Definitions

  • the present invention relates to a relay positively driven contacts for mains voltage after the The preamble of claim 1 or 2.
  • the invention relates also a method of making the relay.
  • the contact springs must be used to mount this relay be placed in a prefabricated holding part. Then it will be this holding part equipped with contact springs and one Magnetic coil with core and yoke together in one Injection molding system cast into a single part.
  • the contact springs should preferably be straight be guided to facilitate adjustment of the relay.
  • this is achieved in that the contact springs next to the tax side with one for your Adjust sufficient, minimal distance to the partition arranged and the output contacts with each other at least with a protection against dangerous body currents sufficient insulation are separated by the partition on the comb side of the coil former along the one isolated there
  • the bobbin is extended.
  • the contact springs between the contact head are advantageous and clamped foot end straight for better adjustment and not susceptible to different operating temperatures to be.
  • the coil with the plastic is advantageous on all sides molded around the carrier part or poured into the plastic. This makes the coil, and advantageously also the core with the coil and yoke, immovably fastened in the carrier part, so that the Location of the individual parts of the relay and the distances between them are unchangeably defined.
  • the carrier part is advantageous for tax and Output side manufactured in one operation, so that as few individual parts as possible have to be manipulated.
  • the creepage and clearance distance is advantageous for the through the comb moved ends of the output contacts around the Partition through a groove in the partition and one Cover, preferably in the form of a support member inserted hood, with perpendicular to the partition and parallel facing the comb and with one on this Rib arranged on the top side engaging in the groove extended labyrinthine.
  • the partition needs no further over the movable end of the contact springs Be extended, as is room for the anyway Forced guidance with the comb is required.
  • the air and the creepage distance is with groove and rib over the coil body very small space extendable for double insulation.
  • the contact springs of the two are advantageous opposite, parallel to the partition Sides of the relay can be inserted into the carrier part. Thereby are they simple, e.g. through an interaction a bulge in the carrier part and a recess in the Contact spring or vice versa, precisely fixable in height.
  • the clearances and creepage distances are expediently between the output contacts on the same side of the partition extended by partitions perpendicular to the partition.
  • the comb advantageously has a comb in two arms dividing incision on which arms each with the Contact springs on another side of the partition in Are intervention. It is also advantageous to open the partition a nose opposite each other trained which lugs on the facing away from the relay Side of the comb are arranged, and that the distance of the Tips of the two noses is larger than the width of the Incision. This will keep the comb in place after being inserted into it Carrier part is tight behind the noses and is nevertheless slidable. Is advantageous between the poor and that Incision formed at least one spring member on the comb, which interacts with the nose. These spring means give way when the comb engages in the carrier part, and enable it to snap into place without the arms of the Comb may run the risk of being deformed.
  • a carrier part for the electrically conductive parts of the control side and the Output side manufactured in one piece and a magnetic coil the manufacture of the carrier part poured into this. This eliminates the need for various casting processes Production of various parts of the carrier part and the Coil with core and yoke is fixed in the plastic mass. This also creates rigid relationships, which at such precision objects are estimated.
  • the contact springs are advantageous from the two opposite sides parallel to a partition of the relay inserted into a clamping groove in the carrier part. This enables them to be retrofitted and able precisely fixable.
  • the comb is then advantageously placed in a Guide engaged, in engagement with the contact springs brought, and the function of the relay before putting on the Cover or hood checked. This allows the relay to be adjusted during and / or after the check. Is however, only with the hood closed Functional check possible, otherwise the comb will not is held or guided, is the intervention in the relay based on the measurement data found during the check much more difficult.

  • the partition wall 47 is in the support part 19 on both sides Clamping grooves 51 formed in a foot part 53. In the Clamping grooves 51, the contact springs are inserted and therein fixed. Between the contact units 13/13 'and 14/14' and 15/15 'and 16/16' are partitions 55 for Extension of air and creepage distances provided.
  • the carrier part 19 is shown empty.
  • Figure 3 shows the anchor-side end.
  • As a metallic Surfaces are only on the surface of the carrier part 19 the two yoke parts 25, 25 'are visible.
  • For the anchor is one Niche 57 formed in the carrier part.
  • the anchor comes with a Anchor retaining spring, not shown, in the niche 57 held.
  • the anchor retaining spring sits in the two Recesses 59 on the niche sides.
  • the niche 57 merges into the guide 35 at right angles.
  • An extension 61 of the is located in the middle of the guide Partition 47. On the extension 61 there are lugs 63 formed, which with the spring members 43,43 'on the comb 31st cooperate and hold the comb 31 in the guide 35.
  • control side Groove 65 formed to form a catchment space between the hood and the carrier part 19 as a capillary barrier for intrusion To form flux or other dirt.
  • the hood 67 is shown in FIGS. 5 to 7.
  • the Hood 67 comprises the carrier part 19 with all of it and in it arranged parts on five pages. It is from the inserted on the comb side over the carrier part and closes relatively close around the foot part 53 and the groove 65.
  • the attached hood 67 holds the anchor retaining spring in place firmly and definitely prevents the comb 31 from coming out again the guide 35 can jump.
  • On the cover side 69 a rib 71 is formed, which in the groove 49 in the Partition 47 fits.
  • the rib 71 is as long as the groove 49 and is connected to the front side wall 73 of the hood 67.

In other words, they have an upper one Extension 85 above the contact head 81, which by the The size of the recess is narrower than the spring plate. This extension 85 is engaged with the comb 31. Sie is narrower than the rest of the spring plate because it is on the one hand does not have to carry electricity and on the other hand the space for the Rib 71, the septum 47, the comb 31 and the The space between the partition and comb is very narrow. This can reduce the depth of the relay and the comb be placed on the spring plate.
