Connector pin height detector

The utility model provides a connector pin height detector, which relates to the technical field of automobile switch assembly, and is characterized in that an ejector rod is arranged in a notch in a detection component with a U-shaped structure, and an elastic component is utilized to enable the ejector rod to have a trend of pressing a pin on a circuit board, so that the height of the pin affects the height position of the ejector rod, and the pin height is accurately detected. When the height of the pin is in a normal height state, light emitted by the optical fiber emitting part penetrates through the light-transmitting slotted hole to enter the optical fiber receiving part, the optical fiber receiving part normally receives an optical signal, a worker judges that the height of the pin is not abnormal according to the optical signal, and when the height of the pin is lost or lower than the normal height, the optical signal is transmitted to the optical fiber receiving part. The light emitted by the optica
