Background technique
The diesel engine high-pressure co-rail ejecting system is through the development of more than ten years, and is technical very ripe, the external large batch of already use of diesel engine of vehicle.Because high-pressure common rail injection system jet pressure is very high, fuel injection quantity and injection timing are controlled, are to reduce the most effectively one of means of diesel emission level.Domestic many diesel engines have also adopted the high-pressure common rail injection system, but high-pressure common rail injection system complex structure element precision is high, make difficulty, and particularly electric-controlled fuel injector can only adopt external product so far.The structure of conventional high pressure common rail injector high-speed electro-magnet is as shown in Figure 1; The valve seat 3 that this electromagnet includes the coil 2 on iron core 1, suit and the iron core 1 and is positioned at iron core 1 one ends; Said iron core 1 links to each other with valve seat 3 location through spacing core 4; Cross-under has two wiring terminals 6 on the said valve seat 3; Said valve seat 3 is provided with groove 3.1 towards the one side of iron core 1 around wiring terminal 6, said wiring terminal 6 is provided with through hole and the connection lead of coil 2 is drawn at the end (soldering point 6.1) of wiring terminal 6 away from iron core 1 welds, and groove 3.1 in, pours into fixing glue lead is fixed; The purpose that through hole is set is; After drawing the connection lead; Can in time unnecessary lead be pulled out, preventing that lead from tiing a knot in groove 3.1 twine to cause all kinds of apparatus failures, but owing on wiring terminal 6, carried out drilling through the operation in hole; The weak intensity of wiring terminal 6, and the fuel oil oil leakage phenomenon takes place in soldering point 6.1 places easily.Simultaneously, because the groove 3.1 of valve seat 3 has poured into fixing glue, fixing glue volumetric expansion during high temperature; The power that expands is applied directly on the iron core 1, and iron core 1 has adopted laminated core, and the iron core rigidity of the whole steel part of its ratio of rigidity is a little bit poorer; Thereby make iron core 1 middle outside protruding deformation; Even distortion 0.01-0.02 millimeter also can reduce armature effective travel 20%-40%, fuel injection quantity is reduced.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, provide a kind of good seal performance and iron core when high temperature, to have the high pressure common rail injector high-speed electro-magnet of ability of anti-deformation.
The objective of the invention is to realize like this: a kind of high pressure common rail injector high-speed electro-magnet; The valve seat that said electromagnet includes the coil on iron core, suit and the iron core and is positioned at iron core one end, cross-under has two wiring terminals on the said valve seat, and said valve seat surface is provided with groove to the one side of iron core around wiring terminal; Be provided with dividing plate between said iron core and the valve seat; Said valve seat surface is provided with arc groove between two grooves of the one side of dividing plate, this arc groove is connected two grooves, and the end towards dividing plate on the said wiring terminal has the hole; The connection lead of said coil passes behind the dividing plate in the patchhole, and said connection lead places in groove and the arc groove.
High pressure common rail injector high-speed electro-magnet of the present invention is provided with fixing glue in said groove and the arc groove.
High pressure common rail injector high-speed electro-magnet of the present invention, said iron core are laminated core.
High pressure common rail injector high-speed electro-magnet of the present invention, said Kong Weiyi blind hole.
High pressure common rail injector high-speed electro-magnet of the present invention, said connection wire sleeve is loaded in the wire sleeve.
High pressure common rail injector high-speed electro-magnet of the present invention, the material of said wire sleeve are high temperature resistant material.
Compared with prior art, the invention has the beneficial effects as follows:
High pressure common rail injector high-speed electro-magnet of the present invention; Owing to increase guard screen between valve seat and the iron core; When making the fixing glue of curing be heated volumetric expansion, directly do not contact, still add the expansive force of some special affixs when reducing high temperature simultaneously again in the fixing glue with iron core; The masterpiece that fixing glue expand to produce during high temperature is used on the guard screen, do not affact on the laminated core, thus laminated core distortion when preventing high temperature; On wiring terminal, offer simultaneously one do not run through wiring terminal the hole, improved the bulk strength of wiring terminal greatly, the hole is not for running through the blind hole of wiring terminal simultaneously; Thereby eliminated the leakage of oil point; Improved sealability, on the improved while valve seat of pairs of posts, increased arc groove, made that unnecessary connection lead can be contained in arc groove and the groove easily when installing; Prevent unnecessary connection lead tangled up and knotted, increased the security appliance performance.
