Embodiment
The differential switch D that comprises pedestal 1 and lid (not shown) that is contained in housing shown in the drawings, described housing has held in known mode like this: the back shaft 2 of the moving contact 3 of support unit; Static contact 4; Side of wire was terminal and load side terminal 5 and 6; With opened/closed or axle operating mechanism 7; Toroidal core 8; Leading body 9; Contact holddown spring 10; Open spring 11 with the contact.
Disconnect module 13 and design to support the assembly that has comprised the axle 2 that is called the current collector back shaft, described current collector 3 utilizes braid 18 to be connected to the contact web 19 of corresponding load side terminal 6.This module supports static contact 4 in addition, and it is welded to an end of leading body 9, and its another end 20 is connected by welding to the contact web 21 of the side of wire was terminal 5 of corresponding unit.This component design is for disconnecting on module 13 by axle 2 being inserted be arranged in the U-shaped depression that is provided in module, and insert respectively in two holes 26,25 that are provided at disconnection module 13 and with respect to the rotary components of described module 13 insertion axles 2 end 23,24 of the axle 2 by will support current collector 3.
It should be noted that, arc slideway 13 utilizes part to be provided to disconnect on module 13 and the sliding system 27 of part on pedestal, 28 and be fixed to pedestal.
Can move owing to disconnecting module, arc slide track materials will advantageously have the technical characteristic that is different from case material, and base and cover will can not participate in disconnecting electric arc.
That the performance of arc slideway therefore is no longer dependent on technical performance and pedestal or lid about the balance between the other function of for example aesthetic appearance of material, material cost, terminal shell or the arrangement of some equipment.
The performance of switch will be better than the performance of present modular unit thus, and precious materials is preserved for arc slideway.
Slideway is because module is monolithic and because the contact back shaft makes it possible to have darker slideway relative to each other and airtight with respect to pedestal.
Creepage distance is kept, because there is not shorter creepage distance between arc slideway, this is to be monolithic owing to not sealing and disconnecting module between arc slideway.The solution that adopts arc slideway to be closed by shaft seal makes other creepage distance to extend by the degree of depth that increases arc slideway, and does not have any additional stress.
According to the embodiment that illustrates in accompanying drawing, contact back shaft, current collector, static contact, contact holddown spring and open spring and be integrated in the removable monoblock modules that is formed by arc slideway.
This makes the single part of position reference of contact back shaft, current collector and static contact carry out.
The location dispersion is minimized thus and the installation of module in pedestal is very easy to.
Contact alignment is improved and therefore making and turn-off characteristic be better than the characteristic of other modular unit.
There are not the contact and the spring that are positioned on pedestal when installing.
Do not exist yet any necessity with provide screw be used for stuck-module to the pedestal with the compression contacts holddown spring.This make toroidal core and coil be assemblied in outside pedestal disconnect on module rather than in pedestal.
Be assemblied in pedestal and can carry out at single operation rather than in two operations being assemblied in the annular magnetite and the coil that disconnect on module.
And the coil and the contact web that are disposed at toroidal core are welded to static contact, and it is positioned on the disconnection module in the pedestal outside.
This makes and does not have the scolder bump and fall in pedestal, and does not therefore have internal contamination and so do not have a risk that reduces inner creepage distance when welding is electrically connected to.
And the layout of static contact welding band makes welding to carry out when arc slideway is directed toward the top of unit close to the bottom that disconnects module as much as possible, and arc slideway is in the outside of pedestal at this moment.
The scolder bump can not fallen into arc slideway thus.
When being electrically connected to, welding do not have thus the pollution for arc slideway, and therefore without reducing the risk of inside to the creepage distance of arc slideway.
The sub-component that consists of thus can be common to some different examples, particularly for the terminal with different size or type.Pedestal also can have different colors, different material or different shapes.
With regard to the different differential switch of their formation, switch, cut-out switch, with or without remote control ... function, pedestal also can be different.
Therefore pedestal does not reconstruct the obstruction for manual or automatic build-up member.Built-in function can be revised and need not change pedestal, and pedestal can be revised and can not change built-in function.
The configuration of function can be flexibly, need not change built-in function.The difference that can delay time.The assembling of terminal can be different, and passage or flexible terminal have different pedestals.The outward appearance of housing can be changed and need not be revised built-in function.
Function can be tested outside pedestal, and this has been avoided defective sub-component to be placed on the final products line, has reduced thus cost.
The sub-component variable can be stored to give the flexibility in production.
