Definitions
- the invention relates to a high-current contact device, in particular for motor vehicles, consisting of a cable receiving part on which a high current-carrying cable can be mechanically connected to a cable guide rail and a contact fastening part for attachment to a contact point arranged on an insulating support, the cable receiving part and the contact fastening part being electrically and mechanically are connected to each other via a contact connecting part.
- High-current contact devices are known for many applications, which connect a cable carrying high current to a printed circuit board.
- the high-current contact device is a rigid part, at one end of which the cable receiving part is connected via a riveted connection to a cable guide rail which fixes the position of the cable. At the other end, the high-current contact device is soldered to a conductor track of a circuit board. The mechanical stabilization of the cable as well as the power transmission takes place via this rigid metal part.
- the vibrations of the vehicle are transmitted to the contact during driving. Since strong tensile forces act on the cable due to its cross-section, the solder joint between the contact and the conductor track is subjected to high mechanical loads, which can lead to tearing. This effect is increased by the fact that the metal is heated by the transmission of the load current.
- the invention is therefore based on the object of specifying a high-current contact device which ensures reliable electrical contacting in spite of vibrations to be recorded.
- the object is achieved in that the contact connection part has at least one opening.
- the advantage of the invention is that such contact is insensitive to vibrations. Mechanical and thermal tensions are absorbed and compensated. In particular, the transverse elasticity of the device is increased. In addition, the surface of the contact connection part is increased by the slotted design and thus an improved heat dissipation to the environment is guaranteed.
- the opening extends along the direction of connection of the contact fastening part and the cable receiving part.
- the length of the contact connection part is greater than the distance to be bridged between the cable receiving part and the contact fastening part, adaptation to the available installation space and the problem-free absorption of the vibrations that occur are possible.
- the cable connecting part is resilient.
- the longitudinal forces acting along the contact connection part are compensated for by the buckling spring-like design. This applies both to the tensile forces of the cable and to the joining forces by means of which the cable is fastened to the cable guide rail during assembly. Thus, no mechanical forces are transferred to the contact point on the conductor track and the contact is reliably prevented from coming off.
- the contact connection part has at least one loop-like shape in the form of a compensating arch.
- This shape is approximately perpendicular to the direction of connection between the cable receiving part and the contact fastening part.
- the formation is advantageously arranged between the cable receiving part and the contact fastening part.
- the formation has at least one leg, which is formed parallel to the cable receiving part.
- Such a contact is particularly suitable for mechanical joining.
- the cable receiving part, the contact fastening part and the contact connecting part are formed in one piece as a stamped and bent part in a simple embodiment.
- the cable receiving part and the cable guide rail are advantageously connected to one another via a riveted connection.
- the contact can be so firmly attached to the cable guide rail without fear that torques are transmitted that stress the contact point.
- the heating of the screw connection which is attributable to the transmitted high current strengths likewise does not have a disadvantageous effect on the contact point.
- FIG. 1 high-current contact device according to the prior art
- FIG. 2 basic structure of the one-piece high-current contact device according to the invention
- FIG. 3 side view of the high-current contact device according to the invention
- FIG. 4 high-current contact device in the installed state
- Figure 5 Top view of the high-current contact device according to the invention.
- a high-current contact device as shown schematically in FIG. 1, is known from the prior art.
- a metal part 1 which is simply cranked at each end has a cable receiving part 2 with an opening 3.
- a cable 4 carrying high current which is known to have a large conductor cross section, is attached to one by means of a screw 5 Cable guide rail 6 attached.
- the cable guide rail 6 serves to fix the cable 4 in its position.
- the cable receiving part 2 has a socket 9 with an internal thread, which is riveted to the cable receiving part 2 in the opening 3.
- the socket 9 has an anti-rotation protection 7 integrated on it.
- the guide rail 6 is constructed in such a way that it encloses the socket 9, but there is always a minimal distance as play to these components, which results in their loose fit in the cable guide rail 6.
- the contact has a contact fastening part 10, which is soldered to a conductor track 14 on the printed circuit board 11 via a solder joint 15.
- the lever forces exerted on the cable receiving part 2 and originating from the cable 4 are approximately 10 to 40 N.
- FIG. 2 shows a stamped and bent part for the high-current contact device according to the invention.
- the metal part consists of the cable receiving part 2 with the opening 3, which can be bent by preferably 90 ° around the bending edge A and a contact fastening part 10, which is also bent by 90 ° around the bending edge B in the opposite direction.
- the cable receiving part 2 and the contact fixing part 10 are formed at the respective ends of the metal part.
- a cable connecting part 12 connects the cable receiving part 2 with the contact fastening part 10 to one another.
- the connecting part 12 absorbs forces acting in the horizontal direction via the slots 13 and compensates them. Rotational effects caused by the relative displacement of the printed circuit board 11 and the cable receiving part 2 or the cable guide rail 6 can also be compensated for in this way.
- the width of the contact fastening part 2 corresponds to the width of the connecting part 12.
- the connecting part 12 can also be made narrower than the width of the contact receiving part 2.
- Figure 3 shows schematically the stamped and bent part in the installed state in a side view.
- the high-current cable 4 is led through the opening 3 of the cable receiving part 2 Screw 5 is fastened to the cable guide rail 6 with the socket 9.
- the connection of the cable receiving part 2 and the socket 9 with the cable guide rail 6 takes place in the manufacture of the cable guide rail 6 by overmolding the cable receiving part 2 and socket 9 with an electrical insulator, preferably made of plastic.
- the resilient effect of the connecting part 12 is additionally achieved in the special embodiment by bending the connecting part 12, which, as can be seen from FIG. 3, represents a U rotated counterclockwise by 90 °.
- the two legs 16, 17 are guided parallel to one another, the legs also being arranged parallel to the cable receiving part 2.
- the connecting part 12 absorbs the longitudinal forces acting in the vertical direction (arrow direction) and compensates for them.
- This version is a particularly space-saving variant, since the U-shaped loop of the connecting part can be positioned well below the cable guide rail 6, which reduces the design of the contact and makes it more compact.
- this loop is designed approximately C-shaped or like an open O.
- Figure 4 shows the high-current contact device according to the invention in the installed state.
- the cable 4 is connected to the contact-receiving part 2 via a pole shoe 4a and the screw 5.
- the cable receiving part 2 is fastened to a housing 9, the printed circuit board 11, on which the high-current contact device is connected to the contact fastening part 10, also being arranged in the housing 9.
- the circuit board 11 carries components, not shown, which before forming a hybrid circuit together.
- the contact fastening part 10 is advantageously soldered together with these components in one operation on the printed circuit board.
- Such a high-current contact device is used in an electrical pump control unit for power steering in a motor vehicle.
- solder joint is now elastically decoupled in all axes relative to the cable screwing point.
- the slots divide the cross-section into narrow webs and thus become cross-elastic.
- FIG. 5b shows a view rotated by 90 ° with respect to the arrangement in FIG. 5a.
- the partially slotted leg of the U-shaped bend can be seen starting from the fastening part 10.
- the connecting part 12 is made of copper in order to conduct the high currents.
- the contact is thus attached directly to the guide rail 6.
