Example 1
As shown in fig. 1, the embodiment of the utility model discloses an anti-oxidation end post cap, which effectively prevents the end post of a storage battery from being oxidized and prolongs the service life of the storage battery.
Specifically, the anti-oxidation end post cap is applied to an end post of a storage battery and comprises a cap barrel 10 and a base 20. Wherein the cap barrel 10 is cylindrical, and the top end of the cap barrel is closed; the inner wall of the cap cylinder is provided with a sealing ring 11, and the sealing ring 11 is fixedly connected with the cap cylinder; when the anti-oxidation end post cap is fixed on the end post, the sealing ring is extruded with the end post, so that the inner cavity of the cap barrel forms a closed space; the base is arranged at the bottom of the cap barrel, and extends along the outward edge of the cap barrel; the base and the cap barrel are integrally formed.
As shown in fig. 2, the cap cylinder is cylindrical, and the top end of the cap cylinder is closed, so that water vapor, air and other substances cannot enter through the cap cylinder, and the oxidation speed of the end column is effectively slowed down. As shown in fig. 3, the sealing ring 11 is disposed on the inner wall of the cap cylinder 10, and the bottom surface of the sealing ring is not lower than the bottom surface of the base, so that the base can be stably supported and fixed on the end post when the anti-oxidation end post cap is mounted on the end post 30.
The seal ring 11 is made of an elastic material, and is typically a rubber seal ring, such as an O-ring rubber seal. And the SIL silicon rubber material or the perfluoro ether rubber sealing ring can be adopted as the material, so that the wear resistance and the air tightness are good. Through elastic material's sealing ring for when the oxidation prevention end post cap was established at the end post, closely connected with the end post, airtight effect is good. Meanwhile, in order to improve the sealing effect of the sealing ring, the diameter of the sealing ring is smaller than that of the end post. When the anti-oxidation end post cap is installed on the end post, the sealing ring is in interference fit with the end post, so that the sealing ring is tightly connected with the end post, and the terminal 31 at the upper end of the end post enters the cap barrel. The sealing ring is extruded with the end column, and the column body at the upper end of the end column is in interference fit with the sealing ring, so that the inner wall of the cap barrel, the end column and the sealing ring form a closed space, and moisture and oxygen are reduced in the use process of the end column.
Further, the diameter of the sealing ring is 0.2 mm-0.3 mm smaller than the diameter of the end post. The sealing ring needs to be tightly matched with the end post, if the diameter of the sealing ring is too small, the sealing ring is kept in an excessively tight state when sleeved on the end post, so that the service life of the sealing ring is reduced; if the diameter is too large, the air tightness effect is poor, and the end post still can be oxidized after long-term use. Therefore, in the utility model, the diameter of the sealing ring is smaller than the diameter of the end post by 0.25mm, so that the sealing ring is convenient to install and detach when the anti-oxidation end post cap is installed on the end post or in the process of detaching the anti-oxidation end post cap from the end post while ensuring the air tightness.
The sealing ring and the cap barrel can be fixedly connected or detachably connected. When the sealing ring is detachably connected with the cap barrel, the sealing ring is sleeved on the terminal of the end post, and then the cap barrel is fixed with the sealing ring; or the cap cylinder and the sealing ring are fixed first and then sleeved in the terminal of the end post. In the utility model, the sealing ring is directly fixed at the lower end of the cap barrel, the anti-oxidation end column cap is directly pressed, and the sealing ring is fixed at the end column of the storage battery, so that the storage battery is convenient to install or detach.
Generally, the taper of the traditional end column protective cap adopts 1:9, but if the ratio is directly used, a negative pressure environment is easily formed in the cap barrel due to the sealing ring arranged on the cap barrel, and the negative pressure environment is difficult to disassemble. Therefore, the taper of the oxidation preventing end cap is 1:9 to 9.6, preferably 1:9.5.+ -. 0.01 in the present utility model. Through selecting the taper, the airtight space in the cap barrel is prevented from forming a negative pressure environment, and the anti-oxidation end column cap is convenient to install and detach.
The top of the cap barrel is also provided with a top cover 12, and the top of the cap barrel is closed by the top cover, so that substances such as water vapor or oxygen are prevented from entering, and oxidation of the end column is effectively slowed down. In this embodiment, since the oxidation-preventing end cap is applied to the end post of the storage battery, in order to facilitate rapid determination of the polarity of the end post, the outer surface of the top cap is provided with a positive electrode sign 121 or a negative electrode sign. And an arrow mark is arranged on the top cover and used for indicating the opening and rotating direction of the anti-oxidation end column cap.
More, the outer wall of the oxidation preventing end cap barrel is also provided with at least two reinforcing ribs 13. The reinforcing ribs 13 extend along the top cover 12 of the cap barrel toward the base. As shown in fig. 2 and 4, in the utility model, 4 reinforcing ribs are arranged, and the reinforcing ribs are uniformly arranged on the outer wall of the cap barrel, so that the strength of the anti-oxidation end column cap is improved, and the damage of the anti-oxidation end column caused by stress in the process of disassembly or installation is avoided.
Example two
Based on the same inventive concept, the utility model also provides a storage battery, which comprises an end post and an anti-oxidation end post cap according to the first embodiment. Fig. 5 is a cross-sectional view taken along A-A in fig. 2 of the oxidation-preventing end cap mounted to the end post of the battery. The anti-oxidation end post cap is arranged on the end post of the storage battery, and a terminal on the end post enters the anti-oxidation end post cap. The anti-oxidation end post cap is arranged on an end post of the storage battery; the terminal of the end post enters the cap barrel of the anti-oxidation end post cap, and the sealing ring is extruded with the end post, so that the terminal in the cap barrel is positioned in a closed space. Oxygen and moisture in the air are difficult to enter, so that the oxidation speed of the terminal in the end post is effectively slowed down, and the service life of the storage battery is prolonged.
According to the anti-oxidation end post cap and the storage battery provided by the utility model, the top end of the cap barrel of the anti-oxidation end post cap is closed, the inner wall of the cap barrel is provided with the sealing ring, when the anti-oxidation end post cap is fixed on the end post, the sealing ring is extruded with the end post, so that the inner cavity of the cap barrel forms a closed space, moisture and oxygen are effectively blocked from contacting with the terminal of the end post through the sealing ring of the anti-oxidation end post cap, the terminal oxidation speed of the end post is slowed down, and the service lives of the end post and the storage battery are effectively prolonged.
