How does the environment affect the spring pin magnetic connector?
The influence of environment on spring thimble type magnetic connector
1, moisture resistance
Constant humidity and heat experiment conditions are at relative humidity 90%~95%, temperature +40±20℃. If the environment is too humid, the intrusion of moisture will affect the insulation performance of the connection H, and at the same time, it will rust the metal parts, thereby reducing the service life of the connector and changing its performance.
2, salt spray resistant
If it is necessary to operate in an environment full of moisture and salt for a long time, the metal structure of the pogo pin magnetic connector and the outer surface treatment layer of the contact is likely to undergo galvanic corrosion, which will affect the physical and physical properties of the magnetic connector. The electrical performance is affected.
3, temperature resistance
In practical application work, the maximum temperature rise allowed by the connector under the rated working current is clearly specified. If the temperature exceeds this specified temperature, it is absolutely not allowed, otherwise, it will have serious results on the product. Because when the connector is working, the current will generate heat at the contact point, resulting in a temperature rise, so the normal working temperature should be equal to the sum of the ambient temperature and the temperature rise of the contact.
It can be seen that the probe-type magnetic connector should pay attention to the influence of some external factors in the application process. Therefore, special attention must be paid to the maintenance of the magnetic connector during the application, so as to ensure the extension of its service life and the reduction of follow-up maintenance procedures.
The structure of the spring thimble is very simple, that is, the needle tube is hollow, the single-head PIN has a tail needle, and the general one has a flat bottom. The upper hole is filled with a spring and the needle is pressed into the needle tube. (Riveting), the needle can work normally without being pushed out by the spring; the bottom of the needle is divided into the flat bottom and inclined surface, the relative contact resistance of the inclined surface will be more stable, but if the inner wall of the needle tube is not processed well, The surface is rough, and the strength of the spring is small, which may cause problems such as card PIN
