Description

Technical Field

[0001] The invention relates to the technical field of cable installation devices, and in particular to a cable auxiliary installation device for electromechanical construction. Background Art

[0002] The insulated piercing wire clamp is an efficient and convenient cable auxiliary installation device, which is mainly used for the installation of cable branches or connections. Its structure is mainly composed of an insulating shell, a piercing knife, a sealing gasket, waterproof silicone grease, a high-strength bolt, a torque nut and a cable terminal cap. This cable auxiliary installation device adopts a special design, so that the cable installation work can be easily realized without cutting the main cable or stripping the insulation layer of the cable during installation. It has also been widely used in the field of electromechanical construction. Its installation is simple and quick, without the need for special tools and professional skills, which reduces the difficulty and cost of construction. At the same time, this type of cable auxiliary installation device is completely insulated and can be operated with power on, which improves work efficiency. In addition, the cable auxiliary installation device is also resistant to distortion, shockproof, waterproof, and corrosion-resistant, ensuring the stability and safety of cable installation.

[0003] The working principle of this cable auxiliary installation device is to tighten the torque nut so that the puncture knife pierces the insulation layer of the cable and contacts the conductor.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] like Figures 1 to 10 As shown, an auxiliary cable installation device for electromechanical construction provided by an embodiment of the present invention includes an insulating housing 100 , a puncture assembly 200 and a clamping assembly 300 .

[0023] The insulating housing 100 includes an upper half shell 110 and a lower half shell 120, wherein an upper tool holder 130 is installed on the upper half shell 110, and a lower tool holder 140 is installed on the lower half shell 120; the upper half shell 110 and the lower half shell 120 are arranged opposite to each other, and the upper tool holder 130 and the lower tool holder 140 are provided with two mounting grooves spaced apart along a first direction, and the mounting grooves extend along a second direction for placing a main cable and a branch cable; the upper half shell 110 is plugged into the lower half shell 120, and the two can be away from or close to each other; The puncture assembly 200 includes an upper puncture knife 210 and a lower puncture knife 220, which are respectively detachably fixedly installed in the upper tool holder 130 and the lower tool holder 140 and arranged opposite to each other. The upper puncture knife 210 and the lower puncture knife 220 are both made of conductive metal. The clamping assembly 300 includes a turntable 310, a stud 320, a torque nut 330, a breaking ring 340, a locking nut 350, an anti-slip piece 360, a mounting sleeve 370 and a guide plate 380; a blind hole is provided in the middle of the upper end of the upper half shell 110, the mounting sleeve 370 is fixedly arranged in the blind hole, the guide plate 380 is fixedly connected to the top of the mounting sleeve 370, a guide groove is provided on the guide plate 380, the turntable 310 is rotatably installed on the guide plate 380 and is located above the guide plate 380; a guide column is fixedly connected to the lower surface of the turntable 310, and the guide column is slidably installed in the guide groove. The stud 320 passes through the turntable 310, the upper half shell 110 and the lower half shell 120 in sequence, and a connecting plate 321 is fixedly connected above the stud 320, and the connecting plate 321 is connected to the turntable 310 by a plurality of bolts, and the plurality of bolts are evenly distributed along the circumference of the turntable 310. The locking nut 350 is fixedly connected to the lower end of the lower half shell 120, and the locking nut 350 and the stud 320 are threadedly matched; the breaking ring 340 is fixedly connected to the upper surface of the turntable 310, and the torque nut 330 is fixedly connected to the upper end of the breaking ring 340; slots are provided in the middle of the torque nut 330 and the turntable 310; the outer periphery of the anti-slip component 360 is provided with an anti-slip layer, and the anti-slip layer is made of rubber material; the anti-slip component 360 is installed in the slot, and the upper part of the anti-slip component 360 is frictionally connected to the breaking ring 340, and the lower part is frictionally connected to the turntable 310.

[0024] During installation, the torque nut 330 is turned. Under the action of the thread, the torque nut 330 rotates and moves upward, the distance between the upper shell 110 and the lower shell 120 increases, and the main cable and the branch cable are respectively clamped in the two installation grooves. Thereafter, the torque nut 330 is turned in the opposite direction. During the rotation, the torque nut 330 moves downward. The torque nut 330 drives the breaking ring 340 and the turntable 310 to rotate and move synchronously. During the downward movement of the turntable 310, the distance between the upper shell 110 and the lower shell 120 gradually decreases, and the upper bayonet 210 and the lower bayonet 220 gradually approach the cable. After the upper bayonet 210 and the lower bayonet 220 come into contact with the insulation of the cable, as the distance between the upper half shell 110 and the lower half shell 120 decreases, the upper bayonet 210 and the lower bayonet 220 pierce the insulation of the cable. During this process, the torque gradually increases, and the shear force on the breaking ring 340 gradually increases. When the shear strength limit of the breaking ring 340 is reached, the breaking ring 340 breaks, and the installation work is completed.

[0025] Due to the friction between the anti-slip part 360 and the turntable 310, after the breaking ring 340 breaks, the breaking ring 340 and the torque nut 330 will not fall off from the upper shell 110 due to the action of the friction force, thereby solving the problem of the torque nut 330 falling off after the insulation piercing wire clamp is installed in the prior art, and improving the safety of the cable auxiliary installation device.

[0026] In a further embodiment, the anti-slip member 360 is connected to an adjustment assembly 400, and the adjustment assembly 400 is used to adjust the friction between the rotating disk 310 and the anti-slip member 360. The adjustment assembly 400 includes an adjustment bolt 410, the anti-slip member 360 is slidably installed in the slot along the axial direction, the adjustment bolt 410 is rotatably installed in the slot, and the adjustment bolt 410 is threadedly matched with the anti-slip member 360.

[0027] When adding branch cables, first rotate the adjusting bolt 410. Under the action of the thread, the anti-dropping member 360 overcomes the friction between itself and the turntable 310 and moves toward the torque nut 330. The contact area between the anti-dropping member 360 and the broken ring 340 gradually increases. At the same time, the contact area between the anti-dropping member 360 and the turntable 310 gradually decreases. The contact area between the anti-dropping member 360 and the turntable 310 is adjusted according to the required puncture force. After the adjustment is completed, the installation work is carried out. When the rotating torque overcomes the force required for the broken ring 340 to break and the friction between the turntable 310 and the anti-dropping member 360, the broken ring 340 breaks. After the broken ring 340 breaks, the upper part of the anti-dropping member 360 is still frictionally connected with the broken ring 340, and the lower part of the anti-dropping member 360 is still frictionally connected with the turntable 310, thereby ensuring that the torque nut 330 will not fall after the installation is completed.

[0028] During the puncture process, the puncture force provided by the present invention is positively correlated with the contact area between the turntable 310 and the anti-slip member 360. When the force required to puncture the insulating layer is greater, the force required when the breaking ring 340 breaks needs to be increased, and the friction between the turntable 310 and the anti-slip member 360 needs to be increased. In order to achieve the purpose, the contact area between the anti-slip member 360 and the turntable 310 needs to be increased, and the angle of the adjusting bolt 410 needs to be reduced. When installing different cables, the present invention does not need to replace the torque nut 330. The adjusting bolt 410 is rotated according to the demand to change the friction between the anti-slip member 360 and the turntable 310, thereby changing the puncture force provided, thereby improving the universality of the cable auxiliary installation device.

[0029] In a further embodiment, the upper bayonet 210 is rotatably mounted on the upper tool seat 130, and the lower bayonet 220 is rotatably mounted on the lower tool seat 140; the upper bayonet 210 and the lower bayonet 220 are both fixedly connected with an adjusting wheel 230; a limiting assembly 500 is arranged between the upper bayonet 210 and the upper tool seat 130, and a limiting assembly 500 is arranged between the lower bayonet 220 and the lower tool seat 140, and the limiting assembly 500 is used to limit the rotation of the corresponding adjusting wheel 230. The limiting assembly 500 includes a ratchet 510, a ratchet tooth 520 and a limiting spring 530; the ratchet 510 is fixedly connected to the adjusting wheel 230, and the upper tool seat 130 and the lower tool seat 140 are both equipped with a moving seat 150; the moving seat 150 extends in the vertical direction and is connected to the upper tool seat 130 for sliding up and down, and the limiting column 160 is connected to the moving seat 150 for moving up and down; the ratchet 520 is fixedly connected to one end of the limiting column 160 facing the ratchet 510; the two ends of the limiting spring 530 are respectively connected to the moving seat 150 and the limiting column 160, and the limiting spring 530 makes the ratchet 520 tend to engage with the ratchet 510.

[0030] In the initial state, the ratchet 520 and the ratchet wheel 510 are meshed, the adjusting wheel 230 is in a stationary state, and the upper piercing knife 210 and the lower piercing knife 220 are both in a horizontal state. When the main cable and the branch cable have the same wire diameter, they can be directly installed.

[0031] When the wire diameter of the branch cable is smaller than that of the main cable, the two adjusting wheels 230 are rotated to make the upper bayonet 210 and the lower bayonet 220 both inclined, and the greater the difference in wire diameter between the main cable and the branch cable, the greater the inclination of the upper bayonet 210 and the lower bayonet 220; during the rotation of the adjusting wheel 230, the teeth on the ratchet wheel 510 push the ratchet teeth 520 to move vertically away from the ratchet wheel 510, and the ratchet wheels 510 and the ratchet teeth 520 are in a non-engaged state. While the cam 20 moves vertically, the limit column 160 moves synchronously with the ratchet 520, and the limit spring 530 accumulates force; when the ratchet 520 passes over the teeth on the ratchet wheel 510, the ratchet 520 and the limit column 160 are no longer subjected to thrust, and the limit spring 530 is released. The limit spring 530 pushes the limit column 160 and the ratchet 520 to move toward the ratchet wheel 510, and the ratchet wheel 510 and the ratchet 520 are in meshing state again; the above process is repeated until the angle adjustment is completed.

[0032] When the angle adjustment of the upper bayonet 210 or the lower bayonet 220 is completed, the limit spring 530 is in a natural state, and the ratchet 510 and the ratchet teeth 520 are in an engaged state, thereby limiting the reverse rotation of the ratchet 510. Then the angles of the upper bayonet 210 and the lower bayonet 220 remain unchanged, and then they are installed.

[0033] In a further embodiment, at least two groups of upper tool seats 130 and lower tool seats 140 are provided, and the two groups of upper tool seats 130 are spaced apart along the second direction, thereby ensuring the stability of power transmission.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
