The plug-in series terminal blocks are used to realize electrical connection. The plug-in type quick terminal block series adopt the easy-to-operate pluggable connection and the solid and universal screw method to connect various parts. The plug-in quick terminal block is made up of two parts plugging and unplugging. One part presses the wire tightly, and then plugs it into the other part, which is soldered to the PCB board. The mechanical principle of this connection bottom, this anti-vibration design ensures the long-term airtight connection of the product and the reliability of the finished product. Mounting ears can be added at both ends of the socket. The mounting ears can protect the tabs to a large extent and prevent the tabs from being arranged poorly. At the same time, this socket design can ensure that the socket can be correctly inserted into the mother body.
Common problems when using:
1. Causes the problem of burning black:If the terminal is black, one of the possibilities is not necessarily burned black, oxidation may also be black. So how to verify whether it is burnt black? The method we take is to wipe it off with a finger. If it can be wiped off, like soot, it is a black substance formed by oxidation, which can only be wiped off with sandpaper or a file. One thing to note here is: don't wipe it with your fingers when it is electrified! Then another possibility is that it burns black.
2. Problems that cause high temperatures There are two possibilities: the terminal is loose and the contact resistance is too large, resulting in overheating; the terminal is not loose, but the circuit has overcurrent heating due to some unknown reason, such as the power supply voltage is too high, or the load is short-circuited. (1) The voltage is too high. You can check from the source, the secondary voltage of the transformer-the voltage in the distribution box-the voltage of the electrical equipment. (2) Ground fault. You can also find it from the transformer, and then go to the distribution box for grounding. The grounding should be grounded, and the normal phase line should be removed from the ground fault. You can use an insulation meter or a shaking meter to measure when the power is cut off, and measure in sections. Try to measure only the power supply and distribution lines such as cables, wires, circuit breakers, switches, etc., if it is really difficult to section, unplug the weak current equipment, The fuse of the sensing device.
The key to grounding is that the grounding resistance should be low and the contact area should be large. The former can ensure that the grounding point has a "zero potential" that is as low as possible close to the ground potential, which can avoid the possibility that lightning will return from the grounding line and enter the power supply loop after lightning strikes. The latter can ensure that there is enough capacity to provide a fault current channel, including lightning or short-circuit faults and so on.
