[0031] Specifically, as Figure 1 、 Figure 2 and Figure 4 shown, the boss 113 has thermoplasticity to expand the part that passes through the positioning hole 126 and fix the female terminal 12 in the accommodation cavity 111.

[0032] The present disclosure does not limit the mating shape of the positioning hole 126 and the boss 113.

The two male terminals 22 are inserted into the socket rubber core 21 and are integrally formed with the socket rubber core 21. Each of the two male terminals 22 has one end exposed in the plug rubber core 21 and the other end placed in the accommodating chamber 212 and docked with the female terminal 12.

[0033] In one embodiment of the present disclosure, Figure 1 As shown, the female terminal 12 further includes two clamping portions 121 connected to the supporting portion 123 , and the two clamping portions 121 are located on the same side of the supporting portion 123 .

[0034] Specifically, if Figure 1 As shown, each of the two clamping parts 121 includes a first support arm, a first elastic arm, a second support arm and a second elastic arm; the first support arm is fixed to the support part 123 and extends perpendicular to the support part 123, the second support arm and the first support arm are arranged opposite to each other, and the second support arm is fixed to the support part 123 and extends perpendicular to the support part 123; the first support arm and the second support arm cooperate with the inner wall of the accommodating cavity 111 to limit the rotation of the female terminal 12 in the plug rubber core 11, and at the same time provide a guiding effect for the installation of the female terminal 12, reducing the difficulty of installation and improving the reliability of the female terminal assembly 2, the first elastic arm is connected to the first support arm, the second elastic arm is connected to the second support arm, the first elastic arm and the second elastic arm are arranged opposite to each other and extend toward each other for clamping one of the two male terminals.

[0035] Specifically, if Figure 2 、 Figure 3 As shown, there is a first bending portion 1241 between the two ends of the first elastic arm, which protrudes toward the direction where the second elastic arm is located; there is a second bending portion 1242 between the two ends of the second elastic arm, which protrudes toward the direction where the first elastic arm is located, and the first bending portion 1241 faces the second bending portion 1242.

[0036] Specifically, if Figure 2 、 Figure 3As shown, the first elastic arm gradually approaches the second elastic arm from the end far away from the support portion 123 to the first bending portion 1241, forming a first guiding portion 1251; the second elastic arm gradually approaches the first elastic arm from the end far away from the support portion 123 to the second bending portion 1242, forming a second guiding portion 1252.

[0037] In an embodiment of the present disclosure, as Figure 2 , Figure 3 shown, each of the two male terminals 22 has a first guiding angle 221 near the first end of the first elastic arm; each of the two male terminals 22 has a second guiding angle 222 near one end of the second elastic arm; the first guiding angle 221 cooperates with the first guiding portion 1251, and the second guiding angle 222 cooperates with the second guiding portion 1252 to guide the docking of the two male terminals 22 with the female terminal 12, and the first bending portion 1241 and the second bending portion 1242 contact the two male terminals 22 and form an electrical connection.

[0038] Specifically, the first guiding angle 221 and the second guiding angle 222 cooperate to form a guiding port. During the docking process of the male terminal 22 and the female terminal 12, the first end of the male terminal 22 extends into the guiding port, the first guiding angle 221 cooperates with the first guiding portion 1251, and the second guiding angle 222 cooperates with the second guiding portion 1252, so that the male terminal 12 accurately docks with the clamping portion 121, reducing the mechanical stress and loss during the docking process of the male terminal 22 and the female terminal 12, optimizing the assembly efficiency, and at the same time offsetting the product manufacturing error and the fitting gap between the interlocking female terminal assembly 1 and the interlocking male terminal assembly 2, improving the reliability of the product. After the male terminal 22 is inserted in place, due to the self-elasticity of the elastic arm of the clamping portion 121, the first folding portion 1241 and the second bending portion 1242 tightly clamp the surface of the male terminal 22 to prevent the male terminal 22 from being disturbed and loosened or detached, ensuring the stability of the electrical connection.

The end of the male terminal 22 close to the first elastic arm is placed in the accommodating chamber 212, and the female terminal 12 is plugged into the male terminal 22 through the clamping portion 121. The first end of the male terminal 22 is relatively arranged at the guide port formed by the first guide angle 221 and the second guide angle 222, away from the shell of the plug rubber core 11, to prevent the male terminal 22 from colliding and deforming with the plug rubber core 11 during the docking process, thereby improving the safety of the docking process.

[0042] The present disclosure does not limit the number and shape of the first positioning grooves 112. In one embodiment of the present disclosure, Figure 1 As shown, the first support arm and the second support arm are connected by a partition perpendicular to the support portion 123, and the partition and the first support arm and the second support arm form a second positioning groove 122, and the second positioning groove 122 cooperates with the first positioning groove 112, and the notch of the second positioning groove 122 is larger than the notch of the first positioning groove 112, so that the female terminal assembly 1 is guided to dock with the two positioning platforms 211 set on the side wall of the accommodating chamber 212 through the two first positioning grooves 112 set opposite to each other on the side wall, and the plug rubber core 11 contacts the socket rubber core 21 first, and the female terminal 12 contacts the male terminal 22 later, which reduces the difficulty of assembly and improves the docking accuracy.
