Abstract
A bayonet branch-protection-type branch cable is provided, pertaining to the cable technology, comprising a main cable, a branch cable and a connector sheath, characterized in that it includes a branch connector consisting of a fuse, a fuse cartridge and a 'C'-shape connector; one end of the fuse is connected to the branch cable, and the other end connected to the fuse cartridge; the fuse cartridge is connected to the main cable conductor; and the branch connector is encased by the connector sheath. The utility model has a simple structure and is easy to manufacture at a low cost. The branch cable is mounted with a fuse protector which protects against the overloading or the short circuit. It ensures the safety of people or property and more importantly, meet the need for power distribution protection on long-branch loops of 3m or above, thereby expanding the range of application for branch cables. The utility model is easy to connect or remove, and can be mounted onsite; it is convenient to scale up, maintain or repair; and it is valuable for spreading.
Description
Technical field
The utility model relates to a kind of structure of branch cable, belongs to the cable technology field.
Background technology
Branch cable is used over past ten years at home, is subjected to people's favor with its succinct practical tree type distribution system, the high performance-price ratio of economic and reliable, application property easy for installation, has obtained extensive use at architectural electric and other places.
But; present various distribution design specifications have all been made restriction to the cable branch of being longer than three meters as " low rule ", " people's rule ", " the high rule " etc.; this is because in this case; breaker protector on the main line is difficult to protect the branch cable behind the reducing, thereby has limited the range of application of branch cable.
The branch cable of tradition branch cable is crimped mould and is crimped on the main cable, and the mold insulation layer is as the sheath of branch's union body then.Branch cable and main cable become one, and are a kind of nonvolatil connection, and be non-dismountable.And if user's line loop is when needing dilatation under the power load condition of enlarged, traditional branch cable is difficult to realize.If short-circuit conditions and branch line is damaged also can't be changed.
The utility model content
The purpose of this utility model is the deficiency that exists at existing branch cable, provides a kind of branch cable is combined with protection component, is beneficial to branch line overload and plug-in type branch line protection type branch cable short-circuit protection and that be convenient to the branch line dilatation.
The purpose of this utility model is to realize by the improvement to existing branch cable; plug-in type branch line protection type branch cable; comprise main cable, branch cable and connector sheath; it is characterized in that being provided with branch's connector that fuse, fuse deck and C shape connector constitute; one end of fuse connects branch cable; the other end connects the fuse deck, and the fuse deck is connected with the main cable conductor, and branch's connector is wrapped in the connector sheath.
Described fuse deck is made by copper sheet material, and cross section equals the branch cable cross-sectional area of conductor at least, and an end is crossed the crimping of C shape connector with the main cable conductor dbus and is connected, and the other end is provided with and is used for the bayonet socket that is connected with fuse.
Bayonet socket place corresponding to the fuse deck on the described connector sheath is provided with the slotted eye of putting into for fuse.
Described branch connector is provided with the insulating material XLPE identical with main cable.
The material of described connector sheath is the injection grade injection molding material identical with the sheath material of main cable, branch cable.
The conductor of plug-in type branch line protection type branch cable adopts stranded the forming of copper single line that meets the GB/T3953 regulation, and conductor wire core meets the requirement of 2 class conductors among the GB/3956, has guaranteed that product has excellent conducting performance and pliability.Insulation uses XLPE as cable insulation material, has better dielectric strength and heat-resistant stability than PVC.Outer jacket adopts the pvc material extrusion molding, and the polyvinyl chloride anti-wear performance is good, and corrosion resistance is good, and softness is good, can protect the insulation of cable well.Sheath material also can be decided according to customer requirements, such as using the low smoke and zero halogen protective cover material, the rescue work when this helps protecting environment and fire to take place.Fuse is connected with the fuse deck, adopt clipping or the lock screw type fix.Fuse adopts the low pressure fast acting fuse of national Specification.
The utility model is simple and reasonable, manufactures easily, and cost is low.Protector has been installed on the branch cable, has been made product have the function of overload protection and short-circuit protection, can effectively protect user's personal safety as well as the property safety, the most important thing is to satisfy the needs of line loop power distribution protection of drawing money on credit more than the 3m, expanded the range of application of branch cable.Branch cable can be connected with the convenient installation of main cable and dismantle with protector, can carry out the scene and install, when the user needs dilatation, can replace with the required cross-section of cable as required easily, form the branch cable of another kind of combination, reach the purpose of dilatation; Secondly, when the protector of branch cable damages because of big electric current, can pull down easily, replace with another protector.
