Description

Technical Field

[0001] This application relates to the field of electrical connector technology, and in particular to a connector socket and a connecting device. Background Technology

[0002] A connector is an electrical component used to connect two active devices, primarily functioning to transmit current or signals. It consists of a plug and a socket; when plug and socket are inserted, current or signals are transmitted, enabling connection and communication between electrical devices. In the field of high-voltage sockets, the RAST (Rapid Action Self-locking Terminal) structure is a common quick-connect and locking technology. Currently used RAST sockets lock the plug to the housing, requiring high-precision molds and processing techniques to achieve this locking function, resulting in high costs. Furthermore, the housing material is susceptible to aging and deformation due to long-term use caused by temperature, humidity, and mechanical stress, thus reducing the locking effect and increasing the risk of loosening. Utility Model Content

[0003] This application provides a connector socket and a connecting device, which not only improves the connection stability between the connector socket and the connector plug, but also effectively prevents the connector plug from being inserted in reverse, thereby enhancing the user experience.

[0004] In a first aspect, embodiments of this application provide a connector socket, fixedly mounted on a circuit board and used to mate with a connector plug to achieve electrical connection. The connector socket includes a socket body and socket prongs, wherein:

[0005] The socket body includes a base and a foolproof protrusion disposed on the top surface of the base, the foolproof protrusion being used to prevent mis-connection of the connector plug;

[0006] The socket prongs pass through the base, and a first prong connecting portion extends from the top surface of the base and a second prong connecting portion extends from the bottom surface of the base. The second prong connecting portion is used to insert into the circuit board and realize electrical connection with the circuit board. The first prong connecting portion has a locking hole for cooperating with the connector plug to realize a locking connection.

[0007] The connector socket according to the first aspect of this application has at least the following advantages: when the connector plug is inserted into the connector socket, the connection is achieved through direct locking via the engagement of the socket prongs and the terminals of the connector plug, thus improving the connection stability between the connector socket and the connector plug. Simultaneously, the socket body is provided with anti-foolproof protrusions, which effectively prevent the connector plug from being inserted backwards, avoiding electrical short circuits and equipment damage caused by misoperation, providing strong compatibility, and enhancing the user experience.

[0008] According to some embodiments of the present invention, a connector socket is provided inside the socket body with a plurality of mounting portions arranged side by side for the socket prongs to pass through, wherein the spacing between each mounting portion is consistent. The even distribution of the socket prongs within the socket body not only improves the structural stability of the connector socket but also makes the insertion of the connector plug smoother.

[0009] According to some embodiments of the present invention, the connector socket includes a first anti-foolproof bump and a second anti-foolproof bump. The first anti-foolproof bump and the second anti-foolproof bump are arranged side by side between two different mounting portions. The first anti-foolproof bump is located in the middle of the base, and the second anti-foolproof bump is located at one end of the base. The side-by-side arrangement of the first and second anti-foolproof bumps forms a dual anti-foolproof mechanism, which not only effectively prevents the plug from being inserted backwards or incorrectly, making the connector plug insertion process more intuitive and simple, but also eliminates the need for users to worry about incorrect insertion direction or position, avoiding the possibility of electrical short circuits or equipment damage caused by misoperation. This improves the safety and reliability of the connector socket and enhances the user experience.

[0010] According to some embodiments of the present invention, the first anti-fooling bump and the second anti-fooling bump have different shapes, and the width of the first anti-fooling bump is greater than the width of the second anti-fooling bump. Because the first and second anti-fooling bumps have different shapes and widths, the connector plug must match both anti-fooling bumps simultaneously to be correctly inserted. This achieves a dual anti-fooling mechanism, improving the anti-fooling effect of the connector socket, effectively preventing the connector plug from being inserted backwards or incorrectly, and enhancing the safety and reliability of the connector socket.

[0011] According to some embodiments of the present invention, the connector socket has mounting holes in the mounting portion. The second insert connecting portion is inserted into the mounting holes and mounted on the mounting portion, such that the height of the socket insert is greater than the height of the first anti-fooling bump and the second anti-fooling bump. The second insert connecting portion of the socket insert is installed in these mounting holes by insertion, thereby fixing it to the mounting portion. Furthermore, after installation, the socket insert protrudes from the surface of the anti-fooling bump, so that when the connector plug is inserted, the insert can first contact the connector plug, ensuring the stability and reliability of the electrical connection. The height of the anti-fooling bump is lower than that of the socket insert, allowing the connector plug to more accurately engage with the anti-fooling bump during insertion, further enhancing the reliability of the anti-fooling function.

[0012] According to some embodiments of the present invention, the connector socket body further includes a first positioning groove disposed in the middle of the base and a second positioning groove disposed at one end of the base and located on one side of the second anti-fooling protrusion. The first positioning groove and the second positioning groove are used for guiding and positioning when the connector socket is mated with the connector plug. The first positioning groove and the second positioning groove provide a clear guiding path for the insertion of the connector plug. During the insertion process, the positioning groove cooperates with the corresponding protrusion or corresponding structure on the connector plug, reducing the shaking and offset of the connector plug during insertion, allowing the connector plug to be inserted into the connector socket more smoothly, guiding the connector plug to be correctly inserted into the connector socket, and ensuring the precise mating of the connector plug and the connector socket, thereby improving the user experience.

[0013] According to some embodiments of the present invention, the connector socket body further includes a plurality of reinforcing ribs disposed on the bottom surface of the base, the plurality of reinforcing ribs being arranged side-by-side and spaced apart between each of the second insert connecting portions. By providing reinforcing ribs, the bending and torsional resistance of the base can be improved, especially when the connector socket is frequently plugged in and unplugged or subjected to external impact, effectively preventing deformation or damage to the base and improving the durability of the connector socket. Furthermore, the side-by-side and spaced arrangement of the reinforcing ribs between the second insert connecting portions fully utilizes the space on the bottom surface of the base, enhancing structural strength while avoiding interference with the installation and function of the inserts.

[0014] According to some embodiments of the present invention, the connector socket body further includes a positioning post disposed on the bottom surface of the base, wherein the positioning post is connected to at least one reinforcing rib. By providing a positioning post on the bottom surface of the base, a precise reference point can be provided for the assembly of the connector socket. The positioning post ensures that the connector socket is accurately aligned and fixed in the designated position, reducing errors during assembly. Simultaneously, the positioning post and the reinforcing rib form an integral structure, improving the mechanical strength and stability of the base, effectively preventing deformation or damage to the base during use, and extending the service life of the connector socket.

[0015] According to some embodiments of the present invention, the connector socket body further includes a plurality of heat dissipation holes disposed on the bottom surface of the base, the heat dissipation holes extending toward the top surface of the base. The heat dissipation holes disposed on the bottom surface of the base form a good air circulation channel, which can improve the heat dissipation efficiency of the connector socket, reduce the temperature of the connector socket during use, and thus extend the service life of the connector socket.

[0016] Secondly, embodiments of this application also provide a connection device, including: a connector plug and a connector socket according to any one of the embodiments of the first aspect.

[0017] The connection device according to the second aspect of this application has at least the following advantages: when the connector plug is inserted into the connector socket, the connection is achieved through direct locking via the engagement of the socket prongs and the terminals of the connector plug, thus improving the connection stability of the connection device. Simultaneously, the socket body of the connector socket is provided with anti-foolproof protrusions, which effectively prevent the connector plug from being inserted backwards. This not only avoids electrical short circuits and equipment damage caused by misoperation, but also provides strong compatibility and enhances the user experience.

[0036] The embodiments of this application will be further described below with reference to the accompanying drawings.

[0037] Firstly, such as Figures 1 to 4 As shown, this application embodiment provides a connector socket 100, which is fixedly installed on a circuit board and used to mate with a connector plug to achieve electrical connection. The connector socket 100 includes: a socket body 110 and a socket insert 120, wherein: the socket body 110 includes a base 111 and a foolproof protrusion 112 disposed on the top surface of the base 111, the foolproof protrusion 112 is used to prevent mis-interlocking of the connector plug; the socket insert 120 passes through the base 111 and extends a first insert connecting portion 121 from the top surface of the base 111 and a second insert connecting portion 122 from the bottom surface of the base 111, the second insert connecting portion 122 is used to insert into the circuit board and achieve electrical connection with the circuit board, and the first insert connecting portion 121 has a locking hole 1211 for cooperating with the connector plug to achieve locking connection.

[0038] It should be noted that a foolproof protrusion 112 is provided on the top surface of the base 111 to prevent incorrect mating of the connector plug, ensuring that the plug can only be inserted in the correct manner. Further, as... Figure 4 As shown, the socket insert 120 of the connector socket 100 passes through the base 111 during assembly. The first insert connecting part 121 extends from the top surface of the base 111, and the second insert connecting part 122 extends from the bottom surface of the base 111. The second insert connecting part 122 is used to insert into the circuit board and realize electrical connection. The first insert connecting part 121 is provided with a locking hole 1211.

[0039] Understandably, when the connector plug is inserted into the connector socket 100, the socket prongs 120 engage with the terminals of the connector plug to directly lock the connection, achieving an efficient and stable connection and improving the connection stability between the connector socket 100 and the connector plug. Simultaneously, the socket body 110 is equipped with a foolproof protrusion 112, which effectively prevents the connector plug from being inserted backwards. This not only avoids electrical short circuits and equipment damage caused by misoperation but also provides strong compatibility and enhances the user experience.

[0040] In some embodiments, such as Figure 2 As shown, the socket body 110 has multiple mounting portions 113 arranged side-by-side inside, through which socket prongs 120 pass. The spacing between each mounting portion 113 is uniform. It is understood that each socket prong 120 passes through and is mounted on a mounting portion 113, ensuring stable installation and correct positioning of the socket prong 120. In one embodiment, the socket body 110 has four mounting portions 113, with equal spacing between each portion (e.g., 3 mm, 5 mm). Correspondingly, four socket prongs 120 are also provided, which can be fixed to the mounting portions 113 by snap-fit ​​or welding. Furthermore, the uniform distribution of the socket prongs 120 within the socket body 110 ensures the stability of current or signal transmission, avoiding poor contact or signal attenuation due to inconsistent prong positions. Additionally, when the connector plug is inserted, the uniform distribution of the socket prongs 120 allows for smoother insertion, reducing resistance and sticking during insertion and removal, thus improving the user experience.

[0041] In some embodiments, the second insert connector 122 is provided with two pins (not shown) for connection and installation with a circuit board. It is understood that the pins are protruding portions of the second insert connector 122 used for connection with the circuit board, and are typically made of metal with good conductivity and mechanical strength. During actual installation, the pins can be fixed to the pads on the circuit board by soldering, or inserted into the sockets on the circuit board by plugging, thereby achieving an electrical connection between the connector socket 100 and the circuit board.

[0042] In some embodiments, such as Figures 1 to 3 As shown, the anti-misoperation bump 112 includes a first anti-misoperation bump 1121 and a second anti-misoperation bump 1122. The first anti-misoperation bump 1121 and the second anti-misoperation bump 1122 are arranged side by side between two different mounting portions 113, with the first anti-misoperation bump 1121 located in the middle of the base 111 and the second anti-misoperation bump 1122 located at one end of the base 111. It can be understood that by setting the first anti-misoperation bump 1121 in the middle of the top surface of the base 111 and the second anti-misoperation bump 1122 at one end of the top surface of the base 111, the side-by-side arrangement of the first anti-misoperation bump 1121 and the second anti-misoperation bump 1122 forms a dual anti-misoperation mechanism. This not only effectively prevents the plug from being inserted backwards or incorrectly, making the connector plug insertion process more intuitive and simple, but also eliminates the need for users to worry about incorrect insertion direction or position, avoiding the possibility of electrical short circuits or equipment damage caused by misoperation. This improves the safety and reliability of the connector socket 100 and enhances the user experience.

[0043] In some embodiments, such as Figures 1 to 3 As shown, the first anti-mistake bump 1121 and the second anti-mistake bump 1122 have different shapes, and the width of the first anti-mistake bump 1121 is greater than the width of the second anti-mistake bump 1122. It is understood that the widths of the first anti-mistake bump 1121 and the second anti-mistake bump 1122 can be different; the first anti-mistake bump 1121 may have a larger width, for example, 3 mm, while the second anti-mistake bump 1122 may have a smaller width, for example, 2 mm. Furthermore, the first anti-mistake bump 1121 and the second anti-mistake bump 1122 can be rectangular in shape, and both are integrally injection molded with the base 111. This ensures that the connector plug must simultaneously match both anti-mistake bumps 112 for correct insertion, thus achieving a dual anti-mistake mechanism. This improves the anti-mistake effect of the connector socket 100, effectively preventing the connector plug from being inserted backwards or incorrectly, and enhancing the safety and reliability of the connector socket 100.

[0044] In some embodiments, such as Figure 2As shown, the mounting portion 113 has a mounting hole 1131. The second insert connecting portion 122 is inserted into the mounting hole 1131 and mounted on the mounting portion 113, such that the height of the socket insert 120 is greater than the height of the first anti-fooling protrusion 1121 and the second anti-fooling protrusion 1122. It is understood that by providing the mounting hole 1131 on the mounting portion 113 to accommodate and fix the second connecting portion of the socket insert 120, specifically, the shape and size of the mounting hole 1131 match the second connecting portion of the socket insert 120, for example, by being rectangular, ensuring that the insert can be securely installed. Furthermore, the second insert connecting portion 122 of the socket insert 120, as part of the socket insert 120, is installed in these mounting holes 1131 by insertion, thereby fixing it to the mounting portion 113. Additionally, after installation, the socket insert 120 protrudes from the surface of the anti-fooling protrusion 112, so that when the connector plug is inserted, the socket insert 120 can first contact the connector plug, ensuring the stability and reliability of the electrical connection. The height of the foolproof bump 112 is lower than that of the socket prong 120, which allows the connector plug to more accurately engage with the foolproof bump 112 during insertion, further enhancing the reliability of the foolproof function.

[0045] In some embodiments, such as Figure 2 As shown, the socket body 110 also includes a first positioning groove 114 located in the middle of the base 111 and a second positioning groove 115 located at one end of the base 111 and adjacent to the second anti-fooling protrusion 1122. The first positioning groove 114 and the second positioning groove 115 are used for guiding and positioning when the connector socket 100 is mated with the connector plug. It can be understood that the base 111 of the socket body 110 has two positioning grooves, wherein the first positioning groove 114 is located in the middle of the base 111, and the second positioning groove 115 is located at one end of the base 111 and adjacent to the second anti-fooling protrusion 1122. The first positioning groove 114 and the second positioning groove 115 provide a clear guiding path for the connector plug insertion. During plug insertion, the positioning grooves cooperate with the corresponding protrusions or structures on the connector plug, reducing the shaking and offset of the connector plug during insertion, allowing the connector plug to be inserted into the connector socket 100 more smoothly, guiding the connector plug to be correctly inserted into the connector socket 100, and ensuring precise mating between the connector plug and the connector socket 100, thus improving the user experience.

[0046] In some embodiments, such as Figure 3 and Figure 4As shown, the socket body 110 also includes a plurality of reinforcing ribs 116 disposed on the bottom surface of the base 111, with the reinforcing ribs 116 arranged side-by-side and spaced apart between each of the second plug-in connecting portions 122. It can be understood that the bottom surface of the base 111 of the socket body 110 is provided with a plurality of reinforcing ribs 116, which are arranged side-by-side and spaced apart between each of the second plug-in connecting portions 122. For example, if the socket body 110 is equipped with four socket plugs 120, and the corresponding four second plug-in connecting portions 122 pass through the bottom surface of the base 111, then a reinforcing rib 116 is provided between every two second plug-in connecting portions 122, meaning that the bottom surface of the base 111 can have a total of three reinforcing ribs 116. Furthermore, the material of the reinforcing ribs 116 can be the same as that of the base 111, both being integrally formed from plastic. By incorporating reinforcing ribs 116, the bending and torsional resistance of the base 111 can be improved. Especially when the connector socket 100 is frequently inserted and removed or subjected to external impact, it can effectively prevent the base 111 from deforming or being damaged, thus improving the durability of the connector socket 100. Furthermore, the reinforcing ribs 116 are arranged side-by-side at intervals between the second insert connecting portions 122, which can fully utilize the space on the bottom surface of the base 111, enhancing structural strength while avoiding interference with the installation and function of the inserts.

[0047] In some embodiments, such as Figure 1 , Figure 3 and Figure 4 As shown, the socket body 110 also includes a positioning post 117 disposed on the bottom surface of the base 111, wherein the positioning post 117 is connected to at least one reinforcing rib 116. It is understood that the positioning post 117 is connected to the intermediate reinforcing rib 116 via a mechanical connection (such as welding or injection molding). By providing the positioning post 117 on the bottom surface of the base 111, a precise reference point can be provided for the assembly of the connector socket 100. For example, when mounting the connector socket 100 on a circuit board, the positioning post 117 can ensure that the connector socket 100 is accurately aligned and fixed in the designated position, reducing errors during the assembly process. Simultaneously, the positioning post 117 and the reinforcing rib 116 are connected to form an integral structure, improving the mechanical strength and stability of the base 111, effectively preventing deformation or damage to the base 111 during use, and extending the service life of the connector socket 100.

[0048] In some embodiments, such as Figure 4As shown, the socket body 110 also includes a plurality of heat dissipation holes 118 disposed on the bottom surface of the base 111, with the heat dissipation holes 118 extending toward the top surface of the base 111. It is understood that the various heat dissipation holes 118 disposed on the bottom surface of the base 111 can be of the same size or different sizes. The heat dissipation holes 118 extend from the bottom surface to a position near the top surface, forming a good airflow channel, which can improve the heat dissipation efficiency of the connector socket 100, reduce the temperature of the connector socket 100 during use, and thus extend the service life of the connector socket 100.

[0049] Secondly, such as Figure 5 As shown, this application embodiment also provides a connection device, including: a connector plug 200 and a connector socket 100 of any embodiment of the first aspect.

[0050] In some embodiments, specifically as follows Figure 6 As shown, this application embodiment provides a connector plug 200 for mating with a connector socket 100 to achieve electrical connection. The connector plug 200 includes: a plug body 210, the plug body 210 having a foolproof groove 211 for preventing mis-mating of the connector socket 100; and a plug connection terminal 220, the rear end 221 of the plug connection terminal 220 being used for connecting to a cable, and the front end 222 of the plug connection terminal 220 having a locking part 2221 that cooperates with the connector socket 100 to achieve a locking connection.

[0051] It should be noted that the plug body 210 is the main part of the connector plug 200, and can be integrally injection molded. It supports and fixes the plug connection terminals 220, and the surface of the plug body 210 is provided with a foolproof groove 211 to mate with the corresponding connector socket 100 and prevent mis-connection. Further, as... Figure 6 As shown, the plug connection terminal 220 is divided into a front end 222 and a rear end 221. The rear end 221 adopts a standard interface design, which can be a soldered or crimped interface, making it easy to connect to a cable. The front end 222 is provided with a locking part 2221, which is used to cooperate with the corresponding connector socket 100 to achieve a stable locking connection.

[0052] In one embodiment, such as Figure 7 As shown, the locking part 2221 can be a protrusion structure formed on the front end 222. The socket insert 120 of the connector socket 100 is provided with a locking hole 1211. When the connector plug 200 is inserted into the connector socket 100, the locking part 2221 can be locked with the locking hole 1211, thereby improving the connection stability between the connector plug 200 and the connector socket 100.

[0053] Understandably, when the connector plug 200 is inserted into the connector socket 100, the locking part 2221 at the front end 222 of the plug connection terminal 220 engages with the socket insert 120 of the connector socket to directly lock the connection, achieving an efficient and stable connection and improving the connection stability between the connector plug 200 and the connector socket 100. Simultaneously, the plug body 210 is provided with a foolproof groove 211, which effectively prevents the connector plug 200 from being inserted backwards. This not only avoids electrical short circuits and equipment damage caused by misoperation but also provides strong compatibility and enhances the user experience.

[0054] In some embodiments, such as Figure 6 As shown, the plug body 210 has multiple accommodating cavities 212 arranged side-by-side inside, allowing each plug connection terminal 220 to pass through. It is understood that each accommodating cavity 212 is used to accommodate one plug connection terminal 220. In one embodiment, the plug body 210 may have four accommodating cavities 212, meaning that the plug body 210 can accommodate a maximum of four plug connection terminals 220. The size of the accommodating cavity 212 matches the shape and size of the plug connection terminal 220, allowing the plug connection terminal 220 to be fixed within the accommodating cavity 212 by crimping or welding, ensuring its stability and conductivity within the plug body 210. Furthermore, the consistent spacing between each accommodating cavity 212 ensures the uniform distribution of the plug connection terminals 220 within the plug body 210. This not only improves the structural stability of the connector plug 200 but also ensures electrical isolation between the plug connection terminals 220, reducing the risk of electrical interference or short circuits caused by inconsistent distances between the plug connection terminals 220 and improving the electrical performance of the connector plug 200.

[0055] In some embodiments, such as Figure 6 and Figure 8 As shown, the anti-mistake groove 211 includes a first anti-mistake groove 2111 and a second anti-mistake groove 2112. The first anti-mistake groove 2111 and the second anti-mistake groove 2112 are arranged side by side between two different receiving cavities 212. The width of the first anti-mistake groove 2111 is greater than the width of the second anti-mistake groove 2112.

[0056] It is understood that there are two anti-foolproof grooves 211 provided on the plug body 210: a first anti-foolproof groove 2111 and a second anti-foolproof groove 2112. These two anti-foolproof grooves 211 are arranged side by side between two different receiving cavities 212, and the width of the first anti-foolproof groove 2111 is greater than the width of the second anti-foolproof groove 2112. For example, the width of the first anti-foolproof groove 2111 is 5 mm, and the width of the second anti-foolproof groove 2112 is 3 mm. The depth of the first anti-foolproof groove 2111 and the second anti-foolproof groove 2112 can be the same, for example, both are set to a depth of 10 mm. The specific groove width values ​​are not limited in this embodiment. The first anti-misplacement groove 2111 and the second anti-misplacement groove 2112 have different widths, requiring simultaneous matching of two different width anti-misplacement structures in the connector socket 100, forming a dual anti-misplacement mechanism. When inserting the connector plug 200, the user can quickly determine whether the orientation of the connector plug 200 is correct by touch or sight, effectively preventing the connector plug 200 from being inserted backwards or incorrectly, avoiding electrical short circuits or equipment damage caused by misoperation, and significantly improving the safety and reliability of the connector plug 200. In addition, the different widths of the first anti-misplacement groove 2111 and the second anti-misplacement groove 2112 allow the connector plug 200 to match with connector sockets 100 of specific structures, while not affecting compatibility with other standard sockets.

[0057] In some embodiments, such as Figure 7 As shown, the front end portion 222 includes a bottom wall 2222, two side walls 2223 extending upward from the left and right sides of the bottom wall 2222, and two top walls 2224 bending inward from the two side walls 2223. The bottom wall 2222, the two side walls 2223, and the two top walls 2224 together define a slot 2220 for the socket insert 120 of the connector socket 100 to be inserted. A locking part 2221 is provided on the bottom wall 2222, and the socket insert 120 is provided with a locking hole 1211 corresponding to the locking part 2221.

[0058] Understandably, the two side walls 2223 are formed by bending upwards from the left and right sides of the bottom wall 2222, and the top wall 2224 is formed by bending inwards from the two side walls 2223 respectively. After the socket prong 120 is inserted into the slot 2220, the locking part 2221 falls into the locking hole 1211, thus locking the socket. Furthermore, the middle area of ​​the two top walls 2224 is recessed towards the bottom wall 2222, making the fit between the slot 2220 and the socket prong 120 even tighter.

[0059] In some embodiments, such as Figure 9 As shown, the accommodating cavity 212 is provided with two elastic pressure blocks 2121, which are respectively corresponding to the top wall 2224.

[0060] Understandably, the elastic pressure block 2121 guides the front end 222 of the plug connection terminal 220 into the receiving cavity 212, providing initial positioning and support. This helps reduce friction and resistance when the plug connection terminal 220 is inserted into the receiving cavity 212, making the installation of the plug connection terminal 220 smoother and improving assembly efficiency. Furthermore, as... Figure 7 As shown, when the connector plug 200 and the connector socket 100 are assembled together so that the socket prong 120 of the connector socket 100 is inserted into the slot 2220, the elastic pressure block 2121 presses against the top wall 2224 so that the top wall 2224 presses the socket prong 120 tightly, so that the socket prong 120 is close to the bottom wall 2222, preventing the socket prong 120 from easily falling off when it is directly pulled out.

[0061] In some embodiments, such as Figure 7 and Figure 9 As shown, the bottom wall 2222 is provided with an elastic member 2225 with a rebound force. The elastic member 2225 extends obliquely towards the top wall to form a pressing part 2226. The locking part 2221 is provided on the elastic member 2225. The receiving cavity 212 is also provided with an unlocking protrusion 2122 corresponding to the pressing part 2226.

[0062] Understandably, with the above structure, when the connector plug 200 is pulled out of the connector socket 100, the unlocking protrusion 2122 pushes the pressing part 2226, so that the pressing part 2226 drives the elastic member 2225 away from the socket insert 120, so that the locking part 2221 disengages from the locking hole 1211, and thus the plug body 110 of the connector plug 200 together with the plug connection terminal 220 installed inside the plug body 110 can be smoothly pulled out of the connector socket 100.

[0063] It should be noted that by further precisely positioning and restricting the installation position of the plug connection terminal 220 by unlocking the protrusion 2122, the plug connection terminal 220 can be prevented from falling out of the port of the accommodating cavity 212, reducing the risk of poor contact or unstable connection of the plug connection terminal 220 due to positional deviation, and improving the reliability of the connector plug 200 connection.

[0064] In one embodiment, such as Figure 7 As shown, there is a gap between the two top walls 2224. Through the gap, the unlocking protrusion 2122 and the elastic pressure block 2121 in the receiving cavity 212 can be used to guide the plug connection terminal 220 to be correctly assembled into the receiving cavity 212. This not only improves the assembly accuracy of the connector plug 200 and the connector socket 100, but also ensures the stability of the electrical connection.

[0065] More specifically, in combination Figure 1 , Figure 6 and Figure 7 As shown, when Figure 6 The connector plug 200 shown is inserted downwards in the direction illustrated. Figure 1 After the connector socket 100 is installed, the socket prong 120 is inserted into the slot 2220 of the plug connection terminal 220, and the locking part 2221 of the plug connection terminal 220 is located inside the locking hole 1211 of the socket prong 120. Under the pressing action of the two top walls 2224 of the front end 222 on the socket prong 120, the socket prong 120 is tightly attached to the bottom wall 2222; Figure 7 At this time, even if the plug connection terminal 220 is pulled upwards directly, the locking part 2221 will press against the inner wall of the locking hole 1211 and cannot disengage, so that the plug connection terminal 220 and the socket prong 120 will not easily disengage.

[0066] When it is necessary to unplug the connector plug 200 from the connector socket 100, combined with Figure 6 When the user holds the plug body 210 of the connector plug 200 and pulls it upward, the plug connection terminal 220 inside the plug body 210 will not move. The plug body 210 will undergo a first upward displacement relative to the plug connection terminal 220 and the connector socket 100, combined with... Figure 9 The unlocking protrusion 2122 inside the accommodating cavity 212 of the plug body 210 also undergoes a first upward displacement, and the unlocking protrusion 2122 pushes upward against the pressing part 2226 on the plug connection terminal 220. Figure 9 The unlocking bumps 2122 shown are paired Figure 7 Under the pushing action of the pressing part 2226 shown, the elastic member 2225 moves away from the socket insert 120, thereby causing the locking part 2221 on the plug connection terminal 220 to disengage from the locking hole 1211 of the socket insert 120, and the plug connection terminal 220 and the socket insert 120 are no longer locked together, thus unlocking the plug connection terminal 220 and the socket insert 120; the user continues to drive the plug body 210 upward to produce a second displacement, and the plug body 210 drives the internal connection terminal 220 to move upward, thereby disengaging from the socket insert 120 on the connector socket 100.

[0067] In some embodiments, such as Figure 7 As shown, the rear end portion 221 includes a core riveting roll 2211 and a sheath riveting roll 2212, wherein the core riveting roll 2211 is disposed near the front end portion 222. Specifically, the core riveting roll 2211 can be used to connect with the conductive core of the cable (not shown in the figure) to ensure the stability of the electrical connection. The sheath riveting roll 2212 can be used to connect with the insulating sheath of the cable (not shown in the figure), providing mechanical support and fixing the cable, preventing the cable from loosening or falling out inside the connector plug 200, and improving the connection strength between the connector plug 200 and the cable.

[0068] In some embodiments, such as Figure 7 As shown, the center lines of the slot 2220, the wire core riveting roll 2211, and the wire sheath riveting roll 2212 are aligned on the same straight line. It is understood that to ensure the overall structural alignment and stability of the connector plug 200, the center lines of the slot 2220, the wire core riveting roll 2211, and the wire sheath riveting roll 2212 are aligned on the same straight line. For example, the center line of the slot 2220 is located at the geometric center of the plug connection terminal 220, and the center lines of the wire core riveting roll 2211 and the wire sheath riveting roll 2212 are also precisely aligned to this center line, ensuring good alignment of the plug connection terminal 220 when inserted into the connector socket 100, reducing poor contact or assembly difficulties caused by structural deviations.

[0069] In some embodiments, such as Figure 6 and Figure 8 As shown, the plug body 210 also includes a plurality of connecting grooves 213 corresponding to the port positions of the receiving cavity 212, and the spacing between each connecting groove 213 is consistent.

[0070] It is understood that the plug body 210 also has multiple connecting grooves 213 on its surface. The positions of the connecting grooves 213 correspond one-to-one with the port positions of the receiving cavities 212, ensuring that the plug connecting terminals 220 can be accurately aligned when mating with the socket prongs, reducing poor contact or loose connection problems caused by positional deviations, thereby improving the stability and reliability of the connection. Specifically, the plug body 210 has four receiving cavities 212 inside, and each receiving cavity 212 has a corresponding connecting groove 213 at its port. The spacing between the connecting grooves 213 is consistent, that is, consistent with the spacing between the corresponding receiving cavities 212. In one embodiment, the width of the connecting groove 213 is smaller than the width of the first anti-foolproof groove 2111 and the second anti-foolproof groove 2112. For example, the width of the first anti-foolproof groove 2111 is 5 mm, the width of the second anti-foolproof groove 2112 is 3 mm, and the width of the connecting groove 213 can be set to 2 mm. The depth of the connecting groove 213 is less than the depth of the first anti-foolproof groove 2111 and the second anti-foolproof groove 2112, ensuring that the connecting groove 213 can be tightly engaged with the mating structure of the connector socket 100, thereby improving the stability of the connector plug 200 connection.

[0071] In some embodiments, such as Figure 6 and Figure 8 As shown, the front wall of the plug body 210 is provided with a first positioning protrusion 214 and a second positioning protrusion 215. The first positioning protrusion 214 and the second positioning protrusion 215 are used for guiding and positioning when the connector plug 200 mates with the connector socket 100.

[0072] It is understood that the protrusion structure provided on the front wall of the plug body 210 includes a first positioning protrusion 214 and a second positioning protrusion 215. In one embodiment, the first positioning protrusion 214 is located near the first anti-foolproof groove 2111, and the second positioning protrusion 215 is located near the second anti-foolproof groove 2112. This allows the first positioning protrusion 214 and the second positioning protrusion 215 to engage with corresponding structures on the connector socket 100 when the connector plug 200 is inserted into the connector socket 100. For example, the connector socket 100 may have corresponding groove structures, reducing the shaking and offset of the connector plug 200 during insertion. This allows the connector plug 200 to be inserted into the connector socket 100 more smoothly and ensures precise mating between the connector plug 200 and the connector socket 100, improving the user experience.
