Description

Technical Field

[0001] The present invention relates to the technical field of clamps, in particular to a multi-layer copper busbar fixing clamp. Background Art

[0002] In automotive manufacturing, electronic equipment installation, and various industrial scenarios, there is a growing demand for securing flat, strip-shaped workpieces such as multi-layer copper busbars and flat cables. These workpieces must withstand complex environments such as vibration and turbulence during vehicle operation or equipment operation, placing extremely high demands on the stability and reliability of their securing.

[0003] However, traditional workpiece fixing methods have many shortcomings. On the one hand, some fixing methods are cumbersome to operate during the installation process, which requires a lot of time and manpower and reduces production efficiency. For example, the use of bolt fastening not only requires pre-drilling holes at the installation location, which destroys the integrity of the installation surface, but also requires tightening the bolts one by one during the installation process, which is a complicated and inefficient process. On the other hand, the stability of traditional fixing methods is poor, and it is difficult to effectively cope with the vibration and bumps during vehicle operation or equipment operation. Simple clamp fixing methods, due to the lack of effective anti-loosening design, are prone to loosening due to vibration during long-term use, causing the workpiece to shift or even fall off, which in turn causes safety accidents or affects the normal operation of the equipment.

[0004] Furthermore, traditional fixing methods lack flexibility and are difficult to adapt to different installation orientations and workpiece layouts. In practical applications, the fixing method often needs to be flexibly adjusted based on the specific installation space and workpiece orientation. However, most existing fixing methods only support single-directional fixing and cannot meet the requirements of complex layouts such as cross-shaped fixing, limiting their application in certain specific scenarios.

[0005] To this end, we propose a multi-layer copper busbar fixing fixture. Summary of the Invention

[0006] Based on this, it is necessary to provide a multi-layer copper busbar fixing fixture to address the technical problems in the existing technology, such as the complex fixing method of the multi-layer copper busbar, poor fixing effect, and difficulty in adapting to different installation requirements, so as to make the fixing of the multi-layer copper busbar more stable and convenient, and meet the requirements of different installation directions.

[0007] The first aspect of the present invention provides a multi-layer copper busbar fixing fixture, comprising a first part, a second part, and a third part connected to each other. The first part comprises a first support plate with a U-shaped layout and first side walls on both sides of the first support plate, and the movable ends of the two first side walls are provided with a first baffle inclined at a certain angle toward the direction of the first support plate, for initially limiting the position of a workpiece such as a copper busbar; the second part is arranged on the other end face of the first support plate away from the first side wall, and comprises a connecting portion and an insert portion connected to both sides of the first support plate and arranged oppositely, and a pressure ring connected to the first support plate is further provided between the connecting portion and the insert portion, for further pressing and fixing the workpiece; the third part comprises a second support plate with a U-shaped layout and a second side wall and a bayonet portion connected on both sides of the second support plate, the second side wall is connected to the connecting portion, and the movable end of the bayonet portion is provided with a second baffle inclined at a certain angle toward the direction of the second support plate, for cooperating with the insert portion to achieve closed fixation of the fixture. The fixture makes the fixation of the multi-layer copper busbar more stable and convenient to operate through its unique structural design.

[0008] In other embodiments, the first part, the second part and the third part are integrally formed, which improves the overall strength and stability of the clamp, simplifies the manufacturing process and reduces production costs.

[0009] In other embodiments, the first baffle is formed by bending an extension of the first side wall, and the second baffle is formed by bending an extension of the bayonet portion, and the bending angle is 30°-60°. This design not only ensures the clamping effect of the baffle on the workpiece, but also avoids the problem of loose fixation or difficult clamping due to excessively large or small inclination angles.

[0010] In other embodiments, the connecting portion is located on the reverse extension line of the first side wall, or the connecting portion is arranged perpendicular to the reverse extension line of the first side wall. Such a design enables the clamp to adapt to the requirements of different installation directions, thereby improving the versatility of the clamp.

[0011] In other embodiments, the first support plate protrudes toward one side of the first side wall, and a baffle parallel to the first side wall is provided on the protruding surface. Such a design improves the contact effect between the first support plate and the workpiece, avoids the loosening of the workpiece, and at the same time, the setting of the baffle also prevents the workpiece from shaking on the plane of the first support plate.

[0012] In other embodiments, a avoidance groove is provided on the side of the first side wall close to the first baffle, and the depth of the avoidance groove on the horizontal plane is close to the thickness of the first baffle. Such a design avoids interference between the first baffle and the first side wall when clamping the workpiece, thereby ensuring smooth clamping.

[0013] In other embodiments, the plug-in portion includes a first plug-in and a second plug-in with the same structure but different sizes and distributed side by side, and the bayonet portion is provided with corresponding first bayonet and second bayonet. Such a design avoids the risk of the two plug-ins falling off at the same time, and further improves the clamping effect of the clamp.

[0014] In other embodiments, the pressure ring is O-shaped, and a pressure plate parallel to the first support plate is provided on the side of the pressure ring away from the first support plate. This design enables the pressure plate on the pressure ring to fully contact the surface of the workpiece, and cooperates with the second baffle to improve the clamping effect of the workpiece.

[0015] In other embodiments, the connecting portion includes a weakened portion with a reduced wall thickness, and the weakened portion is provided to facilitate the flipping of the second portion to the third portion. This design makes the clamp more convenient when the fixing direction needs to be adjusted or disassembled.

[0016] In other embodiments, a fourth part is also included, which is a docking joint, which is connected to the end face of the second support plate in the third part away from the second baffle. This design enables the clamp to be easily docked and fixed with other structures, thereby improving the installation convenience of the clamp. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0026] like Figure 1-Figure 2As shown, this embodiment discloses a multi-layer copper busbar fixing fixture, including a first part 100, a second part 200, a third part 300 and a fourth part 400 connected to each other, which can fix at least two layers of workpieces and fix the workpieces to the corresponding mounting surface.

[0027] The workpieces in this embodiment are flat, strip-shaped objects, such as copper busbars and cable trays, that need to be fixed to the vehicle and withstand the jolting motions generated by the vehicle during operation. During vehicle operation, various vibrations and jolting occur, and these external forces can impact the vehicle's components. Flat, strip-shaped objects like copper busbars and cable trays, in particular, can easily become loose, shift, or even damaged if not securely fixed, thus affecting the vehicle's normal operation. The multi-layer copper busbar fixing fixture of this embodiment is designed to address this problem. It securely secures these flat, strip-shaped objects. Through rational structural design and material selection, it effectively absorbs and disperses the vibration energy generated by the vehicle during operation, reducing impact on the workpiece and ensuring that the workpiece remains in the correct position, thereby ensuring the stability and reliability of the vehicle's electrical system. For example, in new energy vehicles, copper busbars serve as important conductive elements connecting key components such as battery packs and motors. The stability of their fixation is directly related to the vehicle's performance and safety. This fixing fixture can provide reliable fixation for the copper busbars, avoiding problems such as poor contact and short circuits caused by vibration, thereby improving the safety and reliability of new energy vehicles.

[0028] Specifically, the first portion 100 in this embodiment comprises a first support plate 101 in a U-shaped arrangement and first side walls 102 on both sides of the first support plate 101. A first accommodating cavity for accommodating a workpiece is provided between the two first side walls 102. The movable ends of the two first side walls 102 are each provided with a first blocking piece 103 inclined at a certain angle toward the first support plate 101.

[0029] The first part 100 is the key part of the entire fixing fixture that directly contacts the workpiece and plays a role in preliminary fixing. The first support plate 101 is arranged in a U-shaped layout. This design not only provides a stable support base, but also its U-shaped structure can better fit the shape of the workpiece, increase the contact area, and thus improve the stability of the fixation. The first side walls 102 are arranged on both sides of the first support plate 101. Together with the first support plate 101, they form a first accommodating cavity. The size of this accommodating cavity is carefully designed according to the size of the workpiece to ensure that the workpiece can be just placed therein, and it will not be too loose to cause shaking, nor too tight to be difficult to install. The first baffle 103 is tilted at a certain angle toward the direction of the first support plate 101. The design of this angle is very clever. It can prevent the workpiece from sliding out of the first accommodating cavity without causing too much obstruction to the installation of the workpiece. In practice, when a workpiece is placed in the first receiving chamber, the first baffle 103 utilizes its elastic deformation capability to slightly bend outward under the pressure of the workpiece. Once the workpiece is fully inserted, the first baffle 103 returns to its original shape, firmly pressing against the workpiece to prevent it from falling out. This design not only improves the reliability of the fixation but also makes the installation and removal of the workpiece more convenient and quick. Furthermore, the tilt angle of the first baffle 103 can be adjusted according to actual needs to accommodate workpieces of different sizes and shapes, further enhancing the versatility and flexibility of the fixing fixture.

[0030] The second part 200 in this embodiment is arranged on the other end face of the first support plate 101 away from the first side wall 102. The second part 200 includes a connecting portion 201 and an insert portion 202 connected to both sides of the first support plate 101 and arranged relative to each other. The relative arrangement in this embodiment refers to the face-to-face arrangement of a connecting portion 201 and an insert portion 202. In this embodiment, the connecting portion 201 and the insert portion 202 are located at the reverse extension of the first side wall 102. At this time, the workpiece accommodated by the first part 100 and the workpiece accommodated by the third part 300 have the same orientation. However, in another embodiment, the connecting portion 201 and the insert portion 202 are arranged relative to each other on the first support plate 101. At this time, the orientation of the connecting portion 201 and the insert portion 202 is perpendicular to the reverse extension direction of the first side wall 102. At this time, the workpiece accommodated by the first part 100 and the workpiece accommodated by the third part 300 are perpendicular to each other, which can realize cross-fixation of workpieces in two directions, and a pressure ring 203 connected to the first support plate 101 is further provided between the connecting portion 201 and the insert portion 202 to further cooperate with the second baffle 305 to fix the workpiece.

[0031] The second part 200 plays a dual role of connection and fixation in the entire fixing fixture. The relative arrangement of the connecting part 201 and the plug-in part 202 is very flexible and can be adjusted according to actual needs. When they are located at the reverse extension of the first side wall 102, the workpieces accommodated by the first part 100 and the third part 300 are oriented in the same direction. This arrangement is suitable for some situations where the workpieces need to be fixed in the same direction. For example, in the vehicle electrical system, certain lines need to be arranged in a specific direction to ensure the normal transmission of current and the stable transmission of signals. In another embodiment, when the orientation of the connecting part 201 and the plug-in part 202 is perpendicular to the reverse extension direction of the first side wall 102, the workpieces accommodated by the first part 100 and the third part 300 are oriented perpendicularly, which can achieve cross-fixation of workpieces in two directions. This design greatly increases the versatility of the fixing fixture and can meet the needs of the workpiece fixing direction in different scenarios. The setting of the pressure ring 203 further enhances the fixing effect of the workpiece. It is connected to the first support plate 101, located between the connecting portion 201 and the insert portion 202. When the workpiece is secured in the fixture, the pressure ring 203 maintains close contact with the workpiece surface and, in conjunction with the second stopper 305, applies pressure to the workpiece, preventing it from moving within the fixture. The pressure ring 203 is typically made of elastic rubber or plastic to ensure moderate pressure on the workpiece without damaging it.

[0032] The third part 300 in this embodiment has a U-shaped second support plate 301 and a second side wall 302 and a bayonet portion 303 connected on both sides of the second support plate 301. The second side wall 302 is connected to the connecting portion 201, and a second blocking piece 305 is provided on the movable end of the bayonet portion 303, which is inclined at a certain angle toward the second support plate 301.

[0033] The third part 300 is similar to the first part 100 and is also an important part for accommodating and fixing the workpiece. The second support plate 301 is U-shaped, providing stable support for the workpiece. The second side wall 302 is connected to the connecting part 201, making the structure of the entire fixing fixture more compact and firm. The second baffle 305 provided on the movable end of the bayonet portion 303 is similar to the first baffle 103 in the first part 100. Both are inclined at a certain angle toward the support plate to prevent the workpiece from sliding out. The design of the second baffle 305 also takes into account the convenience of installation and disassembly of the workpiece. Its inclination angle can ensure that it will not cause excessive resistance when the workpiece is installed, and can effectively prevent the workpiece from falling off after being fixed. In addition, the structural design of the bayonet portion 303 also has a certain degree of elasticity. When the plug-in portion 202 is inserted, the bayonet portion 303 will open slightly. After the plug-in portion 202 is fully inserted, the bayonet portion 303 will return to its original shape and tightly clamp the plug-in portion 202, thereby achieving a firm connection between the first part 100 and the third part 300, further improving the stability of the entire fixing clamp.

[0034] Among them, the plug-in part 202 is plugged into the bayonet part 303, and a plug-in slot 304 for accommodating the plug-in part 202 is also provided in the bayonet part 303. The plug-in part 202 and the bayonet part 303 are plugged into each other and are the key design of the fixing fixture for achieving rapid installation and disassembly. The provision of the plug-in slot 304 enables the plug-in part 202 to be accurately inserted into the bayonet part 303, and ensures stability and firmness after insertion. The size and shape of the plug-in slot 304 match the plug-in part 202, and can tightly wrap the plug-in part 202 to prevent it from loosening. In actual application, when it is necessary to fix the workpiece in the fixture, it is only necessary to align the plug-in part 202 with the plug-in slot 304 of the bayonet part 303, and then gently insert it. The whole process is simple and fast, which greatly improves work efficiency. Moreover, this plug-in method is also convenient for maintenance and replacement of the clamp. When the clamp is damaged or needs to be replaced with a clamp of different specifications, the plug-in part 202 only needs to be pulled out from the bayonet part 303 to easily complete the disassembly and replacement operations.

[0035] In this embodiment, the first part 100, the second part 200, and the third part 300 are integrally molded. Furthermore, in this embodiment, the first part 100, the second part 200, the third part 300, and the fourth part 400 are integrally injection molded from rubber or plastic. This integral molding design makes the entire fixture structure more compact and robust, reduces gaps between components, and improves the overall strength and stability of the fixture. The rubber or plastic integral injection molding process offers advantages such as high production efficiency, low cost, and high product precision. Through injection molding, the size and shape of the fixture can be precisely controlled, ensuring consistent quality and performance for each fixture. Furthermore, rubber or plastic materials have excellent elasticity and corrosion resistance, making them suitable for various harsh environments encountered during vehicle operation, such as high temperature, humidity, and vibration. Furthermore, these materials possess certain insulating properties, effectively preventing current leakage and enhancing the safety of the vehicle's electrical system. In actual production, the use of an integral injection molding process can significantly improve production efficiency and reduce production costs while ensuring product quality and performance, making this multi-layer copper busbar fixing fixture highly competitive in the market.

[0036] In this embodiment, the first baffle 103 is formed by bending an extension of the first sidewall 102, and the second baffle 305 is formed by bending an extension of the bayonet portion 303. The bending angle α is between 30° and 60°. When α is less than 30°, the engagement is easy, that is, the workpiece can easily pass through the first baffle 103 and the second baffle 305. However, the first baffle 103 and the second baffle 305 cover a smaller area on the workpiece, making them more likely to fall off. When α is greater than 60°, although the baffle covers a larger area on the workpiece, the excessively large inclination angle reduces the pressing force of the baffle on the workpiece, which also poses a risk of falling off. Designing the first baffle 103 and the second baffle 305 as bent extensions not only simplifies the production process and reduces production costs, but also provides a more secure connection between the baffles, the support plate, and the sidewall. The selection of the bending angle α has been carefully considered. When the α value is less than 30°, although the workpiece can easily pass through the baffle, the baffle covers a small area on the workpiece and cannot provide sufficient blocking force, which can easily cause the workpiece to fall off. When the α value is greater than 60°, although the area covered by the baffle on the workpiece increases, the pressing force of the baffle on the workpiece will be reduced due to the excessive inclination angle, and there is also a risk of falling off. Therefore, controlling the bending angle α between 30°-60° can not only ensure the smooth installation of the workpiece, but also provide sufficient blocking force and pressing force to ensure that the workpiece is firmly fixed in the fixture. In actual application, the bending angle α can be further optimized according to the specific size and weight of the workpiece to achieve the best fixing effect.

[0037] In this embodiment, the connecting portion 201 is located on the reverse extension line of the first side wall 102, or the connecting portion 201 is arranged perpendicular to the reverse extension line of the first side wall 102. These two settings of the connecting portion 201 each have its own advantages. When the connecting portion 201 is located on the reverse extension line of the first side wall 102, the structure of the entire fixing fixture is more symmetrical, which is convenient for installation and layout. This setting is suitable for some scenarios with high space requirements and the need for workpieces to be fixed in the same direction. When the connecting portion 201 is arranged perpendicular to the reverse extension line of the first side wall 102, cross-fixation of workpieces in two directions can be achieved, which greatly increases the versatility and flexibility of the fixing fixture. In actual applications, the appropriate setting method of the connecting portion 201 can be selected according to the specific installation requirements and the fixing direction of the workpiece to meet different usage scenarios.

[0038] In this embodiment, Figure 2 As shown, the first support plate 101 protrudes toward one side of the first side wall 102, and a baffle 1011 parallel to the first side wall 102 is provided on the protruding surface. The protruding design on the first support plate 101 increases the contact area with the workpiece, improves the contact effect, and prevents the workpiece from loosening. The provision of the baffle 1011 further prevents the workpiece from shaking on the plane of the first support plate 101. When the width of the workpiece is less than the distance between the two first side walls 102, the baffle 1011 can play a blocking role, preventing the workpiece from moving left and right in the first accommodating cavity, ensuring that the workpiece always remains in the correct position. In addition, the baffle 1011 can also be customized according to the shape and size of the workpiece to better adapt to different workpiece requirements. In practical applications, this design can effectively improve the stability and reliability of workpiece fixation and reduce failures and damage caused by workpiece shaking.

[0039] Therefore, the protrusions and the baffles 1011 on the first support plate 101 improve the contact effect with the workpiece and prevent the workpiece from loosening. In addition, by setting the baffles 1011, the width of the workpiece is prevented from being less than the distance between the two first side walls 102, and the workpiece is prevented from shaking on the plane of the first support plate 101. In actual applications, various vibrations and bumps will be generated during the operation of the vehicle. If the workpiece is loose or shakes in the fixing fixture, it will not only affect the normal operation of the vehicle's electrical system, but may also cause the workpiece to collide with other components and cause damage. The design of the protrusions and the baffles 1011 on the first support plate 101 effectively solves this problem. The protrusions increase the contact area with the workpiece, allowing the workpiece to fit more closely on the first support plate 101, reducing the possibility of shaking. The baffles 1011 further limit the range of motion of the workpiece, ensuring that the workpiece always remains in the correct position. This design not only improves the stability of the workpiece fixation, but also extends the service life of the workpiece and the fixing fixture, and reduces maintenance costs.

[0040] In this embodiment, a relief groove 1021 is provided on the side of the first side wall 102 close to the first baffle 103, and the depth of the relief groove 1021 in the horizontal plane is close to the thickness of the first baffle 103. The relief groove 1021 is provided to prevent the first baffle 103 from interfering with the first side wall 102 during the bending process. When the first baffle 103 is bent, if there is no relief groove 1021, the first baffle 103 may be squeezed against the first side wall 102, resulting in the first baffle 103 being unable to bend normally, or being deformed or damaged after bending. The presence of the relief groove 1021 provides the first baffle 103 with sufficient bending space, allowing the first baffle 103 to be smoothly bent to the predetermined angle and ensuring that the shape and size after bending meet the design requirements. In addition, the depth of the avoidance groove 1021 in the horizontal plane is close to the thickness of the first baffle 103 , which can ensure that the first baffle 103 has sufficient bending space while not affecting the strength and stability of the first side wall 102 due to the avoidance groove 1021 being too deep.

[0041] The width of the workpiece is the same as the spacing between the first side walls 102, and the connection is made by interference. The use of an interference connection method can ensure a close fit between the workpiece and the fixing fixture, thereby improving the reliability of the fixation. When the width of the workpiece is the same as the spacing between the first side walls 102, the workpiece will be tightly clamped between the two first side walls 102 through the interference connection, and will not be loose or shaking. During the actual installation process, a certain amount of pressure needs to be applied to press the workpiece into the first accommodating cavity. Although the installation may be a little more laborious, once the installation is completed, the workpiece will be firmly fixed in the fixture and can withstand various vibrations and impacts during the operation of the vehicle. This interference connection method is suitable for scenarios with high requirements for fixing stability, such as fixing key components in the vehicle electrical system.

[0042] The workpiece is difficult to fit in. Although the interference fit connection can improve the reliability of the fixation of the workpiece, it may also cause certain difficulties in the installation of the workpiece. In order to solve this problem, in actual operation, some auxiliary tools can be used, such as special installation fixtures or lubricants. The special installation fixture can provide uniform pressure to help press the workpiece smoothly into the first accommodating cavity, reducing the resistance and difficulty during the installation process. The lubricant can reduce the friction between the workpiece and the first side wall 102, making it easier for the workpiece to slide into the first accommodating cavity. In addition, when designing the fixing fixture, the inner surface of the first side wall 102 can also be smoothed to further reduce friction and improve the convenience of installation.

[0043] In this embodiment, the plug-in portion 202 includes a first plug-in portion 2021 and a second plug-in portion 2022, which are identical in structure but different in size and arranged side by side. The bayonet portion 303 is also provided with corresponding first bayonet openings 3031 and second bayonet openings 3032. Designing the plug-in portion 202 as having the first plug-in portion 2021 and second plug-in portion 2022, which are identical in structure but different in size and arranged side by side, and providing the bayonet portion 3033 with corresponding first bayonet openings 3031 and second bayonet openings 3032 further enhances the clamping effect and prevents the two plugs from falling out simultaneously. In practice, when the plug-in portion 202 is inserted into the bayonet portion 303, the first plug-in portion 2021 and the second plug-in portion 2022 will respectively insert into the corresponding first bayonet openings 3031 and second bayonet openings 3032. Due to the different sizes of the two plugs, their degree of fit with the bayonet openings will also vary. Thus, even if one plug-in portion shows signs of loosening due to external force, the other plug-in portion will remain securely engaged in the bayonet opening, ensuring the stability of the entire fixture. In addition, this design can also be adjusted according to actual needs, such as increasing or decreasing the number of plug-ins, changing the size and distribution of plug-ins, etc., to adapt to the fixation of workpieces with different specifications and requirements.

[0044] Prevent two plug-ins from falling off at the same time, and further improve the clamping effect. In actual applications, various complex vibrations and impact forces will be generated during the operation of the vehicle. If the clamping effect of the fixing fixture is not good, it is easy to cause the plug-in to fall off, thereby affecting the fixing stability of the workpiece. By setting a first plug-in 2021 and a second plug-in 2022 with the same structure but different sizes and distributed side by side, as well as the corresponding first bayonet 3031 and second bayonet 3032, the situation where the two plug-ins fall off at the same time is effectively avoided. Even if one of the plug-ins is subjected to a large external force, due to the different size and degree of fit of the other plug-in, it can still provide sufficient clamping force to ensure the stability of the entire fixing fixture. This design greatly improves the reliability and safety of the fixing fixture, and reduces the occurrence of failures and accidents caused by the falling off of the plug-in.

[0045] According to the multi-layer copper busbar fixing fixture of the present embodiment of claim 1, the pressure ring 203 is O-shaped, and a pressure plate parallel to the first support plate 101 is provided on the side of the pressure ring 203 away from the first support plate 101. The pressure ring 203 is designed in an O-shape, which can evenly apply pressure to the workpiece and improve the clamping effect. A pressure plate parallel to the first support plate 101 is provided on the side of the pressure ring 203 away from the first support plate 101, which further increases the contact area with the workpiece, so that the pressure plate on the pressure ring 203 can better contact the surface of the workpiece, and cooperates with the second baffle 305 to improve the clamping effect on the workpiece. In actual application, when the workpiece is fixed in the fixture, the pressure plate will be tightly pressed on the surface of the workpiece to prevent the workpiece from shaking in the fixture. Moreover, the design of the pressure plate can also be customized according to the shape and size of the workpiece to better adapt to different workpiece requirements. This design can effectively improve the stability and reliability of workpiece fixation and ensure the normal operation of the vehicle electrical system.

[0046] At this time, the pressure plate on the pressure ring 203 can come into contact with the surface of the workpiece, and cooperate with the second baffle 305 to improve the clamping effect of the workpiece. In actual applications, various vibrations and impact forces will be generated during the operation of the vehicle. If the workpiece is loose or shakes in the fixing fixture, it will affect the normal operation of the vehicle's electrical system. The use of the pressure plate on the pressure ring 203 and the second baffle 305 can effectively improve the clamping effect of the workpiece. The pressure plate applies pressure to the workpiece from above, and the second baffle 305 blocks the workpiece from sliding out from the side. The two work together to firmly fix the workpiece in the fixture. Moreover, the material of the pressure plate and the second baffle 305 is usually selected from rubber or plastic with a certain elasticity, which can ensure that the pressure on the workpiece is moderate without causing damage to the workpiece. This design can effectively improve the stability and reliability of the workpiece fixation and reduce failures and damage caused by the shaking of the workpiece.

[0047] In this embodiment, the connecting portion 201 includes a weakened portion with reduced wall thickness. While the original text does not provide a corresponding number for the weakened portion, it can be supplemented by describing the weakened portion as a specific area on the connecting portion 201, which is not currently numbered or can be supplemented with a number such as 2011. The weakened portion is provided to facilitate the flipping of the second portion 200 toward the third portion 300. The weakened portion is provided to facilitate the flipping of the second portion 200 toward the third portion 300, thereby facilitating the installation and removal of the workpiece. In practical applications, when a workpiece needs to be secured in the fixture, the second portion 200 can be flipped to make it easier for the insert portion 202 to be inserted into the bayonet portion 303. The design of the weakened portion results in a relatively low strength of the connecting portion 201 in this area, making it easier to bend and deform when subjected to certain external forces, thereby enabling the flipping operation. Furthermore, the provision of the weakened portion does not affect the structural strength and stability of the entire fixture. Under normal use, the fixture can securely secure the workpiece. When the workpiece needs to be removed, the second portion 200 can be flipped over to remove the insert portion 202 from the bayonet portion 303, completing the removal operation. This design greatly improves the convenience of installing and disassembling workpieces and improves work efficiency.

[0048] This embodiment also includes a fourth portion 400, which is a docking joint 401. This joint connects to the end face of the second support plate 301 of the third portion 300, facing away from the second baffle 305. In this embodiment, the docking joint 401 is a fir-tree head. The docking joint 401 of the fourth portion 400 is a key component for connecting the entire fixture to other structures. In this embodiment, the docking joint 401 is a fir-tree head. Its unique shape and structure enable tight docking with other structures, ensuring a secure and reliable connection. In practical applications, by docking the docking joint 401 with other structures, the entire fixture can be fixed to a designated location on the vehicle, thereby securing the workpiece. The docking joint 401 can also be designed as a bolt, screw, or staple, depending on the installation requirements and connection method. This design makes the fixture highly versatile and adaptable, meeting the installation requirements of various scenarios. Furthermore, the design of the docking joint 401 can be customized according to actual needs, such as by changing its size, shape, and material to better accommodate docking with other structures.

[0049] The specific working principle is as follows:

[0050] Two workpieces (the two workpieces can be the same or different, such as two copper busbars, or a copper busbar and a busbar) are clamped between the two first side walls 102 and between the bayonet portion 303 and the second side wall 302. Then, by rotating the connecting portion 201, the plug-in portion 202 on the second part 200 is inserted into the bayonet portion 303 in the third part 300, thereby fixing the two workpieces. Then, the docking joint 401 in the fourth part 400 is fixed to the corresponding position, thereby achieving docking of the workpieces. In actual operation, the two workpieces are first placed in the first accommodating cavity of the first part 100 and the space enclosed by the bayonet portion 303 and the second side wall 302 of the third part 300. Since the width of the workpiece is the same as the spacing between the first side walls 102 and the connection is made by interference fit, the workpiece will be tightly clamped in the fixture. Then, by rotating the connecting portion 201, the plug-in portion 202 on the second part 200 is aligned with the bayonet portion 303 in the third part 300, and the plug-in portion 202 is inserted into the bayonet portion 303. During the insertion process, the bayonet portion 303 will open slightly. After the plug-in portion 202 is fully inserted, the bayonet portion 303 will return to its original state and tightly clamp the plug-in portion 202, thereby achieving a firm connection between the first part 100 and the third part 300, further fixing the two workpieces. Finally, through the docking joint 401 in the fourth part 400, the entire fixing fixture is fixed to the designated position on the vehicle, completing the docking and fixing of the workpieces. The entire operation process is simple and fast, can effectively improve work efficiency, and ensure the stability and reliability of the workpiece fixation.
