Pogo pin belongs to a kind of precision electronic hardware material, is a thimble with compression elasticity, often used as current and signal transmission, that is, conduction and connection, factory as a connector.
Pogo pin is composed of three parts: needle shaft, spring and needle tube. Special applications will increase the insulation bead and other structures inside the Pogo pin
The internal structure of Pogo pin can be divided into: oblique profile, through hole pin shaft type, anti-drilling type, oblique profile with bead, oblique profile with retaining wall and retaining wall, bead needle type, etc. According to the different application scenarios of Pogo pin, that is, the performance parameters that need to be achieved such as high current, impedance, environment and other requirements to design different structures.
The external structure of Pogo pin is divided into: DIP, flat bottom, double head, welding line type, side post type, thread type, etc., and different structure installation methods are also different.
What if there were no Pogo pin connectors? In this case, continuous conductors should be used to permanently connect circuits. For example, if an electronic device is to be connected to a power supply, both ends of the connecting wire must be fixed to the electronic device and the power supply by some method (such as welding).
In this case, whether production or use, has brought a lot of inconvenience. For example, car batteries. If the battery cable is fixed and soldered to the battery, the car manufacturer will have to do more work to install the battery, adding production time and cost. When the battery is damaged and needs to be replaced, the car should be sent to the repair station to remove the old one and weld the new one again, which will cost more labor. With a connector you can save yourself a lot of trouble. Buy a new battery at the store, disconnect the connector, remove the old battery, put in a new battery, and reconnect the connector. This simple example illustrates the benefits of connectors. It makes the design and production process more convenient and flexible, reducing production and maintenance costs.
1. Pogo pin can better transmit the high-frequency signal of the antenna
Compared with other connectors, Pogo pin has smaller distributed capacitance and distributed inductance at the same working height due to shorter current path, especially in high frequency band, which is more conducive to impedance matching. Based on the same working height, Pogo pin in the self-resonant frequency band is much higher than the shrapnel, and the loss is smaller, which is conducive to the efficient transmission of high-frequency signals. Pogo pin in the metal frame design can be more flexible for signal transmission, so that the antenna radiation is further away from the motherboard and its components, more conducive to the play of antenna performance, at the same time, the contact and assembly scheme of Pogo pin is more flexible, in the metal battery cover, metal frame, ultra-thin model design has a better use of space, Therefore, Pogo pin has more advantages over other connectors in signal transmission.
2. Pogo pin can realize the connection scheme of large current
A Pogo pin is not just a gold-plated needle designed to withstand high currents; Its spring is also gold-plated at specific currents; In order to better carry the large current through to ensure the stability of the current, however, this is the antenna shrapnel can not do.
3, Pogo pin can be easier to achieve waterproof structure
4, Pogo pin can be accurate and stable connection point conducive to RF signal transmission
When Pogo pin connectors are used in antenna connectors, more stable connection points allow for more stable RF performance without frequency offset.
5. Pogo pin occupies smaller space and is more stable than other connectors
Compared with connectors of the same size, Pogo pin has greater compression and more stable contact. When it is strongly impacted by external force, the spring pressure of Pogo pin changes relatively little.
6. Pogo pin does not need to open stamping die, and the development, sample delivery and mass production time is short
7. Improve the production process
Connectors simplify the assembly process of electronic products. It also simplifies the mass production process;
8, easy maintenance
If an electronic component fails, it can be quickly replaced with a connector.
9. Easy to upgrade
Modern technology continues to update the metacomputer when the connector is installed, replacing the old metacomputer with a new, better metacomputer;
4. Improve the flexibility of design
Using the Pogo pin connector gives engineers greater flexibility in designing and integrating new products, as well as using components to build systems
