Abstract
The utility model discloses a high-air-tightness pole sealing structure, which comprises a shell, poles and sealing rings; the end wall of the shell is provided with a through hole, the pole column is arranged in the through hole of the shell in a penetrating mode in a clearance mode, and a sealing ring is arranged between the pole column and the through hole of the shell. Because the utility model discloses a main spare part is only two, and spare part is less, and the structure is comparatively simple, and the structure after the improvement can realize with former equal function, has that degree of automation is high, production efficiency is high, the operability is good, stable quality's advantage, can realize mass production.
Description
Technical Field
The utility model relates to a battery structure especially relates to a high gas tightness utmost point post hole sealing structure.
Background
As shown in fig. 1, the conventional VCM connecting pole piece structure with corrosion resistance, leakage resistance and high air tightness includes: casing 1 ', utmost point post 2', first fluorine rubber packing ring 3 ', packing ring 4', second fluorine rubber packing ring 5 ', utmost point post lid 6', its casing assemblage realizes the function of product through processes such as riveting soon, pressure riveting, welding, because this traditional configuration and equipment spare part is more, spare part size is too little for production efficiency is low, the technology is complicated, difficult reality automated production.
Disclosure of Invention
An object of the utility model is to provide a simple structure's high gas tightness utmost point post hole sealing structure.
In order to achieve the above object, the technical solution of the present invention is:
the utility model relates to a high-air-tightness pole sealing structure, which comprises a shell, poles and sealing rings; the end wall of the shell is provided with a through hole, the pole column is arranged in the through hole of the shell in a penetrating mode in a clearance mode, and a sealing ring is arranged between the pole column and the through hole of the shell.
The utility model discloses a sealing structure, including utmost point post, sealing washer, the through-hole that the utmost point post middle part has a round annular recess, and the middle part of sealing washer has a vertical through hole that sets up, and the outer wall of sealing washer has annular narrow groove, and the recess cover in utmost point post middle part is put in the through-hole in sealing washer middle part, and the sealing washer has annular narrow groove card to be put on the through-hole wall of.
After the scheme is adopted, because the utility model discloses a casing, utmost point post, sealing washer, main spare part only two, and spare part is less, and the structure is comparatively simple, and the structure after the improvement can realize with former equal function, has that degree of automation is high, production efficiency is high, the operability is good, stable quality's advantage, can realize mass production.
The invention will be further described with reference to the accompanying drawings and specific embodiments.

Detailed Description
As shown in fig. 2-6, the utility model relates to a high gas tightness utmost point post hole sealing structure, including casing 1, utmost point post 2, sealing washer 3.
The end wall of the shell 1 is provided with a through hole 11, the pole 2 is arranged in the through hole 11 of the shell 1 in a clearance penetrating mode, and a sealing ring 3 is arranged between the pole 2 and the through hole 11 of the shell 1.
In this embodiment, the middle of the pole 2 has a ring-shaped groove 21, the middle of the sealing ring 3 has a longitudinally-arranged through hole 31, the outer wall of the sealing ring 3 has a ring-shaped narrow groove 32, the groove 21 in the middle of the pole 2 is sleeved in the through hole 31 in the middle of the sealing ring 3, and the ring-shaped narrow groove 32 of the sealing ring 3 is clamped on the wall of the through hole 11 of the housing 1.
The utility model discloses a production process:
the pole 2 and the shell 1 are automatically conveyed into a die through automatic equipment, fluororubber (sealing ring 3) is molded through an embedding method (INSERT MOLDING), the pole 2 and the shell 1 are molded into an assembly through the fluororubber and then conveyed into a spin riveting machine through automation again to complete the spin riveting process after automatic operation.
The above description is only a preferred embodiment of the present invention, and therefore the scope of the present invention should not be limited thereby, and all equivalent changes and modifications made within the scope of the claims and the specification should be considered within the scope of the present invention.
