[0064] The detailed description and technical contents of the present invention will be described as follows with reference to the drawings. However, the drawings are only for illustration purposes and are not intended to limit the present invention.

[0065] The present invention provides an electrical connector structure, please refer to Figures 1 to 5 As shown, it mainly includes a base 10, a tongue plate 20, a plurality of metal conductors 30, a covering member 40 and a side cover 50.

[0066] In this embodiment, the base 10 is integrally formed by plastic injection molding, but the present invention is not limited thereto. For example, the base 10 may also be made of other insulating materials. The base 10 has a receiving groove 11, a through groove 12, and a pair of positioning grooves 13. Specifically, the receiving groove 11 is disposed on the rear side of the base 10, the through groove 12 longitudinally penetrates the front side and the rear side of the base 10 and communicates with the receiving groove 11, and each positioning groove 13 is respectively located on both sides of the receiving groove 11 and the through groove 12.

[0067] The tongue plate 20 has a lap portion 21, a welding portion 22 and a pair of abutting portions 23. The welding portion 22 is connected to the rear side of the lap portion 21, and each abutting portion 23 extends from the left and right sides of the welding portion 22. A plurality of lap metal strips 201 of different lengths are embedded in the tongue plate 20, and the two ends of each lap metal strip 201 are exposed at the lap portion 21 and the welding portion 22, respectively, so as to be configured for lap connection with a docking connector (not shown) and for electrical connection with each metal conductor 30. The tongue plate 20 is inserted into the through slot 12 from the rear side of the base 10, so that the lap portion 21 passes through the front side of the base 10 and is exposed to the outside for lap connection with the docking connector, and the welding portion 22 is accommodated in the receiving slot 11, and each abutting portion 23 is respectively inserted into each positioning slot 13 so that the front side of each abutting portion 23 abuts against the end surface of each positioning slot 13.

[0068] In this embodiment, each metal conductor 30 is made of a metal material or metal alloy with good electrical conductivity. One end of each metal conductor 30 is connected to the welding portion 22 of the tongue plate 20, and is bent downward and extended from the welding portion 22. Specifically, each metal conductor 30 in this embodiment includes a metal terminal and a metal wire, the metal terminal is welded to the upper surface of the welding portion 22, and the metal wire is bent and extended vertically downward, but the present invention is not limited thereto.

[0069] The covering member 40 is disposed in the receiving groove 11 and covers at least a portion of the welding portion 22 and at least a portion of each metal conductor 30, so as to fix each metal conductor 30 so that it does not shake. In the present embodiment, the covering member 40 is disposed in the receiving groove 11 by injection molding to cover at least a portion of the welding portion 22 and at least a portion of each metal conductor 30, but the present invention is not limited thereto. The covering member 40 has a pair of side planes 41. Each side plane 41 is respectively located on the left and right sides of the covering member 40. Each side plane 41 respectively closes the connection between the through groove 12 and each positioning groove 13, thereby forming a groove body having only one notch (not numbered in the figure) together with each positioning groove 13, and each notch faces the rear side of the base 10.

[0070] In the present embodiment, the side cover 50 is integrally formed by plastic injection molding, but the present invention is not limited thereto. For example, the side cover 50 may also be made of other insulating materials. The side cover 50 in the present embodiment is assembled on the rear side of the base 10 to cover the covering member 40, but the side cover 50 may also be directly injection molded on the rear side of the base 10. Specifically, the base 10 has a plurality of card blocks 14, and the side cover 50 has a plurality of buckle holes 51, and each card block 14 is buckled and fixed in each buckle hole 51. In the present embodiment, the number of the card blocks 14 and the buckle holes 51 are both four and are respectively arranged on the left and right sides of the base 10 or the side cover 50 and the two sides of the top, but the present invention is not limited thereto. The side cover 50 has a pair of positioning posts 52. Each positioning post 52 is respectively located on the left and right sides of the front side of the side cover 50. Each positioning post 52 is respectively inserted into each positioning groove 13 through a notch.

[0071] Thus, the electrical connector structure of the present invention has two positioning grooves 13 located on both sides of the slot on the base 10, so that each abutting portion 23 of the tongue plate 20 can abut against each positioning groove 13 respectively, and each positioning column 52 of the side cover 50 is respectively inserted into each positioning groove 13, thereby ensuring that the assembly of the tongue plate 20, the base 10, each metal conductor 30 and the covering member 40 can be accurate and stable, thereby saving production costs.

[0072] For further explanation, see Figure 1 and Figure 2 As shown, the electrical connector structure of the present invention further includes a locking member 60, a drawstring 70 and abutting rod 80. The locking member 60 and the abutting rod 80 are respectively arranged on the base 10. The abutting rod 80 is arranged on the rear side of the locking member. The top of the base 10 has a pair of first accommodating grooves 15, and the top of the side cover 50 has a pair of second accommodating grooves 53. Each first accommodating groove 15 and each second accommodating groove 53 together cover the two ends of the abutting rod 80, thereby fixing the abutting rod 80. The drawstring 70 passes through the locking member 60, and the drawstring 70 is located between the locking member 60 and the abutting rod 80, so that one side of the drawstring 70 abuts against the abutting rod 80.

[0073] Specifically, the locking member 60 includes a fixing portion 61, an elastic bending portion 62 and a locking portion 63. The fixing portion 61 is a pair of protrusions 16 fixed to the top of the base 10 by a pair of card slots 611, so as to longitudinally limit the fixing portion 61. The locking portion 63 in this embodiment is generally in an inverted N shape, but the present invention is not limited to this. A pair of locking blocks 631 for buckling with the docking connector are formed on the locking portion 63. The two ends of the elastic bending portion 62 are respectively connected to the front end of the fixing portion 61 and the front end of the locking portion 63, so that a collapse space 64 is formed between the fixing portion 61 and the locking portion 63. More specifically, the elastic bending portion 62 is arc-shaped and connects the fixing portion 61 and the locking portion 63, and the number of the elastic bending portions 62 in this embodiment is two. The drawstring 70 is passed through the rear end of the locking portion 63. Thus, when the pull belt 70 is pulled backward, the pull belt 70 drives the locking portion 63 to move toward the collapsed space 64 with the abutment rod 80 as a fulcrum, thereby enabling each locking block 631 on the locking portion 63 to move downward to disengage from the lock with the docking connector.

[0074] Furthermore, the base 10 has a baffle plate 17 extending from above each first receiving groove 15 . Each baffle plate 17 stops at two sides of the locking portion 63 , thereby vertically restricting the locking member 60 to prevent the locking member 60 from being separated from the base 10 .
