Detailed Description

The following describes a specific embodiment of the present invention with reference to the drawings.

Fig. 1 shows the basic structure of the passage storage box 1, which is in a bar shape and comprises a back plate 10 and a pair of side plates 11, wherein three plates form a containing space, an external cable 33 of a low-voltage switch cabinet 30 can be stored in the containing space, in addition, the passage storage box 1 also comprises a detachable panel 12, as shown in fig. 2, the panel 12 is the same as the back plate 10 in size and shape, and the back plate 10, the panel 12 and the side plates 11 can form a quadrangular structure with two open ends. A cable opening 101 is provided in the back panel 10, the cable opening 101 is located opposite to the external cable outlet 32 on the cabinet body 31 of the low-voltage switch cabinet 30, the external cable 33 extends from the cabinet body 31 and immediately enters the accommodating space, and in other alternatives, the external cable 33 can enter the accommodating space through the bottom opening of the access storage box 1, so that the structure of the back panel 10 can be further simplified, but the external cable 33 adjacent to the cabinet body 31 is not protected by the access storage box 1.

Inside the passageway storage box 1, three fixed rails 20 are arranged from top to bottom, one of which is located in the middle and two of which are located near both ends, and the fixed rails 20 are fixed on the back plate 10. In this embodiment, each fixed rail 20 is provided with three cable clamps 21, which correspond to three external cables 33 on the low-voltage switch cabinet 30, and in the actual application process, the number of the cable clamps 21 on each fixed rail 20 is correspondingly different corresponding to the number of the different external cables 33.

The height of the aisle storage box 1 is determined according to the length of the external cable 33, but does not exceed the height of the low-voltage switch cabinet 30, so that the low-voltage switch cabinet 30 is convenient to package and transport.

Fig. 3 shows another embodiment of the present invention, a low voltage switch cabinet 30 having the above described aisle storage box 1, comprising a box 31 and a switching device installed in the box 31, the box 31 having cable outlets on a side wall near the bottom, and three external cables 33 passing through the box 31 to the outside through the cable outlets. The channel storage box 1 is fixed on the box body 31, a cable opening 101 on the channel storage box 1 is in butt joint with the cable outlet, and an external cable 33 directly enters the channel storage box 1 through the cable opening 101 after coming out from the cable outlet and is sequentially fixed by three cable clamps 21 clamped on three different fixed rails 20 from bottom to top. In fig. 3, in order to show the cables inside the aisle storage box 1, no panel 12 is added, and in the actual product, the external cables 33 are closed by the detachable panel 12 after being fixed.

Not shown in fig. 3, each external cable 33 is labeled to facilitate a clear distinction between the individual cables when installed on site by an engineer, without the possibility of misidentification resulting in faulty operation.
