4. Separation of plug and socket connections

Mechanical action between the shell parts helps industrial connectors plug and socket connection, locking, and separation. Shell must be matched to achieve its guidance and positioning.

5. Installing fixed connectors

Aviation plug connectors are usually fixed to panels or equipment with flanges or threads.

6. Fixed cable

When flexible cables are threaded into the industrial connector, they will be twisted and wobbly. The industrial connector can be more tightly fixed.

7. Electrical shielding (shielded version only)

Industrial connectors with shielding must have an all-metal electrical shielding structure. This helps to protect the interior of the aviation plug connector.

8. Presentation of visual aesthetics and product functionality integration

Today’s industrial connectors emphasize visual aesthetics and functionality. Consumers prefer industrial-style products.

What is the difference between an industrial plug and an ordinary plug?

1. Industrial plugs and ordinary plugs are different. Ordinary plugs have three or two flat copper teeth, while industrial plugs are cylindrical. Industrial plugs use a cylindrical jack structure because they need a lot of current. Industrial sockets and plugs are combined to meet the needs of different factories and businesses. Industrial plugs are made of thicker material because they are tested in more extreme conditions.

2. How they perform in different environments affects their waterproofness. Industrial plugs are used in factories and outdoors, where rain and snow are common. Industrial plugs must be waterproof to work in these environments. They must also be used with industrial sockets. IP44-rated industrial plugs are perfect for outdoor use.

3. Industrial plug cables are special rubber-jacketed cables. Cables for civilians can only be used in temperatures below 50 degrees, but industrial plug cables can be used below -50 degrees. The cables will not harden, and the cable cores can be used in temperatures below 65 degrees.

Industrial plugs are used in high-power machinery, so they must be heat-resistant. PC polycarbonate alloys are used for industrial socket panels. These panels are flame retardant, fireproof, impact resistant, and tough. They can be used safely in temperatures from -60 to 120 degrees, extending the service life of industrial plugs and sockets.

4. Industrial plugs and sockets are used in different ways.Industrial plugs and sockets are commonly utilized with machinery. Plugs and sockets can generally be used as multi-function sockets.

What about the foreground of the industrial connectors?

1. The global industrial connector market is growing. This is mainly because of new energy vehicles and 5G base stations. China is one of the largest connector markets in the world. It is expected to exceed 150 billion dollars by 2028.

Transportation grew by 17.2%, automotive by 14.6%, and industrial connectors by 8.5%. This shows that industrial connectors in the telecommunications and data communications industry are still important.

2. As technology improves, so do connectors. They are becoming more efficient and smaller. Connector design is becoming more sophisticated to meet the needs of high-frequency and high-speed transmission. Also, intelligent manufacturing and automation technology make high-performance industrial connectors more popular.

3. Connector applications are growing fast. They are used in many areas, including cars, phones, and factories. New growth opportunities have come from developing these emerging areas for the connector industry.

4. While big international companies like Tyco and Amphenol still lead the market, Chinese companies are catching up through innovation and expansion. This is creating opportunities for local businesses.

5. The market is optimistic, but the industry faces challenges like supply chain disruptions, labor shortages, and global conflicts. These could affect the manufacturing industry, especially in North America and Europe. The global economy and geopolitical issues also pose risks to the industry’s future.

A high-voltage connector is a specialized connection device utilized to transmit high-voltage electrical energy, signals, and data signals. It is typically employed to link high-voltage equipment in a range of fields, including electric power, telecommunications, broadcasting, aerospace, military, and medical equipment.

High-voltage connectors are designed for ease of use and installation, with a focus on safety and reliability. They offer high-voltage strength, good sealing, good insulation, and corrosion resistance, among other features. They can support up to 1000 V or more voltage and up to 20 A or more current, with high-frequency, high-speed, and high-strength signal transmission capabilities.

What are the product structures of high voltage connectors?

The structural design of high-voltage connectors must consider the transmission of high voltage, system stability, safety, and durability, as well as other factors. The high-voltage plug is the connector of the “mother head,” primarily through the needle lead, pin seat, and plastic shell composition. The needle-type lead is utilized to transmit electrical energy or signals. The pin seat is employed to fix the lead and to ensure the stability of the high-voltage system. The plastic shell serves to protect the lead and the pin seat, and in conjunction with the socket, prevents poor docking, scratches, and short-circuit problems.

The high-voltage socket is the primary component of the connector. The hole-type contact socket, fixed screws, and plastic shell are the main components of the hole-type contact. The socket is used to accommodate the contact, while the screws are used to fix the socket to the equipment. The hole-type contact is used to accept the plug pin-type lead conductor. The plastic housing protects the circuitry within the eyelet contacts and receptacle, as well as preventing contaminants and moisture in the foreign atmosphere from affecting performance during operation and use.

The installation of a high-voltage plug and socket combination is dependent on the intended use. The appropriate contact surface and socket caliber must be selected, and the connection must adhere to safety protocols to prevent accidents.

The installation of high-voltage plugs and sockets must be carried out in accordance with the actual use of the occasion. The appropriate contact surface and socket caliber must be selected, and attention must be paid to safety protection to prevent accidents during the connection.

High-voltage connectors are available in a variety of materials, including copper alloy, hard rubber, nylon, and high-voltage heat-shrinkable materials. Copper alloy is the main material used for high-voltage plugs, offering ideal conductive properties and good corrosion resistance. This makes the plug more reliable for use in harsh atmospheres and moisture.

Hard rubber is typically employed in another component of the high-voltage plug, primarily distinguished by its excellent insulating properties and high resistance to pressure. Additionally, it safeguards the pin lead and pin seat within the plug against thermal expansion and contraction.

Another commonly used material for plug-ins is nylon. Nylon is used in the shell part of the manufacturing process and offers a number of advantages, including vibration resistance, abrasion resistance, and effective resistance to a variety of chemical corrosion.

Furthermore, the design of the crimp plug-in is typically based on the specific requirements of the application environment, operating frequency, voltage, current, protection, and other elements. This necessitates the development of rigorous specifications and design procedures by manufacturers to ensure that their products comply with international and industry standards.

What are the functions of the high voltage connector?

1. Transmission of High Voltage Electrical Energy or Signal

High-voltage connectors are used to transmit high-voltage electrical energy or signals, enabling the connection and communication between various equipment. This includes voltage testing instruments, high-voltage discharge devices, medical equipment, and electric vehicles. High-voltage connectors are essential for these applications, as they facilitate the transmission of high-voltage electrical energy or signals.

2. Support High Voltage and Current

High-voltage connectors are capable of supporting up to 1000V or more voltage, withstanding up to 20A or more current, and have a frequency, high speed, high strength signal transmission ability. They play a vital role in various fields of high-voltage power supply and high-voltage testing.

3. To provide security and protection

High-voltage connectors are moisture-proof, waterproof, dust-proof, explosion-proof, and so on, which can protect the equipment from the effects of the external environment and damage. Furthermore, it can also provide security to prevent high-voltage exposure, thereby protecting the safety of operators.

4. Improve efficiency and reliability

High-voltage connectors facilitate the quick and easy connection and disconnection of equipment, enhancing work efficiency. They also enhance the reliability of the equipment by preventing issues such as poor contact, corrosion, short circuits, disconnection, and electrical interference.

The post Understanding of high voltage connectors: Structure, materials, and function first appeared on suqinszconnectors.com.

1. Precision manufacturing technology: This technology is mainly used for technologies such as small distance and thin thickness, which can ensure that the ultra-precision manufacturing field reaches a high level among the world’s peers.

2. Light source signal and electromechanical layout combined development technology: This technology can be applied to audio car connectors with electronic components. Adding electronic components to car connectors can make car connectors have two functions, breaking the traditional design of car connectors.

3. Low temperature and low-pressure molding technology: In the manufacturing process of car connectors, the sealing and physical and chemical hot melt functions are used to make the car connectors achieve the effect of insulation and temperature resistance. After encapsulation, the wire ensures that the welding points are not pulled by external forces, ensuring the quality and reliability of car connector products.

Determine whether the auto connector has high reliability?

1. High-reliability connectors should have stress relief function:

The electrical connection of automotive connectors usually bears greater pressure and stress than the board connection, so connector products need to have stress relief functions to improve their reliability.

2. High-reliability connectors should have good vibration and impact resistance:

Automobile connectors are often affected by vibration and impact factors, which leads to connection interruption. To deal with such problems, connectors must have good vibration and impact resistance to improve their reliability.

3. High-reliability connectors should have a solid physical structure:

Unlike electrical connections separated by electric shock, to deal with adverse factors such as impact in special environments, connectors must have a solid physical structure to prevent the connectors from damaging the contacts during the pairing process due to adverse factors, thereby improving the reliability of the connectors.

4. High-reliability connectors should have high durability:

General automotive connectors may have a plug-in service life of 300-500 times, but connectors for specific applications may require a plug-in service life of 10,000 times, so the durability of the connector should be high, and it is necessary to ensure that the durability of the connector meets the standard requirements of the plug-in cycle.

5. The operating temperature range of high-reliability connectors must meet the specifications:

Generally, the operating temperature range of automotive connectors is -30°C to +85°C, or -40°C to +105°C. The range of high-reliability connectors will push the lower limit to -55°C or -65°C, and the upper limit to at least +125°C or even +175°C. At this time, the additional temperature range of the connector can generally be achieved by selecting materials (such as higher-grade phosphor bronze or beryllium copper contacts), and the plastic shell material needs to be able to maintain its shape without cracking or deforming.

What are the requirements for the sealing test of automotive connectors?

1. Sealing test: It is required to test the sealing of the connector under vacuum or positive pressure. It is generally required to seal the product with a clamp under positive or negative pressure of 10kpa to 50kpa, and then conduct an airtightness test. If the requirement is higher, the leakage rate of the test product shall not exceed 1cc/min or 0.5cc/min to be a qualified product.

2. Pressure resistance test: The pressure resistance test is divided into negative pressure test and positive pressure test. It is required to select a precise proportional control valve group for testing and vacuum the product at a certain vacuum rate starting from the initial pressure of 0.

The vacuuming time and vacuum ratio are adjustable. For example, set the vacuum extraction to -50kpa and the air extraction rate to 10kpa/min. The difficulty of this test is that the airtightness tester or leak detector is required to set the initial pressure of the negative pressure extraction, such as starting from 0, and of course, the extraction rate can be set and changed, such as starting from -10kpa.

As we all know, the sealing tester or airtightness tester is equipped with a manual or electronic pressure regulating valve, which can only adjust the pressure according to the set pressure. The initial pressure starts from 0, and the ability to evacuate depends on the vacuum source (vacuum generator or vacuum pump). After the vacuum source passes through the pressure regulating valve, the evacuation speed is fixed, that is, it can only be evacuated from 0 pressure to the fixed pressure set by the pressure regulating valve instantly, and it cannot control the evacuation pressure and time into different proportions.

The principle of the positive pressure withstand test is similar to that of the negative pressure withstand test, that is, the initial positive pressure is set to any pressure, such as 0 pressure or 10kpa, and the gradient of the pressure rise, that is, the slope can be set, such as 10kpa/min. This test requires that the pressure rise can be adjusted proportionally with time.

3.Rupture test (burst test): divided into negative pressure rupture test or positive pressure rupture test. It is required that when the vacuum is evacuated or pressurized to a certain pressure range, the product should rupture instantly, and the rupture pressure should be recorded. The difficulty of the test is that the negative pressure obtained by the air tightness tester meets the requirements of the second test, the pressure rate is adjustable, and the pressure blasting must be completed within the set range and cannot exceed it.

That is to say, blasting below this range or blasting above this range does not meet the product test requirements, and the test pressure of this blasting point needs to be recorded. This kind of measurement requires an anti-riot device. Usually, the anti-riot device places the test workpiece in a pressure-resistant stainless steel cylinder, which needs to be sealed, and a high-pressure relief valve needs to be installed on the stainless steel cylinder of the outer cover to ensure safety.

3. Wires slip or loosen on automotive terminals.

*Terminals and wires don’t match well：Choose matching terminals and wires for a solid connection.

*The terminal surface is too smooth,so the wire doesn’t stick well：If necessary, in the terminal surface for some treatment, increase its surface roughness, so that the wire is better fixed.

*Uneven crimping: Make sure the crimping is even to avoid uneven or irregular crimps at the terminal, which may cause the wire to slide or loosen.

4. Wire breakage after auto terminal crimping.

*Conductor cross-section is too fragile or has damage: use the wire to meet the requirements to ensure that the size and quality of its cross-section meet the crimping requirements.

*If the crimping force is too large, resulting in wire damage or breakage: adjust the strength of the crimping tool.

*Poor connection between conductor and terminal: Make sure the connection between terminal and conductor is firm and reliable.

5. Overheating after automotive terminal connection.

*Poor contact between terminals and wires, resulting in increased contact resistance and excessive heat generation: Ensure good connection between terminals and wires to avoid overheating caused by poor contact.

*Terminal or wire material is unsuitable for the application environment, resulting in overheating: Use terminals and wire materials that meet the requirements of the application environment, to ensure that they can work properly at high temperatures or other harsh conditions.

*Excessive current through the terminals and wires, exceeding their rated capacity: for high current applications, select terminals and wires that meet the requirements, and ensure that their rated capacity can meet the actual demand, to avoid overloading caused by overheating.
