A standard Micro USB port is designed to accept a connector body that measures 6.85 mm by 1.8 mm (0.270 by 0.071 in). This dimension refers to the core metallic part of the connector that plugs into the port.
The reference provided states the dimensions for both Micro-A and Micro-B connectors, indicating they share the same foundational size for the part that interfaces with the port.
Understanding Micro USB Dimensions
When discussing the size of a Micro USB port, it's important to consider the dimensions of the connector designed to fit into it. The reference highlights two common Micro USB connector types: Micro-A and Micro-B.
- Core Connector Size: The most critical dimension for the port opening is the size of the connector body itself. According to the reference, both Micro-A and Micro-B connectors have a metallic body size of 6.85 mm wide by 1.8 mm tall. The port must accommodate these dimensions.
- Overmold Size: The reference also provides dimensions for the maximum "overmold boot size." This refers to the plastic casing around the metal connector part and potentially around the cable junction. While this doesn't define the port opening size, it indicates the physical space required around the port on a device to plug in the cable comfortably.
- Micro-A connector overmold: Up to 11.7 mm by 8.5 mm
- Micro-B connector overmold: Up to 10.6 mm by 8.5 mm
Micro USB Connector Sizes
Here is a summary of the key sizes mentioned in the reference:
| Characteristic | Dimension (mm) | Dimension (in) | Notes |
|---|---|---|---|
| Connector Body Size | 6.85 x 1.8 | 0.270 x 0.071 | Size that fits into the port; applies to both Micro-A and Micro-B |
| Micro-A Max Overmold Size | 11.7 x 8.5 | 0.46 x 0.33 | Maximum size of the plastic housing around the connector |
| Micro-B Max Overmold Size | 10.6 x 8.5 | 0.42 x 0.33 | Maximum size of the plastic housing around the connector |
The core size of the connector body, 6.85 mm by 1.8 mm, is the most direct answer to the size of the opening required for a Micro USB port.
