Apply example to be only used to explain the utility model, be not used to limit the utility model.
As Figure 1-3, a kind of bolted anti-loose structure of wire, wire is connected by line nose with bolt, its bag
Anti- DNA releaxed circular DNA 1, the connect band 2 for being adhered to the wire card 3 of wire and being connected between anti-DNA releaxed circular DNA 1 and wire card 3 are included, anti-DNA releaxed circular DNA 1 glues
It is connected on the nut end face coordinated with bolt；Connect band 2 can bend to nut axis direction, and in the tangential direction of nut
In rigidity.Nut is relatively fixed with wire by connect band 2, nut is not loosened.Wire card 3 is Nian Jie with wire, locking
Ring 1 is Nian Jie with nut, can carry out later stage locking reinforcing to the wire interconnecting piece position for having been connected with screw bolt and nut, without
Need to take apart junction, it is easy for installation simple, it is adaptable to be installed in narrow space.
In implementation, as shown in figure 1, anti-DNA releaxed circular DNA 1 is the flat ring-type being made up of insulating materials such as nylon, anti-DNA releaxed circular DNA 1
Outer rim extends strip, laminar connect band 2, and connect band 2 is parallel to anti-DNA releaxed circular DNA 1.The inside of connect band 2 is flat metal
Piece, external sheath insulating barrier 22.Connect band 2 can bend to two sides, and the rigidity of inflexibility is presented in the direction of the width；
After i.e. the bolted anti-loose structure of wire is arranged at the bolt connection of wire, connect band 2 can be curved to nut axis direction
Folding, and in rigidity in the tangential direction of nut.The other end of connect band 2 is wire card 3, and wire card 3 can be to be bonded in lead
U-lag on line, connect band 2 is connected to U-lag bottom land.When using, after the bolt of connecting position of wires is tightened, in anti-DNA releaxed circular DNA 1 one
Face and wire card 3 coat insulating cement, and anti-DNA releaxed circular DNA 1 is enclosed within the screw rod end of bolt, and the one side for scribbling insulating cement is bonded at nut end
On face, then wire card 3 is bonded on wire.After installation, connect band 2 bends in nut axis direction, makes anti-DNA releaxed circular DNA 1 and leads
Line card 3 adapts to difference in height and differential seat angle between nut and wire.The width of connect band 2 is tangent with nut, the width of connect band 2
Rigidity on direction prevents that nut is rotated from opposing leads, prevents nut from rotating and loosens.Connect band 2 is not limited in above-mentioned knot
Structure, it is only necessary to ensure, connect band 2 can bend to nut axis direction after installation, and in rigidity in the tangential direction of nut,
It is included within the technical solution of the utility model.
Further, as shown in figure 3, wire card 3 is two, the both sides of anti-DNA releaxed circular DNA 1 are respectively arranged at；Connect band 2 is two
It is individual, it is connected between two wire cards 3 and anti-DNA releaxed circular DNA 1.Connected suitable for two wires are relative, two wire cards 3 are distinguished
It is connected on two wires, more firmly, anti-loosing effect is more preferable for connection.In implementation, the monosymmetric of anti-DNA releaxed circular DNA 1 is connected with two
The individual laminar connect band 2 of strip, the end of two connect bands 2 is connected to wire card 3.
Further, as Figure 1-3, connect band 2 be strip, flake, and connect band 2 width parallel to spiral shell
Female end face；The one end of connect band 2 is connected to anti-DNA releaxed circular DNA 1, and the other end is connected to wire card 3.Simple structure, reliability is high, convenient
It is practical.
Further, as Figure 1-3, wire card 3 is the U-lag that elastomeric material makes, and the open end of U-lag is provided with
The projection for preventing wire from deviating from, U-lag bottom land connection connect band 2.Clamping is convenient, and the side wall of U-lag undertakes locking moment of torsion, subtracts
Few U-lag stress Nian Jie with wire, makes U-lag be difficult to be come off from wire.
Further, anti-DNA releaxed circular DNA 1 is adhered to nut end face by insulating cement, and wire card 3 is adhered to wire by insulating cement.
Using the locking ring 1 of the glue sticking that insulate and nut, wire card 3 and wire, the insulating properties of connecting position of wires are not interfered with.Insulating cement
The technical scheme of this practicality type can also be readily adaptable for use in using the insulating cement for being also resistant to insulating oil, be soaked in
Wire connection in insulating oil.
Further, as shown in figure 4, connect band 2 includes the insulating barrier 22 of metallic framework 21 and the outer cladding of metallic framework 21.
Connect band 2 had both been kept certain intensity, the insulating properties of connecting position of wires are not interfered with again, prevent wire bolted anti-
Loose structure one end releases the short circuit accident occurred after rear or entirety comes off.In implementation, the inside of connect band 2 is thin for the strip of steel
Piece, outside is coated with electro-insulating rubber, makes connect band 2 powered.
Further, as Figure 2-3, anti-DNA releaxed circular DNA 1 is provided with being sticked in the claw 11 of hex nut side.Set
The structure of claw 11, transmits the moment of torsion between anti-DNA releaxed circular DNA 1 and nut, reduces stress Nian Jie between anti-DNA releaxed circular DNA 1 and nut, makes connection
It is more firm.
In implementation, claw 11 can be six clamps into hexagonal array that the side of locking ring 1 is set；When using, six
Individual clamp is fastened on six sides of nut.Six clamps can only set wherein several, but at least two are located at hexagon
Relative edge set.Additionally, anti-DNA releaxed circular DNA 1 is also provided with the groove of hexagon, six sides of groove equivalent to claw 11,
The groove of anti-DNA releaxed circular DNA 1 is buckled on nut when using is engaged.
Preferred embodiment of the present utility model is these are only, is not used to limit the utility model, it is all in this practicality
