What Is a Pogo Pin Connector?

Pogo Pin Connectors are just like small springs that assist different electronic devices to connect each other effortlessly.  

They enable electronic devices to communicate smoothly and share information quickly and reliably without signal loss. Pogo Pin Connectors save space and provide high adaptability and durability.  

What Is The Structure Of A Pogo Pin Connector?  

A Pogo pin connector consists of three major components i.e. plunger, barrel, and spring. When a force is applied to a pin the spring can be compressed and the plunger can move into the barrel.  

• The plunger directly contacts a corresponding pad on the device. Its conductive nature and its being made up of brass and stainless steel ensures its electrical connection.  
• The Barrel of the connector provides structural support and space for the plunger house. It is made up of brass, plastic, or stainless steel.   
• The Spring provides the force required to push the plunger out and keep it connected with the corresponding pad. It is usually made up of beryllium copper or stainless steel.  

What Are the Design Considerations for Pogo Pin Connectors?  

When designing the pogo pin connector several key factors must be considered for excellent performance, longevity, and sustainability. Some of them are given below:  

Current Rating  

The current rating defines the amount of current that easily passes through the connector without damaging the electronic devices. Many devices can operate on varying power requirements, which require a current rating. If the current exceeds the limit it causes damage and overheating. And similarly, the current falling below the limit raptures the device.  

Contact force

A proper and stable electrical connection between the pogo pins and the mating surface is absolutely necessary. It helps minimize signal loss and electrical resistance. If the force exceeds a certain limit it can distort connector components and if it falls it breakdown signals.  

Mating cycle

A mating cycle is the number of times a connector is mated and unmated before distortion or failure. A high range of mating cycle connectors is appropriate for applications needing frequent connections and disconnections.   

How To Install The Pogo Pin Connectors?

Proper Pogo pin connectors’ installation is critical because they are purpose-specific. The procedure does not require any equipment. Follow the steps mentioned below for careful and efficient installation.

1. Positioning: Get started by cleaning the device on which this electrical device will be installed. Determine the exact position on a device to install them because proper positioning of pogo pin connectors is significant for perfect alignment.
2. Insertion: The insertion process involves the placement of pogo pins accurately into an electronic device in a secure way. Place it perfectly to align with the connecting surfaces.
3. Compression: After proper insertion, compress the pogo pin connector. By compressing it, it makes a connection with the electrical device.  
4. Testing: The testing step includes checking and functioning of Pogo pin connectors to avoid misalignment and guarantee smooth and versatile electrical connections.  

How Does Pogo Pin Connector Work?

The working principle of a pogo pin connector lies in its spring-loaded contact. It works on the connection between the plunger, barrel, and the spring. When pressure is exerted on the plunger, the spring inside the barrel works, and the plunger forms a temporary electrical connection, contacting the corresponding pad.  

The spring plays a vital role in the current flow and continuous connection force of the plunger with the target pad and in the mechanism of connection and disconnection. When pressure is removed, the spring pushes the plunger back into the barrel and disconnects the electrical connection. It supports frequent connection and disconnection cycles.

Note: Spring constant and material can be selected carefully to ensure the proper amount of force for smooth contact. It is necessary to prevent connector components and contact point damage. Hence, a suitable electrical connection decides the proper current. 

Types of pogo connector

Depending on their functions and needs in multiple electronic appliances, there are many types of pogo pin connectors. Some common types are given below as;

• SMT/SMD Pogo Pin Connector: Designed for surface mounting onto PCBs. They offer a low profile and are ideal for compact designs.
• Through Hole Pogo Pin Connector: Mounted through holes in PCBs. They provide secure connections and suit applications requiring a strong mechanical bond.
• Double-ended Pogo Pin Connector: Feature two plungers and one barrel. They can simultaneously connect with two contacts, increasing connection density.
• High Current Pogo Pin Connector: Handle higher electrical currents than standard Pogo pins. They are suitable for power applications and devices requiring larger currents.
• Right Angle Pogo Pin Connector: Mount horizontally onto PCBs at the right (90-degree) angle. They save space and offer flexibility in design layouts.
• Bending Type Pogo Pin Connector: Possess a flexible tail for bending and adapting to different angles and positions. They offer flexibility in tight spaces.
• Solder Cup Pogo Pin Connector: Have a solder cup termination for easy soldering onto PCBs. They provide a reliable and straightforward connection method.   

What are The Benefits and Drawbacks of the Pogo Pin Connector?

Advantages  

• Firstly, these connectors being very easy to handle/use are the best choice for electronic applications where frequent connection and disconnection are required. 
• One other benefit is their reliability in forming the electrical connection. It prevents signals and contact even in a vibration or moving environment.  
• Also, Pogo pin connectors are the best choice for applications with limited space because of their fantastic small sizes. 

Disadvantages

• Though they have high durability, the mating and un-mating cycle can cause them to break down with time. It causes failure of connectors which can be set by replacement or maintenance. 
• Another disadvantage of these connectors is the current rating. They are suitable for moderate current ranges and cannot be used for large-value current. For such applications, high-voltage connectors are utilized.
