Description
Technical field
The invention belongs to chopper component parts technical field, the most just relate to one and there is Guan Bi compensation
The double breaking points movable contact system of function, improves stability and the reliability of double-breakpoint contact system action.
Background technology
Chopper is divided into primary cut-out and low-voltage circuit breaker by its range.Low-voltage circuit breaker is also known as automatically
Switch, is commonly called as " air switch " and also refers to low-voltage circuit breaker, and it is a kind of existing hand switch effect, again can
Automatically decompression, under-voltage, overload and the electrical equipment of short-circuit protection are carried out.It can be used to distribute electric energy, infrequently
Ground starts asynchronous motor, and power circuit and motor etc. are carried out protection, when they occur serious overload
Or during the fault such as short-circuit and under-voltage can automatic shutdown circuit, its function is equivalent to Fuse switch with the most deficient
The combination of thermorelay etc., and typically need not change parts after disjunction fault current, obtain
It is widely applied.
Along with constantly increasing and the needs of centralized power distribution of net capacity, electrical equipment requires its breaking capacity increasingly
Height, so current-limiting type structure of contact terminal is extensively applied in breaker of plastic casing, particularly double-breakpoint structure is disconnected
Road device, owing to arc energy is undertaken by two contacts, breaking capacity improves the most further, and it obtains in recent years
To developing the most widely；But existing product structure is in order to ensure the reliability of double contact action and steady
Qualitative, processing technique and material requirements to part contact are the highest, cause product cost to increase severely, the opposing party
Face contact after carrying out electric life test and the big short circuit current of disjunction there will be scaling loss, causes depositing between two contacts
In difference, it is impossible to synchronization action, scaling loss can be accelerated by contact serious to scaling loss when being continuing with, reduce product
Reliability.
Summary of the invention
It is an object of the invention to for existing double-breakpoint contact system, carrying out, electric life test is big with disjunction
After short circuit current, there is scaling loss in contact, it is impossible to synchronization action reduces the technological deficiency of product reliable breaking, carries
For a kind of double-breakpoint contact system with Guan Bi compensation function, there are differences between upper and lower static contact, no
When a contact surface, moving contact first contacts the contact face that stroke is close therewith, produces contact pressure, now
The counter-force producing moving contact is more than torsion or the moving contact initial pressure of moving contact spring, and moving contact swings,
Thus play the effect of differential compensation, it is ensured that and contact reliable contacts, improve the reliability of chopper disjunction.
Technical scheme
In order to realize above-mentioned technical purpose, the present invention designs a kind of double breaking points moving contact with Guan Bi compensation function
System, it includes contact base and dynamic touch panel, it is characterised in that: described dynamic touch panel passes through left torsion spring and right torsion spring
Being contained on contact base, left torsion spring and right torsion spring are attached separately in the mounting post of contact base both sides, left one end
Pushing down the left haptic element of dynamic touch panel, the other end props up the left side on contact base and props up groove, and right one end pushes down dynamic touch panel
Right haptic element, groove is propped up on the right side that the other end props up on contact base；
Described contact base upper surface is provided with boss, and boss props up dynamic touch panel.
Further, described boss height 0.7mm, the centre position between left haptic element and right haptic element.
Further, described contact base upper surface is provided with positioning convex, and positioning convex stretches into the positioning port on dynamic touch panel
In.
Further, described positioning convex is taper, and taper positioning convex props up locating notch.
Beneficial effect
The present invention provide a kind of have Guan Bi compensate function double-breakpoint contact system, when upper and lower static contact it
Between there are differences, not when a contact surface, moving contact first contacts the contact face that stroke is close therewith, produce
Contact pressure, the counter-force now produced moving contact is more than torsion or the moving contact initial pressure of moving contact spring,
Moving contact swings, thus plays the effect of differential compensation, it is ensured that contact reliable contacts, improves open circuit
The reliability of device disjunction.

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the present invention is elaborated.
Embodiment
As shown in accompanying drawing 1～7, a kind of double breaking points movable contact system with Guan Bi compensation function, it includes touching
Headstock 1 and dynamic touch panel 2, it is characterised in that: described dynamic touch panel 2 is contained in tactile by left torsion spring 3 and right torsion spring 4
On headstock 1, left torsion spring 3 and right torsion spring 4 are attached separately to the mounting post 101 of contact base 1 both sides, on 101 ',
The left haptic element 201 of dynamic touch panel 2 is pushed down in left torsion spring 3 one end, and the other end props up the left side on contact base 1 and props up groove 102,
The right haptic element 202 of dynamic touch panel 2 is pushed down in right torsion spring 4 one end, and the other end props up the right side on contact base 1 and props up groove 103；
Described contact base 1 upper surface is provided with boss 104, and boss 104 props up dynamic touch panel 2.
The described high 0.7mm of boss 104, the centre position between left haptic element 201 and right haptic element 202.
Described contact base 1 upper surface is provided with positioning convex 105, and positioning convex 105 stretches into determining on dynamic touch panel 2
In the mouth 203 of position, described positioning convex 105 is taper, and taper positioning convex 105 props up locating notch 203
Touch panel 2 is made to be installed on contact base 1.
The present invention's is originally that dynamic touch panel 2 is arranged on same contact base 1, use two torque springs with
Dynamic touch panel 2 is fixed by contact base 1 fit system, arranges the boss face of 0.7mm in contact base 1 side,
There are differences between upper and lower static contact, not at a contact surface, it is close that movable palping foot first contacts stroke therewith
Contact face, produces contact pressure, and the counter-force herein produced movable palping foot is more than the torsion of following torsion spring spring or dynamic
Contact initial pressure, movable palping foot swings, thus plays the effect of differential compensation.
