How to identify the connector’s high current and low current.

/0 Comments/in /by

How to identify the connector’s high current and low current? High current and low current is a relative concept when used. There are many differences according to  the use of different objects or different methods . How to clearly divide the currents? Now, let RENHOTEC‘s engineers give you a detailed introduction.

In general, the magnitude of the current is relative, if you want to determine the size of the current,then must start from its basic verification of the amount of electricity. Normally the rated current loop is rated , it will be a large current if it exceeds this rating . For example, if the charger’s current is 500mA, it is a small current in our eyes, but it is a large current when used on a charger .

Of course, the size of the current is related to the thickness of conductor. The current of the power supply reaches the load through the connector, the contact resistance between the pin and the socket, and the resistance of the pin and the socket itself, which together constitute the additional resistance of the circuit. And the load resistance is in series relationship. When the circuit current is large and the pin is small, the energy consumed by the additional resistor will cause the contact point to heat up. If the time is long, the pins and sockets will be oxidized and deteriorated, causing poor contact and entering a vicious circle until Broken circuit.

All in all, as long as the current is more than the planned current is a large current, if using the 500mA in the induction cooker, then the current should be a small current. Let’s take a look at the charger. At present, most of the currents we use are lithium-ion batteries, It can use a small current to charge, and also can use a large current , its speed much faster when using a large current.

It can be seen that the large current and the small current have no difference in the data, there will be some real explanations when there is a comparison, the reaction will be more obvious on the used object or on the limited value of the correlation.

/0 Comments/in /by

In the previous article, we talked and analyzed China’s Harsh Environment aviation connector standards, including the overview of China’s Harsh Environment aviation connector standards and various types of electrical connector standards and their application status. In this article, we will analyze problems in the Standard System of the Harsh Environment aviation connections in China.

China’s Harsh Environment aviation connector and China’s electrical connector industry started at the same time. Therefore, the standard system of Harsh Environment aviation connector has the same characteristics as the standard system of electric connector in China .

With respect to Harsh Environment aviation connector products, China’s Harsh Environment aviation connector companies, together with electronics and aerospace companies, can basically meet the needs of the aviation industry in terms of variety and productivity, in addition to individual high-tech products. However, there are still some problems in establishing a standard system for Harsh Environment aviation connectors. Mainly in the following areas:

  1. The basic material of the Harsh Environment aviation connector standard system table is not complete;
  2. The number of standards is small, there is a shortage of supporting standards and detailed specifications;
  3. The number of Harsh Environment standards for fiber optic connectors is relatively small. Although there are currently more than one hundred of these national standards, they are mainly applicable to the communications industry.

1.2. Standard of various electric connectors and their application status.

1.2.1 Circular electric connector standard.

Currently, the standard development of circular electrical connector supporting the air host and airborne requirements can be divided into three stages:

  1. In the 50-60s, stereotyped old models used the relevant standards of Russian series products.
  2. China’s self-developed standards for high-density medium-density series of products used in the established models in the 70-80s.
  3. The development of new aircraft since the 1990s mainly used the relevant national standards of the US standard products.

The standard of the above-mentioned electrical connector products shows three levels of low, medium and high technical level, which reflects the evolution process and development trend of China’s electrical connector standards. The circular electrical connector is basically complete in its current product standards, and plays an important role in the field of aviation aircraft. It can basically meet current needs.

1.2.2 Standards for Printed Circuit and Rejection Electrical Connector

Printed circuit electrical connectors are used for internal signal transmission of airborne equipment and are used in large quantities. The rectangular electrical connector is mainly used for the connection between devices and the wire connection between the inner panel and the board of the device.

The highly reliable wire spring structure is the main structure of China’s airline printed circuit electrical connectors and some rectangular electrical connectors since the 1980s. The highly reliable wire spring electrical connector product represents today’s most advanced contact structure.

There are 7 items of national standard for high-reliability wire spring structure printed wiring and rectangular electrical connectors, including 1 general specification for printed circuit electrical connectors, 5 items for detailed specification of printed circuit electrical connectors, and 1 item for rectangular electrical connectors.

There are 5 aviation industry standards for high-reliability wire spring structure printed wiring and rectangular electrical connectors, including 3 items  high-reliability wire spring structure and two standards for open-hole structure.

In the aircraft imported from Russia by China, its airborne equipment uses a large number of printed wire spring structure electrical connectors (1’PTIM, rpm-IM series) and framed rectangular connectors (PIIKM series). Accordingly, our country also introduced A large number of Russian corporate standards have basically satisfied production and demand.

China’s current standards for printed wiring and rectangular electrical connectors in terms of structure, installation, contact arrangement, contact spacing, etc., refer to the leaf spring structure standards (MIL-c-55302, DIN 41612, etc.), which can be more convenient with international standards. Connected. At present, the printed wiring and rectangular connector standards can basically meet the research and production requirements.

1.2.3 Standards for Coaxial Connector

This kind of connector is not the main industry of the aviation system connector manufacturer. The coaxial connector products used in the aviation industry are mostly ordered from the professional electronic system manufacturers, while the aviation connector manufacturers have very limited varieties of products. Orders of airborne equipment factories are mainly targeted at electronics and foreign companies. According to rough statistics, there are seven MIL series standards concerning coaxial connector products. Each standard includes hundreds of detailed specifications and detailed contents. There are more than 200 industry standards and national standards that are equivalent and equivalently used in China and are basically complete. In all types of connector products, the number of coaxial connector standards is the largest, basically meeting the requirements of aviation main and auxiliary. Machine factory needs.

1.2.4 Standards for Special Electrical Connector and Power Connector

There are many kinds of special electric connectors, including shedding, oil resistance, filtering, photoelectric mixing, photoelectric conversion, testing and so on.Such connectors have high reliability requirements, technical difficulties, and quantity requirements are generally small, but they are key products.There are few varieties of power connectors and single application domain, but it is very important for the connection of power transmission.At present, the standard number of special connectors is relatively small, with a total of 12 national standards, including II types, lacking detailed specifications, and the existing products basically carry out the enterprise standard.Standard power connector is only a recommended national standards (GB/I ‘13536), a specifications (GJB970) and a beacon (HB6184), more than 10 power supply the standard is not conversion.

Analysis of Current Status of Harsh Environment Aviation Connector Standards in China

/0 Comments/in /by

The General Situation of China’s Harsh Environment Aviation Connector Standards China’s Harsh Environment aviation connector standards can be divided into two categories according to system：the Russian system standard and the US Harsh Environment standard system. According to the level, it can be divided into three types: national Harsh Environment standards, industry standards and enterprise standards.

The Russian system standard refers to the standard of electrical connectors established by China during the imitation of a Russian electrical connector .

Due to specific historical reasons, Russian system standards is rarely appeared in the form of national standard (GB), national Harsh Environment standard (GJB), navigation mark (HB), electronic standard (si), but each product has enterprise technical conditions.

In the 1980s and 1990s, China transformed a large number of electrical connector standards in the U.S. Harsh Environment standards. And formulated the standard of the US Harsh Environment standard system. In order to be in line with international standards, most of the standards are converted using equivalent methods. According to incomplete statistics, by the end of 2001, there were 264 standards for electrical connectors in the US Harsh Environment standard system, among which there were 49 standards closely related to the aviation industry.

China’s Harsh Environment aviation connector manufacturing enterprises consist of four industry sectors: the electronics industry, the aviation industry, the aerospace industry, and the local Harsh Environment industry. In addition to the local Harsh Environment groups, all industries have their own electrical connector standards within the industry, but the number is small; relatively speaking, the national Harsh Environment electrical connector standard (GJB) even more than the industry standard; overall, most standards are in the form of corporate standards, and even industry standards are specific detailed specifications for products. General specifications are generally regulated by national Harsh Environment standards. In China, electrical connector standards are based on corporate standards. Even if national Harsh Environment standards have been issued, companies need to compile their own product technical conditions when organizing production, this results in a large number of corporate standards.

In addition, the Harsh Environment aerospace connector only refers to the connector used in the aerospace field. As for the standard used for electrical connectors, most of them are not specific. The product standards used in Harsh Environment aviation connectors originate from national Harsh Environment standards, aerospace, are basically same using for the standards ships, weapons, and electronics. Therefore, the general situation of China’s Harsh Environment aviation connector standards also basically reflects the outline of China’s Harsh Environment electrical connector standards.

What are aviation plugs? What are the basic components of aviation plugs? Now let’s learn together:

The basic structural parts of aviation plugs: 1 contact pieces; 2 insulators; 3 outer shells (depending on the different type); 4 accessories.

  1. Contacts are the core parts of the aviation plug to complete the electrical connection. A contact pair is generally composed of a male contact and a female contact, and the electrical connection is completed through the engagement of male and female contacts.

The male contact is a rigid part and its shape is cylindrical (round pin), square (square pin) or flat (insert). The male contacts are typically made of brass, phosphor bronze.

The female contact , the jack, is the key part of the contact . It relies on the elastic structure to be elastically deformed when inserted with the pin to generate elastic force to form a close contact with the positive contact to complete the connection. There are many types of jacks, including cylinder type (grooves, necks), tuning fork type, cantilever beam type (longitudinal grooving), folding type (longitudinal grooving, 9-character), box shape (square hole) as well as hyperbolic wire spring jacks.

 

  1. Insulators are alsonamed as bases or inserts. Their function is to align the contacts according to the desired position and spacing, and to ensure the insulation performance between the contacts and the housing. Good insulation resistance, withstand voltage performance, and ease of processing are basic requirements for the selection of insulating materials to be processed into insulators.

 

  1. The housing, also called the shell, is the outer cover of the aviation plug. It provides mechanical protection for the built-in insulating mounting plate and pins, and provides the alignment of the plug and socketwhen connecting, which fixes the aviation plug to the equipment.

 

  1. Attachments include structural accessories and mounting accessories. Structural accessories such as collars, positioning keys, positioning pins, guide pins, coupling rings, cable clamps, sealing rings, gaskets, etc. Install accessories such as screws, nuts, coils, etc. Most accessories have standard parts and common parts.
