Background technology
Circuit breaker mainly adopts the Cu-Cr alloy material with the vacuum arc-extinguishing chamber contact material, and Cr and oxygen affinity are strong, very easily oxidation, and in a vacuum can not decomposition-reduction after the oxidation.The arc control device of the vertical magnetic structure of cup-shaped need first assembling and solder contacts parts, the Cu-Cr alloy contact is easy to oxidation when producing contact component, and contact component after producing in the process of homogeneous tube assembling, the contact dish also can oxidation and pollution, need to again carry out purified treatment, and the contact component structure relative complex that assembles and sealing, purified treatment is difficulty.What wherein have the greatest impact is the surface state of putting the Cu-Cr alloy material contact dish of contact surface as electricity, addressing the above problem one of adoptable mode is to refill to join the good Cu-Cr alloy contact dish of purified treatment when homogeneous tube is assembled, and soldering envelope is lined up homogeneous tube.And do not have position limiting structure between the planar structure contact dish of employing, contact pallet, the contact cup at present, can rotate around axis each other before the soldering.Arc control device adopt the one-step seal-exhaust mode, when homogeneous tube is assembled, refill and join the contact dish, because behind the assembling shell, again visual adjustment of contact, before the soldering sealing-in, each parts of the homogeneous tube that assembles are loose fitting together, and subsequent parts is when assembling, owing to need circumferentially to adjust, thereby easily cause contact dish and contact pallet fluting to misplace and can not adopt; Production efficiency is low, and rate of finished products is not high, and production cost is high.
The utility model content
The utility model aims to provide the vertical self-align contact of magnetic of a kind of vacuum interrupter cup-shaped, and production, easy to assembly is improved the quality of products, and improves rate of finished products and production efficiency, reduces cost.
For achieving the above object, the utility model is realized by the following technical solutions:
The disclosed vacuum interrupter cup-shaped of the utility model is indulged the self-align contact of magnetic, comprises contact dish, contact pallet, supporting seat, contact cup; Described supporting seat is supported between contact cup and the contact pallet, contact pallet, supporting seat, contact cup three form a closed housing, described contact dish is connected on the outer surface of contact pallet, contact dish inner surface is provided with tenon, contact dish fluting, contact pallet outer surface is provided with the groove suitable with tenon, contact dish fluting, pallet fluting, and described contact pallet is provided with the suitable flange of outer rim of medial surface and contact dish.
Preferably, the connected mode of described contact dish and contact pallet is soldering.
Further, described tenon is arranged on contact disk center position, and described contact dish fluting has a plurality of, and radially distributes.
Preferably, described contact dish fluting is even number and equal angles distribution, and tenon is rectangle, and groove is the round end slotted hole.
Preferably, described contact dish fluting is odd number, and tenon is trapezoidal.
The utility model has realized that the vertical magnetic contact of vacuum interrupter cup-shaped just carries out core part---the assembling of contact dish of arc control device when homogeneous tube is assembled, the hidden danger of quality of having avoided the oxidation stain of contact dish to cause, step and the cost of contact component purified treatment have been reduced, improved product quality, improve rate of finished products and production efficiency, reduce cost.

Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model is further elaborated.
Shown in Fig. 1,2,3,5, the disclosed vacuum interrupter cup-shaped of the utility model is indulged the self-align contact of magnetic, comprises contact dish 1, contact pallet 2, supporting seat 3, contact cup 4; Supporting seat 3 is supported between contact cup 4 and the contact pallet 2, contact pallet 2, supporting seat 3, contact cup 4 threes form a closed housing, described contact dish 1 is connected on the outer surface of contact pallet 2, contact dish 1 inner surface is provided with tenon 11, contact dish fluting 12, contact pallet 2 outer surfaces are provided with and tenon 11, contact dish slot 12 suitable grooves 21, pallet fluting 22, the contact pallet 2 outer suitable flanges 23 of outer rim that are provided with medial surface and contact dish 1.
Preferably, contact dish 1 is soldering with the connected mode of contact pallet 2.
As shown in Figure 4, further, tenon 11 is arranged on contact dish 1 center, and contact dish fluting 12 has a plurality of, and radially distributes.
Preferably, contact dish fluting 12 is that even number and equal angles distribute, and tenon 11 is rectangle, and groove 21 is the round end slotted hole; So that contact dish 1 can be installed with respect to contact pallet 2 in 180 ° of commutations, reduce labor intensity.
