[0045] See also Figure 1As shown in Figure 2, an embodiment of the present application provides a cable connection device, including a first connecting member 1, a second connecting member 2, a first connecting head 3 and a second connecting head 4, the first connecting member 1 includes a connecting rod 11 and a first connecting screw 12, the first connecting screw 12 is connected to the connecting rod 11; the second connecting member 2 includes a bending member 21 and a second connecting screw 22, the bending member 21 is connected to the second connecting screw 22; the first connecting head 3 is used to connect the cable cabinet, and the second connecting head 4 is used to connect the main cable; wherein, the first connecting screw 12 and the second connecting screw 22 are both used to connect the bypass cable, the side of the connecting rod 11 away from the first connecting screw 12 is used to connect the first connecting head 3, and the side of the bending member 21 away from the second connecting screw 22 is used to connect the second connecting head 4.

[0046] In actual applications, the first connector 1 is mainly used to connect the first connector 3, and the first connector 3 is mainly used to connect the bypass cable to the cable cabinet or the medium voltage distribution cabinet. The second connector 2 is mainly used to connect the second connector 4, and the second connector 4 is mainly used to connect the bypass cable to the main cable or the main line.

[0047] Specifically, the first connecting member 1 includes a connecting rod 11 and a first connecting screw 12, and the opposite ends of the connecting rod 11 are respectively connected to the first connecting screw 12 and the first connecting head 3. When the bypass cable needs to be connected to the medium-voltage distribution cabinet or cable box, the lead end of the bypass cable is first connected to the first connecting screw 12, and then the first connecting head 3 is used to connect the bypass cable to the medium-voltage distribution cabinet or cable cabinet; the second connecting member 2 includes a bending member 21 and a second connecting screw 22, and the opposite ends of the bending member 21 are respectively connected to the second connecting screw 22 and the second connecting head 4. When the bypass cable needs to be connected to the main line, the lead end of the bypass cable is first connected to the second connecting screw 22, and then the second connecting head 4 is connected to the main line or main cable through the insulating rod.

[0048] Compared with the prior art, the present application sets up a combined structure of a first connector 3 and a second connector 4, and the first connector 1 and the second connector 2 are respectively used to connect the bypass cable to the first connector 3 and the second connector 4, and the first connector 3 and the second connector 4 are respectively used to connect the cable cabinet or the main line, so that the device can be suitable for different application scenarios, without the need to re-purchase different connection devices, saving maintenance costs.

[0049] See also Figure 3The cable connecting device also includes a fixing member 5, a connecting rod 11 is provided with a first mounting hole 111 and a second mounting hole 112 along its axial direction, the first connecting head 3 extends into the first mounting hole 111, and the first connecting screw 12 extends into the second mounting hole 112; the connecting rod 11 is provided with at least one first fixing hole 113 and at least one second fixing hole 114 along its circumference, the first fixing hole 113 is communicated with the first mounting hole 111, and the second fixing hole 114 is communicated with the second mounting hole 112, the fixing member 5 passes through the first fixing hole 113 and abuts against the first connecting head 3, and the fixing member 5 passes through the second fixing hole 114 and abuts against the first connecting screw 12.

[0050] In practical applications, the connecting rod 11 is provided with a first mounting hole 111 and a second mounting hole 112. The first mounting hole 111 is used to mount the first connector 3, and the second mounting hole 112 is used to mount the first connecting screw 12. Specifically, the first connector 3 is inserted into the first mounting hole 111, and then the fixing member 5 is extended from the first fixing hole 113 and abuts against the first connector 3 to achieve a fixed connection between the connecting rod 11 and the first connector 3. The first connecting screw 12 is inserted into the second mounting hole 112, and then the fixing member 5 is extended from the second fixing hole 114 and abuts against the first connecting screw 12 to achieve a fixed connection between the connecting rod 11 and the first connecting screw 12. The fixing member 5 can be a bolt or a screw. In this way, the installation and disassembly of the first connector 3 and the first connecting screw 12 are more convenient, the operation is simple, and the construction is convenient.

[0051] See again Figure 3 , the first connecting screw 12 is provided with at least one groove 121 along its circumference, and the fixing member 5 is inserted into the groove 121 through the second fixing hole 114. In practical applications, in order to strengthen the fixation of the first connecting screw 12 and the connecting rod 11, the first connecting screw 12 is provided with a groove 121. When the fixing member 5 is inserted from the second fixing hole 114, the fixing member 5 can extend into the groove 121 and abut against the first connecting screw 12. The groove 121 and the fixing member 5 cooperate with each other, which can effectively limit the relative movement and relative rotation of the first connecting screw 12 and the connecting rod 11, thereby enhancing the connection stability of the first connecting screw 12 and further enhancing the connection stability of the bypass cable and the first connector 3.

[0052] See also Figure 4 The bending piece 21 has a third mounting hole 211 along its axial direction, the second connecting screw 22 extends into the third mounting hole 211, and the bending piece 21 has at least one third fixing hole 212 along its circumference, the third fixing hole 212 is connected to the third mounting hole 211, and the fixing piece 5 passes through the third fixing hole 212 and abuts against the second connecting screw 22.

[0053] In actual applications, the second connecting screw 22 and the first connecting screw 12 can adopt the same connection method. Specifically, the bending piece 21 is provided with a third mounting hole 211, and the second connecting screw 22 extends into the third mounting hole 211. The fixing piece 5 extends from the third fixing hole 212 into the third mounting hole 211 and abuts against the second connecting screw 22. The second connecting screw 22 can also be provided with a groove 121, and the fixing piece 5 extends into the third fixing hole 212 and into the groove 121, thereby increasing the connection stability between the second connecting screw 22 and the bending piece 21, thereby enhancing the connection stability between the bypass cable and the second connector 4.

[0054] See again Figure 3 The first connector 3 includes an elbow plug 31 and a wire crimping terminal 32 . The elbow plug 31 is sleeved on the outer periphery of the connecting rod 11 , and the wire crimping terminal 32 is inserted into the connecting rod 11 .

[0055] In actual applications, the elbow plug 31 is compatible with the connector in the distribution cabinet or cable box, the crimping terminal 32 is used to fix the connector in the distribution cabinet or cable box, the crimping terminal 32 extends into the first mounting hole 111 of the connecting rod 11, and the fixing part 5 is used to fix the crimping terminal 32 and the connecting rod 11. The elbow plug 31 is sleeved on the outer periphery of the connecting rod 11. The elbow plug 31 can adopt the existing models on the market, and the corresponding model is configured according to the actual installation requirements.

[0056] See also Figure 5 The second connecting head 4 includes a fixed block 41, a rotating screw rod 42 and an abutment block 43. The fixed block 41 is connected to the bending member 21. The fixed block 41 is formed with a wire fixing groove 411. The rotating screw rod 42 is threadedly connected to the fixed block 41 and is rotatably connected to the abutment block 43. The abutment block 43 can selectively approach or move away from the wire fixing groove 411.

[0057] The second connector 4 is mainly used to connect to the main line. First, the main line is inserted into the fixed line groove 411, and then the operator applies force to rotate the rotating screw rod 42. The rotating screw rod 42 drives the abutment block 43 to move toward the fixed line groove 411 until the abutment block 43 is tightly pressed against the main line of the fixed line groove 411, thereby realizing the fixed connection between the second connector 4 and the main line.

[0058] See again Figure 5 The second connector 4 includes a limit member 44 and an elastic member 45. The limit member 44 is rotatably connected to the fixed block 41. The limit member 44 is used to guide the wire (cable) into the wire fixing groove 411 and limit the wire from leaving the wire fixing groove 411. The elastic member 45 elastically abuts between the limit member 44 and the fixed block 41, so that the limit member 44 always remains in an open state in the non-working state and limits the rotation of the limit member 44.

[0059] In actual application, when the second connector 4 is not installed in the main line, the limit member 44 is rotated to the position of opening the fixing groove 411 to facilitate the main line to be placed in the fixing groove 411. After the main line is placed in the fixing groove 411, the limit member 44 is rotated to the position of closing the fixing groove 411 to limit the main line from being separated from the fixing groove 411. Then, the main line is pressed tightly by the abutment block 43 to prevent the second connector 4 from shaking on the main line. The limit member 44 can prevent the main line from falling out of the fixing groove when the abutment block 43 has not yet pressed tightly against the main line. At the same time, an elastic member 45 is arranged between the limit member 44 and the fixing block 41. The elastic member 45 can prevent the limit member 44 from rotating relative to the fixing block 41 under the action of external force, such as when the wind force is too strong, to prevent the fixing groove 411 from opening, causing the main line to be separated.

[0060] The elastic member 45 may be a torsion spring or the like.

[0061] See again Figure 4 The cable connection device includes a first insulating sleeve 6, and the first connector 1 and the second connector 2 are both sleeved with the first insulating sleeve 6. One end of the bending member 21 extends out of the first insulating sleeve 6 for connecting with the second connector 4. In practical applications, the first insulating sleeve 6 mainly serves to isolate the external circuit to prevent the internal first connector 1 and the second connector 2 from contacting with the external circuit and causing a short circuit. In addition, the first insulating sleeve 6 can also protect the internal first connector 1 and the second connector 2 to prevent the first connector 1 and the second connector 2 from being contaminated and corroded.

[0062] See also Figure 6 and Figure 7 The cable connecting device also includes a fixing clamp 7, which includes a fixing portion 71, a first clamping portion 72 and a second clamping portion 73. The first clamping portion 72 and the second clamping portion 73 are both connected to the fixing portion 71 and are arranged relatively spaced apart; a step portion 115 is provided on the outer periphery of the connecting rod 11, the fixing portion 71 is sleeved on the outer periphery of the connecting rod 11 and overlapped on the step portion 115, the first clamping portion 72, the second clamping portion 73 and the connecting rod 11 are annularly formed to form a clamping groove 74, the first connecting head 3 is inserted into the clamping groove 74, and the first clamping portion 72 and the second clamping portion 73 are fixed together by a fixing member 5 to clamp the first connecting head 3.

[0063] In one embodiment, the elbow plug 31 and the connecting rod 11 can be plugged in, and the cable connecting device can also include a fixing clamp 7, which is mainly used to fix the elbow plug 31 and the connecting rod 11. The fixing portion 71 of the fixing clamp 7 is sleeved on the outer periphery of the connecting rod 11 and overlapped on the step portion 115 to complete the installation of the fixing clamp 7; at this time, the first clamping portion 72, the second clamping portion 73 and the connecting rod 11 are arranged around to form a clamping groove 74, and the elbow plug 31 is inserted into the clamping groove 74, and then the first clamping portion 72 and the second clamping portion 73 are fixed together by the fixing member 5, and the first clamping portion 72 and the second clamping portion 73 respectively clamp the elbow plug 31 from opposite ends to fix the elbow plug 31. This method is more convenient to install and operate, and saves construction time.

[0064] See again Figure 7 The first clamping portion 72 and the second clamping portion 73 are both provided with a material reduction groove 75. The material reduction groove 75 is communicated with the clamping groove 74. The material reduction groove 75 can reduce the structural strength of the first clamping portion 72 and the second clamping portion 73 at the clamping groove 74, so that when the fixing member 5 is fixed, the first clamping portion 72 and the second clamping portion 73 are more likely to deform to clamp the clamping groove 74, thereby enhancing the clamping force on the elbow plug 31.

[0065] See also Figure 8 The cable connection device also includes a second insulating sleeve 8 and a third insulating sleeve 9. The second insulating sleeve 8 includes a first part 81 and a second part 82 connected in sequence. The first part 81 is sleeved on the outer periphery of the fixing clamp 7, and the second part 82 is sleeved on the outer periphery of the connecting rod 11; the third insulating sleeve 9 includes a third part 91 and a fourth part 92 connected in sequence. The second part 82 is inserted into the third part 91, and the fourth part is sleeved on the outer periphery of the first connecting screw 12; the third part 91 and the second part 82 are clearance-fitted or slidingly fit, and the connection between the connecting rod 11 and the first connecting screw 12 is located outside the second insulating sleeve 8 and inside the third insulating sleeve 9.

[0066] In one embodiment, the second insulating sleeve 8 is mainly used to wrap the fixing clip 7 and the connecting rod 11 to achieve insulation between the fixing clip 7 and the connecting rod 11 and the outside, the first part 81 is sleeved on the outer periphery of the fixing clip 7, and the second part 82 is sleeved on the outer periphery of the connecting rod 11 connected to the fixing clip 7; the third insulating sleeve 9 is mainly used to wrap the connecting rod 11 and the first connecting screw 12 to achieve insulation between the first connecting screw 12 and the outside, the third part 91 is sleeved on the outer periphery of the second part 82, and the fourth part 92 is sleeved on the outer periphery of the first connecting screw 12, and the third The third part 91 and the second part 82 are movably connected, for example, the third part 91 and the second part 82 are matched with a small gap, so that the operator can slide the third part 91 to disengage the third part 91 from the second part 82, and then disengage the third insulating sleeve 9, exposing the second fixing hole 114, that is, the connection part between the connecting rod 11 and the first connecting screw 12. The fixing piece 5 of the second fixing hole 114 can be removed to remove the first connecting screw 12. This arrangement greatly facilitates the removal and replacement of the bypass cable and improves the installation efficiency.

[0067] Referring to Figure 9, the bending member 21 includes a vertical portion 213, a fold line portion 214 and a connecting portion 215. The vertical portion 213 is connected to the second connecting screw 22. The fold line portion 214 is connected to the vertical portion 213, and its extension direction is set at an angle to the extension direction of the vertical portion 213. The connecting portion 215 is connected to the fold line portion 214, and the connecting portion 215 is provided with a connecting hole 2151. The connecting hole 2151 is one or more, and the multiple connecting holes 2151 are arranged in the vertical direction or in the horizontal direction.

[0068] In actual application, the fold line portion 214 of the bending member 21 is set at an angle with the vertical direction, so that the vertical portion 213 and the fold line portion 214 form an "S" shape. The fold line portion 214 is conducive to the clamping of the insulating gun. The operator holds the insulating gun and drives the bending member 21 to move, which is convenient for installing the bending member 21 at the specified position. At the same time, the bending member 21 can be connected to the second connector 4 to realize the suspension of the bypass cable on the main line. The bending member 21 may not be connected to the second connector 4, and the bending member 21 is directly connected to the busbar to realize the connection between the bypass cable and the busbar; the connection portion 215 of the bending member 21 is provided with one or more connection holes 2151, and different connection holes 2151 can be adapted according to different forms of the busbar.

[0069] Multiple connection holes 2151 can be arranged in the vertical direction or in the horizontal direction. In this way, when the second connecting head 4 is connected to the connecting part 215, the installation direction of the second connecting head 4 corresponds to the arrangement of the connection holes 2151, and the wire fixing groove 411 extends in the horizontal direction or the vertical direction. Due to the diverse arrangement of the main lines, the wire fixing grooves 411 in different directions can adapt to the main lines in different directions, thereby improving the practicability of the device.
