Description

Technical Field

[0001] The utility model relates to a power supply and signal connector male end used in the connector field. Background Art

[0002] Connectors are irreplaceable in the Internet field. More and more fields use connectors that have both power and signals. Heat dissipation has always been an eternal problem for power connectors.
