The development of hardware abrasives has an important impact on the manufacture of high-end molds for terminals. The quality of terminals depends on the terminal material and the mold used to produce the terminals. As long as the production cost is sufficient, the material selection can be controlled, but the selection of the mold custom access door for the terminal is a major problem. At present, my country's high-end terminal products mostly rely on imports, and are mostly controlled by brands such as Phoenix and WAGO in the world. Although there are terminal manufacturers such as Lianjie, Youle, and Supu in China, their scale is far less than the former.

The reason is nothing more than the difference in molds. The cost of good molds is too high for enterprises to bear. For the domestic terminal mold market, hardware abrasives play a key role. For the current development of my country's hardware mold abrasive industry, there are many problems. At present, the country lacks effective industry norms for the mold industry, the entry requirements are low, and the market standardization is poor. Luo Baihui, secretary general of the Inteational Mold Association, pointed out that the main mold products in the development trend of the domestic hardware industry mold industry should be larger, more precise, more complex and more economical and fast, but at present, there are many main problems facing the development of my country's hardware mold abrasive industry:

1 ,. The research and development strength is weak, and the innovation achievements are few. The weak R&D strength is related to the small scale of the industry and the small number of scientific researchers, but more importantly, business leaders need to have a sense of collaborative innovation, and business leaders also need to strengthen leaing and innovative concepts in order to achieve innovative results. Second, the problem of overcapacity is prominent. The current production capacity of brown corundum is about 4.3 million tons, and the capacity utilization rate is less than 30%. According to the information of the branch, there are still about 250,000 tons of production capacity under construction and expansion, which will further exacerbate the production of excess capacity.

The production capacity of green silicon carbide is about 2 million tons, and the capacity utilization rate is about 15%. There are still a lot of outdated production capacities. Enterprises are slow in adjusting product structure and eliminating outdated production capacity. The homogeneity of products is serious. Under the circumstance that electricity prices, labor costs, and raw material costs continue to increase, enterprises can only use lower prices to spread low costs, which is also an important reason why prices have not gone up.

3. There are still outstanding problems in clean production, especially in smelting. The discharge of waste water, waste gas, dust and other pollutants in the abrasive processing process lacks control. Abrasives are likened to the teeth of industry", which play an indispensable role in railway construction. With the further advancement of my country's railway construction, grinding machines and equipment for railway processing, as well as powerful grinding wheels for rail dressing, are facing huge development space. The development of the hardware mold abrasive industry can not only improve the image and brand of its own enterprise, but also can be applied to many domestic industries. Terminal mold is one of them.

Spring terminal is a kind of connector composed of insulating components and hardware. It is named because the fixed metal is a spring; springs are usually divided into two types in the field of  Terminal Blocks Suppliers terminals: in-line springs and cage springs. The in-line spring is more precisely a kind of shrapnel, and the wire can be inserted directly without any auxiliary tools, as shown in the figure below; the cage spring needs a screwdriver to assist the wiring. Both types of spring devices have the advantages of convenient wiring, stability, anti-vibration and maintenance-free.

From the perspective of connector market growth share, the demand has increased significantly in recent years, and the entire type is in an upward trend. In recent years, the country's industrial manufacturing, automobile industry, electrical and electronic industries and other industries have flourished, and the connector industry, as one of the basic parts and components, needs to have an early stage of development in order to adapt to the country's entire industry. rapid development.

Spring terminal connectors are trusted in many fields because of their convenience and stability. Therefore, the expansion of the scale and variety of spring connector products and the improvement of the quality level are also the needs of the replacement of electrical equipment and the need to improve the performance of the supporting host. It plays an important role in the electrical industry, manufacturing and other fields. Spring terminals can be divided into four types according to their functions: plug-in spring, rail spring, plug-in rail spring, and panel mounting.

According to the market demand, the R&D center of the company keeps innovating to create a variety of spring-type terminal blocks: Plug-in springs: LC6/LC60, LC8/LC80 from 2.54mm to 5.08mm, the diversity of pitches has long ago provided a variety of possibilities for the installation environment ; The unique wall-penetrating matching technology brings great convenience to the partition installation. Rail spring: WST/MST/STL/LDK rail terminal has always been a popular product for large control cabinets.

It has a large number of digits and high wiring density. Although single-piece splicing is troublesome to install, some terminals can be replaced at any time if there is a problem. If the long terminal is a frame-type crimping screw, it will waste a lot of time, manpower and material resources, while the advantages of the spring terminal are obvious, the wire can be compressed when the screwdriver is pressed, and the anti-vibration performance is strong, it is a good choice. In order to avoid the energy consumption of chip assembly, Lianjie launched the LD series of integrated spring terminals, which integrates splicing and integration, leaving the initiative to engineers.

Plug-in rail: LC25/LC26 rail plug-in is a new type of wiring. If high-density rail wiring is not required, the rail plug-in terminal made of PA66 is an advantageous choice. Most of the traditional rail plug-in terminals are frame-type crimping terminals. In order to meet the needs of customers, Lianjie has created the LC25/LC26 series of spring rail plug-in terminals, which integrate convenience and high quality, and further enhance the product diversity. Ordinary spring: LS/LSC LS/LSC series is the earliest spring terminal, which already occupies a place in the market. The products also provide customers with a variety of choices in terms of spacing, performance, and materials. Shanghai Lianjie Electric has been deeply involved in the terminal market for 20 years. It has gradually transitioned from sales to a complete business process integrating production, leaing and research. It has accumulated a lot of experience in the connector industry, and continues to develop and innovate to provide customers at home and abroad with a better connection experience.

  With the development of the times, the iterative upgrade of electrical and electrical products is accelerated, and the connector installation environment is also changing. In order to better meet the needs of through-wall connection and improve the efficiency of connector installation, Lianjie has launched a new LZ5-LC6-LC60 series of spring through-wall terminals. combination. Two pitches of 3.81/5.08mm are provided, and the disc-type shrapnel is used for fastening, which makes the connection faster and the operation more convenient. Compared with the traditional box-type crimping method, the operation efficiency can be improved by 10 times.

In the daily electrical installation and use environment, the power supply outside the box often needs to be connected to the equipment in the box. In order to realize the signal connection, the through-wall terminal emerges as the times require.

The through-the-wall function avoids the redundancy caused by wrapping wires and is simple and straightforward. The three-in-one through-wall combination terminal is small and delicate, and the operation is safe, fast, and more convenient. The mating terminal adopts the in-line disc spring connection technology for fast and safe connection of single-stranded conductors and multi-strand conductors with ferrules. On the one hand, the spring connection technology has firm wiring, strong air tightness between conductive parts and wires, and is not easy to be corroded, which can avoid signal loss caused by excessive resistance; on the other hand, the wiring is fast, and the wire can be directly inserted to complete the installation, maintenance-free , Free inspection. Some people may have conces about the  terminal block in china   connection method of spring wiring.

The elasticity is reduced, what should I do if I can't press it tightly? The attenuation of elasticity is mainly affected by two aspects: the magnitude of the force and the material change. The shrapnel is made of stainless steel and electroplated with pure tin, which has strong oxidation resistance and low probability of material degeneration; that is, as long as the spring is within a reasonable force range, the spring will not experience elastic attenuation, or the probability of attenuation is very small. It shows that the spring connection method can be used with confidence, and the market practice also proves the effectiveness of the spring connection. Different devices and different installation environments require different number of terminals.
