Abstract
A kind of high energy contact device, comprise fork, moving contact, fixed contact, fixed contact, moving contact, it is characterized in that moving contact and fork realize fork by articulated manner can rotate freely, moving contact, fixed contact are respectively planar contacts, due to the degree of freedom that fork and moving contact exist, sound contact can be made farthest to fit, more reliable and more stable.This application of installation, in circuit breaker, contactor, relay, has higher tolerance instantaneous large-current impact capacity, extends product useful life.
Description
Technical field
The utility model relates to the interior contact device of a kind of circuit breaker, contactor etc., provides a kind of contact point that can tolerate immediate current impact and high energy power current.
Background technology
In power transmission and distribution and circuit protection field, a large amount of device that use sky is opened, contactor, relay etc. have breaking capacity, in the middle of this kind of device, all can't do without contact component, its quality directly affects the various aspects of performance of whole device.The contact device of current most electric equipment is all swing arm structure, this structure is applied in the occasion of point cantact or linear contact lay usually, face is contacted, swing arm structure is due to self-characteristic, be difficult to allow contact point realize the contact of reliable face, in time having big current process, there being the place in gap to beat arc, components and parts performance and life-span can be had a strong impact on.
Summary of the invention
The utility model object is to provide a kind of high energy contact device, the reliable binding face making contact provide maximum, has and bears more greatly instantaneous large-current or power current impact capacity.
The technical solution of the utility model is: comprise fork, moving contact, fixed contact, fixed contact, moving contact, moving contact is welded on moving contact, fixed contact is welded on fixed contact, fork: be arranged on body fuselage or other parts, can rotate around it, moving contact and fork are linked together by articulated manner, moving contact can rotate around fork, moving contact, fixed contact are respectively planar contacts, due to the degree of freedom existed between moving contact and fork, can make the maximum area laminating of sound contact.
Feature of the present utility model and advantage:
Because moving contact and fork can relatively rotate, can adapt to voluntarily according to the angle of contact in sound contact laminating process, ensure the maximum fitting area of contact, there is the ability of bearing instantaneous large-current and impacting.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. fork, 2. moving contact, 3. fixed contact, 4. fixed contact, 5. moving contact.
Embodiment
A kind of high energy contact device as shown in Figure 1, comprise fork, moving contact, fixed contact, fixed contact, moving contact, moving contact is welded on moving contact, fixed contact is welded on fixed contact, fork is arranged on body fuselage or other parts, can rotate around it, moving contact and fork are linked together by articulated manner, moving contact can rotate around fork, moving contact, fixed contact is respectively planar contacts, because moving contact and fork exist a rotary freedom, make moving contact can adapt to the plane error of fixed contact existence voluntarily, when fork rotates counterclockwise, fitted in sound contact, reach the most reliable maximum fitting area, there is provided stable and guide passage smoothly for big current flows through contact.
