Embodiment
are as shown in Figure 1; Adopt the double break point lv contactor structure of contact terminal of soft connection device, it comprises the first fixed contact unit 101, the second fixed contact unit 102, the first moving contact unit 201, the second moving contact unit 202, elastic mechanism 4, linkage 5, be flexible coupling 6 and insulating support 7; The said first moving contact unit 201 and the second moving contact unit 202 6 are fixedly connected through being flexible coupling; Said elastic mechanism 4 is fixed between the first moving contact unit 201 and the second moving contact unit 202; Said insulating support 7 is fixedly connected through linkage 5 and elastic mechanism 4.
the utility model elastic mechanism 4 can adopt the springs structure.
referring to Fig. 3, the utility model is respectively equipped with protruding 12 in the end of said insulating support 7; On the said first moving contact unit 201 and the second moving contact unit 202, be provided with draw-in groove 9 with above-mentioned protruding 12 correspondence positions; The end of said insulating support 7 is through the protruding 12 and first moving contact unit 201 and the second fixedly clamping of moving contact unit 202.
the utility model is respectively equipped with groove 10 on the said first moving contact unit 201 and the second moving contact unit 202; Said elastic mechanism 4 and groove 10 clampings.
the utility model is fixed with lever 13 in the upper end of said linkage 5; Said elastic mechanism 4 and fixedly clamping of lever 13.
The front end of the said first moving contact unit 201 of
the utility model and the second moving contact unit 202 adopts and upwarps structure.
The said first fixed contact unit 101 of
the utility model and the second fixed contact unit 102 can adopt U type structure.
There are differential seat angle in the said first fixed contact unit 101 of
the utility model and the first moving contact unit 201 and the second fixed contact unit 102 and the second moving contact unit 202 in the elevation angle of disjunction position.
the utility model mainly solves contactor after breaking current repeatedly; Cause the problem that break performance descends by the contact surface wearing and tearing; Providing a kind of is the novel low-voltage alternating-current probe of contactor structure of innovative point by soft connection device and springs, can balance contact both sides pressure, reach effectively closely contact between the contact; Realize the contact surface self-cleaning function simultaneously, improve the contact purpose in useful life thereby reach.
the utility model by the first fixed contact unit 101, the second fixed contact unit 102, the first moving contact unit 201, the second moving contact unit 202, springs 4, linkage 5, be flexible coupling 6 and insulating support 7 constitute.Dynamic and static contact has differential seat angle at the elevation angle, disjunction position in the first fixed contact unit 101, the second fixed contact unit 102, the first moving contact unit 201, the second moving contact unit 202, closely contacts in make position.In closing course, dynamic and static contact has sliding friction, and this slide relative had both helped to clean the contact surface oxide, can make between the contact again to combine more closely, helps to reduce contact resistance and improves contact conductivity.
are referring to Fig. 2; The said first moving contact unit 201 of the utility model, the second moving contact unit 202 are stuck in the draw-in groove 9 of insulating support 7; First moving contact unit 201, both sides and the second moving contact unit, 202 ends are separately fixed at 6 the two ends of being flexible coupling; After dynamic and static contact closure, by the first fixed contact unit 101, the second fixed contact unit 102, the first moving contact unit 201, the second moving contact unit 202 and be flexible coupling and 6 form galvanic circles jointly.In the contact closure process, be flexible coupling and roll over certain angle on 6.
The said sheet bullet of
the utility model 4 lower ends are stuck in the terminal groove 10 in the first moving contact unit 201, both sides and the second moving contact unit 202, and the upper end is stuck in the lever 13 times of linkage 7, forms interlinked mechanism.In the contact closure process; Linkage 7 compression springs 4; Springs 4 can the active balance pressure at both sides; Promote the first moving contact unit 201 and the second moving contact unit 202 moves downward,, reach the good effect of contact both sides isostasy until closely contacting with the first fixed contact unit 101 and the second fixed contact unit 102.
the utility model first moving contact unit 201, said both sides and the second moving contact unit, 202 front ends upwarp respectively; As arc leading angle; The first fixed contact unit 101 and the second fixed contact unit 102 are set to U type structure and fix through bolt and contactor shell, and when breaking arc, dynamic and static contact acting in conjunction produces and makes the outwards electric power of motion of electric arc; Blow-out on arc leading angle ensures the contact life-span.
In
instance; Because the first fixed contact unit 101 and the first moving contact unit 201 and the second fixed contact unit 102 and the second moving contact unit 202; There is differential seat angle in the elevation angle in the disjunction position; From the process that touches complete closure, slide relative between the contact contact-making surface, clean surface salient point and oxide.Springs 4 can balance both sides moving contact pressure, guarantees that contact force is even between the double break point.Springs 4 be flexible coupling 6 setting, make above-mentioned two functions be able to good realization.After the complete closure of contact, electric current flows into from an end fixed contact, through moving contact, be flexible coupling, moving contact, flow out from other end fixed contact at last, realize the conducting in whole loop.
because the elevation angle, disjunction position is different, when dynamic and static contact was in the close position, moving contact received the terminal perk of fixed contact effect, and being flexible coupling produces bending in the part that links to each other with moving contact, and this angle is in allowed band.
The above is merely the preferred embodiment of the utility model
, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the utility model.
