Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, easy to maintenance, and moisture effect is good, and is applicable to seal the minor diameter cable seal protective jacket of minor diameter cable.
Problem described in the utility model is solved by following technical scheme:
A kind of minor diameter cable seal protective jacket, it comprises polyamide skeleton, clamp nut, reducing transition sheath and elastic packing sheath; Described polyamide skeleton and clamp nut threaded engagement; One end of described elastic packing sheath is coated on connecting cylinder, and the other end is tightly placed in reducing transition sheath; Described reducing transition sheath is made up of transition connecting pipe and minor diameter elastic packing sheath, described transition connecting pipe is between cable and elastic packing sheath, one end of described minor diameter elastic packing sheath is tightly placed in the outside of transition connecting pipe and elastic packing sheath, and the other end is directly tightly placed on cable.
Above-mentioned minor diameter cable seal protective jacket, sets up seal gasket, and described seal gasket is annular, is arranged between outer and clamp nut
Above-mentioned minor diameter cable seal protective jacket, sets up convex tendon, and described convex tendon is separately positioned on the outer wall of transition connecting pipe and connecting cylinder.
Above-mentioned minor diameter cable seal protective jacket, described elastic packing sheath and minor diameter elastic packing sheath inside are equipped with helical form plastic support bar.
The utility model utilizes polyamide skeleton, ring packing rubber cushion and elastic packing sheath to seal the cable aperture on sealing tank wall, not only can effectively prevent that external humidification from entering inside electric appliance, ensure the normal operation of electric equipment, and simple in structure, convenient for installation and maintenance, greatly reduce the construction cost of power supply facilities.In addition, the utility model, also by reducing transition sheath, has solved in the time meeting the cable of minor diameter effectively, mates not good and problems such as sealing reduction that cause.And the elastic packing sheath in the utility model and minor diameter elastic packing sheath are cold contraction type structure, thus after installing without worrying that it is because moving or bending, and affect the sealing of cable.
Brief description of the drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the structural representation of connecting cylinder;
Fig. 3 is the structural representation that Fig. 1 does not remove helical form plastic support bar.
In figure, each list of reference numerals is: 1. polyamide skeleton, 2. clamp nut, 3. seal gasket, 4. elastic packing sheath, 5. cable, 6. sealing tank wall, 7. connecting cylinder, 8. convex tendon, 9. helical form plastic support bar, 10. outer, 11. minor diameter elastic packing sheaths, 12. transition connecting pipes.
Embodiment
Referring to Fig. 1～Fig. 3, the utility model mainly consists of the following components:
1, polyamide skeleton 1: it is circulus, and its outer wall is provided with external screw thread, and bottom is provided with outer 10; Connecting cylinder 7 is extended in the bottom of described polyamide skeleton 1, and connecting cylinder 7 and outer 10 are injected into one, and described connecting cylinder tightens the flexible sealing sheath 4 of cover.The external screw thread of described polyamide skeleton and clamp nut 2 threaded engagement.
2, seal gasket 3: for strengthening and sealing the sealing between tank wall 8, after it is fixed by clamp nut, around the airtight cable aperture that is attached to sealing tank wall 8 tightly.
3, clamp nut 2: Main Function is to coordinate polyamide skeleton to fix, and makes its fastening cable aperture place that is pressed on.
4, elastic packing sheath 4 and minor diameter elastic packing sheath 11: utilize elastomeric material (conventional have silicon rubber and ethylene-propylene rubber) injection sulfidization molding, then the parts that form with helical form plastic support bar through hole enlargement, lining.Sealing chilling shrink type cable accessory one end is held on cassette polyamide skeleton, makes its fastening force that can lean on polyamide skeleton and clamp nut reach the effect in hermetically-sealed cable hole, and elastic packing sheath supports 9 by helical form plastic support bar.Elastic packing sheath is enclosed within behind cable end piece or joint, then extracts the plastic spiral bar 9 (supporter) of inner support out, and elastic packing sheath is pressed on cable 5 insulating barriers.Elastic packing sheath has the advantages such as volume is little, easy to operate, rapid, loose and product specification is few without specific purpose tool, the scope of application.When on-the-spot installation, first polyamide skeleton 1 is pushed to cable aperture, tighten the clamp nut matching with it, they are fixed on cable aperture, construction cable passes through from polyamide skeleton and elastic packing sheath, after cable construction, extracts helical form plastic support bar 9 below elastic packing sheath out, can allow elastomeric material burden tightly on the insulating barrier and polyamide skeleton of cable, thereby play the effect of sealing.
5, convex tendon 8: the strip structure that described convex tendon 8 is convex, described convex tendon is separately positioned on the outer wall of transition connecting pipe and connecting cylinder.Can effectively strengthen the frictional force between elastic packing sheath 4 and connecting cylinder 7, make between them fixing more fastening.
6, reducing transition sheath: at some cables 5 diameters in the situation that less than normal, depend merely on polyamide skeleton 1, clamp nut 2, seal gasket 3 and elastic packing sheath 4 and can not effectively hold cable 5 tightly, sealing property can not get good guarantee, therefore set up transition connecting pipe 12 and minor diameter elastic packing sheath 11, make it after secondary shrinks, hold cable 5 tightly, increase the dynamics of holding tightly and tightness to cable.
When on-the-spot installation, first the threaded portion of polyamide skeleton 1 is pushed to the cable aperture on sealing tank wall 6, the clamp nut 2 of tightening is above fixed, cable 5 passes through from polyamide skeleton 1, after cable construction, extract helical form plastic support bar 9 from below out and can allow on the elastic packing sheath external insulation layer that is wrapped in cable tightly, thereby play the effect of sealing.In the time running into small diameter cable, transition connecting pipe 12 is enclosed within on cable 5, make the tight one end overlapped of elastic packing sheath 4 and cable 5 insulating barriers, be tightly placed on transition connecting pipe 12, one end of minor diameter elastic packing sheath 44 is tightly placed on elastic packing sheath 4 and transition connecting pipe 12, the other end is tightly placed on cable 5 again.
