Description
Technical field
The utility model is related to a kind of closed type contactor, more particularly to a kind of closed type contactor with arc leading angle.
Background technology
The structure of contact terminal of existing closed type contactor be all using etc. the cylindrical static contact of radius matched with moving contact,
When product is performing bringing onto load opening operation, electric arc will be produced between static contact and moving contact, between dynamic/static contact
Distance constantly increase, electric arc can also be elongated and finally extinguish.But existing structure of contact terminal due to be using etc. radius cylinder
Static contact is matched with moving contact, is unfavorable for the walking and extinguishing of electric arc.
The content of the invention
In order to overcome drawbacks described above, the utility model provides a kind of closed type contactor with arc leading angle, is easy to electric arc
Elongation and extinguishing.
The utility model is to solve the technical scheme that its technical problem is used：A kind of closed type with arc leading angle connects
Tentaculum, including a pair of static contacts and a pair of moving contacts below the static contact, moving contact is in transmission mechanism described in a pair
Driving is lower to be switched on and off to realize the opening and closing of contactor with a pair of static contacts simultaneously, with the static contact close to described dynamic
One end of contact is lower end, and outside is in the side being located remotely from each other using a pair of static contacts, it is characterised in that：Static contact described in a pair
The Outboard Sections of lower end form breach respectively, breach formation arc leading angle.
As further improvement of the utility model, the surface of the arc leading angle is arc-shaped curved surface, and the arc-shaped curved surface is from institute
The lower surface starting for stating static contact is extended on the lateral surface of the static contact.
As further improvement of the utility model, the surface of the arc leading angle is faces directly, and this is faced directly from the static contact
Lower surface starting extend on the lateral surface of the static contact.
As further improvement of the utility model, the static contact is cylinder.
As further improvement of the utility model, moving contact described in a pair is that a moving contacting plate is formed.
The beneficial effects of the utility model are：The closed type contactor with arc leading angle passes through in the lower end of a pair of static contacts
Outboard Sections form breach respectively, breach formation arc leading angle, the surface of the arc leading angle forms arc-shaped curved surface, so as to form change
The cylindrical static contact of radius is matched with moving contact, can make arc-shaped curved surface walking of the electric arc along static contact arc leading angle so that
Electric arc is elongated and extinguished in very short time, so that the electrical performance indexes of contactor are improved, simultaneously because employing change radius
Cylinder static contact, reduce contact material consumption and effectively increase contact room spatial volume, be conducive to contact Indoor Thermal
Amount is scattered and disappeared, so as to further improve the electrical performance indexes of contactor.
Brief description of the drawings
Fig. 1 is the utility model structural representation；
Fig. 2 is the utility model partial structural diagram；
Fig. 3 is structural representation of the utility model electric arc in starting；
Fig. 4 is structural representation when the utility model electric arc is elongated.
With reference to accompanying drawing, make the following instructions：
1 --- static contact 2 --- moving contact

Embodiment
Below in conjunction with accompanying drawing, a preferred embodiment of the present utility model is elaborated.But it is of the present utility model to protect
Shield scope is not limited to following embodiments, i.e., as long as with present utility model application the scope of the claims and description made it is simple
Equivalent changes and modifications, all still belongs within the utility model patent covering scope.
It is a kind of closed type contactor with arc leading angle described in the utility model refering to Fig. 1-2, including a pair of static contacts
1 and a pair of moving contacts 2 below the static contact, a pair of moving contacts can simultaneously and a pair under the driving of transmission mechanism
Static contact switches on and off to realize the opening and closing of contactor.Wherein transmission mechanism is the groups such as coil block, iron core and transmission core bar
Into, static contact is cylinder, and moving contact described in a pair is that a moving contacting plate is formed, and these are all prior arts, then this is no longer
It is described in detail.
Using static contact close to one end of moving contact as lower end, outside is in the side being located remotely from each other using a pair of static contacts, a pair
The Outboard Sections of the lower end of static contact form breach respectively, breach formation arc leading angle 3.
Wherein, the surface of the arc leading angle is arc-shaped curved surface, and the arc-shaped curved surface prolongs from the lower surface starting of the static contact
On the lateral surface for extending the static contact, it is preferred that arc-shaped curved surface extends to quiet from the lower surface center starting of static contact
Somewhere on the lateral surface of contact, the section of plane where the arc-shaped curved surface along a pair of stationary contact axis is in circular arc.Certainly, institute
The surface for stating arc leading angle can also be faced directly, from striking and arc quenching effect for, for cylinder static contact for, striking
The surface at angle is optimal when being arc-shaped curved surface.
Refering to accompanying drawing 3-4, arc extinguishing process of the present utility model under detailed description：Notched static contact in the utility model
1 forms the static contact for becoming radius, and static contact 1 and the original position of moving contact 2 of the change radius contact, and work as moving contact
During 2 action executing separate operation, electric arc 4 can be formed between dynamic and static contact, refering to Fig. 3, electric arc can with dynamic and static contact it
Between distance increasing and be constantly elongated, refering to Fig. 4, electric arc 4 eventually because the energy of needs increase and extinguish.Thus may be used
See, electric arc 4 can walk during motion along the surface that the static contact of change radius is arc leading angle, the surface of the arc leading angle
Play a part of pilot arc so that the walking of electric arc 4 is more prone to, so that electric arc is elongated and put out in very short time
Go out, improve the electrical performance indexes of contactor.
In addition, the utility model reduces contact material consumption and effective as a result of the cylinder static contact for becoming radius
Increase contact room spatial volume, be conducive in the room of contact heat to scatter and disappear, so that the electrical property for further improving contactor refers to
Mark.
