[0037] Figure 1 This is a three-dimensional exploded view of the plug and socket provided in an embodiment of the present invention. The present invention provides a connector plug, its mating structure, and electrical connection wires. The connector plug 1 is used for interlocking with the socket 2. Please refer to the accompanying documentation. Figure 2As shown, the plug 1 includes a connecting body 10 and a housing assembly 11 disposed outside the connecting body 10; wherein:

[0038] The connecting body 10 has a plug connector 100 and a wire end member 101 extending from the end of the plug connector 100. In the embodiment of the present invention, the plug connector 100 is a universal connector, such as the USB Type-C standard, and may be the female end of the standard. The wire end member 101 includes a cable 102 electrically connected to the plug connector 100 and a wire wrapping portion 103 covering the cable 102. It can be explained that the electrical connection cable of the present invention is constructed by providing a plug 1 at one end of the cable 102 and electrically connecting to the cable 102 through the connecting body 10. The other end of the cable 102 may be configured with a connector of the same or different specifications (not shown) or directly connected to the required device (not shown) depending on the product requirements.

[0039] As described above, the outer shell assembly 11 includes an inner shell 110 and an outer shell 111 covering the inner shell 110. The inner shell 110 is sleeved on the outer wire portion 103 of the connecting body 10. The front end of the inner shell 110 has a plug interface 112 that protrudes from the front end of the outer shell 111. That is, the plug interface 112 is formed by continuously surrounding the side wall of the inner shell 110 to form a frame. The plug connector 100 further protrudes from the front end of the outer wire portion 103 and is located inside the plug interface 112.

[0040] Please refer to the following as well. Figure 1 and Figure 3 As shown, the socket 2 includes a docking body 20 and a docking shell 21. The docking body 20 also has a socket connector 200 of a universal specification that allows the plug 1 to be electrically connected, such as Type-C or other corresponding specifications. The docking shell 21 forms an insertion port 210. The docking body 20 is located in the insertion port 210 so that the inner shell 110 of the plug 1 can be inserted into the insertion port 210 with the shape formed by its front end sidewall, so that the socket connector 200 can be electrically connected to the plug connector 100.

[0041] like Figure 1 and Figure 4As shown, in this embodiment of the invention, at least one latching arm 113 is provided on the inner housing 110 of the plug 1. The latching arm 113 includes a pressing part 113a protruding from the outer housing 111 and a latching part 113b extending forward from the pressing part 113a and suspended on the side wall of the insertion interface 112. The mating housing 21 of the socket 2 is provided with at least one latching hole 211, which corresponds to the latching part 113b of the latching arm 113, so that when the plug connector 100 is inserted into the socket connector 200, the latching part 113b can be engaged with the latching hole 211. Specifically, as Figure 2 As shown, a groove for suspending the buckle 113b can be provided on the side wall of the insertion interface 112. The length of the groove can be extended according to the forming position of the pressing part 113a, and thus can be designed according to the required pressing amplitude of the pressing part 113a; furthermore, in conjunction with Figure 4 As shown, at least one recessed groove 103a can also be provided on the aforementioned wrapping portion 103 to correspond to the area below the pressing portion 113a, thereby increasing the space where the pressing portion 113a can be pressed downwards. Furthermore, as... Figure 3 As shown, the socket 2's mating housing 21 may also be provided with two guide parts 212 inside the insertion port 210. The two guide parts 212 are arranged opposite to each other on both sides of the socket connector 200, which can be used for alignment and guidance when the plug connector 100 is inserted.

[0042] Accordingly, Figure 5 As shown, when you want to remove the plug 1 from the socket 2, simply apply pressure to the pressing part 113a of the latch arm 113, for example by pressing it with your hand, so that the latch arm 113 is subjected to force and the latching part 113b bends and deforms inward, disengaging from the latching hole 211, and the plug 1 can be easily removed from the socket 2. Furthermore, the number of latch arms 113 can be increased; for example... Figure 2 As shown, in the embodiment of the present invention, there are two latching arms 113, which are respectively located on the two corresponding side walls of the insertion interface 112, and as... Figure 3 As shown, the number of buckle holes 211 is also set in a corresponding position and there are two of them.

[0043] Please see again Figure 2As shown in the embodiment of the present invention, in the connection between the inner shell 110 and the outer shell 111 of the plug 1, the inner shell 110 can be inserted from the front end of the outer shell 111, and a notch 111a is recessed at the front edge of the outer shell 111, corresponding to the pressing part 113a of the latching arm 113, so that when the inner shell 110 is inserted from the front end of the outer shell 111, the pressing part 113a can be accommodated in the notch 111a. In addition, latching holes 111b can be recessed on both sides of the front edge of the outer shell 111, and latching blocks 110c can be protruded at corresponding positions on the inner shell 110. After the above connection, the latching blocks 110c are engaged in the latching holes 111b, which helps the two to be connected.

[0044] Finally, please refer to the following: Figure 1 and Figure 2 As shown, in addition to the aforementioned structure, the electrical connection cable provided in this embodiment of the invention may also have a buffer structure 104 located at the end of the outer shell assembly 11 of the plug 1 on its cable 102. The buffer structure 104 can be formed by plastic injection molding and wrapped between the end of the wire wrapping part 103 and the cable 102. Furthermore, an inner connecting ring 110d may be provided at the end of the inner shell 110, and an outer connecting ring 111c may be provided at the end of the outer shell 111. When the inner shell 110 and the outer shell 111 are combined, the outer connecting ring 111c is sleeved on the inner connecting ring 110d and is wrapped together by the leading edge of the buffer structure 104.

[0045] Therefore, based on the above structure, the connector plug and its mating structure and electrical connection wire of the present invention can be obtained.

[0046] In summary, this invention possesses practicality, novelty, and inventiveness, fully meeting the requirements for a patent application. Therefore, this application is filed in accordance with patent law. Of course, this invention may have many other embodiments. Without departing from the spirit and essence of this invention, those skilled in the art can devise various corresponding changes and modifications based on this invention, but all such changes and modifications should fall within the protection scope of the patent application filed for this invention.
