Summary of the invention
The purpose of this utility model is that a kind of assembling complexity that can overcome above-mentioned engineering machinery electrical equipment will be provided, make mistakes easily, inconvenient maintenance repair, and faults such as becoming flexible appears in lead easily, wearing and tearing, influence the central electric appliance control box of defective of the reliability of complete machine work, this control box assembling is simple, reliable operation, and it is convenient to safeguard, overhaul.
The purpose of this utility model is achieved in that this control box comprises housing and double-sided printed-circuit board, housing is provided with and installs and fixes the hole, the housing side is connected with connector, double-sided printed-circuit board is connected in the housing, be connected with general-purpose relay, LED light, fuse, mini relay and wholesale fuse on the double-sided printed-circuit board, plug-in and pull-out device is housed on housing, is connected with in the housing and the corresponding Sign Board of electric elements.
The utility model fuse, circuit turn-on and relay that entire machine is all is assembled into an assembly by printed circuit board (PCB) and housing, link to each other with the complete machine wire harness by connector, reach the purpose that above-mentioned electric elements are carried out centralized control, simplify circuit, conveniently overhaul and fix a breakdown.General-purpose relay and mini relay can be installed, and general chip fuse, mini chip fuse and the flat fuse of wholesale satisfy the circuit function requirement of engineering machinery.Blade inserting fuse and LED light that each road fuse output in central authorities' electric appliance control box all is furnished with specified volume, when fuse blows, the corresponding LED indicator light is lighted with it, and the handled easily person searches and fixes a breakdown; According to the characteristic of engineering machinery, adopt the side outlet method, have on the housing and the corresponding Sign Board of electric elements, make each electric elements Function Identification high-visible, the convenient installation and maintenance.Adopt double-sided printed-circuit board, housing adopts the manufacturing of flame-proof ABS engineering plastics, and heatproof degree humidity circulation change performance, vibration-resistant property, High-Voltage Insulation performance etc. meet the instructions for use of engineering machinery operating mode.
The utility model has the advantages that: volume is little, compact conformation, good looking appearance, has realized the centralized control of electric elements, has simplified the lead connection, and the functional reliability height is easy to assembling, conveniently overhauls and fixes a breakdown.And be reserved with the installation site of relay and fuse, after improving, can be used for different types, be convenient to realize generalization, the seriation of product.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 connector, 2 installs and fixes hole, 3 general-purpose relays, 4LED indicator light, 5 fuses, 6 Sign Boards, 7 housings, 8 mini relays, 9 wholesale fuses, 10 plug-in and pull-out devices.
Embodiment
In Fig. 1, housing 7 is provided with and installs and fixes hole 2, housing 7 downsides are connected with connector 1, and double-sided printed-circuit board is connected in the housing 7, are connected with general-purpose relay 3, LED light 4, fuse 5, mini relay 8 and wholesale fuse 9 on the double-sided printed-circuit board.Plug-in and pull-out device 10 is housed on housing 7, is connected with in the housing 7 and the corresponding Sign Board 6 of electric elements.
By installing and fixing hole 2 usefulness bolts or screw electric appliance control box is fixed in the machine cabin.Link to each other with the complete machine wire harness by connector 1, reach electric elements are carried out central controlled purpose.Main power source inserts in the housing 7 by connector 1, and the output of fuse 5, wholesale fuse 9 is connected electrical equipment power distribution in car by connector 1 with the complete machine wire harness.Outside control signal inserts in the electric appliance control box by connector 1, controls being switched on or switched off of general-purpose relay 3 and mini relay 8, and relay contact output is connected with the complete machine wire harness by connector 1, provides the control out-put supply to each electrical equipment.Plug-in and pull-out device 10 is housed on housing 7, is convenient to change general chip fuse 5.
