[0045] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0046] In the context of the rapid development of information technology, connectors, as an indispensable component of electronic devices, play an important role in signal and power transmission. The functionality of connectors in the prior art is relatively simple. When used in harsh environments such as high voltage and high interference, connectors are usually required to have stronger shielding performance, circuit fuse protection and other functions. This leads to the existing connectors being prone to insufficient anti-interference performance and poor circuit protection capabilities in actual applications. When applied to connectors, it is necessary to set up corresponding external circuits, which leads to an increase in the overall cost of the equipment.

[0047] However, existing connectors also generally have deficiencies in shielding performance, especially in the poor suppression of external interference such as electromagnetic interference and radio frequency interference. This lack of shielding effect not only affects the integrity of the signal, but may also cause unstable operation of the equipment, thereby causing failures or reducing its working efficiency. In order to ensure a compact structure, the connectors in the prior art usually have a small overall coverage range of the shielding elements and a limited shielding range; or a shielding circuit needs to be set externally, which makes the overall structure of the connector more complicated. At the same time, due to the additional shielding circuit, the reliability of the connector is further reduced, which means that external electromagnetic interference can still affect the connection signal when transmitting the signal. The additional shielding circuit will also increase the manufacturing cost.

[0048] Based on the technical problems existing in the prior art, refer to Figures 1 to 7As shown, an embodiment of the present invention provides a connector device, which includes a socket assembly 100 and a plug assembly 200; the socket assembly 100 includes a socket shell 110, a terminal structure 120 and a full-segment shielding cover, the terminal structure 120 is arranged in the socket shell 110 and is used to connect an external first cable, the full-segment shielding cover is arranged around the terminal structure 120, when the terminal structure 120 is connected to the first cable, at least part of the full-segment shielding cover also surrounds the first cable at the same time; the plug assembly 200 includes a plug housing 210 and a plug terminal 220, the plug terminal 220 is arranged in the plug housing 210 and is used to connect to an external second cable, the plug housing 210 is detachably connected to the socket shell 110; when the plug housing 210 is connected to the socket shell 110, the full-segment shielding cover is at least partially arranged around the plug terminal 220, and the first cable is electrically connected to the second cable; wherein the terminal structure 120 includes a fuse 121 and a shunt terminal 122, and the fuse 121 and the shunt terminal 122 are used to be electrically connected to the plug terminal 220 respectively.

[0049] In the connector device of this embodiment, by setting a separate fuse 121 and a shunt terminal 122 in the socket assembly 100, the fuse 121 and the shunt terminal 122 can be connected to the plug assembly 200 respectively to form at least two parallel circuits in the connector device, thereby realizing the shunt function of the connector device; at the same time, the circuit where the fuse 121 is located can realize self-fusing protection, further improving the protection performance of the connector device. In addition, by setting a full-section shielding cover surrounding the terminal structure 120, the circuit in the connector device can be effectively shielded and protected to improve the signal transmission quality of the connector device.

[0050] In the connector device of the present embodiment, by providing a full-segment shielding cover and the cooperation of the fuse 121 and the shunt terminal 122, not only can the signal shielding protection function of the connector device be realized, but also the integration degree of the connector device can be improved, the overall structure is more compact, and the use effect is good. In addition, in the present embodiment, the fuse 121 and the shunt terminal 122 integrated in the socket assembly 100 can form at least two circuits at one end of the socket assembly 100. When the plug assembly 200 is connected to the socket assembly 100, the two circuits can simultaneously realize the input and output functions of the connector device, or the two circuits are used to transmit different signals respectively, which is not limited here.

[0051] It should be noted that in the present application, the first cable refers to the cable connected to the socket assembly 100, the second cable refers to the cable connected to the plug assembly 200, the second cable is a multi-channel cable and is electrically connected to the fuse 121 and the shunt terminal 122 in the connector device, and the external cables are electrically connected or signal connected to the socket assembly 100 and the plug assembly 200, respectively, and after the socket assembly 100 and the plug assembly 200 are connected, electrical and signal conduction and corresponding transmission functions can be achieved through the connector device. Of course, in some embodiments, the socket assembly 100 can also be directly connected to a conductive element or structure such as a wiring copper column, which is not the only limitation here.

[0052] Since the connector device of this embodiment introduces a shielding cover structure that fully covers the terminal structure 120, the connector device can significantly enhance the protection against external electromagnetic interference and radio frequency interference. This full-segment shielding structure not only improves the integrity of the signal, but also reduces signal loss and distortion caused by interference, which helps to enhance the working stability of the device in harsh environments. In addition, this improvement also improves the performance of the connector device during high-frequency signal transmission, especially in terms of data transmission rate and reliability.

[0053] Specifically, see Figure 2 As shown, the terminal structure 120 also includes a connecting terminal 123, a fuse 121 is arranged in the socket housing 110 and is used to be electrically connected to the first circuit of the plug terminal 220, a shunt terminal 122 is arranged in the socket housing 110 and is used to be electrically connected to the second circuit of the plug terminal 220, and a connecting terminal 123 is arranged in the socket housing 110, and the connecting terminal 123 is connected to the fuse 121 and is used to be connected to an external circuit such as a first first cable.

[0054] In this embodiment, the fuse 121 is provided in the circuit of the socket assembly 100, and the fuse 121 can protect the circuit. When an overload or short circuit occurs in a circuit connected between the plug terminal 220 and the fuse 121, the fuse 121 can quickly cut off the current to prevent the current from damaging the connector device or the connected equipment, thereby improving the safety of the connector device and protecting the equipment from damage in an emergency, thereby improving the safety.

[0055] By setting the shunt terminal 122 and the fuse 121 to be connected to the plug terminal 220 respectively, when the current is conducted through the socket assembly 100, the shunt terminal 122 can aggregate multiple currents into one current, thereby improving the transmission rated load of the socket assembly 100 through the multi-way shunt of the shunt terminal 122, and making the process of supplying power or transmitting signals to the first cable through the connecting terminal 123 more stable and effective. The use of the shunt terminal 122 helps to ensure the load balance of each terminal and reduce the risk of failure caused by overload, thereby further enhancing the reliability of the entire connector device; in addition, when the branch where the fuse 121 is located is disconnected, since the shunt terminal 122 and the fuse 121 are arranged side by side, the circuit where the shunt terminal 122 is located can also transmit normally.

[0056] In one embodiment, the shunt terminal 122 includes a connecting portion 1221 and a plurality of shunt portions 1222 , and the plurality of shunt portions 1222 are respectively connected to the connecting portion 1221 .

[0057] In this embodiment, since the shunt terminal 122 adopts a combined structure of a connecting part 1221 and a plurality of shunt parts 1222, when the input current passes through the connecting part 1221, the current can be distributed to each corresponding shunt part 1222 according to actual needs and current load conditions. Therefore, the current flow direction can be flexibly adjusted according to the application scenario of the connector device to meet the equipment's various needs for power and signal transmission, thereby improving the active adaptability of the connector device.

[0058] In addition, the multi-channel shunt design makes the connector no longer a single-function component, but can be compatible with multiple signal and power transmission requirements. For example, in the field of data communication, different data links can realize their own signal transmission through different shunt parts 1222, thereby realizing multi-channel signal parallel transmission in a physical connector, improving the overall data transmission efficiency. Of course, when the socket assembly 100 is used for multi-channel transmission of different types, corresponding shunt devices need to be set, which will not be repeated here.

[0059] In one embodiment, there are multiple fuses 121 , and the multiple fuses 121 are arranged side by side.

[0060] In this configuration, multiple fuses 121 are respectively connected to multiple branches of the second cable, which not only enables more efficient current protection, but also ensures the normal operation of the equipment with minimal loss when unexpected situations occur in different current paths. Specifically, when the current of a branch of the second cable is overloaded or short-circuited, the corresponding fuse 121 can be blown in time, thereby cutting off the current of the line, while ensuring that the normal operation of other branches of the second cable will not be affected. The scheme of setting the fuses 121 in parallel can provide redundant protection for the connector device, greatly enhancing the safety and stability of the connector device in high-demand applications.

[0061] Specifically, the socket housing 110 includes a socket shell 111 and a socket front cover 112 . The fuse 121 is disposed in the socket shell 111 . The socket front cover 112 is detachably connected to the socket shell 111 and encloses a space for accommodating the fuse 121 .

[0062] Thus, the socket housing 111 has a high strength. As a mounting carrier of the socket assembly 100, the fuse 121 can be effectively protected from damage by the external environment during normal use. In addition, the socket front cover 112 and the socket housing 111 are combined by adopting a detachable connection method. When the fuse 121 is blown due to overload or short circuit, the user only needs to easily remove the front cover 112 to directly replace and maintain the fuse 121 without disassembling the entire socket assembly 100. The structure is simple, which effectively improves the maintenance convenience and use cost of the socket assembly 100. In one embodiment, the socket front cover 112 is snap-fitted with the socket housing 111 so that the socket front cover 112 can be disassembled and assembled. Specifically in this embodiment, a notch for accommodating the socket front cover 112 is provided at the end of the socket front cover 112. During the installation process, the fuse 121 is first inserted into the socket housing 111 from the notch, and then the socket front cover 112 is crimped to the outside of the fuse 121 to complete the assembly.

[0063] Further, the socket housing 111 includes a first connecting portion 1111, a second connecting portion 1112 and a middle portion 1113, the first connecting portion 1111 and the second connecting portion 1112 are respectively connected to the middle portion 1113, and the central axes of the first connecting portion 1111 and the second connecting portion 1112 are arranged in a straight line direction or at an angle; and / or the full-section shielding cover includes a first shielding cover 130 and a second shielding cover 140, the first shielding cover 130 is arranged in the first connecting portion 1111, the second shielding cover 140 is arranged in the second connecting portion 1112, and the first shielding cover 130 is connected to the second shielding cover 140.

[0064] By improving the combined structure of the first connecting part 1111 and the second connecting part 1112, not only can the socket assembly 100 effectively adapt to different types and specifications of plug-in requirements, but it can also be flexibly adjusted and configured according to different specific application scenarios to meet the connection needs of various electrical equipment.

[0065] By setting the first shielding cover 130 and the second shielding cover 140 to correspond to the first cable and the second cable respectively, a shielding function can be provided for the connector device. The first shielding cover 130 and the second shielding cover 140 ensure that a complete shielding space can be formed through an effective connection design, which significantly reduces the negative impact of electromagnetic interference and ensures the normal transmission of current and signals.

[0066] See also Figure 1 and Figure 2 In the illustrated embodiment, the socket housing 110 as a whole extends in a straight direction. At this time, the first shielding cover 130 and the second shielding cover 140 also extend in a straight direction and respectively shield the first cable and the second cable along the cable transmission direction of the connector device. In this embodiment, the first shielding cover 130 and the second shielding cover 140 can be an integral structure.

[0067] See also Figure 6 and Figure 7 As shown, the first connection portion 1111 and the second connection portion 1112 are arranged at 90 degrees. At this time, the first shielding cover 130 and the second shielding cover 140 can be split structures, and the two are connected to form an integral shielding structure when installed in the socket shell 110. For example, the first shielding cover 130 can be connected to the notch of the second shielding cover 140 to form an L-shaped shielding cover structure, and make it able to match the overall shape of the socket shell 110, so that the shielding cover can shield the socket assembly 100 as a whole, and when the socket assembly 100 is connected to the plug assembly 200, the shielding effect of the line can be guaranteed.

[0068] Specifically, the socket housing 110 further includes a socket rear cover 113 , which is connected to the socket shell 111 , and is located at an end away from the socket front cover 112 and is crimped to an end of the connection terminal 123 away from the fuse 121 .

[0069] In this embodiment, the socket back cover 113 is provided to be connected to the socket housing 111. Since the socket back cover 113 is located at an end away from the socket front cover 112, during the assembly process, one end of the connecting terminal 123 is first contacted and connected with the fuse 121, and the other end of the connecting terminal 123 is connected to the first cable. Thereafter, the socket back cover 113 can fix the connecting terminal 123 to ensure the wiring firmness and anti-loosening property of the socket assembly 100, and avoid damage to the connecting terminal 123 caused by mechanical stress that may be generated when plugging and unplugging electrical equipment.

[0070] Specifically, the socket housing 110 further includes a socket bushing 114 , which is embedded in the socket shell 111 .

[0071] In this embodiment, by arranging the socket bushing 114 in the socket housing 111, the socket bushing 114 can provide additional support and protection for the inside of the socket housing 111. The socket bushing 114 can effectively disperse the physical impact of the external fasteners on the socket housing 111, and reduce the impact of vibration on the internal circuit of the socket assembly 100, ensuring the stability and continuity of the electrical connection. In addition, when the connector device is running, the socket bushing 114 can also conduct the heat in the socket housing 111 to assist the heat dissipation of the socket assembly 100, further ensuring the safety and stability of the socket assembly 100, and preventing electrical failures caused by overheating under high-load use.

[0072] In one embodiment, the outer wall of the socket shell 110 is provided with a snap-fitting protrusion 11121; the plug assembly 200 also includes a plug lock 230, which is movably connected to the plug shell 210; when the plug shell 210 is connected to the socket shell 110, the plug lock 230 is snap-fitted with the snap-fitting protrusion 11121.

[0073] Specifically, the matching structure of the snap-fit ​​protrusion 11121 and the plug lock 230 can effectively realize the mechanical locking between the socket assembly 100 and the plug assembly 200, thereby preventing the plug assembly 200 from falling off or loosening due to external force, thereby effectively improving the electrical connection reliability of the connector device, especially in high-load and high-frequency plugging and unplugging environments, such as industrial equipment, commercial appliances, etc., the connection between the socket assembly 100 and the plug assembly 200 is more secure, reducing the power instability or failure problems caused by poor contact during use.

[0074] Furthermore, the socket shell 110 is also provided with a positioning portion 11122, and the snap-fitting protrusion 11121 is arranged on the outer side of the positioning portion 11122; the plug shell 210 is provided with a positioning groove 2111, and the positioning portion 11122 is used to be plugged into and cooperate with the positioning groove 2111, and the plug lock 230 at least partially extends into the positioning groove 2111.

[0075] In this embodiment, by providing the positioning portion 11122 to cooperate with the positioning groove 2111, it is ensured that the plug housing 210 can be accurately aligned in the horizontal and vertical directions when inserted into the socket housing 110. This precise alignment can not only avoid the degradation of electrical performance due to poor contact between the socket assembly 100 and the plug assembly 200, but also reduce the wear and loose contact caused by the relative displacement between the socket assembly 100 and the plug assembly 200, thereby effectively extending the service life of the device.

[0076] During the connection between the socket assembly 100 and the plug assembly 200, the positioning portion 11122 is first inserted into the positioning groove 2111 and slides along the positioning groove 2111 to bring the socket assembly 100 close to the plug assembly 200. When the plug lock 230 is engaged with the snap-in protrusion 11121, the socket assembly 100 and the plug assembly 200 can be fixed; when it is necessary to release the lock of the plug lock 230, it is only necessary to press the plug lock 230 to separate it from the snap-in protrusion 11121.

[0077] When the plug lock 230 is engaged with the snap-in protrusion 11121, a double locking structure can be formed. First, the insertion of the socket assembly 100 and the plug assembly 200 can achieve single locking, and the connection between the plug lock 230 and the snap-in protrusion 11121 can achieve double locking, thereby enabling the connector device to effectively resist external pulling force and applied force, avoiding power interruption or equipment failure caused by accidental removal of the plug assembly 200, so that the connector device can be used in high vibration environments (such as industrial occasions), and the risk of electrical connection failure is significantly reduced through enhanced locking efficiency.

[0078] In one embodiment, the plug housing 210 includes a plug shell 211, a plug tail cover 212 and a fixing member 213. The plug tail cover 212 is detachably connected to the plug shell 211 and encloses a space for accommodating the fixing member 213. The fixing member 213 is used to connect a second cable. The plug assembly 200 also includes a plug shielding cover 240, which is at least partially arranged around the fixing member 213.

[0079] First, the detachable connection design of the plug tail cover 212 allows the user to easily remove and replace the fixing member 213 when necessary, making the plug assembly 200 more convenient to maintain and upgrade. For example, when the second cable is damaged or needs to be replaced, the user only needs to remove the plug tail cover 212 without replacing the entire plug assembly 200, thereby effectively reducing maintenance costs and extending the service life of the product.

[0080] Secondly, by arranging a fixing 213 inside the plug housing 211, the fixing 213 can safely and effectively connect the second cable, ensuring the stability and reliability of the electrical connection, and can ensure that the electrical performance is not affected under high load or high frequency plugging and unplugging conditions, thereby reducing the probability of signal loss and failure due to poor contact.

[0081] By arranging the plug shielding cover 240 on the fixing member 213, the plug shielding cover 240 can effectively block the interference of external electromagnetic waves and protect the internal circuit from interference, thereby ensuring the stability and reliability of signal transmission. In addition, the plug shielding cover 240 can also reduce the interference between cables and improve the anti-interference ability of the entire system, especially in a complex environment where multiple signals coexist, significantly improving the performance of the device.

[0082] Furthermore, the plug assembly 200 further includes a fixing shell 280 , and the fixing member 213 is at least partially inserted into the plug shielding cover 240 . The fixing shell 280 is snap-fitted with the plug shielding cover 240 and is crimped onto the fixing member 213 .

[0083] In this embodiment, the fixing member 213 is fixed by providing a fixing shell 280, and the fixing shell 280 can provide additional support and protection for the fixing member 213, thereby enhancing the durability of the entire plug assembly 200 during the plugging and unplugging process. When the plug assembly 200 is inserted into or unplugged from the socket assembly 100, the physical impact and pulling force are mainly borne by the fixing shell 280, which can effectively reduce the pressure directly acting on the fixing member 213 and the plug shielding cover 240, thereby reducing the potential risk of damage.

[0084] Secondly, the snap-fit ​​design between the fixed shell 280 and the plug shield 240 can ensure a stable and reliable contact surface between the two, thereby improving the firmness of the electrical connection. This structure can effectively prevent the plug from loosening or poor contact during use, and help maintain electrical safety under higher loads.

[0085] In one embodiment, a spring sheet is disposed inside the plug shielding cover 240, and the fixing member 213 is inserted into the plug shielding cover 240 and engaged with the spring sheet. At this time, the spring sheet is concavely disposed on the outer wall of the plug shielding cover 240. By connecting the fixing shell 280 to the plug shielding cover 240, the fixing shell 280, the plug shielding cover 240 and the fixing member 213 can be combined to further improve the overall strength of the plug assembly 200.

[0086] Furthermore, the plug assembly 200 further includes a plug shielding ring 250 , which is sleeved and connected to the plug housing 210 , and the second cable is inserted into the plug shielding ring 250 .

[0087] By arranging the plug shielding ring 250 on the outside of the second cable, an effective shielding area can be formed on the outside of the second cable, which can block the interference of external electromagnetic waves and ensure the pure transmission of signals. In addition, the plug shielding ring 250 can also be connected to the ground to enhance the anti-interference ability of the entire system, and ensure the stability of the signal through electromagnetic shielding, especially in the process of high-frequency signal transmission, significantly reducing the signal loss caused by interference.

[0088] Secondly, the design of the plug shielding ring 250 also helps to improve the mechanical stability of the structure. Through the firm connection on the plug housing 210, the plug shielding ring 250 provides additional support for the fixing member 213 and the second cable, so that the entire assembly can withstand greater tension and pressure, and can reduce the looseness or poor contact of the plug assembly 200 caused by physical pressure, thereby improving the reliability and durability of the device.

[0089] Specifically, the plug shielding ring 250 includes a first shielding ring 251 and a second shielding ring 252 . The first shielding ring 251 is sleeved on the outside of the second shielding ring 252 , and the second cable is inserted into the second shielding ring 252 .

[0090] In this embodiment, the combination of the first shielding ring 251 and the second shielding ring 252 forms a multi-layer shielding structure, and this design significantly improves the anti-interference ability. The outer shielding formed by the first shielding ring can effectively resist electromagnetic interference in the external environment and avoid the invasion of electromagnetic waves, thereby protecting the signal quality of the second cable transmission. The second shielding ring 252 serves as an inner shielding to further prevent the mixing of internal and external signals and ensure the stability and security of the signal during transmission. This two-layer shielding structure complements each other and creates an extremely good environment for high-frequency signal transmission. It is particularly suitable for sensitive equipment that resists various electromagnetic interferences, such as audio equipment, data transmission equipment and other high-frequency communication systems.

[0091] Secondly, the design of the plug shielding ring 250 effectively reduces the impact of cable vibration or tension on signal transmission. The outer first shielding ring 251 enhances the stability of the overall structure by closely matching the plug housing 210, preventing poor connection caused by improper operation. At the same time, the additional protection provided by the first shielding ring 251 enables the plug assembly to maintain the integrity of its internal structure when subjected to external impact or pressure, thereby improving the durability and fatigue resistance of the plug.

[0092] Furthermore, the plug assembly 200 further includes a cable sealing ring 260, which is disposed in the plug housing 210, and the second cable is passed through the cable sealing ring 260;

[0093] In this embodiment, by disposing a cable sealing ring 260 in the plug housing 210 , the cable sealing ring 260 can prevent external liquid, dust and other environmental pollutants from invading the plug assembly 200 , thereby protecting the normal operation of internal electronic components.

[0094] In one embodiment, the plug assembly 200 further includes a plug sealing ring 270 . The plug sealing ring 270 is connected to the plug housing 210 . The plug sealing ring 270 is used to seal between the plug housing 210 and the socket housing 110 .

[0095] In this embodiment, a plug seal ring 270 is provided between the socket assembly 100 and the plug assembly 200, and the plug seal ring 270 can seal the gap between the plug housing 210 and the socket housing 110, forming an effective sealing protection. The use of the plug seal ring 270 can effectively reduce the corrosion, short circuit and signal interference caused by environmental factors, and provide strong protection for the plug connection, especially in outdoor use or harsh environment, to ensure the reliability and safety of the device.

[0096] In one embodiment, the socket assembly 100 further includes a socket sealing ring 150 , which is connected to the socket housing 110 and is located on a side of the socket housing 110 away from the plug housing 210 . The socket sealing ring 150 is used to seal between the socket housing 110 and external components.

[0097] The socket seal ring 150 can reduce the intrusion of moisture and pollutants into the gap between the socket housing 110 and the external components, and prevent the external environment from damaging the internal circuit of the socket. At the same time, the good sealing performance of the socket seal ring 150 also helps to prevent the poor contact caused by the accumulation of water vapor and dust during the use of the socket, and significantly improves the smoothness of plug insertion and removal. Specifically, the cable seal ring 260, the plug seal ring 270 and the socket seal ring 150 can be silicone seal rings or rubber seal rings. This is not the only limitation.
