[0001] This application relates to the field of electrical connector technology, and in particular to a connector plug and 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 plugged in and socket connected, current or signals are transmitted, enabling connection and communication between electrical devices. In the field of high-voltage plugs, the RAST (Rapid Action Self-locking Terminal) structure is a common quick-connect and locking technology. Currently used RAST plugs lock to the socket via a 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 plug and a connecting device, which not only improves the connection stability between the connector plug and the connector socket, but also effectively prevents the connector plug from being inserted in reverse, thereby enhancing the user experience.

[0014] According to some embodiments of the present invention, when the connector plug is pulled out of the connector socket, the unlocking protrusion pushes the pressing part so that the pressing part drives the elastic member away from the socket insert, thereby disengaging the locking part from the locking hole.

[0015] According to some embodiments of the present invention, the connector plug includes a wire core riveting roll and a wire sheath riveting roll at the rear end, wherein the wire core riveting roll is disposed close to the front end.

[0016] According to some embodiments of the present invention, the connector plug body further includes a plurality of connecting grooves corresponding to the port positions of the receiving cavity, and the spacing between each connecting groove is consistent.

[0037] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0038] The embodiments of this application will be further described below with reference to the accompanying drawings.

[0039] Firstly, such as Figures 1 to 2 As shown, this application embodiment provides a connector plug 100 for mating with a connector socket to achieve electrical connection. The connector plug 100 includes: a plug body 110 and a plug connection terminal 120, wherein: the plug body 110 is provided with a foolproof groove 111 for preventing mis-mating of the connector socket; the rear end 121 of the plug connection terminal 120 is used for connecting with a cable, and the front end 122 of the plug connection terminal 120 is provided with a locking part 1221 that cooperates with the connector socket to achieve a locking connection.

[0040] It should be noted that the plug body 110 is the main part of the connector plug 100, and can be integrally injection molded. It supports and fixes the plug connection terminals 120, and the surface of the plug body 110 is provided with a foolproof groove 111 for mating with the corresponding connector socket to prevent mis-connection. Further, as... Figure 1 As shown, the plug connection terminal 120 is divided into a front end 122 and a rear end 121. The rear end 121 adopts a standard interface design, which can be a soldered or crimped interface, making it easy to connect to a cable. The front end 122 is provided with a locking part 1221, which is used to cooperate with the corresponding connector socket to achieve a stable locking connection.

[0041] Understandably, when the connector plug 100 is inserted into the connector socket, the locking part 1221 at the front end 122 of the plug connection terminal 120 engages with the insert of the connector socket to directly lock the connection, achieving an efficient and stable connection and improving the connection stability between the connector plug 100 and the connector socket. Simultaneously, the plug body 110 is provided with a foolproof groove 111, which effectively prevents the connector plug 100 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.

[0042] In some embodiments, such as Figure 1 As shown, the plug body 110 has multiple accommodating cavities 112 arranged side-by-side inside, allowing each plug connection terminal 120 to pass through. It is understood that each accommodating cavity 112 is used to accommodate one plug connection terminal 120. In one embodiment, the plug body 110 may have four accommodating cavities 112, meaning that the plug body 110 can accommodate a maximum of four plug connection terminals 120. The size of the accommodating cavity 112 matches the shape and size of the plug connection terminal 120, thereby fixing the plug connection terminal 120 within the accommodating cavity 112 by crimping or welding, ensuring its stability and conductivity within the plug body 110. Furthermore, the consistent spacing between each accommodating cavity 112 ensures the uniform distribution of the plug connection terminals 120 within the plug body 110. This not only improves the structural stability of the connector plug 100 but also ensures electrical isolation between the plug connection terminals 120, reducing the risk of electrical interference or short circuits caused by inconsistent distances between the plug connection terminals 120 and improving the electrical performance of the connector plug 100.

[0043] In some embodiments, such as Figure 1 and Figure 2 As shown, the anti-mistake groove 111 includes a first anti-mistake groove 1111 and a second anti-mistake groove 1112. The first anti-mistake groove 1111 and the second anti-mistake groove 1112 are arranged side by side between two different receiving cavities 112. The width of the first anti-mistake groove 1111 is greater than the width of the second anti-mistake groove 1112.

[0044] It is understood that there are two anti-foolproof grooves 111 provided on the plug body 110: a first anti-foolproof groove 1111 and a second anti-foolproof groove 1112. These two anti-foolproof grooves 111 are arranged side by side between two different receiving cavities 112, and the width of the first anti-foolproof groove 1111 is greater than the width of the second anti-foolproof groove 1112. For example, the width of the first anti-foolproof groove 1111 is 5 mm, and the width of the second anti-foolproof groove 1112 is 3 mm. The depth of the first anti-foolproof groove 1111 and the second anti-foolproof groove 1112 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 1111 and the second anti-misplacement groove 1112 have different widths, requiring simultaneous matching of two different width anti-misplacement structures in the connector socket, forming a dual anti-misplacement mechanism. When inserting the connector plug 100, the user can quickly determine whether the orientation of the connector plug 100 is correct by touch or sight, effectively preventing the connector plug 100 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 100. In addition, the different widths of the first anti-misplacement groove 1111 and the second anti-misplacement groove 1112 allow the connector plug 100 to match connector sockets with specific structures, while not affecting compatibility with other standard sockets.

[0045] In some embodiments, such as Figure 6 As shown, the front end portion 122 includes a bottom wall 1222, two side walls 1223 extending upward from the left and right sides of the bottom wall 1222, and two top walls 1224 bending inward from the two side walls 1223. The bottom wall 1222, the two side walls 1223, and the two top walls 1224 together define a slot 1220 for the socket insert 220 of the connector socket 200 to be inserted. A locking part 1221 is provided on the bottom wall 1222, and the socket insert 220 is provided with a locking hole 2211 corresponding to the locking part 1221.

[0046] Understandably, the two side walls 1223 are formed by bending upwards from the left and right sides of the bottom wall 1222, and the top wall 1224 is formed by bending the two side walls 1223 inwards respectively. After the socket prong 220 is inserted into the slot 1220, the locking part 1221 falls into the locking hole 2211, thus locking. Furthermore, the middle area of ​​the two top walls 1224 is recessed towards the bottom wall 1222, making the fit between the slot 1220 and the socket prong 220 even tighter.

[0047] In some embodiments, such as Figure 3 As shown, the accommodating cavity 112 is provided with two elastic pressure blocks 1121, which are respectively corresponding to the top wall 1224.

[0048] Understandably, the elastic pressure block 1121 guides the front end 122 of the plug connection terminal 120 into the receiving cavity 112, providing initial positioning and support. This helps reduce friction and resistance when the plug connection terminal 120 is inserted into the receiving cavity 112, making the installation of the plug connection terminal 120 smoother and improving assembly efficiency. Furthermore, as... Figure 6 As shown, when the connector plug 100 and the connector socket 200 are assembled together so that the socket prong 220 of the connector socket 200 is inserted into the slot 1220, the elastic pressure block 1121 presses against the top wall 1224 so that the top wall 1224 presses the socket prong 220 tightly, so that the socket prong 220 is close to the bottom wall 1222, preventing the socket prong 220 from easily falling off when it is directly pulled out.

[0049] In some embodiments, such as Figure 3 and Figure 6 As shown, the bottom wall 1222 is provided with an elastic member 1225 with a rebound force. The elastic member 1225 extends obliquely towards the top wall to form a pressing part 1226. A locking part 1221 is provided on the elastic member 1225. The receiving cavity 112 is also provided with an unlocking protrusion 1122 corresponding to the pressing part 1226.

[0050] Understandably, with the above structure, when the connector plug 100 is pulled out of the connector socket 200, the unlocking protrusion 1122 pushes the pressing part 1226, so that the pressing part 1226 drives the elastic member 1225 away from the socket insert 220, so that the locking part 1221 disengages from the locking hole 2211, and thus the plug body 110 of the connector plug 100 together with the plug connection terminal 120 installed inside the plug body 110 can be smoothly pulled out of the connector socket 200.

[0051] It should be noted that by further precisely positioning and restricting the installation position of the plug connection terminal 120 by unlocking the protrusion 1122, the plug connection terminal 120 can be prevented from falling out of the port of the accommodating cavity 112, reducing the risk of poor contact or unstable connection of the plug connection terminal 120 due to positional deviation, and improving the reliability of the connector plug 100 connection.

[0052] In one embodiment, such as Figure 6 As shown, a gap is left between the two top walls 1224. Through the gap, the unlocking protrusion 1122 and the elastic pressure block 1121 in the receiving cavity 112 can be used to guide the plug connection terminal 120 to be correctly assembled into the receiving cavity 112. This not only improves the assembly accuracy of the connector plug 100 and the connector socket 200, but also ensures the stability of the electrical connection.

[0053] In some embodiments, such as Figure 6As shown, the rear end portion 121 includes a core riveting roll 1211 and a sheath riveting roll 1212, wherein the core riveting roll 1211 is disposed near the front end portion 122. Specifically, the core riveting roll 1211 can be used to connect with the conductive core of a cable (not shown in the figure) to ensure the stability of the electrical connection. The sheath riveting roll 1212 can be used to connect with the insulating sheath of a 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 100, and improving the connection strength between the connector plug 100 and the cable.

[0054] In some embodiments, such as Figure 6 As shown, the center lines of the slot 1220, the wire core riveting roll 1211, and the wire sheath riveting roll 1212 are aligned on the same straight line. It is understood that to ensure the overall structural alignment and stability of the connector plug 100, the center lines of the slot 1220, the wire core riveting roll 1211, and the wire sheath riveting roll 1212 are aligned on the same straight line. For example, the center line of the slot 1220 is located at the geometric center of the plug connection terminal 120, and the center lines of the wire core riveting roll 1211 and the wire sheath riveting roll 1212 are also precisely aligned to this center line, ensuring good alignment of the plug connection terminal 120 when inserted into the connector socket 200, reducing poor contact or assembly difficulties caused by structural deviations.

[0055] In some embodiments, such as Figure 1 and Figure 2 As shown, the plug body 110 also includes a plurality of connecting grooves 113 corresponding to the port positions of the receiving cavity 112, and the spacing between each connecting groove 113 is consistent.

[0056] It is understood that the surface of the plug body 110 is also provided with multiple connecting grooves 113. The positions of the connecting grooves 113 correspond one-to-one with the port positions of the receiving cavities 112, ensuring that the plug connecting terminals 120 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 110 has four receiving cavities 112 inside, and a connecting groove 113 is provided at the port of each receiving cavity 112. The spacing between the connecting grooves 113 is consistent, that is, consistent with the spacing between the corresponding receiving cavities 112. In one embodiment, the width of the connecting groove 113 is smaller than the width of the first anti-foolproof groove 1111 and the second anti-foolproof groove 1112. For example, the width of the first anti-foolproof groove 1111 is 5 mm, the width of the second anti-foolproof groove 1112 is 3 mm, and the width of the connecting groove 113 can be set to 2 mm. The depth of the connecting groove 113 is less than the depth of the first anti-foolproof groove 1111 and the second anti-foolproof groove 1112, ensuring that the connecting groove 113 can be tightly engaged with the mating structure of the connector socket 200, thereby improving the stability of the connector plug 100 connection.

[0057] In some embodiments, such as Figure 1 and Figure 2 As shown, the front wall of the plug body 110 is provided with a first positioning protrusion 114 and a second positioning protrusion 115. The first positioning protrusion 114 and the second positioning protrusion 115 are used for guiding and positioning when the connector plug 100 and the connector socket 200 are mated.

[0058] It is understood that the protrusion structure provided on the front wall of the plug body 110 includes a first positioning protrusion 114 and a second positioning protrusion 115. In one embodiment, the first positioning protrusion 114 is located near the first anti-foolproof groove 1111, and the second positioning protrusion 115 is located near the second anti-foolproof groove 1112. This allows the first positioning protrusion 114 and the second positioning protrusion 115 to engage with corresponding structures on the connector socket 200 when the connector plug 100 is inserted into the connector socket 200. For example, the connector socket 200 may have corresponding groove structures, reducing the shaking and offset of the connector plug 100 during insertion. This allows the connector plug 100 to be inserted into the connector socket 200 more smoothly and ensures precise mating between the connector plug 100 and the connector socket 200, improving the user experience.

[0059] Secondly, such as Figure 4 As shown, this application embodiment also provides a connection device, including: a connector socket 200 and a connector plug 100 of any embodiment of the first aspect.

[0060] In some embodiments, specifically as follows Figure 5As shown, this application embodiment provides a connector socket 200, which is fixedly installed on a circuit board and used to mate with a connector plug 100 to achieve electrical connection. The connector socket 200 includes: a socket body 210, which includes a base 211 and a foolproof protrusion 212 disposed on the top surface of the base 211. The foolproof protrusion 212 is used to prevent mis-interaction of the connector plug 100; a socket insert 220, which passes through the base 211 and extends from the top surface of the base 211 with a first insert connecting portion 221 and from the bottom surface of the base 211 with a second insert connecting portion 222. The second insert connecting portion 222 is used to insert into the circuit board and achieve electrical connection with the circuit board. The first insert connecting portion 221 has a locking hole 2211 for cooperating with the connector plug 100 to achieve a locking connection.

[0061] It should be noted that a foolproof protrusion 212 is provided on the top surface of the base 211 to prevent mis-interlocking of the connector plug 100, ensuring that the connector plug 100 can only be inserted in the correct manner. Further, as... Figure 4 As shown, the socket insert 220 of the connector socket 200 passes through the base 211 during assembly. The first insert connecting part 221 extends from the top surface of the base 211, and the second insert connecting part 222 extends from the bottom surface of the base 211. The second insert connecting part 222 is used to insert into the circuit board and realize electrical connection. The first insert connecting part 221 is provided with a locking hole 2211.

[0062] In one embodiment, such as Figure 6 As shown, when the connector plug 100 is inserted into the connector socket 200, the locking part 1221 engages with the locking hole 2211 provided on the socket insert 220 of the connector socket 200, and the locking part 1221 can be locked with the locking hole 2211. When the connector plug 100 is pulled out of the connector socket, the unlocking protrusion 1122 first presses the pressing part 1226, that is, the unlocking protrusion 1122 applies pressure to the pressing part 1226 in the same direction as pulling out, so that the locking part 1221 on the elastic member 1225 disengages from the locking hole 2211 on the socket insert 220, thereby unlocking, and then the plug body 110 of the connector plug 100 together with the plug connection terminal 120 installed inside the plug body 110 can be smoothly pulled out of the connector socket 200.

[0063] More specifically, combined Figure 1 , Figure 5 and Figure 6 As shown, when Figure 1 The connector plug 100 shown is inserted downwards in the direction illustrated. Figure 5After the connector socket 200 is installed, the socket prong 220 is inserted into the slot 1220 of the plug connection terminal 120, and the locking part 1221 of the plug connection terminal 120 is located inside the locking hole 2211 of the socket prong 220. Under the pressing action of the two top walls 1224 of the front end 222 on the socket prong 220, the socket prong 220 is tightly attached to the bottom wall 1222; Figure 6 At this time, even if the plug connection terminal 120 is pulled upwards directly, the locking part 1221 will press against the inner wall of the locking hole 2211 and cannot disengage, so that the plug connection terminal 120 and the socket prong 220 will not easily disengage.

[0064] When it is necessary to unplug the connector plug 100 from the connector socket 200, combined with Figure 1 When the user holds the plug body 110 of the connector plug 100 and pulls it upward, the plug connection terminal 120 inside the plug body 110 will not move. The plug body 110 will undergo a first upward displacement relative to the plug connection terminal 120 and the connector socket 200, thus combining... Figure 3 The unlocking protrusion 1122 inside the plug body 110 also undergoes a first upward displacement, and the unlocking protrusion 1122 pushes upward against the pressing part 1226 on the plug connection terminal 120. Figure 3 The unlocking bumps 1122 shown are paired Figure 6 Under the pushing action of the pressing part 1226 shown, the elastic member 1225 moves away from the socket insert 220, thereby causing the locking part 1221 on the plug connection terminal 120 to disengage from the locking hole 2211 of the socket insert 220, and the plug connection terminal 120 and the socket insert 220 are no longer locked together, thus unlocking the plug connection terminal 120 and the socket insert 220; the user continues to drive the plug body 110 upward to produce a second displacement, and the plug body 110 drives the internal connection terminal 120 to move upward, thereby disengaging from the socket insert 220 on the connector socket 200.

[0065] Understandably, when the connector plug 100 is inserted into the connector socket 200, the socket prongs 220 engage with the plug connection terminals 120 of the connector plug 100 to directly lock together, achieving an efficient and stable connection and improving the connection stability between the connector socket 200 and the connector plug 100. Simultaneously, the socket body 210 is equipped with a foolproof protrusion 212, which effectively prevents the connector plug 100 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.

[0066] In some embodiments, such as Figure 7As shown, the socket body 210 has multiple mounting portions 213 arranged side-by-side inside, through which socket prongs 220 pass. The spacing between each mounting portion 213 is uniform. It is understood that each socket prong 220 passes through and is mounted on a mounting portion 213, ensuring stable installation and correct positioning of the socket prong 220. In one embodiment, the socket body 210 has four mounting portions 213, with equal spacing between each portion (e.g., 3 mm, 5 mm). Correspondingly, four socket prongs 220 are also provided, which can be fixed to the mounting portions 213 by snap-fit ​​or welding. Furthermore, the uniform distribution of the socket prongs 220 within the socket body 210 ensures the stability of current or signal transmission, avoiding poor contact or signal attenuation due to inconsistent prong positions. Additionally, when the connector plug 100 is inserted, the uniform distribution of the socket prongs 220 allows for smoother insertion, reducing resistance and sticking during insertion and removal, thus improving the user experience.

[0067] In some embodiments, the second insert connector 222 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 222 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 200 and the circuit board.

[0068] In some embodiments, such as Figure 5 , Figure 7 and Figure 8 As shown, the anti-misoperation bump 212 includes a first anti-misoperation bump 2121 and a second anti-misoperation bump 2122. The first anti-misoperation bump 2121 and the second anti-misoperation bump 2122 are arranged side by side between two different mounting portions 213, with the first anti-misoperation bump 2121 located in the middle of the base 211 and the second anti-misoperation bump 2122 located at one end of the base 211. It can be understood that by setting the first anti-misoperation bump 2121 in the middle of the top surface of the base 211 and the second anti-misoperation bump 2122 at one end of the top surface of the base 211, the side-by-side arrangement of the first anti-misoperation bump 2121 and the second anti-misoperation bump 2122 forms a dual anti-misoperation mechanism. This not only effectively prevents the plug from being inserted backwards or incorrectly, making the insertion process of the connector plug 100 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 200 and enhances the user experience.

[0069] In some embodiments, such as Figure 5 , Figure 7 and Figure 8 As shown, the first anti-mistake bump 2121 and the second anti-mistake bump 2122 have different shapes, and the width of the first anti-mistake bump 2121 is greater than the width of the second anti-mistake bump 2122. It is understood that the widths of the first anti-mistake bump 2121 and the second anti-mistake bump 2122 can be different; the first anti-mistake bump 2121 may have a larger width, for example, 3 mm, while the second anti-mistake bump 2122 may have a smaller width, for example, 2 mm. Furthermore, the first anti-mistake bump 2121 and the second anti-mistake bump 2122 can be rectangular in shape, and they are integrally injection molded with the base 211. This ensures that the connector plug 100 must simultaneously match both anti-mistake bumps 212 to be correctly inserted, thus achieving a dual anti-mistake mechanism. This improves the anti-mistake effect of the connector socket 200, effectively preventing the connector plug 100 from being inserted backwards or incorrectly, and enhancing the safety and reliability of the connector socket 200.

[0070] In some embodiments, such as Figure 7 As shown, the mounting portion 213 has mounting holes 2131. The second insert connecting portion 222 is inserted into the mounting holes 2131 and mounted on the mounting portion 213, such that the height of the socket insert 220 is greater than the height of the first anti-fooling protrusion 2121 and the second anti-fooling protrusion 2122. It can be understood that by providing mounting holes 2131 in the mounting portion 213 to accommodate and fix the second connecting portion of the socket insert 220, specifically, the shape and size of the mounting holes 2131 match the second connecting portion of the socket insert 220, for example, by being rectangular, ensuring that the insert can be securely installed. Furthermore, the second insert connecting portion 222 of the socket insert 220, as part of the socket insert 220, is installed in these mounting holes 2131 by insertion, thereby fixing it to the mounting portion 213. Furthermore, the socket prong 220 protrudes beyond the surface of the foolproof bump 212 after installation, ensuring that the socket prong 220 contacts the connector plug 100 first when it is inserted, thus guaranteeing the stability and reliability of the electrical connection. The height of the foolproof bump 212 is lower than that of the socket prong 220, allowing the connector plug 100 to more precisely engage with the foolproof bump 212 during insertion, further enhancing the reliability of the foolproof function.

[0071] In some embodiments, such as Figure 7As shown, the socket body 210 also includes a first positioning groove 214 disposed in the middle position of the base 211 and a second positioning groove 215 disposed at one end of the base 211 and located on one side of the second anti-fooling protrusion 2122. The first positioning groove 214 and the second positioning groove 215 are used for guiding and positioning when the connector socket 200 and the connector plug 100 are mated. Understandably, the base 211 of the socket body 210 is provided with two positioning grooves. The first positioning groove 214 is located in the middle of the base 211, and the second positioning groove 215 is located at one end of the base 211 and adjacent to the side of the second anti-fooling protrusion 2122. The first positioning groove 214 and the second positioning groove 215 provide a clear guiding path for the insertion of the connector plug 100. During the insertion process, the positioning grooves cooperate with the corresponding protrusions or structures on the connector plug 100 to reduce the shaking and offset of the connector plug 100 during insertion, so that the connector plug 100 can be inserted into the connector socket 200 more smoothly, guide the connector plug 100 to be correctly inserted into the connector socket 200, and ensure the precise docking of the connector plug 100 and the connector socket 200, thereby improving the user experience.

[0072] In some embodiments, such as Figure 8 and Figure 9 As shown, the socket body 210 also includes a plurality of reinforcing ribs 216 disposed on the bottom surface of the base 211, with the reinforcing ribs 216 arranged side-by-side and spaced apart between each of the second plug-in connecting portions 222. It can be understood that the bottom surface of the base 211 of the socket body 210 is provided with a plurality of reinforcing ribs 216, which are arranged side-by-side and spaced apart between each of the second plug-in connecting portions 222. For example, if the socket body 210 is equipped with four socket plugs 220, and the corresponding four second plug-in connecting portions 222 pass through the bottom surface of the base 211, then a reinforcing rib 216 is provided between every two second plug-in connecting portions 222, meaning that the bottom surface of the base 211 can have a total of three reinforcing ribs 216. Furthermore, the material of the reinforcing ribs 216 can be the same as that of the base 211, both being integrally formed from plastic. By incorporating reinforcing ribs 216, the bending and torsional resistance of the base 211 can be improved. Especially when the connector socket 200 is frequently plugged in and out or subjected to external impacts, it effectively prevents deformation or damage to the base 211, thus improving the durability of the connector socket 200. Furthermore, the reinforcing ribs 216 are arranged side-by-side at intervals between the second insert connection portions 222, which fully utilizes the space on the bottom surface of the base 211, enhancing structural strength while avoiding interference with the installation and function of the inserts.

[0073] In some embodiments, such as Figure 5 , Figure 8 and Figure 9As shown, the socket body 210 also includes a positioning post 217 disposed on the bottom surface of the base 211, wherein the positioning post 217 is connected to at least one reinforcing rib 216. It is understood that the positioning post 217 is connected to the intermediate reinforcing rib 216 via a mechanical connection (such as welding or injection molding). By providing the positioning post 217 on the bottom surface of the base 211, a precise reference point can be provided for the assembly of the connector socket 200. For example, when mounting the connector socket 200 on a circuit board, the positioning post 217 can ensure that the connector socket 200 is accurately aligned and fixed in the designated position, reducing errors during the assembly process. Simultaneously, the positioning post 217, connected to the reinforcing rib 216, forms an integral structure, improving the mechanical strength and stability of the base 211, effectively preventing deformation or damage to the base 211 during use, and extending the service life of the connector socket 200.

[0074] In some embodiments, such as Figure 9 As shown, the socket body 210 also includes a plurality of heat dissipation holes 218 disposed on the bottom surface of the base 211, with the heat dissipation holes 218 extending toward the top surface of the base 211. It is understood that the various heat dissipation holes 218 disposed on the bottom surface of the base 211 can be of the same size or different sizes. The heat dissipation holes 218 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 200, reduce the temperature of the connector socket 200 during use, and thus extend the service life of the connector socket 200.
