The invention discloses an insulating buckle assembly and a dust collection assembly with the insulating buckle assembly. The insulating buckle assembly is characterized in that at least one first insulating buckle comprises a first body, at least two first clamping legs and a first clamping hook; the at least two first clamping legs extend downwards from the lower end of the first body; the first clamping hook extends upwards from the upper rend of the first body; a second insulating buckle comprises a second body, a second clamping hook and a lug boss; an opening is formed in the top of the second body and the bottom of the second body is opened; second clamping legs are arranged on the two opposite sides of the outer surface of the second body in a manner of extending outwards. According to the insulating buckle assembly disclosed by the invention, the first insulating buckle can be reliably connected between two parts by using the first clamping legs and the first clamping hook, and the second insulating buckle can be reliably connected between the two parts by using the second clamping legs, the second clamping hook and the lug boss, so that the structure of the first insulating buckle is simplified and the assembling efficiency is improved.
