Embodiment
In Figure 1A-1B and 2A-2B; Can see two opposed surface 1a, the 1b of contact mat 1; Be designed to be assembled on fixed electrode 11 or the movable electrode 12; In the vacuum bubbles (not shown), to obtain fixed contact or moving contact, be designed to be integrated in the circuit breaker that uses the radial field technology of breaking in vacuum bubbles described in the embodiment of this description.This contact mat 1 at its two opposed surface 1a, 1b is last is identical; And comprise four quadrature radial slots 2,3,4 and 5; Each otch disposes around the central axis X of contact mat equally spacedly; Said otch 2,3,4 and 5 forms four wings 6,7,8 and 9 that all point to equidirectional R, and therefore said contact mat disposes with the mirror image mode.Therefore this contact mat 1 can likewise use in a side or opposite side.Shown in Fig. 2 A-2B, two contact mats 1,10 shown in Figure 1A-1B are designed to be fixed on their corresponding fixed electrodes 11, the movable electrode 12 through hard solder.According to the utility model; Above-mentioned vacuum bubbles comprises error prevention device; These devices comprise outstanding element 13,14 for each contact mat 1,10; Said outstanding element is arranged on the free end of each fixed electrode 11, movable electrode 12, is designed to insert in the opening with respective shapes 15,16 of the center that roughly is arranged on the corresponding contact pad.According to this specific embodiment; Also like Fig. 5,8,9 and 11, shown in 12, the outstanding element 13,14 of fixed electrode 11 and movable electrode 12 and be arranged on respective openings 15,16 on the contact mat 1,10 is the part of asymmetric disk along the cross section that is parallel to the plane on contact mat plane shape.Therefore, for the outstanding precalculated position of element on electrode, contact mat can not use in a side or opposite side on identical contact, but can on fixed contact or moving contact, use.According to present embodiment; Error prevention device is arranged such that on electrode the quadrature radial slot 2,3,4,5 of one of them contact mat 1 is positioned to face the quadrature radial slot 17,18,19,20 of another contact mat 10; Two contact mats 1,10 dispose with the mirror image mode; Part between the otch limits wing, and the wing of one of contact mat points to the direction of rotation identical like the wing of another contact mat.The relative position of two contact mats 1,10 is confirmed in the outstanding position of element 13,14 on fixed electrode 11, movable electrode 12 therefore.
Though what note that embodiment description described above is the contact mat that the utility model is applied to comprise the equidistance otch, this mistake proofing operation also can be applicable to have the contact mat of the otch of configuration brokenly.
In Fig. 3 A-3B, be labeled as 21 contact mat and be designed to be used in a kind of like this vacuum bubbles, this vacuum bubbles is designed to be integrated in the circuit breaker that uses the axial magnetic field technology of breaking.According to present embodiment, two opposed surface the 22, the 23rd of this contact mat, different, therefore this contact mat can not indistinguishably use at a side or the opposite side of identical contact.Yet this contact mat all is identical no matter be designed to be used as fixed contact or be used as moving contact.In fact can realize limiting contact mat according to the error prevention device of the utility model is as fixed contact or as moving contact.According to present embodiment, otch the 24,25, the 26th, the equidistant radial otch, and quantity is three.Error prevention device obtains with the mode identical with previous embodiment, and can make two contact mats 21,27 be located such that relative to each other for example the radial slot 24,25,26 of a contact mat 21 is configured to the radial slot 28,29,30 in the face of another contact mat 27.Note that and can imagine another embodiment, wherein the otch of one of contact mat will be with respect to the otch angle presentation skew of another contact mat, and it is favourable that this skew is included between 0 to 45 °.
Therefore; In all these embodiment; The assembling of contact mat on electrode is performed such: the outstanding element that at first will be arranged on the electrode is inserted in the respective openings that is arranged in the contact mat, then in the hard solder zone of outstanding element location with contact mat hard solder to corresponding electrode.
Therefore; Be designed for using in the vacuum bubbles of the technological circuit breaker of radial magnetic field for being used in; The utility model can be realized being provided with can be as the single contact mat of fixed contact or moving contact; Said contact can distinguished when assembling according to the error prevention device of the utility model, and said device is integrated in contact and the support thereof.
In this particular case, can make the wing sensing of one of contact mat and the shape wing equidirectional, that be called as " mirror image " shape of another contact mat, in fact can obtain through rotating (turning) each contact mat simply.
Please note; Though in these embodiment; Two contact mats are alloted through error prevention device becomes to make the cut sides of a contact mat to the otch of another contact; But the also configurable one-tenth of these two contact mats makes the otch of a contact mat be the skew of angle ground with respect to the otch of another contact mat, and this angular deflection can be adopted all possible value.
Therefore can realize only using single contact in some cases according to the electric switch equipment of the utility model, distinguish when fail-safe system in contact and the support thereof is assembled by means of being integrated in as fixed contact or moving contact.
Therefore, for example, for the vacuum bubbles of the circuit breaker that uses the radial magnetic field technology, image shape obtains through rotating one of two contacts, and the assembling on fixing or movable electrode obtains by means of fail-safe system.
For the vacuum bubbles of the circuit breaker that uses the axial magnetic field technology, contact carries out with respect to alloting through fail-safe system of its support, and the assembling on fixing or movable electrode obtains by means of fail-safe system.
Therefore the utility model can be realized using single contact mat, makes the risk minimization of assembly defect.
Thereby this has eliminated the necessity of carrying out visual inspection, and visual inspection can not filter out all, and has up to this point caused expensive special examined, and scraps the finished product vacuum bubbles of incorrect assembling.
Therefore the utility model can be realized minimizing parts benchmark (parts references) and the quantity of the fabrication tool that is associated, thereby obtains bigger output effect.
Inspection is simplified, and wrong risk is reduced.
The utility model be not limited to naturally describe and illustrated embodiment, they just as an example purpose provide.
On the contrary, the utility model may extend into all technical equivalents schemes that comprise described device and combination thereof, as long as they are to carry out according to the spirit of the utility model.
