[0022] The present invention will now be described in detail with reference to the accompanying drawings.

[0023] like Figures 1 to 2As shown, this utility model discloses a dual-connection male connector, including a latch 1, an upper terminal assembly 2 and a lower terminal assembly 3 disposed on the latch 1, and a housing 4 sleeved on the outside of the upper terminal assembly 2 and the lower terminal assembly 3. The upper terminal assembly 2 includes an upper electromagnetic interference component 21 and an upper terminal molding component 22 disposed on the upper electromagnetic interference component 21. The upper terminal molding component 22 has a first positioning post 23 disposed on both its front and back sides. The upper electromagnetic interference component 21 is provided with a accommodating first positioning post 23. The lower terminal assembly 3 includes a first positioning hole 24, a lower electromagnetic interference component 31 and a lower terminal molding component 32 disposed on the lower electromagnetic interference component 31, a second positioning post 33 is provided on both the front and back sides of the lower terminal molding component 32, the lower electromagnetic interference component 31 is provided with a second positioning hole 34 for accommodating the second positioning post 33, the hook component 1 is provided with a connecting hole 11, the first positioning post 23 and the second positioning post 33 protrude into the connecting hole 11, and the housing 4 is provided with a laser welding point 41.

[0024] Since the upper terminal molded part 22 has first positioning posts 23 on both its front and back sides, the first positioning posts 23 on the front side of the upper terminal molded part 22 are inserted into the first positioning holes 24 to facilitate the connection and positioning of the upper terminal molded part 22 and the upper electromagnetic interference component 21. The first positioning posts 23 on the back side of the upper terminal molded part 22 are connected to the connecting holes 11 of the hook component 1. Similarly, since the lower terminal molded part 32 has second positioning posts 33 on both its front and back sides, the second positioning posts 33 on the front side of the lower terminal molded part 32 are connected to the connecting holes 11 of the hook component 1, and the second positioning posts 33 on the back side of the lower terminal molded part 32 are inserted into the second positioning holes 34 to facilitate the connection of the lower terminal molded part 32 and the lower electromagnetic interference component 31. The positioning system secures the connection between the upper electromagnetic interference component 21, the upper terminal molded component 22, the latch component 1, the lower terminal molded component 32, and the lower electromagnetic interference component 31. This ensures high positioning accuracy and assembly efficiency. Furthermore, the housing 4 is equipped with laser welding points 41, allowing for laser welding to create a melting zone. The high energy density of the laser melts the corresponding positions on the housing 4, further strengthening the connection between the housing 4 and the upper and lower electromagnetic interference components 21 and 31. Laser welding at these points provides double protection, preventing the upper and lower terminal components 2 and 3 from shifting or becoming loose within the housing 4. This invention employs a combination of latching and welding for dual connection and fixation, effectively ensuring the connector's connection stability and smooth operation during use, and extending its service life.

[0025] In this embodiment, the upper terminal molding 22 is provided with a limiting block 25, the bottom wall of which abuts against the top wall of the housing 4. Specifically, the upper terminal molding 22 abuts against the top wall of the housing 4 through the limiting block 25, limiting the position of the housing 4 in the upper terminal molding 22, providing a good limiting effect and preventing loosening and falling off.

[0026] In this embodiment, the top of the upper electromagnetic interference component 21 is provided with two first electromagnetic interference plates 26, which are spaced apart and arranged in parallel. Each of the two first electromagnetic interference plates 26 is provided with a first protrusion 27. The top of the lower electromagnetic interference component 31 is provided with two second electromagnetic interference plates 35, which are spaced apart and arranged in parallel. Each of the two second electromagnetic interference plates 35 is provided with a second protrusion 36. The outer walls of the first protrusion 27 and the second protrusion 36 abut against the inner wall of the housing 4. Specifically, two first electromagnetic interference plates 26 are arranged at intervals and in parallel, and each of the two first electromagnetic interference plates 26 is provided with a first protrusion 27. Two second electromagnetic interference plates 35 are arranged at intervals and in parallel, and each of the two second electromagnetic interference plates 35 is provided with a second protrusion 36. When the outer walls of the two first protrusions 27 and the two second protrusions 36 abut against the inner wall of the housing 4, the contact friction is increased, improving the connection stability between the upper electromagnetic interference component 21, the lower electromagnetic interference component 31 and the housing 4. Moreover, through the abutment with the housing 4, they also act as grounding devices, thereby using the first electromagnetic interference plates 26 and the second electromagnetic interference plates 35 to conduct some interference currents to ground, effectively reducing the impact of electromagnetic interference on the use of the connector and improving the safety performance of use.

[0027] In this embodiment, the upper terminal molded part 22 is provided with two accommodating grooves 28 spaced apart, and the first electromagnetic interference piece 26 protrudes into the accommodating groove 28. Specifically, when the first electromagnetic interference piece 26 protrudes into the accommodating groove 28, it can fix the position of the first electromagnetic interference piece 26 in the upper terminal molded part 22, thus providing good positioning.

[0028] In this embodiment, the upper electromagnetic interference component 21 is provided with a fixing post 29, which protrudes from the outer wall of the upper electromagnetic interference component 21. The lower electromagnetic interference component 31 is provided with a fixing groove 37, which is recessed from the outer wall of the lower electromagnetic interference component 31. The fixing post 29 is inserted and accommodated within the fixing groove 37. Specifically, when the hook component 1 is disposed between the upper terminal assembly 2 and the lower terminal assembly 3, the upper electromagnetic interference component 21 is inserted and accommodated within the fixing groove 37 through the fixing post 29, thereby enabling the upper electromagnetic interference component 21 and the lower electromagnetic interference component 31 to be interconnected and combined, resulting in a compact overall structure.

[0029] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
