Electrical connectors are used to protect from mechanical or physical damage, extreme weather conditions, and electrical interference. Just like any other item, before you buy an electrical connector, you may be interested in knowing more about it. For instance, if you hear of an FSC 5935 Electrical Connectors where does one start to understand more about it. Here then are a few bits of general information on electrical connectors.
Perhaps the first bit of information is that electrical connectors have a specific definition. For the sake of international manufacturing and shipping standards, electrical connectors have a specific definition that separates them from other electrical components. That is why under each electrical connector is a precise product definition. The US Census Bureau assigned electrical connectors number 8548900100 under the Trade Control Compliance for items that can be exported overseas.
Electrical connectors have unique part numbers
The Part Number (MPN) of an electrical connector uniquely identifies the connector and separates it from the others. Connectors also have MFG numbers, NIIN and other numbers that make it easy to identify the connector. These numbers are very important because each number identifies a distinct connector. For example, the Federal Supply Class (FSC) code for plugs, electronic component sockets, jacks, receptacles, and their accessories is 5935. After this number comes other numbers that are specific to a certain electrical connector. Let’s take an example. The connector with NSN number 5935-00-001-1627 is a Backshell electrical connector whose MGF number is 73-811203-27. It is very easy to look for this connector as long as you know its part numbers well.
Different types of electrical connectors
Electrical connectors come in different types. There are backshell electrical connectors, for instance. There are also cover electrical connectors which are slightly different from backshell connectors. The best way to identify different types of electrical connectors is to check the part numbers carefully. With these numbers, you will be able to place each connector in its right category. You will also be able to distinguish an electrical connector from an amplifier and other closely related electrical components.
Electrical connectors come in various specifications
As you would expect, electrical connectors come in different specifications. Precisely, different electrical connectors have different cable opening diameters. They also have different nominal thread sizes, thread classes and thread quantities per inch. The thread direction can either be right hand or left hand. Thread series designator also varies from one electrical connector to the other. Other features that differ from one connector to the other include cable opening quantity, furnished items, mounting facility type and quantity, overall height and overall width. You need to check each of these features to make sure that you get the exact electrical connector that you are looking for.
Electrical connectors are mainly made of aluminum
Aluminum is a good conductor of both heat and electricity, and this explains why electrical connectors are mainly made of aluminum. Other parts may be made of different materials, but the major parts of the connector are made of aluminum. For example, most of the electrical connector seals are made of rubber. The surface treatment may also be of a different material like cadmium.
