Under pressure, the joint of cable is difficult to close, certain apertured presence, water inlet phenomenon all occurs at 70% cable connector,
Influenceed by high-pressure steam, by the cable core and conductor of cable, into inside cable；What is entered when at the beginning is that water steams
Gas, water is reformed into after cooling, general floodable length is up to 80 meters or so, and temperature more hyperbar is bigger, and floodable length is longer；Water
After entering in cable conductor, it can make conductor that oxidation blackening occur, increase conductor resistance, insulaion resistance is remarkably decreased 50%,
Although cable manufacture finishes, detection insulaion resistance is relatively low, undesirable, it is necessary to re-work, and causes time-consuming expense
Power, cost of manufacture is added, while also hidden danger has been buried in the safe handling to cable.In consideration of it, the utility model provides one kind
Plastic-sheathed Cable water joint.
Utility model content
To solve the above problems, the utility model provides a kind of Plastic-sheathed Cable water joint, it can effectively avoid vapor
Cable connector is penetrated into, plays effective waterproof action.
The utility model is achieved through the following technical solutions：
A kind of Plastic-sheathed Cable water joint, including joint body, one end of the joint body is connected to draught line, another
End is connected to cable core, and the draught line is provided with the first connection end, and the cable core is provided with second connection end, and it is special
Sign is：The joint body includes multiple connection rings, and the multiple connection ring is concatenated into iron chains, and one end of the iron chains is fixed
The first connection end is connected to, the other end is fixedly connected on second connection end, and one layer of rubber layer, the rubber are coated with the iron chains
The both ends of layer are also respectively fixedly connected with draught line and cable core.
As a kind of perferred technical scheme, the external diameter of the joint body is equal to the external diameter of the cable core.
As a kind of perferred technical scheme, the connection ring is provided with five, including three big ring and two small rings, institute
State big ring and small central spacer is set.
As a kind of perferred technical scheme, first connection end and second connection end and the junction of the iron chains are equal
Tightened by copper wire.
As a kind of perferred technical scheme, first connection end and second connection end and the junction of the iron chains are equal
It is enclosed with rubber lamella.
As a kind of perferred technical scheme, it is enclosed with one layer of electrical adhesive tape outside the rubber lamella.
Beneficial effect：
The utility model because iron chains is solid, and is to connect with one another closely by real new iron chains outer cladding rubber layer,
Easily connection and bending, after being vulcanized by curing tube, in the state of HTHP, rubber layer is tightly coated on iron chains,
The solid entirety of a closing is formed, vapor is blocked from entering cable core, and play prevents Plastic-sheathed Cable end completely
The effect of head water inlet, water inlet rate are changed into zero by original 70 percent, substantially increase production efficiency.

Embodiment
Further to carry out open explanation to the technical solution of the utility model, below in conjunction with the accompanying drawings to a kind of Plastic-sheathed Cable
Water joint carries out clear, complete explanation.
It should be noted that in this specification it is cited such as " on ", " interior ", " in ", the use of "left", "right" and " one "
Language, be merely convenient to narration understand, and be not used to limit the enforceable scope of the utility model, the change of its relativeness or
Adjustment, in the case where changing technology contents without essence, when being also considered as the enforceable category of the utility model, conjunction is first chatted bright.
Accompanying drawing 1 is refer to, the utility model provides a kind of Plastic-sheathed Cable water joint, including joint body, the joint
One end of body is connected to draught line 1, and the other end is connected to cable core 6, and the draught line 1 is provided with the first connection end 2, institute
State cable core 6 and be provided with second connection end 5, the joint body includes multiple connection rings, and the multiple connection ring is concatenated into
Iron chains 4, one end of the iron chains 4 are fixedly connected on the first connection end 2, and the other end is fixedly connected on second connection end 5, the iron
