Description

Technical Field

[0001] The utility model belongs to the technical field of PogoPin processing devices, and in particular relates to a PVD gold-plated clamping device for a solid pin connector. Background Art

[0002] In the surface treatment industry, especially when PVD gold plating is performed, when processing shells or other products with larger shapes, hangers and carriers are usually used for centralized operations. These hangers all have one thing in common, that is, they need to be kept conductive. When processing, the hanger carrier needs to conduct electricity to the product, so that the product remains in a conductive state for processing.

[0003] Due to the conductive properties, all products such as pin connectors (a type of PogoPin) must ensure conductivity during processing. Products cannot be stacked randomly. When clamping, they must ensure complete and independent conductive functions, and the gold-plated surfaces of the products must be in the same direction.

[0004] In addition, all PVD gold-plated products need to take the above conditions into consideration at the same time. Since some small products are small in size and have no clamping and hanging points, ordinary hangers and carriers cannot effectively position the products due to insufficient precision, and cannot be processed efficiently. In this case, steel wire is generally used to manually wind and fix the products, and multiple products are wound together using a chain, and then uniformly clamped on the hanger. Using this method, the number of product clamps is extremely small, the efficiency is low, and the production yield is also affected due to the low consistency of clamping. At the same time, due to the characteristics of PVD gold plating, products need to be accumulated into the vacuum furnace for operation. When the number of products loaded into a single furnace is small, the product processing cost is extremely high. Utility Model Content
