Description

Technical Field

[0001] This application relates to the field of connector technology, specifically to a male connector. Background Technology

[0002] In modern electronic devices, electromagnetic compatibility (EMC) is a crucial design consideration. With the increasing complexity and integration of device functions, electromagnetic interference (EMI) issues have become increasingly prominent. Connectors, as indispensable components in electronic devices, directly impact the EMC performance of the entire system.

[0003] Existing non-waterproof connectors have inadequate shielding. They typically shield three sides of the terminal assembly but lack a fourth side, resulting in insufficient shielding. This incomplete shielding design can lead to electromagnetic interference leakage or intrusion, affecting normal equipment operation and signal integrity. Furthermore, poorly shielded connectors are particularly problematic in high-frequency applications, potentially increasing the bit error rate of signal transmission and even causing equipment malfunctions. Utility Model Content

[0004] The purpose of this application is to provide a male connector that can solve the technical problem that the shielding surface of current connectors is not perfect, resulting in leakage or intrusion of electromagnetic interference, which affects the normal operation of the equipment and signal integrity.

[0005] To address the aforementioned issues, this application provides a male connector comprising a first direction, a second direction, and a third direction that intersect each other. The male connector includes: a main body sheath having a mating end and a rear end in the first direction, the main body sheath having a receiving cavity extending through the mating end and the rear end along the first direction; a terminal assembly extending into the receiving cavity from the rear end toward the mating end; and a shielding assembly connected to the main body sheath, the shielding assembly including a first shield, a second shield, a third shield, and a fourth shield, the first shield and the second shield being connected between the third shield and the fourth shield, the first shield and the second shield being disposed within the receiving cavity and respectively disposed on both sides of the terminal assembly in the second direction, the third shield and the fourth shield being disposed outside the receiving cavity and respectively covering both sides of the main body sheath in the third direction.

[0006] The shielding assembly of this application includes a first shielding element, a second shielding element, a third shielding element, and a fourth shielding element. The first and second shielding elements are respectively disposed on both sides of the terminal assembly in the second direction, and the third and fourth shielding elements respectively cover both sides of the main body sheath in the third direction. The first and second shielding elements shield the terminal assembly on both sides in the second direction, and the third and fourth shielding elements shield the terminal assembly on both sides in the third direction. This increases the shielding surface area of ​​the terminal assembly, improves the shielding effect of the shielding assembly on the terminal assembly, avoids leakage or intrusion of electromagnetic interference, and avoids affecting the normal operation of the equipment and signal integrity.

[0025] Please see Figures 1-6 This embodiment provides a male connector 100. The male connector 100 includes a first direction M, a second direction N, and a third direction P that intersect each other. In this embodiment, the first direction M, the second direction N, and the third direction P are perpendicular to each other. The perpendicularity of the first direction M, the second direction N, and the third direction P can be understood as the included angle between each pair of the first direction M, the second direction N, and the third direction P being 80° to 90°, which is not limited here.

[0026] Please see Figure 1 The male connector 100 includes: a body sheath 1, a terminal assembly 2, and a shielding assembly 3.

[0027] Please see Figure 2The main body sheath 1 has a mating end 101 and a rear end 102 in the first direction M. The main body sheath 1 is provided with a receiving cavity 103 that passes through the mating end 101 and the rear end 102 in the first direction M. The mating end 101 refers to the end of the main body sheath 1 that is closer to the female connector, and the rear end 102 refers to the end of the main body sheath 1 that is away from the female connector and is used to accommodate the terminal assembly 2 through which it passes.

[0028] Please see Figure 2 and Figure 3 The main sheath 1 includes a first protective plate 11 and a second protective plate 12 arranged at intervals along the third direction P.

[0029] Please see Figure 3 The first guard plate 11 is provided with a first through hole 111 and a second through hole 112 arranged at intervals along the second direction N. The first through hole 111 and the second through hole 112 penetrate the first guard plate 11 along the third direction P.

[0030] Please see Figure 2 The second guard plate 12 is provided with a third through hole 121 and a fourth through hole 122 arranged at intervals along the second direction N. The third through hole 121 and the fourth through hole 122 penetrate the second guard plate 12 along the third direction P.

[0031] Please see Figure 2 and Figure 3 In the plane formed by the first direction M and the second direction N, the orthographic projection of the third through hole 121 lies within the orthographic projection of the first through hole 111, and the orthographic projection of the fourth through hole 122 lies within the orthographic projection of the second through hole 112. In this embodiment, the size of the third through hole 121 in the second direction N is the same as the size of the first through hole 111 in the second direction N, and the size of the third through hole 121 in the first direction M is smaller than the size of the first through hole 111 in the first direction M. The size of the fourth through hole 122 in the second direction N is the same as the size of the second through hole 112 in the second direction N, and the size of the fourth through hole 122 in the first direction M is smaller than the size of the second through hole 112 in the first direction M.

[0032] Please see Figure 1 and Figure 2 Terminal assembly 2 extends from rear end 102 toward mating end 101 into receiving cavity 103.

[0033] Please see Figure 4The main body sheath 1 has a first limiting part 104 in the receiving cavity 103 near the rear end 102, and a second limiting part 21 is provided on the terminal assembly 2. The second limiting part 21 and the first limiting part 104 cooperate with each other to lock the terminal assembly 2 in the receiving cavity 103. Specifically, the first limiting part 104 includes a hook, and the second limiting part 21 includes a protrusion. The first limiting part 104 is used to abut against the side of the second limiting part 21 near the rear end 102 to prevent the terminal assembly 2 from moving toward the rear end 102.

[0034] Please see Figure 1 and Figure 2 The shielding component 3 is connected to the main sheath 1. The shielding component 3 includes a first shielding element 31, a second shielding element 32, a third shielding element 33, and a fourth shielding element 34.

[0035] Please see Figure 1 and Figure 2 The first shielding member 31 and the second shielding member 32 are both connected between the third shielding member 33 and the fourth shielding member 34. The first shielding member 31 and the second shielding member 32 are both disposed within the receiving cavity 103 and respectively disposed on both sides of the terminal assembly 2 in the second direction N. The third shielding member 33 and the fourth shielding member 34 are both disposed outside the receiving cavity 103 and respectively cover both sides of the main body sheath 1 in the third direction P. By shielding the terminal assembly 2 on both sides in the second direction N with the first shielding member 31 and the second shielding member 32, and by shielding the terminal assembly 2 on both sides in the third direction P with the third shielding member 33 and the fourth shielding member 34, the shielding surface of the terminal assembly 2 is increased, improving the shielding effect of the shielding assembly 3 on the terminal assembly 2, preventing leakage or intrusion of electromagnetic interference, and avoiding affecting the normal operation of the equipment and signal integrity.

[0036] Please see Figure 5 The fourth shielding member 34 includes a first shielding portion 341 and a second shielding portion 342 arranged along the second direction N. The first shielding portion 341 has at least one snap-fit ​​portion 3411, and the second shielding portion 342 has at least one snap-fit ​​mating portion 3421 that engages with the snap-fit ​​portion 3411. The snap-fit ​​portion 3411 includes at least one of a snap-fit ​​protrusion and a snap-fit ​​groove. In this embodiment, the snap-fit ​​portion 3411 includes both a snap-fit ​​groove and a snap-fit ​​protrusion.

[0037] Please see Figure 6The third shielding member 33 covers the side of the first protective plate 11 away from the second protective plate 12, and the fourth shielding member 34 covers the side of the second protective plate 12 away from the first protective plate 11. Specifically, the first shielding member 31 passes through the first through hole 111 and connects to the third shielding member 33, and the second shielding member 32 passes through the second through hole 112 and connects to the third shielding member 33. The first shielding member 31 passes through the third through hole 121 and connects to the first shielding part 341, and the second shielding member 32 passes through the fourth through hole 122 and connects to the second shielding part 342. The first shielding member 31, the second shielding member 32, and the third shielding member 33 cooperate with each other to fix the shielding assembly 3 and the first protective plate 11; the first shielding member 31, the second shielding member 32, and the fourth shielding member 34 cooperate with each other to fix the shielding assembly 3 and the second protective plate 12.

[0038] It is worth noting that before the shielding component 3 is assembled to the main body sheath 1, the third shielding member 33 is connected between the first shielding member 31 and the second shielding member 32. The first shielding part 341 and the first shielding member 31 are arranged in a straight line along the third direction, and the second shielding part 342 and the second shielding member 32 are also arranged in a straight line along the third direction. In other words, the shielding component 3 is U-shaped overall. The first shielding member 31 and the first shielding part 341 extend into the first through hole 111, and the second shielding member 32 and the second shielding part 342 extend into the second through hole 112. Then, the first shielding part 341 extends into the third through hole 121, and the second shielding part 342 extends into the fourth through hole 122. Then, the first shielding part 341 and the second shielding part 342 are bent so that the snap-fit ​​part 3411 and the snap-fit ​​mating part 3421 fit together, thereby fixing the shielding component 3 and the main body sheath.
