The application discloses a battery pack and an electric equipment. The battery pack comprises a lower box body, an upper box cover and a battery pack. The upper box cover and the lower box body are mutually covered to form a containing cavity. The upper box cover is provided with a liquid flow channel and a first through hole in communication with the liquid flow channel. The first through hole is located on a side of the upper box cover away from the lower box body. The first through hole is used for injecting liquid into the liquid flow channel. The battery pack is contained in the containing cavity. The battery pack is provided with an explosion-proof valve. The explosion-proof valve is arranged towards the first through hole. The upper box cover, the battery box body, the battery pack and the electric equipment provided by the application can improve the heat insulation capacity of the upper box cover, improve the heat insulation effect of the upper box cover, and thus improve the use safety of the battery pack.

The utility model discloses a kind of fireproof composite cables, belong to fireproof cable technical field, including composite cable outer layer and composite cable core, the inner wall of outer layer is fixedly covered with first fireproof layer, the inner wall of first fireproof layer is fixedly bonded with second fireproof layer, the inner wall of second fireproof layer is fixedly bonded with inner layer, and the core is covered in the inside of inner layer;The outer wall of outer layer is fixedly installed with mounting ring, the side of mounting ring is fixedly installed with controller, the side of mounting ring is fixedly installed with multiple springs and electromagnet;The outer wall of outer layer is slidably sleeved with hollow ring, the side of hollow ring close to mounting ring is fixedly connected with magnetic attraction ring, and magnetic attraction ring is attracted with multiple electromagnet;The end of multiple spring is extruded and slidably attached with the side wall of magnetic attraction ring.Compared with prior art, the device can effectively improve the fireproof effect of cable, and can extinguish the burning point of cable outer layer.
