Definitions

  • the invention relates to an electrical socket with a housing that has a plug receptacle for inserting a plug connector and a cable receptacle for inserting a data transmission cable, with several contact springs being arranged in the plug receptacle, which can be contacted by assigned plug contacts of the plug connector and can each be electrically connected to a wire connection element , and with a wire receiving part that can be inserted into the cable receptacle together with the data transmission cable and positioned on the wire connection elements for receiving the wires of the data transmission cable, and with at least one strain relief part that can be moved back and forth between a release position spaced apart from the data transmission cable and a strain relief position that rests on the data transmission cable.
  • Such an electrical socket is used in particular in communications and data transmission technology.
  • the socket interacts with a corresponding plug connector. Through the interaction, a detachable electrical connection can be established, for example, between two data transmission cables.
  • the electrical socket has a plug receptacle in which several contact springs are arranged.
  • a corresponding connector can be inserted into the connector receptacle, with the contact springs arranged in the connector receptacle being able to be contacted by associated plug contacts of the connector.
  • the contact springs are each electrically connected to a wire connection element.
  • the wires of a data transmission cable can be connected to the wire connection elements.
  • the electrical socket on a wire receiving part that receives the wires of the data transmission cable and together with the data transmission cable in a Cable receptacle of the electrical socket can be inserted and positioned on the wire connection elements, so that an electrical connection can be made between the wire connection elements and the wires of the data transmission cable.
  • the data transmission cable can have 2, 4, 6 or 8 wires, for example.
  • the electrical socket usually has at least one strain relief part that can be moved back and forth between a release position in which the strain relief part is at a distance from the data transmission cable and a strain relief position in which the strain relief part rests on the data transmission cable.
  • the at least one strain relief part With the aid of the at least one strain relief part, external forces and moments acting on the data transmission cable can be intercepted in order to avoid undesired mechanical loading of the connection between the wires of the data transmission cable and the wire connection elements of the socket.
  • Snap-in connections between the wire receiving part and the housing are often used to secure the position of the wire receiving part in the housing.
  • Such snap-in connections are, for example, from DE 100 51 097 C2 known.
  • This publication proposes a U-shaped additional part for fixing the wire receiving part in the housing, which has two side walls aligned parallel to one another and which are connected to one another via a rear wall. On their upper side, the side walls carry an inwardly directed guide edge and on their lower side, the side walls carry inwardly directed guide rails.
  • the additional part can be pushed laterally onto the housing of the plug connector, with the inwardly directed guiding edges contacting a bevel of the wire receiving part that is complementary to the guiding edges, so that the wire receiving part is displaced in the direction of the wire connection elements when the additional part is pushed onto the housing and is in a final assembly position is specified on the wire connection elements.
  • the attachment has two flexible jaw parts. After sliding the additional part on the housing, the jaw parts form a cable support behind the housing.
  • the jaw parts can be locked with a strain relief part, which is designed like a clamp.
  • the strain relief part surrounds the rear of the data cable protruding from the cable holder and makes it possible to absorb external forces and moments acting on the data transmission cable.
  • an electrical socket in which a cover is pivotably mounted on the housing. A pivoting movement of the cover slides the wire receiving part in the direction of the wire connection elements. The cover can be snapped onto the housing to secure the position of the wire receiving part.
  • a cable support is arranged on the back of the cover facing away from the housing, on which the data cable protruding from the cable holder can be fixed by means of a clamp-like strain relief part surrounding the data transmission cable in order to absorb external forces and moments acting on the data transmission cable.
  • a similarly designed electrical socket is from DE 10 2015 008 632 A1 known.
  • a pivotable cover is articulated on the housing, which forms a position lock for the wire receiving part.
  • a cable support protruding from the rear of the cover interacts with a strain relief part which can be moved from a release position spaced apart from the data transmission cable into a strain relief position adjacent to the data transmission cable in order to absorb external forces and moments acting on the data transmission cable.
  • an electrical socket is known in which a core receiving part can be inserted into a cable receptacle together with a data transmission cable fixed thereto in order to initially assume a pre-assembly position.
  • An insertion wedge can then be inserted perpendicularly to the direction of insertion of the wire receiving part into the cable holder, the wire receiving part being pushed by the insertion wedge into a final assembly position in which the wires of the data transmission cable fixed to the wire receiving part each contact a wire connection element.
  • the slide-in part In order to be able to insert the core receiving part into the cable receptacle, it is necessary for the slide-in part to assume a position separate from the housing of the socket, since otherwise the wire receiving part would be impeded by the slide-in part. After inserting the core receiving part, the slide-in wedge must be pushed completely into the cable receptacle so that the core receiving part reaches its end position.
  • the object of the present invention is to further develop an electrical socket of the type mentioned at the outset in such a way that it is easier to handle when connecting a data transmission cable and, on the one hand, the number of individual parts required for this is reduced in order to enable the socket to be produced inexpensively with a small size allow, and on the other hand a strain relief function for different diameters of the data transmission cable is realized.
  • the at least one strain relief part not only has the function of absorbing external forces and moments acting on the data transmission cable in order to avoid undesired mechanical stress on the connection of the individual wires of the data transmission cable to the wire connection elements of the socket, but also the at least one Strain relief part also has the function of moving the wire receiving part inserted into the cable holder together with the data transmission cable from a pre-assembly position into a final assembly position and fixing it in the final assembly position, in which the wires of the data transmission cable contact the wire connection elements of the socket.
  • the at least one strain relief part can be inserted into the cable holder, releasing the cable holder in the release position, so that in a first step the wire receiving part can be inserted into the cable holder together with the data transmission cable without being impeded by the strain relief part.
  • the core receiving part can assume a pre-assembly position in the cable receptacle, in which it is at a rather small distance from the core connection elements.
  • the at least one strain relief part can then be moved from its release position into its strain relief position, in which it dips into the cable receptacle.
  • the wire receiving part is pushed by the at least one strain relief part into its final assembly position, in which the wires of the data transmission cable make contact with the wire connection elements. If the at least one strain relief part assumes its strain relief position, it secures the core receiving part in the final assembly position and at the same time absorbs external forces and moments acting on the data transmission cable.
  • the handling of the electrical socket according to the invention when connecting a data transmission cable is therefore very simple.
  • the production of a strain relief and the positioning of the wire receiving part in its final assembly position takes place simultaneously during the same work step, namely during the movement of the strain relief part from the release position into the strain relief position. Only a few individual parts are therefore required to secure the wire receiving part and to produce a strain relief. This permits cost-effective production and enables the electrical socket to be small in size.
  • the at least one strain relief part can be fixed in the release position and in the strain relief position on the housing. This further simplifies handling of the electrical socket when connecting a data transmission cable, since the at least one strain relief part can be fixed in the release position on the housing together with the data transmission cable in the cable receptacle before the wire receiving part is inserted. As a result, the at least one strain relief part can assume a predefined position when the wire receiving part is inserted together with the data transmission cable into the cable seat. After inserting the wire receiving part together with the data transmission cable into the cable receiving area, the at least one strain relief part can be moved into its strain relief position and fixed again on the housing in this position.
  • the at least one strain relief part can be detachably latched to the housing in the release position and in the strain relief position.
  • the at least one strain relief part is thus fixed to the housing via a releasable latching connection, the latching connection having a plurality of latching steps for the at least one strain relief part in the strain relief position of the at least one strain relief part.
  • the at least one strain relief part has a thrust surface which, during the transition of the at least one strain relief part from the release position to the strain relief position, contacts a contact surface of the core receiving part assigned to the thrust surface in order to apply a shearing force to the core receiving part. If the at least one strain relief part is moved from the release position into the strain relief position, it exerts a shearing force on the core receiving part in that the shearing surface of the strain relief part contacts a contact surface of the core receiving part assigned to the shearing surface.
  • the core receiving part is moved from its pre-assembly position to its final assembly position, in which the cores of the data transmission cable each contact a core connection element, so that an electrical connection is established between the cores of the data transmission cable and the core connection elements of the electrical socket.
  • the thrust surface can have a curved geometry, for example.
  • the force-displacement diagram can be optimized, ie the at least one strain relief part can exert different shear forces on the contact surface of the wire receiving part by providing a curve geometry on its way from the release position to the strain relief position.
  • the core receiving part can be inserted together with the data transmission cable in an insertion direction into the cable receptacle of the plug connector. It is advantageous if the thrust surface of the at least one strain relief part forms a wedge surface aligned obliquely to the insertion direction of the wire receiving part.
  • the at least one strain relief part thus acts in the manner of a wedge thrust on the core receiving part, which can be subjected to a shearing force via the wedge surface and the associated contact surface.
  • the at least one strain relief part is preferably movably mounted on the housing of the electrical socket.
  • the at least one strain relief part is mounted in a linearly displaceable manner on the housing of the electrical socket.
  • the at least one strain relief part can be inserted in a straight line into the cable receptacle.
  • the guide elements are preferably designed as guide grooves and guide ribs, the guide grooves being designed to complement the guide ribs and the guide ribs being slidably received in each case by a guide groove.
  • the direction of movement of the at least one strain relief part is aligned perpendicularly to the direction of insertion of the core receiving part.
  • the at least one strain relief part has a locking surface against which the wire receiving part rests in the final assembly position.
  • the locking surface secures the wire receiving part in its final assembly position. The wire receiving part is thus held immovably in its final assembly position.
  • the locking surface is favorably aligned perpendicular to the direction of insertion of the wire receiving part.
  • the at least one strain relief part has a strain relief surface that can be placed against the data transmission cable on its end face.
  • the strain relief part can exert a pressing force on the data transmission cable via the strain relief surface when the strain relief part assumes its strain relief position.
  • the strain relief surface is designed in the shape of an arc, in particular in the shape of a circular arc.
  • the at least one strain relief part has at least one tool contact element for contacting an auxiliary tool for moving the strain relief part from the release position into the strain relief position.
  • Pliers can be used as an auxiliary tool, for example, or a screwdriver, for example, which can be positioned with its tip on the tool contact element in order to exert a force on the strain relief part so that it is moved from the release position into the strain relief position.
  • the at least one tool contact element can be designed, for example, in the form of an elevation, a depression, an opening, or for example in the form of an end surface of the strain relief part, in particular in the form of a flat end surface.
  • a particularly cost-effective production of the electrical socket can be achieved in that the at least one strain relief part consists of a plastic material.
  • the electrical socket has two strain relief parts.
  • the two strain relief parts can each be moved from a release position, in which they do not impede the insertion of the core receiving part together with the data transmission cable into the cable receptacle, into a strain relief position in which they dip into the cable receptacle and intercept external forces and moments acting on the data transmission cable.
  • the two strain relief parts can each be inserted into the cable receptacle through an opening in the housing.
  • the housing of the electrical socket has openings in the area of the cable holder, through which the strain relief parts can be inserted into the cable holder.
  • the two strain relief parts are opposite one another and accommodate the data transmission cable between them in the strain relief position.
  • the two strain relief parts can be moved in opposite directions from their release position to their strain relief position, i.e. the two strain relief parts can be moved towards one another during the transition from the release position to the strain relief position in order to receive the data transmission cable arranged in the cable holder in the strain relief position between them and from to apply a pressing force to opposite sides.
  • the two strain relief parts can be moved simultaneously from their release position into their strain relief position, preferably with the help of an auxiliary tool, for example parallel-closing pliers, which engage with their jaws on an end face of a strain relief part. While moving out of her Release position in their strain relief position, the strain relief parts move the wire receiving part from the pre-assembly position to the final assembly position. If the strain relief parts assume their strain relief position, they set the wire receiving part in the final assembly position.
