Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Embodiment 1:

With reference to accompanying drawing 2; a kind of bus duct with protective device 3; comprise bus duct body 1 and copper bus-bar 2; protective device 3 comprises fixed block 31 and lower fixed block 32; upper fixed block 31 and lower fixed block 32 form by substrate and the fixing insertion 33 being fixed on substrate; being shaped as of fixing insertion 33 is rectangular-shaped, and the length of fixing insertion 33 is 1/2nd of copper bus-bar 2 length, and gap and quantity that the quantity of fixing insertion 33 is adjacent with needing fixing copper bus-bar 2 with size are identical.

With reference to accompanying drawing 3,4, and be provided with supple buffer layer 34 in the both sides of fixing insertion 33, the material of supple buffer layer 34 can adopt rubber or foam etc., thickness can be 1mm to 3mm, when fixing insertion 33 inserts the gap between copper bus-bar 2, supple buffer layer 34 can play to be avoided and situation about scratching in the contacting of copper bus-bar 2.

And the opposite side with respect to substrate at the fixing insertion 33 of upper fixed block 31 is provided with a projection 311, the opposite side with respect to substrate at the fixing insertion 33 of lower fixed block 32 is provided with a recess 321, the fixing insertion 33 that can certainly be upper fixed block 31 is provided with recess 321, and the fixing insertion 33 of lower fixed block 32 is provided with projection 311 corresponding thereto.
