Technical Field

[0001] The utility model relates to the technical field of sealed terminals, in particular to a battery sealed terminal and a battery. Background Art

[0002] The existing battery terminal sealing structure is single, which is sealed with the terminal periphery by the cooperation of a sealing ring and a colloid, and its sealing effect is limited. Therefore, we propose a battery sealed terminal and a battery. Utility Model Content

[0003] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a battery sealing terminal and a battery.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a battery sealed terminal and a battery, including a battery and a terminal structure, a sealing top groove is opened on the top of the battery, a sealing bottom groove is opened on the inner bottom surface of the sealing top groove, a sealing sleeve is arranged inside the sealing bottom groove and is sleeved on the outer packaging of the terminal structure, a sealing gasket is arranged inside the sealing top groove and is sleeved on the outer side of the terminal structure, and a sealing screw ring with three seals is installed on the periphery of the terminal structure through an assembly thread.

[0005] Preferably, the inner wall of the sealing sleeve is sealed together with the sealing threads on the periphery of the terminal structure through a sealing screw groove.

[0006] Preferably, the textured surface of the assembly thread itself is provided with a corresponding thread pad, and the encapsulation screw ring is installed with the assembly thread on the periphery of the terminal structure, and the thread pads on the surface of the assembly thread can be engaged and encapsulated with each other.

[0007] Preferably, the sealing sleeve and the terminal structure are packaged with outer threads and the sealing sleeve can be limited and matched with each other through the packaging threads.

[0008] Beneficial Effects

[0009] The utility model provides a battery sealed terminal and a battery, which has the following beneficial effects:

[0010] (1) A battery sealed terminal and a battery, wherein the terminal structure peripheral integral assembly can be used to seal the terminal structure and the inside of the battery. The existing battery terminal sealing structure is single, and it is sealed with the terminal periphery by the cooperation of a sealing ring and a colloid, and its sealing effect is limited. The terminal structure inside the battery can first be sealed and limited by the sealing thread on the periphery of the terminal structure, so that the first sealing operation can be performed, and the sealing gasket can be sleeved on the outside of the terminal structure for secondary sealing. Then, the sealing screw ring is threadedly installed between the assembly thread above the periphery of the terminal structure and the terminal structure to press the sealing gasket. At the same time, the threaded gasket on the surface of the assembly thread can also form a further bite seal with the internal thread of the sealing screw ring, so that the three seals are achieved. In this way, the multiple sets of sealing mechanisms can ensure the sealing effect of the electrolyte inside the battery under mutual sealing, and form a blocking barrier in sequence through the threads to ensure the sealing effect of the sealing assembly itself, thereby improving the sealing effect of the terminal structure itself.

[0011] (2) A battery sealed terminal and a battery. After the sealing sleeve is threadedly assembled with the sealing threads on the periphery of the terminal structure through the sealing screw groove, its multiple sets of sealing threads can form multiple sets of blocking barriers. At the same time, the sealing sleeve can also be limited and engaged through the multiple sets of sealing threads to avoid dislocation. The terminal structure itself can be further extruded and engaged with the sealing screw ring through the thread pad on the surface of the assembly thread, thereby increasing the friction resistance between the sealing screw ring and the terminal structure, thereby achieving the effect of improving the installation stability of the terminal structure's own sealing component.
