Definitions
- the invention relates to an arrangement for busbar and fixed contact attachment for electrical switching devices, in particular contactors, wherein each conductor rail or connection lug on one side of a rail support housing is attached with a screw and on each of the Rail carrier housing attached terminal lug a pre-assembled fixed contact carrier with commutation plate and contact piece using a Screw is releasably attached, and each terminal lug and the rail support housing with corresponding holes for receiving the screws is equipped.
- Each terminal lug on one side of a contact carrier housing is attached using a screw and on each of the contact carrier housing attached connecting lugs becomes a pre-assembled fixed contact carrier with commutation plate and contact piece using a Screw releasably attached. Furthermore, each end flag and the contact carrier housing with corresponding holes for receiving the screws equipped.
- Each connection lug has two threaded holes and can be screwed to the contact carrier housing using a screw. Means the other screw is the fixed contact carrier with the connection lug and screwed to the contact carrier housing. From U.S. Patent 4,288,669 a threaded plate integrated in the fixed contact carrier is known.
- the invention has for its object a To create busbars, terminal lugs and fixed contact attachment, which is a simple assembly both with respect to the assembly process of the entire structure.
- each connection lug on the the fastening side opposite side of the rail support housing a threaded plate is assigned with two threaded holes, the threaded holes of the Thread plate corresponding to a diameter and a distance from each other have the holes formed on the terminal lug, and the connection lug by means of a screw with the threaded plate and the Rail carrier housing can be screwed and the fixed contact carrier with the Connection flag, the rail support housing and the threaded plate by means of another screw can be screwed.
- connection flag or busbar by means of a screw on the rail support housing to fix and further the fixed contact carrier with a to fasten a single additional screw in the desired position, in such a way that it is without the busbar or connecting lug to solve, even for the purpose of changing the contact piece detachable and interchangeable is.
- for the attachment of each fixed contact carrier only one screw needed, i.e. both in the case of assembly and in In the event of disassembly, only one screw has to be loosened.
- the connection flag is only attached to the housing with a screw, and can only be removed after disassembly of the fixed contact carrier are disassembled or is installed before the Fixed contact carrier self-assembled with a screw.
- the invention Solution is by using the threaded plate as a counter bearing to the busbar or connecting lug on the opposite side of the Rail support housing on which the busbar or terminal lug rests enables.
- An embodiment according to the invention proposes a fixed contact carrier with a U-shaped commutation plate is equipped, the two U-legs parallel to Extend terminal lug and in its spaced from the terminal lug upper U-leg a V-shaped cutout is formed.
- the fixed contact carrier to be axially with the V-shaped Recess of the commutation plate has aligned bore that also the U-leg of the commutation plate resting on the fixed contact carrier interspersed in such a way that the fixed contact carrier with the threaded plate and the rail support housing by means of a through the V-shaped Recess guided screw is screwed.
- the invention enables simple assembly with little assembly time because only one when installing the fixed contact carrier and the connecting lugs Mounting direction is provided for the screws and each for attaching the connecting lugs or the fixed contact carrier only one screw each is required, i.e. with six connections, six screws for the connection lugs and six screws for the fixed contact carrier and per connection a threaded plate.
- a fixed contact carrier 5 is shown in perspective, with a U-shaped commutation plate 6 with two legs of different lengths 63, 64 is equipped, the longer U-leg of the fixed contact carrier 5 is spaced and this protrudes forward.
- the longer one upper U-shaped leg 63 of the commutation plate 6 also has a V-shaped recess 62 in the area opposite to free end of the leg, the contact piece 8 is attached.
- the contact carrier 5 is provided with a through bore 52 which also includes the lower leg 64 interspersed with the commutation plate, the V-shaped Recess 62 and the bore 52 in the vertical direction, see arrow B, with each other swear.
- a terminal lug 3 is shown in perspective, with two Through holes 31, 32 for attachment to the rail support housing 1 and is equipped for attaching the fixed contact carrier 5.
- Fig. 1c the assignment of one fixed contact carrier 5 is schematic a terminal lug 3 shown such that the fixed contact carrier the inner end of the terminal lug 3 is seated and by means of the inner end arranged bore 32 inserted screw 7 is fixed.
- the Rail support housing 1 shows according to the number and configuration the terminal lugs 3 corresponding receiving pockets 12, in this case six pieces, in which the connecting lugs are first inserted in the direction of arrow A. and then on the mounting side 11 or top 11 of the Support the rail support housing 1. Then the connecting lugs 3 in each case by means of one inserted through the bore 31 in the direction of arrow A.
- connection lugs 3 are located on the top of the rail support housing, being both the connection plates, the bottom of the rail support housing and the threaded plates associated with each other hole or threaded holes are equipped.
- outer Screws 4 inserted to the connection lugs on the rail support housing to fix. Only then is the fixed contact carrier 5 together with the Commutation plate through the connection lugs and the housing screwed through to the threaded plate 2.
- this second Screw 7 takes place through the V-shaped recess of the commutation plate 6, the commutation plate 6 with its upper leg 63 so far protrudes that there is already the front screw 4, which in the bore 31st the connecting lug 3 sits, covered. This way it becomes an accidental one Loosen the screw 4 by unauthorized persons or if you want to dismantle the Fixed contact carrier 5 prevented.
- the contact piece can by simply loosening the screw 7, using a Gripped screwdriver through the recess 62 of the commutation plate can be removed, the fixed contact carrier, the outer screw 4, the terminal lug 3 using the threaded plate 2 in the Fixing position holds.
