Abstract
The utility model discloses a safe wire passing pipe and belongs to a transitional element for enabling an overhead conductor of an electric energy power system to enter a room or a transformer box. The safe wire passing pipe comprises a sleeve provided with a wire hole at the centre, and a sleeve seat is arranged at the middle part of the sleeve for dividing the sleeve into a wall penetration side and an outer wall side. The safe wire passing pipe is characterized in that the sleeve on the outer wall side is provided with 7-10 climb reinforcing aprons, a sealing rubber pad and a conductor fixing clip are arranged on the top end of the outer wall side, the conductor fixing clip is arranged on the central line of the wire hole, and a fixing hole is arranged on the sleeve seat. When in use, the conductor passing through the wall does not need to be cut off and directly enters the wall through the wire hole, so that the safe wire passing pipe has the following characteristics: 1. two joints are decreased so as not to increase contact resistance to cause heating burn due to long-term application; 2. two exposed points on the conductor with insulating coating are decreased to reduce the potential safety hazard and improve the power supply quality; 3. guide rods, gaskets, nuts and the like are reduced to save 50% of copper materials; and 4. the number of the climb reinforcing aprons is increased to improve the creepage distance and the safety.
Description
Technical field
The utility model provides a kind of safe 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 safe wire-passing tube of break line.
The utility model solves the technological scheme that its technical problem adopted: safe 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 described creeping-increasing skirt is provided with 7-10.Increase wall exterior portions creep age distance
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 safety 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 creeping-increasing skirt is provided with 7-10.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, increased increase climb crowd quantity, improved creep age distance, 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 7.7-10 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. safe 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 described creeping-increasing skirt is provided with 7-10.
