[0028] The present invention will now be described in detail with reference to the accompanying drawings.

[0029] like Figures 1 to 3 As shown, a male connector with mating compatibility according to this utility model includes a hook 1, an upper terminal assembly 2 and a lower terminal assembly 3 disposed on the hook 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, an upper terminal molding component 22 disposed on the upper electromagnetic interference component 21, an upper row of end feet 23 disposed on the upper terminal molding component 22, and a first gate component 24 disposed on the upper row of end feet 23. The lower terminal assembly 3 includes a lower electromagnetic interference component 31, a lower terminal molding component 32 disposed on the lower electromagnetic interference component 31, a lower row of end feet 33 disposed on the lower terminal molding component 32, and a second gate component 34 disposed on the lower row of end feet 33.

[0030] By adjusting the number of upper row end feet 23 and lower row end feet 33 using different cutting methods, the first sprue part 24 and the second sprue part 34 can be eliminated. This facilitates the production of 9-pin and 5-pin finished products, enabling the production of two different sizes from a single material, thus achieving high compatibility. This invention allows for adjusting the number of upper row end feet 23 and lower row end feet 33 using different cutting methods, making operation simple and convenient, and meeting the needs of compatible use.

[0031] In this embodiment, the upper terminal molded part 22 is provided with connecting posts 25 on both the front and back sides. The upper electromagnetic interference part 21 is provided with connecting holes 26 for accommodating the connecting posts 25. Connecting blocks 27 are provided on both sides of the upper terminal molded part 22. Connecting grooves 28 for accommodating the connecting blocks 27 are provided on both sides of the upper electromagnetic interference part 21. The hook part 1 is provided with mounting holes 11. The connecting posts 25 protrude into the mounting holes 11. Specifically, since connecting posts 25 are provided on both the front and back of the upper terminal molded part 22, the connecting posts 25 provided on the front of the upper terminal molded part 22 are inserted into the connecting holes 26. Moreover, the two sides of the upper terminal molded part 22 are connected to the connecting grooves 28 through connecting blocks 27, which facilitates the connection and positioning between the upper terminal molded part 22 and the upper electromagnetic interference component 21. The connecting posts 25 provided on the back of the upper terminal molded part 22 are connected to the mounting holes 11 of the hook component 1, realizing the connection and assembly of the upper terminal assembly 2 and the hook component 1. The positioning accuracy is high and the assembly efficiency is high.

[0032] In this embodiment, the top of the upper electromagnetic interference component 21 is provided with two first electromagnetic interference plates 29, which are spaced apart and arranged in parallel. Each of the two first electromagnetic interference plates 29 is provided with a first locking block 210 and a first protrusion 211. 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 locking block 36 and a second protrusion 37. The front and back of the housing 4 are respectively provided with a first locking groove 41 and a second locking groove 42. The first locking block 210 is engaged with the first locking groove 41, and the second locking block 36 is engaged with the second locking groove 42. The outer walls of the first protrusion 211 and the second protrusion 37 abut against the inner wall of the housing 4. Specifically, two first electromagnetic interference (EMI) plates 29 are spaced apart and parallel, and each of the two first EMI plates 29 is provided with a first protrusion 211. Two second EMI plates 35 are spaced apart and parallel, and each of the two second EMI plates 35 is provided with a second protrusion 37. When the outer walls of the two first protrusions 211 and the two second protrusions 37 abut against the inner wall of the housing 4, the contact friction is increased, improving the connection stability between the upper EMI plate 21, the lower EMI plate 31 and the housing 4. Moreover, through the contact with the housing 4, they also act as grounding devices, thereby using the first EMI plates 29 and the second EMI 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. When the first locking block 210 engages with the first locking slot 41, and the second locking block 36 engages with the second locking slot 42, the connection stability between the upper EMI plate 21, the lower EMI plate 31 and the housing 4 is effectively enhanced, ensuring normal operation.

[0033] In this embodiment, the lower terminal molding 32 is provided with a boss 38, and the hook 1 is provided with a groove 12 for accommodating the boss 38. The lower electromagnetic interference component 31 has locking posts 39 on both sides, and the lower terminal molding 32 has locking slots 310 on both sides for accommodating the locking posts 39. Specifically, when the lower terminal molding 32 protrudes into the groove 12 through the boss 38, the locking connection between the boss 38 and the groove 12 not only increases the contact area but also provides good limiting effect, preventing the lower terminal molding 32 from loosening and falling off on the hook 1. Furthermore, the lower electromagnetic interference component 31 protrudes into the locking slot 310 through the locking posts 39, allowing the lower electromagnetic interference component 31 to be positioned on the lower terminal molding 32. This enables the lower terminal assembly 3 to be assembled and fixed on the hook 1, with the hook 1 positioned between the upper terminal assembly 2 and the lower terminal assembly 3, serving as a support for assembly.

[0034] In this embodiment, the hook 1 is provided with a surface mount pin 13 and a through-hole pin 14 at one end near the groove 12. Specifically, the hook 1 is electrically connected to the external PCB board via the surface mount pin 13, and the hook 1 is locked and fixed to the housing 4 via the through-hole pin 14. The structure is compact and the design is reasonable, effectively saving space.

[0035] In this embodiment, the upper terminal molded part 22 is provided with a limiting block 212, and the housing 4 is provided with a limiting groove 43 for accommodating the limiting block 212. Specifically, when the outer wall of the limiting block 212 abuts against the inner groove wall of the limiting groove 43, the position of the upper terminal molded part 22 on the housing 4 is limited, and the limiting effect is good.

[0036] 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.
