  • the couplers are usually capacitive couplers, which are dimensioned so that the low-frequency network voltage of the power supply network is significantly reduced or even completely blocked and communication signals are passed largely unchanged.
  • Another problem with using the special nut described above is the need for a relatively large amount of space. In addition to the space for the special nut space for the second nut is required. At the same time, a minimum distance to the housing wall, in the present case usually a housing door, must remain. This installation space is not available in all installation situations.
  • connection of a BPL coupler to a NH fuse load bar it will be apparent to a person skilled in the art that the problem described above can arise in a wide variety of scenarios in which an electrical device is connected directly or via connection means of an electrical system a power supply network is to be connected.
  • the power supply network can both low voltage, i. AC voltages up to 1000V, as well as medium voltage, i. AC voltages above 1000V to 52 kV, lead.
  • the connection means need not necessarily be a screw connection, even if this has prevailed in the field of energy supply as a quasi standard. It is usually sufficient if the connection means is substantially prism-shaped, wherein the outer cross-section - to name just a few examples - can be round, hexagonal or square.
  • connection clamp consists of two legs, which are pivotable about a riveted axis. In a closed state, the connection terminal resembles a ring cable lug. At the opposite end of the riveted axis a survey on one leg and a corresponding recess are formed on the other leg, which engage in the closed state and hold the connection terminal in the closed state.
  • the US 5,879,202 A and the EP 1 675 221 A1 disclose battery terminals that allow the connection of a connection cable to a battery post.
  • the present invention has for its object to provide a connection option for an electrical device to a connection means of an electrical system, which avoids complex reconstruction measures, has the smallest possible space and allows a simple and secure connection of the electrical device.
  • connection adapter in question has at least one group of encompassing elements, which are disc-shaped and mutually are pivotably connected at least in a closing direction by means of a hinge about a hinge axis arranged perpendicular to the encompassing elements, wherein the encompassing elements each have a recess for partially encompassing the connection means, wherein the recesses of the encompassing elements of a group of encompassing elements together define a receiving region for at least partially receiving the connection means, wherein at least one encompassing element of a group of encompassing elements has a closure opening which tapers in the closing direction and which has an overlap region for inserting a closure element with a closure opening of another encompassing element of the group of encompassing elements, and wherein actuation and / or insertion of the closure element in the overlap region causes movement of the encompassing elements about the hinge axis in the closing direction.

  • connection adapter which uses this space and allows connecting the electrical device to the connection means.
  • the connection adapter comprises at least one group of disk-shaped encompassing elements, which are connected to one another with at least one hinge.
  • the encompassing elements are movable about a hinge axis formed by a hinge and arranged perpendicular to the Umgreifimplantationn, wherein at least one movement should be made possible in a closing direction.
  • Each encompassing element has a recess which can partially embrace a male connection means.
  • the recesses of the encompassing elements of a group of encompassing elements delimit a receiving area that leads to the at least partially receiving the connection means is formed.
  • a "partial reception of the connection means" will be expected in particular when the connection means is large. Thus, for example, in the case of an M12 screw, only part of the screw head should be received in the receiving area as connection means.
  • At least one of the encompassing elements of a group of encompassing elements has a specially designed closure opening.
  • this specially designed closure opening tapers in the closing direction and forms an overlap region with a closure opening of another encompassing element of the group of encompassing elements.
  • the closure opening of the other encompassing element can likewise be designed to be tapered or non-tapered. It is important that through the overlap region an opening is formed by the encompassing elements involved, through which a closure element can be guided.
  • connection adapter can be safely installed on a connection means and can be easily constructed at the same time. If several groups of encompassing elements are used, the overlapping area can extend through the closure openings of all encompassing elements involved in the closing movement.

  • Disc-shaped means that the dimensions of the encompassing elements are significantly larger in at least one direction than in the direction of the thickness.
  • the term should not be understood as limiting the shaping of the encompassing elements to a very flat cylinder.
  • connection adapter For the operation of the connection adapter according to the invention, it is in principle irrelevant how many groups of Umgreifimplantationn has the connection adapter.
  • the connection adapter must have at least one group of encompassing elements, so that this forms a lower limit. Too many groups are impractical because such a terminal adapter would be impractically large in size. If, for example, the connection adapter had 100 groups of encompassing elements, then the connection adapter would reach a barely manageable thickness. In practice, an upper limit is expected to be 10 groups, and this will usually depend on the thickness of the individual encompassing elements.
  • the thickness of the disk-shaped encompassing elements will essentially be based on the material used.
  • the Umgreifieri should be thick enough that they do not deform when mounting the connection adapter on the connection means. This means that the Umgreifamine must be capable of the material used and the thickness used to absorb the forces occurring during assembly and during use of the connection adapter largely without deformation. At the same time the Umgreifimplantation should be thin enough so that they can still be considered as "disc-shaped" within the meaning of the present invention.

  • the Umgreifetti are made of a conductive material or that at least the inside of the recess or parts thereof is / are electrically conductive.
  • the conditions are particularly favorable if the encompassing elements consist of the same material as the connection means.
  • connection adapter Since the connection adapter will usually be manufactured for known connection scenarios, the expected material of the connection means is usually known and thus easy to realize these conditions in practice. A similar material between connection means and encompassing elements is also recommended for the prevention of galvanic corrosion, especially if the electrical system, for example, can be found in the outdoor area of a road distributor and a high humidity is expected.
  • the encompassing elements are preferably produced in one piece.
  • connection means of the electrical system can be formed in various ways. In principle, any electrically conductive body that is part of the electrical system and is connected to a conductor of a power supply network would be suitable as a connection means.
  • prism-shaped connection means are particularly well suited, since a large contact surface between connection means and connection adapter can be realized there, which in turn favors the frictional connection between connection means and connection adapter.
  • this prism-shaped connection means may have smooth surfaces or be structured.
  • the prism-shaped connection means can in principle even be formed by a threaded portion.

Therefore, after the installation of the connection adapter on the connection means, a part of the narrow edge of the encompassing elements will always be in contact with the connection means.
  • the limiting edge of the encompassing elements can be designed in various ways.
  • the edge could be smooth.
  • the edge is profiled. This profiling can consist of both a relatively fine structuring and a coarse structure. Fine structuring may be formed, for example, by relatively arbitrarily shaped lines in the surface of the edge, thereby creating a roughened surface.
  • the fine structuring can be formed by teeth which, in the mounted state of the connection adapter, are in direct contact with the connection means on the connection means.
  • Such a fine structuring makes it possible to improve the frictional connection arising between connection means and connection adapter.
  • the fine structure can contribute to the penetration of a corrosion layer possibly present on the connection means.
  • a coarse structure can be formed by an adaptation of the edge of the encompassing elements bounding the recess to the connection means.
  • connection adapter without such a coarse structure in a relatively arbitrary orientation about an axis parallel to the hinge axis can be arranged.
  • the contact area between connection adapter and connection means could not be sufficiently large, so that the connection between connection adapter and connection means would not be sufficiently loadable. Therefore, in a preferred development, a coarse structure is present on the edge bounding the recess.
  • the edge bounding the recess can be modeled on the course of the male connection means to be received.
  • the edge delimiting the recess can be profiled by projections and / or recesses. This results in roughly textured teeth that would at least partially be in contact with a received connection means.

  • a hinge may be formed in this embodiment by a hinge pin which is guided by hinge openings in the Umgreifimplantation.
  • the hinge pin can also be used as a connection point for a connecting cable of the electrical device.
  • a corresponding connection option would have to be created on the hinge pin. It would be conceivable, for example, that at one end of the hinge pin an eyelet is formed on which the connecting cable can be attached. It would also be conceivable that a thread is formed at one end of the hinge pin to which a cable lug of the connecting cable can be attached. A specialist will have different options recognize how such a pin can be used as a connection point for a connection cable of an electrical device.
  • the closure opening of a Umgreifelements can be formed in various ways. Thus, it is irrelevant, for example in many embodiments, whether the taper in the closing direction is symmetrical to an axis arranged parallel to the closing direction. Furthermore, the shape of the closure opening is largely irrelevant, as long as the mold used is adapted to bring about a sufficient closing movement upon actuation and / or insertion of the closure element in the overlap region. In this sense, for example, a closure opening with a simple circular cross-section may not be suitable, since a sufficient closing movement is not expected. In particularly preferred embodiments, the closure opening is drop-shaped or formed by two differently sized eccentrically arranged openings or a slot with a subsequent bore.
  • a connection region can be formed, which can be designed to connect a connection cable of the electrical device.
