Overview - EN 3645-007:2015 (Protective cover for plug)
EN 3645-007:2015 is a European product standard from CEN for protective covers for plugs used with aerospace circular electrical connectors featuring a triple-start threaded coupling. The standard defines required characteristics, designation and marking, dimensions and mass, materials and surface treatments, and attachment types for plug protective covers compatible with shell sizes 09–25. These connectors are derived from and interchangeable with models W, F, K and Z in MIL‑DTL‑38999/32 and are intended for continuous operating temperatures of 175 °C or 200 °C.
Key topics and technical requirements
- Scope and compatibility
- Applies to models listed in Table 2 (models W, F, K, Z) and shell sizes coded A–J (sizes 09–25).
- Interchangeability with MIL‑DTL‑38999/32 series III metric designs is specified.
- Dimensions and mass
- Detailed dimensional data, tolerances and mass are given in Figure 1 and Table 1 (dimensions in millimetres).
- Example detail: eyelet hole diameter specified as 4.24 mm −0.13 mm; sealing gasket shall be bonded or mechanically retained.
- Materials and surface treatments
- Model-dependent construction and finish are specified in Table 2:
- W: cadmium‑plated aluminium alloy, olive green, salt spray resistance 500 h, max 175 °C
- F: nickel‑plated aluminium alloy, max 200 °C
- K: stainless steel, max 200 °C
- Z: zinc‑nickel plated aluminium, non‑reflective black, max 175 °C
- Model-dependent construction and finish are specified in Table 2:
- Attachment and sealing
- Attachment types in Table 4 (stainless steel chain, stainless steel rope with PTFE jacket, ring or eyelet).
- Fastener materials and freedom of chain/rope rotation specified.
- Electrical, mechanical and climatic performance
- Performance characteristics are referenced to EN 3645-002 and EN 3645-001 (technical specification).
- Designation and marking
- Standardised designation format (example: PROTECTIVE COVER ELECTRICAL CONNECTOR EN3645‑F4B7) and marking requirements per EN 3645-001.
Applications and users
- Practical applications:
- Protective covers for plugs on aerospace and defence electrical systems where high-temperature and corrosion resistance are required.
- Used during storage, maintenance, transport or when connectors are disconnected to protect contacts from contamination and mechanical damage.
- Primary users:
- Aerospace OEMs, connector and accessory manufacturers, systems and avionics designers, procurement and quality assurance teams, and maintenance organizations requiring standard-compliant components.
