[0002] A cable joint is a mechanical protection device used to connect two or more cables. After the existing cable joints connect the two cables together, they need to use locking nuts to fix the cables inside the cable joints to prevent the cables from running out of the cable joints. However, in windy weather, both cables will be blown by the wind and shake. During the shaking of the cables, due to the different lengths of the two cables and the uncontrollable wind force from the outside, when one cable is reset during the shaking of the two cables, the other cable may still be shaking.

DETAILED DESCRIPTION

[0026] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] When encountering strong winds, the two cables connected together by the cable connector will be blown by the wind and shake. During the shaking process of the cables, due to the different lengths of the two cables and the uncontrollable external wind force, when one cable is reset, the other cable may still be shaking, which will cause damage to the insulation near the ends of the two cables fixed by the locking nuts. If this continues for a long time, it may even cause the cable cores of the two cables to break.

[0028] Example 1: A cable connector with an overload protection structure, please refer to Figure 1-Figure 4As shown, it includes two symmetrically distributed sleeves 101, which are hinged to each other, and the lengths of the parts of the two cables located in the sleeves 101 are greater than half of the length of the sleeves 101 to adapt to the shaking of the cables, and two connecting tubes 102 symmetrically distributed on the left and right are fixedly connected to the middle part of the rear sleeve 101, and the back sides of the two symmetrically distributed connecting tubes 102 are threadedly connected with locking nuts 103, and the opposite sides of the two symmetrically distributed connecting tubes 102 are slidably connected with contact members 104, and the two symmetrically distributed sleeves 101 are slidably connected with bolts 105, and the bolts 105 are threadedly connected with nuts 106, and the bolts 105 and the nuts 106 are used to fix the two sleeves 101 together, and the sleeves on the rear side Two hydraulic shells 107 symmetrically distributed on the left and right are fixedly connected in 101, and the hydraulic shells 107 are slidably connected to the connecting pipes 108. Both sleeves 101 are slidably connected to the connecting pipes 108. One end of the connecting pipe 108 located outside the sleeve 101 is threadedly connected to a locking nut 109. The connecting pipe 108 is fixedly connected to a piston plate 110, and the piston plate 110 is slidably connected to the adjacent hydraulic shells 107, and an elastic member 111 is connected between the piston plate 110 and the adjacent hydraulic shells 107. Two buffer protection components symmetrically distributed on the left and right are arranged in the sleeve 101 on the rear side. The buffer protection components are used to provide further buffering for the adjacent cables. An overload protection mechanism for providing overload protection for the two cables is arranged in the middle of the sleeve 101 on the rear side.

[0029] Please refer to Figure 3 and Figure 4 As shown, the buffer protection component includes a hydraulic shell 201, which is fixedly connected to one side of the rear sleeve 101. The hydraulic shell 201 is filled with hydraulic oil. The hydraulic shell 201 is slidably connected to the adjacent connecting pipe 2 108. The connecting pipe 2 108 is fixedly connected to a slide plate 202 that is slidably connected to the adjacent hydraulic shell 201. Four circumferentially distributed fixing members 203 are fixedly connected to the side of the hydraulic shell 201 away from the connecting pipe 1 102. The slide plate 202 is provided with four circumferentially distributed through holes. The fixing member 203 is configured as a cone, and the tip of the fixing member 203 faces the adjacent slide plate 202. In the process of the slide plate 202 sliding toward the adjacent fixing member 203, the flow area of ​​the through hole on the slide plate 202 gradually decreases, thereby increasing the resistance to the flow of hydraulic oil.

[0030] When the connector is used to connect two cables, the nut 106 is firstly screwed to separate the nut 106 from the bolt 105, and then the user removes the bolt 105 and separates the two sleeves 101 (please refer to Figure 2), then the user screws the two locking nuts 109 and the two locking nuts 103 until the minimum cross-sectional area of ​​the connecting tube 102 and the connecting tube 108 is enough for the cable to pass through, the user stops screwing the two locking nuts 109 and the two locking nuts 103, then the user passes the two cables through the adjacent locking nuts 109, the hydraulic shell 107 and the locking nuts 103 respectively into the adjacent connecting tube 102, the user connects the cable to the adjacent contact piece 104, then the user screws the two locking nuts 109 and the two locking nuts 103 in reverse, so as to fix the cable in the adjacent connecting tube 102 and the adjacent connecting tube 108, then the staff closes the two sleeves 101 together, inserts the bolt 105 into the two sleeves 101, and tightens the nut 106 on the bolt 105, so as to fix the two sleeves 101.

[0031] After the above-mentioned installation operation is completed, the device can be put into use. During the use of the device, when the wind blows the cable to shake, the cable blown by the wind drives the adjacent connecting tube 2 108 to move away from the connecting tube 1 102, and the connecting tube 2 108 drives the adjacent piston plate 110 to move and compresses the adjacent elastic member 111. After being compressed, the elastic member 111 exerts a reverse force on the piston plate 110, thereby slowing down the movement trend of the connecting tube 2 108, thereby buffering the shaking of the cable.

[0032] During the movement of the connecting tube 108, the connecting tube 108 drives the adjacent slide 202 to move synchronously. The slide 202 moves to squeeze the hydraulic oil in the hydraulic shell 201, so that the hydraulic oil in the hydraulic shell 201 moves to the side with increased volume through the through hole on the slide 202, thereby further slowing down the movement trend of the connecting tube 108 and further buffering the shaking of the cable.

[0033] During the movement of the slide plate 202, as the fixing member 203 gradually enters the adjacent through holes on the slide plate 202, the flow area of ​​the through holes on the slide plate 202 gradually decreases, thereby slowing down the flow speed of the hydraulic oil in the hydraulic shell 201, thereby further slowing down the movement trend of the connecting pipe 2 108 and further buffering the shaking of the cable.

[0034] Example 2: Based on Example 1, please refer to Figure 5 and Figure 6As shown, the overload protection mechanism includes a fixing frame 301, which is fixed to the middle part of the rear sleeve 101, and the fixing frame 301 is rotatably connected to two rotating plates 302 symmetrically distributed on the left and right, and an elastic member 303 is connected between the rotating plate 302 and the fixing frame 301, and the elastic member 303 is a torsion spring, and the rotating plate 302 is slidably connected to a sliding rod 304, and the sliding rod 304 is slidably connected to the fixing frame 301, and an elastic member 305 is connected between the sliding rod 304 and the adjacent rotating plate 302, and the elastic member 305 is a spring and is initially in a compressed state, and a temperature sensing rope 306 is connected between the symmetrically distributed sliding rods 304, and the temperature sensing rope 306 contacts the contact piece 104 on the right side and monitors the temperature of the contact piece 104 on the right side, and when the temperature of the contact piece 104 on the right side rises to the point of about damaging the cable, the temperature sensing rope 306 itself will The fuse is blown, the contact piece 104 on the right is fixedly connected to the limiting frame 1 307, the connecting tube 102 on the left is slidably connected to the limiting frame 2 308, the limiting frame 1 307 and the limiting frame 2 308 are limitedly matched, the limiting frame 2 308 is squeezed and matched with the rotating plate 302 on the left, an elastic piece 4 309 is connected between the limiting frame 2 308 and the adjacent connecting tube 1 102, and the elastic piece 4 309 is an elastic plate, and an elastic piece 5 310 is connected between the contact piece 104 on the right and the adjacent connecting tube 102, and the elastic piece 5 310 is a tension spring and is initially in a stretched state.

[0035] During the process of power transmission between the two cables, the temperature of the two cables gradually increases, but the temperature sensing rope 306 is always in contact with the right contact piece 104 and monitors the temperature of the right contact piece 104. At this time, there are the following two monitoring results:

[0036] Result 1: The current passing through the two cables is normal and does not exceed the normal operating range. At this time, the temperature of the cables is not high enough to melt the temperature sensing rope 306 , so the temperature sensing rope 306 is still working normally to monitor the temperature of the right contact 104 .

[0037] Result 2: Because the load in the circuit connected by the two cables is too large, the current flowing in the two cables exceeds the normal working range. At this time, the two cables will heat up abnormally, and the temperature of the two contact pieces 104 connecting the two cables will also heat up abnormally. When the temperature of the two cables rises to the point where they are about to cause damage to the cables, the temperature of the right contact piece 104 rises to the temperature of the melting temperature rope 306. After the temperature rope 306 is melted, under the action of the two elastic members 305, the two slide bars 304 move back to back and slide out of the adjacent rotating plate 302. When the slide bar 304 slides out of the adjacent rotating plate 302, the slide bar 304 The limit on the adjacent rotating plates 302 is released, and then under the action of the two elastic members 303, the two rotating plates 302 rotate, and the rotating plate 302 on the left rotates to squeeze the limit frame 308, so that the limit frame 308 moves backward and squeezes the elastic member 4 309. The limit frame 308 moves backward to release the limit cooperation with the limit frame 1 307. At this time, under the action of the two elastic members 310, the two contact members 104 move back to back and no longer contact, and the passage between them is released, thereby disconnecting the power transmission between the two cables. In this way, the circuit is disconnected to protect the cables, preventing the two cables from abnormally heating up and causing damage to the two cables.

[0038] Example 3: Based on Example 2, please refer to Figure 5 and Figure 7 As shown, it also includes two fluid exchange tubes 401 symmetrically distributed in the upper and lower parts, and the left and right ends of the two symmetrically distributed fluid exchange tubes 401 are respectively fixed to the adjacent hydraulic shell 107, and the left and right ends of the two fluid exchange tubes 401 are respectively connected with the adjacent hydraulic shell 107, and the two hydraulic shells 107 and the two fluid exchange tubes 401 are filled with hydraulic oil, and the connection between the hydraulic shell 107 and the two fluid exchange tubes 401 is located on both sides of the inner piston plate 110.

[0039] During the movement of the piston plate 110, the piston plate 110 moves and squeezes the hydraulic oil in the adjacent hydraulic shell 107. At this time, taking the piston plate 110 on the left side as an example, the hydraulic oil in the left hydraulic shell 107 located on the left side of the adjacent piston plate 110 enters the upper fluid exchange tube 401, and the hydraulic oil entering the upper fluid exchange tube 401 then enters the cavity in the right hydraulic shell 107 located on the left side of the adjacent piston plate 110, so that the right piston plate 110 moves to the right, and the hydraulic oil in the right hydraulic shell 107 located on the right side of the adjacent piston plate 110 is squeezed into the lower fluid exchange tube 401, and the hydraulic oil entering the lower fluid exchange tube 401 then enters the cavity in the left hydraulic shell 107 located on the right side of the adjacent piston plate 110, so that the total amount of hydraulic oil in the two hydraulic shells 107 remains unchanged. Through the above operation, when the wind blows and the cable shakes, no matter which side of the cable shakes due to the wind, the other side will synchronously perform the operation of Example 1, thereby enhancing the effect of cable buffering protection.

[0040] Example 4: Based on Example 3, please refer to Figure 4 and Figure 8 As shown, two rotating shells 501 symmetrically distributed on the left and right are rotatably connected in the sleeve 101 on the rear side, and a rotating shell 2 502 is rotatably connected in the rotating shell 1 501. An elastic member 6 503 is connected between the rotating shell 1 501 and the rotating shell 2 502. The elastic member 6 503 is a torsion spring. The rotating shell 1 501 is fixedly connected with a fixing ring 504. The fixing ring 504 is in one-way limiting cooperation with the adjacent locking nut 103. A rolling ball is provided at one end of the connecting tube 2 108 located in the adjacent rotating shell 2 502. An inclined groove is provided in the rotating shell 2 502. The rolling ball on the connecting tube 2 108 is located in the inclined groove in the adjacent rotating shell 2 502 and slides.

[0041] During the process of the two connecting tubes 108 moving in opposite directions, the connecting tube 108 moves and drives the adjacent rotating shell 502 to rotate. At this time, taking the connecting tube 108 on the left side as an example, when the connecting tube 108 on the left side moves to the left, the connecting tube 108 on the left side squeezes the inclined groove in the rotating shell 502 on the left side through the rolling ball at its right end, so that the rotating shell 502 on the left side rotates. At this time, since the locking nut 103 on the left side is already in a tightened state, the fixing ring 504 on the left side and the rotating shell 1 501 cannot rotate at this time. In this way, the rotating shell 502 on the left side rotates to tighten the adjacent elastic member 6 503, and the elastic member 6 503 on the left side is tightened. It starts to accumulate force until the rolling ball at the right end of the left connecting tube 108 moves to the middle of the inclined groove in the left rotating shell 502. At this time, the elastic member 6 503 accumulates force to the limit state. As the rotating shell 502 rotates, the rotating shell 502 drives the adjacent fixing ring 504 to rotate through the elastic member 6 503 and the rotating shell 1 501. At this time, the fixing ring 504 drives the locking nut 103 on the left to rotate, and further tightens the locking nut 103 on the left, thereby strengthening the fixing of the connecting tube 102 to the cable to prevent the cable from being worn and thinned and moving out of the connecting tube 102 due to the continuous and irregular shaking of the cable during the shaking of the cable.

[0042] When the left connecting tube 108 is reset to the right, the left connecting tube 108 squeezes the inclined groove in the left rotating shell 502 through the rolling ball at its right end, so that the left rotating shell 502 rotates in the opposite direction. At this time, under the action of the elastic member 503, the rotating shell 501 rotates and resets, and the rotating shell 501 drives the adjacent fixing ring 504 to rotate. However, the fixing ring 504 does not drive the left locking nut 103 to rotate, so the fixing of the cable by the connecting tube 102 will not be weakened.

[0043] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art through this disclosure that various changes or modifications may be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only intended to explain, rather than to limit, the present invention.
