Today, industrial systems contain a vast array of electrical components and equipment, ranging from PCBs, sensors, drives, motors, industrial computers, electrical cabinets, and even production lines, machines, and more. , they usually need to be connected to each other and work together. In this process, various types of industrial connectors actually play a very important role, such as: carrying power, transmitting control signals, connecting data communication between devices... It can be said that there is no industrial connector, Things like IoT, smart manufacturing...etc are all for nothing.
Don't underestimate industrial connectors. Although not large, the technology involved is not simple. On the one hand, the reliability of the electrical connection directly determines the performance of the equipment system; on the other hand, in the face of different types of application scenarios, the classification of industrial connectors is extremely complex. In fact, this brings some difficulties to our day-to-day product development and system integration.
First, start with the definition and classification of connectors, and talk to you about the basic rules for naming connector product models.
Any electrical system must use electrical current as a carrier of signal or energy, passed from one conductor to another by contact between conductors. This way of contact between conductors is called electrical contact, and it is the connector that completes this electrical contact task, covering the three lifelines of power, signal and data.
To put it figuratively, a connector is a "bridge" that carries current or signal connections. Although it is only one component, it plays a vital role.
So far, there is no unified classification standard for connectors, new application fields are constantly emerging, and the structure is increasingly diverse. It is difficult to classify and name connectors with a fixed pattern. Nonetheless, some basic classification principles still hold. Next, let's first understand the prerequisites for connector classification.
1. According to the internal and external connection function of electronic equipment, the interconnection level is divided into 6 layers:
Layer 1: Component-to-package interconnection;
The 2 layer: the interconnection between the package and the circuit board;
The 3 layer: board-to-board interconnection;
Layer 4: Interconnection between components;
Layer 5: Interconnection of components to input and output interfaces
2. Classification by structure:
3. According to appearance classification:
Circular connectors, mostly used in military equipment;
Rectangular connectors are widely used and develop rapidly.
Now, the module connector has become a dazzling "star" in the connector family.
The optical fiber connector;
Contactless connectors (eg proximity switches).
The classification of connector products has been introduced above, you can remember. If users want to know more about connector products, they need to know the name of their product model, that is, the order number.
The product model name is the basis for user procurement and connector manufacturers to organize production. Throughout the connector industry, it follows two principles:
One is the way of adding letters and numbers in an attempt to reflect all or the main structural features of the product in the model name. The advantage is that it is easy to identify; the disadvantage is that the model may be longer and more complex; with the development trend of connector miniaturization, the space that can be printed is getting smaller and smaller, and the printing of the code is more and more difficult.
The second is the combination of pure Arabic numerals, which is simple, easy to manage, and easy to print.
It is foreseeable that these two ways will coexist for a long time and continue to enrich and develop.
