    Description TECHNICAL FIELD The present invention relates to a modular terminal for clamping strands and hard wires for sockets according to the preamble of claim 1.
    Background Art [0002] Sockets commonly used nowadays consist of a bezel and a socket insert. In a socket insert usually one or more sockets for power plugs, terminals for the electrical connection of the socket to a power line network and numerous electrically conductive fasteners between the sockets and the terminals are housed.
    Known sockets usually have a terminal with a multi-part complex structure, which includes a variety of plastic parts and bent or stamped metal parts for receiving a plug on the one hand and for connection to an electrical line network on the other.
    Such a clamp is usually made of a terminal cage, a clamp and, for example, a clamping screw, as is common in elevator terminals. Lifting clamps are excellently suited for clamping and electrical contacting of hard conductors as well as of strands.
    In practice, the handling of a clamping screw with regard to the time required for installation proves to be extremely disadvantageous with respect to embodiments of spring clamps.
    Spring clamps comprise, for example, a prestressable leaf spring instead of the clamping screw. However, they are only suitable for contacting hard cores by spring force. These are mechanically permanently and electrically safely clamped releasably in a holder profile with a spring mechanism. The connection is based on self-locking. For the contact, the spring lies flat on the wire. A re-release of the clamp connection is done by pulling the hard wire against the insertion direction with simultaneous back and forth turning of the electrical conductor. If you want to use strands instead of hard-core wire conductors, this will not work anymore. The strand splits already after a single clamping and wears out.
    From the telecommunications industry, terminals for preventing crosstalk are known to the person skilled in the art (EP 0 843 907 B1). These are due to the large number of connecting or individual wires to be contacted particularly filigree and accurately built, as described for example in DE 19938367 C2.
    Modular terminals for clamping of strands and / or hard wires for socket inserts to build one or more sockets with a simplified and greatly reduced set of items are following the principle of a modular system, not known.
    OBJECT OF THE INVENTION The invention solves the problem of providing a modular terminal for clamping strands and / or hard wires for sockets in order to overcome the disadvantages of the prior art. Solution to the Problem [0010] To achieve the object, the features according to claim 1.
    A terminal module according to the invention is particularly suitable for clamping a stranded wire as well as for clamping a hard core and / or a hartadrigen conductor and is modular as a module itself, so that it is particularly well suited as an element for an easy-to-handle modular principle for socket inserts.
    The technical terms ladder and strand are used in the context of the invention description consistent with the definition of conductor classes according to IEC 60228 and are intended to include both solid and stranded, as well as finely stranded and fine stranded conductor within the scope of the invention. Likewise, in the context of the invention, professional terms such as round-solid or sector-shaped einsträhtig, round-stranded or sector-shaped multi-stranded as well as "flexible" or "highly flexible" include.
    An inventive terminal module for a modular outlet has at one end a double cutting terminal for insulation displacement of a wire conductor and the other end a terminal for clamping at least one stranded conductor and / or wire conductor. The clamp comprises a double guide element and a double cutting clamp, wherein the double guide element and the double cutting clamp are integrally formed.
    In one embodiment of an inventive terminal module, the terminal is angularly tilted to the horizontal plane of the double cutting clamp arranged.
    For a particularly user-friendly handling of the socket insert when connecting the individual strands of a neutral conductor, an outer conductor and a grounding conductor to an electrical line network, a Winkelverkippung the terminal for double cutting terminal between 30 to 50 ° has resulted. A preferred angle is in the range of 35 to 45 °, with an angle of 45 ° has been found to be particularly suitable.
    In one embodiment of an inventive terminal module, the double cutting clamp and the terminal are integrally formed of sheet metal.
    The technical term sheet is used in the context of the description of the invention in accordance with the definition according to EN 10029 (formerly DIN 1543).
    The double-cutting terminal of an inventive terminal module is used for electrical contacting of a socket in a socket holder for a connector pin of an electrical power plug. For industrial and domestic use usually three-pin or five-pin power sockets are common, so usually in a three-pin power outlet three sockets in a socket holder and a five-pin power socket five sockets are housed. Furthermore, there are usually three sockets in a socket holder and one to three socket holders for single to triple sockets in a socket insert. In the case of three sockets, these three are each electrically connected to each other with a neutral wire, a phase wire and a grounding wire. Furthermore, the neutral wire, the phase wire and the grounding wire are each electrically connected to a terminal module by means of a double-cutting terminal with the wire conductors of an electrical installation network.
    The technical terms of a neutral or neutral wire, a phase wire or phase conductor and re-normalized outer wire or outer conductor and ground wire or grounding conductor are used within the scope of the invention description consistent with the respective valid standards of IEC and are in doubt the three different conductors of a three-wire system for represent an installation network.
    In one embodiment of an inventive terminal module, the terminal is designed as a one-piece spring element with two spring tongues. Each spring tongue has a cutting edge for clamping a strand and a release tongue per spring tongue. The clamp also has two strand guide elements, which are suitably shaped to form a double guide element. The double guide element comprises the possibility of independently clamping two strands independently of each other and electrically connecting them to one another at the same potential. The double guide element comprises two independently operable clamp solver for one strand guide element for clamping and loosening each of a stranded wire and / or a hartadrigen wire conductor. Furthermore, the double guide element comprises a holder for the integrally formed spring element. Such a holder can be realized for example by a plurality of punched holding tongues.
    A first press on a clamp release, which is in operative connection with a release tab, causes in a first step opening the clamp and facilitates the insertion of a strand in one of the two stranded guides of the double guide element.
    The Klemmlöser includes in the context of the invention, a terminal fork with two forks, a fork tines is in direct operative connection with the release tab and acts directly on them when pressing on the Klemmlöser. The insertion of the strand is facilitated in the context of the invention by the two forks, since these serve in addition to the strand guide as an additional lateral strand guide and prevent unwanted splitting of the strand. This has the advantage that even very flexible wire strands can be used as electrical conductors for an electrical installation network.
    After pressing and subsequent force solution to a Lösezungen one of the two spring tongues of the spring element, the cutting edge of one of the two spring tongues clamps the strand against the respective strand guide of the double guide element and contacted the strand in this way electrically with simultaneous fixation by means of clamping.
    For the purposes of the invention, the terminal fork of the clamp solver is ideally shaped sickle-shaped. This has the advantage that at a second press on the clamp release a jammed strand is formed by the sickle shape during loosening again almost stranded. This is due to the fact that when loosening the strand, which was flattened by the clamping and / or pinching itself, this is enclosed by the two prongs of crescent-shaped terminal fork and shaped loosely again when loosening in Litzenquerschnitt again.
    For the purposes of the invention, the cutting edge is provided with a single, double or multiple cutting edge.
    An inventive terminal module is also suitable for clamping a stranded wire as well as for clamping a hard core as an electrical conductor for the connection of a modular socket insert to an installation network. In the context of the invention, a hard core can also be designed as a conductor known to the person skilled in the art as a rigid conductor. Likewise, within the scope of the invention, a flexible conductor, for example a stranded wire, can be used by the person skilled in the art as a conductor. The conductor is used for electrical conduction and ideally has a very low electrical resistance.
    In the context of the invention, a socket holder with two sockets for receiving a two-pin connector is possible and should not be excluded within the scope of the invention. This socket holder is also to be understood as a (modular element within the meaning of the invention.
    In an inventive terminal module for sockets with a socket holder, the first socket to the neutral conductor, the second socket to the protective conductor, that is electrically grounded and the third socket is connected to the outer conductor of an electrical installation network.
    In an inventive terminal module for sockets with multiple socket holders, for example, 2, 3, 4 or a larger number of socket holders, each first socket with a common neutral conductor, every second socket with a common protective conductor and every third socket with a common outer conductor each connected to each other.
    The common neutral conductor, the common protective conductor and the common outer conductor are ideally each formed in one piece. Furthermore, the common neutral conductor, the common protective conductor and the common external conductor are each connected to the neutral conductor, to the protective conductor and to the external conductor of the electrical installation network in a manner known to the person skilled in the art and suitable.
    For the purposes of the invention, a larger number of socket holders together with the novel clamping modules particularly advantageous for multiple sockets and power strips with a variety of sockets. Such multiple sockets can be designed as 2-fold, 3-way or socket strips also x-fold sockets, with a value for x, for which applies 4 <x <30.
    An inventive terminal module for a modular outlet is designed such that it is compatible with other elements for a modular outlet in the context of the modular principle for socket inserts and can be particularly economical to produce such x-fold sockets.
    In the context of the invention, such further elements for a modular outlet, for example, a timer, a remote circuit, a software-based remote control in combination with a mobile phone, the person skilled in the art also known as a smartphone app, or an electronic central control module for intelligent networking, Control and / or control of sockets.
