The cover plate 420 covers the surface of the sealing gasket 430 to extrude the sealing gasket 430, the cover plate 420 can be made of the same material as the top cover body 450, for example, aluminum material is adopted, and the cover plate is fixed with the top cover body in a welding mode, the cover plate 420 extrudes the sealing gasket 430 downwards, the sealing gasket 430 further extrudes the adapter plate 510, so that the adapter plate 510 can be better attached to the protruding part 440 in the fixing hole 410, and a good sealing effect is achieved.

In some embodiments, when the adaptor 530 is disposed in the transfer hole 520, it is necessary to ensure the sealing performance between the adaptor 530 and the transfer hole 520. In some embodiments, an external thread is disposed on the outer circumference of the adaptor 530, an internal thread is disposed on the inner wall of the transfer hole 520, and the adaptor 530 is screwed into the transfer hole 520.

Through with adaptor 530 spiro union in the switching hole 520, the sealing connection between adaptor 530 and the switching hole 520 can be fine realization, simultaneously, in order to strengthen sealed effect, can be when the spiro union, at first scribble glue on the surface of screw thread, and the spiro union back, glue dries out, can reach better sealing performance.

In some embodiments, in order to achieve better sealing performance between the adaptor 530 and the adaptor hole 520, as shown in fig. 6, a protrusion 535 is disposed on the outer periphery of the adaptor 530, and the protrusion 535 is in interference fit with the adaptor hole 520 to fix the adaptor 530 in the adaptor hole 520.

In order to realize adaptor 530's quick installation, also reach better sealing performance simultaneously, consider that the switching hole adopts the plastic material to make, has certain elasticity, and this application embodiment sets up bellying 535 through the periphery at adaptor 530, is impressing adaptor 530 when switching hole 520, bellying 535 with the inner wall that switches hole 520 produces interference fit, bellying 535 outwards extrudees the inner wall that switches hole 520 produces elastic deformation, can reach better sealed effect. Further, glue can be applied to the periphery of the adapter 530, and after the adapter 530 is pressed into the adapter hole 520, the glue dries out, so that the sealing performance is better.

In some embodiments, in order to prevent the adaptor 530 from rotating in the adaptor hole 520 during use, as shown in fig. 6 and 7, a limiting groove 533 is disposed on an inner wall of a top end of the adaptor hole 520, and a limiting member 532 is disposed on an outer wall of the adaptor 530 at a position corresponding to the limiting groove 533; the limiting member 532 is used for fixing and limiting the adaptor 530.

The limiting member 532 is disposed at the top end of the adaptor 530, and may be disposed one or more, and the specific shape may be formed integrally with the adaptor 530 in various ways, and the limiting member 532 extends to the outside of the adaptor 530, and is matched with the adaptor hole 520 to limit the adaptor 530. A limiting groove 533 is formed in the inner wall of the top end of the transfer hole 520 at a position corresponding to the limiting member 532, and the limiting member 532 is located in the limiting groove 533 to fix and limit the transfer member 530. In this way, the adaptor 530 can be prevented from rotating in the adaptor hole 520 during use, and the measurement performance can be prevented from being affected.

In some embodiments, in order to be able to fix the cable in the hollow structure of the adaptor 530, as shown in fig. 6, a release prevention member 534 is provided on the inner wall of the adaptor. The anti-falling member 534 is an elastic sheet, can be made of aluminum alloy material, can also be made of other materials, and can be integrally formed with the adapter 530. When the cable 60 is inserted into the hollow structure of the adaptor 530, the anti-falling part 534 can clamp the cable, so as to prevent the cable 60 from falling off in the using process.

Fig. 7 is a general sectional view of the adaptor assembly 500 and the top cap body 450 after being hermetically connected, and it can be seen from fig. 7 that the adaptor assembly 500 is tightly pressed on the protrusion 440 in the fixing hole of the top cap body 450 by the sealing ring 430 and the cover plate 420, the adaptor 530 is fixed in the adaptor hole, the positive cable 610 and the negative cable 620 at the upper and lower ends are respectively inserted into the hollow structure in the adaptor 530, and the cables at the two sides are connected together by the adaptor 531. Through the scheme that this application embodiment provided the switching subassembly that sets up on the battery top cap can be convenient connect the cable of battery top cap both sides, has also played very good sealed effect simultaneously, has solved the problem that exists among the prior art.
