The wireless projection function means that the projector is connected to the local area network through a standard wireless transmission protocol so as to realize management, control, fault diagnosis, and the like in the local area network. The computer that is in the same LAN as the wireless projector can perform operations on the projector through authorization. For example, the projector in the conference room can be controlled directly in the office.
Wireless projection has two connection modes: Easy connect mode and Access point mode. The so-called simple connection mode is that the computer directly communicates with the wireless network card of the projector through the wireless network card, and no other equipment is needed in the middle. The access point connection mode is through the computer through the wireless gateway and the projector for signal transmission.
Currently, most wireless network projections on the market have the function of no PC presentation, support for USB memory, and PC memory card, enabling PC-free application solutions. In a wireless local area network, the projector can realize one-on-one, many-to-one, and one-to-many connection projection functions with the computer.
Industrial plugs, sockets and couplers are mainly divided into four categories: plugs, sockets, connectors and appliance input sockets, which are generally collectively referred to as industrial plugs. Its main features are as follows:
1. Safe and reliable
â‘ This kind of product uses the color of the shell to indicate the rated voltage, such as: 40V-45V is purple, 110V-130V is yellow, 200V-250V is blue, 230V-415V is red, and 500V is black. It is easy to distinguish, and you can't get it wrong.
â‘¡Different specifications have different diameters, pole numbers, and grounding contact positions. Only the same specifications can be plugged in to prevent misplugging.
â‘¢There is protection against electric shock. The grounding pole insert sleeve in the socket is longer than the phase pole and neutral pole insert sleeve, so as to ensure that the grounding pole is connected before the phase pole is connected when the plug is inserted, and the grounding pole is finally separated when the plug is pulled out. It is very safe to use.
â‘£Holding devices are provided to clamp the plugs and sockets to prevent them from falling off after being inserted, which improves the reliability.
⑤High protection level. There are IP44 splash-proof type, IP67 anti-immersion type and so on. Not only the human body cannot touch the live parts, but it can also be used under different environmental conditions to ensure safety.
â‘¥An elastic band is added to the insert sleeve. Ensure close contact, good conductivity and long service life after the plug is inserted.
⑦There is a cable clamping device, which can clamp the cable sheath, so that it will not be pulled off, and it is safe to use.
2. Durable
â‘ Good mechanical properties. The product shell is made of high-quality engineering plastic, which has high strength, impact resistance and is not afraid of falling. The rubber and plastic used have anti-aging properties and can be used not only indoors but also outdoors, and are durable.
②Heat resistance and flame resistance. The shell and internal insulating parts have heat resistance, the temperature can reach (100±5)℃, and the important parts can withstand (125±5)℃; and it is flame retardant.
â‘¢More resistant to plug and use. For example, for a product with a rated current of 16A, the number of normal plug-in operation cycles is more than 5000 times.
â‘£The temperature rise test of conductive contact parts shall not exceed 50K, which is suitable for long-term use.
3. Strong versatility
The products adopt the standards of GB/T 11918~11919-2001, which are equivalent to IEC 60309-1 and 2 standards, and are fully in line with international standards. Therefore, such products can be used both domestically and internationally. At the same time, it has a wide variety of specifications, which can meet various occasions and uses.
These characteristics of industrial plugs and sockets give it high safety, reliability and international versatility. Therefore, it has gradually received attention in the country. Through continuous promotion and application, industrial plugs and sockets have gradually entered various industries, such as electricity, ports, machinery industries and large-scale buildings. With the development of science and technology, industrial plugs and sockets are constantly innovating. Various quick installation technologies have been gradually applied to plugs and sockets, making it more convenient to use.
