FEINMETALL Pogo Connectors
Battery and charging contacts are often also called pogo connectors or simply short travel probes due to their compactness and their short travel.
They are particularly suitable as charging contacts and as interfaces for data transmission. But Pogo Connectors are also used in many end products where low-wear electrical contacts are required. Wherever quick-release electrical connections are needed, pogo connectors can be a clever solution. From charging rechargeable batteries, to applications in medical technology, all the way to use in the furniture and lighting industry.
Pogo connectors have to meet a wide range of requirements. These are, for example, compact design, short travel, long mechanical lifetime, solderability, high-temperature resistance, transmission of high currents, low contact resistance, good signal transmission in case of vibrations and, of course, a moderate price. Pogo Connectors can be mounted directly or as block units.
The spring can guide the plunger with the largest possible diameter. The plunger ends are slightly tapered to avoid scratching the probe housing (barrel).
The drilled plunger creates additional space for the spring and allows shorter pogo pin designs or higher spring forces.
Due to the angle at the end of the plunger, the spring creates a deliberate lateral force and thus ensures better contact between plunger and barrel.
Due to the angle at the end of the plunger, the spring creates a deliberate lateral force and thus ensures better contact between the plunger and the barrel. The ball inside stabilises the spring for better performance, but requires additional space.
The two angled plunger segments create a secure contact pressure towards the barrel which leads to a low contact resistance. The plunger moves parallel to the axis and does not deflect.
