Definitions
- Electromagnetic switching device in particular a contactor, with a contact bridge support lock
- the present invention relates to an electromagnetic switching device, in particular a contactor, with a lower part, an arc chamber which can be removed from the lower part, a contact bridge support and a spring-loaded blocking element, the contact bridge support being held in the lower part, projecting into the arc chamber and being displaceable in an actuation direction, wherein the contact bridge support can be locked by means of the locking element when the arc chamber is removed, the locking element being held in the lower part and being designed as a lever which can be pivoted about a pivot axis.
- Such a switching device is known for example from DE 43 41 330 Cl.
- the known switching device already works quite well, but the locking element requires a relatively large amount of space.
- a similar electromagnetic switching device is known from DE 34 02 836 AI.
- the locking element is mounted in the contact bridge support.
- an electromechanical switching device in which the contact bridge support can be locked in its switched-on position by means of a pivotable lever, the lever being pivotable about a pivot axis which runs perpendicular to the direction of actuation of the contact bridge support.
- the object of the present invention is to further develop a switching device in such a way that it is more compact.
- the object is achieved in that the pivot axis is perpendicular to the direction of actuation.
- the storage of the locking element is particularly simple.
- the captive bracket can e.g. B. caused by that
- the contact bridge support can be freely designed without the risk of undesired getting caught before reaching the locking position.
- the blocking element is manually accessible and manually operable when the arc chamber is removed, it is particularly easy to test the switching device for proper functioning.
- the test is made even easier if the switching device has no other locking element for locking the contact bridge support apart from the locking element.
- FIG. 2 shows a section of FIG. 1 and FIG. 3 shows a locking element.
- a contactor has a lower part 1 and an arc chamber 2 as an example of an electromagnetic switching device.
- the arc chamber 2 as indicated by an arrow A in FIG. 1, can be removed from the lower part 1.
- a drive coil 3 is arranged in the lower part 1.
- a contact bridge support 4 is displaced in an actuation direction x.
- the contact bridge support 4 is mounted in the lower part 1 and projects into the arc chamber 2.
- the contactor also has a blocking element 5 which is spring-loaded by means of a spring 6.
- the spring 6 is designed as a compression spring.
- the spring 6 could also be designed as a tension or torsion spring.
- the contact bridge support 4 can be locked in the switched-off position of the contactor when the arc chamber 2 is removed.
- the locking element 5 cooperates with the contact bridge support 4 in a locking area 7.
- the locking area 7 is hook-shaped and has a run-on slope 8 at its lower end. With its hook-shaped locking area 7, the blocking element 5 engages in a corresponding counter contour 9 of the contact bridge support 4 and thereby locks the contact bridge support 4.
- the locking element 5 is designed as a lever which is pivotable about a pivot axis 10.
- the pivot axis 10 extends perpendicular to the actuation direction x. It has a semicircular bearing point 11 which can be stored in a corresponding bearing pan of the lower part 1.
- the locking element 5 is thereby guided when pivoting in a pan bearing 11.
- the locking element 5 also has a locking element 12.
- the locking element 12 can be deflected resiliently in the direction of the pivot axis 10.
- the locking element 12 cooperates with a further locking element which is arranged in the lower part 1.
- the further latching element can, but need not, be deflectable in the direction of the pivot axis 10. Due to the interaction of the locking elements 12, the locking element 5 is held captively in the lower part 1.
- the locking element 12 also has a run-on slope 13.
- the locking element 5 can thus be inserted into the lower part 1 by simply pushing it into the lower part 1 in the insertion direction y.
- the contact bridge carrier 4 When the arc chamber 2 is placed on the lower part 1, the contact bridge carrier 4 is forcibly and automatically unlocked. As indicated schematically in FIG. 2 by a finger 14, the blocking element 5 is also manually accessible and manually operable when the arc chamber 2 is removed. It is therefore possible to unlock the contact bridge support 4 with the arc chamber 2 removed and then to test the contactor for proper function. Because of the run-up slope 8, when the contact bridge carrier 4 is returned to the switched-off position of the contactor, it cannot happen that the contact bridge carrier 4 hooks with the blocking element 5 before reaching the exhibition.
- the test with the arc chamber 2 removed is particularly simple if the contactor has only a single blocking element 5, that is to say no further blocking element for locking the contact bridge carrier 4.
