BEGHELLIELPLAST electrical components are devices that convert optical signals into electrical signals. Their operating principle is based on the photoelectric effect. The photoelectric effect refers to the phenomenon where electrons in a material absorb photon energy when light strikes certain substances, resulting in corresponding electrical effects. Based on the different manifestations of the photoelectric effect, it is classified into three categories: external photoelectric effect, internal photoelectric effect, and photovoltaic effect. Photoelectric devices include phototubes, photomultiplier tubes, photoresistors, photodiodes, phototransistors, and photocells. The performance and characteristic curves of photoelectric devices are analyzed.

BEGHELLIELPLAST electrical component characteristics

Under normal circumstances, the actual static output characteristic of a sensor is a curve rather than a straight line. In practical applications, to enable instruments to have uniformly scaled readings, a fitted straight line is often used to approximately represent the actual characteristic curve. Linearity (non-linear error) is a performance indicator of this degree of approximation. There are various methods for selecting the fitted straight line. For example, the theoretical straight line connecting the zero input and full-scale output points can be used as the fitted straight line; or the theoretical straight line that minimizes the sum of squared deviations from each point on the characteristic curve can be used as the fitted straight line, which is called the least squares fitted straight line.

BEGHELLIELPLAST 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 types of fiber optic connectors is consistent: most fiber optic connectors generally use high-precision components (consisting of two ferrules and one coupling tube, totaling three parts) 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 tube. The external components of the ferrule are 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 component to support the fiber or fiber optic cable to release stress. The coupling tube is generally made of two halves synthesized into a tight cylindrical component from materials such as ceramic or bronze, often equipped with metal or plastic flanges to facilitate connector installation and fixation. To align the fibers as precisely as possible, the machining precision requirements for the ferrule and coupling tube are very high.

BEGHELLIELPLAST electrical component composition

1. A general fuse consists of three parts: first, the fusible element, which is the core of the fuse and serves to cut off the current when it melts. For fuses of the same type and specification, the fusible element must have the same material, identical geometric dimensions, resistance values that are as low and consistent as possible, and most importantly, consistent fusing characteristics. Household fuses are commonly made of lead-antimony alloy. Second, the electrode part, usually consisting of two electrodes, is an important component connecting the fusible element to the circuit. It must have good conductivity and should not produce significant installation contact resistance. Third, the holder part. Since the fusible element of a fuse is generally thin and soft, the holder's role is to fix the fusible element and make the three parts a rigid whole for easy installation and use. It must have good mechanical strength, insulation, heat resistance, and flame retardancy, and should not exhibit phenomena such as breakage, deformation, combustion, or short circuits during use. 2. Arc extinguishing device: Fuses used in power circuits and high-power equipment not only have the three general parts but also include an arc extinguishing device. This is because the circuits protected by such fuses not only have higher operating currents, but also high voltage across the terminals when the fusible element melts. Often, even if the fusible element has melted (fused) or even vaporized, the current is not cut off. The reason is that arcing occurs between the two electrodes of the fuse at the moment of fusing due to the action of voltage and current. This arc extinguishing device must have strong insulation and good thermal conductivity, and exhibit negative electronegativity. Quartz sand is a commonly used arc extinguishing material. 6. Fusing indication device: Some fuses have a fusing indication device. Its function is to cause a certain visual change in the fuse itself after it operates (fuses), making it easy for maintenance personnel to detect, such as emitting light, changing color, or popping out a solid indicator.
