The two limiting plates 24 are symmetrically arranged at the bottom of the baffle 21 and above the connecting plate 22. An insulating cover 4 is provided between the two wing plates 23 and the two limiting plates 24. The limiting effect of the two wing plates 23 and the two limiting plates 24 facilitates the pre-positioning of the insulating cover 4 during installation, thereby improving the accuracy of the position during installation.

[0032] In some embodiments, the insulating connection assembly 5 includes a screw 51, a locking nut 52, a washer 53, and an insulating sleeve 54. The screw 51 passes through two metal supports 2.
