Embodiment
Embodiment of the present utility model is further illustrated below in conjunction with accompanying drawing.
The internal structure of electrical junction box in the utility model one embodiment is represented see Fig. 2, Fig. 2.As shown in Figure 2, the electrical junction box for traction transformer comprises box body 1, end of incoming cables 2, leading-out terminal (3a, 3b, 3c), power cable (not shown) and control cables (not shown).Due to the very dense that power cable and control cables are arranged in electrical junction box, in order to see the internal structure of electrical junction box clearly, therefore eliminate power cable and control cables.Power cable and control cables are linked into box body 1 from end of incoming cables 2, pick out from leading-out terminal (3a, 3b, 3c) again, be provided with barricade (4a, 4b) in box body 1, power cable and control cables are isolated by barricade (4a, 4b).
Owing to being provided with the barricade (4a, 4b) for isolating power cable and control cables in box body 1, barricade (4a, 4b) can shield the electromagnetic interference of power cable to control cables, ensure that the Stability and veracity of control signal.Meanwhile, because barricade is arranged on the inside of box body, when not increasing box body volume, solving jamproof problem, ensure that electric terminal box structure is compact, do not affect the use of electrical junction box.
In the present embodiment, as shown in Figure 2, leading-out terminal (3a, 3b, 3c) has three, and one of them leading-out terminal 3a is positioned at the top of box body 1, and two leading-out terminals (3b, 3c) are positioned at a side of box body 1; Barricade (4a, 4b) has two pieces, and box body is divided into three regions by two pieces of barricades (4a, 4b), the corresponding leading-out terminal in each region.Due to the cable that the corresponding grafting of different leading-out terminals is different, different cables is isolated by two pieces of barricades (4a, 4b), plays shielding power cable to the effect of the interference of control cables.
In the present embodiment, as shown in Figure 2, corresponding with the leading-out terminal 3a at box body top in box body 1 is first area 11, and corresponding with the leading-out terminal 3b above a side of box body 1 is second area 12, and corresponding with the leading-out terminal 3c above a side of box body 1 is the 3rd region 13.Isolation first area 11 is the first barricade 4a with second area 12.Because the difference in height at the two ends of the first barricade 4a is larger, in order to not block leading-out terminal 3b, affect the connection of leading-out terminal 3b and cable, on first barricade 4a, bending forms a stage portion 4a1 for twice, the close one end of such first barricade 4a and leading-out terminal 3b can be arranged on the madial wall of the box body 1 above leading-out terminal 3b, does not affect the use of leading-out terminal 3b.The two ends of the first barricade 4a are connected with the madial wall of box body 1 by bolt 5.Isolation second area 12 and the 3rd region 13 are secondary shielding plate 4b.Because the difference in height at the two ends of secondary shielding plate 4b is less, therefore secondary shielding plate 4b is designed to S shape, and one end of secondary shielding plate 4b is arranged on the madial wall of the box body 1 between leading-out terminal 3b and leading-out terminal 3c.The two ends of secondary shielding plate 4b are also connected by the madial wall of bolt with box body 1.
Preferably, barricade (4a, 4b) can also pass through screw or welding or bond to be connected with the madial wall of box body 1.
Preferably, barricade (4a, 4b) is made up of magnesium alloy, and magnesium alloy has good electromagnetic shielding action.
Preferably, barricade (4a, 4b) is made up of almag.Almag has good toughness, easily bends, and is applicable to the inside being arranged on box body 1, can coordinate the installation site of end of incoming cables and leading-out terminal and the wire laying mode of power cable and control cables.
Electrical junction box in the utility model has the following advantages:
1, the interference of power cable to control signal can be shielded;
2, maintain compact conformation, save the advantage of installing space.
Above-described is only principle of the present utility model and preferred embodiment.It should be pointed out that for the person of ordinary skill of the art, on the basis of the utility model principle, other modification some can also be made, also should be considered as protection range of the present utility model.
