RYBASOELEKTRO electrical components are wires that transmit electric current. Typically, current transmission is point-to-point. Power cords can be classified by application into AC AC power cords and DC DC power cords. Usually, AC power cords carry higher-voltage alternating current; due to the higher voltage, these cables must comply with unified standards and obtain safety certification before formal production. In contrast, DC cables basically carry lower-voltage direct current, so their safety requirements are not as strict as those for AC cables. However, for safety reasons, countries still require unified safety certification.

RYBASOELEKTRO electrical component principle

Microphones have evolved from initial resistive electro-acoustic conversion to inductive and capacitive conversion. Many new microphone technologies have gradually developed, including aluminum ribbon and moving-coil microphones, as well as the currently widely used condenser and electret microphones. The working principle of a moving-coil microphone is that human voice causes the diaphragm to vibrate through the air, and then the electromagnetic coil winding on the diaphragm cuts the magnetic field formed by the magnet surrounding the moving-coil head, generating a weak fluctuating current. The current is transmitted to the amplifier, which converts the fluctuating current back into sound through the reverse process. For ribbon microphones, the aluminum ribbon serves as both the microphone diaphragm and the conductor moving in the magnetic field. The ribbon is usually made of aluminum foil. To achieve an ideal resonant frequency, the ribbon is corrugated to maintain a precise tension value. As a conductor and microphone diaphragm, the ribbon is suspended in the magnetic field between two magnetic poles, vibrating with the frequency of the incident sound wave, while generating a certain voltage output at both ends of the ribbon. A condenser microphone has two metal plates, one of which is coated with an electret film and grounded, and the other plate is connected to the gate of a field-effect transistor, with a diode connected between the gate and the source. The diaphragm of a condenser microphone is mostly made of perfluoroethylene propylene, which has good humidity performance, generates more surface charge, and is less affected by humidity. Since this transducer also has a capacitive structure with very high internal signal resistance, its output end must also use a field-effect transistor to extract and amplify the voltage signal generated by sound.

1, fuse resistor: also called a fusible resistor, it plays a dual role as a resistor and a fuse under normal conditions. When a circuit fault causes its power to exceed the rated power, it will blow like a fuse to disconnect the connected circuit. Fuse resistors generally have small resistance values and low power ratings. 8, sensitive resistor: refers to a resistor whose resistance value is sensitive to a certain physical quantity (such as temperature, humidity, light, voltage, mechanical force, and gas concentration). When these physical quantities change, the resistance value of the sensitive resistor changes accordingly, presenting different resistance values. According to sensitivity to different physical quantities, sensitive resistors can be divided into types such as thermistors, humidity-sensitive resistors, photoresistors, varistors, force-sensitive resistors, magnetoresistors, and gas-sensitive resistors. The materials used for sensitive resistors are almost all semiconductor materials, so these resistors are also called semiconductor resistors. The resistance value of a thermistor changes with temperature; if the resistance decreases as temperature rises, it is a negative temperature coefficient (NTC) thermistor. NTC thermistors are widely used and can be further divided into general-purpose NTC thermistors, voltage-stabilizing NTC thermistors, and temperature-measuring NTC thermistors. A photoresistor's resistance value changes with the intensity of incident light; when incident light increases, the resistance of the photoresistor decreases, and when incident light weakens, the resistance value increases.

Fiber optic connectors can be divided into common single-mode and multi-mode connectors for silica-based optical fibers according to the transmission medium, as well as other fiber optic connectors using plastic etc. as the transmission medium. According to the connector structure, they can be divided into: FC, SC, ST, LC, D15, DIN, MU, MT, and various other forms. Among them, ST connectors are usually used at the cabling equipment end, such as fiber patch panels and fiber modules; while SC and MT connectors are usually used at the network equipment end. According to the shape of the fiber end face, they are divided into FC, PC (including SPC or UPC), and APC; according to the number of fiber cores, there are single-core and multi-core (such as MT-RJ) distinctions. Fiber optic connectors are widely used and come in many varieties. In practical applications, we generally distinguish them according to the different structures of fiber optic connectors.
