1. Physical Appearance

Male Connector:
Features protruding, pin-like structures (e.g., blades, posts, or pins) designed to insert into a corresponding receptacle. Examples include power plugs with metal prongs or USB Type-A plugs.

Female Connector:
Contains recessed cavities, slots, or sockets to receive the male counterpart. Examples include power outlets with slots or USB Type-A ports.

2. Structural Characteristics

Male Connector:

Smooth exterior surfaces with exposed conductive pins/blades.

May include alignment pins or raised guides (e.g., in multi-pin connectors) to ensure proper orientation during mating.

Female Connector:

Internally equipped with spring-loaded contacts, elastic metal tabs, or clamping mechanisms to grip the male connector securely.

Example: A 3.5mm audio jack (female) contains spring contacts that engage with the male plug’s electrodes for signal transmission.

3. Labeling and Symbols

Male Connector:
Often marked with "Male," "M," or an arrow symbol (→) indicating the insertion direction.

Female Connector:
Typically labeled "Female," "F," or depicted with a hollow/circular symbol (○) representing the receptacle.

4. Industry-Specific Variations

In aerospace, automotive, or industrial applications:

Connectors may follow standards like MIL-SPEC, ISO, or SAE, with additional identifiers such as color coding (e.g., red for high-voltage female connectors).

Material choices (e.g., high-temperature thermoplastics for male pins) and sealing features (IP ratings) may further distinguish connectors.
