Description

Technical Field

[0001] The invention relates to the technical field of power wiring, and in particular to a wire clamp for fastening electric wires. Background Art

[0002] The wire clamp is an electrical device used to connect conductors. The bolted parallel groove wire clamp adopts a plate-plate structure and is made of aluminum alloy. The connection is completed by fixing the connected conductors in the upper and lower grooved clamps by the tightening pressure of the bolts, and then the pressure is transmitted through flat washers and spring washers to provide a relatively uniform and constant pressure to the connected conductors. It can be disassembled after installation and is often used in the jumper or ground wire overlap at the tension end of the line. In order to ensure that the wire clamp has sufficient and uniform pressure on the conductor, the parallel groove wire clamp generally adopts a two-bolt or three-bolt structure. At the same time, it is required to tighten each bolt evenly during installation.

[0003] This type of wire clamp cannot withstand the tension of the wire. When tension occurs in the wire, the clamping force of the wire is completely borne by the wire clamp plate. In the long run, the connection part will become loose and stress relaxation will occur in the connection part, affecting the conductive connection effect and the reliability of the connection. Based on this, a wire clamp for tightening is proposed. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Example, see Figures 1 to 7 A wire clamp for fastening wires, comprising a wire accumulator and a wire clamp body 1 arranged at both ends of the wire accumulator, the wire clamp body 1 is made of a metal conductive material, a power storage protection module and a clamping and locking module are arranged on both sides of the wire clamp body 1, and a tightening linkage module for controlling the power storage protection module and the clamping and locking module is arranged at the center of the wire clamp body 1;

[0032] The wire accumulator includes a connecting and fixing plate 2 fixedly connected to the wire clamp main body 1 on both sides, and a torsion resistance member is connected in the middle of the connecting and fixing plate 2 through a torsion assembly. Furthermore, the torsion assembly includes a torsion connecting seat 13 arranged on the connecting and fixing plate 2, and a torsion shaft 14 located in the torsion connecting seat 13 is fixedly connected at the center position of the force storage side plate 4, a torsion spring is arranged at the connecting part between the torsion shaft 14 and the torsion connecting seat 13, and a blocking block 15 is arranged on the connecting and fixing plate 2 for limiting the movement of the force storage side plate 4.

[0033] The torque resistance member includes a resistance wheel 3 and a force storage side plate 4 arranged on both sides of the resistance wheel 3 and connected to the resistance wheel 3 through a rotating shaft;

[0034] The force storage protection module includes a telescopic opening provided in the wire clamp body 1, and the inner wall of the telescopic opening is connected to a force storage sleeve 5 via a spring return member;

[0035] Furthermore, the spring return member includes a spring resistance ring 16 fixedly connected to the outer wall of the force storage sleeve 5, and the inner wall of the telescopic opening is slidably connected with a plurality of T-shaped guide pillars 17 connected to the spring resistance ring 16, and the T-shaped guide pillars 17 are sleeved with resistance springs connected to the inner wall of the telescopic opening.

[0036] It should be noted that the spring abutment ring 16 is arranged outside the telescopic opening, and is elastically connected to the telescopic opening through the T-shaped guide column 17. Under this effect, the resetting effect of the force storage sleeve 5 can be met.

[0037] The power storage sleeve 5 is provided with a reinforcing conductive rib 6 for increasing the contact portion with the electric wire, and an extrusion component is provided on the outer side wall of the power storage sleeve 5;

[0038] A rectangular opening is provided on the power storage sleeve 5 for installing the reinforcing conductive rib 6 . The reinforcing conductive rib 6 is located in the rectangular opening, and the reinforcing conductive rib 6 and the threaded strip 21 are alternately arranged.

[0039] Furthermore, the extrusion assembly includes an engaging outer sleeve 18 meshingly connected to the linkage gear 12, and the inner wall of the engaging outer sleeve 18 is connected to two threaded ring bodies 20 with opposite spiral directions through a sliding key bar 19, and the power storage sleeve 5 is provided with a threaded strip 21 threadedly connected to the threaded ring body 20, wherein the thread on the threaded strip 21 is provided with two types of threads, and the spiral directions are arranged in opposite directions.

[0040] The inner wall of the meshing outer sleeve 18 is provided with a through sliding groove for the sliding key bar 19 to move. Through the arrangement of the power storage sleeve 5, it can meet the requirement that under the action of the linkage gear 12, the power storage sleeve 5 rotates and the threaded ring body 20 inside it is rotated at the same time, so that the threaded ring bodies 20 originally on both sides move to the middle under the action of the rotation of the thread.

[0041] A further advantage of adopting the above method is that the threaded ring bodies 20 originally sleeved on both sides of the energy storage sleeve 5 are moved toward the middle under the rotation of the linkage gear 12. During the movement, the inclined reinforced conductive ribs 6 on the outer walls on both sides are squeezed to move, so that the reinforced conductive ribs 6 are used to contact and squeeze the wires in the energy storage sleeve 5, thereby improving the conductive effect by reinforcing the conductive ribs 6.

[0042] By setting two relatively arranged wire clamp bodies 1 and arranging a wire accumulator between the wire clamp bodies 1, the wire is bent and pulled, and the required wire ends are fixed by means of a clamping and locking module, and the middle section is protected by a force storage protection module. When the wire is subjected to force, the force storage protection module of the middle section can be extended and retracted, and energy is dissipated by the wire accumulator, thereby avoiding direct traction on the clamping and locking module, thereby ensuring that the wire clamp body 1 continuously tightens the wire.

[0043] The clamping and locking module includes a fastening opening opened in the wire clamp body 1, and a plurality of nut rings 7 are rotatably arranged on the inner side wall of the fastening opening. The nut ring 7 is threadedly connected with a fastening stud 8, and a semicircular fastening ring 9 is fixedly connected to the end of the fastening stud 8. Two groups of semicircular fastening rings 9 are arranged horizontally and vertically without affecting each other, thereby ensuring effective clamping of the wires therein.

[0044] A bevel gear 26 is fixedly connected to the bottom of the nut ring 7, and a transmission ring 23 is connected to the fastening opening through a rotating ring 22. The rotating ring 22 is connected to the inner wall of the fastening opening through a support, and is rotatably connected to the transmission ring 23 through a bearing. An outer tooth ring meshing with the linkage gear 12 is provided on the outer side wall of the transmission ring 23, and helical tooth grooves meshing with the bevel gear 26 are provided on both sides;

[0045] Under the action of the linkage gear 12, the transmission ring 23 under the meshing of the outer gear ring will rotate, and the beveled tooth grooves arranged on both sides of the transmission ring 23 will drive the bevel gear 26 to rotate during the rotation process, thereby driving the nut ring 7 to rotate, so as to bring the two semicircular fastening rings 9 connected by the fastening studs 8 closer to each other, so as to effectively clamp the wires therein and effectively fix the wires.

[0046] By setting the force storage protection module in close contact with the wires, and by setting the reinforced conductive ribs 6 inside the force storage protection module in close contact with the wires, the generated pulling force is pulled through the joint action of the spring contact ring 16 and the wire accumulator, thereby effectively ensuring the contact effect with the wires and ensuring the reliability of the wiring.

[0047] The tightening linkage module includes a threaded seat 10 arranged on the wire clamp body 1, the threaded seat 10 is threadedly connected with a control stud 11, the control stud 11 is connected to a linkage gear 12 through a keyway connector, the keyway connector includes an adapter keyway opened at the end of the control stud 11, the linkage gear 12 is connected to the wire clamp body 1 through a horizontal rotating shaft 24, and a matching key strip 25 adapted to the adapter keyway is provided at one end of the horizontal rotating shaft 24.

[0048] The end of the control stud 11 is provided with multiple edges, which is convenient for operation with tools and installation by construction workers. Through the arrangement of the threaded seat 10 and the control stud 11, a locking effect can be achieved through a threaded connection, and a displacement compensation effect can be achieved through a keyway connector.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
