Description

The present invention relates to a holding arrangement for at least two electrical connection members, such as e.g. Cable lugs, each having an electrical connection section and a line section.

Furthermore, the present invention relates to a mounting device for equipping such a holding arrangement and a method for establishing a ground contact between a ground pin, which is joined to a support such as a metal sheet, and at least one cable lug. The method for establishing the ground contact should preferably be carried out using a holding arrangement of the type mentioned above.

In general, the present invention is concerned with the field of so-called ground contacts, as they are often used in particular in automotive technology. To establish a stable ground contact, a bolt or a nut is welded onto a metal sheet of a vehicle body, so that the bolt or the nut is electrically conductively connected to the metal sheet. Subsequently, a connection part such as a cable lug is electrically connected to the bolt or to the mother by a nut is turned on the bolt or a screw is screwed into the nut.

It is often necessary to attach a plurality of cable lugs to a ground bolt. The case required installation effort is relatively large. Furthermore, there is a risk that a cable lug of a cable harness supplied by a cable harness manufacturer will be forgotten during the final assembly on the ground bolt. It is known from the prior art to combine the cable lugs of a cable harness, which are to be contacted with a single ground bolt, in a holding arrangement already during the production of the cable harness. For example, the document discloses EP 0 895 305 A1 Such a holding arrangement, which has a cylindrical cage and in the cage by means of a spring axially biased pressure element. The cable lugs are inserted between an axial inside of the cage and the pressure plate from above obliquely, such that the line sections of the cable lugs protrude from radial openings. However, the production of such a holding arrangement is relatively expensive.

The document DE 10 2004 054 782 B3 suggests a mounting preparation for mounting lugs on a bolt. The installation preparation includes a distributor, in which connection lugs of the cable lugs are inserted. Furthermore, a mounting aid is temporarily connected to the manifold, which has a projecting centering. The centering corresponds in cross section to the cross section of the ground bolt and thereby centered the cable lugs by the centering penetrates the connection openings of the cable lugs. When mounting this holding assembly to the ground bolt mounting aid is ejected by the bolt and is then discarded.

Against the above background, it is the object of the invention to provide an improved support structure for connection members such as cable lugs, an improved mounting device for such a holding arrangement and an improved method for establishing a ground contact between a ground bolt and at least one cable lug.

The object is achieved on the one hand by a holding arrangement according to claim 1 for at least two electrical connection members, such. Cable lugs, each having an electrical connection portion and a line portion having a base and a lid portion which is connectable to the base to a holding device, wherein the terminal portions inserted axially in the holding means and axially fixed and the line sections in the radial direction opposite Radial openings of the holding device extend, wherein the radial openings are formed so that the terminal portions can not be pulled out of the radial openings, wherein on the base part and / or the cover part further comprises an axial opening is formed, via which at least one terminal portion of the inserted terminal portions is electrically contacted, wherein the holding device has centering means for centering the connection sections in the holding device and wherein the centering means engage on the outer circumference of the connection sections.

The above object is further achieved by a mounting device according to claim 14 for equipping such a holding arrangement, with a centering bolt on which the base is placed in the axial direction, and with positioning means, by cooperating with a positioning of the base a positionally correct rotational position of the base in Ensure respect to the centering bolt, and wherein the mounting device has anti-rotation means which prevent rotation of the base part with respect to the centering bolt.

1. a) Bereitstellen eines Grundteiles und axiales Einlegen des Kabelschuhs in das Grundteil;
2. b) Schließen des Grundteiles mittels eines Deckelteiles, derart, dass der Kabelschuh verliersicher in der so gebildeten Halteeinrichtung aufgenommen ist;
3. c) Aufsetzen der Halteeinrichtung auf den Massebolzen, wobei der Massebolzen Axialöffnungen in dem Grundteil und dem Decketeil sowie eine hiermit ausgerichtete Anschlussöffnung des Kabelschuhs durchdringt und der Kabelschuh den Massebolzen elektrisch kontaktiert; und
4. d) Aufschrauben einer Mutter auf den Massebolzen, wobei die Mutter den Kabelschuh oder einen darüber angeordneten weiteren Kabelschuh elektrisch kontaktiert und wobei die Halteeinrichtung an dem so gebildeten Massekontakt verbleibt.

Furthermore, the above object is achieved by a method for establishing a ground contact between a ground stud, which is joined to a support such as a metal sheet, and at least one cable lug, according to claim 15, with the steps:

1. a) providing a base and axial insertion of the cable lug in the base;
2. b) closing the base part by means of a cover part, such that the cable lug is captively received in the holding device thus formed;
3. c) placing the holding device on the ground bolt, wherein the ground bolt penetrates axial openings in the base part and the cover part and a connection opening of the cable shoe aligned therewith and the cable lug electrically contacts the ground bolt; and
4. d) screwing a nut onto the ground bolt, wherein the nut electrically contacts the cable lug or a further cable lug arranged above it and wherein the retaining device remains on the ground contact thus formed.

The holding arrangement according to the invention has the advantage that the terminal portions of the terminal members held captively in the holding device are centered by centering means which engage on the outer circumference of the terminal sections. Therefore, a centering on a disposable part is not necessary. Rather, it is possible that the holding device remains after the establishment of the ground contact to the ground contact. As a result, no waste products of assembly.

The base part and the cover part can, for example, be made of plastic and therefore inexpensive.

According to a preferred embodiment, the terminal portions are each formed as flat tongues (such as a cable lug), wherein on the base part and / or on the lid part for each tongue, a seat surface is formed. This makes it possible to assign a predetermined axial position to each connection section in the holding device. As a result, it is possible to fix lugs associated with particular functions at the same position within the holder, respectively. This allows, for example, to provide a plurality of different cable strands, wherein the cable lugs whose functions are identical in the cable strands can each be mounted in the same position. Consequently, the cable lugs do not necessarily have to lie directly axially on one another. For example, an electrical ground contact with an upper cable lug can be made via the nut and an electrical ground contact with a lower lug over a flange of a ground bolt, which need not necessarily touch these lugs. Preferably, however, all lugs touch each other in the holding device.

It is particularly advantageous if the seats have axially different heights whose distance corresponds to the thickness of a tongue.

This makes it possible in a simple manner, the cable lugs each assign a defined axial position within the holding device. The axially different heights of the seating surfaces can be realized in particular easily in injection molded parts.

Further, it is advantageous if pressure portions are formed on the other part, which press the tongues in the closed holding device against the seat surfaces.

In this way, the axial position of the respective tongues can be fixed within the holding device, even if only one or less than the maximum number of Anschlußgliedem is inserted into the holding device.

It is advantageous if the Andruckabschnitte have axially different heights, these heights are each adapted to the heights of the associated seats.

Overall, it is also advantageous if the base part and the cover part can be connected to each other only in a certain rotational position relative to one another.

On the one hand, an unambiguous assignment between seating surfaces and pressing sections is possible as a result. On the other hand, it is possible to form markings on the base part and on the cover part, which identify the respective positions of specific lugs, for example by forming numbers or the like. Accordingly, it can be determined in a simple manner both during assembly and on a finished ground contact, which cable lug is arranged in a specific position of the holding device.

A further preferred embodiment provides that the centering means are designed for at least one connection section on the base part.

In this way, the centering of this connection section can be realized structurally simple. This applies in particular to such a connection section or such connection sections which are inserted first into the base part.

According to a further embodiment, the centering means for at least one connection section are formed on the base part and on the cover part.

In this embodiment, the centering can also be realized low. This applies in particular to upper of a plurality of connecting sections inserted in the base part.

Furthermore, it is advantageous if the centering means have at least one connection section a surface on the inner circumference of the axial opening of the base part. In this case, the axial opening or a section thereof can also fulfill a centering function.

Overall, it is further preferred for the centering means for at least one connection section to have two axially projecting projections on the base part and / or on the cover part, which form the radial opening for the associated line section.

Here, the centering on the outer circumference of the connecting portions is preferably carried out via three contact surfaces or contact points, two of which are formed in the region of the lateral edges of the radial opening. The third contact section for centering can then be formed on a side of the holding device opposite the radial opening.

This may be, for example, a surface on the inner circumference of the axial opening of the base part and / or the cover part.

It is particularly advantageous if the centering means for at least one connecting portion having an axially projecting centering projection on the base part and / or on the cover part, wherein the centering projection arranged on one of the radial opening for the associated line section opposite side of an axial opening of the base or cover part is.

As a result, the contact point of the outer peripheral centering opposing the radial opening may be formed on the base member or on the lid member. The other two contact points are preferably formed for all connection members on the other part (preferably the base part).

According to an overall preferred embodiment, the connection sections each have a connection opening, wherein both the base part and the

Cover part each having an axial opening, which are radially aligned with the connection openings.

In this way, a centering of the connection openings in relation to the axial openings of the cover part and the base part can be realized.

Overall, it is also preferred if the base part and / or the cover part has a Verdrehschutzeinrichtung.

Such Verdrehschutzeinrichtung allows a rotationally fixed positioning of the holding device with respect to the ground bolt, so that rotation of the connecting members when setting up the ground contact is excluded by screwing a nut.

It is particularly advantageous if the anti-rotation device is formed by a deviating from a circular configuration of the inner circumference of the axial opening.

This configuration may in particular be a polygonal shape such as an octagonal shape, in adaptation, for example, to such a polygonal outer periphery of a flange portion of the ground bolt.

Moreover, it is generally preferred if the base part and / or the cover part has a positioning device which allows a clear positioning of the part with respect to a mounting device.

This configuration makes it possible to position the holding device in the assembly with connecting members in a predetermined rotational position with respect to the mounting device, so that a clear assignment of certain cable lugs to certain circumferential positions of the holding device is possible.

It is particularly advantageous if the positioning device is formed on a side of the base part facing away from the cover part.

As a result, the positioning can be realized structurally simple, for example. By an eccentrically arranged recess on the underside of the base.

According to an overall preferred embodiment, the base part and / or the cover part has a receptacle into which at least one additional connection element can be inserted from outside the closed holding device.

This embodiment makes it possible in a simple manner to subsequently provide an additional connection element to an already established ground contact. Preferably, the receptacle is therefore formed on the cover part, so that after unscrewing a nut of the ground contact the subsequent insertion of the additional connection member in the receptacle of the holding device and the subsequent re-screwing the nut is possible.

Overall, it is preferred if the base part and the cover part are releasably connected to each other.

In this embodiment, it is possible to make a subsequent assembly of the holding device, in particular if no receptacle for an additional connection member is provided.

According to a further overall preferred embodiment, the base part and the cover part can be connected to one another via latching means.

In this embodiment, the holding device can be closed easily. Special tool is not required.

According to a further overall preferred embodiment, the cover part is formed integrally with the base part, in particular via a film hinge. In this embodiment, the lid part and the base part may be formed of plastic. In addition, it is possible to provide the lid member and the base member as a single component, so that storage costs, etc. are reduced.

Overall, depending on the above-described embodiment, at least one of the following advantages is achieved with the present invention.

This results in a process-safe pre-assembly at the cable harness supplier.

The size of the holding device can be minimized.

It is possible to realize a torsion protection of the holding arrangement in relation to a ground bolt, for example by means of an octagonal configuration of a flange portion of the ground bolt.

The holding device may be designed to accommodate at least five cable lugs, in particular six cable lugs.

The result is a transport-safe pre-assembly. A change in position of the cable lugs is not possible.

In addition, the cable lugs for the purpose of a simple final assembly centered in the holding arrangement.

The transport lock and the centering lock can be realized without a disposable part.

It is understood that the features mentioned above and those yet to be explained below can be used not only in the particular combination given, but also in other combinations or in isolation, without departing from the scope of the present invention.

In Fig. 1 and 2 a first embodiment of a holding arrangement according to the invention is generally designated 10.

The holding arrangement is used to hold one or two cable lugs 12 (in the case shown, two cable lugs) and has a base part 16 and a cover part 18. The base 16 and the lid member 18 are shown in an open condition with the terminals 12a, 12b axially inserted into the base. The base part 16 and the cover part 18 each have an approximately circular outer circumference and form a holding device 20 in the closed state, in which the inserted cable lugs 12 are securely held. The cable lugs 12a, 12b each have a metallic connection tongue 22a, 22b and a line section 26a, 26b adjoining the connection tongue. The line sections 26a, 26b are connected to a first electrical cable 30 and a second electrical cable 32, respectively. The cables 30, 32 may be part of a cable harness.

The base part 16 has a first seat surface 34a on which the connection tongue 22a rests flatly. Correspondingly, the base part 16 has a projection projecting around the height of the connection tongue 22a, the upper side of which forms a second seating surface 34b.

Furthermore, in front of a base surface of the base part 16, there are a plurality of axial projections 38. The axial projections 38 define a first radial opening 40a for the first cable lug 12a and a second radial opening 40b for the second cable lug 12b.

Furthermore, the holding device 20 formed from the base part 16 and the cover part 18 has centering means 42 for centering at least one of the cable lugs 12a, 12b in the closed holding device 20.

The centering takes place in such a way that central connection openings 46 of the connection tongues 22 are aligned with one another and with an axial opening 44 of the base part 16.

The holding device 20 also has a film hinge 48, via which the base part 16 and the cover part 18 are integrally connected to each other.

On the cover part 18, a first pressure projection 50a and a second pressure projection 50b are provided which have axially different heights. The first pressure projection 50a is formed such that it presses a top of the first connection tongue 22a against the associated seat surface 34a when the holding device 20 is closed. In a corresponding manner, the second pressure projection 50b is designed to press the second connection tongue 22b against the second seat surface 34b.

The height difference between the two pressing projections 50a, 50b corresponds in turn to the thickness of a connecting tongue 22 and is in Fig. 2 shown schematically at 54.

Fig. 2 further shows the folding direction, along which the lid member 18 can be folded about a tangent to the outer periphery of the base 16 arranged axis of the film hinge 48 on the base 16.

On the base part 16 locking projections 58 are also provided, which engage behind an opening of the cover part 18 on the base part 16 an upper side of the cover part 18 latching.

The dimensions of the latching projections 58 are adapted to the dimensions of the pressure projections 50a, 50b and the seat surfaces 34a, 34b, so that in the locked state, the axial position of the connection tabs 22a, 22b is individually determined within the holding device 20. The centering means 42 further ensure that the connection tongues 22a, 22b are centered with respect to the axial opening 44 in the base part 16 and also with respect to an axial opening 60 of the cover part 18 formed concentrically with the axial opening 44.

As a result, when the holding device 20 is closed, a lower cable lug can be electrically contacted via the axial opening 44 in the base part 16. An upper cable lug can be electrically contacted via the axial opening 60 in the cover part 18.

The diameters of the axial openings 44, 60 are consequently larger than the diameter of the connection openings 46 of the connection tongues 22.

Furthermore, in the Fig. 1 and 2 a positioning device 62 in the form of an eccentrically arranged recess on the underside of the base part 16 is shown. By the positioning device 62, it is possible to position the base 16 with a unique rotational position with respect to a mounting device, as will be described below. Furthermore, the inner circumference of the axial opening 44 of the base part 16 is deviating from a circular shape, in the present case in the form of an octagon. However, it is also possible to provide another polygonal surface or another of the circular-deviating inner peripheral surface of the Axialöffz opening 44, such as a toothing or the like. The configuration of the axial opening 44 provides a Verdrehschutzeinrichtung and is preferably adapted to the design of the outer periphery of a flange portion of a ground bolt on which the holding assembly 10 (ie, the holding device 20 with fitted cable lugs 12) can be mounted to form a ground contact. If in the context of the present application is spoken by a ground contact, it is understood that another electrical contact (for example, a positive pole or the like) by means of the holding arrangement 10 according to the invention can be realized.

The holding arrangement 10 is designed to be placed on a ground bolt, wherein the electrical contacting takes place via a nut which is screwed onto the ground bolt. In this case, the mother contacted a top cable lug and the lowest cable lug contacted a flange portion of the ground bolt. The holding device 20 including the base part 16 and the cover part 18 can remain at the ground contact, wherein the nut is screwed through the axial opening 60 in the cover part 18 on the ground bolt, which penetrates the connection openings 46 of the connection tabs 22.

In Fig. 3 a holding arrangement for a further embodiment of a holding arrangement according to the invention is shown in perspective. The holding device 20 corresponds in terms of structure and operation generally the holding device described above Fig. 1 and 2 , In the following, only differences will be explained.

The holding device 20 of the Fig. 3 has distributed over the circumference six seats 34a, ...., 34f, so that the holding assembly 10 can be equipped with a total of six cable lugs 12a, ..., 12 f.

The seats 34a, ..., 34f each have an axially different height, the height gradually increasing in the circumferential direction. Correspondingly, the cover part 18 has six press-on projections 50a,..., 50f, the axial height of which is also different. In this case, the fifth pressing projection 50a corresponds to the deepest seating surface 34a.

Three of the Andruckvorsprünge are designed so that they slightly protrude in the radial direction with respect to the axial opening 60 inwardly. In this case, these Andruckvorsprünge 50a, 50b, 50c are slotted in the longitudinal direction, in order to realize elasticity in the radial direction. Accordingly, when screwed in through the axial opening 60, a nut can push the slightly inwardly projecting pressing projections 50a, 50b, 50c radially outward.

The centering means 42 of the holding device 20 of the Fig. 3 are formed so that each inserted terminal tongue 22 is externally contacted at three points in order to achieve the centering. Two of the abutment sections are each formed by the axial projections 38, between which the radial openings 40 are formed. On the opposite side of the axial opening 44 then a third contact portion is provided for centering. This third abutment portion is formed for the terminal tongues, which are inserted at positions 1, 2, 3, by radial stops 66 a, 66 b, 66 c, which are provided on the inner circumference of the connection opening 44. The radial stops 66d, 66e, 66f for the connection tabs in the positions 4, 5 and 6 are formed by radially inner surfaces of the pressing projections 50a, 50b, 50c.

In Fig. 3 It can also be seen that at least one bolt latching nose 68 projects beyond the inner circumference of the axial opening 44. The Bolzenrastnase 68 is disposed in the region of the underside of the base member 16 and serves to engage behind a flange portion thereof when mounted on a ground or a centering pin. - With -other words, the holding device -20 can be axially fixed by means of the bolt latching nose 68 on a mass or centering pin.

Fig. 4 shows in schematic form a mounting device 70 for mounting a holding device 20. The mounting device 70 has a centering pin 72 which has a similar shape as a welded to a vehicle body ground bolt. The centering pin 72 has a flange portion 73, whose outer circumference is formed as a hexagon or octagon. The circumference of the flange portion 73 thus forms an anti-rotation 74, which is designed to, with the anti-rotation device of the holding device 20 (ie, the inner circumference of the axial opening 44) to engage. Further, between a lower surface of the flange portion 73 and an upper surface of a mounting surface 78, a detent opening 75 is formed, into which the bolt detent tab 68 (or the plurality of bolt detents 68) can engage with detent engagement.

Laterally next to the centering pin 72, a positioning means 76 in the form of a protruding from the mounting surface 78 pin is provided. The positioning 76 engages mounted base 16 in the positioning device 62 on the underside of the base, so that the base 16 can only be fixed in a certain rotational position with respect to the centering pin 72 latching thereto.

The assembly of the holding device 20 of Fig. 3 takes place by means of such a mounting device 70.

In Fig. 5 Here, for example, shown that at the mounting positions 1, 2 and 3 already cable lugs with connection tabs 22a, 22b, 22c have been used.

Fig. 6 shows a further mounting state, in which additionally cable lugs with connection tabs 22d, 22e are used.

While the connection tongues 22a, 22b, 22c can already be centered by means of the base part 16, the intermediate centering of the further connection tongues 22d, 22e takes place by means of the centering pin 72.

In a final assembly step, the lid part 18 is folded onto the base part 16 and latchingly connected thereto to form the closed holding device 20. The cable lugs 12 used are held captive in the holding device 20. Due to the pressure projections of the cover part 18, the upper connection tongues 22d, 22e are now also centered, so that the holding arrangement 10 thus formed can be removed from the centering pin 72.

In the in Fig. 7 shown state, the holding assembly 10 may be connected, for example, with a harness, which can then be delivered together with the support assembly 10 to a final assembly location. During this transport, the cable shoes 12 used in the holding arrangement 10 are held captive and thereby fixed both in the axial direction and in the radial direction, ie centered.

In the final assembly, the holding assembly 10 can then be placed on a ground stud 82, as in Fig. 8 is indicated schematically. The ground bolt 82, which may be formed, for example, on a vehicle body, corresponds in terms of its shape to the centering pin 72. Consequently, the Bolzenrastnase 68, the in Fig. 8 behind the flange portion of the ground bolt, not shown, and first provisionally fixed to the ground bolt. Subsequently, a nut 80 can be screwed onto the ground bolt 82, whose underside contacts the uppermost connection tongue 22b. The underside of the lowest connection tongue 42a is contacted by the upper side of the flange portion of the ground bolt 82.

In Fig. 8 is shown schematically at 84 a sheet metal, to which the ground bolt 82 may be joined, in particular by way of stud welding. The ground bolt 82 preferably has a coarse thread. The centering pin 72 need not have a thread, but may have a thread, as in the FIGS. 5 and 6 is shown.

In the FIGS. 9 and 10 a modified form of a holding device 10 is shown. In this case, the holding device has a cover part 16, which has an axially externally accessible receptacle for an additionally or subsequently to be attached cable lug.

The shape of the receptacle 90 corresponds to the shape of the receptacles for the connection tongues of the cable lugs 12 arranged in the holding device 10

Cover part 18 is further formed an axially upwardly open radial opening 92, via which the line section 26 of the additional cable lug can extend. In the region of the radial opening 92 locking lugs 94 are formed, which can engage behind a line section 26 of an inserted additional cable lug.

Consequently, as can be seen in Fig. 10 is shown, one already on a ground bolt (in Fig. 10 not shown) mounted by inserting an additional cable lug 96 after unscrewing the nut 80 in the receptacle 90. The additional cable lug contacts the uppermost cable lug arranged inside the holding arrangement 10. Subsequently, the nut 80 can be screwed on again to complete the ground contact in this way.
