Definitions

  • plug-in terminal is from US-PS 3945711 known.
  • the end of the cable is between one rigid metallic component and a spring set. This spring is opened when the cable is inserted. requirement is that the cable is a that deals with a single wire that is sufficient is firm to deflect the spring.
  • the invention has for its object to a plug-in terminal create that also for connecting electrical cables is suitable in which the cables are in the form of strands.
  • the invention proposes a plug-in terminal with the features of claim 1. Training the invention are the subject of the dependent claims, their wording as well as the wording of the summary is made by reference to the content of the description.
  • the plug-in terminal proposed by the invention contains practically two brackets for the free end of the strand, namely a bracket by the actuator must be opened, and a second bracket that with so low force can be opened that this can also be Inserting a strand is possible.
  • This second bracket needs the end of the wire only during the connection process to hold, so not to take up any greater forces. It is therefore possible to design the bracket so that it can be opened almost with zero force.
  • the third holding element forms together with the first or with the second holding element a separate holder for the Strand.
  • This bracket is also effective when using of the actuating element, the main bracket for insertion another cable is opened.
  • the third holding element is designed such that it by inserting the cable with very little force can be opened.
  • the third Holding element when pulling the pinched cable one developed greater locking force than this for insertion was required.
  • the third Holding element have spring properties, so even Generate spring loading.
  • the third Retaining element is a tongue spring clamped on one side.
  • This can, for example, be arranged such that it is cut open when inserting the cable, i.e. by the cable is deflected to the side.
  • the tongue spring can be used for this slanted in the direction of insertion from front to back opposite to the direction of insertion.
  • the clamped End of the tongue spring in the direction of insertion before the free end is arranged and the fixing of the cable by an edge in the area of the free end.
  • the tongue spring at Pulling on the cable cannot avoid it. This allows achieve a higher force than it is for pushing in is required.
  • tongue spring Another possibility of arranging the tongue spring can consist of the clamped end in the direction of insertion is located behind the free end so that the Determined by increasing frictional engagement over the length of the cable.
  • the invention proposes that Actuator for opening the main brackets at the same time all recordings can be formed.
  • the mechanic takes the clamp in one hand, opens it with, for example the thumb, and then pokes the ends of the ones to be connected Insert the cables one after the other into the individual recordings. There they are first from the second automatic bracket set with little force until all cables are plugged in are. Then the fitter lets go of the actuator, and now all cables are through the respective main bracket held with great strength.
  • the recordings are arranged side by side and all cables from one Direction in the recordings can be inserted. This makes handling the plug-in terminal easier.
  • the actuating element formed by a pivotable cover of the housing becomes.
  • the first holding element is fixed to the housing, so that only the second Bracket element pivoted through the actuator are needed.
  • the first holding element a metallic all through the housing Recordings is common disc.
  • each recording has its own second holding element. This is particularly so then of great advantage if the cables to be connected do not have the same diameter.
  • the second holding element like the third, Have spring properties, so designed itself as a spring his.
  • the housing with insertion aids to facilitate threading the cable is provided, for example with a kind of funnel, which leads the front end of the cable into the receptacle.
  • FIG. 1 shows a plug-in terminal in perspective, the one Has housing 1 with a cover 2.
  • the housing 1 contains on its one flat long side 3 four openings 4, through which each plugged a cable into the plug-in terminal can be.
  • the lid 2 is designed so that it in Figure 1 upper side and the two end faces of the housing covers. It can be placed on the front upper edge of the Housing 1 extending axis can be pivoted.
  • FIG. 2 shows the housing 1 from a different perspective removed cover.
  • the housing 1 is completely out Made of plastic.
  • the wall having the openings 4 of the housing 1 is made relatively thick in order to ensure that the metallic to be inserted into the housing Parts have a clear distance from the outside.
  • a wall 6 In the housing is in front of the rear wall 5 at a distance from this a wall 6 is formed, on which four holding elements 7 are formed are.
  • the holding elements 7 are made of a tongue spring Plastic trained. Your clamped end is from the Openings 4 removed on the rear wall 6 while you free end 8 is directed forward. The holding elements 7 can therefore dodge upwards and downwards. For every Such a holding element 7 is present in opening 4. An in the opening 4 inserted cable slides on the edge 8 over and along the tongue feather.
  • FIG 3 now shows a on a slightly enlarged scale Cross section through a plug-in terminal shown in Figure 2 Embodiment with the already mentioned metallic Insert part.
  • the openings 4 for inserting the cables are oriented to the right in Fig. 3.
  • At the opening in the front wall 3 is followed by a first funnel 8, which then into one second slightly flatter funnel 9 passes.
  • the free end 8 of the holding element 7 extends into this second funnel 9 inside.
  • the receptacle for the end of the cable is between the metallic plate 10 and the tongue spring formed by the holding element 7 is formed.
  • the wall 6 forms one internal limitation for the inclusion in the axial direction.
  • the Space between the rear wall 5 and the distance from this extending wall 6 serves to close the metallic plate 10 hold.
  • the holding element 7 designed as a tongue spring has on its long side facing the metallic plate 10 a total of three projections that are inclined in the direction of insertion running fingers are formed. They educate their free ends edges. These protrusions serve one to effect improved retention of the cable without the Pulling out the cable, if desired, prevented becomes.
  • knobs, grooves or the like can also cause an increase in the holding force.
  • the metallic plate 10 shown in more detail in Figure 5 is a first holding element for the receptacle, this plate 10 passes through the entire housing and is common to all recordings.
  • the plate 10 is flat and at its left end in Figure 3, i.e. the rear end, bent upwards at right angles in FIG. 3.
  • On the short leg 11 thus formed is a further metal element 12 attached, for example riveted or welded on.
  • This metallic element 12 forms at its opposite end the second holding element for the cable.
  • the metallic element 12 is curved and because of this and because of its length exhibits feather shadows on. It contains 13 in the area of its free end a closed opening 16 through which the cable passes can be inserted.
  • FIG. 5 shows the metallic Insert part for the embodiment according to FIG.
  • the plate 10 has the in the area Openings 4 facing the front end 14 each narrower projection 15 by the already mentioned Opening 16 of the holding element 12 passes through.
  • the opening 16 is approximately rectangular.
  • the spring force of the Holding element 12 is selected so that one edge of the Opening 16 on the lower side of the projection 15 in FIG. 5 abuts, in Figure 3 on the upper side of the projection 15th If you press in Figure 5 on the upper curved edge 17 of the Holding element 12, the front end pivots in Figure 5 down and in Figure 3 up so that the Opening 16 to lie behind the opening 4 of the housing 1 is coming. Then a cable can pass through the opening 16 between the metallic plate 10 and the holding element 7 inserted until its end is against the wall 6. While this insertion movement is the cable from the side acted upon by the holding element 7, the loading effective along the entire length of the inserted end is. This creates an increasing force that is sufficient can hold the cable so that Installation of the other cables does not slip out again.
  • the Cover 2 of the housing With its inside on the curved area 17 of the holding element 12 and this presses panned. Having this way the cables in all The installer leaves the cover 2 Come on.
  • the holding elements 12 try to relax, which simultaneously pivots the lid 2 and that front end 13 of the holding element 12 perpendicular to the longitudinal axis the recording and thus also moves perpendicular to the cable, until this between the plate 10 serving as a holding element and the edge of the opening 16 fixed and held becomes.
  • the holding element 7 acts in this jammed state still in some way with.
  • FIG 4 shows a modified embodiment in which in the Housing 1, see Figure 2, the tongue spring 7 as the third Holding element is no longer present. Instead, it's on metallic plate 10 another tongue spring 18 made of metal attached, which is also a continuation of the second holding element 12 can act.
  • This tongue spring 18th is also on the rear leg 11 of the plate 10 attached. It initially protrudes parallel to the plate front and is angled there at an acute angle 19, so that part 20 is seen from the front again in the insertion direction runs backwards. At the end, an edge 21 is formed rests on the cable when the cable is inserted.
  • the Tongue spring can be very much when inserting the cable slightly deform to the side. When trying to get the cable out to pull, the edge 23 wedges in the strand, since at a movement of the edge 21 forward, i.e. in Figure 4 right, no spring giving is possible. The feather will stressed in its section 20 and can therefore do not dodge.
  • the third holding element 18 only serves the cable 2 pushed in while the cover is pressed hold temporarily until all cables are inserted and the fitter releases the cover 2.
