Abstract
The invention relates to the field of electric connectors, and particularly relates to a virtual connection preventing short circuit connector assembly. A short circuit socket of the virtual connection preventing short circuit assembly comprises a shell component and more than two contact pieces arranged on the shell component, each contact piece comprises a contact and a tail contact piece which are arranged in front and back positions, the rear end of each contact is provided with a floating spring in an abutting mode and is disconnected with the corresponding tail contact piece at an initial state under the action of the floating spring, and each of the contacts is assembled on the shell component in a mode of being relatively independent in action. In the using process, when contacts of the short circuit socket are matched with a conductive plane of a plug, the relatively long contact can further compress the floating spring after being contacted with the conductive plane until the relatively short contact is reliably contacted with the conductive plane, thereby being capable of avoiding adverse effects imposed on the connection reliability by machining tolerance of the connector, and solving a problem of poor contact caused by the processing tolerance of an existing short circuit connector.
