups, and the multiple first grooves in each group are distributed in a row with equal intervals, and there is a first branch portion 7.2 between any two adjacent first grooves in each group; the computer cable core 5 and the first grooves each have 14; the tensile cable core 6 and the second groove each have 2, and the two second grooves are respectively located at the two ends of the skeleton unit 7, and there is a second branch portion 7.3 between the second groove and the adjacent first groove; the first branch portion 7.2 and the second branch portion 7.3 both extend along the length direction of the cable; the total shielding layer 3 is a copper wire braided shielding layer, and the sub-shielding layer 5.1 is an aluminum-plastic composite tape shielding layer.

[0030] Working principle: The computer cable of the present application has multiple computer cable cores, so it is suitable for modern computer systems that need to process large amounts of data. Since the skeleton unit has a substrate part, and the substrate part has a first and a second branch part, it has a good anti-torsion effect, so that the cable can still maintain stable performance under bending, twisting and other conditions, ensuring the transmission quality of the signal. The tensile cable cores on both sides have a good tensile effect, thereby enhancing the tensile strength of the cable, making the cable less likely to be damaged when subjected to tension. The two wrapping units achieve a good pressure-resistant protection effect, thereby improving the pressure-resistant performance of the cable and ensuring that the cable protects the internal structure under external impact and extrusion. The total shielding structure achieves a better shielding effect, which can effectively shield electromagnetic interference from the internal and external environments and improve the transmission quality of the signal.

[0031] During the specific assembly, first, place the computer cable cores in the first grooves corresponding to the skeleton unit, and at the same time, place the tensile cable cores in the corresponding second grooves. The tensile cable cores thus provide additional tensile strength for the cable, increasing the durability and reliability of the cable. Then use mica tape to tightly wrap the skeleton unit and multiple cable cores together. The mica tape has good insulation and high temperature resistance, which can protect the cable core from the influence of the external environment while ensuring the stability and safety of the cable. Then wrap the two wrapping units on the overall shielding layer. During the wrapping process, ensure that the two ends of one of the wrapping units are respectively abutted against the two ends of the other wrapping unit to form a complete pressure-resistant protective layer. Finally, make the outer sheath to protect the internal structure.

[0032] Although the present invention has been illustrated and described with respect to preferred embodiments, it should be understood by those skilled in the art that various changes and modifications may be made to the present invention without departing from the scope of the present invention as defined by the claims.
