    Connector is our electronic engineering and technical personnel often contact of a kind of parts

    Connector is our electronic engineering and technical personnel often contact of a kind of parts. Its role is very simple: within a circuit was blocked place or isolated obstructed circuit between, a bridge, so that the current distribution, which makes the circuit to realize the function of the reservation. Connector is electronic equipment indispensable parts, the current of circulation channel observation, you will always find the has one or more connector. Connector form and structure is ever-changing, with application object, frequency, power, and application environment and so on the different, there are various forms of connector. For example, on the pitch with light of connector and hard disk drive connector, and lit the connector is not the same. But no matter what kind of connector, to ensure the current smooth continuous and reliable circulation. It refers to speaking, connector have on not only confined to current, in optoelectronic technology rapid development today, fiber optic system, transfer the signal carrier is light, glass and plastic instead of the normal circuit of the conductor, but light signal path also the use of connectors, their role and circuit connector the same.

    Imagine if there is no connector can be what kind of? At this time between circuit with continuous conductor permanently connected together, such as electronic device connected to the power supply, must the connection wire ends, and electronic device and power through some methods (such as welding) fixed joint firm. Circular shaft coupling this way, no matter for production or use, so it brought many inconvenience. With car battery, for example. Assume that the battery cable are fixed weld in battery, car factories for installation cell increases the work load and the increase of the production time and cost. Cell damage need to replace, and my car to the pit, sealing off demolition of the old, then welding on new, therefore have to pay more cost of labor. A connector can be exempt from many trouble, from the shop to buy a new battery, disconnect connectors, tearing down the old battery, with the new battery, to connect connector is ok. This simple example is given to illustrate the benefits of connector. It makes the design and the production process more convenient, more flexible, reduce the production and maintenance costs.

    The basic properties of the connector can be divided into three categories: namely mechanical properties, electrical properties and environmental performance. Another important mechanical properties are connector mechanical life. Mechanical life actually is a kind of durability (durability) index. It is a mesh, separation for a cycle, in order to in the provision of meshing, separation cycle connector can be normal complete its connection function (such as contact resistance) as evaluation basis.

    1. Mechanical properties. Is connected to the function character, insertion force is important to mechanical properties. Insertion force is divided into insertion force and drawing output (drawing output is also called the separation force), the requirement is different. In the standard has the largest insertion force and the minimum separation force regulation, this shows that, from the use of perspective, insertion force to small (and low insertion force LIF and without insertion force ZIF structure), and separation force if is too small, it will affect the reliability of the contact. Connector of insertion force and mechanical life and contact element structure (positive pressure size) contact parts coating quality (sliding friction coefficient) and contact element array size precision (alignment degree) about.

    2. Electrical properties. Connector main electrical properties including contact resistance, insulation resistance and resistance to electric strength.

    (1) the contact resistance of high quality electric connector shall have the low and stable contact resistance. Connector contact resistance from a few milliohm to dozens of milliohm inequality.

    (2) the insulation resistance measuring electric connector contact element, and between contact element and shell between the insulation performance of the indicators, the order of magnitude for hundreds of mge to thousands of mge inequality.

    (3) resistance to electric strength or say withstand voltage, medium pressure, is the representation connector contact element or between contact element and shell between tolerance rated test voltage ability.
