Description

Safe joint junction box

Technical Field

The application relates to the technical field of junction boxes, in particular to a safe combined junction box.

Background

The combined junction box is a secondary wiring connecting part of the metering device and is arranged in a metal metering box or a metal metering cabinet. Because the combined junction box normally operates in a hot-line mode, inspection and maintenance are always carried out in a hot-line mode, and faults are easy to occur.

At present, the existing combined junction box has the defects that the safe distance between a wiring hole and the wiring hole is insufficient (about 0.3 CM), and the distance between the wiring hole and a metal box body is insufficient (about 0.5 CM), so that the wiring of an adjacent hole is touched by mistake in live-line maintenance easily, and the secondary fault is caused when the metal box body is touched or the wiring of the adjacent hole is touched after a lead is blown easily.

SUMMERY OF THE UTILITY MODEL

The embodiment of the application provides a safe combined junction box, which effectively prevents the false touch of adjacent hole wiring in the live-line maintenance, and avoids the secondary fault caused by the touch of a metal box body or the adjacent hole wiring after the lead is blown.

In view of the above, the present application provides a safety joint junction box, including: the junction box comprises a box body and a plurality of binding posts, and the binding posts are fixedly arranged inside the box body.

And a plurality of wiring holes corresponding to the wiring terminals are formed in two sides of the box body.

The spacer includes first spacing piece and second spacing piece, first spacing piece longitudinal separation sets up the wiring hole left and right sides, the second spacing piece transversely sets up the lower surface of first spacing piece, and with first spacing piece fixed connection.

And a wiring screw for fixing is arranged on the wiring terminal.

The wiring screw is connected with the wiring terminal through threads.

And connecting sheets are arranged between the binding posts, and two ends of each connecting sheet are fixed on different binding posts through the wiring screws respectively.

And a junction box cover plate is arranged at the top of the junction box.

According to the technical scheme, the embodiment of the application has the following advantages: simple structure through set up the separator on the terminal box, has avoided electrified maintenance in-process mistake to bump adjacent wiring, makes it be difficult to cause touching metal box or adjacent hole wiring after the lead wire blows and sends secondary fault.
