Contact element 7 partly is arranged in the rim lamination 28, at this, is provided with on contact element 7 and rim lamination 28 and leaves a blank 39,40.
Be provided with first section 41 of abutting on the part stent on contact element 7, offered a groove 42 to it, the latter acts in the supporting zone 43 of part stent.
Below first section 41 and then one second section 44, it forms in the zone 45 with being convex, and terminates in the end segments 46 that the below disposed of part stent 5.This section is set up with identical direction with the bottom leg 18 of link 6.
In zone 45 and around the end segments 46, assembled in advance has a line of rabbet joint motor 47 on part stent 5.
Be provided with two en plaque zones 49 on part stent 5, the gas in the switch gear room of their prevention switching devices enters among the areas of disconnection.
By the rotation of carrying out along the direction of arrow A shown in Fig. 2 round axis X, contact feet 7 is transferred in the part stent 5 of supporting zone 43 back and goes.
Shown in Figure 11 and 12, fixedly nose protruding 3 passes the pilot hole 48 on the housing 12, extend in the holding tank 2 on the part stent 5.
Flow into the electric current in the parts that are arranged on the part stent 5, flow to first pad 24 from the bottom leg of link 6, then flow in the heating element 22 up to second pad 25, then enter in the rim lamination 28 up to the 4th pad 27 places by bimetallic 8, then flow into and disconnect in the coil 38, then flow in the contact element 7 up to the 3rd pad 26.
Link 6 is mechanically fixedlyed connected respectively at its supporting zone 43 with part stent 5 with part stent 5 and contact element 7 by fixed connecting plate 35 with part stent 5, rim lamination 28 by gim peg 23.
Heating element 22 and trip coil are fixed by pad 24,25 or 26,27, in this way, all parts stably are fixed on the part stent 5.
Need not to use such as be threaded or clamp and similarly add be connected carry out bonding.
As in Figure 13, seeing, on housing 12, have bonding groove 51,52, in them, be filled with the bonding agent of about 0.010g.The pin 53,54 of breaking units immerses in the bonding groove.They are bonded in the there.
First group of pin 53 is formed separately on rim lamination 28, and second group of pin 54 forms on the link 6.
By bonding only be the metal continuation of lamination, here be exactly to sell 53,54. Pin 53,54 is three-dimensional and distributes, thereby guarantees good fixed effect.Amount to totally 9 pins 53,54.Therefore, just cancelled necessary in other cases all be threaded.By this persistent fixedly connected, make the bimetallic position keep stable in better simply mode.Reduce thermal stress and mechanical stress widely by the use adhering method, and guaranteed thermal stability and shape stability.
As shown in figure 15, among the housing parts 14 in the middle of breaking units is integrated in.
The part stent of assembled in advance is pushed in the housing 12 in the chamber of its setting.
Line of rabbet joint motor 47 is parts of being made by iron core or iron plate, and it plays the effect of reinforcement by this way to magnetic field, makes the contact bridge circuit open quickly.Line of rabbet joint motor 47 is U-shapeds.
