Abstract
The anti-flashover ring of the present invention includes a substantially cylindrical body having an outer surface with a plurality of passageways thereon. Each of the passageways pass from one of the sidewalls through the body to the other of the sidewalls of the ring. The passageways function to provide fluid communication between the atmosphere surrounding an accessory product such as a bushing insert and the interior of a connector mounted thereon when the connector is being pulled off the bushing insert. The fluid communication prevents a vacuum from forming between the connector and the bushing insert that can lead to a flashover between an electrical probe in the connector and a ground shield of the bushing insert. The anti-flashover ring is also configured to provide an indication to the operator installing the connector of when the connector is fully installed on the bushing insert. Such indication is provided by providing the ring with a width that is equal to length of the lip of the connector when the connector is fully installed. As such, the operator installing the connector continues to push on the connector until the end of the lip aligns with the end of the ring.
