[0003] With the increasing popularity of high-speed transmission in recent years, more and more electronic devices are adopting USB-C electrical connectors. Consequently, issues surrounding USB-C electrical connectors have gradually surfaced. For example, due to its short, thin and lightweight nature, USB-C electrical connectors can be used in a wide range of electronic devices. However, the problem lies in the fact that this short, thin and light nature can lead to improper plugging and unplugging by users for a long time, causing the shielding shell to warp and deform, or even break, making it impossible to use properly and relatively difficult to repair.

[0004] Therefore, how to solve the above-mentioned conventional problems and deficiencies has become the direction of research and improvement that the applicant of the present utility model and related manufacturers engaged in this industry are eager to study. Utility Model Content

[0005] The main purpose of the present invention is to provide an electrical connector that effectively enhances the overall strength and durability of the shielding shell through the upper and lower support design of the first surface connection portion and the second surface connection portion, thereby preventing deformation, damage or breakage caused by improper plugging and unplugging actions by the user.

[0006] In order to achieve the above-mentioned main purpose, the present invention provides an electrical connector, characterized by comprising:

[0007] a transmission conductor set having a welding portion set at a rear side thereof;

[0008] an insulating colloid group for the transmission conductor group;

[0009] A shielding shell covering the insulating colloid group, comprising:

[0010] a front section portion having a front section portion first surface on one side and a front section portion second surface on the other side;

DETAILED DESCRIPTION

[0036] See also Figures 1 to 3 As shown, it is a three-dimensional diagram of the first preferred embodiment of the present invention. Figure 1 As for the plug-in schematic diagram, it can be clearly seen from the figure that the utility model includes:

[0037] A transmission conductor set 1 has a welding portion set 11 at the rear side and can further be arranged in a single row;

[0038] an insulating colloid group 2 for the transmission conductor group 1;

[0039] A shielding shell 3 covering the insulating colloid group 2 includes:

[0040] A front section 31 has a front section first surface 311 on one side and a front section second surface 312 on the other side;

[0041] a rear section 32 located on one side of the front section 31 and having a width greater than that of the front section 31 , and having a rear section first surface 321 on one side and a rear section second surface 322 on the other side;

[0042] a first surface connecting portion 33 located between the front section first surface 311 and the rear section first surface 321 , such that the front section first surface 311 , the rear section first surface 321 , and the first surface connecting portion 33 are integrally formed; and

[0043] A second surface connecting portion 34 is located between the front section second surface 312 and the rear section second surface 322 .

[0044] The transmission conductor set 1 complies with the USB-C communication protocol specification.

[0045] The shielding shell 3 is integrally formed.

[0046] The width of the rear section 32 is greater than that of the front section 31 , so that the electrical connector of this embodiment has a convex shape as a whole.

[0047] In this embodiment, the second surface connection portion 34 is formed by integrally extending from the front section second surface 312 to the rear section second surface 322 and interconnected with the rear section second surface 322 as an example, and the interconnected position is as an example of being flatly attached and close to each other.

[0048] When the user inserts the opponent electrical connector 5 and the electrical connector of this case into each other, if the insertion angle is incorrect, for example, when inserting diagonally from top to bottom, a stress supporting the circuit board can be generated by the second surface connection portion 34, so that the front section 31 will not be tilted or deformed. If the insertion is diagonally from bottom to top, the second surface connection portion 34 will also generate a stress supporting the insulating colloid group 2, so that the front section 31 will not be tilted or deformed. In particular, when the second surface connection portion 34 is combined with the first surface connection portion 33, the overall stability and durability can be further increased.

[0049] See also Figure 4 As shown in the figure, it is a three-dimensional diagram of the second preferred embodiment of the present invention. It can be clearly seen from the figure that the difference between this embodiment and the first preferred embodiment is that the position where the second surface connecting portion 34 and the second surface 322 of the rear section portion are combined with each other has at least one second surface fixing portion 35. The second surface fixing portion 35 can be one of an n-shaped pattern or a dovetail groove pattern. This embodiment takes the dovetail groove pattern as an example. Thus, through the design of the second surface fixing portion 35, the second surface connecting portion 34 and the second surface 322 of the rear section portion are more firmly combined and not easy to separate.

[0050] See also Figure 5 As shown in FIG. 3 , a three-dimensional view of the third preferred embodiment of the present invention is shown. It can be clearly seen from the figure that the difference between this embodiment and the first preferred embodiment is that the second surface connection portion 34 of this embodiment is integrally formed and extends from the second surface 322 of the rear section to the second surface 312 of the front section, and is interconnected with the second surface 312 of the front section. This illustrates that the second surface connection portion 34 of this case, whether extending from the second surface 312 of the front section or from the second surface 322 of the rear section, is within the scope of protection of this case, and the effect achieved is the same as above, so it will not be repeated.

[0051] See also Figure 6 As shown, it is a three-dimensional view of the fourth preferred embodiment of the present invention. It can be clearly seen from the figure that the difference between this embodiment and the third preferred embodiment is that the position where the second surface connecting portion 34 and the second surface 312 of the front section portion are combined with each other has at least one second surface fixing portion 35, and the second surface fixing portion 35 is one of an n-shaped pattern or a dovetail groove pattern. This embodiment takes the n-shaped pattern as an example to illustrate that the design of the second surface fixing portion 35 in this case makes the second surface connecting portion 34 and the second surface 312 of the front section portion more firmly combined and not easy to separate.

[0052] See also Figure 7As shown in the figure, it is a three-dimensional diagram of the fifth preferred embodiment of the present invention. It can be clearly seen from the figure that the difference between this embodiment and the first preferred embodiment is that the second surface connection portion 34 of this embodiment is integrally formed and extends from the second surface 312 of the front section to the second surface 322 of the rear section, and a gap 36 is formed between the second surface connection portion 34 and the second surface 322 of the rear section. This illustrates that the second surface connection portion 34 of this case does not necessarily need to be connected to the second surface 322 of the rear section, and only needs to have a protruding second surface connection portion 34 design, which can also achieve the advantage of preventing deformation of the shielding shell 3 in this case.

[0053] See also Figure 8 As shown, it is a three-dimensional view of the sixth preferred embodiment of the utility model. It can be clearly seen from the figure that the difference between this embodiment and the fifth preferred embodiment is that the second surface connection portion 34 of this embodiment is integrally formed and extends from the second surface 322 of the rear section to the second surface 312 of the front section, and a gap 36 is formed between the second surface connection portion 34 and the second surface 312 of the front section. This illustrates that the second surface connection portion 34 of this case does not necessarily need to be connected to the second surface 312 of the front section, and only needs to have a protruding second surface connection portion 34 design, which can also achieve the advantage of preventing deformation of the shielding shell 3 in this case.

[0054] See also Figure 9 As shown in FIG. 1 , a perspective view of the seventh preferred embodiment of the present invention is shown. As can be clearly seen from the figure, the difference between this embodiment and the first preferred embodiment is that the electrical connector of this embodiment is an upright type and also has the design of the second surface connecting portion 34 and the second surface fixing portion 35, so that the front section portion 31 and the rear section portion 32 are firmly interlocked with each other, effectively preventing the front section portion 31 from tilting and deforming toward one side, and improving the overall durability.

[0055] See also Figure 10 As shown in FIG. 8 , a three-dimensional view of the eighth preferred embodiment of the present invention is shown. It can be clearly seen from the figure that the difference between this embodiment and the seventh preferred embodiment is that a gap 36 is formed between the second surface connection portion 34 of this embodiment and the second surface 322 of the rear section. This illustrates that the second surface connection portion 34 of this case does not necessarily need to be connected to the second surface 322 of the rear section. It only needs to have an outwardly protruding second surface connection portion 34 design, which can also achieve the advantage of preventing deformation of the shielding shell 3 in this case.

[0056] See also Figure 11As shown in the figure, it is a three-dimensional diagram of the ninth preferred embodiment of the present invention. It can be clearly seen from the figure that the difference between this embodiment and the first preferred embodiment is that a reinforcement member 4 is provided on the first surface 311 of the front section and the first surface 321 of the rear section of this embodiment, wherein the reinforcement member 4 is an iron sheet and can be combined by welding. This can further enhance the overall strength of the shielding shell 3, especially when the user inserts it obliquely from top to bottom or from bottom to top, or even shakes it up and down when pulling it out, the first surface connection portion or the second surface connection portion will not bend or deform.
