insulating housing 33 that does not go through the hole on the bottom of the housing 34 the insulating housing 33 has a hole on the bottom to let the wires 35 to go through to connect to the pcb 32 3 a refers to the distance between the edge of the hole on the bottom of the insulating housing and the edge of the hole on the bottom of the housing this distance has to satisfy the related electrical requirements such as the creepage distance fig4 a and 4b show a led round light the separator in this case is an insulating housing 43 installed between the pcb 42 and the housing 44 the wires 45 connect to the pcb 42 on the top of the insulating housing 43 there is no hole on the insulating housing for the wires fig5 a and 5b show a led round light the separator in this case is an insulating housing 53 installed between the pcb 52 and the housing 54 the insulating housing 53 goes through the hole on the side of the metal housing 54 the wires 55 connect to pcb 52 through the hole thus this configuration shows an example with one or more openings extending through the channel with one or more wires extending through the one or more openings and the separator is configured to conform to the interior surface of the one or more openings and separate the wires from the housing fig6 a and 6b show a led round light leds 61 are mounted on the pcb 62 the separator in this case is an insulating housing 63.
