Description

RVB flat type connects shell-less flexible cord

Technical field

The utility model belongs to electrical equipment technical field, and specifically a kind of RVB flat type connects shell-less flexible cord.

Background technique

RVB flat type connects shell-less flexible cord with extensively, largely applies in power equipment.RVB flat type connects shell-less Flexible cord is mostly to carry out selling transport after the group of being rolled by single flexible cord, in use, the RVB flat type of length needed for intercepting connects nothing Sheath flexible cord carry out using.In use, RVB flat type connection shell-less cord ends needs are cutd open except external insulation, it is now mostly to be Using the ignition installations calcination insulating layer such as lighter, cutd open later from or being cutd open from insulating layer using thread cutter.Since insulating layer is mostly Polyvinyl chloride rubber is made, and calcination insulating layer can generate harmful substance, and fracture is coarse, cuts open length from insulating layer not It determines；It is cutd open using thread cutter and is easy to damage inner conductor from insulating layer.It is exhausted outside traditional method both threads beam cutd open from insulating layer Edge layer fracture distance is got too close to, and exposed conductor is not easy to carry out insulation processing in the root close to insulating layer fracture, is made for a long time Used time conductor is easy to cause accident in root short circuit.

Summary of the invention

Goal of the invention: the purpose of this utility model is to provide a kind of RVB flat type connection nothing for the deficiency in current technology Sheath flexible cord can quickly be cutd open from insulating layer, and fracture is smooth, cut open from insulating layer length it is controllable, cut open the conductor from after and be not easy Accidentally touching leads to short circuit.

Technical solution: to achieve the above object, the utility model provides a kind of RVB flat type connection shell-less flexible cord, including Two beam conductors, every beam conductor have been respectively coated by insulating layer outside, and the insulating layer is made of rubber, and two beam conductor external insulation layers are connected It connects, separating tank is provided on the insulating layer, the separating tank is equally distributed along axis on every beam conductor external insulation layer Annular trough body, the separating tank section configuration are semicircle, and separating tank is interspersed on two beam conductor external insulation layers.

As a kind of improvement of this programme, the conductor is that multicore annealing naked copper is twisted.

As a kind of improvement of this programme, the insulating layer is made of polyvinyl chloride.

As a kind of improvement of this programme, adjacent separation separation is 4-6cm on single beam conductor external insulation layer.

As a kind of improvement of this programme, separating tank is 5-10mm along axial minimum distance on two beam conductor external insulation layers.

The utility model has the advantages that a kind of RVB flat type described in the utility model connects shell-less flexible cord, separation is provided on insulating layer Slot, wall thickness is less than the wall thickness being not provided at separating tank at the separating tank, when the RVB flat type of interception appropriate length is connected without shield After covering flexible cord, overhang insulation layer is pullled, since wall thickness is relatively thin at separating tank, rear insulating layer is pullled and is disconnected from separating tank, fracture It is smooth.Separating tank is 5-10mm along axial minimum distance on two beam conductor external insulation layers, and two beam end conductor external insulations cut open From rear, there is the distance of 5-10mm between insulating layer fracture, two beam conductors respectively with connection, since insulating layer fracture is staggered, It can prevent from being difficult to the problem of carrying out insulation processing caused by being too close to due to insulating layer fracture.
