This means that each model of lamp needs to have at least three versions of the above. This not only requires differentiation during the production process (classification manufacturing), but also requires strict differentiation during lamp storage, which puts a lot of pressure on inventory management. Utility Model Content

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] Example 1

[0034] Combine Figures 1 to 8 , schematically shows the multi-purpose connection structure of the present invention, including a base plate 10. In this embodiment, the base plate 10 is in the shape of a flat plate.

[0035] like Figure 1A plurality of annular process grooves 20 are provided on the substrate 10. By knocking the substrate 10 on one side of the corresponding process groove 20 with a hand or an existing tool, the process groove 20 can be broken, and a through hole 40 is formed on the substrate 10. The through holes 40 formed by knocking and breaking different process grooves 20 correspond to different controller interface holes. The inner wall surface of one of the process grooves 20 has a limited rotation plane 21, which is used to cooperate with the existing ZHAGA base 30. The other process groove 20 is annular and is used to cooperate with the existing NEMA base 30.

[0036] like Figure 2 and Figure 3 The cross-section of the bottom of the process groove 20 is set at an angle. The angle 26 of the bottom of the process groove 20 is a stress concentration area. The stress concentration area is more likely to crack and break after being struck. Therefore, the bottom of the process groove 20 of this structure is used to induce fracture, making it easier for the process groove 20 to crack and break after being struck, which is convenient for installation and maintenance personnel to quickly open holes on site and improve assembly efficiency.

[0037] Based on the above structure, only one multi-purpose connection structure needs to be managed during the production process or storage. In actual application, holes are opened according to the actual controller access requirements, so that the multi-purpose connection structure can adapt to different controller docking bases 30. For example, when the controller does not need to be connected, no process groove 20 is knocked or damaged, and the substrate 10 is kept intact. Figure 6 When the ZHAGA base 30 needs to be connected, the inner side of the process groove 20 with the rotation limiting plane 21 is knocked so that the substrate 10 material inside the process groove 20 falls off to form a through hole 40, and the ZHAGA base 30 can be inserted into the through hole 40. Figure 7 When the NEMA base 30 needs to be connected, the inner side of the process groove 20 that does not have a rotation limiting plane 21 and is annular is struck, so that the substrate 10 material inside the process groove 20 falls off to form a through hole 40, and the NEMA base 30 can be inserted into the through hole 40. Figure 8 .

[0038] Multiple process grooves 20 can be nested with each other, such as a process groove 20 with a larger diameter is arranged around a process groove 20 with a smaller diameter. Multiple process grooves 20 can also be arranged in parallel, such as multiple annular process grooves 20 are arranged in sequence on the substrate 10, both of which can realize a single multi-purpose connection structure to adapt to a variety of different controller docking requirements.

[0039] Specifically, the substrate 10 is preferably made of aluminum, specifically die-cast aluminum, and the substrate 10 and the process groove 20 provided thereon are an integrally formed structure, so as to simplify the production process of the multi-purpose connection structure and make it possible to mass-produce it. Figure 3 The depth of the process groove 20 is greater than 1 / 2 of the thickness of the substrate 10. This makes it easier for the process groove 20 to break after being struck to form the through hole 40 and can reduce the burr phenomenon on the wall of the through hole 40. It should be noted that the depth direction of the process groove 20 is parallel to the normal direction of the substrate 10.

[0040] The process groove 20 has a first inner wall 24 and a second inner wall 25. The first inner wall 24 and the second inner wall 25 are arranged opposite each other, and one side of the first inner wall 24 is connected to the other side of the second inner wall 25, resulting in a V-shaped cross-section of the process groove 20. With this structure, the process groove 20 has a simple shape and can form an angle 26 between the first inner wall 24 and the second inner wall 25. Stress concentrates at the angle 26, making the angle 26 more susceptible to fracture after being struck. The generatrix of the first inner wall 24 is parallel to the normal of the substrate 10. If the process groove 20 has a rotation limiting plane 21, the rotation limiting plane 21 is located on the first inner wall 24.

[0041] The busbar of the first inner wall 24 is preferably parallel to the normal of the substrate 10, which has at least two advantages. One is that after being struck, stress is concentrated and broken at the angle 26, resulting in tearing at the connection between the first inner wall 24 and the second inner wall 25. The substrate 10 material on the inner side of the process groove 20 falls off and forms a through hole 40, that is, the first inner wall 24 and the second inner wall 25 are separated from each other, and the inner wall surface of the through hole 40 is the first inner wall 24. It is precisely because the busbar of the first inner wall 24 is parallel to the normal of the substrate 10 that the busbar of the inner wall of the through hole 40 is also parallel to the normal of the substrate 10, avoiding the formation of a cone or an inclined surface on the inner wall of the through hole 40. Secondly, the first inner wall 24 can be provided with a rotation-limiting plane 21. This plane 21 is intended to mate with the ZHAGA base 30. The rotation-limiting plane 21 aligns with a plane on the ZHAGA base 30 to limit relative rotation between the ZHAGA base 30 and the through-hole 40 formed by hammering. The rotation-limiting plane 21 must be parallel to the normal of the substrate 10. In other optional embodiments, the generatrix of the first inner wall 24 can also be arranged at an angle relative to the normal of the substrate 10.

[0042] In order to concentrate stress more at the angle 26 between the first inner wall 24 and the second inner wall 25 , the angle 26 is an acute angle.

[0043] In addition, if Figure 6A plurality of connection holes 13 are provided on the substrate 10, and the connection holes 13 are located on the side of the process groove 20. When there is no need to access the controller, the substrate 10 is kept intact, and the multi-purpose connection structure can be connected to other supporting structures (such as lamp poles) through the above-mentioned plurality of connection holes 13.

[0044] Example 2

[0045] Combine Figures 1 to 3 As shown, the difference between this embodiment and Example 1 is that, among the multiple process grooves 20, the process grooves 20 with larger projected areas on the substrate 10 are arranged around the process grooves 20 with smaller projected areas on the substrate 10. That is, the process grooves 20 with larger diameters surround the process grooves 20 with smaller diameters. Of course, this applies to process grooves 20 in the shape of circular rings. If the process grooves 20 are in the shape of square rings, the process grooves 20 with larger projected areas on the substrate 10 are arranged around the process grooves 20 with smaller projected areas. This arrangement of multiple process grooves 20 can reduce the area occupied by the multiple process grooves 20 on the substrate 10, allowing this structure to be installed on substrates 10 with smaller areas, thus expanding its applicability.

[0046] Furthermore, one of the process grooves 20 is referred to as the first groove 22, and the other process groove 20 is referred to as the second groove 23. The inner wall surface of the first groove 22 has a limited rotation plane 21, and the second groove 23 is arranged around the first groove 22. The through hole 40 formed by the first groove 22 breaking after being struck is preferably connected to the ZHAGA base 30, and the through hole 40 formed by the second groove 23 breaking after being struck is preferably connected to the NEMA base 30.

[0047] Example 3

[0048] like Figures 2 to 5 As shown, the difference between this embodiment and embodiment 2 is that the multi-purpose connection structure of this embodiment includes a base plate 10. In this embodiment, the base plate 10 is in a flat plate shape and is provided with a first groove 22 and a second groove 23. The base plate 10 has a front surface 11 and a back surface 12. The first groove 22 is provided on the front surface 11 of the base plate 10, and the second groove 23 is provided on the back surface 12 of the base plate 10.

[0049] like Figure 2 and Figure 3The first groove 22 and the second groove 23 are arranged on the two surfaces of the substrate 10. Firstly, it is convenient for the installation and maintenance personnel to quickly distinguish the first groove 22 and the second groove 23, which plays a role in quick identification. Secondly, the fracture striking directions of the first groove 22 and the second groove 23 can be distinguished. For example, applying force to strike the inner side of the first groove 22 on the front side 11 of the substrate 10 can cause the first groove 22 to break and form a corresponding through hole 40. Striking the inner side of the second groove 23 on the back side 12 of the substrate 10 can cause the second groove 23 to break and form a corresponding through hole 40. In this way, it is avoided that the first groove 22 and the second groove 23 are broken at the same time when striking.

[0050] Example 4

[0051] The difference between this embodiment and embodiment 1 is that the cross-section of the substrate 10 extends in a curved shape, which causes the surface of the substrate 10 to be a curved surface, and the busbars of an inner side wall in each process groove 20 are parallel to each other. For example, there are two process grooves 20, and the busbars of an inner side wall of one process groove 20 are parallel to the busbars of an inner side wall of another process groove 20. In this way, no matter which process groove 20 is knocked and the through hole 40 is formed, the busbars of the inner wall surface of the formed through hole 40 are parallel to each other, and different types of controller docking bases 30 can be inserted into the corresponding through hole 40 in the same direction.

[0052] Example 5

[0053] This embodiment provides a lamp, including a lamp housing and the above-mentioned multi-purpose connecting structure. The substrate 10 is arranged on the lamp housing. In some optional embodiments, the lamp housing and the substrate 10 are an integrally formed structure.

[0054] To sum up, the substrate 10 is provided with a plurality of annular process grooves 20, and the cross-section of the bottom of the process groove 20 is set at an angle 26. The bottom of the process groove 20 is used to induce fracture. Knocking the corresponding process groove 20 can cause the process groove 20 to break and form a through hole 40. The through holes 40 formed by knocking and breaking different process grooves 20 correspond to different controller interface holes. The inner wall of one of the process grooves 20 has a rotation limiting plane 21 to adapt to the corresponding controller interface. This structure can realize a single structure to adapt to a variety of different application scenarios and user needs, reducing the difficulty of production and inventory management.
