Description
Technical field
The utility model relates to a kind of cable fitting that is used for the cable connection by casing protection, particularly a kind of low-voltage cable multiple-limb joint.
Technical background
At present, the low-voltage cable branch joint is general to adopt placing or injection molding technology at the scene with the cable strip off of major loop, draws a permanent duplexure on main loop cabling, the mounting process complexity, waste time and energy, joint quality is subjected to mounting material and technogenic influence very big, and reliability is low, and cost is higher, duplexure can not be dismantled or reinstall, and can only draw a branch at a point, can not realize that multiple-limb connects at a point.
Summary of the invention
It is a kind of simple in structure that technical problem to be solved in the utility model is to provide, and can realize that multiple-limb connects, and fitting operation is simple, reliability height, low-voltage cable multiple-limb joint with low cost.
The utility model is realized by following approach.
Low-voltage cable multiple-limb joint, its structural feature is: comprise conductive bus bar and insulation busbar overcoat, conductive bus bar is coated in the insulation busbar overcoat, and the insulation busbar puts outward and is distributed with a plurality of cable inlets.
Like this, the power cable of the strip off cable inlet by insulation busbar overcoat is inserted in the insulation busbar overcoat contact with conductive bus bar, cable of each cable inlet grafting, by conductive bus bar with each cable parallel connection, thereby form a plurality of branches, fitting operation is simple, fast and easy; And, can select to have the multiple-limb joint of the cable inlet of varying number during use as required and realize that multiple branches connects; And conductive bus bar is coated in the insulation busbar overcoat, from and reach insulated enclosure effect, reliability height.
Structure of the present utility model can be specially:
For cable conductor can firmly be contacted with conductive bus bar, cable conductor and conductive bus bar are fixed, below be wherein two kinds:
Low-voltage cable multiple-limb joint also comprises a plurality of cable conductor securing members, the insulation busbar puts outward and is distributed with a plurality of inlets that are fastenedly connected, the cable conductor securing member is installed in and is fastenedly connected in the inlet, and is connected with conductive bus bar, cable inlet be fastenedly connected inlet and connect.
This cable conductor securing member can be specially a kind of fastening bolt, during installation cable conductor is contacted with conductive bus bar from the cable inlet insertion, from being fastenedly connected inlet fastening bolt is tightened, thereby with firm being fixed on the conductive bus bar of cable conductor.
Perhaps, also can on the conductive bus bar at cable inlet place, process screw thread, conductive bus bar is connected with cable conductor by crimp type terminal.
When the securing member attached cable conductor, outside the insulation busbar, put and have the inlet that is fastenedly connected that securing member is installed, can all insulation, hermetically sealed for guaranteeing this multiple-limb joint, therefore:
Also comprise being fastenedly connected inlet seal lid, be fastenedly connected inlet seal and cover and be fastenedly connected on the inlet.
Simultaneously, being fastenedly connected the inlet seal lid is connected with insulation busbar overcoat by connecting frenulum.
Like this, will be fastenedly connected inlet seal, arbitrarily abandon after seal cover being taken off when preventing to install simultaneously, the seal cover and the busbar overcoat that insulate be linked together by connecting frenulum by being fastenedly connected inlet seal lid.
Ordinary circumstance can put outside the busbar in insulation and 3～10 cable inlets is set and is fastenedly connected inlet, thereby can select to have the multiple-limb joint of varying number as required.
Structure of the present utility model can further be specially:
The new low-voltage cable multiple-limb joint of this practicality also comprises cable adaptor, and the cable adaptor sleeve is in cable inlet, and cable adaptor is a kind of stepped body, and it inwardly successively decreases from the cable inlet place.
Like this, can be used to connect the cable of different size dimensions, make the cable of various models can both be applicable to this multiple-limb joint by this cable adaptor.When using this cable adaptor, when adapting to one section body of diameter minimum of this stepped adapter as cable dimension, just cable directly can be inserted on the adapter, and then adapter is inserted in the cable inlet place; When if cable dimension adapts to the bigger one section body of diameter, just the less body in this section body back is cut off, thereby cable just can insert in this adapter, thereby makes this multiple-limb joint not only can be applicable to various model cables, and can reach full-insulated full-sealed.
Cable adaptor has four layers of ladder.
The inside of cable adaptor body is distributed with a plurality of annular projections.Simultaneously, the endoporus at cable inlet has a plurality of annular projections.
Like this, thus cable inserts enhanced leaktightness effect in the cable adaptor.Cable adaptor is inserted in the cable inlet and is also played the enhanced leaktightness effect.
Cable adaptor also comprises seal cover, and seal cover covers the big end in cable adaptor.
Like this, can reserve duplexure, the loop of reservation seals by cable adaptor, thereby makes this multiple-limb joint full-insulated full-sealed.
Seal cover connects by being connected frenulum with the cable adaptor body.
Like this, can prevent from arbitrarily to be abandoned after seal cover from taking off and lose.
In sum, the utility model has the following advantages compared to existing technology: this low-voltage cable multiple-limb joint has simple in structure, can realize that multiple-limb connects, and fitting operation is easy, reliability height, characteristics with low cost.
