Description

Technical Field

[0001] The utility model relates to the technical field of cable plug-in devices, in particular to an oil-immersed insulation type quick plug-in high-voltage cable plug-in device. Background Art

[0002] High-voltage cable is a type of power cable, which refers to a power cable used to transmit power between 1kv-1000kv. It is mostly used in power transmission and distribution. Some high-voltage cables are equipped with oil-impregnated paper on the outside, which is impregnated with an impregnating agent after vacuum drying to achieve insulation. Then a plug-in device is set at one end of the high-voltage cable to connect the two sections of the cable.

[0003] For example, a cable plug device with publication number CN220456789U includes a housing and a clamping member. The clamping member of the cable plug device of the utility model can automatically clamp the cables connected in each plug hole under the action of an elastic member. The power lead cable of the electrical equipment and the power supply cable of the power source only need to be inserted into the plug hole to realize stable transmission of electricity, thereby avoiding cable falling off or poor contact, and improving the safety of underground coal mine power supply operations;

[0004] The cable plug-in device inserts the power supply cable into the plug-in hole of the shell, and then compresses it through the elastic member and the clamping member to achieve plug-in. However, the compression is only performed through the elastic force of the elastic member. When the two sections of the power supply cable are pulled by external force, the plug-in position is prone to loosening, and even separation occurs in severe cases. Therefore, the firmness of the plug-in is not good. In view of this, it is very necessary to design an oil-immersed insulated quick-plug high-voltage cable plug-in device to solve this problem. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an oil-immersed insulated quick-plug high-voltage cable connector, which solves the problem that the existing cable connector only uses the elastic force of an elastic part to perform compression. When the two sections of the cable are pulled by external force, the connection is prone to loosening, and even separation may occur in severe cases, so the connection is not firm.

[0006] To achieve the above purpose, the utility model is implemented by the following technical solutions: an oil-immersed insulated quick-plug high-voltage cable plug-in device, comprising a socket and a connecting plate, the insides of the left and right sockets are fixedly connected with connecting plates, the outside of the connecting plate is fixedly connected with a high-voltage cable, the inner outer wall of the high-voltage cable is connected with a cover plate, and the cover plate is threadedly connected to the socket through a plurality of bolts, the inside and outer walls of the socket are respectively installed with a plug-in mechanism and a fixing mechanism, and the inner sides of the left and right sockets are bonded with rubber rings;

[0007] The plug-in mechanism includes a first plug rod and a second plug rod respectively fixed to the outer walls of the left and right connecting plates, and the first plug rod is plugged into the second plug rod. The upper and lower outer walls of the left socket are fixed with vertical plates, and the right side of the vertical plate is fixed with a pair of arc plates. The inner sides of adjacent arc plates are rotatably connected with baffles through a rotating shaft. A card block fixed to the outer wall of the right socket is installed on the right side of the baffle, and the inner wall of the groove of the card block is gap-matched with the outer wall of the right end of the baffle.

[0008] Preferably, sliding rods are slidably engaged at the sliding grooves of the upper and lower baffles.

[0009] Preferably, the fixing mechanism comprises a horizontal plate fixedly connected to the vertical plate, and the internal thread of the horizontal plate is connected to a screw rod, the inner sides of the upper and lower screw rods are rotatably connected to rectangular blocks, and the rectangular blocks are fixedly connected to the sliding rod.

[0010] Preferably, a handle is fixedly connected to the outer side of the pair of screw rods.

[0011] Beneficial Effects

[0012] The utility model provides an oil-immersed insulated quick-plug high-voltage cable connector, which has the following beneficial effects:

[0013] The cover plate and the high-voltage cable can be driven to move through the socket. When the two sockets are relative to each other, the first plug rod will be inserted into the second plug rod to achieve preliminary plug-in fixation. Then, the handle is turned to drive the screw rod to rotate. The screw rod can move through the cross plate, so that the screw rod can drive the rectangular block to move, so that the rectangular block drives the slide rod to move in the slide groove of the baffle. At the same time, the slide rod cooperates with the arc block to drive the baffle to rotate, so that the right end of the baffle enters the groove of the card block, and the two sockets can be further fixed by the baffle and the card block. In this way, even if the two ends of the two high-voltage cables are pulled by external force, the connection is not easy to loosen or separate, so the firmness of the plug-in is better.
