Length.
After first connection sheet 31 is welded with movable contact spring 1, first level piece 33, the first connection sheet 33 and movable contact spring 1 are linked as one
Body, at this point, under the premise of not considering motion parts 81 frictional force of shaft, the 3 motion parts free travel stage of connection sheet by
Resistance (transition that the second horizontal plate 37 both is, active force are mainly formed by the first vertical piece 35 and the second vertical piece 39
It can decompose to the first vertical piece 35 and the second vertical piece 39)；First vertical piece, 35 deflection is maximum, but its Impact direction is along width
Direction (i.e. material is lateral, and strip transverse elasticity coefficient is less than longitudinal direction).And in entire connection sheet 3, in the first vertical piece 35
Width is minimum, is conducive to reduce Torsion Section coefficient, achievees the purpose that reduce resistance；Though the bending stiffness of the second vertical piece 39 compared with
First vertical piece 35 is big, but it is long along coil axial length, is conducive to reduce the resistance of motion (in the certain situation of deflection
Under, the arm of force is longer, and flexibility is bigger, and active force is smaller)；Therefore the connection that movable contact spring 3 is subject in the free travel stage can be effectively reduced
Piece resistance.Therefore, it can choose relatively thick movable contact spring when design；It is (thick to reduce requirement of the movable contact spring to electrical and thermal conductivity
The increase of degree means the increase of conductive cross-sectional area).
Second vertical piece, 35 width is greater than 39 width of the second horizontal plate.Since band longitudinal elastic coefficient is greater than laterally
Coefficient of elasticity, when one timing of material thickness, width is bigger, and bending stiffness is bigger, i.e. the rigidity of material is better；And the second vertical piece 35 with
Second connection sheet 32 is integrally formed, and the second connection sheet 32 is welded and fixed with the exit 2 on pedestal, therefore the second vertical piece 35 is necessary
Have certain rigidity, using as support fixed part.
In the present embodiment, in the other side of the width of second horizontal plate 37, corresponding to third bending part and second
At position between vertical piece, it is additionally provided with the second open slot 371.
In the present embodiment, the tail end of second vertical piece 39 integrally connects with second connection sheet 32, and second is perpendicular
Straight piece 39 and the second connection sheet 32 are in approximately the same plane, in the side of the width of the second vertical piece 39, are additionally provided with second
Step 391, the second step 391 make the width dimensions close to the 4th bending part in the second vertical piece 39 less than the second vertical piece
In close to the second connection sheet width dimensions.
In the present embodiment, in the other side of the width of second vertical piece 39, at the position close to the 4th bending part,
It is additionally provided with third open slot 392.
In four bending parts of connection sheet 3 of the invention, the bending line of the 4th bending part 40 can be set as longest, thus
Avoid insufficient rigidity that head is made to shake and influence assembly；The bending line of second bending part 36 is set as most short, it is ensured that it has
Standby certain flexibility, to reduce the active force to movable contact spring.Wherein, the bending angle of the 4th bending part 40 a certain range can be with
It is adjusted, to compensate influence of the head welding position deviation to rotational travel, to minimize the deflection of connection sheet.
In three open slots of connection sheet 3 of the invention, shape can be " u "-shaped or " V " shape；It is mainly used for improving folding
Bending process improves Angular Dimension stability.
The first step 351 of connection sheet 3 of the invention is stepped down for movable contact spring 1, avoids generating interference when dynamic spring movement；
Relay inner space is made full use of simultaneously, keeps structure more compact.The second step 391 of connection sheet 3, position must not height set out
Reed lower edge；It avoids damaging connection sheet during the adjustment of the laser dotting of movable contact spring
In the present embodiment, the movable contact spring 1 is equipped with third step 13 in the one side of thickness, and third step 13 is located at dynamic spring
The approximate mid-section position of piece makes the thickness at the rear portion of movable contact spring be greater than the thickness of the front of movable contact spring, the third
Step 13 is sloping platform rank.In this way, the rear portion of movable contact spring is thicker just by step as boundary, the front of movable contact spring is relatively thin, and
Open slot 14 is equipped with compared with thin structure.
Dynamic spring step is positioned approximately at movable contact spring middle position by the present invention, and the plane of step and movable contact spring is in an oblique angle,
Oblique angle is used to increase the bit space that allows of movable contact spring and exit, and movable contact spring and exit is avoided to interfere.Thicker one section of movable contact spring
Effect is；First is that conductive cross-sectional area can be increased, current-carrying capability is improved, while reducing the requirement to materials conductive thermal conductivity；Two
It is to increase reed rigidity, guarantees that reed is not deformed in the free travel of motion parts, it is tired reaches reduction material resistance to mechanical
The purpose of labor characteristic.Open slot 14 is equipped at relatively thin one section of movable contact spring, open slot 14 is for increasing spring compliance, to improve reed
Fatigue-resistance characteristics increase contact contact reliability.This movable contact spring structure of the invention, thicker portion is in rigidity, thinner part
In flexibility, thinner part can be made to generate bending deformation, final realize surpasses relay by carrying out laser dotting to thicker portion
The adjustment of stroke；The generation for being conducive to reduce reed stress, improves parameter consistency.
A kind of movable contact spring of relay of the invention and the connection structure of exit, are designed to have using by movable contact spring 1
There is the tail portion 11 of rigid structure feature and has the characteristics that the head 12 of flexible structure；Connection sheet 3 is connected to the tail portion of movable contact spring
Between 11 and exit 2；And connection sheet 3 is the electrically conductive sheet metal of multiple bending and moldings, at the both ends point of the length of connection sheet 3
The first connection sheet 31 that She You be used to be connected with the tail portion of movable contact spring and the second connection sheet for being connected with exit
32, and the first connection sheet 31 and the second connection sheet 32 are in respectively in two substantially parallel planes, in 31 He of the first connection sheet
It is connected with the middle section that multiple bendings are formed between second connection sheet 32, and makes the first connection sheet 31 and the second connection sheet 32
It is in be dislocatedly distributed in height and length direction.The present invention is by carrying out Function Decomposition to dynamic spring part, by resistance to mechanical therein
Fatigue properties are stripped out, so that motion parts only have connection structure to be deformed during free travel, and movable contact spring is only
Have in overtravel stage ability stress deformation；Simultaneously by the optimization design to connection structure, reduce in motion parts action process
The deflection of connection structure, to reduce its demand to mechanical resistant fatigue properties；Finally make product that there is compact-sized, bringing onto load
