Referring to fig. 1-4, 1 is an ammeter box, 2 is an original copper bar branch box, 3 is an original wiring copper bar, 4 is a new copper bar branch box, 5 is a new wiring copper bar, 6 is a first connecting piece, 6-1 is a static contact piece, 6-2 is a supplementary arrangement, 7 is a second connecting piece, 7-1 is a movable contact piece, 8 is an insulating plate, 9 is a handle, and 10 is a bolt.
Detailed Description
The utility model is further described below with reference to the accompanying drawings.
Fig. 1 shows an arrangement structure of an original copper bar branch box 2 and an electric meter box 1 before transformation, wherein an original commercial power cable enters the original copper bar branch box 2 through a hidden wire and then enters the electric meter box 1 through the hidden wire after being branched. Because new electric equipment is needed, a new line is connected with a new electric meter from the original copper bar branch box 2, the original copper bar branch box 2 is not enough in arrangement, and the original copper bar branch box needs to be subjected to capacity expansion transformation.
The structure of the expansion transformation of the copper bar branch box is shown in fig. 2-4, a new copper bar branch box 4 is arranged below the original copper bar branch box 2 in parallel, a new wiring copper bar 5 is arranged in the new copper bar branch box 4, the lower part of the original copper bar branch box 2 is opened above the new copper bar branch box 4, the wiring bar below the original wiring copper bar 3 is fixedly connected with a first connecting piece 6, a static contact piece 6-1 is fixed below the first connecting piece 6, the static contact piece 6-1 is composed of two extending elastic contact pieces, the outer side of each elastic contact piece is opened outwards Zhang Kaicheng, the wiring bar above the new wiring copper bar 5 is fixedly connected with a second connecting piece 7, one side of the second connecting piece 7 is rotatably connected with a movable contact piece 7-1, one end of the movable contact piece 7-1 is connected with an insulating plate 8, and the insulating plate 8 is connected with a handle 9. The lower part of the original copper bar branch box 2 and the upper part of the new copper bar branch box 4 can be opened by an angle grinder, so that the inner spaces of the original copper bar branch box 2 and the new copper bar branch box 4 are communicated. The wiring bar below the original wiring copper bar 3 is fixedly connected with a first connecting piece 6 through a nut, and the first connecting piece 6 is fixedly provided with a static contact piece 6-1; the wiring row above the new wiring copper bar 5 is connected with a second connecting piece 7 through a nut, and the second connecting piece 7 is rotationally connected with a movable contact piece 7-1. The two extending elastic contact pieces of the static contact piece 6-1 are mutually clamped, the opening parts of the two elastic contact pieces are outwards bent to form an opening angle, the movable contact piece 7-1 rotates, the opening of the elastic contact piece cuts into the space between the two elastic contact pieces, the original wiring copper bar 3 is communicated with the new wiring copper bar 5, and the elastic contact pieces clamp the movable contact piece 7-1 to prevent the sliding of the copper bar. The insulating plate 8 is simultaneously connected with the movable contact pieces 7-1, and the movable contact pieces 7-1 can be simultaneously rotated by pulling the handle 9 to control the on-off of the new wiring copper bar 5. The cable branched by the new copper bar branch box 2 passes through the new copper bar branch box 2 and is connected with the external ammeter and then connected with the newly-added electric equipment.
The first connector 6 is provided with a complementary row 6-2. Because the first connecting piece 6 occupies the lowest row of the original wiring copper bar 3, the supplementary row 6-2 is used for replacing the wiring connected with the original row, so that the original wiring passage is not influenced by the on-off of the movable contact 7-1.
The upper part of the new copper bar branch box 4 is fixedly connected with the lower part of the original copper bar branch box 2 through bolts 10. Therefore, a new copper bar branch box 4 does not need to be punched and installed on the wall body, the wall body is prevented from being damaged, and noise is not generated to disturb people.
