Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive technology, and in particular to a combined anti-rotation grounding terminal structure. Background Technology
[0002] Existing grounding terminals in automotive wiring harnesses have a protective structure, but they can only be grounded individually. The assembly process is cumbersome, and multiple grounding points require multiple assembly steps, resulting in poor installation convenience and low production assembly efficiency. Multiple combined grounding points need to be welded onto the body / frame, which requires numerous welding fixtures and is therefore expensive.
[0003] Therefore, some designs for automotive wiring harness grounding terminals are modular structures, with terminal pieces stacked and fixed together, and adjacent terminal pieces positioned together by protrusions, resulting in poor positioning. For example, Chinese patent CN219487364U discloses an automotive wiring harness grounding structure and an automobile, which uses a plate-shaped grounding bracket and fixing bolts to fix the grounding terminal to the sheet metal structure of the vehicle body, and sets first and second positioning structures between the grounding bracket and the grounding terminal, as well as between the grounding terminals, so that the installation of the grounding terminal is not affected by the shape of the body sheet metal structure. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a combined anti-rotation grounding terminal structure to achieve a stable and reliable combined structure.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0006] This combined anti-rotation grounding terminal structure includes a grounding bolt, a bottom terminal grounding piece that is fixed in conjunction with the grounding bolt, and a set of upper terminal grounding pieces. The bottom terminal grounding piece has a pair of anti-rotation structures on its edge that are locked on both sides of the grounding bolt. Each upper terminal grounding piece has a boss and a limiting hole. The bottom terminal grounding piece has a protrusion for engaging with the limiting hole. Adjacent upper terminal grounding pieces are positioned by engaging with the boss and the limiting hole.
[0007] Further:
[0008] The anti-rotation structure is a bent structure that extends from the edge of the bottom terminal grounding plate.
[0009] Both the protrusions and bosses are sharp-angled protrusion structures.
[0010] The bottom terminal grounding plate has a folded hook structure on its edge, and the upper terminal grounding plate has a notch on its edge that can cooperate with the hook structure.
[0011] The hook structure on the bottom terminal grounding plate is a pair of hooks arranged opposite each other.
[0012] The upper terminal grounding piece has a side hook on its edge that matches the notch of the adjacent grounding piece.
[0013] The notch at the edge of the upper terminal grounding plate is an open arc-shaped groove structure.
[0014] Compared with the prior art, this utility model has the following advantages:
[0015] The combined anti-rotation grounding terminal structure is reasonably designed, and the combined grounding terminal has an anti-rotation structure; at the same time, it uses a layer-by-layer compaction and interlocking structural design, and the combined structure is stable and reliable; moreover, the structure is simple and easy to assemble.

[0024] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and through the description of the examples.
[0025] This combined anti-rotation grounding terminal structure includes a grounding bolt 8, a bottom terminal grounding plate that is fixed in conjunction with the grounding bolt, and a set of upper terminal grounding plates; such as Figure 1 and Figure 2As shown, the bottom terminal grounding piece is terminal grounding piece I1, and a set of upper terminal grounding pieces are terminal grounding piece II2, terminal grounding piece III3, terminal grounding piece IV4, terminal grounding piece V5, terminal grounding piece VI6 and terminal grounding piece VII7. All terminal grounding pieces are provided with a central through hole that mates with the grounding bolt 8, and each terminal grounding piece has a crimping part extending out, thereby forming a crimping area.
[0026] The bottom terminal grounding plate has a pair of anti-rotation structures that are locked on both sides of the grounding bolt. Each upper terminal grounding plate has a boss and a limiting hole 19. The bottom terminal grounding plate has a protrusion for engaging with the limiting hole. Adjacent upper terminal grounding plates are positioned by engaging with the boss and the limiting hole.
[0027] This utility model features a reasonably designed combined anti-rotation grounding terminal structure. The combined grounding terminal has an anti-rotation structure; at the same time, it utilizes a layered and interlocking structural design, making the combined structure stable and reliable; and it is simple in structure and easy to assemble.
[0028] like Figure 3 and Figure 4 As shown, the anti-rotation structure is a bent structure extending from the edge of the bottom terminal grounding plate. The anti-rotation structure is a pair of opposite structures, namely anti-rotation structure I9 and anti-rotation structure II10. The pair of bent structures are stuck on both sides of the end of the grounding bolt, thereby playing the anti-rotation function. It is achieved by utilizing its own structure, which is simple.
[0029] The protrusion 13 on the bottom terminal ground plate and the boss 18 on the upper terminal ground plate are both sharp-angled protrusion structures, which are reliable in positioning when matched with the limiting hole and are easy to position.
[0030] Furthermore, the bottom terminal grounding plate has a folded hook structure on its edge, and the upper terminal grounding plate has a notch on its edge that can cooperate with the hook structure; preferably, the hook structure on the bottom terminal grounding plate is a pair of hooks arranged opposite each other, namely hook I 11 and hook II 12.
[0031] The upper terminal grounding piece has a side hook on its edge that matches the notch of the adjacent grounding piece. The side hooks are also a pair that are arranged opposite each other, namely hook Ⅲ16 and hook Ⅳ17. The notch on the edge of the upper terminal grounding piece is an open arc-shaped groove structure.
[0032] When the components are assembled and fixed, a pair of anti-rotation structures on the bottom terminal grounding plate are positioned on both sides of the lap bolt. The protrusion on the bottom terminal grounding plate mates with the limiting hole on terminal grounding plate II. A pair of hooks on the bottom terminal grounding plate are positioned at a pair of notches on the side of terminal grounding plate II. Adjacent upper terminal grounding plates are positioned by matching bosses and limiting holes, and by side hooks and corresponding notches. The crimping parts of different terminal grounding plates are staggered, such as crimping area I14 and crimping area II15 being staggered. The combined structure is stable and reliable, and the structure is simple and easy to assemble.
[0033] The above description is only a preferred embodiment of the present utility model. The above technical features can be arbitrarily combined to form multiple embodiments of the present utility model.
[0034] The present invention has been described above with reference to the accompanying drawings.
