Definitions

  • the invention relates to a box spring.
  • a known box spring has a contact area consisting of a box which is open at the top and U-shaped in cross section and on which a ceiling wall is supported as a separate part.
  • the wall is bent inwards, with the deepest point in the middle and serving as a contact point.
  • the wall should also ensure the spring forces required for the contact pin.
  • This known embodiment of a box spring has no sufficient spring action and it is difficult to manufacture.
  • a known contact spring is described in DE-A-30 14 614 and shown in the drawing.
  • this known embodiment there is a risk that the spring arms of the box spring are bent over, whereby the suspension is impaired.
  • the object of the invention is to provide a box spring, the contact point of which lies in the region of the plug-in opening, which ensures optimum suspension of the spring arms and which is easy to produce.
  • the invention provides to combine a flat fork spring with an over-spring with special over-spring arms.
  • the combination of a flat fork spring with an over-spring is known per se from DE-A-32 48 078, but this known embodiment is a relatively large contact element and not a miniaturized form.
  • the flat fork spring is designed as a double-arm flat fork spring.
  • the spring is box-shaped and has four spring arms that extend forward.
  • a detent spring arm that extends opposite to the spring arms is cut out from the box shape of the spring.
  • the Overspring rests on the double flat spring by cutting-in tabs in its rear edge area and engaging behind the edges of the spring arm base of the double flat spring and also bent webs in the area of the connection of the spring arms against the front edge of the spring arm base of the double flat spring.
  • This known contact element in miniaturized form is not readily usable for the purposes of the invention because it is too bulky.
  • the new miniature box spring consists of the flat fork spring 1 and the spring 2.
  • the flat fork spring 1 has a conductor connection part 3, which is only shown schematically and can be a conductor claw or a soldering element or a clamping cutting element or the like.
  • the conductor connection part 3 merges into a spring arm base 4 with a U-shaped cross section, which has a base 5 and two side walls 6.
  • a spring arm 7 is connected to each side wall and extends forward.
  • the spring arms 7 are bent starting to converge from the side walls 6 and touch in a contact line 8.
  • the spring arms 7 diverge again from the contact line 8 and form a finding funnel 9.
  • the contact is provided for the preassembly state of the flat fork spring. The purpose of this pre-assembly position is explained below.
  • the expanded position of the spring arms 7 shown in dashed lines in FIG. 1 represents the position of the spring arms in the assembled state of the box spring.
  • the spring arms 7 are made wider than the height of the walls 6, a step 10 being provided in the transition area.
  • a short tab 11 extends from the bottom 5 to the front.
  • a tongue 12 which extends forward is cut into the base 5 in the direction of the conductor connection part 3 at a distance from the step 10 and is bent outwards.
  • the over-spring 2 is preferably made of steel and is essentially box-shaped with a bottom 13, a top wall 14 and two side walls 15.
  • the top wall 14 has the production-related abutting edges 16.
  • the side walls 15 and the bottom 13 are extended to the rear and form a bearing element 17 with a U-shaped cross section with the side wall webs 17a and the bottom web 17b with the rear edge 17c.
  • the side wall webs 17a have a short incision 18 directed towards the floor web 17b in the connection area.
  • a detent spring arm 21 connected in the region of the plug-in opening 20 is cut free and bent outwards. Furthermore, there are 2 cutouts 22 and 23 in the longitudinal edge area of the box shape of the spring, the cutouts 22 in the area between the top wall 14 and the side walls 15 being shorter than the cutouts 23 in the area between the bottom 13 and the side walls 15. All four Cutouts 22 and 23 extend rearward from the rear edge 24 of a resulting front box web 25.
  • the free cuts 22 end at a distance from the incision 18, while the free cuts 23 extend to the level of the incision 18 or the bottom web 17b.
  • the corresponding cutout 23 on the right-hand side in plan view (FIG. 3) with an L-shaped cutout 23a preferably forms the cutout for the detent spring arm 21 arranged in the base 13.
  • the spring arms 26 are formed, which are bent towards one another to a defined distance. This distance corresponds about the outside distance of the finding funnel 9 of the flat fork spring 1 in the preassembly state.
  • the rear edge 24 is lengthened by embossing and forms a stop web 28 for the spring-over arms 26, which serves as protection against bending over.
  • the spring-over arms 26 are preferably cut out in an arc starting from the base towards the free end region.
  • the top wall 14 has in the area of the box web 25 on both sides next to the abutting edges incisions 29 running parallel to it.
  • the webs 30 resulting from these incisions 29 are bent inwards.
  • the distance between the cut edges of the webs 30 is equal to the desired distance between the spring arms 7 of the flat fork spring 1 in the contact line 8 in the assembled state of the box spring.
  • such incisions are present in the floor exactly under the incisions 29, from which a web 31 results.
  • the web 31 is also bent inwards.
  • the distance between the cut edges of the web 31 also corresponds to the desired distance between the spring arms 7 in the assembled state of the box spring according to the invention.
  • the spring arms 26 press on the fork spring arms 7, which are supported laterally with the lateral end regions of their contact line 8 on the cutting edges of the webs 30 and 31, which results in a defined distance between the contact line 8 of the fork spring arms 7 and a defined spring force.
  • the fork spring arms 7 can with their funnel area support on the outside on the plug opening side edge 32 of the box web 25, so that an overbend of the fork spring arms 7 can be avoided.
  • the over-spring 2 bears firmly on the flat fork spring 1 by the side wall webs 17a of the bearing element 17 being bent towards the axis 19, so that the cut edge of the side wall webs 17a resulting from the incision 18 engages behind the step 10 of the side walls 6 of the spring arm base 4 of the flat fork spring 1, and by the front edge 12a of the tongue 12 of the spring arm base 4 of the flat fork spring 1 abutting the rear edge 17c of the bottom web 17b of the bearing element 17 of the spring 1.
  • the assembly of the spring is easy because the fork spring arms 7 and the spring arms 26 do not interfere with each other.
  • the spring 2 is pushed over the fork spring, from the front over the finding funnel 9.
  • the finding funnel 9 fits approximately through the gap between the spring arms 26.
  • the length of the spring arms 26 is dimensioned such that they are in the constriction area of the contact point during assembly of the finding funnel are when the webs 30, 31 begin to expand the funnel, the spring arms 26 being arranged at a distance from the fork spring arms.
  • the fork spring arms only press against the spring arms when the widening is complete and the rear edge 17c of the spring spring 2 has hit the front edge 12a of the tongue 12 of the fork spring 1.
  • the spring force of the fork spring arms 7 can also be ensured in an optimal and defined manner, because the fork spring arms 7 are brought from a more or less relaxed position into a slightly tensioned, defined position during assembly.
  • the tab 11 in the bottom 5 of the flat fork spring 1 serves for the detent spring arm 21 of the spring 2 as an abutment against bending.
  • the box spring according to the invention acts with e.g. a square contact pin with 0.6 mm cross-section edge length for electronic components.
