Embodiment
Fig. 1 represents an electric safety switch device 1 that motor is shielded, and is also referred to as motor protecting switch.It has that a rotating driver, one are used to be switched on or switched off circuit and shows knob 11 and the shell 12 that can be divided into three housing parts 13,14,15 that disconnects in overload or when opening circuit.Middle housing parts 14 has a cable intake 16 that has cable connecting terminal 17, shown in Fig. 3 and 4.
Fig. 2 represent 5, one links 6 of part stent can be fixed on it above.This link 6 is made of copper, and L-shaped.At this, the leg 18 towards the outside of bottom is set up the contact tap as cable connecting terminal 17.
Part stent 5 has a fixedly peg 23, and it is inserted in the corresponding groove of bottom leg 18 of link 6.
On the upper leg 21 of link 6, be provided with a join domain 19.On it with electricity be connected with mechanical system known type, be wound in heating element 22 or heater on a bimetallic spring or the bimetallic 8.This first join domain 19 fetches realization by Buchholz protection welding or plasma welding, and at this, first pad 24 is showed in Fig. 5 in more detail.25,26,27 of pads subsequently fetch by gas shielded arc welding to be finished.
One second pad 25 is on the connecting portion between heating element 22 and the bimetallic 8.By the Buchholz protection welding of second pad 25, bimetallic 8 links together each other securely with a kind of alloy that self is difficult to weld, thereby has overcome the quality problems that may cause thus.
By means of the welding of Buchholz protection welding or plasma, heating element 22 is welded on passive of bimetallic 8.The passive face of bimetallic 8 is well suited for and welds, and is to be made by the alloy that quite is difficult to weld or can't weld because have only active surface.
The bottom of bimetallic 8 and a rim lamination 28 vertical connection on a bandy tongue piece 33.
This rim lamination 28 is by forming with the lower part: transverse leg that U-shaped zone that has two parallel side leg 29,31, one couple together them 30, one are connected second canned paragraph 32 and tongue piece 33 on the leg 31 with vertically being integral, and high speed circuit breaker is fixing by side leg 29,31.
Be provided with a fixed connecting plate 35 on canned paragraph 32, it extend in the vertical blocked hole 36 that has a fixing joint tongue 37, and therefore, rim lamination 28 is fixed in the part stent 5.
Contact element 7 is configured to be parallel to canned paragraph 32, at this, trip coil 38 is connected with contact element 7 by one the 3rd pad 26 in a coil end portion, and another coil end portion is connected on canned paragraph 32 with rim lamination 28 by one the 4th pad 27.At this, flow through to galvanic areas rim lamination 28, promptly flow into bimetallic spring 8 from the 4th pad 27.
Contact element 7 partly is arranged in the rim lamination 28, at this, is provided with otch 39,40 on contact element 7 and rim lamination 28.
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 segment 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 in the end segment 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 air 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 in the shell 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 distinguished 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 fixing peg 23 and is mechanically fixedlyed connected.
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.
Part stent 5 is made by thermoplastics, and to be bonded in also be in the shell of being made by thermoset plastics 12 or on the housing parts 13, as out of phase other part stent.
Need not to use such as be threaded or clamp and similarly add be connected carry out bonding.
As in Figure 13, seeing, on shell 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 is immersed 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.Also have the 3rd group of pin 55 on rim lamination 28, to be shaped in addition.
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 12 pins 53,54,55.When therefore, just having cancelled the use thermoplastics necessary all be threaded.By this persistent fixedly connected, make the bimetallic position keep stable in simple mode.Reduce thermal stress and mechanical stress widely by use thermoplastics and 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 shell 12 in the chamber of its setting.
