Preferably, this cable seal structure also includes cable connector, and described cable connector is positioned at the upper end of transition urceolus, and cable connector is provided with perforation, and cable may pass through the perforation on cable connector.
Preferably, outside one layer of gum cover of parcel of described cable, sealing resin in the space in described gum cover, described resin combines with corresponding gum cover and cable core and is encapsulated by corresponding cable core.
Preferably, it is threaded connection between described transition urceolus and motor upper cover, and seals with the first sealing ring.It is threaded connection between described cable connector and transition urceolus, and seals with the second sealing ring.Further, it is additionally provided with elastic sealed clamping set between perforation and the described cable of described cable connector, thus reaching the effect of clamping cables and sealing.
As optimal technical scheme, described metallic conductor is made up of columned solid copper joint.
This utility model has the beneficial effect that
1, this utility model have employed multi-sealed protective measure, it is possible to ensures the sealing when cable of submersible motor is applied under water, has good water resistance and insulating properties.Wherein cable connector can play fixing cable, it is prevented that the effect that cable loosens；And transition urceolus provides another layer of protection, it is effectively ensured the sealing of device, and has been easily installed and dismantles.
2, this utility model utilizes metallic conductor to be isolated by two sections of cables, and the conductor in cable and metallic conductor are isolated by Insulating heat shrink, it is possible to play good insulating effect；By wrapping up one layer of gum cover, sealing resin in the space in gum cover, it is achieved the sealing to cable core in the outside of cable.Insulating properties and barrier propterty, the sealing property of Reliable guarantee cable are had concurrently.
