Description

Technical Field

[0001] The present invention relates to the technical field of cable joints, and specifically to a quick-connect combined cable joint. Background Art

[0002] A combined cable joint, also known as a modular cable joint, is a cable connection device mainly used for connecting two or more cables to achieve power transmission. It is mainly used in power systems, communication systems, and various automation devices. The design of the combined cable joint includes multiple electrical and mechanical connection components, which can connect the conductors and insulation layers of the cables simultaneously to ensure the safety and reliability of electrical connections.

[0003] Currently, when connecting two wires with a combined cable joint, in order to achieve good electrical conductivity between the two wires, it is necessary to remove the insulation layer outside the wires to expose the metal parts of the wires. Furthermore, during the wire connection process, it is necessary to strip the connection parts of the two wires. And due to the relatively many layers of the wires, the reliability of the connection needs to be ensured at each step, which leads to the overall cable installation process not being fast enough, thereby reducing the working efficiency of the combined cable joint.

[0004] Therefore, we propose a quick-connect combined cable joint to solve the problems raised above. Summary of the Invention

A connecting conductor for ensuring electrical connection between cables is provided inside the cable joint body. Cutting components are provided at both ends of the cable joint body. Both of the two cutting components include a positioning screw ring and a limiting ring for positioning the connecting joint part of the cable joint. Threaded tubes are threadedly connected to the outer surfaces of both of the two positioning screw rings. Two hand rings are fixedly installed on the outer surface of one side of both of the two threaded tubes by screws.

Circular tubes are fixedly installed on the outer surfaces of both of the two connecting tubes by screws. A plurality of strip-shaped slots are provided on the outer surfaces of both of the two circular tubes. A plurality of positioning slots for limiting the connecting parts in the cable joint are provided on the outer surfaces of both of the two circular tubes. The plurality of cutter blades are divided into two groups. An extension ring is fixedly installed between the outer surfaces of each group of cutter blades by bolts.

When it is necessary to connect two cables, first insert one end of one cable into the inside of one of the connecting tubes, so that a plurality of cutter blades move along the vertical direction of the cable, thereby cutting through the part outside the metal layer of the cable. Then rotate the cutter blade along the circumference of the cable to achieve all-round cutting of the part of the cable that needs to be skinned, and the skin of the part of the cable that needs to be cut can be separated from the other part of the cable. At this time, the cable can be pulled out of the inside of the connecting tube, and the staff can manually peel off the skin of the cut part of the cable, so that the metal part in the cable is completely exposed, which is convenient and fast, and solves the problem that the combined cable joints in the prior art generally do not have the function of peeling the cable, thus reducing the working efficiency of connecting combined cables.

[0008] Preferably, the inner walls of the two limiting rings are fixedly connected to the outer surfaces of the two connecting tubes respectively. Limiting slots are provided on the opposite outer surfaces of the cable joint body. The outer surfaces of the two positioning screw rings slide in the inner parts of the two limiting slots respectively.

The outer surfaces of the plurality of cutter blades slide in the inner parts of the plurality of strip-shaped slots respectively. The plurality of elastic balls are divided into two groups. The outer surfaces of each group of elastic balls are in contact with the outer surfaces of the two circular tubes respectively.

[0010] Preferably, both of the two rotating components include a rotating ring. Annular grooves are formed in the inner walls of the two rotating rings. The outer surfaces of the two extending rings are respectively rotatably connected to the inner parts of the two annular grooves. Mounting frames are fixed to the outer surfaces of the two rotating rings by bolts. Slide plates are fixedly installed on the inner walls of the two mounting frames. Both of the two slide plates are in a T shape.

[0012] Preferably, rubber gears are arranged on the outer surfaces of the two mounting columns. The two rubber gears and the two mounting columns are respectively arranged inside the two mounting frames. Rotating rods are movably embedded near one sides between the opposite inner walls of the two mounting frames; after the metal layer parts of the two cables are both peeled, the metal layer parts of the two cables are respectively inserted into the positions of the corresponding connecting conductors. During the movement of the two cables, the plurality of inclined clamping blocks are respectively pressed and move towards the inner wall direction of the communicating pipe, so that the plurality of springs are compressed and shortened. When one ends of the two cables are completely in contact with the outer surfaces of the connecting conductors, the connection of the two cables is completed. Through the action of the plurality of clamping blocks, the function of quickly connecting the two cables by the combined cable joint is realized, and the connection efficiency of the cables is further improved.

Clamping blocks are fixed between one ends of each group of springs. The plurality of springs are divided into two groups. One ends of each group of springs are respectively fixedly connected to the inner walls of the two communicating pipes; in order to prevent the driving gear from rotating during the process when rotation is not required, when the driving gear rotates, the rubber gear is pressed, so that the contact surface part of the rubber gear and the convex part of the driving gear deforms towards the center of the mounting column, realizing the limit of the driving gear and preventing it from rotating randomly. The rubber ring plays a role in limiting the rotating ring and preventing it from rotating randomly along the extending ring.

When one end of the two cables is completely in contact with the outer surface of the connecting conductor, the connection of the two cables is completed. Through the action of multiple clamping blocks, the function of quickly connecting two cables by the combined cable joint is realized, and the connection efficiency of the cable is further improved.

[0019] 3. In the present invention, in order to prevent the driving gear from rotating during the process when it does not need to rotate, when the driving gear rotates, the rubber gear is squeezed, so that the contact surface part of the rubber gear and the convex part of the driving gear deforms towards the center of the mounting column, realizing the limit of the driving gear and preventing it from rotating randomly. The rubber ring plays a role in limiting the rotating ring and preventing it from rotating randomly along the extension ring. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1-7, the present invention provides a technical solution: a quick-connect combined cable joint, including a cable joint body 1 and two rotating components 5. Inside the cable joint body 1, there is a connecting conductor 2 for ensuring electrical connection between cables. At both ends of the cable joint body 1, there are cutting components 4. Each of the two cutting components 4 includes a positioning screw ring 402 and a limiting ring 401 for positioning the connecting joint part of the cable joint. On the outer surface of each of the two positioning screw rings 402, there is a threaded tube 403 threadedly connected. On one side outer surface of each of the two threaded tubes 403, there are two hand rings 404 fixedly installed by screws. On the other side outer surface of each of the two threaded tubes 403, there are a plurality of cutting knives 405 for cutting the cable skin fixedly installed. At both ends of the cable joint body 1, there are communicating tubes 406 fixedly installed for protecting the cable surface. On the outer surface of each of the two communicating tubes 406, there are a plurality of card slots 407 for the movement of the plurality of cutting knives 405. On the outer surface of each of the two communicating tubes 406, there are circular tubes 408 fixedly installed by screws. On the outer surface of each of the two circular tubes 408, there are a plurality of strip-shaped slots 409. On the outer surface of each of the two circular tubes 408, there are a plurality of positioning slots 410 for limiting the connecting parts in the cable joint. The plurality of cutting knives 405 are divided into two groups. Between the outer surfaces of each group of cutting knives 405, there is an extension ring 411 fixedly installed by bolts. The inner walls of the two extension rings 411 slide on the outer surfaces of the two communicating tubes 406 respectively. On the outer surfaces of the two extension rings 411, there are rubber rings 412 for increasing friction. On the inner walls of the two extension rings 411, there are a plurality of elastic balls 413 for limiting. The inner walls of the two limiting rings 401 are fixedly connected to the outer surfaces of the two communicating tubes 406 respectively. On the opposite outer surfaces of the cable joint body 1, there are limiting slots 3. The inner parts of the two limiting slots 3 slide on the outer surfaces of the two positioning screw rings 402 respectively. The inner walls of the two threaded tubes 403 slide on the outer surfaces of the two communicating tubes 406 respectively. The outer surfaces of the plurality of cutting knives 405 slide inside the plurality of card slots 407 respectively. The inner parts of the plurality of strip-shaped slots 409 slide on the outer surfaces of the plurality of cutting knives 405 respectively. The plurality of elastic balls 413 are divided into two groups. The outer surfaces of each group of elastic balls 413 contact the outer surfaces of the two circular tubes 408 respectively.

[0033] In this embodiment, when it is necessary to connect two cables, first insert one end of one cable into the inside of one of the communicating tubes 406. Among them, as Figure 2As shown, the internal cross-section of the connecting pipe 406 is L-shaped. When one end of the cable is inserted into a position in contact with the outer wall of the smaller inner diameter part of the connecting pipe 406, the cable cannot move forward any further. Among them, the inner diameter of the smaller inner diameter part of the connecting pipe 406 matches the outer diameter of the metal layer in the cable, and the inner diameter of the larger inner diameter part of the connecting pipe 406 matches the outer diameter of the entire cable. At this time, the positioning screw ring 402 can be rotated to drive one end of the positioning screw ring 402 to move into the inside of the limiting groove 3, so that it separates from the threaded pipe 403. Among them, as Figure 5 shown, the internal cross-section of the limiting groove 3 matches the external cross-section of the positioning screw ring 402, both of which are L-shaped, and the limiting groove 3 is relatively deep. The purpose is to limit the positioning screw ring 402 while facilitating its rotation. After the positioning screw ring 402 separates from the threaded pipe 403, the staff can manually push the two hand rings 404 in the direction of the matching circular pipe 408, thereby driving the multiple cutting knives 405 to move along the directions of the multiple card slots 407 respectively. Among them, the outer surfaces of the multiple cutting knives 405 are all inserted into the inside of the smaller inner diameter part of the connecting pipe 406 and are on the same plane as the inner wall of the smaller part. When the multiple cutting knives 405 move to the position of the larger inner diameter part of the connecting pipe 406, the outer shell outside the cable metal layer can be cut, realizing the cutting of the cable skin, and the cutting process is relatively safe. It does not require the staff to manually use an exposed tool for cutting, further improving the safety of the staff when using the combined cable joint to connect the cable.

[0034] As Figures 1-9As shown in the figure, a quick-connect combined cable joint includes a cable joint body 1 and two rotating components 5. Inside the cable joint body 1, there is a connecting conductor 2 for ensuring electrical connection between cables. Cutting components 4 are provided at both ends of the cable joint body 1. Each of the two cutting components 4 includes a positioning screw ring 402 and a limiting ring 401 for positioning the connecting joint part of the cable joint. Threaded tubes 403 are threadedly connected to the outer surfaces of the two positioning screw rings 402. Two hand rings 404 are fixedly installed on the outer surface of one side of each of the two threaded tubes 403 by screws. A plurality of cutter blades 405 for cutting the cable skin are fixedly installed on the outer surface of the other side of each of the two threaded tubes 403. Connecting tubes 406 for protecting the cable surface are fixedly installed at both ends of the cable joint body 1. A plurality of slots 407 for the movement of the plurality of cutter blades 405 are provided on the outer surfaces of the two connecting tubes 406. Circular tubes 408 are fixedly installed on the outer surfaces of the two connecting tubes 406 by screws. A plurality of strip-shaped grooves 409 are provided on the outer surfaces of the two circular tubes 408. A plurality of positioning grooves 410 for limiting the connecting parts in the cable joint are provided on the outer surfaces of the two circular tubes 408. The plurality of cutter blades 405 are divided into two groups. An extension ring 411 is fixedly installed between the outer surfaces of each group of cutter blades 405 by bolts. The inner walls of the two extension rings 411 are slidably connected to the outer surfaces of the two connecting tubes 406 respectively. Rubber rings 412 for increasing friction are provided on the outer surfaces of the two extension rings 411. A plurality of elastic balls 413 for limiting are provided on the inner walls of the two extension rings 411. The inner walls of the two limiting rings 401 are fixedly connected to the outer surfaces of the two connecting tubes 406 respectively. Limiting grooves 3 are provided on the opposite outer surfaces of the cable joint body 1. The inner parts of the two limiting grooves 3 are slidably connected to the outer surfaces of the two positioning screw rings 402 respectively. The inner walls of the two threaded tubes 403 are slidably connected to the outer surfaces of the two connecting tubes 406 respectively. The outer surfaces of the plurality of cutter blades 405 are slidably connected to the inside of the plurality of slots 407 respectively. The inner parts of the plurality of strip-shaped grooves 409 are slidably connected to the outer surfaces of the plurality of cutter blades 405 respectively. The plurality of elastic balls 413 are divided into two groups. The outer surfaces of each group of elastic balls 413 are in contact with the outer surfaces of the two circular tubes 408 respectively. Each of the two rotating components 5 includes a rotating ring 501. Annular grooves 502 are provided on the inner walls of the two rotating rings 501. The inner parts of the two annular grooves 502 are rotatably connected to the outer surfaces of the two extension rings 411 respectively. Mounting brackets 503 are fixedly installed on the outer surfaces of the two rotating rings 501 by bolts. Slide plates 504 are fixedly installed on the inner walls of the two mounting brackets 503. The two slide plates 504 are both in a T shape. Tooth rows 505 are slidably connected to the outer surfaces of the two slide plates 504. A cutting knife 506 for annularly cutting the cable is fixed at one end of each of the two tooth rows 505. A rotating shaft 507 is movably embedded near the center between the opposite inner walls of the two mounting brackets 503. Mounting columns 508 are fixedly sleeved near the center on the outer surfaces of the two rotating shafts 507. Rubber gears 511 are provided on the outer surfaces of the two mounting columns 508.Two rubber gears 511 and two mounting posts 508 are respectively arranged inside two mounting brackets 503. Rotating rods 512 are movably embedded near one side between the opposite inner walls of the two mounting brackets 503. Drive gears 509 are fixedly sleeved near the centers on the outer surfaces of the two rotating rods 512. The outer surfaces of the two drive gears 509 are respectively meshed with the outer surfaces of two tooth rows 505. The outer surfaces of the two drive gears 509 are respectively meshed with the outer surfaces of the two rubber gears 511. The two drive gears 509 are respectively arranged inside the two mounting brackets 503. One ends of the two rotating rods 512 are fixedly installed with torsion blocks 510. The two torsion blocks 510 are respectively arranged outside the two mounting brackets 503.,

[0035] In this embodiment, while the cable skin is being cut as the multiple cutting blades 405 move, the extension ring 411 is also driven to move forward, thereby driving the multiple elastic balls 413 arranged inside the extension ring 411 to move along the surface of the communication pipe 406. The communication pipe 406 exerts a squeezing effect on the elastic balls 413. When the multiple elastic balls 413 respectively move into the corresponding positioning grooves 410, the multiple elastic balls 413 expand under the action of their own elastic forces and are respectively embedded into the multiple positioning grooves 410, that is, the positioning of the extension ring 411 is realized. At this time, the extension ring 411 just drives the cutting blade 506 to move to the outside of the communication pipe 406. Among them, the outer surface of the cutting blade 506 is in contact with one end of the multiple cutting blades 405. The purpose is to realize all-round cutting of the part of the cable that needs to be skinned. Then, the staff can rotate the torsion block 510 to drive the rotating rod 512 to rotate, and then drive the drive gear 509 to rotate. The drive gear 509 drives the tooth row 505 to move along the slide plate 504 towards the outer surface of the cable. Among them, as Figures 8-9As shown, the cross-section of the skateboard 504 is in the shape of a "work" character and matches the cross-section of the other side of the tooth row 505. The purpose is to limit the tooth row 505 while facilitating its movement along the skateboard 504. When one end of the cutting knife 506 moves to the outer surface of the metal part in the cable, the tooth row 505 just moves to the position where the end face contacts the driving gear 509. At this time, the staff can rotate the mounting bracket 503 along the outer surface of the rotating ring 501. Among them, in order to prevent the driving gear 509 from rotating during the process when it does not need to rotate, when the driving gear 509 rotates, the rubber gear 511 is squeezed, so that the contact surface part of the rubber gear 511 and the protrusion of the driving gear 509 deforms towards the center of the mounting post 508. When the protrusion part of the driving gear 509 no longer squeezes the protrusion part of the rubber gear 511, the protrusion part of the rubber gear 511 will reset under the action of its own elastic force, realizing the limit of the driving gear 509 and preventing it from rotating randomly. The rubber ring 412 plays a role in limiting the rotating ring 501 to prevent it from rotating randomly along the extension ring 411. The rotation of the mounting bracket 503 drives the cutting knife 506 to rotate along the skin of the cable. When the cutting knife 506 rotates one week along the rotating ring 501, the cable is rotated and cut one week. Since the outer surface of the cutting knife 506 contacts the outer surfaces of multiple cutting knives 405, after the cutting knife 506 rotates one week along the skin of the cable, the skin of the part of the cable that needs to be cut can be separated from the other parts of the cable. At this time, the cable can be pulled out of the inside of the communication pipe 406, and the staff can manually peel off the skin of the cut part of the cable, making the metal part in the cable completely exposed, which is convenient, fast, does not hurt the hand, improves the working efficiency of connecting the cable by the combined cable joint, and solves the problem in the prior art that most of the combined cable joints do not have the function of peeling the cable, thus reducing the working efficiency of connecting the combined cable.

[0036] As Figures 1-2 and Figure 5 shown, a plurality of springs 6 are provided on the inner walls of the two communication pipes 406. Every three adjacent springs 6 form a group, and a clamping block 7 is fixed between the ends of each group of springs 6. The plurality of springs 6 are divided into two groups, and the ends of each group of springs 6 are respectively fixedly connected to the inner walls of the two communication pipes 406.

[0037] In this embodiment, after the skin of one of the cables is peeled off, one end of the other cable is inserted into the interior of the other connecting pipe 406 in the same way, and the interior of the second embodiment part can be repeated. After the skins of both cables are peeled off, the metal layer parts of the two cables are respectively inserted into the positions of the corresponding connecting conductors 2. Among them, the connecting conductor 2 is made of metal copper, and its function is to ensure the electrical connection between the cables, transmit current and maintain the functionality of the cable system. During the movement of the two cables, the plurality of inclined clamping blocks 7 are respectively squeezed and move towards the inner wall direction of the connecting pipe 406, so that the plurality of springs 6 are squeezed and shortened. Among them, as Figure 2 shown, the contact surfaces of the plurality of clamping blocks 7 and the cables are all arc-shaped surfaces, and the purpose is to further strengthen the extrusion of the cables and realize the clamping and fixing of the cables. When one end of the two cables is completely in contact with the outer surface of the connecting conductor 2, the connection of the two cables is completed. Through the action of the plurality of clamping blocks 7, the effect of quickly connecting the two cables by the combined cable joint is realized, and the connection efficiency of the cables is further improved.

[0038] Usage method and working principle of this device: When it is necessary to connect two cables, first insert one end of one cable into the inside of one of the connecting tubes 406. When one end of the cable is inserted to a position where it contacts the outer wall of the smaller inner diameter part in the connecting tube 406, the cable can no longer move forward. Among them, the inner diameter of the smaller inner diameter part in the connecting tube 406 matches the outer diameter of the metal layer in the cable, and the inner diameter of the larger inner diameter part in the connecting tube 406 matches the outer diameter of the entire cable. At this time, the positioning screw ring 402 can be rotated to drive one end of the positioning screw ring 402 to move into the inside of the limiting groove 3, so that it separates from the threaded tube 403. After the positioning screw ring 402 separates from the threaded tube 403, the staff can manually push the two bracelets 404 in the direction of the corresponding round tube 408, thereby driving the multiple cutting knives 405 to move along the directions of the multiple card slots 407 respectively. Among them, the outer surfaces of the multiple cutting knives 405 are all inserted into the inside of the smaller inner diameter part in the connecting tube 406 and are on the same plane as the inner wall of the smaller part. When the multiple cutting knives 405 move to the position of the larger inner diameter part of the connecting tube 406, the outer casing outside the cable metal layer can be cut, realizing the cutting of the cable epidermis, and the cutting process is relatively safe, without the need for the staff to manually use an exposed knife for cutting. While the multiple cutting knives 405 move to cut the cable epidermis, they also drive the extension ring 411 to move forward, thereby driving the multiple elastic balls 413 arranged in the extension ring 411 to move along the surface of the connecting tube 406, and the connecting tube 406 plays a role in squeezing the elastic balls 413. When the multiple elastic balls 413 respectively move into the inside of their corresponding positioning grooves 410, the multiple elastic balls 413 expand respectively under the action of their own elasticity and are respectively embedded into the inside of the multiple positioning grooves 410, that is, the positioning of the extension ring 411 is realized. At this time, the extension ring 411 just drives the cutting knife 506 to move to the outside of the connecting tube 406. Among them, the outer surface of the cutting knife 506 is in contact with one end of the multiple cutting knives 405. Then the staff can rotate the torsion block 510 to drive the rotating rod 512 to rotate, and further drive the driving gear 509 to rotate. The driving gear 509 drives the tooth row 505 to move along the slide plate 504 to the outer surface of the cable. When one end of the cutting knife 506 moves to the outer surface of the metal part in the cable, the tooth row 505 just moves to the position where the end face contacts the driving gear 509. At this time, the staff can rotate the mounting bracket 503 along the outer surface of the rotating ring 501. The rotation of the mounting bracket 503 drives the cutting knife 506 to rotate along the epidermis of the cable. When the cutting knife 506 rotates one week along the rotating ring 501, the cable is rotated and cut one week. Since the outer surface of the cutting knife 506 is in contact with the outer surfaces of the multiple cutting knives 405, after the cutting knife 506 rotates one week along the epidermis of the cable, the epidermis of the part of the cable that needs to be cut can be separated from the other parts of the cable. At this time, the cable can be pulled out of the inside of the connecting tube 406.The staff can manually strip the skin of the cut part of the cable, making the metal part in the cable completely exposed, which is convenient, fast, and does not hurt the hands, improving the working efficiency of connecting the cable with the combined cable joint. Among them, in order to prevent the driving gear 509 from rotating during the process when rotation is not required, when the driving gear 509 rotates, the rubber gear 511 is squeezed, causing the contact surface part of the rubber gear 511 and the protrusion of the driving gear 509 to deform towards the center of the mounting post 508. When the protrusion part of the driving gear 509 no longer squeezes the protrusion part of the rubber gear 511, the protrusion part of the rubber gear 511 will reset under the action of its own elastic force, realizing the limit of the driving gear 509. After the skin of one cable is peeled off, insert one end of the other cable into the other communicating pipe 406 in the same way, and repeat the steps in the second embodiment part. After the skins of both cables are peeled off, insert the metal layer parts of the two cables into the corresponding positions of the connecting conductor 2 respectively. Among them, the connecting conductor 2 is made of metal copper, and its function is to ensure the electrical connection between the cables, transmit current and maintain the functionality of the cable system. During the movement of the two cables, the plurality of inclined clamping blocks 7 are respectively squeezed and move towards the inner wall of the communicating pipe 406, and then the plurality of springs 6 are squeezed and shortened. For example, Figure 2 As shown, the contact surfaces of the plurality of clamping blocks 7 and the cable are all arc-shaped, and the purpose is to further strengthen the extrusion of the cable and realize the clamping and fixing of the cable. When one end of the two cables is completely in contact with the outer surface of the connecting conductor 2, the connection of the two cables is completed.

[0039] The wiring diagram of the cable joint body 1 and the connecting conductor 2 in the present invention belongs to the common knowledge in the art, and its working principle is already known technology. The model is selected according to the actual use, so the control method and wiring layout of the cable joint body 1 and the connecting conductor 2 will not be explained in detail.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
