【Specific embodiment】

The specific embodiment of the utility model conducting terminal ball shape welding joint structure is introduced with reference to Fig. 1 to Fig. 3.The utility model it Conducting terminal ball shape welding joint structure 1000 is electrically connected to be fixed to a conducting element (not shown) with being generated with the conducting element. The conducting terminal ball shape welding joint structure 1000 includes conducting terminal 100 and solder 200, by way of heating solder 200 by described in Conducting terminal 100 is welded and fixed to conducting element.The material of the solder 200 can be tin material, and the structure of the solder 200 can To be diversified, the conducting element is welded and fixed to as long as the conducting terminal 100 can be stablized, meanwhile, institute It can be that laser light source heats tin material to state hot melting way.The conducting terminal 100 includes being used for being soldered to the conducting element Leg 1, the definition of conducting terminal 100 have upper surface 101 and lower surface 102, and the definition of leg 1 has free terminal 10, institute It states leg 1 and is equipped with the collecting opening 11 for running through the upper and lower surface 101,102, the opening 11 that accommodates runs through forward the weldering The free terminal 10 of foot 1, the leg 1, which is additionally provided with, protrudes into the fixed feet 12 for accommodating opening 11, and the solder 200 plugs In the fixed feet 12 and it is contained in described accommodate in opening 11.In the present embodiment, the solder 200 is tin material, and described Solder 200 is first inserted in the fixed feet 12, then the leg 1 is welded in institute in a manner that laser light source heats tin material State conducting element.

The conducting terminal 100 further includes the elastic portion 2 from the leg 1 bending extension, and the leg 1 is arranged to tablet For shape in order to be formed with the welding surface (not indicating) with certain flatness, the elastic portion 2 is arranged to micro-arc shape from the weldering Foot 1 is horizontal-extending again after being folded upward at, and the elastic portion 2 has elasticity with to shape between the leg 1 and the conducting element Into precompression, can meet the needs of various products construction providing elastic deformation space after product group installs.

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 free terminal 10 of the leg 1 is run through forward in the slim portion 3, and the collecting opening 11 and fixed feet 12 run through and set It is placed in the slim portion 3.On the width and thickness direction of the leg 1, the slim portion 3 is respectively positioned in the leg 1 Entreat position.

As shown in Fig. 2, on the width of the leg 1, the width for accommodating opening 11 is less than described first, the The width of two guide channels 31,32, the fixed feet 12 are in the cantilever-shaped setting for accommodating and extending in opening 11.In this implementation In example, the fixed feet 12 is arranged to elongated strip and from accommodating the 11 lateral collectings away from free terminal 10 of opening Extension in opening 11.The fixed feet 12 is located at the centre position for accommodating opening 11 and opens the collecting in the width direction Mouth 11 is separated into identical two parts, to facilitate the solder 200 being plugged in the fixed feet 12 that can uniformly be housed in institute It states in collecting opening.First, second guide channel 31,32 extends to the elastic portion 2 of bending from the leg 1, welding Shi Suoshu elastic portions 2 are higher than the leg 1, therefore can leading in first guide channel 31 after 200 melted by heating of the solder Draw and 11 inflow of opening, second guide channel 32 is accommodated described in lower edge and is weldingly fixed on the conducting terminal 100 stabilization described On conducting element.The solder 200 stretches out the lower surface 102 of the conducting terminal 100, is arranged such and the solder can be achieved 200 with the pre-contact of conducting element before welding, improve welding quality.Since the opening about 11 that accommodates runs through the leg 1 and the solder 200 be retained in elongated cantilever-shaped fixed feet 12, the solder 200 of melting can be with faster speed from receipts Hold in opening 11 and successfully flow down, be conducive to be welded in time, the weldering between conducting terminal 100 and conducting element can be improved Connect quality.Meanwhile the solder 200 of melting can be converged in first, second guide channel 31,32 without towards each It overflows and influences welding effect in direction.

As shown in Figure 1 to Figure 3, the solder 200 is set in block, and the solder 200 includes setting from its surface indentation Mounting hole 20, the fixed feet 12 can be inserted into and interfere and is fixed in the mounting hole 20.Meanwhile the solder 200 can be set It is set to cylindrical body, bullet or spherical.In the present embodiment, the solder 200 is substantially set in cuboid, the mounting hole 20 is front and rear through the solder 200, and the fixed feet 12 is front and rear through the solder 200 along the mounting hole 20, to realize Better fixed effect, the both ends of the mounting hole 20 include import department 201 and outlet portion 202, and the fixed feet 12 is from described Import department 201 penetrates in the mounting hole 20 and is pierced by the mounting hole 20 from the outlet portion 202, from figure 3, it can be seen that The width of the import department 201 is bigger than 202 width of outlet portion, sets larger import department 201 that there is certain guiding to make With being conducive to successfully install the solder 200 to the fixed feet 12.

In summary, the solder 200 in the utility model, which is inserted in the fixed feet 12, can make the solder 200 steady Admittedly be fixed on conducting terminal 100 with convenience in transport, while the solder 200 is arranged at the collecting opening for running through leg 1 up and down It can smoothly be flowed between leg 1 and conducting element when it is heated in 11, to obtain preferable welding effect.

The foregoing is merely some embodiments of the utility model, the embodiment being not all of, the common skill in this field Art personnel are by reading the utility model specification and any equivalent variation taken technical solutions of the utility model The claim of the utility model is covered.
