Electrode terminal 100 according to embodiments of the present invention is described in detail with reference to accompanying drawing first below.
As shown in Figure 1 to Figure 3, electrode terminal 100 according to embodiments of the present invention includes leading-out terminal 10 and connection ring 20.
Specifically, connection ring 20 and leading-out terminal 10 are made up of different metal materials.The outer peripheral face of leading-out terminal 10
Flange 12 is provided with, connection ring 20 is enclosed on the upper end 11 of leading-out terminal 10 and welded with leading-out terminal 10, and connection ring 20 is located at
The top of flange 12.Wherein, the upper surface of flange 12 is provided with least one in the lower surface of connection ring 20 is located at flange
Boss 50 between 12 upper surface and the lower surface of connection ring 20.
Electrode terminal 100 according to embodiments of the present invention, passes through the lower surface in the upper surface of flange 12 and connection ring 20
In at least one on set and be located at boss 50 between connection ring 20 and flange 12 so that the upper surface of flange 12 and connection ring
20 lower surface can be spaced apart and incomplete contact between, when connection ring 20 be enclosed on the upper end 11 of leading-out terminal 10 and with extraction
When terminal 10 welds together, boss 50 need to only be welded together with the lower surface of connection ring 20 or the upper surface of flange 12
, without together with the integral solder of flange 12, so as to reduce bonding area, connection ring 20 is made into what flange 12 was subject to
Welding stress reduces, it is to avoid flange 12 deforms, and then improves the sealing and fixing of electrode terminal 100.
It is additionally, since leading-out terminal 10 and connection ring 20 is made up of different metal materials, therefore, the electricity is used in connection
During the cell of extreme son 100, the welding between different metal material can be avoided, for example when the metal terminal be copper into
Negative terminal when, connection ring 20 can be with made of aluminum, so as to the power connections connection cell that is formed from aluminium
Electrode terminal 100, connection ring 20 and power connections weld, it is to avoid the welding between copper and aluminium, add bonding strength, no
Easily produce welding gap, salt fog resistance by force, contact resistance is small, the performance of battery pack is improved, moreover, reducing welding cost
Height, simplifies technique, has a wide range of application.
Specifically, according to one embodiment of present invention, flange 12 can include the first ring being connected with leading-out terminal 10
Shape flat part 121, the annular inclined part 122 for downwardly and outwardly tilting from the outer of first annular flat part 121 extension and from annular
Outside the second horizontal-extending annular flat part 123 of rake 122, the periphery edge of first annular flat part 121 and connection ring 20
Periphery along concordant or extend outwardly beyond the periphery edge of connection ring 20.Alternatively, according to one embodiment of present invention, boss
50 are located on first annular flat part 121.Further, the lower surface of first annular flat part 121 and leading-out terminal 10 is outer
Arc transition between side face.
Level height highest plane is the upper surface of first annular flat part 121 i.e. on flange 12, first annular flat
The upper surface in straight portion 121 is provided with boss 50, the company of the lower surface of first annular flat part 121 and the outer peripheral face of leading-out terminal 10
The place of connecing is formed as circular arc, and sectional dimension of the sectional dimension more than or equal to connection ring 20 of first annular flat part 121.
Wherein, in certain specific embodiments of the invention, flange 12 is integrally formed with leading-out terminal 10.Thus, one
The structure not only convenient formation of body formation, reduces preparation cost, and ensure that the overall structure stability of leading-out terminal 10,
Also make the connection of whole electrode terminal 100 more firm simultaneously.
The structure of boss 50 can rationally be set according to specific requirement, alternatively, according to the reality of the present invention
Example is applied, boss 50 is annular.I.e. boss 50 is located between connection ring 20 and flange 12, and is formed as annular.As a result, connection
Can form annular contact surface between ring 20 and flange 12, the lower surface of connection ring 20 in welding can around leading-out terminal 10 with
Flange 12 forms complete annular welds junction, makes welding more firm.
Further, according to one embodiment of present invention, boss 50 is multiple, and multiple boss 50 are disposed concentrically upon and edge
Leading-out terminal 10 is spaced radially from each other.As shown in figure 9, boss 50 is formed as two, two intervals of boss 50 are located at flange
On 12 upper surface, the height of two boss 50 is equal so that the upper surface of two boss 50 can with connection ring 20
Surface is contacted, and then enables connection ring 20 with two boss 50 while welding together, and increases bonding area, welding position
Evenly, weld more firm.
Certainly, the setting of boss 50 is not limited only to this, for example, in other embodiments of the present invention, boss
50 are located on the lower surface of connection ring 20.Be located at boss 50 it is similar on flange 12, when boss 50 is located at the following table of connection ring 20
When on face, the structure of boss 50 may be alternatively formed to annular, and the quantity of boss 50 can be multiple, and be spaced apart setting, therefore, its
Concrete structure and technique effect are repeated no more.
The material for preparing of connection ring 20 and leading-out terminal 10 can be the electrode material that those of ordinary skill in the art commonly use,
Alternatively, according to one embodiment of present invention, connection ring 20 is aluminium ring, and leading-out terminal 10 is copper tip.That is, connection
Ring 20 is prepared from for aluminum material, and leading-out terminal 10 is prepared from for copper material.In other specific implementations of the present invention
In mode, connection ring 20 can also be copper ring, and leading-out terminal 10 is aluminium terminal.
According to one embodiment of present invention, the radial dimension of the upper end 11 of leading-out terminal 10 is less than leading-out terminal 10
The radial dimension of remainder.That is the radial dimension of the upper end 11 of leading-out terminal 10 is minimum, the flange 12 on leading-out terminal 10
Radial dimension it is larger.Now, when being arranged connection ring 20 on the upper end 11 in leading-out terminal 10, the size of connection ring 20 can
With smaller, so as to save material usage.Meanwhile, the upper end 11 of leading-out terminal 10 is smaller to be also easier to enclosed electrode terminal
100。
Further, since connection ring 20 is set on the upper end 11 of leading-out terminal 10, when the upper end 11 of leading-out terminal 10
When changing, connection ring 20 should also make corresponding change.For example, according to one embodiment of present invention, in connection ring 20
Heart hole 61 and the upper end of leading-out terminal 10 11 have noncircular cross section.That is the upper end 11 of leading-out terminal 10 is formed as non-cylindrical
Shape, correspondingly, the shape of the centre bore 61 of connection ring 20 be again formed as it is non-circular, with the shape with the upper end 11 of leading-out terminal 10
Shape is adapted to.
It should be noted that electrode terminal 100 according to embodiments of the present invention, can be located at the positive pole of battery, can also
It is located at the negative pole of battery.Because the positive pole of battery is usually aluminium electrode, negative pole is usually copper electrode.Therefore, when according to the present invention
When the electrode terminal 100 of embodiment is located at the positive pole of battery, leading-out terminal 10 is copper tip, and connection ring 20 is then aluminium ring.Work as root
When being located at the negative pole of battery according to the electrode terminal 100 of the embodiment of the present invention, leading-out terminal 10 is aluminium terminal, and connection ring 20 is then copper
Ring.
