[0020] The following will disclose multiple embodiments of the present application with diagrams. For the sake of clear illustration, many implementation details will be described together in the following narrative. However, it should be understood that these implementation details are not used to limit the present application. That is to say, in some embodiments of the present application, these implementation details are unnecessary. In addition, to simplify the diagrams, some conventional structures and components will be shown in a simple schematic manner in the diagrams. In the following embodiments, the same reference numerals will be used to denote the same or similar components.

[0021] Please refer to Figure 1 and Figure 2 , which are the perspective views and another perspective view of the electrical connector of the present application. As shown in the figure, this embodiment provides an electrical connector 1, and the electrical connector 1 includes a housing 11 and a terminal member 13. The terminal member 13 is assembled in the housing 11. The terminal member 13 includes a first terminal 131 and a second terminal 132 opposite to the first terminal 131. The first terminal 131 has a first convex portion 1311 and a first notch portion 1312, and the first convex portion 1311 is located on one side of the first notch portion 1312. The second terminal 132 has a second convex portion 1321 and a second notch portion 1322, and the second convex portion 1321 is located on one side of the second notch portion 1322. The first convex portion 1311 is opposite to the second notch portion 1322, and the second convex portion 1321 is opposite to the first notch portion 1312.

[0022] As described above, the geometric shape of the first convex portion 1311 and the notch shape of the second notch portion 1322 are complementary structures, and the geometric shape of the second convex portion 1321 and the notch shape of the first notch portion 1312 are complementary structures. When one end of the first terminal 131 having the first convex portion 1311 and the first notch portion 1312 and one end of the second terminal 132 having the second convex portion 1321 and the second notch portion 1322 approach each other, the first convex portion 1311 is located in the second notch portion 1322, and the second convex portion 1321 is located in the first notch portion 1312, so that one end of the first terminal 131 and one end of the second terminal 132 can be prevented from interfering with each other. The geometric shape of the convex portion in this embodiment is not limited, and the convex portion can be a geometric shape such as a circle, a triangle or a rectangle, and the notch shape of the notch portion corresponds to the geometric shape of the convex portion, and the notch portion is also a corresponding notch shape such as a circle, a triangle or a rectangle.

[0023] In addition, the convex portion and the notch portion may also be non-complementary structures. In this embodiment, the notch shape of the second notch portion 1322 can accommodate the geometric shape of the first convex portion 1311, and the notch shape of the first notch portion 1312 can accommodate the geometric shape of the second convex portion 1321. The above method can also avoid the problem that one end of the first terminal 131 and one end of the second terminal 132 interfere with each other. In this embodiment, the first terminal 131 and the second terminal 132 are two relatively arranged terminals, and the first terminal 131 and the second terminal 132 are respectively assembled in the housing 11. In addition, the terminal member 13 of the present application may also include a terminal body (not shown in the figure). The first terminal 131 and the second terminal 132 extend from one side of the terminal body respectively. The terminal body, the first terminal 131 and the second terminal 132 are integrally formed structures, that is, one terminal, so as to further reduce the volume occupied by the terminal member 13. The terminal member 13 of the present application can be improved according to the needs of users and implemented by applying the corresponding structure of the convex portion and the notch portion of the relative terminals.

[0024] Furthermore, please refer to Figure 3 together, which is an exploded view of the electrical connector of the present application. As shown in the figure, in this embodiment, the first terminal 131 and the second terminal 132 are respectively assembled in the housing 11 for illustration. The first terminal 131 has a plurality of first elastic pieces 1310. One end of each first elastic piece 1310 has a first convex portion 1311 and a first notch portion 1312.

The first terminal 131 has a first guiding portion 1313, and the second terminal 132 has a second guiding portion 1323. The first guiding portion 1313 of the first terminal 131 is assembled into the housing 11 along the corresponding guiding groove 110, such that the first terminal 131 is disposed parallel to the first inner wall 111. The second guiding portion 1323 of the second terminal 132 is assembled into the housing 11 along the corresponding guiding groove 110, such that the second terminal 132 is disposed parallel to the second inner wall 112, and the first terminal 131 and the second terminal 132 are disposed opposite to each other.

[0027] As described above, the notch of the guiding groove 110 has a guiding bevel 1101. The first guiding portion 1313 of the first terminal 131 and the second guiding portion 1323 of the second terminal 132 are assembled into the guiding groove 110 through the guiding bevel 1101.

As shown in the figure, the present embodiment provides a docking electrical connector 2, which includes a docking housing 21 and a terminal assembly 23. The terminal assembly 23 is assembled within the docking housing 21. The terminal assembly 23 includes a first terminal 231 and a second terminal 232 disposed opposite to the first terminal 231. The opposing surfaces of the first terminal 231 and the second terminal 232 are both anti-friction surfaces 2301. The anti-friction surfaces 2301 are used to protect against frictional damage to the electrical contact surfaces of the first terminal 231 and the second terminal 232. When the electrical connector 1 is plugged into the docking electrical connector 2, the terminal member 13 of the electrical connector 1 will abut against the anti-friction surface 2301 outside the electrical contact surface of the terminal assembly 23 of the docking electrical connector 2. Thus, in addition to being used for electrical connection, the anti-friction surface 2301 can also reduce the frictional loss when the terminal member 13 of the electrical connector 1 is plugged into the terminal assembly 23 of the docking electrical connector 2. The anti-friction surface 2301 can be a gold-plated surface, a silver-plated surface, a copper-plated surface, etc.

[0031] In this embodiment, the anti-friction surfaces 2301 of the first terminal 231 or the second terminal 232 are only provided on one of the side surfaces. Therefore, a structure for preventing the first terminal 231 and the second terminal 232 from being assembled in the opposite direction is further provided in the docking housing 21 to avoid assembly errors. The docking housing 21 has a first inner wall 211, a second inner wall 212 and two inner side walls 213. The first inner wall 211 and the second inner wall 212 are opposite to each other. The two inner side walls 213 are respectively connected to the sides of the first inner wall 211 and the second inner wall 212. The docking housing 21 also has two bumps 214. The two bumps 214 are respectively provided on the first inner wall 211 and the second inner wall 212, and the two bumps 214 are located at diagonally opposite positions. Both the first terminal 231 and the second terminal 232 have notch portions 2302. The first terminal 231 and the second terminal 232 are assembled in the docking housing 21. The two notch portions 2302 and the two bumps 214 are engaged with each other. In this way, the anti-friction surface 2301 of the first terminal 231 is provided on the side away from the first inner wall 211 of the docking housing 21, and the anti-friction surface 2301 of the second terminal 232 is provided on the side away from the second inner wall 212 of the docking housing 21, so that the relative surfaces of the first terminal 231 and the second terminal 232 are the anti-friction surfaces 2301. In this application, the bumps 214 can surely face the anti-friction surface 2301 of the first terminal 231 and the anti-friction surface 2301 of the second terminal 232 to each other in the insertion space of the docking housing 21.

[0032] In addition, interference portions 2303 are provided on both sides of the first terminal 231 and the second terminal 232. The first terminal 231 and the second terminal 232 are assembled in the docking housing 21, and the interference portions 2303 abut against the two inner side walls 213. In this way, the first terminal 231 and the second terminal 232 can be fixed in the docking housing 21.

[0033] Please refer to Figures 8 to 10 , Figure 8 which is the exploded view of the connection between the electrical connector and the docking electrical connector of this application, Figure 9 which is the perspective view of the electrical connector assembly of this application and Figure 10 which is Figure 9 the cross-sectional view taken along the line B-B' of

[0034] As described above, the housing 11 of the electrical connector 1 further includes a plugging guiding groove 10, and the docking housing 21 of the docking electrical connector 2 includes a plugging guiding block 20. The plugging guiding block 20 is plugged into the plugging guiding groove 10, enabling the electrical connector 1 to be smoothly plugged into the docking electrical connector 2.

[0035] In this embodiment, the docking electrical connector 2 and the electrical connector 1 are plugged together to form an electrical connector assembly 3. The terminal member 13 of the electrical connector 1 is plugged into the terminal assembly 23 of the docking electrical connector 2, that is, the terminal member 13 of the electrical connector 1 is located between the terminal assemblies 23 of the docking electrical connector 2. Among them, the first elastic piece 1310 of the first terminal 131 of the terminal member 13 abuts against the anti-friction surface 2301 of the first terminal 231 of the terminal assembly 23. The second elastic piece 1320 of the second terminal 132 of the terminal member 13 abuts against the anti-friction surface 2301 of the second terminal 232 of the terminal assembly 23.

[0036] As described above, the first elastic piece 1310 is squeezed by the first terminal 231, and the second elastic piece 1320 is squeezed by the second terminal 232, causing one end of the first elastic piece 1310 and one end of the second elastic piece 1320 to bend inward, and one end of the first elastic piece 1310 and one end of the second elastic piece 1320 to intersect with each other. Among them, the first convex portion 1311 of the bent first elastic piece 1310 is located in the second notch portion 1322 of the second elastic piece 1320, and the second convex portion 1321 of the bent second elastic piece 1320 is located in the first notch portion 1312 of the first elastic piece 1310. Through the correspondence between the convex portion and the notch portion, the electrical connector assembly 3 of this embodiment can avoid the problem that the first elastic piece 1310 and the second elastic piece 1320 interfere with each other and cause deformation of the first elastic piece 1310 and the second elastic piece 1320.
