[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0045] Under the background of rapid development of information technology, connectors, as an indispensable part of electronic devices, play an important role in signal and power transmission. The connectors in the prior art have relatively single functionality. When applied to harsh use environments such as high voltage and high interference, the connectors usually need to have stronger shielding performance, circuit fuse protection, and other functions, which leads to the problems of insufficient anti-interference performance and poor circuit protection capability of the existing connectors in actual application. When applied to connectors, corresponding external circuits need to be additionally set, thereby leading to an increase in the overall cost of the device.

[0046] However, the existing connectors also generally have deficiencies in shielding performance, especially in the suppression effect of external interference such as electromagnetic interference and radio frequency interference. The lack of such shielding effect not only affects the integrity of the signal, but also can cause the device to operate unstably, thereby causing failure or reducing its working efficiency. In order to ensure compact structure, the shielding elements of the connectors in the prior art usually have a small overall coverage range, and the shielding range is limited; or a shielding circuit needs to be externally set, which leads to a more complex overall structure of the connector, and additionally reduces the reliability of the connector due to the additional shielding circuit, which leads to the influence of external electromagnetic interference on the connection signal when transmitting the signal, and the additional shielding circuit also leads to an increase in manufacturing cost.

[0047] Based on the technical problems in the prior art, reference is made to Figures 1 to 7As shown, the utility model embodiment provides a kind of connector device, it includes socket assembly 100 and plug assembly 200;Socket assembly 100 includes socket shell 110, terminal structure 120 and full segment shield cover, terminal structure 120 is located in socket shell 110 and is used to connect the first cable outside, full segment shield cover is arranged around terminal structure 120, when terminal structure 120 is connected with the first cable, full segment shield cover at least part structure also simultaneously surrounds the first cable;Plug assembly 200 includes plug shell 210 and plug terminal 220, plug terminal 220 is located in plug shell 210 and is used to connect the second cable outside, plug shell 210 can be detachably connected to socket shell 110;When plug shell 210 is connected with socket shell 110, full segment shield cover at least part surrounds plug terminal 220 setting, and the first cable is electrically connected with the second cable;Wherein, terminal structure 120 includes fuse 121 and shunt terminal 122, and fuse 121 and shunt terminal 122 are used to be electrically connected in plug terminal 220 respectively.

[0048] In the connector device of the embodiment, by setting the split fuse 121 and shunt terminal 122 in the socket assembly 100, the fuse 121 and shunt terminal 122 can be connected with 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 the full segment shield cover around the terminal structure 120, the lines in the connector device can be effectively shielded and protected, to improve the signal transmission quality of the connector device.

[0049] In the connector device of the embodiment, by setting the full segment shield cover and the fuse 121 and shunt terminal 122 cooperate, not only the signal shielding protection function of the connector device can 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 embodiment, the fuse 121 and 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 with 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 for transmitting different signals respectively, which is not limited.

[0050] It should be noted that in this application, the first cable refers to the cable connected with the socket assembly 100, the second cable refers to the cable connected with the plug assembly 200, the second cable is a multi-cable and is respectively electrically connected with the fuse 121 and the shunt terminal 122 in the connector device, the external cable is respectively electrically connected or signal connected with the socket assembly 100 and the plug assembly 200, and after the socket assembly 100 and the plug assembly 200 are connected, the electrical connection, signal conduction and corresponding transmission function can be realized through the connector device. Of course, in some embodiments, the socket assembly 100 can also be directly connected with a conductive element or structure such as a wiring copper column, which is not limited here.

[0051] Due to the introduction of the shielding cover structure of the full-segment covering terminal structure 120 in the connector device of the embodiment, the connector device can significantly enhance the protection ability against external electromagnetic interference and radio frequency interference. This full-segment shielding structure not only improves the signal integrity, but also reduces the signal loss and distortion caused by interference, which helps to enhance the working stability of the equipment in harsh environments. In addition, this improvement also enables the connector device to perform better in high-frequency signal transmission, especially in terms of data transmission rate and reliability.

[0052] Specifically, referring to Figure 2 As shown, the terminal structure 120 further includes a connecting terminal 123, the fuse 121 is arranged in the socket housing 110 and is used to be electrically connected with the first loop of the plug terminal 220, the shunt terminal 122 is arranged in the socket housing 110 and is used to be electrically connected with the second loop of the plug terminal 220, the connecting terminal 123 is arranged in the socket housing 110, and the connecting terminal 123 is connected with the fuse 121 and is used to be connected with an external circuit such as the first cable.

[0053] In the embodiment, by arranging the fuse 121 in the circuit of the socket assembly 100, the fuse 121 can protect the circuit. When the circuit connected with the fuse 121 of the plug terminal 220 is overloaded or short-circuited, the fuse 121 can quickly cut off the current to prevent damage to the connector device or connected equipment, thereby improving the safety of the connector device and protecting the equipment from damage in emergency situations, and the safety is also improved.

[0054] When the current is conducted through the socket assembly 100, the shunt terminal 122 can aggregate multiple currents into one by connecting the shunt terminal 122 and the fuse 121 with the plug terminal 220 respectively, thereby improving the transmission rated load of the socket assembly 100 through the multi-path 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 balancing of each terminal, reduces the risk of failure caused by overload, and further enhances the reliability of the entire connector device; in addition, when the branch where the fuse 121 is located is disconnected, the circuit where the shunt terminal 122 is located can also normally transmit due to the side-by-side arrangement of the shunt terminal 122 and the fuse 121.

[0055] In an 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 connected to the connecting portion 1221 respectively.

[0056] In this embodiment, since the shunt terminal 122 adopts the combined structure of the connecting portion 1221 and the plurality of shunt portions 1222, when the input current passes through the connecting portion 1221, the current can be distributed to each corresponding shunt portion 1222 according to actual needs and current load conditions, thereby the current flow can be flexibly adjusted according to the application scenario of the connector device to meet the various needs of equipment for power and signal transmission, thereby improving the active adaptive ability of the connector device.

[0057] In addition, the multi-path shunt design makes the connector no longer a single-function component, but can meet the needs of multiple signal and power transmission. For example, in the field of data communication, different data links can realize their own signal transmission through different shunt portions 1222, thereby realizing multi-path parallel signal transmission in one physical connector, improving the overall data transmission efficiency. Of course, when the socket assembly 100 is applied to multi-path different types of transmission, corresponding shunt devices need to be set, which will not be described here.

[0058] In an embodiment, the number of fuses 121 is multiple, and the plurality of fuses 121 are arranged side by side.

[0059] With the above arrangement, the plurality of fuses 121 are respectively connected with the plurality of branches of the second cable, so that not only the current protection can be more efficient, but also the normal operation of the equipment can be ensured with minimal loss in the event of an accident 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 fused in time to cut off the current of the line, while ensuring that the normal work of other branches of the second cable will not be affected. The scheme of using parallel fuses 121 can provide redundant protection for the connector device, greatly enhancing the safety and stability of the connector device in high-demand applications.

[0060] Specifically, the socket housing 110 includes a socket shell 111 and a socket front cover 112, the fuses 121 are arranged in the socket shell 111, and the socket front cover 112 is detachably connected to the socket shell 111 and encloses a space for accommodating the fuses 121.

[0061] With the above arrangement, the socket shell 111 has high strength and can effectively protect the fuses 121 from damage by the external environment during normal use as a mounting carrier of the socket assembly 100. In addition, the socket front cover 112 and the socket shell 111 are combined by using a detachable connection method, so that when the fuses 121 are fused due to overload or short circuit, the user only needs to easily detach the socket front cover 112 to directly replace and maintain the fuses 121 without the need to disassemble the entire socket assembly 100, which is simple in structure and effectively improves the maintenance convenience and use cost of the socket assembly 100. In an embodiment, the socket front cover 112 is snap-fitted with the socket shell 111 to facilitate the disassembly and assembly of the socket front cover 112. Specifically, in this embodiment, the end of the socket front cover 112 is provided with a slot for accommodating the socket front cover 112, and during installation, the fuses 121 are first inserted into the socket shell 111 from the slot, and then the socket front cover 112 is crimped on the outside of the fuses 121 to complete the assembly.

[0062] Further, the socket shell 111 includes a first connecting portion 1111, a second connecting portion 1112, and an intermediate portion 1113, the first connecting portion 1111 and the second connecting portion 1112 are respectively connected to the intermediate portion 1113, and the central axes of the first connecting portion 1111 and the second connecting portion 1112 are arranged in a straight line or at an angle; and / or the full-section shield cover includes a first shield cover 130 and a second shield cover 140, the first shield cover 130 is arranged in the first connecting portion 1111, the second shield cover 140 is arranged in the second connecting portion 1112, and the first shield cover 130 is connected to the second shield cover 140.

[0063] Through the improvement of the combined structure of the first connecting part 1111 and the second connecting part 1112, the socket assembly 100 can not only effectively adapt to the plug-in requirements of different types and different specifications, but also can be flexibly adjusted and configured according to different specific application scenarios to meet the connection needs of various electrical equipment.

[0064] By setting the first shielding cover 130 and the second shielding cover 140 corresponding to the first cable and the second cable respectively, the shielding function can be provided for the connector device, and the first shielding cover 130 and the second shielding cover 140 can ensure that a complete shielding space is formed through effective connection design, thereby significantly reducing the negative effects of electromagnetic interference and protecting the normal transmission of current and signals.

[0065] Referring to the embodiments shown in Figure 1 and Figure 2 , the socket housing 110 extends in a straight line direction, and at this time, the first shielding cover 130 and the second shielding cover 140 also extend in a straight line direction and shield and protect 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.

[0066] Referring to Figure 6 and Figure 7 , the first connecting part 1111 and the second connecting part 1112 are arranged at 90°, and at this time, the first shielding cover 130 and the second shielding cover 140 can be a split structure and connected to form an overall shielding structure when installed in the socket housing 110. For example, the first shielding cover 130 can be connected with the notch of the second shielding cover 140 to form an L-shaped shielding cover structure, and the shielding cover can be matched with the overall shape of the socket housing 110, so that the shielding cover can shield the entire socket assembly 100, and when the socket assembly 100 is connected with the plug assembly 200, the shielding effect of the line can be ensured.

[0067] Specifically, the socket housing 110 further comprises a socket rear cover 113, the socket rear cover 113 is connected to the socket shell 111, and the socket rear cover 113 is located at one end away from the socket front cover 112 and is crimped to one end of the connecting terminal 123 away from the fuse 121.

[0068] In this embodiment, the socket rear cover 113 is connected to the socket shell 111, and since the socket rear cover 113 is located at one end away from the socket front cover 112, during assembly, one end of the connecting terminal 123 is first connected in contact with the fuse 121, and the other end of the connecting terminal 123 is connected with the first cable. Then, the socket rear cover 113 can fix the connecting terminal 123, so as to ensure the firmness and anti-looseness of the connection of the socket assembly 100, and avoid damage to the connecting terminal 123 caused by mechanical stress when the electrical equipment is plugged in or out.

[0069] Specifically, the socket shell 110 further comprises a socket bushing 114 embedded in the socket housing 111.

[0070] In this embodiment, by providing the socket bushing 114 in the socket housing 111, the socket bushing 114 can provide additional support and protection for the interior of the socket housing 111, effectively dispersing the physical impact of external fasteners on the socket housing 111 and reducing the impact of vibration on the internal circuit of the socket assembly 100, ensuring the stability and continuity of electrical connection. In addition, the socket bushing 114 can also conduct heat in the socket housing 111 to assist in heat dissipation of the socket assembly 100 when the connector device is in operation, further ensuring the safety and stability of the socket assembly 100 and preventing electrical failure caused by overheating in high-load use cases.

[0071] In an embodiment, the outer wall of the socket shell 110 is provided with a clamping protrusion 11121; the plug assembly 200 further comprises a plug lock 230 movably connected to the plug housing 210; when the plug housing 210 is connected to the socket shell 110, the plug lock 230 is clamped and matched with the clamping protrusion 11121.

[0072] Specifically, the clamping protrusion 11121 and the plug lock 230 can effectively realize 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, high-frequency plugging 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 problem of unstable power supply or failure caused by poor contact during use.

[0073] Further, the socket shell 110 is further provided with a positioning portion 11122, and the clamping protrusion 11121 is arranged outside the positioning portion 11122; the plug housing 210 is provided with a positioning groove 2111, and the positioning portion 11122 is used for plug-in matching with the positioning groove 2111, and the plug lock 230 at least partially extends into the positioning groove 2111.

[0074] In this embodiment, by setting the positioning portion 11122 and the positioning groove 2111 to cooperate, it is ensured that the plug housing 210 can be accurately aligned in horizontal and vertical directions when inserted into the socket shell 110. This precise alignment not only avoids the decline in electrical performance caused by poor contact between the socket assembly 100 and the plug assembly 200, but also reduces wear and loose contact caused by relative displacement between the socket assembly 100 and the plug assembly 200, thereby effectively prolonging the service life of the equipment.

[0075] During the connection of 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 make the socket assembly 100 close to the plug assembly 200, and then the plug lock buckle 230 can be fixed with the socket assembly 100 and the plug assembly 200 after being clamped with the clamping convex portion 11121; when the locking of the plug lock buckle 230 needs to be released, the plug lock buckle 230 only needs to be pressed to be separated from the clamping convex portion 11121.

[0076] When the plug lock buckle 230 is clamped with the clamping convex portion 11121, a double locking structure is formed, the first one is the plug connection of the socket assembly 100 and the plug assembly 200, and the second one is the connection of the plug lock buckle 230 and the clamping convex portion 11121, thereby making the connector device effectively resist external pulling force and applied force, avoiding power interruption or equipment failure caused by accidental pulling out of the plug assembly 200, so that the connector device can be applied to high-vibration environments (such as industrial environments), and the risk of electrical connection failure is significantly reduced by the enhanced locking performance.

[0077] In an 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, and the fixing member 213 is used for connecting a second cable; the plug assembly 200 further includes a plug shielding cover 240, and the plug shielding cover 240 is at least partially arranged around the fixing member 213.

[0078] Firstly, the detachable connection design of the plug tail cover 212 allows users to easily remove and replace the fixing member 213 when needed, so that the plug assembly 200 has higher maintenance and upgrade convenience. For example, when the second cable is damaged or needs to be replaced, the user only needs to disassemble the plug tail cover 212, without the need to replace the entire plug assembly 200, thereby effectively reducing the maintenance cost and prolonging the service life of the product.

[0079] Secondly, by arranging the fixing member 213 inside the plug shell 211, the fixing member 213 can safely and effectively connect the second cable, ensuring the stability and reliability of the electrical connection, and can ensure the electrical performance not to be affected under high load or high frequency plugging and unplugging conditions, thereby reducing the probability of signal loss and failure caused by poor contact.

[0080] By setting the plug shielding cover 240 on the fixing part 213, the plug shielding cover 240 can effectively block the interference of external electromagnetic waves, protect the internal circuit from interference, and ensure 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 with multiple signals coexisting, significantly improving the performance of the device.

[0081] Further, the plug assembly 200 further comprises a fixed shell 280, the fixing part 213 is at least partially inserted into the plug shielding cover 240, and the fixed shell 280 is in clamping cooperation with the plug shielding cover 240 and is crimped on the fixing part 213.

[0082] In this embodiment, the fixing part 213 is fixed by setting the fixed shell 280, which can provide additional support and protection for the fixing part 213, enhancing the durability of the entire plug assembly 200 during plugging. When the plug assembly 200 is inserted or pulled out of the socket assembly 100, the physical impact and pulling force are mainly borne by the fixed shell 280, which can effectively reduce the pressure acting directly on the fixing part 213 and the plug shielding cover 240, and reduce the risk of potential damage.

[0083] Secondly, the clamping cooperation design between the fixed shell 280 and the plug shielding cover 240 can ensure the stability and reliability of the contact surface between them, thereby improving the firmness of electrical connection. This structure can effectively prevent the plug from loosening or poor contact during use, and also helps to maintain electrical safety under higher load.

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 transmitted by the second cable. The second shielding ring 252 serves as an inner shielding layer to further prevent internal and external signal mixing and ensure the stability and security of the signal during transmission. This two-layer shielding structure complements each other to create an excellent environment for high-frequency signal transmission, especially for sensitive devices such as audio equipment, data transmission equipment, and other high-frequency communication systems.

[0090] Secondly, this 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 through close cooperation with the plug shell 210, preventing poor connection caused by improper operation. At the same time, the additional protection provided by the first shielding ring 251 allows the plug assembly to maintain its internal structural integrity when subjected to external impact or pressure, improving the durability and fatigue resistance of the plug.

[0091] Further, the plug assembly 200 also includes a cable sealing ring 260, which is arranged in the plug shell 210 and the second cable is arranged in the cable sealing ring 260.

[0093] In an embodiment, the plug assembly 200 also includes a plug sealing ring 270 connected to the plug shell 210, and the plug sealing ring 270 is used to seal between the plug shell 210 and the socket shell 110.

[0094] In the embodiment, by arranging the plug sealing ring 270 between the socket assembly 100 and the plug assembly 200, the plug sealing ring 270 can seal the gap between the plug housing 210 and the socket shell 110, forming an effective sealing protection. The use of the plug sealing ring 270 can effectively reduce the problems of corrosion, short circuit and signal interference caused by environmental factors, especially in outdoor use or harsh environment, providing strong protection for plug connection, ensuring the reliability and safety of the equipment.

[0095] In an embodiment, the socket assembly 100 further comprises a socket sealing ring 150, the socket sealing ring 150 is connected to the socket shell 110, and the socket sealing ring 150 is located on the side of the socket shell 110 away from the plug housing 210, and the socket sealing ring 150 is used to seal the gap between the socket shell 110 and the external components.

[0096] The socket sealing ring 150 can reduce the gap between the socket shell 110 and the external components, prevent the invasion of moisture and pollutants, and prevent the damage of the external environment to the internal circuit of the socket. At the same time, the good sealing performance of the socket sealing ring 150 also helps to prevent the contact failure caused by the accumulation of water vapor and dust during use, significantly improving the smoothness of plug insertion and extraction. Specifically, the cable sealing ring 260, the plug sealing ring 270 and the socket sealing ring 150 can be a silica gel sealing ring, a rubber sealing ring. Here is not limited.
