Definitions

  • connection device of the type mentioned at the beginning.
  • This is characterized in that an electrically conductive connecting piece is interposed between the cable connection means and the pick-off element, that a connection housing - or housing for short - has at least one longitudinally extended front end and one radially around the front end End of the tapping element located area encloses, and that the cable connection means and the connector are arranged in the radially located area.
  • a basic idea of the invention is that the pick-off element is arranged next to the cable connection means—seen in the axial direction of the pick-off element.
  • the basic idea thus overcomes the previous teaching, namely that a tapping element and the connection means would have to be arranged one behind the other in the axial direction.
  • the use of the connection device according to the invention is particularly advantageous in the voltage ranges from 230 V to 12 kV or 230 V to 24 kV, since in these voltage ranges the switchgear often offers little space for the attachment of connection devices.
  • the pick-off element and the cable connection means are arranged in a housing which is preferably made of an electrically insulating material.
  • the housing also offers the advantage of touch protection.
  • connection device according to the invention to connect to a neutral conductor or to a neutral conductor instead of to a current-carrying conductor.
  • connection device according to the invention offers the possibility of arranging all standardized cable connection means in the housing, for example screw terminals, spring terminals, compression cable connectors or soldering lugs.
  • the radially adjacent arrangement of tapping element and cable connection means has a minimal axial space requirement and also has a particularly compact design compared to other products available on the market.
  • connection device both the pick-off element and the cable connection means can be accessed and operated independently of one another, even when installed. This opens up the possibility of assembling or disassembling the connection device according to the invention during the operation of a switchgear, ie to operate the pick-off element, independently of the operation of the cable connection means. Up until now, it was only possible to disassemble, for example the above-mentioned connecting crown, if the cable had first been removed from the cable connecting means and then the connecting means themselves.
  • a further advantageous embodiment of the connecting device results when the connecting piece has an electrical safety or temperature monitoring element.
  • the fuse element can be a fuse, for example.
  • Such fuses have hitherto been housed in the connection cable or in the device itself to be connected.
  • Powerline communication devices, measuring devices or machine tools such as drills, for example come into consideration as devices that are supplied with power using the connection device.
  • the connection device can also advantageously be used to connect a neutral conductor or a connection point for the ground of a circuit.
  • the connecting device is also characterized in that the securing element is encased in a shrink tube.
  • the shrink tubing can also be used as a display element.
  • An example of this is a through-wire as a temperature monitoring element, which is encased in a hose that shrinks at a predeterminable temperature. If the specified temperature is then exceeded, the stocking tube shrinks, indicating that the maximum temperature has been exceeded.
  • the standardized coloring of this heat-shrink tubing can be used to indicate different technical properties, such as the maximum desired temperature range, which can then be recognized at a glance.
  • a connecting dowel, a clamping element, a clamping disk or a plug-in element can be considered in particular as a pick-up element for the connection device according to the invention.
  • plug-in elements are also provided as pick-off elements.
  • Such plug-in elements are, for example, piggyback tongues, busbar clamps or clamping elements that represent passive components, ie have no moving parts or moving clamping parts for clamping at a connection point on the switchgear. Instead, these passive components are plugged into busbars or holders at points provided for this purpose and, if necessary, from there located clamps, notches or other fasteners fixed and held.
  • the cable connection means is a spring-type terminal, a crimp connector, a spring terminal, a screw terminal, a plug-in terminal or a snap-in connection.
  • These are all quick-connecting, detachable connecting elements, which are known to the person skilled in various configurations. In this way, the assembly times are reduced and it is also made possible in a particularly simple manner to disassemble the connecting device by first removing the connected cable. It is also advantageous for certain applications if, for example, a soldering lug or a compression cable connector is provided, with which the connecting cable can be attached with a connection to the soldering lug or to the compression cable connector. Then the advantages of a connection between the cable and cable connection means that cannot be easily detached are in the foreground.
  • a further embodiment variant of the connecting device provides that the radially located area is divided into at least two partial areas by an electrically insulating partition wall or separating layer between the pick-off element and the cable connection means.
  • the primary circuit e.g. a switchgear
  • the secondary circuit ie the circuit for the power consumer to be connected.
  • a holder for the securing element is thus created in a particularly simple manner, with a partial area for a pickup side of the pickup element and a partial area for a cable side of the cable connection means being separated at the same time.
  • the holding device has at least two hook-like holding elements which engage in the recesses in the housing, the hooks gripping behind the housing in the region of the recesses by means of a rotary movement and jamming on the holding device.
  • a central recess can be provided in the holding device, with a central recess then also being provided between the recesses in the housing.
  • a further tool for example a Torx screwdriver, can then be passed through this central recess, which fixes a connecting dowel in the desired position by screwing in a clamping element—in the simplest case a screw.
  • the advantage here is that a fitter can operate two tools, namely a holding tool with the holding device and a screwing tool, whereby the space requirement for both tools is no greater than the holding tool, since the screwing tool passes through a centrally located recess on the hand tool, through the recess the holding device and is guided through this recess and the central recess in the housing. If several holding devices are attached to the connection device according to the invention, there is the advantage that a fitter can select the optimal holding device for the installation, depending on the cramped installation situation.
  • connection device is characterized in that at least one recess in the housing is arranged in such a shape and at a point that a tool part of a tool can be passed through the at least one recess and the pick-off element or the cable connection means can be connected to the Tool part is operable.
  • the pick-off element and/or the connection means can then be operated in a particularly simple manner.
  • the housing to have at least one through-hole which is fitted at a point suitable for voltage testing. It is therefore also provided according to the invention, if necessary, to introduce through-holes in the housing at such locations in order to reach the desired locations inside the housing.
  • Such through-holes can also only be prepared in the housing cover, for example by means of a perforation, with a housing cover area surrounded by a perforation simply being broken out—by hand or with a tool—if required, so that the desired through-hole is created.
  • connection device is designed in such a way that the housing is an electrically insulating housing and is designed to be open or transparent at least in places so that it cannot be touched. This ensures that certain points inside the housing are visible, for example the fuse element, correct plug-in length of the cable or identification of the fuse type, while at the same time protection against unintentional touching of this point is provided.
  • the connection housing can therefore be colored throughout and only transparent in places or be made entirely of transparent base material, with those areas that are not intended to be transparent being provided with a rough surface or being otherwise non-transparent.
  • connection device is achieved when a connection space is formed in the connection housing in such a way that a crimp butt connector can be latched or clamped after it has been crimped in the connection space on snap-in connection or clamp connection elements arranged there.
  • a crimp butt connector For a crimp connection, two conductor ends are first electrically conductively connected to one another by crimping a crimp butt connector - often with appropriate pliers. This process usually occurs outside of the junction box. After the crimp connection has been made, the crimp butt connector is arranged in the connection space at the point provided for this purpose and is either latched or clamped there, so that the crimp butt connector is advantageously fixed in the connection housing. 5
  • FIG. 1 shows a plan view of a first connecting device
  • FIG. 9 shows a perspective view of a fifth connection device
  • FIG. 10 shows a sectional view through the fifth connection device
  • FIG. 11 shows a three-dimensional view of a sixth connection device.
  • FIG. 1 shows a top view of a first connection device 10 with a connection housing 12, which has a housing cover 13, in which a first 14 and a second holding device 16 are incorporated.
  • the holding devices 14, 16 each have a number of six recesses, which are arranged around the one central recess 17.
  • the six recesses are each approximately eight-shaped, into which a small parts assembly tool engages with corresponding hook elements and is clamped by a rotary movement of the small parts assembly tool on the connection housing 12 in the region of one of the holding devices 14, 16.
  • the first connection device 10 can be handled particularly easily and placed at the point at which it is to be mounted, for example.
  • connection housing 12 there is then the possibility through the central recess—either one or the other holding device 14, 16—to introduce and use a further tool in the connection housing 12 .
  • the central recess of the second holding device 16 is intended for a tool to be passed through it in order to operate a pick-off element—that is, to attach or detach it, viz in the example shown to clamp or unclamp a connection element on a screw head of a switchgear.
  • This connection element is shown in one of the following figures.
  • Other connection elements can be, for example, hexagonal screws, nuts, stud bolts, hexagon socket screws or connecting plates.
  • the first connection device 10 in the exemplary embodiment shown therefore only extends by the thickness of the housing cover 13 beyond a front end of the screw head—seen in the axial direction of the screw.
  • the screw head is listed here as an example of a live connection element in a low-voltage switchgear.
  • a through hole 42 is arranged in the housing cover 13 next to the second holding device 16 in a circular cover area 44 of the housing cover 13, which cover area 44 is arranged at the point at which the first holding device 14 is located in the first connecting device 10.
  • the through hole 42 is arranged within the cover area 44 and has such a diameter that - in the selected example - a torx drive 46 of a second pick-off element with a corresponding tool - here for example a screwdriver with a torx drive - the second pick-off element by means of the torx Drive 46 can be operated.
  • this means that the Torx drive 46 is inserted in the head of a metric screw and this can then be moved either clockwise or counterclockwise using the tool.
  • Fig. 5 shows a side view of the second connecting device 40, in which the second pick-off element 48 in particular is visible in the figure, namely in the selected example a connecting or expansion dowel, which increases its outer diameter by screwing the metric screw into the expansion dowel and is thus jammed, for example, in a borehole of appropriate size on the borehole wall and is fixed in this way in the borehole.
  • unscrewing the metric screw from the expansion anchor causes a reduction in the outer diameter, so that the clamped connection between the borehole wall and the expansion anchor loosens again.
  • the figure does not show the housing cover 13 but only its expansion dowel 48 in order to provide a view of the other components of the second connection device 40 .
  • the expansible dowel 48 - in addition to its holding function - is provided for establishing an electrical connection with the box terminal 52 or ultimately the conductor 54 .
  • the spring clip 60 is fixed in a stationary manner on the housing base 18 .
  • the following is interposed as an electrically conductive connecting piece between the spring clip 60 and the second pick-off element 48:
  • a first conductor piece 62 is connected at one end to the spring clip 60, welded in the selected example, and at its other end to a first safety shoe 64
  • An electrical fuse element 66 -- a fuse in the example shown -- is held between the first 64 and a second fuse shoe 68 .
  • a first end of a second conductor section 70 is in turn attached to the second securing shoe 68, which is connected at a second end to the second pick-off element 48—the expansion dowel.
  • the connection point between the second pick-off element 48 and the second conductor piece 70 is not shown in the figure because—as already mentioned above—the housing cover 13 with the second pick-off element 48 located therein is not shown in the figure.
  • FIG. 10 shows a sectional view through the fifth connecting device 84, with the crimp butt connector 86 being omitted from the view for a better overview.
