[0023] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.
[0024] See also Figures 1 to 3 , Figure 1 A schematic diagram of the structure of the electrical connector provided in the embodiment of the present application, Figure 2 for Figure 1 A schematic diagram of the structure of the electrical connector from another perspective is shown, Figure 3 for Figure 1 The exploded schematic diagram of the structure of the electrical connector shown. The embodiment of the present application provides an electrical connector 10, including a body 110, a tongue plate 120 and a terminal 130, wherein the body 110 has a receiving space 111; the tongue plate 120 is connected to the body 110 and disposed in the receiving space 111; the terminal 130 includes a contact portion 131 exposed from the tongue plate 120 and a connecting portion 132 hidden in the tongue plate 120. The connecting portion 132 includes a connecting structure and a reinforcing structure, wherein the reinforcing structure includes a first reinforcing structure connected to the connecting structure and a second reinforcing structure connected to the first reinforcing structure, and the second reinforcing structure is spaced apart from the contact portion. The terminal 130 in the electrical connector 10 of the embodiment of the present application includes a reinforcing structure hidden in the tongue plate 120, which can support the tongue plate 120, and when the tongue plate is subjected to external force, the structural strength of the tongue plate 120 can be improved to prevent the tongue plate from breaking due to the external force.
[0025] The terminal 130 may include a first terminal, see Figures 1 to 5 , Figure 4 A schematic diagram of the structure of the first terminal provided in an embodiment of the present application, Figure 5 A schematic structural diagram of the connection between the first terminal and the tongue plate provided in an embodiment of the present application.
[0026] The first terminal 20 includes a contact portion 21 exposed from the tongue plate 120 and a connecting portion 22 hidden in the tongue plate 120 ( Figure 5 The connecting portion 22 includes a connecting structure 220 and a reinforcing structure. The reinforcing structure includes a first reinforcing structure 221 connected to the connecting structure 220 and a second reinforcing structure 222 connected to the first reinforcing structure 221. The second reinforcing structure 222 is spaced apart from the contact portion 21.
[0027] The tongue plate 120 includes a root 121 connected to the main body 110 and a protrusion 122 connected to the root 121 and protruding from the accommodating space 111, the contact portion 21 is exposed on the protrusion 122, and the second reinforcement structure 222 includes a first sub-reinforcement portion 2221 and a second sub-reinforcement portion 2222, the first sub-reinforcement portion 2221 is connected to the first reinforcement structure 221 and hidden in the root 121, and the second sub-reinforcement portion 2222 is connected to the first sub-reinforcement portion 2221 and hidden in the protrusion 122.
[0028] In some embodiments, in order to improve the reinforcing effect of the reinforcing structure, the size of the second sub-reinforcing portion 2222 in the first direction is greater than or equal to the size of the contact portion 21 in the first direction, and the first direction is the direction in which the protrusion 122 protrudes toward the accommodating space 111. The second sub-reinforcing portion hidden in the protrusion 122 extends to the front end of the tongue plate 120, increasing the connection area between the first terminal 20 and the tongue plate 120, not only improving the connection strength between the first terminal 20 and the tongue plate 120, but also playing a supporting role for the tongue plate protrusion 122, thereby improving the overall structural strength of the tongue plate 120. It is understandable that in some other embodiments, the size of the second sub-reinforcing portion 2222 in the first direction may also be smaller than the size of the contact portion 21 in the first direction. The size of the second sub-reinforcing portion 2222 in the first direction may be designed according to the structural strength requirements of the tongue plate 120 and the actual structure of the tongue plate protrusion 122.
[0029] In some embodiments, in order to improve the reinforcing effect of the reinforcing structure and reduce the size of the tongue plate protrusion 122, the size of the second sub-reinforcement 2222 in the first direction is larger than the size of the second sub-reinforcement 2222 in the second direction, the size of the second sub-reinforcement 2222 in the second direction is larger than the size of the second sub-reinforcement 2222 in the third direction, any two directions among the first direction, the second direction and the third direction are perpendicular to each other, and the second direction is the thickness direction of the tongue plate. Not only can the size of the tongue plate protrusion 122 in the third direction be reduced, but also when the protrusion 122 is subjected to a bending external force along the second direction, since the second sub-reinforcement 2222 has a larger size in the second direction, it can better withstand the bending force and play a supporting role for the tongue plate protrusion 122.
[0030] In some embodiments, in order to increase the connection strength between the first terminal 20 and the protrusion 122, and thus improve the overall structural strength of the tongue plate 120, the second sub-reinforcement portion 2222 includes a first portion 2224 and a second portion 2225 arranged along the first direction, the first portion 2224 is connected to the first sub-reinforcement portion 2221, the first portion 2224 is arranged between the first sub-reinforcement portion 2221 and the second portion 2225, the size of the first portion 2224 in the second direction is greater than the size of the second portion 2225 in the second direction, and the connection area between the first terminal 20 and the protrusion 122 can be increased, thereby increasing the connection strength between the first terminal 20 and the protrusion 122. It can be understood that in some other embodiments, the size of the second portion 2225 in the second direction is greater than the size of the first portion 2224 in the second direction, which can be designed according to the structural strength requirements of the tongue plate 120 and the actual structure of the tongue plate protrusion 122.
[0031] In some embodiments, in order to further increase the connection strength between the first terminal 20 and the protrusion 122, and thus improve the overall structural strength of the tongue plate 120, a groove 2226 is provided at the connection between the first sub-reinforcement portion 2221 and the second sub-reinforcement portion 2222. The groove 2226 can be engaged with the protrusion 122, and the connection area between the first terminal 20 and the protrusion 122 can be increased, thereby increasing the connection strength between the first terminal 20 and the protrusion 122.
[0032] In some embodiments, in order to further improve the overall structural strength of the tongue plate 120, the second reinforcement structure 222 further includes a third sub-reinforcement portion 2223, the third sub-reinforcement portion 2223 is connected to the first sub-reinforcement portion 2221 and is hidden in the root portion 121, the first sub-reinforcement portion 2221 is disposed between the third sub-reinforcement portion 2223 and the second sub-reinforcement portion 2222, and the first reinforcement structure 221 and the third sub-reinforcement portion 2223 are spaced apart. The third sub-reinforcement portion 2223 is disposed at the root portion 121 and spaced apart from the first reinforcement structure 221, which increases the volume of the second reinforcement structure 222 in the root portion 121, thereby enhancing the connection strength between the protrusion 122 and the root 121. When the protrusion 122 is subjected to a bending external force along the second direction, the protrusion 122 can withstand a greater bending external force due to the enhanced connection strength between the protrusion 122 and the root 121.
[0033] In some embodiments, the first reinforcement structure 221 may include a bending portion bent toward the second reinforcement structure 222, one end 2211 of the bending portion is connected to the second reinforcement structure 222, and the other end 2212 is connected to the connection structure 220. The bending portion can not only increase the connection area between the first reinforcement structure 221 and the root 121, but also increase the size of the reinforcement structure in the second direction (longitudinal direction), and can better withstand the bending force along the second direction on the tongue plate 120.
[0034] In some embodiments, the terminal may include a second terminal. Figures 1 to 3 and Figure 6 to Figure 7 , Figure 6 A schematic diagram of the structure of the second terminal provided in an embodiment of the present application, Figure 7 A schematic structural diagram of the connection between the second terminal and the tongue plate provided in an embodiment of the present application.
[0035] The second terminal 30 includes a contact portion 30 exposed from the tongue plate 120 and a connecting portion 32 hidden in the tongue plate 120 ( Figure 7 The connecting portion 32 includes a connecting structure 320 and a reinforcing structure. The reinforcing structure includes a first reinforcing structure 321 connected to the connecting structure 320 and a second reinforcing structure 322 connected to the first reinforcing structure 321. The second reinforcing structure 322 is spaced apart from the contact portion 31.
[0036] The tongue plate 120 includes a root portion 121 connected to the body 110 and a protrusion 122 connected to the root portion 121 and protruding from the accommodation space 111, the contact portion 31 is exposed from the protrusion 122, the first reinforcement structure 321 is hidden in the root portion 121, the second reinforcement structure 322 is hidden in the protrusion 122, the size of the second reinforcement structure 322 in the first direction is smaller than the size of the contact portion 31 in the first direction, and the first direction is the direction in which the protrusion 122 protrudes toward the accommodation space 111. The structural strength of the tongue plate 120 can be improved while saving the material of the terminal.
[0037] In some embodiments, the size of the second reinforcement structure 322 in the second direction is smaller than the size of the second reinforcement structure 322 in the third direction, any two of the first direction, the second direction and the third direction are perpendicular to each other, and the second direction is the thickness direction of the tongue plate. The size of the reinforcement structure in the third direction (transverse direction) can be increased, and the portion of the protrusion 122 provided with the second reinforcement structure 322 can be made thinner, thereby reducing the thickness of the portion of the protrusion 122.
[0038] See also Figures 1 to 8 , Figure 8 A schematic diagram of the structure of the terminal provided in an embodiment of the present application. The terminal includes a first terminal 20 and a second terminal 30, wherein the first terminal 20 may be the first terminal described in the above embodiment, and the second terminal 30 may be the second terminal described in the above embodiment. The first terminal 20 and the second terminal 30 are arranged at intervals on the tongue plate 120. The first terminal 20 and the second terminal 30 are arranged on the tongue plate 120 along a third direction, and the third direction is the third direction described above.
[0039] The electrical connector 10 provided in the embodiment of the present application may include two first terminals 20 and two second terminals 30, the two first terminals 20 are respectively arranged at the periphery of the tongue plate 120, and two second terminals 30 are arranged between the two first terminals 20. By arranging the first terminal 20 whose reinforcement structure extends to the front end of the tongue plate 120 at the periphery of the tongue plate 120, the supporting force of the periphery 120 of the tongue plate can be improved, and the second terminal 30 whose reinforcement structure is close to the root of the tongue plate 120 is arranged in the middle of the tongue plate, that is, between the two first terminals 20, so as to improve the supporting force at the root of the tongue plate 120, the structural strength of the tongue plate can be improved from different directions and different positions.
[0040] In some embodiments, in order to make the reinforcement structure bear force uniformly, the two first terminals 20 are symmetrically arranged with the center line of the tongue plate 120 as the symmetry axis, and the two second terminals 30 are symmetrically arranged with the center line of the tongue plate as the symmetry axis, so as to improve the overall structural strength of the tongue plate 120.
[0041] In some embodiments, the electrical connector 10 further includes a third terminal 40, which is arranged along the center line on the tongue plate 120. The third terminal 40, the two first terminals 20 and the two second terminals 30 can form a 5P electrical connector, which can be used as a high-current charger.
[0042] It can be understood that the electrical connector provided in the embodiment of the present application may include only the above-mentioned first terminal, or may include only the first terminal and the third terminal, or may include only the second terminal, or may include only the second terminal and the third terminal. In other words, the specific structure and quantity of the terminals can be set according to the actual structure of the tongue plate 120 and the actual functional requirements of the electrical connection.
[0043] The embodiment of the present application provides an electrical connector, which provides a reinforcement structure on the terminal and connects the terminal to the tongue plate by injection molding. The relationship between the reinforcement structure hidden in the tongue plate and the tongue plate is equivalent to that between steel bars and concrete, which can improve the overall structural strength of the tongue plate. When the tongue plate is subjected to bending forces from above and below, the reinforcement structure can support the tongue plate and play a supporting role to prevent the protruding part of the tongue plate from breaking from the root due to excessive bending forces. Compared with the tongue plate of an electrical connector without a reinforcement structure, the structural strength of the tongue plate of the electrical connector provided in the embodiment of the present application can be doubled. For example, the tongue plate of an electrical connector without a reinforcement structure can withstand a bending force of 30N, while the tongue plate of the electrical connector provided in the embodiment of the present application can withstand a bending force of 60N, which can improve the reliability of the product.
[0044] The embodiment of the present application also provides a charger, including a charging circuit and the electrical connector as described above, wherein the charging circuit is electrically connected to the terminal.
