In the illustrated embodiment of the present invention, the first docking portion 12a and the second docking portion 12b are of different sizes.

[0076] In the illustrated embodiment of the present invention, in order to improve heat dissipation, the insulating body 1 further includes a heat dissipation channel 13 penetrating through the insulating body 1 in the vertical direction and located beside the first docking portion 12a and / or the second docking portion 12b.

Those skilled in the art can understand that the first docking portion 12a and its corresponding structure are applicable to the second docking portion 12b, and the first conductive terminal 2a and its corresponding structure are applicable to the second conductive terminal 2b.

[0081] Please refer to Figures 12 to 14 As shown, the electrical connector 100 further includes an elastic clamping arm 14. The elastic clamping arm 14 protrudes from the first surface 1111 of the substrate 111 into the receiving space 10, and the elastic clamping arm 14 is located on the outer peripheral side of the assembly hole 1113.

[0082] In the illustrated embodiment of the present invention, the elastic clamping arm 14 is integrally formed with the insulating body 1. Of course, in other embodiments, the elastic clamping arm 14 can also be separately provided from the insulating body 1 and then assembled and fixed to the insulating body 1.

[0083] Please refer to Figure 13 and Figure 14As shown, the elastic clamping arm 14 is cylindrical and includes an internal space 140. Specifically, the insulating body 1 includes a cylindrical portion 114 integrally formed with the substrate 111, and the cylindrical portion 114 is provided with an opening 114a penetrating upward through the cylindrical portion 114. The internal space 140 is formed within the cylindrical portion 114 and communicates with the opening 114a. The cylindrical portion 114 is provided with a slot 1141 to form the elastic clamping arm 14 in a cantilever shape. The elastic clamping arms 14 are several in number and are arranged at intervals along the circumferential direction of the cylindrical portion 114. In the illustrated embodiment of the present invention, each elastic clamping arm 14 is in a cantilever shape to have better elasticity, so as to facilitate necessary elastic deformation when assembling the conductive terminal 2 along the installation direction (for example, from bottom to top).

[0084] In the illustrated embodiment of the present invention, the elastic clamping arm 14 includes a guiding portion 141 at the top, and the guiding portion 141 is provided with a first guiding inclined surface 1411 exposed within the internal space 140 and inclined along the installation direction. In addition, the guiding portion 141 is further provided with an upper surface 1412 exposed within the receiving space 10.

[0085] In the illustrated embodiment of the present invention, the assembly hole 1113 includes a first assembly hole 1113a with a smaller diameter, and a second assembly hole 1113b located at the bottom of the first assembly hole 1113a and communicating with the first assembly hole 1113a. The substrate 111 includes a step surface 1113c formed between the first assembly hole 1113a and the second assembly hole 1113b.

[0086] Please refer to Figures 7 to 10 As shown, the conductive terminal 2 includes a mounting portion 21, a contact portion 22 extending from one end (for example, the top end) of the mounting portion 21, and a tail portion 23 extending from the other end (for example, the bottom end) of the mounting portion 21. In the illustrated embodiment of the present invention, the contact portion 22, the mounting portion 21, and the tail portion 23 are all cylindrical respectively to be able to better transmit electricity.

[0087] In the illustrated embodiment of the present invention, the upper part of the mounting portion 21 is provided with a protruding portion 211, the lower part of the mounting portion 21 is provided with an abutting protrusion 212, and the bottom surface of the mounting portion 21 is provided with a welding surface 213 configured to perform surface welding with the welding pad 304 of the circuit board 300. The tail portion 23 is configured to be inserted into the mounting hole 305 of the circuit board 300 (as Figure 13 shown).

[0088] In the illustrated embodiment of the present invention, the protruding portion 211 is provided with a second guiding inclined surface 2111 and a lower surface 2112.

[0089] Please refer to Figure 13 As shown, in the illustrated embodiment of the present invention, the mounting portion 21 includes a main body portion 210a, a tapered transition portion 210b connected to the main body portion 210a and located at the upper end of the main body portion 210a, and a mating portion 210c connected to the tapered transition portion 210b and located at the upper end of the tapered transition portion 210b. The protruding portion 211 is connected to the mating portion 210c and located at the upper end of the mating portion 210c, and the abutting protrusion 212 is connected to the main body portion 210a and located at the lower end of the main body portion 210a.

[0090] In the illustrated embodiment of the present invention, the diameter D1 of the contact portion 22 is smaller than the diameter D2 of the main body portion 210a, and the diameter D1 of the contact portion 22 is smaller than the diameter of the opening 114a; the diameter of the protruding portion 211 is greater than the diameter of the opening 114a. With such a setting, when the conductive terminal 2 passes through the opening 114a along the installation direction, the contact portion 22 with a relatively small diameter can more easily pass through the opening 114a, thereby improving the assembly efficiency. Preferably, the contact portion 22 is provided with a guiding portion 221 located at its top and in a contracted shape to more facilitate passing the contact portion 22 through the opening 114a.

[0091] The conductive terminal 2 is assembled to the insulating body 1 along the installation direction. At least part of the mounting portion 21 of the conductive terminal 2 is located in the assembly hole 1113. The contact portion 22 and the protruding portion 211 of the conductive terminal 21 pass through the elastic clamping arms 14 to extend into the receiving space 10, and at least part of the tail portion 23 protrudes from the second surface 1112; the elastic clamping arms 14 are configured to abut against the protruding portion 211 in a direction opposite to the installation direction (for example, from top to bottom) to prevent the conductive terminal 2 from detaching from the elastic clamping arms 14.

[0092] Specifically, when the conductive terminal 2 is assembled to the insulating body 1 along the installation direction, the second guiding inclined surface 2111 slides on the first guiding inclined surface 1411 to outwardly expand the elastic clamping arms 14, so that the protruding portion 211 can pass through the internal space 140 and the opening 114a.

[0093] After the protruding portion 211 passes through the internal space 140, the upper surface 1412 of the guiding portion 141 can abut against the lower surface 2112 of the protruding portion 211 to prevent the conductive terminal 2 from detaching from the elastic clamping arms 14.

[0094] The conductive terminal 2 includes a limiting portion configured to abut against the elastic clamping arm 14 and / or the insulating body 1 to prevent the conductive terminal 2 from being over-assembled along the installation direction, that is, to prevent the conductive terminal 2 from being over-inserted into the insulating body 1 along the installation direction.

[0095] In the illustrated embodiment of the present invention, the limiting portion is the abutting protrusion 212, and at least a part of the abutting protrusion 212 is received in the second assembly hole 1113b. The stepped surface 1113c can abut against the abutting protrusion 212 to prevent the conductive terminal 2 from being over-inserted into the insulating body 1 along the installation direction.

[0096] In the illustrated embodiment of the present invention, the conductive terminal 2 can float along a first direction A1-A1 (such as the vertical direction) and a second direction A2-A2 perpendicular to the first direction A1-A1 (such as the horizontal direction) to adjust the up-and-down and left-and-right positions of the conductive terminal 2, so that the welding surface 213 of the conductive terminal 2 can be attached to the circuit board 300 for surface soldering, and the tail portion 23 can be inserted into the mounting hole 305 of the circuit board 300.

[0097] Those skilled in the art can understand that when the conductive terminal 2 is installed on the insulating body 1 and the elastic clamping arm 14, there is a reasonably large gap at the joint of the conductive terminal 2, the insulating body 1 and the elastic clamping arm 14. Thus, under the action of the self-gravity of the conductive terminal 2, the conductive terminal 2 can adaptively adjust its position along the first direction A1-A1. In addition, due to this reasonably large gap, the conductive terminal 2 can perform position adjustment within a certain range along the second direction A2-A2, which is beneficial to inserting the tail portion 23 of the conductive terminal 2 into the mounting hole 305 of the circuit board 300.

[0098] Please refer to Figure 15 and Figure 16 As shown, the docking connector 200 includes a docking insulating body 4, a plurality of docking conductive terminals 5 installed in the docking insulating body 4, and a fastening member 6 locked to the docking insulating body 4. In the illustrated embodiment of the present invention, the docking insulating body 4 includes a docking base 41 and a plurality of docking posts 42 protruding from the docking base 41. The docking conductive terminal 5 includes a plugging portion 51 received in the docking post 42, and the plugging portion 51 is provided with a receiving groove 511. The fastening member 6 includes a plurality of fastening arms 61 fastened to the docking base 41 described above.

[0099] When the electrical connector 100 is docked with the docking connector 200, the docking stud 42 is inserted into the receiving space 10, and the contact portion 22 of the conductive terminal 2 is inserted into the receiving groove 511 of the docking conductive terminal 5 to achieve conduction between the two.

[0100] Please refer to Figure 12 and Figure 13 As shown, when the electrical connector 100 is installed on the circuit board 300 and is installed in place, there is a gap G between the first surface 301 of the circuit board 300 and the second surface 1112 of the substrate 111. The gap G is connected to the heat dissipation channel 13, which is conducive to timely and effective heat dissipation and prevents problems such as overheating.

[0101] Compared with the prior art, the conductive terminal 2 of the present invention can float along the first direction A1-A1 and the second direction A2-A2 perpendicular to the first direction A1-A1 to adjust the position of the conductive terminal 2, so that the welding surface 213 of the conductive terminal 2 can fit the circuit board 300, and the tail 23 can be inserted into the mounting hole 305 of the circuit board 300; this setting is conducive to adjusting the conductive terminal 2 and improves the installation convenience when the electrical connector 100 is installed on the circuit board 300.

[0102] The above embodiments are only used to illustrate the present invention and do not limit the technical solutions described in the present invention. The understanding of the present invention should be based on those skilled in the art of the relevant technical field. Although this specification has described the present invention in detail with reference to the above embodiments, those of ordinary skill in the art should understand that those skilled in the relevant technical field can still modify the present invention or make equivalent replacements, and all technical solutions and their improvements that do not depart from the spirit and scope of the present invention should be covered within the scope of the claims of the present invention.
