具の中に挿入できるからである。When the thread consists of a through-threaded hole in the leg of the arc guide plate, auxiliary threaded parts, in particular auxiliary snap-on nuts, are not required. This is particularly possible since no holding function is required of the conductor connection bolt in the appliance. The free end of the short leg of the contact is insulated in order to, on the one hand, guarantee a precise positioning of the free end of the contact on the arc guide plate and, on the other hand, to be able to operate with relatively thin contacts. Advantageously, it can be pushed up onto the protrusion of the part. It is particularly advantageous if the free end rests with an initial tension on the protrusion of the insulating part. This is because in this case, even when the temperature of the contact rises, the positioning of the arc guide plate is maintained. It is further advantageous if the fixed contact is hooked into the insulating part so that the conductor connection bolt can be loosened and the instrument can be supplied. In order to guarantee an absolutely firm fixation of the contact even for relatively large capacity switchgear, it is advantageous if the bends of the covered legs of the arc guide plate are inserted into the grooves of the insulating part. It is. For machining of the switchgear, it is advantageous if the insulating part supports the stationary contacts of all poles of the switchgear. This is because the insulating part with all the contacts can be produced in advance in large quantities and inserted into the switching device.

はふさがれている）を有している。Connected to this, an arc-extinguishing plate device 6 is placed in the lower part l. The movable contact 7 is held in a contact support 8;
It is pushed towards the fixed contact 4 via the spring 9. The opening/closing latch mechanism that moves the contact support 8 and the tripping device that acts on the opening/closing latch mechanism are not shown in this drawing. It is held in the case by form-fitting by covering it with. Three chambers 10 are provided in the insulating part 3, each housing a fixed contact 4. Grooves 12 are cut into the side walls ll of these chambers, into which the fixed contacts 4 can be inserted in the direction of the arrow 13. For this reason, the base portion 14 of the contact is configured to be wider than the portion supporting the contact chip 15. Contact chip 15
The shorter leg 16 supporting the insulating part rests under prestress on the protrusion 17 of the insulating part. In order to facilitate the raising of the free end 18 of the shorter leg 16 onto the protrusion 17 of the insulating part, this protrusion has an inclined surface. The base part 14 forming the longer leg of the U-shaped stationary contact 4 is provided with a latching projection 19, so that the stationary contact 4 can be latched in the inserted position. Before inserting the fixed contact 4, in the direction of the arrow 20, a U-shaped arc guide plate 5 is inserted into a corresponding cavity 21 of the insulating part 3;
Moreover, the widened portions 22 facing each other come into contact with the crosspiece 23 that projects into the chamber from the side. One leg 24 of the arc guide plate 5 is provided with a bend 25 which engages in the groove 26 by pushing the arc guide plate in the direction of the arrow 13. A projection of an insulating part (not shown) cooperating with the end of the widening 22 prevents a return movement of the arc guide plate after insertion. There are two through screw holes in the arc guide plate.
7 is provided, and this through screw hole is used for screwing in the conductor connection bolt 28. After the fixed contact is in the latching position, the conductor connection bolt 28 is guided through the hole 29 in the base part 14 of the fixed contact. Due to the groove guidance in the insulating part 3 and the latching by the latching projections 19, the arc guide plate 5 and also the fixed contact 4 can be moved to the position shown in FIG. is maintained. The insulating part 3 can be inserted into the lower part 1 as a whole. The partition wall 30 of the lid part 2 engages in the groove 31 of the insulating part 3, so that a plurality of mutually delimited isolation chambers is created. A funnel-shaped inlet 32 is provided in the lid part 2 for introducing the connecting conductor. Furthermore, the lid part 2 has an opening 33 (closed in the figure) through which the conductor connection bolt 28 can be operated.
