Description
Technical Field
The utility model relates to an electronic product field, concretely relates to equipotential electrode assembly.
Background
In some water-cooled electrical products, deionized water is adopted for cooling, and because the deionized water is not an absolute insulator, weak leakage current can be generated in the water, so that partial parts of the electrical products are locally and severely corroded; the reasonable arrangement of the water electrodes can effectively perform equipotential treatment on the deionized water, avoid the corrosion of important parts and ensure the safe and reliable operation of products.
The water electrodes used on the existing plastic water pipes are mainly divided into two types: fabricated and injection molded. The assembled water electrode has the advantage of good sealing performance, but has the disadvantages of high cost, complex installation and more required materials; although the injection molding type water electrode has low cost and convenient installation, the water leakage risk exists because the metal piece and the plastic piece have different heat shrinkage rates.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an avoid the equipotential electrode assembly of the defect of leaking that injection molding process brought.
The technical scheme of the utility model is that: the utility model provides an equipotential electrode assembly, including electrically conductive contact pin, insulating overcoat, seal assembly includes threaded connection's first linkage segment and second linkage segment, the tail end of electrically conductive contact pin is the T style of calligraphy, the tail end of first linkage segment is equipped with external screw thread connecting portion, the head end of second linkage segment corresponds external screw thread connecting portion and is provided with female screw thread connecting portion, be equipped with the jack that the axial was arranged in the first linkage segment, the jack matches with the tail end shape of electrically conductive contact pin, the tail end setting of electrically conductive contact pin is in the jack, be provided with support piece between the terminal surface of the female screw thread connecting portion of electrically conductive contact pin and second linkage segment, the head end of first linkage segment is equipped with inside sunken sealing washer recess, the cladding is in seal assembly's periphery.
According to the further technical scheme, an O-shaped sealing ring is embedded between the sealing ring groove of the first connecting section and the outer ring of the conductive contact pin.
According to a further technical scheme, the outer ring of the insulating outer sleeve is provided with an external thread used for connecting a water pipe joint.
Further technical scheme, the periphery of the external screw thread tip of insulating overcoat is provided with sealed recess.
The utility model has the advantages that:
the utility model discloses a set up seal assembly between insulating overcoat and electrically conductive contact pin, ensured the leakproofness between electrically conductive contact pin and the insulating overcoat, seal assembly has threaded connection's first linkage segment and second linkage segment to constitute, and the assembly is simple, is fit for mass production widely.
