Embodiment 1

[0011] In embodiment 1, such as figure 1 As shown, a grounding wire 3 is added at the bottom of the box body 5, and the grounding wire 3 is connected to the bottom of the rectangular box body of the distribution box to guide the static electricity on the distribution box to the ground for discharge in time.

Embodiment 2

[0012] Example 2, such as figure 2 As shown, because there are many charged wires at the bottom of the distribution box, in order to overcome the leakage of some wires, the current is reversely transmitted from the connected ground wire 3 to the rectangular box body 5 of the distribution box, resulting in the risk of electric shock. A diode 6 is added on the grounding line, and the positive end of the diode 6 is connected to the distribution box body. When the electrostatic charge is accumulated on the distribution box body 5, the diode 6 is turned on, and the electrostatic charge is conducted to the ground. The harm of static electricity to the human body is reduced; at the same time, the one-way channel performance of the diode 6 is used to prevent the reverse flow of the ground wire current to the top of the distribution box shell, and completely eliminate the electric shock accident caused by the electrification of the ground wire.

Abstract

The invention relates to a safety electrical distribution box. The safety electrical distribution box comprises a rectangular box body (5), wherein a tapered cover plate (2) is arranged on the rectangular box body (5); a through hole for a wire to pass through is formed in the lower surface of the rectangular box body (5) and an insulating cushion (4) is also arranged on the lower surface of the rectangular box body (5); the safety electrical distribution box is characterized in that a ground wire (3) is additionally arranged at the bottom of the rectangular box body (5), and the ground wire (3) is connected to the bottom of the rectangular box body (5) and used for immediately guiding static electricity on the distribution box into the ground for releasing. The safety electrical distribution box has the advantages that the current of the ground wire flows back to the housing of the distribution box by use of the one-way channel characteristic of a diode (6), and the electric shock accident caused by the charged ground wire is thoroughly eliminated.

Description

technical field [0001] The invention relates to an electric distribution box, in particular to a safe electric distribution box. Background technique [0002] The existing electrical distribution box includes a main body of the distribution box. The main body of the distribution box mainly includes a rectangular box body. The box body is provided with a tapered cover plate. An insulating pad is provided under the box body. The electrical distribution box of this structure is generally placed flat on the ground. Because there is an insulating pad underneath, it is easy to get static electricity on the distribution box. Once the human body accidentally touches the distribution box, a safety accident will occur. Contents of the invention [0003] The purpose of the present invention is to provide a safe electrical distribution box which can completely eliminate electric shock accidents caused by electrified ground wires. [0004] The technical solution adopted by the prese...
