Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a copper busbar fixing clamp. Background Technology

[0002] In the fields of vehicle manufacturing and electrical system installation, the secure fixing of flat, strip-shaped workpieces such as copper busbars and ribbon cables has always been a critical and challenging issue. These workpieces play a vital role in power transmission and signal transmission within the vehicle's electrical system, and the stability of their fixation directly affects the normal operation and safety of the system. However, during actual vehicle operation, due to the complex and varied road conditions, vehicles inevitably experience various vibrations and bumps. These external forces significantly impact vehicle components, especially flat, strip-shaped workpieces, which, due to their structural characteristics, are more prone to loosening, displacement, or even damage when subjected to vibrations and bumps.

[0003] If these components become loose or shifted, it will not only affect the stability and reliability of the vehicle's electrical system, leading to power transmission interruptions or abnormal signal transmission, thus affecting the normal operation of the vehicle, but in severe cases, it may also cause safety accidents, threatening the lives and property of passengers. Furthermore, damage to the components increases maintenance costs and replacement frequency, raising the overall cost of vehicle operation. Therefore, how to effectively fix flat, strip-shaped components so that they can withstand vibrations and bumps during vehicle operation without loosening, shifting, or being damaged has become a pressing technical problem to be solved in the fields of vehicle manufacturing and electrical system installation.

[0004] Therefore, we propose a copper busbar fixing clamp. Utility Model Content

[0005] Therefore, it is necessary to provide a copper busbar fixing fixture to address the technical problem that flat strip workpieces such as copper busbars and ribbon cables are prone to loosening, displacement, or even damage during vehicle operation due to vibration and bumps, which affects the stability and reliability of the vehicle's electrical system. This fixture can securely fix flat strip workpieces during vehicle operation, effectively absorb and disperse vibration energy, reduce the impact on the workpiece, ensure that the workpiece is always in the correct position, and improve the stability and reliability of the vehicle's electrical system.

[0006] This utility model provides a copper busbar fixing clamp, including a clamping part; the clamping part has a U-shaped base plate and side plates connected to both sides of the base plate; each of the two side plates has a first baffle plate inclined at a certain angle towards the base plate at its movable end; a support part for supporting the workpiece is provided on the end face of the base plate facing the side plates; a second baffle plate inclined towards the base plate is provided on the side of each of the two side plates near the support part, and the highest point of the second baffle plate is higher than the highest point of the support part. This clamp provides a stable placement and clamping space for the workpiece through the U-shaped base plate and the two side plates. The first and second baffle plates position and compress the workpiece from the thickness and width directions, respectively, ensuring the stability and accuracy of the workpiece during clamping. The support part provides uniform support force to the workpiece, further improving the reliability of clamping. This structural design enables the clamp to effectively cope with vibrations and bumps generated during vehicle operation, protecting the workpiece from damage and ensuring the normal operation of the vehicle's electrical system.

[0007] In other embodiments, the first baffle is formed by bending an extension of the side plate, with a bending angle α of 30°-60°. This method simplifies the manufacturing process and improves the overall strength of the fixture. Furthermore, by properly controlling the bending angle α, it can be ensured that the first baffle does not cause excessive damage to the workpiece while applying pressure, thus guaranteeing clamping stability and extending the workpiece's service life.

[0008] In other embodiments, the angle β between the second baffle and the side plate satisfies 120°≤β≤160°. By reasonably controlling the angle β between the second baffle and the side plate, it can be ensured that the second baffle can exert its optimal effect when pressing the workpiece. If the angle is too small, it will be difficult to press the workpiece down, causing the workpiece to be in a suspended state; if the angle is too large, the second baffle will easily lose its pressing effect. Therefore, the selection of this angle range is one of the key factors to ensure the clamping effect of the fixture.

[0009] In other embodiments, a clearance groove is provided on the side of the side plate near the first baffle, and the depth of the clearance groove is close to the thickness of the first baffle. The clearance groove solves the interference problem that may be encountered during workpiece placement. Since the workpiece and the side plate adopt an interference fit, without the clearance groove, the workpiece will not be able to smoothly enter the clamping part. The depth of the clearance groove is close to the thickness of the first baffle, ensuring that the workpiece can be automatically aligned during placement, thus improving production efficiency.

[0010] In other embodiments, the two side plates are provided with contact areas between the clearance groove and the second baffle, and the workpiece is interference-fitted between the two contact areas. The contact areas, as the parts where the side plates directly contact the workpiece, ensure stable clamping of the workpiece within the contact areas through the interference fit. This design not only improves clamping stability but also allows the fixture to adapt to workpieces of different widths and thicknesses, enhancing the fixture's versatility and flexibility.

[0011] In other embodiments, at least one of the side plates has a thinned section on its sidewall away from the contact area. This thinned section increases the flexibility of the side plate, allowing it to better adapt to changes in the shape and size of the workpiece. By thinning the side plate's wall thickness, its rigidity is reduced, increasing its deformation capacity under external forces. This design not only improves the contact effect between the fixture and the workpiece but also reduces the risk of workpiece damage due to excessive rigidity.

[0012] In other embodiments, the support includes horizontal and vertical ribs arranged in an H-shape. These ribs together form a stable support structure, effectively distributing the weight of the workpiece and the effects of external forces. This design improves the support effect, making the workpiece more stable and less prone to shaking or tilting during clamping. Simultaneously, the H-shaped structure also possesses a certain degree of elasticity and toughness, capable of absorbing and dispersing vibration energy to a certain extent, further protecting the workpiece from damage.

[0013] In other embodiments, a mating portion is also included, which is connected to the end face of the base plate away from the side plate. The mating portion facilitates the fixed connection of the clamping portion to other equipment or structures. Through the mating portion, the fixture can be easily installed on vehicles or other applications requiring workpiece fixation, improving the fixture's flexibility and versatility. Simultaneously, the design of the mating portion also considers the stability and reliability of the fixture, ensuring that loosening or detachment does not occur during the fixing process.

[0014] In other embodiments, the mating part and the clamping part are integrally formed, and the material is rubber, plastic, or metal. This integral design ensures a strong connection and overall strength between the mating part and the clamping part. Furthermore, the choice of rubber, plastic, or metal as the material allows for flexible adjustment based on specific usage environments and requirements. Rubber offers good elasticity and wear resistance, making it suitable for applications requiring frequent disassembly and installation; plastic offers lighter weight and good insulation properties, making it suitable for applications with weight and insulation requirements; and metal offers higher strength and corrosion resistance, making it suitable for applications with higher requirements for clamping force and durability. This flexibility in material selection allows the clamp to meet the needs and preferences of different users. Attached Figure Description

[0020] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0021] like Figures 1-2 As shown, this embodiment discloses a multi-layer copper busbar fixing fixture, including a clamping part and a docking part. The clamping part can fix a flat strip-shaped workpiece, and the docking part can fix the workpiece to the corresponding mounting surface.

[0022] In this embodiment, the workpiece is a flat strip, such as a copper busbar or ribbon cable, which needs to be fixed on the vehicle while also overcoming the bumps generated during vehicle operation. During vehicle operation, various vibrations and bumps occur, and these external forces can affect vehicle components, especially flat strips like copper busbars and ribbon cables. If not securely fixed, they can easily loosen, shift, or even be damaged, thus affecting the normal operation of the vehicle. The multi-layer copper busbar fixing clamp of this embodiment is designed to solve this problem. It can firmly fix these flat strips, and through reasonable structural design and material selection, it effectively absorbs and disperses the vibration energy generated during vehicle operation, reducing the impact on the workpiece and ensuring that the workpiece always remains in the correct position, thus guaranteeing the stability and reliability of the vehicle's electrical system.

[0023] The clamping part 10 has a U-shaped base plate 100 and side plates 200 connected to both sides of the base plate 100. The base plate 100 serves as the basic support structure of the clamping part 10, and its U-shaped design effectively provides a stable placement space for the workpiece 20. The side plates 200 are tightly connected to the base plate 100, together forming a complete clamping structure, ensuring that the workpiece 20 will not shift or fall off during clamping. The U-shaped design of the base plate 100 not only increases the stability of the clamping part 10 but also makes it easier to place and remove the workpiece 20. Simultaneously, the tight connection between the side plates 200 and the base plate 100 ensures the overall strength of the clamping structure, enabling it to withstand greater external forces, thereby ensuring the safety of the workpiece 20 during clamping.

[0024] Both side plates 200 have a first baffle 201 at a certain angle inclined towards the base plate 100 at their movable ends. The first baffle 201 applies pressure to the workpiece 20, improving its positioning in the thickness direction. As an important component of the clamping part 10, the inclined design of the first baffle 201 effectively applies pressure to the workpiece 20, ensuring accurate positioning in the thickness direction. This design not only improves clamping stability but also prevents the workpiece 20 from shifting under external forces. The first baffle 201 ensures sufficient pressure on the workpiece 20 without damaging it due to excessive angle. Furthermore, the connection between the first baffle 201 and the side plates 200 is optimized to ensure stability and durability during use. In addition, this design allows the workpiece 20 to automatically align during placement, improving production efficiency.

[0025] A support portion for supporting the workpiece 20 is provided on the end face of the base plate 100 facing the side plate 200. As another key part of the clamping part 10, the support portion mainly provides a stable support platform for the workpiece 20. Through the support portion, the workpiece 20 can remain stable during the clamping process and is not prone to shaking or tilting. The support portion ensures that it can fit tightly against the bottom of the workpiece 20 and provide uniform support force.

[0026] Two side plates 200 are provided with second baffles 202 inclined towards the base plate 100 on the side near the support. The highest point of the second baffles 202 is higher than the highest point of the support. This allows the second baffles 202 to compress the workpiece 20 when it is pressed into contact with the support, improving the stability of the workpiece 20 and ensuring its positioning in the width direction. The design of the second baffles 202 complements that of the first baffles 201, jointly ensuring the stability of the workpiece 20 during clamping. Through the compression action of the second baffles 202, the workpiece 20 can also be accurately positioned in the width direction, further improving the clamping accuracy.

[0027] The first baffle 201 is formed by bending the extension of the side plate 200. The bending angle α is 30°-60°. If the angle is too small, the coverage area in the thickness direction of the workpiece 20 will be small, which may easily cause the workpiece 20 to fall off. If the angle is too large, the force applied to the workpiece 20 will be too small. The bending forming process of the first baffle 201 not only simplifies the manufacturing process, but also improves the overall strength of the fixture. By reasonably controlling the bending angle α, it can be ensured that the first baffle 201 will not cause excessive damage to the workpiece 20 while applying pressure.

[0028] The angle β between the second baffle 202 and the side plate 200 must satisfy 120°≤β≤160°. If the angle is too small, it will be difficult to press the workpiece 20 down, causing it to remain suspended. However, if the angle is too large, the second baffle 202 may lose its squeezing effect. The angle β between the second baffle 202 and the side plate 200 is a key factor affecting its squeezing effect. By properly controlling the angle β, it can be ensured that the second baffle 202 can achieve the best effect when squeezing the workpiece 20.

[0029] A clearance groove 203 is provided on the side of the side plate 200 near the first baffle 201, and the depth of the clearance groove 203 is close to the thickness of the first baffle 201. Because the width of the workpiece 20 and the two side plates 200 adopt an interference fit, the workpiece 20 would not be able to enter without the clearance groove 203. The clearance groove 203 is designed to solve the interference problem that the workpiece 20 may encounter during placement. By setting the clearance groove 203, it can be ensured that the workpiece 20 can still smoothly enter the clamping part 10 even with an interference fit.

[0030] Two side plates 200 are provided with contact areas 204 between the clearance groove 203 and the second baffle 202, and the workpiece 20 is interference-fitted between the two contact areas 204. As the part of the side plate 200 that directly contacts the workpiece 20, the contact area 204 ensures that the workpiece 20 is stably clamped within the contact area 204 through the interference fit.

[0031] At least one side plate 200 has a thinned section 205 on its sidewall away from the contact area 204, which reduces the wall thickness of the side plate 200. This increases the flexibility of the side plate 200 and, consequently, improves the contact effect between the side plate 200 and the workpiece 20. The thinned section 205 is designed to increase the flexibility of the side plate 200, allowing it to better adapt to changes in the shape and size of the workpiece 20. By reducing the wall thickness of the side plate 200, its rigidity can be reduced, increasing its deformation capacity under external forces.

[0032] The support includes H-shaped horizontal ribs 102 and longitudinal ribs 101, which improve the support effect. The H-shaped horizontal ribs 102 and longitudinal ribs 101 together form a stable support structure, which can effectively distribute the weight of the workpiece 20 and the external forces it is subjected to, thereby improving the support effect.

[0033] The height difference L between the second baffle 202 and the support is such that L is not less than 1 / 5 of the height of the workpiece 20. This height difference L allows the second baffle 202 to better clamp the workpiece 20. The height difference L is designed to ensure that the second baffle 202 performs optimally when pressing the workpiece 20. By reasonably controlling the height difference L, the second baffle 202 can generate sufficient compressive force when pressing the workpiece 20 without causing excessive damage. When the height difference L is not less than 1 / 5 of the height of the workpiece 20, the second baffle 202 can provide sufficient compressive force to the workpiece 20 while ensuring that the workpiece 20 will not fall off or shift under external force. This design not only improves the stability of the workpiece 20 but also makes the fixture more versatile when clamping workpieces 20 of different heights. At the same time, the reasonable control of the height difference L also extends the service life of the second baffle 202 and reduces the risk of damage caused by excessive compression.

[0034] It also includes a docking part 30, which is connected to the end face of the base plate 100 away from the side plate 200, to facilitate fixing the clamping part 10 to other docking surfaces. The docking part 30 is designed to facilitate fixing the clamping part 10 to other equipment or structures, thereby improving its flexibility and versatility.

[0035] The docking part 30 and the clamping part 10 are integrally molded and made of rubber, plastic, or metal. This integral molding design ensures a strong connection and overall strength between the docking part 30 and the clamping part 10. Furthermore, the choice of rubber, plastic, or metal as the material allows for flexible adjustment based on specific usage environments and needs, meeting different clamping and fixing requirements. Rubber offers good elasticity and wear resistance, making it suitable for applications requiring frequent disassembly and installation; plastic offers lighter weight and good insulation properties, making it suitable for applications with weight and insulation requirements; and metal offers higher strength and corrosion resistance, making it suitable for applications with higher requirements for clamping force and durability. By selecting appropriate materials, the clamp can meet usage requirements while also possessing good economic efficiency and practicality.
