Description

Technical Field

[0001] The utility model relates to the technical field of connecting wires, in particular to a DC connecting wire with a winding function. Background Art

[0002] DC cables are conductors for transmitting direct current. DC cables can transfer AC / DC current from a switching power supply or transformer to other places, such as LCD monitors, surveillance cameras, laptops, and device controller power supplies. DC cables are currently widely used in digital products and small household appliances.

[0003] Application No. CN202120103736.7 introduces a DC connecting line that is easy to store. When coiled and stored, the wire clamping block located on the outer circle abuts against the clamping block located on the inner circle; along the coiling direction, the clamping block of the inner circle is located in front of the wire clamping block of the outer circle. The fan-shaped wire clamping block design allows the connecting line to be stored in a ring shape, and can be stored in a smaller shape under a limited bending radius. The clamping notches on both sides of the wire clamping block allow the connecting lines of the inner and outer circles to be connected at the same time. At the same time, the mutual squeezing of the two adjacent wire clamping blocks can effectively resist the rebound force of the connecting line. However, the storage structure of the connecting line is large in size, not easy to disassemble, and relatively inconvenient to use. Utility Model Content
