brief introduction
The special screw for connector is produced to solve the problems of poor sealing effect and unsmooth rotation of the central screw of the existing connector.
Structural principle
A central screw structure of a connector includes a central screw, a sealing gasket which fits with the shell is sheathed on the central screw rod, a first sealing ring is arranged on the sealing gasket at one end of the shell, a screw for tightening the sealing gasket on the shell is connected to the sealing gasket, a second sealing ring is arranged on the inner wall of the sealing gasket, and a sheath is set on the central screw rod, and both ends of the sheath are provided There is a gasket.
advantage
1. Through the first sealing ring and the second sealing ring arranged on the sealing gasket, the sealing problem of the rotating shaft of the central screw is solved. The external rainwater, sand dust and salt fog are blocked outside the shell, and the process of processing the sealing groove on the shell is avoided;
2. The sealing gasket on the sheath can effectively prevent the internal pouring glue from adhering to the central screw and affect the rotation;
3. The rain proof sealing grade of the central screw structure can reach ipx-7, and it can be soaked for 30min under water for 1m.
