Definitions

  • the invention relates to a plug insert element for flat cords for receiving in a connector housing, in particular for connecting to flat cords of low-voltage technology, consisting of an insulating part in which receiving guides for the ends of the single cores of the flat cords, which are closed on one side in series, are formed, with a contact tongue in each receiving guide submitted, which can be pushed through the insulation of the single wires and creates an electrical connection with the stranded wire of the assigned single wire.
  • a connector which has an insulating block area in which receiving guides for the single wires of a flat cord are introduced. From one side of the block area, clamps are inserted into the area of the receptacle guides, which contact the strands of the respective single wire with molded tips. On the back of these clamps facing away from the veins comes the Plug connection a KunststoffelEment lie so that the connection between the contact element and the single wires is made via the conductive terminal.
  • Such plugs are usually used in low-voltage technology, e.g.
  • the functionality of the plug is dependent on reliable contact making, which means that no large contact resistances may occur in the area of contacting to ensure proper contact.
  • Another requirement for these connectors is that they are relatively small and should ensure that the flat cords are held reliably.
  • the contact points are relatively small, but a material must be used for the terminals that has an extremely good conductivity, which can be achieved by gold-plated terminals.
  • the disadvantage here is that the connector is relatively expensive to manufacture.
  • the requirements of good contact could also be met in the known design in that the block area as a whole is made larger, so that larger contact points can be created, which can then ensure flawless contact using less conductive material.
  • the disadvantage to be accepted here is that such a plug would then have to be built relatively large.
  • the invention has for its object to provide a plug element for flat cords, in which more contact points can be created with the same size of the block area - while ensuring good contact - as is the case with the known design.
  • the insulating part is designed as a block with receiving guides arranged inside, that the contact tongues are formed as laterally angled areas of elongated contact springs and that the contact springs are arranged diametrically opposite on two mutually parallel outer sides of the block so that the contact tongues alternately extend from the opposite sides of the block into the receiving guides.
  • the spacing of the contact springs i.e. with a constant pitch for these contact springs and with constant dimensions of the insulating part, twice as many individual wires are contacted than is the case with the known design.
  • a material that is not as good as gold as a material for the clamps e.g. Nickel silver can be used, which makes the manufacture considerably cheaper than gold-plated clamps.
  • the broad sides of the block area are used as the two opposite sides, since the block area is usually cuboid and more space is available on the broad sides for the arrangement of the terminals.
  • the receiving channels are then formed in the middle of the insulating part in a row next to each other, so that the path for both terminals is the same from both sides to the single wires.
  • contact springs of identical design can be used for both sides.
  • the contact tongues are angled at right angles. Since the contact tongues on one side of the insulating part are rotationally symmetrical, i.e. are rotated by 180 ° to that of the other side, there is a simple structure.
  • the contact springs are held in receiving chambers on the opposite sides of the block area, since this fixes the position of the contact springs.
  • the contact springs can be arranged in such a way that they form a grid that meets the required DIN standards for plugs used in low-voltage technology.
  • Each receiving chamber is assigned a channel which corresponds to the angled area of the contact spring and which opens into a receiving channel of the block area.
  • the clamps designed as angled areas of the contact springs come to rest, and when the contact springs are inserted, the correspondingly angled areas are guided through these channels and are thus automatically brought into a position relative to the receiving channels in which it is ensured that they are the stranded wire touch the individual wires and therefore the corresponding seat of the contact springs is fixed by inserting the contact springs into the receiving chambers and inserting the angled areas into the receiving channel.
  • the plug insert element has a fork-shaped receiving area adjoining the block area, in the recesses of which the contacting curvatures of the contact springs come to rest.
  • this fork-shaped receiving area can likewise ensure that the contact springs are fixed and at the same time serves as the area in which the actual contact with the mating plug element then comes about.
  • the contact springs then extend from the block area to the end of the receiving area, so that relatively large contact areas are created.
  • the receiving chambers have plastic deformations on both sides of the seat of the angled region of the contact spring, the contact springs being provided with cutouts corresponding to the plastic deformations. This will make contact after insertion a fixation is achieved, with a suitable configuration of these plastic deformations, a simple pushing in of the contact springs can be sufficient to lock them on the block area of the insert element.
  • the contact springs can be provided with a threshold-shaped curvature that lies approximately in the transition area from the block area to the fork-shaped receiving area, which is followed by a contacting curvature in the direction of the receiving area.
  • the threshold-shaped curvature serves to absorb the forces that occur in the longitudinal direction of the contact springs when the plug insert element is inserted, so that no displacement of the position of the contact springs can occur.
  • the contact curvature in the receiving area ensures a certain spring pressure to support the contact establishment.
  • a cross-directional formation is provided, which can serve for the single wires to experience a cross-sectional narrowing in this area, whereby a protection against tensile stress on the flat cord can be achieved. This is done by pressing the plastic that is still between the wires and the recessed parts in the direction of the single wires, which happens after the insertion of the single wires into the receiving channels. This will then secure them against being pulled out.
  • the entire plug insert element can be made in one piece from plastic, e.g. as an injection molded part, which allows very cheap production. German silver can be used as the base material for the contact springs, which makes the production relatively cheap.
  • the plug insert element can be made into an angled plug formed plug-in wall can be embedded, but it can also be used in a plug-in wall designed as a straight plug.
  • this plug insert element thus represents a special form of the design of the root or crown side of a flat cord, which, depending on the intended use, can be inserted in different plug housings depending on the desired design.
  • FIG. 1 denotes the block area of a plug insert element according to the invention, which is designed as an insulating part and has a rectangular cross section.
  • Receiving guides 4 are arranged in the interior of the block area 2 and run at a constant distance from one another.
  • the single wires 3 of a flat cord are inserted into these receiving guides 4.
  • terminals in the form of contact tongues 5 extend into the area of the individual wires, cut through their insulation and make contact with the strands 7 of the individual wires 3.
  • the terminals 5 are angled laterally in front of the contact springs 12 and therefore laterally offset to these. They therefore open on the adjacent single wires 3 alternately from the opposite top and bottom sides 8 and 9 of the block area 2 into the receiving guides 4.
  • the terminals are provided with an angled contact surface 6, which can be selected to be relatively wide and is part of the associated contact spring 12 in the exemplary embodiment.
  • the contact springs 12 have a certain grid spacing S from one another which can meet the required DIN standards for such plugs. This arrangement of the alternate contacting with the aid of the terminals 5 enables a relatively large number of individual wires to be contacted, but there is still sufficient space for the contact areas, so that relatively large contact areas can be achieved. It is therefore not necessary to use material with very good electrical conductivity for the terminals.
  • the gold plating of the contact parts required in known, small-sized plugs can be omitted.
  • the terminals are automatically in a conical channel 1O their insertion into the block area 2 so that they inevitably open into the receiving channels 4, whereby a safe contact is always guaranteed.
  • the block area 2 of the plug insert element 1 is followed by a fork-shaped receiving area 13.
  • This receiving area 13 like the receiving chambers 22 of the block area 2, serves to receive a contact spring 12 which has an angled area which forms the clamp 5.
  • the terminal 5 has, for example, two tips 11, which achieve a better cut through the insulation and produce good contact with the wire 7 of the single wire 3 shown.
  • the contact spring 12 In front of and behind the terminal 5, the contact spring 12 is fixed in position after insertion by plastic deformations 14 which engage in recesses 16 in the contact spring 12. With a corresponding design of the plastic deformations 14, there is a clamping effect when the contact springs 12 are pressed in.
  • the contact spring 12 is provided with a threshold-shaped curvature 17, which is designed to correspond to a curvature of the plug insert element 1 at this transition area.
  • a contact arch 18 in the area of which the actual contact is made.
  • This curvature is designed so that a resilient contact pressure is created when the connector is brought together, which ensures reliable contacting over a large area.
  • FIG. 4 shows a plan view in the direction of arrow P on the plug insert element of FIG. 2, the arrangement of the contact springs 12 being recognizable.
  • the contacting curvature 18 is followed by the threshold-shaped curvature 17 from the receiving area 13 in the direction of the block area 2, which then merges into the part on which the terminal 5 is formed.
  • the shape 15 extending transversely to the direction of insertion can be seen, which is used to prevent the individual wires from being pulled out by using a tool to press the plastic remaining between the wire and the shape in the direction of the wires.
  • 5a to 6b show how the plug insert element can be used together with corresponding plug housings.
  • 5a shows a connector housing designed as an angled connector 19, in which the connector insert element 1 is received and fixed.
  • a flat cord 20 opens into the angled connector housing and is held there. The single wires are accommodated in the plug insert element, as can be seen from the previous explanations.
  • Fig. 5b shows a view in the direction of arrow Q of Fig. 5a this plug, the contacting curvatures 18 of the contact springs being visible.
  • FIG. 6a Another use of a plug insert element is shown in FIG. 6a, in which a straight plug 21 is used as the plug housing, in which the plug insert element is held in a corresponding manner.
  • 6b shows the top view in the direction of arrow R on the plug insert element shown in FIG. 6a, again with the contacting curvatures 18.
