[0024] The present invention will be described in detail below in conjunction with the embodiments shown in the accompanying drawings. However, the embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on the embodiments are all within the protection scope of the present invention.

[0025] Please refer to Figures 1 to 7 The figure shows a preferred embodiment of the electrical connector 100 of the present invention. The electrical connector 100 comprises an insulating body 1 , a plurality of conductive terminals 2 assembled in the insulating body 1 , and a locking member 3 installed in the insulating body 1 .

[0026] Please refer to Figures 1 to 5 As shown, the insulating body 1 has a base 11 and a mounting portion 12 located at the rear side of the base. The mounting portion 12 has a pair of notches 121 located at both sides thereof in the transverse direction. The notches 121 are formed by being recessed forward from the rear end surface of the mounting portion 12 .

[0027] Please refer to Figures 2 to 5 As shown, the conductive terminal 2 includes first terminals 2a and second terminals 2b whose contact portions 201 are arranged in two rows in the height direction, and the contact portions 201 of the first and second terminals 2a, 2b are arranged in opposite directions.

[0028] In the embodiment shown in the present invention, the first terminal 2a and the second terminal 2b arranged opposite to it in the height direction are arranged independently of each other. In other embodiments of the present invention, the first terminal 2a and the second terminal 2b arranged opposite to it in the height direction are connected as a whole to form a conjoined terminal. Specifically, in the present invention, the positions of the contact portions 201 of the two rows of conductive terminals on the insulating body 1 are the same as the positions of the docking portions of the corresponding terminals on the standard USB Type-C plug connector.

[0029] Please refer to Figures 1 to 7 As shown, the locking member 3 includes a fixing portion 31, a locking arm 32 extending forward from the fixing portion 31, and a pair of soldering feet 33 extending backward from the fixing portion 31 for soldering to different sides of a circuit board (not shown).

[0030] The locking member 3 also has a pair of extension arms 34 extending backward from the fixing portion 31, and the pair of extension arms 34 are located on the outside of the welding foot 33 in the lateral direction, and each of the extension arms 34 and the welding foot 33 on the same side are spaced apart in the lateral direction. In this way, by arranging the extension arms 34 located on the outside and spaced apart from the welding foot 33, the locking member 3 is prevented from being deflected when inserted into the insulating body 1, and at the same time, the locking member 3 can be ensured to be subjected to balanced force.

[0031] In the present invention, the fixing portion 31 extends in the lateral direction as a whole, and the fixing portion 31 is provided with a first groove 311 formed by being recessed backward from the front surface thereof, and the first groove 311 is in a narrow and long shape extending in the lateral direction. In some embodiments of the present invention, the fixing portion 31 is covered with an insulating block (not shown) to avoid the risk of overlap between the locking member 3 and the power terminal, and in other embodiments, the fixing portion 31 may not be provided with an insulating block.

[0032] The fixing portion 31 further has a pair of second grooves 312 disposed on both sides of the first groove 311 in the transverse direction. The second grooves 312 are located at the junction of the fixing portion 31 and the locking arm 32 .

[0033] The fixing portion 31 further has a pair of third grooves 313 recessed forward from its rear end surface. The third grooves 313 are disposed on both sides of the first groove 312 in the transverse direction and are located between the pair of second grooves 312 .

[0034] The pair of welding legs 33 are disposed at both sides of the fixing portion 31 in the height direction, and the welding legs 33 extend backward beyond the rear end surface of the extension arm 34 , while the extension arm 34 does not extend backward beyond the rear end surface of the insulating body 1 .

[0035] Specifically, if Figure 6 As shown, the width of the extension arm 34 in the transverse direction is smaller than the width of the welding foot 33 in the transverse direction. Further preferably, in this embodiment, the width of the interval between the extension arm 34 and the welding foot 33 on the same side in the transverse direction is larger than the width of each extension arm 34 in the transverse direction, and smaller than the width of each welding foot 33 in the transverse direction, thereby ensuring the structural strength of the welding foot 33, and at the same time using the outer extension arm 34 to ensure the balance of the locking member 3 during insertion, to avoid spinning during insertion.

[0036] In the present invention, the notch 121 is formed by being recessed forward from the rear end surface of the mounting portion 12 to accommodate the extension arm 34 and the welding foot 33 on the same side, and the notch 121 is open outward along the lateral direction to provide a clearance space for the side of the locking member 3 during installation.

[0037] The mounting portion 12 also has a mounting space 120 formed by being recessed forward from the rear end thereof, and the mounting space 120 includes a first mounting area 1201 and a second mounting area 1202 connected front to back, and the first and second mounting areas 1201 and 1202 have different heights in the height direction to form a step surface 1203 therebetween, and the fixing portion 31 is accommodated in the first mounting area 1201, and the soldering foot 33 is accommodated in the second mounting area 1202. The height of the first mounting area 1201 in the height direction is smaller than the height of the second mounting area 1202 in the height direction, and a part of the soldering foot 33 is accommodated in the second mounting area 1202, and another part protrudes from the rear side of the mounting portion 12, so that the fixing portion 31 is reliably limited in the first mounting area 1201, and the circuit board inserted forward can be accommodated in the second mounting area 1202.

[0038] Furthermore, in some embodiments of the present invention, the electrical connector 100 also has a shielding shell 4 that is sleeved outside the insulating body 1, and the extension arm 34 and the welding foot 33 are accommodated and limited between the inner wall surface 41 of the shielding shell 4 and the side wall surface 123 at the rear of the insulating body 1.

[0039] The electrical connector 100 of the present invention provides a pair of extension arms 34 extending backward from the fixing portion 31 on both sides of the locking member 3. The pair of extension arms 34 are located on the outside of the welding foot 33 in the lateral direction, and each of the extension arms 34 and the welding foot 33 on the same side are spaced apart in the lateral direction, thereby preventing the risk of deflection of the locking member 3 during assembly, making the force more balanced, and thus improving the convenience of assembly.
