[0027] When in use, after the wiring is completed, the protective plate 4 and the second protective plate 7 can be flipped over to make the protective plate 4 and the second protective plate 7 parallel to the capacitor body 1. Then, the baffle 5 arranged on the surface of the protective plate 4 and the second protective plate 7 can be used to cover and protect the terminal arranged on the surface of the capacitor body 1 to prevent the terminal from being directly exposed to the outside. Embodiment 2

[0028] On the basis of the first embodiment, in order to facilitate the protection of the capacitor body 1, a protective plate 4 and a second protective plate 7 are provided, the rotating rod 2 is fixedly connected to the side of the capacitor body 1, the rotating plate 3 can rotate around the rotating rod 2, and the rotating plates 3 are provided with two groups, and the two groups of rotating plates 3 are symmetrically distributed about the capacitor body 1.

A transparent plate 8 is provided on the surface of the protective plate 4 and the second protective plate 7, and the baffle 5 is distributed and fixed on the surface of the protective plate 4 and the second protective plate 7;

[0029] When in use, the two sets of baffles 5 can be spliced ​​together by cooperating with the rotating rod 2 and the rotating plate 3, so that the terminals arranged on the surface of the capacitor body 1 can be covered and protected. The transparent plate 8 arranged on the surface of the protective plate 4 and the second protective plate 7 can facilitate observation of the terminals inside the cover. Embodiment 3

[0030] On the basis of the second embodiment, in order to facilitate the fixing of the two groups of baffles, a positioning plate 6 and a fixing plate 9 are provided, a fixing plate 9 is provided on the surface of the baffle 5 provided on the surface of the second protective plate 7, two groups of fixing plates 9 are provided, and the two groups of fixing plates 9 are symmetrically distributed about the baffle 5, a groove 10 is provided on the surface of the fixing plate 9, a support rod 11 is provided on the inner side of the groove 10, a bottom plate 12 is sleeved on the surface of the support rod 11, a spring 13 is sleeved on the surface of the support rod 11, a second baffle 18 is provided on the side of the fixing plate 9, and one end of the spring 13 is fixedly connected to the fixing plate 9.

In this way, the second baffle 18 can be used to prevent the bottom plate 12 from continuing to rotate, so that the positioning plate 6 can be fixed in the fixed plate 9, and the protective plate 4 and the second protective plate 7 will not continue to rotate. The setting of the spring 13 also prevents the problem of the bottom plate 12 rotating at will.

[0032] Working principle: In actual use, after the wiring is completed, the protective plate 4 and the second protective plate 7 can be flipped over to make the protective plate 4 and the second protective plate 7 parallel to the capacitor body 1, and then the baffle 5 arranged on the surface of the protective plate 4 and the second protective plate 7 can be used to cover and protect the terminal posts arranged on the surface of the capacitor body 1 to avoid the terminal posts being directly exposed to the outside world. This avoids the traditional problem that the capacitor body 1 cannot directly protect the terminal posts due to the protruding setting of the terminal posts, which is easy to cause damage to the terminal posts during use, thereby causing damage to the terminal posts and affecting the normal use of the power capacitor.
