Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of cable connectors, and specifically to a separable connector for 66 kV cables. Background Art
[0002] A 66 kV cable is composed of four basic unit core wires. When in use, it needs to maintain a sufficient safety distance from media such as the ground. After the cable is arranged according to requirements, cable double connectors in the interference position need to be assembled with connectors.
[0003] Current cable connectors mainly consist of plugs and sockets. However, connectors of this structure are not conducive to the release of torsion in longer cables. As the length of the cable increases, during the arrangement process, affected by manual traction interference and the rotation and release of the winding roller, the torsion on the cable will gradually increase. As a result, pressure will be exerted on the connectors on the cable double connectors. When the connectors are exposed to air and accelerated oxidation and corrosion occur, the connectors under the action of the cable's own torsion will be pressured and malfunction (including poor contact or disconnection of the light), and in severe cases, it will cause cable short - circuit or spontaneous combustion.

It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.
[0022] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention.
[0023] The following describes a 66 kV cable separable connector provided by some embodiments of the present invention with reference to the accompanying drawings.
[0024] Example 1: As shown in combination with Figures 1 to 10 A separable connector for a 66 kV cable provided by the present invention includes two sets of wire-end partitioning mechanisms 300 provided on the input cable 100 and the output cable 200 and at the two exposed ends of the input cable 100 and the output cable 200. Two sets of plug mechanisms 400 are provided on the two sets of wire-end partitioning mechanisms 300, and a socket mechanism 500 is provided between the two sets of plug mechanisms 400. One set of wire-end partitioning mechanism 300 is used to provide a partitioning carrier for the four basic units exposed at the end of the input cable 100, and the other set of wire-end partitioning mechanism 300 is used to provide a partitioning carrier for the four basic units exposed at the end of the output cable 200. The two sets of plug mechanisms 400 are used to provide a secondary transfer carrier for the two sets of wire-end partitioning mechanisms 300, and the socket mechanism 500 is used to provide a rotational anti-twist carrier for the two sets of plug mechanisms 400.
[0025] The plug mechanism 400 includes an insulating sub-terminal 410, and four jacks are provided inside the insulating sub-terminal 410. Four sets of quick-connect components 490 are evenly arranged in the four jacks. Two exhaust pipes 420 are provided in the insulating sub-terminal 410, and four sets of fixing bolts 430 are evenly arranged in the insulating sub-terminal 410 and the protective end 310; Positioning members 470 are movably installed at the top and bottom of the insulating sub-terminal 410, and two tension springs 480 are provided on the positioning members 470. A concave hole 440 is provided in the middle of the outer end of the insulating sub-terminal 410, and a sub-terminal cavity 450 is provided inside the insulating sub-terminal 410; The inner cavity of the exhaust pipe 420 is adaptively communicated with the sub-terminal cavity 450, and air windows are provided in the two slopes at the outer end of the exhaust pipe 420; The socket mechanism 500 includes a separating wiring assembly 510 provided between the two insulating sub-terminals 410. Four heat dissipation shells 520 are provided inside the separating wiring assembly 510, and fuse tubes 540 are provided inside the heat dissipation shells 520; The separating wiring assembly 510 includes an insulating main terminal 511, and four symmetrically distributed slots 517 are provided on both sides of the insulating main terminal 511; A beam rod 512 is provided in the middle of the insulating main terminal 511, and two nuts 513 are provided on the threaded sections at both ends of the beam rod 512; A main terminal cavity 518 is provided inside the insulating main terminal 511, and four evenly distributed assembly holes 516 are provided in the insulating main terminal 511; Chute grooves 514 are provided at both ends of the insulating main terminal 511, and a ventilation slot opening 515 is provided in the middle of the end face of the insulating main terminal 511; Exhaust slots 460 are provided in the middle of both ends of the insulating secondary terminal 410, and the exhaust slots 460 are symmetrically adapted to the ventilation slots 515; The beam rod 512 is made of stainless steel material, and the threaded sections at both ends of the beam rod 512 respectively penetrate into the two concave holes 440, and the nuts 513 arranged on the threaded sections are located in the concave holes 440.
[0026] During use, first strip the four basic unit core wires in the to-be-installed ends of the input cable 100 and the output cable 200, and then insert the exposed core wires into the protective end 310 along the sleeve 320 until the four core wires penetrate into the cavities of the four insulating card holders 330. The four groups of wire pressing clips 370 arranged inside the four insulating card holders 330 can effectively clamp and fix the four basic unit core wires; After the two wire head partitioning mechanisms 300 are respectively assembled with the input cable 100 and the output cable 200, the two assembled wire head partitioning mechanisms 300 can be docked with the two insulating secondary terminals 410, and the protective end 310 and the insulating secondary terminal 410 after docking are fixed by a plurality of fixing bolts 430. At this time, the contact head 340 can extrude the contact 492 outwards, and the contact 492 can extend into the inside of the arc guiding slot 530 and the sliding slot 514. Finally, the end of the contact 492 can be adaptively attached to the end of the fuse tube 540, and the four groups of basic unit core wires that are exposed and symmetrical of the input cable 100 and the output cable 200 can form independent circuits through the contact 492 and the fuse tube 540; During the wiring process, when the input cable 100 or the output cable 200 has torsion due to manual or external force, the positioning member 470 can be pulled outwards. At this time, the two plug mechanisms 400 can rotate along both ends of the socket mechanism 500, and finally the torsion in the input cable 100 and the output cable 200 can be effectively released.
[0027] Embodiment 2: Combined with Figures 4 to 10 As shown, on the basis of Embodiment 1, the wire head partitioning mechanism 300 includes a protective end 310 and a sleeve 320 arranged at the outer end of the protective end 310.
[0028] Preferably, the protective end 310 and the sleeve 320 can increase the frictional resistance of the outer insulating layer of the input cable 100 or the output cable 200. At this time, the exposed core wires of the input cable 100 and the output cable 200 can be effectively partitioned in the insulating space, thereby avoiding the occurrence of a series arc phenomenon due to the too-close distance between the four basic unit core wires.
[0029] Four transverse holes are provided inside the protective end 310, and four insulating card holders 330 are arranged in the four transverse holes. Two wire pressing clips 370 are arranged inside the insulating card holders 330; There are connectors 340 provided on two wire pressing clamps 370. There is a limiting rod 350 provided inside the connector 340, and there are two springs 360 provided on the limiting rod 350; The connector 340 is integrally in a T-shaped structure, and there are two sliding grooves opened at one end of the connector 340 close to the insulating card seat 330; The slider at the outer end of the wire pressing clamp 370 is movably installed on the limiting rod 350; One end of the spring 360 is adaptively pressed against the slider, and the other end of the spring 360 is adaptively pressed against the inner wall of the sliding groove of the connector 340; The connector 340 is integrally in a conical structure, and a semi-cylindrical groove is opened on the inner side of the wire pressing clamp 370, and anti-slip notches are opened on the inner wall of the semi-cylindrical groove.
[0030] Preferably, after the anti-slip notches on the inner walls of the two wire pressing clamps 370 press the core wire tightly, under the continuous shrinking and pressing of the insulating card seat 330 on the two wire pressing clamps 370, finally the core wire can form a stable path with the two wire pressing clamps 370 and the connector 340. The connector 340 can be normally docked with the fuse tube 540 through the contact 492. At this time, the lengthened and multi-stage assembled components can be effectively cooled during continuous power transmission.
[0031] Embodiment 3: Combined with Figure 1 and Figure 8 As shown, on the basis of Embodiment 1, the quick connection assembly 490 includes an insulating sleeve 491. A sliding hole is opened inside the insulating sleeve 491, and a contact 492 is movably installed in the sliding hole; A compression spring 493 is provided outside the contact 492.
[0032] Preferably, the insulating sleeve 491 is composed of a T-shaped stud and a gasket. The gasket is movably installed inside the insulating sleeve 491. One end of the compression spring 493 is adaptively pressed against the gasket, and the other end of the compression spring 493 is adaptively pressed against the inner wall of the insulating sleeve 491; When the two symmetrically distributed contacts 492 are pressed and extended outwards, the fuse tube 540 can be effectively fixed, and the various components forming the path can cooperate with the input cable 100 and the output cable 200 to stretch, so as to avoid the fuse tube 540 from loosening or falling off due to jitter during layout.
[0033] Embodiment 4: Combined with Figure 9 and Figure 10 As shown, in the above embodiment, the heat dissipation housing 520 is made of thickened insulating plastic, and pre-installation slots are opened on the outer side of the heat dissipation housing 520; Leading arc grooves 530 are opened at both ends of the heat dissipation housing 520.
[0034] Preferably, the heat dissipation housing 520 is used to reduce the interference caused by vibration fluctuations to the fuse tube 540, and at the same time can provide heat dissipation protection for the continuously operating and heat-releasing fuse tube 540, and the inner end of the voltage boosting and stabilizing block 550 cooperates with the heat dissipation housing 520 to provide stability enhancement protection for the assembled fuse tube 540.
[0035] The socket mechanism 500 further includes four voltage boosting and stabilizing blocks 550 and four fasteners 560; One end of the fastener 560 is provided with a column, and the column is adaptively clamped in the hole outside the voltage boosting and stabilizing block 550, and a bolt is arranged in the notch at the other end of the fastener 560.
[0036] Preferably, when one or more fuse tubes 540 fail due to short circuit and are protected by open circuit, the fuse tubes 540 in the four basic unit intervals after zoning can be safely replaced by sequentially loading and unloading multiple groups of fasteners 560, thereby avoiding accidental discharge phenomena during the replacement of the fuse tubes 540.
[0037] The working principle and usage process of the present invention: The 66KV cable is composed of four basic units, and the four basic units are different. The rated voltage of the four cores of the 66kv cable is 10kV / 10kV, and the safe distance between the 66KV cable after erection and residential areas and industrial and mining enterprise areas is 6.5 meters; In non-residential areas, but the safe distance for pedestrians and vehicles passing by is 5.5 meters, the safe distance in areas with difficult traffic is 4.5 meters, the safe distance on the road surface is 7 meters, the safe distance from the top of the railway track is 7.5 meters, etc.; There are certain drawbacks when installing and transferring such cables. When the cable is continuously stretched along the installation point, the cable will increase its own torsion force after being forced to stretch, which will lead to an increase in the overall torsion force of the cable and cause the phenomenon of exposed ribs. Therefore, it will cause the cable to droop and twist locally after being erected in the air. In severe cases, it will cause an increase in the torsion force of the cable connector and result in breakage; And this connector sets the traditional single plug and single socket structure into a single socket and four plug structure with anti-disconnection and contact protection; When the four basic unit core wires in the input cable 100 and the output cable 200 are exposed, the exposed core wires of the input cable 100 and the output cable 200 can be inserted into the two sets of wire-end partition mechanisms 300. Then, the combined connector 340 and the pressure clamp 370 are pulled out from the insulating socket 330 until the exposed core wires extend out along the insulating socket 330. Then, the core wires can be folded and thickened. Next, the end of the folded and thickened core wire is inserted into the inner sides of the two pressure clamps 370. As the two pressure clamps 370 are reset towards the inside of the insulating socket 330, finally, restricted by the conical holes inside the insulating socket 330, the two pressure clamps 370 can effectively fix and lock the core wires. At this time, the four connectors 340 arranged at the inner end of the protective end 310 can form a matrix structure. Then, the inner end of the protective end 310 is moved closer to the outer end of the insulating sub-terminal 410 until the ends of the four connectors 340 are inserted into the four insulating sleeves 491. Next, the protective end 310 and the insulating sub-terminal 410 are fixed by four sets of fixing bolts 430; At this time, the end of the connector 340 can extrude the contact 492 outwards, and the extruded end of the contact 492 will be pressed and extend into the circular groove formed by the chute 514 and the guiding arc groove 530; After the input cable 100 and the output cable 200 are assembled by the connector, as the input cable 100 and the output cable 200 are stretched and arranged outwards, when the cable generates torsion due to release, the four positioning members 470 arranged in the two insulating sub-terminals 410 can be pulled outwards. At this time, the four positioning members 470 can be withdrawn from the insulating main terminal 511 outwards. At this time, the socket mechanism 500 as a whole can freely rotate along the middle of the two plug mechanisms 400, and the torsion generated by the input cable 100 or the output cable 200 during the arrangement process can be effectively released from the socket mechanism 500; Since the four basic unit core wires are of different thicknesses, after the four basic units generate high temperature during long-term use and one or more of the four basic units short-circuit due to high temperature or accident, the four basic units symmetrically distributed in the input cable 100 and the output cable 200 can be protected by the fuse 540. When the symmetric basic unit fails due to short circuit in an instant, the fuse 540 can quickly form a power-off protection; The main terminal cavity 518 and the sub-terminal cavity 450 form a communication cavity through the air exchange slot 515 and the exhaust slot 460. At this time, the four basic units after matrix partitioning can be evenly distributed inside the cavity. As the four basic units heat up during use, the heated air flow can flow along the cavity and be discharged by the four exhaust pipes 420. Finally, the heat energy generated by the four basic units can be effectively released.
[0038] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
