Description

Technical Field

[0001] The present invention relates to the technical field of cables, in particular to a cable and a cable assembly. Background Art

[0002] Cable, as a key device for transmitting electric energy and signals, has a precise structure and is usually composed of multiple layers of components such as conductors, insulation layers, inner sheaths, armor and outer sheaths. As an indispensable medium for electric energy or signal transmission, cables have shown extensive application potential and broad development prospects in all walks of life.

[0003] For example, the patent with the authorization announcement number CN218351180U discloses a cable, including: a conductor; a conductor protection layer, which is coated on the conductor; wherein the conductor protection layer includes a metal component and an armor component, and the metal component and the armor component are mutually embedded. This cable solves the problem of low reliability and safety of cables in the prior art.

[0004] The above cables still have certain defects: Due to the physical property of the cable itself having a smooth surface, even if it is tightly bound by professional fixing tools such as clamps, it is still very easy to move when subjected to external forces, especially the continuous and non-negligible influence of gravity. During this displacement process, friction will inevitably occur between the cable and the fixing tool. Long-term friction will cause the outer sheath of the cable to gradually wear, and may expose the internal insulation layer or other key structures, which will not only seriously affect the transmission efficiency and service life of the cable, but may also cause serious problems such as short circuit and leakage. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a cable and a cable assembly, which prevents the cable body from being displaced after installation.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a cable, comprising a cable body, wherein the cable body comprises, from the inside to the outside, a conductor, an insulating inner sheath, an armor and an outer sheath, the outside of the conductor being fixedly connected with the insulating inner sheath, the outside of the insulating inner sheath being wound with armor, the outside of the armor being fixedly connected with the outer sheath, and the cross-section of the armor being an arc.

[0007] The present invention further provides a cable assembly, comprising a bridge frame for installing the above-mentioned cables, wherein a plurality of equidistantly distributed left clamps are fixedly connected to the interior of the bridge frame, the left clamps match the cable body, and a right clamp is provided on one side of each of the left clamps and is slidably connected to the bridge frame.

[0008] Furthermore, a fixing hole is opened at the lower end of the left clamp, a fixing bolt is slidably connected inside the fixing hole, and the lower end of the fixing bolt is threadedly connected to the bridge frame.

[0009] Furthermore, a positioning block is fixedly connected to one side of the upper end of the right clamp close to the left clamp, and slots are provided on the left clamp and the positioning block, an insert block is slidably connected inside the slot, one end of the insert block is fixedly connected to a connecting plate, one side of the connecting plate is fixedly connected to a gripping rod, an anti-drop block slidably connected to the gripping rod is fixedly connected to the outer wall of the left clamp, and an end plate is fixedly connected to the end of the gripping rod.

[0010] Furthermore, a slide groove is provided at the lower end of the inner side of the bridge frame, a slide plate is slidably connected inside the slide groove, a plurality of connecting blocks are fixedly connected to the top of the slide plate, and a connecting groove matching the connecting block is provided at the bottom of each right clamp.

[0011] Furthermore, one end of the slide plate is hinged with a hinge block, one end of the hinge block away from the slide plate is fixedly connected with a handle, and the outer wall of the bridge frame is fixedly connected with multiple groups of elastic blocks matching the hinge block.

[0012] Furthermore, a group of symmetrically arranged limit rods are fixedly connected to one side of the hinge block away from the bridge frame, and an extrusion block matching the elastic card block is slidably connected to the limit rod. The end of the limit rod away from one end of the hinge block is fixedly connected to a limit plate, and an elastic member is sleeved on the end of the limit rod away from the hinge block, one end of the elastic member is fixedly connected to the limit plate, and the other end of the elastic member is fixedly connected to the extrusion block.

[0013] Furthermore, a positioning plate is fixedly connected to the bottom of the slide plate near one end of the hinge block, and a positioning groove matching the positioning plate is formed at the end of the hinge block.

[0014] Compared with the prior art, the present invention has the following beneficial effects: For this type of cable, since the cross-section of the armor is arc-shaped, when the cable body is restrained by a fixing tool, the armor is squeezed and elastically deformed in the direction of the insulating inner sheath, so that the cable body forms a depression in the restrained area. In this way, after the fixing tool restrains the cable body, the cable body is not easily displaced, thereby avoiding damage to the outer sheath of the cable body due to friction. After the fixing tool is removed, the armor will return to its original state. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely 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 present invention, rather than all the embodiments.

[0018] See also Figure 1-6 A cable comprises a cable body 1, wherein the cable body 1 comprises a conductor 2, an insulating inner sheath 3, an armor 4 and an outer sheath 5 from the inside to the outside, the insulating inner sheath 3 is fixedly connected to the outside of the conductor 2, the armor 4 is wound around the outside of the insulating inner sheath 3, the outer sheath 5 is fixedly connected to the outside of the armor 4, and the cross-section of the armor 4 is an arc.

[0019] In the cable of the present invention, since the cross-section of the armor 4 is arc-shaped, when the cable body 1 is restrained by the fixing tool, the armor 4 is squeezed and elastically deformed in the direction of the insulating inner sheath 3 (the armor 4 will not be displaced after being deformed to a certain extent, so the armor 4 can protect the insulating inner sheath 3 and the conductor 2 inside the cable body 1), so that the cable body 1 forms a depression in the restrained area, so that after the fixing tool restrains the cable body 1, the cable body 1 is not easy to be displaced, and the outer sheath 5 of the cable body 1 is prevented from being damaged due to friction. After the fixing tool is removed, the armor 4 will return to its original state.

[0020] like Figure 1 , Figures 3 to 6 As shown, the present invention further provides a cable assembly, including a bridge 6 for installing the above-mentioned cable, wherein a plurality of equidistantly distributed left clamps 7 are fixedly connected to the interior of the bridge 6, the left clamps 7 are matched with the cable body 1, and a right clamp 13 slidably connected to the bridge 6 is provided on one side of each left clamp 7.

[0021] Specifically, when the cable body 1 needs to be installed and fixed, it is only necessary to place the cable body 1 between the left clamp 7 and the right clamp 13, and then fix the cable body 1 through the left clamp 7 and the right clamp 13. The fixing method is simple, convenient and easy to operate.

[0022] like Figure 3 and Figure 5 As shown, a fixing hole 8 is opened at the lower end of the left clamp 7, and a fixing bolt 9 is slidably connected inside the fixing hole 8, and the lower end of the fixing bolt 9 is threadedly connected to the bridge frame 6.

[0023] Specifically, the left clamp 7 is connected and fixed to the bridge frame 6 by means of the fixing bolts 9, so when the left clamp 7 needs to be replaced, it is relatively simple and convenient.

[0024] like Figure 3 , Figure 5 and Figure 6 As shown, a positioning block 15 is fixedly connected to one side of the upper end of the right clamp 13 close to the left clamp 7, a slot 16 is provided on the left clamp 7 and the positioning block 15, an insert block 17 is slidably connected inside the slot 16, a connecting plate 18 is fixedly connected to one end of the insert block 17, a gripping rod 19 is fixedly connected to one side of the connecting plate 18, an anti-slip block 21 slidably connected to the gripping rod 19 is fixedly connected to the outer wall of the left clamp 7, and an end plate 20 is fixedly connected to the end of the gripping rod 19.

[0025] Specifically, when connecting the left clamp 7 and the right clamp 13 together, it is only necessary to close the left clamp 7 and the right clamp 13 until the left clamp 7 and the slot 16 on the positioning block 15 are aligned, and then push the insert block 17 to make the insert block 17 fully inserted into the slot 16. The operation process is simple and convenient. At the same time, it is more convenient to move the insert block 17 through the grasping rod 19. In addition, an anti-slip block 21 and an end plate 20 are provided to limit the grasping rod 19 to avoid the loss of the insert block 17 and the grasping rod 19.

[0026] like Figure 3 , Figure 4 and Figure 5 As shown, a slide groove 10 is provided at the lower end of the inner side of the bridge frame 6, and a slide plate 11 is slidably connected inside the slide groove 10. A plurality of connecting blocks 12 are fixed to the top of the slide plate 11, and a connecting groove 14 matching the connecting block 12 is provided at the bottom of each right clamp 13.

[0027] Specifically, when the right clamp 13 needs to be moved, it is only necessary to push the slide plate 11 to drive a row of right clamps 13 to move together, making the movement of the right clamp 13 more convenient. In addition, since the right clamp 13 is connected and fixed to the slide plate 11 through the connecting block 12 and the connecting groove 14, the right clamp 13 is also relatively simple and convenient to replace.

[0028] like Figure 3 and Figure 4 As shown, a hinge block 22 is hinged at one end of the slide plate 11 , a handle 25 is fixedly connected to the end of the hinge block 22 away from the slide plate 11 , and a plurality of elastic blocks 26 matching the hinge block 22 are fixedly connected to the outer wall of the bridge frame 6 .

[0029] Specifically, after the right clamp 13 and the left clamp 7 are closed, the hinge block 22 will completely disengage from the slide slot 10. At this time, the hinge block 22 is rotated so that the hinge block 22 is stuck on the elastic block 26. In this way, the left clamp 7 and the right clamp 13 can be pre-fixed to facilitate the smooth insertion of the insert block 17 into the slot 16.

[0030] like Figure 3 and Figure 4 As shown, a group of symmetrically arranged limit rods 28 are fixedly connected to the side of the hinge block 22 away from the bridge frame 6, and an extrusion block 27 matching the elastic block 26 is slidably connected to the limit rod 28. The end of the limit rod 28 away from one end of the hinge block 22 is fixedly connected to a limit plate 29, and an elastic member 30 is sleeved on the end of the limit rod 28 away from the hinge block 22. One end of the elastic member 30 is fixedly connected to the limit plate 29, and the other end of the elastic member 30 is fixedly connected to the extrusion block 27.

[0031] Specifically, when the hinge block 22 needs to be removed from the elastic block 26, the extrusion block 27 can be pressed, and the extrusion block 27 will push the elastic block 26 to both sides so that the elastic block 26 no longer restricts the hinge block 22, making it easier to remove the hinge block 22 from the elastic block 26.

[0032] like Figure 3 and Figure 4 As shown, a positioning plate 23 is fixedly connected to the bottom of the slide plate 11 close to one end of the hinge block 22 , and a positioning groove 24 matching the positioning plate 23 is formed at the end of the hinge block 22 .

[0033] Specifically, the rotation angle of the hinge block 22 is limited by the positioning plate 23 , so that the hinge block 22 can rotate to a position aligned with the slide slot 10 , thereby facilitating the hinge block 22 to push the slide plate 11 to move.

[0034] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
