For example, the insulating body 10 can also be an integral member or a two-piece member fixedly combined in other forms. The insulating body 10 has a limiting space 101. Specifically, the first housing 11 has a groove, and after the first housing 11 is assembled to the second housing 12, the groove and the first housing 11 jointly form the aforementioned limiting space 101. In this embodiment, the limiting space 101 is formed at the top of the front end of the insulating body 10, but in other embodiments, it can also be formed at the bottom or side of the front end of the insulating body 10.

[0058] The plug-in male head 20 is a concave flat-round metal column, and a plurality of pins (not labeled in the figure) are provided inside it. Since USB Type-C has clear specifications for its interface, dimensions, and the arrangement of each pin, and these are not the main technical focuses of the present utility model, they are omitted here and will not be elaborated further. The plug-in male head 20 is provided at the front end of the insulating body 10. Specifically, the plug-in male head 20 passes through the front end of the first housing 11 and is partially exposed at the front end of the insulating body 10, so as to facilitate insertion into the Type-C female connector B.

[0059] In this embodiment, the locking member 30 is an integral metal part, but the present invention is not limited thereto. The locking member 30 includes a connecting portion 31, an elastic portion 32, a locking portion 33, a positioning portion 34 and an unlocking portion 35. The connecting portion 31 is fixed on the male plug 20. In this embodiment, the connecting portion 31 is fixed on the top of the male plug 20 by welding, but the present invention is not limited thereto. The connecting portion 31 can also be fixed on the male connector by spot welding, riveting, locking, welding or other means. Or the connecting portion 31 can also be fixed on the bottom or side of the male plug 20. The elastic portion 32 is connected between the connecting portion 31 and the positioning portion 34. The locking portion 33 is disposed on the elastic portion 32. The positioning portion 34 is movably restricted within the limiting space 101. The unlocking portion 35 extends reversely from the positioning portion 34 toward the elastic portion 32. Specifically, the locking member 30 is connected and fixed to the male plug 20 by the connecting portion 31, and the elastic portion 32, the locking portion 33, the positioning portion 34 and the unlocking portion 35 are all in a suspended configuration.

[0060] Therefore, please refer to Figures 5 to 8 As shown, in the Type-C male connector A of the present invention, the elastic portion 32 and the locking portion 33 of the locking member 30 are in a suspended configuration, so that the Type-C male connector A can be snap-locked when plugged into the mating Type-C female connector B, thereby effectively preventing loosening when subjected to vibration or pulling.

[0061] Furthermore, the elastic portion 32 is folded back from the side of the connecting portion 31 away from the insulating body 10, and the elastic portion 32 extends obliquely toward the insulating body 10 after being folded back. Specifically, the elastic portion 32 includes a folded-back section 321 and a suspended section 322. The folded-back section 321 is in an inverted U shape, and the folded-back section 321 is connected between the front end of the connecting portion 31 and the front end of the suspended section 322, so that the suspended section 322 is in a suspended configuration to form a pressing space S between the suspended section 322 and the male plug 20. The suspended section 322 is connected to the positioning portion 34, and the locking portion 33 is disposed on the suspended section 322. In this embodiment, the locking portion 33 includes a pair of barbs 331, but the present invention is not limited thereto. The barbs 331 are spaced apart from each other on the left and right sides of the elastic portion 32, and each barb 331 protrudes from the elastic portion 32 in a direction away from the male plug 20.

[0062] The insulating body 10 has a pair of limiting covers 102. Specifically, each limiting cover 102 is disposed on the first housing 11 and is respectively located on opposite sides of the limiting space 101, so as to respectively stop opposite sides of the positioning portion 34. The positioning portion 34 includes an inclined section 341 and a pair of baffles 342. The inclined section 341 extends obliquely away from the plugging male head 20 from the elastic portion 32 to connect to the unlocking portion 35. Each baffle 342 is respectively located on opposite sides of the inclined section 341 and is substantially parallel to the plugging male head 20. Accordingly, since the elastic portion 32, the locking portion 33, the positioning portion 34 and the unlocking portion 35 of the locking member 30 are all in a suspended configuration, and its connecting portion 31 is fixedly connected to the plugging male head 20, under the influence of its own elastic force, the locking member 30 will cause the respective baffles 342 of the positioning portion 34 to respectively abut against the lower sides of the respective limiting covers 102 in a state without external force. When the user presses the unlocking portion 35, the respective baffles 342 of the positioning portion 34 will disengage from the respective limiting covers 102, so that the elastic portion 32 of the locking member 30 will move toward the pressing space S and the locking portion 33 will also move relatively toward the pressing space S to achieve the unlocking effect.

[0063] Please continue to refer to Figures 1 to 5 As shown, the present utility model further provides a Type-C connector assembly, including a Type-C female head connector B and a Type-C male head connector A.

[0064] The Type-C female head connector B includes a plugging female head 40 and a metal housing 50. The plugging female head 40 is an inwardly convex flat-round metal column, and a plurality of pins (not labeled in the figure) are also provided inside thereof. Since USB Type-C has clear specifications for its interface, size, and the arrangement of each pin, and these are not the main technical focuses of the present utility model, they are omitted here and will not be elaborated further. The plugging female head 40 has a relief notch 41. Specifically, the position of the relief notch 41 corresponds to the position of the connecting portion 31 of the locking member 30 and is located at the top of the front end of the plugging female head 40, but it can also be located at the bottom or side of the front end of the plugging female head 40 according to different positions of the connecting portion 31. The metal housing 50 covers the outside of the plugging female head 40 to further enhance the shielding effect. The metal housing 50 has a through groove 501. The through groove 501 is disposed corresponding to the position of the relief notch 41 and is located at the top of the plugging female head 40.

[0065] The specific structure of the Type-C male connector A is as described above, so it will not be repeated here. The Type-C male connector A can be detachably plugged into the Type-C female connector B. When the Type-C male connector A is plugged into the Type-C female connector B, the plug-in male connector 20 is inserted into the front end of the plug-in female connector 40, so that a part of the elastic portion 32 is accommodated in the clearance gap 41 without interference, and each barb 331 of the locking portion 33 is buckled with the through slot 501 to lock the Type-C male connector A and the Type-C female connector B. When unlocking, the user only needs to press the unlocking portion 35 of the locking member 30 so that each barb 331 of the locking portion 33 is disengaged from the through slot 501 to unlock the Type-C male connector A and the Type-C female connector B, and then pull the Type-C male connector A out of the Type-C female connector B.

[0066] Further explanation, the metal shell 50 includes an upper cover 51, a pair of side covers 52 and a back cover 53. The upper cover 51 is located at a distance on the top of the plug female connector 40, that is, there is a spacing (not numbered in the figure) between the upper cover 51 and the top of the plug female connector 40 to accommodate the elastic portion 32 of the locking member 30. Each side cover 52 is respectively connected to the opposite left and right sides of the upper cover 51 and the opposite left and right sides of the plug female connector 40, thereby fixing the metal shell 50 on the plug female connector 40. In this embodiment, each side cover 52 is respectively fixed to the left and right sides of the plug female connector 40 by welding, but the utility model is not limited thereto. For example, each side cover 52 can also be fixed to the left and right sides of the plug female connector 40 by riveting, snapping, locking, welding, etc. The back cover 53 is substantially vertically connected to the side of the upper cover 51 away from the Type-C male connector A, thereby shielding the rear end of the plug female connector 40 to form a shield.

[0067] The Type-C male connector A of the utility model is suspended in the air through the elastic portion 32 and the locking portion 33 of the locking member 30, so that when the Type-C male connector A is plugged into the docking Type-C female connector B, the barbs 331 of the locking portion 33 can be snap-locked in the through slots 501 of the metal shell 50, thereby effectively preventing the Type-C connector assembly from loosening due to vibration or pulling.

[0068] In summary, the foregoing disclosure of the present utility model is to enable those with ordinary knowledge in the art to clearly understand the technical content of the present utility model and implement it accordingly, rather than intending to limit the scope of patent protection of the present utility model. In addition, there are of course various other embodiments not listed for the present utility model.
