Heavy-duty connectors with poor contact problems

The plug of heavy duty connector has both low frequency and high frequency, I will give you a brief introduction. In terms of frequency, the plug of heavy duty connector, i.e. aviation plug is characterized by low frequency and high frequency. When choosing low-frequency electrical connectors, the first thing to consider is the electrical parameters, followed by the selection of rated voltage and rated current according to different use environments and safety requirements, for multi-core connectors, the rated current must be reduced in order to be used, and lastly, the selection of the mounting method and shape. So what is the installation method and appearance? Heavy-duty connectors have a wide variety of terminal shapes. We mainly choose from straight line shape, curved shape, outer diameter of wires and cables as well as fixing requirements of the housing, volume, weight, and whether or not metal hoses are connected. For electrical connectors used on panels, we also choose from aesthetics, shape, color and other aspects. Today's heavy-duty connector is the continuous development and innovation, the development of new materials, new technologies, manufacturing resource-saving environmentally friendly enterprise products, are used in extreme harsh use of the network environment, so that the production of technological equipment connected to a more tightly, firmly.

Heavy-duty connectors are widely used in construction machinery, textile machinery, packaging and printing machinery, tobacco machinery, electric locomotives and petrochemical electrical equipment that require electrical and signal connections. It can improve the installation efficiency of pre-installation, as well as the effective utilization of equipment space, while providing a more secure connection for the robust and secure housing. It can also deal with extreme weather conditions and provide effective protection in harsh environments such as dust, rain, cold, snow, ice, oil and other harsh environments, such as heavy-duty connectors that are also widely used in the railroad industry. Heavy-duty connector is also an industrial technology products, since it is a connector, then need to overcome is through the contact society bad problem, this environmental problem analysis of our domestic should be the first to understand the causes of poor contact is which? First of all, the oxidation of the metal surface and impurities can lead to poor contact society, exposed to the air metal, will get to meet the different cultural degree of oxidation, oxidation and metal materials, environmental development conditions, placed in a close combination of time relationship related. Then we have an oxidized layer, the actual problem of effective contact surface becomes smaller, it will cause contact some bad. Secondly, the air contains a lot of dust, dust, all kinds of smoke, exhaust fumes, debris, etc., although many invisible to the naked eye, but for heavy-duty connectors, these substances cover the metal surface, will also affect the actual effective contact surface becomes smaller, resulting in poor contact. There are also causes of pressure and deformation. Heavy-duty connectors in the installation and use of the process of inserting the convex body into the concave body, the insertion and extraction process is also the process of contacting uneven surfaces, so under a certain pressure, the concave surface and convex surface contact between the deeper, some convex body under pressure will be deformed, become less prominent, so that it is possible to make contact with each other around the lower area, so in fact, the magnitude of the pressure is ultimately affected by the actual effective surface contact area of the impact. It is also due to poor contact.
