Ensures Smooth, Continuous And Reliable Current Circulation
- Jun 22, 2018 -

Connectors are a type of part that our electronics engineers often contact. Its role is very simple: in the circuit is blocked or inaccessible between the circuit, set up a bridge of communication, so that the current flow, so that the circuit to achieve the intended function. The connector is an indispensable part of the electronic device. Observe the path through which the current flows. You will always find one or more connectors. Connector forms and structures are ever-changing, and there are various types of connectors, depending on the application, frequency, power, and application environment. For example, connectors for lighting on the field and connectors for hard drives, and connectors for lighting rockets are very different. But no matter what kind of connector, we must ensure that the current flows smoothly and reliably. On the other hand, the connector is not only limited to the current, but today in the rapid development of optoelectronic technology, the carrier of the signal in the optical fiber system is light, glass and plastic replace the wires in the ordinary circuit, but the optical signal Connectors are also used in the vias, and they function as circuit connectors.

Mechanical properties Insertion force is an important mechanical property in terms of the connection function. Insertion force is divided into insertion force and pull out force (pull out force is also called separation force), the requirements of the two are different. In the relevant standards, the maximum insertion force and the minimum separation force are specified, which means that from the use point of view, the insertion force is small (thereby having a low insertion force LIF and no insertion force ZIF structure), and if the separation force is too small, It will affect the reliability of the contact.

Another important mechanical property is the mechanical life of the connector. The mechanical life is actually a durability index, which is called mechanical operation in the national standard GB5095. It is based on one cycle of insertion and one time of withdrawal to determine whether the connector can normally perform its connection function (such as contact resistance value) after a specified plug cycle. The insertion force and mechanical life of the connector are related to the plating quality (the sliding friction coefficient) at the contact portion of the contact structure (positive pressure) and the dimensional accuracy (alignment) of the contact arrangement.
