Definitions

  • the invention relates to a clipboard for electrical or electronic devices, e.g. Overcurrent circuit breaker with the features of the preamble of claim 1.
  • Such devices generally consist of an insulating base plate with at least one insertion recess for inserting and / or clamping projecting tongues protruding from a lower part of the device, wherein at least one contact spring is arranged in each insertion recess to act on the contact tongues and connected to connecting means for connecting lines that usually protrude from the back of the clipboard.
  • the invention has for its object to design a clipboard in particular for fuses and overcurrent circuit breakers such that devices of different types, in particular with a different arrangement of contact and mounting elements can be brought into functional connection with the clipboard. This object is achieved by the characterizing features of claim 1.
  • the arrangement of the recesses, the attachment of the contacts in the recess, the arrangement of the screw sleeves and the arrangement of the spring hooks located in the central region of the insertion recesses enable assembly and a functional electrical interaction of the clipboard with fuses and overcurrent protection switches of different designs.
  • relatively heavy devices can be attached and electrically contacted by screwing their contact elements into or on the screw sleeves.
  • the attachment of small automatic circuit breakers is possible in that they are inserted with a foot part into the insertion recess, engage there with contact tongues protruding from the foot part between the resilient contact legs and lock behind the spring hooks for fastening with locking lugs. As a result, such automatic circuit breakers are kept in good electrical and mechanical connection with the clipboard. ⁇
  • simple fuse links can also be used in connection with the clipboard, which essentially consist of a more or less fully immersed fuse body from which two contact tongues protrude on both sides. Locking such a fuse with the spring hook is not necessary due to the low mass of such fuse links.
  • Claim 2 teaches a permanent, reliable and space-saving arrangement of the contact elements and their mutual electrical connection.
  • a certain spring behavior is achieved, by means of which damage when the securing elements are inserted is avoided and, in particular, manufacturing tolerances in the region of the insertion recesses are compensated for.
  • Claim 3 aims at a simple and functional type of attachment of the connection means, which protrude from the back of the clipboard. Due to the type of fastening, these can be fastened with a simple press stroke together with the associated contact spring and, if appropriate, further connecting elements in that the rear end of the screw sleeve is compressed in the form of a flange.
  • the contact springs can be pushed into the insertion opening from below and are then - using the above-mentioned self-suspension - with their side edges in grooves of the side walls, whereby they experience an additional lateral guidance.
  • Claim 6 ensures, on the one hand, that the upper side of the screw sleeves forming the contact side when fastening the contact springs and connecting means by a punching process is not too deep in the Plastic is pressed in, which can result in inaccuracies in the assembly of the fuses to be screwed or even damage to the clipboard. Due to the relatively large surface area of the sleeves due to the edge, the securing elements screwed into the screw-in sleeves are mechanically adequately supported.
  • the contact tongue lying in the slot is only acted upon selectively on both sides, whereby a sufficient contact pressure can be generated.
  • the corrugated shape of the slot also has an advantageous effect in the production of the contact tongues, since, despite the requirement for the point-like contact system, these can be produced by a simple stamping process. Due to the known feature of claim 9 - as already indicated - a plurality of the same and / or different securing elements can be mounted on one and the same clipboard as required.
  • a clipboard 1 for electrical or electronic devices essentially consists of an insulating base plate 2, in which six insertion recesses 3 are arranged along the central longitudinal axis 4 of the base plate 2.
  • the insertion recesses 3 have an elongated cross section and are arranged parallel to one another in such a way that their longitudinal axes 5 lie at right angles to the central longitudinal axis 4.
  • two contact springs 6 are arranged, which are electrically connected to connection means designed as flat plugs 7.
  • the contact springs are arranged symmetrically with respect to the central longitudinal axis 4 in the insertion recesses 3 and lie between the longitudinal ends 8 and spring hooks 10, which are arranged in the region of the recess longitudinal sides 9 for latching overcurrent protection switches in the central region of the longitudinal extent of the insertion recesses 3.
  • the spring direction 11 of the spring hook 10 runs at right angles to the longitudinal axis 5 of the insertion recess 3.
  • screw sleeves 12 are arranged outside of the insertion recesses, the centers 13 of which lie on the longitudinal axis 5 of the associated insertion recess 3 and bores 14 penetrating into the insulating base plate 2 in such a way Stigt that they rest on the front surface 15 with a radially projecting over the screw sleeve edge 16 and are fixed on the back with a flange 17.
  • Both tabs 7 and contact springs 6 consist of a stamped part bent at right angles.
  • the first angle leg 20 is slotted approximately in the middle to form two resilient contact legs 21 and is inserted from the rear 28 into the associated insertion recess 3, which is designed as a recess extending through the clipboard 1.
  • the second angle leg 22 is provided at its leg end 23 with a round hole 24 through which the rear end 25 of the associated screw sleeve 12 protrudes.
  • the tabs 7 also have an angled bend 27 at their fastening end 26, which is arranged parallel to the second angle leg 22 of the contact springs 6 and also has a hole through which the rear end 25 of the screw sleeves 12 protrudes. If necessary, further connection means of this type can be arranged in a corresponding manner and connected to the assigned screw sleeve 12.
  • the tabs 7 protrude from the back 28 of the base plate 2 in the direction of insertion.
  • a permanent attachment and electrical connection between flat plugs, contact springs and screw sleeves is created in that the flanging is carried out only after reaching through the flat plug fastening ends 26, so that the fastening ends 26 and the second angle legs serve as washers, as it were.
  • Bends 27 and second angle legs 22 lie in grooves 29 which are introduced into the rear 28 of the base plate 2, as a result of which the groove side edges are additionally fixed. The grooves 29 run on the connecting line of the centers 13 of the screw sleeves 12.
  • the slot 33 lying between the contact legs 21 of the contact springs 6 runs in a wavy line in such a way that a contact tongue 34 of an electrical device 40, 41 acts on one side through a first point contact and on the other side through two further point contacts and thus in a three-point holder is held.
  • the device 42 is not inserted into the insertion recess 3, but is screwed by means of contact tabs 43 on the top of the screw sleeves 12 by means of retaining screws 44.
  • Such an arrangement is particularly recommended for devices that not only have an axially effective manual push-button switch 45 for actuation, but are additionally provided with a rocker arm 46 provided for auxiliary triggering of the device 42, when actuated laterally acting forces act on the device / clipboard combination .
