Monitor device assembly, monitor and monitor module

The invention discloses a monitor device assembly, a monitor and a monitor module. The monitor device assembly comprises a first monitor device and a second monitor device which are in butt joint. The first monitor device comprises a first shell and at least one connector arranged inside the first shell. Each connector comprises an elastic body and a conductive pin head which is supported by the elastic body and can reciprocate in the axial direction of the elastic body. Each conductive pin head is exposed out of the first shell. The second monitor device comprises a second shell and at least one conductive terminal exposed out of the second shell. The conductive terminals correspond to the conductive pin heads of the connectors in a one-to-one mode. When the first monitor device and the second monitor device are in butt joint to be in place, the conductive pin heads are in elastic contact with the corresponding conductive terminals under the effects of the elastic bodies. Only small parts of the conductive pin heads are exposed out of the first shell, certain elasticity is achieved, the probability of damage caused by external force impacting can be reduced, and the reliability and the compactness of the device can be improved.
