Description

Technical Field

[0001] The invention relates to the technical field of cable connection hardware, and more specifically to an improved hardware for copper busbar transfer cables. Background Art

[0002] Iron or aluminum metal accessories widely used in hardware transmission lines are collectively referred to as hardware. Most hardware needs to withstand large tensile forces during operation, and some also need to ensure good electrical contact. Copper busbars are also called copper busbars. Copper busbars are indispensable conductive materials for manufacturing motor windings, high and low voltage electrical appliances, switch contacts, and wires for power distribution installation. Copper busbars are a major variety of copper processing materials. Copper busbars have high mechanical properties, good electrical conductivity, thermal conductivity, excellent corrosion resistance, electroplating, brazing, beautiful metallic luster and good forming and processing performance, so various power transmission and transformation, electrical equipment, etc. made of it have been widely used in the power field. In recent years, with the sustained and rapid development of the national economy, the production and consumption of copper busbars in my country have also increased significantly. At the same time, the quality requirements for copper busbars are also constantly increasing. In actual use, users often connect cables to copper busbars, but in this process, users will use bull noses as connectors, which makes it easier to install cables on the copper busbars, thereby avoiding the situation where the cables are easily dropped when installed directly on the copper busbars, further improving the safety of the device.

[0003] In actual situations, since the bull nose is easily squeezed and thus moves inward, the staff will use additional tools to squeeze the bull nose so that the cable can be fixed on the bull nose, thereby preventing the cable from falling off the bull nose. The staff then installs the bull nose on the copper bus, but the existing installation method is cumbersome and inconvenient for the staff to operate. At the same time, there is no protective structure at the connection between the existing bull nose and the cable, which can easily cause dust and foreign matter to adhere between the cable and the bull nose, further causing a short circuit in the cable, thereby affecting the service life of the cable and the bull nose, and further increasing the probability of electrical accidents in other equipment.

[0004] Therefore, we propose an improved copper busbar adapter cable hardware to solve the above problems. Summary of the invention

[0046] At the same time, a rubber ring 6 is fixedly connected to the inner wall of the fixing ring 2, and an anti-slip ring 7 is fixedly connected to the inner wall of the rubber ring 6. At the same time, the material of the anti-slip ring 7 is silicone material, and with the assistance of the rubber ring 6 and the anti-slip ring 7, the stability of the fixing ring 2 can be made more stable, thereby avoiding the fixing ring 2 from moving on the copper nose 1, and further enabling the device to be used normally.

[0047] At the same time, a connecting ring 5 is fixedly connected to the fixing ring 2, and the connecting ring 5 is located below the fixing ring 2, and a supporting ring 8 is fixedly connected to the lower end of the connecting ring 5, and an extrusion airbag 9 is fixedly connected to the upper end of the supporting ring 8, and the supporting ring 8 has the function of supporting the extrusion airbag 9, so that the extrusion airbag 9 can be used normally, and at the same time, a plurality of air pipes 10 are connected to the output end of the extrusion airbag 9, and the plurality of air pipes 10 are all bent, and the material of the plurality of air pipes 10 are all hard plastic tubes, and when the extrusion airbag 9 is squeezed, the gas in the extrusion airbag 9 can be discharged from the air pipe 10 to a suitable position.

[0048] At the same time, the lower end of the connecting ring 5 is fixedly connected with an extension tube 11, and the extension tube 11 is made of plastic and has a certain softness. At the same time, one end of the extension tube 11 can extend to the cable, thereby protecting the connection between the cable and the copper nose 1, further preventing dust and impurities from entering the connection between the copper nose 1 and the cable, and further preventing the cable from short-circuiting.

[0049] At the same time, a blocking ring 12 is fixedly connected to the inner wall of the extension tube 11, and the blocking ring 12 is essentially an expandable air bag ring. At the same time, one end of the multiple air pipes 10 is respectively connected to the air inlet end of one of the blocking rings 12, so that the gas in the squeezed air bag 9 can be normally transported to the air pipe 10, so that the blocking ring 12 can expand accordingly, and further the blocking ring 12 can fit tightly against the cable, thereby further preventing the entry of dust and impurities.

[0050] At the same time, the device is provided with multiple blocking rings 12, and connecting pipes 13 are provided between the multiple blocking rings 12. The connecting pipes 13 are composed of hard hollow tubes, and the connecting pipes 13 serve the purpose of connecting the various blocking rings 12, and further enable all the blocking rings 12 to expand normally, so that the device can be used normally.

[0051] Meanwhile, a sealing ring 14 is fixedly connected to the inner wall of the blocking ring 12, and the sealing ring 14 can improve the sealing performance of the blocking ring 12. Meanwhile, the sealing ring 14 is made of silicone, which can further enable the sealing ring 14 to fit on the cable, thereby improving the overall sealing performance of the device and indirectly extending the service life of the device.

[0052] The same extrusion sleeve 4 is threadedly connected to the multiple extrusion blocks 3, and when the extrusion sleeve 4 is threadedly connected to the extrusion block 3, the extrusion block 3 can be squeezed, thereby fixing the cable and the copper nose 1. Before use, the user can first put the extrusion sleeve 4 on the copper nose 1, and then put the fixing ring 2 and the extrusion block 3 on the copper nose 1. At this time, the user rotates the extrusion sleeve 4, so that the device can be used normally. At the same time, when the extrusion sleeve 4 moves downward, the extrusion airbag 9 can be squeezed accordingly, so that the gas in the extrusion airbag 9 can be discharged normally to the appropriate position.

[0053] At the same time, the upper end of the extrusion sleeve 4 is fixedly connected to a limiting ring 15, wherein the limiting ring 15 is located at the connection between the extrusion sleeve 4 and the extrusion block 3, thereby preventing dust and impurities from entering the connection between the extrusion sleeve 4 and the extrusion block 3, and also serving the purpose of limiting the extrusion sleeve 4, thereby preventing the extrusion sleeve 4 from moving downward all the time.

[0054] At the same time, the upper end of the limit ring 15 is fixedly connected to the limit sleeve 16, and the limit sleeve 16 is made of rubber, and the limit sleeve 16 can fit on the copper nose 1. At the same time, the upper end of the limit sleeve 16 is fixedly connected to the extension tube 17, and the extension tube 17 also fits on the copper nose 1. At the same time, the limit sleeve 16 and the extension tube 17 both play a role in isolating dust, and can also protect the copper nose 1, thereby extending the service life of the copper nose 1.

[0055] At the same time, a plurality of magnetic blocks 18 are provided in the limiting sleeve 16, and the plurality of magnetic blocks 18 are grouped in pairs, and the magnetic poles of a group of magnetic blocks 18 are opposite. Therefore, when the limiting sleeve 16 is sleeved on the copper nose 1, with the assistance of two symmetrical magnetic blocks 18, the limiting sleeve 16 can be tightly fitted on the copper nose 1, and the extension tube 17 can lengthen the distance that dust can enter, further increasing the protection of the device, thereby extending the service life of the device.

[0056] At the same time, a rotating ring 19 is fixedly connected to the side wall of the extrusion sleeve 4, and a plurality of rotating knobs 20 are fixedly connected to the side wall of the rotating ring 19, and a rubber sleeve 21 is sleeved on the plurality of rotating knobs 20, which further facilitates the user to rotate the rotating ring 19. At the same time, with the assistance of the rotating knob 20 and the rubber sleeve 21, the user can rotate the extrusion sleeve 4, thereby facilitating the user to use the device, and indirectly improving the practicability of the device.

[0057] At the same time, through holes are penetrated on the side walls of the multiple extrusion blocks 3, and protrusions 22 are provided in the through holes. The protrusions 22 are made of iron and can move in the through holes. Multiple threaded holes 23 are provided on the side walls of the extrusion sleeve 4, and the multiple threaded holes 23 are respectively located on one side of the multiple through holes, and the multiple threaded holes 23 are threadedly connected with rotating blocks 24. The user can use a smaller screw to rotate the rotating block 24, so that the rotating block 24 can move in the thread direction of the threaded hole, so that the rotating block 24 can push the protrusion 22, and the protrusion 22 can squeeze the copper nose 1, so that the connection between the cable and the copper nose 1 can be more stable. At the same time, the end of the rotating block 24 is magnetic. During use, if the user accidentally brings out the protrusion 22, other tools can be used to put the protrusion 22 back into the through hole, so that the device can be used normally.

[0058] In the present invention, when the user needs to use this device, the user first puts the extrusion sleeve 4 on the copper nose 1, and then puts the fixing ring and the extrusion block 3 on the copper nose. At the same time, the user passes the cable through the middle of the fixing ring and the extrusion block 3, and at the same time, the user inserts the cable into the copper nose 1 and adjusts the cable to a suitable position.

[0059] After that, the user rotates and moves downward while rotating the extrusion sleeve 4. Since the extrusion sleeve 4 and the extrusion block 3 are threadedly connected, the extrusion block 3 can be further squeezed. When the extrusion block 3 is squeezed, the copper nose 1 can be squeezed. When the copper nose is squeezed, the copper nose 1 can fit tightly against the cable, thereby achieving the purpose of fixing the cable. It is particularly noteworthy that all components in this device are made of insulating materials, thereby ensuring the normal use of the copper nose 1 and the cable.

[0060] At the same time, when the extrusion sleeve 4 moves downward, the extrusion airbag 9 can be squeezed. When the extrusion airbag 9 is squeezed, the gas in the extrusion airbag 9 will be transported to the blocking ring 12 through the trachea 10, and the blocking ring 12 can expand, so that the sealing ring 14 on the blocking ring 12 can fit tightly on the cable, thereby achieving the purpose of sealing the cable.

[0061] At the same time, when the extrusion sleeve 4 moves downward, the limiting sleeve 16 and the extension tube 17 can be in a suitable position, and the magnetic block 18 on the limiting sleeve 16 can make the limiting sleeve 16 fit tightly on the cable due to its own characteristics, and further prevent dust from entering the connection between the extrusion block 3 and the extrusion sleeve 4. In this process, the limiting ring 15 can fit at the connection between the extrusion block 3 and the extrusion sleeve 4, thereby preventing dust from entering the inside of the device.

[0062] At the same time, the user can use a smaller screw to rotate the rotating block 24. With the assistance of the threaded hole, the rotating block 24 can be moved forward, and further the rotating block 24 can enter the protrusion 22. The protrusion 22 can be squeezed by the rotating block 24, so that the copper nose 1 can be squeezed accordingly, and further the connectivity between the copper nose 1 and the cable can be better, thereby avoiding the cable from detaching, further facilitating the user to install the cable and the copper nose 1, thereby facilitating the user's work and indirectly improving the user's work efficiency.
