Embodiment
By describing technology contents of the present invention, structural feature in detail, realized purpose and effect, give explanation below in conjunction with execution mode and conjunction with figs. are detailed.
See also Fig. 1, sleeve pipe 10 of the present invention comprises main sleeve pipe 11, protrudes out the branch joint 12 that is communicated with main sleeve pipe 11 on the sidewall of main sleeve pipe 11, and in the present embodiment, the caliber of branch joint 12 is less than the caliber of main sleeve pipe 11.
In the present embodiment, branch joint 12 and main sleeve pipe 11 are parallel and be arranged side by side.Certainly, branch joint and main sleeve pipe can also arrange as required at an angle, and this angle can be between the 0-180 degree, and sleeve pipe 10 is preferably shrinkage sleeve pipe or heat-shrinkable T bush.
See also Fig. 2, sleeve pipe 10 of the present invention discloses a kind of encapsulating method of drawing of cable ground wire, the screen of cable 20 leads to shielding earth 21, be with above-mentioned sleeve pipe 10 on the cable, wherein main sleeve pipe 11 is placed on the cable 20, branch joint 12 is placed on the shielding earth 21, and shielding earth 21 is drawn from branch joint 12.
Preferably, to draw the method for shielding earth be shielding earth to the screen of described cable 20 is connected with screen in the mode of welding or crimping.
Sleeve pipe 10 of the present invention and ground clamp cable be enclosed within cable outside cold shrink tube between and fill roundings and compare with the prior art of eliminating the space by filling a large amount of glue, not only realized the closed outlet of shielding earth 21, the main sleeve pipe 11 of sleeve pipe 10 is integrally formed with branch joint 12, the main sleeve pipe 11 of sleeve pipe 10 and the direct rounding sealing of cable, greatly strengthened sealing effectiveness, and saved and fill a large amount of operations of filling glue, technology is simple, the installation effectiveness height can be saved cost.
See also Fig. 3, sleeve pipe 10 of the present invention discloses a kind of encapsulating method of drawing of cable ground wire, and this cable also comprises the armouring ground wire 22 of drawing from the armour of cable 20 except comprising the shielding earth 21 that screen is drawn.
Be with two above-mentioned sleeve pipes 10 on the cable, wherein the main sleeve pipe 11 of a sleeve pipe 10 is placed on the oversheath of cable 20, and branch joint 12 is placed on the armouring ground wire 22, and armouring ground wire 22 is drawn from branch joint 12.
The main sleeve pipe 11 of another sleeve pipe 10 is placed on the inner sheath of cable 20 and part is enclosed within on the main sleeve pipe 11 of the sleeve pipe 10 that is placed in cable, and branch joint 12 is placed on the shielding earth 21, and shielding earth 21 is drawn from branch joint 12.
Preferably, to be shielding earth 21 be connected with screen in the mode of welding or crimping the method that the screen of cable 20 is drawn shielding earth 21, and the method that the armour of cable 20 is drawn armouring ground wire 22 is armouring ground wire 22 to weld or the mode of crimping is connected with armour.
For the cable that has armour, adopt two sleeve pipes 10 to be enclosed within on the inside and outside sheath of cable respectively earth connection respectively and draw sealing, it is the sealing of drawing of shielding earth 21 and armouring ground wire 22, thereby the external sheath layer that has solved cable is sealed to the insulating barrier protection of cable and uses same cold shrink tube, the pipe internal diameter that causes owing to oversheath is different with the diameter of inner sheath select unreasonable problem for use.
Adopt two sleeve pipes 10 to be enclosed within respectively to have solved the oversheath that the armour cable is arranged on the inside and outside sheath of cable thick more a lot originally than the inner sheath insulating barrier of cable, its external diameter increases again much after adding cable armouring ground wire and oversheath encapsulation process, this has caused with the external diameter great disparity of insulating barrier excessive, if be in big expansion state with same pipe all the time at armour, after being scratched, the problem that might split fully; And solved same pipe and shrink not in placely in insulation position probably, there is the problem in space.
The range of application of sleeve pipe is not limited to the sealing of drawing of cable ground wire, and every large and small two parts that relate to branch's sealing or vicinity all can adopt bobbin seal of the present invention.
The present invention is not limited to above-mentioned embodiment, and those skilled in the art that also can make multiple variation accordingly, but any and the present invention are equal to or similar variation all should be encompassed in the scope of claim of the present invention.
