Description

Technical Field

[0001] The invention relates to the technical field of cables, in particular to an oil-resistant fluoroplastic integrated sheathed cable device. Background Art

[0002] Cable is a wire product used to transmit electrical energy, electrical signals or realize electromagnetic energy conversion. It consists of one or more mutually insulated conductors and an outer insulating protective layer and a protective sheath. In order to improve the oil resistance of the cable, an integrated sheath made of fluoroplastic is usually provided on the cable to make it have good oil resistance, can resist the erosion of various oil substances, is not easily penetrated and corroded by oil, and can work stably for a long time in an oily environment.

[0003] When traditional cables are used and break in the external environment and need to be repaired, they are often connected by crimping a tube with a heat shrink tubing, or by welding the core joints. However, during the crimping process, it is easy to cause problems such as incomplete crimping or excessive crimping, which may damage the core. It is also inconvenient to disassemble, which affects subsequent modifications. It is also difficult to quickly put on the heat shrink tubing, which is inefficient. It is difficult to keep the two cores aligned when welding, and the operation process is cumbersome and difficult to disassemble, which is inconvenient for subsequent repairs. At the same time, high temperature can easily damage the insulation layer, which has poor practicality. When cables need to be suspended or isolated from the ground during installation, they are often suspended by rolling belts or placed directly on buildings or supports. After the rolling belts are fixed, it is difficult to adjust the position of the cables. Moreover, when they are directly placed on buildings or supports, friction easily causes cable wear, which is not practical. To ensure the sealing of the cable end interface, sealing tape is often used in combination with a heat shrink sleeve. However, the tape needs to be repeatedly wrapped during the operation, resulting in low operating efficiency and poor sealing effect. Summary of the Invention

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 2 、 Figure 6-Figure 7As shown, the oil-resistant fluoroplastic integrated sheath cable device of the present invention includes an outer sheath 1, a main structure 2 arranged inside the outer sheath 1, a docking structure 5 connected to the main structure 2, and a protective structure 6 matched with the docking structure 5; the main structure 2 includes a conductor 205, and three conductors 205 are provided inside the two sections of the outer sheath 1. The inner walls of the two sections of the outer sheath 1 are both bonded with a shielding layer 201, and the inner walls of the shielding layer 201 are bonded with an inner lining layer 202. At this time, the ends of the inner lining layer 202 and the filler 203 simultaneously abut against the second insulating sleeve 50. 2. The three insulating layers 204 respectively contact the three second guide sleeves 505. The inner circumferential array of the inner lining layer 202 has three insulating layers 204. The inner wall of the insulating layer 204 is fitted with a conductor 205. The outer wall of the insulating layer 204 and the inner wall of the inner lining layer 202 are in contact with a filler 203. The end faces of the inner lining layer 202 and the filler 203 contact the second insulating sleeve 502. The end face of the insulating layer 204 contacts the second guide sleeve 505. The end of the insulating layer 204 is slidably connected to the second insulating sleeve 502, forming the main body of the cable, which is highly practical.

[0023] Specifically, such as Figure 3 and Figure 5-Figure 7As shown, when the cable is broken and needs to be reconnected, it is only necessary to cut off the irregular parts at both ends of the break, peel off the outer sheaths 1 and the insulating layer 204 at both ends, and expose the conductor 205. The docking structure 5 includes a first insulating sleeve 501 and a second insulating sleeve 502 slidingly connected to the first insulating sleeve 501. A first insulating sleeve 501 is provided between the two sections of the outer sheath 1, and a spring 503 is fixedly connected between the first insulating sleeve 501 and the second insulating sleeve 502. Since the first insulating sleeve 501 and the second insulating sleeve 502 and the first guide sleeve 504 and the second guide sleeve 505 are slidingly connected, and the first insulating sleeve 501 and the second guide sleeve 505 are slidingly connected, the first insulating sleeve 501 and the second insulating sleeve 502 are slidingly connected. A spring 503 is installed between the two insulating sleeves 502, which makes it easy to adapt to the fracture spacing of different lengths by adjusting the overlap size of the first insulating sleeve 501 and the second insulating sleeve 502, which is highly practical. Three first guide sleeves 504 are provided inside the first insulating sleeve 501, and three second guide sleeves 505 are provided at the corresponding positions of the second insulating sleeve 502. The first guide sleeve 504 and the second guide sleeve 505 are slidably connected. The insides of the first guide sleeve 504 and the second guide sleeve 505 are both clamped with conductors 205. Three screws 506 are threadedly connected on the first insulating sleeve 501 and the second insulating sleeve 502. The six screws 506 respectively interfere with the first guide sleeve 504 and the second guide sleeve 505 at the corresponding position, and the end of the screw 506 interferes with the conductor 205. The cross-sections of the first insulating sleeve 501 and the second insulating sleeve 502 are both "concave" shaped structures, and the cross-section of the first guide sleeve 504 is "T" shaped. The three screws 506 located at the same end are arranged in a circular array. Then, the integral part composed of the first insulating sleeve 501 and the second insulating sleeve 502 is placed between the two sections of the outer sheath 1, so that the end of the second insulating sleeve 502 is aligned with the three adjacent conductors 205, and the three conductors 205 are engaged with the three second guide sleeves. 505, and then screw the three screws 506 on the second insulating sleeve 502 so that the ends of the screws 506 are pressed against the conductor 205, thereby achieving the fixation of the conductor 205 and the second guide sleeve 505. At this time, the second insulating sleeve 502, the second guide sleeve 505 and the conductor 205 at the corresponding position are fixed as a whole through the screws 506. Then repeat the same operation to fix the three conductors 205 of the other section on the first guide sleeve 504 in the first insulating sleeve 501 respectively, and use the other three screws 506 to fix them. At this time, the connection of the two broken cable sections is completed, the operation is efficient and flexible, and it is convenient for later disassembly and modification.

[0024] Specifically, such as Figure 2-Figure 4 and Figure 7As shown, the outer wall of the second insulating sleeve 502 is equipped with a protective structure 6, which includes a second mounting belt 601 and second bolts 602 provided at both ends of the second mounting belt 601. Two second mounting belts 601 are provided between the two sections of the outer sleeve 1. A third mounting belt 603 is provided on the symmetrical surface of the second mounting belt 601. The second mounting belt 601 and the third mounting belt 603 are fixedly connected by a second bolt 602. A protective sleeve 605 is fixedly connected between the two second mounting belts 601 and the two third mounting belts 603. The inner sides of the second mounting belt 601 and the third mounting belt 603 are both engaged with a rubber frame 604. At the same time, the rubber frames 604 on the inner sides of the second mounting belt 601 and the third mounting belt 603 are in contact with the outer wall of the shielding layer 201, ensuring the overall sealing, preventing water or oil from entering the internal cavity from the gap, and having strong anti-oil pollution ability. The two pairs of rubber frames 604 are in contact with each other between the ends of the two sections of the shielding layer 201 respectively. One of the protective sleeves 605 is fixedly connected to two rubber strips 607, and the other protective sleeve 605 is provided with two jacks 607. 8. The rubber strip 607 is engaged with the socket 608 at the corresponding position. During the process of tightening the second bolt 602, the rubber strip 607 is inserted into the socket 608, which solves the problem of the gap between the two protective sleeves 605. The shielding pads 606 on the inner side of the two protective sleeves 605 are pressed against the outer wall of the second insulating sleeve 502. The inner side surfaces of the two protective sleeves 605 are fixedly connected with the shielding pads 606. The rubber strip 607 is fixedly connected to the adjacent shielding pads 606. The two shielding pads 606 conflict with each other. The inner side of the shielding pads 606 The side surface contacts the second insulating sleeve 502. After the two sections of cable are re-connected, a pair of second mounting belts 601 and a protective sleeve 605 between the two are respectively wrapped around one side of the second insulating sleeve 502. At the same time, a pair of third mounting belts 603 and a protective sleeve 605 between the two are wrapped around the other side of the second insulating sleeve 502. The two protective sleeves 605 form a cylindrical structure, and the second mounting belt 601 and the adjacent third mounting belt 603 are locked by a second bolt 602. At this time, the two protective sleeves 605 effectively protect the internal connection.

[0025] Specifically, such as Figure 1 and Figure 10As shown, a sealing structure 3 is installed at the end of the outer sheath 1, and the sealing structure 3 includes a rubber sleeve 301 and two first rotating shafts 302 fixedly connected to the side of the rubber sleeve 301. The rubber sleeve 301 is engaged with the end of one section of the outer sheath 1. The conductor 205 is passed through the holes reserved in the center of the rubber sleeve 301. The rubber sleeve 301 is aligned with the end of the cable so that the three conductors 205 pass through the three holes in the center of the rubber sleeve 301 respectively. At this time, the outer wall of the outer sheath 1 and the inner wall of the rubber sleeve 301 are in contact with each other, and the conductors 205 and the inner walls of the holes are in contact with each other, ensuring the overall sealing of the cable and preventing oil or water from entering the internal space from the end of the cable. The end of the conductor 205 is fixedly connected to a joint 305. A fixing ring 303 is rotatably connected to each of the two first rotating shafts 302. The inner side of the fixing ring 303 contacts the outer sheath 1. The two fixing rings 303 are fixedly connected by a first bolt 304. Then rotate the two fixing rings 303 around the first rotating shaft 302 until the ends of the two are in contact with each other, and then use the first bolt 304 to fix the two fixing rings 303. At this time, the installation of the rubber sleeve 301 is completed, which effectively ensures the sealing performance, is easy to install, and has strong firmness. Finally, the three connectors 305 are fixed to the ends of the conductor 205 respectively by crimping and fitting with the heat shrink sleeve, which is easy to operate.

[0026] Specifically, such as Figure 1 、 Figure 8 and Figure 9As shown, a hook structure 4 is connected to the outer wall of the outer sheath 1, and the hook structure 4 includes a first mounting belt 401 and a knob 402 rotatably connected to the first mounting belt 401. The outer wall of the outer sheath 1 is slidably connected to the first mounting belt 401, and the inner sliding connection of the first mounting belt 401 is a limited block 403, and the limit block 403 is slidably connected to the knob 402. The limit block 403 contacts the first mounting belt 401. When the cable needs to be suspended or isolated from the ground and hung on a building or a bracket, , just insert the hexagonal wrench into the driving hole on the knob 402, and then turn the hexagonal wrench, so that the knob 402 rotates inside the first mounting belt 401, and slides the limit block 403 to the outside. At this time, the position of the first mounting belt 401 on the cable can be adjusted at will, and multiple identical first mounting belts 401 can be set at different positions on the cable, which is beneficial to the overall overhead of the cable and improves the stability of the cable. After adjusting the multiple first mounting belts 401 to the appropriate position, turn the hexagonal wrench in the opposite direction to rotate them. The button 402 drives the limit block 403 to press against the outer sheath 1, thereby limiting the position of the first installation belt 401 and improving the firmness. Then, the first installation belt 401 is fixedly connected to the second rotating shaft 404, and the second rotating shaft 404 is rotatably connected to the first rotating bar 405. The first rotating bar 405 is slidably connected to the first installation belt 401, and the first rotating bar 405 is fixedly connected to the third rotating shaft 406. The third rotating shaft 406 is rotatably connected to the second rotating bar 407. The second rotating bar 407 is rotatably connected to the first rotating bar 407. The bars 405 are slidingly connected. Insert your finger into the groove reserved on the first turning bar 405 and press the second turning bar 407 outward, thereby driving the second turning bar 407 to rotate 90 degrees around the third rotation axis 406. At the same time, the second turning bar 407 drives the first turning bar 405 to rotate 90 degrees around the second rotation axis 404. At this time, the first turning bar 405 and the second turning bar 407 are in a vertical state, which is convenient for subsequent hanging of cables. It is highly practical, and when the first turning bar 405 and the second turning bar 407 are in a retracted state, it does not affect the overall winding operation of the cable.

[0027] When the present invention is in use, the rubber sleeve 301 is aligned with the end of the cable, and the three conductors 205 are respectively passed through the three holes at the center of the rubber sleeve 301. At this time, the outer wall of the outer sheath 1 and the inner wall of the rubber sleeve 301 are in contact with each other, and the conductors 205 and the inner walls of the holes are in contact with each other, thereby ensuring the overall sealing of the cable and preventing oil or water from entering the internal space from the end of the cable. Then, the two fixing rings 303 are rotated around the first rotating shaft 302 until the ends of the two are in contact with each other, and then the two fixing rings 303 are fixed with the first bolt 304. At this time, the installation of the rubber sleeve 301 is completed, effectively ensuring the sealing, easy installation, and strong firmness. Finally, the three connectors 305 are respectively fixed to the ends of the conductors 205 by means of crimping and fitting with heat shrink sleeves, which is easy to operate. When it is necessary to suspend the cable or isolate the ground to hang it on a building or a bracket, it is only necessary to insert the hexagonal wrench into the driving hole on the knob 402 and then rotate the hexagonal wrench. Then the knob 402 rotates inside the first mounting belt 401 and slides outward with the limit block 403. At this time, the position of the first mounting belt 401 on the cable can be adjusted at will, and multiple identical first mounting belts 401 can be set at different positions on the cable, which is beneficial to the overall suspension of the cable and improves the stability of the cable. After adjusting the multiple first mounting belts 401 to the appropriate position, the hexagonal wrench is rotated in the opposite direction to rotate the knob 402. The limit block 403 is driven to press against the outer sheath 1, thereby limiting the position of the first mounting belt 401 and improving its firmness. Then, a finger is inserted into the groove reserved on the first rotating bar 405, and the second rotating bar 407 is pressed outward, thereby driving the second rotating bar 407 to rotate 90 degrees around the third rotating shaft 406. At the same time, the second rotating bar 407 drives the first rotating bar 405 to rotate 90 degrees around the second rotating shaft 404. At this time, the first rotating bar 405 and the second rotating bar 407 are in a vertical state, which is convenient for subsequent hanging of the cable and has strong practicality. When the first rotating bar 405 and the second rotating bar 407 are in the retracted state, it does not affect the overall winding operation of the cable. When the cable is broken and needs to be reconnected, it is only necessary to first cut off the irregular parts at both ends of the break, peel off the outer sheath 1 and the insulating layer 204 at both ends, and expose the conductor 205. Then, the integral part composed of the first insulating sleeve 501 and the second insulating sleeve 502 is placed between the two sections of the outer sheath 1, so that the end of the second insulating sleeve 502 is aligned with the three adjacent conductors 205, and the three conductors 205 are clamped inside the three second guide sleeves 505. At this time, the ends of the lining layer 202 and the filler 203 simultaneously contact the second insulating sleeve 502, and the three insulating layers 204 respectively contact the three second guide sleeves 505. Then, the three screws 506 on the second insulating sleeve 502 are tightened so that the ends of the screws 506 are pressed against the conductor 205, thereby achieving the fixation of the conductor 205 and the second guide sleeve 505. The second insulating sleeve 502, the second guide sleeve 505 and the conductor 205 at the corresponding position are fixed as a whole by screws 506, and then the same operation is repeated to fix the three conductors 205 of the other section on the first guide sleeve 504 in the first insulating sleeve 501 respectively, and fixed with another three screws 506. At this time, the connection between the two broken cable sections is completed, and the operation is efficient and flexible, which is convenient for later disassembly and modification. At the same time, since the first insulating sleeve 501 and the second insulating sleeve 502 and the first guide sleeve 504 and the second guide sleeve 505 are slidingly connected, and a spring 503 is installed between the first insulating sleeve 501 and the second insulating sleeve 502, it is convenient to adapt to the break spacing of different lengths by adjusting the overlap size of the first insulating sleeve 501 and the second insulating sleeve 502, which is highly practical. After the two sections of cable are re-connected, a pair of second mounting belts 601 and a protective sleeve 605 therebetween are respectively wrapped around one side of the second insulating sleeve 502, and a pair of third mounting belts 603 and a protective sleeve 605 therebetween are wrapped around the other side of the second insulating sleeve 502. The two protective sleeves 605 form a barrel structure, and the second mounting belt 601 and the adjacent third mounting belt 603 are locked by a second bolt 602. During the process of locking the second bolt 602, the rubber strip 607 is inserted into the socket 608, which solves the problem of the gap between the two protective sleeves 605, and the shielding pads 606 on the inner sides of the two protective sleeves 605 are pressed against the outer wall of the second insulating sleeve 502. At this time, the two protective sleeves 605 effectively protect the internal connection. At the same time, the rubber frame 604 on the inner side of the second mounting belt 601 and the third mounting belt 603 is in contact with the outer wall of the shielding layer 201, ensuring the overall sealing, preventing water or oil from entering the internal cavity through the gap, and having strong anti-oil pollution ability.
