Embodiment Construction
[0018] It consists of three phase deflectors, see figure 1 , each strip deflector is composed of a strip bottom plate 6, a main line pressure plate 1 and a branch line pressure plate 4, the strip bottom plate is concavely divided into three sections, and the two end sections are respectively the main line bottom plate 61 and the branch line bottom plate 63 , the middle section 62 sinks, and the effect of sinking is to accommodate the main line of other phase lines to pass through the sinking section, so that the top of the junction box is flat; On the sub-line base plate, the main and sub-line splints for clamping the main line and the sub-line are respectively formed. The conductor parts of the main line 3 of the phase line and the sub-line of the phase line 5 (that is, the insulation sleeve of the wire) are respectively embedded in the positioning grooves of the respective splints. , clamped by the fastening screws 2 of their respective splints, the main line is perpendicula...

The invention provides an intelligent power line distribution box insulation and fire prevention system of a building. The system aims to solve the problem that the junctions of branch lines are overheated and may cause a fire. The system is characterized by comprising three phase line bar-shaped current guide plates. Each bar-shaped current guide plate forms a main line clamping plate and a branch line clamping plate; the conductor parts of main lines and the conductor parts of branch lines are embedded into locating slots of the main line clamping plates and locating slots of the branch line clamping plates respectively and clamped by fastening screws of the main line clamping plates and fastening screws of the branch line clamping plates respectively, the main lines are perpendicular to the branch lines, and the direction of the branch lines is consistent with the length direction of bar-shaped bottom plates; the three phase line bar-shaped current guide plates are sequentially installed in the first row, the second row and the third row of a bottom box according to the length. The system further comprises a null line current guide plate. A main line clamping plate is arranged at one end of the null line current guide plate, three parallel branch line clamping plates are arranged at the other end of the null line current guide plate, and the conductor part of a main mull line and the conductor parts of branch null lines are embedded into a locating slot of the main line clamping plate and locating slots of the branch null lines respectively; the null line current guide plate is installed in the fourth row of the bottom box. The system has the advantages that the junctions will not be overheated, and therefore the fire is avoided; branch line operation is easy, and a branch line device is tidy in appearance.
Description
technical field [0001] The invention relates to a power line distribution box (device) for buildings. Background technique [0002] Before the main power line of the building enters the household, it is necessary to divide the line into each household. The usual connection method is at the tap point of the main power line, and each branch line is wound at each tap point. With use, the insulation properties of the wires decline or the wires are oxidized and poorly contacted. When a short circuit or load overload occurs, the wires will overheat and cause a fire. Contents of the invention [0003] In order to solve the above technical problems, the object of the present invention is to provide a building intelligent power line junction box insulation and fire prevention system. [0004] The object of the present invention is achieved in that it includes an insulating bottom box and an insulating box cover. It is composed of a sub-line pressing plate. The strip bottom plate...
