What are Electronic Connectors?
Electronic connectors are components used in the joining of conductors to establish the completion of an electrical circuit.
Electronic connectors typically have a part that is inserted into another to form a connection.
These parts are colloquially referred to as male and female ends respectively.
Electronic connectors can be assembled permanently or temporarily.
When assembled temporarily, they can be removable as mating parts or need specific tools to help in their removal.
How is an Electronic Connector Constructed?
An electronic connector is a two-part construction constituting housing and connecting terminals.
The housing is an enclosure designed to hold the electrical terminals.
Additionally, it provides a rigid structure for the connection while protecting the electrical contacts from faults such as shorts.
You also find the housing useful in guarding against physical damage and other potentially destructive factors.
Hardened plastic material or sometimes ceramic is used to make the housing.
These materials are desired for their insulating property.
This way, they pose no harm to electrical shock to you as a user.
Rubber is sometimes added to the housing to protect it from mechanical/physical shock.
Terminals provide electrical connections to the connector allowing it to conduct electricity.
It consists of a configuration of pins that are made from a conductive material.
Such material can be metal or carbon.
What is an Adapter?
An adapter is a special type of electronic connector used to join disparate connectors.
Disparate connectors are connectors that are not physically compatible. These connectors, therefore, need.

- It should have limited instances of signal power loss that could arise when joining mating parts.
- A good connector should lose large amounts if not all, of the backflow signals to avoid interruption of input signals.
- The installation of a good connector should be simple enough or foolproof.
- Good connectors should be affordable.
- The reliability of electronic connectors should be dependable.
- A good electrical connector should not be adversely affected by its environmental conditions.
What are some Electronic Connector Types?
We have several types of electronic connectors. Some common connectors include.
1. Audio and Video Connectors
Audio and video connectors are electronic connectors used in the transfer of sound and video signals respectively.
The signal carried by this type of electronic connector can either be analog or digital.
An analog signal is continuous with time variations at different points of sampling.
A digital signal is discontinuously providing discrete values at different time intervals.
2. DC Connectors
This type of electronic connector is used in the distribution of direct current.
Most DC connectors are keyed to avert the dangers of wrong connection protocols.
There are many DC connectors such as the cylindrical connector used for powering mobile devices such as laptops.
This connector type is used in conjunction with an AC adapter.
Additionally, many vehicle fixtures are terminated with DC connectors for power distribution.
3. Dock Connector
Dock connectors are electronic connectors that carry multiple signals and power through a single connector.
These connectors are used to tether portable electronic devices to other external sources.
Dock connectors can be entrenched in a contraption or be the termination point of a cable.
You find dock connectors in use in portable electronic devices such as laptops and mobile phones.
In this case they find use as interface enablers to devices such as sound outputs and peripheral devices.
4. Edge Connectors
Edge connectors are a good example of the chip package to board or mounted connectors.
These connectors are usually part of the printed circuit board as male ends.
They provide slots for expanding the circuit board infrastructure through the addition of detachable cards.
The fringe cards used are usually receptacles forming the female end.
To ensure the use of only compatible cards, the edge connectors are keyed.
Some applications of edge connectors are personal computers and video game cartridges.
5. Coaxial Power Connector
Also known as barrel connectors, these connectors distribute external power to appliances requiring low voltage power inputs.
The male ends to coaxial connectors can be mounted on device panels or onto their printed circuit boards.
Coaxial power connectors come in different shapes and sizes.
Some plugs are interchangeable by the standardization of the receptacles.
They also feature locking properties and are characterized by a high retention loss.
6. Optical Fiber Connectors
Optical fiber connectors are employed at the terminations of fiber cables.
They are a better and a far more effective option for the use of line splices.
These connectors are useful in allowing simple connections of fiber cables both during manufacture and assembly.
This connector type is spring-loaded allowing a fit interface of the male and female connector parts.
Also, this ensures a continuous signal.
There are many types of optical fiber connectors with more advanced types accommodating increased ports for a single rack.
For fiber cables that are laid underground, the connectors are made airtight to protect the ends from underground moisture content and air.
How are Electronic Connectors Secured with the Wires?
Wire electrical connector
There are three methods with which conductors can be secured to the connector.
Common methods of affixing wires to electronic connectors include insulation displacement, crimping, and soldering.
· Insulation Displacement
Here, the wires are not bared to join them with the connector.
The connector has blades that form a tight grip over the wires.
This grip is just enough to cut through the insulation but not the wire.
The insulation displacement is time-saving but sometimes the blade could cut through the wire. Other times the blade could fail to get through the insulation.
You find this method of connection is less effective with a reduced ability to handle the current.
This kind of connection requires the use of a crimping tool to carry out.
The wires are placed in a crimping tool where they are uniformly stripped and joined to the connector.
Also, the connector is not permanently joined to the wires.
Crimping is user friendly and applicable for many electronic connectors with higher effectiveness.
When you solder electrical wires to connectors, you melt solder over the joint creating a connection.
The solder is usually a small metal wire that melts upon applying heat.
Soldering is more intensive than crimping and insulation displacement.
However, it is highly effective.
What is the Difference between Terminal and Connector?
A terminal is used to describe the endpoint of a conductor.
This point can either be fastened or connected to a connector.
When connected to a connector, connection to an external circuit can is possible.
As such, a connector can be a terminal when permanently fixed to the conductor.
What is the Pitch of an Electronic Connector?
The pitch of a connector describes the distance between pins on an electronic connector.
It is a physical parameter of an electronic connector and is measured in millimeters.
How do I Choose Electronic Connector?
You choose an electronic connector depending on your application needs.
The following are some elements to consider when choosing an electronic connector.
- The electronic connector’s parameter ratings: such as operating voltage, current, and temperature.
- The kind of termination needed for your connector. There are different terminations such as clamping, insulation displacement, and soldering.
- The space requirements demanded by the application, and the respective size of your desired connector.
- The nature of the environment. This informs on whether the electronic connector needs to have some custom abilities such as being waterproof.
What are Some of the Electronic Connector Features?
Different features are used to distinguish electronic connectors.
These features can be useful in certain specialized instances where they are required.
Some are described as follows:
· Keyed Connectors
These types of connectors are designed to be foolproof such that they cannot be wrongly joined.
Also, these connectors are aligned in such a way that joining them will be impossible in their misaligned state.
This kind of connector is useful in preventing the wrong connection that could be destructive to the electrical components being joined.
Additionally, they protect the pins from physical damage through attempted forceful insertion and circuits from the dangers of shorting.
· Locked Connectors
This feature of connectors locks the connecters once joined together.
Besides, this prevents the connectors from detaching at unintentional attempts such as pulling or jolting of the attached cables.
Locked connectors usually contained a mechanism for detaching the connector such as pressing down on the casing or a twisting mechanism.
· Specialized Connectors
Some connectors are required for use in certain special environments such as underwater and even space.
Such connectors require specialized design adjustments to mitigate the volatility of their environment. Some include:
· Water-resistant Connectors
These connectors can prevent the adverse effects of water on the connector parts.
When water gets into contact with electrical parts, it could cause shorting.
With these connectors, water is prevented from getting in contact with electrical contacts.
· Oil Resistant Connectors
These connectors are much like water-resistant connectors with the extra advantage of resisting adverse oil presence.
· Airtight Connectors
These connectors are useful for pressurized environments such as underwater.
Being hermetically sealed helps the connectors withstand external pressure that could affect the functioning of a connector.
What is a Pin Header?
Straight pin header
A pin header is a connector with either a single or multiple rows of pins.
Pin connectors are typically male and are internally employed in devices.
This connector type can be made such that it is straight or angular.
You find pin headers to be simple in design which allows their products to be less costly.
They are manufactured in strips with a high pin count that can be separated into smaller headers.
What is the Crimping Tool?
A crimping tool is a device used in joining together wires to a separate electronic connector.
Bare wires are arranged and placed into a crimping tool where they can be sliced to provide uniform termination.
To affix them to the connector, a force is applied to the connector wire assembly fastening the wires to the connector.
What is a Pinout in Electronic Connectors?
A pinout describes the pin layout on an electronic connector.
It provides the function or role of each pin.
The pinout is useful when you need to use a peripheral device such as an adapter.
What are Male and Female Connectors?
Male and female electrical connector
The nomenclature of male and female in electronic connectors refers to the two-part connectors involved in creating a connection.
Also, the male connector is inserted into a female connector to create a complete connection.
How is Strain Relief Useful to Electronic Connectors?
Strain relief is a protection mechanism fitted in the design of connectors to safeguard the cables from the strain.
The strain on the cables at the connection could result due to mechanical/physical shock.
For example, cables for input to output connectors can be tripped on or jolted with excessive force.
The result is an exertion of strain on the connection. Without the strain relief, the wires in the cables can sever.
What are the Specifications for Electronic Connectors?
There are many electronic connectors for use in different circuit applications.
Also, there are certain specifications attached to the connector itself and the applications that will be required for proper functionality.
These specifications can be categorized into physical and performance parameters.
Some performance parameters are described as follows.
· Current Rating
The amount of current a connector can conduct gives the connector’s current rating.
This is useful in helping you to determine whether the connector will function in your intended application.
Electronic connectors could be classified to support low current amounts, high current amounts, or medium currents.
The current rating is provided in amperes.
· Voltage Rating
The voltage rating provides the voltage amount sustainable by an electronic connector.
A connector could be designed high or low voltage depending on the voltage amount.
A measure of voltage is provided in volts.
· Working Temperature
The working temperature is a rating providing the optimum temperatures at which the electronic connector should ideally function.
It is often provided as a range highlighting the lowest temperature level and the highest temperature for proper connector functionality.
The parameters related to the electronic connector itself are referred to as physical parameters.
They include the following:
The pitch of an electronic connector describes the distance between the pin contacts.
It is provided in millimeters and differs from the pin configuration of a connector.
The pitch could be large or small and with it signify the size of the connector.
· Pin Contact Count
The number of pin contacts can be ascribed to the pitch.
You find that a smaller pitch highlights a large number of pins on a connector.
A large contact pitch provides a lower pin count on a connector.
· Construction Material
The housing and pins for electronic connectors are each made from insulating and conductive materials respectively.
For the housing, plastic or ceramic is preferred while sometimes rubber is used.
The connecting pins are made from metal or carbon compounds.
The material to be used in construction is however dependent on where the electronic connector will be applied.
Some applications will require a rigid casing with a high capacity to absorb physical shock.
Some contact pins will need to be highly conductive.
