Definitions
- a difficulty of this design is that the spring in Operation can reach high temperatures and that of the plastic of the Change the body formed stop due to thermal stress can. This is particularly problematic for safety relays, as in the case a contact welding the position of the stop crucial for is compliance with the safety function.
- the known Arrangement the amount of preload and the position of the counter contact spring due to the addition of the manufacturing tolerances of contact piece, Contact spring and base body are subject to large fluctuations.
- DE-B-1 185 286 and DE-B-1 002 784 are relay contact spring arrangements known in which the spring in its rest position on one abuts with its connector attached part. With this Stop part is a support that is used for contact welding to encourage the contact pair to tear open. An attitude the switching characteristic is not provided.
- the invention has for its object disadvantages, as in comparable Prior art arrangements occur, at least partially eliminate.
- a more specific object of the invention can be seen in creating a relay contact arrangement that at moderate increase in force in the overstroke range, the best possible reproducibility given spring characteristics allowed.
- the contact point between the stop part and the counter contact spring precisely defined the lead; can be correspondingly accurate according to Claim 4 the spring preload by changing the position and height of the Set the projection.
- manufacturing tolerances can be Compensate the base body against the nominal size so that it has no influence have on the spring characteristic.
- the design according to claim 5 again advantageous for manufacturing reasons.
- the measure specified in claim 6 serves to torsion the Mating contact spring when equipped with two adjacent contacts limit when opening and in the event that a contact welds. This stiffening has an advantageous effect on the remaining one Contact opening of an associated positively driven contact.
- FIG. 1A part of a relay base 10 is shown schematically, in which two connectors 11 , 12 are embedded.
- the upper end of the connector 11 ends in a recess 13 formed in the base 10 , within which the foot end of a contact spring 14 is riveted or welded.
- the free end 15 of the contact spring 14 engages in a recess 16 of a schematically indicated actuator 17 which is displaceable in the direction of the arrow.
- the contact spring 14 carries a contact piece 18 near its free end 15 .
- a counter-contact spring 20 is riveted or welded to the connector 12 within the associated recess 19, which carries at its free end a contact piece 21 which cooperates with the contact piece 18 of the contact spring 14 .
- the connector 12 is extended beyond the point at which the mating contact spring 20 is attached and forms a stop part 22.
- a spherical shape 23 is formed at the upper end of the stop part 22 , which defines the point at which the counter-contact spring 20 is supported on the stop part 22 in the rest position shown in FIG. 1A.
- a similar spherical shape can be present on the counter-contact spring 20 .
- the actuator 17 If the actuator 17 is moved to the left by a relay armature (not shown) in the direction of the arrow, it takes the contact spring 14 with it until its contact piece 18 touches the contact piece 21 of the mating contact spring 20 . During this movement, the force to be applied by the actuator 17 increases in the diagram according to FIG. 2 from point (A) along a straight line to point (B1).
- the counter contact would be in the conventional way as a rigid element 2, the force characteristic of FIG. 2 would be along the dashed line Rise line, whereby the achievable measure of the beginning at point (B1) Overstrokes would be limited.
- the point (B2) can be in the diagram of Figure 2, on which the part starts the Kochhub Schemes flat increase in force, by the prestressing with which the mating contact spring 20 abuts against the stop member 22, and by the Set the height of the shape 23 forming the attachment point.
- FIG. 3 shows the contact arrangement according to FIG. 1 in perspective, it being assumed that the contact spring 14 and the counter-contact spring 20 are each connected to the connecting piece 11 or 12 by means of two rivets indicated at 24 .
- FIG. 3 also shows the depression in the stop part 22 resulting from the spherical shape 23 .
- the embodiment according to FIG. 4 differs from that according to FIG. 3 in that a large opening 25 is formed in the stop part in the area between the rivets 24 and the shape 23 , the width of which corresponds essentially to the width of the mating contact spring 20 .
- This opening 25 prevents particles from jamming between the stop part 22 and the counter-contact spring 20 , which lead to a "wrong stop point" and could thus change the rest position and the spring characteristic.
- the embodiment shown in Figure 5 differs from that of Figure 4 in that the contact spring 14 and the counter-contact spring 20 are provided with double contacts in the form of two adjacent contact pieces 18, 21 . In this case, it is expedient to provide two adjoining features 23 on the stop part 22 . This counteracts a torsion of the counter-contact spring 20 , which could occur when welding a pair of contact pieces 18 , 21 .
