First, when plugging and unplugging, hold down the head instead of pulling the wire out. This is a habit of many people, because the recognition of the degree of importance of the terminal connection wire is not enough, so when plugging and unplugging, the wire is pulled directly, resulting in internal fracture and reducing its service life. At the same time, folding or bending the cable near the plug will also reduce its service life.
Second, do not place the terminal connection wires in dusty and humid places. This will easily lead to oxidation of the terminal connecting wires, resulting in poor contact.
Third, improper connection can easily damage the terminal connection wire harness. It is understood that when 40% of people find that there is a problem with the terminal connection wire harness, they will randomly find a tape wrap, but do not know how to smooth the connection, which will cause a short circuit or open circuit, and naturally it will not work properly.
