Abstract

Arcing, electrical noise, and other disturbances are prevented when electrically connecting lines through a connector with live power present. An electrical connector includes a male plug 1 for mating with a female plug 2. A DC power supply 3 is connected through a switch 4 across lines 5 and 6, which have a capacitor 7 of large capacitance therebetween. The lines 5 and 6 are connected to pins 8 and 9, respectively, of the male plug 1. The pins 8 and 9 extend further from the male plug 1 than pins 10, 11, 12, and 13. The pin 8 mates with a pin 14 in the female plug 2, and the pin 9 mates with a pin 15 in the female plug 2. A capacitor 16, which is of a large capacitance, extends between the lines 14 and 15 as does a load 17.

Non-Arcing Connector

Arcing, electrical noise, and other disturbances are prevented when electrically connecting lines through a connector with live power present. An electrical connector includes a male plug 1 for mating with a female plug 2. A DC power supply 3 is connected through a switch 4 across lines 5 and 6, which have a capacitor 7 of large capacitance therebetween. The lines 5 and 6 are connected to pins 8 and 9, respectively, of the male plug 1. The pins 8 and 9 extend further from the male plug 1 than pins 10, 11, 12, and 13. The pin 8 mates with a pin 14 in the female plug 2, and the pin 9 mates with a pin 15 in the female plug 2. A capacitor 16, which is of a large capacitance, extends between the lines 14 and 15 as does a load 17. When the plug 1 is connected to the plug 2, a resistor 18 in the line 5 substantially reduces the current flowing from the capacitor 7 through the pin 8 to the pin 14 and from the pin 15 to the pin 9 to prevent arcing therebetween. Without the resistor 18, which has a resistance at least an order of magnitude greater than the resistance of the wiring, arcing would occur between the pins 8 and 14 and the pins 9 and 15 because of the large transient current produced by the charge stored in the capacitor 7 since the only limiting action on the magnitude of the current would be by the DC resistance of the circuit and the effective series resistance of the capacitors 7 and 16. By the time that the pins 10-13 mate with pins 19-...
