[0002] When the auxiliary switch cabinet circuit of the HXD1 series locomotive is remade, the 490 connector, as a kind of plug-in pin connector, also needs to be updated accordingly. During the production and inspection process of the 490 connector circuit, wrong insertion often occurs, resulting in damage to the pins. This often requires the wrongly inserted connector pins to be removed from the connector. In the absence of a special tool for removing the 490 connector pins, blindly withdrawing the pins will often cause the 490 connector to be damaged. Removing the pins is very cumbersome, which seriously affects the work efficiency of the switch cabinet circuit remaking and brings a lot of inconvenience to the operators. Therefore, a pin remover is provided to facilitate the detection of damaged pins. Utility Model Content
