Choosing the Right Electric Connectors with Gallon Electric

Electrical circuits are composed of a multitude of components, including wires and cables. Electrical connectors are used to join these to form a continuous path for electrical current to flow. Connectors have male-ends (plugs) and female-ends (jacks) which connect to each other forming either a permanent connection or, more often, a temporary connection that can be assembled and removed with special tools

Simply, an electrical connector is an electro-mechanical device for joining electrical circuits as an interface using a mechanical assembly. Connectors consist of plugs (male-ended) and jacks (female-ended). The connection may be temporary, as for portable equipment, require a tool for assembly and removal, or serve as a permanent electrical joint between two wires or devices. An adapter can be used to effectively bring together dissimilar connectors.

There are hundreds of types of electrical connectors. Connectors may join two lengths of flexible copper wire or cable, or connect a wire or cable to an electrical terminal.

In computing, an electrical connector can also be known as a physical interface (compare physical layer in the OSI model of networking). Cable glands, known as cable connectors in the US, connect wires to devices mechanically rather than electrically and are distinct from quick-disconnects performing the latter.

Electrical connectors facilitate the manufacture, assembly, and installation of electrical devices by cutting down labor, time, and effort. Electrical connectors are widely used in electronic devices, domestic appliances, telecommunication, industrial machinery, computers, and automobiles.

The market is flocking with hundreds of different types of electrical connectors and a couple of varieties to consider. The chances of getting the wrong electric connector for a specific task increases drastically. This is an indication that choosing an electric connector can be downright daunting.

Though, getting the right electric connector for the specific need is a reliable and efficient way of modulating and improving an electric system. That’s why Gallon Electric ensures that your electric system runs smoothly and reduces the chances of electrical repairs by providing reliable & high-quality connectors, terminals at the best price.

Properties of electrical connectors

Electrical connectors are characterized by their pinout and physical construction, size, contact resistance, insulation between pins, ruggedness, and resistance to vibration, resistance to entry of water or other contaminants, resistance to pressure, reliability, lifetime (number of connecting/disconnect operations before failure), and ease of connecting and disconnecting.


They may be keyed to prevent insertion in the wrong orientation, connecting the wrong pins to each other, and have locking mechanisms to ensure that they are fully inserted and cannot work loose or fall out. Some connectors are designed such that certain pins make contact before others when inserted, and break first on disconnection; this protects circuits typically in connectors that apply power, e.g., connecting safety ground first, and sequencing connections properly in hot swapping applications.

It is usually desirable for a connector to be easy to identify visually, rapid to assemble, require only simple tooling, and be inexpensive. In some cases, an equipment manufacturer might choose a connector specifically because it is not compatible with those from other sources, allowing control of what may be connected. No single connector has all the ideal properties; the proliferation of types is a reflection of differing requirements.

Things to consider when buying electric connectors

When you approach the market for electric connectors, it’s always advisable to make sure you are purchasing connectors that will solve your specific needs. For manufacturers, it’s advisable to maintain the quality and functionality of these kinds of electric components. This is to maintain your overall brand recognition and customer satisfaction. Here are some factors to consider before placing your order,

  • Specific requirements-Answer these two main questions when you are looking for electrical connectors. What numbers of signals are there? What currents, voltages, and frequencies or a combination is there? This is what will determine the connector type, wiring, and pinout. Make sure the needs of your customers are factored in before buying electric connectors wholesale.
  • Operating voltage and current rating-When selecting electric cable connectors, the current rating is a serious criterion to consider.
  • Space constraints-The size of the electric cable connectors has drastically reduced with the reduction in the space available. This is the same case with terminal connectors. For that reason, consider the space and make sure it matches the situation at hand.
  • The operating temperature range-The good thing is that most electric connectors are made to withstand extreme conditions including shock and vibration. The connectors manufactured to work in these extreme conditions have additional components that withstand the shock and extreme vibration.
  • Material and Plating-The the last factor to take care of is to consider the terminal materials and the plating. They are often underrated but this is very important.
