Description

Technical Field

[0001] The utility model relates to the technical field of cables, and more specifically to a finger sleeve for a cable terminal. Background Art

[0002] Cables are commonly used signal transmission tools in life. In industrial control and railway signal systems, in order to ensure the quality of signal transmission, cable protection and sealing are extremely important. If there are problems with the cable protection and sealing, it will not only affect the signal transmission quality, but in serious cases it may even endanger railway driving safety.

[0003] Between the existing cable branches and different conductive cores, since different branches are branched from one main line, there will be gaps between the branched branches. The gaps are usually exposed, which will cause interference to the cable signals and affect the signal transmission quality of the cable. In addition, pollutants will be stored in the gaps, which will corrode the cables and affect their service life.

[0004] After searching, a Chinese patent with publication number CN209692328U discloses a sealing sleeve for cable branching. The main finger sleeve and the branch finger sleeve of the utility model are arranged in an integral shape, and the sealing between the main finger sleeve and the branch finger sleeve is guaranteed. After heating the main finger sleeve and the branch finger sleeve, the gaps between each branch line can be sealed; when the heat shrink tube shrinks due to heat, the hot melt adhesive layer also melts due to heat, and the hot melt adhesive can be filled between each branch line to further enhance the sealing between the heat shrink tube and the cable; the anti-corrosion layer can enhance the corrosion resistance of the heat shrink tube to prevent pollutants from corroding and damaging the cable.

[0005] However, when the above-mentioned sealing sleeve is actually used, the cable branches need to be connected at different angles in actual application scenarios. At the same time, the cable may vibrate to a certain extent during use. At this time, the protective sealing of the finger sleeve on the cable branch is weakened to a certain extent, affecting the safe use of the cable. Utility Model Content
