Abstract
The utility model discloses a power cable sealing and protecting sleeve, which comprises a nylon skeleton, a compression nut, and an elastic sealing sheath. The nylon skeleton is provided with a ring structure. The outer wall of the nylon skeleton is provided with a screw thread and the bottom with an outer edge. The lower part of the nylon skeleton extends out of a connection cylinder. The connection cylinder and the outer edge are injected as one mode. The external screw thread of the nylon skeleton matches with the compression nut; one end of the elastic sealing sheath is wrapped to the connection cylinder while the other end is tightly sleeved to the outer part of the power cable. The sleeve of the utility model not only effectively prevents moistened air from entering a piece of electric equipment so as to ensure the electric equipment to function well, but it also has a simple structure and is convenient to install and maintain, therefore, significantly reducing manufacturing cost for a power supply facility.
Description
Technical field
The utility model relates to a kind of cable seal protective jacket, and a kind of especially for sealing, the cable of electrical equipment box body goes out or the device of entrance hole, belongs to cable technology field.
Background technology
The equipment facility that some and the cable such as cable distribution box, high-low voltage electric power distribution cabinet are used in combination,, often there are some sealing problems in the cable that it is inner or electric wire wire hole, causes underground moisture through the operation of cable aperture access arrangement internal influence electric equipment.Particularly, in the cable trough of outdoor electricity distribution equipment, when rainwater is large, exist current to enter the situation that forms ponding in cable trough, very easily cause the generation of distribution accident.At present, the moisture protection to cable aperture, is divided into three kinds substantially:
One. adopt anti-chamotte to carry out shutoff cable aperture.This anti-chamotte is also organic/inorganic fire prevention calking, and it can soften when summer, and weather shrinks when cool and can form crack, and sealing effectiveness is not fine.
Two. adopt blowing agent that cable aperture is blocked.This method for blocking permeability resistance is poor, should not be for moistureproof engineering.
Three. adopt fireproof seal gum or cement etc., but its effect is all undesirable and be unfavorable for the safe operation of equipment later maintenance having been brought to a large amount of work.
Several method in sum, and cannot reach preferably the moisture protection to cable aperture, so insider, in the urgent need to a kind of simple in structure, easy to maintenance, and can be effective to the device of cable aperture protection against the tide.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, the cable seal protective jacket that a kind of good sealing effect, low cost of manufacture and being convenient to safeguarded.
Problem described in the utility model is solved by following technical scheme:
A cable seal protective jacket, it comprises polyamide skeleton, clamp nut and elastic packing sheath, and described polyamide skeleton is circulus, and its outer wall is provided with external screw thread, and bottom is provided with outer; Connecting cylinder is extended in the bottom of described polyamide skeleton, and connecting cylinder and outer are injected into one, and the external screw thread of described polyamide skeleton and the screw thread of clamp nut match; One end of described elastic packing sheath is coated on connecting cylinder, and the other end is tightly placed in the outside of cable.
Above-mentioned cable seal protective jacket, sets up seal gasket, and described seal gasket is annular, is arranged between outer and clamp nut.
Above-mentioned cable seal protective jacket, sets up convex tendon at the outer wall of connecting cylinder.
Above-mentioned cable seal protective jacket, described elastic packing sheath inside is provided with helical form plastic support bar.
The utility model utilizes polyamide skeleton, ring packing rubber cushion and elastic packing sheath to seal cable aperture, not only can effectively prevent that external humidification from entering inside electric appliance, guarantee the normal operation of electric equipment, and simple in structure, convenient for installation and maintenance, greatly reduced the construction cost of power supply facilities.In addition, because elastic packing sheath is cold contraction type structure, so after installing without worrying that it is because moving or bending, and affect the sealing of cable.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is that Fig. 1 does not remove plastic support bar structural representation;
Fig. 3 is polyamide skeleton structural representation.
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.
Referring to Fig. 1～Fig. 3, the utility model mainly consists of the following components:
1. polyamide skeleton 1: its polyamide skeleton 1 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: for preventing from sealing the panel beating burr injury elastic packing sheath on tank wall 8, in addition, can also effectively strengthen and seal the sealing between tank wall 8.It is after fixing by clamp nut, airtight being attached to around the cable aperture that seals tank wall 8 tightly.
3. clamp nut: Main Function is to coordinate fixedly elastic packing sheath of polyamide skeleton, makes its fastening cable aperture place that is pressed on.
4. elastic packing sheath: be to utilize elastomeric material (conventional have silicon rubber and ethylene-propylene rubber) to inject sulfidization molding then the parts that form with helical form plastic support bar through hole enlargement, lining in factory.Sealing chilling shrink type cable accessory one end is held on cassette polyamide skeleton, make it can lean on the wiper seal cable aperture of cassette polyamide skeleton clamping, by the plastic spiral bar in shrinkage annex, support below, these predilation parts are enclosed within cable end piece or joint after treatment, extract the plastic spiral bar (supporter) of inner support out, be pressed on cable insulation, and the electric cable accessories forming.Because it is at normal temperatures by elastical retraction power, cold contracting type cable accessory have volume little, easy to operate, rapid, without specific purpose tool, the advantage such as the scope of application is wide and product specification is few.During on-the-spot installation, first polyamide skeleton 1 is pushed to cable aperture, the clamp nut of tightening is above fixed, construction cable passes through from polyamide skeleton, clamp nut and elastic packing sheath, after to be onstructed, below elastic packing sheath, extract again helical form plastic support bar out, can allow elastomeric material burden tightly on cable insulation, tube connector or transition connecting pipe, thereby play the effect of sealing.
5. convex tendon: the strip structure that described convex tendon is convex, along the outer wall setting of connecting cylinder the latter half.Can effectively strengthen the frictional force between elastic packing sheath 4 and connecting cylinder 7, make between them fixing more fastening.
