Introduction of Industrial Connectors
1. Easy to plug and unplug, anti-vibration does not fall off.
For example, under vehicle conditions, adapting to strong vibration environment is a rigid requirement. In the design and testing of industrial connectors, the plug-in force has been frequently plugged and unplugged for many times, and it is smooth and free of resistance. In addition, the snap lock is firm and reliable, with a large holding force, and it is rock-solid under the external vibration working environment, and will not cause loosening, poor contact or falling off;
2. Under continuous operation, the temperature rise fluctuation is small.
The temperature rise change during continuous operation is a key indicator within the safe range. The industrial connector will work continuously for a long time due to the long-term input DC power and output AC power of the machine. The industrial connector adopts high-quality materials, and continuously improves the contact coating and process of the contact body, which can meet the problems of small temperature rise fluctuation, no overheating or failure under high current and high voltage conduction, and is safer and more reliable to use;
3. Excellent waterproof performance, no worries in humid environment.
Waterproof is also a very important survey indicator for connectors in humid environments or outdoor environments, which is not only related to the connection performance of the connector, but also to the safety of use. The industrial connector can meet the waterproof requirements of IP65 and above in the connected state, and can meet the waterproof requirements of the inverter. If users have stricter and higher waterproof requirements in actual application scenarios, they can choose products with higher waterproof grades such as IP67 or IP68 to meet higher customer requirements;
4. Outstanding corrosion resistance, suitable for harsh environments.
Some industrial or outdoor environments present a potential risk of salt spray corrosion. Industrial connectors are mainly made of PBT plastic, which is highly resistant to salt spray acid corrosion and can effectively protect the connector shell and internal equipment from corrosion.
Four categories of industrial connectors
1. Current classification:
The current of industrial plugs and sockets is generally specified as: 16A, 32A, 63A, 125A and other series;
2. Voltage classification:
Voltage regulations are: 110V, 220V, 380V and other series;
3. Classification of the number of cores:
Standard 3-pin industrial plugs and sockets have a voltage of 220V-250V, and the shell color is blue; 4-pin and 5-pin industrial plugs and sockets have a voltage of 380V-415V, and the shell color is red;
4. Waterproof grade classification:
The general regulations are: IP44 and IP67, the maximum current of IP44 is 63A, and the maximum current of IP67 is 125A.
Four connection forms of industrial connectors
1. Thread connection:
Some large contactors and electrical connectors that work in strong vibration environments often use the connection form. This form of connection allows fuses to be installed after the connection is made to prevent loosening. The connection form is reliable, and the disadvantage is that the connection and unloading speed is slow.
2. Bayonet connection:
The bayonet connection is a reliable and fast form of connection and disconnection. Most industrial connectors in the form of snap connections have a visual display of correct connection and locking, which can be observed from the small holes on the side of the industrial connector coupling nut.
3. Plug-in connection method:
It is a versatile form of connection. When the plug of the industrial connector is disconnected from the socket, their moving direction is usually a reciprocating linear motion, which does not require twisting and rotation, and only requires a small working space to complete the connection and unloading. Common plug-in connections come in two configurations: ball or pin. Since there is no mechanical labor-saving mechanism, once inserted by mistake, the mechanical resistance will increase significantly, and the problem can be found in time.
4. Cabinet connection:
The cabinet connection type is used for industrial connectors on some equipment near the frame that need to be blindly connected, which can make electrical equipment lighter and smaller, easier to maintain, and more reliable. This form of connection makes the operator feel the connection, so it is necessary to design an accurate positioning device to avoid mis-insertion connectors being forced to connect together, making mis-insertion impossible. Cabinet electrical connectors are typically constructed with floating or spring contact designs to ensure proper connection.
