Instructions for use of the touch fingers of the composite watchband


Since the development of photovoltaic industry, technological innovation has emerged in an endless stream. For the composite strap touch finger, after two generations of change, perhaps "stability" is the way to development. "Stability" means reliability and safety, which is closely related to the technical level and experience of the splicing equipment manufacturer in electrical connection. As a conductive medium, the strip-like reach is a special-shaped elastic assembly element, which can significantly improve the quality of electrical assembly and energy transmission, so that the splicing device has a consistent low resistance. Before the emergence of the contact fingers of the composite watchband, the group of photovoltaic power plants was mainly successful through "splicing" (threaded terminals or splicing equipment). With the development of the industry, the demand for fast, safe and easy-to-operate group connection solutions is increasing.

In 1996, a new type of plug-in splicing device came into being, the Stäubli MC3 composite strap touch finger. MC3 is a photovoltaic assembly products. "Splicing" is two completely different groups of ways. Its significance is to redefine the assembly of photovoltaic modules. In 2002, the Storybill MC4 went on the market, redefining the touch finger of the composite strap and successfully "plug and play". With the increasing requirements of photovoltaic power plant systems, the emergence of MC4 and its replacement of MC3 are inevitable, both from the standard level and from the safety level. Since MC4 was developed and put on the market in 2002, it has been successfully applied for nearly 17 years and has gradually become the industry standard. At present, there are many types of splicing equipment products on the market, but most of them adopt styles in structure and appearance, so we can call them "similar to MC4".


The reach reed of the composite watchband is a reach unit that acts between the socket contact and the pin contact to reliably transmit current. The finger reed is basically made of beryllium copper alloy. A bar finger spring acts on the split device. It has good elasticity and excellent conductivity, can be successfully highly reliable mechanical and electrical assembly.


By changing the type of the finger spring of the composite watchband, the splicing equipment with various characteristics can be successfully assembled: low-resistance splicing equipment, long-life splicing equipment, splicing equipment with large gap between plug and socket diameter, and easy-to-plug splicing equipment.


The shutter structure acts to transfer a large current. Multi-point to achieve stable power supply. Even at high currents, low attainment resistance can control heating. The oxide film is removed by thermal cycling. The heat-resistant and corrosion-resistant ribbon finger spring can be manufactured by changing the material. Not only sockets can be installed, but also plugs can be installed. Ribbon finger reeds can be sold separately for large-scale applications.


The above is about the application of such products. At present, our domestic market still has a lot of room for growth and great potential in the future.
