Description

Technical Field

[0001] The utility model relates to the technical field of cable splicing joints, in particular to a cable splicing joint. Background Art

[0002] Cable is a general term for optical cables, electrical cables and other items. Cables have many uses, mainly for controlling installation, connecting equipment, transmitting electricity and other multiple functions. They are common and indispensable in daily life. Because cables are charged, installation requires special care. When installing cables, they often need to be spliced ​​to achieve long-distance transmission.

[0003] In the prior art, when a cable splicing joint is used, the cable is usually clamped and connected, and insulation protection is performed at the joint. Since the cable is divided into two parts, a cable core and an insulating sleeve, the commonly used splicing joint is easily affected by external forces such as long-term pulling after the cable is spliced. In addition, the local clamping and splicing of the cable causes partial separation of the cable core or the insulating sleeve, which makes the cable prone to short circuits and exposure risks, reducing the stability of the cable splicing joint. Therefore, a cable splicing joint is needed. Utility Model Content
