Description

A kind of new cylinder hat spring

Technical field

A kind of parts of electric automobile electric connector of this utility model, and in particular to a kind of to be used to carry out high current transmission Cylinder hat spring.

Background technology

At present in the transmission of new-energy automobile high current, in order to ensure that contact pin and jack are reliably electrically connected, typically inserting Elastic spring is provided with hole, typically in cage type, the connect band middle setting at two ends has the spring bar of rectangle, spring bar to existing reed The middle axle center to circular reed is raised, and projection is contacted with contact pin, plays a part 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 be full Higher and higher requirement in sufficient high current transmission to contact resistance and contact engaging and separating force.

Utility model content

The technical problems to be solved in the utility model is that the general contact point of existing reed is less, contact engaging and separating force is larger, there is provided A kind of contact point is more, the little new cylinder hat spring of contact engaging and separating force.

To solve above-mentioned technical problem, this utility model adopts following technical proposals：A kind of new cylinder hat spring, bag Include the upper end band and lower end band for being arranged on cylinder hat spring two ends, and some springs being arranged between upper end band and lower end band Piece, with to the axially extending contact site of cylinder hat spring on each reed.

Described reed includes that reed I and reed II, reed I and reed II are along the circumferential direction alternately distributed；Described connects Contact portion includes the reed I contact sites being arranged in the middle of reed I and the reed II contact sites being arranged in the middle of reed II.

Described reed I contact sites and reed II contact sites are distributed in the axial higher slice of cylinder 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 two ends alleviating distention in middle-JIAO 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 cylinder 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 settings of reed II have The contact point of reed II contact sites is divided into two by one by bowl configurations, bowl configurations.

The reed II ends of described cantilever beam structure are with the sliding surface extended to plane in cylinder hat spring.

It is made up of two kinds of reeds using this utility model of said structure：The design of reed I is simple beam structure；Reed II For cantilever beam structure, upper and lower two reeds II structures, contact point is double, and in insertion process, initial insertion forces are little, and reed II is last The sliding surface at end can be contacted with the coil spring mounting surface of jack, and can forward slip.So this cylinder hat spring combines two kinds of springs The advantage of piece, plug durability and contact stabilization preferably, transmit the requirement of high current for a long time in meeting new-energy automobile, And structure is easily fabricated.

This utility model has more contact points, can effectively reduce contact resistance, and the inside projection of reed is divided into Multilamellar, can be layered in contact pin insertion process and contact with contact pin, effectively reduce the contact engaging and separating force of contact pin.

Specific embodiment

As shown in Figure 1 to Figure 3, this utility model includes the upper end band 101 and lower end band for being arranged on 1 two ends of cylinder hat spring 102, and upper end is arranged on 101 and lower end with some reeds between 102, with to cylinder hat spring 1 on each reed Axially extending contact site.Upper end band 101 and lower end band 102 are axially arranged along cylinder hat spring.Cylinder is provided with contact pin 5 to connect Contacting surface 501, is provided with the hat spring mounting groove 401 of indent on jack 4.

Described reed includes that reed I2 and reed II3, 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 sites 201 and the reed II contact sites 301 being arranged in the middle of reed II3.

Described reed I contact sites 201 and reed II contact sites 301 are distributed in the axial higher slice of cylinder 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 and the contact resistance between contact pin 5, increase current capacity.

Described reed I2 is connected to upper end with 101 and lower end with the simple beam structure between 102 for two ends, is shaped as two Narrow dumb-bell shape between the alleviating distention in middle-JIAO of end.This structure is easily deformable, when contact pin 5 is inserted, can be effectively reduced insertion force.

Described reed II3 be with upper end with 101 or lower end with 102 cantilever beam structures being connected, reed II3 is towards circle 1 middle position face of cylindricality hat spring is symmetrical.So on the same circumferential position of cylinder hat spring 1, upper and lower reed II is in axial direction It is upper in use, to effectively reduce and the contact resistance between contact pin 5 with two switch jaw contact portions 301, increase Current capacity.Middle plane of the present utility model referred to the cross section of cylinder 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 sites 301 of reed II3 Bowl configurations 302 are provided with, the contact point of reed II contact sites 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 further reduce contact resistance, increase electric current Bearing capacity.

The reed II3 ends of described cantilever beam structure are with the sliding surface 303 extended to plane in cylinder hat spring 1. In use, sliding surface 303 is contacted with 401 inwall of hat spring mounting groove of jack 4, and is slided to plane in cylinder hat spring 1 It is dynamic, in 5 insertion process of contact pin, decompose insertion force, also provide effective support force with the reliable contacts of contact pin 5 for reed II3.

In use, the contact surface of reed II3 and reed I2 is contacted with the circular contact face 501 of contact pin successively, drop Low initial insertion forces, realize the electrical contact of cylinder hat spring 1 and contact pin 5.The upper end band 101 and lower end band 102 of cylinder hat spring 1 Contact with 401 inwall of hat spring mounting groove of jack 4, realize making electrical contact between upper end band 101 and lower end band 102 and jack 4.
