Description

Technical Field

[0001] The present invention relates to the technical field of cable connectors, in particular to a 66kV cable detachable connector. Background Art

[0002] The 66KV cable is composed of four basic unit core wires and needs to maintain a sufficient safety distance from the ground and other media when in use. When this type of cable is arranged according to needs, the cable double joints in the interfering position need to be assembled with connectors.

[0003] Current cable connectors are mainly composed of plugs and sockets, and this type of connector structure is not conducive to the release of torque in longer cables. As the cable length increases, during the layout, the torque on the cable will gradually increase due to the interference of manual traction and the rotation release of the reel, which will put pressure on the connector on the cable double joint. When the connector is exposed to air and accelerated oxidation corrosion occurs, the connector will be stressed by the cable's own torque and malfunction (including poor contact or broken light). In severe cases, it will cause the cable to short circuit or spontaneous combustion.

[0004] In view of this, a 66kV cable detachable connector is designed to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0051] To make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other without conflict.

[0052] It is to be understood that these descriptions are illustrative only and are not intended to limit the scope of the invention.

[0053] A 66 kV cable detachable connector provided by some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0054] Example 1:

[0055] Combine Figures 1 to 10 As shown, the present invention provides a 66kV cable detachable connector, including two sets of wire end partitioning mechanisms 300 arranged on the input cable 100 and the output cable 200 and on the two exposed ends of the input cable 100 and the output cable 200, two sets of plug mechanisms 400 and a socket mechanism 500 arranged between the two sets of plug mechanisms 400. One set of wire end partitioning mechanisms 300 is used to provide a partition carrier for the four basic units exposed at the end of the input cable 100, and the other set of wire end partitioning mechanisms 300 is used to provide a partition 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 back-twist carrier for the two sets of plug mechanisms 400.

[0056] The plug mechanism 400 includes an insulating secondary terminal 410 having four internal insertion holes, each of which contains four evenly spaced sets of quick-connect assemblies 490. Two exhaust pipes 420 are disposed within the insulating secondary terminal 410. Four evenly spaced sets of fixing bolts 430 are disposed within the insulating secondary terminal 410 and the protective terminal 310.

[0057] Positioning members 470 are movably mounted at the top and bottom of the insulating secondary terminal 410, and two tension springs 480 are provided on the positioning members 470. A recessed hole 440 is provided in the middle of the outer end of the insulating secondary terminal 410, and a secondary terminal cavity 450 is provided inside the insulating secondary terminal 410.

[0058] The inner cavity of the exhaust pipe 420 is adapted to be connected to the secondary terminal cavity 450, and air windows are opened in two slopes at the outer end of the exhaust pipe 420;

[0059] The socket mechanism 500 includes a separate wiring assembly 510 disposed between two insulating secondary terminals 410 , and four heat dissipation housings 520 and a fuse 540 disposed inside the heat dissipation housings 520 are disposed inside the separate wiring assembly 510 ;

[0060] The separation wiring assembly 510 includes an insulating main terminal 511 , and four slots 517 are symmetrically distributed on both sides of the insulating main terminal 511 ;

[0061] A beam 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 512;

[0062] A main terminal cavity 518 is provided inside the insulating main terminal 511, and four evenly distributed assembly holes 516 are provided inside the insulating main terminal 511;

[0063] Both ends of the insulating main terminal 511 are provided with a sliding groove 514, and the middle of the end surface of the insulating main terminal 511 is provided with a ventilation notch 515;

[0064] An exhaust notch 460 is provided in the middle of both ends of the insulating secondary terminal 410, and the exhaust notch 460 is symmetrically matched with the ventilation notch 515;

[0065] The beam rod 512 is made of stainless steel, and the threaded sections at both ends of the beam rod 512 respectively penetrate into the two recessed holes 440 , and the nuts 513 provided on the threaded sections are located in the recessed holes 440 .

[0066] When in use, the four basic unit core wires in the terminals to be installed of the input cable 100 and the output cable 200 are stripped in advance, and then the exposed core wires are extended into the protective terminal 310 along the sleeve 320 until the four core wires pass through the inner cavities of the four insulating clamps 330. The four sets of wire clamps 370 arranged inside the four insulating clamps 330 can effectively clamp and fix the four basic unit core wires;

[0067] After the two sets of wire end partitioning mechanisms 300 are respectively assembled with the input cable 100 and the output cable 200, the two assembled wire end partitioning mechanisms 300 can be docked with the two sets of insulating sub-terminals 410, and the docked protective terminals 310 and insulating sub-terminals 410 can be fixed using multiple sets of fixing bolts 430. At this time, the connector 340 can extrude the contacts 492 outward, and the contacts 492 can extend into the interior of the arc guide groove 530 and the slide groove 514. Finally, the ends of the contacts 492 can be adapted to fit on the ends of the fuse tube 540. The four exposed and symmetrical basic unit core wires of the input cable 100 and the output cable 200 can form independent pathways through the contacts 492 and the fuse tube 540.

[0068] During the wiring process, when torque exists in the input cable 100 or the output cable 200 due to manual or external force, the positioning member 470 can be pulled outward. At this time, the two sets of plug mechanisms 400 can be rotated along the two ends of the socket mechanism 500, and the torque in the input cable 100 and the output cable 200 can be effectively released.

[0069] Example 2:

[0070] Combine Figures 4 to 10 As shown, based on Example 1, the wire end partitioning mechanism 300 includes a protective end 310 and a sleeve 320 arranged at the outer end of the protective end 310.

[0071] Preferably, the protective end 310 and the sleeve 320 can increase the friction resistance of the outer insulation 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 within the insulation space, thereby avoiding the occurrence of chain arc phenomenon due to the four basic unit core wires being too close to each other.

[0072] The protective end 310 has four horizontal holes formed inside, and four insulating holders 330 are provided in the four horizontal holes. Two wire clamps 370 are provided inside the insulating holders 330.

[0073] The two wire clamps 370 are provided with a joint 340 , a limit rod 350 is provided inside the joint 340 , and two springs 360 are provided on the limit rod 350 ;

[0074] The connector 340 is in a T-shaped structure as a whole, and two slideways are provided at one end of the connector 340 close to the insulating holder 330;

[0075] The slider at the outer end of the wire clamp 370 is movably mounted on the limiting rod 350;

[0076] One end of the spring 360 is adapted to bear pressure on the slider, and the other end of the spring 360 is adapted to bear pressure on the inner wall of the slideway of the connector 340;

[0077] The connector 340 is of a tapered structure as a whole, and a semi-cylindrical groove is provided on the inner side of the wire pressing clamp 370 , while an anti-slip groove is provided on the inner wall of the semi-cylindrical groove.

[0078] Preferably, after the core wire is compressed by the anti-slip grooves on the inner walls of the two wire clamps 370, the insulating holder 330 continuously contracts and compresses the two wire clamps 370, and finally a stable passage is formed between the core wire and the two wire clamps 370 and the connector 340. The connector 340 can be normally docked with the fuse 540 through the contact 492. At this time, the lengthened and multi-stage assembled components can effectively dissipate heat during continuous power transmission.

[0079] Example 3:

[0080] Combine Figure 1 and Figure 8 As shown, based on embodiment 1, the quick-connect assembly 490 includes an insulating sleeve 491 , a sliding hole is provided inside the insulating sleeve 491 , and a contact 492 is movably installed in the sliding hole;

[0081] A compression spring 493 is provided on the outside of the contact 492 .

[0082] Preferably, the insulating sleeve 491 is composed of a T-shaped column head and a gasket, and the gasket is movably installed inside the insulating sleeve 491, and one end of the compression spring 493 is adapted to bear pressure on the gasket, while the other end of the compression spring 493 is adapted to bear pressure on the inner wall of the insulating sleeve 491;

[0083] When the two symmetrically distributed contacts 492 are pressed and stretched outward, the fuse 540 can be effectively fixed, and the various components forming the passage can cooperate with the input cable 100 and the output cable 200 to stretch, thereby preventing the fuse 540 from loosening or falling off due to shaking during installation.

[0084] Example 4:

[0085] Combine Figure 9 and Figure 10 As shown, in the above embodiment, the heat dissipation housing 520 is made of thickened insulating plastic, and the outer side of the heat dissipation housing 520 is provided with pre-installed slots;

[0086] Arc guiding grooves 530 are formed at both ends of the heat dissipation housing 520 .

[0087] Preferably, the heat dissipation housing 520 is used to reduce the interference of vibration fluctuations on the fuse 540, and at the same time can provide heat dissipation protection for the fuse 540 that is continuously running and releasing heat, and the inner end of the stabilizing pressure block 550 cooperates with the heat dissipation housing 520 to provide stabilization protection for the assembled fuse 540.

[0088] The socket mechanism 500 further includes four stabilizing pressure blocks 550 and four fasteners 560;

[0089] One end of the fastener 560 is provided with a column, and the column is adapted to be clamped into a hole on the outside of the stabilizing pressure block 550 , and a bolt is provided in a slot at the other end of the fastener 560 .

[0090] Preferably, when one or more fuses 540 fail due to a short circuit and are protected by a circuit breaker, the fuses 540 in the four basic unit intervals after partitioning can be safely replaced by sequentially loading and unloading multiple sets of fasteners 560, thereby avoiding accidental discharge during the replacement of the fuses 540.

[0091] The working principle and use process of the present invention are as follows: 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 and residential areas and industrial and mining enterprises after installation is 6.5 meters;

[0092] In non-residential areas, but with pedestrians and vehicles passing by, the safe distance is 5.5 meters; in areas with difficult traffic, the safe distance is 4.5 meters; on highways, the safe distance is 7 meters; on the top of railway tracks, the safe distance is 7.5 meters, etc.

[0093] This type of cable has certain drawbacks when it is installed and connected. When the cable is continuously stretched along the installation point, the cable will increase its own torque after being forced to stretch, which will lead to an increase in the overall torque of the cable and the occurrence of cable tension. As a result, the cable will partially fall and twist after being installed in the air. In severe cases, the cable connector will be damaged due to the increased torque.

[0094] This connector changes the traditional single-plug and single-socket structure to a four-plug structure with a single socket and anti-contact break protection;

[0095] 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 partitioning mechanisms 300, and then the combined connector 340 and the wire clamp 370 are pulled out from the insulating card seat 330 until the exposed core wires are extended along the insulating card seat 330. The core wires can be folded and thickened, and then the folded and thickened core wire ends are inserted into the inner sides of the two wire clamps 370. As the two wire clamps 370 move toward the insulating card seat, the core wires can be folded and thickened. The internal resetting of the base 330 is ultimately constrained by the tapered hole inside the insulating base 330, and the two wire clamps 370 can effectively secure and lock the core wire. At this time, the four connectors 340 provided at the inner end of the protective terminal 310 can form a matrix structure. Then, the inner end of the protective terminal 310 is moved closer to the outer end of the insulating auxiliary terminal 410 until the ends of the four connectors 340 are inserted into the interior of the four insulating sleeves 491. Then, the protective terminal 310 and the insulating auxiliary terminal 410 are fixed using four sets of fixing bolts 430.

[0096] At this time, the end of the connector 340 can push the contact 492 outward, and the extruded end of the contact 492 will be pressed and extend into the annular groove formed by the slide groove 514 and the arc guide groove 530;

[0097] After the input cable 100 and the output cable 200 are assembled with the connector, as the input cable 100 and the output cable 200 are stretched and arranged outward, when the cables generate torque due to release, the four positioning members 470 provided in the two insulating secondary terminals 410 can be pulled outward. At this time, the four positioning members 470 can be withdrawn outward from the insulating main terminals 511. At this time, the entire socket mechanism 500 can freely rotate along the middle of the two sets of plug mechanisms 400, and the torque generated by the input cable 100 or the output cable 200 during the arrangement process can be effectively released from the socket mechanism 500.

[0098] Since the core wires of the four basic units are of different thicknesses, if the four basic units generate high temperatures after long-term use and one or more of the four basic units short-circuit due to high temperature or an 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 symmetrical basic units fail due to a short circuit, the fuse 540 can quickly provide power-off protection.

[0099] The main terminal cavity 518 and the auxiliary terminal cavity 450 form a connecting cavity through the ventilation slot 515 and the exhaust slot 460. At this time, the four basic units that have been divided into matrix partitions can be evenly distributed inside the cavity. As the four basic units heat up during use, the heated air flow can follow the cavity and be discharged through the four exhaust pipes 420, ultimately allowing the heat energy generated by the four basic units to be effectively released.

[0100] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
