The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0048] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides various specific processes and examples of materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0049] Hereinafter, a terminal 100 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0050] like Figure 1-Figure 7 As shown, the terminal 100 includes a main body 1, and the main body 1 includes a mating portion 11. The mating portion 11 has an elastic arm 111 and a stop member 112. The elastic arm 111 is used to electrically contact the first connector 101, so as to realize the electrical connection between the terminal 100 and the first connector 101, and the elastic arm 111 has a certain elastic force to ensure the elastic contact force between the elastic arm 111 and the first connector 101; as the first connector 101 cooperates with the mating portion 11, the first connector 101 pushes the elastic arm 111 to deform the elastic arm 111 to provide a mating space for the first connector 101, and at the same time, the elastic arm 111 has a tendency to restore its original shape to apply a force to the first connector 101, so that when the elastic arm 111 is in electrical contact with the first connector 101, the elastic arm 111 squeezes the first connector 101 to ensure the stability of the electrical contact between the elastic arm 111 and the first connector 101.

[0051] The stop member 112 is used to provide an elastic supporting force for the elastic arm 111 to resist the first connector 101. When the elastic arm 111 is in electrical contact with the first connector 101, the stop member 112 can apply a force to the elastic arm 111 so that the elastic arm 111 tends to approach the first connector 101, thereby increasing the contact force between the elastic arm 111 and the first connector 101, which is beneficial to increase the friction between the elastic arm 111 and the first connector 101, thereby improving the reliability of the electrical contact between the elastic arm 111 and the first connector 101, reducing the risk of separation between the mating part 11 and the first connector 101, ensuring stable cooperation between the first connector 101 and the terminal 100, and further ensuring the reliability and stability of the electrical connection between the terminal 100 and the first connector 101.

[0052] Among them, the stop member 112 and the elastic arm 111 are respectively connected to the side walls on different sides of the mating part 11, so that the elastic arm 111 and the stop member 112 are arranged more dispersedly, so as to disperse the force applied to the mating part 11 by the first connecting member 101, improve the force on the mating part 11, and at the same time help to enhance the flexibility of the position setting of the stop member 112, so as to realize the structural diversification design of the terminal 100 and better meet the actual differentiated needs.

[0053] For example, in Figure 2 and Figure 3 In the example, the elastic arm 111 is connected to the top side wall of the mating portion 11, and the stop member 112 is connected to the left side wall or the right side wall of the mating portion 11. Of course, the stop member 112 can also be connected to the bottom side wall of the mating portion 11.

[0054] It can be understood that when the elastic arm 111 is in electrical contact with the first connecting member 101 , the stop portion 1121 directly or indirectly applies a force along the third direction toward the first connecting member 101 to the elastic arm 111 . When the elastic arm 111 is not electrically connected to the first connecting member 101, the stop member 1121 can directly or indirectly apply a force to the elastic arm 111 so that the elastic arm 111 has a tendency to deflect toward the position of the first connecting member 101 where the elastic arm 111 completes the electrical connection. This allows the stop member 1121 to provide a greater force when the elastic arm 111 completes the electrical connection with the first connecting member 101, thereby ensuring a reliable and stable electrical connection. Alternatively, when the elastic arm 111 is not electrically connected to the first connecting member 101, the stop member 112 can be spaced apart from or in contact with the elastic arm 111. In this case, the stop member 112 may not apply a force to the elastic arm 111, and only after the elastic arm 111 contacts the first connecting member 101, the stop member 112 applies a force to the elastic arm 111 to ensure a reliable connection between the elastic arm 111 and the first connecting member 101.

[0055] In short, during the entire process from the first connecting member 101 starting to cooperate with the elastic arm 111 to the first connecting member 101 and the elastic arm 111 completing the electrical connection, the stop member 112 can directly or indirectly apply a force to the elastic arm 111 at any time to increase the contact pressure between the elastic arm 111 and the first connecting member 101; it can be seen that when the elastic arm 111 cooperates with the first connecting member 101, the stop member 112 is deformed because the stop member 112 is subjected to the force applied by the first connecting member 101 through the elastic arm 111, and the stop member 112 applies a reaction force to the elastic arm 111, and the reaction force makes the elastic arm 111 have a movement tendency to approach the first connecting member 101, thereby increasing the squeezing force between the elastic arm 111 and the first connecting member 101.

[0056] When the terminal 100 is used in an electrical connector, it can ensure that the electrical connector is suitable for complex working conditions and complex usage environments (such as high-frequency vibration, hot and cold environments, high dust and high humidity environments, etc.), and still ensure the reliability and stability of the electrical connection of the electrical connector.

[0057] According to the terminal 100 of the embodiment of the present invention, a stop member 112 and an elastic arm 111 are respectively connected to the side walls on different sides of the mating portion 111, and the stop member 112 is used to apply a force to the elastic arm 111 to increase the contact force between the elastic arm 111 and the first connector 101 when the elastic arm 111 is electrically connected to the first connector 101, thereby improving the stability and reliability of the electrical contact between the first connector 101 and the elastic arm 111, ensuring that the electrical connection between the first connector 101 and the terminal 100 is stable and reliable, so that the terminal 100 can be applied to complex working conditions and complex usage environments, thereby improving the applicability of the terminal 100.

[0058] Compared to some technologies, in order to improve the connection reliability between the first connecting member and the terminal, the elastic arm and the supporting member are connected to the side wall on the same side of the mating part, the present application connects the elastic arm 111 and the stop member 112 to the side walls on different sides of the mating part 11 respectively, so that the bearing capacity of the stop member 112 is stronger, which is conducive to the stop member 112 providing a stronger supporting force, thereby effectively improving the elastic contact force between the first connecting member 101 and the elastic arm 111, and improving the reliability and stability of the connection between the terminal 100 and the first connecting member 101.

[0059] In short, compared with the solution in which the elastic arm relies solely on its own elastic ability to electrically connect with the first connector, and the solution in which the elastic arm and the support member are connected to the side wall on the same side of the mating part, the stop member 112 in the present application can increase the continuously increasing elastic supporting force, and the supporting ability is stronger, so as to effectively improve the elastic contact between the elastic arm 111 and the first connector 101, thereby improving the connection reliability and stability between the terminal 100 and the first connector.

[0060] In some embodiments, Figure 2 and Figure 3 As shown, the elastic arm 111 extends along the first direction, and the stop member 112 includes a stop portion 1121 and a first connecting portion 1122. The stop portion 1121 is provided on one side of the elastic arm 111 in the third direction, and the first connecting portion 1122 is connected to the connecting side wall 1103 of the mating portion 11 in the second direction. The stop portion 1121 can be used to apply a force along the third direction toward the first connecting member 101 to the elastic arm 111. When the elastic arm 111 is in electrical contact with the first connecting member 101, the stop portion 1121 is located on the side of the elastic arm 111 that is away from the first connecting member 101. The third direction is perpendicular to the first direction and the second direction respectively, and the first direction is perpendicular to the second direction.

[0061] The following description is made by taking the first direction as the front-to-back direction, the second direction as the left-to-right direction, and the third direction as the up-to-down direction as an example. After reading the following scheme, those skilled in the art can easily understand other implementation schemes. Figure 1-Figure 7 In the example, the elastic arm 111 extends along the front-to-back direction, and the first connector 101 is suitable for being plugged into the lower side of the elastic arm 111. For example, the first connector 101 is suitable for contacting the lower surface of the elastic arm 111. The stop portion 1121 is arranged on the upper side of the elastic arm 111. The first connecting portion 1122 is connected to the connecting side wall 1103 of the plug-in portion 11. The connecting side wall 1103 is located on the left or right side of the plug-in portion 11. The stop portion 1121 is configured as follows: when the elastic arm 111 is in electrical contact with the first connector 101, the stop portion 1121 applies a downward force to the elastic arm 111 to increase the elastic contact force between the elastic arm 111 and the first connector 101, thereby ensuring that the elastic arm 111 and the first connector 101 are stably and reliably matched.

[0062] In some embodiments, Figure 1 , Figure 5 and Figure 6As shown, the connecting side wall 1103 is formed with a notch 1103a, and the notch 1103a can penetrate the connecting side wall 1103 along the thickness direction of the connecting side wall 1103, and the notch 1103a has a first edge 1103b and two second edges 1103c, and the two second edges 1103c are respectively arranged at two ends of the first edge 1103b in the first direction, and the first connecting portion 1122 is connected to the first edge 1103b, and the first connecting portion 1122 and the two second edges 1103c are respectively arranged at intervals, so as to increase the height of the first connecting portion 1122 in the third direction while ensuring the height of the connecting side wall 1103 in the third direction. that is, even if the height of the connecting side wall 1103 in the third direction is greater, the length of the first connecting portion 1122 in the third direction will not be shortened too much, thereby facilitating the increase of the total length of the stop member 112, facilitating the improvement of the deformation capacity of the cantilever stop member 112, and facilitating the gradual deformation of the stop member 112 during the cooperation between the first connecting member 101 and the elastic arm 111, so as to increase the squeezing force between the elastic arm 111 and the first connecting member 101, while further enabling the first connecting member 101 to have a suitable installation resistance, thereby further improving the installation feel of the first connecting member 101.

[0063] In some embodiments, Figure 1 , Figure 3-Figure 5 As shown, the first connection portion 1122 extends along the third direction, and the first connection portion 1122 is directly connected to the stop portion 1121. At this time, the stop member 112 can be roughly formed into an L-shaped structure. The stop member 112 has a simple structure, is easy to process, and has good elastic deformation ability.

[0064] For example, in Figure 1-Figure 3 In the example, there is one stop member 112, the stop portion 1121 is arranged on the upper side of the elastic arm 111, and the stop portion 1121 extends in the left-right direction, the first connection portion 1122 is connected to the right side of the stop portion 1121, and the first connection portion 1122 is connected to the connecting side wall 1103 on the right side of the mating portion 11, and the first connection portion 1122 extends in the up-down direction; of course, when there is one stop member 112 and the stop portion 1121 extends in the left-right direction, the first connection portion 1122 can also be connected to the left side of the stop portion 1121, and the first connection portion 1122 is connected to the connecting side wall 1103 on the left side of the mating portion 11, and the first connection portion 1122 also extends in the up-down direction; or, when the stop portion 1121 extends in the left-right direction, there are two stop members 112, and the two stop members 112 are arranged at intervals in the left-right direction (such as Figure 4 As shown) or a contact setting, wherein the first connection portion 1122 of one stop member 112 is connected to the connecting side wall 1103 on the left side of the mating portion 11, and the first connection portion 1122 of the other stop member 112 is connected to the connecting side wall 1103 on the right side of the mating portion 11.

[0065] Of course, the arrangement of the first connection portion 1122 is not limited thereto; for example, the first connection portion 1122 may also extend along the second direction, and in this case, the stop member may be roughly formed as a flat plate structure.

[0066] In some embodiments, Figure 2-Figure 5 As shown, the width w of the stop portion 1121 in the first direction is greater than the thickness t of the stop portion 1121 in the third direction, ensuring that the stop member 112 has appropriate bending rigidity so that the stop member 112 provides appropriate elastic force.

[0067] Optionally, in Figure 1-Figure 5 In the example, the terminal 100 is an integrally molded part. For example, the terminal 100 can be formed by multiple bending of a metal plate. The thickness t of the stop portion 1121 in the third direction can correspond to the thickness of the metal plate. The width w of the stop portion 1121 in the first direction can be specifically set according to actual needs so that the stop portion 1121 has suitable bending stiffness. The design of w>t will not limit the molding method of the terminal 100.

[0068] Of course, in other embodiments of the present application, the width w of the stopping portion 1121 in the first direction may also be equal to the thickness t of the stopping portion 1121 in the third direction.

[0069] In some embodiments, Figure 6 and Figure 7 As shown, the stop member 112 also includes a second connecting portion 1123, which connects the stop member 1121 and the first connecting portion 1122. The first connecting portion 1122 extends along the third direction, and the second connecting portion 1123 extends along the first direction, which is beneficial to increase the total length of the stop member 112, and is convenient for improving the deformation capacity of the cantilever stop member 112. It is also beneficial for the stop member 112 to gradually deform during the cooperation process between the first connecting member 101 and the elastic arm 111, so as to increase the squeezing force between the elastic arm 111 and the first connecting member 101, and further make the first connecting member 101 have a suitable installation resistance, thereby further improving the installation feel of the first connecting member 101.

[0070] For example, in Figure 6 and Figure 7In the example, there is one stop member 112, and the stop member 112 includes a stop portion 1121, a first connection portion 1122, and a second connection portion 1123. The stop portion 1121 is arranged on the upper side of the elastic arm 111, and the stop portion 1121 extends in the left-right direction, the first connection portion 1122 is arranged on the right side of the stop portion 1121, and the first connection portion 1122 is connected to the connecting side wall 1103 on the right side of the mating portion 11, the first connection portion 1122 extends in the up-down direction, and the second connection portion 1123 extends in the front-to-back direction and connects the stop portion 1121 and the first connection portion 1122; of course, when there is one stop member 112 and the stop portion 1121 extends in the left-right direction, the first connection portion 1122 can also It is arranged on the left side of the stop portion 1121, and the first connection portion 1122 is connected to the connecting side wall 1103 on the left side of the mating portion 11. At this time, the first connection portion 1122 also extends in the up-down direction, and the second connection portion 1123 also extends in the front-to-back direction and connects the stop portion 1121 and the first connection portion 1122; or, when the stop portion 1121 extends in the left-right direction, the stop portion 1121 can also be two, and the two stop members 112 are arranged at intervals or in contact with each other in the left-right direction, wherein the first connection portion 1122 of one of the stop members 112 is connected to the connecting side wall 1103 on the left side of the mating portion 11, and the first connection portion 1122 of the other stop member 112 is connected to the connecting side wall 1103 on the right side of the mating portion 11.

[0071] It can be understood that when the second connection portion 1123 extends in the front-to-back direction, the second connection portion 1123 can be connected to the front end or the rear end of the first connection portion 1122 .

[0072] In some embodiments, Figure 6 and Figure 7 As shown, the width w' of the stop portion 1121 in the first direction is smaller than the thickness t' of the stop portion 1121 in the third direction, thereby ensuring that the stop member 112 has suitable bending stiffness and facilitating a certain twisting of the stop member 112 under the action of the elastic arm 111, so that the second connecting portion 1122 also undergoes a certain deformation, so that the stop member 112 provides a reasonable force.

[0073] Optionally, in Figure 6 and Figure 7 In the example, the terminal 100 is an integrally molded part. For example, the terminal 100 can be formed by multiple bending of a metal plate. The thickness t' of the stop portion 1121 in the third direction can correspond to the thickness of the metal plate, and the width w' of the stop portion 1121 in the first direction can be specifically set according to actual needs so that the stop portion 1121 has appropriate bending stiffness; then the design of w'<t' will not limit the molding method of the terminal 100.

[0074] Of course, in other embodiments of the present application, when the stop member 112 includes the second connecting portion 1123 , the width w′ of the stop portion 1121 in the first direction may also be equal to the thickness t′ of the stop portion 1121 in the third direction.

[0075] In some embodiments, a stop member 112 is disposed on both sides of the elastic arm 111 in the second direction, and the two stop members 112 are disposed opposite to each other along the second direction (eg, Figure 4 and Figure 5 As shown) or staggered arrangement, when the elastic arm 111 makes point contact with the first connecting member 101, the two stop members 112 both apply a force to the elastic arm 111 along the third direction toward the first connecting member 101, so as to further increase the force between the elastic arm 111 and the first connecting member 101, further increase the friction between the elastic arm 111 and the first connecting member 101, thereby further ensuring the stability of the electrical contact between the elastic arm 111 and the first connecting member 101.

[0076] Optionally, when the two stop members 112 are staggered along the second direction, the two stop members 112 can be staggered in the first direction, and the orthographic projections of the two stop members 112 along the second direction at least partially do not overlap, for example, the orthographic projections of the two stop members 112 along the second direction are spaced apart.

[0077] It is understandable that the structures of the stop members 112 on both sides of the elastic arm 111 may be the same or different.

[0078] For example, in Figure 4 and Figure 5 In the example, the mating part 11 has two stop members 112, each stop member 112 includes a stop portion 1121 and a first connecting portion 1122, the stop portions 1121 of the two stop members 112 extend toward each other in the left-right direction respectively, and the two stop portions 1121 are spaced apart from each other in the left-right direction, the first connecting portions 1122 of the two stop members 112 both extend in the up-down direction, and the two first connecting portions 1122 are respectively connected to the connecting side walls 1103 on both sides of the mating part 11 in the left-right direction.

[0079] For another example, the mating part 11 has two stop members 112, each of which may include a stop member 1121, a first connection portion 1122 and a second connection portion 1123, the stop members 1121 of the two stop members 112 extend toward each other in the left-right directions respectively, and the two stop members 1121 are spaced apart from each other in the left-right directions, the first connection portions 1122 of the two stop members 112 both extend in the up-down directions, and the two first connection portions 1122 are respectively connected to the two side connecting side walls 1103 of the mating part 11 in the left-right directions, and the second connection portion 1123 extends in the front-to-back direction and is connected between the corresponding stop member 1121 and the corresponding first connection portion 1122.

[0080] In some embodiments, Figure 2-Figure 7 As shown, the two side surfaces of the elastic arm 111 in the third direction are respectively the first side surface S1 and the second side surface S2, the first side surface S1 is suitable for contacting with the first connecting member 101, the stop portion 1121 is arranged on the side where the second side surface S2 is located, and the stop portion 1121 is arranged opposite to the second side surface S2, that is, when the first connecting member 101 is matched with the elastic arm 111, the first connecting member 101 is matched with the side of the elastic arm 111 away from the stop portion 1121, so that the stop portion 1121 applies a force to the elastic arm 111 along the third direction toward the first connecting member 101; and the stop portion 1121 is suitable for contacting the elastic arm 111. The elastic arm 111 applies a first force along the third direction toward the first connecting member 101, and the first connecting member 101 applies a second force along the third direction toward the stop portion 1121 to the elastic arm 111, and the direction of the second force is basically opposite to the direction of the first force. The magnitude of the first force is basically equal to the magnitude of the second force, which is convenient for ensuring that the force applied by the stop portion 1121 on the elastic arm 111 will not reduce the force between the elastic arm 111 and the first connecting member 101 due to the deformation of the elastic arm 111, thereby further ensuring that the electrical connection between the elastic arm 111 and the first connecting member 101 is stable and reliable.

[0081] In some embodiments, Figure 2 , Figure 5 and Figure 7 As shown, the cantilever setting of the stop member 112 can make the stop member 112 have good deformation ability, which is convenient for applying a continuously increasing elastic force to the elastic arm 111, and when the first connecting member 101 is installed, a suitable installation resistance can be applied to the first connecting member 101 through the elastic arm 111. When the first connecting member 101 is installed in place, a suitable elastic extrusion force can be applied to the first connecting member 101 through the elastic arm 111, so as to improve the installation feel of the first connecting member 101 while ensuring that the first connecting member 101 and the elastic arm 111 are reliably connected.

[0082] It can be understood that when the stop member 112 is cantilevered, since the first connecting portion 1122 is connected to the connecting side wall 1103, the end of the first connecting portion 1122 away from the stop member 1121 can be formed as a fixed end of the stop member 112, and the end of the stop member 1121 away from the first connecting portion 1122 can be formed as a free end of the stop member 112.

[0083] For example, during the cooperation between the first connecting member 101 and the elastic arm 111, the first connecting member 101 pushes the elastic arm 111 to deflect the elastic arm 111 toward the stop member 112, and the elastic arm 111 then pushes the stop portion 1121 to deflect, so that the stop member 112 undergoes elastic deformation, and the stop member 112 has a tendency to restore its original shape to apply a force to the elastic arm 111, thereby increasing the force applied by the elastic arm 111 toward the first connecting member 101 to ensure that the electrical contact between the elastic arm 111 and the first connecting member 101 is reliable and stable; when the first connecting member 101 disconnects the electrical connection with the elastic arm 111, the stop member 112 can restore to its original shape to ensure that the electrical connection between the terminal 100 and the first connecting member 101 is stable next time, thereby realizing the reuse of the terminal 100.

[0084] Of course, the present application is not limited to this; in other embodiments, the end of the stop portion 1121 away from the first connecting portion 1122 can also be connected to another connecting side wall 1103 of the mating portion 11, so that the stop member 112 is connected between the two connecting side walls 1103 of the mating portion 11.

[0085] In some embodiments, Figure 1-Figure 7 As shown, the stop member 112 is configured as follows: when the elastic arm 111 is separated from the first connecting member 101, the stop member 112 is spaced apart from the elastic arm 111. Then, in a natural state (when the first connecting member 101 is not installed), the stop member 112 is spaced apart from the elastic arm 111. At this time, the stop member 112 does not apply any force to the elastic arm 111, thereby simplifying the processing technology of the terminal 100.

[0086] For example, when the elastic arm 111 is separated from the first connecting member 101, the stop member 112 is spaced apart from the elastic arm 111 so that a certain distance is reserved between the stop member 112 and the elastic arm 111. At this time, the elastic arm 111 and the stop member 112 can both be in a natural state; during the installation of the first connecting member 101 on the mating portion 11, the first connecting member 101 pushes the elastic arm 111 so that the elastic arm 111 undergoes a certain amount of deformation, and then the stop member 112 cooperates with the elastic arm 111 to apply a force to the elastic arm 111, which is beneficial to ensure that the first connecting member 101 is subjected to an appropriate amount of resistance during installation, thereby ensuring the installation feel of the first connecting member 101.

[0087] It is understandable that when the first connector 101 is separated from the terminal 100 , the interval between the stop member 112 and the elastic arm 111 can be specifically set according to actual needs.

[0088] Of course, the setting of the stop member 112 is not limited to this; in other embodiments, the stop member 112 can also be configured as follows: when the elastic arm 111 is separated from the first connecting member 101, the stop member 112 is in contact with the elastic arm 111.

[0089] In some embodiments, Figure 1-Figure 7 As shown, the terminal 100 is an integrally formed part, which is convenient for ensuring the structural strength and stability of the terminal 100 and convenient for processing. For example, the terminal 100 is formed by bending and stamping a metal part multiple times.

[0090] In some embodiments, the mating portion 11 is formed with a mating port 11a, the elastic arm 111 is cantilevered, and the elastic arm 111 has a fixed end A and a free end B, the fixed end A is arranged close to the mating port 11a relative to the free end B, then in a first direction, the fixed end A is located between the mating port 11a and the free end B; if the elastic arm 111 is arranged obliquely relative to the first direction, then along the mating direction of the first connector 101 (for example Figure 2 In the direction from front to back in the middle, the mating space provided for the first connector 101 by the side of the elastic arm 111 away from the stop portion 1121 can be gradually reduced, so that the elastic arm 111 can guide the first connector 101 to be quickly mated with the mating portion 11, thereby ensuring that the first connector 101 is quickly and accurately mated with the mating portion 11.

[0091] In other embodiments, Figure 2 , Figure 5 and Figure 7 As shown, the free end B is arranged near the mating port 11a relative to the fixed end A. Then, in the first direction, the free end B is located between the mating port 11a and the fixed end A, and the first connector 101 can also be smoothly mated with the mating portion 11 to be electrically connected to the elastic arm 111.

[0092] In some embodiments, Figure 2 , Figure 5 and Figure 7 As shown, the elastic arm 111 includes a first elastic section 1111 and a second elastic section 1112, and the elastic arm 111 has a contact portion 1110, and the contact portion 1110 is located at the connecting position of the first elastic section 1111 and the second elastic section 1112, and the first elastic section 1111 and the second elastic section 1112 are both inclined toward the side where the stop portion 1121 is located. Then, in a first direction, the first elastic section 1111 and the second elastic section 1112 are both inclined to extend, and the first elastic section 1111 and the second elastic section 1112 are respectively inclined to extend from the contact portion 1110 toward the side where the stop portion 1121 is located, so that the elastic arm 111 roughly forms a V-shaped structure, which facilitates the contact portion 1110 to form a transition portion, so as to prevent the contact portion 1110 from scratching the electroplating layer of the first connector 101 during the assembly process of the contact portion 1110 and the first connector 101.

[0093] For example, in Figure 2 and Figure 7In the example of , the first elastic segment 1111 and the second elastic segment 1112 both extend in the front-to-back direction, the stop portion 1121 is located on the upper side of the contact portion 1110, one of the first elastic segment 1111 and the second elastic segment 1112 extends backward and upward from the contact portion 1110, and the other extends forward and upward from the contact portion 1110. It can be understood that Figure 1 , Figure 2 and Figure 5-Figure 7 As shown, one end of the first elastic segment 1111 away from the second elastic segment 1112 is formed as a fixed end A, and one end of the second elastic segment 1112 away from the first elastic segment 1111 is formed as a free end B. At this time, the length of the first elastic segment 1111 may be greater than the length of the second elastic segment 1112; or, one end of the first elastic segment 1111 away from the second elastic segment 1112 is formed as a free end B, and one end of the second elastic segment 1112 away from the first elastic segment 1111 is formed with a fixed end A.

[0094] In some embodiments, Figure 1 , Figure 2 and Figure 5-Figure 7 As shown, the main body 1 includes a guide portion 12, which is arranged at the edge of the mating port 11a, and the guide portion 12 covers a part of the mating port 11a, so as to appropriately reduce the opening area of ​​the mating port 11a while ensuring that the mating port 11a allows the first connector 101 to be smoothly inserted, so that the mating port 11a has a certain guiding effect on the first connector 101, ensuring that the first connector 101 is smoothly mated to be electrically connected with the elastic arm 111; the guide portion 12 and the elastic arm 111 are arranged on the same side of the main body 1, and in the axial direction of the mating port 11a, the guide portion 12 blocks the adjacent mating of the elastic arm 111 At least a portion of one end of the mating opening 11a is overlapped with at least a portion of the projection of the guide portion 12 along the axial direction of the mating opening 11a and the projection of the above-mentioned one end of the elastic arm 111 along the axial direction of the mating opening 11a, so that when the first connector 101 is electrically connected to the terminal 100 through the mating opening 11a, the first connector 101 is prevented from moving toward the above-mentioned one end of the elastic arm 111 to cause damage between the first connector 101 and the elastic arm 111 (for example, the fixed end A, or the free end B, etc.), so as to protect the first connector 101 and the elastic arm 111, and protect the elastic arm 111 from being damaged by the first connector 101.

[0095] It can be understood that when the fixed end A is arranged close to the mating port 11a relative to the free end B, the guide portion 12 blocks at least a portion of the fixed end A to avoid damage to the first connector 101 and the fixed end A when the first connector 101 is electrically connected to the terminal 100 from the mating port 11a; when the free end B is arranged close to the mating port 11a relative to the fixed end A, the guide portion 12 blocks at least a portion of the free end B to avoid damage to the first connector 101 and the free end B when the first connector 101 is electrically connected to the terminal 100 from the mating port 11a.

[0096] In some embodiments, Figure 1 , Figure 2 and Figure 5-Figure 7 As shown, the guide portion 12 extends in a direction perpendicular to the axial direction of the mating opening 11 a , so the guide portion 12 has a simple structure and is easy to process.

[0097] In other embodiments, the guide portion 12 is tilted toward the elastic arm 111 in a direction perpendicular to the axial direction of the mating port 11a, so that the guide portion 12 can appropriately reduce the opening size of the mating port 11a, thereby facilitating the mating port 11a to guide the first connector 101 to be electrically connected to the terminal 100 through the mating port 11a, thereby facilitating user operation.

[0098] The guide portion 12 is tilted toward the elastic arm 111 , for example, the guide portion 12 is tilted toward the elastic arm 111 along a straight line, or the guide portion 12 is tilted toward the elastic arm 111 along a curve.

[0099] In some embodiments, Figure 1-Figure 7As shown, the mating portion 11 defines a mating cavity 110 in communication with the mating port 11a, the mating cavity 110 is suitable for mating with the first connector 101, the mating cavity 110 can extend along a first direction, and the plurality of cavity walls of the mating cavity 110 include a first cavity wall 1101, a second cavity wall 1102, and two connecting side walls 1103, the first cavity wall 1101 and the second cavity wall 1102 are spaced apart along a third direction, and the two connecting side walls 1103 are respectively arranged at the opposite ends of the second cavity wall 1102 in the second direction. On both sides, the first cavity wall 1101 includes a first top wall 1101a and a second top wall 1101b, the first top wall 1101a is arranged on the side of the second top wall 1101b facing away from the second cavity wall 1102, one connecting side wall 1103 is connected between the first top wall 1101a and the second cavity wall 1102, and the other connecting side wall 1103 is connected between the second top wall 1101b and the second cavity wall 1102, and the second direction, the third direction and the length direction of the main body 1 are perpendicular to each other. Among them, the elastic arm 111 is arranged on the second top wall 1101b, and the stop portion 1121 is located on the side of the elastic arm 111 facing the first top wall 1101a, then the elastic arm 111 is arranged in the mating cavity 110, and the stop portion 1121 extends into the mating cavity 110. Therefore, the multiple cavity walls of the mating cavity 110 can play a certain protective role on the elastic arm 111 and the stop portion 1121, further ensuring the reliable connection between the elastic arm 111 and the first connecting member 101, and facilitating the molding of the mating portion 11.

[0100] For example, the multiple cavity walls of the mating cavity 110 are integrally formed by bending a metal piece multiple times. Figure 1-Figure 7 As shown, the terminal 100 includes a second cavity wall 1102, two connecting side walls 1103 are bent upward and extend from the left and right sides of the second cavity wall 1102, respectively, a first top wall 1101a extends from the upper end of the left connecting side wall 1103 toward the right connecting side wall 1103, and a second top wall 1101b extends from the upper end of the right connecting side wall 1103 toward the left connecting side wall 1103, and the first top wall 1101a and the second top wall 1101b are stacked in parallel. When a guide portion 12 is provided at the edge of the mating port 11a, the guide portion 12 extends from an end of the first top wall 1101a corresponding to the mating port 11a toward the second cavity wall 1102 to cover a portion of the mating port 11a.

[0101] Optionally, in Figure 2-Figure 4 and Figure 7 In the example, the stop member 112 is configured as follows: when the contact portion 1110 is separated from the first connecting member 101, the stop portion 1121 is spaced apart from the first cavity wall 1101 in the third direction, so that the stop portion 1121 applies a force to the elastic arm 111 through the elastic deformation of the stop member 112.

[0102] In some embodiments, Figure 1 , Figure 5 and Figure 6 As shown, the main body 1 also includes a crimping portion 13, which is used to electrically connect with the second connector. The crimping portion 13 and the elastic arm 111 are arranged in sequence along the length direction of the main body 1. The crimping portion 13 includes a conductor crimping portion 131 and an insulating crimping portion 132. The conductor crimping portion 131 and the insulating crimping portion 132 are arranged in sequence along the length direction of the main body 1, and the conductor crimping portion 131 is located between the mating cavity 110 and the insulating crimping portion 132. The conductor crimping portion 131 is used to fix and electrically connect the exposed conductor portion of the second connector (for example, the front end of the conductor with the insulation skin stripped off the wire), and the insulating crimping portion 132 is used to fix the portion of the second connector with an insulating layer (for example, the rear insulating portion of the wire wrapped with insulation skin) to keep the second connector fixed, so that the connection between the second connector and the crimping portion 13 is stable and reliable.

[0103] It can be seen that the main body 1 is used to electrically connect the first connecting member 101 and the second connecting member.

[0104] For example, in Figure 1 , Figure 5 and Figure 6 In the example, the crimping portion 13 is formed with a mounting groove, the mounting groove is used to accommodate the second connector, the conductor crimping portion 131 and the insulation crimping portion 132 are both roughly formed into a V-shaped structure, and the conductor crimping portion 131 and the insulation crimping portion 132 are both used to press the second connector onto the bottom wall of the mounting groove to ensure the electrical connection between the main body 1 and the second connector, thereby ensuring the relative fixation of the main body 1 and the second connector. The bottom wall of the mounting groove can be connected to a side cavity wall of the mating cavity 110, such as the second cavity wall 1102.

[0105] The electrical connector according to the second embodiment of the present invention comprises: a housing and a terminal 100 . The terminal 100 is the terminal 100 according to the first embodiment of the present invention, and the terminal 100 is fixedly matched with the housing.

[0106] For example, a mounting hole is defined in the shell, a through opening is formed on the peripheral wall of the mounting hole, a movable block is provided at the through opening, a slot 100a is formed on the terminal 100, the terminal 100 is plugged into the mounting hole, and the slot 100a is arranged opposite to the through opening. At this time, the block is matched with the through opening so that the block and the slot 100a are limitedly matched along a first direction to limit the axial displacement of the terminal 100 in the shell along the mounting hole to prevent the terminal 100 from detaching from the shell, thereby ensuring stable fit between the terminal 100 and the shell; if the terminal 100 needs to be separated from the shell, the block can be removed from the through opening first to release the restriction on the terminal 100, so that the terminal 100 can detach from the shell along the axial direction of the mounting hole.

[0107] Optionally, a side of the mating portion 11 away from the mating opening 11a can be used to form a card slot 100a, so that when the terminal 100 is mated in the mounting hole, the card block can stop at the end of the mating portion 11 away from the mating opening 11a to limit the terminal 100.

[0108] For example, a buckle is formed on the shell, and a baffle 14 is formed on the first top wall 1101a. The baffle 14 is inclined relative to the first direction and is cantilevered. The baffle 14 cooperates with the buckle to limit the terminal 100 and the shell in the first direction, preventing the terminal 100 from escaping from the shell, thereby ensuring the stable fit between the terminal 100 and the shell. During the installation of the terminal 100 in the shell, the baffle 14 is compressed and deformed to deflect toward the mating part 11, until the terminal 100 is installed in place, and the baffle 14 returns to its initial state and stops against the buckle.

[0109] According to the electrical connector of the embodiment of the present invention, by adopting the above-mentioned terminal 100, the stability and reliability of the electrical connection of the electrical connector can be improved to meet the use requirements of complex working conditions.

[0110] The wiring harness according to the third embodiment of the present invention comprises an electrical connector and electric wires. The electrical connector is the electrical connector according to the second embodiment of the present invention. The electric wires are electrically connected to the terminals 100 .

[0111] The terminal 100 is used to electrically connect the first connector 101 and the second connector, and the wire is one of the first connector 101 and the second connector.

[0112] For example, the first connection member 101 may be a lug of the male terminal 100 , the terminal 100 may be a female terminal 100 , and the second connection member may be an electric wire.

[0113] The wire harness according to the embodiment of the present invention can ensure stable and reliable connection of the wire harness by adopting the above-mentioned electrical connector.

[0114] A vehicle according to an embodiment of a fourth aspect of the present invention comprises a wiring harness according to an embodiment of the third aspect of the present invention.

[0115] The vehicle according to the embodiment of the present invention adopts the above-mentioned wiring harness to ensure reliable electrical connection between components, so as to ensure the driving safety of the vehicle, especially the driving safety in complex environments.
