Detailed advantages of the contact finger of the composite watchband


Release time:

2022-06-10

The contact fingers of the composite watchband are made of high-performance and high-quality conductive materials and are manufactured through a special process. The design of a compact electrical contact structure suitable for switchgear, relying on its elastic deformation to provide contact pressure at the contact point. The contact can be made into single-point and double-point contacts, and can also be made into inserts with large contact current to carry the rated current. The dynamic and thermal stable current is widely used in the middle sliding contact of the switching equipment, as well as the contact between the moving and static contacts.

The contact fingers of the composite watchband are made of high-performance and high-quality conductive materials and are manufactured through a special process. The design of a compact electrical contact structure suitable for switchgear, relying on its elastic deformation to provide contact pressure at the contact point. The contact can be made into single-point and double-point contacts, and can also be made into inserts with large contact current to carry the rated current. Dynamic and thermal stable current is widely used in the middle sliding contact of switchgear and the contact between moving and static contacts. Positive belt contact refers to a specially shaped elastic connecting element that has been used for more than 50 years. It is a good choice for high current, high plug life and harsh working conditions. Ribbon contacts are suitable for various electrical connections of high-voltage electrical appliances and are widely used in high-voltage switches, circuit breakers, bushings and busbars.

The contact finger reed of the watchband is made of alloy copper with good elasticity and good conductivity. It is manufactured by a strictly controlled professional process and is suitable for compact electrical connections of various electrical equipment. Relying on the elastic deformation of each contact unit to provide contact pressure, can be made into a single point contact, double point contact or mosaic contact, with a stronger current, to carry different requirements of the rated current, dynamic, thermal stability current. The current of the strip contact spring varies from tens of amperes to thousands of amperes. It has the characteristics of small contact resistance, simple structure and good reliability. It is widely used in various high-current connection occasions.


The mounting strip on one side of the contact finger connecting strip of the composite watchband is embedded in the first embedding groove, the side wall of the first embedding groove is bent to cover the mounting strip, and the mounting strip on the other side of the connecting strip is embedded in the first embedding groove. the second embedding groove, the side wall of the second embedding groove is bent to cover the mounting strip. The growing energy demand and the corresponding capacity expansion of the existing grid require efficient and reliable equipment. Miniaturization of installation space and systems requires that the size of equipment and components be reduced without affecting performance. At the same time, energy suppliers and power plants are very concerned about their operating and maintenance costs.


The challenge for the contact fingers of composite watchbands is to provide customers with reliable high-power equipment while maintaining economy. The company is committed to improving design solutions and is always looking for space-saving, stable and high-performance contact elements. The contact fingers of the composite watchband are made of high-elasticity beryllium bronze alloy material, which has excellent conductivity and high elasticity. It is suitable for various circuit breakers, cable accessories, bus bars, and high-current industrial connectors. Typical applications are ZW20 column vacuum circuit breaker, fuse box, 35KV cable plug, insulating sleeve, high current connector, etc. It can also be used for data transmission, fiber optics, coaxial applications and photovoltaics.


Composite watchband touch finger features: small size, simple structure, no pressure spring, more electric shock, large current capacity, high reliability, stable contact pressure, fatigue resistance, convenient installation, long service life, wear resistance, wide finger, thickness series change.
