Power connector Since the size of the power source ranges from small batteries to large power grids, connectors that allow power transmission vary. Depending on the current carried and the purpose of the application, one of several types of power connectors may be suitable. In order to better understand which connector is best for a particular purpose, it is helpful to check the classification of power connectors and the function of each variant.

Generally, power connectors are classified according to the voltage they carry. There are three types of electrical connectors: light, medium and heavy. Each category heading refers to how much voltage the connector can handle.

Lightweight power connectors can carry low currents up to 250 volts (V). However, if the contact resistance cannot be kept low and stable, it may impair the device's ability to transmit current. In addition, it is very important to minimize the presence of external contaminants on the connector contacts (such as dirt, dust and water), because components are prone to oxidation and contaminants can catalyze the process. Power connectors in automobiles, radio and communication equipment, and power connectors for basic instruments are all classified as lightweight power connectors.

The medium power connector can carry higher level currents up to 1,000V. Unlike low-load connectors, if the contact material is not carefully monitored to prevent inadvertent welding and corrosion, medium-sized transformers may suffer electrical wear. Therefore, proper material selection is essential to ensure the integrity of the equipment. Mid-size can be found in a range of domestic and industrial applications.

Heavy-duty connectors can carry high-level currents of hundreds of kilovolts (kV). Because they can carry large loads, heavy-duty connectors are effective in large-scale power distribution applications as well as power management and protection systems (such as circuit breakers).

Various types of power connectors

In addition to the three main categories of power connectors, there are many individual connectors belonging to each title. Some of these variations include:

AC connector

The AC power connector is mainly used to connect the device to a wall outlet to power the device. Among the types of AC connectors, power plugs are used for standard size devices, while industrial AC power plugs are used for larger industrial applications.

DC connector

Unlike AC connectors, DC connectors are not standardized. The DC plug is a variant of the DC connector that mainly powers smaller electronic devices. Since there are different standards for DC plugs, it is important not to accidentally use incompatible variants.

Wire connector

The purpose of a wire connector is to connect two or more wires together at a common connection point. Lugs, crimping, fixing screws and split bolt types are all examples of this variant.

Blade connector

The blade connector has a single wire connection-the blade connector is inserted into the blade socket, and the connection is made when the wire of the blade connector comes into contact with the wire of the receiver.

Plug and socket connectors

The plug and socket connectors are composed of male and female components, which fit closely together. A plug, a male part, consists of many pins and pins. When inserted into a socket, the plug is firmly locked on the corresponding contact.

Insulation piercing connector

Insulation piercing connectors are useful because they do not require uncovered wires. Instead, insert the fully covered wire into the connector, and when the wire is slid into place, the small device in the opening removes the covering of the wire. Then, the uncovered tip of the wire comes into contact with the receiver and can transmit electricity.
