- a contact spring is available, which can spring in the direction parallel to a longitudinal axis of the contact spring plates and spacer elements in the clamping region, wherein by the distance of the contact spring plates in the spring region all contact springs can spring simultaneously and independently. In this way, even with an uneven contact surface, at least the number of contact spring plates corresponding number of contact points or points between the free contact end of the contact spring and the contact surface. Furthermore, there is the advantage that on uneven and / or flexible contact surfaces, for example on printed circuit boards, repeatedly (large cycles of 10,000 to 20,000 or more) one or more parallel electrical contacts can be made with high quality.
- the common plane of the free contact end is arranged perpendicular to a longitudinal axis of the contact spring plates and spacer elements in the clamping region.
- the contact spring plates expediently have two, three or four kinks in the spring region.
- the contact spring plates In this case, at least one of the contact spring plates, in particular all contact spring plates in the spring area, have at least one slot, adjacent to the slot, resilient contact tongues result independently of each other and the amps multiply free contact end free resilient contact elements, so that multiply the contact points accordingly.
- the at least one slot extends over at least one bend of the contact spring plates and preferably runs parallel to a longitudinal axis of the contact spring plates.
- the contact spring plates and spacer elements are, for example, riveted and / or screwed together in the clamping area.
- the spacer elements extend over a part of the clamping region or over the entire length of the clamping region.
- the predetermined angle between the longitudinal axis of the contact spring plates in front of the kink and the longitudinal axis of the contact spring plates after the kink is identical for all kinks.
- a substantially zigzag-shaped design of the spring region is achieved in that, in the spring region, the predetermined angle between the longitudinal axis of the contact spring plates before the kink and the longitudinal axis of the contact spring plates after the kink, starting from the clamping region in the direction of the contact end, increases for a first kink 90 ° and for each additional bend is less than or equal to 90 °.
- the sum of the angle 28 of two successive bends 24 is equal to or greater than 180 °.
- FIG. 1 shows a preferred embodiment of a contact spring according to the invention sectional view
- 2 shows the preferred embodiment of a contact spring according to the invention according to FIG. 1 in plan view

- Fig. 5 is a contacting element with a plurality of inventive
- FIG. 6 shows the contacting element according to FIG. 5 in a partially cutaway side view.
- the contact spring plates 12 are held fixed in a clamping region 16, each with a spacer element 14 between two adjacent contact plates 12. For this purpose, a stack or a package of alternately arranged on each other contact spring plates 12 and spacers 14 by means of rivets 18 with each other.
- the spacer elements 14 extend only over the clamping region 16.
- the contact spring plates 12 extend beyond the clamping region 16 and form a spring region 20 between the clamping region 16 and the contact end 10.
- the contact spring plates 12 are spaced apart from each other by the thickness of the spacer elements 14 and thus spring freely and independently of each other, as long as they do not abut each other due to the spring travel. Furthermore, the contact spring plates 12 are formed such that they extend over the entire length of the spring region 20 between the contact end 10 and the clamping region 16 parallel to each other. At the free contact end 10, the contact spring plates 12 end in a common plane, which is aligned perpendicular to a longitudinal axis 22 of the contact spring plates 12 in the clamping region 16.
- the space between the contact sheets 12 is empty, i. There is also no spacer 14 is provided, as shown in particular in FIGS. 3 and 4. This free space is used for compressing the contact spring in the direction of the longitudinal axis 22nd
- the contact spring plates 12 in the spring region 20 at least one kink 24, each having a predetermined angle 26, 28 between the longitudinal axis 22 and 23 of the contact spring plates 12 in front of the kink 24 and
- angle is meant between two longitudinal axes 23 of the respective smaller of the two complementary angles at a bend 24, as shown in Figs. 3 and 4.
- the contact spring plates 12 are each provided with a slot 30.
- the spring travel of the contact spring according to the invention is adjusted with the thickness of the spacer elements 14.
- the hardness of the spring is adjusted by the thickness and width of the contact spring plates 12 and by the number of contact spring plates 12.
- the high-current contact spring according to the invention is characterized by a very low contact resistance with a sufficiently large material cross-section and low spring stiffness.
- the contact spring is preferably suitable for touching (contact) on flat surfaces, such as pads or contact surfaces of printed circuit boards.
- the contact spring shown by way of example in the figures has eleven contact spring plates 12 and ten spacer elements or intermediate plates 14. Through the central slot 30, the resulting through the slot 30 left and right contact spring half spring independently. As a result, both spring halves contact securely on the contact surface.
- the contact spring remains but laterally stable. It may be provided depending on the application, two, three or more slots 30, resulting in a corresponding tripling, quadruple or multiplication of the independently resilient contact spring halves.
- the spacers or intermediate plates 14 provide the necessary flexibility in compression by ensuring a sufficiently large gap 32 between the contact plates 12.
- the many independently resilient contact points form the basis for a low contact resistance, since the contact pressure at each contact point is uniformly high.
- the contact spring according to the invention comprises a block of S-shaped bent contact spring plates or individual springs 12, wherein the resilient geometry is identical in all contact springs or individual springs 12 of the block.
- individual contact plates 12 may have additional cross sections (attachments). It results in an advantageous manner, a low contact resistance, a rigid contact perpendicular to the working and contacting plane and a soft spring with a large material cross section and a compact overall size.
- the spring stiffness is essentially determined by the material thickness and the number of contact spring plates or individual springs 12. 5 and 6 show a contacting element 34, which has a plurality of contact springs according to the invention, in order to produce a plurality of mutually separate electrical contacts in parallel.
