Take you to know the common problems of terminal blocks and the types of terminal blocks with high-definition pictures
Terminal block is an important accessory product used to realize electrical connection, from system, sub-system, cabinet, etc. It is responsible for the power transmission and signal control and transmission of the control system, which determines the ubiquitous application of terminals. As long as wiring is required, wiring terminals are required.
With the increasingly frequent use of terminal products in the field of wiring, the structure and wiring method of the terminal have undergone great changes. From a single branch terminal to a multi-level branch terminal, the wiring speed has also been greatly improved, reducing the need for users. At the same time, the reliability of the terminal is getting higher and higher. Due to the importance of the terminal, the design, production and use of the terminal must comply with relevant standards such as safety and environmental protection. Only when the standard is met, can it be used with confidence , in order to avoid the hidden dangers of safety accidents,
1. How to wire the terminals
To use the terminal block, the materials that need to be prepared include: screwdriver, terminal block, and wire.
1. First, strip 6-8 mm of the insulation of the wire.
2. Then insert the exposed wire into the inside of the terminal.
3. Then use a screwdriver to tighten the screws on the top.
Fourth, pull it by hand to ensure that it will not fall.
5. Then press the switch and see that the light is on, so the wiring of the terminal is completed.
2. Terminal FAQ
A. The problem of poor contact
The metal conductor inside the terminal is the core part of the terminal, and the current or signal is transmitted to the corresponding contact of the matching connector. Due to the unreasonable structural design of the contact parts, unstable molds, excessive processing dimensions, rough surfaces, unreasonable surface treatment processes such as heat treatment and electroplating, improper assembly, harsh storage and use environments, and improper operation and use, the contact parts and coordination of the contact parts will be damaged. The parts cause poor contact.
B. The problem of poor insulation
The function of the insulator is to keep the contacts in the correct position. Therefore, the insulator must have excellent electrical properties, mechanical properties and process forming properties. There is excess metal on the surface or inside of the insulator, surface dust, flux and other contamination are damp, and organic materials are precipitated. The adsorption film of substances and harmful gases fuses with the surface water film to form an ionic conductive channel, moisture absorption, mold growth, aging of insulating materials, etc., will cause short circuit, leakage, breakdown, low insulation resistance and other poor insulation phenomena.
C. Fixed bad issues
Poor fixation, lightly affecting reliable contact and causing instant power failure, serious product disintegration, due to unreliable design, wrong material selection, improper selection of molding process, poor quality of heat treatment, mold, assembly, welding and other processes, assembly is not in place, etc. Poor fixation.
The above are the pictures of various types of high-end boutique terminals that are commonly used, and you can buy them according to your needs.
