1. Preparation
Before connecting the Copper Tube Terminal Block to the wire, make full preparations. First, select the Copper Tube Terminal Block and wire of appropriate specifications. The specifications of the Copper Tube Terminal Block must match the wire diameter of the wire. If the terminal is too small, it may not be able to clamp the wire firmly, which may cause poor contact; if it is too large, it will cause unnecessary trouble during the connection process. At the same time, prepare suitable tools, such as wire crimping pliers. In addition, the ends of the wires need to be processed to remove the insulation layer. Be careful when removing the insulation layer to avoid damaging the metal wire inside. Generally, wire strippers are used to remove the insulation layer according to the specified length. Usually, the stripping length should be suitable for the depth requirement of inserting the Copper Tube Terminal Block to ensure stability after connection.
2. Connection operation
When the preparation is completed, the connection operation can be carried out. Insert the processed wire into the Copper Tube Terminal Block, and make sure that the wire is fully inserted into the bottom of the copper tube. This step is critical. If the wire is not fully inserted, it is easy to loosen during subsequent use, causing heat and even safety accidents. After insertion, use the crimping pliers to crimp the Copper Tube Terminal Block. The crimping pliers should select the appropriate crimping part and operate according to the specifications of the terminal. During the crimping process, sufficient pressure should be applied to make the Copper Tube Terminal Block tightly wrap the wire. Generally, multiple crimpings are required to ensure the firmness of the connection. Pay attention to the direction during crimping so that the crimping marks are evenly distributed on the Copper Tube Terminal Block to avoid excessive or insufficient local pressure.
3. Inspection after connection
After the connection is completed, it must be inspected. First, visually check whether the connection between the Copper Tube Terminal Block and the wire is firm and there is no looseness. You can gently pull the wire to see if it will come out of the terminal. Secondly, check whether the Copper Tube Terminal Block is over-deformed or broken. If too much pressure is applied during the crimping process, the Copper Tube Terminal Block may be over-deformed or even broken, which will affect the reliability and safety of the connection. Finally, you can also use professional tools, such as a resistance tester, to detect the resistance value of the connection part. Under normal circumstances, the resistance value between a well-connected Copper Tube Terminal Block and the wire should be very small. If the resistance value is too large, there may be a poor connection problem and the connection needs to be re-performed.
