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 wiring harness with at least two interconnected via such a cable connector cables 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 or welded together, so that a Aufdrillen and peeling 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, i. squeezed with a device or a pliers transversely to the longitudinal axis and permanently deformed so that it clamps the inserted cable and fixed together, wherein the electrical connection is made via the contacting wires. Instead of being made of a soft metal, the tube can also be made of a plastic material which contracts under the influence of heat and likewise permanently contracts the cables fixed to one another, a so-called heat-shrinkable tube.

1 shows an example of a simple cable connection from 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 wires are usually additionally soldered or welded together to improve the connection.

Another improvement is the 2 In this case, the twisted together cables are aligned parallel to the actual cable run and the interconnected cables are so embedded in a sheath, so that the connection point lies 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 3 a sheath made of a shrink tube is used, wherein the interconnected cables are only passed through one side of the tube. 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.

4 shows an exploded perspective view of a cable connector according to the invention 1 , This includes a housing 10 , one from the housing 10 enclosed cavity 11 as well as an opening 12 in the case 10 to access the cavity 11 , In the illustrated embodiment, the housing 10 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 with ribs 13 Mistake. These stiffen the wall and the housing 10 becomes more dimensionally stable. It is at least a rib 13 intended. In the embodiment, the housing 10 with 3 ribs 13 shown. These are arranged in the same angular pitch W to each other.

In the cavity 11 introduced are a connecting element 30 and a shaped body 20 , The connecting element 30 gets into the cavity first 11 introduced and then the molding 20 so the front side 21o of the molding 20 the opening 12 is facing.

The molded body 20 points from a front side 21o to the other end face 21u bushings 24 for the cables 40 on. For stiffening and subsequent mechanical fixation are provided for each connection ends of the cable 40 each with a contact element 50 fitted.

These contact elements 50 be on the front page 21o in the bushings 24 of the molding 20 inserted and through the molding 20 to the other end face 21u passed. In this case, the contact elements occur 50 on the other side of the molding 20 far enough that these with the tips in corresponding holes 31 of the connecting element 30 intervention.

As the connecting element 30 itself electrically conductive or at least electrically conductive coated, which are on the connecting element 30 connected cables 40 electrically connected to each other. 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 can also 20 and the connecting element 30 integrally formed, for example, be glued together (not shown).

5 shows the shaped body 20 and the connecting element in a longitudinal section. The implementation 24 is for receiving the cable or the contact element 50 intended. The implementation has a stop 25 on, the insertion movement of the cable 40 or of the contact element 50 limited and thus defined a certain end position. It is envisaged that the cables 40 with the contact elements 50 can be plugged by hand instead of being pressed in mechanically or with mounting devices. Since there are then no sufficient holding forces by a pressure, a separate lock is necessary. These are in the implementation of each side locking strips 26 arranged for fixing or locking one in its end position, ie until it stops 25 inserted contact element 50 ( 10 ). The locking strips 26 Do not run over the entire length of the implementation, but end within this and each form a stop 25 spaced edge 27 out.

The 6 and 7 each show plan views of the molding 20 ( 6 ) or the connecting element 30 ( 7 ). moldings 20 and connecting element 30 are aligned with each other so that the bushings 24 and the corresponding associated holes 31 each in an escape, so that one through an implementation 24 inserted contact element 50 with its tip in a corresponding hole 31 of the connecting element 30 can be intervened or pushed through ( 5 ).

When inserting the elements into the housing 10 gets the right alignment to each other through the ribs 13 on the inner wall of the housing 10 and the corresponding, side to the elements 20 and 30 arranged recesses 23 reached.

The connecting element 30 is either a stamped sheet metal, preferably a copper sheet and thus is itself electrically conductive, or it is made of plastic and has an electrically conductive coating 32 on. The on the connecting element 30 fastened or in the holes 31 used contact elements 50 are thus on the connection on the connecting element 30 electrically connected to each other.

The 8th and 9 each show a front view and a side view of an embodiment of a contact element 50 , The contact element 50 is at one end of a cable 40 electrically conductive with the wire of the cable 40 attached. This can be the end of the cable 40 be stripped or the insulation of the cable 40 is when attaching the contact element 50 at least partially so penetrated by this, that an electrically conductive connection is made to the wire. The contact element 50 has a mounting area for this purpose 51 on. The design of such a range is well known, for example, the attachment and Ankontaktierung with crimping. The contact element 50 goes from the attachment area 51 in a plug-in area 52 above. The plug-in area 52 is shaped and dimensioned so that the contact element 50 easy to carry 24 can be plugged, but still sufficient support and guidance through the wall of the implementation 24 experiences. The plug-in area 52 splits into an upper fixation zone 53 and an adjoining contact zone 54 on. In the area of the fixing zone 53 is a lock 55 formed in the form of arms or wings, each over the corresponding plane of the outer contour surface of the fixing zone 53 stand out and are elastically deformable.

10 shows the longitudinal section of the 5 in which the cable 40 or the contact element 50 of the 9 plugged in and connected to other cables (not shown).

This is the molding 20 and the connecting element 30 aligned with each other so that implementation 24 and bore 31 to be in flight.

Then the contact element 50 in the implementation 24 first to the fixation zone 53 plugged in. Upon further insertion, the protruding over the outer contour of the contact element locking 55 through the respective locking strips arranged laterally in the passage 26 elastically deformed and pushed back into the plane of the outer contour, so that the contact element 50 also with above the contact zone 54 lying areas in the implementation 24 can be inserted.

It is pushed in until it hits the edge with one edge 25 seated and can not be pushed further. The fixing zone is dimensioned so that at this position the lock 55 at the lower edge of the locking strips 26 has passed and the springback of the elastically deformed latch 55 causes each of the top edges 56 the lock 55 each below a locking strip 26 is positioned.

This is the contact element 50 about his fixation zone 53 in the implementation 24 in the molding 20 between the stop 25 and the locking strip 26 fixed in a form-fitting manner. Thus, this is also the case with the contact element 50 connected cables 40 mechanically on the molding 20 attached.

The molded body 20 and the contact element 50 are coordinated and dimensioned so that the contact element 50 in its final position with the tip of its contact zone over the lower end face 21u so protrudes so that the tip into the hole 31 of the connecting element 30 engages and thereby electrically conductive with the connecting element 30 and on the electrical conductivity of the connecting element 30 with other cables 40 (not shown) is connected.

The molded body 20 and the cable 40 or the contact element 50 are also coordinated and dimensioned so that the contact element 50 in its final position to the top of the contact zone 54 completely within the implementation 24 lies and the insulation of the cable 40 at least partially in the implementation 24 extends into it, leaving the cable 40 is electrically insulated to the outside.

The material of the molding 20 also isolates the cables 40 or the corresponding in the molding 20 inserted and held contact elements 50 among themselves. This makes it possible that in each case only certain cables can be connected to one another via the connecting element, for example via conductor tracks.

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

The molded body 20 and the connecting element 30 are with the laterally arranged recesses 23 and the corresponding ribs 13 on the housing 10 aligned with each other. Ribs 13 each at their from the opening 12 facing away from the bottom of the housing 10 a step 15 on. That in the cavity 11 inserted connection element 30 lies on these steps 15 on and gets to the side of the ribs 13 supported. In the illustrated embodiment, 3 ribs 13 with one level each 15 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 concern of the connecting element 30 on the steps 15 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 so that the tips of the contact zone 54 the inserted contact elements 50 also via the connecting element 30 can stand out. This ensures that contact elements 50 be sure to get stuck and not back out of the connector 30 squeeze out because the tips of the contact zone 54 come into contact with the housing wall.

In the embodiment shown is on the rib 13 , in the area of the opening 12 facing part, a catch 14 educated. The catch 14 engages behind 12 ) the front side 21o in the cavity 11 introduced to its end position molding 20 , Alternatively or in addition thereto, the shaped body could also be provided with an adhesive (not shown) in the cavity 11 be fixed.

The outer contour of the molding 20 is here in the embodiment slightly conical, ie the diameter of the lower end face 21u is less than the diameter of the upper end face 21o , where the upper end face 21o the side is that of the opening 12 is facing, when the molding 20 in the cavity 11 of the housing 10 is introduced. In this way, the molded body can be easily inserted initially, while with increasing insertion depth its outer surface 22 more and more of the inner wall of the housing 10 approaches and the surfaces in the end position abut each other ( 11 ).

13 shows in a further embodiment, an alternative contact element 50 ,

Compared to the already shown here is the plug-in area 52 designed so that at the tips of the contact legs 57 one barb each 58 is formed. The barbs 58 have a slope in the insertion direction. When inserting the contact legs 57 into a hole 31 a connecting element 30 the slope comes into contact with the inner surface of the bore 31 , Upon further insertion and insertion through the hole 31 conditionally the slope that the contact legs 57 pressed against each other and the plug-in area 52 through the hole 31 can be passed through. Once the barbs 58 through the hole 31 have passed through and no longer on the side of the inner surface of the bore 31 abut, spread the elastically compressed legs 57 on. As a result, the back of the barb following the slope lies 58 at the back of the connecting element 30 at. Because the back of the barbs 58 each at right angles or nearly at right angles to the longitudinal axis of the contact element 50 runs, is a pulling out of the contact element 50 out of the hole 31 effectively prevented and the contact element 50 thus locked against unintentional release ( 14 ). With suitable means would be a plugged and thus locked contact element 50 but also let solve again.

This embodiment can with the lock described by means of the elements 55 and 26 combined or without the elements 55 and 26 used alone.

15 shows a plan view of a connecting element 30 , In a further developed embodiment, the connecting element 30 designed as a printed circuit board, ie it is made of a conventional printed circuit board material, drilled and coated electrically conductive, wherein the coating is still to traces 33 was structured. A trace 33 connects at least two holes each 31 electrically conductive with each other.

This can be done in a cable connector 1 several cables are plugged, which can be connected to each other at least in pairs or even in groups. These arrangements can also be combined in a cable connector so that even more complex connections can be realized.

Of course it is also possible to contact elements 50 To use different sized cross-sections, for example, a larger for a ground terminal, smaller for power currents and very small for data lines (not shown) or cables with different potentials to interconnect.

For such more complex forms of cable connectors, it is necessary at least the connecting element 30 defined position, so that different cables can also be plugged exactly. In a further embodiment, this is achieved in that the ribs 13 as well as each laterally on the peripheral surfaces of the elements 20 and 30 located recesses 23 unevenly and at different angles W1, W2, W3 are arranged to each other ( 16 ).

In this way one obtains a coding, i. the following elements inserted into the cavity can only be properly aligned or defined aligned in the housing. This ensures that the cables to be connected together are inserted into the corresponding, correct feedthroughs and correctly interconnected. Of course, other possibilities are conceivable for the illustrated embodiment for coding, e.g. different sized ribs, markings etc.

In a further embodiment ( 17 ) are on the connecting element, in particular in the embodiment as a printed circuit board further elements 60 applied or implemented in the material of the molding or in the wall of the housing. These other elements 60 For example, sensors, such as sensors for measuring the current or the voltage, for a temperature detection or similar. 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.

17 shows a cable connector with a housing 10 which over the in the cavity 11 located elements 20 and 30 survives and a supernatant 17 forms. This supernatant 17 comes with a suitable material 71 filled, poured in particular with a liquid resin 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 with a shrink tube 72 be covered and shrunk. This can also be the outer contour of the housing 10 suitably shaped and provided with a flange for the shrink tube ( 18 ).

In another embodiment, the shrink tube 72 also with sealants 73 filled, in particular when entering or leaving the cable 40 ( 18 ) in the shrink tubing 72 in or out. This again increases the mechanical strength and shielding against external influences.
