Description

Technical Field

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

[0002] In power transmission and distribution networks, high-voltage cables are key carriers of electrical energy. The quality of their terminal connections is directly related to the safety and stability of power transmission. In complex power distribution scenarios, right-angle connections of high-voltage cables are often necessary. For example, in substations and distribution rooms, horizontal and vertical cables must be connected through terminal connections to form a 90° angle to accommodate spatial layout requirements. However, the existing connection method for right-angle high-voltage cable terminals still has many technical pain points. During the traditional connection process, operators need to manually adjust the ends of the horizontal and vertical cables to ensure that they are accurately aligned before fixing them. However, due to the inherent rigidity of high-voltage cables and the large diameter of the terminal heads, manual alignment is not only time-consuming and labor-intensive, but also difficult to ensure docking accuracy. Poor contact can easily lead to problems such as excessive resistance and localized heating, which can even cause safety accidents such as short circuits and breakdowns. At the same time, existing connection devices often require separate tightening of horizontal and vertical cables when securing cables, resulting in cumbersome operation steps. Uneven tightening force may cause the cable ends to shift, disrupting the adjusted docking state; insufficient tightening force can cause the cables to loosen during long-term operation due to vibration, thermal expansion, and contraction, affecting connection stability. Furthermore, some connection devices lack guidance and limiting mechanisms for the cable docking process, making it easy for the horizontal and vertical cable ends to misalign during tightening, further reducing connection reliability. Summary of the Invention

[0003] The present invention provides a high-voltage cable terminal head connection device to solve the problem in the prior art that it is time-consuming and labor-intensive to connect a ninety-degree corner cable end head.

[0004] In order to alleviate the above technical problems, the technical solution provided by the present invention is: A high-voltage cable terminal head connection device includes a fixing mechanism and a first driving mechanism; The fixing mechanism includes an L-shaped shell and a fixing frame sliding in the L-shaped shell, the fixing frame is threadedly connected to a screw, the end of the screw is rotatably connected to the L-shaped shell, and the L-shaped shell is plugged with a horizontal cable and a vertical cable; The first drive mechanism includes a first wedge connected to the fixed frame and a second wedge connected to the vertical cable; The fixing frame clamps the horizontal cable. When the screw is tightened, the first wedge drives the second wedge to move upward so that the vertical cable moves upward, and the fixing frame drives the horizontal cable to approach the vertical cable.

[0005] Furthermore, the fixing frame includes a rectangular frame, a bottom plate connected to the side of the rectangular frame, and a top plate connected to the upper part of the bottom plate through a vertical rod, the vertical cable is inserted in the middle of the rectangular frame, and the horizontal cable is inserted between the top plate and the bottom plate; The first wedge block is fixedly connected to the rectangular frame, and a hole cooperating with the second wedge block is opened on the upper part of the first wedge block on the rectangular frame, and a threaded hole cooperating with the screw rod is opened on the rectangular frame.

[0006] Furthermore, the horizontal cable is fixedly connected to a first end, the first end is fixedly connected to a first conductive rod, and the end of the first conductive rod is fixedly connected to a tapered plug rod; A second end is fixedly connected to the vertical cable, a second conductive rod is fixedly connected to the second end, and a conductive ring that cooperates with the conical plug rod is fixedly connected to the end of the second conductive rod. After the vertical cable moves upward, the conductive ring can be in a coaxial position with the conical plug rod.

[0007] Furthermore, the first driving mechanism further includes a hoop, and the second wedge is fixedly connected to the hoop.

[0008] Furthermore, it also includes a second driving mechanism, which includes two clamping plates that swing symmetrically on the top plate and the bottom plate. In the initial state, the two clamping plates are inclined in the direction away from the first end. When the fixed frame moves, the two clamping plates swing toward the horizontal cable, thereby clamping the horizontal cable.

[0009] Furthermore, push plates are slidably connected to the L-shaped shell near the top plate and the bottom plate, and a guide rod is fixedly connected to the push plate. A spring is sleeved on the guide rod, and a sliding hole that cooperates with the guide rod is opened in the L-shaped shell. The two ends of the spring are fixedly connected to the push plate and the L-shaped shell respectively. When the fixing frame slides, the ends of the two clamping plates abut against the push plates, so that the two clamping plates swing.

[0010] Furthermore, the second driving mechanism further comprises four cam posts, the top ends of the four cam posts being rotatably connected to the four corners of the top plate, and the bottom ends of the four cam posts being rotatably connected to the bottom plate; The ends of the four cam columns are fixedly connected to gears, and teeth that mesh with the gears are provided in the L-shaped shell. When the fixed frame moves and the clamping plate does not contact the push plate, the gears mesh with the teeth, so that the cam column rotates to push the horizontal cable to slide on the fixed frame toward the vertical cable, and after the clamping plate swings, the gear disengages from the teeth.

[0011] Furthermore, it also includes a locking mechanism, which includes a locking plate, a hole that matches the first conductive rod is opened on the locking plate, and the locking plate can lock the first conductive rod when sliding perpendicular to the axis of the first conductive rod.

[0012] Furthermore, a first nut is threadedly connected to the L-shaped shell, and an end of the first nut is rotatably connected to the locking plate. When the first nut rotates, it can drive the locking plate to slide perpendicular to the axis of the first conductive rod.

[0013] Furthermore, the locking mechanism further includes a second nut threadedly connected to the L-shaped shell, and when the second nut is tightened, the second nut can abut against the first end head.

[0014] The beneficial effects of the present invention are analyzed as follows: A high-voltage cable terminal head connection device includes a fixing mechanism and a first driving mechanism; the fixing mechanism includes an L-shaped shell and a fixing frame sliding in the L-shaped shell, the fixing frame is threadedly connected to a screw rod, the end of the screw rod is rotatably connected to the L-shaped shell, and a horizontal cable and a vertical cable are inserted into the L-shaped shell; the first driving mechanism includes a first wedge block connected to the fixing frame and a second wedge block connected to the vertical cable; the fixing frame clamps the horizontal cable, and when the screw rod is tightened, the first wedge block drives the second wedge block to move upward to move the vertical cable upward, and the fixing frame drives the horizontal cable close to the vertical cable.

[0015] When the cable ends are connected, the vertical cable and the horizontal cable are respectively inserted into the L-shaped shell, and the fixing frame is slidably connected in the L-shaped shell. The horizontal cable is inserted into the L-shaped shell and is clamped by the fixing frame. When the tightening screw is rotated, the fixing frame moves. At this time, the fixing frame drives the horizontal cable to approach the vertical cable. In addition, when the horizontal cable does not contact the vertical cable during the movement process, the first wedge on the fixing frame first contacts the second wedge on the vertical cable, and the first wedge drives the second wedge to move upward. When the flat part of the first wedge contacts the flat part of the second wedge, the vertical cable stops moving upward. At this time, the end of the vertical cable is in a position where it can contact the horizontal cable, and then, in the process of the fixing frame driving the horizontal cable to move, the end of the horizontal cable can contact the end of the vertical cable, thereby completing the right-angle high-voltage cable end connection.

[0022] Examples, such as Figure 1-Figure 7 As shown, a high-voltage cable terminal head connection device includes a fixing mechanism 100 and a first driving mechanism 200; the fixing mechanism 100 includes an L-shaped shell 110 and a fixing frame 140 sliding in the L-shaped shell 110, the fixing frame 140 is threadedly connected to a screw rod 141, the end of the screw rod 141 is rotatably connected to the L-shaped shell 110, and a horizontal cable 120 and a vertical cable 130 are inserted into the L-shaped shell 110; the first driving mechanism 200 includes a first wedge block 210 connected to the fixing frame 140 and a second wedge block 230 connected to the vertical cable 130; the fixing frame 140 clamps the horizontal cable 120, and 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 close to the vertical cable 130.

[0023] The working mechanism of the high-voltage cable terminal connection device provided in this embodiment is as follows: When connecting the cable ends, the vertical cable 130 and the horizontal cable 120 are respectively inserted into the L-shaped shell 110, and the fixing frame 140 is slidably connected to the L-shaped shell 110. The horizontal cable 120 is inserted into the L-shaped shell 110 and is clamped by the fixing frame 140. When the tightening screw 141 is rotated, the fixing frame 140 moves. At this time, the fixing frame 140 drives the horizontal cable 120 to approach the vertical cable 130. In addition, when the horizontal cable 120 does not contact the vertical cable 130 during the movement process, the first wedge 210 on the fixing frame 140 is first It first contacts the second wedge 230 on the vertical cable 130, and the first wedge 210 drives the second wedge 230 to move upward. When the plane part of the first wedge 210 contacts the plane part of the second wedge 230, the vertical cable 130 stops moving upward. At this time, the end of the vertical cable 130 is in a position to contact 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 high-voltage cable end connection.

[0024] Among the optional methods of this embodiment, the more preferred ones are: The fixing frame 140 includes a rectangular frame 142, a bottom plate 144 connected to the side of the rectangular frame 142, and a top plate 143 connected to the upper part of the bottom plate 144 through a vertical rod 145. The vertical cable 130 is inserted into the middle 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 to the rectangular frame 142, and a hole is provided on the upper part of the first wedge block 210 on the rectangular frame 142 to cooperate with the second wedge block 230, and a threaded hole is provided on the rectangular frame 142 to cooperate with the screw 141.

[0025] When the fixing frame 140 moves, the vertical cable 130 is pressed against the inner wall of the L-shaped shell 110 through the rectangular frame 142, and the first wedge block 210 supports the vertical cable 130 to prevent the vertical cable 130 from escaping from the L-shaped shell 110. The horizontal cable 120 is inserted between the top plate 143 and the bottom plate 144. The top plate 143 and the bottom plate 144 squeeze the horizontal cable 120, so that the fixing frame 140 can drive the horizontal cable 120 to move synchronously when it moves.

[0026] Among the optional methods of this embodiment, the more preferred ones are: A first end 121 is fixedly connected to the horizontal cable 120, a first conductive rod 122 is fixedly connected to the first end 121, and a conical plug 123 is fixedly connected to the end of the first conductive rod 122; a second end 131 is fixedly connected to the vertical cable 130, a second conductive rod 132 is fixedly connected to the second end 131, and a conductive ring 133 that cooperates with the conical plug 123 is fixedly connected to the end of the second conductive rod 132. After the vertical cable 130 moves upward, the conductive ring 133 can be in a coaxial position with the conical plug 123.

[0027] The first end 121 and the second end 131 can be connected to the horizontal cable 120 and the vertical cable 130 in an existing manner. For example, the cable end is inserted into the end, and then the cable and the end are locked by a clamp or screw. If there are multiple groups of wires inside the cable, multiple screws or clamps are used to fix the wire bundles to the end. For cables with multiple branch lines, multiple cylindrical tubes are provided in the end, so that the multiple branch lines are respectively plugged into the multiple cylindrical tubes, and then each wire bundle is fixed in the corresponding cylindrical tube with a clamp or screw, and the conductive rod is fixedly inserted into the cylindrical tube so that each wire bundle can be electrically connected to the conductive rod. After the connection between the cable and the end is completed, the fixing frame 140 is controlled to slide so that the conductive ring 133 moves upward, and then the tapered rod 123 approaches the conductive ring 133 and is inserted into the conductive ring 133, completing the electrical connection between the horizontal cable 120 and the vertical cable 130. Since the tapered rod 123 has a taper, even if there is a slight position deviation between the conductive ring 133 and the tapered rod 123, it does not affect the insertion of the tapered rod 123 into the conductive ring 133.

[0028] Among the optional methods of this embodiment, the more preferred ones are: The first driving mechanism 200 further includes a hoop 220 , and the second wedge 230 is fixedly connected to the hoop 220 .

[0029] The hoop 220 can be configured to be fixedly connected to the second end 131, or the hoop 220 can be installed on the vertical cable 130 so that the hoop 220 is close to the second end 131, so that the vertical cable 130 is not easily bent when the second wedge block 230 is lifted and moved upward, ensuring that the conductive ring 133 can rise to the required height.

[0030] Regarding the structure of the second driving mechanism 300, specifically: The second driving mechanism 300 includes two clamps 340 that swing symmetrically on the top plate 143 and the bottom plate 144. In the initial state, the two clamps 340 are inclined in the direction away from the first end 121. When the fixing frame 140 moves, the two clamps 340 swing toward the horizontal cable 120, thereby clamping the horizontal cable 120.

[0031] The setting of the two clamps 340 enhances the clamping force of the fixing frame 140 on the horizontal cable 120, ensuring that the fixing frame 140 can stably drive the horizontal cable 120 to move. In the initial state, the two clamps 340 close to the end of the horizontal cable 120 swing toward the direction away from the first end 121. After the fixing frame 140 moves, the two clamps 340 both swing and approach the horizontal cable 120. At this time, the two clamps 340 can firmly clamp the horizontal cable 120.

[0032] Among the optional methods of this embodiment, the more preferred ones are: A push plate 350 is slidably connected to the L-shaped shell 110 near the top plate 143 and the bottom plate 144. A guide rod 360 is fixedly connected to the push plate 350, and a spring 370 is sleeved on the guide rod 360. A sliding hole that cooperates with the guide rod 360 is opened in the L-shaped shell 110. The two ends of the spring 370 are fixedly connected to the push plate 350 and the L-shaped shell 110 respectively. When the fixing frame 140 slides, the ends of the two splints 340 abut against the push plate 350, so that the two splints 340 swing.

[0033] When the fixing frame 140 moves, the two clamps 340 move synchronously, and the fixing frame 140 slides relative to the L-shaped shell 110. As the fixing frame 140 moves, the ends of the two clamps 340 away from the horizontal cable 120 can respectively contact the corresponding push plates 350. The push plates 350 block the ends of the clamps 340, so that the clamps 340 can swing and clamp the horizontal cable 120. As the fixing frame 140 continues to move, the spring 370 is compressed, ensuring that the resistance applied to the clamps 340 increases without affecting the movement of the fixing frame 140.

[0034] Among the optional methods of this embodiment, the more preferred ones are: The second drive mechanism 300 also includes four cam columns 310, the top ends of the four cam columns 310 are respectively rotatably connected to the four corners of the top plate 143, and the bottom ends are rotatably connected to the bottom plate 144; the ends of the four cam columns 310 are fixedly connected to gears 320, and teeth 330 engaged with the gears 320 are provided in the L-shaped shell 110. When the fixing frame 140 moves and the splint 340 does not contact the push plate 350, the gear 320 engages with the teeth 330, so that the cam column 310 rotates to push the horizontal cable 120 on the fixing frame 140 to slide toward the vertical cable 130, and after the splint 340 swings, the gear 320 disengages from the teeth 330.

[0035] In the initial stage when the horizontal cable 120 is not clamped by the clamping plate 340, in order to prevent the top plate 143 and the bottom plate 144 of the fixing frame 140 from directly contacting and pushing the first end 121 when the fixing frame 140 moves, so that the first end 121 may be separated from the horizontal cable 120, the clamping plate 340 is not released from the pushing plate 350 when the fixing frame 140 starts to move. At this time, the gear 320 is in a state of meshing with the teeth 330, so that the two groups of cam columns 310 on both sides of the horizontal cable 120 rotate. The two groups of rotating cam columns 310 rely on the squeezing friction force generated by the contact with the horizontal cable 120 during rotation to push the horizontal cable 120 to slide relative to the fixing frame 140, so that the first end 121 can not contact the top plate 143 and the bottom plate 144, thereby preventing the first end 121 from being pushed away from the horizontal cable 120; As the fixing bracket 140 continues to move, the gear 320 no longer meshes with the teeth 330 , ensuring that when the clamping plate 340 clamps the horizontal cable 120 , the cam column 310 will not be blocked from rotating, causing the fixing bracket 140 to be stuck.

[0036] Regarding the structure of the locking mechanism 400, specifically: The locking mechanism 400 includes a locking plate 420 . A hole is formed on the locking plate 420 to match the first conductive rod 122 . The locking plate 420 can lock the first conductive rod 122 when sliding perpendicularly to the axis of the first conductive rod 122 .

[0037] After rotating the screw 141 to connect the horizontal cable 120 and the vertical cable 130, a gasket is added between the nut of the screw 141 and the rectangular frame 142 so that later vibration will not cause the screw 141 to rotate. Then, the locking plate 420 is controlled to move vertically so that the inner wall of the hole on the locking plate 420 abuts against the first conductive rod 122, thereby completing the locking of the first conductive rod 122.

[0038] Among the optional methods of this embodiment, the more preferred ones are: A first nut 410 is threadedly connected to the L-shaped shell 110 . The end of the first nut 410 is rotatably connected to the locking plate 420 . When the first nut 410 rotates, it can drive the locking plate 420 to slide perpendicular to the axis of the first conductive rod 122 .

[0039] The end of the first nut 410 is rotatably connected to the side wall of the locking plate 420 , and a bearing connection can be used therebetween, so that the first nut 410 can drive the locking plate 420 to move upward or downward when it rotates.

[0040] Among the optional methods of this embodiment, the more preferred ones are: The locking mechanism 400 further includes a second nut 430 threadedly connected to the L-shaped housing 110 . When the second nut 430 is tightened, the second nut 430 can abut against the first end 121 .

[0041] After rotating the first nut 410 to lock the first conductive rod 122, rotate the second nut 430 so that the end of the second nut 430 abuts against the first end 121, pressing the first end 121 against the fixing frame 140, thereby completing the fixing of the cable.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
