The cable docking mechanism is characterized in that a first water-resisting layer is arranged on the joint of the end portion of the connecting pipe and the end portions of the cable core insulating layers, and the joint of the two end portions of the intermediate joint and the semiconducting electric shielding layer of the cable is sealed by a second water-resisting layer. The docking mechanism has simple structure, convenient operation and excellent water resistance.
Description
Technical field
The utility model relates to a kind of electric cable accessories, is specially a kind of docking mechanism that is used for docking between cable.
Background technology
Known, the butt joint that will reliably finish between cable need be finished by cable butting mechanism, and before butt joint earlier to cable in accordance with regulations size carry out preliminary treatment, make cable end along its length in accordance with regulations size expose one section cable core, one section cable core insulating barrier, one section cable semi-conductive screen, one section cable copper shield, one section sheath, one section steel armour and oversheath successively.Cable butting mechanism comprises: tube connector, be set in two cable core joint outer peripheral faces, and finish the connection of cable core; Tubulose transition joint, coaxial package are in the outer peripheral face of tube connector and cable core insulating barrier, and both ends connect one section of two cable semi-conductive screens respectively; The copper mesh cover is wound in the transition joint outer peripheral face, and both ends connect one section of two cable copper shields respectively, and fixes by constant force spring; Intercoil connection is arranged along the cable axial direction, is connected with the steel armour of two sections cables, and fixes by constant force spring; Watertight composition has two-layerly, and ground floor is wound in copper mesh cover outer peripheral face, and both ends connect one section of two cable inner sheaths respectively, and the second layer is wound in the outer peripheral face of ground floor water blocking tape and intercoil connection, and both ends connect one section of two cable jackets respectively.
But above-mentioned docking mechanism can't be accomplished waterproof completely, if cable is certain part water inlet before butt joint or in the running, infiltrate inner as the watertight composition water that breaks, the aqueous vapor of cable just is easy to enter transition joint inside in running,, in reality,, cable causes the not within minority of cable line fault because intaking because thereby transition joint is climbed to wear and caused cable fault.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, easy to operate and cable butting mechanism that water resistance is good.
For this reason, the utility model is achieved by the following scheme:
A kind of cable butting mechanism is used to realize the butt joint between cable, comprises tube connector, is set in two cable core joint outer peripheral faces, and connects two cable core insulating barriers; The tubulose transition joint, coaxial package is in the outer peripheral face of tube connector and cable core insulating barrier, and both ends connect one section of two cable semi-conductive screens respectively, it is characterized in that: described tube connector end and junction, cable core insulating barrier end are provided with the ground floor water blocking layer, and described transition joint both ends and cable semi-conductive screen junction seal with second layer water blocking layer.
The thickness of described ground floor water blocking layer is no more than the thickness of cable core insulating barrier.
Described ground floor water blocking layer and second layer water blocking layer are that water blocking tape is Wrapping formed.
The utlity model has following beneficial effect:
The ground floor water blocking layer is the cable core water-proofing treatment, can effectively stop the water of cable core to enter transition joint, the second anti-layer water blocking layer is the water-proofing treatment of insulation shield layer, can effectively stop the water of insulation shield layer outside to enter transition joint, do this two-layer blocking water and handle the reliability that can effectively improve cable line.
Above-mentioned ground floor water blocking layer, second layer water blocking layer be simple in structure, it is very convenient to install, and only needs to twine water blocking tape and get final product in the different step that cable butting mechanism is installed.
