Summary of the Invention
Problems to be Solved by the Invention
[0004] By the way, when joining the end faces of a pair of bus bars, there are cases where the end faces cannot face each other due to deformation or dimensional errors of the bus bars. In this case, a jig is used for each bus bar to correct the deformation and dimensional errors, thereby making the end faces of each bus bar face each other and joining them by welding or the like to form a bus bar structure. However, such a method has problems in that it requires the installation of a jig and the labor of an operator, resulting in a high manufacturing cost of the bus bar structure.
[0005] The present invention has been made in view of the above circumstances, and an object thereof is to provide a bus bar structure and a bus bar that can reduce the manufacturing cost even when the bus bar has deformation or dimensional errors.
Means for Solving the Problems
[0006] In order to achieve the above-described object, the bus bar structure according to the present invention is characterized as follows. A busbar structure comprising a first busbar and a second busbar joined by abutting against each other in the width direction or length direction, The first busbar comprises a first busbar body and a first thin end portion that is thinner than the first busbar body. The first thin end is curved in the thickness direction, The first thin end of the first busbar and the end of the second busbar are joined together by abutting. It must be a busbar structure.
[0007] Furthermore, in order to achieve the aforementioned objectives, the bus bar according to the present invention has the following features. It comprises a busbar body and a thin end portion that is thinner than the busbar body, The aforementioned thin end is curved in the thickness direction, It's a bass guitar. [Effects of the Invention]
[0008] The busbar structure according to the present invention has the effect of reducing manufacturing costs even if deformation or dimensional errors occur in the busbar.
[0009] Furthermore, the busbar according to the present invention has the effect of lowering manufacturing costs even if deformation or dimensional errors occur in the busbar.
[0010] The present invention has been briefly described above. Furthermore, the details of the present invention will be further clarified by referring to the attached drawings and reading through the embodiments for carrying out the invention described below (hereinafter referred to as "embodiments"). [Brief explanation of the drawing]
[0011] [Figure 1] Figure 1 is a side view showing a busbar structure and busbar according to an embodiment of the present invention. It is a schematic plan view. [Figure 2] Figure 2 is a side view showing the state in which dimensional tolerances exist along the length direction between the busbars. [Figure 3]Figure 3 is a side view showing a state where dimensional tolerances exist between busbars along the thickness direction. [Modes for carrying out the invention]
[0012] <Embodiment> The busbar structure and busbars according to the embodiment of the present invention will be described below with reference to the drawings. As shown in Figure 1, the busbar structure 10 according to the embodiment of the present invention comprises two busbars 11 (first busbar) and busbar 12 (second busbar) that are joined together by abutting against each other in the width direction or length direction.
[0013] The busbars 11 and 12 each have a busbar body 13 (first busbar body) and a busbar body 14 (second busbar body) formed in a substantially strip shape with a predetermined thickness, and thin ends 15 (first thin end) and 16 (second thin end) provided at the longitudinal ends of the busbar bodies 13 and 14. The thin ends 15 and 16 are provided to be thinner than the thickness dimension T1 of the busbar bodies 13 and 14, or to have a thickness dimension T2 that is half of that thickness.
[0014] These thin ends 15 and 16 are curved in the thickness direction such that the convex arcuate surfaces 17 and 18 face away from the busbar bodies 13 and 14. In such a busbar structure 10, the thin ends 15 and 16 are abutted against each other so that the generatrixes of the arcuate surfaces 17 and 18 make line contact with each other, and the busbars 11 and 12 come into contact. In this state, the busbar structure 10 is obtained by joining the contact portion of the arcuate surfaces 17 and 18 by welding or other means.
[0015] As shown in Figure 2, if the busbars 11 and 12 of the busbar structure 10 have dimensional tolerances along the length direction, the thin ends 15 and 16 undergo further curvature deformation, thereby correcting the dimensional tolerances while maintaining line contact between the generatrixes of the arcuate surfaces 17 and 18.
[0016] Also, as shown in FIG. 3, when a dimensional tolerance along the thickness direction occurs in one or both of the busbars 11 and 12, the dimensional tolerance is corrected while maintaining the state where the generatrices of the arc surfaces 17 and 18 are in line contact with each other by changing the location of line contact.
[0017] <Effects of the Embodiment> As described above, according to the busbar structure 10 according to the embodiment of the present invention, the two busbars 11 and 12 are joined with the thin and thick end portions 15 and 16 curved in the thickness direction abutting against each other. Therefore, even if deformation or dimensional error occurs in the busbars 11 and 12, there is no need for a jig as in the prior art, and it is not necessary for an operator to take time and effort, and there is no problem of increasing the manufacturing cost of the busbar structure.
[0018] Furthermore, according to the busbar structure 10 according to the embodiment of the present invention, the thickness dimensions L2 of the thin and thick end portions 15 and 16 of the two busbars 11 and 12 are provided to be half of the thickness dimensions T1 of the busbar bodies 13 and 14. Therefore, the thin and thick end portions 15 and 16 can be easily curved, and even when dimensional tolerance occurs along the length direction of the busbars 11 and 12, the dimensional tolerance can be corrected by further curved deformation of the thin and thick end portions 15 and 16, thereby improving the manufacturing efficiency of the busbar structure 10.
[0019] And, according to the busbars 11 and 12 according to the embodiment of the present invention, the busbar bodies 13 and 14 and the thin and thick end portions 15 and 16 provided to be thinner and thicker than the busbar bodies 13 and 14 are provided, and the thin and thick end portions 15 and 16 are curved in the thickness direction. Therefore, even if deformation or dimensional error occurs in the busbars 11 and 12, there is no need for a jig as in the prior art, and it is not necessary for an operator to take time and effort, and there is no problem of increasing the manufacturing cost of the busbar structure 10.
[0020] <Other Forms> It should be noted that the present invention is not limited to the embodiments described above, and various modifications can be adopted within the scope of the present invention. For example, the present invention is not limited to the embodiments described above, and can be modified, improved, etc. as appropriate. Furthermore, the material, shape, dimensions, number, placement, etc. of each component in the embodiments described above are arbitrary and not limited as long as they can achieve the present invention.
[0021] For example, in the embodiment described above, the busbars 11 and 12 were each provided with thin ends 15 and 16, but the thin ends 15 and 16 may be provided on only one of the busbars 11 and 12, and such a form is also included in the present invention. Furthermore, in the embodiment described above, the thin ends 15 and 16 of the busbars 11 and 12 were formed in a symmetrical shape with respect to the joint, but the curvature direction of the thin ends 15 and 16 may be reversed, as long as the generatrixes of the arcuate surfaces 17 and 18 are in line contact with each other.
