Example Embodiment

[0011] In Example 1, such as figure 1 As shown, a grounding wire 3 is added to 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, and is used to introduce the static electricity on the distribution box to the ground in time for release.

Example Embodiment

[0012] Example 2, such as figure 2 As shown, because there are many live wires at the bottom of the distribution box, in order to overcome the current from the grounding wire 3 connected to the rectangular box body 5 of the distribution box when part of the wires leak, the present invention also A diode 6 is added to the grounding line. The positive terminal of the diode 6 is connected to the distribution box body. When electrostatic charges are accumulated on the distribution box body 5, the diode 6 is turned on and the electrostatic charges are conducted to the ground. It reduces the harm of static electricity to the human body; at the same time, the unidirectional channel performance of the diode 6 is used to prevent the ground current from flowing 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...
