The invention discloses a monitor equipment assembly, a monitor and a monitor module. The monitor equipment assembly comprises first monitoring equipment and second monitoring equipment, wherein the first monitoring equipment and the second monitoring equipment are in butt joint, the first monitoring equipment comprises a first outer shell and at least one connector arranged in the first outer shell, the connector comprises an elastic body and a conductive needle head which is supported by the elastic body and can move along the axis of the elastic body in a reciprocated mode, the conductive needle head is exposed out of the first outer shell, the second monitoring equipment comprises a second outer shell and at least one conductive terminal extending out of the second outer shell, and the conductive terminals correspond to the conductive needle heads of the connectors one to one. When the first monitoring equipment and the second monitoring equipment are butted in place, the conductive needle head contacts with the corresponding conductive terminal in an elastic mode under effects of the elastic body. Only a small part of the conductive needle head is exposed out of the first outer shell. The conductive needle head has certain elasticity, can lower probability of damage caused by collisions by external force, and improves reliability and compactness of the equipment.
