Single board assembly, device interconnection system, single board and fluid connector

The embodiment of the invention discloses a single board assembly, an equipment interconnection system, a single board and a fluid connector. Relates to the field of mechanical equipment, and solves the problem of poor reliability of a single board and a case. According to the specific scheme, the wrench comprises a body, an unlocking assembly and an elastic assembly. The unlocking assembly comprises a first unlocking part and a second unlocking part which are detachably connected, the first unlocking part is connected with the body, one end of the elastic assembly is elastically connected with the second unlocking part, and the other end of the elastic assembly is used for being elastically connected with a single plate; and when the first unlocking part and the second unlocking part are in a connected state, the elastic component applies a force to the second unlocking part to enable the second unlocking part to be far away from the first unlocking part. The problem that the electric connection male end and the electric connection female end are separated due to mutual repulsive force in the fluid connector can be effectively solved.
