A pogo pin spring loaded pin is a type of electrical connector mechanism that is used in many modern electronic applications and in the electronics testing industry. A complete connection path requires a mating receptacle, called a target or land, that the pin engages. A target consists of a flat or concave metal surface that has no moving parts. It may be a plated area of a printed circuit board or a separate component in the connector assembly.
Barrel
A pogo pin spring loaded pin is a special connector that consists of 3 parts: a barrel, a plunger and a compression spring. This type of pin is commonly used for power supply connections and data communication connections in electronics. The name of the connector comes from its resemblance to a pogo stick and the spring mechanism that is integrated in the pin. This helical spring applies a constant normal force against the mating receptacle or contact plate and counteracts any movement which might cause an interruption of the connection.
The spring mechanism also provides an extra level of protection against wear and tear. While other types of connectors have two sheets of metal that scratch onto each other, the helical spring of a pogo pin eliminates this abrasion by compressing the whole connector assembly. This directional compression reduces wear and tear on each part and improves current carrying capacity.
Plunger
A pogo pin spring loaded pin is an electrical connector mechanism used in a variety of electronic applications and in the test industry. They are known for their durability and the resilience of their electrical connection to mechanical shock and vibration. The pin’s unique construction has an integrated helical spring that applies a constant normal force against the back of the mating receptacle or contact plate to counteract any unwanted movement that might otherwise cause an intermittent connection.
This design is also ideal for automatic test equipment where a dense array of connected pins facilitates rapid, reliable connection of devices under test (DUTs). The plungers are usually made of brass or copper and gold plated to improve their contact resistance. Plastic substitutes are a viable alternative for certain applications where steel may damage softer materials or leave unnecessary marks on the DUT.
Burn Resistor
Spring-loaded pins, also known as pogo pins, are an electrical connector mechanism that is used in many modern electronic applications. They are fabricated by a turning and spinning process without the need for a mold, which enables the production of smaller quantities at a lower cost. A pogo pin can be pressed between two electronic circuits to produce a connection. They are typically made use of in digital gadgets and circuits for a variety of objectives, such as connecting and also disconnecting components or establishing a quick and easy test factor.
A burn resistor was added to the mechanism to increase its holding capability and ensure that it performs a reliable release action in the in-orbit environment. This is because the conventional wire cutting release mechanisms can easily be damaged by solar panel vibration. This is a major concern for future CubeSat-based deployable solar panels, which must operate in a harsh space environment.
Nylon Cable
A pogo pin spring loaded pin is a type of electrical interface hardware that establishes a temporary connection between two circuits. This function can be useful for applications of separation devices, which require many mating and demating cycles. Moreover, pogo pins are characterized by their high working travel. This allows engineers to easily compensate for small production errors.
This is why they are used in some of the most demanding interconnect components. They can be found in portable equipment such as mobile phones/radios, barcode readers, medical, and test instruments. The slender cylinder of a pogo pin spring loaded pin can be compressed to form a secure electrical contact between two circuits by the restoring force. This function is very important for burn wire release-type HRMs that utilize the nylon cable cutting method for synchronously releasing multiple solar panels of a CubeSat.
Last Word
Spring loaded pins are a common type of fastener used in machine assembly. They are a tube-shaped pin with a split that expands and compresses upon insertion into the hole. There are several options to consider when choosing a spring-loaded pin or connector. These include base-area to length proportion, housing construction, tip geometry and material.
