[0011] Preferably, the outer wall of the cable terminal is fixedly connected with a plurality of umbrella skirt protective sleeves, and the end of the cable terminal is sleeved with a branch cable insulation sheath.

[0013] Preferably, the inner wall of the cable terminal is fixedly connected with a stress cone.

[0014] Compared with the prior art, the present application has the following advantages:

[0015] 1、In the present application, the fixed bolts on both sides of the wire pressing end body are rotated, and when the two movable wire clamping cones on both sides are close to each other, the copper wire in the wire pressing end body can be clamped and clamped, and the copper wire is bent and squeezed into the gap between the upper and lower adjacent movable wire clamping cones, so that the copper wire is pressed and fastened between the movable wire clamping cones, and the copper wire needs to overcome the horizontal and vertical friction between the movable wire clamping cones, so that the copper wire will be difficult to fall off, greatly improving the installation and fastening degree of the copper wire.

[0016] 2. In this invention, when the movable clamping frames on both sides move closer to each other, the entire movable clamping frame moves upward, and multiple movable clamping cones move upward with the clamped and deformed copper wire, so that the copper wire is pulled from the end of the cable body, and the copper wire that has been clamped and bent by the movable clamping cones is further tightened in a bent state on the outer wall of the multiple movable clamping cones, which further reduces the probability of the copper wire falling off and increases the tightness of the copper wire installation.

[0017] 3. In this invention, as the two movable clamping frames approach each other, the movable clamping frames on both sides simultaneously deflect clockwise by a certain angle, causing the copper wire clamped inside the movable clamping frame to be bent at a certain angle from the clamping end along the end of the cable body. The bending increases the friction between the outer wall of the clamping end body and the end of the copper wire, further improving the anti-detachment measures for the copper wire. This allows the copper wire to be fastened at different angles at different positions within the clamping end body, enabling all-round fastening of multiple copper wires that are surrounded and closely arranged.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0032] Embodiment one: This embodiment promotes the solution to the problem that when the copper wires are arranged in an inner and outer surrounding manner and are fastened by wire pressing bolts, the copper wires arranged close to the inner surrounding part cannot be pressed, and the copper terminals have a risk of falling off after installation, in the case of more and denser copper wires in the cable. Please refer to Figure 1 Figure 11 A cable accessory with adjusting function, comprising a main cable insulation sheath 1 and a wire pressing end main body 7, two first sliding grooves 10 are formed on the wire pressing end main body 7, a first sliding block 11 is slidably connected to the inner wall of the first sliding groove 10, a fixing bolt 12 is threadedly connected to the inner wall of the first sliding block 11, a first ball 13 is fixedly connected to one end of the fixing bolt 12, a mounting seat 14 is rotatably installed on the outer wall of the first ball 13, a moving wire clamping frame 17 is fixedly connected to the outer wall of the mounting seat 14, and a plurality of uniformly distributed moving wire clamping cones 18 are fixedly connected to the inner wall of the moving wire clamping frame 17.

[0033] ​The outer wall of the mobile clamp wire frame 17 is fixedly connected with a second return spring 19, one end of the second return spring 19 is fixedly connected with a first guide rod 20, the outer wall of the first guide rod 20 is fixedly connected with a second sliding block 21, the inner wall of the wire pressing end head body 7 is fixedly connected with a guide frame 23, the first guide rod 20 is slidingly connected to the inner wall of the guide frame 23, one end of the first guide rod 20 is rotatably installed with a second rolling ball 22, the inner wall of the guide frame 23 is provided with a second sliding groove 24, and the second sliding block 21 is slidingly connected to the inner wall of the second sliding groove 24.

[0034] The inner wall of the first sliding groove 10 is fixedly connected with a first guide rod 15, the outer wall of the first guide rod 15 is sleeved with a first return spring 16, one end of the first return spring 16 is fixedly connected with the inner wall of the first sliding groove 10, and the other end of the first return spring 16 is fixedly connected with the outer wall of the first sliding block 11.

[0035] The outer wall of the mounting seat 14 is fixedly connected with a second guide rod 25, one end of the second guide rod 25 is rotatably connected with a third sliding block 28, the inner wall of the wire pressing end head body 7 is provided with a first track groove 29 and a second track groove 30, the first track groove 29 and the second track groove 30 are in communication with each other, and the third sliding block 28 is slidingly connected to the inner wall of the first track groove 29.

[0036] The outer wall of the main cable insulation sheath 1 is provided with a plurality of wire outlet holes 2, the inner wall of the wire outlet hole 2 is slidingly connected with a cable body 3, and the outer wall of the cable body 3 is sleeved with a cable terminal connector 4.

[0037] The outer wall of the cable terminal connector 4 is fixedly connected with a plurality of umbrella skirt protective sleeves 5, and the end of the cable terminal connector 4 is sleeved with a branch cable insulation sheath 6.

[0038] The wire pressing end head body 7 is slidingly installed on the inner wall of the branch cable insulation sheath 6, and the outer wall of the wire pressing end head body 7 is fixedly connected with a copper wire terminal 8.

[0039] The inner wall of the cable terminal connector 4 is fixedly connected with a stress cone 9.

[0040] In this embodiment: when using the cable accessory with the adjusting function, first, the cable body 3 is inserted into the main cable insulation sheath 1, then the end of the cable body 3 is pulled out from the wire outlet hole 2, and the end of the cable body 3 is inserted into the cable terminal connector 4, and the end is exposed from the branch cable insulation sheath 6, then the end of the cable body 3 is stripped, the length of the stripped wire matches the depth of the inner wall of the wire pressing end head body 7, and then the copper wire that needs to be stripped is inserted into the inner wall of the wire pressing end head body 7.

[0041] Meanwhile, the fixed bolts 12 on both sides of the pressing wire end head body 7 are rotated, and the fixed bolts 12 move towards the inner wall of the pressing wire end head body 7 through the threaded connection with the first sliding block 11. The movement of the fixed bolts 12 brings the left and right two moving wire clamping frames 17 closer to each other. The mutual approach of the two moving wire clamping frames 17 brings the multiple moving wire clamping cones 18 closer to each other. It should be noted that the moving wire clamping cones 18 corresponding to the left moving wire clamping frame 17 and the moving wire clamping cones 18 corresponding to the right moving wire clamping frame 17 are staggered, as shown in Figure 6 When the moving wire clamping cones 18 on both sides approach each other, the copper wire in the pressing wire end head body 7 can be clamped, and as the clamping progresses, the copper wire is bent and squeezed into the gap between the upper and lower adjacent two moving wire clamping cones 18. In this way, the copper wire is pressed and fastened between the multiple moving wire clamping cones 18. The copper wire needs to overcome the horizontal and vertical friction between the multiple moving wire clamping cones 18 to be separated, so the copper wire will be difficult to fall off, greatly increasing the installation and fastening degree of the copper wire. The tip angle of the moving wire clamping cone 18 is set to forty-five degrees. A relatively gentle tip angle is not easy to cause the copper wire to fall off or pierce the copper coin.

[0042] After the above operation is completed, the outer wall of the main cable insulation sheath 1 and the branch cable insulation sheath 6 can be baked with a spray gun to make them tightly wrap around the outer wall of the cable body 3 after deformation.

[0043] The stress cone 9 embedded in the cable terminal 4 can prevent the cable terminal 4 from being burned through at the moment of power-on. The copper terminal 8 at the end of the pressing wire end head body 7 can be used to install the pressing wire bolt at the position where the cable needs to be installed.

[0044] When the two moving wire clamping frames 17 on both sides move towards each other, the moving wire clamping frame 17 will move synchronously with the corresponding second guide rod 25. When the second guide rod 25 moves, the third sliding block 28 moves. The third sliding block 28 slides along the sliding guide in the first track groove 29. When the third sliding block 28 gradually slides into the second track groove 30 along the first track groove 29, since the second track groove 30 is set as an upward inclined track, at this time the third sliding block 28 will be guided upward by the second track groove 30, so that the third sliding block 28 brings the second guide rod 25 and the moving wire clamping frame 17 to bear upward force as a whole, so that the moving wire clamping frame 17 brings the mounting seat 14, the first ball 13, the fixed bolt 12 and the first sliding block 11 to bear upward force and slide as a whole, which promotes the first sliding block 11 to slide upward along the outer wall of the first guide rod 15. During the sliding process, the first return spring 16 is compressed upward;

[0045] The two moving wire clamping frames 17 move synchronously with the corresponding second return springs 19 and first guide rods 20 during the process of moving closer to each other. The first guide rods 20 slide along the inner wall of the guide frame 23 with the second guide rods 20, and the first guide rods 20 slide along the second sliding groove 24 with the second sliding block 21. When the moving wire clamping frame 17 moves upward as a whole, the moving wire clamping frame 17 compresses the second return spring 19 tightly.

[0046] The upward movement of the moving wire clamping frame 17 causes the corresponding multiple moving wire clamping cones 18 to move upward with the deformed copper wire being clamped, so that the copper wire is continuously pulled from the end of the cable body 3, and the copper wire that has been clamped and bent by the moving wire clamping cone 18 is further tightened in a bent state on the outer wall of the multiple moving wire clamping cones 18, further reducing the probability of copper wire falling off and increasing the installation and fastening degree of the copper wire.

[0047] Embodiment two: This embodiment is to solve the problem that when the copper wire is arranged in an inner and outer surrounding arrangement in a cable with a large number of copper wires, the copper wire arranged near the inner surrounding part cannot be pressed tightly, and the copper terminal has a risk of falling off after installation. This embodiment is an improvement based on embodiment one. For details, please refer to Figure 1 - Figure 11 The outer wall of the second guide rod 25 is fixedly connected with the abutting plate 26, and the third return spring 27 is sleeved on the second guide rod 25. One end of the third return spring 27 is fixedly connected with the outer wall of the abutting plate 26, and the other end of the third return spring 27 is fixedly connected with the outer wall of the third sliding block 28.

[0048] The inner wall of the wire pressing end body 7 is fixedly connected with the first abutting rod 31 and the second abutting rod 32, and the first abutting rod 31 and the second abutting rod 32 are both cylindrical.

[0049] In this embodiment, during the process of moving closer to each other of the two moving wire clamping frames 17, when the third sliding block 28 slides upward along the second track groove 30, the third sliding block 28 moves synchronously with the second guide rod 25, and the second guide rod 25 moves synchronously with the abutting plate 26 on the outer wall. The movement track of the left abutting plate 26 will press the outer wall of the second abutting rod 32, and the movement track of the right abutting plate 26 will press the outer wall of the first abutting rod 31, so that the abutting plates 26 on both sides are deflected in the clockwise direction at the same time after being pressed, and the abutting plates 26 are deflected with the second guide rod 25, the mounting seat 14 and the moving wire clamping frame 17 at the same time, which promotes the clockwise deflection of the moving wire clamping frames 17 on both sides by a certain angle, so that the copper wire clamped in the moving wire clamping frame 17 is bent by a certain angle from the clamping end of the moving wire clamping frame 17 along the end of the cable body 3, which can increase the friction between the outer wall of the wire pressing end body 7 and the end of the copper wire, and further improve the anti-falling measure of the copper wire.
