Connection Function Of Terminals And Insulators
2022-12-05
Electrical Connection's insulators not only function as insulation, but also provide accurate neutralization protection for extended contacts, and have the functions of installation, positioning, locking and fixing on equipment. Terminal Block is an accessory product used to realize electrical connection, which is industrially divided into the category of connectors. Terminal Block With the increasing degree of industrial automation and stricter and more precise industrial control requirements, the amount of terminal blocks is gradually increasing. With the development of the electronics industry, the use of terminal blocks is increasing, and there are more and more types. The terminal block is used to facilitate the connection of wires. It is actually a piece of metal sealed in insulating plastic. There are holes at both ends for inserting wires, and there are screws for fastening or loosening. For example, two wires, sometimes If they need to be connected, sometimes they need to be disconnected. At this time, they can be connected with terminals, and they can be disconnected at any time without having to weld them or twist them together, which is very convenient and quick. If it is not fixed, a slight collision will cause an instantaneous power failure of the contact reliability, and the serious one is the disassembly of the product. Disintegration refers to the abnormal separation between the plug and the socket, between the pin and the socket caused by the unreliable structure of the terminal due to the material, design, process and other reasons in the mated state, which will cause the power transmission of the control system and Serious consequences of interruption of signal control. Due to unreliable system design, incorrect selection of terminal materials, improper selection of molding technology, poor quality of heat treatment, mold, assembly, welding and other processes, improper assembly, etc. will affect the fixed assets of the enterprise. In addition, the appearance may be poor due to plating peeling, corrosion, bruising, molded case flashing, cracking, rough contact processing, terminal deformation, etc. Due to market positioning, locking fit dimensions are out of tolerance, and the quality of processed products is consistent. Poor performance, excessive total separation force and other reasons are also common bad interchange behaviors, which can generally be found and eliminated in a process of inspection and use in a timely manner. After the terminals have been used for a period of time, the insulation of some terminals will drop. In order to do a good job of prevention, we should first check the raw materials, because the quality of the raw materials should have a great influence on the insulation performance of the insulator. Don't blindly reduce costs and lose the material quality of materials. You should choose materials from large factories with good reputation, and carefully check important information such as batch numbers and material certifications for each batch of materials, and make traceability data for the use of materials. Next, check the insulation resistance of the Electrical Connection terminal insulator. In some production workshops, after the finished products are assembled according to the technical regulations, the electrical performance test is performed. As a result, the insulation resistance of the insulator itself is unqualified, resulting in the scrapping of the entire batch of finished products. A reasonable process should be 100% process screened in the state of insulator parts to ensure that the electrical performance is qualified.
