I want to eliminate poor contact at the charging connector of a smartphone.
Do you ever experience poor contact at the connector part of your smartphone or tablet after using it for a certain period of time, making it impossible to charge or otherwise work properly?
In such cases, there is a product that can help.
Problem Solution
The "Contact Cleaning & Resurrection Convenience Set" eliminates poor contact at once!
Metal contact points such as the charging connectors of smartphones and tablets are covered with various contaminants such as grease, carbon, and oxide film.
This is often the cause of poor contact.
In such cases, the "Contact Cleaning & Resurrection Convenience Set" is useful. It can solve problems such as poor contact in one shot.
How to use "Contact Cleaning & Restoration Convenience Set
-
Remove dirt with "Contact Cleaner". Wipe off the dirt with a special cotton swab if necessary.
-
Apply a small amount of "Contact Resurrection King".
- The included special cotton swab (industrial cotton swab) is suitable for cleaning precision equipment because it does not produce cotton dust.
Other uses
In addition to smartphone charging connectors, the product is also effective for the following applications
- Resolving poor contact with SD cards, USB cables, retro games, etc.
- Earphone and headphone jack maintenance, noise (galling) removal, and sound quality improvement
- Since there are many possible causes of malfunctions in electronic equipment, the use of this product may not always eliminate the problem.
Trivia
Sanhayato developed and commercialized "Contact Resurrection Agent.
Contact point resister" is now a common name, but it was first invented and commercialized in Japan by Hayato Sangyo (now San Hayato Co., Ltd.) in 1962.
(It is currently marketed as "Contact Resurrection King" with improvements.)
We hope you will try this proven product, which has been used for many years in the electronics industry in Japan, at home as well.
What is happening at the contact point? ~Principle of energizing this product
Generally, the surface of metal is uneven when magnified, and electrical contacts such as connectors are energized only at "points" on the convex part of the metal, resulting in an unstable state where contact resistance is not constant and many of the electrical signals that should be transmitted are missing.
When this solution is applied to electrical contacts, a very thin oil film of several nanometers is formed in the recesses. Electrical signals flow through this very thin oil film due to a phenomenon called the tunneling effect. This increases the area of current-carrying area, which reduces contact resistance and stabilizes the state of current-carrying.
