If we use the 3.5 headphone socket when the contact is bad, how to deal with the specific details we will give you a detailed introduction below.
3.5 Earphone socket manufacturers analyze the causes of poor contact and Countermeasures
3.5 Earphone socket manufacturers, metal contact, if there is a significant external force, contact conditions change, we are more easily understood. For example, when the connector contacts badly, it may be good to press it by hand. Some devices have poor internal contact, vibration or knock on the device, sometimes it may be good, then knock, and may be poor contact.
However, there are some bad contact phenomena, which seem strange on the surface.
The problems of pressure, deformation, oxidation and impurities on the surface of the metal will affect the contact of the metal parts. The actual situation of "good contact" between metals that the naked eye thinks is far less perfect than people imagine! Secondly, there is another problem that bothers us. Why does contact have good jet lag?
At the same time, 3.5 headphone socket manufacturers said that the impact of impurities can not be ignored. When metal surface contacts with other substances, it will be contaminated with impurities. For example, on the skin of a person's hand, in fact, there are a lot of sweat grease and other substances. When a person touches a pin or terminal, they will stick these impurities to its surface. In addition, the air contains a lot of dust, which includes dust, dust, particles produced by friction between various substances, tail gas, smoke, man-made fiber dust, salt mist, body debris and foaming, microorganisms, and so on. Metals exposed to air are bound to be contaminated with these particles. These impurities are invisible to the naked eye, so the pins or terminals of these components may be considered "clean".
Little wonder, these impurities are a "giant" for atoms. Impurity cage covers the metal surface, which affects the direct contact between the metal atoms of the two devices, thus further reducing the actual effective contact surface.
On the other hand, 3.5 headphone socket manufacturers introduced that metal surface oxidation and impurities, will also lead to poor contact. We say that the pins or terminals are not oxidized, which is seen with the naked eye. In fact, metals exposed to air are bound to be oxidized to varying degrees, which are closely related to metal materials, environmental conditions and storage time. Gold-plated coatings are considered to be less easily oxidized. In fact, gold is not completely non-oxidized, but relatively less oxidized. Other coatings are easily oxidized.
Therefore, in general, the naked eye judges that "no oxidation" is only that oxidation is not very severe, in fact, oxidation is an objective existence. Metal oxides are non-conductive. Therefore, some oxide layers have been distributed on the surface of these pins or terminals, which further reduces the actual effective contact surface.
