Abstract
Description
Technical Field
[0001] This utility model relates to the field of electroplating equipment technology, specifically to a relative dovetail spring-loaded electroplating hanger contact device. Background Technology
[0002] Plastic electroplating racks often experience unstable conductivity at the hanging points. Due to uneven stress on the product on the rack, current breakdown or yellowing of the plastic product occurs at the hanging points, severely affecting the quality of the electroplated product. The main reason is that the design of the electroplating rack contacts lacks effective measures to increase conductivity and cannot maintain continuous conductivity. At the same time, the rack contacts cannot grip the plastic product tightly, causing the product to yellow and reducing the quality of the electroplated product. Utility Model Content

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.
[0027] Please see Figure 1-5 This utility model provides a relative dovetail spring-loaded electroplating hanger contact device, including a support 1, a limiting support rod 2 fixed in the middle of the support 1, a straight needle 3 fixed on the upper end face of the limiting support rod 2, a spring-loaded contact plate 4 fixed on the lower end face of the limiting support rod 2, a left bracket 5 fixed on the left end of the support 1, a right bracket 6 fixed on the right end of the support 1, a left dovetail clamp 7 fixed on the left bracket 5, and a right dovetail clamp 8 fixed on the right bracket 6.
[0028] The spring-loaded contact plate 4 includes a straight plate 41, which is fixed to the lower part of the end face of the limiting support rod 2. A V-shaped plate 42 is fixed on the straight plate 41, and a right-angle groove 43 is formed by the V-shaped groove above the V-shaped plate 42. An inclined plate 44 is fixed on the V-shaped plate 42.
[0029] The left support 5 includes a left straight rod 51, which is fixed to the left end of the support 1. A left bent rod 52 is fixed on the left straight rod 51. The right support 6 includes a right straight rod 61, which is fixed to the right end of the support 1. A right bent rod 62 is fixed on the right straight rod 61.
[0030] The left dovetail clamp 7 includes a left dovetail groove 71, which is located on the inner side of the left dovetail clamp 7. The right dovetail clamp 8 includes a right dovetail groove 81, which is located on the inner side of the right dovetail clamp 8. The operator inserts the pins of the electroplated product into the left dovetail clamp 7 and the right dovetail clamp 8, inserting the pins into the straight pin 3. This makes the clamping more secure. The spring-loaded contact plate 4 enhances the conductivity of the product and ensures product quality.
[0031] Furthermore, both the left dovetail clamp 7 and the right dovetail clamp 8 have a diameter of 3.0mm and are machined into a dovetail shape. The dovetail joints are flattened and hemped to facilitate a more stable clamping of the product by the left dovetail clamp 7 and the right dovetail clamp 8.
[0032] Furthermore, the straight needle 3 has a diameter of 3.0mm, and the front end is flattened and roughened. Flattening can increase the surface area, remove oxide layers or impurities, and make the electroplated layer adhere more firmly to the substrate. Roughening is achieved through chemical etching, mechanical polishing or electrical discharge machining. This roughening treatment can improve the adhesion of the plating layer, and may also be used to hide substrate defects or achieve a specific matte effect.
[0033] Furthermore, the spring-loaded contact plate 4 has a diameter of 3.2mm, with the front end flattened and bent at 90 degrees to form a "V" shape and the middle section being arc-shaped. The spring-loaded contact plate 4 is pressed onto the straight pin 3. The spring-loaded contact plate 4 is sheet-shaped, which makes the contact area between the spring-loaded contact plate 4 and the product pin larger, the clamping more secure, and enhances the conductivity of the product, resulting in better performance.
[0034] Furthermore, the left dovetail clamp 7 and the right dovetail clamp 8 are symmetrically arranged, which can apply pressure to the product from both sides, making the force more even.
[0035] Furthermore, both the left dovetail groove 71 and the right dovetail groove 81 are acute-angled V-shaped, which allows the left dovetail clamp 7 and the right dovetail clamp 8 to limit the left and right wobbling of the product pins.
[0036] Furthermore, the straight pin 3 is located inside the left dovetail groove 71 and the right dovetail groove 81. When the pin of the electroplated product is inserted into the straight pin 3, the electroplated product is located between the left dovetail groove 71 and the right dovetail groove 81 on both sides, which makes it convenient for the left dovetail clamp 7 and the right dovetail clamp 8 to apply pressure to the electroplated product together.
[0037] Furthermore, the inclined plate 44 is set to be tilted outward and is located at the outer end of the spring-loaded contact plate 4, so that when the pins of the electroplated product are inserted into the straight pin 3, they will not interfere with the inclined plate 44.
[0038] In use, the support 1 is first fixedly connected to the external electroplating equipment so that the support 1 can play a supporting role. Then, the operator inserts the pins of the electroplating product between the left dovetail clamp 7 and the right dovetail clamp 8, and inserts the pins into the straight needle 3. The limiting support rod 2 can prevent the product pins from being inserted too deeply. At the same time, the left dovetail clamp 7 and the right dovetail clamp 8 apply pressure to the electroplating product inward, and the force is more even. This allows the left dovetail clamp 7 and the right dovetail clamp 8 to limit the left and right swaying of the product pins, and clamp them more firmly. This prevents the product from experiencing current breakdown or yellowing of plastic products at the hanging point due to uneven force on the electroplating rack. In addition, the spring-loaded contact plate 4 can firmly hold the product pins and enhance the conductivity of the product, thereby effectively ensuring conductivity and improving the product processing quality.
[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
