[0049] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] See also Figures 1 to 4As shown, an embodiment of the present application provides a lead-out terminal of a battery, comprising a terminal body 1 and a terminal cover 2. The terminal body 1 comprises a terminal body 11 and an electrical connection portion 12 and a connection matching portion 13 arranged on the terminal body 11. The terminal cover 2 comprises a cover body 21 and a connection portion 22 connected to the cover body 21, and the connection portion 22 is movably connected to the connection matching portion 13. The terminal cover 2 has a closed state and an open state. In the closed state, the terminal cover 2 covers the electrical connection portion 12, and in the open state, the electrical connection portion 12 is exposed to the terminal body 1 and the terminal cover 2. The terminal cover 2 and the terminal body 1 of the lead-out terminal of the battery of the present application are movably connected. When the terminal cover 2 needs to be opened to expose the electrical connection portion 12, it is only necessary to move the terminal cover 2, and the terminal cover 2 does not need to be separated from the terminal body 1. In this way, the problem of the terminal cover 2 being lost is avoided, and the terminal cover 2 can also be avoided to the greatest extent from being damaged by pressure.

[0051] In a possible implementation, the connection fitting portion 13 includes a shaft slot 134, and the connection portion 22 includes a shaft 221, which is rotatably connected to the shaft slot 134. When the terminal cover 2 needs to be opened to expose the electrical connection portion 12, the terminal cover 2 only needs to be rotated.

[0052] In a possible implementation, the connection fitting portion 13 includes a mounting groove 135 connected to the shaft groove 134, and the width of the mounting groove 135 is smaller than the cross-sectional diameter of the shaft 221. During the process of inserting the shaft 221 into the shaft groove 134, the connection fitting portion 13 is deformed, and the mounting groove 135 is stretched open. When the shaft 221 is completely accommodated in the shaft groove 134, the connection fitting portion 13 recovers its deformation, and the shaft 221 is confined in the shaft groove 134. The mounting groove 135 and the shaft groove 134 are matched to facilitate the installation of the shaft 221 into the shaft groove 134, and the shaft 221 can be stably placed in the shaft groove 134 and is not easy to fall out.

[0053] In a possible implementation, the connection fitting portion 13 includes a first extension plate 131 and an arc-shaped connector 132 disposed on the first extension plate 131. The first extension plate 131 is connected to the terminal body 11, and the arc-shaped connector 132 is connected to the first extension plate 131. The shaft groove 134 and the mounting groove 135 are formed between the arc-shaped connector 132 and the first extension plate 131. The first extension plate 131 extends in the direction of the threaded hole of the electrical connection portion 12, and the arc-shaped connector 132 is disposed on a side of the first extension plate 131 away from the terminal body 1. When the terminal cover 2 is in a closed state, the terminal body 11 and the terminal cover 2 enclose a cavity, and the cavity needs to accommodate the connection fitting portion 13, the connecting copper bar and the fasteners, etc., so the cavity needs a certain height. The provision of the first extension plate 131 increases the height of the terminal body 1, thereby ensuring the height of the cavity.

[0054] In a possible implementation, the connection matching portion 13 includes two arc-shaped connectors 132, and the two arc-shaped connectors 132 are arranged at intervals. The connection portion 22 includes a connector connecting the rotating shaft 221 and the cover body 21, and the connector is located between the two arc-shaped connectors 132, and the shaft sections of the rotating shaft 221 located on both sides of the connector are rotatably connected to the rotating shaft grooves 134 of the two arc-shaped connectors 132. When the terminal cover 2 is rotated to open, space needs to be reserved between the two arc-shaped connectors 132 for the connector. Therefore, the arc-shaped connector 132 is arranged as two interval sections to cooperate with the rotating shaft 221 at both ends, so that the terminal cover 2 can be opened and closed more smoothly.

[0055] In a possible implementation, the connector includes a plurality of reinforcing ribs 222 arranged at intervals, and each of the reinforcing ribs 222 is connected to the rotating shaft 221 and the cover body 21. The plurality of reinforcing ribs 222 are arranged at intervals along the length direction of the rotating shaft 221. The structure with the plurality of reinforcing ribs 222 has high strength, and the connection points are not easily damaged, thereby improving the connection firmness between the terminal cover 2 and the terminal body 1.

[0056] In a possible implementation, the terminal body 1 includes a snap-fit ​​seat 14, which is connected to the side of the terminal body 11 away from the connection fitting portion 13. The terminal cover 2 includes a snap-fit ​​seat 23, which is connected to the side of the cover body 21 away from the connection portion 22. In the closed state, the snap-fit ​​seat 23 and the snap-fit ​​seat 14 are snap-fitted and fixed. The snap-fit ​​seat 14 cooperates with the snap-fit ​​seat 23 to ensure that the terminal cover 2 is stable when closed, and makes it convenient to open the terminal cover 2 when it is needed.

[0057] like Figure 2 and Figure 4As shown, the snap-fit ​​seat 14 includes a second extension plate 141 and a snap-fit ​​protrusion 142, the second extension plate 141 is connected to the terminal body 11, the snap-fit ​​protrusion 142 is arranged on the second extension plate 141, and the snap-fit ​​seat 23 has a snap-fit ​​hole 231. In the closed state, the snap-fit ​​protrusion 142 is snapped into the snap-fit ​​hole 231. When the terminal cover 2 needs to be switched from the closed state to the open state, the outer edge of the snap-fit ​​seat 23 can be moved outward to disengage the snap-fit ​​protrusion 142 from the snap-fit ​​hole 231, and then the terminal cover 2 is rotated so that the snap-fit ​​hole 231 can be smoothly moved away from the snap-fit ​​protrusion 142.

[0058] In a possible implementation, a recessed portion 143 is provided on the second extension plate 141, and the locking protrusion 142 is located in the recessed portion 143. In the closed state, the clamping seat 23 is embedded in the recessed portion 143. In this way, when the terminal cover 2 is in the closed state, the outer surface of the clamping seat 23 can be smoothly connected to the peripheral side structural surface where the recessed portion 143 is provided on the terminal body 11, and the clamping seat 23 does not protrude from the structural surface, so the clamping seat 23 is not easily subjected to external force to cause the terminal cover 2 to be opened by mistake or damaged.

[0059] In the closed state, there is a gap between the terminal cover 2 and the terminal body 11 to avoid the copper bar. Copper bars extend into both sides of the lead-out terminal to connect to the electrical connection part. The setting of the gap prevents the terminal cover 2 from interfering with the copper bar in the closed state, so that the copper bar can be smoothly connected to the electrical connection part 12 in the terminal body 11. The electrical connection part 12 can be a metal cylinder with a threaded groove in the middle. The copper bar can cover the notch of the threaded groove, and one end of the bolt can pass through the copper bar and connect to the threaded groove.

[0060] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model has been disclosed as a preferred embodiment as above, it is not used to limit the utility model. Any technician familiar with this patent can make some changes or modify the technical content suggested above into an equivalent embodiment with equivalent changes without departing from the scope of the technical solution of the utility model. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the content of the technical solution of the utility model still falls within the scope of the solution of the utility model.
