Description

Novel high life electric capacity guide pin

Technical Field

The utility model relates to an electric capacity guide pin technical field specifically is a novel high life electric capacity guide pin.

Background

Two conductors close to each other with a layer of non-conductive insulating medium in between constitute the capacitor. When a voltage is applied across the two plates of the capacitor, the capacitor stores charge. The capacitance of the capacitor is numerically equal to the ratio of the amount of charge on one conductive plate to the voltage between the two plates. The basic unit of capacitance of a capacitor is farad (F). The capacitor element is generally denoted by letter C in the circuit diagram. Capacitors play an important role in circuits such as tuning, bypassing, coupling, filtering, etc. The tuning circuit of the transistor radio is used, and the coupling circuit, the bypass circuit and the like of the color television are also used. With the change of electronic information technology, the update speed of digital electronic products is faster and faster, and the production and sales volume of consumer electronic products such as flat panel televisions (LCDs and PDPs), notebook computers, and digital cameras is continuously increasing, which drives the growth of capacitor industry.

In a direct current circuit, a capacitor is equivalent to an open circuit. A capacitor is a component capable of storing electric charges and is one of the most commonly used electronic components. This is to be said from the structural point of view of the capacitor. The simplest capacitor is made up of two end plates and an insulating dielectric (including air) in between. When energized, the plates become charged, creating a voltage (potential difference), but the entire capacitor is non-conductive due to the intervening insulating material. However, such a case is under the precondition that the critical voltage (breakdown voltage) of the capacitor is not exceeded. It is known that any substance is relatively insulating, and that substances are conductive when the voltage across them increases to some extent, which voltage is called the breakdown voltage. The capacitor is no exception, and after the capacitor is broken down, the capacitor is not an insulator. However, in the middle school stage, such voltages are not seen in the circuit, so that the circuit works below the breakdown voltage and can be regarded as an insulator. However, in an ac circuit, the direction of the current changes as a function of time. The capacitor is charged and discharged with time, in which a varying electric field is formed between the plates, which is also a function of time. In practice, current is passed between the capacitors in the form of an electric field.

The conventional capacitive guide pin greatly shortens the service life of the capacitive guide pin due to the problem of heat dissipation, thereby affecting the service life of equipment, and therefore an improved technology is urgently needed to solve the problem existing in the prior art.
