The integral casting technology enables the banana plug to be closely integrated with the plastic parts. The special-shaped sheath design + groove card slot design + anti-slip plug-in and pull-out design + waterproof vapor design solve the headache of reverse plug insertion and difficult plug-in and pull-out problems24K real gold plating, up to 2U thick, ensures stable current transmission; banana plug -slotted design, larger contact area, can withstand high currents of constant 45A and value of 90AThe female head has an anti-sparking resistor inside, and the shell is made of insulating material PA, with a flame retardant rating of UL94 V0Excellent material, , can be used for about 1000 hoursClear "+" and "-" markings to avoid errors.
