Key points for selecting high current D-sub connector.

1. Current requirements.

First, we must understand High current D-sub connector The carrying current and voltage of the contact shall meet the performance requirements.Connector The current load capacity of the is usually determined by the size of the wire and the contact, and the rated voltage is determined by the contact spacing and insulating material. Therefore, it must be ensured that the contact conforms to the size of the supporting conductor to avoid overheating.

2. Data sheet.

Understand connector manufacturers How to specify the rated current and operating voltage of its products is very important. The test level and data can refer to the manufacturer's standards, but the test standards used by different manufacturers are very different. Therefore, when viewing the current rating, first observe the temperature rise specification of the connector. This surface is the heat dissipation value of the high current D-sub connector under a specific current value.

3. Termination type.

Due to the many termination types of connectors, the use of welded contacts helps to prevent the entry of dust and moisture. The other is crimping, which is convenient for on-site maintenance, such as compression terminal, winding connection, direct connection, loop connection, eye connection, etc. In addition, the type of termination of the required connector depends on the size, type and voltage and current of the cable.

4. Mechanical and environmental performance.

Because the service condition of the connector is affected by a variety of application environments such as moisture, temperature, vibration and impact, it is in Select high current D-sub connector It is necessary to be very careful when designing the high current D-sub connector, clarify the mechanical, environmental performance and housing type, ensure reliable connection performance and avoid the influence of adverse factors such as short circuit.

5. Cost status.

because High current D-sub connector The price of is mainly determined by the hardware itself and the manpower and materials for assembly and maintenance. Therefore, do not covet small and cheap. The choice of cheap high current D-sub connector must be determined according to many aspects such as cost.
