[0022] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0023] In the prior art, in order to meet the requirement of applying torque to the threaded copper column, the threaded copper column is usually directly welded to the copper plate. However, this method has some defects. First, the threaded copper column after welding is difficult to remove from the copper plate, and once a threaded copper column on the copper plate is damaged, the entire copper plate may be scrapped, resulting in increased cost. Second, direct welding may cause thermal deformation of the copper plate, thereby increasing the complexity of operation.

[0024] Embodiment one

[0025] Therefore, in order to solve the above problems, reduce the cost, and improve the convenience of disassembling the threaded copper column, the utility model discloses a copper plate threaded copper column without welding, which comprises a bottom plate 1, a copper column 2 and a copper sleeve 3. Figures 1-4 The surface of the bottom plate 1 is provided with a clamping groove 8, the copper column 2 is provided with a limiting block 4, one end of the limiting block 4 away from the copper column 2 is provided with a threaded column 5, wherein the limiting block 4 is matched with the clamping groove 8, and the limiting block 4 is clamped in the inside of the clamping groove 8, the threaded column 5 passes through the clamping groove 8 and penetrates the bottom plate 1, and the copper sleeve 3 is sleeved on one end of the threaded column 5 penetrating the bottom plate 1.

[0026] In this embodiment, when installing the threaded copper column, the installer can pass the threaded column 5 on the copper column 2 through the clamping groove 8 on the bottom plate 1 until the limiting block 4 is butted into the clamping groove 8, and then uses the copper sleeve 3 to sleeve the threaded column 5, so as to fix the copper column 2 on the bottom plate 1, wherein due to the cooperation of the limiting block 4 and the clamping groove 8, the copper column 2 and the threaded column 5 will not rotate on the bottom plate 1, and by rotating the copper sleeve 3 into the threaded column 5 until the copper sleeve 3 is attached to the bottom plate 1, the entire threaded copper column is fixed on the bottom plate 1.

[0027] Through the above structure, the threaded copper column can be fixed on the bottom plate 1 without using welding, thereby avoiding the deformation of the bottom plate 1 caused by heat due to welding. In addition, the user can remove the fixation of the threaded copper column and the bottom plate 1 by rotating the copper sleeve 3 in the opposite direction, and then pull out the copper column 2 and the threaded column 5 from the clamping groove 8, achieving the purpose of convenient replacement of the threaded copper column, thereby improving the convenience of replacing the damaged threaded copper column.

[0028] Further, as a preferred technical solution, the clamping groove 8 and the limiting block 4 are both of a waist-shaped structure, the two ends of the waist-shaped structure are relatively smooth, which helps to reduce the friction between the limiting block 4 and the clamping groove 8 while limiting the threaded copper column, thereby improving the durability of the limiting structure.

[0029] Embodiment two

[0030] On the basis of embodiment one, in order to avoid the limiting block 4 being taken out of the clamping groove 8 at the same time when the threaded column 5 passes through the clamping groove 8, refer to Figure 4The utility model also includes the baffle 9 for preventing the limiting block 4 to pass through the clamping slot 8, specifically, the inside of clamping slot 8 is equipped with baffle 9, wherein, baffle 9 is equipped with the one end of threaded column 5 of limiting block 4 and is in contact.

[0031] In the embodiment, the baffle 9 plays a limiting role. When the limiting block 4 is inserted into the clamping slot 8, the baffle 9 can prevent the limiting block 4 from moving excessively in the clamping slot 8, ensuring that the installation position of the copper column 2 on the bottom plate 1 is more accurate and stable, and effectively preventing the copper column 2 from being displaced due to external forces and other factors during installation.

[0032] Further, in order to further improve the installation accuracy of the threaded copper column, the baffle 9 is provided with a limiting hole 10, wherein the limiting hole 10 is matched with the threaded column 5, and the limiting hole 10 is arranged around the threaded column 5. In the specific embodiment, when the user installs the threaded copper column, the threaded column 5 is first aligned and passed through the limiting hole 10, and then the copper column 2 is continuously pushed until the limiting block 4 is in contact with the baffle 9. At this time, because the threaded column 5 passes through the limiting hole 10, the limiting hole 10 can further position and constrain the threaded column 5, making the threaded column 5 more stable in the vertical direction and preventing it from shaking or shifting.

[0033] Example Three

[0034] Based on example one, in order to smoothly fix the threaded copper column, referring to Figure 3 The utility model also includes a sleeve ring 7, specifically, the copper sleeve 3 is provided with a sleeve ring 7 matched with the threaded column 5, wherein the copper sleeve 3 is used for fixing the copper column 2.

[0035] In the embodiment, the inner wall of the sleeve ring 7 is provided with threads matched with the threaded column 5. When installing the copper sleeve 3, the sleeve ring 7 is aligned with the threaded column 5 and screwed in. As the copper sleeve 3 continues to screw in, the threads between the sleeve ring 7 and the threaded column 5 interlock, the friction force gradually increases, tightly holding the threaded column 5, and thus stably fixing the copper column 2 on the bottom plate 1. Therefore, through the thread cooperation between the sleeve ring 7 and the threaded column 5, the copper column 2 can be kept stable, improving the reliability of electrical connection. At the same time, compared with other complex fixing methods, this structure is simple and easy to operate, and the installation personnel can quickly complete the installation and disassembly work, improving the work efficiency and reducing the maintenance cost.

[0036] Example Four

[0037] Based on example one, in order to smoothly connect electronic components to the threaded copper column, referring to Figure 2 The utility model also includes a threaded hole 6 for connecting electronic components, specifically, the threaded column 5 is provided with a threaded hole 6 away from the limiting block 4, and the threaded hole 6 extends along the length direction of the threaded column 5.

[0038] In actual use scenarios, when other components need to be connected to the threaded copper column, appropriate bolts or screws can be selected according to the structure and connection requirements of the components and connected with the screw hole 6. Thus, the application range of the welding-free copper plate threaded copper column is expanded, making it applicable to different types of connection requirements.

[0039] In addition, in combination with the easy-to-replace feature of the welding-free copper plate threaded copper column, the operator can replace the threaded column 5 with different hole diameters of the screw hole 6 according to different electronic component requirements, further improving the expandability and versatility of the present application.

[0040] Example five

[0041] On the basis of example one, in order to improve the structural integrity and conductivity of the copper column 2 and the limiting block 4, the copper column 2 and the limiting block 4 are integrally formed, and the copper column 2 and the limiting block 4 are both made of pure copper material.

[0042] In this embodiment, the integrally formed structure eliminates the connection gap or weak link between the copper column 2 and the limiting block 4. When subjected to external force or torque, stress can be evenly distributed throughout the structure, greatly improving the overall strength and stability of the structure. For example, when external force acts on the copper column 2, the integrally formed structure can effectively transmit the external force to the entire structure, avoiding damage due to weak connection parts.

[0043] At the same time, the selection of pure copper material ensures good electrical conductivity.

[0044] Example six

[0045] On the basis of any one of example one and example two, in order to facilitate the operator to install and disassemble the copper sleeve 3, the outer side wall of the copper sleeve 3 is provided with anti-slip lines.

[0046] In this embodiment, when installing the copper sleeve 3, the operator holds the copper sleeve 3 with his hand, and the anti-slip lines increase the friction between the hand and the copper sleeve 3. This makes it easier for the operator to tighten the copper sleeve 3 on the threaded column 5. Similarly, when disassembling the copper sleeve 3, the anti-slip lines also help the operator to loosen the copper sleeve 3 more easily.

[0047] In summary, in combination with examples one to six, the working steps of the welding-free copper plate threaded copper column are as follows:

[0048] First, the installer selects the appropriate size of the welding-free copper plate threaded copper column according to the actual requirements, and checks whether all components are intact.

[0049] Subsequently, the installation operation is performed. The threaded column 5 on the copper column 2 is aligned with the clamping groove 8 on the bottom plate 1 and passes through, in the process, the limiting block 4 is ensured to smoothly enter along the clamping groove 8, since the clamping groove 8 and the limiting block 4 are waist-shaped structures, the position needs to be found according to the special shape and the angle needs to be adjusted appropriately. After the threaded column 5 passes through the clamping groove 8, the copper column 2 is continuously pushed to make the limiting block 4 abut against the baffle 9 inside the clamping groove 8, at this time, if there is a limiting hole 10 on the baffle 9, the threaded column 5 needs to be ensured to accurately pass through the limiting hole 10, so as to realize further positioning of the threaded column 5 in the vertical direction. Then, the copper sleeve 3 is sleeved on one end of the threaded column 5 penetrating through the bottom plate 1 through the sleeve ring 7, the copper sleeve 3 is tightened, the threaded column 5 is fixed on the bottom plate 1 by the threaded cooperation of the sleeve ring 7 and the threaded column 5 and the clamping force of the copper sleeve 3 on the copper column 2, and in the tightening process, the operator can exert force better by means of the anti-skid lines on the outside of the copper sleeve 3.

[0050] Finally, when external electronic components or other components are needed, appropriate bolts or screws are selected according to the component structure and connection requirements, and the bolts or screws are connected through the threaded hole 6 at one end of the threaded column 5. In the process of using the equipment, if the threaded copper column is damaged and needs to be replaced, the operator first reversely rotates the copper sleeve 3 to loosen it and take it down, then pulls out the damaged copper column 2 and the threaded column 5 from the clamping groove 8, replaces a new threaded copper column, and re-installs according to the above installation steps. During the whole process, the copper column 2 and the limiting block 4 which are integrally formed and made of pure copper material ensure the structural strength and good electrical conductivity, and ensure the normal operation of the equipment.

[0051] Therefore, compared with the traditional welding method, one damaged threaded copper column may need to replace the entire circuit board, which is high in cost and complex in operation; the welding-free structure of the utility model can easily replace the damaged threaded copper column, save the cost and maintenance time, and improve the convenience and economy of equipment maintenance. At the same time, the cooperation between the components of the structure is tight, which ensures the stability of the threaded copper column in the use process and ensures the reliable electrical connection, which is helpful for the normal operation of the equipment.

[0052] The embodiments in the specification are described in a progressive manner, and each embodiment focuses on the difference from other embodiments. The same or similar parts between the embodiments can be referred to each other.

[0053] The above description of the disclosed embodiments enables a person skilled in the art to implement or use the utility model.
