Description
Technical field
In the present invention relates to, low-voltage electrical cable branch field of accessories, particularly to one exempt to block speediness embranchment device and
Implementation method, is suitable for carrying out mineral insulated cable at the construction field (site) the application of branch's installation, solves conventional mineral insulation
When cable uses mineral cable T to meet feeder pillar branch, in its case, there is the problem that multiple cable point of cut-off is brought, to eliminate event
Barrier hidden danger.
Background technology
In, in the laying installation work progress of low-voltage electrical cable, mineral cable T is generally used to connect case to realize mineral
Insulated cable branch, mineral cable T connects the potential faults that feeder pillar is brought.
1, mineral cable T connects and includes binding post inside feeder pillar, and during installation, main cable to be blocked, passes through binding post
, owing to there being multiple cable point of cut-off, thus there is the potential faults producing fault in switching branch cable.
The conductive material of the binding post that existing arm product is used, usually cast iron reverse mould, then through surface finish
Process, finally process zinc-plated to metal surface.
Due to material reason, zinc-plated have bigger difficulty, and it is the most only simple readily plating that indivedual binding post surfaces process
Color.Here being important to illustrate, plating coloured silk is not the coat of metal, and plating coloured silk is only the silver after metal surface formation red copper is tin plating
Color bright coating illusion.Therefore so that the non-conductor material terminal that conductivity is very poor originally adds with cable conductors contact surface
Obstruct face, more reduces conductivity.It is more prone to produce Carbon Deposit Phenomenon, causes empty connection in using, and then cause power-off.
It addition, tightness only emphasized by this kind of binding post, but have ignored unlike material electric conductivity difference, meanwhile, non-conductor
Material is little with conductive cable contacts face, causes branch point overheated, there is electric disaster hidden-trouble.
2, penetrating cable clamp be also arm product one of,
At present, penetrating cable clamp most cities prohibit the use of.Penetrating cable clamp introduces French western kamu wire clamp the earliest
Technology, this technology explicitly points out as facing electricity application, and feature is that lower end electrical appliance power is little, and acupuncture point-like punctures cable jacket pair
Cable cover(ing) infringement is little.
When penetrating cable clamp is applied to cable branch, when differing greatly due to main cable cross section and branch cable cross section,
There is the biggest danger in the method.Because penetrating cable clamp is when the main cable that clamping cross section is bigger, do not clip to cross section less
Branch cable, tighten if continuing reinforcing, until clamping branch cable, but outside the heavy in section main cable clamped
Side, lifts owing to angle is big, and the very difficult range estimation of This move is discovered, and easily forms void connection.
It addition, in power supply-distribution system is applied, power cable is commonly YJV crosslinked cable, and cross-linked layer is positioned at cable conductor
And between cable cover(ing).This layer of crosslinking ratio is harder.Penetrating cable clamp acupuncture is short and thick, it is impossible to directly pierces through cable cross-linking layer, works as torsion
After square broken screw, operator takes for wire clamp and turns on cable.Even if wire clamp acupuncture turns on reluctantly with cable conductor, non-conductor
Material draw point Multi-contact face is less than terminal.Cause branch point overheated, there is electric disaster hidden-trouble and become apparent from.
Above-mentioned traditional mineral cable T connects feeder pillar internal structure and there is obvious defect, it is therefore desirable to designs and develops
The mineral cable arm product of a kind of new structure meets the needs of power supply and distribution of electric power system, and domestic there is no surmounts existing product
The novel mineral cable arm product of product structure general plotting occurs, how solving this problem just becomes art technology
The problem that personnel to study and to solve.
Summary of the invention
In view of situation and the deficiency of existence of prior art, the invention provides one and exempt to block water-proof type speediness embranchment device
Design, connection that assembly is combined is tied to use the contact assembly of inside and outside U-shaped conductor being suitable for cable shape to press with bolt
It is configured to the good contact to mineral cable, waterproof by body seal, by the surface contact structure of adaptor Yu interior U-shaped conductor
Form the good contact of the stub interface of main cable box branch cable.
Make every effort to the speediness embranchment device by being constituted with this construction features, overcome the defect of conventional mineral cable T joint feeder pillar,
Reach high-grade high temperature resistant, oil resistant, corrosion-resistant simultaneously, close, waterproof and moistureproof level, be widely used in power supply and distribution of electric power
