Selecting Heavy-duty Connectors By Feel And Hardness

Step 3: Rely on Instinct.

A qualified 4 pin heavy duty connector power cord not only feels moderately elastic when plugging and unplugging each socket, but also feels the same throughout. A substandard 6 pin heavy duty connector power cord feels either too loose or too tight, has poor elasticity, and is prone to loosening. A substandard connector heavy duty power cord feels different; each socket is clearly visible.

Step 4: Check the stiffness

A qualified heavy duty 2 pin connector power cord feels soft to the touch and has a firm and reliable connection to a heavy duty connector 16 pin power supply. The power cord of a substandard heavy duty connector 5 pin is soft to the touch and the connection to the heavy duty connector 6 pin is not secure, making it easy to break.
