[0026] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.
[0027] Please refer to Figures 1 to 7 The utility model provides a grounding protection device, which includes a module shell 1 and a grounding spring 2 fixed on the module shell 1, the module shell 1 is provided with a plurality of limit blocks and a limit groove 11, and the grounding spring 2 is provided with a bending portion 21; wherein the plurality of limit blocks are at least used to abut against two adjacent side edges of the grounding spring 2, and the bending portion 21 is arranged in the limit groove 11.
[0028] From the above description, it can be seen that the beneficial effect of the utility model is that the module shell 1 is set on the grounding spring sheet 2, and a plurality of limit blocks are provided on the module shell 1, and the plurality of limit blocks are used to abut against two adjacent sides of the grounding spring sheet 2 at least, so as to limit the grounding spring sheet 2 in the horizontal direction. On this basis, a limit groove 11 is provided on the module shell 1, and a bending portion 21 is correspondingly provided on the grounding spring sheet 2, and the bending portion 21 is provided in the limit groove 11, and the bending portion 21 can be clamped in the limit groove 11 through the limit groove 11, thereby fixing the grounding spring sheet 2 and the module shell 1 together, playing a fixing role (such as in the height direction), and preventing the grounding spring sheet 2 from falling off. In summary, the grounding protection device of the utility model can fix the grounding spring sheet 2 in multiple directions, increase the stability of the grounding spring sheet 2, avoid the grounding spring sheet 2 from rotating and falling off, and does not need to add additional processes, thereby reducing costs.
[0029] Furthermore, in the grounding protection device described in the utility model, the plurality of limit blocks include at least a first limit block 12 and a second limit block 13, the first limit block 12 extends along a first direction, and the second limit block 13 extends along a second direction; wherein, the first direction is the horizontal length direction of the module shell 1, and the second direction is the horizontal width direction of the module shell 1.
[0030] In the above technical solution of the utility model, a first limit block 12 extending in the horizontal length direction and a second limit block 13 extending in the horizontal width direction are provided on the module housing 1. By placing the first limit block 12 and the second limit block 13 against the adjacent sides of the grounding spring sheet 2 extending in the first direction and in the second direction, respectively, the grounding spring sheet 2 can be limited in the horizontal length direction and the horizontal width direction, so that the module housing 1 can fix the grounding spring sheet 2 in the horizontal direction.
[0031] Further, in the grounding protection device of the utility model, the limit groove 11 is an inclined groove with an opening facing upward, and the groove depth of the inclined groove gradually increases along the second direction. In addition, it should be noted that the angle between the extension direction of the groove bottom and the extension direction of the groove wall of the inclined groove is 90 degrees.
[0032] In the above technical solution of the utility model, the limiting groove 11 is an inclined groove with an opening facing upward, and the bottom of the inclined groove is an inclined surface. When the bending portion 21 is arranged on the inclined surface of the groove bottom, the surface of the bending portion 21 will form a close contact with the groove bottom of the inclined groove. Due to the design of the inclined surface and the friction force generated by it, a wedge-shaped self-locking state can be formed between the module housing 1 and the grounding spring sheet 2, achieving a self-locking effect, thereby fixing the grounding spring sheet 2 and preventing the grounding spring sheet 2 from falling off. In actual use, when a force acts on the grounding spring sheet 2 (i.e., the bending portion 21), its effective component force will be less than the maximum friction force in the same direction caused by the inclined surface design. Therefore, no matter how the force increases, the bending portion 21 will not move in a direction perpendicular to the inclined surface, thereby achieving self-locking.
[0033] Furthermore, in the grounding protection device described in the present invention, the grounding spring piece 2 is in a U-shape, and the module housing 1 is fixed in the U-shaped cavity formed by the grounding spring piece 2 .
[0034] In the above technical solution of the present invention, the shape of the grounding spring clip 2 is set to be U-shaped, and the module shell 1 is clamped in the U-shaped cavity formed by the grounding spring clip 2. On the one hand, the grounding spring clip 2 and the module shell 1 can be fixed in the vertical height direction. On the other hand, since the open end portion of the U-shaped cavity formed by the grounding spring clip 2 abuts against the first limit block 12, in the second direction, the grounding spring clip 2 can only move in the direction away from the first limit block 12. Since the bending portion 21 on the grounding spring clip 2 is set in the inclined groove, it will prevent the grounding spring clip 2 from moving in the direction away from the first limit block 12, so that in the second direction, the grounding spring clip 2 is fixed on the module shell 1 to prevent the grounding spring clip 2 from falling off.
[0035] Furthermore, in the grounding protection device described in the utility model, the grounding spring plate 2 includes a first connecting plate 22, a second connecting plate 23 and a third connecting plate 24 connected in sequence, wherein the first connecting plate 22 and the third connecting plate 24 are arranged in parallel, and the second connecting plate 23 is vertically connected to the first connecting plate 22 and the second connecting plate 23 respectively.
[0036] In the above technical solution of the present invention, by setting a first connecting plate 22, a second connecting plate 23 and a third connecting plate 24 connected in sequence, the shape of the grounding spring sheet 2 can be made into a U-shaped structure, thereby forming a U-shaped cavity, so that the module shell 1 can be fixed in the U-shaped cavity formed by the grounding spring sheet 2, thereby effectively fixing the grounding spring sheet 2 and improving the stability of the grounding spring sheet 2.
[0037] Furthermore, in the grounding protection device described in the present invention, the bottom surface of the module housing 1 is provided with a first recessed portion 14 recessed inwardly, and the third connecting plate 24 is embedded in the first recessed portion 14 .
[0038] In the above technical solution of the present invention, a first recessed portion 14 recessed inwardly is provided on the bottom surface of the module shell 1, and the third connecting plate 24 of the grounding spring piece 2 is arranged in the first recessed portion 14 to limit the third connecting plate in the horizontal direction, so that the grounding spring piece 2 can only move in the second direction away from the first limiting block 12 in the horizontal direction. Due to the arrangement of the above-mentioned inclined groove and the bending portion 21, the movement of the grounding spring piece 2 in the second direction can be prevented, so that the grounding spring piece 2 can be clamped in the horizontal direction, thereby improving the stability of the grounding spring piece 2 and avoiding the grounding spring piece 2 from rotating or falling off.
[0039] Furthermore, in the grounding protection device of the utility model, a first through hole 221 is provided on the first connecting plate 22, a second through hole 241 is provided on the third connecting plate 24, and a third through hole 15 is provided on the module shell; wherein, the first through hole 221, the second through hole 241 and the third through hole 15 are coaxially arranged, and the diameters of the first through hole 221 and the second through hole 241 are larger than those of the third through hole 15.
[0040] In the above technical solution of the utility model, the first connecting plate 22, the second connecting plate 23 and the module housing 1 are respectively provided with coaxial first through hole 221, second through hole 241 and third through hole 15. Since the first through hole 221, the second through hole 241 and the third through hole 15 are coaxially provided, the grounding spring piece 2 and the module housing 1 can form a channel, which can be used to set bolts, etc., so as to fix the grounding spring piece 2 and the module housing 1.
[0041] Furthermore, in the grounding protection device described in the utility model, a hollow portion 222 is provided on the first connecting plate 22 , and the bending portion 21 extends from a side edge of the hollow portion 222 and is located in the hollow portion 222 .
[0042] In the above technical solution of the utility model, the bending portion 21 is extended from one side of the hollow portion 222, so that the bending portion 21 can be arranged at the bottom of the inclined groove, thereby achieving a wedge-shaped self-locking state.
[0043] Furthermore, in the grounding protection device described in the utility model, a second recessed portion 223 recessed downward is provided on the upper surface of the first connecting plate 22, and the cross-section of the second recessed portion 223 in the vertical height direction perpendicular to the first connecting plate 22 gradually increases upward along the vertical height.
