The cable joint, a press connecting terminal and a current conducting copper bar are full closed and full insulated, the insulation of a bus bar connecting board in the cable joint adopts a two-layer insulating structure, an inner layer is insulating rubber materials, and an outer layer is a semiconductive shielded layer. A wire input cable and a wire output cable of the cable joint can be completely separated, cable running is regular and beautiful, a partition board can be arranged between each input terminal and each output terminal, each input terminal and each output terminal are divided from space, and the utility model has the advantages that the crossed wiring probability of the cables of the input and the output terminals is reduced, safety hidden defect is relieved, and the operation of the utility model is convenient and safe.
Description
Technical field
The utility model relates to a kind of cable joint, especially relates to a kind of busbar fishplate bar turnover line and is in the not cable joint of ipsilateral, and it is applicable to cable branch box, switch cubicle, power transmission and distribution fields such as ring main unit.
Background technology
Present known cable joint two kinds of structures are as depicted in figs. 1 and 2 formed.In structure shown in Figure 1, can realize all insulation, hermetically sealed.But its busbar fishplate bar turnover line is in same direction, and when being connected with switch cubicle, operation is inconvenient, and cabling is not smooth.And structure shown in Figure 2, its busbar fishplate bar turnover line is at different directions, and easy to operate when being connected with switch cubicle, cabling is smooth and easy.But, its full skirt shape structure makes the end of incoming cables can not realize all insulation, hermetically sealed cooperation, the end of incoming cables exposes in air, by air insulation, dielectric strength according to air is calculated, the creepage distance of the 10KV level product of this structure should be greater than 250mm, the fold distance of cluster parachute in the calculating, its air line distance L at least also needs 170mm, the cable branch box that uses this structural cable joint to make is bulky, and water, filth, condensation etc. all can reduce insulation property, the possibility of creeping discharge is very big, can not waterproof, antifouling, anti-condensation.
Summary of the invention
In order to overcome the deficiency of existing cable joint, the utility model provides a kind of cable joint, and this cable joint can not only make the cable branch box internal wiring smooth and easy, easy to operate, and has characteristics such as waterproof, antifouling, anti-condensation, creepage distance be short.
According to the cable joint of first aspect present invention, form by end of incoming cables and leading-out terminal, it is characterized in that: corresponding end of incoming cables, a plurality of leading-out terminals that are electrically connected with it can be arranged, end of incoming cables and leading-out terminal are positioned at the two sides of cable joint.
Cable joint according to second aspect present invention is characterized in that: end of incoming cables and leading-out terminal all have T shape body and insulating plug, and with cable joint, crimp type terminal and conducting copper are totally-enclosed, all insulation.
Cable joint according to third aspect present invention is characterized in that: two-layer structure is adopted in the insulation of the busbar fishplate bar in the cable joint, and internal layer is an insulation compound, and skin is a semiconductive shielding layer.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
Fig. 3 is the structural representation of the utility model embodiment, and as shown in Figure 3, present embodiment is the structure of one-in-and-two-out, that is, and and 1 two leading-out terminals 2 in an end of incoming cables.Cable 41 enters from the end of incoming cables.Cable 4 enters in the T type body 10, the lead in the cable 14 in T shape body 10 with crimp type terminal 6 crimping, the crimp type terminal 6 behind the crimping lead is connected with conducting copper 3 with bolt 15 by packing ring 7, the formation conductive path.Cable joint shown in Fig. 3 has 2 leading-out terminals 2, has only shown the structure of one of them leading-out terminal 2 among the figure in detail, realizes branches from the electric current of the cable 4 by end of incoming cables 1 through conducting copper 3, forms the structure of one-in-and-two-out.Also can make one according to design of the present utility model advances three and goes out or one advance four and a structure of advancing to have more such as go out.The internal structure of leading-out terminal 2 is similar to end of incoming cables 1, in the outside of busbar fishplate bar 11 shield semiconductors layer 9 is arranged, and these screen 9 ground connection can realize that the electricity point touches, and guarantees user of service's safety.Internal layer is an insulation compound 8, is main insulating layer, and conducting copper 3 is isolated from the outside, and turnover line end 1,2 is all protected with T shape insulating sleeve, and its die cavity and cable 4 form between busbar fishplate bar 11 and the insulating plug 5 and closely cooperate.Realize all insulation, hermetically sealed, insulating plug 5 shutoff crimp type terminals 6 and be connected Luo bolt 15 are not affected by the external environment total, as rainwater, filth, condensation etc., and the assurance class of insulation; Owing to adopted full-insulated full-sealed structure, there is not creepage problem, therefore, corresponding air line distance L shown in Figure 2 gets final product greater than 90mm.Can save the feeder pillar body space greatly.
Fig. 4 is the circuit winding diagram of the cable joint of prior art, as shown in Figure 4, the cable that enters cable joint from switch 12 inserts three cable joint ends of incoming cables 1 shown in Figure 4 respectively, and the cable of drawing from 3 leading-out terminals 2 and enter cable the same side at cable branch box, seem mixed and disorderly, not attractive in appearance, neatly, simultaneously because be not easy to separately pass in and out cableport with dividing plate, even under the situation of (drawing back switch), the switch end of incoming cables is still charged, has potential safety hazard during maintenance so at one end cut off the power supply, and causing the stube cable cabling to have some setbacks, construction is inconvenient.
Fig. 5 is to use the circuit winding diagram of the utility model cable joint, as shown in Figure 5, cable joint is positioned at the two sides, thereby inlet wire cable and outlet cable can separate fully, and cabling is promptly neatly attractive in appearance again, and, a dividing plate can be installed between in-out end, end of incoming cables and leading-out terminal are separated from the space, reduce the cable improved cross connect probability of in-out end, removed potential safety hazard, it is easy and safe to operate.
