Definitions

  • the present invention relates to an electrical plug-in component according to the preamble of claim 1 and a component set according to that of claim 6.
  • Such cubic devices be they bases, for example for plugging on industrial relays, or plug-on devices, such as the aforementioned industrial relays, are known and are often used in industrial controls, switchgear, etc., together with other electrical units, often with a large number of such units designed as bases Devices, arranged in rows, is used.
  • the present invention sets itself the task, starting from the above-mentioned known plug-in components, to create plug-in components which make it possible to use them Make optimal use of installation areas.
  • the plug-in component according to the invention is distinguished by the wording of the characterizing part of claim 1.
  • the present invention is based on the insight that, in the case of components of this type designed as plug-in bases, the volume spanned by the base component is in no way used for electrical engineering purposes and is also in no way necessary from a mechanical stability standpoint.
  • the device is designed according to the wording of claim 3 there is a highly flexible wiring option, for example, when the drive energy for a part to be plugged onto the socket can be routed via the pair of electrical contacts, which are connected through a bridging plug during operation or resiliently adjoin one another and which, for example, during service or inspection work, in which briefly the corresponding plug-in base with the part arranged on it is to be put out of operation.
  • the present invention is based on the knowledge that the object of the invention is achieved in the case of plug-in components of the abovementioned type which are conventionally designed as plug-in bases, in each case only as many, usually screwable, cable connections as there are sockets provided on the circular socket arrangement.
  • the electrical connection between the cable connections and the mentioned sockets is usually hard-wired in the socket.
  • the present invention further assumes that the space occupied by the conventional plug-in base is not used for the intended purpose.
  • the solution is found in aligning the cable connections to one another in the direction mentioned and in doing so displacing at least one of the locking screws with respect to the cable connection assigned to them to the rear or laterally and engaging with an extension from the locking screw in the assigned connection.
  • Fig. 1 shows a base, for example for industrial relays. Only the elements necessary to describe the first measure according to the invention are shown.
  • the structure of the plug-in base 1 is otherwise the same as the widespread "industrial relay" base, which is frequently used, for example, in control cabinets.
  • Known such plug-in bases comprise, as shown in dashed lines, a substantially cuboid housing body 3a, made of plastic, preferably as a molded component, on one side of which, in a circular arrangement 5, sockets 7 are provided for electrical contacting of plugged-on electrical components with correspondingly arranged electrical contact pins.
  • the socket circuit arrangement 5 is also known in its design and is therefore only shown schematically. It has a positioning and holding opening 9 in its center, for attached components. Circular plug-in arrangements of this type are known as 8-pin under the standard IEC 67-1-5a, c, d, 11-pin under IEC 67-1-18a.
  • the previously usual plug-in socket 3a are much wider than would be necessary for a given diameter ⁇ 5 of the socket circuit arrangement 5.
  • conventional base devices are 38 mm wide, with an outside diameter of the said circular arrangement of less than 25 mm. If two or a plurality of such base devices 1 are mounted laterally next to one another, this results in a packing density in which practically a third of the width is unused.
  • the width dimension B of the component according to the invention or its cuboid housing 3 is only determined by the outer diameter ⁇ 5 of the circular arrangement 5, if necessary taking into account the necessary leakage current and air gaps between bushings or Pinning neighboring arrangements.
  • a further component now designed as a plug-in, shown, in a known form (dashed) and according to the invention (extended).
  • the component according to the invention in turn comprises a cuboid housing 11, preferably made of plastic, with the width dimension B corresponding to the diameter ⁇ 13 of the circular plug 13 provided here with pins 15.
  • a component can contain, for example, a power relay arrangement in its housing 11.
  • a longitudinally continuous channel or shaft 19 is advantageously provided, preferably centrally and on the side of the housing 3 facing away from the circular socket arrangement 5.
  • cables 21 can be passed from one side of the plug base 1 to the other side without the lateral joining of the plug bases 1 being hindered or, unnecessarily wasted space due to the cabling being required anyway. This means that no additional cable routing is required.
  • the two measures described in each case with reference to FIGS. 1 and 3 can preferably be optimally combined to enable installation of such devices in a space-optimized manner.
  • Fig. 4 are two additional, each to solve the The object on which the invention is based is advantageously illustrated in combination with measures which are combined, these two measures, each individually or jointly, being combined with those described hitherto.
  • the socket 1 in turn has a circular arrangement 5 of sockets 7, conventionally their eleven or eight according to the standards specified above. Furthermore, the cuboid plastic housing 3, 3a is provided with cable connections 25. As can be readily seen, in the eleven sockets 7 provided here, twelve cable connections 25 are provided for the cabling of the plug base 1; in the case of eight sockets 7, there would be nine cable connections.
  • the second measure to be explained with reference to FIG. 4 is that, preferably on the same cuboid area on which the circular plug 5 is arranged, a holding recess 29 with electrical contacts 31 accessible therein is provided.
  • a holding recess 29 with electrical contacts 31 accessible therein is provided.
  • two pairs of opposing, resilient contact tabs 31 are provided. These contact tabs 31 are preferably electrically connected inside the base to the desired number of provided cable connections 25.
  • additional modules can be arranged in the holding recess 29, which are contacted by the tabs 31, such as interference suppression circuits, logic circuits, timing elements etc.
  • the holding recess can itself lie within the area covered by a device plugged onto the base 1 and / or next to it. If necessary, it is formed so deep that it can accommodate an additional module without the latter obstructing the device plugged onto the connector 5.
  • FIG. 5 shows a further embodiment variant of the base 1, in which the measures which were explained individually with reference to FIGS. 1, 3 and 4 are provided in combination:
  • FIG. 5 shows a preferred embodiment of the invention.
  • two further measures are provided, which can also preferably be used individually on a base 1 as part of a solution to the problem on which the invention is based.
  • the width dimension described with reference to FIG. 1 further has, in the case of the eleven sockets 7 shown here, twelve cable connections 25 and also the recess 29 with tabs 31 described with reference to FIG. 4.
  • the measures additionally provided here are a) a particularly space-saving arrangement of the cable connections 25 and b) the provision of adapter parts 35.
  • the side surfaces at which the connections 25 open out are essentially planar, and all connections 25 open out in the same plane.
  • the lateral connections 25 are also aligned with one another in the direction of the axes of the locking screws 27.
  • the locking screw 27a is displaced to the rear on at least one of the connections 25 and 25a one above the other and engages from behind with a protruding contacting part in the connection 25a.
  • FIG. 6 shows a variant of the protruding contact schematically shown in FIG. 5.
  • the screw 27a has an upper cylindrical, smooth section 37 which is in an equally smooth bore in the housing of the base 1.
  • the screw 27a protrudes through the cable connection 25a, is secured on its upper boundary surface by means of a collar 38 against axial movements.
  • the part 39 of the locking screw 27a projecting through the cable connection 25a has a thread 40, on which, provided with a corresponding threaded bushing 41, a contact arm 42 rides, which is moved up and down by rotating the screw 27a, as shown at P. 6, a "normal" locking screw 27 is shown in dashed lines, positioned with respect to the cable connection 27a in the same way as, according to FIG. 5, the screw 27 with respect to the connection 25.
  • connection socket 25a is also preferably designed here by means of a pluggable metal socket 43.
  • a stop surface 44 preferably formed on the arm 42 as part of the threaded bushing 41, ensures that a properly inserted cable end, possibly with strands, does not impair the function of the locking screw 27a or that the screw thread does not affect the cable end damaged.
  • adapter parts 35 are shown. Often when installing the plug-in base described, e.g. Conventionally wide replaced by space-saving according to the invention or, generally, mixed these two bases used in a predetermined building grid. In order to ensure that the base can still be supported and positioned laterally in the given grid, the adapter parts 35 are provided, preferably dimensioned according to half the width difference of the conventional base and the base according to the invention.
  • the adapter parts are preferably made of plastic, can be plugged onto conventional holding rails (not shown) for the base 1 or, for example, can be attached to corresponding side surfaces of the base 1 according to the invention. This achieves the greatest possible versatility for plug-in bases dimensioned according to the invention. Cable guides can again be provided in these adapter parts, as shown in dashed lines at 46, and / or these adapter parts 35 can be provided for accommodating further devices 48, such as for filters, timing elements, etc.
