Definitions

  • the invention relates to an installation system made up of cables with plugs and connection centers for permanent yet flexible switching connections, which also produce plug connections to several lines.
  • An installation quick coupling for such a system is known (DE-AS 27 41 798).
  • the known installation quick coupling works with a distributor to which input plugs with socket contacts can be plugged in for supply.
  • An outlet socket with plug contact sockets is provided in the current passage, to which a plug with plug contact pins of a coupling line can be inserted.
  • Branches for energy supply are made possible by means of outlet plug-in receptacles on the back of the distributor for AC and three-phase feeders. The outlets are offset so that an approximately symmetrical load can be achieved.
  • the outgoing plug receptacles are provided with socket contacts and the assigned outgoing plugs with contact tongues. To ensure that no live parts can be touched, reliable coding is required.
  • socket contact plugs can also be connected to a tongue contact plug via a line as a ready-to-use coupling line.
  • plug-in components can be inserted into the cable run. (For example, according to DE-AS 24 15 727, DE-OS 27 12 723). What these and similar systems have in common is that wiring work is saved on the construction site. Such installation systems, which also enable electrical switching without wiring work due to plug-in components for switching functions, cause many contact resistances. They are particularly numerous if each socket can be plugged in individually (DE-OS 27 12 723).
  • these contact resistances increase losses and heating, and on the other hand, they accumulate sources of error. If one follows the current path from a conductor via the plug-in components of the known type, the following transition resistances result, for example: from the conductor to a connection point in a plug, from socket contacts to contact pins or tongues, from the contact pins or tongues to the connection contact of a branching element. . tes in a plug-in component, possibly a branch connection, i.e. a connection point in a branching element, is present from the connection of the branching element to a socket contact, from the socket contact to a contact pin or tongue, from the connection of the contact pin or tongue finally to the conductor in Branch.
  • the current path in such a single branch thus has seven to eight contact resistances. With conventional wiring in standard wall plaster boxes there is a single transition resistance in the connection terminal.
  • the number of transition resistances in the plug-in systems increases with the number of conductors as a factor.
  • the invention has for its object to develop an installation system which is suitable for permanent or stationary operation, which is flexible, yet safe and in which the number of contact resistances is drastically reduced.
  • This installation system is flexible and secure since it is pluggable, but the sockets in the connection center are recessed. It is essential that this installation system needs only three contact resistances for a branch: from the conductor to the connection point for the contact rails, from the tongues of the contact rail to socket contacts of outgoing plugs, from the socket contacts to the connection point of the branch conductor. The same can be seen in the passage of current from connection center to connection center.
  • contact rails in a common housing are arranged so offset with respect to their course and the arrangement of plug receptacles on the back of the housing that in a multi-phase system each is connected to different phase conductors. This creates an approximately uniform load. It also makes it possible to make do with plugs of a structure with three-pin plugs.
  • the protective collar and the assigned plug can form an optical coding and / or a mechanical coding by means of unmistakable means. This makes handling easier.
  • the conductors of a line can be held on the contact rails of the connection center by a clamp bracket.
  • they can be crimped on, for example.
  • flaps of the rails or the rails themselves are bent around the conductor to be connected and pressed on.
  • Such a connection is simple to manufacture and can be machined on an industrial scale.
  • the housing of the connection center can, in principle, be a cuboid-shaped structure that receives a connecting line on one end face, at the other end of which a plug is attached, and forms a plug receptacle for connection to all contact rails on an opposite end face, and which is provided with latching members.
  • the latching promotes safe continuous operation. It can be designed so that it can be used with tools or can solve by hand.
  • connection center can enable branches for alternating current and for three-phase current if, in addition to plug receptacles for alternating current plugs, those for three-phase plugs are also formed on the back of the housing. Safety in continuous operation is promoted if the plugs assigned to the plug receptacles are provided with resilient flat contact sockets.
  • the installation system can be further developed for switching functions. It is then modified in such a way that at least one line with two conductors on an interrupted contact rail is each connected to a conductor on a contact rail piece and that these pieces of the interrupted contact rail and further contact rails open at their ends with plug receptacles for connection to all contact rails.
  • the line to an interrupted contact rail forms a switching line, to the free end of which a switch of the usual type can be connected.
  • a total of an adapter plug is thus formed, to the switching line of which a switch can be connected.
  • This adapter plug also requires relatively little transition resistance.
  • the means for the branches are not burdened by the requirements of the switching elements in the number of contact resistances.
  • the connector receptacles for connection to all contact rails of the intermediate connector can be provided with latching members.
  • the number of contact resistances of the intermediate connector is further reduced if only one connector receptacle is designed for connection to all contact rails and if a line is held opposite, the conductors of which are held directly on the contact rails, in particular by means of a clamp. Understandably you can also use simple conductors instead of contact rails.
  • a connection center with an inserted adapter plug fulfills branch and switching functions.
  • the switching, alternating, series and cross-connections known in installation technology can be implemented by means of a corresponding switching line and interruption points of the contact rails in the adapter plug.
  • a bracket with means for quick fastening can be arranged on the housing of the connection center in order to be able to fasten the installation system quickly to holding rails or other suspension means.
  • Such support rails can be support frames in false ceilings or in other cavities.
  • the bracket can advantageously be formed substantially U-shaped, one leg of which is connected to the housing and in which threaded openings are formed, and the other leg of which is penetrated by a wing screw which fits into one of the threaded openings.
  • Plug-in installation systems with switching functions which work with additional conductors to which voltage is applied for switching (DE-AS 24 15 727, DE-OS 27 12 723). If the control switch contact of a control pushbutton module is actuated in such a known system, a current flows through the contact from the supply current line to the switching line and via an excitation coil of a relay of a switching module and from there via the supply line. This current can then be used to excite a relay which closes a contact, as a result of which a supply current line is now switched through from the input to the output of the switching module. As a result, the system output of the switch module carries current and the electrical devices connected downstream of it are then switched on (DE-AS 24 15 727).
  • the installation system according to the invention manages without additional conductors and is much simpler.
  • FIG. 12 A broken contact rail of the connection center according to FIG. 1 is shown in FIG. 12.
  • the connection center 1 has contact rails 4 directly connected to the conductor 2 of a line 3.
  • Three contact rails can represent the phase conductors L1, L2 and L3 and two contact rails 4 the neutral conductor N or the protective conductor PE.
  • the contact rails 4 each form a plurality of tongues 5, according to FIG. 2, which can be coupled to socket contacts in socket plugs.
  • the housing of the connection center 1 consists of two housing shells 6. The housing receives the tongues 5 in a recessed manner in the plug receptacles 7. It forms protective collars 8 that match the plugs.
  • At least one connector receptacle 7a according to FIG. 1 is designed as a connection to all contact rails.
  • the connector receptacles 7 there is only one phase for AC connection and three phases are accessible for three-phase connection. It is also possible to design a three-phase connection in such a way that either an AC plug or a three-phase plug can be inserted. Only both codes are to be provided in the socket.
  • the contact rails 4 are arranged in a common housing 6, 6 with respect to their course and the arrangement of connector receptacles 7 on the back of the housing so that in a multi-phase system each is connected to other phase conductors. This distributes the burden.
  • a suitable design of the contact rails 4 with respect to an offset arrangement of Connector receptacles 7 can be seen from an overview of FIGS. 1 and 3 for an embodiment. In FIG. 12, a contact rail 4 with tongues 5 formed on opposite sides is shown broken off.

  • a mechanical coding is formed by unmistakable means 10, grooves in the connector receptacle and matching webs in the connector.
  • the conductors 2 of the line 3 are connected directly to the contact rails 4 according to FIG. 1 by means of a clamp holder.
  • flaps or the rails themselves are bent and pressed around the conductor to be connected, which is known as crimping.
  • a connecting line 3 is connected to an end face, at the other end of which a plug 11 is fastened as a connecting plug, according to FIG. 4.
  • a plug receptacle 7a is formed for connection to all contact rails.
  • the plug receptacle 7a is provided with latching members 12, into which latching levers 13 of the plug core according to FIG. 4 can engage.
  • connection center On the back of the housing, according to FIG. 3, of the connection center, in addition to plug receptacles for AC plugs with a total of three contact members, those for three-phase plugs with a total of five contact members are also formed.

  • Such flat contact sockets 14 can be pushed onto the tongues 5 of the contact rails 4.
  • connection center 1 fulfills a distribution function, since plugs can be inserted as outgoing plugs on the back of the housing in the plug receptacles 7. Further connection centers can be plugged into the connector receptacle 7a for connection to all contact rails 4 with their connector according to FIG. 4.
  • FIG. 6 and the front view of FIG. 7 is designed as a three-pin outgoing connector, which accommodates only three flat contact sockets 14 in a unit housing 20, namely one for phase L1 and one further contact for neutral conductor N and protective contact PE. 6 can be inserted into the back of the connection center 1 according to FIG. 3.
