[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. The wiring assembly and the wire stripping assembly are provided. By pressing down the movable cutting plate, the movable cutting plate and the fixed cutting plate are used in cooperation to realize the cutting process of the flexible cable sheath or the outer skin of the inner core body. Then, by pulling up the movable cutting plate, the movable clamping plate is driven to move downward. The flexible cable sheath or the outer skin of the inner core body can be fixed by pressing and clamping through the movable clamping plate and the fixed clamping plate, thereby realizing the adjustment of the length of the flexible cable. When the cable connector plug is damaged, only the wiring assembly needs to be replaced. When the end of the flexible cable is damaged or the length of the flexible cable needs to be adjusted, the redundant outer skin and sheath can be removed through the wire stripping assembly, so that the flexible cable can be reconnected to the wiring assembly, effectively reducing the use cost of the flexible cable. In addition, users do not need to carry additional cutting tools, improving the convenience of reusing the flexible cable and the connecting device, and making the use more flexible;

[0026] 2. The heat dissipation assembly is provided. The heat at the connection is led out through the temperature conduction strip, the condensate and the temperature conduction block, and then the contact area with the air is increased through the trapezoidal heat conduction plate, the installation folding edge and the conduction folding edge to improve the heat dissipation effect, effectively avoiding the situation of fire caused by excessive heat at the circuit connection. Further, the trapezoidal heat conduction plate, the installation folding edge and the conduction folding edge are installed on the main installation bin, which is convenient for disassembly and use. On this basis, the locking block, the second locking bolt and the rubber cushion block are provided to squeeze the conduction folding edge to fit with the temperature conduction block to ensure the heat conduction efficiency;

[0027] 3. The stranded wire assembly, the gantry plate and the insertion pin are also provided. The inner core body is inserted into the inside of the inner cylinder. Through the rotation of the inner cylinder and the limiting pin, the metal wires composed of the inner core bodies rotate and wind around each other to realize stranding. Compared with manual twisting and stranding, the rotation of the inner cylinder and the limiting pin makes the stranding more stable, ensuring that the thickness of the inner core body is uniform after stranding and reducing the manual error. Further, when the wiring assembly is connected to the inner core body, on the basis of the gantry plate pressing down the inner core body, the insertion pin is inserted into the inside of the inner core body. Compared with directly pressing the inner core body, the insertion pin cooperates with the stranded inner core body, avoiding the loosening or being pulled at the end, and further improving the stability of the connection.

[0028] 4. A fire prevention component is provided. When a fire breaks out due to excessive temperature at the connection between the inner core and the electro-conductive plate, the fire heats the melamine cyanurate inside the first box body, generating nitrogen and ammonia, increasing the internal pressure of the second box body, causing the moisture-proof film to fall off, and the powdered fire extinguishing agent inside the second box body to be discharged from the inclined guiding channel, playing a preliminary fire extinguishing role. Further, nitrogen and ammonia are non-combustible, reducing the oxygen concentration and assisting in fire extinguishing. Moreover, ammonia has a pungent odor, and after spreading, it can play a warning role, facilitating users to replace and repair in a timely manner.

[0057] The movable part has a first state and a second state. When in the first state, the bottom end of the movable clamping plate 36 abuts against the top end of the fixed clamping plate 320, and when in the second state, the bottom end of the movable clamping plate 36 abuts against the top end of the fixed clamping plate 320;

[0059] Reference Figure 1 、 Figure 2 and Figure 3 As shown, by pressing down the movable cutting plate 35, the bottom end of the movable clamping plate 36 abuts against the top end of the fixed clamping plate 320, and the movable part is in the first state. The movable cutting plate 35 and the fixed cutting plate 319 are used in cooperation to cut the sheath of the flexible cable or the outer skin of the inner core. Then, pull up the movable cutting plate 35 to drive the movable clamping plate 36 to move downward, so that the bottom end of the movable clamping plate 36 abuts against the top end of the fixed clamping plate 320, and the movable part is in the second state. The flexible cable sheath or the outer skin of the inner core can be fixed by pressing and clamping through the movable clamping plate 36 and the fixed clamping plate 320, thereby realizing the adjustment of the length of the flexible cable. When the cable connector plug is damaged, only the wiring component 1 needs to be replaced. When the end of the flexible cable is damaged or the length of the flexible cable needs to be adjusted, the redundant outer skin and sheath can be removed through the stripping component 3, so that the flexible cable can be reconnected to the wiring component 1, effectively reducing the use cost of the flexible cable; In addition, users do not need to carry additional cutting tools, which improves the convenience of reusing the flexible cable and the connecting device, and makes the use more flexible;

[0060] Optionally, the number of the cutting grooves 37 and the clamping grooves 38 cooperating with the outer skin of the inner core of the flexible cable is set to be multiple to ensure that multiple outer skins of the inner cores are cut and clamped at the same time. Among them, the cooperation means that the inner diameter of the clamping groove 38 fits the outer diameter of the sheath or the outer skin of the inner core to ensure the clamping effect, and the inner diameter of the cutting groove 37 fits the inner diameter of the sheath or the outer skin of the inner core to ensure sufficient cutting. Further optionally, an arc-shaped clamping strip 321 with a right-angled triangle cross-section is provided on the inner wall of the clamping groove 38.

On the other hand, one right-angled side of the triangle fits the inner wall of the clamping groove 38, and there is a clamping angle between the hypotenuse and the right-angled side. The opening of the clamping angle faces the side of the wiring component 1, which is convenient for the flexible cable to be pushed toward the side close to the wiring component 1 and has the function of being difficult to move away from the side of the wiring component 1.

[0061] In some embodiments, the movable part further includes a mounting frame 31 sleeved outside two movable clamping plates 36, and adjusting cylinders 33 arranged on both sides of the middle part of the movable cutting plate 35 along the first direction.

[0062] Reference Figure 2 and Figure 3 , the adjusting cylinder 33 is sleeved on the fixed shaft 32. The two ends of the fixed shaft 32 are connected to the mounting frame 31. When the movable cutting plate 35 moves downward, its transmission tooth groove 322 drives the transmission strip 34 to move, and then drives the fixed shaft 32 and the adjusting cylinder 33 to rotate. Further, the transmission strip 34 of the rotating adjusting cylinder 33 is caught in the transmission tooth groove 322 on the side surface of the movable clamping plate 36, and then drives the movable clamping plate 36 to move upward, thereby achieving the purpose of synchronous and reverse movement of the movable clamping plate 36 and the movable cutting plate 35. Optionally, the front and back surfaces and the side surface far from the transmission tooth groove 322 of the movable clamping plate 36 are all attached to the inner wall of the mounting frame 31 to improve the stability of the movement of the movable clamping plate 36. Further optionally, a pressing plate 310 is provided at the top end of the movable cutting plate 35 to facilitate the pressing and pulling of the movable cutting plate 35.

Moreover, the second spring 312 drives the positioning plug 314 to insert into the positioning slot 316 to achieve fixation. When releasing the fixation, only need to pull the positioning plug 314, the second spring 312 is stretched, and the positioning plug 314 disengages from the positioning slot 316. At this time, press down the pressing plate 310, drive the movable cutting plate 35 to move downward, and the movable clamping plate 36 to move upward, then the positioning lock can be released;

[0066] Among them, several first fixing plates 311 are provided at the top end of the mounting frame 31. A second spring 312 is provided at the end of each first fixing plate 311 away from the movable cutting plate 35. The ends of the second springs 312 away from the first fixing plates 311 are connected to the same second linkage plate 313, and the positioning plug 314 is arranged on the second linkage plate 313, which is convenient for driving the synchronous movement of multiple positioning plugs 314, improving the stability after positioning and plugging, and the convenience of synchronous operation of multiple positioning plugs 314. Further, a second fixing plate 315 is provided at the position corresponding to the positioning plug 314 at the top end of the mounting frame 31. A channel for the positioning plug 314 to penetrate is provided in the middle of the second fixing plate 315, which is used to limit the one-way movement of the positioning plug 314 and reduce the inaccurate insertion caused by shaking.

The shape of the functional cushion strips 318 is triangular. On the one hand, cooperating with the guiding inclined surface 317, during the downward movement of the first linkage plate 39, the positioning plug 314 is pushed away through the guiding inclined surface 317, and then driven by the second spring 312 to reset and insert into the positioning slot 316. On the other hand, the functional cushion strips 318 cooperate with the first linkage plate 39 to seal the opening on the mounting frame 31, playing a sealing role.

[0068] In some embodiments, the connecting device further includes side connecting components 2 arranged on both sides of the wiring component 1 along the first direction. The side connecting components 2 include main installation bins 21. The mounting frame 31 penetrates through the top of the main installation bins 21, and the fixed cutting plate 319 and the fixed clamping plate 320 are both arranged on the inner bottom surface of the main installation bins 21.

[0069] Such as Figure 1 and Figure 4As shown, the installation of the peeling component 3 is realized. The main installation bin 21 corresponds to two peeling clamping structures, which respectively correspond to the sheath of the flexible cable and the outer skin of the inner core body, ensuring convenience during use. At the same time, through the main installation bin 21 and the wiring component 1, it is avoided that the separation part of the sheath and the inner core body of the flexible cable is exposed to the air, reducing the damage to the separation part by substances such as dust in the air.

[0070] In some embodiments, the wiring component 1 includes a U-shaped plate 11. An insulating plate 12 is provided on the inner bottom surface of the U-shaped plate 11. A vertical plate 13 is provided at the top middle of the insulating plate 12. A horizontal plate 14 is provided at the top of the vertical plate 13. The insulating plate 12, the vertical plate 13, and the horizontal plate 14 all extend along the third direction. Two fixing groups are provided on the horizontal plate 14 along the first direction. Each fixing group includes first locking bolts 15 that are arranged along the third direction and are threadedly connected and installed through the horizontal plate 14. An electric conduction plate 111 is provided at the position below the corresponding first locking bolts 15 among the two fixing groups at the top of the insulating plate 12;

[0071] As Figure 6 Figure 7 and Figure 8 shown, by rotating the first locking bolt 15, the inner core body is pressed against the surface of the electric conduction plate 111 under the action of the thread, realizing the connection between the inner core body and the wiring component 1. The inner core bodies of the two flexible cables are respectively fixed by the first locking bolts 15 of the two fixing groups, and electric data conduction is carried out through the electric conduction plate 111 to realize the basic electric data conduction function. And there is an opening above the U-shaped plate 11, which is convenient for the user to screw the first locking bolt 15.

The inner walls of each limiting channel 16 fit with the outer walls of the bottoms of each U-shaped plate 17;

[0073] As Figure 6 、 Figure 7 and Figure 8As shown, by inserting the pin 110 into the stranded inner core body, the pressing efficiency is improved, and the situation of unstable connection caused by the deformation of the inner core body is reduced. Further, the stability of the operation of the pin 110 is ensured by the portal plate 17 and the limiting channel 16, and the situation of oblique insertion or position deviation will not occur. Further still, the portal plate 17 is connected by the connecting plate 18 and the first spring 19. When the first locking bolt 15 is screwed upward, the first spring 19 will drive the connecting plate 18 and the portal plate 17 to move upward synchronously, and the inner core body can be taken out without manually removing the pin 110. Moreover, the pin 110 and other components are all above the electric conduction plate 111, which is convenient for continued use next time.

[0074] In some embodiments, the side connection assembly 2 further includes a shielding plate 22 provided at the top of the main installation bin 21 on the side close to each other. The shielding plate 22 covers the upper part of the U-shaped plate 11. The connection device further includes a locking assembly 7. The locking assembly 7 is used to drive the two main installation bins 21 to approach each other and lock, and connect the U-shaped plate 11 and the shielding plate 22.

[0075] As Figure 1 , Figure 5 and Figure 6 As shown, first, the upper opening of the U-shaped plate 11 is shielded by the shielding plate 22 to prevent the internal structure of the wiring assembly 1 from being exposed. Secondly, the locking assembly 7 includes end caps 71 provided at the mutually remote ends of the two main installation bins 21. A wire passing hole 72 is also provided in the middle of the end cap 71 for the sheath of the flexible cable to pass through. First ear plates 73 are symmetrically arranged on the end cap 71. The long bolt 74 passes through the ear holes of the two first ear plates 73 corresponding to the two end caps 71, and then the nut 75 is used to cooperate with the long bolt 74 to lock, so as to realize the purpose that the end cap 71 drives the two main installation bins 21 to approach each other and is locked by the cooperation of the nut 75 and the long bolt 74. Further, second ear plates 76 are provided on the outer surface of the top of the U-shaped plate 11 and the side surface of the shielding plate 22, and the U-shaped plate 11 and the shielding plate 22 can be connected by passing the bolt group through the second ear plates 76 to prevent the U-shaped plate 11 from falling down from the middle. Preferably, sealing gaskets are embedded in the mutually remote ends of the two main installation bins 21, the inner wall of the wire passing hole 72, the top of the U-shaped plate 11, and the left and right side surfaces of the U-shaped plate 11 in contact with the main installation bin 21. The connection gaps are sealed by the deformation of the sealing gaskets to improve the internal sealing and independence of the connection device after assembly.

[0076] In some embodiments, a fire prevention component 4 is provided at the top of the main installation bin 21. The fire prevention component 4 includes a first box body 41 penetrating through the shielding plate 22, and a second box body 45 penetrating through the top of the main installation bin 21. A communication pipe 44 for communicating the internal spaces of the two is provided between the first box body 41 and the second box body 45.

[0077] A temperature conduction sheet 43 is provided at the bottom of the first box body 41. Cyanuric acid melamine salt 42 is provided inside the first box body 41. Powdered fire extinguishing agent 46 is provided inside the second box body 45. An inclined guiding channel 47 that can communicate with the main installation bin 21 is provided at the bottom of the second box body 45. A moisture-proof film 48 is adhered to the bottom end of the inclined guiding channel 47;

[0078] As Figure 4 and Figure 5 shown, when the temperature at the connection between the inner core body and the electric conduction plate 111 is too high to form an open flame, the open flame will heat the cyanuric acid melamine salt 42 inside it through the temperature conduction sheet 43 at the bottom of the first box body 41. After being heated, the cyanuric acid melamine salt 42 generates nitrogen and ammonia. Through the connection function of the connecting pipe 44, the internal pressure of the first box body 41 and the second box body 45 increases. The air pressure drives the moisture-proof film 48 to fall off, and the powdered fire extinguishing agent 46 inside the second box body 45 is discharged from the inclined guiding channel 47, playing a preliminary fire extinguishing role. Further, nitrogen and ammonia are non-combustible, reducing the oxygen concentration and assisting in fire extinguishing. Moreover, ammonia has a pungent smell, and after overflowing, it can play a warning role, facilitating users to replace and repair in time; Further optionally, there are two inclined guiding channels 47, one inclined towards the wiring assembly 1 side and one inclined towards the end cover 71 side, achieving a fast and comprehensive coverage effect.

[0079] In some embodiments, the connecting device further includes a heat dissipation component 5, and the heat dissipation component 5 includes:

[0080] A heat conduction part is provided at the bottom of the U-shaped plate 11, including a temperature conduction strip 53 in contact with the bottom surface of the electric conduction plate 111, and several temperature conduction blocks 54 that conduct heat transfer with the temperature conduction strip 53;

[0081] Several heat exchange parts are provided at the bottom of the main installation bin 21, including two installation flanges 56 connected to the bottom surface of the main installation bin 21. A trapezoidal heat conduction plate 55 is provided between the two installation flanges 56. A conduction flange 57 is formed by bending the installation flange 56 near the temperature conduction block 54 side;

[0082] Several connecting parts are respectively provided on the corresponding trapezoidal heat conduction plates 55, and are used to drive the conduction flange 57 and the temperature conduction block 54 to fit together;

[0083] As Figure 8 、 Figure 9 、 Figure 10 and Figure 11As shown, through the cooperation of the temperature conduction strip 53 and the temperature conduction block 54, the heat generated by the electric conduction plate 111 is transferred to the temperature conduction block 54, and then the conduction folding edge 57 is driven by the connecting part to fit with the temperature conduction block 54, so that the heat is transferred to the trapezoidal heat conduction plate 55, the installation folding edge 56 and the conduction folding edge 57. By increasing the contact area with the air, the purpose of improving the heat dissipation efficiency is achieved. Optionally, a liquid storage box 51 filled with condensate 52 is provided at the bottom of the U-shaped plate 11. The temperature conduction strip 53 is disposed through the top end of the liquid storage box 51, and passes through the U-shaped plate 11 and the insulating plate 12 to the electric conduction plate 111, while the temperature conduction block 54 is disposed on the side surface of the liquid storage box 51, which is convenient for contacting with the heat exchange part installed on the ground of the main installation bin 21.

[0084] In some embodiments, the connecting part includes a locking block 58 slidably installed on the trapezoidal heat conduction plate 55. The middle part of the locking block 58 has a fitting trapezoidal groove 59 that fits with the outer surface of the trapezoidal heat conduction plate 55. A second locking bolt 510 is connected through the middle part of the locking block 58 by a thread. A rubber cushion block 511 is provided at the end of the second locking bolt 510 close to the trapezoidal heat conduction plate 55. By rotating the second locking bolt 510, under the action of the thread, the rubber cushion block 511 is driven to abut against the trapezoidal heat conduction plate 55. Through the action of static friction, the stability of the locking block 58 is ensured, so that the locking block 58 can push the conduction folding edge 57 to fit with the temperature conduction block 54, and thus the purpose of stable heat conduction is achieved. Optionally, a heat conduction silicone grease is provided between the conduction folding edge 57 and the temperature conduction block 54, and the two are connected by a soft material to improve the heat conduction efficiency.

[0085] In some embodiments, the connecting device further includes a stranded wire assembly 6. The stranded wire assembly 6 includes a sleeve 61. An internally rotatable inner cylinder 63 is disposed through the inside of the sleeve 61. An installation groove 65 is provided on the outer surface of the inner cylinder 63. A limiting through hole 67 penetrating to the inside of the inner cylinder 63 is provided on the inner surface of the installation groove 65. An installation strip 66 is installed inside the installation groove 65. A limiting pin 68 is provided at the position of the installation strip 66 corresponding to the limiting through hole 67. A pick-up slot 62 having the same width as the installation strip 66 is provided on the outer surface of the sleeve 61;

[0086] As Figure 12 and Figure 13As shown, insert the inner core into the inner cylinder 63, then snap the mounting strip 66 into the mounting groove 65, so that the limit pin 68 passes through the limit through-hole 67. Then rotate the inner cylinder 63, and the limit pin 68 will drive the metal wires composed of the inner core to rotate and wind around each other to achieve stranding. Compared with manual twisting and stranding, the rotation of the inner cylinder 63 and the limit pin 68 makes the stranding more stable, ensuring that the overall thickness of the inner core is uniform after stranding, reducing manual errors. Further, after stranding, align the mounting groove with the object-taking notch 62, and then the mounting strip 66 and the limit pin 68 can be taken out, which will not interfere with the extraction of the inner core. When the wiring component 1 is connected to the inner core, on the basis of the gantry plate 17 pressing down on the inner core, the insertion pin 110 is inserted into the inner core. Compared with directly pressing the inner core, the insertion pin 110 cooperates with the stranded inner core to avoid loosening or being pulled at the end, further improving the stability of the connection. Optionally, the sleeve 61 is provided at the top or side of the pressing plate 310 for the convenience of the user; preferably, a limit post 64 is provided on the outer surface of the inner cylinder 63, and the outer surface of the limit post 64 fits with the end face of the sleeve 61 to prevent the inner cylinder 63 from detaching from the inside of the sleeve 61.
