The length of the draw, makes the two ends of described second heat-shrink tube respectively beyond the two ends of described first heat-shrink tube；
F, described second heat-shrink tube is heated, make heat-shrink tube fit tightly with transition joint.
In described step A, the outside partly formula of taking of the transition joint formed at each fibre core connected and insulating barrier is wrapped
Insulating tape, the two ends of insulating tape are covered each by the outer jacket on each cable of correspondence, preliminarily form transition joint.
In described step A, from the other end of one end of described transition joint to transition joint, formula of the most partly taking is wound around high pressure
Rubber self-adhesive tape, it is ensured that the two ends of high pressure rubber self-adhesive tape are respectively beyond the two ends of described transition joint.
Having shielding line in described cable, in described step A, be also wrapped on the screen layer connected insulating tape.
The mode of being wrapped of the high pressure rubber self-adhesive tape in step D is: from one end and the transition joint of described first heat-shrink tube
Seam to the seam of the other end and the transition joint of described first heat-shrink tube partly take formula continuous winding, it is ensured that high rubber from
Adhesive tape is beyond the two ends of described first heat-shrink tube.
In step, before each fibre core on cable connects, described first, second heat-shrinkable T bush is sleeved in advance
On cable.
The invention has the beneficial effects as follows: the manufacture method of a kind of cable transition joint of the present invention is in the outside of transition joint
It is set with the first heat-shrink tube, and at described first heat-shrink tube high pressure rubber wrapped with the seam on corresponding cable self-adhesive tape, protects
Demonstrate,prove the sealing of each seam, then be set with the second heat-shrink tube, the two ends of described second heat-shrink tube in the outside of described first heat-shrink tube
All cover the high pressure rubber self-adhesive tape beyond the first corresponding heat-shrink tube two ends；Compared to prior art, the inventive method is formed
Transition joint waterproof, humidity resistance is more preferable.
Accompanying drawing explanation
Fig. 1 is the flow chart of the specific embodiment of the manufacture method of a kind of cable transition joint of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings embodiments of the present invention are described further.
The specific embodiment of the manufacture method of a kind of cable transition joint of the present invention, as it is shown in figure 1, a kind of cable is moistureproof
Type transition joint manufacture method, this example is based on YPY type φ 8mm, 2*0.2mm cable, and concrete grammar comprises the steps:
1, it is cleaned cable processing, judges divesting length and being stripped (oversize waste of two joints according to practical situation
Material, the shortest is difficult to wiring), the length that divests of both threads cable crust is about 30mm herein, to facilitate joining operations；
2, analog quantity cable usually contains screen layer, with wire stripper by two cable insulation layer and internal shield strip off.
3, with wire stripper, two cables are needed the fibre core strip off connected, determines the length of its strip off according to actual requirement, this
Place's both threads cable fibre core divests length and is about 15mm, is twisted respectively by the shielding line on exposed each bar fibre core and screen layer
One；
3.1, according to the most stand-by outer corresponding diameter of suit in the thickness of cable and an associated specifications cable wherein and length
Spend the most unequal inside and outside heat-shrink tube, a diameter of φ 10mm of interior heat-shrink tube, a length of 7cm, a diameter of φ of outer heat-shrink tube
12mm, a length of 11cm；
4, require according to actual needs respectively corresponding will need the fibre core connected and be twisted one together after bend inflection, and and
Corresponding former line together, to ensure the contact area of each fibre core, screen layer connection the most in this way process；
5, on each fibre core connected and covered wire, be wound around the insulating tape of 1～2 layer respectively, make between each fibre core mutually every
From, insulation；
5.1, the fibre core one connected in previous step is reinstated 1～2 layer of insulating tape to be wrapped, preliminarily forms transition joint,
And ensure that transition joint forms insulation to external world；
5.2, by 10# high pressure rubber self-adhesive tape (19mm × 5yd × 0.8mm), firmly by the cable connector that connects by one end
Formula of partly taking to the other end is around 1～2 layer, and each layer will wrap up the outward flange of the insulating tape beyond previous step, observes joint
Full closely knit；
6, by the less interior heat-shrink tube in the middle of step 3.1, the length beyond previous step high pressure rubber self-adhesive tape is wrapped up；
6.1, then according to on-the-spot physical condition, with heat gun or windproof lighter by heat-shrink tube heat shrink, pyrocondensation is made
Manage the tight high pressure rubber self-adhesive tape wrapping previous step；
7, by 10# high pressure rubber self-adhesive tape (19mm × 5yd × 0.8mm), firmly by the cable connector that connects by one end to
The other end partly takes formula around 1～2 layer, and each layer will wrap up the seam of the heat-shrink tube beyond previous step and corresponding cable, makes height
Pressure self-adhesive tape is fitted tightly on interior heat-shrink tube, it is ensured that the sealing of each seam；
8, by the outer heat-shrink tube being relatively large in diameter in the middle of step 3.1, wrapped up beyond previous step high pressure rubber self-adhesive tape
Length；
9, according to on-the-spot condition, with heat gun or windproof lighter by heat-shrink tube heat shrink, the bag that heat-shrink tube is tight is made
Wrap the high pressure rubber self-adhesive tape of last layer；In order to attractive in appearance, outer heat-shrink tube can be chosen as with cable outer jacket solid colour or
Person is close.
In other embodiments of the manufacture method of a kind of cable transition joint of the present invention, it is also possible to by step 7
The mode of being wrapped of high pressure rubber self-adhesive tape changes into: the only seam at heat-shrink tube Yu each cable is wrapped, the centre of heat-shrink tube
Part need not be wrapped.
In other embodiments of the manufacture method of a kind of cable transition joint of the present invention, it is also possible to skip over step 5.1
With 5.2, for waterproof, the humidity resistance of transition joint, insulating tape in step 5.1 and 5.2 and high pressure rubber from
Adhesive tape can also be not provided with.
In other embodiments of the manufacture method of a kind of cable transition joint of the present invention, in steps of 5 can not also
Be wrapped on covered wire insulating tape.
In other embodiments of the manufacture method of a kind of cable transition joint of the present invention, it is also possible to skip over step 3.1,
According to practical situation, wherein the two ends of a cable are disconnection, heat-shrink tube can be installed from this cable one end to
At transition joint.
In other embodiments of the manufacture method of a kind of cable transition joint of the present invention, it is also possible to according to actual need
, such as more waterproof to transition joint, humidity resistance requires higher occasion, overlaps the most successively in the outside of second layer heat-shrink tube
If one layer or the heat-shrink tube of multilamellar, the length of each layer of heat-shrink tube is more than the length of last layer heat-shrink tube, and respectively to first
Heat-shrink tube heating between heat-shrink tube and the outermost heat-shrink tube of transition joint, then at the seam of this layer with corresponding cable
It is wound around high pressure rubber self-adhesive tape, it is ensured that the sealing of each seam, finally outermost heat-shrink tube is heated.
