What is the difference between the mass interconnection interface and the traditional connection scheme? After reading it, you will understand Tengfang Zhongke TFC
When it comes to massive interconnection interfaces, many people do not know them. First of all, let me introduce to you: What is a mass interconnection interface?
As the name suggests, Massive Interconnect Interface =Massive (signal)+Interconnect InterfaceIn summary, it is an interface platform that can transmit massive signals. It is mainly used in large-scale test systems for signal combing.
● So what is the difference between it and the traditional connection scheme?
1. The number of channels for transmitting signals is different
1) There are two common connection schemes: one is the direct connection of cables, which can connect up to 200 signal points at a time; One is the cable junction box configuration, where a junction box connects up to 100 signal points at a time
2) Massive interconnection: Because it is a large-scale universal interface platform, the scalability is very high. At present, Tengfang's CMV-50 (also called V50) series of products can connect more than 9600 signal points.
2. Different types of transmitted signals
1) Ordinary connection scheme: single signal, cannot be mixed
2) Massive interconnection scheme: a variety of signal types are mixed, such as ordinary electrical signals, power, radio frequency, optical fiber, pneumatic and other signal types
3. The scalability of the connection scheme is different.
1) Traditional connection scheme: the connection scheme can only be confirmed at the time of initial wiring, and it is difficult to change the following after confirmation.
2) Massive interconnection scheme: The product adopts a modular combination form, and the required signal points can be added at any time in the later stage according to the requirements, and the combination of multiple connection schemes can also be realized by replacing ITA
4. Later maintenance methods are different
1) Traditional connection scheme: all are connected by wire, which is very troublesome for later maintenance and difficult to disassemble and assemble.
2) Mass interconnection scheme: provide hinge installation/direct installation/slide rail installation and other installation forms, and cooperate with the matrix module with digital marks to quickly maintain the equipment
5. Different plug life
1) Traditional connection scheme: Due to cable stress and connector limitations, it can accept up to 1000 times of plugging and unplugging
2) Massive interconnection scheme: the product adopts modular and labor-saving lever structure handle, with a maximum labor saving of 80 times and can accept 20000 times of plugging and unplugging.
6. Cabinet cleanliness is different
1) Traditional connection scheme: cables are arranged in disorder and cabinets are in disorder.
2) Massive interconnection scheme: modular universal connection scheme, which can perfectly fit with the cabinet, clean and tidy
7. Stress is different
1) Traditional connection scheme: If the cable is bent in a narrow space, the bending radius is limited, and the stress generated is also very large, which will damage the PXI and the rear connector.
2) Massive interconnection scheme: the self-contained stress relief board and the design of the module slot reduce the stress damage of the interface. At the same time, the service life of the test instrument is also increased because the interface of the test instrument does not need to be plugged and unplugged frequently.
● A massive interconnected system like this is currently mainly used in multi-species and small-batch testing.
There are not many companies that can do this kind of massive interconnection system. International brands include:
1)VPC: Established in 1959, it focuses on mass interconnection, measurement and control connection schemes and has been deeply engaged in the measurement and control connection industry for more than 60 years, involving military industry, aviation, aerospace, semiconductor, energy, automotive electronics and other industries.
2)MACPANEL: Established in 1958, with the development of the enterprise, it is currently more focused on PCB-connected mass interconnection systems, and the industries involved are basically the same as VPC.
In the Chinese market, VPC occupies the absolute market of the industry.
Long-term market monopoly, and everyone's anxiety about domestic brands, so that many domestic brands have not been outstanding performance.
under the influence of sino-us trade friction,The process of localization began to accelerateMore and more hardcore domestic brands come into view, and the quality and price also make everyone call their conscience.
LikeTengfang Zhongke, a Chinese company focusing on interconnection system solutions, has also begun to enter the public eye, and since its establishment in 2019, it has gradually launched its own research and development and production.
1) Rack panel series: suitable for measurement and control cabinets, from 2 module slots to 50 module slots, with a maximum connection of 9600 signal channels.
At the same time, in order to meet the customer's demand for space, the V25 series also introduced a lower vertical height of the cabinet.
2) Handheld connector: used for the secondary transfer of rack panel series or as the standard interface of portable case, providing the choice of 160~960 signal channels.
3) Automatic connector: High-density connector for fully automatic test assembly line, providing 160~640 signal channels.
In the electrical performance part, it is also in line with international big names. All products provide test reports. In some electrical properties, such as time delay and contact resistance, the performance is more prominent. The key is that Tengfang Zhongke controls the whole process from the various molds of the product to the final product and has its own production workshop and technical team. This also makes the product relatively more advantageous in price.
