What is Terminal Block(Compact Splicing Connector)

Wiring terminal is a kind of accessory product used to realize electrical connection, which is divided into the category of connector in industry. With the higher and higher degree of industrial automation and the more strict and accurate requirements of industrial control, the consumption of wiring terminals is gradually increasing. With the development of electronic industry, more and more terminals are used, and the types are more and more. In addition to PCB board terminals, hardware terminals, nut terminals, spring terminals, etc. are most widely used. The terminal blocks can be divided into European terminal block series, plug-in terminal block series, transformer terminal block, building terminal block, fence terminal block series, spring terminal block series, rail terminal block series, through wall terminal block series, optoelectric coupling terminal block series, 110 terminal block, 205 terminal block, 250 terminal block, 187 terminal block, od2.2 ring terminal block, 2.5 ring terminal block, 3.2 ring terminal block 4.2 ring terminal, 2 ring terminal, 6.4 ring terminal, 8.4 ring terminal, 11 ring terminal, 13 ring terminal flag series terminal and sheath series, various ring terminals, tubular terminals, wiring terminals, copper strip and iron strip (2-03, 4-03, 4-04, 6-03, 6-04), etc.

Attention of Compact Splicing Connector

  1. The tightening force of the wiring shall be moderate to prevent the bolts and nuts from slipping with excessive force. The bolts and nuts that have slipped shall be replaced in time. It is strictly prohibited to make do with the operation.
  2. When tightening or loosening the screws with a screwdriver, the screwdriver must be forced to hold the screws tightly, and then tighten or loosen them to prevent the screwdriver from slipping with the screws, causing damage to the screws and difficult to disassemble, especially the common air switch in the hanging box.
  3. If it is found that the bolts and nuts are difficult to disassemble, do not act rashly to prevent deformation and more difficult to disassemble. Knock them properly, or add screw loosening agent, dilute hydrochloric acid, etc. to disassemble later.
  4. Do not use a vice to tighten or loosen the bolts and nuts to prevent damage. When using a loose end wrench, adjust the opening to prevent damage and deformation of the bolts and nuts, resulting in difficult disassembly and assembly.
  5. At most two conductors of the same type and specification can be connected to the same wiring terminal.
  6. For the wiring terminals that are easy to loose or poor contact, the wire connectors must be marked with “?” Type A is fastened on the wiring terminal to increase the contact area and prevent loosening.
  7. When wire joints or wire noses are connected with each other, it is strictly prohibited to install non copper gaskets or gaskets with poor conductivity in the middle.
  8. When connecting the wire joint, the contact surface shall be smooth and free of oxidation. When the connection nose or copper bar is connected, the contact surface can be cleaned and coated with conductive paste before fastening.
  9. When connecting a temporary wire, the connector of a single conductor flexible wire shall be folded in half once, and then connected to the lower opening of the air switch; Single core hard wire shall be marked with “?” Type A is connected to the lower opening of air switch.
  10. For the wiring of 30kW and above motors, it is required that gaskets with poor conductivity, such as galvanized nuts, flat pads, spring pads, etc., are not allowed to be connected between the motor outgoing line and the cable conductor connecting the motor.
  11. When winding cables or other equipment to protect insulation with insulating tape, the insulating layer shall be wound from one end to the other end in the proportion of 1/2 of the pressure, and at least one round trip

Common Faults of Compact Splicing Connector

Significance of prevention

The plastic insulating materials and conductive parts of the terminal are directly related to the quality of the terminal, which determine the insulation and conductivity of the terminal respectively. The failure of any terminal block will lead to the failure of the whole system engineering. The bitter lessons learned at home and abroad in this regard are very profound.

Prevention is the purpose and analysis is the basis. In a sense, failure prevention is more important than failure analysis. It has more practical significance to ensure the quality and reliability of the terminal block.

From the perspective of use, the function of the wiring terminal should be: the place where the contact part is connected must be connected, and the contact is reliable. Where the insulation part should not be connected, it must be reliably insulated. There are three common forms of fatal failure of terminal blocks:

poor contact

The metal conductor inside the terminal is the core part of the terminal, which transmits the voltage, current or signal from the external wire or cable to the contact corresponding to its matching connector. Therefore, the contact must have excellent structure, stable and reliable contact retention and good conductivity. Due to unreasonable contact structure design, wrong material selection, unstable mold, out of tolerance machining size, rough surface, unreasonable surface treatment processes such as heat treatment and electroplating, improper assembly, poor storage and use environment and improper operation and use, poor contact will be caused at the contact part and mating part of the contact.

Poor insulation

The function of the insulator is to keep the contact parts in the correct position arrangement, and to insulate the contact parts and the contact parts and the shell from each other. Therefore, the insulating parts must have excellent electrical performance, mechanical performance and process molding performance. Especially with the wide use of high-density and miniaturized wiring terminals, the effective wall thickness of insulators becomes thinner and thinner. This puts forward stricter requirements for insulating materials, injection mold precision and molding process. Short circuit, electric leakage, breakdown and low insulation resistance will be caused due to the presence of metal residues, surface dust, welding flux and other pollution on the surface or inside of the insulator, the fusion of organic material precipitates and harmful gas adsorption film with the surface water film to form an ionic conductive channel, moisture absorption, mildew growth, aging of insulation materials and other reasons.
