Abstract

The present invention relates to a box which is used in field and is used for installing cable joint of electrical power system or electrical equipment, wherein the box comprises a box body, an inner rubber cover, a throat fixer and an outer cover. The box provided by the invention can resist crushing and cutting. Furthermore a special structure neatly uses a principle of atmospheric pressure so that the closeness can be kept for a long time. Because the main supporting force of cover body comes from the cement floor, the cover body can bear a large pressure. Even when the cover body is damaged, the box is not damaged because of the cushioning of inner rubber cover. The repairing and maintenance are easy.

Description

1. Technical field: [0001] The invention relates to a box used in the field for installing and protecting cable joints or electrical equipment in a power system. 2. Background technology: [0002] The cover and the box of the currently used electrical box are generally fastened together by six screws, so that the cover and the box form a whole, so that when the box is rolled by mechanical equipment such as road rollers and lawn mowers, the box will If it is damaged, not only the cover but also the box are often damaged, which is not easy to repair, and after a long time, the contact surface between the cover and the box will rust and rot, lose airtightness, easy to enter water, and damage the electrical performance of the built-in equipment. 3. Contents of the invention: [0003] In order to overcome the deficiencies of the existing electrical box, the present invention provides a box body that is anti-rolling and anti-cutting, and the special structure enables it to maint...
