Description

The cable splitter

Technical field

The utility model relates to a kind of cable branch unit that is applied to electrical power distribution system, relates in particular to a kind of cable splitter.

Background technology

The cable branch unit is widely used in electric power systems such as skyscraper, urban operating mechanism, bridge, tunnel.Traditional cable branch unit, the needs that have block main cable, and breakpoint multiple faults point is just many.Conducting position is directly exposed, has potential safety hazard (T connects case as cable).The volume that has is big, cost is high, installation is loaded down with trivial details, non-watertight, not dustproof, unshielded grade (as plug-board bus bar).The material that has is different with the cable material, unlike material temperature rise difference, and easily oxidation causes looseningly, and ampacity reduces, and can not satisfy the specification requirement (as penetrating cable clamp) of electric cable with large cross-section shunting.Although what have is identical with the cable material,, still can not satisfy big line footpath cable shunting (as the T connecting terminal) because the conducting position contact area is little.

Summary of the invention

In view of the various drawbacks that above-mentioned prior art exists, the utility model provides a kind of cable splitter especially, and this device is in addition perfect at volume, cost, material, all many-sides such as installation, particularly safety in utilization.

To achieve these goals, the technical scheme that the utility model is taked is: a kind of cable splitter, comprise the cable link that is enclosed in the shell, it is characterized in that: described cable link comprise base and with base be assembled into one about two loam cakes, described shell comprise be assembled into one about two shells.

The utility model can reach following beneficial effect: this installation cost is cheap, practical, simple installation, fundamentally solve and overcome existing technical barrier of Related product and defective.

Embodiment

Below in conjunction with accompanying drawing the utility model is elaborated:

Referring to accompanying

drawing

2,3,4,7, internal structure of the present utility model is the cable link, comprise base 1, upper left lid 2 and upper right lid 3, on base 1, be provided with ten concentric screw hole 101-110, about be provided with on two

loam cakes

2,3 respectively with base 1 on corresponding five concentric screw hole 201-205 of ten concentric screw hole 101-110 and 301-305, concentric holes 101～105 on the corresponding one by one base 1 of concentric screw hole 201～205 on the upper left lid 2, the concentric screw hole 106～110 on the corresponding one by one base 1 of the concentric screw hole 301～305 on the upper right lid 3.6 the holding screw 7 that is with insulating sleeve respectively by concentric screw hole 201-205,301-305 and the concentric screw hole 101-110 on the base 1 corresponding on the left and right

sides loam cake

2,3 with it after, it is fastening with clamp nut 9 to put insulation cushion 8 respectively, promptly finishes the assembling of base 1 and left and right

sides loam cake

2,3.

Because the irony holding screw all has insulating sleeve and insulation cushion, isolate fully with the conductive component of red copper material, promptly satisfied the intensity of parts, stopped again that heterotypic material contacts with conductive component and the potential safety hazard that produces.Insulating sleeve and insulation cushion all adopt fire-resistant, fire proofing.

Referring to Fig. 1,5,6,7, shell of the present utility model all adopts fire-resistant, fire proofing.Shell comprises left shell 4 and right casing 5, about be respectively equipped with concealed screw hole 401-404 and the 501-504 that is used to assemble on four angles of two shells 4,5, buckle closure screw 10 is assembled into one by concealed screw hole 401-404 and 501-504 with left and right sides shell 4,5 respectively.Be respectively equipped with the lead seal hole 405,505 that is used to prevent stealing in the upper end of left and right sides shell 4,5.Be respectively equipped with two concealed perforation screw hole 406-407 and 506-507 that are used for combination of monomers in the lower end of left and right sides shell 4,5.

Owing in the design of shell of the left and right sides, reserve lead seal hole, thereby satisfied the code requirement of power department to the product practicality.Owing to connect screw hole on the shell, monomer product can be made up.

Referring to Fig. 1,8, the utility model is bonded with the

semicircle sealing ring

11,12 that is used for waterproof and dustproof and corresponding cable external diameter respectively in two sides of left and right sides shell 4,5.The sealing ring of case member and outside diameter of cable coupling is closely as one, and with the conductive component sealing wherein, promptly safety reaches dustproof, waterproof requirement again.Self possess very high degree of protection, adapt to abominable installation environment.After product is installed,, after the encapsulation process, can directly expose outdoor or buried use with the fluid sealant sealing.

Base 1 of the present utility model and left and right

sides loam cake

2,3 all adopt the copper material identical with the cable material to make.Copper material comprises red copper or red metal, this device adopts the red copper identical with the cable material, red copper parts surface tining is handled, the crimping of encirclement formula, same temperature rise, contact area is big, in conjunction with the corresponding lap of splice, ensure the specification requirement of the amount of damming to greatest extent, realized that conductive component combines with the complete of cable.

The utility model volume is little, is example with the continued access of 300mm uiform section cable, and apparent size only is: long 100mm * wide 52mm * high 95mm.

This device can 360 ° rotation install, the randomness of branch cable any direction outlet is satisfied in more humane design, strengthens the product practicality more.
