[0043] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the following specific embodiments further describe the utility model in detail. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0044] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0045] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0047] In the description of the embodiments of the present utility model, it should be noted that if the terms "upper", "lower", "horizontal", "inner", etc. indicate an orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed when in use, it is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0048] In addition, if the term "horizontal" appears, it does not mean that the component must be absolutely horizontal, but can be slightly tilted.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0050] The utility model is further described in detail below with reference to the accompanying drawings:

[0051] Example 1

[0052] Combined with what is mentioned in the background technology, at present, most of the silver-plating tools used for silver-plated parts use hook-type hangers, each hook hangs a part, and the part relies on its own gravity to hang. When silver-plating, the part to be silver-plated needs to be immersed in an electrolyte containing silver salt and additives. Due to the influence of solution buoyancy and solution shaking, the hook is easy to have poor contact with the part or even detach, resulting in poor conductivity during the silver-plating process, affecting the first-time pass rate of silver plating; at the same time, the hook-type hanger has a large exposed area, and the main silver material is wasted. In other words, the existing silver-plating tools have the following shortcomings:

[0053] 1. At present, the silver-plating tooling adopts hook suspension, which cannot guarantee the reliable conductivity of the silver-plating process. At the same time, the contact area of ​​the hanger is large, resulting in unnecessary waste of the main material silver.

[0054] 2. Different parts are hung with simple hooks made of hard aluminum strips or aluminum wires. The silver plating efficiency is low, and the hard aluminum strips will become soft after repeated silver fading and cannot be used anymore, so the service life is short.

[0055] 3. The existing silver-plating tooling uses screws to tighten parts for conductivity. After silver plating, the threads will also be plated with silver, making it difficult to remove the parts after they are offline.

[0056] In order to solve the above problems, the present embodiment provides a plug-in silver plating tool, which is particularly suitable for silver plating of parts with holes within φ20; the tool adopts a load-bearing and conductive separation method for the entire tool, which improves the quality of the silver layer, reduces the useless consumption of plating materials, and improves the one-time qualified rate of parts silver plating; the use of this tool not only ensures reliable conductivity, but also improves the silver plating production efficiency, and at the same time has the advantage of a small hanger contact surface.

[0057] In order to better understand the technical solution of the utility model, the following terms are first explained:

[0058] Load-bearing hanger: A component of the silver-plated tooling, used to place and fix the hanger body and also has the conductive function of cathode current.

[0059] Conductive joint: The conductive connection between the hanger and the parts, which plays a conductive role in the silver plating process.

[0060] Conductive beam: acts as cathode during silver plating and supports the suspension of the hanger.

[0061] Silver removal: A common operating step in the electroplating process. After the parts are silver-plated, nitric acid is needed to dissolve the metallic silver on the hanger. The clean hanger can be reused for the next silver plating.

[0062] like Figure 1As shown, this embodiment provides a plug-in silver-plating tool, including a load-bearing hanger 1 and a conductive connector 3, wherein the conductive connector 3 is connected to the load-bearing hanger 1 through a threaded hole 2 on the load-bearing hanger 1.

[0063] like Figure 2 As shown, the conductive joint 3 includes a connecting bolt 3-1 (made of stainless steel), a copper mesh wire 3-2 and a stainless steel elastic structural member 3-3 which are connected in sequence.

[0064] The U-shaped hook 1-1 of the load-bearing hanger 1 is used to suspend and fix the load-bearing hanger 1 to the conductive beam of the silver-plating production line, and has a cathode conductive function. The conductive connector 3 is connected through the threaded hole 2 on the load-bearing hanger 1, and different combinations of conductive connectors 3 and the load-bearing hanger 1 can be realized. The stainless steel elastic structure 3-3 at the end of the conductive connector 3 is inserted into the conductive hole 4-1 of the silver-plated part to realize the silver-plating operation of different parts.

[0065] like Figure 3 As shown, specifically Figure 3 In (a) and (b), in this embodiment, the load-bearing hanger 1 is welded into one body by the hook 1-1, the conductive copper plate 1-2, the spring 1-3 and the hanger body 1-5; the hook 1-1 is hung on the conductive beam, and then fastened by the stainless steel fastening bolt 1-4, and the hook is fastened to the conductive beam by the spring 1-3. The setting of the spring 1-3 facilitates the hanging of the hanger body 1-5 and improves the fastening performance; the stainless steel fastening bolt 1-4 further ensures the reliability of the fastening to the conductive beam.

[0066] The load-bearing hanger 1 is made of stainless steel, and the hanger body 1-5 is protected by insulating protective coating; the threaded hole 2 adopts a nut welding structure, and here, the threaded hole 2 can also be formed by opening a hole in the hanger body 1-5.

[0067] More specifically, the hook 1-1 of the load-bearing hanger 1 is made of stainless steel and lined with a conductive copper plate 1-2. The conductive copper plate 1-2 is made of red copper plate, and the connection part with the conductive beam is red copper. After hanging, it is fastened with stainless steel fastening bolts 1-4 to ensure that the overall conductivity of the hanger is reliable.

[0068] Another example Figure 3 As shown in (a) and (b), the load-bearing hanger 1 is arranged in layers, and each layer is an integral load-bearing frame. Figure 3 A square frame structure is adopted, and multiple parts to be silver-plated can be placed in the integral load-bearing frame.

[0069] like Figure 7 and Figure 8 As shown, Figure 7This is a schematic diagram of the stainless steel elastic structural member 3-3 before being placed into the parts. It can be seen that the stainless steel elastic structural member 3-3 adopts a U-shaped structure, and the U-shaped structure is gradually expanded from the arc to the openings at both ends, so that it has good elastic properties; Figure 7 The vertical line of the U-shaped structure in the figure is 21° to the end c; Figure 8 This is a schematic diagram of the stainless steel elastic structural member 3-3 after being placed into the part. Under the external force of the conductive hole 4-1, the angle becomes 9° at this time; the U-shaped structure shrinks inward and has a rebound tendency, so that it is fastened to the conductive hole 4-1, ensuring a reliable connection.

[0070] Specifically, the stainless steel elastic structural part 3-3 is made of 06Cr19Ni10 stainless steel material. Due to the elasticity and special structure of stainless steel, the stainless steel elastic structural part 3-3 is fixed in the conductive hole 4-1 of the part to be silver-plated, which can meet the conductivity reliability of silver plating and avoid the problem of low silver plating qualification rate caused by poor conductivity. The U-shaped structure and the gradually expanding opening from the arc to the two ends further ensure the reliability of the plug-in method and improve the reliability of the connection between the stainless steel elastic structural part and the inner wall of the conductive hole of the part.

[0071] Of course, this is not limited to the U-shaped structure, and any structural member that can make the stainless steel elastic structural member 3-3 have good resilience performance can be used.

[0072] This embodiment provides a plug-in silver-plating tool, and the specific working process is as follows:

[0073] During operation, the hook 1-1 of the load-bearing hanger 1 is hung on the conductive beam of the silver-plating production line, and the connection is fastened with a stainless steel fastening bolt 1-4. After the conductive joint 3 is connected to the threaded hole 2 on the load-bearing hanger 1 through the connecting bolt 3-1, the silver-plated part is placed in the load-bearing hanger 1, and the stainless steel elastic structure 3-3 of the conductive joint 3 is pinched and inserted into the conductive hole 4-1 of the part. The stainless steel elastic structure 3-3 is used to achieve reliable conductivity between the hanger and the part, and after each part is inserted into the conductive joint 3, the silver-plating operation can be performed. After the silver-plating is completed, the stainless steel elastic structure 3-3 of the conductive joint 3 is pinched and taken out, and then the silver-plated part is taken out from the load-bearing hanger 1 to complete a silver-plating operation. After the conductive joint 3 on the load-bearing hanger 1 is removed through the threaded hole 2, the silver-plating is performed, and the silver-plated conductive joint 3 is reconnected to the load-bearing hanger 1 through the threaded hole 2 and can be used again. By connecting the conductive joint 3 to different load-bearing hangers 1, the silver-plating operation of different parts can be satisfied.

[0074] It should be noted that by coating the surface of the hanger body with insulating protective paint, and coating the surface of the copper mesh wire with insulating protective paint, a large area of ​​insulation protection is achieved for this tooling, and the exposed part is only the stainless steel elastic structural part in contact with the inner wall of the conductive hole of the part, which reduces the exposed area of ​​the overall tooling and saves the consumption of silver, the main material for electroplating.

[0075] It can be seen that the conductive reliability of the silver plating process is guaranteed by the stainless steel elastic structure, and the load-bearing and conductive functions are separated during the silver plating process, avoiding the problem of low silver plating pass rate caused by poor conductivity during the silver plating process. This tooling is used for silver plating of silver-plated parts (including parts with holes) of high-voltage electrical products in the electroplating tank. It mainly solves the problem that the silver-plated parts rely on gravity to hang during the electroplating process and some parts have poor conductivity, resulting in unqualified silver plating. On the premise of ensuring the conductive reliability of silver plating, it can improve the silver plating efficiency, reduce the silver plating area of ​​the hanger, improve the quality of the coating, and reduce the loss of the main silver plating material.

[0076] Example 2

[0077] like Figure 4 As shown, specifically Figure 4 (a) and (b) in the figure, this embodiment provides another load-bearing hanger for plug-in silver-plating tooling, and its basic structure is the same as that of embodiment 1, except that the load-bearing hanger in this embodiment adopts a layered independent load-bearing frame structure. When in use, separate parts to be silver-plated are placed in each independent load-bearing frame, which can meet the needs of various silver-plating working conditions.

[0078] In addition, if Figure 5 As shown, in this embodiment, another structure of the conductive joint 3 is provided, which is as follows:

[0079] The conductive joint 3 is connected by a copper mesh wire 3-2, and the outside is protected by an insulating protective coating. One end is fastened in the first stainless steel wire clamp 3-4, and the first stainless steel wire clamp 3-4 is fastened to the stainless steel connecting bolt 3-1 through the first nut 3-5. The other end is connected to the copper mesh wire 3-2 and the stainless steel elastic structure 3-3 by a second stainless steel wire clamp 3-7 and a second nut 3-6. Both ends of the copper mesh wire 3-2 are tightly matched with wire clamps, which ensures that the connection of the stainless steel elastic structure 3 is reliable and the conductivity is good.

[0080] like Figure 6 As shown, in the embodiment, another structure of the conductive joint 3 is provided, and the end of the connecting bolt 3-1 is connected to three groups of copper mesh wires 3-2 and a stainless steel elastic structural member 3-3, forming a one-to-three conductive joint 3, thereby improving the working efficiency of silver plating.

[0081] From the above, it can be seen that the core points of the utility model are:

[0082] 1) The overall tooling adopts the load-bearing and conductive separation method to improve the first-time pass rate of silver plating.

[0083] 2) A method of connecting the copper mesh wire to the stainless steel elastic structure was designed, and the conductive holes of the silver-plated parts were used to fix the stainless steel elastic structure in the holes. This solved the problem of poor conductivity during the silver plating process and achieved reliable conductivity during the silver plating process.

[0084] 3) Combined structure, load-bearing hangers and conductive connectors can be freely combined to achieve universal use of different silver-plated parts.

[0085] 4) The whole tooling adopts insulation protection, and the exposed part is only the stainless steel elastic structure that contacts the inner wall of the part hole, which reduces the exposed area of ​​the hanger and saves the consumption of the main material silver for electroplating.

[0086] In summary, the utility model provides a plug-in silver-plating tool, which has the following advantages compared with the existing plug-in silver-plating tool:

[0087] First, the tooling adopts a method of separating load-bearing and conductive functions, which avoids the poor conductivity of parts during the silver plating process caused by the conduction of gravity.

[0088] Second, the conductive joint adopts a connection method of tight fit between copper mesh wire and stainless steel elastic structure. The stainless steel elastic structure uses the special structure and the elastic force of stainless steel to make the parts conductive during the silver plating process, and the contact area is very small, which not only ensures the reliability of conductivity during the silver plating process, but also reduces the exposed area and reduces the ineffective plating material consumption of the hanger.

[0089] Thirdly, the load-bearing hanger and the conductive joint are connected by threads and the outside is protected by insulating material, so that different combinations of conductive joints and load-bearing hangers can be realized.

[0090] Fourth, the hook of the load-bearing hanger is tightened by springs and stainless steel screws, and the conductive copper plate lined inside is in contact with the conductive beam, ensuring the reliable conductivity of the entire hanger.

[0091] Fifth, the entire tooling is coated with insulating material and can be reused. After silver plating, you only need to unscrew the conductive connector and desilver the exposed stainless steel part before it can be used again. This changes the previous operation method of removing the entire hanger for desilvering, thereby improving the silver plating efficiency.

[0092] The above embodiment is only one of the implementation methods that can realize the technical solution of the utility model. The scope of protection required by the utility model is not limited only to this embodiment, but also includes within the technical scope disclosed by the utility model, any changes, replacements and other implementation methods that can be easily thought of by any technician familiar with the technical field.
