Characteristics of industrial plug and socket and connector

Promulgator : DIHAO Date : 2018-06-13

Industrial Plugs And Sockets and couplers are mainly divided into plugs, sockets, connectors, and appliance input sockets. Generally referred to as industrial plugs and sockets.
Industrial plugs and sockets have the following features:

1. Safe and reliable

(1) This kind of product uses the shell color to express the rated voltage, if the blue represents 220V, the red represents 380V, at a glance, it is easy to distinguish, can not make a mistake.
(2) The diameter, number of poles, and position of ground contacts of different specifications are different. Only the same specifications can be inserted to prevent mis-insertion.
(3) Protection against electric shock. The grounding pole plug in the socket is longer than the phase pole and the neutral pole plug sleeve, which ensures that the plug is connected before the phase pole is connected and the grounding pole is finally detached when the plug is plugged in, and the use is very safe.
(4) High degree of protection. IP44 anti-splash type, IP67 anti-soaked type, etc. Not only can the human body not touch live parts, it can also be used under different environmental conditions to ensure safety.
(5) The elastic sleeve is added to the insertion sleeve. Ensure that the plug is tightly contacted, conductive and has a long service life.
(6) There is a holding device, so that plugs and sockets can be clamped and prevented from coming off after plugging. The reliability is greatly improved.
(7) There is a cable clamp device that can clamp the cable sheath so that it will not be pulled out and it is safe to use.

2. Durable

(1) Mechanical performance is good, and the product shell is made of high-quality nylon, which has high strength, impact resistance, and is not afraid of falling or stamping. All rubbers and plastics are resistant to aging and can be used not only indoors, but also outdoors, for durability.
(2) Heat and flame resistance. The housing and the internal insulating parts are heat-resistant, the temperature can reach (100±5)°C, the important parts can withstand (125±5)°C; and they are fire-retardant.
(3) more resistant to use plug. For products with a rated current of 16A, the number of normal plugging cycles is more than 5,000.
(4) The temperature rise test section of the conductive contact member (plug and socket) exceeds 50K and is suitable for long-term use.

3. Versatility

The product adopts the GB/T 11918~11919-2001 standard, which is equivalent to the IEC 60309-1/2 standard and is completely in line with international standards. Therefore, such products are common at home and abroad. At the same time, its variety of specifications can meet a variety of occasions and uses.
These features of industrial plug sockets make it highly safe and reliable and internationally versatile. Therefore, it has gradually received attention in the country. Through more than ten years of continuous promotion and application, industrial plugs and sockets have entered all walks of life, such as electricity, construction, port terminals, machinery industry and modern large-scale construction. The manufacturers have also grown from the initial few to the current hundreds. At the same time, with the development of technology, industrial plugs and sockets continue to innovate, and a variety of rapid installation techniques have been applied to plugs and sockets to make them more convenient.
