Abstract
The utility model discloses an electronic igniter for vehicles, comprising the metal housing or the metal soleplate of an electronic igniting module, a Darlington switching tube and an insulated heat-conducting adhesive. The utility model is characterized in that the Darlington switching tube in the electronic igniting module is directly arranged in the slot of the metal housing or the metal soleplate of the electronic igniting module, the Darlington switching tube is arranged between the metal housing of the electronic igniting module and the circuit board of the electronic igniting module, and the insulated heat-conducting adhesive and the circuit board of the electronic igniting module are glued. The utility model with simple structure does not occupy the plane position of the circuit board, the heat of the Darlington switching tube is directly passed to the metal housing or the metal soleplate of the electronic igniting module to emit, the temperature rise of the circuit board is reduced, and the reliability and the service life of the electronic igniter are increased.
Description
The utility model belongs to a kind of electronic ignition device for automobile (module), is particularly useful in the ignition system such as lorry, Light-duty Vehicle, car of various internal-combustion engines.
At present in the world, the Darlington switching tube that adopts in the electronic ignition device (switching tube of electronic ignition device control ignition coil break-make) generally all adopts not packaged die (also claiming bare chip), this technological requirement height, and difficulty is big.Technology such as the subsides on chip of domestic naked core, sintering, lead-in wire do not reach a standard, and yield rate is low.So packaged switching tube is assembled or adopted to the domestic thick film circuit board of import that can only lean at present, this technology has significant disadvantages: the one, and switching tube occupies greatly, makes ignition mechanism boundary dimension and structure be difficult to meet the demands; The 2nd, the heat of switching tube can only (domestic is that switching tube is installed on the thick film circuit board) pass to the shell heat radiation by circuit board, and the temperature rise of circuit board is improved, and worsens the operating ambient temperature condition of circuit board.
The purpose of this utility model has provided a kind of electronic ignition device for automobile, packaged switching tube is contained in the metal shell or metal base plate of electronic ignition module, do not account for the planar dimension of electronic ignition module circuit board, heat is directly shed by metal shell, improved the reliability and the working life of electronic ignition device.
To achieve these goals, the utility model is by the following technical solutions: the Darlington switching tube of control ignition coil in the electronic ignition device directly is contained in the metal shell or metal base plate of electronic ignition device, that is to say, switching tube is contained in the middle of metal shell or metal base plate and the circuit board, do not account for the plan-position of circuit board, the space rigging position of electronic ignition module power tube and the radiating condition of power tube have been solved, improve the working environment of circuit board, thereby fundamentally solved the problem of the production and the application of electronic ignition device for automobile.
Fig. 1 is the electronic ignition device for automobile structural representation
Fig. 2 is the cut-away view of ignition mechanism shown in Figure 1
With reference to the accompanying drawings the utility model is described in further detail below:
According to Fig. 1, Fig. 2 as can be known, Darlington switching tube 2 is contained in electronic ignition module metal shell 1 or the metal bottom board slot, be between electronic ignition module metal shell 1 or metal base plate and the electronic ignition module circuit board 5, link to each other with insulating heat-conductive glue 3 between Darlington switching tube 2 and electronic ignition module metal shell 1 or metal base plate, insulating heat-conductive glue 3 has guaranteed that Darlington switching tube 2 contacts well with electronic ignition module metal shell 1 or metal base plate, and play certain fixedly effect of Darlington switching tube 2, if Darlington switching tube 2 bottom surface metals (being collector electrode), then Darlington switching tube 2 must be used the thick mica-sheet insulation of 0.1-0.2mm with electronic ignition module metal shell 1 or metal base plate, its locating stud is also used insulating bush, then with locating stud in little punch press (or using hand hammer) riveted fixing.Metal tablet 4 one side is with insulating heat-conductive glue and electronic ignition module metal shell or metal base plate glue mutually, and another side is also used insulating heat-conductive glue and electronic ignition module circuit board 5 glue mutually, and it acts on the intensity of increase electronic ignition module circuit board 5.Electronic ignition module circuit board 5 is generally based on thick film circuit, and yet available general printed circuit if use printed circuit board (PCB), need not used metal tablet 4.Emitter 6, the collector electrode 7 of electronic ignition module circuit board 5 and Darlington switching tube 2, the welding of base stage 8 usefulness electric soldering iron, corresponding with shell again contact welding.Use transparent vulcanizing silicone rubber 9 embeddings at last, play insulation, moistureproof, antihunt action.
The utility model has the advantages that: simple in structure, cost is low, does not need to adopt bare chip The technology of dress subsides, sintering, lead technology does not take the circuit board plane position, than present state The radiating condition of inside and outside all mounting means is all good, has improved the reliability of electronic ignition device And service life, guarantee rational structure and satisfied the car load requirement, make the Darlington switch Tubular heat directly passes to metal shell or metal base plate sheds, and has improved the Darlington switching tube and has loose Heat condition has reduced the circuit board temperature rise, and Darlington switching tube heat needn't be by circuit board again Pass to shell. Has certain economic benefit.
