Profile Connectors Engineering Has A Wide Range Of Applications

The reason for applying the Profile Connectors in the primary place is that the mating interface is separable. There are many reasons for the need for separability. It can make part or sub-system independently and the final assembly can be carried out in a major place. Detachability also allows maintenance or upgrades of parts or subsystems without modifying the overall system. Another reason why separability is applied is portability and support for extension of peripherals. On the other hand, the separability in the definition introduces an interface between additional subsystems that can not introduce any "unacceptable effects", especially in terms of the characteristics of the system, which are not affected by telecommunications, Unacceptable distortion and signal degradation between systems, or loss of power through the Profile Connectors, loss of power in millivolt loss, will become the primary design criteria for functionality, so the power demand for the motherboard will also increase.

The limits of separability requirements and "unacceptable" are determined by the application of the Profile Connectors. The separable 4 includes the number of mating cycles, which means that the Profile Connectors must be provided without affecting its performance, as well as the forces necessary to cooperate with the other Profile Connectors. Typical mating cycles require tens of cycles from the internal Profile Connectors to thousands of cycles of peripheral devices, such as PCMCIA type Profile Connectorss. The demand for forces is even more important due to the increase in the number of circuits or functions and the interconnection of the Profile Connectorss. In order to provide more functionality, the position of the terminals on the Profile Connectors must also be increased, resulting in a higher Profile Connectors fit. Depending on the use and function of the Profile Connectors, the number of terminals from tens to thousands of different.

The principle of the Profile Connectors:

The so-called Profile Connectorss are two or more containers that are connected to each other below the liquid level.

The Profile Connectors has the same liquid, but the pressure on the liquid level is not equal, then the pressure difference between the liquid level is equal to the pressure difference between the liquid level difference between the two containers.

The pressure on the surface of the Profile Connectors is equal, but there are different liquids on both sides. The height of the two surfaces is inversely proportional to the density of the liquid.

The principle of the Profile Connectors has a wide range of applications in engineering. Such as various liquid level meter (water level gauge, oil level gauge, etc.), mercury vacuum gauge, liquid column pressure gauge, differential pressure gauge, etc., are made using the principle of Profile Connectors.

Category of Profile Connectorss:

The structure of the Profile Connectors is increasingly diversified, new structures and applications continue to emerge, trying to use a fixed model to solve the classification and naming problems, has become difficult to adapt. Some basic categories are still valid.

The definition of the Profile Connectors in our country

In China's industry management, the Profile Connectors and switch, keyboard, etc. collectively referred to as electrical Profile Connectors components, and electrical Profile Connectorss and relays are referred to as electromechanical components.

The product category of the Profile Connectors

Profile Connectors product type of division Although some confusion, but technically, the Profile Connectors product category only two basic division: ① by the shape of the structure: round and rectangular (cross-section), ② by operating frequency: low frequency and high Frequency (bounded by 3MHz).

In the above division, the coaxial Profile Connectorss are round and the printed circuit Profile Connectorss are rectangular (historically, the printed circuit Profile Connectorss are indeed separated from the rectangular Profile Connectors) and are currently popular The rectangular Profile Connectors has a trapezoidal cross section, approximately rectangular. To 3MHz for the boundaries of low frequency and high frequency and radio frequency division is basically the same.

As for the other uses, installation, special structure, special performance, etc. can also be divided into many different types, and often appear in the publications and manufacturers of promotional materials, but generally only to highlight a feature and use, the basic classification is still Did not exceed the above division principle.

Taking into account the technical development of the Profile Connectors and the actual situation, from its versatility and related technical standards, the Profile Connectors can be divided into the following categories (sub-categories):

① low frequency circular Profile Connectors;

② rectangular Profile Connectors;

③ printed circuit Profile Connectors;

④ RF Profile Connectors;

⑤ fiber Profile Connectors.

The model name of the Profile Connectors:

The model name of the Profile Connectors is the basis for the customer's production and the manufacturer's production. In the domestic and international Profile Connectors industry, the product model name has two kinds of ideas: one is to use the letter code plus digital approach, and strive to reflect the name of the product in the main structural features. The benefits of this approach are easy to identify, but the arrangement is too long, too complicated, with the miniaturization of the Profile Connectors, to print a lot of difficulties. At present, China is still popular in this way, and in some industry standards or even made in the national standard, such as SJ2298-83 (printed circuit Profile Connectors), SJ2297-83 (rectangular Profile Connectors), SJ2459-84 (ribbon cable connection Device), GB9538-88 (ribbon cable Profile Connectors) and so on.

Due to the increasing diversity of the Profile Connectors structure, it is becoming increasingly difficult to cover a certain type of Profile Connectors with a naming convention in practice. Another idea is to use Arabic numerals. The benefits of this approach are concise, easy to print for computer management and logo for small products. The major international Profile Connectors manufacturers are currently using this approach. It is expected that the naming scheme that reflects the characteristics of the manufacturers will gradually replace the way in which a naming convention is prescribed by the whole industry under the planned economy system.
