Description
Technical field
First conductive component that the present invention relates to be used for to have flexible wire form wiry is connected to the method for the second conducting metal assembly (for example, second electric wire or Connection Element).
Background technology
Purpose is to make electric wire from the battery to the starter in advance reduce to lay the installation cost of these lines largely in motor vehicle.On the one hand, these electric wires are made as the length of appointment, and on the other hand, they are designed to have curve and/or crooked to simplify its laying in this respect clearly on their route.In order to realize so pre-making, these lines must have corresponding rigidity, are designed at electric wire that this can realize under the situation of the wire of (one-piece) bonding jumper of monoblock or monoblock or rod.
Yet, although,, be about to the line segment that these electric wires are designed to have flexibility so there is such requirement because such electric wire also must comprise the regional of flexibility or the option that length compares is carried out in necessary existence because their are made in advance.
Because its low relatively cost, such line is preferably made of aluminum.
Based on its cost performance of comparing with copper, even for the line in the application outside auto industry, aluminium also is favourable.One during these are used is in lift control technology field.In the case, use flat line, it is used as being connected between static distribution panelboard and the elevator cab in elevator shaft.Use such line, then the tensile strength of this line must be suitable for lift conveyer (conveyor) highly.Surpass a certain conveyer height, common line just must be reinforced with the textile cords (fabric cord) or the load-carrying unit of steel wire rope form.Especially true for those lines made of aluminum, because aluminium has low relatively tensile strength.For this reason, knownly use the wire of making by chromium-nickel alloy to reinforce made of aluminum and have a large amount of those lines wiry.
For the flexible wire that has been designed second conductive component (for example, rigid wires is arranged or Connection Element is arranged), require these two parts are linked together, must avoid as much as possible thus being connected the contact resistance that the tie point place produces by this.
Known fetching by electric resistance welding is connected to each other the rigid metal assembly.This is possible, because these two rigid metal assemblies are caused tight contact and can be connected to each other by the welding that the latter's electric current is flow through in use.Therefore, can not fetch by electric resistance welding and be connected to the rigid metal assembly, the wire of flexible wire be contacted in the needed mode of resistance welded with stiff member because can not be under pressure with being designed a large amount of flexible wires wiry.
Summary of the invention
Therefore, the purpose of this invention is to provide a kind of method,, have a large amount of flexible wires wiry and also can be connected to second metal assembly, for example the metallic conductor of monoblock or Connection Element by resistance welded by this method.
Realized this purpose according to the present invention, wherein the free end of flexible wire is inserted in the sleeve pipe and with the latter and pushes, and in addition that end that is assigned to flexible wire of second conductive component is inserted in the free end of sleeve pipe and and contacts with flexible wire, and electric current flows through this two assemblies, the end that they rely on each other by this electric current is melted in together, and sleeve pipe is made by such metal, and this metal has will be by the higher fusing point of the metal of assembly connected to one another than these two.
Preferably, during current flowing (channeling), under pressure, make these two electric assemblies contact.
Preferably, conducting metal second assembly is formed by electric wire, and this electric wire has to be shaped as strip, bar-shaped or thread electric conductor and to be connected to and has a large amount of flexible wires wiry.Equally, second conductive component can be formed by Connection Element, and this Connection Element is connected to has a large amount of flexible wires wiry.In the case, can be designed as die mould (profiling) shape towards that face of second assembly of first assembly, thereby preferably this die mould is designed to trellis (waffle) figure.In addition, flexible wire can have a large amount of wires made of aluminum, and it uses the wire of being made by chromium-nickel alloy to reinforce.In the case, these two conductive components can be made of aluminum, be made of copper, by brass make or by aluminium with can make by the wire that chromium-nickel alloy is made.Sleeve pipe also can be made by steel plate.
In case these two conductive components are welded together, just preferably inciting somebody to action particularly, the insulator of shrink film form is applied on the tie point.
