Abstract
The invention discloses a guide sleeve. A plurality of isosceles trapezoid-shaped slots are uniformly formed in the side of the guide sleeve in contact with a movable conductive rod along the axial direction, the short bottom side of each isosceles trapezoid-shaped slot is located in the inner wall of the guide sleeve, and the long bottom side of each isosceles trapezoid-shaped slot is located between the inner wall and the outer wall of the guide sleeve; a plurality of disconnected clamp holes are uniformly formed in the outer wall of the guide sleeve along the circumferential direction, the clamp holes and the isosceles trapezoid-shaped slots are distributed at intervals, the guide sleeve is connected with a movable end cover plate, and a plurality of through holes matched with the clamp holes are formed in the movable end cover plate. The guide sleeve avoids the twisting of the movable conductive rod, the move of the axle center and the twisting between the guide sleeve and the movable end cover plate.
Description
Technical field
The present invention relates to electrical equipment, particularly relate to a kind of fairlead.
Background technology
Fairlead is a vitals in electronic device vacuum interrupter, for guiding the direction of motion of moving conductive rod.Moving conductive rod is by the connection of the electric current that moved up and down and shutoff, because moving conductive rod is fixedly connected with bellows, bellows twisting directly can be caused even to break if twisting occurs moving conductive rod in motion process, thus have a strong impact on the life-span of vacuum interrupter.There is following problem in current fairlead:
1, moving conductive rod does translational motion along vertical with direction of motion plane and moving conductive rod axle center there occurs movement, and this will cause moving conductive rod discontinuity to cause bellows to deform even breaking.
2, fairlead is in use connected with moved end cover plate, and does not arrange anti-wrench device between moved end cover plate and fairlead.
3, cover plate wall in moved end is thinner, can not effectively prevent from twisting therebetween with being connected according to cutting ferrule between moving conductive rod, and cutting ferrule to connect difficulty of processing larger.
4, moving conductive rod easily twists, and causes whole vacuum interrupter to be scrapped.
Summary of the invention
In order to solve the problem, the present invention proposes a kind of fairlead and both can prevent from moving conductive rod generation twisting from having can preventing moving conductive rod to be axially moved, and is provided with anti-wrench device between fairlead and moved end cover plate simultaneously.
To achieve these goals, the technical solution used in the present invention is as follows:
A kind of fairlead, the side that described fairlead contacts with moving conductive rod is evenly provided with the draw-in groove of several isosceles trapezoid shape vertically, the shorter base of the draw-in groove length of side of described isosceles trapezoid shape is positioned at the inwall of fairlead, and the longer base of the draw-in groove length of side of described isosceles trapezoid shape is between fairlead inwall and outer wall; The outer wall of described fairlead is circumferentially evenly provided with the hole clipping of several not conductings, the draw-in groove of described hole clipping and isosceles trapezoid shape distributes alternately, described fairlead is connected with moved end cover plate, and described moved end cover plate is provided with several through holes mating use with described hole clipping one by one.
The draw-in groove of described isosceles trapezoid shape runs through whole fairlead vertically.
The draw-in groove number of described isosceles trapezoid shape is preferably 4.
The number of described hole clipping is preferably 4.
Described hole clipping and described through hole are bolted to connection.
Angle between the base that the draw-in groove length of side of described isosceles trapezoid shape is longer and waist is 45 °-60 °.
Beneficial effect of the present invention is:
1, adopt isosceles trapezoid shape draw-in groove effectively to prevent in moving conductive rod motion process to twist;
2, the base that the draw-in groove length of side of isosceles trapezoid shape is shorter is positioned at the inwall of fairlead, and the longer base of the draw-in groove length of side of isosceles trapezoid shape, between fairlead inwall and outer wall, effectively prevents moving conductive rod axle center to be moved;
3, on fairlead, be provided with cartoon, by pin, fairlead and moved end cover plate fixed, effectively prevent between fairlead and moved end cover plate and twist;
4, manufacture craft is simple, and install simple, cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is moved end covering plate structure schematic diagram.
Wherein, 1, the draw-in groove of isosceles trapezoid shape; 2, the base that the draw-in groove of isosceles trapezoid shape is longer; 3, fairlead inwall; 4, fairlead outer wall; 5, moved end cover plate; 6, hole clipping; 7, through hole.
Embodiment
In order to better understand technical scheme of the present invention, below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, a kind of fairlead, the side that this fairlead contacts with moving conductive rod is evenly provided with the draw-in groove 1 of several isosceles trapezoid shape vertically, the shorter base of the draw-in groove length of side of isosceles trapezoid shape is positioned at the inwall 3 of fairlead, and the longer base 2 of the draw-in groove length of side of isosceles trapezoid shape is between fairlead inwall 3 and outer wall 4; The outer wall of fairlead is circumferentially evenly provided with the hole clipping 6 of several not conductings, and described hole clipping 6 distributes alternately with the draw-in groove of isosceles trapezoid shape.
Fig. 2 is the structural representation of moved end cover plate, and fairlead is connected with moved end cover plate 5, and described moved end cover plate is provided with several through holes 7 mating use with described hole clipping 6 one by one.
The draw-in groove of isosceles trapezoid shape runs through whole fairlead vertically.
The draw-in groove number of isosceles trapezoid shape is preferably 4.
The number of hole clipping is preferably 4.
Hole clipping and described through hole are bolted to connection.
Angle between the base that the draw-in groove length of side of isosceles trapezoid shape is longer and waist is 45 °-60 °.
During use, first the moving conductive rod mating use with the present invention is sleeved in fairlead, by moving conductive rod together with bellows-welding, draw-in groove and through-hole alignment is fixed with bolt simultaneously.The present invention adopts the draw-in groove of isosceles trapezoid shape, effectively can prevent the twisting of moving conductive rod, the shorter base of the draw-in groove length of side of isosceles trapezoid shape is positioned at the inwall of fairlead, the longer base of the draw-in groove length of side of isosceles trapezoid shape is between fairlead inwall and outer wall, the axle center of moving conductive rod effectively can be prevented to be moved, to avoid due to moving of moving conductive rod axle center and bring harmful effect.Angle between the base that the draw-in groove length of side of preferred isosceles trapezoid shape is longer and waist is 45 °-60 °, because practice shows that the torque forces suffered by moving conductive rod is obviously greater than the power caused on the moving direction of axle center, just have the angle of this scope can make the torque forces suffered by fairlead and cause the power of axle center movement to realize one to weigh preferably, final realization can prevent the twisting of moving conductive rod from the axle center of moving conductive rod can be prevented again to be moved.
By reference to the accompanying drawings the specific embodiment of the present invention is described although above-mentioned; but not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection scope of the present invention.
