Description

Technical Field

[0001] The utility model relates to the technical field of cable docking equipment, in particular to a single-core connector. Background Art

[0002] High voltage connectors, also known as high voltage cable connectors, are suitable for connecting power cable circuits in coal mining tunnels underground in coal mines. They are also suitable for laying cables in other underground excavation operations. They are used to connect the two ends of the cable for mutual plugging.

[0003] In the prior art, for example, the Chinese patent announcement number: CN220253533U discloses a single-core high-voltage connector, including a butt-joint tube, a plug and a rubber support tube, wherein two plugs are provided, and the two plugs are symmetrically installed at the two ends of the butt-joint 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-joint 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 the present 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, thereby avoiding poor contact.

[0004] Although the above scheme has the advantages as mentioned above, the disadvantage of the above scheme is that although the plug end can be inserted into the connecting tube and squeezed with the conical extrusion head, the plug end is bent 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 avoiding poor contact. However, when the cable is connected to the single-core connector, the cable is easily pulled in different directions, so that the cable end is prone to cracking, which may cause leakage and cause safety accidents, making the single-core connector less safe. In addition, since it is used underground in a coal mine, when the single-core connector is not in use, dust in the coal mine is easy to enter the connection of the single-core connector, which may cause poor contact of the single-core connector.

The interface 101 of the device body 1 is then manually rotated by the knob 206. Under the action of the threaded cooperation between the knob 206 and the hollow threaded tube 205, the knob 206 can be moved to one side along the outer surface of the hollow threaded tube 205. When it moves to a certain distance, the knob 206 contacts and squeezes the elastic sheet 207, so that the elastic sheet 207 drives the rubber gasket 208 to move toward the middle, clamping and fixing the cable. Under the cooperation of the compression spring 203, when the cable is pulled in different directions, it can play a certain buffering role, so that In order to avoid the cable from cracking due to pulling and to avoid leakage of the cable, the safety of the device is improved. When the cable is taken out from the interface 101 of the single-core connector body 1 and the device is not needed, the shielding piece 306 and the rubber block 307 are moved to a certain distance from the end of the single-core connector body 1 by pushing the movable rod 2 301 to one side. Under the reset force of the torsion spring 304, the shielding piece 306 and the rubber block 307 can be moved to the front of the interface 101 of the single-core connector body 1. At this time, the movable rod 2 301 is released to make the shielding piece 306 and the rubber block 307 have a certain distance from the end of the single-core connector body 1. Under the restoring force of the second compression spring 302, it returns to its original position, and synchronously drives the shielding piece 306 and the rubber block 307 to move toward the position of the interface 101, so that the rubber block 307 is inserted into the interior of the interface 101 and squeezes the rubber ring 308 to a certain extent, so that the interface 101 of the single-core connector body 1 can be blocked, so that when the single-core connector body 1 is not used for a long time, the dust in the coal mine cannot enter the interface 101 of the single-core connector body 1, thereby avoiding poor contact of the single-core connector body 1.
