Heat Generation Of Cage-type Resistors With Pressed Insulation Layer Copper Terminal Blocks
Publish Time: Author: Site Editor Visit: 22
The cage-type resistor is stuck in the shell and presses the insulating layer copper terminal block to generate heat: when the conductor of the wiring enters the reed (bayonet), the reed (bayonet) presses part of the insulating layer of the wiring. Because the insulating layer copper distribution block has a certain thickness, the pressing force of the reed (bayonet) to press the wiring conductor is insufficient, the contact resistance increases, and when the current passes through for a long time, it is easy to cause abnormal heating and burning of the cage copper terminal strip.
