detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

As shown in Figures 1 to 5, a new type of cable branch box is composed of a column 14, a rear door 12 and a front door 13. In the box of the branch box, an incoming copper bar 11 and an isolation knife are installed from top to bottom. Gate 1, confluence bus bar 2 and branch copper bar 3, zero line copper bar 7 and grounding copper bar 8 are arranged in parallel at the bottom of the box, the above-mentioned incoming line copper bar 11, isolation knife gate 1, confluence bus bar 2 and branch copper bar 3 are components placed in the box; the box is placed on a channel steel base 9, and it is characterized in that it also includes an inner door 5, which forms with the rear door 12 after the inner door 5 is closed. A space for accommodating the components; a molded case circuit breaker 4 is installed on the inner side of the inner door 5 , and an electromagnetic lock 6 is installed on the inner side of the inner door 5 close to the column 14 .

The isolating knife switch 1 has a handle 15 , and the handle 15 is fixedly mounted on the inner side of the inner door 5 through an extension rod 10 fixed on the isolating knife switch 1 and protruding toward the direction of the inner door 5 .

The coil of the electromagnetic lock 6 is powered from the incoming line copper bar 11 and the neutral line copper bar 7 .

The utility model comprises: an isolation knife switch 1 with an auxiliary contact, a confluence bus bar 2, a branch copper bar 3, a molded case circuit breaker 4, an inner door 5, an electromagnetic lock 6, a zero line copper bar 7, a grounding copper bar 8, a slot Steel base 9, extension rod 10, incoming copper bar 11, rear door 12, front door 13, column 14.

As shown in Figure 1, the handle 15 of the isolation switch 1 is installed on the inner door 5 through the extension rod 10, and the molded case circuit breaker 4 is installed close to the inner side of the inner door 5, and the corresponding position of the handle 15 on the inner door 5 is shown in Figure 3 Slotted for easy access.

As shown in Figure 4, the electromagnetic lock 6 is installed on the inner side of the inner door 5 close to the column 14, and the coil of the electromagnetic lock 6 is powered from the copper bar 11 of the incoming line and the copper bar 7 of the neutral line.

As shown in Figure 5, when the isolation knife switch 1 is closed, its long-closed auxiliary contact QS1 is opened, the coil Q0 of the electromagnetic lock 6 is de-energized, and the lock core 16 of the electromagnetic lock 6 pops up to ensure that the inner door is locked when the isolation knife switch 1 is closed. 5.
