Abstract
The invention provides a new type cylindrical crown spring. The invention is designed to mainly solve the problems in the prior art that a conventional spring is usually equipped with few contact points and requires large plugging force. According to the invention, a plurality of spring sheets are arranged at the upper end band and the lower end band of a crown spring's two ends as well as between the upper end band and the lower end band. Each spring sheet is provided with a contact part that can axially extend to the cylindrical crown spring. With the technical schemes of the invention, more contact points are available, which can effectively reduce the contact resistance. Further, as the inward protrusions of the spring sheets are divided into a plurality of layers, layers can be divided for the contact with the plugging needles in the process of plugging needle insertion, which effectively reduces the plugging force of insertion needles.

The middle axle center to circular reed is raised, and projection is contacted with contact pin, plays the effect of turning circuit；In the transmission of new forms of energy high current
Typically require relatively low temperature rise and less contact engaging and separating force, and the general contact point of existing reed is less, contact engaging and separating force is larger it is impossible to full
Higher and higher requirement to contact resistance and contact engaging and separating force in sufficient high current transmission.
Content of the invention
The technical problem to be solved in the present invention is that the general contact point of existing reed is less, contact engaging and separating force is larger, provides one kind
Contact point is many, the little new cylindrical hat spring of contact engaging and separating force.
For solving above-mentioned technical problem, the present invention adopts following technical proposals: a kind of new cylindrical hat spring, including setting
Put the upper end band at cylindrical hat spring two ends and lower end band, and be arranged on some reeds between upper end band and lower end band, often
Have on individual reed to the cylindrical hat axially extended contact site of spring.
Described 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 site being arranged in the middle of reed i and is arranged on the reed ii contact site in the middle of reed ii.
Described reed i contact site and reed ii contact site are distributed in the axial higher slice of cylindrical hat spring.
Described reed i is connected to the simple beam structure between upper end band and lower end band for two ends, is shaped as in the width of two ends
Between narrow dumb-bell shape.
Described reed ii is the cantilever beam structure being connected with upper end band or lower end band, and reed ii is towards cylindrical hat spring
Middle position face is symmetrical.
Described reed ii is the narrow spindle-type α-Fe2O3 in middle width two ends, and the reed ii contact site middle setting of reed ii has
Bowl configurations, the contact point of reed ii contact site is divided into two by one by bowl configurations.
The reed ii end of described cantilever beam structure has the sliding surface extending to plane in cylindrical hat spring.
The present invention using said structure is made up 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 reed ii structures, contact point is double, and in insertion process, initial insertion forces are little, reed ii end
Sliding surface can be contacted with the coil spring installed surface of jack, and can forward slip.So this cylinder hat spring combines two kinds of reeds
Advantage, plug durability and contact stabilization preferably, can meet the long-time requirement transmitting high current in new-energy automobile, and tie
Structure is easily fabricated.
The present invention has more contact points, can effectively reduce contact resistance, and the inside projection of reed is divided into multilayer,
Contact pin insertion process can be layered and contact with contact pin, effectively reduce the contact engaging and separating force of contact pin.
Brief description
Fig. 1 is the perspective view of the present invention；
Fig. 2 is longitudinal section of the present invention cross section structure diagram；
Fig. 3 is the structural representation of the present invention and contact pin, jack cooperation.
Specific embodiment
As shown in Figure 1 to Figure 3, the present invention includes upper end band 101 and the lower end band 102 being arranged on cylindrical hat spring 1 two ends,
And it is arranged on some reeds between upper end band 101 and lower end band 102, each reed has to cylindrical hat spring 1 axially
The contact site extending.Upper end band 101 and lower end band 102 are axially arranged along cylindrical hat spring.Cylinder contacts face is provided with contact pin 5
501, jack 4 is provided with the hat spring mounting groove 401 of indent.
Described reed includes reed i2 and reed ii3, and reed i2 and reed ii3 are along the circumferential direction alternately distributed, this friendship
Can be that single reed replaces for distribution, may also be multiple reeds and replace；Described contact site includes being arranged in the middle of reed i2
Reed i contact site 201 and be arranged on the reed ii contact site 301 in the middle of reed ii3.
Described reed i contact site 201 and reed ii contact site 301 are distributed in the axial higher slice of cylindrical hat spring 1.This
On same circumferential position, upper and lower reed ii has two reed ii contact sites 301 to sample in the axial direction, in use, can
To effectively reduce the contact resistance and contact pin 5 between, increase current capacity.
Described reed i2 is connected to the simple beam structure between upper end band 101 and lower end band 102 for two ends, is shaped as two
Narrow dumb-bell shape in the middle of end is wide.This structure is easily deformable, when contact pin 5 inserts, can be effectively reduced insertion force.
Described reed ii3 is the cantilever beam structure being connected with upper end band 101 or lower end band 102, and reed ii3 is towards circle
Cylindricality hat spring 1 middle position face is symmetrical.So on the same circumferential position of cylindrical hat spring 1, upper and lower reed ii is in axial direction
On there are two switch jaw contact portions 301, in use, the contact resistance and contact pin 5 between can be effectively reduced, increase
Current capacity.The middle plane of the present invention referred to the cross section of cylindrical hat spring central point.
Described reed ii3 is the narrow spindle-type α-Fe2O3 in middle width two ends, in the middle of the reed ii contact site 301 of reed ii3
It is provided with bowl configurations 302, the contact point of reed ii contact site 301 is divided into two by one by bowl configurations 302.By reed
Ii3 increased one times with the contact point of the cylindrical contact face 501 of contact pin 5, can reduce contact resistance further, increases electric current
Bearing capacity.
