Description

Technical Field

[0001] The invention belongs to the technical field of cable connectors, in particular to a cable connector and a cable. Background Art

[0002] Cable connectors are devices used to connect cables and ensure stable transmission of power or signals. They are widely used in the fields of electricity, communications, automobiles, aerospace, etc. Their main functions include connecting cables, transmitting power or signals, simplifying installation and maintenance, providing protection, ensuring electrical performance and standardized interfaces.

[0003] When connecting a cable connector to a cable, the outer insulation of the cable must first be carefully removed to expose the conductive wires within. The exposed wires must then be inserted into the corresponding terminals of the connector. After this step, the operator should press or push the latch on the connector until it engages the cable's slot, locking the connector and cable securely and ensuring a stable connection.

[0004] However, these snap-on connectors often lose their initial elasticity due to material fatigue after frequent plugging and unplugging or prolonged use. This reduced elasticity significantly weakens the snap-on locking mechanism, potentially leading to unstable connections and even the risk of accidental disconnection. Furthermore, cable connectors with snap-on locking mechanisms often exhibit poor sealing properties, making them difficult to meet in demanding environments requiring high levels of waterproofing and dustproofing, thus limiting their applicability in certain applications.

[0005] To this end, the present invention provides a cable connector and a cable. Summary of the Invention

[0015] The release assembly includes a pull ring, a moving rod and a pull rope. The moving rod is elastically installed inside the control ring. The pull ring is located on one side of the control ring and is fixedly connected to one end of the moving rod. One end of the pull rope is fixedly connected to the card block, and the other end of the pull rope is fixedly connected to the moving rod.

[0016] The sensor module is used to collect the connection status of the female head and the male head. The signal processing module is connected to the sensor module and is used to process the connection status information of the female head and the male head collected by the sensor module and generate a corresponding status signal. The wireless communication module is connected to the signal processing module and is used to send the received status signal to the external monitoring terminal.

[0017] The male head is provided with a sealing block with a cavity, and the female head is provided with a sealing groove for inserting the sealing block.

[0019] The inside of the push rod is connected to a reciprocating screw rod through a thread, and the second transmission gear is fixedly installed on the end of the reciprocating screw rod away from the push rod. The transmission cylinder is rotatably installed inside the moving ring, and the first transmission gear is rotatably installed inside the moving ring.

At this time, the slide rod will slide to the other end of the arc groove along with the positioning block until the block provided in the arc groove is plugged into the card slot provided on the slide rod. Since the sliding of the positioning block is restricted by the connecting rod, when the card block is plugged into the card slot, the rotation of the control ring will be restricted, thereby improving the stability of the connection between the male head and the female head.

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0036] like Figures 1 to 7 As shown, a cable connector according to an embodiment of the present invention includes a male connector 2 and a female connector 7;

[0037] A positioning groove 6 is provided on the male connector 2, and a plug 20 for inserting into the positioning groove 6 is elastically installed inside the female connector 7. There are multiple plugs 20.

[0038] The insertion rod 20 is installed inside the female head 7 through a return spring. The return spring can keep the insertion rod 20 inside the female head 7 at all times. When the male head 2 and the female head 7 are plugged in, the positioning groove 6 on the male head 2 is located directly below the insertion rod 20. At this time, by controlling multiple insertion rods 20 to slide into the positioning groove 6 at the same time, the preliminary connection between the male head 2 and the female head 7 can be completed.

[0039] A control ring 8 is rotatably mounted on the female head 7, a swivel 12 is fixedly mounted on the inner wall of the control ring 8, and an arc-shaped push block 21 for pushing the insertion rod 20 is fixedly mounted on the bottom end of the swivel 12. The number of the arc-shaped push blocks 21 is the same as the number of the insertion rods 20;

[0040] When the control ring 8 rotates, it can drive the rotating ring 12 to rotate synchronously. When the rotating ring 12 rotates, it can drive multiple arc-shaped push blocks 21 to rotate synchronously. The arc-shaped push block 21 is set to an arc-shaped surface at one end facing the insertion rod 20. Therefore, when the arc-shaped push block 21 is driven to rotate by the rotating ring 12, it will press one end of the insertion rod 20, and through the setting of the arc surface, the insertion rod 20 can be pushed toward the direction of the positioning groove 6.

[0041] Therefore, after the male connector 2 and the female connector 7 are plugged in, it is only necessary to rotate the control ring 8 clockwise so that the rotating ring 12 drives the multiple arc-shaped push blocks 21 to push the multiple insertion rods 20 at the same time to achieve the initial connection between the male connector 2 and the female connector 7.

[0042] The side wall of the control ring 8 is provided with an arc groove 16, in which a positioning block 11 is slidably installed. The male connector 2 is provided with a connecting rod 5 for plugging with the positioning block 11;

[0043] A square hole is provided at the end of the positioning block 11 away from the arc groove 16, and the end of the connecting rod 5 close to the positioning block 11 is also set as a square rod. Therefore, when the male head 2 and the female head 7 are plugged in, the square rod part set on the connecting rod 5 will be plugged into the square hole provided on the positioning block 11. At this time, the movement of the positioning block 11 will be connected with the male head 2, so when the control ring 8 drives the rotating ring 12 to rotate clockwise, the positioning block 11 will move from one end of the arc groove 16 to the other end.

[0044] A limit assembly is provided on the positioning block 11 to limit the rotation of the control ring 8;

[0045] When the male connector 2 and the female connector 7 are plugged in, the control ring 8 is rotated clockwise, so that the rotating ring 12 drives multiple arc-shaped push blocks 21 to push multiple insertion rods 20 at the same time. After the initial connection between the male connector 2 and the female connector 7, the current position of the control ring 8 is limited by the set limit component, so that the multiple insertion rods 20 can remain plugged in with the positioning groove 6, thereby improving the stability of the connection between the male connector 2 and the female connector 7.

[0046] The control ring 8 is provided with a release component for releasing the restriction of the control ring 8 by the limit component;

[0047] The restriction of the control ring 8 by the limiting component can be released by the releasing component, and can be used when the male connector 2 is separated from the female connector 7.

[0048] The female connector 7 is provided with a monitoring component, which includes a sensor module, a signal processing module and a wireless communication module.

[0049] As a preferred embodiment of the present invention, the limiting assembly includes a slide rod 15, a block 17 and a slot 30. The slide rod 15 is fixedly mounted on one end of the positioning block 11 facing the arc groove 16. The slot 30 is opened on the slide rod 15, and the block 17 is elastically mounted inside the arc groove 16.

[0050] The bottom of the clamping block 17 is connected to the inside of the control ring 8 via a pressure spring. The setting of the pressure spring can keep the clamping block 17 extending to the arc groove 16.

[0051] When the male head 2 and the female head 7 are plugged in, the control ring 8 drives the rotating ring 12 to rotate clockwise. At this time, the multiple arc-shaped push blocks 21 will simultaneously press the multiple insertion rods 20, so that the multiple insertion rods 20 slide into the inside of the positioning groove 6. At the same time, the positioning block 11 will move to the other end of the arc groove 16 under the action of the connecting rod 5. At this time, the slide rod 15 will slide to the other end of the arc groove 16 along with the positioning block 11 until the block 17 provided in the arc groove 16 is plugged into the card slot 30 provided on the slide rod 15. Since the sliding of the positioning block 11 is restricted by the connecting rod 5, when the block 17 is plugged into the card slot 30, the rotation of the control ring 8 will be restricted, thereby improving the stability of the connection between the male head 2 and the female head 7.

[0052] As a preferred embodiment of the present invention, the release assembly includes a pull ring 9, a moving rod 19 and a pull rope 18. The moving rod 19 is elastically installed inside the control ring 8. The pull ring 9 is located on one side of the control ring 8 and is fixedly connected to one end of the moving rod 19. One end of the pull rope 18 is fixedly connected to the block 17, and the other end of the pull rope 18 is fixedly connected to the moving rod 19.

[0053] The moving rod 19 is connected to the control ring 8 via a connecting spring. The provided connecting spring can drive the pull ring 9 to always maintain a state of being in contact with the control ring 8.

[0054] Therefore, when the pull ring 9 is in contact with the control ring 8, the pull rope 18 will not pull the card block 17, so the card block 17 will still be located inside the arc groove 16. After the male head 2 and the female head 7 are plugged in, the control ring 8 drives the swivel 12 to rotate clockwise, so that the multiple arc-shaped push blocks 21 press the multiple insertion rods 20 into the positioning groove 6. At the same time, when the card block 17 is engaged with the card groove 30, it is only necessary to pull the pull ring 9 away from the control ring 8, and the pull rope 18 can be driven by the moving rod 19 to pull the card block 17 and pull the card block 17 out of the inside of the card groove 30. At this time, the control ring 8 can be rotated counterclockwise to release the multiple arc-shaped push blocks 21 from the pressure on the multiple insertion rods 20. The multiple insertion rods 20 are pulled out from the inside of the positioning groove 6 under the action of the reset spring, and the male head 2 and the female head 7 can be separated.

[0055] As a preferred embodiment of the present invention, the sensor module is used to collect the connection status of the female head 7 and the male head 2. The signal processing module is connected to the sensor module and is used to process the connection status information of the female head 7 and the male head 2 collected by the sensor module and generate a corresponding status signal. The wireless communication module is connected to the signal processing module and is used to send the received status signal to an external monitoring terminal.

[0056] The sensor module collects the connection status information of the male connector 2 and the female connector 7 in real time, such as temperature, humidity, vibration, stress, current and voltage, and transmits the data to the signal processing module. The signal processing module processes the collected data, converts the analog signal into a digital signal through the analog-to-digital conversion unit, and the data processing unit analyzes and judges it to generate a status signal. When an abnormality is detected (such as excessive temperature, abnormal vibration or current and voltage out of range), the signal processing module triggers the alarm module to issue an alarm signal and sends the status signal to the external monitoring terminal through the wireless communication module. The wireless communication module adopts low-power technology (such as LoRa, ZigBee or NB-IoT) and supports real-time transmission and scheduled transmission. The alarm module reminds the staff through sound, light, vibration or remote notification, and prevents safety accidents caused by connection failures by real-time monitoring of the connection status of the male connector 2 and the female connector 7.

[0057] As a preferred embodiment of the present invention, a sealing block 14 is provided in a cavity on the male head 2, and a sealing groove 10 for inserting the sealing block 14 is provided on the female head 7. The sealing block 14 is elastically arranged and can be deformed under force.

[0058] When the male connector 2 is plugged into the female connector 7, the sealing block 14 provided on the male connector 2 will be inserted into the sealing groove 10 provided on the female connector 7, thereby improving the sealing effect of the connection between the male connector 2 and the female connector 7, preventing dust and moisture from entering, reducing the risk of corrosion and short circuit, and being suitable for harsh conditions such as humidity and dust.

[0059] As a preferred embodiment of the present invention, a movable ring 3 is slidably installed on the male head 2, and a press-inflating pump 29 is provided inside the movable ring 3. A one-way air pipe 13 is connected to the press-inflating pump 29, and the other end of the one-way air pipe 13 is connected to the sealing block 14. A push rod 28 for pushing the press-inflating pump 29 is slidably installed inside the movable ring 3.

[0060] By controlling the push rod 28 to move toward the pressing and inflating pump 29 and squeezing the pressing and inflating pump 29, the pressing and inflating pump 29 will discharge the gas inside and deform at the same time. When the push rod 28 moves away from the pressing and inflating pump 29, the pressing and inflating pump 29 releases its elastic potential energy to suck the external air into the inside of the pressing and inflating pump 29. When the push rod 28 squeezes the pressing and inflating pump 29 again and deforms it, the gas inside the pressing and inflating pump 29 will be transported to the inside of the sealing block 14 through the one-way air pipe 13. After the male head 2 and the female head 7 are plugged in, the sealing block 14 is inserted into the sealing groove 10. By reciprocatingly squeezing the pressing and inflating pump 29, the gas is transported to the inside of the sealing block 14 through the one-way air pipe 13, causing the sealing block 14 to expand and further fit the sealing groove 10, thereby improving the sealing effect between the male head 2 and the female head 7.

[0061] As a preferred embodiment of the present invention, a spiral groove 24 is provided on the inner wall of the transmission cylinder 22, one end of the connecting rod 5 extends to the interior of the transmission cylinder 22, and a guide block 23 is fixedly installed on the outer wall of the connecting rod 5, and one end of the guide block 23 extends to the interior of the spiral groove 24. The interior of the push rod 28 is connected to a reciprocating screw rod 27 through a thread, and the end of the reciprocating screw rod 27 away from the push rod 28 is fixedly installed with a second transmission gear 26. The transmission cylinder 22 is rotatably installed inside the moving ring 3, and the first transmission gear 25 is rotatably installed inside the moving ring 3. The first transmission gear 25 is engaged with the second transmission gear 26. The push ring 4 is threadedly connected to the male head 2, and the side wall of the push ring 4 is fitted with the side wall of the moving ring 3 through the pressure rod.

[0062] When the male head 2 and the female head 7 are plugged in, by rotating the push ring 4, the movable ring 3 will be driven to slide toward the female head 7 under the action of the pressure rod, and at the same time, the transmission cylinder 22 will also slide on the outer wall of the connecting rod 5. Since the rotation of the connecting rod 5 is restricted by the positioning block 11, the transmission cylinder 22 will slide along the outer wall of the connecting rod 5 under the drive of the movable ring 3. At the same time, through the cooperation of the guide block 23 and the spiral groove 24, the transmission cylinder 22 will rotate inside the movable ring 3 and drive the first transmission gear 25 to rotate. At this time, the second transmission gear 26 will drive the reciprocating screw 27 to rotate, so that the push rod 28 slides back and forth inside the movable ring 3 and reciprocates to squeeze the pressing air pump 29.

[0063] The number of teeth of the first transmission gear 25 is greater than that of the second transmission gear 26. The number of revolutions of the reciprocating screw 27 can be increased through differential speed, thereby ensuring the number of times the air pump 29 is squeezed and pressed, and ensuring the sealing effect between the male head 2 and the female head 7.

[0064] A cable includes the above-mentioned cable connector and a cable body 1, wherein the cable body 1 is composed of a conductor, a shielding layer, a sheath layer and a self-repairing layer. The shielding layer is arranged on the outside of the conductor to shield electromagnetic interference. The sheath layer is arranged on the shielding layer to protect the cable body 1. The self-repairing layer is arranged between the shielding layer and the sheath layer to repair the cable body 1 when it is damaged.

[0065] The self-repairing layer is made of a nano-composite shape memory polymer material. The nano-composite shape memory polymer material includes a shape memory polymer matrix and nanoparticles dispersed in the matrix. The nanoparticles are carbon nanotubes or graphene.

[0066] Working principle: When the male head 2 and the female head 7 are plugged in, the control ring 8 drives the swivel 12 to rotate clockwise. At this time, multiple arc-shaped push blocks 21 will simultaneously press multiple insertion rods 20, causing multiple insertion rods 20 to slide into the inside of the positioning groove 6. At the same time, the positioning block 11 will move to the other end of the arc groove 16 under the action of the connecting rod 5. At this time, the slide rod 15 will slide to the other end of the arc groove 16 along with the positioning block 11 until the block 17 provided in the arc groove 16 is plugged into the card slot 30 provided on the slide rod 15. Since the sliding of the positioning block 11 is restricted by the connecting rod 5, when the block 17 is plugged into the card slot 30, the rotation of the control ring 8 will be restricted, thereby improving the stability of the connection between the male head 2 and the female head 7.

[0067] When the male head 2 is plugged into the female head 7, the pushing ring 4 is rotated, and the moving ring 3 is driven to slide toward the female head 7 under the action of the pressure rod. At the same time, the transmission cylinder 22 will also slide on the outer wall of the connecting rod 5. Since the rotation of the connecting rod 5 is restricted by the positioning block 11, the transmission cylinder 22 will slide along the outer wall of the connecting rod 5 under the drive of the moving ring 3. At the same time, through the cooperation of the guide block 23 and the spiral groove 24, the transmission cylinder 22 will rotate inside the moving ring 3 and drive the first transmission gear 25 to rotate. At this time, the second transmission gear 26 will drive the reciprocating screw 27 to rotate, so that the push rod 28 slides back and forth inside the moving ring 3, and reciprocates to squeeze the pressing air pump 29, and transports the gas to the inside of the sealing block 14 through the one-way air pipe 13, so that the sealing block 14 expands and further fits the sealing groove 10, thereby improving the sealing effect between the male head 2 and the female head 7, effectively preventing dust and moisture from entering, reducing the risk of corrosion and short circuit, and suitable for harsh conditions such as humidity and dust.
