Description
Overview
A two-piece 6.3 mm connector for vehicle and equipment harnesses, sold as a mated male and female pair that push together as a butt joint. It is offered in two wire classes, 2.5 mm2 carrying 25A and 4 mm2 carrying 40A.
Specifications
- Series: DJ7021-6.3-11/21
- Terminal size: 6.3 mm
- Configuration: male and female pair, butt joint
- Variant 1: 13 AWG, 2.5 mm2, 25A
- Variant 2: 11 AWG, 4 mm2, 40A
- Intended wiring: vehicle and high-current equipment harnesses
Purpose
It puts a pluggable joint in a heavy current run where a soldered splice would be permanent, so a harness can be split for service. The 40A build exists for loads that would cook the 25A contacts.
Applications
- Automotive harness repairs
- Electric vehicle accessory wiring
- Battery and ground leads
- Pump, fan and winch feeds
- Trailer and tow wiring
- Equipment power distribution
How to Use
- Choose the variant from the load: 25A for 2.5 mm2, 40A for 4 mm2.
- Strip each wire to the crimp barrel length, matching gauge to variant.
- Crimp with a proper tool and pull-test every joint.
- Push the male and female halves together until they seat fully.
- Caution: stay inside the 25A or 40A rating of the part you ordered, and keep these low-voltage DC connectors off mains circuits.
