What is a spiral cable 7-PIN?
In this lighting term, we discuss a unique cable and, to be precise, the Spiral Cable 7-PIN.
A spiral cable (also known as a curly cord) is a cable characterised by its flexibility. The coiled cable is elastic and thus provides greater freedom of movement with the connected device, without the cable having to be longer. A coiled cable also prevents tangling. The cable can extend in three- to fourfold lengths and consists of current-carrying copper wires and associated insulation. The outer insulation is often a PUR cable. Pur cables, unlike PVC cables, are more expensive but more robust and durable. PVC cables lose flexibility/resilience due to continuous loading.
Spiral cable 7-PIN
In the lighting industry, the spiral cable with a 7-PIN connection is sometimes used. The cable is a 'normal' spiral cable with a 7-PIN connection. The cable can be useful when connecting towing objects such as old semi-trailers, bike carriers, boat semi-trailers or horse semi-trailers. Trucks also sometimes use a spiral cable to make a connection to their semi-trailer. If you have a 13-PIN connection but still have a 7-PIN spiral cable, you will need to use an adapter cable. This will make the 7-pin connection fit the 13-PIN junction box.
