[0024] As Figure 3The protective plate 4 shown, a limiting groove 401 with a trapezoidal structure is formed at the top of the inner end face of the protective plate 4. A plurality of uniformly distributed second connection holes 402 that communicate with the first connection holes 503 are formed through the protective plate 4. By providing connection bolts 6 that are fitted through the first connection holes 503 and the second connection holes 402, the adjusted pressure plate 5 can be limited and fixed. The second connection holes 402 communicate with the limiting groove 401. A second installation hole 403 that communicates with the first installation hole 507 is formed through the protective plate 4. By providing installation bolts 7 that are fitted through the second installation hole 403 and the first installation hole 507, the pressure plate 5 that clamps the busbar housing 2 can be fixed, improving the fixing property of the pressure plate 5 for clamping the busbar housing 2.

[0025] Combined with Figures 4-5 The pressure plate 5 shown, limiting blocks 502 that are slidably connected to the limiting groove 401 are symmetrically provided on both sides of the top of the pressure plate 5, and the limiting blocks 502 fit with the limiting groove 401.
