[0019] Reference Figure 1-Figure 6On the one hand, in order to achieve the above-mentioned purpose, the present invention provides a high-voltage through-hole connector, including: a connecting seat 1, a first sealing ring 2, a mounting seat 3, a sealing connector 4 and a driving member 5. The high-voltage through-hole connector usually needs to be installed at the through-hole of a building, equipment or other obstacles to facilitate the wiring of cables. The connecting seat 1 is provided with a through-hole 11 for the cable to pass through, and one end of the connecting seat 1 has a fixing seat 14.

[0020] By installing the connecting seat 1 at the through hole of a building, equipment or other obstacle, so that the axis of the through hole and the through hole 11 are on the same straight line, and then the mounting seat 3 is installed at the corresponding position of the cable, and the sealing connector 4 is driven by the driving member 5 to insert into the through hole 11, the sealing connector 4 abuts against the end of the first sealing ring 2, so that a first seal is formed between the first sealing ring 2 and the cable, and a second seal is formed between the mounting seat 3 and the cable, and a third seal is formed between the sealing connector 4 and the first sealing ring 2, so that the installation of the cable has multiple sealing effects, which is not only beneficial to improve the protection of the cable, but also improves the installation stability of the cable, and through splicing, the assembly of the through-hole connector and the cable can also be quickly realized.

[0021] Reference Figure 5-Figure 6 According to some embodiments of the present invention, the first sealing ring 2 is provided with a hollow groove 21, and the hollow groove 21 is arranged along the circumference of the first sealing ring 2. The inner wall of the first sealing ring 2 is provided with a plurality of coaxially arranged sealing rings 22, and the plurality of sealing rings 22 are arranged at intervals along the axial direction of the first sealing ring 2.

[0024] In some specific examples, the cross section of the mounting groove 12 is a polygon, specifically, the cross section of the mounting groove 12 can be a quadrilateral, and the mounting portion 31 is plugged into the mounting groove 12, which can improve the connection reliability between the connecting seat 1 and the mounting seat 3, so that the mounting portion 31 cannot rotate relative to the connecting seat 1. The groove diameter of the mounting groove 12 is larger than the groove diameter of the through hole 11, so that the mounting portion 31 is plugged into the mounting groove 12, and the mounting seat 3 abuts against the end surface of the connecting seat 1, so that the mounting seat 3 can be positioned.

[0025] Reference Figure 4-Figure 6 According to some embodiments of the present invention, the sealing connector 4 includes: a plurality of clamping parts 41 and a third sealing ring 42. The plurality of clamping parts 41 are used to clamp the cable together. Specifically, the clamping part 41 has a first end and a second end. The first end is a fixed end and the second end is a movable end. The fixed end is connected to the mounting seat 3, and the movable end extends horizontally to the side away from the mounting seat 3. The clamping part 41 has elastic deformation performance. The movable ends of the plurality of clamping parts 41 can move along the radial direction of the cable and clamp the cable. The clamping part 41 can clamp the cable under the pressure of the hole wall of the perforation 11. The third sealing ring 42 is arranged at the end of the mounting seat 3 and abuts against the connecting seat 1. The clamping and fixing of the cable is realized by the plurality of clamping parts 41, so that the mounting seat 3 and the cable are not easily offset, and the stability of the cable installation is improved. In addition, the third sealing ring 42 is arranged at the end of the mounting seat 3 and abuts against the connecting seat 1, which can further improve the sealing between the mounting seat 3 and the connecting seat 1.

[0026] In some examples, when the sealing connector 4 is fully inserted into the through hole 11, the end surface of the mounting seat 3 abuts against the end of the connecting seat 1, and the third sealing ring 42 is provided at the end of the mounting portion 31, and the third sealing ring 42 is used to achieve sealing between the mounting portion 31 and the bottom of the mounting groove 12. Optionally, the third sealing ring 42 has a first sealing portion and a second sealing portion, the first sealing portion is sleeved on the outer side of the mounting portion 31 and abuts against the groove wall of the mounting groove 12, the second sealing portion is connected to the first sealing portion, and the second sealing portion is located between the end of the mounting portion 31 and the bottom of the mounting groove 12.

[0027] Reference Figure 5 , Figure 6 According to some embodiments of the present invention, an annular guide groove 13 is provided on the inner wall of the through hole 11, and the groove diameter of the guide groove 13 decreases along the axial direction of the through hole 11 and from the end close to the connecting seat 1 to the end away from the connecting seat 1. The first end of the clamping portion 41 is connected to the mounting seat 3, and the second end of the clamping portion 41 has a guide surface that cooperates with the groove wall of the guide groove 13.

[0028] In some specific examples, there are multiple clamping parts 41, and the multiple clamping parts 41 are arranged around the cable, there is a gap between two adjacent clamping parts 41, the groove wall of the guide groove 13 is conical, and the end of the clamping part 41 close to the guide groove 13 is formed with a guide surface that matches the groove wall of the guide groove 13, the outer wall of the clamping part 41 matches the guide groove 13, and the inner wall of the clamping part 41 fits the surface of the cable. In the process of driving the clamping part 41 to extend into the guide groove 13, as the groove diameter of the guide groove 13 gradually decreases, the groove wall of the guide groove 13 squeezes the movable ends of the multiple clamping parts 41, so that the movable ends of the multiple clamping parts 41 are close to the surface of the cable and clamp the surface of the cable, thereby improving the connection tightness between the mounting seat 3 and the cable. After the clamping part 41 is fully extended into the guide groove 13, the end of the clamping part 41 away from the mounting seat 3 abuts against the end of the first sealing ring 2.

[0029] If a mounting portion 31 is provided at the end of the mounting seat 3, a receiving cavity is formed at the end of the mounting portion 31 facing away from the mounting seat 3, which is convenient for connecting one end of the clamping portion 41 to the mounting seat 3, and there is a movable gap between the outer wall of the clamping portion 41 and the inner wall of the receiving cavity, and the end of the clamping portion 41 with a guide surface extends out of the receiving cavity, which is convenient for cooperating with the guide groove 13.

[0030] Reference Figure 1-Figure 3According to some embodiments of the present invention, the driving member 5 includes: a support frame 51, a movable seat 52, an articulated seat 53, a first connecting rod 54, a second connecting rod 55, and a driving unit 56. The support frame 51 is connected to the connecting seat 1 and is located on one side of the connecting seat 1. The support frame 51 extends horizontally along the length direction of the connecting seat 1, that is, the support frame 51 is located on one side of the connecting seat 1, and the support frame 51 can be spaced apart from the connecting seat 1. The length direction of the support frame 51 is parallel to the length direction of the connecting seat 1. The movable seat 52 is arranged on the support frame 51 and can slide along the length direction of the support frame 51. The mounting seat 3 is located on one side of the movable seat 52 close to the connecting seat 1 and abuts against the movable seat 52. The articulated seat 53 is arranged on the support frame 51. One end of the first connecting rod 54 is hinged to the articulated seat 53, one end of the second connecting rod 55 is hinged to the other end of the first connecting rod 54, and the other end of the second connecting rod 55 is hinged to the movable seat 52. The driving unit 56 is connected to the first connecting rod 54 for driving the first connecting rod 54 to rotate relative to the articulated seat 53. When the driving part 56 drives the first connecting rod 54 to rotate relative to the hinge seat 53 toward the connection seat 1, the hinge axis of the first connecting rod 54 and the second connecting rod 55 moves toward the connection seat 1, and the second connecting rod 55 pushes the movable seat 52 to slide along the support frame 51 toward the connection seat 1, thereby pushing the mounting seat 3 to be inserted into the connection seat 1. On the contrary, when the driving part 56 drives the first connecting rod 54 to rotate relative to the hinge seat 53 away from the connection seat 1, the hinge axis of the first connecting rod 54 and the second connecting rod 55 moves away from the connection seat 1, thereby pulling the movable seat 52 hinged with the second connecting rod 55 away from the connection seat 1 along the support frame 51, thereby disconnecting the mounting seat 3 from the connection seat 1.

[0031] In some specific examples, the support frame 51 includes two support rods, and the two support rods are arranged along the length direction of the connection seat 1, the two support rods are located below the connection seat 1, and the two support rods are respectively located on both sides of the width direction of the connection seat 1, and are located on the outside of the width direction of the connection seat 1, that is, the upper end faces of the two support rods are spaced from the lower end face of the connection seat 1, and the end faces of the two support rods facing each other are respectively spaced from the two side walls in the width direction of the connection seat 1. The length of the support rod is greater than the length of the connection seat 1, so that the driving member 5 can be installed on the support rod and located at one end of the connection seat 1.

[0032] A fixing seat 14 is provided at one end of the connecting seat 1. The outer diameter of the fixing seat 14 is larger than the outer diameter of the connecting seat 1. The connecting seat 1 is fixed to a building, equipment or other obstacle through the fixing seat 14. One end of the support rod is fixed to the end face of the fixing seat 14, and the other end of the support rod extends in a direction parallel to the length direction of the connecting seat 1.

[0033] The movable seat 52 is plate-shaped, and the lower end surface of the movable seat 52 is mounted on the upper end surfaces of the two support rods. A notch is formed on the lower end surface of the movable seat 52 and at a position in the middle, so as not to affect the installation of the cable. Two hinged seats 53 are provided, and the two hinged seats 53 are respectively fixed to the upper end surfaces of the two support rods and close to the end of the support rod away from the connecting seat 1. Each hinged seat 53 is rotatably connected to a drive shaft, and the facing ends of the two drive shafts are spaced apart to provide a clearance space for the cable movement, and the axes of the two drive shafts are located on the same straight line. Two horizontally extending fixed rods are fixed to the end surface of the movable seat 52 away from the connecting seat 1, and the two fixed rods are respectively located above the two support rods and arranged opposite to the support rods. Two first connecting rods 54 and two second connecting rods 55 are provided, and each first connecting rod 54 is connected to a corresponding drive shaft. One end of the first connecting rod 54 is connected to the end of the driving shaft, the other end of the first connecting rod 54 is hinged to one end of the second connecting rod 55, and the other end of the second connecting rod 55 is hinged to the end of the fixed rod away from the movable seat 52. The length of the first connecting rod 54 can be less than the length of the second connecting rod 55. The driving part 56 includes a first rod, a second rod and a holding rod. The first rod and the second rod are both L-shaped. The short rod end of the first rod is fixed to the end of one first connecting rod 54 away from the driving shaft, the short rod end of the second rod is fixed to the end of another first connecting rod 54 away from the driving shaft, and the two ends of the holding rod are respectively fixed to the long rod end of the first rod and the long rod end of the second rod. Specifically, the inner side walls of the L-shaped first rod and the second rod are used as reference surfaces, that is, the side where the first rod and the second rod have a right angle is the inner side wall of the first rod or the second rod. When the movable seat 52 is away from the connection seat 1, the inner side walls of the first rod and the second rod face upward, at which time the short rod of the first rod forms an obtuse angle with the upper surface of the first rod connected thereto, and the short rod of the second rod forms an obtuse angle with the upper surface of the first connecting rod 54 connected thereto, and the driving part 56 is located on the side of the hinged seat 53 away from the connection seat 1, and the first connecting rod 54 and the second connecting rod 55 are both inclined from bottom to top toward the side away from the connection seat 1, and the angle between the first connecting rod 54 and the support frame 51 is smaller than the angle between the second connecting rod 55 and the support frame 51. When the movable seat 52 is close to the connection seat 1, the inner side walls of the first rod and the second rod face downward, and the driving part 56 is located on the side of the hinged seat 53 close to the connection seat 1, and the first connecting rod 54 is inclined from bottom to top toward the side close to the connection seat 1, and the second connecting rod 55 is inclined from bottom to top toward the side away from the connection seat 1.

[0034] By holding the holding rod, the driving part 56 moves toward the side close to the connecting seat 1, driving the driving shaft to rotate, and then driving the first connecting rod 54 to rotate in the direction close to the connecting seat 1, and then driving the hinge axis of the first connecting rod 54 and the second connecting rod 55 to approach one side of the connecting seat 1, so that the second connecting rod 55 pushes the fixed rod, and then pushes the movable seat 52 to approach the connecting seat 1. The working process of driving the movable seat 52 away from the connecting seat 1 by the driving part 56 is the opposite, which will not be repeated here.

[0035] In order to improve the positioning of the driving part 56, a hook 521 is provided on one side of the movable seat 52. After the driving part 56 is rotated toward the side close to the connecting seat 1, the holding rod has a hanging rod that cooperates with the hook 521. The hanging rod is snap-fitted with the hook 521, which is beneficial to positioning the holding rod, thereby ensuring that the mounting seat 3 maintains the reliability of connection with the connecting seat 1.

[0036] Reference Figure 1-Figure 3 According to some embodiments of the present invention, the support frame 51 is provided with an avoidance opening 511 for the mounting seat 3 to pass through, and a stopper 522 is provided above the movable seat 52, and the stopper 522 abuts against the mounting seat 3.

[0037] Exemplarily, specifically, the support frame 51 is composed of two support rods arranged at an interval, and the interval between the two support rods forms the avoidance opening 511 for the mounting seat 3 to pass through in the vertical direction and cooperate with the movable seat 52 .

[0038] The cross section of the mounting seat 3 is rectangular, and the stopper 522 is a structure with an L-shaped cross section, which can be fitted with the connection between the two side walls of the mounting seat 3. The surface of the mounting seat 3 can be provided with an iron sheet, and the side wall where the stopper 522 and the mounting seat 3 fit is provided with a magnet. Therefore, after the mounting seat 3 is inserted into the position aligned with the connecting seat 1 through the avoidance opening 511, the stopper 522 can be magnetically adsorbed with the mounting seat 3 to prevent the mounting seat 3 from falling from the avoidance opening 511. In another example, the width of the avoidance opening 511 is slightly smaller than the width of the mounting seat 3, and the two support rods have elastic deformation ability, so that when the mounting seat 3 passes through the avoidance opening 511, the two support rods can be slightly deformed to allow the mounting seat 3 to pass through. After the mounting seat 3 is located at a position aligned with the through hole 11 of the connecting seat 1, the stopper 522 can be used to position the mounting seat 3, and the two support rods return to their own shapes to prevent the mounting seat 3 from falling downward under their own gravity.

[0039] When the distance between the movable seat 52 and the connecting seat 1 is the largest, the distance is greater than the length of the mounting seat 3 , and the length direction of the mounting seat 3 is parallel to the axial direction of the through hole 11 .

[0040] Reference Figure 5-Figure 6 According to some embodiments of the present invention, a first sealing groove 15 is provided on the inner wall of the through hole 11 , the first sealing groove 15 is connected to the guide groove 13 , and an end of the clamping portion 41 abuts against an end of the first sealing ring 2 .

[0041] Thus, after the mounting seat 3 is fully inserted into the connecting seat 1, the clamping surface of the clamping portion 41 is clamped tightly against the surface of the cable, and the end of the clamping portion 41 away from the mounting seat 3 passes through the guide groove 13 and abuts against the end of the first sealing ring 2, so that the first sealing ring 2 and the clamping portion 41 are in a sealed fit, further improving the overall sealing effect. The first sealing groove 15 is located on the side of the guide groove 13 away from the movable seat 52.

[0042] Reference Figure 1-Figure 3 According to some embodiments of the present invention, a connecting frame is provided on the upper surface of the connecting seat 1, and the connecting frame is close to the end of the connecting seat 1. The connecting frame is hinged with a sealing cover 7, and the sealing cover 7 is connected to the connecting frame through a torsion spring. The sealing cover 7 extends to one side to achieve sealing of the through hole 11. When the cable is connected using this structure, the through hole 11 can be opened by flipping the sealing cover 7. After the mounting seat 3 and the connecting seat 1 are matched, the sealing cover 7 is at least partially pressed on the mounting seat 3 under the action of the torsion spring, which can improve the installation stability of the mounting seat 3.

[0043] In some examples, the sealing cover 7 has a sealing surface and a plurality of mating surfaces, the sealing surface is a rectangular surface mating with the end surface of the connecting seat 1, and the mating surface is a triangular cross section, so that the sealing cover 7 forms a pyramidal structure. When in use, the sealing cover 7 can be turned upward and the mating surface of the sealing cover 7 is abutted against the mounting seat 3, so that the sealing cover 7 can be squeezed in the process of pushing the mounting seat 3 into the connecting seat 1. After the mounting portion 31 is fully inserted into the mounting seat 3, the sealing cover 7 abuts against the surface of the mounting seat 3 outside the connecting seat 1, thereby forming a pressing and fixing effect on the mounting seat 3.

[0044] In addition, when there is no need to install cables and there is no obstacle at the end of the connecting seat 1, the sealing cover 7 is flipped downward by the torsion spring and covers the end of the connecting seat 1. By pulling the driving part 56, the movable seat 52 can be moved closer to the connecting seat 1, and the stopper 522 can be pressed against the connection between the sealing cover 7 and the connecting seat 1. By providing the stopper 522, at least a part of the inner wall of the stopper 522 abuts against the outer wall of the sealing cover 7 and the connecting seat 1, thereby improving the sealing performance of the sealing cover 7 and the connecting seat 1.

[0045] On the other hand, refer to Figure 1-Figure 6 The present invention also proposes a method for assembling a high-voltage via connector, which is used to assemble the high-voltage via connector of any one of the above embodiments, and the method includes the following steps.

[0046] First, install the connection base 1 and ensure that the through hole 11 is coaxially arranged with the through hole. By fixing the fixed base 14 of the connection base 1 to the surface of the corresponding building, equipment or other obstacles with the through hole, specifically, if the through hole 11 is consistent with the through hole diameter, a positioning rod with the same diameter as the through hole 11 can be inserted into the through hole 11 and passed through the through hole to position the connection base 1, and then the fixed base 14 is fixed to the corresponding position by bolts. If the through hole 11 is inconsistent with the through hole diameter, a positioning rod with a diameter corresponding to the smaller diameter of the through hole 11 or the through hole is selected, and a positioning sleeve is set on the positioning rod. The positioning sleeve matches the larger diameter of the through hole 11 or the through hole, so as to facilitate the installation and positioning of the connection base 1. The support frame 51, the movable seat 52, and the connection between the movable seat 52 and the support frame 51 are all pre-fixed to the connection base 1.

[0047] The mounting seat 3 is sleeved outside the cable so that the mounting seat 3 and the cable are in a sealed fit. Specifically, the mounting seat 3 can be set at the corresponding position of the cable by predetermining the length of the cable that needs to be passed through, or the mounting seat 3 can be set at a position close to one end of the cable. After the mounting seat 3 is connected to the movable seat 52, the resistance of the first sealing ring 2 and the second sealing ring 6 is overcome by pulling the cable to change the relative position of the mounting seat 3 and the cable. Finally, the cable can be reinforced by the clamping portion 41.

[0048] The mounting seat 3 connected to the cable is mounted to one side of the movable seat 52 and located between the movable seat 52 and the connecting seat 1, so that the mounting seat 3 abuts against the side of the movable seat 52 close to the connecting seat 1, and then one end of the cable is inserted into the through hole 11, and the mounting seat 3 is driven by the driving member 5 to move toward the connecting seat 1, so that the sealing connector 4 is inserted into the through hole 11, and the first sealing ring 2 is sleeved outside the cable to seal with the cable, and the sealing connector 4 abuts against the end of the first sealing ring 2. Specifically, a guide can be set at the end of the cable that needs to pass through the through hole, and a hook 521 connector that cooperates with the guide can be set on the other side of the through hole, so that the end of the cable can be smoothly guided through the through hole.
