Their main function is to achieve rapid connection and disconnection between cables to ensure efficient transmission of electrical energy or signals. With the complexity of electrical equipment and the diversification of working environments, the reliability and safety requirements of cable connectors are increasing.

Although they can meet basic electrical connection requirements to a certain extent, it is difficult to monitor the connection status in real time and cannot promptly detect connection abnormalities caused by looseness, poor contact or external force. This problem is particularly prominent in harsh environments such as high vibration, high humidity or high temperature, which may cause electrical failures, equipment damage or even safety accidents.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0040] Reference Figures 1 to 3 The present invention provides an embodiment: a cable connector with a monitoring function, comprising a plug 1 and a socket 2, wherein a monitoring mechanism 3 is provided on the top of the plug 1 and the socket 2, and the monitoring mechanism 3 is used to monitor the connection status of the cable connector in real time and to provide timely feedback. A reinforcement mechanism 4 is provided on the outside of the plug 1 and the socket 2, and the reinforcement mechanism 4 is used to prevent the cable connector from being accidentally loosened or disconnected due to external force;

[0041] Reference Figure 5 , the plug 1 includes an outer shell 11. The outer shell 11 serves as the external protection structure of the plug 1 and is usually made of high-strength insulating material, which can effectively prevent the external environment from damaging the internal cable core 12. The inner part of the outer shell 11 is fixedly connected with a cable core 12. The cable core 12 is the core part of the cable and is responsible for transmitting electrical energy or signals. A docking joint 13 is provided at one end of the cable core 12. The design of the docking joint 13 enables the plug 1 to be quickly and stably connected to the socket 2. The inner thread of the outer shell 11 is connected with a threaded docking ring 14. The threaded docking ring 14 is fixed to the inner part of the outer shell 11 by a threaded connection, which not only enhances the structural strength of the plug 1, but also facilitates the docking and separation of the plug 1 and the socket 2;

[0042] Reference Figure 4 , the socket 2 includes an outer shell 21, and the outer shell 21 is made of the same material as the outer shell 11 to ensure the consistency of the overall structure. The outer side of the threaded docking ring 14 is threadedly connected to the inner side of the outer shell 21, and the inner wall of the outer shell 21 is fixedly connected with an insulating sleeve 22. The provision of the insulating sleeve 22 further enhances the safety performance of the socket 2 to prevent current leakage or short circuit. An inner core 23 is provided inside the insulating sleeve 22. The inner core 23 is the core part of the socket 2 and is responsible for electrical connection with the cable core 12 of the plug 1. One end of the inner core 23 is fixedly connected with a docking seat 24, and the docking seat 24 is adapted to the shape of the docking head 13. The design of the docking seat 24 is adapted to the docking head 13 to ensure that the plug 1 and the socket 2 can be accurately docked;

[0043] Reference Figure 3 , Figure 6 and Figure 8The monitoring mechanism 3 includes a feedback component 31 and a protection component 32. The feedback component 31 is arranged inside the housing 1 11 and the housing 2 21. The feedback component 31 is used to monitor the status of the cable connector in real time to ensure its normal operation. The protection component 32 is arranged outside the housing 1 11 and the housing 2 21. The protection component 32 protects the feedback component 31 from the external environment through the external structure.

[0044] The feedback component 31 includes a conductive ring 1 3101 and a conductive ring 2 3111. The conductive ring 1 3101 and the conductive ring 2 3111 are the core parts of the feedback component 31 and are responsible for the transmission and monitoring of the current. The conductive ring 1 3101 is arranged between the insulating sleeve 22 and the docking seat 24 and is connected to the inner core 23. The top of the conductive ring 1 3101 is fixedly connected with a plug plate 3102, and the top of the plug plate 3102 is electrically connected with a transmission plate 3103. The docking between the plug plate 3102 and the transmission plate 3103 allows the current inside the feedback component 31 to be transmitted to the inner core 23 to form a path. The top of the transmission plate 3103 is rotatably connected with a power connection plate 3104, and the other end of the power connection plate 3104 is electrically connected with a power connection post 3105. The power connection plate 3104 and the power connection post 3105 are used to transmit current. The bottom of the power connection post 3105 is fixedly connected with a circuit board 3106. The design of the circuit board 3106, the plug board 3102, the transmission board 3103, the power connection board 3104 and the power connection post 3105 enables the current to be stably transmitted to the inner core 23. Two terminal blocks 3107 are arranged on the top of the circuit board 3106. The tops of the two terminal blocks 3107 are both provided with wires 3108. The terminal blocks 3107 and the wires 3108 are used to transmit the current to the subsequent structure. The adjacent ends of the two wires 3108 are electrically connected with a shunt resistor 3109. The resistance value of the shunt resistor 3109 is relatively large, which is used to prevent the current flowing into the feedback component 31 from being too large and causing damage to the feedback component 31. An LED lamp 3110 is arranged on the top of the shunt resistor 3109. The LED lamp 3110 displays different brightness according to the current, so as to intuitively reflect the current state. When the cable connector is accidentally disconnected, since the resistance of the shunt resistor 3109 is much smaller than the open-circuit resistance, the current all passes through the feedback component 31, thereby significantly increasing the brightness of the LED lamp 3110. When the cable connector is connected normally, since the resistance of the shunt resistor 3109 is much larger than the path resistance, the current flowing to the feedback component 31 is reduced, thereby reducing the brightness of the LED lamp 3110, so that the state of the cable connector can be observed by the brightness of the LED lamp 3110.

[0045] The inner side of the second conductive ring 3111 is fixedly connected to the outer side of the cable core 12, so as to guide the current inside the cable core 12 outward. The top of the second conductive ring 3111 is fixedly connected to the spring 1 3112, and the top of the spring 1 3112 is fixedly connected to the movable plate 3113, which is used to guide the current inside the cable core 12 so that the current enters the feedback component 31. The outer side of the bottom of the movable plate 3113 is slidably connected to the top of the second conductive ring 3111, and then through the elastic action of the spring 1 3112, the movable plate 3113 can always remain in a certain position after the threaded docking ring 14 ends its movement, thereby ensuring accurate docking with subsequent structures. The inside of the threaded docking ring 14 is fixedly connected with a connecting post 3114, the bottom of the connecting post 3114 is snap-fitted with the top of the movable plate 3113, and the other end of the circuit board 3106 is snap-fitted with the top of the connecting post 3114, so that through the docking of the connecting post 3114 and the movable plate 3113, a part of the current passes through the cable core 12 into the circuit board 3106, thereby forming a complete path, so that the LED lamp 3110 can work normally.

[0046] The protection component 32 includes a protection shell 1 3201 and a protection shell 2 3202. The protection shell 1 3201 is fixedly connected to the outer wall of the outer shell 21, and the protection shell 2 3202 is fixedly connected to the outer wall of the threaded docking ring 14. The protection shell 1 3201 and the protection shell 2 3202 are responsible for protecting the feedback component 31 from the external environment. One end of the protection shell 2 3202 is rotatably connected to an insulating cover plate 3203. The design of the insulating cover plate 3203 further enhances the insulation performance of the protection component 32, and the insulating cover plate 3203 is provided with an opening that allows the light-emitting part of the LED lamp 3110 to pass through, thereby ensuring that the brightness of the LED lamp 3110 can be directly observed. The other end of the insulating cover plate 3203 is detachably connected to the top of the protective shell 1 3201. An arc-shaped positioning ring is provided on the outside of the protective shell 2 3202. The arc-shaped positioning ring is detachably connected to the outside of the protective shell 1 3201. Through the arc-shaped positioning ring, the protective shell 2 3202 can be accurately engaged with the protective shell 1 3201 after moving with the threaded docking ring 14.

[0047] Reference Figure 3 , Figure 7 and Fig. 9The reinforcement mechanism 4 includes a fixing ring 41, the inner side of which is fixedly connected to the outer wall of the outer shell 21. The fixing ring 41 enables the reinforcement mechanism 4 to form a whole with the cable connector so that the reinforcement performance of the reinforcement mechanism 4 can directly act on the cable connector body. A plurality of docking posts 1 42 are fixedly connected to the outer side of the fixing ring 41, and a plurality of docking posts 2 43 are fixedly connected to the outer side of the outer shell 11. The connection between the docking posts 1 42 and the docking posts 2 43 is reinforced to strengthen the connection between the plug 1 and the socket 2. A spherical head 44 is fixedly connected to the other end of the docking post 1 42, and the outer wall of the spherical head 44 is detachably connected to the inside of the docking post 2 43. The spherical head 44 enables the plug 1 and the socket 2 to be connected quickly and firmly. A snap-on assembly 45 is fixedly connected to the inside of the docking post 2 43.

[0048] The clamping assembly 45 includes a plurality of fixed cylinders 4501, the outer wall of which is fixedly connected to the interior of the docking column 43, and the fixed cylinder 4501 provides a mounting and movable foundation for the subsequent structure. The interior of the fixed cylinder 4501 is slidably connected with a sliding column 4503, and the outer side of the sliding column 4503 is slidably connected to the interior of the docking column 43, and the further docking of the docking column 42 and the docking column 43 is achieved by pulling the sliding column 4503. The outer wall of the sliding column 4503 is fixedly connected with a limiting plate 4504, and the outer wall of the limiting plate 4504 is slidably connected to the inner wall of the fixed cylinder 4501, and the limiting plate 4504 is used to limit the sliding range of the sliding column 4503 to prevent it from escaping from the fixed cylinder 4501. The outer side of the sliding column 4503 is sleeved with a second spring 4502, one end of the second spring 4502 is fixedly connected to the inner wall of the fixed cylinder 4501, and the other end of the second spring 4502 is fixedly connected to the top of the limit plate 4504. The second spring 4502 enables the sliding column 4503 to automatically reset when subjected to external force, thereby ensuring the stability and reliability of the clamping assembly 45. The adjacent ends of the plurality of sliding columns 4503 are all fixedly connected with a clamping ring 4505, and the adjacent sides of the plurality of clamping rings 4505 are clamped with the outer side of the rear end of the spherical head 44, and the clamping ring 4505 is in close contact with the outer wall of the rear end of the spherical head 44, forming a stable mechanical connection.

[0049] Working principle: When in use, first align the plug 1 with the socket 2, firmly insert the plug 1 into the socket 2, and then rotate the threaded docking ring 14 to connect the threaded docking ring 14 with the second housing 21, ensuring that the docking head 13 is in close contact with the docking seat 24 to form an electrical path. At the same time, the movement of the threaded docking ring 14 drives the second protective shell 3202 to move synchronously until it docks with the first protective shell 3201, and then rotate the circuit board 3106 so that the circuit board 3106 rotates along the transmission plate 3103 as the center and is clamped with the connecting pile 3114, so that the entire monitoring mechanism 3 forms a parallel structure with the cable connector path, and then rotate the insulating cover plate 3203 to close the first protective shell 3201 and the second protective shell 3202, so as to protect the internal feedback component 31. At this time, the current is mainly transmitted through the cable core 12 and the inner core 23, and a part of the current enters the circuit board 3106 through the conductive ring 2 3111 of the feedback component 31, and then passes through the circuit board 3106, the shunt resistor 3109, the LED lamp 3110, the power connection pile 3105, the transmission plate 3103 and the plug plate 3102 to form a path in the conductive ring 1 3101, so as to monitor the connection status of the cable connector without affecting the total current transmission of the entire cable connector. When the cable connector is connected normally, compared with the path resistance of the cable connector, the resistance of the shunt resistor 3109 is larger, the current flowing to the LED lamp 3110 is smaller, and the brightness of the LED lamp 3110 is lower; when the cable connector is accidentally disconnected, the resistance of the shunt resistor 3109 is much smaller than the circuit breaker resistance, the current passes through the feedback component 31, and the brightness of the LED lamp 3110 increases significantly, which intuitively indicates that the connection is abnormal, thereby realizing real-time monitoring of the connection status of the cable connector.

[0050] When the spherical head 44 is inserted into the interior of the docking column 43, the outer wall of the spherical head 44 will squeeze the clamping ring 4505, causing the sliding column 4503 to slide along the inner wall of the fixed tube 4501 and compress the spring 4502 at the same time. When the spherical head 44 is fully inserted, the elastic force of the spring 4502 pushes the sliding column 4503 to reset, causing the clamping ring 4505 to be in close contact with the outer wall of the spherical head 44 to form a stable mechanical connection. When it is necessary to separate the plug 1 and the socket 2, it is only necessary to apply a certain pulling force to the sliding column 4503 to separate the clamping ring 4505 from the spherical head 44, and then pull the plug 1 to make the spherical head 44 detach from the docking column 43 to complete the separation operation.

[0051] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
