Thereby, the connection reliability of the inducer and the high voltage terminal can be greatly improved, and the normal transmission of high voltage and the stable working of automobile engines can be ensured.
Description
Technical field
The present invention relates to a kind of HV Terminal with metal film.
Background technology
The connected mode of HV Terminal and flow deflector is extremely important to the operate as normal of automobile engine, and flow deflector is connected with secondary coil, and HV Terminal and ignition lead connect joins; High-voltage transmission through flow deflector and being connected of HV Terminal produce secondary coil is given ignition lead; The normal transmission of high pressure can guarantee that the igniting on the automobile engine is stable, reliable, makes engine always work in optimum state, if both connect unusually; Can make product inside flashing (being partial discharge) occur; The product electric property is descended, finally cause the product electromagnetic interference to increase EMC characteristic variation.
At present, generally be designed to elastic piece structure to flow deflector, the registration interface designs of HV Terminal and flow deflector is a smooth surface; As shown in Figure 1, utilize the elasticity of flow deflector 10 self, flow deflector 10 is pressed on the HV Terminal 11; Make flow deflector 10 and HV Terminal 11 can keep being connected; During work, high pressure is passed to HV Terminal from coil windings, outwards output.
But above-mentioned connected mode not only designing and calculating is complicated, and reliability is not high.Because the flow deflector of spring-piece type is to put or face contacts during with the actual cooperation of HV Terminal, contact area is little, therefore; Need the raw-material elasticity modification of detailed calculated in the design, forbidden if calculate, the product later stage has the situation of joining disengagement (as shown in Figure 2; Produced the gap between flow deflector 10 and the HV Terminal 11); And can therefore cause the coil inside discharge, and then cause the production functional test bad, product self electromagnetic interference performance descends.In addition, this connected mode is also higher to the material requirements of flow deflector, need select elastic material for use; Simultaneously; Also need increase other production technologies such as welding, bending to flow deflector, not only increased cost, and complicated production technology also possibly have influence on performance of products.
Summary of the invention
The technical problem that the present invention will solve provides a kind of HV Terminal with metal film, and it can improve the reliability that is connected with flow deflector.
For solving the problems of the technologies described above, the HV Terminal of band metal film of the present invention comprises:
One metal film is riveted on the periphery of HV Terminal near flow deflector one end, and has claw on this metal film;
One mating surface, in be trapped in the HV Terminal, the internal face of this mating surface and metal film and HV Terminal surrounds a cavity jointly.
The HV Terminal of band metal film of the present invention; With the registration interface designs of HV Terminal and flow deflector is sunk structure; And on mating surface, cover layer of metal film, and clamp flow deflector by the claw structure on the metal film, make flow deflector keep tight, stable contact with the mating surface of HV Terminal; Thereby improved the connection reliability of flow deflector and HV Terminal greatly, guaranteed the steady operation of the normal transmission and the automobile engine of high pressure.

Embodiment
Understand for technology contents of the present invention, characteristics and effect being had more specifically, combine illustrated execution mode at present, details are as follows:
Like Fig. 3, shown in 4, the HV Terminal of the band metal film of one embodiment of the invention comprises:
One metal film 212, this metal film 212 is riveted on the periphery of HV Terminal near flow deflector one end, and has claw 213 on this metal film 212, and is as shown in Figure 4 in the present embodiment, and claw 213 is for being cross four paws structure;
One mating surface 211; In be trapped in the HV Terminal, be used for contacting, and inner at this HV Terminal with flow deflector; Part between mating surface 211 and the metal film 212 is an engraved structure, and promptly mating surface 211 surrounds a cavity 214 jointly with the internal face of metal film 212 and HV Terminal.
This metal film 212 is copper alloy or aluminum alloy material, also can select the processing of other metals or alloy material for use, because aluminum alloy material is softer, the electric conductivity of copper alloy is more excellent, and therefore, comparatively speaking, copper alloy is more suitable for the material as metal film 212.
The thickness of metal film 212 is about 0.1 millimeter.Because metal film 212 is blocked up, can increase the difficulty of processing and the material cost of claw 213 structures, thin excessively; Can reduce the intensity of metal film 212 and the clamping dynamics of 213 pairs of flow deflectors 20 of claw again; Therefore, the thickness of metal film 212 generally is no more than 1 millimeter, and is optimum thickness with 0.1 millimeter.
The fit system of this HV Terminal and flow deflector, see also shown in Figure 5, during work; Flow deflector 20 stretches into cavity 214 inside through the claw 213 on the metal film 212, contacts with mating surface 211; Simultaneously, 213 pairs of flow deflectors of claw 20 produce clamping action, make flow deflector 20 remain tight the contact with mating surface 211; Realize that flow deflector 20 is stable with HV Terminal, fastening being connected; The high pressure that secondary coil produces can normally, stably be transferred to HV Terminal through the flow deflector that is connected with coil, and finally is transferred to ignition lead, makes the work of automobile engine normal and stable ground.
Fig. 6 is the metal film structures sketch map of another embodiment of the present invention; As shown in the drawing; Offered the claw 313 of eight pawl types on the metal film 312, the clamping dynamics of 313 pairs of flow deflectors of this claw is bigger, thereby can guarantee more effectively that flow deflector contacts with the tight of mating surface.In addition, claw can also adopt two pawls or six pawl type structures, and still, comparatively speaking, the claw structure of two pawl types and the fiting effect of flow deflector are relatively poor.
In sum, the HV Terminal of band metal film of the present invention designs through the claw on the metal film; Make the fit system of HV Terminal and flow deflector, be improved as the multiple spot contact, not only increased the area of contact by common single-point contact; The clearance issues that has existed when also having avoided conventional high-tension terminal and flow deflector cooperating makes flow deflector more closely reliable with cooperating of HV Terminal, simultaneously; Flow deflector also needn't adopt elastic piece structure again, thereby also can reduce the manufacturing technique requirent of flow deflector.
