Abstract
The utility model relates to a protection device of a steel wire screw sleeve internally embedded in an aluminum alloy battery cover body. The protection device comprises the aluminum alloy battery cover body and the steel wire screw sleeve internally embedded in the aluminum alloy battery cover body and is characterized in that a stainless steel screw is connected onto the end surface of the steel wire screw sleeve in a sealed way. The head part inner surface of the screws fixed in the steel wire screw sleeve forms the sealed connection with the end surface of the steel wire screw sleeve through a polytetrafluoroethylene sealing pad, when the aluminum alloy battery cover body with the internally embedded steel wire screw sleeve is cleaned by an acid and base corrosion method for removing the surface oxidation layers, corrosive liquid is prevented from entering a threaded hole with the internally embedded steel wire screw sleeve, the connection intensity between the screw wire screw sleeve and the battery cover body is ensured, and the battery reliability is greatly improved. A protection ring is adopted, and the moving of the sealing pad is limited, so the steel wire screw sleeve can only upwards and downwards move, the sealing connection between the head part inner surface of the screw and the end surface of the steel wire screw sleeve is reinforced, and acid and base corrosive liquid is effectively prevented from entering the steel wire screw sleeve.
Description
Technical field
The utility model belongs to the battery cover technical field, especially relates to a kind of protective device that is embedded in steel-wire screw-socket in the aluminium alloy battery lid.
Background technology
Adopt at present mostly aluminum alloy materials as the battery lid, for making things convenient for being connected of battery and power device, common on the battery lid the embedded steel-wire screw-socket that is threaded the hole.Before the aluminium alloy battery covers welding, use acid, when caustic corrosion method cleaning and removing is removed surface oxide layer, cause corrosion, weakened the bonding strength of steel-wire screw-socket and battery lid steel-wire screw-socket owing to acid, alkali get into steel-wire screw-socket.
Summary of the invention
The utility model provides a kind of acid, caustic corrosion property liquid of effectively preventing to get in the steel-wire screw-socket of battery lid for solving the technical problem that exists in the known technology, guarantees the protective device that is embedded in steel-wire screw-socket in the aluminium alloy battery lid of steel-wire screw-socket and battery lid bonding strength.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of protective device that is embedded in steel-wire screw-socket in the aluminium alloy battery lid comprises aluminium alloy battery lid and is embedded in the steel-wire screw-socket in the battery lid, is characterized in: be sealedly connected with stainless steel screw on the end face of said steel-wire screw-socket.
The utility model can also adopt following technical characterictic:
Be equipped with polytetrafluoroethylene sealing gasket between the head of said screw and the battery lid.
Said polytetrafluoroethylene sealing gasket periphery is with the polytetrafluoroethylene guard ring.
Advantage and the good effect that the utlity model has are:
1, the utility model forms the end face of the head inner face that is fixed on screw in the steel-wire screw-socket and steel-wire screw-socket through polytetrafluoroethylene sealing gasket to be tightly connected; When having the aluminium alloy battery lid that is embedded with steel-wire screw-socket to carry out acid, caustic corrosion method cleaning and removing to remove surface oxide layer; Prevented that corrosive liquids from entering into the screwed hole the inside that is embedded with steel-wire screw-socket; Protected the integrality of steel-wire screw-socket and aluminium alloy battery lid contact-making surface; Guarantee the bonding strength of steel-wire screw-socket and battery lid, improved the reliability of battery greatly.
2, the utility model has moving of mobile polytetrafluoroethylmaterial material sealing gasket owing to adopt guard ring to limit; Make it can only be to moving up and down; Strengthened being tightly connected between the end face of head inner face and steel-wire screw-socket of screw, prevented that effectively acid, caustic corrosion property liquid from getting in the steel-wire screw-socket.
Description of drawings
Fig. 1 is a steel-wire screw-socket protective device half section sketch map in the utility model aluminium alloy battery lid.
Label among the figure is respectively: the 1-screw; The 2-sealing gasket; The 3-guard ring; 4-battery lid; The 5-steel-wire screw-socket.
Embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
With reference to accompanying drawing 1: a kind of protective device that is embedded in steel-wire screw-socket in the aluminium alloy battery lid comprises aluminium alloy battery lid and is embedded in the steel-wire screw-socket in the battery lid.
The innovative point of the utility model is: thread seal is connected with stainless steel screw in the said embedded steel-wire screw-socket; Be equipped with polytetrafluoroethylene sealing gasket between the head of said screw and the battery lid; Said polytetrafluoroethylene sealing gasket periphery is with the polytetrafluoroethylene guard ring.
The manufacturing process of the utility model:
Embodiment:
As shown in Figure 1; The aluminium alloy battery lid 4 that is embedded with steel-wire screw-socket 5 is being carried out acid, caustic corrosion method cleaning and removing except that before the surface oxide layer; The guard ring 3 of polytetrafluoroethylmaterial material is enclosed within on the sealing gasket 2 of polytetrafluoroethylmaterial material, and the sealing gasket of stainless steel screw 1 from guard ring passes, and screws in the steel-wire screw-socket; Moment with 0.6m.N is fastening, promptly processes the protective device that is embedded in steel-wire screw-socket in the aluminium alloy battery lid.
Operation principle: the sealing gasket of polytetrafluoroethylmaterial material has flowability; When screw is fastening; Guard ring has limited moving radially of sealing gasket; Can only be to moving up and down, make to form between the end face of head inner face and steel-wire screw-socket of screw to be tightly connected, prevented that effectively acid, caustic corrosion property liquid from getting in the steel-wire screw-socket.
The above is merely the preferred embodiment of the utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, can also make some distortion and improvement, this also should belong to the protection range of the utility model.
