Detailed Description

The following embodiments are only intended to illustrate the present invention in detail, and do not limit the scope of the present invention in any way.

Example 1: a wiring-free closed type construction site distribution box is used for power distribution and single equipment in a construction site, and a wire outlet end is connected with a tertiary box, a fixed switch box and a special switch box, and is shown in figures 1 and 2. This block terminal includes the box and fixes landing leg 6 under the box, and the box is the cuboid, and the case is long 1100mm, and height 1200mm, thick 250mm adopts the thick galvanized steel sheet preparation of 1.5 mm.

The box body adopts a structure of a double-layer box door and a four-layer structure, and comprises an outer box door 1, an inner box door 2, an electrical element installation layer 3 and a box body back plate from front to back. The outer box door 1 is a double-door, and is made of a push type door lock and a whole steel plate. The inner box door 2 is also a double-opening door, adopts a triangular core hole lock, and can be opened on one side unlike the outer box door 1. Inner box door 2 opens a hole on whole steel sheet, exposes switch, test button and the components and parts parameter of electric elements installation layer, isolated electrical components and the electrified part of electric wire, can have effectively to prevent nonprofessional personnel's maloperation.

The electric element installation layer 3 is installed the electric element bottom on the epoxy insulation board, fixes to the metal electrical apparatus mounting panel again, then wholly fastens on the backplate of block terminal, and the box backplate adopts monoblock steel sheet preparation. The rear back plate is of a separated structure and is not directly mounted on the rear back plate, so that safety is guaranteed, and mounting, manufacturing and later maintenance are facilitated.
