(Main)Aerospace series - Terminal lugs and in-line splices for crimping on electric conductors - Part 007: Nickel plated aluminium terminal lugs for crimping on nickel plated aluminium cable for inch series studs - Product standard
General Information
- Abstract
This product defines the characteristics of nickel plated aluminium terminal lugs for crimped connection on
nickel plated aluminium conductors.
This terminal is delivered blocked with plastic cap and with factory installed O'ring and the barrel internal part
is coated with a special grease which should not be removed before crimping on cable.
This European Standard should be used in conjunction with EN 3373-001.

Overview
EN 3373-007:2012 is a CEN product standard in the Aerospace series that specifies the characteristics of nickel plated aluminium terminal lugs intended for crimped connections on nickel plated aluminium conductors for inch series studs. The standard defines material, operating temperature, key dimensional and mass requirements, factory-installed features (plastic dust cap, O‑ring, internal special grease) and identifies how this product standard must be used together with the EN 3373 family (notably EN 3373-001).
Key topics and technical requirements
- Scope and material
- Applies to nickel plated aluminium terminal lugs for crimping on nickel plated aluminium cable for inch studs.
- Base material: aluminium alloy; plating: nickel.
- Operating temperature range: −65 °C to 150 °C.
- Factory preparation
- Terminals are delivered blocked with a plastic dust cap and with a factory installed O‑ring.
- Barrel internal part is coated with a special grease - this grease must not be removed prior to crimping.
- Dimensions and masses
- Mandatory external and internal dimensions and masses are given in Tables 1 and 2 (see standard). Dimensions/tolerances are in millimetres.
- Thread sizes, internal diameters (unplated), and mass references are defined per cable size.
- Example designation format: EN3373-007-602 (standard number + item code).
- Crimping and tooling
- Punch/die configurations, stripping lengths and crimp parameters for strand crimping are specified.
- Insulation support crimping uses a hexagonal die form; two identical dies required.
- Marking and packaging
- Marking: conductor AWG range and manufacturer’s monogram per EN 2424 (style F), embossed in the designated area.
- Packaging must be marked with EN designation, manufacturer name, part number, manufacturing date and batch number.
- Quality and tests
- Quality assurance, test methods and acceptance criteria are handled in accordance with EN 3373-001.
Applications and users
- Primary users: aerospace OEMs, electrical harness manufacturers, procurement and quality engineers, maintenance organizations and suppliers of aircraft electrical components.
- Typical applications:
- Aircraft wiring harnesses and electrical distribution systems using nickel plated aluminium conductors and inch-series studs.
- Repair and replacement of crimped terminations where consistent dimensional, environmental and mechanical performance is required.
- Benefits:
- Ensures compatibility across suppliers, repeatable crimp performance, and traceable marking/packaging for aerospace quality systems.
