Central controller for heavy-type automobile electric appliances

Abstract

The invention relates to a central controller for heavy-type automobile electric appliances. The central controller comprises a plastic casing, sockets for external connection with various relays, sockets for externally connecting to fuses of various specifications, jackets for external power supply, plugs for external connection with various electric appliances, various relays fuses of various specifications, copper bars and insulated panels for isolating the copper bars. The central controller is characterized in that the cooper bars are shaped through a cold stamping process according to requirements; the cooper bars, as current transmission conductors, are divided into five layers within the plastic casing and each layer is isolated by an insulation panel for avoiding collision and intersection of wiring. The said sockets for external connection with various relays, the sockets for external connection with fuses of various specifications, the jackets for external power supply and the plugs for external connection with various electric appliances are respectively connected to heads of the corresponding cooper bars and embedded in the front of the casing. The advantages of the central controller are that electric resistance of the centre controller is greatly reduced as well as the heat generated by current transmission due to sectional areas of the cooper bar is dozen times bigger than that of the conventional bars, so that the safe operation can be achieved.

Description

technical field [0001] The invention relates to an electric appliance controller, in particular to a heavy-duty automobile electric central controller. Background technique [0002] The central controller of heavy-duty automotive electrical appliances includes plastic shells, distribution circuit boards, various relays, fuses of various specifications and external plugs (heads). The distribution circuit board is usually made of bakelite board coated with copper plate, and the copper plate is corroded into independent lines according to the needs, as the power transmission line, one end of the external plug (head) seat is riveted on the bakelite board to connect with the copper strip, and inlaid In front of the shell, it is used to insert various relays and fuses of various specifications; it is used to insert external power supplies and various electrical appliances. At present, the central controller of heavy-duty automotive electrical appliances in China uses the copper st...

AI Technical Summary

Problems solved by technology

[0003] With the development of society, the power consumption of various electrical appliances of heavy-duty vehicles is increasing, so the current transmission through the copper strips on the bakelite board has greatly exceeded the original design value, and the heat generated often causes the bakelite board to burn , the short circuit of the copper bar occurs, and the damage rate is very high
