Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, the battery 10 includes a battery cover 20 embedded with a terminal 21, the top of the terminal 21 is a cylindrical structure, and the top surface of the terminal 21 is provided with a threaded hole; as shown in fig. 2, the first screw portion 36 detachably connecting the battery terminal protection case 30 with the screw hole; the retaining ring 32 is arranged on the top surface of the first screw rod part 36 and exposed out of the threaded hole when in use, and the bottom surface of the retaining ring 32 is provided with a clamping groove 33 clamped with the outer side wall of the terminal 21 when in use.

As shown in fig. 3 and 4, the battery terminal protection sleeve 30 further includes a second screw portion 37 disposed on the top surface of the retaining ring 32, and the second screw portion 37 is provided with a nut 35 in a matching manner.

In order to facilitate the screwing of the first screw portion 36 into the threaded hole of the terminal 21, the nut 35 is suitably provided, and the first screw portion 36 and the second screw portion 37 are respectively provided for detachable connection with the threaded hole and the nut 35, and after the first screw portion 36 is screwed into the threaded hole, the inner wall of the clamping groove 33 of the retaining ring 32 needs to be clamped with the outer wall of the terminal 21, so that the retaining ring 32 should be arranged on the top surface of the first screw portion 36, the bottom surface of the second screw portion 37, and the opening of the clamping groove 33 faces the first screw portion 36.

A washer 34 is also included, the washer 34 being disposed on the second screw portion 37 between the retaining ring 32 and the nut 35.

In the process of forming the battery 10, the terminal 21 needs to be connected with the connecting piece, so the battery terminal protective sleeve 30 needs to fix the connecting piece, the nut 35 can rotate on the second screw part 37, so the connecting piece can be fixed between the nut 35 and the retaining ring 32, however, if the connecting piece is directly fixed between the nut 35 and the retaining ring 32, the retaining ring 32 is worn, and the protective effect of the retaining ring 32 on the terminal 21 is affected after the retaining ring 32 is worn, so the gasket 34 needs to be arranged above the retaining ring 32 and below the nut 35, and the connecting piece is fixed between the nut 35 and the gasket 34, so that the retaining ring 32 can be prevented from being worn in the process of fixing the connecting piece.

The retaining ring 32, the spacer 34, the first screw portion 36 and the second screw portion 37 are integrally connected.

The retaining ring 32, the gasket 34, the first screw part 36 and the second screw part 37 can adopt an integrally formed structure, and under the structure, the retaining ring 32, the first screw part 36 and the second screw part 37 are integrally connected, and joints among the components do not have gaps, so that the terminal 21 and the external environment can be better isolated, and the terminal 21 is better protected from corrosion; in the present embodiment, the retaining ring 32, the spacer 34, the first screw portion 36 and the second screw portion 37 are integrally connected.

In addition, the battery terminal protection sleeve 30 can also adopt a structure that a retaining ring 32, a gasket 34 and a first screw part 36 are detachably connected with a second screw part 37.

The retaining ring 32, the gasket 34, the first screw rod part 36 and the second screw rod part 37 are independent structures, a tight detachable connection structure is adopted between every two parts, under the structure, not only can the terminal 21 and the external environment be isolated well, but also the worn parts can be replaced conveniently, and the retaining ring 32, the gasket 34, the first screw rod part 36 and the second screw rod part 37 can be produced in batch, so that the production cost is further reduced.

The depth of the clamping groove 33 on the retaining ring 32 is at least equal to the height of the terminal 21 exposed out of the battery cover 20.

If the depth of the slot 33 is less than the height of the terminal 21 exposed outside the battery cover 20, the terminal 21 cannot be isolated from the external environment by the retaining ring 32, and the battery terminal protection sleeve 30 is difficult to achieve good corrosion resistance, so the depth of the slot 33 on the retaining ring 32 can be greater than the height of the terminal 21 exposed out of the battery cover 20, can be equal to the height of the terminal 21 exposed out of the battery cover 20, but cannot be less than the height of the terminal 21 exposed out of the battery cover 20; the depth of the card slot 33 of this embodiment is equal to the height of the terminal 21 exposed out of the battery cover 20.

When the terminal is used specifically, the first screw part 36 is screwed into the threaded hole of the terminal 21, the inner wall of the clamping groove 33 of the retaining ring 32 and the outer wall of the terminal 21 exposed out of the battery cover 20 are clamped, the terminal 21 is effectively separated from the external environment through the structure of combining the first screw part 36 and the retaining ring 32, namely, in the formation process, the terminal 21 is not in the environment with dilute sulfuric acid, the terminal is not corroded by the dilute sulfuric acid, after the formation is completed, the retaining ring 32 is detached from the terminal 21, and the first screw part 36 is rotated out of the threaded hole.
