Abstract
Description
Technical Field
[0001] The utility model relates to a cathode ball tooling for capacitor electroplating, belonging to the technical field of capacitor electroplating. Background Art
[0002] The capacitor ends usually need to be plated with a protective layer and a solder layer to achieve the corresponding functions, such as nickel-tin, copper-tin, nickel-tin-lead, etc. The electroplating process is an oxidation-reduction reaction of metal ions under the action of an electric field. The metal to be plated on the product is used as the anode (positive electrode), the product to be plated is used as the cathode (negative electrode), and the plating solution containing the corresponding metal ions is used as the medium. In the electroplating process, it is usually necessary to use a section of wire to connect a metal ball as the cathode (negative electrode) to conduct electricity to the product. The cathode ball mainly serves to increase the contact area of the product. In order to ensure the conductive effect, the metal ball is usually welded to the wire. The welding position often has problems such as excessive metal growth and sticking. After a period of time, the cathode ball and the wire are tightly plated together and cannot be separated. The electroplating liquid will also penetrate into the inside of the wire, resulting in the wire cannot be used again, resulting in a waste of labor costs and material costs. Utility Model Content

[0004] The technical solution adopted by the utility model is a cathode ball tooling for capacitor electroplating, comprising a conductive rod, a cathode ball and a gasket, one end of the conductive rod is detachably connected to the cathode ball, the gasket is installed between the conductive rod and the cathode ball, and the gasket is made of polyurethane.
[0005] Furthermore, the conductive rod is made of brass, both ends of the conductive rod are provided with external threads, and the middle part of the conductive rod is sealed with resin.
[0006] Furthermore, the cathode ball is made of brass and is provided with an internal threaded hole for connecting with the conductive rod.
[0007] The utility model discloses a cathode ball tooling for capacitor electroplating, and its beneficial effect is that compared with the prior art, the utility model solves the problem of sticking and other quality risks caused by uneven growth of metal plating on the cathode ball during capacitor electroplating by arranging a conductive rod, a cathode ball and a gasket to cooperate with each other, reduces the difficulty of replacing the cathode ball and the material cost, ensures that the plating on the cathode ball is uniform, and the cathode ball can be used repeatedly, thereby improving the electroplating quality and reducing the cost.

[0015] like Figures 1-2 As shown, this embodiment provides a cathode ball tooling for capacitor electroplating, including a conductive rod 1, a cathode ball 2 and a gasket 3. The conductive rod 1 is made of brass, with external threads at both ends of the conductive rod 1, and the middle part of the conductive rod 1 is sealed with resin; the cathode ball 2 is made of brass, and an internal threaded hole 6 is provided on the cathode ball 2; the gasket 3 is put on the conductive rod 1, and the conductive rod 1 is screwed into the cathode ball 2, and the gasket 3 is made of polyurethane.
