Specific implementation mode
Below in conjunction with the accompanying drawings, it is described in detail by the specific implementation mode to the present invention, technical scheme of the present invention will be made
And other advantageous effects are apparent.It is appreciated that attached drawing is only for reference and description, not it is used for limiting the present invention
System.The size shown in attached drawing is intended merely to facilitate clear description, and does not limit proportionate relationship.
A is please referred to Fig.1, Figure 1A shows the contact system 1 of the shutdown relay using substantially v-shaped contact holder 2.Its
In, V-type contact holder 2 includes two spring arms 3.1,3.2, is passed through between the first upper spring arms 3.1 and the second lower spring arms 3.2
The interconnecting piece 4 of rounding is connected to each other.The contact system 1 movably connects for switching the first static fixed contact therefor 5 and second
Contact between contact element 6.Below the second lower spring arms 3.2, movable contact 6 is arranged in end 3.2a of the spring arm
It sets.Matched, fixed contact therefor 5 is fixed in an electrically conductive manner on the first component 7, the first component 7 relative to after
Casing for electric appliances is fixed.Movable contact 6 works with fixed contact therefor 5 so that handoff functionality may be implemented in contact system 1.
In present embodiment, the relay further includes armature and at least one magnet exciting coil, the magnet exciting coil due to its magnetic field and
Power is generated, and then the armature acts on the contact system 1 by the power, realizes the handoff functionality of the contact system.
In present embodiment, contact 5,6 is fixed for interrupting or closing relative to casing of relay, is also hereinafter referred to as
Circuit between lower conductor rail and two components 7,8 of upper conductor rail.Two conductor rails 7,8 fixed relative to casing of relay and
In shutdown relay.On the upper surface of upper conductor rail 8, end that contact holder 2 passes through the first upper spring arms 3.1
3.1a is connect with upper conductor rail 8 in an electrically conductive way securely.Fixed contact therefor 5 is directly arranged at the upper surface of lower conductor rail 7
And it is connected thereto in an electrically conductive way.
In present embodiment, the contact holder 2 of the contact system 1 is full slice system structure.Due to spring arm 3.1 and 3.2
Between be acute angle, therefore two spring arms 3.1,3.2 are V-shaped relative to each other.Therefore, two at the interconnecting piece 4 of rounding
A spring arm 3.1, the distance between 3.2 is very small, this small distance ensures that its galvanomagnetic-effect has powerful active force.In electricity
In the case that stream flows to movable contact 6 and then flow to fixed contact therefor 5 by contact holder 2, electric current is in two spring arms
3.1, the direction flowed in 3.2 to which the magnetic field generated generates one between two spring arms 3.1,3.2 with distance on the contrary, have
The repulsive force of pass, two spring arms 3.1, the distance between 3.2 are smaller, and the repulsive force of generation is bigger.
Since first upper spring arms 3.1 is fixedly connected with upper conductor rail 8, second lower spring arms 3.2 is described
First upper spring arms 3.1 is repelled and then is pushed, and then is applied in movable contact 6 so that movable contact 6 is pressed into fixation
On contact 5.The electric current flowed through on the contact element holder 2 is bigger, and the repulsive force of generation is bigger.Particularly, this repulsive force exists
Particularly critical when breaking down, repeat circuit can flow through the electric current more than 4kA in a short-circuit situation, and therefore contribute to
Movable contact 6 will not leave fixed contact therefor 5 due to the raising of lifting force.That contact holder 2 flexible has alignment is in V
Two spring arms 3.1,3.2 of shape so that the contact force that is preloaded from contact holder 2 and magnetic repulsion from contact holder 2 it
With more than lifting force.
In present embodiment, the contact holder 2 is designed as multilayer, and different parallel layers can be different materials, to
Take into account the mechanical performance and electric conductivity of contact holder 2.Further, by using certain materials, bullet can most preferably be set
Property attribute.Furthermore it is also possible to change conductivity by material.In addition, existing distance also has between each layer of contact holder 2
Conducive to high efficiency and heat radiation.
Figure 1B shows the embodiment of the contact holder 2 for the multilayered structure that contact system 1 is made of multi-part.This embodiment party
In formula, contact holder 2 is made of two individual components.The first component includes upper spring arms 3.1, the end of upper spring arms 3.1
3.1a is connected to the downside of conductor rail 8.Lower spring arms 3.2 is arranged in the other end of upper spring arms 3.1, and this results in multi-parts
The second part of formula contact point holder 2.In interconnecting piece 4'In, two spring arms 3.1,3.2 are arranged parallel to each other and with conduction
Mode is connected to each other.In present embodiment, two spring arms 3.1,3.2 be in alignment with each other and it is V-shaped arrange relative to one another, sharp
The interconnecting piece 4&apos on the vertex of wedge angle at angle;In be interconnected.In present embodiment, interconnecting piece 4'Be not round on the vertex
's.In the lower section of the second lower spring arms 3.2, movable contact 6 is arranged in the end regions 3.2a of spring arm.It is matched
, fixed contact therefor 5, which is connected to, to be fixed in an electrically conductive manner on the first component on casing of relay (lower conductor rail) 7.
The other embodiments of the contact system 1 of shutdown relay are shown in Fig. 1 C and Fig. 1 D, wherein contact holder 2 is whole
It slice structure and is only made of single layer.
According to Fig. 1 C, contact holder 2 is arranged in the lower section of conductor rail 8.Upper spring arms 3.1 and lower spring arms 3.2
Interconnecting piece 4 be designed to arc-shaped.
In the alternative variations of contact system 1 shown in Fig. 1 D, the interconnecting piece 4 of contact holder 2 is " in generally circular
Hollow-cylindrical designs.Round or substantially hollow cylinder join domain 4 " wall on small opening form two opposite springs
Minimum range between arm 3.1,3.2.Therefore, in the implementation modification, flexible contacts holder 2 includes a shorter region, i.e.,
The distance between the opposed inner walls of the contact holder, that is to say, that i.e. hollow cylindrical join domain 4 " diameter be not less than
The value of maximum distance between the end 3.1a and 3.2a of spring arm.End 3.1a, 3.2a of described two spring arms 3.1,3.2
The distance between refer to the point that movable contact 6 is corresponded on the spring arm 3.2, on the spring arm 3.1 with upper conductor rail
The distance between the corresponding points of end 3.1a of 8 connections.Wherein, the two point and join domain 4 " on small opening between have
Identical distance.
