IMT36179 electrical components are parts that connect the battery to external conductors. In electrical engineering, terminals mostly refer to wiring ends, also called terminal blocks. Types include single-hole, double-hole, socket, hook, etc. By material, they are classified as silver-plated copper, galvanized copper, copper, aluminum, iron, etc. Their main function is to transmit electrical signals or conduct electricity. In engineering, it is the interface reserved by pre-station works for post-station works, and is the embedded facility for post-station interface works. When observing objects with a terminal cross-section inspection microscope, it can produce an upright three-dimensional spatial image with strong stereoscopic effect, clear and wide imaging, and has a long working distance; equipped with a high-precision wire harness terminal image measurement and analysis system, combined into a wire harness terminal inspection microscope, the perfect combination of high-quality optical systems and high-resolution cameras makes cross-sectional images clearer, and unique fixed magnification levels make measurements more accurate. To detect whether the terminal crimping is good, professional testing equipment is required. Common terminal testing equipment includes: terminal cross-section analyzer

IMT36179 electrical component principle

Microphones have evolved from initial resistance-based electro-acoustic conversion to inductive and capacitive conversion. Many new microphone technologies have gradually developed, including aluminum ribbon moving-coil microphones, as well as the currently widely used condenser microphones 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 loudspeaker, 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 resonance 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 the two pole faces, 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 (FET), with a diode connected between the gate and the source. The diaphragm of a condenser microphone is mostly made of fluorinated ethylene propylene (FEP), which has good humidity performance, generates more surface charge, and is less affected by humidity. Since this transducer is also of 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.

IMT36179 electrical component principle

A fuel cell is an energy conversion device that converts the chemical energy stored in fuel and oxidant directly into electrical energy isothermally according to electrochemical principles, i.e., the working principle of a primary battery, so the actual process is an oxidation-reduction reaction. A fuel cell mainly consists of four parts: anode, cathode, electrolyte, and external circuit. Fuel gas and oxidizing gas are introduced into the anode and cathode of the fuel cell, respectively. The fuel gas releases electrons at the anode, and the electrons are conducted to the cathode through the external circuit and combine with the oxidizing gas to form ions. Under the action of the electric field, the ions migrate through the electrolyte to the anode, react with the fuel gas, form a loop, and generate current. At the same time, due to the electrochemical reaction itself and the internal resistance of the battery, the fuel cell also generates a certain amount of heat. In addition to conducting electrons, the cathode and anode of the battery also serve as catalysts for the oxidation-reduction reaction. When the fuel is a hydrocarbon, the anode requires higher catalytic activity. The cathode and anode are usually porous structures to facilitate the introduction of reaction gases and the discharge of products. The electrolyte serves to transmit ions and separate fuel gas from oxidizing gas. To prevent the mixing of the two gases from causing internal short circuits in the battery, the electrolyte is usually a dense structure. The composition of a fuel cell is the same as that of a general battery. Its single cell consists of positive and negative electrodes (the negative electrode is the fuel electrode and the positive electrode is the oxidant electrode) and an electrolyte. The difference is that the active substances of a general battery are stored inside the battery, thus limiting the battery capacity. However, the positive and negative electrodes of a fuel cell do not contain active substances themselves; they are just catalytic conversion elements. Therefore, a fuel cell is truly an energy conversion machine that converts chemical energy into electrical energy. When the battery is working, fuel and oxidant are supplied externally for reaction. In principle, as long as reactants are continuously input and reaction products are continuously removed, the fuel cell can generate electricity continuously.

IMT36179 electrical component structure

What everyone uses is the unidirectional thyristor, also known as the ordinary thyristor. It is composed of four layers of semiconductor materials, has three PN junctions, and has three external electrodes: the electrode drawn from the first layer of P-type semiconductor is called the anode A, the electrode drawn from the third layer of P-type semiconductor is called the control gate G, and the electrode drawn from the fourth layer of N-type semiconductor is called the cathode K. From the circuit symbol of the thyristor, it can be seen that, like a diode, it is a unidirectional conductive device, but with an additional control gate G, which gives it completely different operating characteristics from a diode. The P1N1P2N2 four-layer three-terminal device based on silicon monocrystal is internationally known as the silicon crystal thyristor, abbreviated as thyristor T, because its characteristics are similar to those of a vacuum thyratron. Also, because thyristors were initially used in static rectification, they are also called silicon controlled rectifiers, abbreviated as SCR SCR. In terms of performance, SCR not only has unidirectional conductivity, but also has controllability more valuable than silicon rectifier elements (commonly known as "dead silicon"). It has only two states: conduction and off. SCR can control high-power electromechanical equipment with milliampere-level current. If this power is exceeded, the switching loss of the component increases significantly, and the allowable average current decreases accordingly; in this case, the nominal current should be derated. SCR has many advantages, such as: controlling high power with low power, with a power amplification factor of up to hundreds of thousands of times; extremely fast response, turning on and off within microseconds; contactless operation, no sparks, no noise; high efficiency, low cost, etc. Weaknesses of SCR: poor static and dynamic overload capability; easily susceptible to interference and mis-triggering. SCRs are mainly classified by appearance into: bolt type, flat plate type, and flat bottom type. Structure of SCR components. Regardless of the shape of the SCR, their cores are composed of four layers of P1N1P2N2 structure made of P-type silicon and N-type silicon. It has three PN junctions (J1, J2, J3). The anode A is drawn from the P1 layer of the J1 structure, the cathode K is drawn from the N2 layer, and the control gate G is drawn from the P10 layer, so it is a four-layer three-terminal semiconductor device.
