What are the advantages of ultra-small waterproof connectors
Waterproof connector is a kind of electronic components with waterproof function for working in water. Power cords, network cables, etc. can be placed inside them. Not only can they provide normal and safe and reliable power, signal transmission, but also the most important and characteristic function. It has a good waterproof and dustproof effect.
At present, the main evaluation standard for the waterproof performance of waterproof connectors is based on the IP waterproof rating standard. To see how the waterproof connector is waterproof, it mainly depends on the two digits XX behind the IPXX connector. The first X is from 0 to 6, the highest level. It is 6, the second digit is from 0 to 8, and the highest level is 8, so the highest waterproof level of the waterproof joint is IP68.
Advantages of ultra-small waterproof connector
With the development of technology, many things in our lives now use electricity, but more or less charged things will have a certain impact on our safety, so waterproofing is very important, and waterproof connectors can be applied to environments with water. It has excellent sealing performance of components and reliable waterproof performance. For example, if some equipment is to enter the water or be installed underwater, then use the waterproof connector to avoid worrying about the connector due to water, especially water containing more chemicals. The problem of damage to machinery and equipment.
The emergence of waterproof connectors can be said to be a great boon for us. It is widely used. I need to use waterproof connectors in many fields, such as industrial environments, such as LED lighting, urban outdoor lighting projects, lighthouses, and cruise ships. , Aviation, industrial equipment, cables, sprinklers, etc., all need to use waterproof connectors. Due to strict application requirements in the military field, a large number of waterproof connectors are used, such as connectors for submarines, connectors for submarine-launched missiles, etc. .
With the transition of the microwave industry from international applications to the commercial field, the demand for compact and high-density systems has grown. This development trend in the microwave industry has placed requirements on the connector mechanism for electronic connectors, that is, not only must work well at high frequencies , And must be plugged and unplugged in a blind mating environment.
For many years, microwave engineers working in the K-band and higher frequency range have been limited to using conventional connector interfaces such as SA4A. Such limitations are due to the size of the interface and the need to enter the interface area for mating and unplugging the connector. Caused the complexity of packaging.
The ultra-small push-in (SMP) interface is designed to alleviate the traditional industrial connector problem with the microwave connector. It can be plugged and unplugged in blind mating, so there is no need to enter the mating interface. SMP connector It is much smaller (about 50%) than the SMA connector, so the package size can be reduced overall.
The materials used in the structure of the SMP connector series are bronze and polytetrafluoroethylene, and bronze is used for the shell and inner conductor. Both are heat-treated and gold-plated to achieve the necessary material properties. The dielectric material is polytetrafluoroethylene. , This board provides good performance for the combination of boards, including high mustache and mechanical mating performance.
The development of this interface is the result of a requirement issued by the National Defense Electronic Equipment Supply Center (}DESC) to the manufacturer. This requirement requires the manufacturer to participate in the specification of the interface size of the SMP connector. There is a requirement that the interface should be in line with the GPO( Commodity name) connectors are interchangeable. The performance criterion requires a radial deviation of ± 0,508 mm (earth 0.02 inch) and a pin direction deviation of 0,254 mm (001 inch). Extensive tests have been carried out at DESC to verify the mutual The electrical and mechanical properties of the interchangeability and interface.
Blind-mate connectors have many obvious advantages. The microwave subsystems can be combined in a manner similar to toy assembly. The i-like structure eliminates the size, weight, and common threaded connector interconnection methods. For related issues, microwave motherboards have become more practical. Multiple connections on the female side of a row of components do not require wiring. The size and frequency of the connectors are up to the GH' performance, making them suitable for sealed systems' and Become an ideal choice.
In short, the design and development of SMP connectors provide a much-needed solution for the high-level packaging situation.'They represent an obvious breakthrough in blind mating microwave connectors. Such blind mating capability plus common high-sales performance This makes Liu Fu Microwave Packaging Engineer of Da kind of connector especially attractive.
