The invention relates to a connector module. The connector module comprises a switching connector and two end portion connectors, each connector is provided with a high-speed differential zone and a low-speed zone, the high-speed differential zones of end portion connectors are provided with end portion differential units, the high-speed differential zone of the switching connector is provided with a switching differential module, each of the end portion differential units and the switching differential unit comprises a signal contact piece and a grounding shielding piece, the insertion portions, being in insertion cooperation with the switching connector, of the two end portion connectors are the same in structure, one of the end portion differential units and the switching differential unit is a male end unit, and the other one thereof is a correspondingly inserted female unit. The insertion portions, being in insertion cooperation with the switching connector, of the two end portionconnectors are the same in structure, when the end portion connectors are inserted into the switching connector, blind insertion operation can be directly performed with no need for identification, and therefore, the operation is more convenient.
