EMILE MAURIN electrical components refer to electronic components that can open a circuit, interrupt current flow, or direct it to other circuits. The most common switches are manually operated electromechanical devices with one or more electrical contacts. "Closed" contacts indicate conduction, allowing current to flow; "open" switches indicate non-conduction, forming an open circuit and preventing current flow. The simplest switch consists of two metal pieces called "contacts"; when they touch, current forms a loop, and when they do not, the circuit is open. When selecting contact metals, consider their corrosion resistance, as most metals form insulating oxides after oxidation, preventing normal contact operation. Selection also requires considering electrical conductivity, hardness, mechanical strength, cost, and toxicity. Contacts are sometimes plated with corrosion-resistant metals, typically on the contact surface, to avoid performance degradation due to oxides. Non-metallic conductive materials, such as conductive plastics, are sometimes used for contact surfaces. In addition to contacts, switches have moving parts that make or break contact. Switches are classified by moving part type, such as lever switches, push-button switches, and rocker switches, while moving parts can also be other types of mechanical linkages.

EMILE MAURIN electrical component structure

The main purpose of fiber optic connectors is to achieve fiber splicing. Fiber optic connectors, widely used in fiber optic communication systems, come in many types with varying structures. However, upon closer examination, the basic structure of various fiber optic connector types is consistent: most generally use high-precision components (consisting of two ferrules and one coupling sleeve, three parts in total) to achieve aligned fiber connections. This method involves inserting and fixing the fiber into the ferrule, polishing the ferrule surface, and achieving alignment within the coupling sleeve. The ferrule's outer component is made of metal or non-metallic materials. The mating end of the ferrule must be polished, while the other end typically uses a strain relief boot to support the fiber or fiber optic cable and release stress. The coupling sleeve is generally a tight cylindrical component made of two halves synthesized from ceramics or bronze, often equipped with metal or plastic flanges for easy connector installation and fixation. To align fibers as precisely as possible, high machining precision is required for both the ferrule and the coupling sleeve.

EMILE MAURIN electrical component principles

The basic principle of a multimeter uses a sensitive moving-coil DC ammeter (microammeter) as the meter head. When a small current passes through the meter head, it indicates current. However, since the meter head cannot handle large currents, resistors must be connected in parallel and series to shunt or drop voltage, thereby measuring current, voltage, and resistance in the circuit. The measurement process of a digital multimeter converts the measured quantity into a DC voltage signal via a conversion circuit, then converts the analog voltage into a digital value using an analog-to-digital (A/D) converter. An electronic counter then counts this value, and the result is displayed directly as numbers on the screen. Voltage, current, and resistance measurement functions are achieved through the conversion circuit; current and resistance measurements are based on voltage measurement, meaning digital multimeters are expanded from digital DC voltmeters. The digital DC voltmeter's A/D converter transforms continuously changing analog voltage over time into digital values, which are counted by an electronic counter to obtain the measurement result, then displayed by a decoding display circuit. Logic control circuits coordinate circuit operation, completing the entire measurement process sequentially under clock control.
