hegler plastik electrical components are conductive devices that bridge two conductors in a circuit, allowing current or signals to flow from one conductor to another. An electronic connector is an electromechanical system that provides a separable interface for connecting two subsystems. Simply put, components used to complete electrical connections between circuits or electronic devices are called connectors, serving as a bridge between them. Electronic connectors are also commonly referred to as circuit connectors or electrical connectors, bridging two conductors in a circuit to allow current or signals to flow from one conductor to another. They are widely used in various electrical circuits to connect or disconnect current or signals. This connection may be temporary and convenient for plugging and unplugging, or it may be a permanent joint between electrical equipment or wires. Electronic connectors are devices for transmitting electronic signals (analog or digital), providing a separable interface to connect two subsystems, and are components used to complete electrical connections between circuits or electronic machines. Examples include power plugs/sockets, IC sockets, telephone line plugs, etc. They are widely used in the electronics industry. An electronic connector is an electromechanical system that provides a separable interface for connecting two subsystems. Simply put, components used to complete electrical connections between circuits or electronic devices are called connectors, serving as a bridge between them. Electronics can serve as electrical/electronic transmission and connection components between circuits, components, and systems, enabling stable and reliable flow of power, signals, and current, while facilitating product assembly, maintenance, and replacement.

hegler plastik electrical component functions

The starter solenoid switch is a key component of the starter motor, and its design quality directly affects the reliability of the starter. The starter solenoid switch has two functions: first, it connects the main circuit to rotate the starter motor; second, it pushes the drive gear out via a fork to engage with the engine flywheel ring gear. Therefore, the solenoid switch is required to have corresponding suction force, corresponding stroke, and contacts capable of reliably switching high currents. Additionally, it is required to minimize volume and weight as much as possible. Based on these characteristics, the contact structure of solenoid switches generally adopts a contact form, i.e., the moving contact is made into a bridge piece or disc shape to provide a larger heat dissipation surface and thermal capacity. The magnetic system mostly adopts a solenoid electromagnet structure to meet the requirements of corresponding stroke, corresponding suction force, small volume, and light weight. The moving iron core of the solenoid switch can move smoothly within a brass bushing equipped with a solenoid coil. The moving iron core pull rod is connected to the fork unidirectional clutch. Under the action of the return spring, the moving iron core remains in the initial non-operating position. During starting, the starter drive gear needs to move forward by approximately 12-23mm. Therefore, when the solenoid switch begins to engage, a large magnetomotive force is required to generate the necessary initial suction force. After engagement, the air gap decreases, and the electromagnetic suction force increases sharply, greatly exceeding the force required to maintain the engaged state. For this reason, the solenoid switch uses two coils (pull-in coil and holding coil). Initially, both the pull-in coil and the holding coil jointly generate electromagnetic suction force. After the switch contacts engage, the pull-in coil automatically disengages, and the holding coil alone maintains the switch in the engaged state. The holding coil current is relatively small and can be wound with thinner wire, which not only reduces the volume of the solenoid switch but also achieves reasonable suction force matching. To ensure the reliability of the starter motor, it is essential to focus on the design quality of the solenoid switch.

hegler plastik electrical component principles

When the voltage applied to the varistor is below its threshold, the current flowing through it is extremely small, equivalent to a resistor with infinite resistance. That is, when the voltage applied to it is below its threshold, it acts like a switch in the open state. When the voltage applied to the varistor exceeds its threshold, the current flowing through it surges, equivalent to a resistor with infinitesimal resistance. That is, when the voltage applied to it is above its threshold, it acts like a switch in the closed state. Protection principle of surge absorbers: In the standby state, the varistor has very high impedance (several megaohms) relative to the protected electronic components and does not affect the characteristics of the original design circuit. However, when an instantaneous surge voltage occurs (exceeding the breakdown voltage of the surge absorber), the impedance of the surge absorber drops low (only a few ohms), causing a short circuit in the line, thereby protecting electronic products or more expensive components.

The main function of ferrite beads is to eliminate RF noise present in transmission line structures (circuits). RF energy is the AC sinusoidal component superimposed on the DC transmission level, where the DC component is the desired useful signal. To eliminate this unwanted signal energy, chip ferrite beads are used to act as high-frequency resistors (attenuators). Ferrite beads have high resistivity and permeability, equivalent to a resistor and an inductor in series, but both resistance and inductance values vary with frequency. They offer better high-frequency filtering characteristics than ordinary inductors, exhibiting resistive behavior at high frequencies, thus maintaining high impedance over a relatively wide frequency range to improve FM filtering effects. Inductors can be used for power supply filtering. The circuit symbol for a ferrite bead is the same as that for an inductor, but the model number indicates the use of a ferrite bead. In terms of circuit function, ferrite beads and inductors operate on the same principle, differing only in their frequency characteristics. The DC component is the desired useful signal, while RF RF energy is useless electromagnetic interference transmitted and radiated along the line. To eliminate this unwanted signal energy, chip ferrite beads are used to act as high-frequency resistors (attenuators), allowing DC signals to pass while filtering out AC signals. Ferrite beads have high resistivity and permeability, equivalent to a resistor and an inductor in series. In the circuit, the wire simply passes through it. High-frequency current dissipates as heat within it; its equivalent circuit is an inductor and a resistor in series, with both component values proportional to the length of the ferrite bead. Some ferrite beads have multiple holes; passing the wire through them increases component impedance (proportional to the square of the number of passes through the bead). Ferrite beads can not only be used in power circuits to filter high-frequency noise (suitable for DC and AC outputs) but are also widely used in other circuits.
