Abstract
The invention discloses a kind of insulating pull rod for breaker, including full skirt, described full skirt be respectively arranged at two ends with cylinder lever connecting rod I and cylinder lever connecting rod II, in described cylinder lever connecting rod I and cylinder lever connecting rod II, at least one is connected with the end employing elastic construction of full skirt.The insulating pull rod for breaker of the present invention, when using elastic connection structure to buffer divide-shut brake, the impulsive force of contact, can effectively reduce the spring even eliminating contact, improve the break performance of chopper.
Description
Technical field
The present invention relates to primary cut-out accessory technical field, be specifically related to a kind of insulating pull rod for breaker.
Background technology
The spring of contact during circuit-breaker switching on-off, has a strong impact on the break performance of chopper, and affects circuit-breaker switching on-off spring
Factor mainly has: the rigidity of the quality of moving component, speed, contact pressure and insulated tension pole.Currently used insulated tension pole
Generally rigidity, moment and the rigidly connected contact of insulated tension pole at divide-shut brake can produce spring by a relatively large margin, have a strong impact on
The break performance of chopper.
Summary of the invention
It is an object of the invention to for above-mentioned existing issue, it is provided that one produces when contact of breaker divide-shut brake can be reduced or eliminated
The insulating pull rod for breaker of spring.
The technical solution used in the present invention is: a kind of insulating pull rod for breaker, including full skirt, being respectively arranged at two ends with of described full skirt
Cylinder lever connecting rod I and cylinder lever connecting rod II, in described cylinder lever connecting rod I and cylinder lever connecting rod II, at least one uses elasticity with the end of full skirt
Structure connects.After using elastic construction to connect, impulsive force during divide-shut brake can be buffered, reduce and even eliminate spring.
Described full skirt one end is fixing with cylinder lever connecting rod I to be connected, and the other end of full skirt is provided with connecting hole, described cylinder lever connecting rod II end
It is slidably mounted in connecting hole, between the end of the bottom of connecting hole and cylinder lever connecting rod II, is provided with disc spring, the peristome of connecting hole
Being provided with for by spacing for cylinder lever connecting rod II fixture in connecting hole, disc spring is pressed in the end of connecting hole by the end of cylinder lever connecting rod II
Portion.
The diameter of the described cylinder lever connecting rod II part in connecting hole, more than the part outside connecting hole, sets in the middle of described fixture
Having the through hole partially passed through for cylinder lever connecting rod II path, be provided with female thread inside the peristome of connecting hole, the outer wall of fixture is provided with
With the external screw thread of the screw-internal thread fit of connecting hole, fixture is enclosed within cylinder lever connecting rod II and is threadedly secured to the opening of connecting hole
Portion.
The invention has the beneficial effects as follows: the insulating pull rod for breaker of the present invention, use elastic connection structure to touch when buffering divide-shut brake
The impulsive force of head, can effectively reduce the spring even eliminating contact, improve the break performance of chopper.
Accompanying drawing explanation
Fig. 1 is the main structure schematic diagram of the present invention；
Shown in figure: 1, full skirt, 2, cylinder lever connecting rod I, 3, cylinder lever connecting rod II, 4, fixture, 5, disc spring.

Footpath, more than the part outside connecting hole, is provided with disc spring 5 between the end of the bottom of connecting hole and cylinder lever connecting rod II 3, connects
The peristome in hole is provided with and is provided with for connecting in the middle of by spacing for cylinder lever connecting rod II 3 fixture 4 in connecting hole, fixture 4
The through hole that pull bar II 3 path partially passes through, is provided with female thread inside the peristome of connecting hole, the outer wall of fixture 4 is provided with and connects
Connecing the external screw thread of the screw-internal thread fit in hole, fixture 4 is enclosed within cylinder lever connecting rod II 3 and is threadedly secured to the opening of connecting hole
Portion, now the enlarged diameter section card of cylinder lever connecting rod II 3 is pressed in connecting hole by fixture 4, and disc spring 5 is pressed in connecting hole by its end
Bottom.
Although the detailed description of the invention of the present invention is described by the above-mentioned accompanying drawing that combines, but not limit to scope
System, one of ordinary skill in the art should be understood that on the basis of technical scheme, and those skilled in the art need not pay
Go out various amendments or deformation that creative work can make still within protection scope of the present invention.
