[0025] The following are specific embodiments of the present utility model and in combination with the accompanying drawings, the technical solutions of the present utility model are further described, but the present utility model is not limited to these embodiments.
[0026] As Figures 1 to 4 、Combined with Figure 6 shown, a positioning structure for soldering a copper strip to a signal terminal, which includes a first connection part 1 and a second connection part 2. The first connection part 1 includes a plurality of non-connected split bases 1′, and a corresponding number of signal terminals 101 are connected to each split base 1′. The signal terminals 101 include two types, namely a first terminal 1011 and a second terminal 1012. A plurality of first positioning holes 11 are provided on the first connection part 1 (split base 1′). The second connection part 2 is used to connect the copper strip 102, and a plurality of second positioning holes 211 are provided on the second connection part 2. In order to realize that a plurality of copper sheets 1021 on the copper strip 102 respectively abut against and are soldered to the first terminals 1011 in the signal terminals 101, a positioning fixture 3 is further included. The positioning fixture 3 at least includes a bottom plate 31 and a plurality of positioning posts 32 provided at the upper end of the bottom plate 31. The first positioning holes 11 and the second positioning holes 211 are sequentially sleeved on the positioning posts 32 at least so that the copper sheets 1021 on the copper strip 102 abut against the first terminals 1011 on the signal terminals 101.
[0027] In the present utility model, first, a plurality of split bases 1' and the signal terminals connected thereto are sequentially sleeved on the positioning posts 32 on the positioning fixture 3 through the first positioning holes 11, ensuring the stable and accurate positions of the first connecting portion 1 and the signal terminal 101. Then, the second connecting portion 2 and the copper strip 102 connected thereto are sleeved on the positioning posts 32 through the second positioning holes 211, and at least ensure that the plurality of copper sheets 1021 on the copper strip 102 are respectively in stable contact with the first terminals 1011. Then, the welding of the two is carried out to achieve the stable connection between the copper strip and the corresponding terminals, which can ensure the accuracy and stability of the connection; and due to the limitation and positioning of the copper strip 102, the consistency of the positions of the copper sheets 1021 on the first terminals 1011 can also be achieved.
[0028] In the present utility model, through the first connecting portion 1 and the first positioning hole 11 thereon, the second connecting portion 2 and the second positioning hole 211 thereon, and the positioning fixture 3 for positioning, the accurate and stable positioning of the copper strip 102 (a plurality of copper sheets 1021) and the first terminals 1011 can be achieved, which helps to ensure the quality of welding and can ensure the consistency of the positions of the copper sheets 1021 on different first terminals 1011.
[0029] Furthermore, to ensure the structural stability during the overall welding of the split base 1' and the signal terminal 101 of the integral structure, and the second connecting portion 2 and the copper strip 102 of the integral structure, when the copper strip 102 (copper sheet 1021) is in contact with the signal terminal 101, the second connection 2 abuts at least partially on the first connecting portion 1.
[0030] Furthermore, the second connecting portion 2 includes a transverse plate 21 and a connecting plate 22. One ends of a pair of connecting plates 22 are respectively connected to the copper strip 102, and the other ends are respectively connected to the transverse plate 21 through adjusting plates 21'. The lower end surface of the transverse plate 21 is flush with the lower end surface of the copper sheet 1021 and abuts on the upper end of the first connecting portion 1. By providing the adjusting plates 21', on the one hand, the connecting plates 22 can be extended outward to ensure the length requirement of the copper strip 102, and on the other hand, since the connecting plates 22 are connected to the copper strip 102, but the copper sheet 1021 is bent downward to abut on the first terminal 1011, the height of the transverse plate 21 is lowered compared with the connecting plates 22 through the adjusting plates 21' so that the lower end surface of the transverse plate 21 can abut on the first connecting portion 1.
[0031] Second positioning holes 211 are provided on both the transverse plate 21 and the connecting plate 22, which can ensure the accuracy and stability of the installation of the second connecting portion 2 on the positioning posts 32.
[0032] Preferably, the thickness of the transverse plate 21, the thickness of the adjusting plate 21', and the thickness of the connecting plate 22 are all equal, and the adjusting plate 21' reduces the height position of the transverse plate 21 through its L-shaped structure.
[0033] In addition, a first indentation 100 is provided between the first connecting portion 1 and the signal terminal 101, and a second indentation 200 is provided between the second connecting portion 2 and the copper strip 102. After the copper strip 102 is welded to the signal terminal 101 and then wrapped and fixed by the subsequent injection molded part, the first connecting portion 1 can be easily separated from the signal terminal 101 and the second connecting portion 2 can be easily separated from the copper strip 102 by bending or cutting at the indentation.
[0034] Combined with Figure 5 As shown, based on the above settings, the structure of the positioning post 32 is specifically as follows: it includes a bearing post 321 and a top post 322. The bearing post 321 is arranged on the bottom plate 31, and the top post 322 is arranged on the bearing post 321. A support platform 320 is formed between the two. The first positioning hole 11 and the second positioning hole 211 are sleeved on the top post 322, and the lower end of the first connecting portion 1 abuts against the support platform 320 to maintain the support stability of the first connecting portion 1 and the second connecting portion 2. In addition, an auxiliary positioning post 33 for cooperating with the through hole 1020 on the copper strip 102 can be arranged on the bottom plate 31, that is, the auxiliary positioning post 33 is embedded in the through hole 1020 to further ensure the accurate position of the copper strip 102, so as to ensure the consistency of the position of the copper sheet 1021 on the corresponding first terminal 1011.
[0035] The upper ends of the positioning post 32 and the auxiliary positioning post 33 are respectively provided with guiding cut surfaces, which are convenient for extending into the first positioning hole 11 and the second positioning hole 211, and the through hole 30.
[0036] Furthermore, a support area 30 for supporting the signal terminal 101 can be arranged on the bottom plate 31. By supporting one side of the signal terminal 101 through the support area 30 and supporting the first connecting portion 1 connected to the signal terminal 101 through the support platform 320, the overall horizontal state can be ensured.
[0037] In addition, a pressing member can be provided. After the first connecting portion 1 and the second connecting portion 2 are both sleeved on the positioning post 32, the second connecting portion 2 and the first connecting portion 1 are fixedly installed by installing the pressing member on the positioning post 32. Even if the position is moved or rotated, it will not shift, which can ensure the installation stability.
[0038] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
