Description

Technical Field

[0001] This utility model relates to the field of transmission cable technology, specifically to a multi-shielded signal transmission cable for communication equipment. Background Technology

[0002] Transmission cables are cables used to transmit electrical signals or data. They consist of one or more conductors and are typically covered with insulation and other auxiliary layers to protect the signal from interference and damage during transmission. These cables are widely used in communications, computer networks, audio and video transmission, industrial control, and power transmission. They can support a variety of signal types, from low to high frequencies and from low to high speeds, ensuring signal stability and reliability. The design and material selection of transmission cables depend on the required transmission rate, distance, environmental conditions, and electromagnetic compatibility requirements.

[0003] Authorization announcement number CN217562291U discloses a data transmission cable with the following technical solution: "It includes a plurality of parallel-arranged conductors, a plastic layer integrally formed around the plurality of conductors, and a metal shielding film covering the outside of the plastic layer; the metal shielding film has a first shielding film and a second shielding film that are separated from each other and arranged oppositely, the first shielding film and the second shielding film covering opposite sides of the plastic layer in a direction perpendicular to the direction of conductor arrangement." The advantages are: shielding against external interference and ensuring the stability of signal transmission of the conductors; furthermore, the fact that the two sides of the metal shielding film do not extend beyond the plastic layer not only makes the covering operation of the metal shielding film more convenient, but also makes it suitable for mass production and improves production efficiency.

[0004] The above technical solution has the following defects: it lacks a protective structure for the cable. When the cable is affected by external factors during use, it is easily damaged by collision or friction with objects. At the same time, it is easily affected by environmental factors, which can lead to a decrease in insulation performance and thus short circuit. Therefore, a multi-shielded signal transmission cable for communication equipment is proposed to solve the problems mentioned above. Utility Model Content

[0013] Furthermore, the limiting mounting strip has two threaded grooves inside, the locking screw is threaded into the inside of the threaded groove, the embedded block has a groove inside, and the locking screw is located inside the groove.

[0014] Furthermore, the core conductor layer includes a conductor layer and four core conductors, which are vertically distributed inside the conductor layer.
