The screwed connector uses the pressure generated by tightening the screw to squeeze the conductor core through the contact surface of the tail of the crimping screw to form a stable connection point between the conductor core and the conductive material of the connector so as to realize the smooth running of the whole current signal loop. 

EW-M25I power connector come in different contact pins, the pin refer to the number of conductor cores of the connected cable and this will vary depending on the different real world applications.

The 2-core connector above is used for jointing two core wires. For AC wires, the connecting head is for the fastening of live wire and the neutral wire respectively. We mark ‘L’ and ‘N’ sign for you to easily distinguish. For DC wire, the screw locking connector is mainly responsible for the line connection of positive and negative terminals. The acceptable conductive wire core cross section range of the EW-M25I linear connectors is about 0.5-4.0mm².

Three-core wire is also very common in daily life, such as AC wire- live wire, neutral wire, ground wire. In general, when connecting lighting fixtures, the power connector used between the mains and the LED driver power is 3-core connector. A 3P waterproof connector is also useful and appropriate for other commonly used three-core wire extension splicing.

Four-core cables usually have three phase wires and one neutral wire, and are commonly used in TT power supply systems. TT power supply system refers to the protective system that directly ground the metal shell of electrical equipment, known as protective grounding system, also known as TT system. 

The first symbol T represents the power system neutral point direct grounding; The second symbol T indicates that the metal conductive part of the load device that is exposed and not connected to the charged body is directly connected to the earth and It has nothing to do with how the power supply system is grounded.

All grounding of a load in a TT system is called protective grounding. Three phase four wires system is generally used in such power supply systems. 4-core connector waterproof connector is required to connect wire in such a power supply system .  

In addition, the 4-core connector can also be used in the control line splicing. The number cores of the control line is relatively more. For example, you can use the 4P connector UL connector to connect the DMX512 control cable of the stage light.

The five-core wire is composed of five insulated core wires with a plastic sheath or steel armor sheath. Five-core cable is commonly used in three-phase five-wire TN-S low-voltage power supply line system. Moreover,five-core wires are also commonly used in MIDI device connections. MIDI is an industry standard electronic communication protocol.

 It can be used to connect the stage lamps , stage equipment and display screen matrix, realizing the communication adjustment, synchronization between each other ,Enabling instant exchange of data. A similar situation also can be found in the connection of the color change wall washing light, and other lamps and lanterns that need multi-frequency transformation and so on. I will not list them here. 

So a five-core connector can be a lamp connector, but also can be a device connector, stage lamp connector, wall washing lamp connector, signal connector, display screen connector, electronic musical instrument connector, industrial control connector, stage equipment connector ,etc.
