Definitions
- the invention relates to a method for producing an electrical connection between an aluminum conductor and a contact element, in which an stripped end of the aluminum conductor is inserted into the contact element and electrically contacted with it, and in which a mechanical strain relief of the aluminum conductor is formed by reshaping the contact element in the latter is clamped.
- Such a method can be found in each case from DE 199 02 405 A1 and DE 33 16 563 A1. It is provided here that an aluminum conductor consisting of several tinned stranded wires is first mechanically clamped in a crimp sleeve. After the mechanical clamping, which is done by reshaping the crimp sleeve, the crimp sleeve is soldered or welded to the tinned aluminum conductor.
- Aluminum conductors instead of the otherwise usually provided copper conductors. Insofar as aluminum or copper conductors are referred to here, this means that the conductors largely consist of aluminum / copper or an aluminum / copper alloy. Due to the significantly lower specific weight of aluminum, weight savings can be achieved.
- the invention has for its object to allow easy to manufacture and safe and long-term contact between an aluminum conductor and a contact element with low contact resistance.
- the object is achieved according to the invention by the method according to claim 1. Then a stripped end piece of the aluminum conductor is inserted into the contact element and electrically contacted with it.
- a supply of a contacting means is provided to form the electrical contact, the contacting means being heated at least up to the range of its melting temperature, so that it is preferably in molten form.
- the contacting agent in particular tin or a tin alloy, a material connection is established between the aluminum conductor and the contact element.
- the aluminum conductor is therefore immersed, in particular, in a molten bath of the contacting agent accommodated in the contact element.
- the contacting agent is heated, for example, by irradiation of a high-frequency field, by irradiation of high-energy light (laser light) or directly by a flame or by another heating element.
- the contact element is mechanically deformed during or after the formation of the electrical contact, so that the aluminum conductor is clamped in the contact element in order to form a mechanical strain relief.
- the provision of the liquefied contacting agent and the “immersion” of the usually tinned stranded wires of the aluminum conductor result in good electrical contact between the aluminum conductor and the contact element with low contact resistance.
- the contact element is usually also tinned on its inner surface
- the amount of contacting agent is advantageously the depth of penetration of the contacting agent between the individual stranded wires and thus the contact area to the stranded wires.
- Another decisive advantage is the simultaneous or subsequent reshaping of the contact element.
- the contact element is also heated due to the heated contacting agent, so that reliable forming without material damage and in particular without
- the contact element is formed in a forming zone which is spaced apart from a contacting zone in which the electrical contacting takes place.
- This measure in turn serves to separate the mechanical from the electrical function.
- this has the advantage that the contacting formed before the forming, in particular via tin or a tin alloy, is not impaired by the application of the pressure required for the forming.
- the contacting zone is not exposed to pressure, so that there is no risk of the contacting agent subsequently flowing, as a result of which the electrical contacting could deteriorate.
- the contact element is preferably additionally heated in the forming zone in order to enable a material-saving forming with improved flow behavior compared to a cold forming without crack formation.
- the contacting agent is expediently heated to a maximum of about 280 ° C. This measure prevents damage to the insulation of the aluminum conductor. In addition, the insulation can be protected by special clamps or other protective mechanisms.
- melting is guaranteed at a temperature of 280 ° C, since the melting temperature of tin is around 232 ° C and the melting temperature of a tin alloy with 10% zinc is 198 ° C.
- soldering paste can also be used as the contacting agent, which is in molten form at 280 ° C.
- the solder paste has halogen-free, non-corrosive flux in order to avoid subsequent corrosion of the solder connection.
- the portion to be tinned is shock-heated and then immersed in a tin bath.
- the section is preferably heated to about 400 ° C or more. It is advantageous here if the section is shock-heated in a time of ⁇ 1 second. This rapid heating can be done inductively by irradiation of a high-frequency field or by using a high-energy laser light. The shock heating leads to a different expansion behavior of the aluminum and the oxide layer.
- a protective gas atmosphere is preferably provided.
- the tinning of the section is carried out by ultrasonic tinning in a tin bath.
- ultrasonic tinning takes advantage of the fact that small cavities, so-called cavitations, are created by the irradiation of ultrasound in the tin bath, which collapse explosively. This creates considerable local compressive forces, which lead to damage and chipping of the oxide layer, so that the pure aluminum is in turn largely wetted by the tin.
- the aluminum conductor is immersed in a tin bath and part of the aluminum conductor is cut off or cut off in the tin bath.
- a "fresh" separating or cutting surface is formed by the separation in the tin bath, which is wetted with tin directly and without contact with atmospheric oxygen. This measure ensures that the cutting surface is tin-plated over the entire surface for the longitudinal spreading of the individual stranded wires, the separating surface corresponds to the cross-section, so that there is no reduction in the cross-sectional area in the contacting area with regard to the electrical contact surface is the cross-sectional area.
- the reshaping process takes place within a very short reshaping time, which in the ⁇ s range is in particular in the range up to about 10 ⁇ s.
- the decisive advantage with such rapid forming is that the individual stranded wires of the aluminum conductor behave less like a solid stranded wire than more like a liquid, so that the individual stranded wires bake or fuse together. This effect is comparable to a projectile that pierces a metal plate at high speed. The metal plate does not appear as a solid in the reference system of the projectile. Rather, the projectile penetrates the metal plate like a liquid.
- the inner surface of the contact element is roughened or structured.
- This roughening or structuring additionally deforms and penetrates the oxidation layer of the aluminum conductor during the forming and clamping, so that contact is made in the forming area between the contact element and the aluminum conductor.
- the inner surface of the contact element is provided, for example, with grooves or with threads that are preferably sharp-edged. When forming, these grooves or threads virtually cut into the individual stranded wires. By cutting, an additional mechanical strain relief is formed at the same time. This contacting can take place in addition to the contacting via the contacting means or as an independent contacting.
- the sudden reshaping and the simultaneous formation of the electrical and mechanical connection mean that an automated method, that is to say an automated striking of the contact element on the aluminum conductor, can be implemented at very high clock rates.
- the reshaping takes place by magnetocompression rapid magnetic reshaping.
- magnetocompression are to be reshaped
- Contact element generates very high magnetic fields, so that high currents are induced in the contact element, which in turn form a magnetic field, so that the contact element is repelled and thereby deformed due to the Lorenz force.
- the contact element is preformed, for example, in the manner of a sleeve or slotted sleeve into which the aluminum conductor is inserted.
- the external magnetic field leads to a radially inward deformation of the sleeve, so that the inserted aluminum conductor is clamped.
- the magnetocompression can achieve pressures in the range of, for example, 2000 bar. Since no mechanical forming elements are required, the contact element is not damaged despite these high pressures.
- the sudden reshaping takes place with the aid of a reshaping element by mechanical impact pressing.
- the shaping element expediently strikes the contact element at a speed> 5 m / sec, in particular> 10 m / sec.
- Conventional hydraulic presses do not reach these speeds and are therefore not suitable for sudden forming.
- the speeds for the forming element are in this case preferably generated solely by the weight, that is to say the forming element, for example designed as a mandrel or claw, strikes the contact element to be formed in the manner of a guillotine.
- connection between the aluminum conductor and the contact element is preferably insulated against moisture.
- a shrink tube is drawn on or the connection is coated with an insulating varnish or insulating adhesive.
- FIG. 1 shows a connection between a contact element and an aluminum conductor
- FIG. 2 shows a detail of the contact element with the aluminum conductor to illustrate the magnetocompression
- Fig. 3 is a partial representation of the contact element and the aluminum conductor to illustrate the forming by means of impact pressing and
- Fig. 1 an already finished connection between a contact element consisting in particular of copper and designed as a cable lug and an aluminum conductor 4 is shown.
- the contact element 2 is designed in the manner of a sleeve and has a receiving space into which an stripped end piece 6 of the aluminum conductor 4 is inserted. In the end piece 6, individual stranded wires of the aluminum conductor 4 are exposed. The stranded wires are tinned at least on their end portion.
- a supply or reservoir of a contacting means 8 is provided between the front end of the stranded wires and the rear wall or the base of the contact element 2.
- tin or a tin alloy is provided. The electrical contact is made between the aluminum conductor 4 and the contact element 2 via the tin alloy.
- the inner surface of the contact element 2 is preferably likewise pre-tinned.
- the tin alloy is introduced into the contact element 2 and melted. Subsequently or even before melting, the aluminum conductor 4 with the stripped end piece 6 is inserted into the contact element 2. In particular, the front ends of the stranded wires are immersed in the melted tin alloy 8. After cooling, there is therefore a material connection between the contact element 2 and the individual stranded wires of the aluminum conductor 4. A contacting zone 10 is formed in the region of the contacting means 8 and the front ends of the stranded wires.
- a forming zone 12 is provided spaced apart from the contacting zone 10, within which the contact element 2 is shaped. 1 already shows the deformed state in which a deformed section 14 of the Contact element 2 has penetrated into the stripped end piece 6.
- the aluminum conductor 4 is clamped in the contact element 2, whereby an effective mechanical strain relief is formed.
- the connection region in the exemplary embodiment is still surrounded by a shrink tube 16 as insulation against moisture.
- the contact element 2 is heated at least in the forming zone 12.
- a heating element 18 is provided, which is constructed in two parts in the exemplary embodiment and at the same time also serves to heat the contacting means 8 up to the region of its melting temperature.
- the heating element 18 is subdivided into two functional zones which are designed for the different requirements, namely the heating of the reservoir 8 and the heating of the contact element 2.
- only one heating element 18 can be provided for heating the contacting means 8.
- the contact element 2 is also necessarily heated.
- an ultrasound generator 20 is also provided.
- the contact element is in this case suitably mechanically fixed to an ultrasound sonodrote or acoustically coupled by a transmission medium for the transmission of the required ultrasound energies.
- the shaping process can be carried out in a conventional manner by mechanical or hydraulic pressing of shaping elements against the contact element 2.
- reshaping by means of magnetocompression is provided in the exemplary embodiment according to FIG. 2.
- a very strong magnetic field is generated by magnetic coils 22 in the immediate outer region of the contact element 2, so that currents are induced in the conductive contact element 2 and the Lorenz force is formed. This acts in the direction of the arrows shown in FIG. 2 on the contact element 2 and thereby causes the contact element 2 to be deformed.
- a so-called mechanical impact pressing is provided for reshaping according to the exemplary embodiment according to FIG. 3.
- a forming element 24 is struck against the contact element at a very high speed.
- the shaping element 24 is designed in the form of a spike.
- a counter element 26 is arranged, which in particular can also give shape to the forming process.
- the high speed of the shaping element 24 in the direction of the arrow direction shown in FIG. 3 is preferably achieved solely by acceleration due to gravity.
- a very rapid forming takes place with a duration in the ⁇ s range. Due to the sudden reshaping, the special effect is achieved that the individual stranded wires connect to one another in a materially integral manner.
- the sudden forming processes according to FIGS. 2 and 3 can therefore take place in addition to the mechanical connection for electrical contacting additionally or alternatively to the electrical contacting via the contacting means 8.
- the inner surface of the contacting element 2 is roughened or structured at least in the forming zone 12.
- a thread 28 is cut into the sleeve-like contact element 2. 2 and 3 show the situation before the forming process. After the shaping, the particularly sharp-edged threads of the thread 28 cut into the stranded wires and, in particular, penetrate the oxide layer.
- Process step "I: tinning of aluminum conductor 4" can alternatively be carried out by one of the following sub-processes:
- A conventional tinning or using an aluminum conductor with pre-tinned stranded wires
- Process step "III: Forming the strain relief” is carried out by one of the following sub-processes:
- i conventional forming
- ii Forming by magnetocompression
- iii Forming by impact press.
- the aluminum conductor 4 is first pre-tinned in the stripped section 6 by one of the sub-processes A, B, C or D.
- the sub-processes B, C and D are distinguished by a very good tinning result, so that these sub-processes can also be used as independent tinning processes independently of the electrical contact between the aluminum conductor 4 and the contact element 2.
- the electrical contacting as described for FIG. 1 takes place subsequently to the tinning.
- the individual stranded wires are immersed in a melted reservoir of tin or tin alloy, so that a solid bond between the individual stranded wires and the contact element 2 is formed via the tin after solidification.
- the shaping takes place, in particular according to one of the methods (ii, iii) described for FIGS. 2 or 3.
- process steps II and III can also take place simultaneously, that is to say that the forming does not necessarily have to take place after the melt has cooled.
- the only decisive factor is that the melting does not take place after the forming process.
- process steps I and II are combined with one another in a common work step, that is to say take place simultaneously. Specifically, it is provided that the tinning of the stranded wires takes place with the aid of ultrasonic tinning according to sub-method C, as was described for FIG. 1.
- the process sequence according to FIG. 6 is characterized overall by a one-step process in which process step I, namely tinning of the stranded wires, can be dispensed with.
- process step I namely tinning of the stranded wires
- the electrical contact (II) and the mechanical connection (III) take place within a single process step according to sub-procedure ii or iii.
- This one-stage method for producing the electrical and mechanical connection illustrated with reference to FIG. 6 is particularly suitable for automation with a high clock rate.
