Description

Technical Field

[0001] This invention belongs to the field of connector technology, and specifically relates to a communication cable connector structure. Background Technology

[0002] Communication cable connectors are key components used to achieve signal transmission between cables or between cables and equipment, and are widely used in communications, networking, broadcasting, and industrial control. In existing technology, common cable connectors mainly consist of a plug and a socket. The plug end has a ferrule, and the socket end has a matching tube or socket. Electrical contact or optical signal coupling is achieved by inserting the ferrule into the tube. When the connector is repeatedly plugged and unplugged, the contact surfaces between the ferrule and the tube experience gradual mechanical wear due to continuous compression and relative sliding. This wear is particularly noticeable at the front end of the ferrule or the edge of the tube opening, where scratches, plating peeling, or localized plastic deformation often appear first, leading to a gradual increase in the mating clearance and a decrease in the original interference fit. As the wear deepens, the normal pressure between the two decreases significantly, and the frictional force can no longer maintain the initial preload level. Under slight external force, the connector is prone to axial loosening or even complete detachment. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a communication cable connector structure that can improve the wear resistance and anti-loosening capability in frequent plugging and unplugging scenarios.

[0004] To achieve the above objectives, the present invention provides the following technical solution: This invention discloses a communication cable connector structure, including a plug end, a core connected to the plug end, a socket end, and a tube connected to the socket end. The core and tube correspond to each other, and the tube is installed in a socket hole on the inner side of the socket end. The tube includes multiple arc-shaped inserts evenly spaced along the circumference. Adjacent arc-shaped inserts are connected by elastic connecting pieces. An elastic washer is fixedly connected to the outer side of the arc-shaped inserts. A radial preload device is installed on the outer side of the elastic washer. An axial sliding hole is opened on the end face of the socket end. A slide rod is slidably arranged in the axial sliding hole. The inner end of the slide rod is connected to the socket end through a first support spring. The other end of the slide rod extends out from the end face of the socket end. The slide rod drives the radial preload device to act on the tube. When the plug end and the socket end are engaged, the end face of the plug end can act on the slide rod.

[0005] Furthermore, the radial preloading device includes a fixed ring, fan-shaped petals, a first pin, a second pin, a third pin, a connecting rod, a turntable, a rotating cylinder, a gear ring, and a gear. The fixed ring is fixedly installed on the inner side of the socket end. One end of the fan-shaped petals is hinged to the fixed ring through the first pin. Multiple sets of fan-shaped petals are evenly spaced along the circumference on one side of the fixed ring. The fan-shaped petals include an inner arc surface and an outer arc surface. The inner arc surface of one set of fan-shaped petals mates with the outer arc surface of the adjacent fan-shaped petals. The other end of the fan-shaped petals is hinged to one end of the connecting rod through the second pin. The other end of the connecting rod is hinged to the turntable through the third pin. The turntable is coaxially fixedly connected to the rotating cylinder. A gear ring is fixed on the outer side of the rotating cylinder. The gear ring meshes with the gear. The gear is rotatably installed in a rotating groove opened on the inner side of the socket end. The inner hole of the gear is threadedly connected to the slide rod.

[0006] Furthermore, the cannula is formed within a central hole created by multiple fan-shaped lobes. When the fan-shaped lobes deflect, they can press the arc-shaped insert of the cannula tightly against the insert core.

[0007] Furthermore, the arc-shaped insert is connected to a first cable, the socket end has a first channel for the first cable to pass through, the plug is connected to a second cable, and the plug end has a second channel for the second cable to pass through.

[0008] Furthermore, the ferrule includes a main core segment and a secondary core segment coaxially connected to the main core segment. The diameter of the secondary core segment is smaller than that of the main core segment, thus forming a step between the main core segment and the secondary core segment.

[0009] Furthermore, a radial sliding hole is formed on the surface of the socket end, and a drive block is slidably and sealed at the outer end of the radial sliding hole. The outer end of the drive block forms a wedge-shaped structure. The inner end of the drive block is connected to one side of the support frame through a second support spring. The other side of the support frame is connected to the locking pin through a first elastic tension spring. The locking pin is slidably and sealed at the inner end of the radial sliding hole. The locking pin can cooperate with the step. A hydraulic cavity is formed between the locking pin and the drive block. The hydraulic cavity is filled with hydraulic oil. A locking component that cooperates with the drive block is installed on the plug end.

[0010] Furthermore, the engaging component includes a sliding sleeve that is slidably sleeved on the outside of the plug end. The sliding sleeve is connected to the base via a second elastic tension spring. The base is fixed on the outside of the plug end. The inner wall of the sliding sleeve is provided with a guide groove, a flat groove, and a retaining groove. The guide groove extends inward from the outer end face of the sliding sleeve and connects to one end of the flat groove. The flat groove extends along the circumference of the sliding sleeve. The other end of the flat groove is connected to the retaining groove, which extends toward the inner end face of the sliding sleeve.

[0011] Furthermore, the socket end includes a main seat and a secondary seat that can be detachably mounted on the end face of the main seat. A rotating groove is formed on the main seat, and the secondary seat can close the rotating groove. A radial sliding hole is formed on the secondary seat. The radial sliding hole cooperates with the locking post and the driving block through an inner hole section and an outer hole section, respectively. The diameter of the inner hole section is smaller than the diameter of the outer hole section.

[0012] The beneficial effects of this invention are as follows: This invention discloses a communication cable connector structure. By designing a tube composed of multiple arc-shaped inserts, when the connector's plug and socket ends mate, the end face of the plug acts on a sliding rod. The sliding rod drives a radial preload device to operate on the tube, causing the tube to radially press the ferrule, thus achieving a connection. Compared to traditional insertion and removal methods that rely solely on friction, the friction force of this invention can change according to the insertion depth between the ferrule and the tube. This reduces the continuous impact of friction between the ferrule and tube during insertion and removal, thereby improving wear resistance and anti-loosening capabilities in frequent insertion and removal scenarios.

Detailed Implementation

[0015] like Figures 1-7As shown, the present invention discloses a communication cable connector structure, including a plug end 1, a core 2 connected to the plug end 1, a socket end 3, and a tube 4 connected to the socket end 3. The core 2 and the tube 4 correspond to each other. The end faces of the plug end 1 and the socket end 3 are both flat. When the end face of the plug end 1 and the end face of the socket end 3 are engaged, the core 2 and the tube 4 engage to connect the cable.

[0016] The insertion tube 4 is installed inside the socket 5 on the inner side of the socket end 3. The insertion tube 4 includes multiple arc-shaped inserts 6 evenly spaced along the circumference. The arc-shaped inserts 6 can move radially along the socket 5 to change the degree of radial compression of the insertion tube 4. Adjacent arc-shaped inserts 6 are connected by elastic connecting pieces 7, which can be made of rubber or elastic alloy material. An elastic gasket 8 is fixedly connected to the outer side of the arc-shaped insert 6. A radial pre-compression device 9 is installed on the outer side of the elastic gasket 8. The elastic gasket 8 is made of rubber material and can play a role in elastic compression under the action of the radial pre-compression device 9.

[0017] Furthermore, an axial sliding hole 10 is provided on the end face of the socket end 3 of the present invention. The axial sliding hole 10 is a straight hole of the same diameter, extending along the axial direction of the socket end 3. A sliding rod 11 is slidably disposed in the axial sliding hole 10. The inner end of the sliding rod 11 is connected to the socket end 3 through a first support spring 12. The other end of the sliding rod 11 extends from the end face of the socket end 3. The sliding rod 11 drives the radial pre-compression device 9 to act on the insertion tube 4. When the plug end 1 and the socket end 3 are engaged, the end face of the plug end 1 can act on the sliding rod 11. The sliding rod 11 drives the radial pre-compression device 9 to act on the insertion tube 4, so that the insertion tube 4 presses the plug core 2 tightly from the radial direction, thereby achieving the connection function. Compared with the traditional insertion and removal method that relies solely on friction, the friction force of the present invention can change according to the insertion depth between the plug core 2 and the insertion tube 4, which can reduce the continuous impact of friction between the plug core 2 and the insertion tube 4 during insertion and removal, thereby improving the wear resistance and anti-loosening ability in frequent insertion and removal scenarios.

[0018] In this embodiment, the radial preloading device 9 includes a fixed ring 13, fan-shaped petals 14, a first pin 15, a second pin 16, a third pin 17, a connecting rod 18, a turntable 19, a rotating cylinder 20, a gear ring 21, and a gear 22. The fixed ring 13 is fixedly installed inside the socket end 3. One end of the fan-shaped petals 14 is hinged to the fixed ring 13 through the first pin 15. The five sets of fan-shaped petals 14 are arranged in the same way, and the five sets of fan-shaped petals 14 are evenly spaced along the circumference on one side of the fixed ring 13. The fan-shaped petals 14 have three arc surfaces. In addition to the basic arc surface, the fan-shaped petals 14 also include an inner arc surface and an outer arc surface. The inner arc surface of one set of fan-shaped petals 14 cooperates with the outer arc surface of the adjacent fan-shaped petals 14. After the fan-shaped petals 14 rotate, the five sets of fan-shaped petals 14 can press the insertion tube 4 radially.

[0019] The specific connection method is as follows: the other end of the fan-shaped petal 14 is hinged to one end of the connecting rod 18 through the second pin 16, and the other end of the connecting rod 18 is hinged to the turntable 19 through the third pin 17. The turntable 19 is coaxially fixedly connected to the rotating cylinder 20. A gear ring 21 is fixed on the outside of the rotating cylinder 20. The gear ring 21 meshes with the gear 22. The gear 22 is rotatably installed in the rotating groove opened on the inside of the socket end 3. The inner hole of the gear 22 is threadedly connected to the slide rod 11. When the slide rod 11 retracts inward under the action of the plug end 1, the slide rod 11 moves and compresses the first support spring 12. Under the action of the thread, the slide rod 11 can drive the gear 22 to rotate. The gear 22 drives the rotating cylinder 20 that meshes with it to rotate. The rotating cylinder 20 drives the turntable 19 to rotate. The turntable 19 drives the five fan-shaped petals 14 to rotate synchronously through the connecting rod 18, realizing the synchronous radial pressing effect on the outside of the insertion tube 4.

[0020] In this embodiment, the insertion tube 4 is formed within the central hole formed by multiple fan-shaped petals 14. When the fan-shaped petals 14 deflect, they can press the arc-shaped insert 6 of the insertion tube 4 against the core 2, improving the connection effect. The arc-shaped insert 6 is connected to a first cable 23, and a first channel 24 for the first cable 23 to pass through is opened in the socket end 3. The core 2 is connected to a second cable 25, and a second channel 26 for the second cable 25 to pass through is opened in the plug end 1.

[0021] In this embodiment, the insert 2 includes a main core segment 27 and a secondary core segment 28 coaxially connected to the main core segment 27. The diameter of the secondary core segment 28 is smaller than the diameter of the main core segment 27, so that a step 29 is formed between the main core segment 27 and the secondary core segment 28.

[0022] In this embodiment, a radial sliding hole 30 is provided on the surface of the socket end 3. A drive block 31 is slidably and sealed at the outer end of the radial sliding hole 30. The outer end of the drive block 31 forms a wedge-shaped structure. The inner end of the drive block 31 is connected to one side of the support frame 36 through a second support spring 32. The other side of the support frame 36 is connected to the locking post 34 through a first elastic tension spring 33. The locking post 34 is slidably and sealed at the inner end of the radial sliding hole 30. The locking post 34 can cooperate with the step 29 to lock the plug 2 and prevent it from falling off. A hydraulic cavity 35 is formed between the locking post 34 and the drive block 31. The hydraulic cavity 35 is filled with hydraulic oil. A locking member that cooperates with the drive block 31 is installed on the plug end 1.

[0023] In this embodiment, the engaging component includes a sliding sleeve 37 that is slidably sleeved on the outside of the plug end 1. The sliding sleeve 37 is connected to the base 39 via a second elastic tension spring 38. The base 39 is fixed on the outside of the plug end 1. The inner wall of the sliding sleeve 37 is provided with a guide groove 40, a flat groove 41, and a locking groove 42. The guide groove 40 extends inward from the outer end face of the sliding sleeve 37 and connects to one end of the flat groove 41. The flat groove 41 extends along the circumference of the sliding sleeve 37. The other end of the flat groove 41 is connected to the locking groove 42. The locking groove 42 extends toward the inner end face of the sliding sleeve 37. When the sliding sleeve 37 is slid, the driving block 31 can sequentially enter the locking groove 42 through the guide groove 40 and the flat groove 41, thereby locking the sliding sleeve 37 onto the outside of the socket end 3. The driving block 31 drives the locking pin 34 to move via hydraulic oil, thereby locking the locking pin 34 at the step 29 position to prevent it from falling off. When it is necessary to remove the sliding sleeve 37, rotate and move the sliding sleeve 37, and the drive block 31 slides out from the slot 42, the flat slot 41 and the guide slot 40 in sequence, which can achieve separation. Using the above method, the operation is more convenient.

[0024] In this embodiment, the socket end 3 includes a main seat 43 and a secondary seat 44 detachably mounted on the end face of the main seat 43. A rotating groove is formed on the main seat 43, and the secondary seat 44 can close the rotating groove. A radial sliding hole 30 is formed on the secondary seat 44. The radial sliding hole 30 cooperates with the locking post 34 and the driving block 31 through an inner hole section and an outer hole section, respectively. The diameter of the inner hole section is smaller than the diameter of the outer hole section. The main seat 43 and the secondary seat 44 are separated to facilitate the processing and cleaning of the rotating groove and the radial sliding hole 30.
