Description

Technical Field

[0001] The invention relates to the field of power wiring harnesses, and in particular to an anti-detachment type power wiring harness for power transmission and a use method thereof. Background Art

[0002] Electric energy transmission refers to a method of transmitting electricity from a power plant or power source from one place to another. Due to the immature technology in the early days, electric energy transmission mostly used direct current transmission, and later gradually evolved into alternating current transmission. AC transmission has many advantages, reducing the loss in power transmission and increasing the speed and transmission length. However, there is still a certain loss. I believe that when the technology matures in the future, more suitable electric energy transmission methods will appear. For example: solid-state compression of electric energy, separate collection of solar energy, etc.

[0003] The prior art has the following deficiencies:

[0004] 1. The existing power harness is usually installed manually, which is slow, has poor connection effect, low anti-drop level, and is prone to falling off after long-term use.

[0005] 2. The existing power harness is not designed with a structure to limit the position of its own insulation layer. After the harness is installed, it is easy to be twisted and displaced due to wind and other influences. Summary of the invention

[0010] The housing comprises a first housing and a second housing, which are symmetrically arranged, and the first wiring harness and the second wiring harness are arranged on the first housing and the second housing respectively;

A slot for plugging the plug-in block is arranged inside each limit block, and each clamping assembly is arranged on a limit block to lock the plug-in block. Each unlocking assembly is arranged between two clamping assemblies located at one end, and the four sleeves are symmetrically arranged at the top and bottom of the second shell, and the four positioning assemblies are symmetrically arranged at the top and bottom of the first shell;

[0012] The anti-slip mechanism is arranged inside the shell, and the anti-slip mechanism includes two hoops, two telescopic components, four arc-shaped tightening blocks and four sliding components.

[0013] Furthermore, each telescopic assembly includes a bidirectional electric push rod and two first insertion rods. The bidirectional electric push rod is fixed on the inner wall of the first shell. The two first insertion rods are respectively fixed on the two output ends of the bidirectional electric push rod. The bidirectional electric push rod is electrically connected to the controller.

[0014] Furthermore, each sliding assembly includes a rocker arm, a second plug rod, a slider and two slide rails. A cross plate is fixed on the inner wall of the first shell, and the two slide rails are fixed on the cross plate. The slider is slidably arranged between the two slide rails. The second plug rod is fixed on the outer wall of the slider, and the rocker arm is rotatably arranged on the inner wall of the first shell. Two avoidance grooves are symmetrically arranged at both ends of the rocker arm. The first plug rod and the second plug rod are respectively plugged into the two avoidance grooves, and the slider is fixedly connected to the arc-shaped clamping block through a connecting rod.

[0015] Furthermore, a plurality of anti-sliding blocks are evenly spaced on the outer wall of each arc-shaped abutting block, and each anti-sliding block is fixedly connected to the arc-shaped abutting block.

[0016] Furthermore, each positioning assembly includes a positioning block and a mounting block. The mounting block is fixed on the outer wall of the first shell, the positioning block is fixed on the outer wall of the mounting block, and a positioning groove for the positioning block to be inserted is provided inside the sleeve.

[0017] Furthermore, each clamping assembly includes a wedge-shaped buckle, a clamping spring and a sliding rod. A sliding groove is provided inside the limit block. The wedge-shaped buckle is slidably arranged inside the sliding groove. The sliding rod is fixed at one end of the wedge-shaped buckle. The sliding rod is slidably connected to the limit block. The clamping spring is sleeved on the outer wall of the sliding rod. The outer wall of the wedge-shaped buckle and the inner wall of the sliding groove respectively abut against the two ends of the clamping spring. A wedge-shaped groove for the wedge-shaped buckle to be clamped is provided on the outer wall of the end of the insertion block away from the first shell.

[0018] Furthermore, one end of each plug block away from the first shell is integrally formed and has an oblique angle.

[0019] Furthermore, each unlocking assembly includes a pull plate and two guide rods, the two guide rods are fixed on the second shell, the pull plate is fixed between the ends of the two sliding rods away from the wedge-shaped buckle, and the two guide rods are slidably connected to the pull plate.

[0020] Furthermore, a plurality of heat dissipation holes are provided at the bottom of the first shell and the bottom of the second shell.

[0021] A method for using an anti-detachment type power harness for power transmission comprises the following steps:

[0022] S1: Docking of the first wiring harness and the second wiring harness:

[0023] The plug port and the socket port facilitate that when the first housing and the second housing are successfully docked, the first wiring harness and the second wiring harness are successfully docked, so as to realize the electrical connection between the two, thereby realizing the power transmission effect of the two transmission towers;

[0024] When it is necessary to install a power harness between two transmission towers, that is, when the first harness and the second harness need to be docked, the worker aligns the first shell with the second shell, and at this time ensures that the positioning block is aligned with the positioning groove in the sleeve, and then pushes the installation block, and pushes the positioning block to the slot in the sleeve until the positioning block is plugged into the positioning groove in the sleeve block. At this time, the plug-in port and the socket port are successfully docked synchronously, and the docking of the first harness and the second harness is realized. The positioning component is designed to improve the accuracy of the docking of the first shell and the second shell, thereby ensuring that the first harness and the second harness can be accurately docked, improving the accuracy of the docking, and then helping to improve the installation efficiency of the power harness.

[0025] When the first shell and the second shell are docked, that is, when the first wiring harness and the second wiring harness are docked, the plug block is also synchronously inserted into the slot inside the limit block. When the plug block is inserted into the slot until it contacts the beveled edge of the wedge buckle, the wedge buckle is slidably connected to the limit block through the sliding rod, and the wedge buckle is slidably connected to the slide groove, so that the wedge buckle is contracted inside the slide groove. At this time, the clamping spring changes from the initial state to the contracted state, and when the plug block is inserted into place, that is, when the wedge buckle is aligned with the wedge slot on the plug block, the plug block no longer resists the wedge buckle, so that under the resetting action of the clamping spring, the wedge buckle is automatically inserted into the inside of the wedge slot, so that the wedge buckle locks the plug block. Since one end of the wedge buckle is a beveled edge and the other end is a straight edge, when it is inserted into the wedge slot, it can completely prevent the plug block from detaching from the limit block. It must be unlocked by the unlocking component, thereby preventing the first shell and the second shell from detaching, that is, effectively preventing the first wiring harness and the second wiring harness from detaching, achieving a three-layer anti-detachment effect.

[0026] The bevel angle is designed to increase the speed of the plug-in block when it is inserted into the slot and to contact the beveled edge of the wedge-shaped buckle, so that the wedge-shaped buckle can be easily pushed into the inside of the slide slot, thereby increasing the clamping speed, which in turn helps to improve the locking efficiency, increase the connection speed between the first shell and the second shell, that is, improve the docking efficiency of the first wiring harness and the second wiring harness, and further improve the installation efficiency of the power harness.

[0027] S2: Anti-detachment treatment of the first and second harnesses:

[0028] The two hoops are respectively connected with the first wiring harness and the second wiring harness by interference fit, thus playing a role of preventing the wires from falling off.

[0029] When the first wiring harness and the second wiring harness are successfully docked, the bidirectional electric push rod is started through the controller, so that its two output ends are extended, that is, the two output ends are away from each other. Since the output ends of the bidirectional electric push rod are fixedly connected to the two first plug rods respectively, the two first plug rods are driven to move away from each other.

[0030] Since the swing rod is rotatably connected to the inner wall of the second shell, two avoidance grooves are symmetrically designed at both ends of the swing rod, the second plug rod is fixedly connected to the slider, the slider is slidably connected to the two slide rails, and the first plug rod and the second plug rod are respectively plugged into the two avoidance grooves. Therefore, when the two first plug rods move away from each other, the first plug rod will contact the avoidance groove at the left end of the swing rod, thereby causing the swing rod to rotate toward the end close to the first wiring harness, and pushing the slider toward the end close to the first wiring harness. Since the slider is fixedly connected to the arc-shaped clamping block through the connecting rod, it drives the arc-shaped clamping block to clamp the outer wall of the first wiring harness, and cooperates with another sliding component to achieve clamping of the two ends of the first wiring harness, so that the first wiring harness and the second wiring harness are clamped and limited again after docking, thereby achieving a two-layer anti-slip effect.

[0031] A plurality of anti-sliding blocks can increase the friction between the arc-shaped clamping block and the first wiring harness, thereby increasing the clamping effect, which is beneficial to improving the anti-slip effect.

[0032] S3: Troubleshooting of electrical components inside the housing:

[0033] When an electrical component inside the shell fails, the pull plate is manually pulled toward the end away from the shell, thereby driving the two slide bars to slide inside the slide groove toward the end away from the plug block, that is, driving the two wedge-shaped clips to disengage from the two wedge-shaped slots, thereby unlocking the plug block with the limit block, making it convenient to open the first shell and the second shell for fault detection.

[0034] S4: Heat dissipation of power harness:

[0035] Since the power harness generates high temperature when working, if the heat accumulates inside the shell for a long time, the internal temperature will continue to rise, which may easily cause the insulation layer of the power harness to break down, causing short circuit tripping, or even fire, resulting in heavy losses. Therefore, several heat dissipation holes are designed to discharge the generated heat in time to avoid heavy losses and improve the safety performance of the power harness operation.

[0036] Beneficial effects of the present invention:

[0037] 1. The present invention adopts a quick-joined structure by designing a controller, a housing, a plug-in mechanism and an anti-drop-off mechanism. Manual installation is not required. The installation of the power harness can be achieved through the cooperation of the plug-in mechanism and the anti-drop-off mechanism, thereby improving the installation speed and connection effect and avoiding the risk of falling off during long-term use.

[0038] 2. The present invention can achieve a three-layer anti-detachment effect for the power wiring harness by designing two ferrules, a plug-in mechanism and an anti-detachment mechanism. Compared with the existing single-layer anti-detachment structure, the anti-detachment level of the power wiring harness is greatly improved. At the same time, it is not easy to twist or shift when affected by wind, etc., thereby ensuring power transmission.

[0039] 3. The present invention designs the shell into a combined structure of a first shell and a second shell, and designs an unlocking component, which not only facilitates the docking of the power harness, that is, the installation effect, but also enables the first shell and the second shell to be quickly disassembled and fault detection to be performed through the unlocking component when a fault occurs in the power component inside the shell, thereby improving the maintenance efficiency of the wiring harness, which is beneficial to increasing the service life of the wiring harness and reducing the overall cost of power transmission.

[0040] 4. The present invention designs a plurality of heat dissipation holes at the bottom of the first shell and the second shell. Since the power harness generates high temperature when working, if the heat is accumulated inside the shell, the internal temperature will continue to rise, which may easily lead to the breakdown of the insulation layer of the power harness, causing short circuit tripping, and even fire, resulting in heavy losses. Therefore, a plurality of heat dissipation holes are designed to discharge the generated heat in time to avoid heavy losses and improve the safety performance of the operation of the power harness.

[0041] 5. The present invention can improve the docking accuracy of the first shell and the second shell by designing a positioning component, thereby ensuring that the first wiring harness and the second wiring harness can be accurately docked, improving the docking accuracy, and further facilitating improving the installation efficiency of the power harness.

DETAILED DESCRIPTION

[0052] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0053] Among them, the drawings are only used for illustrative purposes and represent only schematic diagrams rather than actual pictures, and should not be understood as limitations on this patent; in order to better illustrate the embodiments of the present invention, some parts of the drawings will be omitted, enlarged or reduced, and do not represent the size of the actual product.

[0054] Reference Figures 1 to 8 As shown in the figure, the present invention provides an anti-detachment type power harness for power transmission, including a first harness 1 and a second harness 2, wherein adjacent ends of the first harness 1 and the second harness 2 are respectively fixed with a plug port 3 and a socket port 4, wherein the plug port 3 and the socket port 4 facilitate successful docking of the first housing 6 and the second housing 7, thereby achieving electrical connection between the first harness 1 and the second harness 2, and thus achieving power transmission effect of two transmission towers;

[0055] It also includes a controller, a housing 5, a plug-in mechanism and an anti-drop mechanism;

[0056] The housing 5 includes a first housing 6 and a second housing 7, which are symmetrically arranged, and the first wiring harness 1 and the second wiring harness 2 are arranged on the first housing 6 and the second housing 7 respectively;

[0057] The plug-in mechanism is arranged between the first shell 6 and the second shell 7, and the plug-in mechanism includes four plug-in blocks 8, four limit blocks 9, four sleeves 10, four clamping components 11, four positioning components 12 and two unlocking components 13. The four plug-in blocks 8 are symmetrically arranged on the outer walls at both ends of the first shell 6, and the four limit blocks 9 are symmetrically arranged on the outer walls at both ends of the second shell 7. A slot for plugging the plug-in block 8 is provided inside each limit block 9, and each clamping component 11 is arranged on a limit block 9 to lock the plug-in block 8. Each unlocking component 13 is arranged between two clamping components 11 located at one end, and the four sleeves 10 are symmetrically arranged at the top and bottom of the second shell 7. The four positioning components 12 are symmetrically arranged at the top and bottom of the first shell 6;

[0058] The anti-slip mechanism is arranged inside the shell 5, and the anti-slip mechanism includes two hoops 14, two telescopic components 15, four arc-shaped tightening blocks 16 and four sliding components 17. The two hoops 14 are respectively fixed on the outer walls of the first shell 6 and the second shell 7, and the two hoops 14 are respectively interference-connected with the first wiring harness 1 and the second wiring harness 2, which play an anti-slip effect. The two telescopic components 15 are respectively arranged inside the first shell 6 and the second shell 7, and the four sliding components 17 are symmetrically arranged inside the first shell 6 and the second shell 7. Each arc-shaped tightening block 16 is fixed on a sliding component 17, and each telescopic component 15 is electrically connected to the controller.

[0059] Reference Figures 1 to 8 As shown, each telescopic assembly 15 includes a bidirectional electric push rod 18 and two first plug rods 19. The bidirectional electric push rod 18 is fixed on the inner wall of the first shell 6. The two first plug rods 19 are respectively fixed on the two output ends of the bidirectional electric push rod 18. The bidirectional electric push rod 18 is electrically connected to the controller. When the first wiring harness 1 and the second wiring harness 2 are successfully docked, the bidirectional electric push rod 18 is started by the controller, so that its two output ends are extended, that is, the two output ends are away from each other. Since the output ends of the bidirectional electric push rod 18 are respectively fixedly connected to the two first plug rods 19, the two first plug rods 19 are driven to move away from each other.

[0060] Reference Figures 1 to 8 As shown, each sliding assembly 17 includes a swing rod 20, a second plug rod 21, a slider 22 and two slide rails 23. A transverse plate is fixed on the inner wall of the first shell 6, and the two slide rails 23 are fixed on the transverse plate. The slider 22 is slidably arranged between the two slide rails 23. The second plug rod 21 is fixed on the outer wall of the slider 22. The swing rod 20 is rotatably arranged on the inner wall of the first shell 6. Two avoidance grooves are symmetrically arranged at both ends of the swing rod 20. The first plug rod 19 and the second plug rod 21 are respectively plugged into the two avoidance grooves. The slider 22 is fixedly connected to the arc-shaped abutting block 16 through a connecting rod 24. Since the swing rod 20 is rotatably connected to the inner wall of the second shell 7, the two ends of the swing rod 20 are symmetrically designed with two avoidance grooves. 21 is fixedly connected to the slider 22, the slider 22 is slidably connected to the two slide rails 23, and the first plug rod and the second plug rod 21 are respectively plugged into the two avoidance grooves. Therefore, when the two first plug rods 19 move away from each other, the first plug rod 19 will contact the avoidance groove at the left end of the swing rod 20, so that the swing rod 20 rotates toward the end close to the first wiring harness 1, and pushes the slider 22 toward the end close to the first wiring harness 1. Since the slider 22 is fixedly connected to the arc-shaped clamping block 16 through the connecting rod 24, the arc-shaped clamping block 16 is driven to clamp the outer wall of the first wiring harness 1, and cooperate with another sliding component 17 to achieve the clamping of the two ends of the first wiring harness 1, so that the first wiring harness 1 and the second wiring harness 2 are clamped and limited again after docking, which has a two-layer anti-slip effect.

[0061] Reference Figures 1 to 8 As shown, a plurality of anti-sliding blocks 25 are evenly spaced on the outer wall of each arc-shaped clamping block 16, and each anti-sliding block 25 is fixedly connected to the arc-shaped clamping block 16. The plurality of anti-sliding blocks 25 can increase the friction between the arc-shaped clamping block 16 and the first wiring harness 1, thereby increasing the clamping effect, which is beneficial to improving the anti-slip effect.

[0062] Reference Figures 1 to 8 As shown, each positioning assembly 12 includes a positioning block 26 and a mounting block 27. The mounting block 27 is fixed on the outer wall of the first shell 6. The positioning block 26 is fixed on the outer wall of the mounting block 27. The interior of the sleeve 10 is provided with a positioning groove for the positioning block 26 to be plugged in. When it is necessary to install the power harness between the two transmission towers, that is, when it is necessary to dock the first harness 1 and the second harness 2, the worker aligns the first shell 6 with the second shell 7. At this time, ensure that the positioning block 26 is aligned with the positioning groove in the sleeve 10, and then push the mounting block 27 to push the positioning block 26 to the slot in the sleeve 10 until the positioning block 26 is plugged into the positioning groove in the sleeve block. At this time, the plug-in port 3 and the socket port 4 are successfully docked synchronously, and the docking of the first harness 1 and the second harness 2 is realized. The positioning assembly 12 is designed to improve the docking accuracy of the first shell 6 and the second shell 7, thereby ensuring that the first harness 1 and the second harness 2 can be accurately docked, improving the docking accuracy, and thus helping to improve the installation efficiency of the power harness.

[0063] Reference Figures 1 to 8As shown, each clamping assembly 11 includes a wedge-shaped buckle 28, a tightening spring 29 and a sliding rod 30. A sliding groove is provided inside the limit block 9, and the wedge buckle 28 is slidably arranged inside the sliding groove. The sliding rod 30 is fixedly arranged at one end of the wedge buckle 28, and the sliding rod 30 is slidably connected with the limit block 9. The tightening spring 29 is sleeved on the outer wall of the sliding rod 30, and the outer wall of the wedge buckle 28 and the inner wall of the sliding groove respectively abut against the two ends of the tightening spring 29. A wedge-shaped clamping groove for the wedge buckle 28 to be engaged is provided on the outer wall of the end of the plug-in block 8 away from the first shell 6. When the first shell 6 is docked with the second shell 7, that is, when the first wiring harness 1 and the second wiring harness 2 are docked, the plug-in block 8 is also synchronously inserted into the slot inside the limit block 9. When the plug-in block 8 is inserted into the slot until it contacts the hypotenuse of the wedge buckle 28, the wedge buckle 28 is connected to the limit block 9 through the sliding rod 30. The block 9 is slidably connected, and the wedge-shaped buckle 28 is slidably connected to the slide groove, so that the wedge-shaped buckle 28 is contracted inside the slide groove. At this time, the clamping spring 29 changes from the initial state to the contracted state, and when the plug block 8 is inserted into place, that is, when the wedge buckle 28 is aligned with the wedge-shaped slot on the plug block 8, the plug block 8 no longer resists the wedge buckle 28, so that under the resetting action of the clamping spring 29, the wedge buckle 28 is automatically inserted into the inside of the wedge slot, thereby locking the plug block 8 with the wedge buckle 28. Since one end of the wedge buckle 28 is a bevel and the other end is a straight edge, when it is inserted into the wedge slot, it can completely prevent the plug block 8 from detaching from the limit block 9, and it must be unlocked by the unlocking component 13, thereby preventing the first shell 6 and the second shell 7 from detaching, that is, effectively preventing the first wiring harness 1 and the second wiring harness 2 from detaching, achieving a three-layer anti-detachment effect.

[0064] Reference Figures 1 to 8 As shown, the end of each plug block 8 away from the first shell 6 is integrally formed with a bevel 31. The bevel 31 is to improve the plug block 8 when it is inserted into the slot and to contact the beveled edge of the wedge-shaped buckle 28, so that the wedge-shaped buckle 28 can be easily pushed into the inside of the slide groove, thereby improving the clamping speed, which is beneficial to improving the locking efficiency, increasing the connection speed between the first shell 6 and the second shell 7, that is, improving the docking efficiency of the first wire harness 1 and the second wire harness 2, and further improving the installation efficiency of the power harness.

[0065] Reference Figures 1 to 8 As shown, each unlocking assembly 13 includes a pull plate 32 and two guide rods 33. The two guide rods 33 are fixed on the second shell 7. The pull plate 32 is fixed between the ends of the two slide bars 30 away from the wedge-shaped buckles 28. The two guide rods 33 are slidably connected to the pull plate 32. When a fault occurs in the electrical component inside the shell 5, the pull plate 32 is manually pulled toward the end away from the shell 5, thereby driving the two slide bars 30 to slide inside the slide groove toward the end away from the plug block 8, that is, driving the two wedge-shaped buckles 28 to disengage from the two wedge-shaped grooves, thereby realizing the unlocking of the plug block 8 by the limit block 9, and facilitating the insertion of the first shell 6 and the second shell 7 for fault detection.

[0066] Reference Figures 1 to 8 As shown, the bottom of the first shell 6 and the bottom of the second shell 7 are each provided with a plurality of heat dissipation holes 34. Since the power harness generates high temperature when working, if it is constantly accumulated inside the shell 5, the internal temperature will continue to rise, which may easily lead to the breakdown of the insulation layer of the power harness, causing short circuit tripping, or even fire, resulting in significant losses. Therefore, a plurality of heat dissipation holes 34 are designed to discharge the generated heat in time to avoid significant losses and improve the safety performance of the operation of the power harness.

[0067] A method for using an anti-detachment type power harness for power transmission comprises the following steps:

[0068] S1: Docking of the first wiring harness and the second wiring harness:

[0069] The plug port 3 and the socket port 4 facilitate that when the first housing 6 and the second housing 7 are successfully docked, the first wiring harness 1 and the second wiring harness 2 are successfully docked, and the electrical connection between the two is realized, thereby realizing the power transmission effect of the two transmission towers;

[0070] When it is necessary to install a power harness between two transmission towers, that is, when it is necessary to connect the first harness 1 and the second harness 2, the worker aligns the first shell 6 with the second shell 7, and at this time ensures that the positioning block 26 is aligned with the positioning groove in the sleeve 10, and then pushes the installation block 27 to push the positioning block 26 to the slot in the sleeve 10 until the positioning block 26 is plugged into the positioning groove in the sleeve block. At this time, the plug-in port 3 and the socket port 4 are successfully connected synchronously, and the connection between the first harness 1 and the second harness 2 is realized. The positioning component 12 is designed to improve the accuracy of the connection between the first shell 6 and the second shell 7, so as to ensure that the first harness 1 and the second harness 2 can be accurately connected, improve the connection accuracy, and thus help improve the installation efficiency of the power harness.

[0071] When the first housing 6 and the second housing 7 are docked, that is, when the first wiring harness 1 and the second wiring harness 2 are docked, the plug block 8 is also synchronously inserted into the slot inside the limit block 9. When the plug block 8 is inserted into the slot until it contacts the bevel of the wedge buckle 28, the wedge buckle 28 is slidably connected to the limit block 9 through the slide bar 30, and the wedge buckle 28 is slidably connected to the slide groove, so that the wedge buckle 28 is contracted inside the slide groove. At this time, the pressing spring 29 changes from the initial state to the contracted state, and when the plug block 8 is inserted into place, that is, when the wedge buckle 28 is in contact with the plug block 8, the wedge buckle 28 is in contact with the bevel of the wedge buckle 28. When the wedge-shaped slots are aligned, the plug block 8 no longer conflicts with the wedge-shaped buckle 28, so that the wedge-shaped buckle 28 is automatically inserted into the inside of the wedge-shaped slot under the resetting action of the clamping spring 29, thereby locking the plug block 8 with the wedge buckle 28. Since one end of the wedge buckle 28 is a bevel and the other end is a straight edge, when it is inserted into the wedge slot, it can completely prevent the plug block 8 from detaching from the limit block 9, and it must be unlocked by the unlocking component 13, thereby preventing the first shell 6 and the second shell 7 from detaching, that is, effectively preventing the first wiring harness 1 and the second wiring harness 2 from detaching, achieving a three-layer anti-detachment effect.

[0072] The bevel 31 is designed to increase the speed of the plug 8 when it is inserted into the slot and to contact the beveled edge of the wedge-shaped buckle 28, so that the wedge-shaped buckle 28 can be easily pushed into the inside of the slide slot, thereby increasing the clamping speed, which is beneficial to improving the locking efficiency, increasing the connection speed between the first shell 6 and the second shell 7, that is, improving the docking efficiency of the first wire harness 1 and the second wire harness 2, and further improving the installation efficiency of the power harness.

[0073] S2: Anti-detachment treatment of the first and second harnesses:

[0074] The two hoops 14 are respectively connected with the first wire harness 1 and the second wire harness 2 by interference fit, thus playing a role of preventing the wire harness from falling off.

[0075] When the first wiring harness 1 and the second wiring harness 2 are successfully docked, the bidirectional electric push rod 18 is started by the controller, so that its two output ends are extended, that is, the two output ends are away from each other. Since the output ends of the bidirectional electric push rod 18 are fixedly connected to the two first plug rods 19 respectively, the two first plug rods 19 are driven to move away from each other.

[0076] Since the swing rod 20 is rotatably connected to the inner wall of the second shell 7, the two ends of the swing rod 20 are symmetrically designed with two avoidance grooves, the second plug rod 21 is fixedly connected to the slider 22, and the slider 22 is slidably connected to the two slide rails 23. The first plug rod and the second plug rod 21 are respectively plugged into the two avoidance grooves. Therefore, when the two first plug rods 19 move away from each other, the first plug rod 19 will contact the avoidance groove at the left end of the swing rod 20, so that the swing rod 20 rotates toward the end close to the first wiring harness 1, and the slider 22 is pushed toward the end close to the first wiring harness 1. Since the slider 22 is fixedly connected to the arc-shaped clamping block 16 through the connecting rod 24, it drives the arc-shaped clamping block 16 to clamp the outer wall of the first wiring harness 1, and cooperates with another sliding component 17 to achieve the clamping of the two ends of the first wiring harness 1, so that the first wiring harness 1 and the second wiring harness 2 are clamped and limited again after docking, which has a two-layer anti-slip effect.

[0077] A plurality of anti-sliding blocks 25 can increase the friction between the arc-shaped pressing block 16 and the first wiring harness 1, thereby increasing the pressing effect, which is beneficial to improving the anti-slip effect.

[0078] S3: Troubleshooting of electrical components inside the housing:

[0079] When an electrical component inside the housing 5 fails, the pull plate 32 is manually pulled toward the end away from the housing 5, thereby driving the two slide bars 30 to slide inside the slide groove toward the end away from the plug block 8, that is, driving the two wedge-shaped buckles 28 to disengage from the two wedge-shaped slots, thereby unlocking the plug block 8 by the limit block 9, making it convenient to open the first shell 6 and the second shell 7 for fault detection.

[0080] S4: Heat dissipation of power harness:

[0081] Since the power harness generates high temperature when working, if the heat is accumulated inside the shell 5, the internal temperature will continue to rise, which may easily cause the insulation layer of the power harness to break down, causing short circuit tripping, or even fire, resulting in heavy losses. Therefore, a plurality of heat dissipation holes 34 are designed to discharge the generated heat in time to avoid heavy losses and improve the safety performance of the operation of the power harness.

[0082] The working principle of the present invention is as follows: when the plug-in port 3 and the socket port 4 facilitate the successful docking of the first shell 6 and the second shell 7, the first wiring harness 1 and the second wiring harness 2 are successfully docked, and the electrical connection between the two is realized, thereby realizing the power transmission effect of the two transmission towers. When it is necessary to install the power harness between the two transmission towers, that is, when the first wiring harness 1 and the second wiring harness 2 need to be docked, the worker aligns the first shell 6 with the second shell 7, and at this time ensures that the positioning block 26 is aligned with the positioning groove in the sleeve 10, and then pushes the installation block 27 to push the positioning block 26 to the slot in the sleeve 10 until the positioning block 26 is plugged into the positioning groove in the sleeve block. At this time, the plug-in port 3 and the socket port 4 are successfully docked synchronously, and the docking of the first wiring harness 1 and the second wiring harness 2 is realized. The positioning component 12 is designed to improve the docking accuracy of the first shell 6 and the second shell 7, thereby ensuring that the first wiring harness 1 and the second wiring harness 2 can be accurately docked, improving the docking accuracy, and thus helping to improve the installation efficiency of the power harness.

[0083] When the first shell 6 is docked with the second shell 7, that is, when the first wiring harness 1 and the second wiring harness 2 are docked, the plug block 8 is also synchronously inserted into the slot inside the limit block 9. When the plug block 8 is inserted into the slot until it contacts the bevel of the wedge-shaped buckle 28, the wedge-shaped buckle 28 is slidably connected to the limit block 9 through the slide rod 30, and the wedge-shaped buckle 28 is slidably connected to the slide groove, so that the wedge-shaped buckle 28 contracts inside the slide groove. At this time, the clamping spring 29 changes from the initial state to the contracted state, and when the plug block 8 is inserted into place, that is, when the wedge-shaped buckle 28 is aligned with the wedge-shaped slot on the plug block 8, the plug block 8 no longer contacts the wedge-shaped buckle 28, so that the wedge-shaped buckle 28 is automatically clamped into the inside of the wedge-shaped slot under the resetting action of the clamping spring 29, realizing the wedge-shaped buckle. 28 locks the plug block 8. Since one end of the wedge-shaped buckle 28 is a bevel and the other end is a straight edge, when it is inserted into the wedge-shaped slot, it can completely prevent the plug block 8 from detaching from the limit block 9. It must be unlocked by the unlocking component 13, thereby preventing the first shell 6 and the second shell 7 from detaching, that is, effectively preventing the first wiring harness 1 and the second wiring harness 2 from detaching, and achieving a three-layer anti-detachment effect. The bevel 31 is to increase the bevel edge of the wedge-shaped buckle 28 when the plug block 8 is inserted into the slot, that is, the wedge-shaped buckle 28 can be easily pushed into the inside of the slide groove, thereby increasing the clamping speed, which is beneficial to improving the locking efficiency, increasing the connection speed of the first shell 6 and the second shell 7, that is, improving the docking efficiency of the first wiring harness 1 and the second wiring harness 2, and further improving the installation efficiency of the power wiring harness.

[0084] The two hoops 14 are respectively connected with the first wiring harness 1 and the second wiring harness 2 by interference fit, which plays a role of preventing the first wiring harness 1 and the second wiring harness 2 from falling off. When the first wiring harness 1 and the second wiring harness 2 are successfully connected, the two-way electric push rod 18 is started by the controller, so that the two output ends thereof are extended, that is, the two output ends are away from each other. Since the output ends of the two-way electric push rod 18 are respectively fixedly connected with the two first plug rods 19, the two first plug rods 19 are driven to move away from each other. Since the swing rod 20 is rotatably connected with the inner wall of the second shell 7, the two ends of the swing rod 20 are symmetrically designed with two avoidance grooves, the second plug rod 21 is fixedly connected with the slider 22, the slider 22 is slidably connected with the two slide rails 23, and the first plug rod and the second plug rod 21 are respectively plugged into the two avoidance grooves. When the two first plug rods 19 move away from each other, the first plug rod 19 will contact the avoidance groove at the left end of the swing rod 20, so that the swing rod 20 rotates toward the end close to the first wiring harness 1, and pushes the slider 22 toward the end close to the first wiring harness 1. Since the slider 22 is fixedly connected to the arc-shaped clamping block 16 through the connecting rod 24, the arc-shaped clamping block 16 is driven to clamp the outer wall of the first wiring harness 1, and cooperate with another sliding component 17 to achieve clamping of the two ends of the first wiring harness 1, so that the first wiring harness 1 and the second wiring harness 2 are clamped and limited again after docking, which plays a double-layer anti-slip effect. Several anti-sliding blocks 25 can increase the friction between the arc-shaped clamping block 16 and the first wiring harness 1, thereby increasing the clamping effect, which is beneficial to improving the anti-slip effect.

[0085] When an electrical component inside the housing 5 fails, the pull plate 32 is manually pulled toward the end away from the housing 5, thereby driving the two slide bars 30 to slide inside the slide groove toward the end away from the plug block 8, that is, driving the two wedge-shaped buckles 28 to disengage from the two wedge-shaped slots, thereby unlocking the plug block 8 by the limit block 9, making it convenient to open the first shell 6 and the second shell 7 for fault detection.

[0086] Since the power harness generates high temperature when working, if the heat is accumulated inside the shell 5, the internal temperature will continue to rise, which may easily cause the insulation layer of the power harness to break down, causing short circuit tripping, or even fire, resulting in heavy losses. Therefore, a plurality of heat dissipation holes 34 are designed to discharge the generated heat in time to avoid heavy losses and improve the safety performance of the operation of the power harness.

10. A method for using an anti-dropping power harness for power transmission, comprising the following steps: S1: Docking of the first wiring harness and the second wiring harness: The plug port (3) and the socket port (4) facilitate that when the first housing (6) and the second housing (7) are successfully docked, the first wiring harness (1) and the second wiring harness (2) are successfully docked, achieving electrical connection between the two, thereby achieving the power transmission effect of the two transmission towers; When it is necessary to install a power harness between two transmission towers, that is, when it is necessary to dock the first harness (1) and the second harness (2), the worker aligns the first shell (6) with the second shell (7), and ensures that the positioning block (26) is aligned with the positioning groove in the sleeve (10), and then pushes the installation block (27) to push the positioning block (26) into the slot in the sleeve (10) until the positioning block (26) is plugged into the positioning groove in the sleeve block. At this time, the plug-in port (3) and the socket port (4) are successfully docked synchronously, and the docking of the first harness (1) and the second harness (2) is achieved. The positioning component (12) is designed to improve the docking accuracy of the first shell (6) and the second shell (7), thereby ensuring that the first harness (1) and the second harness (2) can be accurately docked, improving the docking accuracy, and thus facilitating the improvement of the installation efficiency of the power harness. When the first housing (6) and the second housing (7) are docked, that is, when the first wiring harness (1) and the second wiring harness (2) are docked, the plug block (8) is also synchronously inserted into the slot inside the limit block (9). When the plug block (8) is inserted into the slot until it contacts the oblique edge of the wedge-shaped buckle (28), the wedge-shaped buckle (28) is slidably connected to the limit block (9) through the slide bar (30), and the wedge-shaped buckle (28) is slidably connected to the slide groove, so that the wedge-shaped buckle (28) is contracted inside the slide groove. At this time, the pressing spring (29) changes from the initial state to the contracted state, and when the plug block (8) is inserted into place, that is, when the wedge-shaped buckle (28) and the plug block (8) are in contact with each other, the wedge-shaped buckle (28) is in contact with the oblique edge of the wedge-shaped buckle (28). ), the insert block (8) no longer contacts the wedge-shaped buckle (28), so that the wedge-shaped buckle (28) is automatically inserted into the wedge-shaped buckle (28) under the reset action of the pressing spring (29), thereby locking the insert block (8) with the wedge-shaped buckle (28). Since one end of the wedge-shaped buckle (28) is a bevel and the other end is a straight edge, when it is inserted into the wedge-shaped buckle (28), it can completely prevent the insert block (8) from being separated from the limit block (9). It must be unlocked by the unlocking component (13), thereby preventing the first shell (6) and the second shell (7) from being separated, that is, effectively preventing the first wire harness (1) and the second wire harness (2) from being separated, achieving a three-layer anti-separation effect. The bevel (31) is to increase the speed of the plug (8) when it is inserted into the slot and to contact the bevel of the wedge-shaped buckle (28), so that the wedge-shaped buckle (28) can be easily pushed into the inside of the slide slot, thereby increasing the clamping speed, which is beneficial to improving the locking efficiency, increasing the connection speed of the first shell (6) and the second shell (7), that is, improving the docking efficiency of the first wire harness (1) and the second wire harness (2), and further improving the installation efficiency of the power wire harness. S2: Anti-detachment treatment of the first and second harnesses: The two hoops (14) are respectively connected to the first wire harness (1) and the second wire harness (2) in an interference fit manner, thereby achieving an anti-slip effect; When the first wiring harness (1) and the second wiring harness (2) are successfully docked, the controller starts the bidirectional electric push rod (18), so that both output ends thereof are extended, that is, the two output ends are moved away from each other. Since the output ends of the bidirectional electric push rod (18) are respectively fixedly connected to the two first plug rods (19), the two first plug rods (19) are driven to move away from each other. Since the swing rod (20) is rotatably connected to the inner wall of the second housing (7), two avoidance grooves are symmetrically designed at both ends of the swing rod (20), the second plug rod (21) is fixedly connected to the slider (22), the slider (22) is slidably connected to the two slide rails (23), and the first plug rod and the second plug rod (21) are respectively plugged into the two avoidance grooves, so that when the two first plug rods (19) move away from each other, the first plug rod (19) will contact the avoidance groove at the left end of the swing rod (20), so that the swing rod (20) moves to The end close to the first wiring harness (1) is rotated to push the slider (22) toward the end close to the first wiring harness (1). Since the slider (22) is fixedly connected to the arc-shaped clamping block (16) via the connecting rod (24), the arc-shaped clamping block (16) is driven to clamp against the outer wall of the first wiring harness (1). In cooperation with another sliding component (17), the two ends of the first wiring harness (1) are clamped, so that the first wiring harness (1) and the second wiring harness (2) are clamped and limited again after docking, achieving a double-layer anti-slip effect. A plurality of anti-sliding blocks (25) can increase the friction between the arc-shaped pressing block (16) and the first wire harness (1), thereby increasing the pressing effect and facilitating the improvement of the anti-slip effect. S3: Troubleshooting of electrical components inside the housing: When an electrical component inside the housing (5) fails, the pull plate (32) is manually pulled toward the end away from the housing (5), thereby driving the two slide bars (30) to slide inside the slide groove toward the end away from the plug block (8), that is, driving the two wedge-shaped buckles (28) to disengage from the two wedge-shaped slots, thereby unlocking the plug block (8) by the limit block (9), making it convenient to open the first housing (6) and the second housing (7) for fault detection. S4: Heat dissipation of power harness: Since the power harness generates high temperature when working, if the heat is accumulated inside the housing (5), the internal temperature will continue to rise, which may easily lead to the breakdown of the insulation layer of the power harness, causing short circuit tripping, or even fire, resulting in significant losses. Therefore, a plurality of heat dissipation holes (34) are designed to discharge the generated heat in time, avoid significant losses, and improve the safety performance of the power harness operation.
