Centre is contacted to the axle center of circular reed protrusion, protrusion with contact pin, plays the role of turning circuit；In the transmission of new energy high current
Lower temperature rise and lesser contact engaging and separating force are generally required, and the general contact point of existing reed is less, contact engaging and separating force is larger, Wu Faman
To the increasingly higher demands of contact resistance and contact engaging and separating force in sufficient high current transmission.
Summary of the invention
That the technical problem to be solved by the present invention is to the general contact points of existing reed is less, contact engaging and separating force is larger, provide one kind
The cylindrical hat spring that contact point is more, contact engaging and separating force is small.
In order to solve the above technical problems, the present invention adopts the following technical solutions: a kind of cylindrical hat spring, including be arranged in circle
Cylindricality is preced with the upper end band and lower end band at spring both ends, and several reeds being arranged between upper end band and lower end band, each reed
It is upper that there is the contact portion axially extending to cylindrical hat spring.
The reed includes reed I and reed II, and reed I and reed II are along the circumferential direction alternately distributed；Described connects
Contact portion includes the reed I contact portion being arranged among reed I and the reed II contact portion being arranged among reed II.
Axial higher slice distribution of the reed I contact portion and reed II contact portion in cylindrical hat spring.
The reed I is that both ends are connected to the simple beam structure between upper end band and lower end band, and shape is during both ends are wide
Between narrow dumb-bell shape.
The reed II is the cantilever beam structure with upper end band or lower end band connection, and reed II is preced with spring towards cylinder
Middle plane is symmetrical.
The reed II is the narrow spindle-type α-Fe2O3 in intermediate wide both ends, is provided among the reed II contact portion of reed II
The contact point of reed II contact portion is divided into two by one by bowl configurations, bowl configurations.
The end reed II of the cantilever beam structure has the sliding surface that plane extends into cylindrical hat spring.
The present invention using the above structure is made of two kinds of reeds: the design of reed I is simple beam structure；Reed II is outstanding
Arm girder construction, upper and lower two reeds II structure, contact point is double, and in insertion process, initial insertion forces are small, the end reed II
Sliding surface can install face contact with the coil spring of jack, and can forward slip.So this cylinder hat spring combines two kinds of reeds
Advantage, plugs durability and contact stabilization is preferable, is able to satisfy the requirement for transmitting high current in new-energy automobile for a long time, and tie
Structure is easily fabricated.
The present invention has more contact points, can be effectively reduced contact resistance, and the inside protrusion of reed is divided into multilayer,
It can be layered in contact pin insertion process and be contacted with contact pin, the contact engaging and separating force of contact pin is effectively reduced.
Detailed description of the invention
Fig. 1 is schematic perspective view of the invention；
Fig. 2 is longitudinal section schematic cross-sectional view of the present invention；
Fig. 3 is the structural schematic diagram that the present invention cooperates with contact pin, jack.
Specific embodiment
As shown in Figure 1 to Figure 3, the present invention includes the upper end band 101 and lower end band 102 that cylindrical hat 1 both ends of spring are arranged in,
And several reeds between upper end band 101 and lower end band 102 are set, have on each reed axial to cylinder hat spring 1
The contact portion of extension.Upper end band 101 and lower end band 102 are axially arranged along cylinder hat spring.Cylinder contacts face is provided on contact pin 5
501, the hat spring mounting groove 401 of indent is provided on jack 4.
The reed includes reed I2 and reed II3, and reed I2 and reed II3 are along the circumferential direction alternately distributed, this friendship
It can be single reed alternating for distribution, can also be multiple reed alternatings；The contact portion includes being arranged among reed I2
Reed I contact portion 201 and the reed II contact portion 301 that is arranged among reed II3.
Axial higher slice distribution of the reed I contact portion 201 and reed II contact portion 301 in cylindrical hat spring 1.This
On same circumferential position, upper and lower reed II has in the axial direction there are two reed II contact portion 301 sample, in use, can
To effectively reduce the contact resistance between contact pin 5, increase current-carrying capability.
The reed I2 is that both ends are connected to the simple beam structure between upper end band 101 and lower end band 102, shape two
The wide intermediate narrow dumb-bell shape in end.This structure is easily deformable, when contact pin 5 is inserted into, can be effectively reduced insertion force.
The reed II3 is the cantilever beam structure connecting with upper end band 101 or lower end band 102, and reed II3 is towards circle
It is symmetrical that cylindricality is preced with plane in spring 1.In this way on the cylinder hat same circumferential position of spring 1, upper and lower reed II is in axial direction
Upper tool can effectively reduce the contact resistance between contact pin 5 in use there are two switch jaw contact portion 301, increase
Current-carrying capability.Middle plane of the invention referred to the cross section of cylindrical hat spring central point.
The reed II3 is the narrow spindle-type α-Fe2O3 in intermediate wide both ends, among the reed II contact portion 301 of reed II3
Bowl configurations 302 are provided with, the contact point of reed II contact portion 301 is divided into two by one by bowl configurations 302.By reed
The contact point of the cylindrical contact face 501 of II3 and contact pin 5 increases one times, can further decrease contact resistance, increases electric current
Bearing capacity.
The end reed II3 of the cantilever beam structure has the sliding surface 303 that plane extends into cylindrical hat spring 1.
In use, sliding surface 303 is contacted with 401 inner wall of hat spring mounting groove of jack 4, and plane is sliding into cylinder hat spring 1
It is dynamic, in 5 insertion process of contact pin, insertion force is decomposed, also the reliable contacts for reed II3 and contact pin 5 provide effective support force.
In use, the contact surface of reed II3 and reed I2 are successively contacted with the circular contact face 501 of contact pin, drop
Low initial insertion forces realize the electrical contact of cylindrical hat spring 1 and contact pin 5.The upper end band 101 and lower end band 102 of cylinder hat spring 1
It is contacted with 401 inner wall of hat spring mounting groove of jack 4, realizes and be in electrical contact between upper end band 101 and lower end band 102 and jack 4.
