[0032] Such as Figure 1 - Figure 2As shown, in this embodiment, the battery fuse terminal includes a terminal body 1, a terminal post 2, a fuse 3, and a protection member 5. Among them, the terminal post 2 is arranged on the terminal body 1. The fuse 3 is provided with an installation hole 4, and the fuse 3 is sleeved on the terminal post 2 through the installation hole 4. The protection member 5 is arranged between the terminal post 2 and the fuse 3. The inner ring of the protection member 5 is connected to the outer peripheral surface of the terminal post 2, and the outer ring of the protection member 5 is connected to the hole wall of the installation hole 4 of the fuse 3. Specifically, when the current exceeds the specified value for a period of time, the fuse 3 melts the fuse wire with the heat generated by itself, thereby disconnecting the circuit. It is widely used in high and low voltage power distribution systems, control systems, and electrical equipment. As a protector for short circuits and overcurrents, it is one of the most commonly used protection devices. The relationship between the battery and the terminal body 1 is to connect the battery and the external circuit through the terminal post 2 to achieve current transmission and the normal use of the battery, which is applicable to the positive and negative electrodes of the battery. The protection member 5 has a through hole, and the protection member 5 is sleeved on the outer periphery of the terminal post 2 through the through hole. The fuse 3 is provided with an installation hole 4, and the fuse 3 is sleeved on the outer periphery of the protection member 5 through the installation hole 4, that is, the protection member 5 is clamped between the terminal post 2 and the fuse 3. The fuse 3 and the terminal post 2 are integrally arranged, without the need for a connecting wire for connection, with a small volume, which can save lateral space and meet more functional layouts. Under the action of the protection member 5, this battery fuse terminal can achieve reliable circuit protection in a limited space. Optionally, the terminal body 1 of the battery matches the fuse 3, and the specifications range from 100A to 600A, and different fuses 3 can be selected according to different usage requirements.

[0033] Further, continue to refer to Figure 1 - Figure 2 , the protection member 5 is in a pipe structure. Specifically, the protection member 5 with a pipe structure is fixedly sleeved on the terminal post 2. Its main function is to protect the terminal post 2 from external environmental interference, ensure the safe transmission of the terminal post 2, and it is an important material for protecting the terminal post 2, preventing the terminal post 2 from short-circuiting, and achieving reliable circuit protection.

[0034] Further, continue to refer to Figure 1 - Figure 2 , the protection member 5 is made of electrical insulating material. Specifically, the insulating material is a material that does not conduct electricity under the allowable voltage. Under the action of a certain applied electric field strength, processes such as conduction, polarization, loss, and breakdown will also occur, and aging will occur during long-term use. The insulating material is also called a dielectric, which refers to a substance that does not conduct electricity or conducts extremely weakly under the action of a DC voltage. Its main function is to isolate charged conductors with different potentials in electrical equipment, so that the current can flow along a certain path. It can also play a role in mechanical support and fixation, as well as arc extinguishing, heat dissipation, energy storage, moisture-proof, mildew-proof, or improving the potential distribution of the electric field and protecting the conductor. Therefore, the protection member 5 can play a role in preventing short circuits and has high reliability.

[0035] Further, continue to refer to Figure 1 - Figure 2, there are two terminal posts 2, and the two terminal posts 2 are symmetrically distributed with respect to the central axis of the terminal body 1. Specifically, one end of the terminal post 2 is directly connected to the bus bar, and the other end is connected to an external conductor or to a pole of an adjacent single cell in the battery pack. The terminal post 2 is responsible for introducing or leading out external current in the storage battery, so as to ensure the normal operation of the storage battery. The number of both the fuse 3 and the protection member 5 is two. The two protection members 5 are respectively sleeved on the corresponding two terminal posts 2, and the two fuses 3 are respectively sleeved on the corresponding two protection members 5. The fuse 3 and the protection member 5 are in one-to-one correspondence. Under the action of the protection member 5, reliable circuit protection can be achieved within a limited space. The number of the fuse 3 and the protection member 5 is the same as that of the terminal post 2, with high integration degree, which can save the lateral space and meet more functional layouts.

[0036] Further, continue to refer to Figure 1 - Figure 2 , the protection member 5 is in interference fit with the terminal post 2. Specifically, the protection member 5 is made of a flexible material. By using the elasticity of the material, the through hole of the protection member 5 is enlarged and deformed to be sleeved on the terminal post 2. When the through hole is restored, a tightening force on the terminal post 2 is generated, so that the protection member 5 is connected to the terminal post 2, that is, the inner wall of the through hole of the protection member 5 closely fits on the outer periphery of the terminal post 2, preventing the connection between the protection member 5 and the terminal post 2 from falling off or relatively rotating.

[0037] Further, continue to refer to Figure 1 - Figure 2 , the fuse 3 is in interference fit with the protection member 5. Specifically, when the fuse 3 is sleeved on the protection member 5 through the mounting hole 4, by using the characteristics of the material of the protection member 5, the protection member 5 shrinks and can pass through the mounting hole 4 of the fuse 3, and then the protection member 5 is restored to generate a pressing force on the mounting hole 4 of the fuse 3, that is, the outer ring of the protection member 5 presses against the hole wall of the mounting hole 4, preventing the connection between the fuse 3, the protection member 5 and the terminal post 2 from falling off or relatively rotating.

[0038] Further, continue to refer to Figure 1 - Figure 2 , the central axes of the terminal post 2, the protection member 5 and the mounting hole 4 coincide. Specifically, the protection member 5 is in interference fit with the terminal post 2, and the fuse 3 is in interference fit with the protection member 5. At this time, the central axis of the terminal post 2, the central axis of the through hole of the protection member 5 and the central axis of the mounting hole 4 of the fuse 3 are collinear.

[0039] Further, continue to refer to Figure 1 - Figure 2, the terminal body 1 has a T-shaped structure. Specifically, the terminal body 1 includes two wiring parts and a connecting part. The wiring parts and the connecting part are perpendicularly arranged, and the two wiring parts are respectively arranged at both ends of the connecting part. The wiring part is provided with a terminal post 2, and a protective part 5 and a fuse 3 are sequentially and fixedly sleeved on the terminal post 2. They are integrally arranged without the need for connection wires, with a small volume, which can save lateral space and meet more functional layouts. Under the action of the protective part 5, this battery fuse terminal can achieve reliable circuit protection in a limited space.

[0040] This embodiment also provides a vehicle, including a battery and a battery fuse terminal. The battery fuse terminal is electrically connected to the battery. Specifically, the fuse 3 and the terminal post 2 are integrally arranged without the need for connection wires, with a small volume, which can save lateral space and meet more functional layouts of the battery. The protective part 5 is clamped between the terminal post 2 and the fuse 3. Under the action of the protective part 5, reliable circuit protection of the battery can be achieved in a limited space.

[0041] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
