In the battery, the bus member of the battery module is required to be connected with the high-voltage connecting member, and the high-voltage connecting member can be connected with the electric device to transmit the electric energy of the battery module. Therefore, the connection stability between the bus member and the high-voltage connection member is very important. In the process of assembling the battery module to the battery box, certain deviation exists between the relative positions of the converging part and the box, and if the positions of the output pole bases are fixed, certain distance or error may exist between the converging part and the output pole bases, so that the converging part and the output pole bases cannot be firmly connected.

Aiming at the situation, the embodiment of the application provides the output electrode connecting piece, and the insulation between the converging component and the box body of the battery as well as between the high-voltage connecting piece and the box body of the battery is realized by arranging the insulation box in the output electrode connecting piece, so that the risk of short circuit of the battery monomer is reduced, and the running safety of the battery is improved. And moreover, the sliding block and the connecting component can move along the first direction relative to the insulating box so as to absorb the dimensional deviation or assembly error between the converging component and the high-voltage connecting piece and the box body in the first direction, improve the flexibility and adaptability of assembly, and enhance the connection strength and connection stability between the converging component and the high-voltage connecting piece and the box body, thereby improving the stability of battery operation.

The output pole connector, the battery and the electric device according to the embodiment of the application are described in detail below with reference to the accompanying drawings. Referring to fig. 4 to 6, fig. 4 is a schematic structural diagram of an output pole connector according to an embodiment of the present application, fig. 5 is an exploded structural diagram of an output pole connector according to an embodiment of the present application, and fig. 6 is a schematic structural diagram of an output pole connector according to another embodiment of the present application.

As shown in the figure, the output pole connection piece 8 provided in the embodiment of the present application includes an insulation box 801, a slider 802, and a connection component 803. The insulating case 801 has an inner cavity, the insulating case 801 is used for being mounted to the case 5 of the battery 2, and the insulating case 801 is provided with a displacement groove 804 communicating with the inner cavity. The slider 802 is disposed in the cavity, at least a portion of the surface of the slider 802 is exposed from the displacement slot 804, and the slider 802 is movable in the first direction X relative to the insulating case 801. The connection assembly 803 is used to electrically connect the bus bar 601 of the battery module 6 and the high voltage connection of the battery 2, one end of the connection assembly 803 passes through the displacement groove 804 and fixes the bus bar 601 and the high voltage connection to the slider 802, and the connection assembly 803 is movable in the first direction X in the displacement groove 804.

In the technical scheme of the embodiment of the application, through arranging the insulation box 801, insulation between the bus component 601 and the high-voltage connecting piece and the box body 5 of the battery 2 is realized, the risk of short circuit of the battery cell 7 is reduced, and the running safety of the battery 2 is improved. Moreover, the slider 802 and the connection assembly 803 can move along the first direction X relative to the insulating box 801 to absorb dimensional deviations or assembly errors between the bus member 601 and the high-voltage connection member and the case 5 in the first direction X, so that flexibility and adaptability of assembly are improved, strength and connection stability of connection between the bus member 601 and the high-voltage connection member and the case 5 are enhanced, and stability of operation of the battery 2 is improved.

In some embodiments of the application, the displacement slot 804 is provided on the side of the insulating box 801 facing away from the housing 5. In the above technical solution, the displacement groove 804 is formed on the surface of the insulation box 801 facing away from the box body 5, so that the slider 802 and the connection component 803 can move in parallel along one direction of the surface of the box body 5, absorb dimensional deviation or assembly error in the width direction or the length direction of the box body 5, and improve the strength of connection between the bus component 601 and the high-voltage connection piece and the box body 5.

In some embodiments of the application, the slider 802 is movable relative to the insulating box 801 in a second direction Y, and the connection assembly 803 is movable in a displacement slot 804 in the second direction Y, which intersects the first direction X. Illustratively, the first direction X is perpendicular to the second direction Y, the first direction X being the length direction of the insulation box 801, and the second direction Y being the width direction of the insulation box 801. The displacement groove 804 in the above-described structure may extend a certain length in the second direction Y so that the slider 802 and the connection assembly 803 can move in the second direction Y.

In the above-described structure, the slider 802 is movable in the first direction X and the second direction Y with respect to the insulating case 801, and therefore, in the assembling process of the output pole connection member 8, the slider 802 and the connection member 803 can be moved in parallel in two directions along the surface of the case 5, and dimensional deviation and assembling errors in the width direction or the length direction of the case 5 can be absorbed, so that the strength of connection between the bus member 601 and the high-voltage connection member and the case 5 can be improved.

This design can increase the flexibility and adaptability of the overall system, so that the slider 802 and the connection assembly 803 can be adjusted in position within a range to accommodate variations in the size of the housing 5. The size of the case 5 is inevitably deviated due to various factors during the manufacturing and assembly processes. If these deviations are outside the allowable range, it may cause the slider 802 and the connection assembly 803 to be not properly installed or to malfunction in use. Therefore, the design can effectively absorb the deviations, and the reliability and the stability of the whole system are improved. In addition, the design can simplify the production and assembly process and improve the production efficiency. Since the slider 802 and the connection member 803 can be moved in parallel in two directions along the surface of the case 5, it is unnecessary to excessively pursue the accuracy of the dimensional matching in the actual production and assembly process, thereby simplifying the production and assembly process. Meanwhile, the design can reduce the requirement on the skill of workers, so that the production process is easier to control and manage.

In some embodiments of the present application, insulation box 801 includes an insulation cover 805 and an insulation shell 806. The displacement groove 804 is disposed on the insulating cover 805, the insulating housing 806 has an opening, the insulating cover 805 covers the opening, and the insulating housing 806 and the insulating cover 805 enclose an inner cavity together. In the above-described structure, an opening is provided in the insulating housing 806 to facilitate the entry of the slider 802 into the cavity, improving the efficiency of assembly. By providing the insulating cover 805, dust, dirt, and other particles in the external environment can be effectively blocked, thereby ensuring the cleanliness and safety of the internal components of the insulating case 801.

Illustratively, the structure of the insulating cartridge 801 includes two main portions, an insulating cover 805 and an insulating housing 806. The insulating cover 805 has a displacement slot 804 and the insulating housing 806 has an opening to allow the slider 802 or other component to conveniently access its interior space, i.e., the interior cavity. During assembly, insulating cover 805 may be placed over the opening of insulating housing 806 and enclose a semi-enclosed interior space with insulating housing 806. This lumenal space provides protection and support for the components or assemblies that need insulation. The main purpose of the openings is to improve the assembly efficiency. Through the opening, the slider 802 or other components can be conveniently accessed into the interior cavity, simplifying the assembly process and reducing time and labor costs. Meanwhile, the design of the opening is also beneficial to more convenient observation and maintenance of the insulation box 801 in the production and assembly processes. In addition, the insulating cover 805 is provided for the reason of reducing the risk of impurities entering the inside of the insulating case 801, which can avoid performance degradation, malfunction, and even safety problems of the battery 2. By using the insulating cover 805, dust, dirt, and other particles in the external environment can be effectively blocked, thereby ensuring the cleanliness and safety of the internal components. In summary, the structural design of the insulation box 801 considers the requirements of practical application, not only can improve the assembly efficiency, but also enhances the protection of the internal components by providing the insulation cover 805, ensuring the performance and reliability thereof. The design embodies the application value of engineering and technology in solving practical problems and meeting application requirements.

In some embodiments of the present application, the insulating housing 806 is provided with a guide rail extending along the first direction X, the slider 802 is provided with a groove matching with the guide rail, and the slider 802 is slidably connected to the insulating housing 806 through the guide rail and the groove. In the above-mentioned solution, by providing the guide rail extending along the first direction X on the insulating housing 806 and providing the groove on the slider 802 to be matched with the guide rail, the slider 802 can slide along the guide rail and form a sliding connection with the insulating housing 806. This configuration provides better guidance and stability, and allows the slider 802 to move more smoothly, reducing friction and drag.

In some embodiments, the slider 802 is provided with a threaded hole 807, and the connection assembly 803 includes a connection bolt that is coupled to the slider 802 through the threaded hole 807. Illustratively, a nut is disposed at an end of the connecting bolt away from the slider 802, the connecting bolt sequentially passes through the high-voltage connector and the bus member 601, electrically and structurally connects the high-voltage connector and the bus member 601, and an end of the connecting bolt extends into the bolt hole to be connected with the slider 802.

In the above-described structure, the design of the screw hole 807 allows a tight fit between the connecting bolt and the slider 802, which increases the rigidity and reliability of the connection, can improve the stability and reliability of the connection, and is also advantageous in simplifying the production and assembly process.

In some alternative embodiments, the slider 802 is fabricated using an insulating material. The slider 802 is provided in the insulation case 801, which can form good insulation with the case 5 by the insulation case 801. To further improve the insulating protection performance, the slider 802 is also manufactured using an insulating material.

In some embodiments of the present application, a plurality of limit protrusions 808 are disposed on a side of the slider 802 facing the insulating cover 805, and a plurality of limit grooves are disposed on a side of the insulating cover 805 facing the slider 802, and at least a portion of the limit protrusions 808 cooperate with a portion of the limit grooves to limit movement of the slider 802 relative to the insulating housing 806. Alternatively, the limiting protrusion 808 may be a strip-shaped protrusion, where the strip-shaped protrusion extends along the first direction X, and the limiting groove also extends along the first direction X, and the above structure can limit the movement of the slider 802 relative to the insulation box 801 along the second direction Y.

In the above structure, the cooperation of the limit protrusion 808 and the limit groove can limit the movement range of the slider 802 in the insulating housing 806, so as to prevent the slider 802 from moving or dislocating accidentally.
