Is spring-loaded pin or a pogo pin refers to a specific type of electrical connector mechanism. This mechanism is being used in many modern applications and electronic testing. Pogo pins are primarily used because they offer better durability than the other electrical contacts. They also provide increased resilience of connection towards vibration and mechanical shocks.
The name Pogo has been derived from the resemblance of the pin to a pogo stick. The helical spring, which is integrated into the pin, is responsible for applying a constant force against the back of the contact plate or mating receptacle. This is responsible for contracting any kind of unwanted movement which may lead to an intermittent connection. These helical springs make the pogo pins unique since all the other types of pins either use an expansion sleeve or cantilever spring.
The spring-loaded pins or pogo pins are precision parts that have been fabricated with a spinning or turning process that does not need a mold. Therefore, this allows for the production of smaller quantities at low costs.
Structure of a Pogo pin
A simple Pogo pin contains three main parts
- Plunger
- Barrel
- Spring
When a force is put on the pin, the spring undergoes compression. This leads the plunger to move into the barrel. The barrel has been designed in a way that it will retain the plunger. This stops the spring from pushing out the plunger if the pin is not locked.
Advantages of opting for a pogo pin
Pogo pins offer many advantages compared to all the other pins available in the market. That is why these pins have gained more popularity and are preferred.
Improvement in the user experience
Pogo pins are very easy to plug in. There is also no accidental drip off of the cable.
Stable current flow
Pogo pins are available in many designs. The different designs can be used to increase the current flow stability. This is done by increasing the number of contact points inside the pin.
Production of small volumes
Pogo pins are generally produced with the help of high-precision turning machines. They do not require a mold, as is the case with all the other connectors which are produced using the stamping process.
High current and limited space
The trend is leaning towards miniaturization. No other connector has shown a better space to current ratio. If you are planning to purchase pogo pins, check out the TTS group. This company has been helping its clients with test tooling solutions and semiconductor testing devices since 1979.
Simple assembly
Pogo pins reduce the manual labor time required for inserting cables and allow new design and arrangement options.
High tolerance
If there is even a minor error in the production, it will lead to unstable connectors. Pogo pins allow for a very high level of tolerance in production and decrease the likelihood of errors.
Long life
Pogo pins have been shown to have superior work duration compared to all other connector types.
