Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage connectors, in particular to a single-core high-voltage connector. Background Art

[0002] High voltage cable connector is a device suitable for connecting 1140V~10kV power cable circuits in coal mining tunnels in coal mines. It can be used for wiring various UGSP monitoring shielded rubber sheathed cables when they are powered by mobile substations. It can be connected at both ends of the cable for mutual plugging, and its half explosion-proof connection part can also be connected to the mobile substation.

[0003] For example, publication number CN220253533U discloses a single-core high-voltage connector, including a butt tube, a plug and a rubber support tube, wherein two plugs are provided, and the plugs are symmetrically installed at both ends of the butt tube by bolts, and two rubber support tubes are also provided, and the rubber support tube is installed at one end of the plug by threaded engagement, an insulating filling A is provided inside the butt tube, and a connecting tube is provided through the center of the insulating filling A, an insulating filling B is provided inside the plug, and a plug is provided through the center of the insulating filling B, and a U-shaped groove and a conical hole are provided at the end of the plug of this scheme, and a conical extrusion head is installed inside the connecting tube matched therewith, and after the end of the plug is inserted into the connecting tube, it is extruded with the conical extrusion head, so that the end of the plug is bent and deformed outward, so that the outer surface of the plug is close to the inner wall of the connecting tube, thereby increasing the contact area between the two, and the extrusion connection method is also relatively stable, avoiding poor contact.

[0004] However, the prior art cannot fix the connected cable. In the prior art, the cable is fixed to the welding head in the installation shell through the connecting head, and the installation shell is held and moved. The connecting ring fixed on one side of the welding head drives the rubber ring to be sleeved on the conical head as the installation shell moves, so that the cable is connected and used. However, the rubber ring is sleeved on the conical head without a fixing structure. When the staff moves and installs the other end of the cable, the cable will generate a certain pulling force when it moves, which can easily make the rubber ring sleeved on the conical head loose and fall off from the conical head, thereby reducing the stability of the connection.

[0035] See also Figure 1-5 The utility model provides a technical solution: a single-core high-voltage connector, comprising:

[0036] The connector body includes a connection shell 11, both ends of the connection shell 11 are fixedly connected to a first fixing ring 12, both sides of the connection shell 11 are provided with a mounting structure, a connector 14 is provided on a side of the mounting structure away from the connection shell 11, an insulating layer 15 is fixedly connected inside the connection shell 11, a first connection structure is provided inside the insulating layer 15, and second connection structures are provided on both sides of the first connection structure;

[0038] The dustproof body includes a dustproof structure, and the dustproof structure is arranged at one end of the connecting head 14 away from the connecting shell 11.

[0039] like Figure 2 and Figure 3As shown, the mounting structure includes a mounting shell 131, and the mounting shell 131 is clamped with the connecting head 14, the mounting shell 131 is slidably connected to both sides of the connecting shell 11, and the end of the mounting shell 131 close to the connecting shell 11 is fixedly connected with a second fixing ring 132, and the second fixing ring 132 is clamped with the first fixing ring 12, the first connecting structure includes a connecting pipe 161, and the connecting pipe 161 is fixedly connected with the mounting ring 21, the connecting pipe 161 is fixedly connected to the inside of the insulating layer 15, and the two ends of the connecting pipe 161 are threadedly connected with the conical head 162, and the second connecting The structure includes a welding head 171, which is fixedly connected to the inside of the mounting shell 131. The end of the welding head 171 close to the connecting pipe 161 is fixedly connected to a connecting ring 172, and the end of the connecting ring 172 away from the welding head 171 is fixedly connected to a rubber ring 174. When in use, one end of the cable is welded to the welding head 171, and the mounting shell 131 is held and moved. The connecting ring 172 fixed on one side of the welding head 171 drives the rubber ring 174 to be sleeved on the conical head 162 as the mounting shell 131 moves, so that the cable is connected and used.

[0040] like Figure 3 and Figure 5As shown, the second connection structure also includes a card slot 173, and the card slot 173 is arranged in an annular array at one end of the connecting ring 172 close to the welding head 171. The fixed structure includes a card block 221, and the card block 221 is slidably connected to one end of the mounting ring 21 in an annular array. The end of the card block 221 close to the connecting pipe 161 is fixedly connected to a connecting block 222, and both sides of the connecting block 222 are fixedly connected to sliders 223, and the outer wall of the slider 223 is slidably connected to a slide groove 224, and the slide grooves 224 are both arranged in the connecting pipe 161 and the mounting ring 21. The fixed structure also includes a placement groove 225, and the placement grooves 225 are arranged in an annular array on both sides of the connecting pipe 161.

When in use, the mounting shell 131 is held and moved, and the welding head 171 installed in the mounting shell 131 drives the connecting ring 172 and the mounting ring 161 as the mounting shell 131 moves. The card slot 173 moves in the connecting tube 161. Since the connecting ring 172 and the card slot 173 are in close contact with the mounting ring 21, the card block 221 connected to the mounting ring 21 is squeezed as the card slot 173 and the connecting ring 172 move. The connecting block 222 fixed at one end of the card block 221 drives the slider 223 to slide in the slide groove 224 on the mounting ring 21 and the connecting tube 161 as the card block 221 is squeezed. The first compression spring fixed at one end of the connecting block 222 is pressed. The spring 226 is compressed as the slide groove 224 slides, thereby driving the block 221 to move in the groove on the mounting ring 21. When the slot 173 moves to the block 221, since the slot 173 is a hole, the block 221 cannot be squeezed. The first compression spring 226 rebounds after losing the squeezing of the block 221, so that the block 221 is clamped in the slot 173, thereby fixing the slot 173 that has been sleeved and stably connecting the cable.

[0041] like Figure 3 As shown, the dustproof structure includes a closing leaf 311, and the closing leaf 311 is arranged in an annular array at one end of the connector 14 away from the mounting shell 131. The closing leaf 311 is fixedly connected to the second compression spring 312 at one end of the connector 14, and the second compression spring 312 is fixedly connected to the connector 14. When in use, the cable is moved to the welding head 171 through one end of the connector 14, and the closing leaf 311 installed at one end of the connector 14 is squeezed as the cable moves, and the second compression spring 312 fixed at one end of the closing leaf 311 is compressed as the closing leaf 311 is squeezed, so that the cable can be connected smoothly. When the cable connection is completed, the squeezing of the closing leaf 311 is lost, and the second compression spring 312 rebounds after losing the squeezing of the closing leaf 311, so that the closing leaf 311 is tightly fitted to the cable, thereby preventing dust in the environment from entering the welding head 171 through the connection between the connector 14 and the cable, causing damage to the cable and short circuit.

[0042] Working principle: First, when the cable needs to be connected, the cable is moved to the welding head 171 through one end of the connector 14. The closing leaf 311 installed at one end of the connector 14 is squeezed as the cable moves, and the second compression spring 312 fixed at one end of the closing leaf 311 is compressed as the closing leaf 311 is squeezed, so that the cable can be connected smoothly. Then, the welding head 171 installed inside the mounting shell 131 drives the connecting ring 172 and the card slot 173 to move in the connecting pipe 161 as the mounting shell 131 moves. Since the connecting ring 172 and the card slot 173 are in contact with the mounting ring 21, the card block 221 connected to the mounting ring 21 is squeezed as the card slot 173 and the connecting ring 172 move. The connecting block 222 fixed at one end of the card block 221 drives the slider 223 between the mounting ring 21 and the connecting pipe 161 as the card block 221 is squeezed. 1, the first compression spring 226 fixed at one end of the connecting block 222 is compressed as the sliding groove 224 slides, thereby driving the card block 221 to move in the groove on the mounting ring 21. When the card slot 173 moves to the card block 221, since the card slot 173 is a hole, the card block 221 cannot be squeezed. The first compression spring 226 rebounds after losing the squeezing of the card block 221, so that the card block 221 is clamped in the card slot 173, thereby fixing the card slot 173 that has been sleeved, and stably connecting the cable. Finally, when the cable connection is completed, the closing leaf 311 is squeezed out, and the second compression spring 312 rebounds after losing the squeezing of the closing leaf 311, so that the closing leaf 311 is tightly fitted to the cable, preventing dust in the environment from entering the welding head 171 through the connection between the connector 14 and the cable.
