BNC connector as an important component of equipment and equipment BNC connector, whether it is made of copper or zinc alloy, has a similar appearance. It is used in monitoring projects. A 16-in 32-out distributor has 48 BNC female sockets. A large matrix has hundreds of BNC female sockets, and a larger monitoring project uses thousands of BNC connectors. 1% of defective products will cause more than ten failures. Large projects use poor quality BNC connectors. After-sales service will be very troublesome. Its quality directly affects the effect of the project, but it is easy to be overlooked. BNC connector failures are usually good and bad. Common failures that appear in monitoring projects are sometimes images and sometimes no images, or Unidentified image interference, image quality degradation, etc., and even some strange faults or problems occur after a period of time, occupying a lot of time for engineering personnel to troubleshoot faults.
BNC radio frequency connector is the data transmission interface of many multimedia products, and it is widely used.
With the increasingly fierce competition in the industry, various choices of bnc connector materials have appeared. Generally, a good bnc connector requires good conductivity in terms of metal material. Copper is the most conductive metal. However, because the price of copper itself is relatively high, the use of pure copper is relatively rare now.
In addition, copper itself is easily oxidized, which is not conducive to contact transmission, so it is necessary to coat the surface with oxidation-resistant metals, such as zinc, silver, tin, etc.
The best bnc connector on the market now is that the metal is made of pure copper galvanized or silver, with good PVC plastic parts, so that the entire BNC connector can achieve a good conductive part.
When the BNC male connector is in contact with the BNC female connector, the BNC connector male connector is in contact with the outer layer of the female connector through the second layer of the male connector, so the second layer of the high-quality BNC male connector is copper, high-quality The outer layer of the female header is copper.
Because the characteristics of copper and zinc alloys are different, the production process is also different. Although the appearance of the finished product is similar, the processing technology is different and easy to identify. Copper is easier to process and can be finely processed with a CNC lathe. Zinc alloy is not. The copper BNC female seat is automatic There are no traces of processing on the lathe, but no traces of the zinc alloy
Generally, it is difficult to identify its quality without certain skills. The BNC male connector is generally easy to purchase by the engineering company. The female connector is generally installed on the equipment and is often easily overlooked.
BNC connector quality:
- From the surface of the product, the BNC connector should be bright and delicate. The higher the purity of the copper, the brighter it is. Some products are bright on the outside, but they are made of iron.
- In the adsorption test of iron absorption stone, in general, only the bayonet spring and tail spring are made of iron material; the wire clamp, pin and sleeve are made of copper, and the other parts are made of zinc alloy
- Scrape the surface coating to see the material: use a sharp tool such as a blade to scrape the surface coating to see the material intuitively, and compare the product material intuitively by scraping the coating of wire clips, pins, and shielding sleeves.
- In addition to the above methods, you can also prepare a good quality female head to try.
