DC power socket No matter what kind of connector, ensure smooth, continuous and reliable current flow. Generally speaking, the connector is not limited to current. In today's rapid development of optoelectronics technology, optical fiber system, the carrier of signal transmission is light, glass and plastic instead of ordinary circuit wires, but optical signal path also uses connectors, their role is the same as the circuit connector, mechanical properties in terms of connection function, Inserting and pulling force is an important mechanical property. Inserting and pulling force is divided into inserting force and pulling force (also known as pulling force), and the requirements of the two are different. In the relevant standards, the maximum insertion force and minimum separation force are specified, indicating that from the point of view of use, the insertion force should be small (resulting in a low insertion force LIF and no insertion force ZIF structure), and if the separation force is too small, The inserting force and mechanical life of the connector are related to the structure of the contact parts (positive pressure) and the quality of the coating at the contact parts (sliding friction coefficient) and the dimensional accuracy of the contact parts (alignment degree).Video and audio products, notebook, tablet, communication products, household appliances Security products, toys, computer products, fitness equipment, medical equipment Mobile phone stereo design, earphone,CD player, wireless phone, MP3 player, DVD, digital products DC power socket can be used in many places, not only limited to computer products, for example, we often see the type of video and audio products, whether DVD products or audio products, or MP3MP4 can use this socket. Secondly, digital cameras in digital products, as well as digital cameras can be used. This kind of socket remote control can also use this kind of socket, in addition to communication products can also use this kind of socket, in the household appliances, the human body electronic scale, as well as electric fans, rice cookers, kitchen scales, microwave oven TV and other products, can use this kind of DC power socket.
