Abstract
A kind of storage battery high reliability end post sealing structure, including battery cap and copper core terminal, copper core terminal is located on lead seat, RTV silicone rubber seals layer and ethylene-propylene-diene monomer cushion rubber are set gradually between lead seat and battery cap, RTV silicone rubber seal layer uniform folds are fitted on the outside of RTV silicone rubber seals layer in the truncated cone-shaped surface of lead seat, the matching of ethylene-propylene-diene monomer cushion rubber.The utility model is multi-sealed using fluid sealant, gasket, copper nut and epoxy resin layer.The sealing structure mechanical resistant active force is strong, can effectively bear the impact of battery external force opposite end pole during installation and use, and because positive plate swells the extruding to positive terminal pole in charge and discharge process, improves the stability of end pole.On probation to show, the utility model, which can effectively suppress storage battery, to be occurred climbing sour phenomenon in long-term use, improves the reliability and security of storage battery.
Description
Technical field
A kind of storage battery is the utility model is related to, particularly storage battery high reliability end post sealing structure.
Background technology
Lead-acid accumulator is because its self discharge is small, high temperature performance is superior, the advantage such as cheap is still in the world at present
One of electrical source of power that yield is maximum, purposes is most wide.And the terminal sealing problem of valve-regulated lead-acid battery is many electric power storages of puzzlement
One major issue of pond producer.The terminal sealing performance of valve-regulated lead-acid battery is bad, lead-acid accumulator in long-term floating charge and
During high power discharge, it may appear that terminal climbs sour phenomenon, causes storage battery leakage, forms many security risks.Existing end pole is close
Seal structure is to set sealing ring between battery cap and end pole, terminal upper portion casting epoxy resin is then wrapped around, to reach
Sealing effect.This universal architecture, during storage battery long-time service, electrolyte is easily spread along lead terminal post, climbs to copper
Core corrodes terminal and causes battery leakage.In addition, epoxy resin is easily leak into storage battery because O-ring seal placement is not in place
Portion, influences storage battery performance.
Utility model content
The purpose of this utility model is that the drawback for the prior art, there is provided one kind can effectively solve accumulator terminal and climb
The storage battery of sour phenomenon high reliability end post sealing structure.
Problem described in the utility model with following technical proposals by being realized：
A kind of storage battery high reliability end post sealing structure, including battery cap and copper core terminal, copper core terminal position
In on lead seat, setting gradually RTV silicone rubber seals layer and ethylene-propylene-diene monomer cushion rubber, RTV silicon rubber between lead seat and battery cap
Sealant uniform fold is fitted on the outside of RTV silicone rubber seals layer in the truncated cone-shaped surface of lead seat, the matching of ethylene-propylene-diene monomer cushion rubber.
Above-mentioned storage battery high reliability end post sealing structure, the copper core terminal middle part screw copper nut, copper nut
Bottom surface compresses battery cap.
Above-mentioned storage battery high reliability end post sealing structure, is equipped with epoxy resin between battery cap and copper core terminal
Sealant, epoxy resin sealant is by the periphery of copper nut and top seal.
Above-mentioned storage battery high reliability end post sealing structure, the RTV silicone rubber seals layer thickness are 3-5 millimeters.
The utility model is climbed sour phenomenon opposite end post sealing structure and is improved for terminal is solved, using fluid sealant,
Gasket, copper nut and epoxy resin layer are multi-sealed.The sealing structure mechanical resistant active force is strong, can effectively bear battery and pacify
The impact of external force opposite end pole during dress and use, and positive terminal pole is squeezed because positive plate swells in charge and discharge process
Pressure, improves the stability of end pole.On probation to show, the utility model can effectively suppress storage battery and climb in long-term use
Sour phenomenon, improves the reliability and security of storage battery.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the partial enlarged view at A in Fig. 1.
In figure respectively marked as：1st, ethylene-propylene-diene monomer cushion rubber, 2, RTV silicone rubber seal layers, 3, battery cap, 4, copper core end
Son, 5, epoxy resin sealant, 6, copper nut, 7, lead seat.
Embodiment
Referring to Fig. 1, Fig. 2, the utility model includes battery cap 3, the lead seat 7 being arranged on storage battery and at lead seat
Copper core terminal 4.To prevent terminal from climbing sour phenomenon, the utility model is provided with multiple-sealed.First sealing positioned at lead seat with
Between battery cap, RTV silicone rubber seals layer 2 and ethylene-propylene-diene monomer cushion rubber 1, RTV silicon are equipped between lead seat and battery cap
Rubber sealant uniform fold is fitted in RTV silicone rubber seal layers in the truncated cone-shaped surface of lead seat, the matching of ethylene-propylene-diene monomer cushion rubber
Outside.RTV silicone rubber seals layer thickness is 3-5 millimeters.To make battery cap compress lead seat, the reliable of first of sealing is improved
Property, external screw thread and copper nut are set on copper core terminal, screw copper nut 6, copper nut bottom surface is compressed battery cap.Second
Sealed set epoxy resin sealant 5, is sealed copper nut periphery and top and the gap of battery cap by epoxy resin sealant
Close.
RTV silicon rubber first will be uniformly applied on lead seat by the utility model when making, and form the RTV silicon of thickness 3-5mm
Rubber sealant, then by ethylene propylene diene rubber snare on the outside of RTV silicone rubber seal layers, forms first of sealing；In 5 minutes
Buckle battery cap, then along copper core terminal screw thread rotation copper nut to tightening；After the curing of RTV silicone rubber seals layer,
Secondary seal is carried out using epoxy resin between copper core terminal and battery cap, forms epoxy resin sealant.
