Description

Technical Field

[0001] The invention belongs to the technical field of hangers, and in particular relates to an electrical connector chemical plating hanger and a processing method thereof. Background Art

[0002] With the rapid development of chemical plating solution formula and equipment, the stability of chemical nickel plating mass production has gradually matured. Because its coating has good uniformity and consistency, and has different mechanical and environmental resistance properties according to different phosphorus contents, connectors using this technology are widely used in aerospace, aviation, shipbuilding and other fields. Chemical plating technology does not require electricity, so there is no conductivity requirement for the hanger. At present, many connector manufacturing companies have adopted two main production measures: Method 1, using aluminum wire for wire binding and hanging plating for aluminum alloy parts; Method 2, designing a proprietary hanger, using stainless steel materials to form a coating using water glue and green glue.

[0003] The above two methods mainly exist as follows:

[0004] Method 1: The efficiency of chemical nickel plating for aluminum alloy electrical connector parts is low, it relies on the skills of operators, there are wire binding marks caused by jamming in the wire binding area of ​​parts during the production process, and the long-term use of aluminum wire or enameled wire leads to increased costs.

[0005] Method 2: The main problems with chemical nickel plating of aluminum alloy electrical connector parts are that the water-based glue and green glue are heavy, the production quantity of each hanger part is limited, the operation is difficult, and it is not resistant to high temperatures and is not suitable for automatic baking on a fully automated production line.

[0006] The patent document with the announcement number CN114775026A discloses a flexible high-order circuit board electroplating transfer rack, which includes a crossbeam, a support frame is provided at the front end of the crossbeam, a conductive frame is fixed at the lower end of the support frame, and a plurality of upper conductive clamps and a plurality of lower conductive clamps are provided on the conductive frame. The rack is different from the present application in that it solves technical problems through Teflon spraying of the conductive frame and U-shaped support flat and tin bronze conductive copper. It is unclear whether the rack is suitable for mounting in high temperature processing.

[0007] The patent document with announcement number CN201971914U discloses a gold-plated hanger for circuit boards, including a main frame and a plurality of hooks arranged on the main frame, and a Teflon sleeve is arranged on the periphery of the main frame. The main frame of this product is provided with a Teflon sleeve, which can make the hanger more resistant to high temperatures and acid and alkali, but the hanger head of the hanger is not provided with a structure fastened to the mounting platform.
