Description

Technical Field

[0001] This invention relates to the field of live-line working equipment technology, and in particular to a connector device and a bypass system using the connector device. Background Technology

[0002] The bypass live-line working method is a live-line working method that uses bypass cable systems, bypass switches and other bypass diversion equipment to connect to the ring main unit in the power system. It can complete emergency repairs, temporary power supply and other work projects without power interruption or with short power outages.

[0003] Because the interface of the equipment sleeve on the ring main unit is inconsistent with the interface of the bypass cable direct connector, an intermediate unit is required for conversion. Currently, the connection scheme between the bypass system and the ring main unit used in the market is completed through a bypass cable with a T-type detachable connector and a bypass direct connector installed at both ends, and an intermediate connector. One end of the T-type detachable connector connects to the ring main unit's equipment sleeve, and one end of the bypass direct connector connects to the intermediate connector. The other end of the intermediate connector serves as the interface between the ring main unit and the bypass cable system, connecting to the bypass direct connector, thus completing the connection between the ring main unit and the bypass system.

[0004] Because the cable and intermediate connector equipped with T-type detachable connectors and bypass direct-plug connectors are two independent structures, they need to be installed in stages, which increases the difficulty of construction. On the other hand, the cable equipped with T-type detachable connectors and bypass direct-plug connectors has two joints and cables, involving too many units, resulting in high manufacturing costs. Furthermore, the large number of units involved reduces the system's fault tolerance, increases the probability of failure, and also prolongs the on-site installation time. Summary of the Invention

The insulating inner shell 2 is located within the through groove 111 of the outer shell 1, forming a first slot 21 between the outer shell 1 and the insulating inner shell 2. The first slot 21 and the second slot 251 are spaced apart and located at both ends of the outer shell 1. The conductor 3 passes through the through hole 252. By using the insulating inner shell 2 as an insulating material, electrical conduction between the charged conductor 3 and the outer shell 1 is prevented, thereby improving the safety of the connector device and simplifying its structure. Furthermore, by connecting one end of the conductor 3 to the equipment sleeve interface 71 on the ring main unit 7 and the other end of the conductor 3 to the direct-plug connector of the bypass cable 8, the connection between the ring main unit 7 and the bypass cable 8 is achieved, further simplifying the structure of the connector device. This invention simplifies the structure of the connector device, reduces costs, and improves operational stability.

[0055] In a specific embodiment of the present invention, the conductor 3 can be positioned on a mold, and an insulating inner shell 2 can be formed on the periphery of the conductor 3 by a secondary thermoplastic molding process; wherein, the insulating inner shell 2 forms a second slot 251 and a through hole 252 corresponding to the conductor 3, thereby improving the connection strength between the conductor 3 and the insulating inner shell 2.

[0058] In another embodiment of the present invention, the insulating inner shell 2 and the outer shell 1 may be an interference fit; or, the insulating inner shell 2 and the outer shell 1 may be screw-locked. When the insulating inner shell 2 and the outer shell 1 are screw-locked, a clearance hole 115 is provided in the outer shell 1, the clearance hole 115 communicating with a through groove 111 inside the outer shell 1, and the screw passes through the clearance hole 115 to lock with the insulating inner shell 2.

[0059] In another embodiment of the present invention, provided that the insulating inner shell 2 can be used to avoid blocking the electrical conduction between the outer shell 1 and the conductor 3, the insulating inner shell 2 can be any form of insulating material.

[0060] In one embodiment of the present invention, combined with Figure 3 , Figure 4 , Figure 5 as well as Figure 7 As shown, the inner wall of the through groove 111 is provided with a boss 112; the insulating inner shell 2 includes an insert 22 and a connector body 23. The insert 22 is sleeved on the outer surface of the connector body 23, and the insert 22 is limited and connected to the boss 112 so that the insert 22 and the connector body 23 are positioned in the through groove 111. The connector body 23 and the outer shell 1 enclose each other to form a first slot 21; the connector body 23 is provided with a second slot 251 and a through hole 252. Among them, part of the material of the connector body 23 is an insulating material to prevent electrical conduction between the conductive body 3 and the outer shell 1.

[0061] In this embodiment, a boss 112 is provided on the inner wall to form an assist structure. When the insulating inner shell 2 enters the through groove 111 from one end, the periphery of the insulating inner shell 2 can abut against the boss 112 through the insert 22 to prevent the insulating inner shell 2 from sliding out from the other end of the outer shell 1, thereby improving the stability of the installation.

[0062] In another embodiment of the invention, such as Figure 7 As shown, the outer casing 1 is provided with a clearance hole 115, which is located adjacent to the boss 112. When the insert 22 abuts against the boss 112, the screw passes through the clearance hole 115 and locks with the insert 22.

[0063] In another embodiment of the invention, adhesive may be used to fill the space between the insert 22 and the boss 112.

[0064] In another embodiment of the invention, the insert 22 abuts against the boss 112, and the insert 22 is interference-fitted with the inner surface of the through groove 111.

[0065] In one embodiment of the present invention, combined with Figure 3 and Figure 7 As shown, the connector body 23 includes an outer shield 24, an insulator 25, and an inner shield 26. The insulator 25 is provided with a second slot 251 and a through hole 252. The end of the insulator 25 away from the second slot 251 is surrounded by the outer shell 1 to form a first slot 21.

[0071] In another embodiment of the present invention, the outer shield 24 and the inner shield 26 are made of semi-conductive materials.

[0072] In another embodiment of the present invention, the outer shield 24, the insulator 25, and the inner shield 26 can be an integral structure. That is, the outer shield 24 and the inner shield 26 can be fabricated first, then placed in an injection molding machine to injection mold the insulator 25, thus forming the insulator 25, the outer shield 24, and the inner shield 26 integrally. Alternatively, the outer shield 24 and the inner shield 26 can be fabricated after the insulator 25 is fabricated. Alternatively, the outer shield 24, the insulator 25, and the inner shield 26 can be fabricated separately, and then connected into a single unit through welding or a secondary thermoplastic process.

[0073] In another embodiment of the present invention, the coverage area of ​​the inner shield 26 to the inner wall of the through groove 111 partially overlaps with the coverage area of ​​the outer shield 24 to the inner wall of the through groove 111 to improve the shielding effect.

[0077] In another embodiment of the invention, the insulator 25 may be an inorganic material, such as ceramic.

[0078] In another embodiment of the present invention, the insulator 25 may be an organic material, such as a plastic material (polycarbonate material, ABS material, etc.).

[0079] In one embodiment of the present invention, combined with Figure 3As shown, one of the outer shield 24 and the insert 22 is provided with a first protrusion 221, and the other is provided with a first groove 241.

[0080] In this embodiment, the outer shield 24 and the insert 22 are connected by a first protrusion 221 and a first groove 241 to improve the connection strength between the outer shield 24 and the insert 22 and prevent the outer shield 24 from coming loose from the insert 22.

[0081] In one embodiment of the present invention, combined with Figure 3 As shown, the outer shield 24 has a plurality of limiting protrusions 242 on the surface facing away from the insulator 25, and the end of the limiting protrusion 242 away from the outer shield 24 abuts against the inner wall surface of the through groove 111.

[0082] In this embodiment, the surface of the outer shield 24 is provided with a plurality of limiting protrusions 242. When the outer shield 24 is disposed in the through groove 111, the limiting protrusions 242 of the outer shield 24 can abut against the inner wall surface of the through groove 111 to improve installation stability.

[0083] In one embodiment of the present invention, combined with Figure 3 As shown, one of the conductor 3 and the inner shield 26 is provided with a second protrusion 33, and the other is provided with a second groove 261. The second protrusion 33 is accommodated and confined within the second groove 261, so that the conductor 3 and the inner shield 26 can be inserted and fitted together. The conductor 3 is partially protruding from the inner shield 26. That is to say, the inner wall surface of the clearance hole 262 is provided with a second protrusion 33 or a second groove 261 to position the conductor 3.

[0084] In this embodiment, the conductor 3 and the inner shield 26 are connected by a second protrusion 33 and a second groove 261 to improve the connection strength between the conductor 3 and the inner shield 26 and prevent the conductor 3 from coming loose from the inner shield 26.

[0086] In this embodiment, the external thread 32 can be threadedly connected to the equipment sleeve interface 71 on the ring main unit 7. The pin hole 31 can mate with the plug pin of the through connector of the bypass cable 8.

[0087] In one embodiment of the present invention, combined with Figure 5 and Figure 7As shown, the outer casing 1 includes: a first casing 11, a second casing 13, and a plurality of steel balls 12; wherein, the first casing 11 is provided with a through groove 111 and a plurality of limiting holes 113, the plurality of limiting holes 113 being provided on the same circumference of the first casing 11, and the plurality of limiting holes 113 communicating with a first slot 21; a steel ball 12 is limited in a limiting hole 113; the second casing 13 is slidably fitted onto the first casing 11 and covers the plurality of limiting holes 113, and a supporting block 131 is provided on the surface of the second casing 13 facing the first casing 11. The supporting block 131 may be provided on the inner wall surface of the second casing 13.

[0088] In another embodiment of the present invention, the first housing 11 and / or the second housing 13 are made of metal.

[0089] In this embodiment, the outer casing 1 has a locked state and an unlocked state.

[0090] In the holding state, the second housing 13 slides relative to the first housing 11, and the abutment block 131 corresponds to the plurality of limiting holes 113 so that the plurality of steel balls 12 partially protrude from the groove wall of the through groove 111, so that the protruding parts of the plurality of steel balls 12 engage with the straight connector of the bypass cable 8.

[0091] In the unlocked state, the second housing 13 slides relative to the first housing 11, and the abutment block 131 is offset from the multiple limiting holes 113, thus removing the abutment force of the abutment block 131 on the steel ball 12, so that the multiple steel balls 12 are partially in a free-moving state. When the direct connector of the bypass cable 8 moves, it can apply a force to the steel ball 12, and the steel ball 12 retracts into the limiting hole 113 to realize the removal of the direct connector.

[0092] In one embodiment of the present invention, combined with Figure 5 and Figure 7 As shown, the outer wall of the first housing 11 is provided with a limiting part 114, which is disposed opposite to one end of the second housing 13. The housing 1 also includes a spring 14, which is sleeved on the first housing 11.
