DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments 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 part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] A communication cable connector, such as Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, it includes an upper semicircular tube 1 and a lower semicircular tube 2, and the upper semicircular tube 1 and the lower semicircular tube 2 form a horizontal tube. The upper semicircular tube 1 and the lower semicircular tube 2 are symmetrically distributed up and down. Three coaxial annular dovetail grooves 3 are provided on the inner circumference of the horizontal tube. Two semicircular dovetail sliders 4 are slidably installed in the annular dovetail grooves 3 respectively. Half of the annular dovetail groove 3 is located on the upper semicircular tube 1, and the other half is located on the lower semicircular tube 2. Two dovetail sliders 4 in the same annular dovetail groove 3 can form a dovetail slider ring. The dovetail slider ring is coaxially arranged with the annular dovetail groove 3. Two dovetail sliders 4 that form the dovetail slider ring, one is located in the annular dovetail groove 3 of the upper semicircular tube 1, and the other is located in the annular dovetail groove 3 of the lower semicircular tube 2. Semicircular rings 5 ​​are fixedly installed on the inner sides of the dovetail sliders 4 respectively, and the two semicircular rings 5 ​​corresponding to the upper and lower sides can form a ring. It is characterized in that the dovetail sliders 4 on both sides can The angle range that can rotate in the corresponding annular dovetail groove 3 is 10°-170°. In this embodiment, the dovetail sliders 4 on both sides can rotate 18° in the corresponding annular dovetail groove 3. The angle of rotation of the dovetail sliders 4 on both sides in the corresponding annular dovetail groove 3 is too large or too small. The position where the dovetail slider 4 slides from the upper semicircular tube 1 into the lower semicircular tube 2 is too small. The connection strength between the upper semicircular tube 1 and the lower semicircular tube 2 is low. The middle dovetail slider 4 can rotate continuously in the corresponding annular dovetail groove 3. The upper semicircular tube 1 is provided with an adjustment device that can adjust the angle of the middle dovetail slider 4 in the corresponding annular dovetail groove 3. The two adjacent circular rings are connected by several fastening ropes 6. The fastening ropes 6 are evenly distributed along the axis of the circular ring. The length of the fastening rope 6 is 1.5 to 3 times the distance between the two circular rings. In this embodiment, the length of the fastening rope 6 is 2 times the distance between the two circular rings. The present invention has a simple structure and an ingenious design. An upper semicircular tube 1 and a lower semicircular tube 2 are used to form a protective shell on the outside of a cable connector. The upper semicircular tube 1 and the lower semicircular tube 2 can be quickly connected and are beneficial to forming a self-locking force on the cable. After the cable is tightened, the upper semicircular tube 1 and the lower semicircular tube 2 cannot be opened. At the same time, a tightening rope 6 is used to wrap around and tighten the cable. The tightening rope 6 can better fit the cable and is suitable for fixing cables of different diameters. It can also form a pre-tightening tension in opposite directions at the cable connector to keep the cable connector well connected. At the same time, the pre-tightening tension is used to buffer the external tension on the cable and reduce damage to the cable.When using the present invention, first separate the upper semicircular tube 1 and the lower semicircular tube 2, and place the dovetail slider 4 and the semicircular ring 5 on the corresponding upper semicircular tube 1 and the lower semicircular tube 2. Place the lower semicircular tube 2 below the cable connector, and align the middle semicircular ring 5 with the middle of the cable connector. The cable connector is placed in the middle semicircular ring 5, and the cables on the cable connector are located in the semicircular rings 5 ​​on both sides. Then, buckle the upper semicircular tube 1 on the lower semicircular tube 2, and the upper semicircular tube 1 and the lower semicircular tube 2 form a horizontal tube. The cable connector is located between the circular ring and the fastening rope 6 in the horizontal tube. At this time, adjust the middle dovetail slider 4 through the adjusting device, and the dovetail slider 4 is in the middle annular dovetail groove 3 The dovetail slider 4 rotates forwardly, driving the middle semicircular ring 5 to rotate, and the tightening rope 6 is gradually tightened from a relaxed state. The middle semicircular ring 5 drives the semicircular rings 5 ​​and the dovetail slider 4 on both sides to rotate forwardly through the tightening rope 6. Since the dovetail sliders 4 on both sides can only rotate 18° in the corresponding annular dovetail grooves 3, at this time, the dovetail slider 4 in the annular dovetail groove 3 on the upper semicircular tube 1 enters the annular dovetail groove 3 on the lower semicircular tube 2, and the dovetail slider 4 in the annular dovetail groove 3 on the lower semicircular tube 2 enters the annular dovetail groove 3 on the upper semicircular tube 1. The upper semicircular tube 1 and the lower semicircular tube 2 are connected by the cooperation of the dovetail slider 4 and the annular dovetail groove 3. Together, continue to adjust the middle dovetail slider 4 to rotate through the adjustment device, the semicircular ring 5 connected to the outer end of the fastening rope 6 no longer rotates, and the middle semicircular ring 5 drives the inner end of the fastening rope 6 to continue to rotate forward, and the middle of several fastening ropes 6 evenly distributed in a circle begins to gather inward, and the fastening rope 6 begins to be wound around the cables on both sides of the cable connector. Several fastening ropes 6 are evenly spirally wound around the outer circumference of the cable to form a uniform tension, so that the cable connector and the cable are located in the middle of the cross tube, reducing the contact between the cable connector and the cable and the cross tube, and facilitating the heat at the cable connector to dissipate through the gap between the cable connector, the cable and the cross tube; the fastening rope 6 is in the process of being wound around the cable In the process, the middle part of the fastening rope 6 first fits with the cable, and as the middle semicircular ring 5 continues to rotate forward, the inner end of the fastening rope 6 continues to be wrapped around the outer circumference of the cable and fits tightly with the cable, and at the same time, the inner end of the fastening rope 6 is pulled toward the middle semicircular ring 5, and the fastening rope 6 drives the cable to move toward the cable connector, so that the cable connector maintains a good connection; when the fastening rope 6 drives the cable to move toward the cable connector, a buffer margin is formed. When the cables on both sides of the cable connector are subjected to external tension, the cables move outside the cross tube to offset the buffer margin, thereby reducing the risk of disconnection of the cable connector; the use of a flexible fastening rope 6 can better fit the cable and is suitable for fixing cables of different diameters.

[0018] Specifically, if Figure 1 and Figure 2As shown, the adjustment device described in this embodiment includes a worm 20, a groove 21 is provided on one side of the middle annular dovetail slide 3, the worm 20 is located in the groove 21, and worm gear grooves 23 are provided on the outer periphery of the middle dovetail slider 4, the worm gear grooves 23 on the two dovetail sliders 4 are continuously distributed, and the worm 20 can be continuously meshed with the worm gear grooves 23 on the two dovetail sliders 4, the worm 20 and the groove 21 are located on the upper semicircular tube 1, the groove 21 is connected to the outside through the through hole 22, the worm 20 is rotatably installed in the through hole 22 through a bearing, and one end of the worm 20 extends out of the upper semicircular tube 1. When the worm 20 is turned, the worm 20 drives the middle dovetail slider 4 to rotate in the annular dovetail slide 3 through the worm gear groove 23, and the self-locking between the worm and the worm is used to lock the position of the dovetail slider 4 in the annular dovetail slide 3, thereby realizing the angle adjustment of the middle dovetail slider 4.

The outer circumference of the connecting shaft 30 is respectively movably sleeved with a sleeve 31, and the sleeve 31 is fixed on the lower semicircular tube 2. The connecting shaft 30 and the sleeve 31 are coaxially arranged. When the upper semicircular tube 1 and the lower semicircular tube 2 are opened, the upper semicircular tube 1 is moved to the left relative to the lower semicircular tube 2, and the connecting shaft 30 is pulled out from the sleeve 31, so that the upper semicircular tube 1 and the lower semicircular tube 2 are separated; the upper semicircular tube 1 and the lower semicircular tube 2 are hinged, and when the upper semicircular tube 1 and the lower semicircular tube 2 are closed, they rotate along the axis of the connecting shaft 30, so that the upper semicircular tube 1 and the lower semicircular tube 2 are closed more labor-saving.

[0020] Further, such as Figure 3 As shown, the dovetail sliders 4 at both ends of the transverse tube described in this embodiment are fixedly installed with a slide bar 40 on one side, and a strip slide groove 41 is provided on the side of the annular dovetail slot 3 corresponding to the slide bar 40.

When the dovetail sliders 4 at both ends of the transverse tube rotate in the annular dovetail slot 3, the dovetail sliders 4 drive the slide bar 40 to slide in the strip slide groove 41, and the slide bar 40 moves from one end of the strip slide groove 41 to the other end, and the dovetail slider 4 can no longer drive the slide bar 40 to rotate, thereby limiting the rotation angle of the dovetail slider 4 in the annular dovetail slot 3, and preventing the dovetail sliders 4 at both ends of the transverse tube from rotating infinitely in the annular dovetail slot 3.

[0021] Furthermore, if Figure 2As shown, the upper semicircular tube 1 of this embodiment is provided with a plurality of limit grooves 50, and an insert block 51 is inserted and matched in the limit groove 50, and the insert block 51 is fixed on the lower semicircular tube 2. When the insert block 51 is located in the limit groove 50, the annular dovetail groove 3 on the upper semicircular tube 1 and the annular dovetail groove 3 on the lower semicircular tube 2 are aligned, and at this time, the dovetail slider 4 can slide from the annular dovetail groove 3 on the upper semicircular tube 1 into the annular dovetail groove 3 on the lower semicircular tube 2, and the dovetail slider 4 can also slide from the annular dovetail groove 3 on the lower semicircular tube 2 into the annular dovetail groove 3 on the upper semicircular tube 1.

When the fastening ropes 6 begin to be wound around the cable, the tension springs 61 are not stretched, and the distance between the small semicircular rings 60 and the semicircular rings 5 ​​is the smallest. After the fastening ropes 6 are wound around the outer circumference of the cable, when the fastening ropes 6 pull the cable to move toward the cable connector, the outer ends of the fastening ropes 6 are provided to pull the small semicircular rings 60 toward the middle semicircular rings 5, and the tension springs 61 are stretched, providing a movement margin for the fastening ropes 6 to pull the cable toward the middle semicircular rings 5.

[0023] Furthermore, Figure 1 As shown, the semicircular rings 5 ​​at both ends of the transverse tube in this embodiment are provided with a plurality of insertion holes 70, and a plug rod 71 is slidably arranged in the insertion hole 70, and the plug rod 71 is fixed on the small semicircular ring 60, and the tension spring 61 is sleeved on the outer circumference of the plug rod 71. When the small semicircular ring 60 moves left and right relative to the semicircular ring 5, the plug rod 71 slides in the corresponding insertion hole 70, and the plug rod 71 plays a guiding role to prevent the small semicircular ring 60 from tilting.

[0024] Furthermore, Figure 1 As shown, the outer ends of the plug rods 71 ​​of this embodiment are respectively fixed with baffles 80. The baffles 80 cannot enter the plug hole 70, thereby preventing the plug rods 71 ​​from being pulled out of the plug hole 70.
