Refer to shown in Fig. 1, and contrast Fig. 2, Fig. 3 and Fig. 4 simultaneously, the invention provides a kind of sandwiched method of solder part and solder terminal, comprise following steps:
There is provided a solder terminal 10, solder terminal 10 has one first and faces face 11,1 second and face side, 12, two, face 13 and a bottom surface 14(step S101);
Two sides 13 recessed at least side recess 131(step S103 respectively of solder terminal 10);
Two sides 13 projection at least side protuberance 133(step S105 respectively of solder terminal 10);
One solder part 20 is provided, makes solder part 20 be located in bottom surface 14 and two side 13(step S107 of solder terminal 10);
Side extruding force F is bestowed, bottom surface 14 and two side 13(step S109 to make solder part 20 closely be coated on solder terminal 10) along two sides 13 of solder terminal 10 and bottom surface 14 butt welding materials and parts 20; And
Utilize side extruding force F and make solder part 20 be filled at least side recess 131, and form a clip portion 21, the convex inside of thrusting solder part 20 of protuberance 133, side simultaneously, side recess 131 is connected with interfering with each other property of solder part 20, to provide an interfering edge, and strengthen the fixing sandwiched structure (step S111) of solder part 20 on solder terminal 10.
Preferably, the side protuberance 133 of solder terminal 10 1 sides 13 can be two, also can form convex of side depressed part 1331 between two side protuberances 133 like this, convex of side depressed part 1331 also can provide another interfering edge, to strengthen the sandwiched structure of fixing solder part 20 on solder terminal 10 further.
In addition, side recess 131 and solder part 20 are each other also for interference capability is connected, side recess 131 also has recessed top, side 1311 and recessed limit 1312, side, recessed top, side 1311 and recessed both limits 1312, side can not be arranged in parallel to each other, especially the nearly recessed top of open end side 1311 of side recess 131 and recessed limit 1312, side distance each other, the recessed top of side recess 131 private side 1311 and recessed limit 1312, side distance each other can be less than, to reach the effect of interference, or by recessed top 1311, side, the bending slightly on recessed limit 1312, side itself, also the object that butt welding materials and parts 20 produce interference effect can be reached.
Preferably, the solder part 20 in the side recess 131 of step S111 can because of by the impact of side extruding force F, and causes the thickness of solder part 20 itself or clip portion 21 to be thicker than first facing face 11 and second and face thickness between face 12, hold, the sandwiched method of solder part of the present invention and solder terminal also can comprise a step S113(and scheme not show): face along first the clip portion 21 faced in the fore-and-aft direction offside recess 131 in face 12 in face 11 and second and bestow an extruding force F ', extruding force F ' makes clip portion 21 deformation, extend an extension 211, extension 211 partly coated first is faced face 11 and second and is faced face 12, extension 211 like this can face face 11 to first of solder terminal 10 further, second faces face 12 produces the effect of seizing on both sides by the arms, more guarantee that solder part 20 can not be faced face 11 and second along first and faces the fore-and-aft direction in face 12 and drop out outside solder terminal 10.
Again, as shown in Figure 7, the solder part 20 of above-mentioned steps S107 can be also multiple terminal connection parts 22 with the mode punching molding of material strip (or being called blanking) in advance, and described multiple terminal connection part 22 all extends from a material strip base portion 23, again solder terminal 10 is squeezed into terminal connection part 22 in advance, preferably, can as described in above step S111, then along solder terminal 10 two sides 13 and 14 pairs, bottom surface terminal connection part 22(or also can be described as solder part 20) bestow side extruding force F(figure do not show), with the bottom surface 14 and two sides 13 that make solder part 20 can be coated on solder terminal 10 more closely, make solder part 20 can more positively be filled at side recess 131 simultaneously, and form a clip portion 21.
Protuberance 133 also more positively convex inside of thrusting solder part 20 outside this, side like this protuberance 133 can provide an interfering edge further, to assist the fixed effect of solder part 20 on solder terminal 10.After completing the sandwiched of solder part 20 pairs of solder terminals 10, more then material strip base portion 23 is excised the sandwiched that can complete solder part 20 pairs of solder terminals 10.
From the above, side extruding force F institute role, comprise and can not yet be configured as terminal connection part 22 at solder part 20 and make solder part 20 be located in the power-assisted of solder terminal 10 as one, also can after solder part 20 be configured as terminal connection part 22, as the power-assisted of an assistant reinforcement sandwiched structure.
Refer to shown in Fig. 2, Fig. 3 and Fig. 4, the present invention separately provides a kind of solder part 20 and the sandwiched structure of solder terminal 10, comprises: solder terminal 10 and a solder part 20.
