7 Features of Using Pogo Pin
Connectors loaded with pogo pins (also known as Pogo Pin Connectors) are gradually becoming popular and used in products by major well-known manufacturers. For example Apple, and Microsoft.
About the origin of Pogo Pin
As the 7 reasons mentioned in the title, the following briefly explains the origin of the pogo pin. Connectors have been generally used for more than 50 years. Engineers with more seniority did not recommend pogo pins at first. They believed that the use of pogo pins was unstable, low current, sensitive to any vibration, and not suitable for other data transmission equipment.
Since the semiconductor test industry has boomed in recent years, the performance of spring-loaded test pins has improved significantly. In response to technological development, product size is required to be minimized. To meet connector specifications, semiconductor process test pins are applied to pogo pin connectors. The pogo pin made by the middle probe is almost less than 2mm, and less than 0.1mm is rare.
Wondering why pogo pin connectors are so popular these days?
Why is it applicable to many applications? let me tell you!
1. Comparatively lower cost
Most connectors use a stamping process, in which the metal sheet is made into the appropriate shape using modules. Click this video to learn about the process!
In contrast, pogo pins use a turning process to quickly turn the metal stock without additional scraping of the ends. The difference between the two processes is the cost of manufacturing the modules. Modules can cost up to $5,000, and these are of course included in the cost and are one of the factors that affect the price of the product. The cost is calculated as follows:
Connector price + module cost/quantity = final price per unit connector
0.4USD+3500USD/10.000=0.75USD
Especially for a small number of connectors that need to be customized, spring-loaded connectors are the most efficient alternative. In the illustrated example, the spread can increase by up to 80%.
2. Improve the user experience
Spring-loaded connectors are very convenient, and in Apple's products, we're pretty sure that's the case. When I first used the Apple tablet's magnetic charger, I was quite confused. As long as it is close to the notebook, the charger will be directly attached to the computer, which is very convenient to use and is a clever design.
Once these products are improved a little, they can create impressive results for consumers and attract more brand loyal customers. Pogo pins enhance the customer experience, in particular, using automated and consistent usage.
3. More suitable for use in small size
Most connectors are stable but relatively bulky, otherwise, they are small but easily damaged. However, the spring-type connector combines the above two advantages, and the size is extremely small, but it can withstand 1,000,000 times of use. When the coil spring is evenly compressed, the spring increases the pressure at the bend. Due to the special internal spring design, it can maintain a small The advantages of size and stability.
4. The option with the longest service life
Connectors that carry pogo pins are extremely durable. Unlike other connectors, when the pogo pins are pressed vertically, all components can reduce a certain amount of wear on each component during the pressing process. The problem is that when the connector is inserted, there will be scratches on both sides, which will destroy the surface coating, reduce the current carrying capacity, and will seriously affect the greater force required to use the plug-in connector. However, when the components of the pogo pin rub, without cross affecting the needle shaft and the needle tube, the engineer will limit and specify the friction force generated internally.
5. High tolerance tolerance
The pogo pin connector provides a higher travel space than the internal structure of the general connector and gives engineers and users a high degree of freedom when using the connector, and the manufacturing error will not cause too many problems. For example, in the case of LG's G6 smartphone partnership, there was a problem with a malfunctioning fingerprint sensor on the back of the phone. When the user touches the fingerprint sensor, the small flat spring connector inside the mobile phone will feed back to the mobile phone system. In warm areas, the plastic back shell will expand to separate the junction from the connector. Use pogo pins to avoid connection Excessive stroke produced by the device during use, resulting in damage.
6. Easy to assemble
The way engineers assemble is the main consideration in the design. It takes extra processes and expensive costs to manufacture general connectors while using pogo pins for board-to-board connections requires no special finishing.
In the assembly process with high flexibility, components can be assembled quickly, which is why pogo pins are the best choice. We also provide pogo pins with a screw function, which enables engineers to combine the functions of installation and connection.
7. Provide steady current
Finally, the pogo pin provides an unimaginably stable current and can be independently assembled with special spring force and design. When the elastic force is increased, the extrusion of the needle shaft inside the needle tube will be more stable and have better electrical conductivity.
The design of the high-current pogo pin can make the current more stable. If a momentary interruption occurs, the flow of current through the spring will burn the spring and eventually cause the needle to fail. Therefore, by increasing the number of contact points between the needle shaft and the needle tube, the chance of instantaneous interruption is reduced.
