Description

Technical Field

[0001] The invention relates to the technical field of cable connection devices, in particular to a cable capable of enhancing connection effects. Background Art

[0002] With the rapid development of the power and communication fields, cables, as key equipment for transmitting power and signals, have been widely used in various projects, especially in the fields of industry, construction, transportation, etc. The demand for the use of cables is increasing, and the wiring quality of cables has an important impact on their use effect and safety. However, existing cables have certain problems in the wiring process, such as poor contact, oxidation corrosion, increased contact resistance, etc., which may lead to a series of problems such as unstable current transmission, signal interference, system failure, etc. Therefore, how to improve the cable wiring effect and ensure the long-term stable operation of the cable after wiring has become an important topic in the development of cable technology.

[0003] After searching, it was found that the prior art publication number is CN216355177U, which discloses a cable head insulating glue reinforced cable, including a terminal, asphalt glue, a pressure hole, a sealing cover and a sealing tube. The bottom of the terminal is fixedly connected to the top of the sealing tube, the bottom of the sealing tube is fixedly connected to the top of the sealing cover, the inner wall of the sealing tube is fixedly connected to the surface of the asphalt glue, the left side of the sealing tube is fixedly connected to the surface of the pressure hole, and the left side of the pressure hole is movably connected with a sealing strip. This scheme seals the left side of the pressure hole by setting a sealing strip, and then conveniently fixes and limits the surface of the sealing strip by a convenient fixing component, thereby enhancing the sealing effect of the sealing strip and solving the problem that the sealing effect of the existing sealing end cover is poor. At the same time, it is not convenient for the staff to install and disassemble, resulting in the through hole being easily corroded together with the asphalt sealant in the cable. The problem of reducing the sealing effect of the insulating glue on the reinforced cable is achieved, and the effect of easy installation is achieved.

[0004] Therefore, based on the above search and combined with the existing technology, the above scheme relies on the sealing effect of the sealing strip and its contact surface with the pressurized hole. However, if the material or installation of the sealing strip is improper, leakage may still occur, and it cannot completely prevent the infiltration of moisture or contaminants, affecting the long-term use of the cable. At the same time, if the connection between the cable and the terminal is improper, the contact surface will be uneven or the contact area will be insufficient, thereby increasing the contact resistance. During long-term use, the connection points with poor contact will be affected by mechanical stress, which may cause the terminal or cable to be damaged or even broken. For this reason, we propose a cable that can enhance the wiring effect. Summary of the invention

The specific shape is an existing mature technology and will not be elaborated here. The end of the isolation plate 101 away from the movable ratchet 2 is fixedly connected with an extension sleeve 102 by bolts. When in use, when the two contact tubes 107 are connected to each other, in order to avoid a gap between the two contact tubes 107 after the connection, and to avoid oxidation of the outer surface of the contact tube 107, a coating device capable of improving the conductivity of the contact tube 107 is provided between the extension sleeve 102 and the isolation plate 101. Then, when fixing the cable 4, in order to further improve its stability and at the same time have good conductive properties, the inner end of the outer tube 6 is provided with a clamping device capable of improving the connection stability of the cable 4.

[0036] See also Figure 2 - Figure 5The smearing device includes a support ring 106, which is sleeved on the outer surface of the expansion sleeve 102, and there are two support rings 106, wherein the inner diameter of the right support ring 106 is smaller than that of the left support ring 106, thereby, the inner end of the right support ring 106 does not contact the outer surface of the expansion sleeve 102, and the inner end of the left support ring 106 contacts the outer surface of the expansion sleeve 102, and a liquid bag 103 is fixedly connected between the two support rings 106, the liquid bag 103 is in a circular ring shape, and the material is polyethylene, and the liquid bag 103 is filled with conductive oil that can improve the conductivity, the conductive oil is a mixture of conductive powder containing silver, copper or lead and lubricating oil or other organic solvents, which can reduce contact resistance, improve conductivity, and also has a certain anti-corrosion effect, and can effectively isolate the air, then the liquid bag 103 is pierced to make the conductive oil inside the bag flow out, and the outer surface of the expansion sleeve 102 is provided with a plurality of rectangular The rectangular holes are arranged in a ring shape, and a rupture block 108 capable of piercing the liquid bag 103 is rotatably installed in each of the rectangular holes, the sharp end of the rupture block 108 faces upward, and the rupture block 108 is in an inclined state and exposed for a distance. Specifically, the left and right ends of the liquid bag 103 are connected to the edges of the support ring 106, and because the inner diameter of the right support ring 106 is smaller than that of the left support ring 106, when the support ring 106 and the liquid bag 103 are sleeved on the outer surface of the expansion sleeve 102, the rupture block 108 will not directly pierce the liquid bag 103, and a guide groove 109 is provided at the left end of the rupture block 108 for facilitating the flow of conductive oil, so when the left support ring 106 moves toward the direction close to the expansion sleeve 102, the outer surface will contact the upper end of the rupture block 108, and rotate under the movement of the support ring 106 to pierce the liquid bag 103, and then the conductive oil inside flows out and drips on the outer surface of the contact tube 107;

[0037] The inner end of one of the outer rotating cylinders 1 away from the outer tube 6 is threadedly screwed with a threaded sleeve 105, and the inner end of the threaded sleeve 105 is provided with an extrusion ring 104, which corresponds to the support ring 106. Specifically, limit blocks are fixedly installed inside the two outer rotating cylinders 1, so that when the outer rotating cylinder 1 is threadedly screwed on the outer surface of the threaded sleeve 105, only half of the area of ​​the outer surface of the threaded sleeve 105 can be sleeved, and the other half of the threaded surface is sleeved by the other outer rotating cylinder 1. When the left and right outer rotating cylinders 1 are respectively threadedly screwed on the outer surfaces of the threaded sleeve 105, as the two outer rotating cylinders 1 approach each other, the left and right ends of the extrusion ring 104 will contact the support ring 106 away from the expansion sleeve 102, and as the outer rotating cylinders 1 approach each other, the extrusion ring 104 pushes the support rings 106 on the left and right sides to move away from each other, and a sealing rubber ring is fixedly sleeved inside the end of the outer rotating cylinder 1 that is close to each other to further improve the sealing performance.

[0038] like Figure 3 - Figure 5As shown, the inner end of the extension sleeve 102 is provided with two through holes, and a liquid infusion tube 304 is passed through the through holes, and the liquid infusion tube 304 is symmetrically distributed up and down, a bellows 302 is fixedly installed on the inner side of the contact tube 107, and two gas pipes 303 are fixedly connected to the outer surface of the right end of the bellows 302, and the free ends of the gas pipes 303 are both passed through the inside of the liquid infusion tube 304, and a movable rod 301 is passed through the inner end of the contact tube 107, and the left end of the movable rod 301 is fixedly connected to the right end of the bellows 302, and a rectangular hole is provided at the inner end of the contact tube 107, and a rectangular block is fixedly installed at the left end of the movable rod 301, and the rectangular block is passed through the rectangular hole. In this way, when the movable rod 301 moves left and right, the movable rod 301 is prevented from rotating. Specifically, the bellows 302 is made of rubber, and an elastic wire is embedded in the bellows 302, so that the bellows 302 can be restored to its initial state when compressed;

[0039] A clamping piece 305 is fixedly installed on the outer surface of the infusion tube 304. The clamping piece 305 is made of metal and has elasticity. A plurality of through holes are opened on the outer surface of the right support ring 106. When the infusion tube 304 passes through the through holes on the outer surface of the support ring 106, the clamping piece 305 is inserted into the support ring 106 to achieve a certain fixing effect. A sealing plate 306 is fixedly installed inside the gas pipe 303. A sliding rod is inserted inside the sealing plate 306. The sliding rod and the sealing plate 306 are connected by a sealing spring 308. A sealing cover 307 is fixedly installed on the left end of the sliding rod, and the sealing cover 307 is located on the left side of the sealing plate 306. A plurality of air holes are opened on the outer surface of the sealing plate 306. The diameter of the sealing cover 307 is smaller than the diameter of the sealing plate 306 and covers the air holes. A sealing rubber ring is sleeved on the outer surface of the sealing cover 307 to increase air tightness.

[0040] Example 2: Please refer to Figure 2 , Figure 6 - Figure 8 , a cable capable of enhancing wiring effect, based on Example 1, the clamping device comprises a support tube 202, the support tube 202 is fixedly mounted on the inner end of the outer tube 6, and the left end of the support tube 202 is fixedly welded to the right end of the contact tube 107, the support tube 202 is made of copper and has good conductivity, a center rod 208 is passed through the inner end of the support tube 202, and the center rod 208 is fixedly connected to the movable rod 301, the center rod 208 and the support tube 202 are connected through a center spring 214, a triangular pad 207 is fixedly mounted on the inner end of the outer tube 6, a passive ring 205 is sleeved on the right outer surface of the support tube 202, the passive ring 205 is made of a deformable metal material, and the triangular pad 207 corresponds to the passive ring 205, a plurality of strip holes are opened on the outer surface of the support tube 202, the strip holes are arranged in a ring shape, and bite blocks 204 are arranged inside the strip holes;

[0041] The end of the center rod 208 away from the movable rod 301 is rotatably mounted with a plurality of pull plates 209 through a latch, and the end of the pull plate 209 away from the center rod 208 is rotatably connected to the bite block 204 through a latch, the center rod 208 is made of copper, and the outer surface is in close contact with the support tube 202, and the bite block 204 and the pull plate 209 are both made of high-strength metal materials (such as copper-nickel alloy), which have good electrical conductivity and certain strength, and the outer surface of the bite block 204 is in contact with the outer surface of the triangular pad 207, the center rod 208 moves to the left, and the bite block 204 is pulled to move by the pull plate 209, and the bite block 204 is in close contact with the passive ring 202. 05 gathers toward the center of the support tube 202 under the action of contact with the slope surface of the triangular pad 207. Specifically, the end of the bite block 204 away from the triangular pad 207 is provided with a bite tooth. Then, when the cable 4 is inserted into the support tube 202, the bite block 204 is tightly fitted with the outer surface of the cable 4 through the bite teeth. The interior of the locking sleeve 5 is provided with an extrusion sleeve 206 that can push the bite block 204 to move. The extrusion sleeve 206 corresponds to the support tube 202. When the locking sleeve 5 is sleeved on the outer surface of the outer tube 6 and rotates, it can push the extrusion sleeve 206 to move toward the center rod 208 as the locking sleeve 5 moves.

[0042] The movable ratchet 2 is connected to the outer tube 6 through the return spring 203, and the movable ratchet 2 and the outer tube 6 are connected through the sealing gasket 201. The sealing gasket 201 is wrapped around the outer surface of the return spring 203, so that it can well protect the return spring 203. A ratchet ring is installed at the left end of the locking sleeve 5. When the locking sleeve 5 is threadedly screwed to the outer surface of the outer tube 6, the ratchet ring will engage with the movable ratchet 2. Then, when the locking sleeve 5 rotates, the ratchet ring and the movable ratchet 2 are engaged with each other. During each rotation, the movable ratchet 2 will move to the left and be reset again under the elastic force of the return spring 203. At this time, the locking sleeve 5 can only rotate in one direction, which increases the stability of the locking sleeve 5.

[0043] like Figure 7 - Fig. 9 As shown, the inner end of the outer tube 6 is fixedly connected with a rubber bag 210. After the rubber bag 210 is deformed by force, it can recover to the initial state by its own elastic force. The free end of the infusion tube 304 is fixedly connected with the rubber bag 210. The end of the movable ratchet 2 close to the rubber bag 210 is fixedly connected with an extension plate 213, and the left end of the extension plate 213 is fixedly connected with a passive rod 212. The passive rod 212 is located inside the rubber bag 210, and the passive rod 212 corresponds to the infusion tube 304. Then, when the rubber bag 210 is pushed by the extension plate 213, it begins to deform, so that the passive rod 212 blocks the output end of the infusion tube 304 to prevent the conductive oil inside the rubber bag 210 from flowing back. The bottom end of the rubber bag 210 is fixedly connected with a discharge pipe 211.

[0044] The locking sleeve 5 is also sleeved with a heat shrink sleeve 3 (usually made of polyolefin material, with good insulation, and adaptable to wires and components of different sizes). The left end of the heat shrink sleeve 3 is sleeved on the outer surface of the extrusion sleeve 206. When the locking sleeve 5 is tightened, the heat shrink sleeve 3 can be firmly fixed. Before the cable 4 is inserted into the support tube 202, the outer surface of the copper wire with conductive function in the cable 4 is coated with an insulating paint layer with insulating function ( Fig. 9 In order to ensure that the conductive oil can better adhere to the outer surface of the copper wire inside the cable 4 and improve the conductive performance, it is necessary to peel off the insulating paint layer on the outer surface of the copper wire, so as to achieve a better conductive effect, but only one section of the part that needs to be bitten is needed. In order to prevent the paint layer on the outer surface of the copper wire from being peeled off too much during use, so that it needs to be re-trimmed, it is only necessary to heat the heat shrink sleeve 3 to shrink it, so that the part with too much paint peeling can be completely sealed in the inner cavity of the locking sleeve 5, which makes up for the problem of needing to re-trim the length of the cable 4.

[0045] The working principle of the present invention is:

[0046] When in use, the liquid bag 103 is placed on the outer surface of the expansion sleeve 102 in the correct direction. At this time, the right end of the infusion tube 304 passes through the support ring 106 and pierces the liquid bag 103 and is inserted into the inside. Then, the peeled cable 4 is passed through the inside of the support tube 202 and moved to the left side against the center rod 208 for a distance. At this time, the movement of the center rod 208 pushes the movable rod 301 to move, and the center rod 208 squeezes the corrugated tube 302. The bellows 302 is deformed to squeeze the air inside. The squeezed air then flows into the liquid bag 103 along the air delivery pipe 303, so that the conductive oil inside the liquid bag 103 flows into the rubber bag 210 through the delivery pipe 304. As the central rod 208 moves, the bite block 204 is pulled to move through the pull plate 209, so that the copper wire in the cable 4 is initially fixed. Then, the locking sleeve 5 is rotated to gradually move toward the outer tube 6, so that the extrusion sleeve 206 pushes the bite block 204 to move again, further clamping the copper wire in the cable 4.

[0047] At the same time, as the locking sleeve 5 rotates, the ratchet ring and the movable ratchet 2 are engaged with each other, causing the movable ratchet 2 to continuously reciprocate left and right, thereby squeezing the rubber bag 210 to deform through the extension plate 213, so that the conductive oil inside the rubber bag 210 flows out through the discharge pipe 211 and fills the gap between the engaging block 204 and the copper wire, thereby increasing the conductive performance.

[0048] First, one of the outer rotating cylinders 1 is screwed onto the outer surface of the threaded sleeve 105. At this time, the left and right ends of the extrusion ring 104 will contact the support ring 106 away from the expansion sleeve 102, and as the outer rotating cylinders 1 approach each other, the support rings 106 on the left and right sides of the extrusion ring 104 move away from each other. Then, when the left support ring 106 moves toward the expansion sleeve 102, the outer surface will contact the upper end of the rupture block 108 and rotate under the movement of the support ring 106, and pierce the liquid bag 103. Then the conductive oil inside flows out and drips on the outer surface of the contact tube 107. Then, the other outer rotating cylinder 1 is screwed onto the outer surface of the threaded sleeve 105. At this time, the conductive oil is applied to the outer surfaces of the two contact tubes 107, and the conductive performance is further increased.

[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 in the present invention, which should be covered by the protection scope of the present invention.
