Definitions

  • the present invention relates to a pin for latching fastening in a bore of a single or a plurality of planar components lying one on top of the other.
  • Fastening pins of this type are used where screws or rivets have been used since, namely for fastening, for example, electrical components to, for example, a printed circuit board, the components having a flat plastic component and / or are provided from a metal to be attached to the circuit board.
  • the components must be so securely fastened that they cannot be easily detached.
  • the fastening pin must be able to establish an electrical connection between a connection on the component and the laminated or provided with conductor tracks underside of the circuit board.
  • Such mounting pins can also be used to connect two plate-shaped components.
  • the object of the present invention is to provide a pin for locking in a bore of an individual or to create several superimposed flat components of the type mentioned, which can be easily pushed into its latching position in the relevant hole or bores of one or more components, but which cannot be pulled out again without active unlocking, the pin still being structurally simple is constructed and can be produced in a cost-effective manner.
  • both the first leg is pivoted relative to the shaft area and the second leg is pivoted relative to the first leg.
  • both legs can spring back at least partially, such that the latching area on the second leg presses against an edge area of the component in question, for example a printed circuit board. Since the locking area is provided on the bent end piece of the second leg, a pull on the pin against its pushing-in movement would have the tendency of the first leg to spring back, but not the second leg, which would move away from it instead of the first leg, which is a Increasing the width of the two catch spring legs would result.
  • the exertion of a tensile force on the pin does not lead to a loosening but, on the contrary, to a real jamming and "biting" of the pin or of its detent spring in the relevant hole. It is therefore only possible to pull the pin out of the bore if the second leg is moved in a deliberate and active manner against the first leg and then also the first leg relative to the shaft area against the spring action and is then held in this way.
  • Another advantage of the pin according to the invention can be seen in the fact that it can compensate for tolerances in the thickness of the individual components, since the latching area is formed by essentially the entire outside of the bent end piece.
  • the second resilient leg can absorb tolerances in the bore diameters, in particular of the printed circuit board, without impairing the function.
  • the first leg only has to perform a minimal deflection movement during the pushing-in movement, so that insertion into a bore can take place with less effort.
  • the pin 10, 10 'or 10 ⁇ shown in the drawing according to several exemplary embodiments is designed such that it can be latched in a bore in a flat component, such as, for example, a printed circuit board or in mutually aligned bores of two or more flat components lying one on top of the other, it being possible at the same time with the pin to firmly connect the flat components lying one on top of the other.
  • a flat component such as, for example, a printed circuit board or in mutually aligned bores of two or more flat components lying one on top of the other
  • printed circuit boards 11, fastening plates 12, plastic brackets 13 and / or metallic brackets 14 of an electronic or electrical component 15 can be considered as flat components.
  • the mounting pin 10, 10 'and 10 ⁇ is a stamped part, i.e. punched out of a metal plate and then rolled into its shape and bent.
  • the fastening pin 10 shown in FIGS. 1 and 2 has a sleeve-like body 20 which is open on the circumference and which has a shaft region 21 provided with a wide longitudinal slot 22, a detent spring 23 arranged partially within the longitudinal slot 22, two diametrically opposed insertion limiting stops 24 and 25 and a slug 26, which are from the stamping manufacture has remained.
  • the shaft region 21, which is thus seen in cross-section is essentially approximately C-shaped in such a way that it comprises an open ring along a circular arc of somewhat more than 180 °, is slightly conical over its length overall, the maximum outer diameter in the region of in the insertion direction A of the pin 10 rear end face 27 is provided.
  • the wall thickness of the pin 10 is uniform.
  • the front end of the pin 10 in the insertion direction A is provided on the outside with an insertion bevel 29.
  • the two limit stops 24 and 25 protrude from the end face 27 as outwardly bent contact tabs, the one contact tab 24 adjoining the one side edge 31 of the shaft region 21.
  • the slug 26, which projects axially beyond the end face 27, is provided approximately between the two limit stops 24 and 25.
  • the detent spring 23 extends in the axial direction.
  • the flap 33 is flat and angled from the C-shaped shaft region 21 in such a way that it extends approximately parallel to a longitudinal center plane 34 running through the limit stops 24, 25.
  • the detent spring 23 has a first leg 36 which adjoins the tab 33 and is bent at an acute angle to the inside of the shaft region 21 with respect to its vertical plane.
  • a second leg 37 adjoins this end region of the first leg 36 via an arc 38, which forms an acute angle with the first leg 36 and runs counter to its direction.
  • the second leg 37 is at its free end region with an end piece 39 directed towards the first leg 36 and bent by approximately 90 °.
  • the shape and length of the L-shaped second leg 37 is such that it leads at least with its end piece 39 Arch 40 projects beyond the outer circumference of the shaft region 21.
  • the maximum width W of the detent spring 23 or the two resilient legs 36 and 37 in the relaxed state is greater than at least the dimension that results from the inner diameter of the shaft region 21 and its wall thickness. This maximum width is given in the exemplary embodiment between an outer region of the arch 38 at the transition from the first to the second leg 36, 37 and an outer region of the arch 40 to the end piece 39.
  • FIG. 3 shows the fastening pin 10 in bores 16 and 17 of a printed circuit board 11 and a fastening plate 12 which are essentially the same size, whereby these two plates 11 and 12 are firmly connected to one another by the pin 10.
  • the arc 40 of the second leg 37 is released from the lower bore 16, so that the detent spring 23, ie both the first leg 36 and the can pivot the second leg 37 back to a certain extent, the outer side 43 of the end piece 39 of the second leg 37 forming a latching area resting against the lower free edge 44 of the lower bore 16.
  • the latching area is located at a corresponding point on the outside 43 of the end piece 39 between the curved area 40 and the end face 42. that the minimum outer diameter of the slightly conical shaft region 21 is equal to the inner diameter of the bores 16, 17.
  • the mounting pin 10 shown in Figure 4 ' is formed in essentially the same way as the mounting pin 10 of Figures 1 to 3, but with the following differences, which are described below only.
  • an abutment nose 46 is provided in an upper part of the shaft region 21 'of the fastening pin 10', which is formed by a stamping or punching from the inside to the outside on a peripheral region.
  • the second leg 37 'of the detent spring 23' of the pin 10 'on its two side edges, namely on the outside, that is, facing the bore wall with bevelled edges 47, 48 which begin after the lower arch 38 and extend beyond the arch 40 leading to the end piece 39.
  • Figure 5 shows a pin 10 ⁇ , which is used to mechanically connect the plastic bracket 13 connected to a housing 51 of an electrical component 15 with a printed circuit board 11 and also either the housing 51 or one of two connecting lines 52, 53 with the To electrically connect metal layer 54 or conductor tracks on the underside of the printed circuit board 11.
  • the pin 10 ⁇ is a combination of the above-described embodiments 10 and 10 ', in that the limit stops 24, 25 and the terminal lug 26 of the pin 10 and the recesses 47 and 48 of the detent spring 23' of the pin 10 'are provided.
  • the pin 10 ⁇ is inserted in this embodiment in the manner described above in aligned bores 16 and 18 of the circuit board 11 and the plastic bracket 23 and a bore 19 of a metal bracket 14 which is electrically connected to the housing 51.
  • the limit stops 24 and 25 rest on the metal bracket 15 and are thus electrically connected to it.
  • E.g. are behind the pin 10 'lying contact pins or sockets with one of the connecting lines 52 and 53 electrically connected.
