Definitions

  • the invention relates to a spacer for an electrical contact spring set with at least three contact springs arranged one above the other / next to one another at certain intervals, the spacer keeping the two outer contact springs at a certain distance from one another in the region of the contact points, while the middle contact spring, which is formed by a switching star, in particular an electromechanical timer, controlled, can be switched between the two outer contact springs.
  • the middle contact spring has a relatively large through hole for the spacer and its freedom of movement during the contact switching operation (eg CH-A-434 423). Through this through hole, the spacer must not only be pushed during assembly on the spring contact set, but this through hole considerably weakens the cross section of the central contact spring.
  • the invention has for its object to provide a spacer that does not contain these disadvantages, in which the contact springs do not contain cross-sectional holes, which can be easily manufactured and which can in particular be mechanically mounted on a spring contact set without after assembly the contact springs must be readjusted.
  • the comb-shaped design of the spacer makes it easy to plug on possible on the contact springs, without these having to be bent to an extent that readjustment would be necessary. With this comb-shaped spacer, it is also possible to carry out the assembly of the spacer using a machine-guided tool. Another advantage is the simple manufacture of this spacer, which can be produced from an insulating material both by injection molding and by stamping.
  • the new spacer which can be injection molded from a plastic, in its comb-shaped design with three incisions 2 and 3 which are open on one side and which are all open to one another, depending on the view are arranged in parallel.
  • the two outer incisions 2 are made at the desired distance between the two contact springs, not shown in this figure.
  • the width of the outer incisions 2 corresponds to the thickness of the sheet thickness of the contact springs. If necessary, this incision width can also be a fraction larger than the sheet thickness.
  • latch-shaped securing elements 7 are provided, which limit the depth of an incision on the open side, this total incision depth corresponding to the height of the outer contact springs, as the following figure shows. 17 denotes a so-called run-in slope on the edge 11 of the two outer webs 14 of the spacer 1.
  • the middle incision 3 is expediently larger there than the switching path of the middle contact spring, as shown in FIG. 2 in more detail.
  • the two walls 9 are effectively designed as spring elements and are accordingly evaded when the spacer is attached to the contact springs 4, which are thus fixed at the desired distance from one another and to the central contact spring 5.
  • the spacer is secured by the latch-shaped securing elements 7 on the contact springs 4 in a positionally secured manner.
  • two tab-shaped securing elements 8 which are raised at a distance from the thickness of the spacer 1 on a narrow side of the contact spring 5 and which limit the spacer with little longitudinal play in the region of the contact points 6 on both sides, are punched out on the middle contact spring 5 .
  • the cross bar 15 of the spacer 1 can engage in corresponding notches of the outer and / or the middle contact spring 4, 5 for longitudinal securing of the spacer. It is also contemplated that a safeguard against removal or falling of the spacer from the contact set instead of the latch-shaped securing elements 7 can be formed from bolt-shaped securing elements on the walls 9, which engage in holes provided in the contact springs 4.
  • latch-shaped securing elements 7 are provided opposite one another in the area of each of the outer incisions 2, all the webs 14 and walls 9 being designed to be resilient.
  • Fig. 3 denotes the two outer contact springs and 5 the middle contact spring, which together in one side an insulating material carrier 16 are injected, inserted or riveted.
  • 1 denotes the spacer and 18 contact rivets on the contact springs 4 and 5.
  • 8 denotes the two tab-shaped securing elements on the narrow side of the contact spring 5 for the longitudinal limitation of the spacer.
  • FIG. 4 it can be seen how the spacer 1 is snapped onto the spring contact set and fixed in position. 7 there shows a latch-shaped securing element which engages behind the contact spring 4. 8 denotes the tab-shaped securing elements, which are arranged in a raised manner on the central contact spring 5 and fix the spacer in the longitudinal direction of the contact spring.
  • the invention is not limited to spring contact sets with only three contact springs, but it is intended to use the design of the new spacer also for spring contact sets with more than three contact springs arranged one above the other / next to one another.
