Definitions

  • the present invention relates to an expansion connection module for connection to at least two coil terminals of an electromagnetic switching device, in particular a contactor.
  • a voltage must be applied to the drive, for example the contactor drive.
  • the drive for example the contactor drive.
  • contactors can be combined in different ways with other switching devices, it may happen that the coil terminals are difficult to access. Sometimes these coil terminals are hidden, so that they are provided again at other locations of the contactor housing. This implies an expansion of the coil terminals within the contactor, which is complicated and costly and whereby the contactor can only be used for a specific purpose.
  • the coil terminals are located adjacent to the main or auxiliary circuit terminals for the coil terminal to be accessible from the front, often at least one coil terminal is inaccessible when combined with other switchgear.
  • electromagnetic switching devices are known in which the coil terminals are located under the main conductor terminals. In such switching devices accessibility is further complicated due to the even more complex structure, especially when the main conductor is connected. At a Installation of additional switching devices, such as a circuit breaker and / or an overload relay, the coil terminals are hardly accessible in these cases.
  • the object of the invention is to make the coil terminals of an electromagnetic switching device flexible and easy to access. In particular, the fixed coil terminals should be flexibly expandable.
  • an expansion connection module for connection to at least two coil terminals of an electromagnetic switching device, in particular a contactor, comprising a housing, fastening means for attaching the expansion connection module to the electromagnetic switching device or to a switching unit adjacent to the electromagnetic switching device, at least two connection openings and at least two connection pieces assigned to the at least two connection openings for connecting voltage supply lines and at least two strands for electrically connecting the connection piece of the expansion connection module to the at least two coil connections of the electromagnetic switching device.
  • the expansion connection module is a type of adapter by which the coil terminals of the electromagnetic switching device are extended or placed at other, more accessible places.
  • the extension connection module can be easily mounted on or removed from the electromagnetic switching device by the fastening means.
  • the fastening means are advantageously for non-positive attachment of the expansion connection module to the electromagnetic switching device or to an electromagnetic switching device adjacent further switching unit formed.
  • the length of the strands can be designed differently and variably.
  • the strands are easy to bend electrical conductors.
  • the strands are very easy and quickly connected to the existing coil terminals of the electromagnetic switching device by their flexible design.
  • the expansion connection module can also be designed for connection to more than two coil terminals of an electromagnetic switching device.
  • the expansion connection module has a housing in which the connection openings and the connection openings associated with the connecting pieces are arranged.
  • the connecting pieces are designed to be received by the power supply lines.
  • a power supply line can be passed through a respective connection opening to a connector and fixed by the respective connector fixed in the housing of the expansion connection module, so that the electromagnetic switching device can be supplied via the expansion connection module with a voltage.
  • the strands allow flexible mounting of the extension connection module to the electromagnetic switching device. After the expansion terminal module is fixed to the electromagnetic switching device or to a switching unit adjacent to the electromagnetic switching device, the strands are made long enough to reach the coil terminals of the electromagnetic switching device to supply the power to the electromagnetic switching device drive via the expansion terminal module enable.
  • the advantage of the extension connection module is that after the expansion connection module is attached to the electromagnetic switching device or to the switching unit adjacent to the electromagnetic switching device, the connection openings and the connection pieces of the extension connection module are easier to access and therefore faster Connection of the electromagnetic switching device to a power supply is enabled.
  • hard-to-access coil terminals of an electromagnetic switching device can be made easily accessible by redirecting the connections to the expansion connection module.
  • Another advantage of the expansion connection module is that the electromagnetic switching devices do not have to have integrated bypassing of the coil terminals, which would be complicated and expensive.
  • the extension connection module itself is a simple and cost-effective additional part, by which an extension of the coil terminals of an electromagnetic switching device, in particular a contactor, is made possible. The customer is free to use the electromagnetic switching device with or without extension of the coil connections, ie with or without the extension connection module. The necessity of using the extension connection module often results only in the assembly of the respective switching devices to a switching device unit or to a load feeder.
  • an expansion connection module in which the connecting pieces are designed as screw terminals or spring terminals. Both screw terminals and spring terminals have long been known in the cable connection technology.
  • the terminals are used for the detachable connection of electrical conductors, here the power supply lines. Particular preference is given to using so-called cage clamps.
  • the mechanical fixation of the respective power supply line by a screw or a spring is easy to carry out.
  • the power supply lines are connected to an electrical conductor within the expansion port module and thus electrically connected to the strands of the expansion port module.
  • a frictional attachment of the expansion connection module to the electromagnetic switching device or to the adjacent to the electromagnetic switching device switching unit can be designed in various ways. Such are, for example SSenbefest Trenten conceivable. Even cohesive connections, such as adhesive joints, are possible.
  • an expansion connection module is preferred, in which the fastening means of the expansion connection module have snap connection elements. Snap-in connectors enable quick assembly and disassembly of the expansion port module to the electromagnetic switchgear or adjacent control unit.
  • the expansion connection module snap-on hooks, which engage releasably in corresponding receptacles, ie undercuts, depressions, etc., of the switching device or the adjacent switching unit and thus fix the expansion connection module.
  • the extension connection module can also be fastened in a form-fitting manner to the electromagnetic switching device or to the switching unit adjacent to the electromagnetic switching device. This creates a particularly good fixation of the expansion connection module.
  • a further advantageous embodiment of the expansion connection module provides that at least two connection openings of the expansion connection module are arranged on one side of the extension connection module.
  • the connection openings may be provided on different sides of the expansion port module.
  • the housing of the expansion connection module has a cover.

  • an expansion connection module which has at least two feedthroughs for opening the connection pieces, in particular the at least two spring clips, by means of an actuatable tool that can be passed through is preferred.
  • each connection opening or each connection piece is assigned its own implementation.
  • connection openings can have different shapes and sizes. This is particularly conceivable if the expansion connection module has a multiplicity of connections. For example, several electromagnetic switching devices can also be connected to the one expansion connection module. In particular, if only one electromagnetic switching device is to be expanded by the extension connection module, it is advantageous if the cross section of the connection openings is the same.
  • the strands are led out of the interior of the expansion terminal module and can be attached to the coil terminals of the electromagnetic switching device for electrical connection by means of a simple wiring. It may be desired that the strands should be guided along a certain path. This can be realized by running the strands in special guides.
