The first contact section is at least partially exposed out of the first surface, so that the surface of the first contact section, which is away from the tongue plate, protrudes out of the first surface, and the first contact section is partially exposed out of the first surface. Alternatively, the first contact section may be at least partially exposed from the first surface, or a surface of the first contact section facing away from the interior of the flap may be flush with the first surface or slightly lower than the first surface, but a surface of the first contact section facing away from the interior of the flap is exposed. In other words, a strip-shaped groove can be concavely arranged on the first surface of the tongue plate, the first contact section is embedded in the strip-shaped groove, and the surface of the first contact section, which is far away from the tongue plate, is exposed. When the thickness of the first contact section is higher than the depth of the strip-shaped groove, the surface of the first contact section departing from the inner part of the tongue plate protrudes out of the first surface; when the thickness of the first contact section is equal to the depth of the strip-shaped groove, the surface of the first contact section, which is far away from the inner part of the tongue plate, is flush with the first surface; when the thickness of the first contact section is lower than the depth of the strip-shaped groove, the surface of the first contact section, which faces away from the inner part of the tongue plate, is lower than the first surface.

In the embodiment of the application, the first notch is arranged on the base. When intaking in the electric connector or getting into some granule impurity, will peg graft the end connector with the electric connector of this application, to the in-process of end connector insert electric connector, water or granule impurity in the electric connector can be pushed into first breach to the end connector to reduce or get rid of water or granule impurity on the hyoplastron, and then can alleviate the corruption of signal terminal. And because the notch is arranged, water can extend into the first notch under the action of surface tension, so that the area of the water contacting with the contact section of the signal terminal is reduced, and the corrosion of the signal terminal arranged on the tongue plate is reduced.

In some embodiments, the first terminal may be a power signal terminal, an auxiliary signal terminal, or a configuration signal terminal, which may generate an electric potential difference due to a short circuit of water or particulate impurities to generate an electrochemical reaction when the electrical connector is communicated with the opposite-end connector for signal transmission. The first notch is arranged in the extending direction of the first terminal, so that water or particle impurities on the first terminal can enter the first notch as much as possible, and corrosion and electrochemical corrosion of the signal terminal are reduced as much as possible. And the projection of the tongue plate on the plane perpendicular to the third surface is positioned between the third surface and the fourth surface, so that a height difference exists between the third surface and the first surface, a height difference exists between the fourth surface and the second surface, and a step-shaped structure is formed at the connecting position of the tongue plate and the base. Moisture or impurities are more easily accumulated at the position of the stepped structure, so that the end, close to the base, of the first contact section is more easily corroded.

In some embodiments, the first bottom surface is coplanar with the first surface, and an included angle between a plane of the first side surface and a plane of the first surface is an obtuse angle.

In some embodiments, an included angle formed between the first bottom surface and the first surface is a first obtuse angle, an included angle formed between a plane where the first side surface is located and a plane where the first surface is located is a second obtuse angle, and an angle of the first obtuse angle is greater than that of the second obtuse angle. In these embodiments, the first bottom surface near the tongue plate is more gentle than the first side surface, and water can easily extend into the first notch. And the first bottom surface and the first surface form an obtuse angle, so that moisture or particle impurities entering the first gap can be more easily thrown out of the electric connector through operations such as throwing, and the moisture or particle impurities in the electric connector can be conveniently removed.

In this embodiment, the first surface 2111, the second surface 2112, the third surface 2121 and the fourth surface 2122 are parallel to each other, and the first stopper surface 2123a and the second stopper surface 2123b are coplanar and perpendicular to the first surface 2111.

In the embodiment of the present application, the plurality of signal terminals 22 may be disposed on the first surface 2111 side and the second surface 2112 side of the tongue plate 211. It is understood that, in some embodiments, the plurality of signal terminals 22 may be disposed on the first surface 2111 side of the tongue plate 211 or disposed on the second surface 2112 side of the tongue plate 211. In this embodiment, the signal terminal 22 provided on the first surface 2111 side is a first-side signal terminal, and the signal terminal 22 provided on the second surface 2112 side is a second-side signal terminal. A gap is formed between adjacent signal terminals 22 arranged on the same surface side of the tongue plate 211, so that interference between signals transmitted by the adjacent signal terminals 22 is avoided. In this embodiment, the signal terminals 22 are arranged in parallel, and the extending direction of each signal terminal 22 is a direction perpendicular to the limiting surface 2123, which is the X direction shown in fig. 4. In some embodiments, the first side signal terminals disposed on the first surface 2111 and the second side signal terminals disposed on the second surface 2112 are symmetrically disposed to satisfy the function of forward and backward insertion of the electrical connector 100. In this embodiment, the number of the first side signal terminals and the number of the second side signal terminals are twelve, and the first side signal terminals and the second side signal terminals are symmetrically arranged. It should be noted that the number of the signal terminals 22 may vary according to the requirements of the actual product, and the application is not limited thereto.

Each signal terminal 22 includes a contact section 22a and a connection section 22b connected between the contact section 22a and the soldering section 22 c. The contact section 22a is embedded in the tongue plate 211, and a surface of the contact section 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 end connector is plugged into the electrical connector 100, the spring plate of the opposite end connector contacts the contact section 22a of the signal terminal 22, so as to electrically connect the opposite end connector with the electrical connector 100. It should be noted that the specific positions of the contact sections 22a of two signal terminals 22 (as indicated by the leads 22a in fig. 5) are only schematically indicated in the embodiment shown in fig. 5, and the positions of the contact sections 22a of other signal terminals 22 are not specifically indicated in order to avoid the drawing redundancy. In practice, each signal terminal 22 includes a contact section 22a, the contact section 22a is embedded on the tongue plate 211, and a surface of the contact section 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.

Specifically, the contact section 22a of the first side signal terminal is at least partially embedded in the tongue plate 211, the contact section 22a of the first side signal terminal is at least partially exposed out of the first surface 2111, and the contact section 22a of the first side signal terminal can be electrically connected to the opposite end connector. The contact end 211 of the first side signal terminal is at least partially exposed out of the first surface 2111, and the method may include: the surface of the contact section 211 of the first side signal terminal facing away from the interior of the tongue 211 protrudes above the first surface 2111, such that the contact section 211 of the first side signal terminal is partially exposed at the first surface. Alternatively, the contact section 211 of the first side signal terminal at least partially exposed to the first surface 2111 may also be: 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 or slightly lower than the first surface 2111, but the surface of the contact section 211 of the first-side signal terminal facing away from the interior of the tongue plate is exposed. In other words, a strip-shaped groove may be recessed in the first surface 2111 of the tongue plate 211, the contact section 211 of the first-side signal terminal is embedded in the strip-shaped groove, and the surface of the contact section 211 of the first-side signal terminal, which is away from the tongue plate 211, is exposed. When the thickness of the contact section 211 of the first-side signal terminal is greater than the depth of the strip-shaped groove, the surface of the contact section 211 of the first-side signal terminal, which is away from the inside of the tongue plate 211, protrudes from 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-shaped groove, the surface of the contact section 211 of the first-side signal terminal, which is away from the inside of the tongue plate 211, is flush with the first surface 2111; when the thickness of the contact section 211 of the first-side signal terminal is lower than the depth of the strip-shaped groove, the surface of the contact section 211 of the first-side signal terminal facing away from the inside of the tongue plate 211 is lower than the first surface 2111.

The contact section 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, and the contact section 22a of the second side signal terminal can be electrically connected to the opposite terminal connector. The contact end 211 of the second side signal terminal is at least partially exposed out of the second surface 2112, which may be: the surface of the contact section 211 of the second side signal terminal facing away from the interior of the tongue 211 protrudes above the second surface 2112, such that the contact section 211 of the second side signal terminal is partially exposed at the second surface 2112. Alternatively, the contact section 211 of the second side signal terminal at least partially exposed to the second surface 2112 may also be: the surface of the contact section 211 of the second side signal terminal facing away from the interior of the tongue plate 211 is flush with the second surface 2112 or slightly lower than said second surface 2112, but the surface of the contact section 211 of the second side signal terminal facing away from the interior of the tongue plate is exposed.

The connecting section 22b is embedded in the insulating body 21, and a 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 22 b. The connection segment 22b is embedded in the insulating main body 21, which means that the connection segment 22b is located inside the insulating main body 21 and does not expose the insulating main body 21. Specifically, in the embodiment of the present application, the connecting segment 22b is at least partially embedded in the base 212, i.e., at least a portion of the connecting segment 22b is located in the base 212 and does not expose the base 212. In this embodiment, the end of the contact segment 22a facing the base 212 extends to the base 212, and the connecting segment 22b connected to the contact segment 22a is embedded in the base 212 of the insulating body 21. In this embodiment, a portion of the connecting section 22b near the contact section 22a may be collinear with the contact section 22 a. The solder segments 22c are used to electrically connect other structures within the electronic device 1000. Since the soldering segment 22c is connected to the contact segment 22a through the connecting segment 22b, when the spring of the opposite terminal connector contacts the contact segment 22a, the opposite terminal connector can be electrically connected to other structures in the electronic device 1000 electrically connected to the soldering segment 22c, so as to electrically connect the electronic device 1000 to other electronic devices or structures through the electrical connector 100. In this embodiment, the soldering section 22c is electrically connected to the main board 400 of the electronic device 1000 by soldering or the like, so that the electrical connector 100 is electrically connected to the main board 400 and the working module disposed on the main board 400.

When a small amount of water or particle impurities enter the electrical connector 100, because of the stepped structure on the insulating main body 21, water or particle impurities are easily gathered at the position of the stepped structure (i.e., the position where the first surface 2111 intersects with the first stopper face 2123a and the position where the second surface 2112 intersects with the second stopper face 2123 b), and a section of the contact section 22a close to the stopper face 2123 is in contact with the water or particle impurities for a long time, so that a section of the contact section 22a close to the stopper face 2123 is more easily corroded, and the service life of the electrical connector 100 is reduced. Also, in some embodiments, water or particulate impurities may short-circuit different signal terminals, causing electrochemical reactions between the different signal terminals, thereby accelerating corrosion of the signal terminals. For example, in some embodiments, the signal terminals 22 include power signal terminals, auxiliary signal terminals or configuration signal terminals, and after short-circuiting between the power signal terminals and the auxiliary signal terminals or configuration signal terminals due to water or particle impurities, the electrochemical reaction may be accelerated, so as to accelerate corrosion of the power signal terminals, the auxiliary signal terminals or the configuration signal terminals.

In the embodiment of the present application, at least one notch is formed on the base 212. The notch may include a first side notch and a second side notch. The first side notch and the second side notch comprise bottom surfaces, the bottom surface of the first side notch can be connected with the first surface, and the bottom surface of the second side notch can be connected with the second surface. In some embodiments, the first side indentation can be formed from the first stop surface 2123a to the third surface 2121, and the second side indentation can be formed from the second stop 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 the base may have the first notch and the second side notch, and the number of the first side notch and the second side notch may be one or more. In this embodiment, there are two first side notches, namely a first notch 2131 and a fourth notch 2133; the second side gap also has two, is second breach and third breach respectively. It is understood that the number of the first side notches or the second side notches is not particularly limited in the present application, and may be determined according to 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.

In this embodiment, the first notch 2131 and the second notch are symmetrically disposed on two sides of the base 212, and the fourth notch 2133 and the third notch are symmetrically disposed on two sides of the base 212. It can be understood that, according to actual needs, the first notch 2131 and the second notch are disposed on two sides of the base 212 and may be disposed in a staggered manner, and the fourth notch 2133 and the third notch are disposed on two sides of the base 212 and may be disposed in a staggered manner.

The first cutout 2131 includes a first bottom surface 2131a, the fourth cutout 2133 includes a fourth bottom surface 2133a, and both the first bottom surface 2131a and the fourth bottom surface 2133a are connected to the first surface 2111. The second notch comprises a second bottom surface 2132a, the third notch comprises a third bottom surface, and the second bottom surface 2132a and the third bottom surface are both connected with the second surface 2112. In this embodiment, the first bottom surface 2131a is connected to the first surface 2111, and the fourth bottom surface 2133a is connected to the first surface 2111; the second bottom surface 2132a is connected to the second surface 2112; the third bottom surface is connected to the second surface 2112. When the opposite-end connector is plugged into the electrical connector 100, water or particulate impurities on the first surface 2111 can be pushed into the first bottom surface 2131a connected with the first surface 2111 and the fourth bottom surface 2133a connected with the first surface 2111 by the opposite-end electrical connector, and water or particulate impurities on the second surface 2112 can be pushed into the second bottom surface 2132a connected with the second surface 2112 and the third bottom surface 2134a connected with the second surface 2112 by the opposite-end electrical connector. Alternatively, water on the first surface 2111 can be spread to the first bottom surface 2131a and the fourth bottom surface 2133a by the action of surface tension, and water on the second surface 2112 can be spread to the second bottom surface 2132a and the third bottom surface by the action of surface tension. Since the connecting portions 22b of the signal terminals 22 are all fitted in the base 212, that is, the connecting portions 22b of the signal terminals 22 are not exposed from the first bottom surface 2131a, the fourth bottom surface 2133a, the second bottom surface 2132a, and the third bottom surface 2134a, impurities entering the first bottom surface 2131a, the fourth bottom surface 2133a, the second bottom surface 2132a, and the third bottom surface 2134a do not contact with the signal terminals, and impurities on the first surface 2111 and the second surface 2112 can be reduced, thereby reducing or avoiding corrosion of the signal terminals 22.

In the embodiment of the present application, the first bottom surface 2131a is further connected to a 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 further connected to the third surface 2121, i.e., the fourth bottom surface 2133a is connected to both the first surface 2111 and the third surface 2121. The second bottom surface 2132a is further connected with a fourth surface 2122, i.e. the second bottom surface 2132a is connected with the second surface 2112 and the fourth surface 2122; the third bottom surface is also connected to fourth surface 2122, i.e., the third bottom surface is connected to second surface 2112 and fourth surface 2122. In this embodiment, the first bottom surface 2131a, the fourth bottom surface 2133a, the second bottom surface 2132a and the third bottom surface are all flat surfaces or smooth arc surfaces. In the embodiment of the present application, the first side notch or the second side notch is formed on the base 212, or the first side notch and the second side notch are formed on the base 212. When the signal terminal 22 is located on the first surface 2111 side, the base 212 is provided with a first side notch; when the signal terminals are located on the second surface 2112 side, the base 212 is provided with second side notches. When water enters the electric connector 100 or particles enter the electric connector 100, the end connector is plugged with the electric connector 100, and when the end connector is inserted into the electric connector 100, the water or particles in the electric connector 100 can be pushed into the first side notch or the second side notch by the end connector, so that the water or particles on the tongue plate 211 can be reduced or removed, and the corrosion of the signal terminal 22 can be reduced. Furthermore, since the notch is provided, the water accumulated at the step-like structure position of the insulating main body 21 can be spread into the notch by the surface tension, thereby reducing the area of the water in contact with the contact section 22a of the signal terminal 22 and reducing the corrosion of the signal terminal 22 provided on the tongue plate 211.

In some embodiments, the adjacent first side notches are arranged at intervals, and the adjacent second side notches are arranged at intervals, so that the strength of the base 212 is prevented from being affected due to the arrangement of the notches while the effect of delaying the corrosion of the signal terminal 22 is achieved, and therefore, the base 212 is prevented from being damaged by breakage and the like when the end connector is plugged into or unplugged from the electrical connector 100.

Specifically, in this embodiment, the first side signal terminal includes a first terminal 221 and a fourth terminal 223, a first notch 2131 of the first side notches is located in the extending direction of the first terminal 221, and a fourth notch 2133 of the first side notches is located in the extending direction of the fourth terminal 223; the second side signal terminal also comprises a second terminal and a fourth terminal, wherein a second gap in the second side gaps is positioned in the extending direction of the second terminal, and a third gap in the second side gaps is positioned in the extending direction of the fourth terminal. The first terminal 221, the second terminal, the fourth terminal 223, and the fourth terminal may be signal terminals that are susceptible to corrosion due to electrochemical reaction among the plurality of signal terminals 22 of the electrical connector 100. In other words, in the embodiment of the present application, the notch may be disposed in the extending direction of the signal terminal 22, which is relatively easy to corrode, in the signal terminal 22, so as to protect the signal terminal 22 more effectively and avoid or reduce corrosion. Specifically, the first terminal 221, the fourth terminal 223, the second terminal and the fourth terminal are provided with notches in the extending direction, and the moisture or impurities accumulated on the first terminal 221, the fourth terminal 223, the second terminal and the fourth terminal can be pushed into the notches by the butt end connector or extend into the notches under the action of surface tension, so that the generation of electrochemical reaction can be reduced or prevented, and the corrosion of the signal terminal 22 caused by water entering or particle impurities entering the electric connector 100 can be further reduced or prevented.

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

In the embodiment of the present application, the plurality of signal terminals 22 may include various types of signal terminals 22 such as a power signal terminal, a configuration signal terminal, a transmission signal terminal, a ground signal terminal, and an auxiliary signal terminal. Referring to fig. 7, fig. 7 is a signal terminal diagram of the electrical connector 100 of the embodiment shown in fig. 2. In the present 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/SUB 2. The power signal terminal Vbus is used for transmitting a power signal; the configuration signal terminal CC1/CC2 is used for confirming the positive and negative insertion direction and the transmission direction in the connection process, and the transmission function of a USB PD BCM code signal, and realizes the functional configuration of the load; the transmission signal terminals D +/D-/Tx1+/Tx1-/Rx1+/Rx1-/Tx2+/Tx2-/Rx2+/Rx2 are used for signal transmission; the grounding signal terminal GND is grounded; the auxiliary signal terminals SUB1/SUB2 may function differently in different application scenarios, for example, when DP signal transmission is performed in ALT MODE, SUB1/SUB2 may function as an audio transmission channel, and when TYPE-C analog audio headset accessory MODE is entered, as a microphone signal transmission channel. In this embodiment, the first side signal terminal is, in order along the Y-axis direction, a ground signal terminal GND, a transmission signal terminal Tx1+, a transmission signal terminal Tx1-, a power signal terminal Vbus, a configuration signal terminal CC1, a transmission signal terminal D +, a transmission signal terminal D-, an auxiliary signal terminal SUB1, a power signal terminal Vbus, a transmission signal terminal Rx1-, a transmission signal terminal Rx1+, and a ground signal terminal GND, wherein the adjacent power signal terminal Vbus and configuration signal terminal CC1 are the first terminal 221, and the adjacent auxiliary signal terminal 1 and power signal terminal Vbus are the fourth terminal 223; the second side signal terminal is a ground signal terminal GND, a transmission signal terminal Rx1+, a transmission signal terminal Rx1-, a power signal terminal Vbus, an auxiliary signal terminal SUB2, a transmission signal terminal D-, a transmission signal terminal D +, a configuration signal terminal CC2, a power signal terminal Vbus, a transmission signal terminal Tx2-, a transmission signal terminal Tx2+ and a ground signal terminal GND in sequence along the Y-axis direction, wherein the adjacent power signal terminal Vbus and configuration signal terminal CC2 are second terminals, and the adjacent auxiliary signal terminal SUB2 and power signal terminal Vbus are third terminals.

Referring to fig. 5 and 8, fig. 8 is an enlarged schematic view of a position III on the electrical connector body 20 shown in fig. 5. 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 close to the tongue plate 211 relative to the first side surface 2131b, and the first side surface 2131b is inclined to a greater extent than the first bottom surface 2131a is inclined to the plane of the first surface 2111, that is, a first included angle α 1 formed by the first side surface 2131b and the plane of the first surface 2111 is smaller than a second included angle α 2 formed by 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 gentler than the first side surface 2131b, so that moisture can easily spread into the first notch 2131, and corrosion of the signal terminal 21 on the first surface 2111 side can be reduced. 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, and the third side surface 2133b is inclined to a greater degree than the fourth bottom surface 2133a is inclined relative to the plane of the first surface 2111, i.e., the fourth bottom surface 2133a is more gradually adjacent to the tongue plate 211 than the third side surface 2133b, so that moisture can easily spread into the fourth notch 2133. In this embodiment, the first included angle α 1 and the second included angle α 2 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, and the second side surface 2132b is inclined to a greater extent than the second bottom surface 2132a is inclined relative to the plane of the second surface 2112, i.e., the second bottom surface 2132a is more gradual relative to the second side surface 2132b near the flap 211, so that moisture can 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, and the fourth side surface is inclined to a greater degree than the third bottom surface relative to the plane of the second surface 2112, i.e., the third bottom surface near the tongue plate 211 is more gradual than the fourth side surface, so that moisture can easily spread into the third notch.

Referring to fig. 4 again, in the embodiment of the present application, the electrical connector 100 further includes a reinforcing plate 30, and the reinforcing plate 30 is embedded in the insulating main body 21. The reinforcing plate 30 has a strength greater than that of the insulating body 21 to reinforce the strength of the insulating body 21. Specifically, the reinforcing plate 30 is at least partially embedded in the tongue plate 211 and at least partially embedded in the base 212, so as to enhance the fixing effect between the tongue plate 211 and the base 212 and avoid the problem that the tongue plate 211 is broken relative to the base 212 due to multiple plugging processes of the electrical connector 100 and the butt end connector.

In some embodiments, the stiffener 30 is a metal plate made of a metal material. The surface of the reinforcing plate 30 is covered with an insulating material, so that the problem of short circuit between different signal terminals 22 caused by the contact between the reinforcing plate 30 and the signal terminals 22 is avoided, the normal transmission of each signal of the electric connector 100 is ensured, the corrosion caused by electrochemical reaction generated between the signal terminals 22 due to the short circuit between different signal terminals 22 is avoided, and the service life of the electric connector 100 is prolonged.

Referring to fig. 9, fig. 9 is a schematic structural diagram of an electrical connector 100 according to another embodiment of the present application, cut along a direction II-II in fig. 4. The electrical connector 100 of the embodiment shown in fig. 9 differs from the electrical connector 100 of the embodiment shown in fig. 4 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 and the first surface 2111 are coplanar, that is, a second included angle between the first bottom surface 2131a and the first surface 2111 is 180 °, an included angle between a plane of the first side surface 2131b and a plane of the first surface 2111 is a first included angle, and the first included angle is an obtuse angle. The connecting section 22b of at least some of the first side signal terminals 22 includes a bent section 2231. In the embodiment of the present application, the first terminal 221 and the fourth terminal 223 are both first-side signal terminals. The connection section 22b of the first terminal 221 is a first connection section, and the connection section 22b of the fourth terminal is a fourth connection section. In the embodiment of the present application, at least the first connection section of the first terminal 221 and the fourth connection section of the fourth terminal of the first side signal terminals include the bent section 2231, or the connection sections 22b of all the first side signal terminals may include the bent section 2231. The bent section 2231 is connected to the contact section 22a, and the bent section 2231 is bent toward the inside of the insulating main body 22 relative to the contact section 22a, so as to prevent the connection section 22b of the first side signal terminal from being exposed from the first bottom surface 2131a or the fourth bottom surface 2133a, and when impurities such as water or particles enter the first notch 2131 or the fourth notch 2133, the impurities such as water or particles will not corrode the signal terminal.

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, and therefore, the first terminal 221 and the fourth terminal 223 include a bent section 2231, and the bent section 2231 is bent toward the interior of the insulating main body 21 relative to the contact section 22a, so as to ensure that when the first bottom surface 2131a and the fourth bottom surface 2133a are coplanar with the first surface 2111, the bent section 2231 can be embedded in the base 212, that is, the bent section 2231 of the first terminal 221 is located on a side of the first bottom surface 2131a facing the fourth surface 2122, and the connection section 22b of the first terminal 221 does not expose the first bottom surface 2131 a; the bent section 2231 of the fourth terminal 223 is located on a side of the fourth bottom surface 2133a facing the fourth surface 2122, and the connecting segment 22b of the fourth terminal 223 is not exposed from the fourth bottom surface 2133 a. When moisture enters the electrical connector 100, the first bottom surface 2131a and the fourth bottom surface 2133a are coplanar with the first surface 2111, so that the moisture can be more easily spread into the first bottom surface 2131a and the fourth bottom surface 2133a, thereby reducing the contact between the contact segment 22a of the signal terminal 22 and the moisture and reducing the corrosion of the signal terminal 22. Moreover, since the bent section 2231 is bent toward the second surface 2112 and embedded in the base 212, moisture can be isolated from the signal terminal 22 by the insulating material covering the bent section 2231, so as to prevent the signal terminal 22 from being corroded due to the contact of moisture with the connecting section 22b of the signal terminal 22.

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 section 22b of at least some of the second side signal terminals includes a bent section 2232. In the embodiment of the present application, the second terminal and the third terminal are both second-side signal terminals. The connection section 22b of the second terminal is a second connection section, and the connection section 22b of the third terminal is a third connection section. Only the second connection segment and the third connection segment may include the bent segment 2232, or all of the connection segments 22b of the second side signal terminals may include the bent segments 2232. The bent section 2232 is connected to the contact section 22a, and the bent section 2231 is bent toward the first surface 2111 relative to the contact section 22 a. Since the bent section 2231 is bent toward the first surface 2111 relative to the contact section 22a, it can be ensured that when the second bottom surface 2132a and the third bottom surface 2134a are coplanar with the second surface 2112, the bent section 2232 can be embedded in the base 212, that is, the bent section 2232 of the second terminal is located on a side of the second bottom surface 2132a facing the third surface 2121, and the connection section 22b of the second terminal does not expose the second bottom surface 2132 a; the bent section 2232 of the third terminal is located on a side of the third bottom surface 2134a facing the third surface 2121, and the connecting section 22b of the third terminal is not exposed from the third bottom surface 2134 a. When moisture enters the electrical connector 100, the second bottom surface 2132a and the third bottom surface 2134a are coplanar with the second surface 2112, so that the moisture can be more easily spread into the third region 2132 a. Moreover, since the bent section 2232 is bent toward the third surface 2121 and embedded in the base 212, that is, the bent section 2232 does 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 bent section 2232, so as to prevent the signal terminal 22 from being corroded due to the contact between the moisture and the signal terminal 22.

Referring to fig. 10 and fig. 10a and 10b, fig. 10 is a schematic structural view of an electrical connector according to another embodiment of the present disclosure taken along a direction II-II in fig. 4, fig. 10a is an enlarged view of a position IV in fig. 10, and fig. 10b is a side view of fig. 10. The embodiment shown in fig. 10 differs from the embodiment shown in fig. 4 in that: a space exists between the contact section 22a of at least one signal terminal 22 of the plurality of signal terminals 22 and the base 212. In the embodiment of the present application, since there is a distance L between the contact section 22a of the signal terminal 22 and the plane of the first limiting surface 2123a, when moisture is gathered at the position of the stepped structure, the water is located at the position of the distance L between the contact section 22a and the plane of the first limiting surface 2123a, that is, the moisture does not contact with the contact section 22a of the signal terminal 22, so as to prevent the moisture from entering the electrical connector 100 to accelerate corrosion of the signal terminal 22.

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 from the limiting surface 2123, so that the contact between the first terminal 221, the fourth terminal 223, the second terminal and the third terminal and moisture or particle impurities is reduced. In this embodiment, the first terminal 221, the fourth terminal 223, and the second terminal and the third terminal are all signal terminals that are relatively susceptible to electrochemical reaction corrosion, and corrosion of the signal terminal 22 in the electrical connector 100 can be reduced by reducing contact between the first terminal 221, the fourth terminal 223, and the second terminal and the third terminal with moisture or particulate impurities.

In some embodiments, the connecting section 22b of the signal terminal 22, in which the contact section 22a and the plane of the first limiting surface 2123a are disposed at an interval, includes a bent section 2233, and the bent section 2233 is bent toward the inside of the insulating main body 21 relative to the contact section 22a, so as to ensure that the bent section 2233 is embedded in the insulating main body 21, that is, the bent section 2233 is not exposed from the insulating main body 21, and the bent section 2233 is covered with an insulating material. In this embodiment, the bent section 2233 is partially embedded in the tongue plate 211 and partially embedded in the base 212. The portion of the bent section 2233 embedded in the tongue plate 211 corresponds to a position of a distance between the contact section 22a and a plane of the first limiting surface 2123 a. When moisture enters the electrical connector 100, the moisture is located at a position of a distance between the contact section 22a and a plane where the first limiting surface 2123a is located, and the moisture can be separated by the insulating material covering the bent section 2233, so that corrosion of the signal terminals 22 by the moisture is avoided, and corrosion of the signal terminals 22 accelerated by the moisture short-circuiting the adjacent signal terminals 22 is avoided.

In this application, through forming the breach on base 212, when having water or some granule impurity in electric connector 100, will peg graft end connector and the electric connector 100 of this application, to the in-process of end connector insert electric connector 100, water or granule impurity in electric connector 100 can be pushed in the breach to reduce the water or the quantity of impurity on the signal terminal 22, and then can alleviate or avoid the corruption of signal terminal 22. When the amount of water entering the electrical connector 100 is small, a small amount of water forms a water film in the electrical connector 100 that can extend into the notch by the surface tension, thereby reducing the area of the water film in contact with the contact segment 22a of the signal terminal 22 and reducing corrosion at the position of the signal terminal 22.

In the above, it should be noted that the preferred embodiments of the present application are described by way of example only, and it should be understood that various modifications and improvements can be made by those skilled in the art without departing from the principle of the present application, and such modifications and improvements are also considered to be within the scope of the present application.
