Abstract
The invention discloses a sealed waterproof connector. The sealed waterproof connector comprises a socket, a plug and a tail accessory, wherein the plug is connected with the socket and the tail accessory. The sealed waterproof connector is characterized in that the socket comprises a disk protrusion used for being connected with an electrical device, a contact pin insulating sleeve and a contact pin, and the contact pin and the contact pin insulating sleeve are combined in a casting mode and arranged in the disk protrusion. The sealed waterproof connector is good in gas tightness, the plug is connected with the socket in a double-thread locking mode, and thus the sealed waterproof connector is firmer as a whole and higher in working stability. Therefore, the sealed waterproof connector has good sealing performance and good pressure resistance, and can be suitable for bad working conditions of coal mines, flood and the like.
