Problems solved by technology
With the gradual development of the world economy, the expansion and new construction of various industries are constantly increasing, and the technology of various precision instruments, industrial and mining equipment, mechanical equipment, complete sets of equipment, and processing equipment is constantly improving; the original equipment power supply Connecting plug-ins can no longer adapt to the high-precision and safe operation of equipment. Good electrical conductivity and safe and reliable connecting devices will be the safety guarantee of the power connection system
[0003] At present, the waterproof performance of the existing common IEC309 industrial plugs and sockets is not very good, and they will break when exposed to water. The application places are limited and the range is limited, which is very inconvenient.
Improper use will cause serious damage to life and property

The invention discloses a plug waterproof structure which comprises a plug shell, a wire rod and a rear cover. The wire rod penetrates out of the tail end of the plug shell, a wire clamp and a waterproof rubber ring are annularly arranged between the plug shell and the wire rod in sequence, a through hole where the wire rod penetrates is formed in the center of the rear cover, a return clamp hollow sleeve matched with the wire rod is arranged inward at the position of the through hole, the end portion of the return clamp hollow sleeve is in seal connection with the waterproof rubber ring and the wire clamp in a squeezing mode, an external thread structure is arranged on the tail portion of the plug shell, and an internal thread structure matched with the external thread structure is arranged in the rear cover. The plug waterproof structure is used for an IEC309IP67 plug, achieves the good waterproof effect through interference assembly of the rear cover, the wire clamp and the water proof rubber ring, has the good waterproof function, cannot be limited by using places, can be safely used due to the fact that the plug waterproof structure can prevent water, and ensures the safety of life property of the user.
Description
