Description

Technical Field

[0001] The utility model belongs to the technical field of multi-head cables, and more specifically, relates to a multi-head compression-resistant cable. Background Art

[0002] A multi-head cable is a cable that integrates multiple plugs or interfaces. Through a single input such as a power socket or power adapter, it can provide power or data transmission services to multiple devices at the same time. Therefore, it is widely used in scenarios such as home entertainment and office places. The existing multi-head cables are mainly composed of multiple groups of core wires. The outside of the core wires is wrapped with tin foil and outer sheath to prevent interference and provide protection. The plug is formed by pressing and riveting the terminals on one end of the multiple groups of core wires and clamping them inside the connector. The live wire in the core needs to be installed with a fuse to protect the circuit.

[0003] Existing application number CN201720512457.X This utility model relates to a pressure-resistant cable. The cable includes a hollow insulating tube body and a core wire passed through the insulating tube body for transmitting a medium. A pressure-resistant component is provided between the insulating tube body and the core wire to prevent the core wire from being crushed. The pressure-resistant component includes a thick-diameter tube fitted with the inner surface of the insulating tube body and a thin-diameter tube fitted with the outer surface of the core wire. A number of brackets are provided in the gap between the thin-diameter tube and the thick-diameter tube. Due to the presence of the thick-diameter tube, the thick-diameter tube can resist damage to the core wire by external forces. At the same time, due to the presence of the thin-diameter tube, the thin-diameter tube can resist damage to the core wire by external forces. Moreover, due to the cooperation of the thin-diameter tube, the bracket and the thick-diameter tube, they can resist damage to the core wire by external forces, thereby ensuring the reliability of the cable operation.

[0004] Based on the above, most existing multi-head cables use a rubber sleeve wrapped around the outside of the fuse for protection. The rubber sleeve has a poor pressure protection effect on the fuse, and it is inconvenient to replace the fuse. In addition, the joints of the multi-head cable mostly use a clip-on method to connect multiple groups of wire cores. The clip-on joint has a poor pressure protection effect and is prone to falling off when the joint is bent and compressed. Utility Model Content
