【 Weak current College 】 connector categories and define 】

Due to the growing diversity of the structure of the connector, the new structure and application areas, attempting to use a fixed pattern to solve the problem of classification and naming, has become difficult to adapt. Nevertheless, some basic classification remains valid.
1. the level of interconnection
According to the electronic equipment and connectivity features, interconnect (interconnection) can be divided into five levels.

① chip packaging of internal connections

② I C package pins connection with PCB. Typical IC socket connector.

③ printed circuits and wires or printed circuit board connection. Typical connector for printed circuit connectors.

④ backplane and the backplane. Typical connector for Cabinet-type connector.

⑤ devices and equipment. Typical products of the circular connectors.

③ and ④ levels, have some overlap. In five levels of connectors, the market value is the highest and ⑤ ③ levels of product, which is currently the highest growth levels in the products section. ③
2. connector specification level.
In accordance with the International Electrotechnical Commission (IEC) classification, the connector is part of electromechanical components for use in electronic equipment, its specification levels are:

Categories (family): connector

Sub category (sub-family) example: circular connectors

Type (type): YB-circular connectors

Varieties (style) example: YB3470

Specifications (variant)
3. definition of the connector in China.
In our industry, the connectors and switches, keyboards, etc., collectively referred to as electronic components, electrical plugs Connector components and electrical components are collectively referred to as relays.
4. connectors product categories.
Connector products division although some confusion, but from a technical point of view, the connector product category has only two basic partitioning approach: ① press shape structure: circle and rectangular (cross section), ② press working frequency: low frequency and high frequency (bounded by 3MHz).

In accordance with the above Division, coaxial connectors are round, printed circuit connectors belongs to the rectangle (historically, printed circuit connectors is separated from the rectangular connector from a class), but currently popular rectangular connector of the section is the trapezoid, approximate the rectangle. Bounded by 3MHz divided low frequency and high frequency and radio frequency allocation is basically the same.

As for any other purpose, installation, special structures, special performance, etc. can also be divided into a number of different types, and often appear in publications and manufacturer's publicity materials, but generally just to highlight some basic characteristics and uses, within the above categories still divide principles.

Considering the connector technology development and actual situation, from its versatility and associated technical standards, the connector can be divided into the following categories (sub category): ① ② low frequency circular connector, rectangular connector; ③ printed circuit connectors; ④ RF connector; ⑤ fiber optic connectors.
5. type designation for the connector. Connector designation is customer acquisition and organization of production on the basis of the manufacturer. In the domestic and foreign connector industry, the product model name, there are two approaches: one letter code plus a number of ways, to reflect the designation of the main structural features of the product. The benefits of this approach is easily recognizable, but arrange for too long, too complex, along with the miniaturization of the connector, to print a lot of difficulties. At present, still popular in this way, and in some of the industry standard even makes provision in the national standard, such as SJ2298-83 (printed circuit connectors), SJ2297-83 (rectangular connectors), SJ2459-84 (ribbon cable connector), GB9538-88 (ribbon cable connectors). Due to the growing diversity of the structure of the connector, in the practice of using a naming convention covering a certain type of connector is becoming more and more difficult. Another way is to use a combination of numerals. The benefits of this approach is simple, easy-to-computer management and small product logo print. International main connector manufacturers are adopting this approach. You can expect from the manufacturer to develop to reflect their own unique naming approach will gradually replace the planned economy uniform provisions by the entire industry a naming rule.
