Definitions

  • the invention relates to a distributor block, that is to say an assembly or an electrical device with means for multiple tapping (distribution) of a potential supplied on one connection side.
  • Manifold blocks or manifold assemblies are well known in the art.
  • Manifold blocks are used in electrical installation, for example in so-called distribution boxes for house connection or the like.
  • distribution boxes for house connection or the like.
  • a supplied potential is forwarded to several points, thus also when connecting electrical systems, for example in industry.
  • a distribution box without limitation of the general application possibility is always assumed by a distribution box as a mounting location.
  • Manifolds are usually just one device of many devices that are mounted in distribution boxes for electrical installation. Even if no or only a few other components are to be provided in the same distribution box, it is often necessary to place a plurality of distribution blocks. Thus, in addition to compliance with the safety regulations for electrical equipment and the fulfillment of the relevant standards, the size of a distributor block is a decisive criterion for its usability in practice. In terms of size, especially the width of the construction is in the foreground. The smaller the width, the more manifold blocks can be placed side by side at the mounting location.
  • electrical equipment for electrical installation or for electrical or electronic equipment on a mounting unit for example, a DIN rail mounted. With a small width so far so a higher packing density of distribution blocks and other electrical Devices or a higher packing density of distribution blocks on a DIN rail possible.
  • a determining factor for the width of a distribution block is the maximum supply current that can be provided.
  • the current which the conductor can transport safely, that is, for example, without the risk of overheating, depends directly on the conductor cross-section.
  • a hole with a diameter of 15 mm is required.
  • connection blocks usually have only one connection point for an incoming conductor on their connection side in favor of a small overall width.
  • Manifold blocks with two connection points have these holes formed in one plane or in slightly different planes but at least side by side on the connection side.
  • the bores are normally formed in a clamp body encompassed by the distributor block. To the outer sides of the clamp body but also between adjacent holes must remain a specified by standards wall thickness, so that the relevant provisions regarding the reliability and serviceability of such a distribution block are met.
  • a clamp with a cuboid clamp body which has at its end faces in each case an insertion opening for the connection of electrical conductors, wherein on the clamp body an encompassing this elevator clamp is mounted, so that by means of the elevator clamp the bottom of the clamp body results as an additional contact point.
  • a disadvantage of known distribution blocks with two connection points on the connection side is accordingly that either the width increases to unfavorable extent or that only holes with a comparatively small diameter are possible as connection points, so that the manifold block only Amperages can be supplied below a predetermined by the bore diameter threshold.
  • the starting point is a distributor block having at least one or exactly one connection side and a first and second connection point provided there, the first and second connection points permitting the detachable connection of an electrical conductor in each case.
  • This is characterized in particular by a movable against an underside of a clamping body fixing part and a remaining between a stop and an upper side of the fixing part gap.
  • the clamping body namely its side facing the connection side, is the location of the first connection point.
  • the space between the stop and the top of the fixing part is the location of the second connection point.
  • the proposed distribution block has a first and second connection point and allows at both connection points the connection of electrical conductors and with such an electrical conductor, a supply of electric current with considerable current, for example 250 amps.
  • the width of the distributor block is essentially determined by the width of the clamping body arranged in a housing of the distributor block. After the fixing part is movable against a lower side of the clamping body, the two connection points lie one above the other in two planes, so that the requirements with regard to the necessary wall thicknesses in the clamping body or the requirements with respect to necessary safety distances can be maintained in each level.
  • the manageability or the possible uses of the distributor block are improved in that the distributor block has two connection points for electrical conductors with a comparatively large cross section, ie a cross section which allows the transmission of higher currents, for example 250 amperes, and that the distributor block nevertheless has a comparatively small size Has width.
  • more distributor blocks can be arranged next to one another in comparison with distributor blocks with a larger overall width.
  • the first connection point has a circular insertion opening for connecting electrical conductors in the form of so-called circular conductors and / or that the second connection point has a rectangular insertion opening for connecting electrical conductors in the form of so-called flat conductors.
  • the distributor block is suitable without modification regardless of a geometry of the respective incoming cable for the connection of such a cable and for the distribution of the potential supplied thereto.
  • the connection of flat conductors is not possible or at least not yet possible. Accordingly, the embodiment with two connection points, each with a different geometry of the insertion openings therein, expands the application spectrum of the distribution block to rectangular geometries of incoming cables.
  • the electrically conductive connection of the first and second connection point is considered that an underside of the clamping body acts as a stop which forms the second connection point with the fixing part.
  • the distribution block has means for independently actuating the first and second connection points from an upper side of the distribution block, the accessibility of such activation means the connection of an incoming electrical conductor to one of the two connection points is relatively easy and clear, and also takes place in a familiar orientation for the installer / operating direction.
  • the actuation means can be actuated independently of one another, for example, a conductor can be connected to the second connection location, while a conductor (for example a bridge) already connected to the first connection location remains in electrically conductive contact with the clamp body.
  • fixing part of the distributor block comprises means for moving the fixing part in the direction of the clamping body, that is to move against the actuating direction of the actuating means or the actuating means.
  • the means or means for moving the fixing part thus directs or deflects the action of the or each actuating means opposite to the actuating direction.
  • As a means of such moving the fixing part is basically a lever mechanism into consideration, wherein on the lever on one side of the fulcrum of the attack or the actuating means and wherein the lever is combined on the other side of the fulcrum with the fixing part.
  • a spring mechanism into consideration for example, in which a spring presses the fixing member against the underside of the clamping body when a locking of the spring or the fixing part is released.
  • the distributor block has screws as means for moving the fixing member against the clamping body, which are guided in the clamping body in two holes formed therein and engage with their free ends in the fixing part in two threaded holes formed there, is a particularly simple way to the above outlined deflection given.
  • the screws in particular exactly two screws, are guided in two holes in the clamping body. Either the inner surface of the holes or a corresponding portion of the screw pin is thread-free, so that the screws are freely rotatable in the holes.
  • the holes act as a bearing sleeve for the screws. At least the free ends of the screw pins have a thread and thus engage in two threaded holes formed in the fixing part.
  • the fixing part is rotatably supported by the simultaneous support with two screws in the housing of the manifold block. Even if one of the two screws should not be in engagement with the respective threaded hole in the fixing part, the housing of the distributor block causes such a rotationally fixed bearing.
  • the fixing part is moved with its affected by the movement of the screw portion in the axial direction of the screw pin in the direction of the underside of the clamping body. This direction of movement is opposite to the direction of actuation with a screwdriver or the like for rotating the screw. If both screws are actuated alternately, the fixing member is moved in approximately parallel alignment with the underside of the clamp body on this.
  • the distributor block has a bottom profile for detachable connection, in particular latching, with a mounting unit, in particular a DIN rail
  • the distributor block like other electrical appliances, for example clamps, automatic circuit breakers and the like, can be installed on such a mounting unit in a distribution box or the like to be assembled.
  • the manifold block When the manifold block has a stackable side profile (bay profile), the manifold block may be combined with other manifold blocks or other electrical devices having a same side profile, for example, a main line branch terminal of the assignee of the present invention or the like. Due to the combinability, it is possible to produce a dressing of, for example, a plurality of distributor blocks which form a unit even without being combined with an assembly unit and thus can be moved and positioned as a whole.

Due to the combinability, it is possible to produce a dressing of, for example, a plurality of distributor blocks which form a unit even without being combined with an assembly unit and thus can be moved and positioned as a whole.
  • the invention further relates to a system formed from manifold blocks of the type described here and below.
  • Such a system or such a group of two or more with one bridge electrically connected distributor blocks has the advantage that the supplied at one of the manifold blocks due to an electrical conductor connected there potential not only on the terminals of the output side of this distributor block but also on all output ports of all other covered by the system / group distribution blocks can be tapped.
  • the number of output-side connection options can thus be almost arbitrarily and in such a way by such a group or system formation Increase dependence on the respective needs of the installation situation.
  • a particularly simple situation for the electrically conductive connection of two or in each case two distributor blocks combined in one system or one group results if the electrically conductive connection between the first and the second distributor block is established by a bridge between the first connection point of the first distributor block and the first connection point of the first distributor block second distributor block or the second connection point of the first distributor block and the second connection point of the second distributor block.
  • the bridge thus always connects two quasi-identical connection points, either two first connection points or two second connection points.
  • preconfigured bridges can be used which each have an identical geometry at their contact points, ie either a circular or a rectangular cross-sectional contour.
  • the individual manifold blocks are combined with each other, for example via a lateral Anreih profile, results in a defined, always consistent distance between each two adjacent first or second connection points of juxtaposed manifold blocks. Due to the distance known so far of the connection points is also a necessary dimension of bridges for electrically conductive connection of the manifolds fixed.
  • the bridges can also be preconfigured in terms of their length dimensions and offered as accessories to the distribution block.
  • the installer has the advantage that the bridge is directly usable, and that unlike a bridge made of a piece of cable no attention must be paid to a proper cutting, a right bend, etc., so that electrically conductive connections between two or more manifold blocks can be produced quickly and with little effort.
  • FIG. 1 shows a perspective view of an embodiment of a generally designated 10 manifold block.
  • the distributor block 10 has two connection points, namely a first connection point 14 and a second connection point 16, on an input or connection side 12.

  • the circular insertion opening 20 allows the connection of round conductors on the manifold block 10.
  • the rectangular insertion opening 22 allows the connection of flat conductors.

  • Such a shape of the housing edge gives the distributor block 10 as a whole and especially in cooperation with the in the lateral plan view (see. FIG. 2 ) arcuate back or output side 18 and the likewise arcuate top an attractive visual appearance.
  • the distribution block sits so well in the hand and the edge-free or substantially edgeless surface avoids injuries.
  • the arcuate transition between the lower housing part and the upper housing part engages the edge-free side contour of the distributor block 10 and leads to almost organic forms.
  • the most downwardly projecting part of the upper housing part where the lower housing part as it were recessed groove-like acts as a natural axis of rotation for the upper housing part, for example when this is combined after insertion of the clamp body 24 with the lower housing part.
