DC socket application and classification needs to explain to you, the usual place to use a lot, but everyone is not very clear, specific details to us to give you a brief introduction.
Speaking of the DC socket, a lot of people think of the socket and ignore the DC. We can see the socket directly, such as the Bulls socket, and the DC socket is only a kind of electronic component, the volume is relatively small, also called the DC power outlet, equivalent to a connector. Dc sockets are not only classified but also widely used. Mainly used in electronic and other related products, with the continuous development and progress of science and technology, people will not be able to design a variety of easy to use a variety of things on a number of previous products, such as the previous car is a very old-fashioned manual gear, but also the root there is no navigator, and now, there are not only A lot of other comforting equipment.
DC socket is so widely used, which is bound to be closely related to the principle of DC socket, we also tell the classification and application of the DC socket, we will discuss the following details:
Analysis of the principle of DC socket
When the power socket coil is electrified, the iron core in the coil generates strong electromagnetic force, and the armature drives the reed to disconnect the contacts 1 and 2, and to connect 1 and 3. When the coil is cut off, the spring restores the reed so that the contacts 1 and 2 are connected, and the 1 and 3 disconnect. We can use the DC socket to achieve certain control purposes by connecting the circuits that need to be controlled in 1, 3 (called normally open contacts) or 1, 2 (1, 2 called normally closed contacts).
If the DC SOCKET AC 220V rectifying filter circuit has a short circuit fault, and when the machine starts to burn insurance, it must first check whether the rectifier diode is short circuited and the filter capacitance is serious leakage. If you have it, you must change it in time.
Classification of Dc sockets
One, according to the use points: notebook DC socket, car DC socket, Bluetooth DC socket.
Two, according to the size of the center pin of the DC socket, it is divided into: 3.5dc socket, 3.0dc socket, 2.5dc socket.
Three, according to encapsulation: patch DC socket and plug-in DC socket. (1.65mm/1.3mm/1.1mm/1.0mm/0.7mm/0.5mm needs consulting business of equal size)
Application of Dc socket
First, thermometer, blood pressure meter, hospital call system and other medical equipment.
Two, treadmill, massage chair and other fitness equipment.
Three, cameras, recording pens, digital cameras, digital cameras, telephones, building equipment, mobile phones, car phones, PDA and other electronic digital products.
Four, visual interphone, monitor and other security products
Five, electronic body scales, electronic fat scales, TV sets, microwave ovens, rice cookers, electric fans, electronic kitchen scales and other household appliances and related products.
Although DC socket has so many advantages, the application of GF, but no matter what kind of products, there are perfect places, so DC socket is no exception. For DC sockets, we need to pay attention to the problems that are easy to be ignored when installing DC sockets. The following is as follows:
One, many electrical appliances share the same socket
Two. Lack of protective measures
Three. The conductors are installed at random
Four. Low position
Five. There is only one loop
