[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] Please see Figures 1 to 4 This application provides a hanger 1 for hanging a workpiece 2. The workpiece 2 may include a bottom wall and side walls surrounding the bottom wall, meaning the workpiece 2 is generally a frame-shaped structure. In other embodiments, the specific structure of the workpiece 2 may be modified.

[0026] The hanger 1 includes a hanger body 10, a first electrical connector assembly 100, and a second electrical connector 300. The hanger body 10 includes a first side 11 and a second side 12 opposite each other along a second direction, i.e., the X-axis, and a third side 13 and a fourth side 14 opposite each other along a first direction, i.e., the Y-axis. For example, the first side 11, the second side 12, the third side 13, and the fourth side 14 can be the front, back, left, and right spaces of the hanger body 10. The workpiece 2 is hung on the first side 11 and the second side 12 respectively. The first electrical connector assembly 100 is disposed on the third side 13 and the fourth side 14 and connected to the hanger body 10. The first electrical connector assembly 100 includes at least two first electrical connector assemblies 100, which elastically abut against and are electrically connected to the inner wall of the workpiece 2, providing elastic force to the workpiece 2 in the first direction, i.e., the Y-axis. The second electrical connector 300 extends from the hanger body 10 toward the first side 11 and the second side 12 respectively and passes through the workpiece 2, providing the workpiece 2 with a third-direction support force in the Z-axis direction. The second electrical connector 300 is electrically connected to the workpiece 2.

[0027] The hanger 1 provided in this application provides a fixing force in the Y-axis direction for the workpiece 2 by setting the first electrical connector group 100 to elastically abut and electrically connect with the inner wall of the workpiece 2, thereby preventing the workpiece 2 from swaying left and right, improving the flexibility of the hanger 1 application, solving the problem that the workpiece 2 is easily affected by the electroplating solution, resulting in unstable clamping and electroplating failure, ensuring the stability of the workpiece 2 and the uniform distribution of current during the electroplating process, thereby improving the quality and success rate of electroplating.

[0028] Please see Figure 1 and Figure 2In one embodiment of this application, the first electrical connector assembly 100 includes first connectors 101 respectively disposed on the third side 13 and the fourth side 14. Each first connector 101 includes an abutment end 1011 that abuts against and is electrically connected to the inner wall of the workpiece 2, a first fixed end 1012 disposed opposite to the abutment end 1011, and a first bent portion 1013 bent between the abutment end 1011 and the first fixed end 1012. The first fixed end 1012 is disposed on either the third side 13 or the fourth side 14, and the abutment end 1011 can extend obliquely toward either the first side 11 or the second side 12. The first bent portion 1013 can be compressed, thereby providing the abutment end 1011 with elastic force along a first direction, i.e., the Y-axis direction, so that the two first connectors 101 elastically abut against and are electrically connected to the inner wall of the workpiece 2. Therefore, a more stable fixation of the workpiece 2 and a reliable electrical connection are achieved. The two first connectors 101 are respectively disposed on the third side 13 and the fourth side 14 and are symmetrically distributed, enhancing the overall stability of the hanger 1. The first connector 101 provides elasticity through a bending structure, allowing the abutment end 1011 to elastically contact the inner wall of the workpiece 2, thereby ensuring a good electrical connection and fixing of the workpiece 2. The first connector 101 provides elasticity to the workpiece 2 along the Y-axis, effectively preventing displacement of the workpiece 2 due to liquid scouring during electroplating, further improving the fixing effect of the workpiece 2. This not only enhances the reliability of the electrical connection between the workpiece 2 and the hanger 1, but also ensures stability during the electroplating process and reduces the risk of electroplating failure.

[0029] Please see Figure 1 and Figure 2 In one embodiment of this application, among the plurality of first electrical connector groups 100, four first connectors 101 (i.e., the abutting end 1011 of the first connector 101 extends obliquely toward the first side 11) are provided. The four first connectors 101 are arranged in pairs opposite each other and respectively on the third side 13 and the fourth side 14. The four first connectors 101 are configured to fix the workpiece 2 located on the first side 11. The four first connectors 101 are symmetrically distributed on the third side 13 and the fourth side 14, generating uniform stress abutting against the workpiece 2. This can evenly distribute the weight of the workpiece 2 and the external force during the electroplating process, avoiding tilting or displacement problems caused by single-point fixing of the workpiece 2. All four first connectors 101 face the first side 11 and are used to fix the workpiece 2 on the first side 11, so that the hanger 1 can more accurately adapt to the shape and size characteristics of the workpiece 2, ensuring the stability of the workpiece 2 on the hanger 1. The arrangement of multiple connection points can effectively improve the uniformity of electroplating current distribution, reduce the risk of uneven electroplating, and thus improve the electroplating quality. Similarly, four first connectors 101 facing the second side 12 are also provided, located on the lower or upper side of the first connector 101 respectively, for fixing the workpiece 2 located on the second side 12.

[0030] Please see Figure 2 and Figure 3 In one embodiment of this application, two adjacent first connectors 101 located on the same side are spaced apart along the length of the workpiece 2. This spaced-apart arrangement of the first connectors 101 along the length of the workpiece 2 effectively avoids excessive local stress caused by stress concentration in the hanger 1, thereby extending the service life of the hanger 1. The spaced arrangement of the first connectors 101 allows for a more even distribution of the weight of the workpiece 2 and the external forces during the electroplating process, reducing deformation or loosening of the workpiece 2 due to localized load-bearing. The spaced arrangement also reduces vibration or displacement of the workpiece 2 caused by liquid scouring during electroplating, further improving the stability of the workpiece 2, effectively enhancing the stability and uniformity of the electroplating process, and thus improving product quality.

[0031] Please see Figure 3 In one embodiment of this application, a through hole 21 is provided on the workpiece 2, and a second electrical connector 300 is configured to pass through the through hole 21 so that the workpiece 2 is hung on the second electrical connector 300. The through hole 21 on the workpiece 2 provides positioning for the second electrical connector 300, avoiding the workpiece 2 from shifting or loosening due to inaccurate fixing position. The second electrical connector 300 passing through the through hole 21 enables a tighter contact between the workpiece 2 and the hanger 1, ensuring the stability of the workpiece 2 during the electroplating process, while providing a third-dimensional force, i.e., the Z-axis direction, to the workpiece 2. The through hole 21 effectively prevents the workpiece 2 from sliding or tilting due to the scouring of the electroplating solution, further improving the fixing effect of the workpiece 2.

[0032] Please see Figure 2 and Figure 3 In one embodiment of this application, the second electrical connector 300 is tilted relative to the hanger body 10. This prevents the workpiece 2 located on the first side 11 from moving in the X-axis direction, thereby improving the fixation stability of the workpiece 2.

[0033] Please see Figure 3 and Figure 4 In one embodiment of this application, the hanger 1 further includes a third electrical connector group 400. The third electrical connector group 400 includes a third connector 401 disposed on the first side 11 and the second side 12 and connected to the hanger body 10, and a fourth connector 402 disposed on the third connector 401 and connected to the workpiece 2. The fourth connector 402 can fix and electrically connect the workpiece 2, providing a tensile force in the second direction, i.e., the X-axis direction, to the workpiece 2. Therefore, the fourth connector 402 and the third connector 401 work together to ensure the stability of the workpiece 2 during the electroplating process. The arrangement of the third electrical connector group 400 can provide a more uniform current distribution, reducing the risk of uneven electroplating and thus improving the electroplating quality.

[0034] Please see Figure 2 In one embodiment of this application, the third connector 401 includes a second fixed end 4011 disposed on the hanger body 10, an extension end 4013 disposed opposite to the second fixed end 4011, and a second bent portion 4012 bent between the second fixed end 4011 and the extension end 4013, such that the third connector 401 is generally U-shaped. The third connector 401 passes through the space formed by the second fixed end 4011, the extension end 4013, and the second bent portion 4012. The extension end 4013 abuts against the fourth connector 402 and provides the fourth connector 402 with a tensile force along the second direction, i.e., the X-axis direction. At the same time, since the third connector 401 is fixed to the workpiece 2, the fourth connector 402 can fix the workpiece 2 to the hanger body 10 along the second direction, i.e., the X-axis direction, thereby ensuring the stability of the workpiece 2 and the good electrical connection. The design of the second bent portion 4012 can provide constant elasticity, avoiding the problem of loosening or deformation of the fourth connector 402 due to external factors. The tension design in the X-axis direction can effectively prevent the workpiece 2 from being displaced or tilted due to the scouring of the electroplating solution or other external forces, thereby further improving the fixing effect of the workpiece 2.

[0035] Please see Figure 3 and Figure 4 In one embodiment of this application, two sidewalls of the workpiece 2, arranged opposite each other along the Y-axis, are respectively provided with bayonets 20. The two ends of the fourth connector 402 pass through the bayonets 20 and are electrically connected to the workpiece 2. The middle portion of the fourth connector 402 is confined to the extension end 4013 and is electrically connected to the third connector 401. More specifically, the bayonets 20 form openings 22 at the edges of the sidewalls of the workpiece 2, and the edges of the sidewalls of the workpiece 2 extend towards the interior of the openings 22 to form abutment portions 23. The two ends of the fourth connector 402 abut against the abutment portions. By providing bayonets 20 on both sides of the workpiece 2 and coordinating the through-pass design of the fourth connector 402, the fixing stability of the workpiece 2 and the reliability of the electrical connection are further enhanced.

[0036] Please see Figure 1 and Figure 2In one embodiment of this application, the hanger body 10 further includes a hook portion 150 and a frame 151 connected to the hook portion 150. A first electrical connector group 100, a second electrical connector 300, and a third electrical connector group 400 are all disposed on the frame 151. The combined design of the hook portion 150 and the frame 151 provides stronger load-bearing capacity and higher impact resistance, thereby extending the service life of the hanger 1. The electrical connector groups, disposed on the frame 151, facilitate easier installation and adjustment, improving the ease of use of the hanger 1. The design of the frame 151 provides stronger support for the electrical connector groups, ensuring their stability and reliability during the electroplating process. The hook portion 150 also allows for convenient suspension of the hanger 1 in the electroplating tank, further improving the efficiency of the electroplating process.

[0037] This application also provides an electroplating apparatus, including the aforementioned hanger 1.
