Abstract
The utility model relates to a stable wire transition pipe, and belongs to transition parts for enabling aerial wires of electric power systems to enter a room or a box transformer substation. The stable wire transition pipe comprises a sleeve, the center of the sleeve is provided with a wire passing hole, and a sleeve seat is arranged in the middle of the sleeve to divide the sleeve into a wall passing side and a wall outer side. The stable wire transition pipe is characterized in that the wall outer side of the sleeve is provided with a creep extender, a sealing rubber mat and a wire fixing clip are arranged at the top end of the creep extender, the wire fixing clip is arranged on the center line of the wire passing hole, a fixing hole is arranged on the sleeve seat, and a thread is arranged in the fixing hole. When the stable wire transition pipe is used, a wire passing through a wall can directly enter the wall through the wire passing hole without being broken, so that the stable wire transition pipe has the advantages that two connection points are decreased, the stable wire transition pipe cannot be burned out due to increase of contact resistance in long-term application, two bare points of the wire with an insulated cover are decreased, potential safety hazards are reduced, power supply quality is improved, a guide rod, a gasket, a nut and the like are omitted, copper materials are saved by 50%, a bolt is conveniently used for fixing, the stable effect is enhanced, and safety is improved.
Description
Technical field
The utility model provides a kind of steady type wire-passing tube, belongs in the electric energy electric power system aerial condutor inlet chamber or the interior transition piece of case change.
Technical background
At present, in the electric power system whenever the power supply electric wire need pass the interface, for example: passing in the metope inlet chamber, pass case and become shell and get into case and become inside etc., all is to need to use wall bushing to accomplish.Wall bushing is made up of stub and exterior insulation insulator, and during use, wall bushing is installed in the body of wall.Have following shortcoming in the using process: 1, need break off lead, be connected on the terminal of wall bushing, this just has two contacts of disconnection; Owing to the size of load current changes over time; Time has been grown contact and bad connection can occur, increases heating source, and is accidents caused.2, wall bushing needs compositions such as the guide rod of copper, a plurality of copper backing, a plurality of copper nuts, and cost is high.And the design of the guide rod of wall bushing and contact retaining screw, pad will be higher than the manyfold that lead allows electric current, and copper consumption is high.3, installation, construction relative complex.4, the lead of tape insulation skin will increase by two bare spots, and is unfavorable to safety.
The model utility content
According to above deficiency of the prior art, the technical problem that the utility model will solve is: provide a kind of safe in utilization, do not need the steady type wire-passing tube of break line.
The utility model solves the technological scheme that its technical problem adopted: the steady type wire-passing tube, comprise that the center is provided with the sleeve pipe of threading hole, and the sleeve pipe middle part is through being provided with casing seat; Sleeve pipe is divided into the side through walls and the wall outside; It is characterized in that: the wall outer side sleeve is provided with creeping-increasing skirt, and the top is provided with seal rubber pad and lead fixed folder, and the lead fixed folder is arranged on the threading hole center line; Casing seat is provided with fixed hole, and screw thread is set in the fixed hole.Use bolt easy to use, increase firm effect.
During use, the side through walls of sleeve pipe is inserted in the body of wall, and is fixed on the body of wall through the fixed hole of casing seat.The lead that needed wall is penetrated the body of wall opposite side through threading hole, connect power load or transfer mechanism.The lead fixed of the wall arranged outside of sleeve pipe folder can fixing cord, prevents to become flexible, swing.
Wherein preferred version is:
The wedge shape stiffening rib is set around the side through walls of described sleeve pipe.Make things convenient for sleeve pipe to insert body of wall, and be easy to fix, prevent to become flexible.
The beneficial effect that the utility model steady type wire-passing tube is had is: through at sleeve pipe middle part through casing seat is set; At the wall outer side sleeve creeping-increasing skirt is set; The top is provided with seal rubber pad and lead fixed folder; The lead fixed folder is arranged on the threading hole center line, and casing seat is provided with fixed hole, and screw thread is set in the fixed hole.The lead of crossing wall during use need not break off, and directly gets within the walls through threading hole, so had following characteristics: 1, reduce by two contacts, can not cause contact resistance to increase because of prolonged application, cause heating burnout; 2, the lead of tape insulation skin has reduced by two bare spots, reduces potential safety hazard, improves power supply quality; 3, cancel guide rod, pad, nut etc., practiced thrift copper material 50%; 4, use bolt easy to use, increase firm effect, improved Security.
Description of drawings
Fig. 1 is the structural representation of the utility model,
Fig. 2 is the left view of Fig. 1,
Wherein: 1, sleeve pipe 2, casing seat 3, creeping-increasing skirt 4, lead fixed folder 5, seal rubber pad 6, stiffening rib 7, fixed hole 8, threading hole.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:
Like Fig. 1, shown in 2, wire-passing tube comprises that the center is provided with the sleeve pipe 1 of threading hole 8, casing seat 2, creeping-increasing skirt 3, seal rubber pad 5 and lead fixed folder 4.Sleeve pipe 1 middle part is provided with casing seat 2, and sleeve pipe 1 is divided into the side through walls and the wall outside.Casing seat 2 is provided with fixed hole 7, in the fixed hole 7 screw thread is set.3-5 creeping-increasing skirt 3 of sleeve pipe 1 wall arranged outside, top are provided with seal rubber pad 5 and lead fixed folder 4.Lead fixed folder 4 is arranged on threading hole 8 center lines.Wedge shape stiffening rib 6 is set around the side through walls of sleeve pipe 1.
During use, the side through walls of sleeve pipe 1 is inserted in the body of wall, and is fixed on the body of wall through the fixed hole 7 of casing seat 2.The lead that needed wall is directly penetrated the body of wall opposite side through threading hole 8, connect power load or transfer mechanism then.Lead fixed folder 4 can fixing cord, prevents to become flexible, swing.
Claims (2)
1. the steady type wire-passing tube comprises that the center is provided with the sleeve pipe of threading hole, and the sleeve pipe middle part is through being provided with casing seat; Sleeve pipe is divided into the side through walls and the wall outside; It is characterized in that: the wall outer side sleeve is provided with creeping-increasing skirt, and the top is provided with seal rubber pad and lead fixed folder, and the lead fixed folder is arranged on the threading hole center line; Casing seat is provided with fixed hole, and screw thread is set in the fixed hole.
