Description
Technical field
The present invention relates to the method that a kind of manufacturing has the moulded parts of integrated conductor strip (conductor run), relate to a kind of method of making the moulded parts of automobile especially, and a kind of moulded parts that uses this method to make.
Background technology
At automotive field, especially in the manned vehicle field, wish to have the short as far as possible repacking time, that is to say the end user place an order and the time gap paid between the automobile from the production site short as much as possible.In order to accomplish this point, the part that offers the production site must prefabricated degree height.For supplier, this means the part of difference configuration with high density of integration, that is to say part, must be in the very short time manufactured come out with difference in functionality.
Aspect the power-supply system of automobile electronic system, many leads are joined together to form a prefabricated electrical power wiring assembly at present.
Summary of the invention
The objective of the invention is to realize flexibly and expense is made moulded parts cheaply, particularly be equipped with the moulded parts that is used for automobile of conductive paths.
According to the present invention, the method for the feature by having claim 1, above-mentioned purpose is achieved.This method provides conductor strip has been applied directly to an installing component, and the installing component of an automobile moulded parts especially is so that this conductor strip is integrated on this installing component.Wherein,
A) surface of installing component is handled selectively according to the profile of conductor strip, so that this surface has the zone of different adhesive ability;
B) growth (germination) layer is used in the profile that offers conductor strip; And
C) conductor strip is applied to grown layer.
In this article, conductor strip specifically refers to be used in the automotive field conductor strip of the electrical power wiring assembly of power-supply system.Moulded parts can be any automotive parts of wanting, and it is used for the setting of the lead-in wire or the electronic component of electrical power wiring assembly.This moulded parts for example is car door, door module, half-blank (panel) or gauge panel zone or the like.This moulded parts can be made up of any required material, for example metal or plastics.This installing component can be identical with moulded parts, maybe can be the part of moulded parts.
This method is not to only limit to automotive field, makes conductor strip but be widely applicable on the part of various technical field.Except being used for automobile power system, this method also can be used for especially making and is used for household electrical appliance and electronic toy, remote control electric automobile for example, conductor strip.
Wherein step a) is based on such idea, on the surface of any required form, flexibly, fast and does not make independently conductor strip structure with causing great expense, and does not need built-inly, and for example, guide groove or other electric conduit are in installing component.Thereby step a) has defined required conductor strip structure.Step b) is based on such idea, provides grown layer or adhesion promoters (adhesion promoter) layer so that conductor strip is bonded on the installing component reliably.Step a) and b) order also can exchange, that is to say that grown layer can at first be employed, for example, still, be bonded on the whole surface so at first equably by using conducting powder in big area.Then, the surface of installing component is by local melting, for example by selectable heat treatment, so that the grown layer powder is bonded in these zones securely.For this variation, installing component is made up of plastics or is preferably had a coating or a frosting, for example varnish or an adhesion agent.
Best metallic growth layer also can be considered to be in the adhesion promoters layer between installing component surface and the conductor strip.This allows the conductor strip figure to be manufactured on reliably on the installing component of being made up of various different materials, and does not have the danger of disengaging.Thus, in step c) conductor strip by good bonding be applied to installing component.
This new mode makes required conductor strip figure be fabricated directly on the installing component, optionally is installed on the installing component of any required form and shape.There is no need manually to go between for each lead and electrical power wiring assembly.In fact, Gao Du automation can realize.In principle, this method allows the whole power-supply system of automobile to be formed by quick, flexible and expense cheaply, makes that manufacturing is not possible with the automobile power system of lead.Do not have installing component direct integrated of projecting member to make conductor strip be employed and be protected from mechanical loss well, for example bitten by rodent.
In the step after step a), the zone that is used for conductor strip can selectively form to sticking.Perhaps, if large-area bonding substrate is arranged, for example a kind of suitable clear coat finish, all the other regional adhesion properties that are not used in conductor strip can reduce.Conductor strip preferably utilizes line heat/power adhering method or injection method to use.Said line heat/power adhering method is often referred to such method, particle beam, and promptly used material is in particular the copper particle, utilizes kinetic energy to be drawn towards installing component after heat is provided.So method is also referred to as thermal spraying usually, described in DIN 32530.Mask, electromagnetic field or the thing that is called as overcoat stream (sheathed flow) can be formed to be used for bonding in as far as possible objective mode.The particle that said " heat " here should be considered to refer in particular in the particle beam is softening, and begin and will melt, fusing, perhaps they are heated at least and make the surface of installing component produce the degree of thermal distortion.This thermal distortion comprises the reduction of superficial hardness, and is softening, or the surface begins and will melt.Said " power " should be understood that enough high the making of the momentum of particle partly is pressed into the surface at least when they arrive the surface, and this surface may be softening in advance with quilt.
So-called bluster is sprayed (gas flame spraying) and is especially suitable for use as adhering method.In this injection method, the conductor strip material that use is specially copper, is partly melted at least in course of injection.The heat that is applied is flux growth layer at least in part preferably, makes that grown layer and conductor strip material closely and are preferably integrally linked together.The bed thickness of conductor strip can be by selecting suitable nozzle parameter or by spraying the twice above method in this surface, forming suitable thickness according to the requirement with sufficiently high conductivity water temperature and depth.Bluster spray to allow very fast and bonding conductor strip economically, has relatively little technology effort.
Except bluster was sprayed, so-called cryogenic gas sprayed (cold gas spraying) and also is fit to.This method is also referred to as line plating (beam plating).In this method, particle is with very high kinetic energy bump installation surface.In this case, some particles are accelerated to velocity of sound, even faster.The diameter of particle, copper particle for example is in the scope between 10 μ m and 100 μ m for example.Cryogenic gas sprays and makes material be used under high speed.Because high kinetic energy, low relatively temperature is enough, makes on installing component and the blasting materials, that is to say that on the particle, thermal load is low.Generally, high injection rate and high bonding efficient are possible, and thick layer can be used.
Adopt heat/power adhering method, be in particular bluster and spray, a major advantage that forms conductor strip is a high flexibility, even because can make any required conductor strip structure by spray technology on the moulded parts of complexity.And the conductor strip structure can be made apace.And spray technology has such advantage, and chemical can be handled and particularly not use to installing component selectively.In order optionally to handle, line preferably utilizes mask, electromagnetism line or crust stream to aim at specific point.In order to make complicated conductor strip structure as quickly as possible, plural instrument or injector head are preferably with the operation simultaneously abreast each other of grid arrangement mode.
In this adhering method, particle is usually by the vector gas load, and vector gas is preferably for example unreactable gas of nitrogen.This makes the dangerous low of undesirable particulate oxidation, so the conductor strip of manufacturing has high conductivity.
Except conductive particle, nonconducting impurity, especially silicon are joined in the particle line easily in addition.These impurity, it preferably accounts for 0.01% to 1.6% of weight, has favorable influence for the conductivity water temperature and depth of conductor strip, does not change its mechanical characteristics.
As substituting of heat/power adhering method, conductor strip also can be applied to formed grown layer by other method in principle.Especially, installing component can utilize the material that only bonds to grown layer and the conductor strip of formation to be pulled by a molten bath.
Bonding for utilizing liquation, fluent material also can use with wave soldering (wave soldering) form.In addition, conductor strip also can utilize the adhering method of conducting resinl, conductive powder or lamination process to use.When utilizing the bonding conductor strip of conductive powder, be provided with powder particle to such an extent that as much as possible closely be important, to realize enough conductivity water temperature and depth.In order to improve conductivity water temperature and depth, conductor strip preferably is heated in that dusting is last, so that each particle is toasted in the mode of sintering process each other.Especially, passed through conductor strip for big electric current of this purpose.All methods have common feature, and promptly used conductive material only is used for the zone of conductor strip structure, thereby form the conductor strip of wanting.
In a preferred embodiment, this method step a) is to c) at least two be implemented by processing unit (plant), thereby allow the conductor strip structure to get at high speed and create economically.For this purpose, processing unit (plant) has, and for example, thermal source is to change the adhesion property on surface by heat treatment.Simultaneously, one provides the copper particle to be integrated into this device with the unit that forms grown layer.The three, one injector head also can be integrated simultaneously to make conductor strip.Perhaps, grown layer and conductor strip can be made by injector head.
Claim 7 provides many favourable selections to change adhesion property after step a).Preferred improve design according to one, installing component scribbles a material, its can being crosslinked (cross link) and the crosslinked action of its adhesion property by subsequently change.Especially, neoprene (elastomer) can be as this material that can be crosslinked.The example of this class is rubber coating or silicone (silicone).For bonding grown layer rubber coating bonds to uncrosslinked zone.
Substitute as one, the material that preferably provides for example curable (cure) of epoxy resin, polyurethane (polyurethane) or cyanoacrylate (cyanoacrylate) for this purpose is as surface material.And, also can use stupalith, the advantage of stupalith is their heat-resisting ability.Therefore they are particularly suitable for being used to lead wire in the zone that has the harsh temperatures load and bring to sensor, for example in the position near combustion chamber or brake.
In a further advantageous embodiment, adhesion property is changed by coating chemically reactive substance on surface material.For example, this chemically reactive substance is used to crosslinking Treatment can be by chemically sensitized surface material, for example the rubber coating of Shi Heing.Perhaps, also may provide a solvent, for example be used as the chemically reactive substance that is used for frosting.Frosting for example is one to be used for the overlay of installing component of metal or pottery.
In another preferably substituted, adhesion property was changed by heat treatment, particularly by thermal radiation or electromagnetic radiation.Especially, surface material is through laser treatment.One halogen radiating element preferably has 50 to 70 watts power, also can be used to produce thermal radiation.In this case, lens or baffle plate (shutter) are used to focus on.It is favourable using two or more radiating elements simultaneously.The surface, particularly frosting of the softening a little installing component of this heat treatment.For example, copper powder then is applied to these surf zones that softened to form grown layer.The radiation operation makes surface material processed very fast with flexible, and has high spatial resolution.As substituting of the radiation of using radiant, heat also can be introduced by flame or hot gas.
Adhesion property also can be by directly applying an adhesive linkage to the surface and change in a kind of mode easily selectively.For example use an overlay or an adhesive linkage for this reason.Adhesion property at this overlay also can be affected by introducing heat.In this case, the coated technique of selection only provides overlay on the mounting material in the zone of the conductor strip profile of wanting based on such idea, rather than on whole surface.This causes the saving of material and cost.In this case, when adhesive linkage is applied in, according to step b) provide coating to grown layer so that it forms, for example contain coating as the metallic particles of the adhesion promoters of conductor strip by use.
According to another advantageous variant, surface material is charged to make bonding conductor strip structure by electromagnetism.The material that is fit to, for example the stone mill powder is applied to the charged conductor strip structure of electromagnetism, as is known the method in the laser printing field subsequently.
According to the condition of installing component, form the adhesion property of the installing component that offers the zone that is independent of the conductor strip structure of wanting, especially on big area, by changing a kind of special surface material of adhesion property selectively.For example this surface material uses by coated technique.In the distribution of big area top surface, on the whole erection parts, make and to make any conductor strip structure of wanting flexibly and economically especially.For this reason, the adhesion property of surface material only changes at the conductor strip contour area of wanting.Therefore the conductor strip profile only just was defined before using actual conductor strip, and did not relate to the action of any complexity, for example built-in guide groove in installing component.
Grown layer preferably adopts one of described selection of claim 8 to implement.Grown layer is also referred to as the accelerator layer, and guarantee conductor strip good bond to installing component.
Especially, provide copper powders may to be applied to the surface of installing component.For example those not bonding surf zones are eliminated by apply then on a large scale.Powder also can use by tubule especially, for example follows radiant closely, as the halogen radiating element, is provided with afterwards, changes adhesion property thus.And installing component also can be soaked a powder pond.At this, for example powder is pressed by powder circulation frequent in the powder pond with by powder is oscillated on the installing component.As another method for optimizing, use a metal suspension (suspension) to installing component.This metal suspension comprises the metallic particles that is distributed in the fluid.The material that this fluid was evaporated or was mounted parts sponges, and metallic particles bonds on the installing component selectively.Nozzle or pin (pin) that this bonding process for example utilizes draught machine to use are implemented.
Grown layer preferably self was conduction originally.In principle, non-metal and nonconducting grown layer also can be used, as long as it is suitable as the adhesion promoters layer of the enforcement that is used for conductor strip subsequently.
Grown layer preferably has in offering the profile of conductor strip (profile) and has interruption.Grown layer is not to be applied to whole conductor strip zone with this, but regional area only.At this, grown layer can have shadow character, diamond features, honeycomb structure or blob features.In interruptive area, conductor strip can not bond on the installing component.These non-bonding regions are connected by conductor strip bridge shape.This requirement is used to the compensation of length or tolerance (tolerance), that is to say, for example compensates the conductor strip that different thermal expansion coefficient causes and the difference of the length between the installing component, and conductor strip is not damaged.Generally, this method makes the conductor strip structure have elasticity.
Conductor strip preferably is applied on the layer of compensation at least in part, and this layer of compensation is connected to installing component in a kind of unfixed (floating) mode, only that is to say loosely to connect.The unsteady installation that the layer of compensation of conductor strip is installed be used to compensate in installing component or two installing components between transitional region produce the tolerance level of the position of torsional stress or shearing stress.On installing component, float to install layer of compensation make issuable stress not be sent to or only not half be sent to conductor strip, so conductor strip is only born slight load and can not damaged.For example, layer of compensation forms by the rubber coating that is fit to, and this rubber coating is broken away from from installing component after crosslinked operation.Adjacent with layer of compensation, conductor strip be applied to one with the close-connected layer of installing component on, for example epoxy resin layer perhaps is applied directly on the installing component.
In order to improve conductivity water temperature and depth, an advantageous method changes the material structure of mounted conductor strip.For example, the conductor strip heat treatment by adopting laser especially or realize this point by exerting pressure.
Another coating is coated on the mounted conductor strip easily.This randomly or ordinatedly is used to increase conductivity water temperature and depth or as preventing the protective cover that corrodes or as insulating protective layer.For example a kind of " PU " material or rubber are applied to conductor strip as the corrosion protection layer.But conductor strip self also can be made up of corrosion resistant material, for example tin bronze alloys.This benefit is that conductor strip can be made into directly to be connected with any position of wanting.
Especially after using conductive material, the material and/or the impurity that have too much used are got rid of at an easy rate by cleaning process.For this reason, installing component for example utilizes liquid or pressurized air to handle in cleaning.Perhaps, for example can use the mechanical cleaning method of brush or laser treatment.
In order to realize reliable and permanent connection the between conductor strip and the installing component that the bonding force of conductor strip is increased by a technique for fixing that is fit to.In the variation of the embodiment that uses rubber coating, the method for realization is that the conductor strip zone that initial Non-crosslinked is handled is crosslinked processing by vulcanization.Vulcanization herein preferably adopts heat treatment to finish, and this heat treatment is together carried out when using conductive layer, for example by using hot copper powder.
In order to obtain high as far as possible functional density, conductor strip or plural conductor strip are employed so that the electric function element is manufactured.This for example is cond, coil or resistance.Conductor strip forms with the geometric configuration that is fit to for this reason.For example, the cross-sectional plane of conductor strip changes so that produce specific resistance.In order to form the cond with suitable electric capacity, appropriate capacity area determined by conductor strip or by the specific subregion (subarea) of conductor strip, and conductor strip by appropriate lead-in wire to form a coil.Conductor strip or can be the form of shielding.Functional element preferably also is the sensor of safety relevant (safety-relevant).For example, the capacitance variations of the cond that is formed by conductor strip is used to outside car body panel zone, as the indication of distortion, and then triggers air bag.
In a special preferred improvement, two or more conductor strip are configured to the mode of one deck on another layer.This makes that on the one hand desired space is little, can form electric function element, for example cond simultaneously.
If complicated conductor strip figure must guarantee to avoid the danger of arc discharge carefully, adopt suitable conductor strip lead-in wire especially, that is to say mode by how much.For the 42V power-supply system in the automotive field, the danger that arc discharge occurs is a special factor.Following method is provided for this situation especially:
-conductor strip has sufficient interval each other, especially at critical area.Therefore their adopt wide size of mesh opening to form, and particularly in the zone of those more possible arc discharges, for example at contact area, yet narrow mesh region is formed on hazard free zone.
-at least one additional conductor strip is set between the conductor strip that has difference of potential each other, and is used to sensor, for example is used to occur temperature build-up and then produces electric arc.
-be arranged on conductor strip between the conductor strip that has difference of potential each other and be the part of circuit (disconnection circuit) of taking out stitches, thereby corresponding conductor strip can be disconnected from power line voltage when electric arc occurring.
-if 3-dimensional multi-layered structure, wherein two-layer or more multi-layered conductor strip is configured to the mode of one deck on another layer, and conductor strip is not only in two dimension but also at three-dimensionally formed suitable size of mesh opening.Stagger each other and realize by conductor strip is set especially, so that superincumbent conductor strip is set in place on the insulating tape between two following conductor strip.
-contact point is formed and is arranged in a zigzag or serration, so that creepage (creepage) distance between two contact points is long as far as possible, simultaneously, it is as much as possible little that the contact point grid keeps.
In an advantageous embodiments, the large tracts of land conductive layer is formed, and is arranged in the layer, and is the part of power-supply system, and is the different function of automobile power system execution.Conductive layer is configured to one deck on another layer, and parallel installing component extends.This embodiment variation is based on so idea, allows to adopt large-area conductive layer to contact with electronic component regardless of their position.For example, in fact the power line voltage of electronic component can output to any position of wanting from each conductive layer.Herein, each conductive layer is that automobile power system is carried out various functions.Especially, two conductive layers are in different current potentials, and other layer is used to data bus.
As long as conductive layer is set on the installing component, these conductive layers conductor strip of each definition and conductor strip structure cover the corresponding big area as one deck so.Also can merge the conductive layer that these are arranged on the corresponding plain conductor band in the layer, that is to say that each conductor strip does not cover a big area.Conductive layer is preferably the form of electric function element, and for example cond or sensor are in the mode identical with single conductor strip.
In order to make the conductor strip on the moulded parts be connected to other automobile power system, for example connect by inserting, in a simple manner, it is not to be connected to installing component fully that a preferred exploitation provides conductor strip, but can break or leave from it at a certain subregion.This preferably realizes by application one isolated component or an isolation layer below conductor strip.Perhaps, fritter conductor strip zone is so handled and is made that linking being bonded in this subregion of installing component is broken away from.For example this can finish by the heat treatment of rubber coating.In order can partly to disconnect, preferably different surface material is broken away from from installing component in order to make a kind of in the surface material, for example through after the processing that makes by side by side setting each other in conductor strip zone.In another preferably improved, before conductor strip was applied to installing component, conductor strip was extended to form a kind of lead-in wire (pigtail).This lead-in wire for example is used to transmit the remainder of electrical power wiring assembly from the car door zone to auto body.
In order easily to be electrically connected with connecting wire, an end of this lead preferably places on the conductor strip structural region and is electrically connected to conductor strip, when the latter forms subsequently.Because connecting wire is coated in conductor strip, between connecting wire and conductor strip, form directly whole the connection herein.There is no need to carry out subsequently any welding sequence.If conductor strip is used under heat effect, there is no need so insulating barrier is peeled off from the end of connecting wire.In fact, insulating barrier will be destroyed by the application of conductor strip.
Connect in order to obtain failure-free, the end of connecting wire is that suitable shape also connects big as far as possible zone to form the bonding pad in this case.For example, utilize bevelled surface or accomplish this point by formation wedge shape (dovetail), triangle or flexuose shape.In this case, the end of lead bevel (bevel) or have the lug (1ug) that adheres at an easy rate.Alternatively or additionally, wire end preferably is formed with groove or hole, for example by punching press.In a word, can adopt this applying method to come to form between two traditional leads for conductor strip and connect, the end of lead is preferably suitable shape for this reason.
In order to form the connection lug, the present invention preferably provides an inserted mode system part with the cooperation installing component, and is covered or coating by a conductor strip at least in part subsequently.This inserted mode system part is made of metal or plastics as insertion parts, for example has the profile of plug pin or jack.This profile is covered by conductor strip.What do for the connecting wire band is required is that the plug of assembling one pairing of adopting respective design is to this connection plug.
In a word, this makes plug system made, and wherein the shape of each connection plug, orientation and size of mesh opening in fact can be according to desired selections of suitable shape of inserted mode system part.Especially, this make form self-locking and can not become possibility by the connection of incorrect link and coding.
Though be used, be connected the connection that also can be used between part fixed mount or the circuit fixed mount with the direct integral body of conductor strip, perhaps be used to connect electronics package, for example motor, loud speaker etc.In this case, the present invention provides being connected of conductor strip and circuit fixed mount, for example printed circuit board (PCB) or circuit anchor fitting especially.By loading a contact member, for example one contact pin (contactpin), in circuit fixed mount or circuit anchor fitting, conductor strip is connected with this contact pin.Each circuit is fixing in the circuit anchor fitting is interconnected with one another by the contact pin.At this, that connected nail is designed to continuous conduction or have insulating regions, and also can be the form of contact hole.Replace the contact pin, also can use contact hole, perhaps can use contact disc, and by force together each other.
In the application of conductor strip,, connect also and can perhaps connect or other connection by forming on the conductor strip that is pressed in formation by forming insulation-displacement (insulation-displacement) terminal as the bonded assembly alternative method.
In one was preferably improved one's methods, the lead that forms by the method by line coating brought and forms and being connected of electronic component.Herein, this element for example is arranged on the printed circuit board (PCB).This method can replace welding or conductive adhesive operation, and these operations are used to form and being connected of element at present usually.
At automotive field, often must connect electric wire to element, door panel for example is so that electric wire is connected to control unit operator's compartment inside or the machinery space from car door.In order easily to transmit conductor strip, easily form conductor strip and be connected with Connection Element formation in both sides.In this case, conductor strip easily is directly connected to Connection Element again in the process of using.
Because element often is divided into He Gan district, wet district, Connection Element is easy to pass the feasible formation sealing of element.Connection Element is the form of metal rivet for this reason, for example, and is embedded in the nonconducting element, forms sealing with this.This method has avoided being provided with necessity of sleeve pipe (grommet), forms as tradition when electric wire passes this element.If this element be conduction and metallo-particularly, Connection Element preferably is insulated layer and surrounds so, for example a rubber cradle.
For make conductor strip be applied to simple method in addition the moulded parts of dielectric load how much on, a particularly advantageous improvement design at first provides conductor strip to be applied to installing component and also changes over the desirable net shape of moulded parts subsequently by a formation operation, for example by thermoforming for this reason.Thereby installing component is preferably semi-finished form, itself or profile flat fully or that insulated and formed in advance.Before one formed operation, the application of conductor strip allowed above-mentioned method to implement in a simple mode, for example had the zone of little radius in protection (fender) zone or at other.
In this case, conductor strip easily has in the formation zone of installing component and has the electrology characteristic of wanting after such size makes conductor strip form operation.For example, conductor strip is forming the zone than the bigger thickness of other zone use.This has prevented the cracking of conductor strip in forming the operation process, for example in the thermoforming process, and guarantees that conductor strip finally has enough thickness.The thickness of layer is easy to and applies coupling.At automotive field, the thickness of used layer typically is between the 20 μ m to 1mm.
In an easy improvement design, conductor strip is applied to the surface of a moulded parts that prolongs, for example electric wire, flexible pipe, pipe, conduit.This moulded parts for general extension provides many structures to select, and these moulded parts can have additional function.For example, the outside face of cable, particularly foamed plastic (foamed-in-place) cable can be coated with conductor strip up hill and dale, so that provide shielding by this conductor strip.In this case, this coating preferably utilizes two or more spraying nipples that are arranged side by side each other to apply.
As this a alternative, for two or more discontinuous conductor strip that will form, the route of those conductor strip is parallel to each other, and this structure is preferably manufactured.These also can be set at the flexible pipe or the inside face of pipe (tube) or conduit (pipe), for example are used for the conduit (conduit) that building is installed, and are electrically connected so that also produce by empty supravasal conductor strip simultaneously.
To have had the moulded parts of conductor strip integrated in order producing economically, at low cost, to have made required material usage as much as possible little normally favourable.This particularly realizes by the following method:
-select grid (grid) size of the little grown layer that is used for two or more conductor strip, so that in spray process, select the skin area of high conductor strip and the ratio on the surface that is covered.
-preferably, conductor strip is combined in the path (corridor), and corresponding to the width of employed beam in the spray process, perhaps the width of the width of described beam and described path is complementary the width of conductor strip basically.In order to accomplish this point, purpose for example in order to assemble, the particle beam is surrounded by shell beam (sheathing beam).This method is used for noise reduction simultaneously.
If-two or more nozzles or fog-spray nozzle are used to spray process, they are provided with in a kind of suitable mode, and switch individually particularly.
-too much coating material, particularly copper powder utilizes a cleaning technology to be removed, and is supplied to a disposal system so that utilize again.
-for the content of the oxide components that makes undesirable copper is low, for example utilize in spray art that the unreactable gas of nitrogen forms required environment, for example adopt shell beam or transmission beam.
The modified example of present embodiment, it does not directly adopt based on this new mode as the step a to c of this method that claim 1 limited and makes conductor strip, particularly, also can be used in principle utilize other method to make conductor strip except the claim 1 as the described modified example of claim 9 to 24.
This target also can adopt described method to realize by the moulded parts with conductor strip, and this conductor strip is applied to installing component and integrally is connected with it.The advantage of this method of having described and preferred improvement project also can convert moulded parts on equivalence.

The specific embodiment
At first, be described in the basic step of making conductor strip 10 on the installing component 4 by example and referring to figs. 1A to 1C.Installing component 4 has superficial layer 5, and superficial layer 5 is looked the material of installing component 4 and formed the applicability of bonding region 5A, be applied directly on the surface of installing component 4 or in extra method step as superficial layer independently.As example, superficial layer 5 is a coating.In the first step shown in Figure 1A, superficial layer 5 is handled selectively, so that change the viscosity of described superficial layer, and then at treated zone formation bonding region 5A.For this purpose, be provided with the irradiation system 7 that comprises irradiation source 7A and be used for convergent beam path 7C especially.Irradiation source 7A is laser or halide torch.This irradiation source is used to introduce heat and melted surface layer 5A.
In second step shown in Figure 1B, copper powder 28 is applied to bonding region 5A especially by means of supply pipe 9, and be manufactured into be bonded in the there.The copper powder 28 that is applied is used as the grown layer that is used for conductor strip 10, and described conductor strip 10 will be employed (as Fig. 1 C) in next step.For conductor strip 10 is bonded on the installing component 4 well, grown layer 26 is used as the adhesion promoters layer.Therefore grown layer 26 is called as the accelerator layer hereinafter.Preceding two steps also can be exchanged, and make powder 28 at first be applied, and superficial layer 5 just just are melted after this.In this case, the introducing of heat also can cause favourable oven dry effect or fusing effect simultaneously, and makes the powder particle leak-tight joint.
In third step, by injection method, particularly by the bluster gunite, conductor strip 10 is applied in subsequently.For the bluster gunite, applied material, particularly copper are heated in the nozzle 98 of injector head, and by partial melting at least, perhaps are made into to begin fusing.In this case, copper particularly is provided for injector head as powder, and the particles of powder size can cover the scope from about 5 μ m to several millimeters broads.The speed of particle and can reach velocity of sound in the scope of per second number meter, particularly for the cryogenic gas gunite.In this case, particle is injected on the installing component 4 with the form of the particle beam 82 that carried by the inertia current-carrying gas.Baffle plate 98A is provided for and assembles particle beam 82.In order to make conductor strip 10, described injector head moves relative to installing component 4, and the speed that moves in this process is in the scope of several meters of per seconds (for example 2～10m/s) or the faster speed that can obtain.
It is that permission is applied to the conductor strip structure of complexity on the installing component 4 very apace that bluster is sprayed the major advantage that has, and particularly can adopt the mode of automation.This make to replace complicated manually lay each cable for automobile power system and becoming possibility.In addition, in fact installing component 4 can have any desirable structure.Thereby the bluster injection also is applicable to the described grown layer of manufacturing.
Fig. 2 to Fig. 6 has shown the various modified examples of the manufacturing of the moulded parts of the complexity with installing component 4 and described conductor strip.Described moulded parts and integrated conductor strip are made with a plurality of method steps usually.In this case, manufacturing process can be subdivided into following key step, and these steps can partly adopt, and adopts selectively or combines employing:
Method step A: the provision of making the unstable subregion (loose subarea) of described conductor strip;
Method step B: use insulating barrier;
Method step C: use conductive plane;
Method step D: application surface material;
Method step E:, handle described surface material in order to change viscosity;
Method step F: use the accelerator layer;
Method step G: use described conductor strip;
Method step H: clean or fixation procedure; And
Method step I: use protective cover.
Each figure has mentioned that the alphabetical A that represents described each method step is to I and shown which kind of method step of different modified examples for moulded parts has been used.
Fig. 2 has only shown the square part of the moulded parts 2A with multiple-structure.Isolation layer 6 and conductive plane 8 alternately repeat on installing component 4 each other.In shown three conductive planes 8 altogether last limited by an isolation layer 6, and two other isolation layer 6A and 6B are applied to this isolation layer, and two or more in addition conductor strip 10 are applied to described two isolation layer 6A and 6B.This multiple-structure is finished by protective cover 12 at the top.
Method step D to G particularly is used to use conductor strip 10.Conductor strip 10 has the discrete profile of extension.On the contrary, conductive plane 8 has big area and without any the preferred direction that forms.Thereby they form conductor strip as continuous plane.In fact, can be connected with each conductive plane 8 in any desirable position.
Therefore multiple-structure shown in Figure 2 has been represented the combination of the layout of discontinuous conductor strip figure and large tracts of land conductive plane 8, and described discontinuous conductor strip figure is 6A by isolation and 6B represents.The modified example of discontinuous conductor strip figure will be explained with reference to Fig. 2 and Fig. 3 especially in more detail, and the modified example of conductive plane 8 will be explained with reference to Fig. 4 and Fig. 5 especially in more detail.
As shown in Figure 2, installing component 4 also has isolation layer 14 at one jiao, and this isolation layer 14 is applied in by method step A.The described multiple-structure that this isolation layer 14 allows to be applied to installing component 4 is partly removed.Thereby the subregion 16 of described multiple-structure is by insecure ground rather than be connected to installing component 4 securely.This unstable subregion 16 utilizes the angle that is upturned of each layer that is applied to installing component 4 to represent.The structure of unstable subregion 16 will be explained with reference to Fig. 3 and Figure 10 especially in more detail.
As shown in Figure 3, the operation that is used to make the moulded parts 2B with discontinuous conductor strip structure is as follows: at first isolated location 18 is applied to installing component 4, for example is applied to the panel of arrangements for automotive doors, and just part covers installing component 4 (method step A).Perhaps, also can apply isolation layer 14.Installing component 4 and isolated location 18 adopt surface material coated subsequently.Especially, rubber coating 20 is used as surface material (method step D).Surface material is shone in method step E subsequently selectively, that is to say a kind of partial restriction mode.In this case, adopt laser as irradiation source especially.Irradiation causes rubber cross (crosslinking), and forms and now only have low-viscosity crosslinked surf zone 21, and rubber is not to be in crosslinked state at first in rubber coating 20.Those not irradiated zones still have the discontinuity zone of each formation conductor strip structure 22 in original high viscosity and those zones, and the profile of conductor strip structure 22 is corresponding to the desirable profile of the conductor strip 10 that will apply.
In ensuing method step F, grown layer or accelerator layer 26 are applied to each conductor strip structure 22.This process comprises two stages.At F/s, the powder of being made up of conductive material 28 is applied simultaneously the zone in crosslinked surf zone 21 and those uncrosslinked conductor strip structures 22.Powder 28 for example is a copper powder.Powder 28 bonds to conductor strip structure 22.Unnecessary powder 28 is got rid of (method step H) from producing crosslinked residual surface zone 21 in cleaning process.This process is for example finished by utilizing pressurized air to blow powder off.The zone of those conductor strip structures 22 that are not crosslinked as yet is crosslinked (being similarly method step H) by for example thermal-radiating technique for fixing.This has improved the bonding effect of powder 28 for rubber coating 20, and has therefore improved the bonding effect for installing component 4.Formed accelerator layer 26 is used as the adhesion promoters between installing component 4 and the conductor strip 10.
In ensuing method step G, actual conductor strip 10 is applied to accelerator layer 26.This step preferably adopts the bluster injection or for example adopts wave soldering to apply conductive material from melt and finish.As a replacement scheme of this step, the gluing that also exists possible method to apply to have conductive material or from gas or plasma, apply conductive material.In addition, conductor strip 10 can adopt the mode of lamination process to be formed conducting strip (strip).Unnecessary conductive material can utilize cleaning process to be removed subsequently equally.
Because copper powder at first is distributed on the conductor strip structure 22 in described exemplary embodiment, conduct electricity so be called as the layer of accelerator layer 26.But, because a large amount of granule boundaries and accelerator layer are only with the extremely thin fact, so a problem of Chan Shenging is that conductivity can only be low in this case.In an alternative modified example, because the heat affecting between the single powder particle, the conductivity of powder particle increases by oven dry, makes accelerator layer 26 self become the form of conductor strip 10.Usually, in order to increase conductivity, utilize conductive material band 10 to be applied in addition.In principle, those methods that apply conductor strip 10 are equally applicable to this purpose.
In isolated location 18, the structure that forms with the method is just placed on the installing component 4 insecurely, that is to say that it is not to be connected to securely on the installing component 4.Thereby subregion 16 can be got rid of from installing component 4.Because subregion 16 can be inserted into plug simply, this unstable subregion 16 is particularly suitable for, and for example, utilizes plug to form contact.
Formed structure optimization ground is compressed under pressure, particularly in order to improve bonding between each layer.
The structure of moulded parts 2C shown in Figure 4 is based in essence to be carried out and the identical step of step that is used for moulded parts 2B shown in Figure 3.On the contrary, the conductor strip 10 on the moulded parts 2C shown in Figure 4 is configured to one deck on another layer in a plurality of layers.Thereby moulded parts 2C is characterised in that the multiple-structure of discontinuous conductor strip 10.
Because discontinuous conductor strip 10 is configured to one deck now on another layer in a plurality of layers, so the multiple-structure of moulded parts 2C is different from multiple-structure shown in Figure 2.On the contrary, the multiple-structure shown in the moulded parts 2A among Fig. 2 has a succession of discontinuous conductor strip figure between isolation layer, conductive plane 8 and isolation layer 6A, 6B.In a word, be arranged to one deck on another layer and two isolation layer 6A, 6B with discontinuous conductor strip figure have the multiple-structure that can compare with the multiple-structure of moulded parts 2C shown in Figure 4.
Described multiple-structure causes three-dimensional conductor strip figure.In this case, in order to make more complicated wiring figure, some independent conductor strip 10 can be connected to each other by cross connection 30.
This three-dimensional structure is formed to G by apply conductor strip 10 back repetition methods step B in first plane.This means that applying conductor strip 10 back rubber coatings 20 in first plane is applied again.If want the conductor strip 10 in two continuous levels is joined to one another, so between described two conductor strip, for example between cross connection 30 and the conductor strip below it 10, rubber coating 20 is removed again in the contact area, perhaps utilizes mask to prevent the coating of this rubber coating 20.
Whole multiple-structure protected seam 12 surrounds.This preferably both had been used to isolate purpose and also had been used to prevent the purpose of corroding, and was preferably the layer of being made up of polyurethane (PU) material.
This multiple-structure preferably extends on whole moulded parts 2D.One as this structure substitutes, and also can only cover the subregion of this layer structure.In addition, different subregion also can have and is isolated from each other and layer structure that structure is different.Essential characteristic is applied to not exist on the installing component 4 any preferential direction in large area for each conductive plane.In principle, this improvement allows to make connection in all positions of moulded parts 2D.Because in fact electronic component can be positioned at according to desirable mode on the moulded parts 2D, so this allows to control very neatly and locate the bonded assembly electronic component of wanting.And, because not every electronic component all is provided with their power lead, so shown layer structure allows very compactness and the structure that makes full use of the space.This has lot of advantages, particularly in the gauge panel zone that must connect a large amount of electronic components, because a spot of free space in there is not blocked by a large amount of cables and attaching parts.
Because very large area has been guaranteed enough conductivity, so the large area region of conductive plane 8 means that they can form thinlyyer than discontinuous conductor strip 10.
Be provided with contact window 32 in some layers in each layer 6,8,12, and contact window 32 concentrates in the contact area 34, so that be connected with each conductive plane 8.In this case, contact window 32 is so arranged, and makes each conductive plane 8 cooresponding contact pin 36 can pass (Fig. 5 B).In this case, in case formed contact, each contact pin 36 has tangent mating surfaces 38 on their lower surface that places on the conductive plane 8 separately.For the conductive plane 8 of appointment, the contact window 32 that is associated with the conductive plane 8 of this appointment under any circumstance all is set in all layers 6,8,9 that are arranged on this plane 8.Therefore the number of the contact window 32 that is arranged side by side each other increases on the direction up of pointing to protective cover 12.Described protective cover 12 has 4 contact window 32 altogether.
Preferably, a plurality of contact areas 34 are set on the surface of moulded parts 2D, make each conductive plane 8 to form with a lot of positions via contact pin 36 and are connected.In this case, contact area 34 can be configured to be distributed on the described surface according to desired, is connected with electronic component formation in any desirable position so that allow.
As a kind of variant of the structure that is positioned at the contact pin with tangent mating surfaces 38 36 on the described end face, contact rod 40 is provided, shown in Fig. 6 B.This has two or more contact areas 42, contact area 42 along it length distribution and utilize area of isolation 44 and be isolated from each other.This alternating structure that area of isolation 44 and contact area are 42 is corresponding to the alternating structure of moulded parts 2E shown in Fig. 6 A.Each contact area 42 and power lead 46, and by power lead, for example, be connected with electronic component formation.For forming the contact rod 40 that contacts with each conductive plane 8, it is preferably insulation-displacement contact rod, and this contact rod utilizes a kind of " punching " method to be driven in the layer structure of moulded parts 2E.In order so to do, described contact rod is equipped with edge of a knife (not shown) in its lower end 48.In this case, each contact area 42 forms with each conductive plane 8 and is connected.Because contact rod 40 is tightly clamped by each conductive plane 8, so should " punching " method have the advantage of high contact reliability.Utilizing this method also may form with any ideal position of moulded parts 2E is connected.As a variant of this method, contact window 32 is provided for contact rod 40 equally, and by contact window 32, contact rod 40 is pushed in this multiple-structure.
Another kind is used to provide the modification of the ability that forms contact, promptly by means of contact plug 56, shown in Fig. 7 A and Fig. 7 B.Contact plug 56 explained with reference to discontinuous conductor strip figure, yet it is applicable to too to form with smooth conductive plane 8 and is connected.
