Below, can more detailed explanation desirable embodiment of the present invention with reference to drawing figures.
Fig. 1 is the plane concept map of the part shown by main portion of the mesolow distribution transformer no-load tapping switch of one embodiment of the present of invention, and Fig. 2 is the side concept map of the part shown by main portion of the different mesolow distribution transformer no-load tapping switch of one embodiment of the invention.
As shown in the figure, the present invention can understand from following content: fixing support plate 100 possesses fixed contact 200, drives communication portion 300 to be moved by current collector 400, and mobile support plate 500 is the mobile supporting structures driving communication portion 300.
Fixing support plate 100 provides area and space for the fixed contact 200 arranged with the insulator of fixed-area and length, as mentioned below.
Fixed contact 200 is multiple according to carrying out arranging after the length direction isolation of fixing support plate 100, maintains the state of current collector 400 and electrical contact.
Drive communication portion 300 to balance with the fixing support plate 100 receiving the actuating force that drive source (not shown) is passed on to come and go, the actuating force impelling hereafter current collector 400 movement can be passed on.
Current collector 400 is corresponding with fixed contact 200 to be arranged to be mounted to and drives communication portion 300, and coming and going of linkage driving communication portion 300, contacts with fixed contact 200 or remove contact.
Mobile support plate 500 balances with fixing support plate 100 and arranges, and supports to drive coming and going of communication portion 300.
Thus, the invention provides the stability and the contact property that balance the following action of the mobile support plate 500 arranged with fixing support plate 100.
The present invention can be applicable to foregoing embodiments, is also applicable to following examples.
First, fixing support plate 100 is fixed insulation tapping plates 110 of the fixing length in direction as in Fig. 1 and Fig. 2.
Also have, drive communication portion 300 and fixing support plate 100 to balance to arrange, actuating force is passed on to carry out forward and inverse rotation, be combined with screw with the rifle bar 310 of the mobile support plate of support, the forward and inverse rotation of linkage rifle bar, according to the length direction back and forth movement of rifle bar, and contain more than one driver.
At this, current collector 400 is arranged on driver 320 place respectively.
At this moment, mobile support plate balances by with fixing support plate and rifle bar the bus (busbar) arranged, and the fixing support plate that a bus part extends is combined into, and contains the supporting pieces 520 supporting that the part of the rifle bar rotated rotates.
Say again, bus 510 is length direction along the projecting fixing support plate 100 of multiple fixed contact 200 in position, both sides of the edge in Fig. 3 (a) and balances setting and form, at this moment the corresponding multiple fixed contact 200 of current collector 400 comes and goes, and linkage current collector 400 carries out the driving communication portion 300 come and gone along the length direction of bus 510.
That is, can form this kind of change mechanism: contrast background technology 2, be more prone to pass on actuating force to driving communication portion 300, the movement according to current collector 400 more accurately determines position.
And, as shown in Fig. 3 (b), bus 510 is arranged at fixing support plate 100 and contiguous fixing support plate 100 intermediate equilibria, at this moment fixed contact 200 is projecting multiple at the most marginal position of the side of fixing support plate 100 and contiguous fixing support plate 100, and the corresponding multiple fixed contact 200 of current collector 400 comes and goes.
Further, current collector 400 carries out the driving communication portion 300 come and gone along the length direction of bus 510, namely link with driver 320.
The present invention is applicable to above embodiment, also certainly can be applicable to following examples: fixed contact 200 in Fig. 4, forms contact according to the current collector 400 rotated.
That is, fixing support plate 100 is exactly the fixed head 120 with fixed thickness and length and fixed-area, and fixed contact 200 is carried out arranging multiple on fixing support plate 100 with radial isolation.
Drive communication portion 300 to pass on and receive actuating force, fixing support plate 100 carries out forward and inverse rotation.
After the corresponding fixed contact 200 of current collector 400 is arranged, driving communication portion 300 is installed, and the forward and inverse rotation of linkage driving communication portion 300, contacts with fixed contact 200 or removes contact.
Guide is carried out in the rotation of move guidance portion 600 to the driving communication portion 300 be arranged on fixing support plate 100.
At this, drive communication portion 300 to be arranged on the center of fixing support plate 100, be combined in the end of rotating shaft 330 with the rotating shaft 330 passing on actuating force to carry out forward and inverse rotation, comprise the rotation rod rotating two ends centered by rotating shaft 330.
At this moment, rotate the both ends of rod 340 to carry out isolation be arranged on inside multiple fixed contact 200 with radial on fixing support plate 100.
Further, at rotation rod 340, each installs current collector 400, and move guidance portion 600 can be arranged on fixing support plate 100 and rotate on rod 340.
On the other hand, the structure in move guidance portion 600 is: move by guide rail 610 guide pin 620, guide pin 620 supports elasticity by spring 630.
Guide rail 610 is formed with closed-curve shape on fixing support plate 100, and be arranged on the inner side of multiple fixed contact 200, the center of closed curve is arranged on fixing support plate 100 center.
Guide pin 620 is combined with driving communication portion 300, moves by the formation direction of guide rail 610, simultaneously by driving the formation direction of communication portion 300 to come and go.
More in detail, on the gathering sill 341 formed along the length direction rotating rod 340 both sides, each comes and goes combination to guide pin 620, and moves by the formation direction of guide rail 610.
Spring 630 drives the guide pin 620 of communication portion 300 to push to drive the bounce effect in the outside of communication portion 300 to provide elasticity support for being combined in.
More in detail, spring 630 each be built in gathering sill 341, for by guide pin 620 from rotating shaft 330 push to rotate rod 340 side, two ends and elasticity support is provided.
Aforesaid closed curve is concatenated to form in order by the first rail portion 611 and the second rail portion 612.
First rail portion 611 forms at the setting position of multiple fixed contact 200 circular shape protruded.
One in the corresponding multiple fixed contact 200 of second rail portion 612 is formed with the position balance in the midfeather portion of contiguous fixed contact 200, forms at the central part with the interconnective fixing support plate 100 in the both ends of the first rail portion 611 circular shape protruded.
Thus, as described above, because supported by spring 630 elasticity by the guide pin 620 carrying out movement with the closed-curve shape of upper rail 610, thus make to carry out the current collector 400 of movement and fixed contact 200 abrasion each other minimize by rotating the rotation of rod 340, the implicit security accident etc. that current collector 400 causes because of contact unwanted in movement can be prevented.
It can thus be appreciated that, can understand with the mobile electric terminal taken out a little of various method facility as described above in the present invention, action stability and contact property when improving mobile, the basic fundamental thought of the mesolow distribution transformer no-load tapping switch of contact site abrasion when preventing from rotating.
Further, in the category of claims of the present invention, those of ordinary skill in the art can carry out other many distortion and application.
