Definitions

  • the invention relates to a flat receptacle for the electrical connection of a Cable or the like with a flat plug, with one from a base plate and two opposite, upstanding side walls existing receiving space into which the flat plug can be inserted from one end with the free edges of the side walls above the base plate bent inwards towards the base plate and both longitudinal edges the free edges of the side walls are rounded at least on one side are designed to form a linear contact on the top of the Obtain tab connector, the rounded longitudinal edges near the contact the axial center line of the blade receptacle, as well as on the base plate through two parallel to each other in the receiving space Pointing characteristics of the base plate areas for linear Contact with the flat connector and a locking device is formed are over a locking lug with a recess in the tab interacts.
  • Such a flat receptacle is known from DE-GM 19 33 169. at this known, a linear contact with the tab enabling the flat receptacle, the latching takes place between the flat receptacle and the flat connector via a punctiform elevation in the Base plate of the flat receptacle. Due to the stiffness of the solid base plate the flat receptacle is on the one hand the insertion of the tab a lot of effort and on the other hand releasing the locking very difficult to reach.
  • a disadvantage of this prior art is that in addition to the increased manufacturing costs due to the higher number Bends the contact between the free edges and the top of the tab due to the new bend near the Side walls are made, which is due to the very small lever arm nevertheless, a great deal of force must be applied to the free edges when To be able to slide the flat connector upwards. But just that Push-in force is a decisive criterion for an easily mountable Plug-in connection, since the assembly personnel in particular during manual assembly quickly complains of aching fingers at high insertion forces.
  • the invention is based on the object of improving a flat receptacle of the type mentioned at the outset, avoiding the disadvantages mentioned above, in such a way that it is simple and inexpensive to produce on the one hand and on the other hand only low insertion forces are required to make contact with the plug connection without the reliability of the electrical connection suffers.
  • the object is inventively achieved in that the latching lug parallel on a two, formed transverse to the insertion of the tab cut-outs being arranged in the receiving space in curved locking clip and formed the base plate in the region of the locking clip formed by the two cut-outs with a smaller material thickness to increase the spring elasticity of the locking clamp.
  • the locking lug on one by two parallel cutouts formed, arranged in the receiving space bent locking clamp. Furthermore, the base plate is in the area through the two cutouts formed locking clamp with a lower material thickness designed to increase the spring elasticity of the locking clamp.
  • the Reducing the stiffness of the locking clamp also helps that the insertion force is reduced because it is in the contacted state in Area of the locking clamp and the latch for a friction contact comes with the inserted flat plug. Because of the lesser Material thickness, which can be achieved for example by forging, becomes the spring elasticity of the locking clamp in the area of the latch clearly increased.
  • they are the locking clamp forming cutouts transverse to the insertion direction of the tab and the characteristics causing the linear contact the base plate is formed parallel to the side walls.
  • the transverse orientation of the locking clamp is particularly good narrow locking clamp and therefore only a small friction surface between locking clamp and flat plug.
  • the cutouts transverse to the insertion direction of the tab formed between the forms formed parallel to the side walls are.
  • Expressions according to this embodiment not by the cutouts are interrupted, on the one hand, a flawless and uninterrupted Contact between the inserted flat plug and the flat plug sleeve reached and on the other hand facilitates the insertion of the tab, since the contact along the characteristics is continuous, that is, without additional approaches are made through the cutouts.
  • the invention proposed that one of the insertion opening for the edge of the locking clip facing away from the flat connector into the locking clip delimiting section protruding arched is.
  • a locking clamp designed in this way enables in addition a suspension of the entire locking clamp perpendicular to the direction of insertion of the tab connector a tilting spring movement of the front, arched trained part of the locking clamp. This additional spring movement causes higher pulling forces are required to the connector to solve again.
  • the insertion force can be according to a further embodiment of the invention still be lowered in that by the longitudinal edges of the free
  • the upper contact lines formed by the edges and those formed by the characteristics formed lower contact lines laterally offset from each other are. Through this staggered arrangement of the contact lines, the Bending stress distributed over different areas of the flat receptacle and equalized, which in turn is used to insert the tab force is reduced.
  • Figures 1 to 7 show that the made of electrically conductive material Connection 1 from a flat receptacle 2 and a flat plug 3 exists, which is inserted into the flat receptacle 2.
  • the locking of Flat receptacle 2 and flat plug 3 is replaced by one of the flat receptacle 2 protruding and in a recess in the flat plug 3 recess 4 penetrating latch 5 ensures, as shown in Fig. 3.
  • Fig. 1 shows that the flat receptacle 2, for example via a crimp connection 6th can be connected to an electrical cable 7.
  • the manufacture of the flat receptacle 2 is made from a flat sheet metal strip by punching, bending and Emboss to obtain a flat receptacle as shown in FIGS. 1 to 7.
  • the lockable flat receptacle 2 has a base plate 8 with two each other opposite, upstanding side walls 9, the two free Edges 10 above the base plate 8 are bent inwards towards the base plate 8 are to form a receiving space 11 for the tab 3.
  • the catch 5 is for locking the tab 3 on one formed by two parallel cutouts 12a and 12b Locking clamp 13 arranged.
  • the locking clamp 13 In an uncontacted state, like this one is best seen from Fig. 2, the locking clamp 13 is after bent up into the interior of the receiving space 11 in order to insert the Flat connector 3 engages the latch 5 in the recess 4 of the flat connector 3 to ensure.
  • FIGS. 4 and 6 the contact points between tab 3 and tab 2 linear.
  • the contact lines are in the area of the base plate 8 by two parallel to each other, projecting into the receiving space 11 Expressions 14 of the base plate 8 are formed, on which the tab connector 3 rests.
  • Expressions 14 of the base plate 8 are formed, on which the tab connector 3 rests.
  • the free ones Edges 10 of the side walls 9 by less than 180 ° inwards to the base plate 8 bent over.
  • This embodiment enables the Contact line of the longitudinal edges 15 on the surface of the tab 3 lie near the axial center line 16 of the flat receptacle 2.
  • one Flat receptacle are the free edges 10 of the side walls 9 by almost 180 ° bent towards the base plate 8. With such a large bend, it is necessary to round off the longitudinal edges 15 of the free edges 10 on both sides in order to at all times only a linear contact between the longitudinal edges 15 to ensure the free edges 10 and the tab 3.
  • a third embodiment of a flat receptacle 2 is shown.
  • they are the locking clamp 13 forming cutouts 12a and 12b between the parallel to the side walls 9 trained forms 14 formed. Shortened by this Formation of the cutouts 12a and 12b becomes a continuous and uninterrupted Contact line along the features 14 provided.
  • This shortened formation of the cutouts 12a and 12b and thus also the Locking clamp 13 has the consequence that the locking clamp 13 in uncontacted state more bent upwards into the receiving space 11 is than this when the cutouts 12a and 12b are formed over the expressions 14 is the case.
  • This stronger suspension of the locking clamp 13 perpendicular to the insertion direction of the tab 3 causes a better clamping effect between the tab 3 and the Flat receptacle 2.
  • This arched edge 13a of the locking clamp 13 causes an increase in the amount required to remove the tab 3 Peeling forces, since in addition to the spring direction of the locking clamp 13 vertically the front, curved edge for the insertion direction of the flat plug 3 13a can perform a tilting movement, as indicated by the arrows in FIG. 9 is shown.
  • a flat receptacle 2 designed in this way is characterized by that only due to the linear contact with the tab 3 low friction forces have to be overcome and thus the insertion force for insertion the flat connector 3 is minimal. Because of the manufacturing tolerances in the formation of the bent free edges 10 of the side walls 9 can be enlarged because it is due to the rounded longitudinal edges 15th there is always a linear contact with the flat connector a flat receptacle 2 designed in this way is also simple and inexpensive to manufacture.
