Connector, CONNECTOR. Domestic also known as connectors, plugs and sockets. Generally refers to the electrical connector. That is connected to the two active devices, devices, transmission current or signal.
Connectors are a type of component that our electronic engineers often come into contact with. Its role is very simple: in the circuit is blocked or isolated barrier between the circuit, set up a bridge of communication, so that the current flow, so that the circuit to achieve the intended function. Connector is an indispensable part of electronic devices, along the current flow path observation, you will always find one or more connectors. Connector form and structure is ever-changing, with the application object, frequency, power, application environment, there are different types of connectors. For example, the lighting of the stadium connector and the hard drive connector, and the rocket ignition connector is very different. But no matter what kind of connector, must ensure that the current flow smoothly and reliably circulation. In terms of general terms, the connector is not only connected to the current, in the rapid development of optoelectronic technology today, the optical fiber system, the signal carrier is transmitted light, glass and plastic instead of the wires in ordinary circuits, but the optical signal Connectors are also used in the pathways, and they function the same as the circuit connectors.
The basic performance of the connector can be divided into three categories: mechanical performance, electrical performance and environmental performance. Another important mechanical property is the mechanical life of the connector. Mechanical life is actually a durability indicator. It is a meshing, separated into a cycle, to the provisions of the meshing, separation cycle after the connector can normally complete its connection functions (such as contact resistance) as a judge. 1. Mechanical properties With regard to the connection function, insertion and removal forces are important mechanical properties. Plug into and out of force into the pull-out force (pull-out force also known as the separation force), the two requirements are different. There is a maximum insertion force and a minimum separation force in the relevant standard, which indicates that the insertion force is small from the point of view of use (thus, there is a structure with a low insertion force LIF and a non-insertion force ZIF) and the separation force is too small, It will affect the reliability of the contact. Connector insertion and removal forces and mechanical life and contact structure (positive pressure size) Contact quality of the coating (sliding friction coefficient) and the contact arrangement of dimensional accuracy (alignment) on.
