Definitions

  • the invention relates to an electrical switching arrangement for the electrical initiation of an airbag.
  • Airbags are e.g. in the steering wheel or rear of a motor vehicle. In the event of a collision, the airbag should be deployed and inflated very quickly. To initiate these mechanical processes, an electrical switching system is provided that responds to certain commands.
  • the object of the invention is to provide a simply constructed electrical switching arrangement for the electrical switching system of an airbag.
  • the switching system has a plug which consists of a mating contact - for example a contact pin and a contact socket housing made of plastic.
  • a plug which consists of a mating contact - for example a contact pin and a contact socket housing made of plastic.
  • chambers are introduced in the contact socket housing, in which there are electrical connectors formed from stamped sheet metal parts and crimped on electrical lines and having contact spring arms.
  • the contact socket housing 1 shown in FIGS. 1 and 2 can be essentially cuboid. It consists of an outer casing 2 and an inner casing 3.
  • the inner housing 3 has the side walls 4, 5 and two front walls (the front walls are not shown because they can be of any design). Furthermore, the inner housing 3 has a top wall 6 and a bottom wall 7.
  • the inner housing 3 is so wide that two rows of contact chambers 8, 9 are arranged next to one another in the longitudinal direction and have chambers 10a and 10b arranged at a distance from one another in the longitudinal direction, each chamber 10a looking at the associated chamber 10b in plan view (FIG. 2 ) are staggered. This arrangement results in a central longitudinal wall 26 between the contact chamber rows 8, 9.
  • the chambers 10a, 10b extend continuously from the top wall 6 to the bottom wall 7 and are essentially rectangular in cross section.
  • the chambers 10a, 10b each open into the top wall 6 and a plug opening 11 for inserting the electrical connector 16 and in the bottom wall 7 with a plug opening 12 with a finding funnel 13 for inserting contact pins (not shown).
  • the connectors 16 are fixed in the chambers with a detent spring 20 which is arranged on the contact spring arm base 22 and which engages behind an edge 21 in a chamber 10a or 10b.
  • the edges 21 lie approximately in the longitudinal center of the chambers 10a, 10b, of which the upper half 14 extend upwards and the lower half 18 downwards.
  • the connectors 16 are equipped with an over-spring, with over-spring arms 24 pointing from the over-spring arm base 22 to the insertion opening 12, which are supported on the contact spring arms 23 of the connector 16, the over-spring arm base 22 being positively seated on the spring arm base (not recognizable) of the electrical connector 16 .
  • the claw area 19 of the connector 16 is connected to the spring arm base via a short-circuit contact web 25 which is arranged offset to the outside in relation to the longitudinal center axis 26 of the connector 16.
  • the connectors 16 in the row 8 are arranged in mirror image to the connectors 16 in the row 9 such that the short-circuit contact webs 25 are adjacent to the side walls 5a and 4a of the upper half of the inner housing 3.
  • the inner housing 3 can also be divided externally into an upper and a lower half by thinning the side walls 4a, 5a of the upper half are formed as the side walls 4b, 5b of the lower half, the side walls 4a, 5a springing back and forming a step edge 27.
  • slots 28 extend in the walls 4a, 5a in the area of the chambers 10a, 10b in the direction of the top wall 6 up to approximately the height of the claw areas 19 of the connectors 16, so that the shorting bridge webs 25 are accessible from the outside.
  • the short-circuit bridge is formed by a short-circuit bridge bracket 29 with a U-shaped cross section according to FIGS. 1 and 2 from a stamped sheet metal part.
  • the bracket 29 has a bridge base web 30 and two spring arm legs 31, 32 connected to it laterally.
  • the bridge base web 30 rests on the top wall 6 of the inner housing 3, while the spring arm legs 31, 32 expediently bear against the side walls 4a, 5a in the area above a slot 28 in each case.
  • each connector 16 of a chamber 10a is electrically connected to a connector 16 of a chamber 10b through the shorting bar bracket 29.
  • the contact edge 33 of the spring arm leg 31 is expediently arranged at the same height or at the same level as the contact edge 33 of the spring arm leg 32.
  • a recess 34 is made which extends in the longitudinal direction of the inner housing 3 and begins at the insertion opening 12 and goes up to step 27 or to the beginning of the slots 28, whereby the corresponding free Leg 35 of the V-shaped bend 33a of the short-circuit bridge bracket 29 is longer and protrudes beyond the recess 34.
  • a corresponding groove can also be arranged in each chamber 10b.
  • a separating slide 36 which is integrally formed on the contact pin housing, not shown, projects into the extension 34.
  • corresponding grooves are provided in the chambers 10b instead of the recess 34, corresponding separating pins are formed on the contact pin housing.
  • the isolating slide 36 is pushed into the inner housing 3 to such an extent that it cancels the contacting of the spring arm arm 32, i.e. the edge 37 presses against the slope of the free leg 35 and supports the spring arm leg 32 at a distance from the associated short-circuit contact web 25.
  • the isolating slide 36 also slides and releases the spring arm leg 32 so that the spring arm can spring against the short-circuit contact web 25 and thereby cause a short-circuit.
  • the spatial shapes are adjusted to one another in such a way that the short circuit is established before the contact between the contact pins (not shown) and the spring arms 23 is interrupted.
  • the bridge base web 30 is accordingly designed to run diagonally (see FIG. 2), the bridge base web 30 in each case having a semicircular punching 39 in the region above a plug-in opening 11, which is penetrated by a line 15. Accordingly lie the bends 48, 49 of the spring arm legs 31, 32 diagonally opposite one another.
  • an outer housing 40 with side walls 41, 42 and longitudinally extending top wall webs 43 sits on the upper half of the inner housing 3.
  • the side walls 41, 42 overlap the corresponding side walls of the inner housing 3 and sit on the step edge 27, with the top wall webs 43 in Press the area of the bends 48, 49 onto the bracket base web 30 so that the short-circuit bridge bracket 29 is held in place by means of the surrounding housing 40.
  • the outer casing is e.g. circumferential handle bar 44 equipped, which facilitates handling.
  • the inner surface of the side wall 41 is closely adjacent to the spring arm leg 31.
  • the inner surface of the side wall 42 is formed offset to the outside, so that a space 45 is formed, into which the spring arm leg 32 can pivot when the separating slide 36 is inserted with the contact pin housing and in which the spring arm leg 32 can rest when the isolating slide 36 is fully inserted.
  • the short-circuit bridge arrangement shown in FIGS. 3 and 4 is the same as the short-circuit bridge arrangement shown in FIGS. 1 and 2 except for the spatial shape of the short-circuit bridge bracket. For this reason, the individual parts of the short-circuit bridge arrangement are not provided with code numbers again.
  • 3 and 4 does not consist of a stamped sheet metal part, but of a spring wire 46, the base web 47 being bent such that it does not overlap any of the plug openings 11 or is respectively arranged on the edge webs between the plug openings 11, and the bends 48, 49 of the spring arm legs 31, 32 viewed in plan view (FIG. 4) are arranged diagonally opposite one another.
  • grooves 50 for example semicircular grooves, are provided in the cross section of the wire shape for mounting the spring arm legs 31, 32, and if preferably in addition to the top wall webs 43 of the surrounding housing 40, the inner surfaces of the side walls 41, 42 of the surrounding housing 40 Press at least in the upper area or in the area of the bends 48, 49 from the outside against the spring arm legs 31, 32, so that the short-circuit bridge bracket 29 is immovably supported.
