Problems solved by technology

Because the metal insert of the existing plug is directly exposed, the metal insert is charged during the plug-in process. Since the finger is very close to the metal insert, once the finger slips at this time, it will cause electric shock, which is very dangerous.

Abstract

The invention relates to a spring plug comprising an insulating handle and metal inserting sheets which are installed on the insulating handle. The front end surface of the insulating handle is provided with a settlement groove. The metal inserting sheets are fixedly installed on the bottom wall of the settlement groove. The external part of the metal inserting sheets is provided with a first insulating cylinder. The external wall of the bottom end of the first insulating cylinder is fixedly provided with a slide block. The internal wall of the settlement groove is provided with a slide groove which slides with the aforementioned slide block in a matching way, and the slide block is limited in the slide groove. The internal wall of the first insulating cylinder is fixedly connected with a transverse beam, and a compression spring is connected between the transverse beam and the bottom wall of the settlement groove. Electric shock can be effectively avoided, and the spring plug is simple in whole structure and convenient to use.

Description

technical field [0001] The invention relates to a spring plug. Background technique [0002] The plug is used to electrically connect the electrical appliance and the socket. The plug generally includes an insulating handle and two or three metal inserts arranged at intervals. The rear end of the metal insert is connected to the electrical appliance. The front end of the socket is inserted into the socket, so as to realize the conduction. Because the metal insert of the existing plug is directly exposed, the metal insert is charged during the plugging process. Since the finger is very close to the metal insert, once the finger slips at this time, it will cause electric shock, which is very dangerous. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a spring plug, which can not only effectively avoid electric shock, but also has a simple overall structure and is easy to use. [0004] In order to solve the above-m...
