摘要： A connection mechanism for connecting and disconnecting a cable connector to a bushing mounted on an electrical apparatus which is easier to use than cable connectors which require the threading of one electrical contact into another and which require more than one person to operate the connection mechanism. The connection mechanism assists in properly aligning the cable connector and the bushing and securely connects the cable connector to the bushing. Further, this connection mechanism eliminates the problem present in prior connection mechanisms of having to supply significant force in order to break the rubber-to-rubber interface bond which can occur when the connector has been connected to the bushing for a substantial period of time.
