[0039] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0040] Embodiment 1:

[0041] See also Figures 1 to 7 An angle-adjustable high-voltage connector includes a sleeve 1 with a shoulder at the end, a wire tightening device 2 is arranged inside the sleeve 1, a mounting ring 3 is slidingly sleeved on the outer wall of the sleeve 1 near the shoulder, an annular guide rail 31 is arranged on the upper end face of the mounting ring 3, and an arc plate 4 is evenly arranged on the lower end face of the mounting ring 3 along its circumference, and the lower end of the arc plate 4 is fixedly connected to the outer wall of the sleeve 1.

[0042] An annular groove is provided on the end face of the sleeve 1 away from the wire tightening device 2, and a wire reservation component 11 is slidably installed in the annular groove. The wire reservation component 11 includes a support plate 111, and a support plate 111 is slidably arranged in the annular guide rail 31 near the high-voltage connector 7. A return frame 112 is fixedly connected to the upper end of the support plate 111, and redirecting rods 113 are symmetrically installed near the two ends of the return frame 112. A rectangular groove 115 is provided on the inner wall of the return frame 112 between the redirecting rods 113, and a pre-tensioning rod 114 is slidably installed in the rectangular groove 115 through a compression spring 116.

[0043] The wire tightening device 2 includes a connecting rod 21, which is symmetrically installed on the inner wall of the sleeve 1, and a tightening ball 22 is fixedly connected to the proximal end of the connecting rod 21. A through groove 23 is opened in the middle of the tightening ball 22, and a slide groove 24 is symmetrically opened on the inner side wall of the middle of the through groove 23. A first wedge block 26 is slidably installed in the slide groove 24 through a connecting spring 25, and a tightening wheel 27 is fixedly installed at the end of the first wedge block 26 away from the connecting spring 25. An annular internal thread groove 28 is opened above the slide groove 24, and an external threaded tube 29 is threaded in the annular internal thread groove 28. The lower end of the external threaded tube 29 is in contact with the inclined surface of the first wedge block 26, and a plurality of rubber teeth are arranged on the arc-shaped side walls proximal to the two tightening wheels 27.

[0044] The arc plate 4 is made of elastic material and its concave arc surface faces away from the sleeve 1 .

[0045] During the specific operation, the electric wire of the high-voltage connector 7 is first manually passed upward from the bottom of the sleeve 1, so that it first passes through the through slot 23 in sequence, and then passes out from above the left redirection rod 113, below the pre-tightening rod 114, and above the right redirection rod 113, and finally the end thereof is fixed on the pin of the high-voltage connector 7, so that the high-voltage connector 7 can be powered on and operated. At this time, the gravity of the pre-tightening rod 114 will drive the compression spring 116 to stretch, and at the same time, the pre-tightening rod 114 will cause the electric wire to be arranged in a curved form in the circular frame 112;

[0046] By manually rotating the external thread tube 29, the external thread tube 29 moves downward while rotating at this time and presses the inclined surface of the first wedge block 26, thereby driving the first wedge blocks 26 and the tightening wheels 27 on both sides to approach each other. The connecting spring 25 is stretched. Finally, the rubber teeth provided on the arc-shaped side wall of the tightening wheel 27 can tighten the electric wire bundle without damaging the electric wire, avoiding the vertical movement of the electric wire driven by the high-voltage connector 7 during subsequent use.

[0047] Embodiment 2:

[0048] Basically the same as the technical solution of Embodiment 1, refer to Figures 1 to 3 and Figure 8 and Fig. 9 , the difference is that: a contact device 5 is uniformly arranged along the circumference inside the mounting ring 3, an adjusting device 6 is arranged outside the mounting ring 3, the adjusting device 6 and the contact device 5 are cooperatively connected, and a high-voltage connector 7 is fixedly arranged at the upper end of the adjusting device 6.

[0049] The contact device 5 includes a T-shaped groove 51. The T-shaped groove 51 is uniformly opened along the circumference inside the mounting ring 3. A second wedge block 53 is slidably installed in the horizontal groove of the T-shaped groove 51 through a contact spring 52. A contact protrusion 54 is fixedly arranged at the end of the second wedge block 53 away from the contact spring 52. An extrusion protrusion 55 is slidably installed at the bottom of the vertical groove of the T-shaped groove 51 through a support spring 56. The upper end of the extrusion protrusion 55 abuts against the inclined surface of the second wedge block 53.

[0050] The adjusting device 6 includes a sector plate 61. The sector plate 61 is slidably installed on the side of the mounting ring 3. The sector plate 61 is cooperatively connected with the annular guide rail 31. An installation groove 62 is opened in the middle of the upper end surface of the sector plate 61. An adjusting component 63 is arranged in the installation groove 62. The upper end of the adjusting component 63 is fixedly connected with a high-voltage connector 7. A threaded hole 64 is opened in the lower end surface of the sector plate 61. A threaded ejector rod 65 is screwed in the threaded hole 64. A contact hole 611 is opened on the side wall of the sector plate 61 facing the contact protrusion 54.

[0051] The adjusting component 63 includes a rotating shaft 631. The rotating shaft 631 is rotatably installed on the inner side wall of the installation groove 62. A U-shaped insulating base 632 is fixedly installed on the rotating shaft 631. The opening of the U-shaped insulating base 632 faces downward. An adjusting gear 633 is fixedly arranged in the middle of the rotating shaft 631. A rectangular rack 634 is engaged below the adjusting gear 633. A strip-shaped chute is opened at the bottom of the installation groove 62. Limiting holes 635 are uniformly opened at the bottom of the strip-shaped chute. The rectangular rack 634 is slidably installed in the strip-shaped chute and a pin 636 is inserted at the end of the rectangular rack 634 away from the adjusting gear 633. The lower end of the pin 636 is inserted into the limiting hole 635.

[0052] A through hole is formed at the bottom of the vertical groove of the T-shaped groove 51, and the upper end of the threaded ejector rod 65 passes through the through hole and abuts against the lower end of the extrusion protrusion 55.

[0053] It should be noted that in this embodiment, the abutting spring 52 is in a stretched state at the initial position, and the abutting protrusion 54 abuts in the abutting hole 611, making the adjusting device 6 unable to rotate.

[0054] During specific operation, during the connection process of the high-voltage connector 7, the position of the high-voltage connector 7 can be adjusted as needed. The specific adjustment process is as follows: First, manually rotate the threaded ejector rod 65 forward so that the upper end of the threaded ejector rod 65 disengages from the mounting ring 3. At this time, the reaction force of the abutting spring 52 will drive the second wedge block 53 to move towards the inside of the T-shaped groove 51, so that the abutting protrusion 54 disengages from the abutting hole 611. Then, manually rotate the adjusting device 6 as a whole to change the relative position of the high-voltage connector 7. When the position of the high-voltage connector 7 is determined, rotate the threaded ejector rod 65 in the reverse direction, drive the extrusion protrusion 55 to move upward through the threaded ejector rod 65 and extrude the inclined surface of the second wedge block 53, thereby driving the second wedge block 53 and the abutting protrusion 54 to move towards the abutting hole 611. Finally, the sector plate 61 is limited and fixed through the mutual cooperation of the abutting hole 611 and the abutting protrusion 54. At this time, the high-voltage connector 7 and the plug to be inserted are inserted together, thus achieving the purpose of flexible installation;

[0055] When encountering a narrow installation space, the angle of the high-voltage connector 7 relative to the plug to be inserted can be adjusted in advance. The specific adjustment process is as follows: First, manually pull out the pin 636 upward, and then drive the adjusting gear 633 to rotate by pushing the rectangular rack 634, thereby driving the rotating shaft 631, the U-shaped insulating base 632, and the high-voltage connector 7 as a whole to rotate. When the installation angle of the high-voltage connector 7 is determined, insert the pin 636 into the end of the rectangular rack 634 and fix the rectangular rack 634 using the limiting hole 635 at the corresponding position. Finally, insert the high-voltage connector 7 and the plug to be inserted at the corresponding angle together to quickly complete the installation process.

[0056] The working principle of the present invention during use:

[0057] First: Manually pass the electric wire of the high-voltage connector 7 upward from below the sleeve 1, so that it first passes through the through groove 23 in sequence, then passes above the left deflecting rod 113, below the pre-tightening rod 114, and above the right deflecting rod 113, and finally fix its end on the lead of the high-voltage connector 7, so that the high-voltage connector 7 can operate with electricity. At this time, the gravity of the pre-tightening rod 114 will drive the compression spring 116 to stretch, and at the same time, the pre-tightening rod 114 will make the electric wire arranged in a curved form within the loop frame 112;

[0058] Second: Manually rotate the external thread tube 29. At this time, the external thread tube 29 moves downward while rotating and squeezes the inclined surface of the first wedge block 26, thereby driving the first wedge blocks 26 and the tightening wheels 27 on both sides to approach each other. The connecting spring 25 is stretched. Finally, the rubber teeth provided on the arc-shaped side wall of the tightening wheel 27 can tighten the electric wire bundle without damaging the electric wire, avoiding the vertical movement of the electric wire driven by the high-voltage connector 7 during subsequent use;

[0059] Third: During the connection process of the high-voltage connector 7, the position of the high-voltage connector 7 can be adjusted as needed. The specific adjustment process is as follows: First, manually rotate the threaded ejector rod 65 forward so that the upper end of the threaded ejector rod 65 disengages from the mounting ring 3. At this time, the reaction force of the abutting spring 52 will drive the second wedge block 53 to move into the T-shaped groove 51, so that the abutting protrusion 54 disengages from the abutting hole 611. Then, manually rotate the adjusting device 6 as a whole to change the relative position of the high-voltage connector 7. When the position of the high-voltage connector 7 is determined, rotate the threaded ejector rod 65 in the reverse direction. Drive the pressing protrusion 55 to move upward and press the inclined surface of the second wedge block 53, thereby driving the second wedge block 53 and the abutting protrusion 54 to move towards the abutting hole 611. Finally, the limiting and fixing of the sector plate 61 are realized through the mutual cooperation of the abutting hole 611 and the abutting protrusion 54. At this time, the high-voltage connector 7 and the plug to be inserted are inserted together, so as to achieve the purpose of flexible installation;

[0060] Fourth: When encountering a narrow installation space, the angle of the high-voltage connector 7 relative to the plug to be inserted can be adjusted in advance. The specific adjustment process is as follows: First, manually pull out the pin 636 upward, and then drive the adjusting gear 633 to rotate by pushing the rectangular rack 634, thereby driving the rotating shaft 631, the U-shaped insulating base 632 and the high-voltage connector 7 as a whole to rotate. When the installation angle of the high-voltage connector 7 is determined, insert the pin 636 into the end of the rectangular rack 634 and fix the rectangular rack 634 by using the limiting hole 635 at the corresponding position. Finally, insert the high-voltage connector 7 and the plug to be inserted at the corresponding angle together to quickly complete the installation process;

[0061] Fifth: During the adjustment process of the high-voltage connector 7, the high-voltage connector 7 may exert a certain traction force on the electric wire. This traction force can drive the pre-tightening rod 114 to move up and down, and with the combined use of the compression spring 116, it can prevent the electric wire from falling off from the pins of the high-voltage connector 7, ensuring the stability of the high-voltage connector 7 during use and reducing the possibility of damage to the electric wire due to being pulled off.
