Description
Technical field
This utility model relates to accumulator field, is specifically related to copper sheet copper post joint terminal Welding Structure.
Background technology
Accumulator terminal is battery vitals, and battery terminal has a variety of structure, except copper post and lead base cast structure,
Also having one is copper post and copper sheet rivet welding structure, and production mechanization degree is high, and welding is reliable, and bonding strength is good.At present copper post with
Copper sheet welding all uses one side rivet welding, has certain risk, if solder side is the thinest, welding fluid is difficult to permeate the back side, produces
Raw rosin joint, terminal heating fusing when causing heavy-current discharge, the phenomenon that client twists off copper post occurs.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of copper sheet copper post joint terminal Welding Structure, it is achieved one side
Infiltration welding, conjugation is good, and intensity is high, the torsion of copper core terminal is effectively ensured, it is ensured that high-rate battery discharge performance.
This utility model is achieved through the following technical solutions:
Copper sheet copper post joint terminal Welding Structure, terminal is connected in "Ji" type by copper sheet and copper post, and described copper post is horizontal
The column fallen, its center, outer face is provided with screwed hole, and described copper sheet one end horizontal plane is arranged, and center is provided with welds with battery electrode column
Welding connecting hole A, through bending 90 ° upwards, then 90 ° of levels of bending are to opposite side for horizontal plane copper sheet, and bending 90 ° is downward again,
Be provided with to lower folding surface center and coordinate, with copper post the inner, the welding connecting hole B that weld, described copper post the inner side face be provided with first step with
Second step, second step external diameter is less than first step external diameter, and second step is vertically fitted in the welding connecting hole B of copper sheet, weldering
Setting skew wall opening in connecting hole B, in opening, weldering sets rivet welding point, and infiltrates into first step outer peripheral face and copper sheet gap location, is formed
Infiltration solder joint.
The further improvement project of this utility model is, described first step external diameter is less than copper post external diameter 1-3mm, length of bench
0.2-1mm, the second step external diameter arranged inside first step 13 is less than first step external diameter 0.5-2mm, and length of bench is more than
Copper thickness 1-5mm.
This utility model further improvement project is, described opening angle is 20 °-45 °.
This utility model compared with prior art, has a following obvious advantage:
This utility model Welding Structure is simple, uses one side infiltration welding structure, and conjugation is good, and intensity is high, and copper is effectively ensured
The torsion of core terminal, it is ensured that high-rate battery discharge performance.

Detailed description of the invention
As shown in Fig. 1 to Fig. 3, terminal of the present utility model is connected in "Ji" type by copper sheet 2 and copper post 1, described copper post 1
For the column laid across, its center, outer face is provided with screwed hole 11, and described copper sheet 2 one end horizontal plane is arranged, and center is provided with and battery
The welding connecting hole A 21 of pole welding, through bending 90 ° upwards, then 90 ° of levels of bending are to opposite side, roll over again for horizontal plane copper sheet
Curved 90 ° downwards, be provided with to lower folding surface center and coordinate the welding connecting hole B 22 weld with copper post the inner, described copper post 1 the inner side face
Being provided with first step 12 and second step 13, first step 12 external diameter is less than copper post 1 external diameter 1-3mm, length of bench 0.2-1mm,
Second step 13 external diameter arranged inside first step 12 is more than copper sheet less than first step 12 external diameter 0.5-2mm, length of bench
Thickness 1-5mm, second step 13 external diameter is less than first step 12 external diameter, and second step 13 is vertically fitted in the welding connecting hole of copper sheet
In B 22, setting skew wall opening 23 in welding connecting hole B 22, opening 23 angle is 20 °-45 °, and in opening 23, weldering sets rivet welding point 31, and
Infiltrate into first step outer peripheral face and copper sheet gap location, form infiltration solder joint 32, it is achieved one side infiltration welding structure.Welding is simple,
Conjugation is good, and intensity is high, the torsion of copper core terminal is effectively ensured, it is ensured that high-rate battery discharge performance.
