Description

The invention relates to a cable connector for producing a mechanical and electrical connection between at least two cables, comprising a housing having a wall, an internal cavity and at least one opening and a cable harness with at least two cables connected to one another via such a cable connector and a method for connecting at least two cables.

Connections are known in which, in the cables to be connected, the wires are exposed and directly connected to each other, e.g. by twisting them together. In addition, the wires can still be soldered together or

be welded, so that a Aufdrillen and detachment is prevented.

Another method is to insert the cable ends from either side into a tube or tube and then tighten the tube or tube around the two cables. For this purpose, a pipe or a cut piece of tubing is preferably made of a soft metal and is crimped, ie with a device or pliers transversely to the longitudinal axis so squeezed and permanently deformed that it clamps the inserted cables and fixed together, wherein the electrical connection is made via the contacting wires. Instead of a soft metal, the tube may also be made of a plastic material which contracts under the influence of heat and also permanently contracts the cables fixed to one another, a so-called heat-shrinkable tube.

As moisture protection or for sealing, it is usually still necessary to embed such compounds separately again in a protective cover or the o.g.

Combine techniques with materials for sealing.

DE 37 25 124 A1 discloses a method for producing water or

steam-tight cladding of wire harnesses for motor vehicles, in which the cable to be connected are inserted into a shrink tube or cap and the assembly is finally filled with a plastic and foamed. The disadvantage of this is the complicated production.

From DE 10 2009 042 385 A1 a connector device known for electrically connecting a conductor to a circuit board by means of direct insertion of the

Plug device in a contact hole of the circuit board. The production of

moisture-proof wire harnesses is not shown here.

From DE 20 2015 105 849 U1 a distributor connection is known with a 2-part insulating housing, in the wall of the housing integrated pushbuttons, front and rear openings for insertion of cables, 2 metal contact units for receiving the inserted into the openings cable and a circuit board for Assigning the inlets and outlets. The arrangement shown is not suitable for harnesses, since first the contact units must be connected to the circuit board, used together in the lower housing part and the upper housing part must be placed and mounted. Thereafter, the cables are inserted through the openings by pressing the push buttons in the contact units and clamped. The disadvantage of this is the complex assembly and in particular the provision special

Contact units. A tightness is not provided here because of the push buttons. DE 600 27 953 T2 discloses a watertight connector for electrical

Connection contacts, consisting of a connection housing with a front and a rear end and a rear end and a plurality of

Cavities for receiving connection contacts. The connector also has at least one bus bar installed on the terminal housing on the front end, whereby the bus bar protrudes into the cavities to make contact with the terminal contacts located in the cavities. A seal is made via a cap installed at the front end of the housing and a sealing member at the rear end of the housing. It is more in a plug connection with a plug and a socket. The disadvantage here is the complex and complex design, especially in the projecting into the cavities busbar.

Figure 1 shows an example of a simple cable connection of the prior art. To make a connection, the cables are twisted together at their ends, that is wound around each other. The ends are partially stripped and the wires exposed, so that the wires partially abut each other and an electrically conductive connection is made. However, this connection is mechanically not very resilient. Therefore, the veins are improving

Connection usually additionally soldered or welded together. A further improvement is represented in FIG. 2. The cables twisted together are aligned parallel to the actual course of the cable, and the cables connected to one another are embedded in an enclosure so that the

Joint is located completely within the shell. Thus, the joint is electrically isolated using a corresponding material. If the ends of the plastically deformable sheath are then pressed together, the cables introduced into the sheath are clamped to the openings of the sheath and mechanically fixed.

In Figure 3, a sheath made of a shrink tube is used, wherein the

interconnected cables are guided only by one side of the hose. Due to the thermal induced shrinkage of the shell, the cables are connected to one another in a mechanically loadable manner and the connection point is electrically insulated toward the outside.

FIG. 4 shows an exploded perspective view of a device according to the invention

Cable connector 1. This comprises a housing 10, one of the housing 10th

enclosed cavity 11 and an opening 12 in the housing 10 for accessing the cavity 11th In the illustrated embodiment, the housing 10 has a round cross-section and is overall cylindrical. In principle, however, all cross-sectional shapes are suitable which form a sufficiently large, coherent cavity, that is also a triangular or polygonal cross-section.

The inner wall of the housing 10 is provided with ribs 13. These stiffen the wall and the housing 10 is dimensionally stable. At least one rib 13 is provided. In the exemplary embodiment, the housing 10 is shown with 3 ribs 13. These are arranged in the same angular pitch W to each other.

Inserted in the cavity 11 are a connecting element 30 and a shaped body 20. The connecting element 30 is first introduced into the cavity 11 and

then the shaped body 20, so that the end face 21 o of the shaped body 20 of the opening 12 faces.

The molded body 20 has from one end face 21 o to the other end face 21 u

Bushings 24 for the cable 40 on. For stiffening and later mechanical Fixing the respectively provided for connection ends of the cable 40 are each equipped with a contact element 50.

These contact elements 50 are inserted at the end face 21 o in the passages 24 of the molding 20 and passed through the molding 20 to the other end face 21 u. In this case, the contact elements 50 occur on the other side of the

Shaped body 20 so far out that they engage with the tips in corresponding holes 31 of the connecting element 30.

Since the connecting element 30 itself is electrically conductive or at least electrically conductive, the cables 40 connected via the connecting element 30 are connected to one another in an electrically conductive manner. Here in the embodiment, 3 cables are electrically connected to each other. However, only 2 cables or even more than 3 cables can be connected to each other.

In a further embodiment, the shaped body 20 and the

Connecting element 30 integrally formed, e.g. be glued together (not shown).

Fig. 5 shows the shaped body 20 and the connecting element in a longitudinal section. The bushing 24 is for receiving the cable or the contact element 50

intended. The bushing has a stop 25, which limits the insertion movement of the cable 40 or the contact element 50 and thus a certain

End position defined. It is envisaged that the cables 40 could be manually plugged into the contact elements 50 instead of being press-fitted by machine or with fixtures. Since there are then no sufficient holding forces by a pressure, a separate lock is necessary. For this purpose, in the implementation each side locking strips 26 are arranged for the fixation or locking a in its end position, i. inserted to the stop 25

Contact element 50 (Fig. 10). The locking strips 26 do not extend over the entire length of the implementation, but end within this and each form an edge 27 spaced from the stop 25.

FIGS. 6 and 7 respectively show plan views of the molded body 20 (FIG. 6) and of the connecting element 30 (FIG. 7). Shaped body 20 and connecting element 30 are aligned with each other so that the bushings 24 and the correspondingly associated bores 31 are each in alignment, so that a plugged through a bushing 24 contact element 50 engage with its tip in a corresponding bore 31 of the connecting element 30 and can be pushed through (Fig. 5).

When inserting the elements in the housing 10, the correct alignment is achieved by the ribs 13 on the inner wall of the housing 10 and the corresponding, laterally arranged on the elements 20 and 30 recesses 23.

The connecting element 30 is either a stamped sheet metal, preferably a copper sheet and is thus itself electrically conductive, or it is made of plastic and has an electrically conductive coating 32. The contact elements 50 fastened to the connecting element 30 or inserted into the bores 31 are thus connected to one another in an electrically conductive manner via the connection on the connecting element 30.

Figures 8 and 9 respectively show a front view and a side view of one embodiment of a contact element 50. The contact element 50 is fixed to one end of a cable 40 in an electrically conductive manner with the wire of the cable 40. For this purpose, the end of the cable 40 can be stripped or the insulation of the cable 40 is at least partially penetrated by the latter when attaching the contact element 50 so that an electrically conductive connection is made to the wire. For this purpose, the contact element 50 has a fastening region 51. The design of such

Range is well known, for example, the attachment and contacting with crimping. The contact element 50 passes from the attachment region 51 into a plug-in region 52. The plug-in area 52 is shaped and dimensioned such that the contact element 50 can be easily inserted into the bushing 24, but still experiences sufficient support and guidance through the wall of the bushing 24. The plug-in region 52 is divided into an upper fixing zone 53 and an adjoining contact zone 54. In the region of the fixing zone 53, a lock 55 in the form of arms or wings is formed which protrude beyond the corresponding plane of the outer contour surface of the fixing zone 53 and are elastically deformable. FIG. 10 shows the longitudinal section from FIG. 5, in which the cable 40 or the contact element 50 of FIG. 9 is inserted and connected to further cables (not shown).

For this purpose, the shaped body 20 and the connecting element 30 are aligned with each other such that passage 24 and bore 31 are in alignment.

Then, the contact element 50 is inserted into the bushing 24 first to the fixing zone 53. Upon further insertion, the over the outer contour of the

Contact element projecting latch 55 elastically deformed by the respective, arranged laterally in the implementation locking strip 26 and pushed back into the plane of the outer contour, so that the contact element 50 can also be inserted with above the contact zone 54 lying areas in the passage 24.

It is inserted so far, until it rests with an edge on the stop 25 and can not be pushed further. The fixing zone is dimensioned such that at this position, the latch 55 is guided past the lower edge of the locking strips 26 and the resilience of the elastically deformed latch 55 causes each of the upper edges 56 of the latch 55 is respectively positioned below a locking strip 26.

Thus, the contact element 50 is fixed positively via its fixing zone 53 in the bushing 24 in the molding 20 between the stop 25 and the locking strip 26. Thus, each connected to the contact element 50 cable 40 is mechanically attached to the molding 20.

The molded body 20 and the contact element 50 are coordinated and dimensioned so that the contact element 50 protrudes in its end position with the tip of its contact zone on the lower end face 21 u out so that the tip engages the bore 31 of the connecting element 30 and thereby electrically connected to the connecting element 30 and via the electrical conductivity of the connecting element 30 with other cables 40 (not shown) is connected. The molded body 20 and the cable 40 and the contact element 50 are also coordinated and dimensioned so that the contact element 50 is in its final position to the top of the contact zone 54 completely within the bushing 24 and the insulation of the cable 40 at least partially extends into the passage 24, so that the cable 40 is electrically insulated to the outside.

In addition, the material of the molded body 20 also insulates the cables 40 or the corresponding contact elements 50 inserted and held in the molded body 20 with one another. This allows only certain cables to be connected via the connecting element, e.g. can be connected to each other via interconnects.

FIG. 11 shows the shaped body 20, the connecting element 30 and the cable 40 from FIG. 10 inserted into the cavity 11 of the housing 10 in a longitudinal section.

The molded body 20 and the connecting element 30 are aligned with the laterally disposed recesses 23 and the corresponding ribs 13 on the housing 10 to each other. The ribs 13 each have a step 15 on their side remote from the opening 12 at the bottom of the housing 10. The inserted in the cavity 11 connecting element 30 rests on these steps 15 and is laterally supported by the ribs 13. In the illustrated embodiment, 3 ribs 13, each with a step 15 are used. Other, not shown embodiments with more than 3 ribs or even with a rib are also possible. It is also possible that not all ribs have a step (not shown).

The up or abutment of the connecting element 30 on the steps 15 of the ribs 13 causes a gap 16 between the transverse to the longitudinal axis of the housing 10 inserted connecting element 30 and the lower part of the housing wall remains, so that the tips of the contact zone 54 of the inserted contact elements 50 can also stand over the connecting element 30 addition. This ensures that contact elements 50 can be safely plugged in and also do not push out of the connecting element 30 again because the tips of the contact zone 54 come into contact with the housing wall.

In the illustrated embodiment, a locking lug 14 is formed on the rib 13, in the region of the opening 12 facing part. The locking lug 14 engages behind (FIG. 12) End face 21 o of introduced into the cavity 11 to its end position molding 20. Alternatively or in addition to the molding could also with an adhesive (not shown) are fixed in the cavity 11.

The outer contour of the shaped body 20 is slightly conical here in the embodiment, i. the diameter of the lower end face 21 u is smaller than the diameter of the upper end face 21 o, wherein the upper end face 21 o is the side which faces the opening 12 when the molded body 20 in the cavity 11 of the housing 10th

is introduced. In this way, the molded body can be easily inserted initially, while its outer surface 22 approaches more and more the inner wall of the housing 10 with increasing insertion depth and the surfaces in the end position abut each other (Fig. 11).

FIG. 13 shows an alternative contact element 50 in a further exemplary embodiment.

Compared to the one already shown here, the plug-in area 52 is designed such that a barb 58 is formed on each of the tips of the contact legs 57. The barbs 58 have a slope in the insertion direction. When inserting the contact legs 57 in a bore 31 of a connecting element 30, the slope comes into contact with the inner surface of the bore 31st Upon further insertion and insertion through the bore 31 causes the slope that the contact legs 57 are pressed toward each other and the mating portion 52 can be passed through the bore 31 therethrough. Once the barbs 58 are passed through the bore 31 and no longer abut laterally against the inner surface of the bore 31, spread the elastically compressed legs 57 on. As a result, the rear side of the barb 58 following the bevel bears against the rear side of the connecting element 30. Because the

Back of the barbs 58 each perpendicular or nearly at right angles to

Longitudinal axis of the contact element 50 extends, a withdrawal of the contact element 50 from the bore 31 is effectively prevented and the contact element 50 thus locked against unintentional release (Fig. 14). With suitable means, a plugged and thus locked contact element 50 would also solve again.

This embodiment can be combined with the described lock on the basis of the elements 55 and 26 or even be used without the elements 55 and 26 alone. Figure 15 shows a plan view of a connecting element 30. In a further developed embodiment, the connecting element 30 is formed as a printed circuit board, ie it is made of a conventional printed circuit board material, drilled and electrically conductive coated, the coating still to

Tracks 33 was structured. A conductor 33 connects at least two holes 31 in an electrically conductive manner with each other.

As a result, several cables can be plugged into a cable connector 1, which can be connected together in groups of at least two or more than one group. These arrangements can be in one

Cable connectors can also be combined, so that even more complex connections can be realized.

Of course, it is also possible to use contact elements 50 of different sized cross sections, e.g. a larger one for a ground terminal, smaller for power lines and very small for data lines (not shown) or cables with different potentials to each other.

For such more complex forms of cable connectors it is necessary to position at least the connecting element 30 in a defined manner, so that different cables can also be plugged precisely. In a further embodiment, this is achieved in that the ribs 13 and the recesses 23 located laterally on the peripheral surfaces of the elements 20 and 30 are nonuniform and with

different angles W1, W2, W3 are arranged to each other (Fig. 16).

In this way one obtains a coding, i. the following into the cavity

inserted elements can only be used properly or defined aligned in the housing. So it can be ensured that the each other too

connecting cables are inserted in the corresponding, correct feedthroughs and interconnected correctly. Of course, to the illustrated embodiment to

Coding other possibilities conceivable, e.g. different sized ribs, markings etc.

In a further embodiment (FIG. 17), further elements 60 are applied to the connecting element, in particular in the embodiment as a printed circuit board implemented in the material of the molding or in the wall of the housing. These other elements 60 may, for example, sensors, such as sensors for measuring the current or the voltage, for a temperature detection o.ä. be or components against electromagnetic interference. Possibly. Required Ankontaktierungen could also be realized with plugged into the molding contact elements and connected cables.

To complete a cable connector according to the invention with ready-inserted cables, it is useful to protect them against environmental influences, especially against moisture.

Figure 17 shows a cable connector with a housing 10, which over the in

Cavity 11 located elements 20 and 30 protrudes and forms a supernatant 17. This supernatant 17 is filled with a suitable material 71, in particular with a liquid resin poured out and then cured. As a result, the cable connector is sufficiently protected against moisture and connected to a structural unit.

Alternatively or in combination, a cable tie can be covered with a shrink tube 72 and shrunk. This can also be the outer contour of the

Housing 10 suitably shaped and with a flange for the

Be provided heat shrink tubing (Fig. 18).

In another embodiment, the shrink tube 72 is also with

Sealed sealant 73, especially when the input or. Exit the cables 40 (Figure 18) into the shrink tube 72 in or out. This again increases the mechanical strength and shielding against external influences. LIST OF REFERENCE NUMBERS
