A POGO PIN or SPRING-LOADED CONNECTOR is a type of electrical connector mechanism that is used in many modern electronic applications and the electronics testing industry. They are used for their improved durability over other electrical contacts and the resilience of their electrical connection to mechanical shock and vibration.
The name POGO PIN comes from the pin’s resemblance to a pogo stick – the integrated helical spring in the pin applies a constant normal force against the back of the mating receptacle or contact plate, counteracting any unwanted movement which might otherwise cause an intermittent connection. This helical spring makes POGO PINS unique since most other types of pin mechanisms use a cantilever spring or expansion sleeve.
A complete connection path requires a mating receptacle for the pin to engage, which is termed a target or land. A POGO target consists of a flat or concave metal surface, which, unlike the pins, has no moving parts. Targets may be separate components in the complete connector assembly, or in the case of printed circuit boards, simply a plated area of the board.
POGO PIN CONNECTOR is precision parts fabricated with a turning and spinning process which does not require a mold, thus allowing the production of smaller quantities at a lower cost.
STRUCTURE
pogo pin structure
A basic POGO PIN (SPRING-LOADED CONNECTOR) consists of 3 main parts: Plunger, Barrel, and Spring. When force is applied to the pin, the spring is compressed and the plunger moves inside the barrel. The shape of the barrel retains the plunger, stopping the spring from pushing it out when the pin is not locked in place.
In the design of electrical contacts, a certain amount of friction is required to hold a connector in place and retain the contact finish. However, high friction is undesirable because it increases stress and wears on the contact springs and housings. Thus, a precise normal force, typically around 1 newton, is required to generate this friction. Since a POGO PINS needs to have a slight gap between the plunger and barrel so that it can slide easily, momentary disconnections can happen when there is vibration or movement. In order to counter this, the plunger usually has a small tilt to ensure a continuous connection
MATERIALS
The plunger and barrel of POGO PIN usually use Brass or Copper as a base material on which a thin layer of nickel is applied.
As common in electrical connectors, manufacturers often apply gold plating that improves durability and contact resistance.
As an indispensable opening feast for the electronics industry every year, Electronica China officially ushered in its 20th anniversary. It was successfully held in Shanghai International Expo Centre on April 14-16, 2021. The show attracted 1,116 exhibitors domestic and foreign, who presented their innovative solutions to 48,268 professional visitors on a total exhibition space of more than 60,000 square meters.
Zhenghe booth was located in C1. 2180, where have high technology connectors for car, military, lighting, consumer electronics, LOT, etc. Zhenghe exhibited multiple pin pogo pin connectors, magnetic pogo pin connectors, magnetic cable connectors, etc. We also brought out our new technology for pogo pin plating(Unique plating), and we received nice feedback from customers.
“Quality first, good reputation and quality service” is the tenet of our company. Zhenghe Precision is a reliable partner that you can trust, We will continue to work hard to provide customers with a better service experience.
Application of pogopin charging contacts on wireless earbuds
The smallest size is needed to attain powerful capabilities. The pogopin charging thimble contact utilized on the Bluetooth earphone demands an especially modest volume and must withstand a large present.
Waterproof and Anti-oxidation and rust: Many people do sports while listening to music. Human perspiration is corrosive. At this moment, the charging process of Bluetooth earphones has to be water-resisted to ensure the pogopin charging contacts aren’t Corrosion by individual perspiration won’t influence the usage of Bluetooth headsets.
Pogo Pin connectors are more convenient than other charging methods. We offer the best user experience.
Space Saving.
The right Connector for Small Space. Back drilling design is the best choice for a small size connector.
High Durability.
Pogo pins are vertically compressed which makes them extremely durable.
Simple Assembly Connection.
The pogo pin connector can automatically align with the device.
Stable Current Flow.
The resistance is small and stable, which can reduce the probability of instantaneous power failure.
