Description

Technical Field

[0001] The present invention relates to the technical field of electrical connection, and in particular to a connection device for cable connection. Background Art

[0002] In traditional cable connection technology, common connection devices (such as plugs, sockets, and terminal blocks) typically use mechanical contact or welding of metal conductors to achieve electrical conductivity. Early technologies suffered from unstable contact resistance, susceptibility to oxidation and corrosion, and loose connections caused by mechanical wear. In recent years, with the demand for high-frequency and high-speed transmission, connectors also need to consider characteristics such as impedance matching and interference shielding, and material processing is developing towards high density and modularization. The core of this background technology lies in balancing the three major factors of electrical performance, mechanical strength, and environmental adaptability. During the use of the connecting device for cable connection, the cable is first connected to the connecting port of the device, and then the connecting port of the device is connected to the main body of the device, and then the cable is driven to pass through the main body to the outside of the main body, so that the cable is connected to the device. Due to the process of connecting the device connecting port of the cable to the device, the device outlet is small, resulting in the cable bending inside the connecting device during connection, thereby affecting the connection quality of the cable during connection. Summary of the Invention

[0007] Furthermore, the pushing mechanism includes two springs 2 fixedly mounted on the inner wall of the fixed assembly, and the pushing mechanism includes: An extrusion assembly is mounted on the inner wall of the fixed assembly and is used to swing when the fixed assembly moves; The pushing component is installed inside the extrusion component and is used for moving inside the extrusion component.

[0008] Furthermore, the auxiliary component includes a plurality of extrusion plates 1 fixedly connected to the bottom of the conical plate, and the inner walls of the plurality of extrusion plates 1 are fixedly connected with auxiliary cylinders.

[0009] Furthermore, the contraction component includes an elastic cylinder fixedly connected to the top of the auxiliary cylinder, the top of the elastic cylinder is fixedly connected to a movable ring, the outer surface of the movable ring is provided with a plurality of rectangular grooves, and the interior of the rectangular groove is fixedly connected to a spring 1.

[0010] Furthermore, the sliding assembly includes a swing plate rotatably connected to the bottom of the lifting plate, and an end of the swing plate away from the lifting plate is rotatably connected to the push plate; The bottom of the lifting plate is fixedly connected to the top of the spring 1, and the pushing plate is slidably connected to the inside of the rectangular groove.

[0011] Furthermore, the fixing assembly includes a sliding ring slidably connected to the inner wall of the main body, the top of the sliding ring is fixedly connected to the arc plate, the inner wall of the arc plate is rotatably connected to the rotating plate, and the interior of the rotating plate is rotatably connected to the rotating shaft; Wherein, the side wall of the rotating shaft is fixedly connected to the inner wall of the arc plate.

[0012] Furthermore, the extrusion assembly includes a sliding plate fixedly connected to the end of the spring 2 away from the arc-shaped plate, and the outer surface of the sliding plate is slidably connected to the extrusion block 2. The inner wall of the extrusion block 2 is provided with a placement groove; The side walls of the two springs 2 are fixedly connected to the inner wall of the arc plate, and the end of the rotating shaft away from the arc plate contacts the side wall of the extrusion block 2.

[0013] Furthermore, the pushing assembly includes a plurality of return springs fixedly connected to the side wall of the placement slot, the ends of the plurality of return springs away from the rotating plate are fixedly connected to an extrusion strip, and the side of the extrusion strip close to the return spring is fixedly connected to an auxiliary plate; Wherein, the side wall of the auxiliary plate is slidably connected to the side wall of the placement groove.

[0014] The present invention has the following beneficial effects: 1. In the present invention, during the movement of the connecting ring, the arc plate will be pushed to slide downward on the inner wall of the main body. During the sliding of the arc plate, its bottom will push the movable ring to move downward and apply thrust to the elastic cylinder to shrink the elastic cylinder. At the same time, during the downward sliding of the arc plate, the two arc plates will gradually close. During the closing of the two arc plates, thrust will be applied to the cables inside the two arc plates so that the excess cables inside the main body will be discharged outward through the auxiliary cylinder, thereby causing the arc plate to squeeze the internal cables to keep them vertical, thereby reducing the situation in which, during the process in which the connecting ring is connected to the main body and moves toward the inside of the main body, part of the cables are not discharged outward through the auxiliary cylinder under the push of the connecting ring due to their softness and are accumulated inside the main body, thereby improving the efficiency of cable connection.

[0015] 2. In the present invention, during the downward sliding of the lifting plate, the swing plate will be pushed to slide inside the rectangular groove toward the center of the main body. During the sliding of the swing plate, the push plate will be pushed to slide inside the rectangular groove toward the center of the main body, so that part of the rectangular groove will contact the outer surface of the cable through the moving ring. Therefore, in the process of the arc plate pushing the lifting plate to be parallel to the top of the moving ring and continuing to move downward, the push plate will drive the cable to move to the outside of the auxiliary cylinder through the auxiliary cylinder, thereby reducing the situation in which part of the cable is stuck in the auxiliary cylinder and cannot move outward due to the push of the arc plate during the process of the two arc plates moving downward and merging, and further improving the overall quality of the cable connection.

[0016] 3. In the present invention, during the process of the rotating plate sliding toward the inside of the curved plate, the connecting ring will push the curved plate to slide downward after the rotating plate enters the inside of the curved plate, and while the rotating plate slides toward the inside of the curved plate, it will drive its other end to swing upward around the rotating axis. During the swinging of the rotating plate, it will push the sliding plate to pull the spring 2 to extend, thereby pushing the extrusion block 2 to extend toward the direction of the cable. After that, when the curved plate continues to move downward, the extrusion block 2 will first contact the connection port at the bottom of the connecting ring and then move downward, and then contact the connection between the cable and the connecting ring, thereby reducing the situation where the connection is unstable due to the pulling of the cable by the pushing plate in the process of the pushing plate driving the cable to move downward, thereby ensuring the quality of the cable connection.

[0017] 4. In the present invention, the second extrusion block will contact the connection at the bottom of the connecting ring, so that the extrusion strip will contact the connection, so that the extrusion strip applies a thrust to the reset spring to cause it to contract, and then the extrusion strip moves toward the inside of the placement groove. In the process of the movement of the extrusion strip, the auxiliary plate will be driven to slide inside the placement groove. In the process of the arc plate continuing to slide downward, the second extrusion block will pass the connection at the bottom of the connecting ring and contact the connection of the cable. After that, after the extrusion strip is separated from the bottom of the connecting ring, the extrusion strip will be pushed to reset by the reset spring and then reset. The extrusion strip will drive the auxiliary plate to reset, thereby squeezing the connection between the bottom of the connecting ring and the cable, thereby reducing the dispersion of the cable after the extrusion block 2 squeezes the cable connection, and further improving the efficiency of cable connection.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

After the cable is connected to the bottom of the connecting ring 101, the end not connected to the connecting ring 101 is pulled out from the auxiliary tube 113 to the outside after passing through the interior of the main body 1, and then the outer surface of the connecting ring 101 is connected to the inner wall of the main body 1.

[0030] The fixing assembly 22 includes a sliding ring 221 slidably connected to the inner wall of the main body 1. The top of the sliding ring 221 is fixedly connected to an arc plate 222.

Among them, the side wall of the rotating shaft 224 is fixedly connected to the inner wall of the arc plate 222. During the sliding of the swing plate 212, the pushing plate 213 will be pushed to slide toward the center of the main body 1 inside the rectangular groove 123, so that part of the rectangular groove 123 passes through the moving ring 122 and contacts the outer surface of the cable, so that the arc plate 222 pushes the lifting plate 211 to be parallel to the top of the moving ring 122 and continues to move downward.

[0031] The extrusion assembly 31 includes a sliding plate 312 fixedly connected to the end of the second spring 311 away from the arc-shaped plate 222. The outer surface of the sliding plate 312 is slidably connected to the second extrusion block 313. The inner wall of the second extrusion block 313 is provided with a placement groove 314. Among them, the side walls of the two springs 2311 are fixedly connected to the inner wall of the arc plate 222, and the end of the rotating shaft 224 away from the arc plate 222 contacts the side wall of the extrusion block 2313. When the auxiliary plate 323 is swung by the rotating plate 223 to pull the spring 2311 to extend, after the auxiliary plate 323 pulls the spring 2311 to extend, the extrusion block 2313 will contact the connection at the bottom of the connecting ring 101 so that the extrusion strip 322 contacts the connection.

[0032] The pushing assembly 32 includes a plurality of return springs 321 fixedly connected to the side wall of the placement slot 314. The ends of the return springs 321 away from the rotating plate 223 are fixedly connected to the extrusion strips 322. The side of the extrusion strips 322 close to the return springs 321 is fixedly connected to the auxiliary plate 323. Among them, the side wall of the auxiliary plate 323 is slidably connected to the side wall of the placement groove 314. During the movement of the extrusion bar 322, the auxiliary plate 323 will be driven to slide inside the placement groove 314. During the process of the arc plate 222 continuing to slide downward, the extrusion block 2 313 will pass through the connection at the bottom of the connecting ring 101 and then contact the connection of the cable. After that, after the extrusion bar 322 is separated from the bottom of the connecting ring 101, the extrusion bar 322 will be pushed to reset by the reset spring 321.

[0033] When in use, first connect the cable to the bottom of the connecting ring 101, then pull the end not connected to the connecting ring 101 through the interior of the main body 1 and out of the auxiliary tube 113, and then connect the outer surface of the connecting ring 101 to the inner wall of the main body 1. During the connection between the connecting ring 101 and the main body 1, the bottom of the connecting ring 101 will gradually move toward the inside of the main body 1. During the movement of the connecting ring 101, it will push the arc plate 222 to slide downward on the inner wall of the main body 1. During the sliding of the arc plate 222, its bottom will push the moving ring 122 to move downward, exerting a thrust on the elastic tube 121 to make the elastic tube 121 21 contracts, and at the same time, in the process of the arc plate 222 sliding downward, the two arc plates 222 will gradually close. In the process of the two arc plates 222 closing, a thrust will be applied to the cables inside the main body 1 so that the excess cables inside the main body 1 are discharged outward through the auxiliary cylinder 113, so that the arc plate 222 squeezes the internal cables to keep them vertical, thereby reducing the situation in which, during the process of the connecting ring 101 being connected to the main body 1 and moving toward the inside of the main body 1, part of the cables are not discharged outward through the auxiliary cylinder 113 under the push of the connecting ring 101 due to their softness, and are accumulated inside the main body 1, thereby improving the efficiency of cable connection.

[0034] As the curved plate 222 slides downward on the inner wall of the main body 1, it first contacts the top of the lifting plate 211, thereby pushing the lifting plate 211 to slide downward in the rectangular groove 123. As the lifting plate 211 slides downward, it pushes the swing plate 212 to slide inside the rectangular groove 123 at the center of the main body 1. As the swing plate 212 slides, it pushes the push plate 213 to slide inside the rectangular groove 123 toward the center of the main body 1, so that part of the rectangular groove 123 contacts the outer surface of the cable through the moving ring 122. As the curved plate 222 pushes the lifting plate 211 to be parallel to the top of the moving ring 122 and continues to move downward, the push plate 213 drives the cable to move through the auxiliary cylinder 113 to the outside of the auxiliary cylinder 113, thereby reducing the situation where some cables are stuck in the auxiliary cylinder 113 and cannot move outward due to the push of the curved plate 222 during the process of the two curved plates 222 moving downward and merging, thereby further improving the overall quality of the cable connection.

[0035] As the connecting ring 101 moves downward, it first contacts the protruding portion of the rotating plate 223, thereby pushing the protruding portion of the rotating plate 223 to slide inside the arc plate 222. As the rotating plate 223 slides toward the inside of the arc plate 222, the connecting ring 101 pushes the arc plate 222 to slide downward after the rotating plate 223 enters the inside of the arc plate 222. As the rotating plate 223 slides toward the inside of the arc plate 222, it drives the other end thereof to swing upward around the rotating shaft 224. As the rotating plate 223 swings During the process, the sliding plate 312 will be pushed to pull the spring 2 311 to extend, thereby pushing the extrusion block 2 313 to extend toward the cable direction. Then, when the arc plate 222 continues to move downward, the extrusion block 2 313 will first contact the connection port at the bottom of the connecting ring 101 and then move downward, and then contact the connection between the cable and the connecting ring 101, reducing the possibility of unstable connection at the connection due to the pulling of the cable by the pushing plate 213 in the process of the pushing plate 213 driving the cable to move downward, thereby ensuring the quality of the cable connection.

[0036] When the auxiliary plate 323 is swung by the rotating plate 223 and the spring 211 is extended, the auxiliary plate 323 pulls the spring 211 to extend, and the extrusion block 213 contacts the connection at the bottom of the connecting ring 101, so that the extrusion bar 322 contacts the connection, so that the extrusion bar 322 applies a thrust to the return spring 321 to make it contract, and then the extrusion bar 322 moves toward the inside of the placement groove 314. During the movement of the extrusion bar 322, the auxiliary plate 323 is driven to slide inside the placement groove 314. During the downward sliding process, the second squeezing block 313 passes the connection at the bottom of the connecting ring 101 and contacts the connection of the cable. After that, the squeezing bar 322 is separated from the bottom of the connecting ring 101 and is reset by the reset spring 321. Then, the squeezing bar 322 drives the auxiliary plate 323 to reset, thereby squeezing the connection between the bottom of the connecting ring 101 and the cable. This reduces the dispersion of the cable caused by the squeezing of the cable connection by the second squeezing block 313, and further improves the efficiency of cable connection.
