Connector for flat electrical cables

The invention relates to plug dor im Generic term of claim 1 mentioned type, which allow not stripped wires of an electrical To contact flat cable by means of a so-called penetration technique. All that is needed is the the common cable jacket surrounding the cores to be removed, while the insulation of the individual cores enclosing conductor no longer needs to be removed, as is otherwise the case in telecommunications technology with screwing, Soldering, welding or crimping of contacts is necessary, e.g. to connect a telephone plug to the To connect flat cable.

In the case of the plug to be connected in the known penetration technology, a one-piece housing is provided a channel for receiving the cable end is provided that at its end region opposite the channel opening has a family of outer grooves running parallel to the channel, in which there are platelet-shaped grooves Plug penetration contacts that are perpendicular to the course of the canal lying next to each other. In the area of these penetration contacts, the receiving channel for the cable end is on the

The cross-section of the cores that are free of the sheath but still carry the full insulation on their conductors are tapered, with longitudinal ribs in the channel, the individual wires in alignment with the penetration contact permanently assigned to them hold in the outer housing groove. In the bottom of the groove there are openings through which the platelet-shaped Penetration contacts od by the blow of a hammer. The like. With their inner cutting ends in the tapered end of the channel are driven, there penetrate the insulation of the associated wires and hit the conductor in the insulation. This establishes contact, with the The other end of the platelet-shaped penetration contact remaining outside the housing is for the electrical contact of the plug to associated sockets od. The like. Determining contact end forms. at this known connector are created side by side. other contact points that are fixed to the corresponding Adjacent conductors are assigned in the wires of the cable end.

Such plugs are characterized by simple assembly because the stripped cable end is only pushed into the receiving channel of the housing and to be exerted on the piercing contacts pressure

needs, but there is the disadvantage that it is not adapted to other types of application Contacting the conductors in the individual cores are possible. The conductors in the veins can neither be connected in a different order to the known platelet-shaped piercing contacts, than is possible due to the position of the adjacent cores in the cable end, the conductor can still one single wire can be connected to several different piercing contacts.

In the known connector, the cable end is fixed by hammering in a resilient tongue.

The invention is based on the object of developing a connector of the type mentioned in the generic term, the easy-to-use penetration contacting of the Cable an optional assignment of the connection of the wire-conductor to the in a fixed arrangement to each other piercing contacts seated in the housing. This is achieved according to the invention by the features listed in the characterizing part of claim 1.

By dividing the housing into two parts, the cap and the insert that can be inserted into it, everyone can do this both components optimally fulfill their intended tasks. The cap is used to fix the end of the cable and for proper positioning-the unstripped Cores in separate holes. The use made possible by suitable selection of the Z-shaped knife from a group of differently strong Z-cranked knives to create a contact set there, whose protruding Z-legs, which serve as cutting edges, are in a certain arrangement pattern, which uses certain of the available piercing positions for the holes in the cap when the insert is mounted in the cap. The use is first of all,

/ ο-

when equipped with the selected Z-shaped knife, a knife holder. Then, during assembly In the cap, the insert equipped with the knives is a cutting tool that is used as a structural unit Whole contact set drives through at the desired piercing positions of the cap up to the wire conductors. Finally, after assembly, the insert takes on the function of forming a connector.

Reliably around the optional piercing points from the cutting ends of the Z-shaped knives during the assembly process To meet the insert in the cap, it is advisable to pass each puncture site through a guide chamber to form, which runs in the direction of insertion of the insert and therefore the cutting ends during the assembly process leads exactly to the place intended for them. The contact points of the exposed to the outside for connection purposes Z-legs in the connector always adopt the same uniform arrangement, regardless of which knife has been selected from the group of Z-shaped cranked knives to different degrees. The contact points will be expediently arranged in one or more rows in use that are parallel to the bores lying in the cap. Usually two rows are used and the insert is formed from one by means of locking positions od. The like. In the cap connectable mounting part and a remaining outside of the cap Core part from where the Z-legs exposed for contact purposes on opposite side surfaces of the core part and are expediently inserted into C-shaped profiled rails there. Outgoing from a Z-shaped knife inserted into one leg at a certain contact point

for the other leg serving as the cutting end, those piercing places in the Kajijjpe for Available, which are arranged in a plane lying perpendicular to the direction of the bore. Depending on, the extent to which the desired penetration point is removed from the specified contact point in the assembly state, the Z-shaped cranking of the knives is selected.

To accommodate the various Z-shaped crankings of the selected knives, the uniform insert expediently a sufficiently large recess on the side facing the cap, in which contact points, in the form of abutment surfaces or lateral shoulders are provided, which the support individually selected and inserted knife. This creates a reliable position for the Knife guaranteed during the piercing work when assembling the insert in the cap. Appropriately the direction of insertion of the knives in the cap is carried out in the same direction as the Insert is later inserted into the cap for assembly purposes.

It is of particular importance that the non-stripped wires in the cap are also in the intermediate piece mechanically to intercept, which between the selected piercing places for the cutting ends of the knife and the fixing point of the cable is in the cap. This allows for pulling, pushing and turning movements on the cable, as it occurs when the plug is used cannot continue into the contacting area of the cutting end on the wire conductor and there affect the electrical connection. Such

_{/ | s}

Interception points for the veins can be created by deforming the wall of the bore, for which purpose it is
It is advantageous to cut out a plug from the wall of the borehole and to press it into the borehole in some areas so that it is clamped there. This can be done in a blind hole within the cap. These measures are of general importance regardless of the mentioned task and solution of the Z-shaped cranked knife, which is why these measures can also be used in other cases.

In the drawings, the invention is shown in an embodiment, for example. Show it:

9 shows, in a larger enlargement, a cross-sectional view through the assembled plug along the Section line IX-IX of FIG. 8.

In terms of its housing, the connector consists of a cap Io and an insert 2o which can be inserted therein, the structure of which can best be seen from FIGS.

The cap.Io includes a channel 11 for receiving the am Best of Fig. 8 visible end 3o of a flat cable, which in a common cable sheath 31 several in one Level adjacent veins 32 carries. The cores in turn each consist of an insulation 33, in which the actual conductor 34, in the case of a telephone

cable a stranded wire consisting of several wires, is arranged. The cable end 3o is stripped so that, as 8 shows that the wires 32 are exposed, but have not yet been detached from their insulation 33. On the cable end 3o a kink protection sleeve 35 is firmly attached, which has a radial projection 36 for the purpose Fixing the cable end in the cap Io possesses.

For receiving the projection 36 of the anti-kink sleeve has, as best shown in Fig. 2, the channel has a recess 12, from which it extends over a funnel-shaped Transition piece 13 tapers in longitudinal bores, the number and width of the profile of the Corresponding to non-stripped individual cores 32. The definition of the cable end 3o in the cap Io takes place in the following way:

After, as already described, the cable end is provided with the anti-kink sleeve 35 and chipped has been, the cable end 3o is pushed into the channel 11 of the cap Io. The cores 32 are through the funnel-shaped transition piece 13 automatically in the bores 14 assigned to them, which, as can best be seen from FIG. 9, through a cap material.15 are separated. Ribs 16 provided in the funnel-shaped transition piece 13 form guide surfaces on this tour. The bores 14 are provided with closed walls all around, which is also opposite the guide chambers 17 pointing towards the underside of the cap, which are covered by a closure skin 18, apply. This allows the veins to run smoothly without being in alignment with the individual in multiple times Bores 14 arranged guide chambers 17 to remain hanging.

« / IS *

The wire ends 37 enter, as FIG. 8 shows, for control purposes in an end recess 19 of the cap, the end face of which can also serve as a stop for the wire ends 37. From the bottom of the cap Accessible from there is a blind hole 38 which is arranged in alignment with each bore 14 and by deformations 39> according to FIG. 8, of the original wall 4o lying between them, 2, an interception of the individual cores beyond that seated in the recess 12 mentioned Projection 36 of the anti-kink sleeve 35 creates in the channel. From this deformation point 39 is the Core 32 stopped in bore 14; Rotations, tensile loads and compressive loads act no longer results in a disruptive movement of the vein in the borehole 14.

These deformations 39 could also be generated in a way other than that shown, e.g. the wall 4o cuts out a profiled plug which is pressed in and thereby the core 32 in the Hole 14 intercepts. The plug jams itself and the core 32 it grips.

As evidenced by FIGS. 3, 5 and 9, the one-piece insert 2o consists of a widened assembly part 21, which ensures the connection with the cap Io, and a separate core part 22, which the electrical Contact points determined. On its side facing the cap Io, the insert 2o has a recess 23, from which piercing contacts in the form of Z-shaped knives 41 with one leg are vertically insertable. These Z-legs are passed through openings 24 in the bottom of the recess 23 and arrive in the adjoining core part 22 in C-profiled,

undercut longitudinal grooves 25. When the knives 41 are fully inserted, they lie through the cranked portion certain Z-webs of the individual knives at contact points in the recess 23, namely on abutment surfaces 25, which catch the Z-bar behind. There are also lateral shoulder surfaces as additional contact points provided in the recess 23, which, at least in some cases, adjoins the Z-web 43 Accompany the beginning areas of the other Z-leg 44 '.

The knives have the basic structure shown in FIGS. 6 and 7. The knife 41 consists of one Z-shaped sheet metal strip with a special outline. The end of the Z-leg 42 to be inserted into the insert 2o is sharpened with regard to the sheet thickness, as FIG. 6 shows, and the sheet outline is rounded, as can be seen from FIG. This makes threading the Z-knife easier.

in the inserted state when the Z-legs are in the grooves 27 of the core part 22 are positioned, the legs form fixed contact locations for the plug when the plug is connected to a corresponding one complementary socket cooperates. These Z-legs 42 can therefore be used as the "contact ends" of this knife-like penetration contacts 41 are perceived. These Kpntaktenden 42 are uniform in all knives 41 educated. ■.

All knives 41 also have a corresponding uniform design with regard to the other Z-leg 44. There are initially laterally projecting shoulders 45 provided, which are designed accordingly, not closer The contact points shown in the interior of the recess 23 lie down and pressure loads in the case of the still more detailed

Insert writing plug-in assembly of the insert 2o into the cap Io. The Z-legs 44 finally end in double points 46, which serve as cutting edges, on which there are sawtooth profiles on both longitudinal sides of the leg 47 connect. Which are used for anchoring to be described in more detail. Those applicable to the invention Knives 41 differ from one another with regard to the strength of the Z-shaped offset, that is to say the offset of the two legs 42, 44 to each other, which can be read from the length of the Z-web 43 lying in between. This results from the objective according to the invention when assembling the connector, for which the following applies:

To assemble the plug, the insert 2o equipped with the knives 41 is inserted as a structural unit into the cap Io introduced. The Z-legs protruding from the insert 2o form an arrangement pattern with one another, which is different from the Selection of the knife 41 used in each case with regard to the extent of their cranking 43 depends. Dio Cutting edges 46 of these Z-legs 44 initially pass into a guide chamber 17 assigned to it, When the insert according to FIG. 3 is moved into the cap Io in the sense of the arrow 5o shown there. The guide chambers 17 cause precise centering

• 25 and direct the cutting edges 46 to the closure skin 18 • in the bottom of the. Chamber 17, which is pierced. With the further insertion movement 50, the cutting edges penetrate into the bore 14 assigned to them and penetrate the insulation of the previous there in the cap Io positioned core 32, where they contact with the conductor 34 in perfect electrical connection. Which guide chamber 17 of the various bores 14 is effective here depends on the extent of the. Warping 4 3 of the knife used here 41. This

• β

is based on the following aspects:

As already mentioned above, the Z-legs 42, which act as contact ends, occupy fixed contact locations 48 on the core part 22 of the plug. Accompanying longitudinal ribs 51 between the contact sites 48 of the plug-in core member 22 is a defined contour profile, the connection makes it capable for specific sockets, which have a corresponding complementary profile opening. As can best be seen in FIG. 5, these contact locations 48 lie next to one another in two rows 6o, namely on the two longitudinal sides of the aforementioned core part 22 in the insert 2o. These two planes of arrangement of the contact locations 48 are parallel to the direction of the boreholes 14 if the assembly state of the plug according to FIG. 8 is considered. By selecting a knife with a suitable offset 43, the invention now enables the cutting edges of the other associated Z-leg 44 to make contact with the conductor of a certain desired core 32 of the cable. It is only necessary to ensure that, starting from the contact point 48 in the insert 2o, this 'Z-leg 4', which acts as a cutting end, is offset to such an extent that it can be inserted in the aforementioned insertion movement 5o of FIG.

the corresponding laterally offset guide chamber 17 meets, which directs him to the associated core 32 in the hole. Seen in the assembled state of the connector thus a given contact location 48 in the core part 22 has a set of corresponding to the number of bores 14 Guide chambers for the Z-leg 4 4, which acts as the cutting end, are available. The ones in the plane of this Considered contact place 48 arranged guide chambers 17 thus offer selectable penetration points for the knife 41. These guide chambers 17 are located

* / Ϊ3 *

61
that is, in a plane which is oriented perpendicular to the direction in which the bores 14 extend. The openings of the guide chambers 17 are therefore to be regarded as optional piercing locations 49 for the cutting Z-leg 42.

Thus, the invention makes it possible, starting from a uniform cap lo, to develop a plug, the contacts of which can be electrically connected to the conductors of the individual wires 32 in various ways.

The invention is a group of different knives 41 available, which are due to their cranking differ, that is, have Z-webs 43 of different lengths from one another. Depending on which one If a predetermined contact point 48 is to be connected to the wires, the corresponding knife 41 is selected and at this point 23, 24, 27 inserted into the insert 2o, where it is fixed for the plug assembly anchored, but can be exchanged for another knife when the plug is dismantled. As can be seen the desired contacting of the various wires 32 in the cap Io is achieved through the selection of the knife; the cutting-effective Z-legs 4 4 take a certain one. Arrangement pattern to each other, whereby certain piercing places 49 in the cap Io are used will. As can be seen from a comparison in FIG. 9, the height of the Z-web 43 can depend on the extent the offset vary.

When inserting 5o of the insert 2o into the cap reaches its mounting part 21 between deeply drawn side surfaces 52 of the cap lo, where a connection between these two components takes place. For this purpose, locking postures are used in the present case, which from Latching projections 53, 54 on the mounting part 21 of the insert

and consist of corresponding locking openings 55, 56 in the side walls 52, which in the vertical Insertion movement come into engagement with each other by themselves and secure the end position. As can be seen from Fig. 9, get the upper edges of the shoulders 45 in front of the bottom surface of the cap. The Mounting part 21 of the insert 2o, according to FIGS. 3 and 8 with a projection 28 in the area behind the recess 1.2 of the introduced anti-kink sleeve 35, whereby the use contributes to the definition of the cable end.

The cap Io has a recessed field 57, in which a label indicating the manufacturer and type of connector can be stored in a protected manner.

In order to achieve a resilient securing of the plug when in use, a 2o is on the insert in the invention integrally molded latching hook 29, the free end of which is covered by an end wall 58 of the cap. in the In the assembled state of the plug, as best seen in FIG. 8, the sawtooth profiles 47 at the cutting edge Z-leg 44 of the knife into the wall areas of the cap in the vicinity of the / selected bore 14.

As has already been mentioned, it is easily possible in the connector by appropriate selection, different cranked knives -41 a different contacting of the Bring out wires 32 of the cable. When it comes to being able to recognize this externally, so you can leave the cap Io, but then choose an insert whose core part 22 differs from this is profiled, e.g. has a different positioning or dimensioning of the ribs 51. So can a unwanted interchanging of the plugs with different 'contacts can be prevented and yet a uniform

Licher construction of the connector from a few components guaranteed.

In FIG. 5, the dash-dotted lines 60 indicate the parallel plane of arrangement of the contact locations 48 in Insert shown, which is aligned with the longitudinal course of the bores 14 in the cap Io is what has already been discussed. The dot-dash line in FIG. 8 continues to be the one perpendicular to the bores running arrangement plane 61 indicated, in which the optional penetration points 49 or guide chambers 17 for the optional entry of one to one Specific contact point 48 inserted knife 41 for its cutting Z-leg 44 result.

It should also be mentioned that, according to FIG. 3, the insertion direction 53 of the knife 41 in the insert 2o takes place in the same direction as the aforementioned insertion movement 5o of the insert 2o in the cap lo. As a result, the knife 41 used is loosened during the assembly process of the plug excluded. In Fig. 9, the offset of the contact location 48 in use is 20 from the selected one Penetration point 49 in the cap Io is designated by 59 and corresponds to the length of the Z-web 43 in the associated Knife 41.
