Description

Technical Field

[0001] The present application relates to the field of terminal technology, and in particular to an electrical connector and an electronic device including the electrical connector. Background Art

[0002] Corrosion of the signal terminals on electronic devices, such as mobile phones, can cause charging malfunctions during charging or signal transmission operations, and in severe cases, lead to safety issues such as interface melting. Therefore, it is crucial to mitigate or prevent corrosion of signal terminals on electronic connectors. Summary of the Invention

[0003] The present application provides an electrical connector and an electronic device including the electrical connector, which can reduce or even avoid corrosion of signal terminals of the electrical connector.

[0004] In a first aspect, the present application provides an electrical connector. The electrical connector includes a base, a tongue plate, and a first terminal, one end of the tongue plate being connected to the base. In some embodiments, the tongue plate being connected to the base may also mean that the tongue plate and the base are integrally formed. The tongue plate includes a first surface and a second surface disposed opposite each other, and the base includes a third surface and a fourth surface disposed opposite each other, the first surface and the third surface being located on the same side of the electrical connector, the second surface and the fourth surface being located on the same side of the electrical connector, and a projection of the tongue plate on a plane perpendicular to the third surface being located between the third and fourth surfaces. The first terminal includes a first contact segment and a first connecting segment, the first contact segment being at least partially embedded in the tongue plate and at least partially exposed from the first surface. The base includes a first notch, the first notch being located in the direction extending from the length of the first contact segment, the first notch including a first bottom surface connected to the first surface. The first connecting segment is connected to the first contact segment, the first connecting segment being at least partially embedded in the base and not exposed from the first bottom surface.

[0005] The first contact segment being at least partially exposed from the first surface can be a surface of the first contact segment facing away from the interior of the tongue plate that protrudes from the first surface, thereby partially exposing the first contact segment from the first surface. Alternatively, the first contact segment being at least partially exposed from the first surface can be a surface of the first contact segment facing away from the interior of the tongue plate that is flush with the first surface or slightly lower than the first surface, but the surface of the first contact segment facing away from the interior of the tongue plate is exposed. In other words, a strip groove can be recessed in the first surface of the tongue plate, the first contact segment is embedded in the strip groove, and the surface of the first contact segment facing away from the tongue plate is exposed. When the thickness of the first contact segment is greater than the depth of the strip groove, the surface of the first contact segment facing away from the interior of the tongue plate protrudes from the first surface; when the thickness of the first contact segment is equal to the depth of the strip groove, the surface of the first contact segment facing away from the interior of the tongue plate is flush with the first surface; when the thickness of the first contact segment is less than the depth of the strip groove, the surface of the first contact segment facing away from the interior of the tongue plate is lower than the first surface.

[0006] In an embodiment of the present application, a first notch is provided on the base. When water or particulate matter enters the electrical connector, the opposite connector is plugged into the electrical connector of the present application. During the insertion of the opposite connector into the electrical connector, the water or particulate matter in the electrical connector can be pushed into the first notch by the opposite connector, thereby reducing or removing the water or particulate matter on the tongue plate, thereby reducing corrosion of the signal terminal. Furthermore, due to the provision of the notch, water can expand into the first notch under the action of surface tension, thereby reducing the area of water in contact with the contact section of the signal terminal and reducing corrosion of the signal terminal provided on the tongue plate.

[0007] In some embodiments, the first terminal may be a power signal terminal, an auxiliary signal terminal, or a configuration signal terminal. When the electrical connector and the opposite connector are connected for signal transmission, a potential difference may be generated due to a short circuit caused by water or particulate impurities, leading to an electrochemical reaction. By arranging the first notch in the direction of extension of the first terminal, water or particulate impurities on the first terminal can enter the first notch as much as possible, thereby minimizing corrosion and electrochemical corrosion of the signal terminal. Furthermore, because the projection of the tongue plate on a plane perpendicular to the third surface is located between the third surface and the fourth surface, there is a height difference between the third surface and the first surface, and between the fourth surface and the second surface, forming a stepped structure at the connection between the tongue plate and the base. Water or impurities are more likely to accumulate at the stepped structure, making the end of the first contact segment closer to the base more susceptible to corrosion. Arranging the first notch in the direction of extension of the first terminal further prevents corrosion at the end of the first contact segment closer to the base.

[0008] In some embodiments, the first notch also includes a first side surface, the first side surface is connected between the first bottom surface and the third surface, the angle between the plane where the first side surface is located and the plane where the first surface is located is a first angle, the angle between the first bottom surface and the first surface is a second angle, and the angle of the first angle is smaller than the angle of the second angle.

[0009] The first angle formed between the plane of the first side surface and the plane of the first surface is smaller than the second angle formed between the first bottom surface and the first surface. In other words, the first bottom surface near the tongue plate is flatter than the first side surface, allowing water on the first surface to easily spread into the first notch, thereby reducing corrosion of the signal terminals on the first surface.

[0010] In some embodiments, the first bottom surface is coplanar with the first surface, and the angle between the plane of the first side surface and the plane of the first surface is an obtuse angle. In these embodiments, the first bottom surface is coplanar with the first surface, allowing water to more easily flow into the first notch, thereby reducing corrosion of the signal terminals located on the first surface.

[0011] In some embodiments, the angle formed between the first bottom surface and the first surface is a first obtuse angle, and the angle formed between the plane containing the first side surface and the plane containing the first surface is a second obtuse angle, wherein the first obtuse angle is greater than the second obtuse angle. In these embodiments, the first bottom surface near the tongue plate is flatter than the first side surface, allowing water to easily flow into the first notch. Furthermore, the obtuse angle formed between the first bottom surface and the first surface allows moisture or particulate impurities that enter the first notch to be more easily thrown out of the electrical connector through operations such as shaking, thereby facilitating the removal of moisture or particulate impurities within the electrical connector.

[0012] In some embodiments, the first bottom surface is further connected to the third surface, and the bottom surface is a flat surface or a curved surface. In these embodiments, the first bottom surface is directly connected to the first surface and the third surface, that is, the first bottom surface is a smooth surface, which is simpler to process than machining a first notch including the first bottom surface and the first side surface.

[0013] In some embodiments, the contact section of each of the first terminals extends to the base, so that when the electrical connector is plugged into its matching opposite connector, the spring clip of the opposite connector can contact the contact section at any position of the tongue plate of the embodiment of the present application, ensuring that the electrical connector can be electrically connected to the opposite connector.

[0014] In some embodiments, there is a gap between the contact segment and the base. In the embodiments of the present application, due to the gap between the contact segment of the signal terminal and the base, when water or particulate impurities accumulate at the connection point between the base and the tongue plate, the water will be located at the gap between the contact segment and the base plate. In other words, the water or particulate impurities will not come into contact with the contact segment of the signal terminal, thereby preventing the water or particulate impurities from accelerating corrosion of the signal terminal.

[0015] In some embodiments, the electrical connector further includes a second terminal, the second terminal including a second contact segment and a second connecting segment, the second contact segment is at least partially embedded in the tongue plate, and the second contact segment is at least partially exposed from the second surface;

[0016] The base is provided with a second notch, the second notch is located in the extension direction of the length of the second contact segment, the second notch includes a second bottom surface, and the second bottom surface is connected to the second surface;

[0017] The second connecting section is at least partially embedded in the base, and the second connecting section is not exposed on the second bottom surface. The second contact section is at least partially exposed on the second surface, which can be that the surface of the second contact section facing away from the inside of the tongue plate protrudes from the second surface, so that the first contact section is partially exposed on the second surface. Alternatively, the second contact section is at least partially exposed on the second surface, which can also be that the surface of the second contact section facing away from the inside of the tongue plate is flush with the second surface or slightly lower than the second surface, but the surface of the second contact section facing away from the inside of the tongue plate is exposed. In an embodiment of the present application, a second notch is provided on the substrate, and the second surface of the tongue plate is connected to the second bottom surface of the second notch, so that water or particulate impurities on the second surface can be pushed into the second notch through the opposite connector, or the water extends into the second notch under the action of surface tension, which can reduce the water or particulate impurities that come into contact with the contact section of the signal terminal embedded on the second surface, thereby reducing or avoiding corrosion of the signal terminal.

[0018] In some embodiments, the second terminal may be a power signal terminal, an auxiliary signal terminal, or a configuration signal terminal. When the electrical connector and the opposite connector are connected for signal transmission, a potential difference may be generated due to a short circuit caused by water or particulate matter, leading to an electrochemical reaction. By providing the second notch in the direction of extension of the second terminal, water or particulate matter on the second terminal can enter the second notch as much as possible, thereby minimizing corrosion and electrochemical corrosion of the signal terminal.

[0019] In some embodiments, the electrical connector further includes a third terminal and a third notch; the third terminal includes a third contact segment and a third connecting segment, the third contact segment is at least partially embedded in the tongue plate, and the third contact segment is at least partially exposed from the second surface; the third notch is provided on the base, the third notch is located in the extension direction of the third contact segment, the third notch includes a third bottom surface, and the third bottom surface is connected to the second surface; the third connecting segment is at least partially embedded in the base, and the third connecting segment is not exposed from the third bottom surface; the third notch is spaced apart from the second notch.

[0020] The second surface of the tongue plate is connected to the third bottom surface of the third notch, so that water or particulate impurities on the second surface can be pushed into the second notch or the third notch through the opposite connector, or the water extends into the second notch or the third notch under the action of surface tension, that is, the storage area for water or particulate impurities is increased, thereby further reducing the water or particulate impurities that come into contact with the contact section of the signal terminal embedded in the second surface, thereby reducing or avoiding corrosion of the signal terminal.

[0021] In some embodiments, the electrical connector further includes a fourth terminal and a fourth notch; the fourth terminal includes a fourth contact segment and a fourth connecting segment, the fourth contact segment is at least partially embedded in the tongue plate, and the fourth contact segment is at least partially exposed to the first surface; the fourth notch is provided on the base, the fourth notch is located in the extension direction of the fourth contact segment, the fourth notch includes a fourth bottom surface, and the fourth bottom surface is connected to the first surface; the fourth connecting segment is at least partially embedded in the base, and the fourth connecting segment is not exposed to the fourth bottom surface; the fourth notch is spaced apart from the first notch.

[0022] The first surface of the tongue plate is connected to the fourth bottom surface of the fourth notch, so that water or particulate impurities on the first surface can be pushed into the first notch or the fourth notch through the opposite connector, or the water extends into the first notch or the fourth notch under the action of surface tension, that is, the storage area for water or particulate impurities is increased, thereby further reducing the water or particulate impurities that come into contact with the contact section of the signal terminal embedded in the first surface, thereby reducing or avoiding corrosion of the signal terminal.

[0023] In some embodiments, the electrical connector further includes a reinforcing plate, which is at least partially embedded within the tongue plate and at least partially embedded within the base. Providing the reinforcing plate within the electrical connector enhances the strength of the tongue plate. Furthermore, the reinforcing plate is partially embedded within the tongue plate and partially embedded within the base, thereby enhancing the securement between the tongue plate and the base and preventing the tongue plate from breaking relative to the base due to repeated insertion and removal of the electrical connector from the mating connector.

[0024] In some embodiments, the reinforcement plate is a metal reinforcement plate, and the surface of the reinforcement plate is covered with an insulating layer to avoid short circuit problems between different signal terminals caused by contact between the reinforcement plate and the signal terminals, thereby ensuring the normal transmission of various signals of the electrical connector and avoiding electrochemical reactions and corrosion between the signal terminals due to short circuits between different signal terminals, thereby improving the service life of the electrical connector.

[0025] On the other hand, the present application provides an electronic device, which includes a housing, a working module housed in the housing, and the above-mentioned electrical connector; the housing is provided with an opening, the electrical connector is passed through the opening and is electrically connected to the working module. When the opposite connector is plugged into the electrical connector, it can be electrically connected to the working module in the electronic device, thereby charging the working module in the electronic device or transmitting signals between the working modules in the electronic device. In addition, since the electronic device of the embodiment of the present application includes the above-mentioned electrical connector, and since the signal terminals of the above-mentioned electrical connector are not easily corroded, the electronic device including the electrical connector can also have a longer service life and can be safer when used.

[0026] In some embodiments, the electronic device includes a mainboard, at least some of the working modules are disposed on the mainboard, and the electrical connector is electrically connected to the mainboard to achieve electrical connection between the electrical connector and the working modules. By electrically connecting the working modules and the electrical connector to the mainboard, electrical connections between the working modules and between the electrical connectors can be conveniently achieved via connecting wires on the mainboard, simplifying the structure within the electronic device.

[0041] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0042] The present application provides an electronic device, which may be a mobile phone, tablet, e-reader, wearable watch, electronic audio, or other electronic product. The electronic device includes an electrical connector to achieve electrical connection with other electronic devices or structures through the electrical connector to achieve communication between the electronic device and other devices or other functions.

[0043] See also Figure 1 , Figure 1The figure shows a schematic diagram of the structure of an electronic device 1000 according to an embodiment of the present application. The electronic device 1000 is a mobile phone. It is understandable that the electronic device 1000 may also be other types of electronic devices, and the present application does not impose any special restrictions on the specific form of the electronic device 1000. The electronic device 1000 may include an electrical connector 100, a housing 200, and working modules 300 such as a power module, a camera module, an audio module, and a display module. An opening 210 is provided on the housing 200, and the electrical connector 100 is passed through the opening 210 and electrically connected to each working module. Among them, the electrical connector 100 can be used as a charging interface, a headphone interface, a data transmission interface, etc. Other electronic devices or structures are plugged into the electrical connector 100 through a counterpart connector that matches the electrical connector 100, thereby realizing electrical connection between other electronic devices or structures and the electronic device 1000 of the present application. The electrical connector 100 is electrically connected to the working modules of the electronic device 1000 to provide power or data transmission to the working modules 300 of the electronic device 1000 through the electrical connector 100. For example, the charging connector of a charger is plugged into the electrical connector 100 to power the working modules 300 of the electronic device 1000. In this case, the electrical connector 100 serves as the charging interface of the electronic device 1000. Alternatively, other electronic devices are connected to the electrical connector 100 via a connecting cable to enable signal transmission between the electronic device 1000 and other external structures. In this case, the electrical connector 100 serves as the data transmission interface.

[0044] In some embodiments, the electronic device 1000 further includes a motherboard 400, which may be a circuit board. At least some of the working modules 300 are disposed on the motherboard 400. The working modules 300 are electrically connected via traces on the motherboard 400, thereby enabling communication between the working modules 300. In these embodiments, the electrical connector 100 is electrically connected to the motherboard 400, thereby enabling electrical connection between the electrical connector 100 and the working modules 300 via the motherboard 400.

[0045] It should be noted that Figure 1 The structures of the electrical connector 100, working module 300, mainboard 400 and their positions in the electronic device 1000 shown are for illustration only and do not limit the structures of the electrical connector 100, working module 300, mainboard 400 and their positions in the electronic device 1000.

[0046] See also Figure 2 and Figure 3 , Figure 2 Shown Figure 1 The schematic structural diagram of the electrical connector 100 of the electronic device 1000 is shown. Figure 3 Shown Figure 2The schematic cross-sectional view of the electrical connector 100 along the II direction is shown. In this embodiment, the electrical connector 100 is a Type-C interface connector. It is understandable that in some embodiments, the electrical connector 100 may also be a Type-A interface connector, a Type-B interface connector, etc. The electrical connector 100 includes a housing 10 and an electrical connector body 20. The housing 10 is a tubular structure, and the electrical connector body 20 is partially inserted into the housing 10 and fixed to the housing 10, that is, the housing 10 covers a portion of the surface of the electrical connector body 20 to protect the electrical connector 100.

[0047] The housing 10 is provided with a fixing end 11. When the electrical connector 100 is installed in the electronic device 1000, the housing 10 of the electrical connector 100 is fixed to the housing 200 of the electronic device 1000 or other structures of the electronic device 1000, thereby securing the electrical connector 100 to the electronic device 1000 via the fixing end 11. In this embodiment, the fixing ends 11 are fixing ears symmetrically arranged on opposite sides of the housing 10. The fixing ears are provided with fixing holes, through which screws are passed to secure the housing 10 to the housing 200 of the electronic device 1000. It is understood that in other embodiments, the fixing ends 11 can also be fixed to the electronic device 1000 by other means such as welding or bonding.

[0048] In some embodiments, the housing 10 may be made of a metal material and may function as an electromagnetic shield, thereby preventing other structures outside the electrical connector 100 from influencing signals transmitted in the electrical connector 100 .

[0049] See also Figure 4 , Figure 4 Shown Figure 2 The electrical connector body 20 of the electrical connector 100 is shown in FIG. The electrical connector body 20 includes an insulating body 21 and a plurality of signal terminals 22 provided on the insulating body 21. It should be noted that, Figure 4 In order to avoid being redundant in the drawings, only one signal terminal 22 is schematically indicated. Figure 4 The electrical connector 100 of the embodiment shown in the figure has multiple signal terminals 22, and the multiple signal terminals 22 are arranged in parallel. The insulating body 21 is made of insulating material and can support and protect the multiple signal terminals 22 arranged thereon. When the opposite connector is plugged into the electrical connector 100 of the embodiment of the present application, the opposite connector is electrically connected to the signal terminals 22 of the electrical connector 100 to achieve communication between the opposite connector and the electrical connector 100. Figure 6 , Figure 6 Shown Figure 2, which is a schematic diagram of the structure of the electrical connector 100 when plugged into the counterpart connector 500. The counterpart connector 500 includes a spring clip 510 for connecting to another electronic device or structure. When the counterpart connector 500 is plugged into the electrical connector 100 of the present application, the spring clip 510 of the counterpart connector 500 contacts the signal terminals 22 of the electrical connector 100 of the present application. The other electronic device or structure connected to the counterpart connector 500 then uses the signal terminals 22 of the electrical connector 100 to charge the electronic device 1000 and transmit signals.

[0050] Please refer again Figure 3 and Figure 4 , the insulating body 21 includes a tongue plate 211 and a base 212 connected to the tongue plate 211. The tongue plate 211 includes a first surface 2111 and a second surface 2112 that are opposite to each other. The base 212 includes a third surface 2121 and a fourth surface 2122 that are opposite to each other. In the present application, the position where the base 212 is connected to the tongue plate 211 forms a stepped structure. Specifically, the distance between the third surface 2121 and the fourth surface 2122 is greater than the distance between the first surface 2111 and the second surface 2112. That is, the thickness of the tongue plate 211 is less than the thickness of the base 212, wherein the thickness direction of the tongue plate 211 and the thickness direction of the base 212 are both Figure 4 In the Z direction shown in FIG. , in the plugging direction of the electrical connector 100 and the opposite connector 500, at least one orthographic projection of the tongue plate 211 on a plane perpendicular to the third surface 2121 is located between the third surface 2121 and the fourth surface 2122. For example, see Figure 4a , Figure 4a For tongue plate 211 Figure 4 Projection view on any plane A in . Among them, Figure 4a The middle area B is the orthographic projection of the tongue plate 211 on plane A, that is, the projection of the tongue plate 211 on plane A when the light shines from the X direction in the figure to the direction perpendicular to plane A. The X direction is the plugging and unplugging direction when the electrical connector 100 is plugged in and out of the opposite connector. It should be noted that plane A is a plane perpendicular to the third surface 2121. Plane A is not an actual plane on the electrical connector 100 in the embodiment of the present application. It is only a virtual plane introduced to explain in detail that "the orthographic projection of the tongue plate 211 on the plane perpendicular to the third surface 2121 is located between the third surface 2121 and the fourth surface 2122". A first limiting surface 2123a is connected between the third surface 2121 and the first surface 2111 (the specific position can be further referred to). Figure 10a), the third surface 2121, the first limiting surface 2123a, and the first surface 2111 are connected to form a stepped structure. In some embodiments, a second limiting surface 2123b is connected between the fourth surface 2122 and the second surface 2112, and the fourth surface 2122, the second limiting surface 2123b, and the second surface 2112 are connected to form a stepped structure. Specifically, in this embodiment, the third surface 2121 and the first surface 2111 are located on the same side of the electrical connector 100, and the fourth surface 2122 and the second surface 2112 are located on the other side of the electrical connector 100. In some embodiments, the first surface 2111 and the second surface 2112 are symmetrical relative to a reference plane, and the third surface 2121 and the fourth surface 2122 are also symmetrical relative to the reference plane. In this case, the thickness direction of the tongue plate 211 and the base 212 are both perpendicular to the reference plane. The reference plane refers to a plane located between the first surface 2111 and the second surface 2112 and intersecting with the limiting surface 2123. It should be noted that the reference plane is a virtual plane, not an actual plane. The distance between the third surface 2121 and the reference plane is greater than the distance between the first surface 2111 and the reference plane, and thus the first surface 2111, the third surface 2121, and the first limiting surface 2123a connecting the first surface 2111 and the third surface 2121 form a stepped structure. The distance between the fourth surface 2122 and the reference surface is greater than the distance between the second surface 2112 and the reference surface, and thus the fourth surface 2122, the second surface 2112, and the second limiting surface 2123b connecting the fourth surface 2122 and the second surface 2112 form a stepped structure. In this embodiment, the first surface 2111, the second surface 2112, the third surface 2121, and the fourth surface 2122 are all parallel surfaces, and the first limiting surface 2123a and the second limiting surface 2123b are coplanar and perpendicular to the first surface 2111. It is understandable that in some embodiments, the first limiting surface 2123a may not be coplanar with the second limiting surface 2123b, and the first limiting surface 2123a and the second limiting surface 2123b may also form an angle with the first surface 2111 but not perpendicular.

[0051] When the opposite connector is plugged into the electrical connector 100, the first limiting surface 2123a and the second limiting surface 2123b can limit the degree to which the opposite connector is inserted into the electrical connector 100, so that the opposite connector can be inserted into the appropriate position of the electrical connector 100, thereby ensuring that the spring clip of the opposite connector can always make good contact with the signal terminal 22 of the electrical connector 100 of the present application, ensuring that the opposite connector and the electrical connector 100 of the embodiment of the present application have a good electrical connection effect. For details, please refer to Figure 6The counterpart connector 500 includes a housing 520 and an abutment surface 530 disposed within the housing 520. The abutment surface 530 surrounds the housing 520 and faces the opening of the housing 520. When the counterpart connector 500 is plugged into the electrical connector 100, the tongue 211 of the electrical connector 100 is inserted into the counterpart connector 500 through the opening of the housing 520. The spring clip 510 of the counterpart connector 500 contacts the signal terminal 22 of the electrical connector 100 to achieve electrical connection between the counterpart connector 500 and the electrical connector 100. In some embodiments, when the counterpart connector 500 and the electrical connector 100 are properly plugged into each other, both the first limiting surface 2123a and the second limiting surface 2123b contact the abutting surface 530. Thus, the first limiting surface 2123a and the second limiting surface 2123b limit the insertion depth of the counterpart connector 500 relative to the electrical connector 100, ensuring that the spring member 510 of the counterpart connector 500 can always make good contact with the signal terminal 22 of the electrical connector 100 of the present application. In some embodiments, the edge where the first limiting surface 2123a connects to the third surface 2121 is chamfered, thereby forming a first connecting surface 2124 connecting the first limiting surface 2123a and the third surface 2121; and the edge where the second limiting surface 2123b connects to the fourth surface 2122 is chamfered, thereby forming a second connecting surface 2125 connecting the limiting surface 2123 and the fourth surface 2122. In some embodiments, the abutment surface 530 of the opposite connector 500 can be in contact with both the first limiting surface 2123a and the first connecting surface 2124, or the abutment surface 530 of the opposite connector 500 can be in contact with both the second limiting surface 2123b and the second connecting surface 2125, that is, the first limiting surface 2123a and the first connecting surface 2124 can jointly limit the insertion degree of the opposite connector 500 relative to the electrical connector 100, or the second limiting surface 2123b and the second connecting surface 2125 can jointly limit the insertion degree of the opposite connector 500 relative to the electrical connector 100.

[0052] In some embodiments of the present application, the tongue plate 211 and the base 212 may be an integral structure formed by an integral molding process, and the tongue plate may be formed by extending the base forward.

[0053] See also Figure 5 , Figure 5 Shown Figure 4The schematic diagram of the structure of the electrical connector body 20 after being cut along the II-II direction is shown. In the embodiment of the present application, the plurality of signal terminals 22 can be respectively arranged on the first surface 2111 side and the second surface 2112 side of the tongue plate 211. It can be understood that in some embodiments, the plurality of signal terminals 22 can be all arranged on the first surface 2111 side of the tongue plate 211 or all arranged on the second surface 2112 side of the tongue plate 211. In this embodiment, the signal terminal 22 arranged on the first surface 2111 side is a first-side signal terminal, and the signal terminal 22 arranged on the second surface 2112 side is a second-side signal terminal. There is a gap between adjacent signal terminals 22 arranged on the same surface side of the tongue plate 211 to avoid interference between the signals transmitted by the adjacent signal terminals 22. In this embodiment, the signal terminals 22 are arranged in parallel, and the extension direction of each signal terminal 22 is perpendicular to the direction of the limiting surface 2123, which is Figure 4 In some embodiments, the first side signal terminals on the first surface 2111 and the second side signal terminals on the second surface 2112 are symmetrically arranged to ensure the forward and reverse insertion function of the electrical connector 100. In this embodiment, there are twelve first side signal terminals and twelve second side signal terminals, and the first side signal terminals and the second side signal terminals are symmetrically arranged. It should be noted that the number of signal terminals 22 can vary according to actual product requirements and is not limited in this application.

[0054] Each signal terminal 22 includes a contact segment 22a and a connecting segment 22b connected between the contact segment 22a and the welding segment 22c. The contact segment 22a is embedded in the tongue plate 211, and the surface of the contact segment 22a facing away from the tongue plate 211 is exposed on the first surface 2111 or the second surface 2112 of the tongue plate 211. When the opposite connector is plugged into the electrical connector 100, the spring of the opposite connector contacts the contact segment 22a of the signal terminal 22 to achieve electrical connection between the opposite connector and the electrical connector 100. It should be noted that Figure 5 In the embodiment shown, only the specific positions of the contact sections 22a of the two signal terminals 22 are schematically indicated (eg Figure 5 To avoid clutter in the figure, the positions of the contact segments 22a of the other signal terminals 22 are not specifically indicated. In practice, each signal terminal 22 includes a contact segment 22a embedded in the tongue plate 211, with the surface of the contact segment 22a facing away from the tongue plate 211 exposed on either the first surface 2111 or the second surface 2112 of the tongue plate 211.

[0055] Specifically, the contact segment 22a of the first-side signal terminal is at least partially embedded in the tongue plate 211, and at least partially exposed from the first surface 2111. The contact segment 22a of the first-side signal terminal can be electrically connected to the opposite-end connector. The contact segment 22a of the first-side signal terminal being at least partially exposed from the first surface 2111 can mean that the surface of the first-side signal terminal's contact segment 211 facing away from the interior of the tongue plate 211 protrudes from the first surface 2111, thereby partially exposing the contact segment 211 of the first-side signal terminal. Alternatively, the contact segment 211 of the first-side signal terminal being at least partially exposed from the first surface 2111 can also mean that the surface of the first-side signal terminal's contact segment 211 facing away from the interior of the tongue plate 211 is flush with or slightly lower than the first surface 2111, but the surface of the first-side signal terminal's contact segment 211 facing away from the interior of the tongue plate is exposed. In other words, a strip groove can be recessed in the first surface 2111 of the tongue plate 211, with the contact section 211 of the first-side signal terminal embedded in the strip groove, and the surface of the contact section 211 of the first-side signal terminal facing away from the tongue plate 211 exposed. When the thickness of the contact section 211 of the first-side signal terminal is greater than the depth of the strip groove, the surface of the contact section 211 of the first-side signal terminal facing away from the interior of the tongue plate 211 protrudes above the first surface 2111; when the thickness of the contact section 211 of the first-side signal terminal is equal to the depth of the strip groove, the surface of the contact section 211 of the first-side signal terminal facing away from the interior of the tongue plate 211 is flush with the first surface 2111; and when the thickness of the contact section 211 of the first-side signal terminal is less than the depth of the strip groove, the surface of the contact section 211 of the first-side signal terminal facing away from the interior of the tongue plate 211 is lower than the first surface 2111.

[0056] The contact segment 22a of the second-side signal terminal is at least partially embedded in the second surface 2112 of the tongue plate 211 and at least partially exposed from the second surface 2112. The contact segment 22a of the second-side signal terminal can be electrically connected to the opposite-end connector. The contact segment 211 of the second-side signal terminal being at least partially exposed from the second surface 2112 can mean that the surface of the second-side signal terminal's contact segment 211 facing away from the interior of the tongue plate 211 protrudes from the second surface 2112, thereby partially exposing the contact segment 211 of the second-side signal terminal from the second surface 2112. Alternatively, the contact segment 211 of the second-side signal terminal being at least partially exposed from the second surface 2112 can also mean that the surface of the second-side signal terminal's contact segment 211 facing away from the interior of the tongue plate 211 is flush with or slightly lower than the second surface 2112, but the surface of the second-side signal terminal's contact segment 211 facing away from the interior of the tongue plate is exposed.

[0057] The connecting section 22b is embedded in the insulating body 21, and the welding section 22c connected to the connecting section 22b extends out of the insulating body 21 away from at least a portion of the connecting section 22b. The connecting section 22b being embedded in the insulating body 21 means that the connecting section 22b is located inside the insulating body 21 and is not exposed to the insulating body 21. Specifically, in the embodiment of the present application, the connecting section 22b is at least partially embedded in the base 212, that is, at least a portion of the connecting section 22b is located inside the base 212 and is not exposed to the base 212. In this embodiment, the end of the contact section 22a facing the base 212 extends to the base 212, and the connecting section 22b connected to the contact section 22a is completely embedded in the base 212 of the insulating body 21. In this embodiment, the portion of the connecting section 22b close to the contact section 22a can be collinear with the contact section 22a. The welding section 22c is used to electrically connect other structures inside the electronic device 1000. Because welding section 22c is connected to contact section 22a via connecting section 22b, when the spring element of the opposite connector contacts contact section 22a, the opposite connector can be electrically connected to other structures within electronic device 1000 electrically connected to welding section 22c, thereby electrically connecting electronic device 1000 to other electronic devices or structures via electrical connector 100. In this embodiment, welding section 22c is electrically connected to motherboard 400 of electronic device 1000 by welding or other means, thereby electrically connecting electrical connector 100 to motherboard 400 and the working modules disposed on motherboard 400.

[0058] When a small amount of water or particulate matter enters the electrical connector 100, due to the stepped structure on the insulating body 21, the water or particulate matter tends to accumulate at the locations of the stepped structure (i.e., where the first surface 2111 intersects the first limiting surface 2123a and where the second surface 2112 intersects the second limiting surface 2123b). This causes the portion of the contact segment 22a near the limiting surface 2123 to be in contact with the water or particulate matter for a prolonged period of time, resulting in increased corrosion of the portion of the contact segment 22a near the limiting surface 2123, and thus shortening the life of the electrical connector 100. Furthermore, in some embodiments, the water or particulate matter can cause short circuits between different signal terminals, leading to electrochemical reactions between the different signal terminals, thereby accelerating corrosion of the signal terminals. For example, in some embodiments, the multiple signal terminals 22 include power signal terminals, auxiliary signal terminals, or configuration signal terminals. Short circuits between the power signal terminal and the auxiliary signal terminal or the configuration signal terminal due to water or particulate matter can accelerate electrochemical reactions, thereby accelerating corrosion of the power signal terminal, the auxiliary signal terminal, or the configuration signal terminal.

[0059] In the embodiment of the present application, the base 212 is provided with at least one notch. The notch may include a first side notch and a second side notch. Both the first side notch and the second side notch include a bottom surface, with the bottom surface of the first side notch contiguous with the first surface, and the bottom surface of the second side notch contiguous with the second surface. In some embodiments, the first side notch may extend from the first limiting surface 2123a to the third surface 2121, and the second side notch may extend from the second limiting surface 2123b to the fourth surface 2122. In the embodiment of the present application, the base 212 may have only the first side notch or only the second side notch, or may have both the first and second side notches, and the number of first and second side notches may be one or more. In this embodiment, there are two first side notches, namely the first notch 2131 and the fourth notch 2133; there are also two second side notches, namely the second notch and the third notch. It is understood that the number of first and second side notches is not specifically limited in this application and can be determined based on actual needs. For example, in some embodiments, there may be only the first notch 2121 , or only the first notch 2121 and the second notch, or only the first notch 2121 and the third notch 2123 .

[0060] In this embodiment, the first notch 2131 and the second notch are symmetrically arranged on both sides of the base 212, and the fourth notch 2133 and the third notch are symmetrically arranged on both sides of the base 212. It is understood that, according to actual needs, the first notch 2131 and the second notch can be staggered on both sides of the base 212, and the fourth notch 2133 and the third notch can be staggered on both sides of the base 212.

[0061] The first notch 2131 includes a first bottom surface 2131a, and the fourth notch 2133 includes a fourth bottom surface 2133a. Both the first bottom surface 2131a and the fourth bottom surface 2133a are connected to the first surface 2111. The second notch includes a second bottom surface 2132a, and the third notch includes a third bottom surface. Both the second bottom surface 2132a and the third bottom surface are connected to the second surface 2112. In this embodiment, the first bottom surface 2131a is connected to the first surface 2111, the fourth bottom surface 2133a is connected to the first surface 2111, the second bottom surface 2132a is connected to the second surface 2112, and the third bottom surface is connected to the second surface 2112. When the opposite connector is plugged into the electrical connector 100, water or particulate matter on the first surface 2111 can be pushed by the opposite electrical connector onto the first bottom surface 2131a and the fourth bottom surface 2133a connected to the first surface 2111. Water or particulate matter on the second surface 2112 can be pushed by the opposite electrical connector onto the second bottom surface 2132a and the third bottom surface 2134a connected to the second surface 2112. Alternatively, water on the first surface 2111 can be stretched to the first bottom surface 2131a and the fourth bottom surface 2133a due to surface tension, and water on the second surface 2112 can be stretched to the second bottom surface 2132a and the third bottom surface due to surface tension. Since the connecting section 22 b of the signal terminal 22 is completely embedded in the base 212, that is, the connecting section 22 b of the signal terminal 22 does not expose the first bottom surface 2131 a, the fourth bottom surface 2133 a, the second bottom surface 2132 a, and the third bottom surface 2134 a. Therefore, impurities that enter the first bottom surface 2131 a, the fourth bottom surface 2133 a, the second bottom surface 2132 a, and the third bottom surface 2134 a will not come into contact with the signal terminal. This also reduces impurities on the first surface 2111 and the second surface 2112, thereby reducing or preventing corrosion of the signal terminal 22.

[0062] In the embodiment of the present application, the first bottom surface 2131a is also connected to the third surface 2121, that is, the first bottom surface 2131a is connected to the first surface 2111 and the third surface 2121. The fourth bottom surface 2133a is also connected to the third surface 2121, that is, the fourth bottom surface 2133a is connected to the first surface 2111 and the third surface 2121. The second bottom surface 2132a is also connected to the fourth surface 2122, that is, the second bottom surface 2132a is connected to the second surface 2112 and the fourth surface 2122; the third bottom surface is also connected to the fourth surface 2122, that is, the third bottom surface is connected to the second surface 2112 and the fourth surface 2122. In this embodiment, the first bottom surface 2131a and the fourth bottom surface 2133a, the second bottom surface 2132a and the third bottom surface are all flat or smooth curved surfaces. In the embodiment of the present application, by providing a first side notch or a second side notch on the base 212, or by providing a first side notch and a second side notch on the base 212. Furthermore, when the signal terminal 22 is located on the first surface 2111 side, a first side notch is provided on the base 212; when the signal terminal is located on the second surface 2112 side, a second side notch is provided on the base 212. When water or particulate matter enters the electrical connector 100, the electrical connector 100 of the present application is plugged into a counterpart connector. During the insertion of the counterpart connector into the electrical connector 100, the water or particulate matter within the electrical connector 100 can be pushed into the first or second side notch by the counterpart connector, thereby reducing or removing the water or particulate matter on the tongue plate 211 and, in turn, reducing corrosion of the signal terminal 22. Furthermore, due to the provision of the notch, water accumulated at the stepped structure of the insulating body 21 can expand into the notch due to surface tension, thereby reducing the area of water in contact with the contact segment 22a of the signal terminal 22 and reducing corrosion of the signal terminal 22 located on the tongue plate 211.

[0063] In some embodiments, adjacent first-side notches are spaced apart, and adjacent second-side notches are spaced apart, which can delay the corrosion of the signal terminal 22 while avoiding affecting the strength of the base 212 due to the setting of the notches, thereby avoiding breakage or other damage to the base 212 when the opposite connector and the electrical connector 100 are plugged in and out.

[0064] In this embodiment of the present application, the first side notch is located in the extension direction of at least one signal terminal 22 among the first-side signal terminals, i.e., the first side notch is directly opposite the at least one signal terminal 22. The second side notch is located in the extension direction of at least one signal terminal 22 among the second-side signal terminals, i.e., the second side notch is directly opposite the at least one signal terminal 22. The signal terminal directly opposite the notch may be a power signal terminal. Specifically, in this embodiment, the first-side signal terminals include a first terminal 221 and a fourth terminal 223. The first notch 2131 in the first side notch is located in the extension direction of the first terminal 221, and the fourth notch 2133 in the first side notch is located in the extension direction of the fourth terminal 223. The second-side signal terminals also include a second terminal and a fourth terminal. The second notch in the second side notch is located in the extension direction of the second terminal, and the third notch in the second side notch is located in the extension direction of the fourth terminal. The first terminal 221, the second terminal, the fourth terminal 223, and the fourth terminal may be signal terminals among the multiple signal terminals 22 of the electrical connector 100 that are susceptible to electrochemical corrosion. In other words, in the embodiment of the present application, the notches can be provided in the extension direction of the signal terminals 22 that are more susceptible to corrosion, thereby more effectively protecting the signal terminals 22 and preventing or reducing corrosion. Specifically, by providing notches in the extension direction of the first terminal 221, the fourth terminal 223, and the second and fourth terminals, moisture or impurities accumulated on the first terminal 221, the fourth terminal 223, and the second and fourth terminals can be pushed into the notches by the opposite connector, or extended into the notches due to surface tension, thereby reducing or preventing the occurrence of electrochemical reactions and further reducing or preventing corrosion of the signal terminals 22 caused by the ingress of water or particulate impurities into the electrical connector 100.

[0065] In this embodiment, the fifth and sixth signal terminals along the Y-axis direction of the first-side signal terminals are first terminals 221, the ninth and tenth signal terminals are fourth terminals, the first notch 2131 is provided in the extension direction of the fifth and sixth signal terminals of the first-side signal terminals, and the fourth notch 2133 is provided in the extension direction of the ninth and tenth signal terminals of the first-side signal terminals; the fifth and sixth signal terminals along the Y-axis direction of the second-side signal terminals are second terminals, and the ninth and tenth signal terminals are both third terminals.

[0066] The second notch is provided in the extending direction of the fifth and sixth signal terminals of the second side signal terminals, and the fourth notch is provided in the extending direction of the ninth and tenth signal terminals of the second side signal terminals.

[0067] In the embodiment of the present application, the plurality of signal terminals 22 may include various types of signal terminals 22 such as power signal terminals, configuration signal terminals, transmission signal terminals, ground signal terminals, auxiliary signal terminals, etc. Figure 7 , Figure 7 Shown in Figure 2Figure 1 shows the signal terminals of the electrical connector 100 of the illustrated embodiment. In this embodiment, the plurality of signal terminals 22 include four power signal terminals Vbus, configuration signal terminals CC1 / CC2, transmission signal terminals D+ / D- / Tx1+ / Tx1- / Rx1+ / Rx1- / Tx2+ / Tx2- / Rx2+ / Rx2-, a ground signal terminal GND, and auxiliary signal terminals SUB1 / SUB2. Among them, the power signal terminal Vbus is used to transmit the power signal; the configuration signal terminal CC1 / CC2 is used to confirm the forward and reverse insertion direction and the transmission direction during the connection process, as well as the USB PD BCM code signal transmission function to realize the functional configuration of the load; the transmission signal terminal D+ / D- / Tx1+ / Tx1- / Rx1+ / Rx1- / Tx2+ / Tx2- / Rx2+ / Rx2- is used for signal transmission; the ground signal terminal GND is grounded; the auxiliary signal terminal SUB1 / SUB2 plays different roles in different application scenarios. For example, when DP signal transmission is performed in ALT MODE mode, SUB1 / SUB2 serves as an audio transmission channel. When entering the TYPE-C analog audio headset accessory mode, it serves as a microphone signal transmission channel. In this embodiment, the first side signal terminals are, in sequence along the Y-axis direction, the ground signal terminal GND, the transmission signal terminal Tx1+, the transmission signal terminal Tx1-, the power signal terminal Vbus, the configuration signal terminal CC1, the transmission signal terminal D+, the transmission signal terminal D-, the auxiliary signal terminal SUB1, the power signal terminal Vbus, the transmission signal terminal Rx1-, the transmission signal terminal Rx1+, and the ground signal terminal GND, wherein the adjacent power signal terminal Vbus and the configuration signal terminal CC1 are the first terminal 221, and the adjacent auxiliary signal terminal SUB1 and the power signal terminal Vbus are the fourth Terminal 223; The signal terminals on the second side are, in order along the Y-axis direction, the ground signal terminal GND, the transmission signal terminal Rx1+, the transmission signal terminal Rx1-, the power signal terminal Vbus, the auxiliary signal terminal SUB2, the transmission signal terminal D-, the transmission signal terminal D+, the configuration signal terminal CC2, the power signal terminal Vbus, the transmission signal terminal Tx2-, the transmission signal terminal Tx2+, and the ground signal terminal GND. The adjacent power signal terminal Vbus and the configuration signal terminal CC2 are second terminals, and the adjacent auxiliary signal terminal SUB2 and the power signal terminal Vbus are third terminals. In this embodiment, the first notch 2131 is provided in the extending direction of the adjacent power signal terminal Vbus and the configuration signal terminal CC1, the fourth notch 2133 is provided in the extending direction of the adjacent power signal terminal Vbus and the auxiliary signal terminal SUB1, the second notch is provided in the extending direction of the power signal terminal Vbus and the configuration signal terminal CC2, and the third notch is provided in the extending direction of the power signal terminal Vbus and the auxiliary signal terminal SUB2.When water or particulate impurities enter the electrical connector 100, the water or particulate impurities can easily cause a short circuit between the power signal terminal Vbus and the configuration signal terminal CC1, and between the power signal terminal Vbus and the auxiliary signal terminal SUB1, which will accelerate the corrosion of the power signal terminal, the configuration signal terminal and the auxiliary signal terminal, and affect the normal operation of the electrical connector 100.

[0068] Please also refer to Figure 5 and Figure 8 , Figure 8 Shown Figure 5 An enlarged schematic diagram of position III on the electrical connector body 20 is shown. In some embodiments, the first notch 2131 may further include a first side surface 2131b connected between the first bottom surface 2131a and the third surface 2121. The first bottom surface 2131a is closer to the tongue plate 211 relative to the first side surface 2131b. The first side surface 2131b is more inclined than the first bottom surface 2131a relative to the plane of the first surface 2111. That is, a first angle α1 formed between the first side surface 2131b and the plane of the first surface 2111 is smaller than a second angle α2 formed between the first bottom surface 2131a and the plane of the first surface 2111. In other words, the first bottom surface 2131a near the tongue plate 211 is flatter than the first side surface 2131b, allowing moisture to easily spread into the first notch 2131, thereby reducing corrosion of the signal terminals 21 located on the first surface 2111 side. Similarly, in some embodiments, the fourth notch 2133 also includes a third side surface 2133b connected between the fourth bottom surface 2133a and the third surface 2121. The third side surface 2133b is more inclined than the fourth bottom surface 2133a relative to the plane of the first surface 2111. That is, the fourth bottom surface 2133a near the tongue plate 211 is flatter than the third side surface 2133b, allowing moisture to easily spread into the fourth notch 2133. In this embodiment, the first angle α1 and the second angle α2 are both obtuse angles. In some embodiments, the second notch also includes a second side surface 2132b connected between the second bottom surface 2132a and the fourth surface 2122. The second side surface 2132b is more inclined than the second bottom surface 2132a relative to the plane of the second surface 2112. In other words, the second bottom surface 2132a near the tongue plate 211 is flatter than the second side surface 2132b, allowing moisture to easily spread into the second notch. In some embodiments, the third notch also includes a fourth side surface connected between the third bottom surface and the fourth surface 2122. The fourth side surface is more inclined than the third bottom surface relative to the plane of the second surface 2112. In other words, the third bottom surface near the tongue plate 211 is flatter than the fourth side surface, allowing moisture to easily spread into the third notch.

[0069] Please refer again Figure 4 In this embodiment of the present application, the electrical connector 100 further includes a reinforcing plate 30 embedded within the insulating body 21. The reinforcing plate 30 is stronger than the insulating body 21, thereby enhancing the strength of the insulating body 21. Specifically, the reinforcing plate 30 is at least partially embedded within the tongue plate 211 and at least partially embedded within the base 212, thereby enhancing the fixing effect between the tongue plate 211 and the base 212 and preventing the tongue plate 211 from breaking relative to the base 212 due to repeated insertion and removal of the electrical connector 100 from the opposite connector.

[0070] In some embodiments, the reinforcing plate 30 is a metal plate. The surface of the reinforcing plate 30 is covered with an insulating material to prevent short circuits between the signal terminals 22 caused by contact between the reinforcing plate 30 and the signal terminals 22. This ensures the normal transmission of various signals in the electrical connector 100 and prevents electrochemical reactions and corrosion between the signal terminals 22 caused by short circuits between the signal terminals 22, thereby extending the service life of the electrical connector 100.

[0071] See also Figure 9 , Figure 9 The electrical connector 100 according to another embodiment of the present application is shown. Figure 4 Schematic diagram of the structure after being cut along the II-II direction. Figure 9 The electrical connector 100 of the embodiment shown is Figure 4The electrical connector 100 of the illustrated embodiment differs in that the first bottom surface 2131a of the first notch 2131 is coplanar with the first surface 2111, and the fourth bottom surface 2133a of the fourth notch 2133 is coplanar with the first surface 2111. In this embodiment, the first bottom surface 2131a is coplanar with the first surface 2111, meaning that the second angle between the first bottom surface 2131a and the first surface 2111 is 180°. The angle between the plane containing the first side surface 2131b and the plane containing the first surface 2111 is a first angle, which is an obtuse angle. The connecting sections 22b of at least some of the first-side signal terminals 22 include a bent section 2231. In this embodiment, both the first terminal 221 and the fourth terminal 223 are first-side signal terminals. The connecting section 22b of the first terminal 221 is a first connecting section, and the connecting section 22b of the fourth terminal is a fourth connecting section. In the embodiment of the present application, at least the first connecting section of the first terminal 221 and the fourth connecting section of the fourth terminal of the first-side signal terminals include a bent section 2231. Alternatively, all of the connecting sections 22b of the first-side signal terminals may include a bent section 2231. The bent section 2231 is connected to the contact section 22a and bends toward the interior of the insulating body 22 relative to the contact section 22a. This prevents the connecting section 22b of the first-side signal terminal from being exposed to the first bottom surface 2131a or the fourth bottom surface 2133a. When impurities such as water or particles enter the first notch 2131 or the fourth notch 2133, the water or particles will not corrode the signal terminals.

[0072] Since the first notch 2131 is located in the extending direction of the first terminal 221 , the fourth notch 2133 is located in the extending direction of the fourth terminal 223 . The first-side signal terminal includes a first terminal 221 and a fourth terminal 223. Therefore, the first terminal 221 and the fourth terminal 223 include a bending section 2231, and the bending section 2231 is bent toward the interior of the insulating body 21 relative to the contact section 22a, which can ensure that when the first bottom surface 2131a and the fourth bottom surface 2133a are coplanar with the first surface 2111, the bending section 2231 can be embedded in the base 212, that is, the bending section 2231 of the first terminal 221 is located on the side of the first bottom surface 2131a facing the fourth surface 2122, and the connecting section 22b of the first terminal 221 will not be exposed from the first bottom surface 2131a; the bending section 2231 of the fourth terminal 223 is located on the side of the fourth bottom surface 2133a facing the fourth surface 2122, and the connecting section 22b of the fourth terminal 223 will not be exposed from the fourth bottom surface 2133a. When moisture enters the electrical connector 100, because the first bottom surface 2131a and the fourth bottom surface 2133a are coplanar with the first surface 2111, the moisture can more easily spread into the first bottom surface 2131a and the fourth bottom surface 2133a, thereby reducing contact between the contact segments 22a of the signal terminals 22 and the moisture, thereby alleviating corrosion of the signal terminals 22. Furthermore, because the bent sections 2231 bend toward the second surface 2112 and are embedded within the base 212, the insulating material covering the bent sections 2231 isolates the moisture from the signal terminals 22, thereby preventing moisture from contacting the connecting segments 22b of the signal terminals 22 and causing corrosion of the signal terminals 22.

[0073] In some embodiments, the second bottom surface 2132a of the second notch and the third bottom surface of the third notch are coplanar with the second surface 2112, and the connecting segments 22b of at least some of the second-side signal terminals include a bent section 2232. In the embodiment of the present application, the second and third terminals are both second-side signal terminals. The connecting segment 22b of the second terminal is the second connecting segment, and the connecting segment 22b of the third terminal is the third connecting segment. Only the second and third connecting segments may include the bent section 2232, or all of the connecting segments 22b of the second-side signal terminals may include the bent section 2232. The bent section 2232 is connected to the contact segment 22a, and the bent section 2231 bends relative to the contact segment 22a toward the first surface 2111. Because the bent section 2231 bends toward the first surface 2111 relative to the contact section 22a, the bent section 2232 can be embedded within the base 212 when the second bottom surface 2132a and the third bottom surface 2134a are coplanar with the second surface 2112. Specifically, the bent section 2232 of the second terminal is located on the side of the second bottom surface 2132a facing the third surface 2121, and the connecting section 22b of the second terminal does not expose the second bottom surface 2132a. The bent section 2232 of the third terminal is located on the side of the third bottom surface 2134a facing the third surface 2121, and the connecting section 22b of the third terminal does not expose the third bottom surface 2134a. When moisture enters the electrical connector 100, because the second bottom surface 2132a and the third bottom surface 2134a are coplanar with the second surface 2112, the moisture can more easily spread into the third area 2132a. Furthermore, since the bending section 2232 is bent toward the third surface 2121 and embedded in the base 212, that is, the bending section 2232 will not expose the second bottom surface 2132a and the third bottom surface 2134a, moisture can be isolated from the signal terminal 22 by the insulating material covering the bending section 2232, thereby preventing moisture from contacting the signal terminal 22 and causing corrosion of the signal terminal 22.

[0074] See also Figure 10 and Figure 10a 、 Figure 10b , Figure 10 The electrical connector of another embodiment of the present application is shown along Figure 4 Schematic diagram of the structure after cutting along the II-II direction, Figure 10a for Figure 10 A magnified schematic diagram of the IV position in the middle, Figure 10b for Figure 10 side view. Figure 10 The embodiment shown is Figure 4The difference between the illustrated embodiment and the illustrated embodiment is that there is a distance between the contact segment 22a of at least one of the multiple signal terminals 22 and the base 212. In the embodiment of the present application, because there is a distance L between the contact segment 22a of the signal terminal 22 and the plane where the first limiting surface 2123a is located, when moisture accumulates at the location of the stepped structure, the moisture will be located at the distance L between the contact segment 22a and the plane where the first limiting surface 2123a is located. In other words, the moisture will not come into contact with the contact segment 22a of the signal terminal 22, thereby preventing moisture from entering the electrical connector 100 and accelerating corrosion of the signal terminal 22.

[0075] In this embodiment, the contact sections 22a of the first terminal 221, the second terminal, the fourth terminal 223, and the third terminal are spaced apart from the limiting surface 2123, thereby reducing contact between the first terminal 221, the fourth terminal 223, the second terminal, and the third terminal with moisture or particulate matter. Since, in this embodiment, the first terminal 221, the fourth terminal 223, the second terminal, and the third terminal are all signal terminals that are susceptible to electrochemical corrosion, by reducing contact between the first terminal 221, the fourth terminal 223, the second terminal, and the third terminal and moisture or particulate matter, corrosion of the signal terminals 22 within the electrical connector 100 can be reduced.

[0076] In some embodiments, the connection section 22b of the signal terminal 22, spaced apart from the plane where the contact section 22a and the first limiting surface 2123a are located, includes a bent section 2233. The bent section 2233 bends toward the interior of the insulating body 21 relative to the contact section 22a, thereby ensuring that the bent section 2233 is embedded within the insulating body 21. Specifically, the bent section 2233 does not protrude from the insulating body 21. The bent section 2233 is covered with an insulating material. In this embodiment, the bent section 2233 is partially embedded within the tongue plate 211 and partially embedded within the base 212. The portion of the bent section 2233 embedded within the tongue plate 211 corresponds to the distance between the contact section 22a and the plane where the first limiting surface 2123a is located. When moisture enters the electrical connector 100, the moisture is located at the distance between the contact section 22a and the plane where the first limiting surface 2123a is located. The moisture can be separated by the insulating material covering the bending section 2233, thereby preventing the moisture from corroding the signal terminals 22 and preventing the moisture from short-circuiting adjacent signal terminals 22 and accelerating the corrosion of the signal terminals 22.

[0077] In the present application, by forming a notch in the base 212, when water or some particulate impurities are present in the electrical connector 100, when the opposite connector is plugged into the electrical connector 100 of the present application, the water or particulate impurities in the electrical connector 100 can be pushed into the notch during the insertion of the opposite connector into the electrical connector 100, thereby reducing the amount of water or impurities on the signal terminals 22, thereby reducing or preventing corrosion of the signal terminals 22. Furthermore, when the amount of water entering the electrical connector 100 is small, the water film formed by the small amount of water in the electrical connector 100 can extend into the notch due to surface tension, thereby reducing the area of the water film in contact with the contact segment 22a of the signal terminal 22, thereby reducing corrosion at the signal terminal 22.

[0078] The above is a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications are also considered to be within the scope of protection of the present application.
