What to look for in connector selection

1. Electrical parameter requirements: electronic connectors are electromechanical components connected to the electrical circuit. Therefore, the electrical parameters of the electronic connector itself is the first selection of electronic connectors to consider the problem. 2. additional voltage: additional voltage, also known as the operating voltage, which depends primarily on the connecting machine used in the insulation material, the spacing between the touch pair. Certain components or equipment below its extra voltage, may not be able to complete its due function. The additional voltage of the electronic connector should in fact be understood as a higher operating voltage recommended by the manufacturer. 3. additional current: additional current is also known as the operating current. The same with the extra voltage, in the case of less than the extra current, electronic connectors are generally able to operate normally. In the planning process of electronic connectors, electronic connectors through the thermal planning to meet the requirements of the extra current, because in the touch of the current flow period, because of the existence of conductor resistance and touch resistance, the touch of the pair will heat up. 4. touch resistance: touch resistance refers to the two touching conductors in the touch part of the resistance. In the selection of two issues to be noted, first, the electronic connector touch resistance target is in fact the touch resistance, which contains the touch resistance and touch on the conductor resistance. General conductor resistance is small, and thus touch to resistance in many technical specifications is called touch resistance. Second, in the connection of small signals in the circuit, pay attention to the given touch resistance target is tested under what conditions, because the touch surface will be attached to the oxide layer, oil or other contaminants, the two touching parts of the appearance of the film resistance will occur. 5. shielding: in modern electrical and electronic equipment, the density of the components and the related function between them is increasingly increasing, the electromagnetic interference puts forward a severe constraints. So the electronic connector is often closed with a metal shell to block the internal electromagnetic energy radiation or by the outside electromagnetic field disturbance. 6. insulation resistance: insulation resistance refers to the insulation part of the electronic connector voltage, so that the insulation part of the appearance of the leakage current within or on the appearance of the resistance value. It is mainly affected by the insulation material, temperature, humidity, dirt and other factors. 7. withstand voltage: withstand voltage is touching each other between the insulating part or insulating part and between the ground, in the rule of time can be accepted than the extra voltage is higher than the phenomenon of the critical voltage of the breakdown does not occur. It is mainly affected by the touching of the spacing and creepage distance and several shapes, insulator materials, as well as environmental temperature and humidity, atmospheric pressure.-8, on Evergrande Electronic Products Network platform related to the introduction and sales of products briefly: Evergrande Electronic Products Network - a professional agent / production / sales of a variety of {connectors | wiring harness | wire and cable products }; if you have a related [connectors | wiring harness | wire and cable products] purchasing / sourcing needs or would like to buy / to understand which connectors | harness | wire and cable products we can provide solutions, please contact the following Division I business personnel; If you have related [connectors | wire harness | wire and cable products] sales / resources and promotion needs, please click on the "¡¡ Business Cooperation ←" with the person to discuss!
