Definition
A small fitting used to join two electrical wires end-to-end into a single continuous conductor. The connector grips the bare ends of both wires and is usually crimped, soldered, or both, then insulated to protect the joint from shorts, moisture, and vibration.
Plain English
A small sleeve that links two wires together so electricity can pass through them as if they were one wire.
Context Anchor
Seen during aircraft electrical repairs, wiring inspections, and maintenance on lights, radios, instruments, and other powered equipment.
Derivation
Splice comes from the Old Dutch splissen, meaning to join rope strands together. The same idea carried over to electrical work: joining two separate strands so they act as one.
Why Pilots Care
A properly installed splice connector prevents intermittent electrical failures in lights, instruments, and engine systems that could otherwise lead to in-flight malfunctions or emergency landings.
Analogy
Think of it as the electrical version of a hose coupler that joins two garden hoses so water keeps flowing without leaks or kinks.
Intuition Check
A splice connector is not just wires twisted together and covered. In aviation, it means an approved connection made by the proper maintenance method for that wire and aircraft.
Example Sentence 1
The mechanic used a splice connector to join the new landing light wire to the existing harness.
Example Sentence 2
During the annual inspection, each splice connector in the battery circuit was checked for proper crimp and insulation.
