A brief description of basic power connectors

Power connectors vary in size from small batteries to large power grids, thus allowing different ways of power transmission. Depending on the current installed and the purpose of use, one of the following types is most suitable. In order to better understand the particular applications for which different connectors are best suited, it is helpful to identify the classification of power connectors and their respective functional combinations. In general, power connectors are classified according to their live voltage. Power connectors fall into three categories: light, medium, and heavy, with each type referring to how much voltage the connector can withstand.

---------------------------------------------------------------------------------------------------

1. Lightweight power connector: Lightweight power connector can carry a small current of 250 volts (V). However, if the contact resistance does not keep the electrical frequency low and smooth, the ability of the component to carry current is likely to be compromised. In addition, minimizing the presence of extraneous contaminants at connector contact points such as dirt, dust, and water is critical, as components are susceptible to oxidation and contaminants can catalyze the reaction process. Power connectors used in automobiles, wireless communication and communication equipment, as well as power connectors used in instruments and equipment are lightweight power connectors. 2. Medium Power Connectors: Medium power connectors can carry higher frequency currents above 1000 V. Unlike low duty connectors, medium duty power connectors are highly susceptible to electrical damage if the contact material is not carefully managed to avoid inadvertent electrical welding and erosion. Therefore, the selection of appropriate raw materials is particularly important for the stability of machinery and equipment. Medium-sized power connectors can be found in a variety of home and industrial applications. 3. Heavy-duty power connector: Heavy-duty connector withstands high frequency current in the range of one hundred thousand KV (kV). Because of their ability to withstand large loads, heavy-duty connectors are reasonably effective for use in large-scale power distribution equipment and in battery management and maintenance systems such as circuit breakers. In addition to the three broad categories of power connectors above, there are many individual connectors that fall into each category. Some classifications include: AC connectors, DC connectors, wire connectors, blade connectors, plug and socket connectors, insulation piercing connectors. 4. AC connector: The key of AC power connector is the device connected to the wall socket to facilitate the power supply of machinery and equipment. The power cord plug in the AC connector is suitable for standard size equipment, and the industrial AC connector power cord plug is suitable for large industrial occasions. 5. DC connectors: Unlike AC connectors, DC connectors are not standardized. The DC power plug is a variant of the DC connector whose key is to power small electronic devices. Since the DC power plugs have different specifications, do not accidentally apply variants regarding compatibility issues. 6. Wire connectors: Wire connectors are used to connect two or more wires to a common connection point. Lug type, crimp type, set screw and split bolt type are all of this type. 7. Blade connector: The blade connector has a single wire connection blade connector, which is inserted into the blade power socket, and is connected when the wire of the blade connector and the wire of the receiver are in contact. 8. Plug and socket connectors: Plug and socket connectors are male and female, and they fit tightly with each other. Plug, a male part consisting of a number of prongs and pins which, when inserted into a socket, lock it firmly in the corresponding contacts. 9. Insulated piercing connectors: Insulated piercing connectors are effective because they do not require uncovered wires. Instead, a fully covered wire is inserted into the connector, and when it is in place, a small device in the opening clears the wire of the covering. The uncovered tip of the power line contacts the signal receiver and is able to transmit power.
