Abstract
Description
Technical Field
[0001] This utility model relates to the field of electroplating technology, specifically to an electroplating conductive fixture. Background Technology
[0002] Electroplating is a process that uses electrolysis to deposit a thin layer of another metal or alloy onto a metal surface. It is an essential step in wafer fabrication and PCB manufacturing. The fixtures used in electroplating need to have both clamping and conductive functions. Existing electroplating fixtures use a metal frame structure to achieve conductivity, and employ screws to fix springs to the metal frame structure, with silicone coating on the springs to achieve clamping. However, because the main metal structure needs to be immersed in the electroplating solution for a long time, it will be corroded by the solution, resulting in a short lifespan. Furthermore, the silicone-coated springs are consumable parts (and their manufacturing cost is high), all of which contribute to the high cost of existing electroplating fixtures. Utility Model Content
[0003] Therefore, in order to overcome the above problems, this utility model provides an electroplated conductive fixture with a long service life and low cost, which uses a conductive core encased in an insulating main frame to achieve the conductive function and an insulating clamping member set with the insulating main frame and the corresponding edge of the insulating main frame to achieve the clamping function.
[0004] Therefore, this utility model provides an electroplating conductive fixture, comprising:
[0005] An insulating main frame, the four sides of which enclose a space for the object to be electroplated; the four sides of the insulating main frame include at least two conductive sides, and a conductive core is enclosed within the conductive sides; the conductive core includes a conductive arm and several electrical terminals disposed on the conductive arm, one end of the conductive arm protruding outside the insulating main frame to form an electrical contact piece, and the electrical terminals protruding outside the insulating main frame at the periphery of the space.
[0006] At least two insulating clamps are provided corresponding to each conductive frame, and the insulating clamps have a number of insulating clamp heads corresponding to the electrical terminals; when one side of the object to be electroplated is in contact with the electrical terminal, the corresponding insulating clamp head presses against the other side of the object to be electroplated to clamp the object to be electroplated in the accommodating space.
[0007] Optionally, the conductive core includes several self-conducting arms extending outward toward the periphery of the accommodating space to form electrical contact arms, the ends of the electrical contact arms being provided with electrical contact holes, and the electrical contact ends being disposed within the electrical contact holes.
[0008] Optionally, there are two conductive borders, which are set opposite to each other.
[0009] Optionally, the insulating clamp is provided with a rotating shaft, and the insulating main frame is provided with a corresponding shaft connection assembly. The insulating clamp can rotate relative to the insulating main frame through the rotating shaft and the shaft connection assembly, so that there is an opening between the insulating clamp head and the corresponding electrical terminal. An elastic element is also provided between the insulating clamp and the insulating main frame, and the elastic element drives the insulating clamp head of the insulating clamp to press against the object to be electroplated.
[0010] Optionally, the shaft connection assembly includes a first shaft connection block and a second shaft connection block. The first shaft connection block and the second shaft connection block are respectively disposed on both sides of the rotating shaft in the circumferential direction and are offset in the axial direction of the rotating shaft. The first shaft connection block and the second shaft connection block are respectively provided with a first arc groove and a second arc groove, and the rotating shaft is inserted between the first arc groove and the second arc groove.
[0011] Optionally, the insulating main frame is also provided with a limiting component, which includes at least one first limiting block and at least one second limiting block, with the first limiting block and the second limiting block respectively disposed on both sides of the circumferential direction of the rotating shaft.
[0012] Optionally, the rotating shaft is located on the side of the insulating clamp away from the accommodating space, and the elastic element is located on the side of the insulating clamp close to the accommodating space; a first hook rod and a second hook rod are respectively provided on the insulating clamp and the insulating main frame, and the elastic element is a tension spring with its two ends hooked on the first hook rod and the second hook rod respectively.
[0013] Optionally, the insulating clamping member includes a frame-shaped body and a plurality of insulating clamping arms extending outward from the frame-shaped body toward the periphery of the accommodating space. The ends of the insulating clamping arms are provided with crimping holes, and the insulating clamping heads are disposed in the crimping holes.
[0014] Optionally, the insulating clamping head is a rubber end, which includes a first section, a second section, a third section, and a fourth section arranged sequentially from its first end to its second end. The diameters of the first and third sections correspond to the diameters of the crimping hole. The diameter of the second section is larger than the diameter of the crimping hole, and the diameter of the second section gradually increases as it approaches the third section. The diameter of the fourth section is larger than the diameter of the crimping hole. When the rubber end is pressed into the crimping hole from the first end, the third section is located inside the crimping hole, and the second and fourth sections abut against the two end faces of the crimping hole, respectively.
[0015] The technical solution of this utility model has the following advantages:
[0016] 1. The electroplating conductive fixture provided by this utility model achieves conductivity by encasing the conductive core within the conductive frame of the insulating main frame, and by using the ends of the conductive arms and electrical terminals of the conductive core exposed outside the insulating main frame. This prevents the conductive core from being corroded by conductive liquid, thus allowing the electroplating conductive fixture to have a long service life as long as the insulating main frame is made of corrosion-resistant material. At the same time, by setting an insulating clamping component corresponding to the conductive frame to achieve the clamping function in conjunction with the insulating main frame, the insulating clamping component is easy to manufacture as an integral insulating component and is no longer a vulnerable part, thus reducing its manufacturing and usage costs. Therefore, the electroplating conductive fixture has a low usage cost.
[0017] 2. The electroplating conductive fixture provided by this utility model achieves the opening function between the insulating clamp and the insulating main frame by setting a rotating shaft and a shaft connection assembly on the insulating clamp and the insulating main frame respectively, and achieves the clamping function between the insulating clamp and the insulating main frame by setting an elastic element between the insulating clamp and the insulating main frame. This makes the vulnerable parts (easily corroded and requiring frequent replacement) between the insulating clamp and the insulating main frame only easy-to-replace and low-cost metal elastic elements, which can further reduce the use cost of the electroplating conductive fixture.

[0048] Please refer to Figures 1-6 This is a schematic diagram of the structure of an electroplating conductive fixture provided in an embodiment of the present utility model. The electroplating conductive fixture includes an insulating main frame 100, a conductive core 200, and an insulating clamping member 300.
[0049] Please refer to Figure 1 The insulating main frame 100 is surrounded by four borders to form an accommodating space for the object to be electroplated 400. The four borders of the insulating main frame 100 include at least two conductive borders, and the conductive core 200 is enclosed within the conductive borders.
[0050] In this embodiment, in order to ensure the corrosion resistance of the insulating main frame 100, its material can be set to high-performance plastic; specifically, the material of the insulating main frame 100 can be set to polyvinylidene fluoride (PVDF).
[0051] In this embodiment, the insulating main frame 100 can be injection molded as a single piece.
[0052] In this embodiment, there can be two conductive borders, which are arranged opposite to each other. In this embodiment, there can also be three conductive borders.
[0053] Please refer to Figure 1 , Figure 2 and Figure 5 The conductive core 200 includes a conductive arm 210 and a plurality of electrical terminals 220 disposed on the conductive arm 210. One end of the conductive arm 210 protrudes outside the insulating main frame 100 to form an electrical contact piece 230, and the electrical terminals 220 protrude outside the insulating main frame 100 at the periphery of the accommodating space.
[0054] In this embodiment, when there are two conductive cores 200, one end of their conductive arm 210 can be set to protrude outside the insulating main body frame 100 at the same edge of the insulating main body frame 100 to facilitate electrical connection.
[0055] In this embodiment, the conductive core 200 may include a plurality of self-conducting arms 210 extending outward toward the periphery of the accommodating space to form electrical contact arms 240, the ends of the electrical contact arms 240 being provided with electrical contact holes 241, and electrical contact ends 220 being disposed within the electrical contact holes 241.
[0056] Specifically, the electrical connector 220 can be set as a rivet, and the rivet is pressed into the electrical connector hole 241 to realize the connection between it and the electrical connector arm 240.
[0057] Please refer to Figure 1 and Figure 3 The insulating clamp 300 is configured with at least two corresponding to the conductive frame, and the insulating clamp 300 has a plurality of insulating clamp heads 310 corresponding to the electrical terminal 220.
[0058] In this embodiment, in order to ensure the corrosion resistance of the insulating clamp 300, its material can be set to high-performance plastic; specifically, the material of the insulating clamp 300 can be set to polyvinylidene fluoride (PVDF).
[0059] In this embodiment of the electroplating conductive fixture, when one side of the object to be electroplated 400 is in contact with the electrical terminal 220, the corresponding insulating clamping head 310 presses against the other side of the object to be electroplated 400 to clamp the object to be electroplated 400 in the accommodating space.
[0060] In this embodiment, the electroplating conductive fixture achieves conductivity by enclosing the conductive core 200 within the conductive frame of the insulating main body frame 100, and by using the conductive arm of the conductive core 200 exposed outside the insulating main body frame 100 and the electrical terminal 220. This allows the electroplating conductive fixture to have a long service life as long as the insulating main body frame 100 is made of a corrosion-resistant material. Simultaneously, an insulating clamping member 300, corresponding to the conductive frame, is provided to cooperate with the insulating main body frame 100 in clamping. This insulating clamping member 300, being an integral insulating component, is easy to manufacture and is not a vulnerable part, resulting in lower manufacturing and usage costs. Therefore, the electroplating conductive fixture has a low operating cost.
[0061] In one optional embodiment of this example, in order to further reduce the manufacturing cost of the electroplating conductive fixture in this example, such as Figure 3 and Figure 4 As shown, a rotating shaft 320 can be provided on the insulating clamp 300, and a corresponding shaft connection assembly 110 can be provided on the insulating main frame 100, so that the insulating clamp 300 can rotate relative to the insulating main frame 100 through the rotating shaft 320 and the shaft connection assembly 110, and there is an opening between the insulating clamp head 310 and the corresponding electrical terminal 220; an elastic element 500 is provided between the insulating clamp 300 and the insulating main frame 100, and the elastic element 500 drives the insulating clamp head 310 of the insulating clamp 300 to press against the object to be electroplated 400. At this time, the only vulnerable part (easily corroded and requiring frequent replacement) between the insulating clamp 300 and the insulating main frame 100 is the metal elastic element 500, which is easy to replace and has a low cost, which can further reduce the use cost of this electroplating conductive fixture.
[0062] In this embodiment, the shaft connection component 110 can be a shaft hole; and in specific implementation, in order to facilitate the insertion of the rotating shaft 320 into the shaft hole, the shaft hole can be provided to have an opening.
[0063] In this embodiment, as Figure 3 and Figure 4 As shown, the shaft connection assembly 110 may also include a first shaft connection block 111 and a second shaft connection block 112. The first shaft connection block 111 and the second shaft connection block 112 are respectively disposed on both sides of the circumferential direction of the rotating shaft 320 and are offset in the axial direction of the rotating shaft 320. The first shaft connection block 111 and the second shaft connection block 112 are respectively provided with a first arc groove 111a and a second arc groove 112a. The rotating shaft 320 is inserted between the first arc groove 111a and the second arc groove 112a.
[0064] In specific implementation, the shaft connection assembly 110 can be one, two or more (the attached figure shows two shaft connection assemblies as an example).
[0065] In this embodiment, in order to further improve the connection stability between the insulating clamp 300 and the insulating main frame 100, such as Figure 3 Furthermore, a limiting component 120 may also be provided on the insulating main frame 100. The limiting component 120 includes at least one first limiting block 121 and at least one second limiting block 122. The first limiting block 121 and the second limiting block 122 are respectively disposed on both sides of the circumferential direction of the rotating shaft 320.
[0066] In this embodiment, the elastic element 500 can be a compression spring or a tension spring 510, etc. In specific implementations, to improve the ease of replacing the elastic element 500, it can be set as a tension spring 510. In this case, such as... Figure 1 and Figure 3 As shown, the rotating shaft 320 is located on the side of the insulating clamp 300 away from the accommodating space, and the elastic element 500 is located on the side of the insulating clamp 300 close to the accommodating space; a first hook rod 330 and a second hook rod 130 are respectively provided on the insulating clamp 300 and the insulating main frame 100, and the two ends of the tension spring 510 are respectively hooked on the first hook rod 330 and the second hook rod 130.
[0067] In one optional specific implementation of this embodiment, such as Figure 3 As shown, the insulating clamping member 300 may include a frame-shaped body 340 and a plurality of insulating clamping arms 350 extending outward from the frame-shaped body 340 toward the periphery of the accommodating space. The ends of the insulating clamping arms 350 are provided with crimping holes 351, and the insulating clamping heads 310 are disposed in the crimping holes 351.
[0068] In this embodiment, the insulating clamping head 310 can be configured as a rubber end 311, such as... Figure 6 As shown, the rubber end 311 includes a first segment 311a, a second segment 311b, a third segment 311c, and a fourth segment 311d from its first end to its second end. The diameters of the first segment 311a and the third segment 311c are corresponding to the diameter of the crimping hole 351. The diameter of the second segment 311b is larger than the diameter of the crimping hole 351, and the diameter of the second segment 311b gradually increases as it approaches the third segment 311c. The diameter of the fourth segment 311d is larger than the diameter of the crimping hole 351. When the first end of the rubber end 311 is pressed into the crimping hole 351, the third segment 311c is located inside the crimping hole 351, and the second segment 311b and the fourth segment 311d abut against the two end faces of the crimping hole 351, respectively.
[0069] In this embodiment, the part that abuts against the object to be electroplated 400 is the fourth segment 311d of the rubber end 311.
[0070] In practice, the material of the rubber end 311 can be fluoropolymer (FPM).
[0071] The electroplated conductive fixture in this embodiment of the invention can be prepared through the following steps:
[0072] A conductive core 200 is prepared; the conductive core 200 includes a conductive arm 210 and a plurality of electrical terminals 220 disposed on the conductive arm 210.
[0073] An insulating main frame 100 is injection molded around the conductive core 200, with one end of the conductive arm 210 of the conductive core 200 protruding outside the insulating main frame 100, and the electrical terminal 220 protruding outside the insulating main frame 100; the four sides of the insulating main frame 100 enclose a space for the object to be electroplated 400, and the electrical terminal 220 protrudes outside the insulating main frame 100 at the periphery of the space; the sides of the insulating main frame 100 containing the conductive core 200 are conductive sides, and there are at least two conductive sides.

[0076] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
