DETAILED DESCRIPTION

[0022] The preferred technical solutions of the present invention are described in detail below with reference to the accompanying drawings.

[0023] When using a crimping connector to connect rubber insulated cables, workers usually need to manually cut off the outer sheath and then use the connector for wiring.

The cutting piece 5 is composed of a first slider, a connecting rod, a tool, a long arc plate and a shielding plate, wherein the tool is a triangular prism, and two of the side surfaces are arc surfaces, which are used to fold the cut insulating cortex outward to facilitate the shielding plate to block it, and the shielding plates on the adjacent four cutting pieces 5 together form a trumpet shape, and the long arc plate is used to fix the cable. Position, the front and rear sides of the inside of the junction box 1 are fixed with two guide rail blocks 6 that are symmetrically distributed on the left and right, and there is a certain distance between the two adjacent guide rail blocks 6.

The cylinder 8 is composed of a body and a circular ring on the outer periphery. The circular ring of the cylinder 8 is rotatably connected to the second sliders on the two adjacent sliding frames 7. The first sleeve 9 is located on one side of the rectangular ring fixed to the cover plate 2. The first sleeve 9 has a notch. The cover plate 2 is fixed with two first sleeves 9 that are symmetrically distributed on the left and right. The two first sleeves 9 adjacent to the cylinder 8 are respectively located above and below the cylinder 8. The sliding column 10 is provided for the conductor to be provided. When current passes through, a gap with the same width as the second conductor 13 is provided in the middle of the first conductor 12, so that the second conductor 13 can slide in the gap. Both the first conductor 12 and the second conductor 13 are arc-shaped, so that the wire core can be converged when the two move toward each other. The projection shapes of the first conductor 12 and the second conductor 13 on the side of the through hole provided in the junction box 1 are the same, so that the upper and lower sides of the wire core are subjected to the same extrusion force, thereby enhancing the stability of the wire core. The length of the wire 14 in the figure is only for reference, and the length of the wire 14 can be adjusted according to actual usage. The sealing cover 15 is composed of a round tube and a rubber film with a through hole. The inner diameter of the round tube of the sealing cover 15 is the same as the outer diameter of the fixing ring 4, so as to enhance the sealing performance.

[0026] like Figure 5-Figure 8As shown, the adjustment component includes: a cylinder 1701, which is fixed to the cutting piece 5, a rotating ring 1702 is rotatably connected to the junction box 1, and the rotating ring 1702 is provided with an oblique slide groove. The cylinder 1701 and the oblique slide groove of the rotating ring 1702 are slidably matched, and there is damping between the rotating ring 1702 and the junction box 1, and the rotating ring 1702 is fixed with a plurality of limit blocks 1703. The junction box 1 is slidably connected to an L-shaped plate 1704, and a second spring 1705 is fixed between the L-shaped plate 1704 and the junction box 1, and the elastic coefficient of the second spring 1705 is greater than the elastic coefficient of the torsion spring 1707. The L-shaped plate 1704 is limited in rotation and connected to the limit plate 1706, and a torsion spring 1707 is fixed between the L-shaped plate 1704 and the limit plate 1706; a regular component, the number of which is two, which are respectively arranged on the cover plate 2, and are used to ensure that the wire core will not loosen after the insulation skin is stripped off.

[0027] In the above scheme, an adjustment component is taken as an example for description: the number of cylinders 1701 is consistent with that of the cutting piece 5, and the cylinders 1701 are located on the side of the slider on the cutting piece 5 close to the junction box 1. The inner diameter of the rotating ring 1702 is equal to the inner diameter of the through hole of the junction box 1. The outer circumferential surface of the rotating ring 1702 is fixedly connected with a wavy ring to facilitate twisting of the rotating ring 1702. A plurality of limit blocks 1703 are evenly distributed on the outer side of the rotating ring 1702 in the circumferential direction. The limit blocks 1703 are provided with a flat surface and an arc surface, and the flat surface is used to be aligned with the limit plate. 1706 cooperates to limit the rotation direction of the rotating ring 1702, the L-shaped plate 1704 is composed of a plate parallel to the left and right sides of the junction box 1 and a plate perpendicular to the left and right sides of the junction box 1, the plate perpendicular to the left and right sides of the junction box 1 is limited by the limiting plate 1706 and is convenient for pulling the L-shaped plate 1704 upward, the second spring 1705 is located in the rectangular notch of the junction box 1, the limiting plate 1706 is provided with a flat surface and an arc surface, and the plane on the limiting plate 1706 is used to limit and cooperate with the plane of the adjacent limiting block 1703.

[0028] like Figure 3 , Figure 7 and Figure 8As shown, the regular assembly includes: at least two second sleeves 1801, which are respectively fixed to adjacent cover plates 2, the second sleeves 1801 are slidably connected with sliding pins 1802, the cylinder 8 is provided with inclined grooves with the same number as the sliding pins 1802, the sliding pins 1802 are slidably matched with the adjacent inclined grooves on the cylinder 8, a third spring 1803 is fixed between the second sleeve 1801 and the sliding pin 1802, and a plurality of fourth springs 1804 are fixedly connected to the inner wall of the cylinder 8. The fourth spring 1804 is fixedly connected to the clamp 1805; the clamp 1805 is provided with a plurality of friction strips, and the first limiting rod 1806 is fixedly connected to the sliding frame 7, and the shortest distance from the first limiting rod 1806 to the inner side surface corresponding to the adjacent through hole on the junction box 1 is greater than the shortest distance from the cylinder 8 to the inner side surface corresponding to the adjacent through hole on the junction box 1, and the sliding column 10 is fixedly connected to the second limiting rod 1807, and the first limiting rod 1806 and the adjacent second limiting rod 1807 are limited and matched.

[0029] In the above scheme, a regular component is taken as an example for description: there are two second sleeves 1801, and the two second sleeves 1801 are respectively fixed to one side of the rectangular ring fixed to the upper and lower cover plates 2. The second sleeve 1801 is provided with a notch. The sliding pin 1802 is composed of a cylinder and a cylindrical pin. The diameter of the cylinder is larger than the diameter of the cylindrical pin, which enhances the bending resistance of the sliding pin 1802. The third spring 1803 is in a compressed state when the cover plate 2 is in contact with the junction box 1. The fourth spring 1804 is located inside the cylinder 8. The number of the fourth springs 1804 is three evenly distributed circumferentially. The clamp 1805 is composed of an arc plate and a fan plate. There is a certain angle between the arc plate and the fan plate. The three fan plates are tightly attached to form a shape similar to a truncated cone ring. A number of friction strips are located on the concave surface of the arc plate. The friction strips are long strips and are used to increase the friction force on the wire core during rotation.

[0030] When the device is used to connect two sections of cables, the following description is made by taking the placement of the cables on the right side as an example: the staff first removes the sealing cover 15, and while ensuring that the sliding pin 1802 is in contact with the oblique groove on the cylinder 8, pulls the two cover plates 2 in a direction away from the junction box 1, and then passes the cable through the through hole on the sealing cover 15. Subsequently, according to the size of the inner diameter of the cable insulation, the staff twists the rotating ring 1702 counterclockwise (taking the right view as an example), and the four oblique grooves on the rotating ring 1702 squeeze the adjacent cylinders 1701 respectively. The cylinders 1701 are squeezed and slide along the adjacent oblique grooves on the rotating ring 1702. The cylinders 1701 drive the adjacent cutting pieces 5 to slide toward the outside of the fixed ring 4, and the four cutting pieces 5 slide outward, changing the inner diameter of the circle corresponding to the four cutting pieces 5 until it is consistent with the size of the inner diameter of the cable insulation. The staff then stops twisting the rotating ring 1702.

[0031] When the rotating ring 1702 is twisted, the rotating ring 1702 drives several limit blocks 1703 evenly distributed on its circumference to rotate counterclockwise, and the several limit blocks 1703 rotate counterclockwise and squeeze the limit plate 1706 in turn. The limit plate 1706 is squeezed and swings clockwise. The swing of the limit plate 1706 causes the torsion spring 1707 to twist. When the limit block 1703 releases the squeeze on the limit plate 1706, the limit plate 1706 is reset under the action of the elastic force of the torsion spring 1707. As the several limit blocks 1703 intermittently squeeze the limit plate 1706, the above action is repeated continuously.

[0032] After adjusting the positions of the four cutting pieces 5, the staff fits the inner side of the cable insulation skin with the outer side of the arc-shaped plates on the four cutting pieces 5, and then continues to push the cable to the left. The insulation skin of the cable is cut into four strips by the cutter on the cutting piece 5. The cable continues to move to the left, and the four insulation strips are folded and piled on the shielding plate under the obstruction of the shielding plate on the cutting piece 5, and the core of the cable continues to move to the left through the shielding plate.

[0033] When the wire core moves to the left, the wire core gradually contacts the three clamps 1805 . The three clamps 1805 move toward the inner wall of the cylinder 8 under the pressure of the wire core. At the same time, the clamps 1805 squeeze the wire core under the action of the adjacent fourth spring 1804 .

[0034] When the wire core contacts the left side wall inside the cylinder 8, the wire core continues to move leftward, the wire core squeezes and drives the cylinder 8 to move leftward, and the cylinder 8 drives two adjacent sliding frames 7 to slide leftward along the adjacent guide rail blocks 6 respectively.

[0035] When the cylinder 8 moves to the left, the two sliding grooves on the cylinder 8 begin to rotate counterclockwise under the limit of the adjacent sliding pin 1802, and the cylinder 8 drives the three fourth springs 1804 to rotate counterclockwise, and the fourth spring 1804 drives the adjacent clamp 1805 to rotate counterclockwise. The clamp 1805 drives the wire core to rotate counterclockwise under the action of the friction strip thereon, and the wire core rotates counterclockwise and is twisted together to ensure that the wire core and the conductor are in more complete contact.

[0036] When the two sliding frames 7 slide to the left, the sliding frames 7 drive the two adjacent first limiting rods 1806 to move to the left. After the first limiting rod 1806 moves to the left to a certain distance and releases the limiting of the adjacent second limiting rod 1807, the first conductor 12 moves upward driven by the elastic force of the adjacent first spring 11, and the second conductor 13 moves downward driven by the elastic force of the adjacent first spring 11. The first conductor 12 and the adjacent second conductor 13 move toward each other and gradually contact the twisted core, and then squeeze the core to fix it. At this time, the left and right second conductors 13 are connected to the left and right first conductors 12 through the adjacent wires 14 respectively.

[0037] When the two sliding frames 7 slide to the left to the limit position along the guide block 6, the staff stops pushing the cable to the left to complete the connection of the cable on the right side of the device and repeats the above action, but the pushing direction of the cable and the horizontal moving direction of the parts are opposite to the above direction to complete the connection of the cable on the left side of the device, and then presses down the cover plate 2 on the upper side of the junction box 1. The cover plate 2 moves downward, driving the two adjacent first sleeves 9 and two second sleeves 1801 symmetrically distributed on the left and right to move downward. The sliding pin 1802 remains stationary under the limit of the cylinder 8, and the second sleeve 1801 moves downward to compress the adjacent third spring 1803. The elastic force generated by the extrusion of the third spring 1803 reacts to the adjacent second sleeve 1801 and the adjacent sliding pin 1802, increasing the extrusion force of the sliding pin 1802 on the adjacent cylinder 8 bevel to prevent the cylinder 8 from rotating. , the second conductor 13 remains stationary under the limitation of the core, the first sleeve 9 moves downward to compress the adjacent first spring 11, and the elastic force generated by the extrusion of the first spring 11 reacts on the adjacent first sleeve 9 and the second conductor 13, thereby strengthening the extrusion of the core by the second conductor 13. When the lower side of the cover plate 2 contacts the upper side of the junction box 1, stop pressing the cover plate 2 to complete the fixation of the upper cover plate 2, and then press the lower cover plate 2 upward to repeat the above actions, but the movement directions of the relevant parts are opposite, and the movement of the second conductor 13 is changed to the movement of the first conductor 12. The first conductor 12 and the second conductor 13 move toward each other, thereby strengthening the extrusion force of the first conductor 12 and the second conductor 13 on the core. After the fixation of the upper and lower cover plates 2 is completed, the two sealing covers 15 are respectively installed on the two fixing rings 4 to complete the wiring of the cable.

[0038] When the cable needs to be removed, the reset of the parts on the right side of the junction box 1 is taken as an example: first, the sealing cover 15 is removed from the fixing ring and temporarily left on the cable, and then the upper cover plate 2 is pulled upward. The cover plate 2 moves upward, driving the two symmetrically distributed first sleeves 9 and the two symmetrically distributed second sleeves 1801 to move upward. The first sleeve 9 and the second sleeve 1801 move upward to gradually release the squeezing of the adjacent first spring 11 and the adjacent third spring 1803, and drive the adjacent sliding pin 1802 to move upward through the adjacent first spring 11, and drive the adjacent second conductor 13 to move upward through the adjacent third spring 1803, until the upper cover plate 2 is separated from the junction box 1, repeat the above action to pull the lower cover plate 2 downward, but the movement direction of the relevant parts is opposite, and the movement of the second conductor 13 is changed to the movement of the first conductor 12.

[0039] Then, the two sliding frames 7 are pushed to the right, and the sliding frames 7 move to the right, driving the cylinder 8 to move to the right until it moves to the initial position, and then the cylinder 8 is rotated to the initial position, and then the clamp 1805 is pushed outward and the wire core is moved to the right until the wire core is out of contact with the cutting piece 5.

[0040] After the wire core is taken out, pull the L-shaped plate 1704 upwards and twist the rotating ring 1702 clockwise (taking the right view as an example) until the cutting piece 5 returns to its initial position. Repeat the above actions for the reset of the left part, but the pulling direction of the cable and the horizontal movement direction of the part are opposite to the above directions. Finally, remove the two sealing covers 15 from the cable and install them on the two fixing rings 4 respectively to complete the reset of the device.

[0041] When the existing wiring device is in use, the cover plate is usually connected by a threaded connection to close the wiring box, which requires aligning the threaded holes and turning the screws, which is cumbersome and has low wiring efficiency.

[0042] Embodiment 2: Based on embodiment 1, Figure 9-11 As shown, it also includes: a locking assembly, which is in a plurality of pieces and is all arranged on the two cover plates 2. The locking assembly is used to lock the junction box 1 with the two cover plates 2. The locking assembly includes: a composite slider 1901, which is in two pieces and is rotatably connected to the adjacent cover plates 2 respectively. A rectangular block 1902 is fixedly connected to the inner wall of the junction box 1. The rectangular block 1902 is rotatably connected to two limiting columns 1903.

[0043] In the above scheme, a locking component is described as an example: the composite slider 1901 is composed of a cylindrical block and a rectangular column. The cylindrical block of the composite slider 1901 is rotatably connected to the adjacent cover plate 2. The rectangular block 1902 is located between two adjacent guide rail blocks 6. The limiting column 1903 has a rectangular hole. The rectangle corresponding to the rectangular hole of the limiting column 1903 is equal in size to the rectangle corresponding to the rectangular column of the composite slider 1901. The limiting column 1903 is provided with a plurality of arc-shaped notches distributed in a linear array. An arc surface is provided at the transition between the arc-shaped notch of the limiting column 1903 and the area where the limiting column 1903 does not have a notch, which is used for extrusion locking. Block 1904 causes the locking block 1904 to slide, thereby releasing the limitation between the locking block 1904 and the limiting column 1903. The locking block 1904 is composed of a rectangular block and arc blocks distributed in a linear array. The distance between two adjacent arc blocks on the locking block 1904 is equal to the distance between two adjacent arc notches on the limiting column 1903. The number of arc blocks on the locking block 1904 is less than the number of arc notches on the limiting column 1903. The sliding distance of the locking block 1904 on the cover plate 2 is greater than the width of the arc block on the locking block 1904, which is used to ensure that the locking block 1904 can release the limitation with the limiting column 1903.

[0044] Repeat the actions of Example 1 and take the movement of the upper side cover plate 2 as an example to describe: when the cover plate 2 is pressed downward, the cover plate 2 drives the two composite sliders 1901 to move downward, and the rectangular sliders of the composite sliders 1901 slide downward along the rectangular slide grooves of the adjacent limiting columns 1903 and limit the rotation of the adjacent limiting columns 1903. The cover plate 2 moves downward and drives the two locking blocks 1904 to move downward. The locking blocks 1904 move downward, and the arc blocks thereon contact with the grooves of the adjacent limiting columns 1903 in turn. The limiting columns 1903 squeeze the arc blocks on the adjacent locking blocks 1904. The two locking blocks 1904 are squeezed and move toward each other and squeeze the adjacent fifth springs 1905 respectively. When the limiting columns 1903 release the squeezing of the adjacent locking blocks 1904, the locking blocks 1904 are reset under the action of the elastic force of the adjacent fifth springs 1905. The movement of the lower side cover plate 2 repeats the above actions, but the longitudinal movement directions of the relevant parts are opposite.

[0045] When the cover plate 2 moves to the specified position, all the arc blocks on the locking block 1904 are located in the arc notches on the adjacent limiting columns 1903, completing the locking of the cover plate 2. When the extrusion pressure between the second conductor 13 and the adjacent first conductor 12 increases, the cover plate 2 will not fall off the junction box 1 under the influence of the reaction force.

[0046] When it is necessary to remove the upper cover plate 2 from the junction box 1, the staff rotates the upper composite slider 1901, and the composite slider 1901 drives the adjacent limiting column 1903 to rotate. The limiting column 1903 rotates and squeezes several arc blocks on the adjacent locking block 1904. The locking block 1904 is squeezed to slide in the direction away from the adjacent limiting column 1903 and squeezes the adjacent fifth spring 1905, gradually releasing the lock between the locking block 1904 and the adjacent limiting column 1903. When the composite slider 1901 is rotated to 180°, repeat the above action and continue to rotate the other composite slider 1901 on the upper side. After completing the rotation of the two composite sliders 1901, pull out the upper cover plate 2 upwards, repeat the above action, but the longitudinal movement direction of the relevant parts is opposite, and take out the lower cover plate 2, so that the device is easier to install and remove while ensuring the sealing, simplifying the operating steps and improving the wiring efficiency.

[0047] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
