Definitions

  • the invention relates to a device for receiving an electrical or electronic component, in particular a relay socket for receiving a relay, comprising a base body with a receptacle for the component, wherein the receptacle in particular has at least two electronic connections for the component, wherein the device further comprises at least one pair of connection terminals connected to the two electronic connections, wherein the pair of connection terminals comprises a first connection terminal for a first connection wire and a second connection terminal for a second connection wire, wherein the first connection terminal is spaced from the receptacle by a first distance in a first direction.
  • Relay sockets for mounting on a mounting rail have been known for many years and are largely standardized mass products. Such relay sockets are typically mounted on mounting rails in control cabinets and are used in particular to control machines, industrial plants or building services, etc.
  • a relay socket comprises at least two connection terminals, which can be designed as screw terminals, tension spring terminals or leg spring terminals, for example. Leg spring terminals are also called direct connection terminals because they enable the direct connection of a rigid wire or a wire with a ferrule.
  • a clamping body comprises locking means for locking the clamping body onto a mounting rail.
  • the clamping body comprises a substantially rectangular recess into which a relay module can be inserted.
  • the relay module is secured to the clamping body by a substantially U-shaped swivel bracket, which has two longitudinal legs and a base leg aligned at right angles to the two longitudinal legs.
  • the clamping body is provided on its upper side with several pairs of connection openings for connecting external conductors.
  • the WO 2016/062809 A1 discloses an electronic module which has a base housing with a relay inserted from the top.
  • the electronic modules each have a base housing with several connection terminals arranged therein.
  • the EN 10 2012 010391 A1 shows an electrical connection module, which can be designed as a relay socket, with several connection terminals, which can be inserted into module receptacles of a module housing by means of a snap-in connection.
  • control cabinets When electrical installations are renovated or expanded, relays in the control cabinets or similar are replaced and/or supplemented. Typically, the total number of relays increases as the electrical installations become more complex. In order to cope with such developments, control cabinets are preferably oversized in new installations. However, the oversizing takes place in the Tension between the price and space requirements of a larger control cabinet and a predicted increase in the number of relays over the years. For these reasons, the control cabinets are being evaluated with regard to a total service life, which can last for several decades, are often initially dimensioned too small, so that retrofitting with additional relays is only possible to a limited extent.
  • the object of the invention is to provide a device belonging to the technical field mentioned at the outset for receiving an electrical or electronic component, which is designed to be particularly compact.
  • the second connection terminal is spaced from the receptacle by a second distance in the first direction, the first distance and the second distance being different.
  • the pair of connection terminals is designed as a plug-in unit which can be inserted, in particular snapped into, the base body, and the relay socket comprises a further pair of connection terminals in a second direction.
  • the base body preferably comprises at least two regions, a first region comprising the at least one pair of connection terminals and a second region adjoining the first region, comprising the receptacle for the component, in particular the relay.
  • the distance in question is determined by the shortest connecting line between the first connection terminal and the module holder, i.e. in particular by the Euclidean distance.
  • the receptacle for the component is preferably defined by a surface, typically a rectangular surface, in which the component can be accommodated.
  • the receptacle is therefore preferably understood to be the surface, in particular the flat surface, of the device in which the at least two electronic connections are located.
  • the preferably flat surface of the receptacle for the module has a first edge and a second edge parallel to the first edge as well as a third edge and a fourth edge parallel to the third edge, wherein the first edge and the third edge have different directions and are in particular aligned at right angles to each other.
  • the connection terminal pairs are preferably located between a first plane in which the first edge lies and which is perpendicular to the surface, and a second plane in which the second edge lies and which is perpendicular to the surface.
  • the distance is preferably measured from a center of the connection terminal.
  • the center of the connection terminal is preferably defined by a center point of an entry opening of the connection terminal into which a connection wire can be inserted.
  • Both the first distance and the second distance are measured along the same direction, namely the first direction, so that the distance vectors of the two distances differ only in magnitude.
  • distance difference is understood to be the amount of the difference between the first distance and the second distance.
  • the pair of connection terminals refers to two connection terminals (the first and the second connection terminal) which are related to each other.
  • the first connection terminal can be designed as the positive pole and the second connection terminal as the corresponding negative pole.
  • the two connection terminals can close a circuit, so that the first connection terminal and the second connection terminal can close or interrupt a circuit.
  • connection terminals of the connection terminal pairs each have the same distance from the component's receptacle, in particular the relay receptacle. Because the distance between the two connection terminals of the connection terminal pair and the receptacle is different according to the invention, a more compact design of the device can be achieved in a direction different from the first direction. In particular, the width of the device or the base body can be reduced in a second direction oriented at right angles to the first direction. In order to save material and space, several connection terminal pairs can be arranged in a zigzag shape, for example, with the second connection terminal of the connection terminal pairs having a smaller distance from the receptacle than the first connection terminals.
  • connection terminal pairs with a smaller width in the second direction can be pushed together in the second direction in comparison with the known embodiments. Even small differences in the distances can be sufficient to achieve the advantage.
  • the distance difference can be selected such that a pair of connection terminals in the second direction can have a width which, for example, corresponds to twice the diameter of a connection terminal opening.
  • Relay bases are typically mounted on mounting rails. Only a limited number of relay bases can be mounted on a mounting rail. A smaller overall width of the relay base means that a larger number of relay bases can be mounted on a mounting rail.
  • the fact that the relay base now has an overall width in the second direction which, when the relay is installed, corresponds to the relay width in the second direction, optimizes the space required.
  • the mounting rail is preferably oriented at right angles to the first direction, in the second direction.
  • the device according to the invention can be used in vehicle construction, in particular in automobile construction or the like.
  • the component can therefore also be designed as a circuit breaker, fuse, sensor, etc.
  • the electronic connections for the module, in particular for the relay, are preferably designed as sockets. This means that a relay with plug connections can be installed easily by plugging the relay with the plug connections into the socket of the receptacle.
  • the electronic connections can also be omitted.
  • the module can also be connected via separate cables.
  • the first connection terminal and the second connection terminal are preferably arranged one behind the other in the first direction.
  • the term "one behind the other" means that in the arrangement of the first and second connection terminals, a total width of the two connection terminal openings in the second direction is smaller than the sum of the diameters of the two connection terminal openings.
  • the distance difference preferably has an amount that is equal to or greater than the diameter of a connection terminal opening of the first or second connection terminal.
  • the first connection terminal and the second connection terminal can ideally be aligned in the first direction, so that the smallest possible construction width can be achieved in the second direction.
  • the two connection terminals can also be arranged slightly offset in relation to the first direction, in particular if this is advantageous for structural reasons, for example.
  • the arrangement behind one another can also be dispensed with, especially if, for example, a zigzag arrangement is chosen, in which a total width of a pair of terminals in the second direction corresponds to twice the diameter of a terminal opening (see above).
  • the first connection terminal of the connection terminal pair comprises a spring for clamping the connection wire.
  • the use of the spring has the advantage that it enables the connection wire to be attached without tools. Furthermore, it enables a compact design to be achieved, particularly compared to the known screw terminals.
  • another fastening technique for the connecting wire can be provided instead of the spring, in particular for example a screw clamp or the like.
  • Other techniques are known to the person skilled in the art.
  • the spring is preferably designed as a leg spring with a first and a second flank, the first flank being fixed and the second flank protruding resiliently into a receiving space for the connecting wire to clamp the connecting wire.
  • the receiving space is the space that is taken up by the connecting wire within the connection terminal when the connecting wire is attached.
  • the leg spring is particularly preferred because it allows a connecting wire to be attached directly and without opening a clamping point.
  • the leg spring is also inexpensive to manufacture.
  • the second flank of the leg spring is aligned in the direction of insertion of the connecting wire towards the connecting wire so that a clamping effect is achieved in the opposite direction.
  • springs in particular tension springs or similar.
  • Other types of springs are known to those skilled in the art.
  • the leg spring is preferably made of metal, in particular of a metal alloy.
  • the leg spring is particularly preferably made of a rust-proof material, in particular a steel alloy.
  • suitable plastics or composite materials can also be used.
  • the expert is aware of other suitable materials for the leg spring.
  • the second flank when the connecting wire is clamped by the second flank, the second flank can be moved at least partially out of the receiving space.
  • This enables the connecting terminal to be opened and the connecting wire to be released.
  • the second flank can be pressed back against the spring force.
  • the first flank can be released or moved from the fixed position.
  • connection terminal can be designed in such a way that the connection wire can be removed from the connection terminal without releasing the spring, for example by a sufficiently large pulling force that exceeds the clamping effect of the second flank.
  • a guide for the connection wire can also be designed to be movable so that the clamping effect of the spring can be deactivated.
  • a channel is arranged in the area of the first spring connection terminal, via which the second flank can be moved at least partially out of the receiving space by means of a rod-shaped element.
  • the channel is preferably arranged in such a way that it runs at an acute angle towards the second flank when the connecting wire is clamped by the second flank. This ensures that the second flank with the rod-shaped element can be released from the connecting wire with relatively little effort and that the clamping force of the leg spring can be selected to be relatively large.
  • the channel is preferably dimensioned in such a way that the rod-shaped element does not enter the receiving space. This prevents a clamping effect from being achieved between the rod-shaped element and the connecting wire, which could prevent the connecting wire from being removed.
  • the channel can, for example, have a stop for the rod-shaped element.
  • the channel can be omitted.
  • a permanently installed push button or something similar can be provided, with which the leg spring can be released.

  • the channels can also be arranged differently.
  • the two channels can also enclose the connection terminals in the first direction.
  • the channels have a channel width in the second direction, with the first and second connection terminals being offset by one channel width with respect to the first direction.
  • the channel openings can be arranged next to each other with respect to the first direction. This also achieves a compact design in the first direction.
  • the channels can also be arranged differently.
  • the two channels can also be arranged exactly one behind the other in the first direction, which allows the one construction width to be further reduced in the second direction.
  • a single leg spring could be provided, with the first leg extending into the receiving space of the first connection terminal and the second leg extending into the receiving space of the second connection terminal.
  • the leg spring would be made of a non-conductive material.
  • Other possible arrangements of the channels and the connection terminals are also known to the person skilled in the art.
  • the second terminal is designed analogously to the first terminal.
  • the second terminal and the first terminal are preferably designed essentially identically. This results in a particularly simple pair of terminals. "Essentially” means that the two terminals match in terms of the technically necessary features. However, differences can arise due to manufacturing, so that, for example, an asymmetrical reinforcing rib between the two
  • connection terminals Furthermore, a housing can be provided for the two connection terminals, which in subordinate aspects has asymmetrical features, such as a product number, asymmetrical seams between individual parts or the like, which, however, have no influence on the function.
  • the first connection terminal and the second connection terminal can also be technically designed differently.
  • the channels can have different angles to the first flank.
  • the receiving space of the first connection terminal can differ from that of the second connection terminal.
  • the first connection terminal is arranged point-symmetrically to the second connection terminal.
  • This arrangement has the advantage that a compact design can be achieved.
  • the channels of the first and second connection terminal can be arranged next to each other and between the two connection terminals, a particularly compact design is achieved.
  • the point symmetry relates to the technically essential features of the connection terminals, in particular preferably not to manufacturing-related features.
  • the essential features include the arrangements of the connection terminal openings, the receiving spaces and the channels.
  • connection terminals can also be arranged in a mirror image with regard to the essential features.
  • the pair of connection terminals with the first connection terminal and the second connection terminal is designed as a separate unit from the base body.
  • connection terminals can also be designed as a separate unit from the base body.
  • several pairs of connection terminals can be connected, for example, via predetermined breaking points, so that a number of pairs of connection terminals can be separated from the several pairs of connection terminals as required.
  • the pair of connecting terminals is designed as a plug-in unit which can be inserted into the base body, in particular can be snapped into place. This further simplifies the manufacture of the device.
  • cover plates can also be provided for the slots in the base body, which can be used to cover slots not occupied by pairs of connecting terminals.
