Meanwhile the hot melting way can be that laser light source heats tin material.
Shown first embodiment is please referred to Fig.1 to Fig.3, discloses a kind of conducting terminal ball shape welding joint structure 1000, it is described to lead
Electric terminal ball shape welding joint structure 1000 includes conducting terminal 100 and solder 200, and the conducting terminal 100 includes being used for being welded on described
The leg 1 of conducting element, the definition of conducting terminal 100 have upper surface 101 and lower surface 102, and the definition of leg 1 has freedom
End 10.The leg 1 is equipped with through thereon, the mounting hole 11 of lower surface 101,102；The solder 200 is placed on described solid
Determine in hole 11, the mounting hole 11 of the leg 1 runs through forward the free terminal 10 of the leg 1 so that the front of mounting hole 11
Guiding notch 12 is formed, the guiding notch 12 is formed in free terminal 10 in the guiding face 13 for expanding shape.The solder 200
It is first retained in the mounting hole 11, then the leg 1 is welded on the conducting element by way of hot melt.It is described to lead
Electric terminal 100 further includes the elastic portion 2 from the leg 1 bending extension, and the leg 1 is arranged to tabular in order to be formed with
Welding surface with certain flatness, the elastic portion 2 be arranged to micro-arc shape from the leg 1 be folded upward at after again level prolong
It stretches, the elastic portion 2 has elasticity with to forming precompression between the leg 1 and the conducting element, can be in assembling product
Elastic deformation space is provided after good to meet the needs of various products construction.
The upper surface 101 of the conducting terminal 100 is equipped with downward concave first guide channel 31, lower surface 102 be equipped with to
Upper concave second guide channel 32 so that the conducting terminal 100 forms slim portion between first, second guide channel 31,32
3, the mounting hole 11 and guiding notch 12 are through the upper and lower surface in the slim portion 3.In the width and thickness of the leg 1
On direction, the slim portion 3 is respectively positioned on the middle position of the leg 1.First, second guide channel 31,32 is from the weldering
Foot 1 extends to the elastic portion 2 of bending, and the elastic portion 2 is higher than the leg 1 during welding, therefore the solder 200 is heated
After melting can mounting hole 11 described in the guiding lower edge in first guide channel 31 and guiding notch 12 flow into it is described second guiding
The conducting terminal 100 stabilization is simultaneously weldingly fixed on the conducting element by slot 32.Since the mounting hole 11 and guiding lack
The area of mouth 12 is larger, and the solder 200 of melting can successfully be flowed down with faster speed, can in order to be welded in time
Improve the welding quality between conducting terminal 100 and conducting element.Meanwhile the solder 200 of melting can converge in it is described
It is overflowed without one way or another in first, second guide channel 31,32 and influences welding effect.

Portion 201 and the main part 202 for the setting that is recessed between head 201, the main part 202 pass through the mounting hole 11, two
The head 201 is then located at the both sides up and down in the slim portion 3 respectively.The solder 200 can so be allowed to be welded with conducting element
Pre-contact is realized before connecing, improves welding quality.When the solder 200 is assembled to the conducting terminal 100, the solder 200
Main part 202 via the guiding face 13 through it is described guiding notch 12 and interfere be fixed in the mounting hole 11.Due to
The guiding face 13 is arranged on the free terminal 10 of the leg 1 and is set in shape is expanded, and contributes to the main body of the solder 200
Portion 202 is smoothly into the guiding notch 12.
The second embodiment shown in Fig. 4 to Fig. 6 is referred to, the utility model second embodiment discloses a kind of conducting terminal
Ball shape welding joint structure 1000 ', the conducting terminal ball shape welding joint structure 1000 ' be also to be fixed to a conducting element with the conductive element
Part generates electric connection.The conducting terminal ball shape welding joint structure 1000 ' includes conducting terminal 100 and solder 200 ', the conducting end
Sub- ball shape welding joint structure 1000 ' from 1000 difference lies in the solder 200 ' shape it is different with the solder 200, i.e. this practicality is new
The solder that conducting terminal 100 in type can be constructed with different shape is used cooperatively, and exploitativeness is stronger.
In this second embodiment, the solder 200 ' is arranged to spherical structure, and the maximum width of the mounting hole 11 connects
Diameter near but no more than the 200 ' maximum cross-section of solder, the solder 200 ' are placed and are positioned in the mounting hole 11,
The solder 200 ' stretches out the lower surface of the conducting terminal 100.So achievable solder 200 ' is being welded with conducting element
Preceding pre-contact improves welding quality.Specifically, the diameter of the rounded setting of the mounting hole 11 and the mounting hole 11 approaches
But no more than the diameter of the 200 ' maximum cross-section of solder, the guiding notch 12 and the width of the junction of mounting hole 11 are less than
The diameter of the mounting hole 11.In this way, spherical solder 200 ' is in the stop of the guiding notch 12 and the card of mounting hole 11
It holds down, can be stably placed in the mounting hole 11.Likewise, due to the mounting hole 11 and guide notch 12 area compared with
Greatly, the solder 200 ' of melting can successfully be flowed down with faster speed, in order to be welded in time, can improve conducting terminal
Welding quality between 100 and conducting element.
It is lacked in conclusion the conducting terminal 100 of the utility model conducting terminal ball shape welding joint structure is equipped with the guiding that connection is set
Mouth 12 and mounting hole 11, add inflow area during melt solder, accelerate the flow rate of solder, so that most of solder energy
It is enough to be contacted in time with conducting element, the solder can be allowed to be fully used and leg 1 and conducting element can be improved
Welding quality.Meanwhile the conducting terminal 100 can be fixed to form this reality with the solder that different shape constructs with carrying out cooperation
With new electric terminal ball shape welding joint structure, thus the utility model conducting terminal ball shape welding joint structure have stronger practicability with it is pervasive
Property.
