Storage water heater is electronics positive pole for inner bag

The utility model discloses a storage water heater is electronics positive pole for inner bag who belongs to the storage water heater protection device field. This electron positive pole comprises the lead screw of corrosion resistant wire electrode, connection DC power supply positive wire and the insulator of lead screw and wire electrode junction parcel, wherein, wire electrode and lead screw adopt welding or threaded connection, mould plastics in the two joint department and wrap up the insulator that forms. The utility model discloses an increase the insulator in lead screw and wire electrode junction and seal insulation wrap, can effectively avoid electron positive pole other conducting material except that the wire electrode to contact with solution, avoid electron positive pole other metallic parts positions except that the wire electrode especially wire electrode and the emergence of lead screw junction dissolve fast, guaranteed electron anodal long -life and stability. 本实用新型公开了属于储水热水器保护装置领域的种储水热水器内胆
