Definitions

  • the invention relates to an electrical connector of the type specified in the preamble of claim 1.
  • the connector according to DE 24 32 122-C3 not only has handling disadvantages, since it is very small, it is in particular also not adequately secured against tension. There is a provision that such connectors must withstand a 30N pull. Also, such a connector cannot always be arranged in the necessary installation situations. He can, once with an egg provided with a cable, and cannot be adapted at any time with another system.
  • a common problem of all known solutions is that a large number of very fine cable cores are often present in different numbers on site, i.e. must be equipped at the construction site with an appropriate connector, which is sometimes very difficult with the known solutions, and in addition the connection must be such that it also meets the mechanical stresses that occur on site.
  • the object of the invention is therefore to provide a solution which, while maintaining sufficient train protection, enables simple installation, in particular cable core separation with simple means, while at the same time adapting to different installation situations.
  • this object is achieved according to the invention in that in the electrical connector of the type specified in the preamble of claim 1, this connector is equipped with a cable separating element.
  • a locking bracket on an additional housing part makes it possible to ensure optimum train protection, while at the same time creating an easily manageable plug, specifically by means of the further housing part, which at least partially encloses the known connector, so that different installation situations can be detected .
  • DE 89 06 957-U1 shows a connector for different internals, which, however, only serves to accommodate a generic plug contact in different inlet situations of the telephone cable, without additional train protection being provided.
  • the invention provides for this that the latching bracket is fixed via a clamp connection on the second housing part, the clamp connection being releasable via an insertion tool.
  • an appropriately equipped cable can be pre-assembled in the factory with a connector with the locking bracket according to the invention. If the locking bracket is not required on site, it can be unlocked, for example, by simply inserting a screwdriver and thus released.
  • the invention also provides that a receiving element for holding an anti-kink sleeve on the cable is arranged in the further housing part.
  • This receiving element in turn serves to relieve the strain or to initiate a pull exerted on the cable into the further housing part.
  • the receiving element has a cable core separating rail. This simplifies the assembly of the plug-in elements, in particular the cable cores.
  • the separating rail has a deflection contact surface for deflecting the cables is assigned to wires by 90 ° with a free space in the area of the deflection surface to form cable loops greater than 90 °.
  • This measure further takes into account the primary aim of the invention, to compensate for a train possibly being exerted on the connection.
  • a cable core lying against the deflection surface is braked there.
  • the free space for the formation of cable loops greater than 90 ° is particularly expedient in order to be able to take into account any tension that may be exerted by extending the cable cores within this stretch connection.
  • the invention also provides that a socket is provided in the further housing part of the cable input, in particular for receiving TAE plugs, that is to say plugs which are standardized as a telecommunications connection input.
  • the connector generally designated 1 according to Fig. 1 is used for coupling an electrical cable, e.g. a telephone cord 2 with a plurality of adjacent wires 3 (FIG. 2) which are electrically contacted in a first housing part designated by 4.
  • the electrical contacts are designated 5 in FIG. 3.
  • Fig. 1 the electrical connector 1 is shown in a 90 ° deflection, but the invention is not limited to this, in the same way a coaxial connector / cable routing could also be provided.
  • Essential for the invention is the further housing part 6 in which the first housing part 4 is integrated or fixed there, as can be seen from the sectional drawing (FIG. 3).
  • the further housing part 6 is equipped with a locking bracket 7 for locking in a socket 8 (FIG. 3) or a further coupling element 9 (FIG. 1).
  • the locking bracket 7 is, as shown in Fig. 3, locked via a clamping tab 10 in the housing part 6, this clamping tab 10 can be pressed upwards by inserting a tool laterally in order to be able to remove the locking bracket 7 from a mounting slot 11 in the housing part 6 .
  • the latching bracket 7 has a hook bar 12 which can be locked in the socket 8 with a correspondingly opposite bar 13 or with a cam element 13a on the coupling 9.
  • a receiving element 14 is provided in the housing part 6 for holding an elbow grommet 15 on the cable 2.
  • the receiving element 14 has a cable core separating rail 16, which is assigned a deflection surface 17 in order to enable the cable cores 3 to be deflected by 90 °.
  • the deflection surface 17 is assigned a free space 18 such that the cable wires 3 can be inserted here to form loops, designated 19, these loops being greater than 90 °.
  • FIG. 1a The invention is shown in a modified embodiment in FIG. 1a, here the connector 1a shows in its further housing part 6a a socket 20 for receiving so-called TAE plugs.
  • the plug-in connection 1 a is designed as a transition module, it should be noted that the coupling 9 in FIG. 1 also represents a transition module, since the coupling 9 is equipped with a TAE plug 21 on the end facing away from your connector 1.
  • the locking bracket 7 has a pressure cam 22 on its undersides, which cooperates with a locking tab 23 on the first housing part 4. If the locking bracket 7 is pressed downward in FIG. 3, the cam 22 drives the locking bracket 23 out of engagement, the plug connection can thus be released.
  • FIG. 4 shows an embodiment variant in which a kink grommet 15b is provided on a cable denoted by 2b and bears a housing part generally denoted by 24.
  • This housing part 24 is equipped with a cable separating element 25, which by a Plastic plate is formed with drawn and designated 26 grooves for the individual cable cores.
  • a separating comb 27 is provided at the free end via a predetermined breaking point 28.
  • the first housing part is designated 29 here, its essential structure corresponds to the design according to FIG. 3 and the housing part 4 there, it has an insertion opening 30, a latching bracket 31 and an inwardly projecting locking cam 32.
  • the housing part 24 carries a hinge lock and a locking and locking cover 34 which can engage in the small locking cams 33 shown there.
  • a locking groove 35 is embossed in the cover 34, which in the coupling position interacts with the locking cam 32 on the first housing part 29 and provides strain relief for the cable wires or the plug connections.
  • the mode of action is as follows:
  • the cable 2b is inserted, the cable cores separated over the comb 27 and shortened in front of the comb, which is not shown in detail.
  • the lid 34 is closed and locked and the comb element 27 is bent over the predetermined breaking point 28, so that the cable cores protrude forward over this corresponding area.
  • the further housing element 24 can with its front part in the Opening 30 of the housing part 29 are inserted so that the contacts can be made inside.
  • the inwardly projecting locking cam 32 snaps into the locking recess 35 and the connection is completed.
  • FIG. 5 shows a modified example.
  • the further housing part, here designated 24a has a slightly different type of receptacle for the kink grommet 15c, otherwise the elements are essentially the same, so they also have the same reference number added to in "a" the embodiment of FIG. 4th
  • the supervision of a socket or coupling socket 36 is also shown in a simplified manner, where it is indicated that the receiving outline contour 37 of the engagement opening 30a can be profiled in such a different way in order to accommodate only a specific plug size, which, depending on the number of individual cable wires, may occur for example four, six or eight cable cores.
  • engagement cams 38 can be provided on the outer region of the housing part 24a, which engage in corresponding, outwardly projecting recesses 39 on the engagement opening 30a, the width or thickness of which is predetermined and only allow the entry of a correspondingly identical element, ie, will be there four-wire cable is required, the corresponding assignment tion at the engagement opening 30a with the recesses 39a so that only the corresponding cams 38a can engage there.
  • the locking element 7b designed as a locking bracket according to the embodiments of FIGS. 6 and 6a can also be used.
  • the width of the front engagement area which is denoted here by 40, can be adapted to an additional engagement opening 41, again depending on the number of cable wires concerned.
  • the difference between the embodiments of FIGS. 6 and 6a consists in the feeding of the cable 2c with the respective kink grommet 15.
  • the first housing part is formed by two substantially identical housing halves. These housing halves are produced as a plastic profile using the extrusion process. Such a profile bar is shown in Fig. 7.
  • the individual halves are designated 42a there.
  • the separating grooves are designated 26b here, they essentially correspond to the type and arrangement tion of those separating grooves 26 and 26a according to the explanations according to FIGS. 4 and 5.
  • a mounting element is shown in simplified form in FIG. 8.
  • An element half 42a is inserted into a corresponding recess 44 in a lower tool support 43.
  • the tool part 43 carries a separating comb 45 on its front side.
  • the cable 15e is placed on the tool base plate 43 with the cable cores 3e being separated via the comb 45.
  • the upper element 42a is identical in construction to the lower element 42a, placed from above and a tool 47 designed as a heating jaw with a front cutting blade 46 is lowered from above.
  • the heating tool 47 has a receptacle 48 on the inside for the upper plastic element 42a, a projection 49 being additionally provided in the receptacle 48. If the heating jaw 47 with the cutting blade 46 is now lowered from above, the free ends of the cable wires 3e projecting forward are first cut off and then the two elements 42a are welded to one another with the cable wires 3e being interposed.
  • an stamping here designated 35a
  • This indentation 35a corresponds to the locking groove 35, for example in the exemplary embodiments according to FIGS. 4 and 5. That now more finished element 42 is then inserted into corresponding further housing parts, for example into a housing part 29 according to FIG. 4 or a housing part 4 according to FIG. 1.
  • spout 15 can be designed to be shrinkable, in particular for a construction site assembly, this is shown in dashed lines and designated 15a.
  • a gel seal 50 can be provided in the coupling area, for example, in order to provide a moisture seal.
  • identification cams can be embossed onto the last-described housing part 42 during the welding process; if necessary, an angled grommet (not shown there) can also be molded on.
