Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
In Fig. 2, the technical program provides a kind of elastic wiring device, it consists of a C shape opening elastic wire clamp, a half-round head square neck bolt and a hexagon nut with flange, and described C shape opening elastic wire clamp is through half-round head square neck bolt and hexagon nut with flange is fastening is fixed on support.
Wherein, C shape opening elastic wire clamp comprises the C shape curved surface member 2 that a cross section bending radius is R, openend at C shape curved surface, be respectively arranged with first, second and extend straight flange 2-1 and 2-2, at first, second, extend on straight flange, correspondence is provided with bolt hole 2-3, in order to pass half-round head square neck bolt.
At the end of the first prolongation straight flange, be provided with a spacing bending edges 2-4.
On support 1, offer regular polygon hole 1-1.
Half-round head square neck bolt 3 is set in regular polygon hole.
At the opposite side of support, C shape opening elastic wire clamp is set.
Its half-round head square neck bolt 3 is fastenedly connected with described hexagon nut with flange 4 rotations after running through the bolt hole on first, second prolongation straight flange.
Further, at the end of the second prolongation straight flange, being provided with cross section bending radius is the half C shape curved-surface structure 2-5 of r.
The openend of its half C shape curved-surface structure arranges towards the first prolongation straight flange 2-1.
On support, the shape of cross section of the hole shape of regular polygon hole 1-1 and described half-round head square neck bolt square neck part 3-1 matches.
As seen from the figure, the longitudinal axis of spacing bending edges 2-4 and C shape opening elastic wire clamp the first prolongation straight flange is perpendicular.
In other words, C shape opening elastic wire clamp first extends the spacing bending edges on straight flange, with the setting that matches of the position of support side.
Further, between support and C shape opening elastic wire clamp, be provided with conducting strip 5.
This conducting strip and C shape opening elastic wire clamp fix as one through punching press or spot welding.
Bolt hole described in it is circular hole, elliptical aperture or slotted hole.
Because adopting tin bronze material (having good elasticity and conductivity), makes C shape opening elastic wire clamp, as much as possible little in order to guarantee the contact resistance between itself and support, therefore between support and C shape opening elastic wire clamp, be provided with the conducting strip of being made by copper product, to guarantee that the contact resistance between support and C shape opening elastic wire clamp meets code requirement.
During actual fabrication, first on the wiring support of equipment, go out eight limit square holes, be pressed into (tightly) half-round head square neck bolt, half-round head square neck bolt and support are connected as a single entity, are loaded on this elastic wiring device, utilize the spacing bending edges on the first prolongation straight flange, limit whole elastic connecting wire clamp upper and lower, activity on the three degree of freedom of left and right, rotation, prevents that whole elastic wiring device from following rotation because of what the rotation of nut occurred, and then realizes the restricted location to this elastic connecting wire clamp.
Compare with existing binding clip, this device adopts hexagon nut with flange and half-round head square neck bolt to match, can save a faced washer and a spring washer, both can reduce install operation process and step, can reduce the manufacturing cost of whole termination again, also can reduce because of in the equipment that the drops to cavity of Assembly part or the earth fault hidden danger of bringing between binding post and shell.
In Fig. 3 and Fig. 4, after screwing between hexagon nut with flange 4 and half-round head square neck bolt 3 and putting in place, hexagon nut with flange is exerted pressure by extending straight flange 2-2 to second of C shape opening elastic wire clamp, the opening of C shape curved surface member 2 is dwindled, utilize C shape open circles cylinder line ball mode, the the first connection wire 6 that is arranged in C shape curved surface member is held with a firm grip, thereby realized C shape opening elastic wire clamp and the reliable connection being connected between wire.
Meanwhile, because the second prolongation straight flange 2-2 draws close to the first prolongation straight flange 2-1, half C shape curved-surface structure 2-5 also can be pressed in half C shape curved-surface structure and first by the second connection wire 7 wherein and extend between straight flange 2-1, thereby realizes fixing to the crimping of the second connection wire and be reliably connected.
This elastic wire clamp utilizes the elasticity of C shape cylindrical hole, puts into wire, screws nut, and clamping platen makes wire firmly be connected with wire clamp.Unclamp nut and open wire clamp, utilize C shape cylindrical hole elasticity to loosen wire, can pull down easily wire.
Owing to being provided with C shape curved surface member and half C shape curved surface member on C shape opening elastic wire clamp simultaneously, make this elastic connecting wire clamp can connect the wire of two kinds of different wire diameters simultaneously, in other words, this elastic connecting wire clamp can two kinds of different wire diameter wires of simultaneous adaptation connection and without changing binding clip, the adaptive surface of this product is expanded.
Because the body of its elastic connecting wire clamp is one, by screwing hexagon nut with flange, utilize the restriction positioning action of spacing bending edges 2-4, can control the upper and lower of wire clamp, the three degree of freedom of left and right, rotation, with respect to the line ball wire clamp of existing disome brass formula, the conductive contact resistance of this binding clip is lower, and security reliability is higher.
As can be seen here, this elastic connecting wire clamp have production cost low, lightweight, conduct electricity very well, good weatherability, folding dress is convenient, contribute to improve the safe operation reliability of product in supply line, can guarantee workmen's manual manipulation installation wiring on electric pole, be the electrical connection product that a kind of coefficient of safety is higher.
The technical indicator of its product is:
Applicable temperature :-40C °～+ 70C °;
Applicable voltage: 12kV～0.4kV;
Applicable electric current: be less than 200A;
Connect wire intensity: when active force to apply≤30kg of connected wire, wire non-displacement;
