The utility model discloses a novel four-group relay module, and relates to the technical field of relays. The relay comprises a wiring terminal, a relay body, an injection molding shell, an integrated circuit board and a relay base. The relay is fixed in a clamping groove of the relay base, the relay base is in circuit connection with the integrated circuit board, the wiring terminal is connectedto the integrated circuit board and connected with the relay through the integrated circuit board and the relay base to form a control loop, the relay base is fixed in the injection molding shell, and an upper cover is connected to the injection molding shell. The two ends of each relay clamping groove in the relay base are hinged to anti-disengagement hooks. The anti-falling hook comprises a support, a hook body and a linkage rod. A hook is fixed at the upper end of the support, a linkage rod is fixed at the lower end of the support, and the support is hinged in grooves at two ends of the relay base. According to the utility model, the relay is automatically clamped, so that the relay is effectively prevented from falling off during normal use; and the anti-drop hook is small in stress,so that the connecting rod at the bottom is not easy to break off due to overlarge stress.
