Description
Technical field
The invention belongs to the manufacture craft fields of power cable connector, and in particular to a kind of system of three-core cable transition joint
Make method.
Background technique
Cable is very important component part in power supply system, the safety fortune of security relationship to entire power supply system
Row.On whole cable run, cable intermediate joint really weak link, in the cable fault occurred, cogging problem is led
The failure of cause accounts for very big specific gravity.China uses isolating shrinkable material and technical application in intermediate joint of electric cable at present
In production, cable core is attached in same position, since every core wire outer wrap adhesive waterproof tape and semi-conductive tape make
Joint area forms bigger protuberance, causes core wire to form biggish radian in joint area, simultaneously, it has not been convenient to install thermoplastic
Sealing sheath pipe.With the increase for using the time, such cable connector is easy to appear failure, causes bigger accident.Cause
This, the production method for proposing a kind of three-core cable transition joint is necessary to solve the above technical problems.
Summary of the invention
The present invention provides a kind of production method of three-core cable transition joint, to solve the shortcomings of the prior art.
The present invention is realized by following technical scheme:
A kind of production method of three-core cable transition joint, should be the production method is as follows:
Step 1: length and the determination of cable connector are determined according to length needed for single-phase cable connection (length of 5-6 in figure)
The length that cable end external sheath layer strips, wherein armouring fracture distance oversheath fracture length and armouring are apart from inner sheath fracture
Length required referring to previous technique；
Step 2: after stripping armouring, inner restrictive coating as requested, expose three cable cores of copper shield, keep an electricity
The length of cable core is constant, other cable core equidimensions successively truncate；
Step 3: stripping the copper shield, semi-conductive layer and insulating layer of the equal length of every cable core respectively, exposes phase
With the cable core of size；
Step 4: thermoplastic sealing sheath pipe is inserted in cable one end；
Step 5: as requested connecting every core of two cables, and wraps half conduction band, then wrapping filling adhesive tape and absolutely
Originate from adhesive tape；
Step 6: on the basis of, wrap adhesive waterproof tape and semi-conductive tape for all cores, and copper shield net and ground wire are installed；
Step 7: being moved to joint location for thermoplastic sealing sheath pipe, distinguishes after being heated cooling at protecting pipe both ends
Wind adhesive waterproof tape.
Further, the length according to needed for single-phase cable connection (length of 5-6 in figure) determines the length of cable connector simultaneously
Determine the length that cable end external sheath layer strips, wherein armouring fracture distance oversheath fracture length and armouring are apart from inner sheath
The length of fracture is required referring to previous technique.
The invention has the advantages that:
Present invention transition joint as made from this method effectively avoids the weak spot of cable from appearing in same position, small electric cable
Bending degree, and effectively reduce the thickness wrapped up outside connector, facilitate the installation of thermoplastic sealing sheath pipe, security performance obviously mentions
It rises.
Detailed description of the invention
Fig. 1 is the production structural schematic diagram of three-core cable transition joint of the invention.
In figure: 1- external sheath layer, 2- armouring, 3- inner restrictive coating, 4- copper shield, 5- semi-conductive layer, 6- insulating layer, 7- line
Core.
Specific embodiment
To keep the purposes, technical schemes and advantages of the invention implemented clearer, below in conjunction in the embodiment of the present invention
Attached drawing, technical solution in the embodiment of the present invention is further described in more detail.In the accompanying drawings, identical from beginning to end or class
As label indicate same or similar element or element with the same or similar functions.Described embodiment is the present invention
A part of the embodiment, instead of all the embodiments.The embodiments described below with reference to the accompanying drawings are exemplary, it is intended to use
It is of the invention in explaining, and be not considered as limiting the invention.Based on the embodiments of the present invention, ordinary skill people
Member's every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.Under
Face is described in detail the embodiment of the present invention in conjunction with attached drawing.
As shown in Figure 1, cable includes external sheath layer 1, armouring 2, inner restrictive coating 3, copper shield 4, semi-conductive layer 5, insulation
Layer 6 and core 7.In-between connector the production method is as follows:
1, the length according to needed for single-phase cable connection (length of 5-6 in figure) determines the length of cable connector and determines cut cable
The length that portion's external sheath layer 1 strips, wherein 2 fracture distance oversheath of armouring, 1 fracture length and armouring are apart from 3 fracture of inner sheath
Length is required referring to previous technique；
2, after stripping armouring 2, inner restrictive coating 3 as requested, expose three cable cores 7 of copper shield 4, keep a cable
The length of core is constant, other cable core equidimensions successively truncate；
3, the copper shield 4, semi-conductive layer 5 and insulating layer 6 of the equal length of every cable core are stripped respectively, are exposed identical
The cable core 7 of size；
4, thermoplastic sealing sheath pipe is inserted in cable one end；
5, as requested by the every core connection of two cables, and half conduction band is wrapped, then wrapping fills adhesive tape and insulation certainly
Adhesive tape；
6, on the basis of, wrap adhesive waterproof tape and semi-conductive tape for all cores, and copper shield net and ground wire are installed；
7, thermoplastic sealing sheath pipe is moved to joint location, is wound respectively after being heated cooling at protecting pipe both ends anti-
Glue band.
To sum up, cable core is attached by traditional cable intermediate joint production method in same position, due to every
Core wire outer wrap adhesive waterproof tape and semi-conductive tape make joint area form bigger protuberance, cause core wire in joint area shape
At biggish radian, simultaneously, it has not been convenient to which thermoplastic sealing sheath pipe is installed.With the increase for using the time, such cable connector
It is easy to appear failure, causes bigger accident.This law invents the production method for proposing a kind of three-core cable transition joint, effectively
The drawbacks of avoiding conventional fabrication method improves the security performance of cable intermediate joint.
One embodiment of the present invention above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously
Limitations on the scope of the patent of the present invention therefore cannot be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, under the premise of not departing from present inventive concept and principle, various modifications and improvements can be made, these belong to this hair
Bright protection scope.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
