Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cable connection, in particular to a high-voltage cable terminal head connecting device. BACKGROUND

[0002] In the power transmission and distribution network of the power system, the high-voltage cable as the key carrier of power transmission, the connection quality of its terminal head is directly related to the safety and stability of power transmission. Especially in some complex power distribution scenarios, it is often necessary to realize the right-angle connection of high-voltage cables, for example, in the cable arrangement of transformer substations and power distribution rooms, the horizontal and vertical cables need to be connected through the terminal head to form a 90° corner to adapt to the space layout requirements.

[0003] However, the existing connection mode of the right-angle high-voltage cable terminal head still has many technical problems. In the traditional connection process, the operator needs to manually adjust the end positions of the horizontal and vertical cables to ensure accurate butt joint before fixing. However, due to the rigidity of the high-voltage cable itself and the large diameter of the terminal head part, manual alignment is not only time-consuming and laborious, but also difficult to ensure the butt joint accuracy, which may easily cause excessive resistance, local heating and other problems due to poor contact, and even cause short circuit, breakdown and other safety accidents in severe cases.

[0004] At the same time, the existing connecting device often needs to separately fasten the horizontal and vertical cables when fixing the cables, which is complicated. If the fixing force is uneven, it may cause the cable end to deviate, damaging the adjusted butt joint state; and if the fixing force is insufficient, it may cause the cable to loosen due to vibration, thermal expansion and contraction and other factors in long-term operation, affecting the connection stability. In addition, some connecting devices lack the guiding and limiting mechanism for the cable butt joint process, and the end positions of the horizontal and vertical cables may be misaligned during the fastening process, further reducing the connection reliability.

[0039] Embodiments, such as Figures 1-7As shown in the figure, the high-voltage cable terminal head connecting device comprises a fixing mechanism 100 and a first driving mechanism 200; the fixing mechanism 100 comprises an L-shaped shell 110 and a fixing frame 140 sliding in the L-shaped shell 110, the fixing frame 140 is screw-connected with a screw rod 141, the end of the screw rod 141 is rotationally connected with the L-shaped shell 110, the L-shaped shell 110 is inserted with a horizontal cable 120 and a vertical cable 130; the first driving mechanism 200 comprises a first wedge block 210 connected with the fixing frame 140 and a second wedge block 230 connected with the vertical cable 130; the fixing frame 140 clamps the horizontal cable 120, when the screw rod 141 is tightened, the first wedge block 210 drives the second wedge block 230 to move upward to make the vertical cable 130 move upward, and the fixing frame 140 drives the horizontal cable 120 to move close to the vertical cable 130.

[0040] The working mechanism of the high-voltage cable terminal head connecting device provided by the embodiment is as follows:

[0041] When the cable terminal head is connected, the vertical cable 130 and the horizontal cable 120 are respectively inserted into the L-shaped shell 110, the fixing frame 140 is slidingly connected in the L-shaped shell 110, the horizontal cable 120 is inserted into the L-shaped shell 110 and clamped by the fixing frame 140, the fixing frame 140 moves when the screw rod 141 is rotated and tightened, at this time, the fixing frame 140 drives the horizontal cable 120 to move close to the vertical cable 130, in addition, when the horizontal cable 120 moves without contacting the vertical cable 130, the first wedge block 210 on the fixing frame 140 first contacts the second wedge block 230 on the vertical cable 130, and the first wedge block 210 drives the second wedge block 230 to move upward, when the planar part of the first wedge block 210 contacts the planar part of the second wedge block 230, the vertical cable 130 stops moving upward, at this time, the end of the vertical cable 130 is in a position capable of contacting the horizontal cable 120, and then in the process of the fixing frame 140 driving the horizontal cable 120 to move, the end of the horizontal cable 120 can contact the end of the vertical cable 130, thereby completing the right-angle type high-voltage cable terminal head connection.

[0042] In the optional mode of the embodiment, the more preferred is as follows:

[0043] The fixing frame 140 comprises a rectangular frame 142, a bottom plate 144 connected with the side of the rectangular frame 142, a top plate 143 connected with the upper part of the bottom plate 144 through a vertical rod 145, the vertical cable 130 is inserted in the middle part of the rectangular frame 142, and the horizontal cable 120 is inserted between the top plate 143 and the bottom plate 144; the first wedge block 210 is fixedly connected with the rectangular frame 142, and a hole matched with the second wedge block 230 is formed in the upper part of the rectangular frame 142 above the first wedge block 210, and a threaded hole matched with the screw rod 141 is formed in the rectangular frame 142.

[0044] The fixed frame 140 presses the vertical cable 130 against the inner wall of the L-shaped shell 110 through the rectangular frame 142 when moving, and cooperates with the first wedge 210 to lift the vertical cable 130, thereby preventing the vertical cable 130 from being separated from the L-shaped shell 110. The horizontal cable 120 is inserted between the top plate 143 and the bottom plate 144, and the top plate 143 and the bottom plate 144 form a pressing force on the horizontal cable 120, so that the fixed frame 140 can drive the horizontal cable 120 to move synchronously when moving.

[0045] In an optional mode of the embodiment, the following is preferred:

[0046] The horizontal cable 120 is fixedly connected with a first end head 121, the first end head 121 is fixedly connected with a first conductive rod 122, and the end of the first conductive rod 122 is fixedly connected with a tapered plug rod 123. The vertical cable 130 is fixedly connected with a second end head 131, the second end head 131 is fixedly connected with a second conductive rod 132, and the end of the second conductive rod 132 is fixedly connected with a conductive ring 133 cooperating with the tapered plug rod 123. After the vertical cable 130 is moved upward, the conductive ring 133 can be in a coaxial position with the tapered plug rod 123.

[0047] The connection mode of the first end head 121 and the second end head 131 with the horizontal cable 120 and the vertical cable 130 can be in the existing mode, such as inserting the end of the cable into the end head, and then locking the cable with the end head by using a hoop or a screw. If the cable has multiple sub-wires inside, multiple screws or hoops are used to fix the wire harnesses on the end head. For cables with multiple sub-wires, multiple cylindrical barrels are provided in the end head, so that multiple sub-wires are inserted into the multiple cylindrical barrels, and then hoops or screws are used to fix each wire harness in the corresponding cylindrical barrel. The conductive rod is fixedly inserted into the cylindrical barrel, so that each wire harness can be electrically connected with the conductive rod.

[0048] After the connection of the cable and the end head is completed, the fixed frame 140 is controlled to slide, so that the conductive ring 133 moves upward, and then the tapered plug rod 123 approaches the conductive ring 133 and is inserted into the conductive ring 133, thereby completing the electrical connection of the horizontal cable 120 and the vertical cable 130. Since the tapered plug rod 123 has a taper, even if there is a slight positional deviation between the conductive ring 133 and the tapered plug rod 123, it does not affect the insertion of the tapered plug rod 123 into the conductive ring 133.

[0049] In an optional mode of the embodiment, the following is preferred:

[0050] The first driving mechanism 200 further comprises a hoop 220, and the second wedge 230 is fixedly connected to the hoop 220.

[0051] The hoop 220 can be fixedly connected with the second end head 131, or can be installed close to the second end head 131 when the hoop 220 is installed on the vertical cable 130, so that the vertical cable 130 is not easy to bend when the second wedge block 230 is lifted and moved upward, and the height required for the conductive ring 133 to rise is ensured.

[0052] Regarding the structure of the second driving mechanism 300, specifically:

[0053] The second driving mechanism 300 includes two clamping plates 340 symmetrically swinging on the top plate 143 and the bottom plate 144, which are initially inclined away from the first end head 121. When the fixed frame 140 moves, the two clamping plates 340 swing towards the horizontal cable 120, thereby clamping the horizontal cable 120.

[0054] The arrangement of the two clamping plates 340 enhances the clamping force of the fixed frame 140 on the horizontal cable 120, ensuring that the fixed frame 140 can stably drive the horizontal cable 120 to move. In the initial state, the end of the two clamping plates 340 close to the horizontal cable 120 swings away from the first end head 121. After the fixed frame 140 moves, both clamping plates 340 swing and approach the horizontal cable 120, at which time the two clamping plates 340 can firmly clamp the horizontal cable 120.

[0055] In an optional manner of the embodiment, it is more preferable that:

[0056] The L-shaped shell 110 is slidably connected with a push plate 350 close to the top plate 143 and the bottom plate 144, the push plate 350 is fixedly connected with a guide rod 360, the guide rod 360 is sleeved with a spring 370, the L-shaped shell 110 is provided with a sliding hole matched with the guide rod 360, and the two ends of the spring 370 are fixedly connected with the push plate 350 and the L-shaped shell 110. When the fixed frame 140 slides, the end portions of the two clamping plates 340 abut against the push plate 350, so that the two clamping plates 340 swing.

[0057] When the fixed frame 140 moves, the two clamping plates 340 move synchronously, the fixed frame 140 slides relative to the L-shaped shell 110, and with the movement of the fixed frame 140, the end portions of the two clamping plates 340 away from the horizontal cable 120 can respectively contact the corresponding push plates 350. The push plates 350 block the end portions of the clamping plates 340, so that the clamping plates 340 can swing and clamp the horizontal cable 120. With the continuous movement of the fixed frame 140, the spring 370 is compressed, ensuring that the resistance applied to the clamping plates 340 increases while not affecting the movement of the fixed frame 140.

[0058] In an optional manner of the embodiment, it is more preferable that:

[0059] The second driving mechanism 300 further comprises four cam columns 310, the top ends of the four cam columns 310 are rotationally connected to the four corners of the top plate 143 respectively, and the bottom ends are rotationally connected to the bottom plate 144; the end portions of the four cam columns 310 are fixedly connected with gear wheels 320, and the L-shaped shell 110 is provided with gear teeth 330 meshing with the gear wheels 320; when the fixed frame 140 moves and the clamping plates 340 do not contact the push plate 350, the gear wheels 320 mesh with the gear teeth 330, so that the cam columns 310 rotate to push the horizontal cable 120 to slide on the fixed frame 140 in the direction of the vertical cable 130, and after the clamping plates 340 swing, the gear wheels 320 are disengaged from the gear teeth 330.

[0060] In the initial stage when the horizontal cable 120 is not clamped by the clamping plates 340, in order to prevent the top plate 143 and the bottom plate 144 of the fixed frame 140 from directly contacting and pushing the first end 121 to make the first end 121 possibly disengaged from the horizontal cable 120 when the fixed frame 140 moves, the clamping plates 340 do not release the push plate 350 when the fixed frame 140 starts to move, at this time, the gear wheels 320 are in the meshing state with the gear teeth 330, so that the two groups of cam columns 310 located on both sides of the horizontal cable 120 rotate, and the two groups of rotating cam columns 310 can push the horizontal cable 120 to slide relative to the fixed frame 140 by relying on the extrusion friction force generated by the contact between the rotating cam columns 310 and the horizontal cable 120, so that the first end 121 can not contact the top plate 143 and the bottom plate 144, thereby avoiding that the first end 121 is pushed to disengage from the horizontal cable 120;

[0061] With the continuous movement of the fixed frame 140, the gear wheels 320 are no longer meshed with the gear teeth 330, so that when the clamping plates 340 clamp the horizontal cable 120, the rotating of the cam columns 310 is not blocked, and the fixed frame 140 is not stuck.

[0062] Regarding the structure of the locking mechanism 400, in particular:

[0063] The locking mechanism 400 comprises a locking plate 420, a hole for cooperating with the first conductive rod 122 is formed in the locking plate 420, and the locking plate 420 can lock the first conductive rod 122 when sliding perpendicular to the axis of the first conductive rod 122.

[0064] After the horizontal cable 120 and the vertical cable 130 are connected by the rotating screw rod 141, a gasket is added between the nut of the screw rod 141 and the rectangular frame 142, so that the later vibration will not cause the screw rod 141 to rotate, and then the vertical movement of the locking plate 420 is controlled, so that the inner wall of the hole in the locking plate 420 abuts against the first conductive rod 122, and the locking of the first conductive rod 122 is completed.

[0065] In the optional mode of the embodiment, the more preferred is:

[0066] The first nut 410 is threadedly connected to the L-shaped shell 110, and the end of the first nut 410 is rotatably connected to the locking plate 420, so that the first nut 410 can drive the locking plate 420 to slide perpendicularly to the axis of the first conductive rod 122 when the first nut 410 is rotated.

[0067] The end of the first nut 410 is rotatably connected to the side wall of the locking plate 420, and a bearing can be used therebetween, so that the first nut 410 can drive the locking plate 420 to move upward or downward when the first nut 410 is rotated.

[0068] In an alternative embodiment of the present embodiment, the following is preferred:

[0069] The locking mechanism 400 further comprises a second nut 430 threadedly connected to the L-shaped shell 110, and the second nut 430 can abut against the first end head 121 when the second nut 430 is tightened.

[0070] After the first conductive rod 122 is locked by rotating the first nut 410, the second nut 430 is rotated to make the end of the second nut 430 abut against the first end head 121, so as to press the first end head 121 against the fixing frame 140, thereby completing the fixation of the cable.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit the same; although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions recorded in the above embodiments can still be modified, or some or all of the technical features can be replaced by equivalents; and such modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
