[0031] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced without one or more of these details. In other instances, certain technical features well known in the art are not described to avoid confusion with the present invention.
[0032] The present application discloses an anti-mistake structure for the insulating film of an electric vehicle capacitor busbar. The structure makes it easy to distinguish multiple insulating films through staggered protrusion structures, thereby solving the problem of high probability of missing or wrong installation of insulating films when assembling multiple insulating films at the same place on the busbar in the prior art.
[0033] In the first embodiment, the insulating film foolproof structure of the electric vehicle capacitor busbar includes: a first insulating film 100 and a second insulating film 200.
[0034] The first insulating film 100 and the second insulating film 200 are arranged at the same position of the busbar, wherein the same position of the busbar means that the first insulating film 100 and the second insulating film 200 are stacked in the thickness direction of the busbar. Figure 3 and 4 As shown, the positioning portions 400 of the first insulating film 100 and the second insulating film 200 are stacked on one side of the busbar along the thickness direction.
[0035] The first insulating film 100 and the second insulating film 200 are provided with protruding structures 500 . The protruding structures 500 are staggered and extend a predetermined distance outward from the busbar.
[0036] like Figure 1 The first insulating film 100 and the second insulating film 200 include: a main body and a positioning portion 400, and a protruding structure 500 is provided on one side of the main body or the positioning portion 400. Figure 1 The protruding structures 500 of the first insulating film 100 and the second insulating film 200 are arranged on the same side of the positioning portion 400 away from the main body, as shown in FIG. Figure 2 and 3 The main bodies of the multiple insulating films are bent and arranged at the same position of the busbar.
[0037] In this embodiment, the positioning portions 400 of the first insulating film 100 and the second insulating film 200 are provided with positioning holes 600 .
[0038] When the first insulating film 100 and the second insulating film 200 are arranged at the same position of the busbar, the positioning holes 600 are coaxially matched, which can facilitate the positioning of the multiple insulating films.
[0039] In this embodiment, the side of the positioning portion 400 close to the main body is a structure with decreasing width, so that the positioning portion 400 can be easily cut off after installation.
[0040] In this embodiment, the width of the protruding structure 500 of the first insulating film 100 is smaller than the width of the first insulating film 100 , and the protruding structure 500 is extended along the left side of the positioning portion 400 of the first insulating film 100 .
[0041] The width of the protruding structure 500 of the second insulating film 200 is smaller than the width of the second insulating film 200 , and the protruding structure 500 is extended along the right side of the positioning portion 400 of the second insulating film 200 .
[0042] The left side of the first insulating film 100 is a protruding structure 500, and the right side is a notch structure; the right side of the second insulating film 200 is a protruding structure 500, and the left side is a notch structure. The protruding structure 500 and the notch structure of the first insulating film 100 and the second insulating film 200 are overlapped, so that the notch structure can be blocked during correct installation, and it can be better observed whether the insulating film is missing or installed in the wrong order.
[0043] In this embodiment, the protruding structures 500 have the same shape.
[0044] and / or the lengths of the protruding structures 500 are the same.
[0045] In the second embodiment, a third insulating film 300 is added on the basis of the first embodiment.
[0046] like Figure 1 The insulating film foolproof structure of the electric vehicle capacitor busbar shown includes: a first insulating film 100, a second insulating film 200 and a third insulating film 300.
[0047] The first insulating film 100, the second insulating film 200 and the third insulating film 300 are arranged at the same position of the busbar. Figure 3 and 4 The positioning portions 400 of the first insulating film 100 , the second insulating film 200 , and the third insulating film 300 are stacked on one side of the busbar along the thickness direction.
[0048] The third insulating film 300 is provided with a protruding structure 500 , and the protruding structures 500 of the first insulating film 100 , the second insulating film 200 and the third insulating film 300 are staggered. The protruding structure 500 can extend a predetermined distance from one side of the main body or the positioning part 400 to the outside of the busbar.
[0049] like Figure 1 The width of the protruding structure 500 of the first insulating film 100 is smaller than the width of the first insulating film 100 , and the protruding structure 500 is extended along the left side of the positioning portion 400 of the first insulating film 100 .
[0050] The width of the protruding structure 500 of the second insulating film 200 is smaller than the width of the second insulating film 200 , and the protruding structure 500 is extended along the right side of the positioning portion 400 of the second insulating film 200 .
[0051] The width of the protruding structure 500 of the third insulating film 300 is smaller than the width of the third insulating film 300 , and the protruding structure 500 extends along the middle of the positioning portion 400 of the third insulating film 300 .
[0052] like Figure 1 The third insulating film 300 shown in FIG. 1 also includes a main body portion and a positioning portion 400, so that the first insulating film 100, the second insulating film 200 and the third insulating film 300 are arranged as shown in FIG. Figure 1 As shown, the left side of the first insulating film 100 is a protruding structure 500 and the right side is a notch structure, so that the right side of the second insulating film 200 is a protruding structure 500 and the left side is a notch structure, so that the protruding structure 500 and the notch structure of the first insulating film 100, the second insulating film 200 and the third insulating film 300 overlap, and the notch structure can be blocked when properly installed, as shown in FIG. Figure 4The protruding structure 500 of the third insulating film 300 completely overlaps with the notch structure of the first insulating film 100 and the second insulating film 200. When correctly installed, there is no gap between the three protruding structures 500, which allows better observation of whether the insulating films are missing or installed in the wrong order.
[0053] like Figure 1 and 2 The protruding structures 500 of the first insulating film 100 , the second insulating film 200 , and the third insulating film 300 are rectangular structures of the same shape, and the protruding structures 500 have the same length.
[0054] In the third embodiment, the shape of the protruding structure 500 is changed based on the second embodiment.
[0055] The shapes of the protruding structures 500 of the first insulating film 100 , the second insulating film 200 and the third insulating film 300 are different.
[0056] The shape of the protruding structures 500 of the first insulating film 100, the second insulating film 200 and the third insulating film 300 can be one of a rectangle, a triangle, a trapezoid and a fan, and the shapes of the protruding structures 500 of the first insulating film 100, the second insulating film 200 and the third insulating film 300 are not repeated, and the positions of the three protruding structures 500 are staggered, so that the protruding structures 500 of the first insulating film 100, the second insulating film 200 and the third insulating film 300 are easier to distinguish in terms of shape and position.
[0057] In a preferred embodiment, the shape of the protrusion structure 500 of the first insulating film 100 is a rectangle.
[0058] The shape of the protrusion structure 500 of the second insulating film 200 is a triangle.
[0059] The shape of the protrusion structure 500 of the third insulating film 300 is a fan shape.
[0060] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes may be made to it in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims.
