AI Technical Summary
In traditional watertight connectors, the O-rings are prone to deformation and displacement, resulting in poor bonding between the pin conductor and the insulating material, decreased connector withstand voltage performance, increased size, and increased testing complexity and cost.
The pressure-dispersing components, which employ a threaded structure, are respectively opened on the wall of the connecting hole and the surface of the pin conductor. This changes the pressure transmission path, reduces direct impact on the pin conductor, and eliminates the need for O-rings to achieve a sealing effect, thus simplifying pressure testing.
It enhances the connector's pressure resistance, reduces its size and material costs, lowers manufacturing complexity, and enables pressure testing without the need for plugs.
