Housing and enclosure designs for the complete system.
|
|
|
|
## Purpose
|
|
This directory contains enclosure and housing designs that protect and contain the electronic and mechanical components. Enclosures may include multiple housings, covers, and panels depending on system complexity.
|
|
|
|
## Enclosure Types
|
|
Organize by enclosure function and hierarchy:
|
|
|
|
```
|
|

|
│ ├── top-cover.sldprt
|
|
│ ├── gaskets-seals.sldprt
|
|
│ └── housing-assembly.sldasm

## Design Considerations
|
|
|
|
### Environmental Protection
|
|
- **IP Rating**: Define ingress protection requirements
|
|
- **Sealing**: Gaskets, O-rings, and weatherproofing
|
|
- **Drainage**: Water management and condensation control
|
|
- **Ventilation**: Airflow and thermal management
|
|
|
|
### Mechanical Requirements
|
|
- **Structural Integrity**: Load bearing and impact resistance
|
|
- **Mounting**: Wall mount, panel mount, or free-standing
|
|
- **Access**: Service panels and component accessibility
|
|
- **Cable Management**: Entry points and strain relief
|
|
|
|
### Manufacturing Considerations
|
|
- **Material Selection**: Plastic, metal, composite materials
|
|
- **Manufacturing Process**: Injection molding, machining, sheet metal
|
|
- **Tolerances**: Fit and finish requirements
|
|
- **Surface Treatment**: Painting, anodizing, texturing
|
|
|
|
### Electrical Integration
|
|
- **EMI/RFI Shielding**: Electromagnetic compatibility
|
|
- **Grounding**: Electrical safety and noise reduction
|
|
- **Cable Entry**: Glands, connectors, and feedthroughs
|
|
- **Heat Dissipation**: Thermal interface to internal components
|
|
|
|
## File Organization
|
|
|
|
### Main Housing Files
|
|
- **Base/Bottom**: Primary structural component
|
|
- **Cover/Top**: Removable or hinged access
|
|
- **Sides/Walls**: Structural walls and mounting surfaces
|
|
- **Internal Structure**: Mounting posts, ribs, and supports
|
|
|
|
### Sub-Enclosure Files
|
|
- **Modular Housings**: Self-contained sub-assemblies
|
|
- **Protective Covers**: Component-specific protection
|
|
- **Interface Panels**: User interaction surfaces
|
|
- **Mounting Brackets**: Attachment to main housing
|
|
|
|
### Hardware and Fasteners
|
|
- **Screws and Bolts**: Fastening hardware specifications
|
|
- **Hinges and Latches**: Access mechanism components
|
|
- **Gaskets and Seals**: Environmental protection components
|
|
- **Inserts and Threads**: Threaded fastening points
|
|
|
|
## Material Specifications
|
|
Document material requirements for each component:
|
|
- **Mechanical Properties**: Strength, flexibility, durability
|
|
- **Environmental Resistance**: UV, chemical, temperature
|
|
- **Electrical Properties**: Conductivity, dielectric strength
|
|
- **Regulatory Compliance**: UL, CE, RoHS requirements
|
|
|
|
## Assembly Instructions
|
|
- **Assembly Sequence**: Order of component installation
|
|
- **Torque Specifications**: Fastener tightening requirements
|
|
- **Sealing Procedures**: Gasket installation and verification
|
|
- **Quality Checks**: Dimensional and functional verification
|
|
|
|
## Testing and Validation
|
|
- **Environmental Testing**: Temperature, humidity, vibration
|
|
- **Ingress Protection**: Water and dust resistance verification
|
|
- **EMC Testing**: Electromagnetic compatibility validation
|
|
- **Mechanical Testing**: Drop, impact, and load testing
