Place the sealing substance in the space between described second external insulation element and the described interior insulation component.
In known junction box, the punched holes type coupling of conductive link separates with shell with each phase line of cable and the neutral line ， And that is fixed together respectively.But, repairing them needs a large amount of work, and they are also quite heavy.
The purpose of this invention is to provide the enough a spot of simple work of a kind of energy and be installed to junction box on the leader cable, can not touch the current-carrying part of this bindiny mechanism to guarantee the operator.In addition, this junction box is also compact and not too heavy.
Junction box of the present invention is characterised in that: each minute cable the end conductor and the extension of metal interlinking lever end with branch road bindiny mechanism of punching or coupling an integral body all placing the first external insulation element in, to each minute cable form an extention (appendix).
This junction box preferably satisfies in the following feature at least:
The described extension of the described first external insulation element protrudes from its side back to the second external insulation element when assembling;
This junction box further comprises the wedging insulating element of star section, these parts are slidably mounted in the cavity of the described extension of accepting described phase line or neutral conductor, drive screw by one and promote along cavity, with the conductor Wedge Pressure to the punched holes type coupling.
Interior insulation component is by embedding the concave type sliding connector to the plug-in type sliding connector and being connected with the described first external insulation element.
Punching coupling on the leader cable conductor comprise two be fixed on punched holes type coupling on described first insulation component and two be fixed on described in punched holes type couplings on the insulation component, by make described in the plug-in type coupling of insulation component enter in the concave type coupling of the described first external insulation element and make all 4 punched holes type couplings the insulating barrier punching on the respective conductors.
The first pair of conducting metal connecting rod that links to each other with first pair of conductor of one or two branch cable also directly links to each other with first pair of conductor of leader cable, and the plug-in type coupling by insulation component (9) in described and the concave type coupling of the first external insulation element enter another that make the second pair of conducting metal connecting rod conductor being linked to each other with another of one or two branch cable and leader cable mutually conductor is linked to each other.
As an example, describe that below in conjunction with accompanying drawing single minute cable is connected to low pressure and low power cablehead on the leader cable of 1KV, wherein:
Fig. 1 is the sectional view of this coupler assembly;
Fig. 2 illustrates slip and the wedging formula insulating element with the conductor punching of minute cable of being used for that has amplified.This figure is divided into two half sections on the plane perpendicular to Fig. 1 plane, its axis is II-II.First cross section is represented and the situation of dividing before cable conductor connects, the situation after following half section is represented to connect.
Among Fig. 1, junction box comprises two outer members that are called " housing ", and their ， And that is assembled together mutually are assembled on the inner member, and this inner member also is " housing ".The shell body 3 on top constitutes ， And by insulating material and is embossed in the metal shell that is made of external metallization coating layer 1.The shell body 14 of bottom also constitutes ， And by insulating material and is embossed in equally in the metal shell that is made of external metallization coating layer 2.Insulation inner housing 9 is placed in two cavitys between the shell body.Filling up nonconducting viscose glue sealed compound 4 in the surplus space of institute between top mold pressing shell body 3 and the insulation inner housing 9, for example vaseline.
The molded case body of upper and lower is that the periphery 20 of bumper shapes is worked in coordination by the cross section, makes sealing substance 4 compacted, and And prevents that water from immersing junction box.Assembling screw 27 and 28 is guaranteed that both are fastened to each other and is in the same place.
Leader cable comprises three-phase conductor 22,23 and 24, and a neutral conductor 25, is separated by an insulating barrier 26 between they are mutual.
Bottom insulation shell 14 comprise two be used for that leader cable conductor 23 is made of electric conducting material with two with 24 punched holes type coupling, be used for the concave type sliding connector 7A and the 7B that are connected with insulation inner housing 9.It also comprises several branch roads, discusses below in conjunction with the single sub-conductor that this example is considered.
The insulation inner housing has the phase conductor 22 that is used for leader cable and the punched holes type coupling 10 and 11 of the neutral line 25.They are connected with 12B with plug-in type sliding connector 12A respectively, and concave type sliding connector 7A and 7B on the shell body of plug-in type sliding connector 12A and 12B and bottom match.By means of this plug-in type coupling is assembled on the concave type coupling, inner housing 9 can be fixed on the shell body 14 of bottom.When the conductor wire core of the triple line of described assembly and leader cable and the neutral line contacted, their insulating barrier was just by punching.The insulation crust body 3 of upper and lower and 14 rigging screw 27 and 28 and the insulation of the coupling that is slidingly connected can not contact it with these charged phase lines.
These branch roads are constructed as follows: extension or extention 29 that insulation moulded body 14 has the cylindrical shape of being generally to protrude in the external metallization bump 13 of metal shell 2.This projection comprises four punched holes type coupling 15A, 15B, 15C and 15D.The first couple of coupling 15A and 15B exert pressure to the phase conductor 30A and the 30B of minute cable, and they link to each other with 6 with punched holes type coupling 5 with 31B by two conductive link 31A.In addition two coupling 15C and 15D link to each other with 7B with concave type sliding connector 7A with 31D by other two conductive link 31C to phase conductor 30C and the neutral line 30D ， And that exerts pressure.
In addition, cruciform shape slip insulating element 16 places between the conductor of branch cable, is used for the insulating layer of conductor punching on minute cable.(see figure 2) for this reason, these parts are suitable for pushing with driving screw 17.These parts also will divide the phase line of cable and the following half section that neutral line wedging punched holes type coupling 15A, 15B, 15C and 15D(see Fig. 2).At this moment, the tooth of these punched holes type couplings penetrates their conductor wire core with the insulating barrier ， And of feedthrough, has so just guaranteed and being electrically connected of minute cable.But, drive screw 17 and conductor electric insulation, so that can not come in contact between the phase line of operator and energising.
Obviously, a kind of like this junction box can be used for holding two branch cables, and they enter this junction box by respective end portions separately, and two branch cables terminate in two extentions 29 separately, their mutually symmetry, provide passage for separately driving screw 17.
