DC cables

 

I needed a 12V DC distribution and cables to various transceivers for my /P activities.  Since I would normally be using batteries all cables had to be fused and terminated with insulated connectors.

 

I recycled some neat mating DC connectors from end-of-life UPS systems.  I used heat shrink 'butt connectors' for connecting to 2.5mm2 and/or 4mm2 insulated wires, making a neat finish.  The end connectors are either 6.3mm female spade crimp connectors or 6.4mm ring crimp connectors, the latter matching the battery M6 bolt terminals.

 

 

I fitted an in-line waterproof fuse to a commercial DC distribution panel.

Detail of fuse and insulated ring connectors.  Wires are 2.5mm2.

Modified (fused) DC patch cables for my transceiver-to-battery connection.

In-line fuse and 6.4mm insulated ring connectors.  Wires are 4mm2.

In-line fuse and 6.3mm insulated female spade connectors.  Wires are 4mm2.

Cable with in-line fuse for Kenwood equipment.

Cable with in-line fuse and toroid ferrite for Yaesu equipment.

Special cable with split ends and ferrite clamp.  Note how the grey connectors mate.


 

 

The grey connectors are Anderson Power Products type SB (50A, 600V), total overkill for my /P transceiver set-up.  However they are fool-proof which is what you need working /P often under adverse weather conditions, you just want to click the mating connectors to safely power your transceiver.

 

 

These 10A-15A-20A fuses are used in automotive systems.

Insulated crimp connectors for 1.5-2.5mm2 wire.

Insulated crimp connectors for 4-6mm2 wire.


 

 

The above crimp connectors have a glue that melts (heat gun) and provides a watertight seal.
