Abstract
The utility model relates to a cable branch connector, comprising a main cable, a branch cable, a connection component, an insulation and isolation sheath of the branch cable and an insulation protection external tube. The main cable and the branch cable are bank cable, also can be single-core cable. The main cable branches out the branch cable at the client end, after being fixedly connected with the inner core of each phase of the main cable by the connection component, the inner core of each phase of the branch cable is phase-splitting isolated by the insulation and isolation sheath of the branch cable at the periphery of each connection component, and the periphery of the main cable, the branch cable, the insulation and isolation sheath of the branch cable after isolated are injection molded to an insulation protection external tube by the ambroin. The cable branch connector of the utility model has the characters of fire and water resistance, high voltage resistance, high insulation resistance, good safety performance, positive quality etc., which can be widely used in the system of branching, power distribution and alarm of multistory building.
Description
1, technical field
The utility model relates to the transmission of a kind of supply line or distributes the cable of electric energy, good, the reliable quality cable branch joint of specifically a kind of security performance.
2, technical background
Existing as to provide the cable of electric line transmission mostly to be common cable, enclosed busbar groove, common cable branch difficulty, leader cable carries out manual the connection at the construction field (site) with branch cable, operating process is very loaded down with trivial details, and the time is long, very easily causes the waste of cable and the confusion of circuit, and the quality of connection also can't guarantee, the electric connecting point of enclosed busbar groove is difficult to ensure the quality of products, and price is also very high.Development along with society; now also there are many cables of branch of being with to occur, but unreasonable on structural design mostly, there is not insulation protection with regard to direct fit injection moulding insulation protection overcoat at tie point; make the qualification rate of cable reduce; life-span is not long, has hidden danger, the protection of having carried out insulating material between tie point and each conductor that has; but he is an integrated operation between connector and each conductor; operation is long, and it is more loaded down with trivial details to operate, and cost is also than higher thereupon.
3, summary of the invention
The purpose of this utility model be provide at the deficiencies in the prior art a kind of fire-resistant waterproof, high pressure resistant, insulation resistance is big, security performance good, reliable in quality and cable branch joint rational in infrastructure.
The technical scheme that its technical problem that solves the utility model adopts is: cable branch joint is by leader cable; branch cable; connect fastener; branch cable insulated isolated jacket and insulation protection overcoat are formed; leader cable and branch cable are multicore cable; can also be single-core cable; leader cable is told branch cable in client; branch cable is the branch cable insulated isolated jacket is set forms last leader cable after isolation connecting the fastener outside again by connecting conductor that fastener connects another root cable respectively on the conductor on one or the one group of leader cable; branch cable; be injection molded into the insulation protection overcoat with ambroin around the branch cable insulated isolated jacket.
The connection fastener of prefabricated branch cable and other annexes all are prefabricated components, and each operation all is in slave mode, are convenient to retrieval, and steady quality is reliable.
Product is an integral construction and do not need field fabrication to be connected work such as fastener or branch cable insulated isolated jacket, saving personnel and shortened the time.
Big, the withstand voltage height of insulation resistance, security performance is good, volume is little, reduce the installing site area.
Can be according to the architectural design drawing, design the cross section specification and the collocation thereof of main cable and branch cable according to customer requirements, the position distribution of branch cable, parameters such as trunk and branch cable length can be prepared burden, effectively economical with materials accurately by norm.
4, description of drawings
Accompanying drawing 1 is the main TV structure profile of cable branch joint;
Accompanying drawing 2 is the left TV structure schematic diagram of cable branch joint.
5, execution mode
Explain with reference to Figure of description 1 with below 2 pairs of the utility model works of accompanying drawing.
Cable branch joint of the present utility model; be by leader cable 1; branch cable 2; connect fastener 3; branch cable insulated isolated jacket 5 and insulation protection overcoat 4 are formed; leader cable 1 and branch cable 2 are multicore cable; can also be single-core cable; leader cable 1 is told branch cable 2 in client; each phase inner core of branch cable 2 by connect fastener 3 and leader cable 1 each mutually the fixedly connected back of inner core each connect fastener 3 peripheries divide with branch cable insulated isolated jacket 5 isolated, the leader cable 1 after isolation; branch cable 2; be injection molded into insulation protection overcoat 4 with ambroin around the branch cable insulated isolated jacket 5.
Cable branch joint of the present utility model has fire-resistant waterproof, high pressure resistant, characteristics such as insulation resistance is big, security performance good, reliable in quality, can be widely used in the system such as separated time, distribution, warning of tier building, thereby have the excellent popularization using value.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
