Description

Technical Field

[0001] The present invention relates to the technical field of cable connection, in particular to an engineering cable adapter for electromechanical installation. Background Art

[0002] Cable adapters, core components for connecting cables and enabling current transmission and signal control, are widely used in power systems, communication base stations, industrial automation equipment, and other applications. Especially in applications with compact space and complex wiring, curved cable adapters, with their flexible layout and adaptability, have become a key component for efficiently connecting power interfaces and cables.

[0003] However, the current structure of the curved adapters in the industry is simple. When connecting cables, the angle of the adapter is generally fixed, which makes it difficult to adapt to special spaces or special wiring requirements. When there are irregular corners in the installation space, the fixed-angle adapter may make cable installation difficult or even impossible.

[0004] Chinese patent CN222320599U discloses a curved through-hole connector. By providing a bendable tube that can be bent to the desired angle for installation, it can accommodate various bending angle requirements for wire output. However, in this solution, after the cable is stripped and the conductors are passed through the bend tube, the bending of the tube causes uneven stress on the conductors. Specifically, the conductors on one side experience less stress, while those on the other side experience greater stress. This can easily damage the insulation layer and even lead to conductor breakage, potentially causing poor contact, signal attenuation, or short circuits. Summary of the Invention

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only 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 making creative efforts are within the scope of protection of the present invention.

[0030] An embodiment of an engineering cable adapter for electromechanical installation of the present invention is as follows Figures 1 to 10 shown.

[0031] A cable adapter for electromechanical installation, used to connect two cables 100, includes a plug-in end 200 and a fixed end 300. The two cables 100 are connected to the plug-in end 200 and the fixed end 300, respectively. The plug-in end 200 can move toward the fixed end 300 and plug into the fixed end 300, thereby achieving electrical connection between the two cables 100. The direction in which the plug-in end 200 and the fixed end 300 are plugged together is referred to as a first direction.

[0032] The plug end 200 and the fixed end 300 are rotatably connected. A portion of the cable 100 within the plug end 200 corresponds to the pivotal connection between the plug end 200 and the fixed end 300. This allows the portion of the cable 100 within the plug end 200 to rotate in a second direction perpendicular to the first direction. Furthermore, the conductors 102 of the portion of the cable 100 corresponding to the pivotal connection between the plug end 200 and the fixed end 300 are exposed.

[0033] The two ends of the portion of the cable 100 corresponding to the rotational connection between the plug-in end 200 and the fixed end 300 in the first direction are respectively referred to as the first end and the second end. The first end is located on the side of the second end close to the fixed end 300 in the first direction. The first end is used to be plugged into the fixed end 300, and the second end can rotate around the first direction relative to the first end.

[0034] Furthermore, the second end can rotate one circle around the first direction relative to the first end.

[0035] Specifically, the cable 100 includes a plurality of conductors 102 and an insulating sheath 101 covering the plurality of conductors 102 . The plurality of conductors 102 are evenly distributed in a first direction within the insulating sheath 101 , wherein three conductors 102 are provided.

[0036] This embodiment utilizes a mating end 200 and a fixed end 300 for mating. During use, the user first holds the mating end 200 close to the fixed end 300 to connect the mating end 200 and the fixed end 300. The second end of the cable 100, located within the mating end 200, is then rotated relative to the first end in a first direction. This rotation of the cable 100 causes the multiple conductors 102 within the cable 100 to twist in an orbital manner. The mating end 200 and the fixed end 300 are then rotated to the desired angle to adjust the bending angle of the adapter.

[0037] For the sake of convenience, the portion of the cable 100 corresponding to the rotational connection between the plug end 200 and the fixed end 300 is referred to as a curved cable segment, that is, when bending, the two ends of the curved cable segment approach each other, and thereby the two ends of the multiple conductors 102 in the curved cable segment will also approach each other, with the axis at the rotation point as the boundary. Since the multiple conductors 102 are misaligned with each other after twisting, each conductor 102 has a portion with a smaller degree of pressure and a portion with a larger degree of pressure, thereby making the bending degree of each conductor 102 as consistent as possible, thereby improving the force uniformity of the conductors 102 inside the cable 100 and weakening the adverse effects of the adapter on the conductors 102 inside the cable 100 when bending.

[0038] That is, compared to simply bending multiple conductors 102, conductors 102 near the rotation point are subjected to greater pressure, while conductors 102 farther from the rotation point are subjected to less pressure. By rotating the second end of the curved cable segment relative to the first end about a first direction, this embodiment eliminates the need for a single conductor 102 to bear excessive pressure, resulting in more even stress on the conductors 102.

[0039] In a further embodiment, the plug end 200 includes a connection portion, which includes a connector 210, a connecting tube 220, and a socket 230. The connector 210, the connecting tube 220, and the socket 230 are arranged sequentially in a first direction, with the connector 210 located on a side of the socket 230 that is farther from the fixed end 300 in the first direction. The connecting tube 220 is bendable. Specifically, the connecting tube 220 is a flexible metal tube.

[0040] The cable 100 passes through the connector 210 and the connecting tube 220 in sequence along the first direction and is connected to the socket 230. The socket 230 is used to be plugged into the fixed end 300. The connecting tube 220 is arranged along the first direction. One end of the connecting tube 220 is fixedly connected to the socket 230, and the other end is connected to the connector 210. The connecting tube 220 and the connector 210 can move synchronously and rotate relative to each other.

[0041] In a further embodiment, the connector 210 includes a connecting tube 211 and a first locking portion. The multiple wires 102 inside the cable 100 can all pass through the connecting tube 211 along the first direction. The first locking portion can lock the cable 100 and the connecting tube 211, so that the cable 100 can move synchronously with the connecting tube 211.

[0042] The connecting tube 211 is provided with a plurality of through slots which penetrate in the first direction. The through slots are arranged in one-to-one correspondence with the wires 102 , and each wire 102 can pass through the corresponding through slot along the first direction.

[0043] Specifically, an annular groove is provided at one end of the connecting tube 220 close to the connecting tube 211 in the first direction. The annular groove is coaxially arranged with the connecting tube 220, and a protrusion for rotating with the annular groove is coaxially arranged on the connecting tube 211, so that the connecting tube 220 and the connecting tube 211 can move synchronously and rotate relative to each other.

[0044] Among them, the first locking part includes a crimping tube 212 and a crimping ring 213. The crimping tube 212 is sleeved on the insulation skin 101 of the cable 100 and is located on the side of the connecting tube 211 away from the connecting tube 220 in the first direction. One end of the crimping tube 212 in the first direction is screwed to the connecting tube 211, and the other end of the crimping tube 212 in the first direction is fixed with a plurality of pressing pieces 214, and the pressing pieces 214 are elastic. The plurality of pressing pieces 214 are evenly distributed in the circumferential direction of the crimping tube 212, and the plurality of pressing pieces 214 are integrally formed with the crimping tube 212. The crimping ring 213 is sleeved on the crimping tube 212 and is threadedly matched with the crimping tube 212. When the crimping ring 213 is installed on the crimping tube 212, the plurality of pressing pieces 214 can clamp the cable 100 and enable the cable 100 to move with the crimping tube 212.

[0045] The crimping ring 213 includes a threaded section and a clamping section, which are arranged in sequence in the first direction and fixedly connected. The threaded section is threadedly matched with the crimping tube 212, and the clamping section can be crimped with the pressing piece 214. The inner diameter of the clamping section is smaller than the outer diameter of the ring formed after the multiple pressing pieces 214 are sleeved on the cable 100. Therefore, when the crimping ring 213 is installed with the crimping tube 212, the clamping section will tighten the multiple pressing pieces 214, clamp the cable 100, and enable the cable 100 to move with the crimping tube 212.

[0046] By providing the first locking portion, during installation, the connecting cylinder 211 and the crimping cylinder 212 are first screwed together, and then the clamping ring and the crimping cylinder 212 are screwed together. At this time, the connecting cylinder 211, the crimping cylinder 212, the crimping ring 213 and the cable 100 form an integrated structure.

[0047] In a further embodiment, the plug end 200 further includes a rotating cylinder 240, and the fixed end 300 includes a fixed cylinder 310. Both the rotating cylinder 240 and the fixed cylinder 310 are arranged along a first direction. The rotating cylinder 240 is sleeved on the connecting cylinder 211 of the connecting member 210. The rotating cylinder 240 and the fixed cylinder 310 are rotatably connected at one end thereof that is close to each other in the first direction via a rotating arm, and the rotating arm can only rotate in one direction. The socket 230 can be plugged into the fixed cylinder 310.

[0048] By rotatably connecting the rotating cylinder 240 and the fixed cylinder 310 via the rotating arm and making the rotating arm rotate in one direction, the rotating arm can be prevented from returning to its original position after being bent.

[0049] The rotating arm includes a first rotating arm 241 and a second rotating arm 311. Both the first rotating arm 241 and the second rotating arm 311 are arranged along a first direction. The first rotating arm 241 is connected to the rotating cylinder 240, and the second rotating arm 311 is connected to the fixed cylinder 310. They are an integrally formed structure. The first rotating arm 241 and the second rotating arm 311 are rotatably engaged via a one-way bearing, allowing the rotating arm to rotate only in one direction.

[0050] Furthermore, two first rotating arms 241 and two second rotating arms 311 are provided. The two first rotating arms 241 are evenly distributed along the circumference of the rotating cylinder 240 and arranged side by side in the second direction. The two second rotating arms 311 are evenly distributed along the circumference of the fixed cylinder 310 and arranged side by side in the second direction. The first rotating arms 241 and the second rotating arms 311 are provided in a one-to-one correspondence, and the first rotating arms 241 and the corresponding second rotating arms 311 are rotatably engaged via a one-way bearing.

[0051] Alternatively, the first rotating arm 241 and the second rotating arm 311 are rotationally matched via the one-way gear 242 , and the one-way gear 242 is mounted on the first rotating arm 241 or the second rotating arm 311 via the limiting plate 243 .

[0052] Specifically, a limiting groove for accommodating the limiting plate 243 is defined on the one-way gear 242 .

[0053] Specifically, a first rotating hole is formed on the first rotating arm 241, and a second rotating hole is formed on the second rotating arm 311. The second rotating hole is provided with a telescopic tooth for cooperating with the one-way gear 242. The one-way gear 242 can pass through the first rotating hole and the second rotating hole in sequence and cooperate with the telescopic tooth.

[0054] During use, the one-way gear 242 is sequentially passed through the first and second rotating holes and engaged with the telescopic teeth. The limiting plate 243 is then installed between the one-way gear 242 and the first rotating arm 241. The limiting plate 243 is locked to the first rotating arm 241 with a bolt to prevent the one-way gear 242 from axially moving. The second direction is the axial direction of the one-way gear 242.

[0055] Furthermore, the rotating arm can be extended and retracted in the first direction. Specifically, a waist-shaped sliding groove is provided on the first rotating arm 241, and the waist-shaped sliding groove is arranged along the first direction. The first rotating arm 241 is provided with a slider, which slides in cooperation with the waist-shaped sliding groove, so that the first rotating arm 241 and the second rotating arm 311 have a certain amount of movable margin when the first rotating arm 241 and the second rotating arm 311 rotate.

[0056] In a further embodiment, the rotating cylinder 240 is screwed together with the connecting cylinder 211, and a rotation stop is provided on the socket 230, which can limit the socket 230 from rotating in a first direction. That is, in the first direction, the socket 230 and the first end of the cable 100 are located on the same side, and the connecting cylinder 211 and the second end of the cable 100 are located on the same side.

[0057] Specifically, the socket 230 includes a plug block 231 and a plurality of plug terminals 232. The plug block 231 is arranged along a first direction and fixedly connected to the connecting tube 220. The plurality of plug terminals 232 are evenly distributed on the plug block 231 around the first direction. The plug terminals 232 are arranged in a one-to-one correspondence with the wires 102, and each wire 102 is plugged into its corresponding plug terminal 232. A plurality of fixed terminals 312 are arranged within the fixed cylinder 310. The plurality of fixed terminals 312 are evenly distributed around the first direction within the fixed cylinder 310. The wires 102, the fixed terminals 312, and the plug terminals 232 are arranged in a one-to-one correspondence. The two ends of the fixed terminals 312 along the first direction are respectively connected to the corresponding wires 102 and the corresponding plug terminals 232.

[0058] The anti-rotation part includes a plurality of latching rods 233, which are evenly distributed around the first direction on the plug-in block 231 of the socket 230. The latching rods 233 are arranged along the first direction. The end of the latching rod 233 away from the plug-in block 231 in the first direction can be latched with the fixed cylinder 310, and when the latching rod 233 is latched with the fixed cylinder 310, the spiral transmission between the rotating cylinder 240 and the connecting cylinder 211 takes effect.

[0059] A spiral groove 244 is provided on the inner wall of the rotating cylinder 240 , and a rotating block 215 for cooperating with the spiral groove 244 is provided on the connecting cylinder 211 . When the clamping rod 233 is engaged with the fixed cylinder 310 , the rotating block 215 slides and cooperates with the spiral groove 244 .

[0060] The fixing tube 310 is provided with a plurality of slots, which are arranged in a one-to-one correspondence with the locking rods 233 .

[0061] This embodiment, by providing a rotation stop, keeps the fixed end 300 stationary during use, and then connects the rotating cylinder 240 and the fixed cylinder 310 via a rotating arm. The entire connecting portion is then held and moved toward the fixed end 300. After the latching rod 233 engages the fixed cylinder 310, as the connecting portion continues to move, the spiral transmission between the rotating cylinder 240 and the connecting cylinder 211 takes effect. Since the fixed end 300 is stationary, the rotating cylinder 240, which is connected to the fixed cylinder 310 via the rotating arm, also does not move. The spiral transmission between the connecting cylinder 211 and the rotating cylinder 240 causes the rotating cylinder 240 to move in the first direction while rotating around the first direction, driving the entire connecting portion to rotate. Therefore, the second end of the cable 100 rotates around the first direction relative to the first end, driving the multiple conductors 102 inside it to twist in an orbital rotation.

[0062] Furthermore, the fixed end 300 also includes a second locking portion 320, which can lock the cable 100 and the fixing tube 310, allowing the cable 100 to move synchronously with the fixing tube 310. The first locking portion and the second locking portion 320 have the same structure, except that the crimping tube 212 of the first locking portion is threadedly connected to the connecting tube 211 and is located on the side of the connecting tube 211 away from the connecting tube 220 in the first direction, while the crimping tube 212 of the second locking portion 320 is threadedly connected to the fixing tube 310 and is located on the side of the fixing tube 310 away from the connecting tube 220 in the first direction.

[0063] In a further embodiment, a limiter is provided inside the connecting cylinder 211, which can move the plurality of conductors 102 on the cable 100 along the radial direction of the cable 100 toward a side away from the central axis of the cable 100. Furthermore, a limiter is also provided inside the fixing cylinder 310.

[0064] The limiting member is a limiting block 400, which is provided with a plurality of through holes, each corresponding to one of the wires 102. The through holes extend through the first direction. The two ends of the through holes in the first direction are referred to as the inlet end and the outlet end, respectively. The inlet end is located on the side of the outlet end connected thereto, closer to the central axis of the cable 100 in the radial direction of the cable 100. As a result, when the wires 102 enter the limiting block 400 from the inlet end side and extend from the outlet end side, each wire 102 will move along the radial direction of the cable 100 toward the side away from the central axis of the cable 100.

[0065] By setting the limit block 400, when in use, the wire 102 is passed through the through hole set corresponding to it, and the end of the insulation skin 101 of the cable 100 is abutted against the end face of the limit block 400, and the wires 102 passing through the through hole will further move away from each other along the radial direction of the cable 100, thereby increasing the spacing between the multiple wires 102 in the circumferential direction of the cable 100, and preventing the wires 102 from being squeezed close to each other during subsequent twisting and bending.

[0066] In combination with the above embodiment, the specific working process is as follows:

[0067] During installation, the fixing cylinder 310 and the corresponding cable 100 are first connected, and then the fixing cylinder 310 and the cable 100 are locked using the second locking portion 320 .

[0068] Keeping the fixed end 300 stationary, the rotating cylinder 240 and the fixed cylinder 310 are connected via a rotating arm. The entire connecting portion is then held and moved toward the fixed end 300. Once the latching rod 233 engages the fixed cylinder 310, the spiral transmission between the rotating cylinder 240 and the connecting cylinder 211 takes effect as the connecting portion continues to move. Since the fixed end 300 remains stationary, the rotating cylinder 240, connected to the fixed cylinder 310 via the rotating arm, also does not move. The spiral transmission between the connecting cylinder 211 and the rotating cylinder 240 causes the rotating cylinder 240 to move in the first direction while rotating about the first direction, driving the entire connecting portion to rotate. Consequently, the second end of the cable 100 rotates about the first direction relative to the first end, causing the multiple conductors 102 within it to twist in an orbital manner. The plug end 200 and the fixed end 300 are then rotated to the desired angle to adjust the bending angle of the adapter.

[0069] See also Figure 10 As shown, for the convenience of explanation, one of the wires 102 is taken as an example, and the wire 102 is named wire No. 103, and the rotation axis is used as the dividing point (the rotation axis is the axis of the one-way gear 242). When the curved cable segment is bent in the direction given by the arrow and its two ends are close to each other (after approaching, the two ends of the curved cable segment face the left side in the figure).

[0070] The portion of conductor 103 on the same side as the bent cable segment after bending is called first segment 104, and the remaining portion is called second segment 105. Therefore, after bending, first segment 104 moves more to the right and is subject to greater compression, while second segment 105 moves less to the right and is subject to less compression. At this point, conductor 103 has both sections subject to less compression and sections subject to greater compression. This releases and adjusts the deformation margin within conductor 103, improving the uniformity of force applied to conductor 103 and ensuring a consistent degree of bending across the entire conductor 103.

[0071] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
