Abstract
A power supply feed structure is provided with a bus bar, which mainly comprises a screw, a gasket, an insulating plate and a bus bar sheet, wherein the insulating plate and the bus bar sheet are arranged in an interval superposition way, the insulating plate and the bus bar sheet are fixedly connected by the screw and the gasket, and two ends of the bus bar sheet are respectively provided with a power supply input and output perforated joint. The invention can effectively reduce the noise of the feed system; the bus bar does not have an insulating layer of a round plastic wire, so that the space occupied by the feeder line can be saved; the flat structure of the bus bar has better heat dissipation property than the round wire under the same sectional area; because the sectional area of the bus bar is larger, the bus bar has small direct current resistance, so the voltage drop on the bus bar is small, and the voltage drop of a power supply and the ground potential drift can be reduced; the single bus bar is provided with more than two input/output connectors, so that the manufacturability of product assembly is improved, the circuit inspection is facilitated, and the assembly can be simplified.
Description
Technical field
The present invention relates to the Electronic Control Unit technical field, relate in particular to a kind of feeding structure of power supply.
Background technology
Along with the develop rapidly of aeronautical and space technology, increasing application scenario proposes the requirement of high reliability to the power feed of Electronic Control Unit.Because the functional module of Electronic Control Unit is many, all needs to connect power supply, and required supply voltage also is not quite similar, and conventional power feed is in the lead mode, and the shared space of this feed mode is big, and lead is difficult for heat radiation; The noise that feed system is produced is big; Supply voltage falls with earthy drift big; The whole assembling of circuit is complicated.
Summary of the invention
The objective of the invention is in order to overcome deficiency of the prior art, provide a kind of little, easy heat radiation that takes up room, noise is little, supply voltage the falls feeding structure of power supply less, simple in structure with earthy drift.
A kind of feeding structure of power supply is equipped with busbar on this structure, and it mainly comprises screw, packing ring, insulation board, sheet confluxes.The described insulation board and the sheet setting that superposes at interval of confluxing are fixedlyed connected with packing ring by screw between the two.The described sheet two ends of confluxing respectively are provided with a power supply input and output ported sub.
Adopt the beneficial effect of technique scheme to be:
1, can effectively reduce the noise of feed system;
2, there is not the insulating barrier of round plastic lead in busbar, saves lead and ties up shared space, thereby can save the shared space of feeder line;
3, the flat structure of busbar is better than round conductor at the long-pending heat dissipation characteristics down of same cross-sectional;
4, because the sheet sectional area that confluxes is bigger, make it that very little D.C. resistance be arranged, therefore the pressure drop on the sheet that confluxes is little, therefore can reduce supply voltage and fall with earth potential and drift about;
5, two above input and output joints are arranged on the single sheet that confluxes, improve the manufacturability of product assembling, be convenient to channel check, thereby can simplify assembling.
Description of drawings
Fig. 1 is a kind of feeding structure of power supply schematic diagram of the present invention.
Fig. 2 is that a kind of feeding structure of power supply of the present invention is applied in the structural representation in the electrical control combination.
Among the figure: 1-screw, 2-packing ring, 3-insulation board, 4-conflux sheet, 5-busbar
Embodiment
The invention will be further described below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of feeding structure of power supply of the present invention mainly comprises screw 1, packing ring 2, insulation board 3, sheet 4 confluxes.The described insulation board 3 and the sheet 4 stack setting at interval of confluxing are fixedlyed connected with packing ring 2 by screw 1 between the two.
The electric current that passes through according to the power feed needs is selected the conductor design sheet 4 that confluxes well, for the ease of the assembling of product, respectively is provided with a power supply input and output ported sub at single sheet 4 two ends of confluxing.The described sheet 4 that confluxes is more than two, and the sheet 4 of confluxing is made by brass sheet, and the centre is real copper coin, is mainly overcurrent, and ported sub on every side is used for welding lead.Described insulation board 3 is made by epoxy phenolic laminated glass fabric plate, plays insulation and isolates.Described insulation board 3 is more than two.
With two sheet 4 stacks at interval of confluxing with upper insulation plate 3 and more than two, be fixed with screw 1, packing ring 2 and make busbar 5 together, promptly form a feeding structure of power supply.This structure is a flat structure.
As shown in Figure 2, busbar 5 of the present invention is applied in the electrical control combination, as its power feed mode, surface power supply power supply and other power supply sources (as: battery) are connected on the busbar 5, are fed to electrical control by busbar 5 and make up each functional module with busbar 5.
