CROSS-REFERENCE TO RELATED APPLICATIONS AND PRIORITY
The present application does not claim priority from any other patent application.
TECHNICAL FIELD
The present disclosure relates to DC-DC converters, more particularly, the present subject matter relates to connector cap configured to mechanically and electrically isolate a terminal of the DC-DC convertor.
BACKGROUND
DC-DC conversion systems are required for efficiently producing a regulated voltage from a source that may or may not be well controlled to a load that may or may not be constant. Further, DC-DC converters are high-frequency power conversion circuits that use high-frequency switching and inductors, transformers, and capacitors to smooth out switching noise into regulated DC voltages. Closed feedback loops maintain constant voltage output even when changing input voltages and output currents. At 90% efficiency, they are generally much more efficient and smaller than linear regulators. Their disadvantages are noise and complexity. This DC-DC conversion is important for efficient working of battery system and therefore efficient working of all the battery-operated equipment.
However, working and efficiency of DC-DC converter depends primarily on how different parts are assembled. Another problem with DC-DC converters is that from safety point of view. DC-DC converter contains plurality of parts such as input connector, output connectors, fluid inlet and outlet and other metallic and electronic parts. However, when we are assembling the various parts there is problem of contact or touching the other ports. Which can cause short circuits and can be dangerous for the user and can further cause fire.
Therefore, a device that is equipped to isolate the output connector from rest of the parts is highly desirable.
Thus, there is long felt need for an output connector cap with terminal which can isolate the output connector from rest of surface parts assembled on the DC-DC converter.
