Heavy Duty Connectors (HDC connectors) are also called industrial connectors with it’s rectangular shape. Cause it has huge advantages in wire connecting, heavy-duty connector plays an important role in the connector market. When compared with traditional connecting ways, heavy-duty connectors with their pre-installation function largely improve the efficiency and quality of the connecting task, also making the project more cost-reducing. Heavy-duty connectors are designed to fit the very harsh working conditions, like dusty, rainy, vibrating, hot, and cold areas, to fulfill the task of transferring the signal and power data to achieve the control process of the device. We will talk in more detail about what is heavy duty connector, including structures, main technical specifications, advantages, and applications of our heavy-duty connectors.
1. Structure
Heavy Duty Connectors are combined with it’s hoods, housing, male and female inserts, and cable fittings. Below is the Main part of the whole set.
● Housing
The housing is the connecting mounting parts that will have four installation holes to connect with your device, and usually the housing will be together with a single lock or double lock to help the housing connect with the hoods. The housing of heavy-duty connectors is made of high-strength aluminium alloy. And normaly the female inserts will be settles by screws together the housing. Sometimes the housing will be with protection covers.
● Hoods
Hoods are also made of high-strength aluminium alloy, usually connected with male inserts. Industrial heavy-duty connector hoods are with low or high constructions, with side or top cable entry, 2 or 4 bolts, and 1 or 2 locking levers.
● Male inserts
Heavy Duty connector male inserts are made of polycarbonate, can work under the temperature from -40℃ to 125℃, the flammability according to UL 94 will be V0, and the mechanical working lifes (put in and pull out times) must be more than 500 times. The most important parts -pins are connected with the insert’s body in three ways below:
·Screw terminal
·Crimp Terminal
·Cage-Clamp terminal
● Female Inserts
Heavy-duty connector female inserts are also very important parts that connect with male inserts. Female inserts also have the same terminal type as male inserts, with a modular design.
● Heavy Duty Connector Cable Fittings
Heavy Duty Connector cable fittings will be with different types, like cable glands with normal or multiple sealing. Metal or plastic cable glands, special cable entry protection, or an extensive range of accessories.Depends on different devices and applications.
2. Specifications
HDC heavy duty connector it’s a very specific product with accordingly standards and test requirements.
● Current Carrying capacity
The heavy-duty connector’s current carrying capacity is limited by the maximum temperature of the materials for inserts and contacts. Control and test procedures will be according to DIN IEC 60512-3. Other specifications will be according to DIN VDE 0627, DIN VDE 0110, DIN EN 61984.
①：HE-6
②：HE-10
③ : HE-16,HE-32
④ : HE-24,HE-48
Heavy Duty Connector also with flexible choice of Current, from 10A to 110A. Rated Current 10A, usually according to HA, HD, and HDD type, as a compact design of heavy-duty connector.
● Pin Nos
Heavy-duty connector pins are the most important parts of the whole set, made of copper with silver plated to reduce the resistance and cost when connected with current. Also, HDC connectors have various pins, from 3 pins to 216 pins.
● Voltage
Heavy Duty Connectors provides a full range of voltages from small to large, including 250V, 400V, 500V, and 690V. Each voltage has its own type of heavy-duty connector, such as HSB, HK type is for high voltage. And for the rated impulsive voltage will be 4 kV and 6 kV.
● IP Class
Heavy-duty connectors are also called industry connectors because of it’s high IP class. As it’s high-strength aluminium alloy hoods and housing, together with the rubber gasket protection degree from IP65 up to IP69k, which means heavy-duty connectors can fit and be applied in harsh environments.
3. Advantages of Heavy-Duty Connectors
● Pre-Installation
Heavy Duty Connectors’ Modular design helps it achieve the pre-installation, only need to according the numbers on the inserts. It will highly improve the efficiency when facing large-scale and complex electric circuits. Also can avoid the error when connecting.
● Various Combinations
The Heavy Duty Connector design with flexible choice, high density, and compact design can achieve the operation in limited space, also provides high current and high voltage with different types of designs according to different applications.
● Easy installation and Use
Heavy Duty connectors are modular in design, whole sets are easy to dispatch and use. Modular design also makes the transmission of power, data, and signals easier and quicker.
● High-Level Protection
HDC heavy-duty connectors have IP65 to IP69K, which can fully resist dust, oil, rain, and snow. This allows for the device to be controlled and worked on in harsh and extreme climates.
4. Heavy-Duty Connector Applications
● Power and electrical area
Reliability, safety, economy, high energy, and environmental to power grid operation, computer technology, and heavy-duty connector and control technology are important ways to achieve this indicator.
Application Type: HA, HD, HE Type with high-rated power and compact design.
● Power and electrical area
Wind power generation is a power generation model with the most mature technology, the most favorable large-scale development conditions, and commercial development prospects among new energy sources. Heavy-duty connectors give the best support for the wind power generators.
● Hot Runner system connector/plastic injection molding
Hot Runner system it’s the critical part in the moldings. Heavy-duty connectors are connected to their temperature control system to perform the function of temperature control. Usually, it will be 16 pins and 24 pins for the hot runner system connectors.
●Automation Control/robot industry
After entering Industry 4.0, Robotics has played an important role in all fields of industry. His high efficiency and flexibility have made it an indispensable part of the industrial process, including flexibility and convenience in installation, use, production, and debugging. Heavy Duty Connector HE, HEE, HK, HM, and other series products meet the diverse and flexible needs of robots in different fields.
Other applications like railways, cranes, printing machines, laser cutting industry all need the heavy-duty connector to provide good and quick control ability for the system.
Heavy Duty Connector future
In a word, although heavy-duty connectors have powerful and reliable performance and diverse designs that can meet the current requirements of various fields, with the development of industrial progress, the continuous progress of various sub-sectors will produce new connection requirements and designs. And the heavy-duty connector will develop further along with the development of the market. UMER heavy duty connector will keep up with the market’s innovative consciousness and thinking, and provide customers with better and more innovative connection services.
