As shown in fig. 1-5, the utility model discloses a high sealed plastic connects, including connecting main part 1, connect 1 one side threaded connection of main part to have lock nut 2, the opposite side that connects main part 1 is equipped with clamping sleeve 3, the lower part of clamping sleeve 3 is equipped with hexagonal abaculus 301, connect be equipped with in main part 1 with the embedded groove 101 that abaculus 301 is corresponding, 3 outsides of clamping sleeve are equipped with compels tight head 4, compel tight head 4 with connect 1 surface threaded connection of main part. The inner diameter of the clamping sleeve 3 is adapted to the diameter of the cable, i.e. the cable can fit exactly into the clamping sleeve 3. In order to facilitate the passage of the cable, the inner diameter of the connector body 1 is greater than the inner diameter of the clamping sleeve 3. For the convenience of connection and positioning, a regular polygonal ring is convexly arranged in the middle of the joint body 1.

The outer surface of the protected clamping sleeve 3 is provided with anti-skid threads 302. The anti-slip threads 302 facilitate the rotational fitting of a cable into the clamping sleeve 3. As shown in fig. 3-4, the lower portion of the clamping sleeve 3 is further provided with a circular blocking piece, the bottom of the circular blocking piece is connected with the insert 301, a groove for accommodating the circular blocking piece is also formed inside the connector body 1, the diameter of the circular blocking piece is larger than that of the insert 301, and the round blocking piece is used for preventing water, dust and the like from entering the insert 301 to further protect the cable, and in the scheme, the clamping sleeve 3 is integrally formed.

A gasket 5 is arranged between the locking nut 2 and the joint main body 1. Gasket 5 is the ring shape, comprises the rubber material, works as lock nut 2 can extrude when screwing up gasket 5 makes 5 atress extrusion deformation of gasket to this plugs up lock nut 2 with connect the space between the main part 1, improve the leakproofness.

As shown in fig. 5 in particular, the face of the lock nut 2 close to the washer 5 is provided with a protruding thread 201. The thread 201 and the lock nut 2 are integrally formed. The cross section of the locking nut 2 is in a regular hexagon shape, and in order to facilitate the rotation of the locking nut 2, transition arcs are arranged between adjacent edges of the regular hexagon.
