System design is becoming increasingly small, however, the power supply but demand is growing a tremendous challenge to the design engineer. This means that the power connector must also accommodate two conflicting necessary conditions is to increase the power of I is also designed to be more compact filter on the market an array of power connector, but I do not know how to proceed.

Key characteristics of the rated current, for example, which bears a lot of knowledge. The rated current is the amount of current the master terminal specific temperature, usually 20 ° C or 30 ° C. Proper use of this data should be aware of its test methods, but also pay attention to the test environment. For example: Some simple test a pair of phase, but is not installed in the enclosure of female terminal and male pin. As we all know, connector warming factors, including the contact resistance, current, and thermal channels.

In practical applications, the mother of public needles terminal is installed in the enclosure. Therefore, the cooling channels of the sharp decline. Coupled with the general use more than one contact, but can not be set to the rated peak current operating current of the connector. From a production point of view, the traditional power connector mostly lathe. Based on the maturing of the stamping technology, which gives rise to a new generation of metal forming, power connector. In contrast, the lathe process is relatively simple, abrasive set time is short, is a more flexible production technology. Metal forming processes, although more expensive, but in volume production, its cost and lathe comparable partial plating of metal forming technology allows the lathe can not provide the option. From a qualitative point of consideration, the conditions of long-term production, stamping molding to ensure a certain quality of stability, which is lathe can not be compared.

From the assembly point of view to explore the circuit board assembly, crimping, paste or welding; cable assembly to connect the screws, welding, routing, grinding then and the IDC (commonly known as punctured connection or insulation displacement connection). Please select the appropriate connector, to consider not only the price of the connector, the more important factor is the appropriate assembly technology. Welding connector is naturally cheaper than the surface-mount and crimp connectors, without high-temperature plastic shell, but also do not need to pin a special crimping. However, the single board surface mount components, select the table paste the power connector is still more cost-effective decision. Aspects of wiring, screw connection, welding and winding must be hand-assembly, grind then and IDC can use an assembly of equipment on the market for quick, accurate assembly of the connectors and cables. IDC access and grind By contrast, IDC cable size requirements more stringent, cable conductor, the size and hardness of the insulation shall comply with the specifications of IDC Connectors, so as not to damage the connector and to ensure that cables and connectors the desired electrical connection.
