DC power socket connection not only to be able to connect but also to understand the principle, and pay attention to the occurrence of some problems, these are the knowledge we all need.
DC power socket is widely used in daily life, but as our non-technical personnel, for DC power socket connection principle and other aspects of content is certainly less understood, as well as socket use notes. Then for the working principle of DC power socket and the use of information, we still need to know more about the use of socket to avoid some safety incidents. The last time I explained to you is what the advantages of DC power socket and other related knowledge analysis, then the following by a small edition for everyone to explain in detail the principle of DC power socket connection and the use of precautions.
DC power socket connection principle
The connection principle of DC power socket is that when the plug is inserted, the moving contact pin inside the power socket will be jacked off, thus cutting off the negative electrode path of the battery inside the circuit. When the power socket coil is energized, the iron core in the coil will produce a strong electromagnetic force, pulling the armature to drive the inner reed, so that the contact 1, 2 are disconnected. 3 feet connect the power supply access. The connection of the DC power socket is according to the left zero right fire on the ground, which means that the pin of the power socket is connected to the left zero line, the pin on the right is connected to the fire line, and the lead earth wire in the middle (upper) is connected to the ground.
Points for attention of DC power socket
Points for attention
When the plug is inserted into the DC socket, the contact is good. Do not pull it out too hard, or it will easily lead to loose contact between the plug and socket. So do not push too hard for plug and socket plugging.
Points for attention two
Regarding the use of the socket environment, in some kitchens and bathroom bathrooms where the water vapor is heavy, we should add a protective box to the DC power socket. If the water vapor is heavy, it will make the socket easy to short circuit and burn the socket.
Points for attention three
For some electrical equipment with large power, do not insert a DC power socket with small power, or the socket can not be loaded internally, so it is easier to damage the socket. Therefore, electrical equipment with different power should be selected according to the corresponding DC socket and plug.
Points for attention four
The DC power outlet should not be installed with many other sockets. Otherwise, the power of the operating current is relatively large when the multiple sockets are running, which is far beyond the scope of the DC power outlet. At this time, the DC power outlet can not afford to load, leading to the possibility of burning the socket.
Points for attention five
For the connection of DC power socket, its zero-wire ground wire must be connected to the corresponding socket pin, whether or not the socket is easy to cause human contact, as well as short-circuit accidents. So we should pay great attention to the wiring of sockets.
Points for attention six
If the plug of the DC power socket is broken, it should be replaced in time. If the plug is easy to be short-circuited or sparked, the serious point may cause the socket to fire.
Points for attention seven
Pay attention to the load of the DC power socket. In the actual use of the socket, the actual current and voltage parameters can not be greater than the rated value of the socket. Do not allow the socket overload operation, or will cause socket short-circuit fire and other accidents.
