High Precision Solid Contact Charging Pin

High Precision Solid Contact Charging Pin

The charging contacts (solid pins) can be divided into three types: flat bottom type, plug-in type, and wire-bonding type according to the welding type.

We provide high-precision charging contact (solid Pin) car parts and connectors of various structures, which are used in conjunction with pogo pins, which are widely used in smart wearable fields such as TWS earphones, and watch bracelets, etc., fully satisfying the needs of different customers. Appearance, assembly, corrosion resistance, and other requirements.

We have more than 80 automatic precision lathes, mainly including the Japan STAR core moving machine, and Taiwan Ming yang cutting machine, with mature and stable manufacturing technology to provide High Precision Lathe hardware.

Providing customers with better service and guaranteeing the quality, our electroplating workshop has many mature and stable plating processes, including composite plating, and hybrid plating. Conventional plating processes such as Plating copper, nickel, tin, silver, gold, palladium, and rhodium have been mass-produced.

Assembly workshop:

There are complete production and assembly capabilities, from riveting assembly to packaging and taping. Professional technical team, stable technical support.

Production Testing Equipment:

We inspect length, height, diameter, mixing, deformation, lack of material, burrs, black spots, scratches, Rohs, etc.

Quality Assurance System

The system documents are complete, and each process is identified and defined in the form of program documents;

The production documents and quality control documents are complete, and the product size and key parameters of the first article and inspection are operated, confirmed, and recorded by the requirements of SIP and SOP;

There will be several metal points on the TWS headset, and there will be several retractable contacts on the corresponding charging compartment. This is the pogo pin (spring pin) component to be introduced today. Conducts current or electrical signals.

What's so special about using contacts on this? Not to mention, it is different from the ordinary TWS headphones. The two most critical points are mentioned above: waterproof and sweat-proof. Because of sports, you will sweat. At this time, wearing headphones will inevitably cause sweat on the headphones. These contacts are connected to the power supply. When there is water between the contacts, it will cause electrolysis.

If these contacts (solid pin) ) surface coating does not have electrolysis resistance, so after a few times of use, the surface plating of the contacts will be gradually electrolyzed off, which will cause poor contact of the contacts, and may not be charged or fully charged.

To solve the above problems, we have independently developed the "special coating" technology, which can be dealt with loosely.
