Circuit framework

The utility model discloses a circuit framework comprising a support plate, wherein, an installation base used for fixing a circuit board is arranged on the support plate, and a wire gathering part used for gathering wires arranged on the circuit board in a cross-over manner is also arranged on the support plate. As wire chases are formed on two sides of the support plate, and central wires on the circuit board are connected through the wire chases in the cross-over manner, therefore, the congested space and the hidden danger, which are caused by the central wires passing through the bottom part of the circuit board, are avoided; the space is effectively utilized to the greatest extent; and the safe and reliable assembly of the circuit board and the central wires is ensured.
