Abstract
A valve control sealed lead-acid storage battery terminal sealing structure comprises a battery cover, a lead bushing, a pole, a bus bar, a copper terminal, an O-shaped sealing ring and a protection ring, wherein the lead bushing and the O-shaped sealing ring are pressed in the battery cover, the lead bushing and the pole are welded into a whole, and epoxy resin is filled between the protection ring and the lead bushing as well as between the protection ring and the pole for secondary sealing. The utility model discloses have sufficient intensity, can bear the produced power of polar plate deformation, lead bush and upper cover faying face increase, have prolonged the acid-climbing distance, and welding and veneer are sealed twice in addition, can effectively prevent acid leakage, and extension battery life avoids environmental pollution.
Description
The utility model relates to a kind of terminal sealing structure, especially for the terminal sealing structure of valve-control sealed lead acid battery.
Terminal sealing structure is the important component part of valve-control sealed lead acid battery, in order to guarantee battery in the course of the work the anacidity hydrorrhea go out, bear the power that the pole plate distortion is produced in the battery charge and discharge process.By bolt be connected copper bar or the line that is flexible coupling links to each other conduction current with ancillary equipment.Early stage terminal sealing structure is that terminal is directly inserted in the hole of battery cover, plastic sheath is glued in the terminal hole of battery cover again, adopts the epoxide-resin glue sealing.The power that is produced when moment of torsion when this structure connects bolt and pole plate distortion is born by glue and pole itself fully, and glue-line is cracked, the ageing-resistant performance of glue is relatively poor in addition, can produce Lou acid, climb sour phenomenon, causes that battery is dry, influence useful life, also bring environmental pollution.
The purpose of this utility model is to provide a kind of can bear the power that the pole plate distortion is produced in the battery charge and discharge process, assurance battery anacidity hydrorrhea in the course of the work goes out, prolong battery useful life, avoid the Valve Controlled Sealed Lead-acid Battery Connector Hermetically-sealed Construction of environmental pollution.
The technical solution of the utility model is that the sealing structure comprises battery cover, lead bushing, pole, bus-bar, copper tip, O RunddichtringO, guard ring, improvements are that lead bushing and O RunddichtringO adopt high-pressure injection moulding method to be compressed in the battery cover, and lead bushing and pole are integrally welded.
Filling epoxy resin glue between above-mentioned guard ring and lead bushing, the pole, the lead bushing outside is zigzag or labyrinth shape, and copper tip is embedded in the pole, and pole and bus-bar fuse.
Adopt technique scheme, because lead bushing becomes to closely cooperate with O-ring seals, pole and lead bushing are integrally welded, have enough intensity, can bear the power that the pole plate distortion is produced.The lead bushing outside is zigzag or labyrinth shape, has increased in conjunction with the face length degree, has prolonged and has climbed sour distance, can effectively prevent the acid solution seepage.Pole and lead bushing adopt soldering or gas welding mode to fuse together, and between lead bushing and guard ring, adopt epoxide-resin glue to carry out secondary seal, pole is linked to be with loam cake, lead bushing, prevent that the pole plate distortion from making seal break-off, cause Lou acid to cause that battery is dry, thereby can prolong battery useful life, avoid environmental pollution.
Further specify the utility model below in conjunction with drawings and Examples.
Accompanying drawing is the utility model structural representation.
