Definitions

  • the invention relates to a contact apparatus for contacting electrical cable conductors with busbars, which essentially consists of an open-ended insulating housing and at least one broad-area connection lug arranged therein, the latter having a pair of spring-loaded contact fingers at one end and with a clamping lug contacting bracket of the cable conductor is equipped at its other end.
  • Such a contact apparatus is the European one.
  • Patent 0 012 455 can be seen and is already used in the corresponding systems.
  • a separate holding element is used, which causes the connection lug to be held in its housing in a manner which is at most slightly displaceable.
  • the handling of this holding element is simple, but it adjusts is a separate part, which can easily fall down during assembly and can also be lost. Otherwise, the risk that this holding element can slide out due to vibrations, for example during transport, cannot be completely ruled out.
  • the object of the present invention is to further simplify the assembly of the contact apparatus and to avoid the risk of improper mounting of the terminal lug inside its insulating material housing. It is desirable, moreover, to provide a contact apparatus may be suspended which is also higher in case of need current loads without the degree of connection lugs materiality - Lich to increase because the Ausbiegles the to-install on the busbars contact fingers couples then becomes critical.
  • a flap resiliently extending transversely to the insertion direction of the connecting lug is formed, which is provided at its freely resilient end region with at least one latching lug, which in turn behind an edge of a recess in the connecting lug - preventing its return - and furthermore that the connecting lug has on at least one of its narrow sides a projection which, in the inserted and latched position of the connecting lug in the insulating housing, abuts a housing projection projecting into the interior of the housing and thus prevents an insertion movement of the terminal lug beyond the latching position.
  • the freely resilient end of the resilient tab can also be at least slightly tapered compared to its remaining thickness and the rest of the catch can be located before this tapering begins. This tapering of the outermost free end of the tab offers easy releasability of the terminal lug, namely by means of a simple knife or screwdriver, that is to say by means of a simple or even provisional tool.
  • insulating material housing of the contact apparatus with regard to the most important inner contours as an approximately tubular part with a longitudinal wall part that divides the pipe cross section in the area of the insertion end for the connecting lug, of which two cross-sectionally forked, resiliently bendable tabs with theirs free ends arranged locking lugs go out; in this case, each of the tabs serves to hold one of two connecting lugs opposite one another in mirror image with their broad sides.
  • two connection lugs can be arranged within one and the same insulating material housing, whereby - at least when the cable conductors are connected in parallel - the current carrying capacity of the contact apparatus is practically doubled.
  • the proposal is to provide ribs directed from the insulating material housing into the interior of the housing or instead to emboss grooves in the walls of the insulating material housing which adjoin the lateral edges of the connecting lugs to be accommodated.
  • the housing protrusion can be provided at the ends of the respective rib or said groove (always seen in the insertion direction) against which the associated protrusion of the connecting lug, which prevents its further insertion, strikes. If such a housing projection is combined with the adjacent rib in terms of material, there is a particularly favorable value with regard to the load-bearing capacity of the housing projection. The risk of a housing projection of this type breaking off is thus also present in one Impact load not intended in itself practically excluded.
  • an insulating housing for a contact apparatus of the type in question design of an insulating housing for a contact apparatus of the type in question can be seen in giving the said housing a box-like shape, of which a single or multi-channel connector for receiving one or more terminal lugs lying one by one with the narrow sides or one or more terminal lugs arranged in pairs next to one another.
  • a resilient tab formed on a channel wall or a transverse wall with at least one latching lug can be arranged on the freely resilient end region within the or each channel of the single-channel or multi-channel connector, whereby it is provided that insert a connection lug within each channel and lock it using the latch.
  • means for connection to adjacent insulating material housings of the same design can also be formed on the insulating material housing, in particular inclined projections, which allow a plug connection of mutually adjacent insulating material housings according to the known swallowtail principle.
  • Comparable means and designs can be found in the already mentioned European patent 0 012 455 and are therefore no longer new per se, not even for contact devices of the particular type in question here.
  • a particularly well-designed, but also very important training option for contact apparatuses according to the present invention can be seen in the proposed idea of designing the insulating housing for receiving one or more connecting lugs as a molded-on component of an insulating part, the latter being of greater dimensions than it is for receiving the provided connection lugs is required, and which serves other functions, namely in particular as a slide-in wall, as a frame wall for slide-in cabinets, as a device housing or the like.
  • these contact devices can also be directly attached to large-area insulating material parts, in the sense of being molded onto these insulating material parts.
  • the insulating device serving the contact apparatus regardless of whether it is a single-pole or multi-pole separate contact apparatus or a construction as mentioned last, on its end surrounding the contact finger pairs of the connecting lugs on opposite walls with slot-like walls to provide recesses in the same direction with the between the Contact finger pairs formed slots located, but at least slightly wider than these slots are formed, and allow a continuous straight course of busbars to be contacted with the terminal lugs.
  • This has the advantage that the contact point between the busbar and the terminal lug to be clipped thereon is largely surrounded by the housing in a protective manner.
  • connection lug 2 already equipped with a cable conductor 1 for a contact apparatus according to the present invention.
  • this terminal lug 2 has a pair of contact fingers 3 and 4 at its end pointing to the right in the illustration and, at its opposite end, a originally flat and jagged terminal lug 5, which is now clawed to the cable conductor 1, by means of a circular spring clip 6 are the contact fingers 3 and 4 pressed towards each other, the free ends of the spring clip 6 engaging on webs 7 and 8 which are bent out towards the viewer.
  • this connecting lug 2 additionally has two characteristic features, namely projections 9 and 10 on its narrow sides, and a right-angled opening 11 with a clearly uneven aspect ratio, the longitudinal course of this rectangular opening 11 being transverse to the longitudinal extension and also for Direction of insertion of the terminal lug 2 is located.
  • the projections 9 and 10 just mentioned are created by notching in the area of the contact fingers 3 and 4.
  • the bendability of the contact fingers 3 and 4 is improved or facilitated by a slit 12 and an elongated hole 13 in the connecting lug 2.
  • FIG 2 a portion of an insulating housing 14 is shown cut open, and that is equipped with the connection lug 2 shown separately in Fig. 1. It should also be noted that this connection lug 2 is plugged onto a busbar 15, the rectangular cross-section of which - hatched - can be seen . Furthermore, it can be seen from this illustration that the projections 9 and 10 on the terminal lug 2 abut housing projections 16 and 17 projecting into the interior of the insulating material housing 14, so that further insertion of the terminal lug 2 into the insulating material housing 14 is prevented.
  • connection lug 2 which can again be seen here, has thus already assumed and maintained its position as shown in FIG.
  • connection lug 32 can be seen in its not yet fully inserted position, the second tab 22 now bending with its latching cam 28.
  • the connecting cam 28 will engage in a rectangular opening 33 of the connecting lug 32 and thus fulfill the holding and locking function already described. It is worth mentioning that the connecting lug 32 can be inserted a little deeper into the insulating housing 1%, due to the somewhat longitudinally displaced position of the housing projection 23 and the locking cam 28.
  • connection lugs So much for the formation of the connection lugs as well as for their latching and fixing in position in the insulating material housings of contact devices:
  • the following explanations now relate to the design options of insulating material housings for contact devices of the type in question.
  • FIG. 4 illustrates in a longitudinal section an insulating material housing 34, which could roughly correspond to the one as indicated in FIGS. 2 and 3a to 3d. It has an essentially tubular shape, the insertion area for two connecting lugs pointing to the left in the illustration being in turn penetrated by a wall part 35. Tabs 36 and 37 extend from this wall part 35 and run in a fork-like manner to one another in the cross section shown. Each of these tabs 36 and 37 is provided with a locking cam 38 and 39, the meaning and function of which has already been explained in detail in connection with the individual representations of FIGS. It may also be worth mentioning that the tab 37 is longer than the other tab 36, and the locking cam 39 is also offset from the opposite locking cam 38.
  • protruding housing projections 40 and 41 are formed in the interior of the insulating housing 34, which serve as stops for the terminal lugs to be received.
  • FIG. 5 illustrates a top view of the insulating material housing 34.
  • FIG. 5 illustrates a top view of the insulating material housing 34.
  • the end of the insulating material housing 34 which points towards the right in the illustration has recesses 46 and 47 (see also FIG. 4) which serve for the passage of current busbars, or in other words: are necessary when one - As happened in the present case - the insulating housing 34 would like to protect around the ends of the terminal lugs to be contacted with the busbars to be accommodated.
  • FIG. 6 shows a section VI-VI, the course of which is indicated in FIG. 4. Recognizable here inside the wall part 35 with the tab 36 emanating therefrom, further the housing projection 40 and a further housing projection 48, the recess 47 and ribs 49 and 50 not previously mentioned for guiding and fixing the position of a connecting lug. Otherwise, the oblique projections 42 to 45, the meaning of which has already been explained, can also be seen in this sectional illustration.
  • FIG. 7 A section VII-VII, the course of which is indicated in FIG. 5, is illustrated in FIG. 7.
  • FIG. 8 illustrates a view of the insulating material housing 34 that is made in the opposite direction to that just mentioned, corresponding to a side view of the illustration in FIG. 5.
  • the fastening tabs 53 and 54 can be seen from their other side, and again the wall part 35 and the mutually bendable tabs 36 and 37.
  • FIG. 9 shows an opposite view (view A according to arrow A in FIG. 6), which requires no further explanation, except for the reference to the numbered recesses 46 and 47.
  • An insulating material housing such as the one just described (34) can accommodate two connection lugs according to FIG. 1, and, as already said, in the manner in which this can be seen from FIGS. 2 and 3a to 3d.
  • FIGS. 10 to 12 A differently designed insulating material housing 55 is shown in FIGS. 10 to 12.
  • this first has a box-shaped area 56, from which a multi-channel connecting piece 57 now emanates.
  • This multi-channel connecting piece 57 contains three channels 58 to 60 which are closed off on the side, which in turn can be seen from FIG. 10 and the sectional view in FIG. 11. It is essential here that each of the channels 58 to 60 has a raised wall 61 from which each starts a tab 62 (see Fig. 11). This particular area within each of the channels 58 through 60 is shown again on an enlarged scale in FIG. 13.
  • this tab 62 also corresponds in terms of its design and position to the pools as have been shown in the exemplary embodiments explained above, and it also has the same task: namely to latch a connecting lug (not indicated in these representations) and in it Fix location.
  • ribs (64) and housing projections (65) also participate.
  • Introduction and fixation of terminal lugs which can practically correspond to those shown in FIG. 1, require no further explanation. All that is said is that instead of a paired arrangement of connection lugs, only one connection lug can be arranged in this insulating material housing 55 in each of the channels 58 to 60 mentioned.
  • this insulating material housing 55 is also provided with fastening means 66 and 67 in the form of molded ears and threaded bushings contained therein.
  • fastening means 66 and 67 in the form of molded ears and threaded bushings contained therein.
  • the paired arrangement of connecting lugs can also be realized if the wall parts and flaps (62) are provided in pairs.
  • FIGS. 14, 15, 16 and 17 illustrate an idiosyncratic modification with regard to the design of insulating material housings of contact devices of the type in question.
  • FIG. 14 shows a back wall, broken out in the middle, of an insert for a switchgear cabinet or the like, with the insulating material housing for contact devices also being molded on are.
  • the insulating material housings for the individual contact devices are therefore ultimately a material component of the slide-in rear wall, designated by the way with the number 68. It can be seen that three channel-like housing areas 69, 70 and 71 are integrally formed on the side pointing to the right in FIG. 14, and also further channel-like housing areas 72, 73 and 74.
  • the sectional views in FIGS. 15 and 16, the section of which can be seen from FIG. 14, illustrate the design of the channel-like housing areas 69, 70 and 71, the sectional view in FIG. 17, however, shows a section through the channel-like housing area 72 on the underside of the insert rear wall 68.
  • the last-mentioned FIG. 17 is shown on an enlarged scale compared to the representations according to FIGS.
  • the housing areas 85 and 86 serving the contact apparatus can be seen here, which, to say it again, are part of the insert rear walls (83 and 84) made of insulating material.
