Terminals are important components of system engineering. From systems, sub-systems, cabinets, combinations, printed boards to each replaceable independent unit, thousands of terminal blocks are distributed in various systems and systems like a human nervous system. The part is responsible for the power transmission and signal control and transmission of the control system. So this determines the application of the terminal is ubiquitous, as long as there is a terminal where wiring is required.
Implementation standards of terminal blocks:
Due to the importance of terminal blocks, the design and use of terminal blocks must meet the relevant standards of safety and environmental protection. Only when the standards are met, can you buy with confidence and use peace of mind to avoid the hidden dangers of safety accidents. General terminal blocks The manufacturer implements GB/T 5095-1997 electromechanical components for electronic equipment (basic test procedures and measurement methods) when designing finalized products: UL486E, UL1059.
Innovation of terminal products in its field:
With the increasing use of terminal products in the field of wiring, more and more users have put forward more requirements on them. For this reason, the structure and wiring methods of the terminals have undergone great changes. From the original single structure change, a variety of wiring structures have been extended, which are divided into categories and suitable for various wiring environments, which greatly facilitates our use. At the same time, the structure of the connection terminal is becoming more and more humanized, and the connection speed is also greatly improved, which reduces the labor intensity of the workers. At the same time, the reliability of the terminal blocks is getting higher and higher. The use of new production processes and technical equipment, scientific production processes and quality control methods have greatly improved the quality and life of the terminal blocks. With the increasing demand for environmental protection, the environmental protection requirements of the terminal are very necessary. Halogen-free addition of flame retardants, non-toxicity of conductor insulators, and lead-free plating of coatings are all positive responses to this request.
Material nylon (PA66), flame retardant grade V0, at the same time does not contain any harmful halogen, superior flame retardant performance, safety and environmental protection. Other commonly used materials are thermoplastic polyester (PBT); and used in conjunction with perforated reflow technology Liquid Crystal Polymer (LCP)
The printed circuit board terminal with screw connection has always occupied an important position in the electronics industry, and has now become an important component of the printed circuit board. Its structured design takes into account the characteristics of convenient wiring and reliable screw connection.
Spring connection terminal:
The printed circuit board terminals of the spring connection mode are divided into two types: pull-back spring connection and butterfly spring connection. Among them, the pull-back spring terminal and the screw terminal are compatible with each other, which greatly increases the flexibility. Reliable connection: front connection, obvious connection, low maintenance, no need to tighten.
IDC free stripping fast wiring terminal:
IDC stripping-free fast wiring terminals can realize fast connection of insulated wires without using any tools. Pull the opening aid lever to push the wire into the knife edge and cut off the insulation to achieve air-tight connection. This wiring method saves up to 60% of wiring time, no need to strip, no tools, only need to disconnect, nothing more. Moreover, it can be used for Ethernet wiring (Category 5) through certification.
Regardless of the connection method of the terminal blocks, they all have the following advantages:
1. Large wiring capacity, which can adapt to various wiring requirements.
2. The wire clamping frame and the soldering pin are mechanically decoupled, that is, because the wire clamping frame and the soldering pin are not connected as one body, the torque when tightening the screw will not be transmitted to the solder joint.
3. The welding pin has a quadrangular prismatic shape, and the end shrinks and becomes thinner. When inserting the solder hole, the contact area is increased. Welding liquid is easy to dissolve into the welding hole, and it is not easy to weld.
4. The solder pins are made of copper alloy, and the solder pins are free of dirt to ensure the long-term reliability of welding.
5. Tinned solder pins, easy to solder.
6. With heat dissipation channel.
7. The end of the soldering pin shrinks and becomes thinner, making it easy to install.
