What is a 12V socket?
12V socket is a cylindrical vessel that provides direct current (DC) at 12 volts to the device connected to it. The most commonly known 12V sockets are located in cars and were originally provided as part of a system that warmed a metal coil in the heat resistant to light cigars and cigarettes. Cigarette lighters are still provided in cars as optional accessories, but 12V sockets are still installed in cars as an energy source. It is not unusual to find some vehicles with four or five 12V stores that provide power to charge or operate a wide range of consumer electronics. When the coils were hot enough to ignite a cigarette or a cigar, the bimetallic belt would bend back, release the hook and activate the spring mechanism that jumped behind the lighter from the leaking out of the leaving the drawer. This indicated that the lighter was ready for use. 12V sockets installed in modern vehicles as power sources are usually not POSFlowers to withstand heat generated by a car cigarette lighter and users are warned against attempting to use them for this purpose.
Like all electrical sockets, the 12V socket must be connected to the energy source; This is usually the vehicle's electrical system. 12V sockets and their plugs, however, differ significantly from standard socket combinations and AC sockets). The most significant difference is that the 12V socket and plug are every cylindrical, while the male plug fits comfortably into the female drawer.
Inserting a 12V socket into the socket completes the circuit. Positive contacts are in the middle of the cylinders-the fleet lined with a plug of plugs. When the plug is safely seated in the socket, this rod is forced to against positive contact in the center of the socket.
The negative contact in the socket is its cylindrical inner surface, which is made of metal. Most modern 12V plugs have two flexibleThe negative contact strips protruding from their sides, which established contact with the metal interior of the plinth and maintain this contact if the plug remains inserted. The plug is built to fit closely into the socket; This, in conjunction with the striking of negative contact strips, keeps the plug safely inserted into the 12V socket.
Many portable electrical and electronic devices are built to operate on a normal household at 120 V AC and DC current, and can be connected to the 12V car socket. Another useful device is a device that converts 12V DC to 120 V AC. These devices have a 12V plug at one end and one or two standard 15-ambaches on the other.
