Definitions

  • the invention relates to an installation system made up of cables with a plug core and with a connection center for plug connections for flexible and permanent switching connections, in order to also produce plug connections to several branching lines, in detail according to the preamble of claim 1 and is based on FR-A-2 145 409 out.
  • FR-A1-2145 409 to connect contact rails to the conductors of a line, on which outlets for plug contacts are formed.
  • the contact rails enable through connections by being connectable to the conductors of an outgoing through line.
  • an outgoing line can be plugged into a contact rail.
  • Two outgoing lines can also be connected to individual contact rails.
  • An installation quick coupling is known (DE-B2-2 741 798) which 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 safety is increased by a protective collar.
  • the outlets are offset so that an approximately symmetrical load can be achieved.
  • plug contacts on the market that are used, for example, to connect lighting fixtures in fitted kitchens, which prevent live parts from being touched by the fact that the contact pins or contact tongues are also protected in envelopes, the associated socket contacts between the pins or tongues and their Intervene wrapping.
  • Such 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 (for example according to DE-B - 2 415 727, DE-A-2 712 723). 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-A-2712723).
  • 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 contact 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 in a plug-in component, possibly a branch connection, i.e. a connection point in a branching element, 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 the branch.
  • the current path in such a single branch thus has seven to eight contact resistances. With conventional wiring in conventional wall plugs, there is a single contact resistance in the connection terminal. The number of contact resistances in plug systems increases with the number of conductors as a factor.
  • the invention has for its object to develop an installation system for permanent or stationary operation, which is flexible, yet safe, in which the number of contact resistances is drastically reduced.
  • the conductors on one side of an imaginary through connection are designed as plug connections, but the conductors on the other side are directly connected.
  • the feedthrough functionally ensures the forwarding of all connection options.
  • the solution according to the invention enables contact rails with molded outlets in the manner of a comb to make do within a contact rail in a simple manner without additional contact resistance. There are no additional contact resistances from the downstream tongues of the connection center to other branch lines.
  • contact rails in a common housing are offset with respect to their course and the arrangement of plug receptacles on the back of the housing, so that in the case of a multi-phase system, connection is made 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 plug cores.
  • the protective collars and the associated plugs can form an optical coding due to their shape and / or mechanical coding due to the unmistakable means. This makes handling easier.
  • the housing of the connection center can be a cuboid-shaped structure that receives a connecting line on one end face, on the other end of which a connector is fastened, and forms a connector 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 solved with tools or 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. At least one line with two conductors can be connected to an interrupted contact rail, each with a conductor on a contact rail piece. These pieces of the interrupted contact rail and further contact rails can end at their ends with plug receptacles for connection to all contact rails.
  • the line to an interrupted contact rail forms a switching line, at 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 contact resistance.
  • the means for the feeders 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 elements.
  • the number of contact resistances of the intermediate plug is further reduced if only one plug 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 clamping bracket. Understandably, simple conductors can also be used instead of contact rails.
  • connection center with an inserted connector fulfills branch and switching functions.
  • the appropriate switching, changeover, series and cross-connections known in installation technology can be implemented by means of an appropriate switching line and break points of the contact rails in the adapter plug.
  • Plug-in installation systems with switching functions which work with additional conductors to which voltage is applied for switching (DE-B-2 415 727, DE-A-2 712 723).
  • a current flows via 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.
  • the system output of the switching module carries current and the electrical devices connected downstream of it are then switched on (DE-B-2 415 727).
  • the installation system according to the invention manages without additional conductors and is much simpler.
  • FIG. 12 shows, broken off, a contact rail of the connection center according to FIG. 1.
  • 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.

  • a suitable design of the contact rails 4 with regard to an offset arrangement of plug receptacles 7 can be seen from a summary of FIGS. 1 and 3 for an exemplary embodiment. In FIG. 12, a contact rail 4 with tongues 5 formed on opposite sides is shown broken off.
  • the protective collar 8 can form an optical coding through its shape or through the choice of color.
  • a mechanical coding is formed by means of unmistakability 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.
  • the housing of the connection center 1 according to FIG. 1 is essentially a cuboid-shaped structure, composed of two housing shells 6 made of insulating material.
  • a connecting line 3 is connected to one 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 plugs 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, also those for three-phase plugs with a total of five contact members are formed.
  • the plugs assigned to the plug receptacles 7 and 7a can advantageously be provided with resilient flat contact sockets 14, as shown in the plug 11 designed as a connecting plug according to FIG. 4, and in the plugs according to FIGS. 5, 6 and 7 as well as 8 and 9 .
  • 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 connecting plug according to FIG. 4.
  • FIG. 6 and the front view according to FIG. 7 is designed as a three-pole 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.
  • the correct connection is ensured by means of unmistakability 10, namely webs on the connector housing and associated grooves in the connector receptacle of the back of the connection center 1.
  • the plug according to FIG. 6 has a lever 13 for latching on the plug receptacle according to FIG. 3.
  • the line 3 accordingly takes up five conductors 2, in which the line 3 of the plug according to FIGS. 6 and 7 contains only three conductors 2.

  • the adapter plug can be plugged into the distribution center directly or via a connecting cable. It can have its own holding means, as described in the connection center.
  • the number of contact resistances of the intermediate connector according to FIG. 10 is further reduced if only one connector receptacle or one connector is designed for connection to all contact rails, as illustrated in FIG. 11. This eliminates the contact resistance between the adapter plug and the outgoing plug.
  • the plug 7b can again accommodate flat contact sockets 14 for connection to all contact rails 4. Opposite a line 33 is introduced, the conductors 2 are held directly on the contact rails 4 by clamping bracket.
  • the intermediate connector according to FIG. 10 and the combination connector according to FIG. 11 can also simply contain conductors made of electrically conductive material instead of rails 4.
