[0023] The technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] Specific implementation method 1: Figure 1-10 As shown, this embodiment describes a power cable connector for power signal transmission, including an insulating shell 1 and two rotating devices 2; the insulating shell 1 is cylindrical, and a connecting plate 14 is fixedly connected to the inner center of the insulating shell 1, and an annular groove 12 is provided in the middle position of the outer circumferential surface of the insulating shell 1; two through-holes 13 are symmetrically provided on the inner wall of the annular groove 12, and the through-holes 13 are respectively located on both sides of the connecting plate 14; a plurality of through-holes 15 are provided on the inner wall of the insulating shell 1 at positions opposite to the corresponding through-holes 13, and a slide 16 is provided in each of the through-holes 15 to slide with it; a plurality of arc-shaped grooves 17 are provided on the side surface of each of the through-holes 13, and the other end of the arc-shaped groove 17 is connected to the corresponding through-hole 15; a limiting groove 18 is provided on the inner wall of the arc-shaped groove 17, one end of which is connected to the through-hole 13, and the other end of the limiting groove 18 is connected to the transverse groove 19; the transverse groove 19 is connected to the corresponding through-hole 15;

[0025] The rotating device 2 includes a rotating ring 21, which fits over the annular groove 12. The inner wall of the rotating ring 21 is provided with multiple grooves 23, each with a slideway 22 on either side. A push block 26 is positioned within the groove 23, which slidably engages therewith. A fixed block 25 is positioned on the side of the push block 26, which slidably engages with the slideway 22. A spring 24 is provided between the push block 26 and the inner wall of the groove 23. The push block 26 slidably engages with the arcuate groove 17 and the through hole 15. The fixed block 25 slidably engages with the limit groove 18 and the transverse groove 19. The position of the slide 16 and the insert block 26 is used to determine whether the power cable is fully inserted and in contact with the connecting plate 14.

[0026] The slide 16 has a triangular notch 110 on one side facing the transverse groove 19, and a push rod 28 is provided on the other side of the push block 26 to slide with the notch 110. As the rotating ring 21 rotates, the push rod 28 drives the slide 16 to clamp the power cable.

[0027] The sliding plate 16 is provided with an inclined surface at one end located inside the housing 11 and away from the connecting plate 14 .

[0028] When the slide plate 16 completely enters the through hole 15 , the push block 26 is separated from the through hole 15 .

[0029] When the push block 26 moves to the inside of the through hole 13 along with the rotating ring 21 , the fixing block 25 is separated from the slideway 22 under the elastic force of the spring 24 , and the push block 26 remains in the groove 23 .

[0030] The rotation directions of the rotating rings 21 on the two rotating devices 2 are opposite, and the arc-shaped grooves 17 on both sides of the connecting plate 14 are arranged in a centrally symmetrical manner.

[0031] It also includes a limiting device 3; the limiting device 3 includes a circular ring 31; the circular ring 31 is connected to the annular groove 12 through a bearing, and an arc-shaped sliding groove 32 is provided on the circular ring 31 and passes through the circular ring 31; a bidirectional elastic telescopic rod 33 is provided in the sliding groove 32 and slides with it; the two free ends of the bidirectional elastic telescopic rod 33 abut against the side surfaces of the corresponding rotating ring 21.

[0032] The two rotating rings 21 have circular holes 27 on their opposing surfaces, and the free ends of the bidirectional elastic telescopic rods 33 slidably engage with the corresponding circular holes 27. The rotating rings 21 rotate in opposite directions, and the bidirectional elastic telescopic rods 33 restrain the two rotating rings 21 after installation to prevent the power cables from becoming loose.

[0033] The plurality of slides 16 on each side of the connecting plate 14 are arranged along the setting direction of the center line of the housing 11 , and the slide 16 closest to the connecting plate 14 is in contact with the side surface of the connecting plate 14 .

[0034] A method for using a power cable connector for power signal transmission, the method comprising the following steps:

[0035] Step 1: Insert the power cable into the insulating housing 1. When the power cable contacts the connecting plate 14, rotate the rotating ring 21.

[0036] Step 2: Rotate the rotating ring 21 to move the slide plate 16 upward and squeeze the power cable to increase the friction between the two and prevent the power cable from slipping;

[0037] Step 3: After all the power cables on both sides of the connecting plate 14 are installed, rotate the ring 31 to insert the free ends on both sides of the bidirectional elastic telescopic rod 33 into the corresponding circular holes 27 .

[0038] The working principle of the present invention is as follows: when using the device, the power cable is inserted into the interior of the insulating housing 1. As the power cable is inserted, the power cable contacts the inclined surfaces of the plurality of slides 16 in turn, and pushes the slides 16 and the push blocks 26 in contact therewith to move in a direction away from the center of the housing 11 until the slides 16 are completely moved into the corresponding through-holes 15. At this time, the push blocks 26 compress the corresponding springs 24 and disengage from the through-holes 15. The power cable pushes the slide 16 closest to the connecting plate 14 to completely move into the corresponding through-holes 15, and the power cable is fully connected to the connecting plate 14. The rotating ring 21 can then be rotated. If the power cable is not fully in contact with the connecting plate 14, the slide plate 16 cannot be fully moved into the corresponding through hole 15, and the slide plate 16 cannot push the push block 26 out of the through hole 15, resulting in a portion of the push block 26 being located in the through hole 15 and the other portion being located in the groove 23, thereby causing the rotating ring 21 to be unable to rotate relative to the housing 11, making it easier for staff to determine whether the power cable is in full contact with the connecting plate 14, thereby effectively avoiding virtual connection or disconnection between the power cable and the connecting plate 14 after installation, which affects power or signal transmission;

[0039] After the power cable is fully in contact with the connecting plate 14, the rotating ring 21 is rotated. Since the push block 26 is completely out of the through hole 15, the push block 26 no longer restricts the rotation of the rotating ring 21. During the rotation of the rotating ring 21, the push block 26 is first driven to rotate toward the side where the arc groove 17 is not provided, so that the push block 26 slides on the inner wall of the annular groove 12 until the push block 26 moves to the position of the through hole 13. Under the elastic force of the spring 24, the push block 26 partially moves into the through hole 13, and at the same time, the push block 26 drives the fixed block 25 to move into the through hole 13. As the rotating ring 21 continues to rotate, the push block 26 moves into the arc groove 17, and the fixed block 25 slides with the limiting groove 18 on the inner wall of the arc groove 17, and the rotating ring 21 continues to rotate. After the fixed block 25 rotates to the other end of the limiting groove 18, it then slides into the transverse groove 19. After the rotating ring 21 continues to rotate, the fixed block 25 and the push block 26 move along the setting direction of the transverse groove 19, and drive the push rod 28 to move together until the push rod 28 enters the notch 110. The rotating ring 21 rotates to make the push rod 28 contact the inclined surface of the notch 110, and pushes the slide plate 16 to move in the direction of the central axis of the housing 11 through the inclined surface, thereby clamping the power cable through the slide plate 16 and the inner wall of the housing 11 to prevent it from loosening;

[0040] After the power cable on the other side of the housing 11 is installed and fixed according to the above steps, the center lines of the circular holes 27 on the opposite surfaces of the two rotating rings 21 coincide with each other, and then the bidirectional elastic telescopic rod 33 is pulled, and the bidirectional elastic telescopic rod 33 moves upward until the two free ends of the bidirectional elastic telescopic rod 33 are respectively inserted into the corresponding circular holes 27; since the two rotating rings 21 rotate in opposite directions during the process of clamping the power cable, after the double-line elastic telescopic rod 33 is inserted into the corresponding circular holes 27, the two rotating rings 21 can only rotate in the same direction. When one of the rotating rings 21 is rotated in the direction that causes the power cable to loosen due to external force, the other rotating ring 21 is driven by the bidirectional elastic telescopic rod 33 to rotate in the direction that causes the power cable to be clamped. Since the power cable has been clamped during the installation process, the rotating ring 21 cannot rotate in the direction that the power cable is clamped, and the rotating ring 21 under external force cannot rotate in the direction that the power cable is loosened. The two rotating rings 21 restrain each other to prevent the power cable from loosening.

[0041] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other configurations without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations coming within the meaning and range of equivalents of the claims are intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0042] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
