Abstract
The invention discloses a connection mode for a main wire connecting terminal and a conductive aluminum arm of a novel isolating switch. In the connection mode, a main shaft, a fixed substrate, a wire connecting terminal and a watchband contact finger are involved, wherein the fixed substrate is connected with the conductive aluminum arm; the main shaft is arranged on the fixed substrate in a rotating manner through the watchband contact finger; the upper end of the main shaft is connected with the wire connecting terminal; and sealing sleeves are arranged at intersections between the upper part as well as the lower part of the fixed substrate and the main shaft. By the connection mode, the problem that soft connection of the isolating switch is not applicable to high-current isolating switches can be solved; furthermore, the connection mode is simple in design, is rational and is particularly applicable to the high-current isolating switches.
Description
Technical field
The present invention relates to the isolating switch technical field, specifically belong to a kind of connected mode of main electrical scheme terminal and conductive aluminum arm of novel isolating switch.
Background technology
At present; The fixedly contact forms that are flexible coupling that adopt between the main electrical scheme terminal that cut-offs both at home and abroad the formula isolating switch in the middle of the twin columns and the conductive aluminum arm more; But there is following deficiency in this kind structure: do not have special sealing device owing to be flexible coupling; The long-term back dust that uses is prone to get into; Make contact resistance become big, be prone to heating; The employing fixed form that is flexible coupling, mostly its corner is 90 °, can not realize that 360 ° are freely rotated, and is prone to lead-in wire is produced the strength of pullling, and the main electrical scheme terminal is formed with lead-in wire impact; Because sectional area can not be excessive, makes the fixed form that is flexible coupling be difficult to be applicable in the isolating switch of big electric current.
Summary of the invention
The connected mode that the purpose of this invention is to provide a kind of main electrical scheme terminal and conductive aluminum arm of novel isolating switch; Having solved isolating switch is flexible coupling and is not suitable for the problem of heavy current disconnecting switches; Simplicity of design, connected mode is reasonable, is specially adapted in the isolating switch of big electric current.
The technical scheme that the present invention adopts is following:
A kind of main electrical scheme terminal of novel isolating switch and the connected mode of conductive aluminum arm; Comprise main shaft, fixed pedestal, binding post and watchband fingertip; Described fixed pedestal is connected with the conductive aluminum arm; Main shaft rotates through the watchband fingertip and is installed on fixed pedestal; The main shaft upper end is connected with binding post, and fixed pedestal is upper and lower to be provided with sealing shroud with the main shaft intersection.
Be provided with the O RunddichtringO in the sealing shroud of described upper end, the lower end sealing shroud has circlip, and O RunddichtringO and circlip all are fixed on the main shaft.
Described main shaft is with sealing shroud bottom.
Compared with the prior art, beneficial effect of the present invention is following:
Employing watch band contact of the present invention refers to for being flexible coupling, and fixed pedestal is connected with the conductive aluminum arm, and the wiring main terminal is connected with main shaft, and main shaft is connected with fixed pedestal through the watchband fingertip.Owing to adopt hermetic structure, avoided the entering of dust and the flushing of rainwater, guaranteed the stable of contact resistance, can realize long-term operation; Because main shaft and fixed pedestal can be realized 360 ° of rotations, avoid the impact of main electrical scheme terminal and lead-in wire and pull; Because every watchband fingertip of most producers can possess " the energising ability of 50A and the dynamic current ability of 0.5KA "; Article two, 47 watchband fingertip can be realized; Electric current=4700A, dynamic current=47KA so watchband fingertip are specially adapted to the isolating switch of big electric current.
