摘要： Disclosed in the present invention is a threading sealing box, relating to the technical field of cable joints. The threading sealing box comprises a box body and a threading assembly, wherein an opening is formed in the box body, a mounting groove is formed in a side wall of the box body, the threading assembly comprises a threading plate assembly and a threading body, the threading plate assembly is slidably arranged in the mounting groove so as to slide into or slide out of the mounting groove, a penetrating hole is formed in the threading plate assembly, the threading body is arranged on the threading plate assembly, and the threading body communicates with the penetrating hole. A cable penetrating through the threading body can be circumferentially sealed by the threading body, thereby effectively reducing the water leakage risk; the cable does not need to be locked by using accessories such as a waterproof terminal, such that the operation is simple; an installation space is small, and more cables can be installed in the same space, thereby effectively reducing the cable wiring cost; and the cable can be taken out without being lifted by a machine, and therefore carrying operations are reduced, and the labor cost is saved.

摘要： The present invention relates to the technical field of electrical technologies, and in particular to electrical equipment. The electrical equipment provided by the present invention comprises a box body, a device, and a sealing member having both an electromagnetic shielding function and a sealing function. The device is detachably fixed on the box body, the sealing member is disposed between the box body and the device, and the base surface of the device can be attached to the installation surface of the box body, such that the sealing member can ensure the sealing installation of the box body and the device, and can also enable the base surface of the device to be closely attached to the installation surface of the box body to ensure the electromagnetic shielding function of conductive contact between the box body and the device. In the case of ensuring the sealing performance by using the sealing member, the electrical equipment does not need to add additional conductive contact parts between the box body and the device to ensure the electromagnetic shielding function of the conductive contact between the box body and the device, thereby reducing the process difficulty, saving cost, causing no short circuit inside the box body, and ensuring the stable operation of the electrical equipment.
