Description
Technical Field
The utility model relates to a wire fixing device suitable for porcelain cross arm insulator.
Background
Along with the use widely on a large scale of overhead insulated wire, adopt traditional BV to tie up the fixed connected mode of wire with insulated wire and porcelain cross arm insulator and appeared more and more problem. Particularly, in coastal areas, the insulation layer of the wire at the binding wire part is often damaged due to long-time wind vibration stress corrosion and strong salt mist corrosion, and the phenomena of discharge and pollution flashover sometimes occur along with the aggravation of exposed corrosion of the conductor of the insulated wire, so that the insulation layer is finally burnt and broken. This not only greatly increased the circuit maintenance work load, seriously influenced the operational reliability of joining in marriage the net line moreover. The prior similar fixing wire clamp structures are slightly complicated, have more corrosion points and are not suitable for coastal high-salt-mist areas.
Disclosure of Invention
The utility model aims at providing a wire fixing device suitable for porcelain cross arm insulator, the device simple structure facilitates the use, and the pliability is good, can protect the wire insulating layer.
The technical scheme of the utility model lies in: the utility model provides a wire fixing device suitable for porcelain cross arm insulator, includes the semicircle staple bolt, the inboard of semicircle staple bolt is provided with the staple bolt boss, the both ends of semicircle staple bolt are provided with the wire chuck, be provided with the fastener on the wire chuck.
Furthermore, the inner surface of the hoop boss is a semicircular arc surface, the semicircular arc surface and the porcelain cross arm insulator form loose fit, and the edge of the semicircular arc surface is provided with a fillet.
Furthermore, the semicircular hoop and the hoop boss are integrated, and the cross section of the semicircular hoop and the hoop boss is rectangular.
Furthermore, the wire chuck is a notch ring, the cross section of the wire chuck is C-shaped, fastening bosses are arranged on two sides of the notch of the wire chuck, through holes are formed in the fastening bosses, and the two fastening bosses are connected through fasteners.
Furthermore, reinforcing ribs are arranged on two sides of the wire clamp.
Furthermore, the axis of the semicircular hoop is perpendicular to the axis of the lead chuck.
Furthermore, the axis of the semicircular hoop and the lead chuck are both made of flexible materials through injection molding.
Compared with the prior art, the utility model has the advantages of it is following: the novel structure is simple, the use is easy, the semicircular hoop and the hoop boss can be matched with the groove of the porcelain cross arm insulator, the damage to the insulating layer of the wire is reduced, and the service life of the insulated wire is prolonged; and meanwhile, the dismounting is convenient, and the maintenance labor cost is reduced.

Detailed Description
In order to make the aforementioned features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below, but the present invention is not limited thereto.
Refer to fig. 1-3.
The utility model provides a wire fixing device suitable for porcelain cross arm insulator, includes the semicircle staple bolt, the inboard of semicircle staple bolt is provided with the staple bolt boss to fix in the recess of porcelain cross arm insulator, the both ends of semicircle staple bolt are provided with the wire chuck, with fixed insulated wire, be provided with the fastener on the wire chuck.
In this embodiment, the internal surface of staple bolt boss is the semicircle cambered surface, the semicircle cambered surface constitutes loose cooperation with porcelain cross arm insulator to in the dismantlement installation, do not influence fixed effect again simultaneously, can not rock in the recess, the edge of semicircle cambered surface is provided with the fillet to suit with porcelain cross arm insulator's fillet.
In this embodiment, semicircle staple bolt and staple bolt boss formula as an organic whole, its cross-section is the rectangle, and the width of semicircle staple bolt and staple bolt boss equals promptly, has increased the area of contact with porcelain cross arm insulator, improves the holistic anticreep performance of wire fixing device.
In this embodiment, the wire chuck is a breach ring, and its cross-section is "C" type for imbed insulated wire, the breach both sides of wire chuck all are provided with the fastening boss, all set up the through-hole on the fastening boss, two fastening bosses pass through the fastener and connect, the fastener is bolt, nut and gasket usually, through screwing up the bolt for the diameter of wire chuck diminishes, presss from both sides tight insulated wire.
In this embodiment, the both sides of wire chuck are provided with the strengthening rib to increase wire chuck intensity, avoid destroying.
In this embodiment, the axis of the semicircular hoop is perpendicular to the axis of the wire chuck, so as to ensure the position relationship between the insulated wire and the porcelain cross arm insulator.
In this embodiment, the axis of semicircle staple bolt all adopts flexible material to mould plastics with the wire chuck and makes, flexible material is the polymer composite who has rubber and plastics material characteristic concurrently usually, can resist the insulating wire pressure of drawing that the waving caused with the wind, avoids insulating wire waving range too big to cause the fixed fastener body to tear. Meanwhile, a certain opening angle can be broken off during mounting and dismounting, and the insulator can be matched with an insulated wire and a porcelain cross arm insulator. And the hardness of the insulating layer is lower than that of the insulating layer of the insulated wire, so that the insulating layer of the insulated wire is prevented from being damaged in friction, and the service life is prolonged.
The working principle is as follows: the semicircular hoop is attached to a groove of the porcelain cross arm insulator tightly, the wire chuck is broken into a certain opening angle and the insulated wire is inserted, and the insulated wire is connected with the porcelain cross arm insulator by tightening a fastener on the wire chuck.
The above is only the preferred embodiment of the present invention, and all the equivalent changes and modifications made according to the claims of the present invention should be covered by the present invention.
