[0002] With the rapid development of communication technology and the continuous improvement of transmission rates, the requirements for the transmission rate and other performance aspects of connectors are also increasing. To ensure connector performance, a shielding layer is set on the connector to block crosstalk between connector pins. However, in actual use, male connectors need to be mated and unmolded multiple times with female connectors, which can affect the integrity of the shielding layer and thus affect the performance of the connector.

[0003] Therefore, improvements to existing technologies are necessary. Summary of the Invention

The base has a first direction and a second direction perpendicular to each other. The base includes a bottom plate and at least two side plates. The first direction is perpendicular to the bottom plate. The side plates are respectively provided on both sides of the bottom plate in the second direction. The bottom plate and the at least two side plates cooperate to form a mating space for inserting a female connector. The bottom plate has a first through hole and a second through hole spaced apart from each other, both of which extend along the first direction. The connecting assembly includes a signal module and a first grounding pin. The signal module is inserted into the first through hole, and the first grounding pin is inserted into the second through hole. The side plates have a first mating surface facing the mating space. A conductive layer is applied to at least one of the surfaces of the bottom plate and / or the other surfaces of the side plates except for the first mating surface. The conductive layer is electrically connected to the first grounding pin to isolate crosstalk between the two signal modules.

[0006] Furthermore, the conductive layer is applied to all surfaces of the base plate and the side plate except for the first mating surface.

[0007] Furthermore, the base also has a third direction, with the first direction, the second direction, and the third direction being perpendicular to each other; the connecting assembly includes a first connecting unit and a second connecting unit, the first connecting unit and the second connecting unit being distributed along the third direction, and both the first connecting unit and the second connecting unit including the signal module and the first grounding pin arranged alternately along the second direction; the at least two side plates include a first side plate and a second side plate, the first side plate and the second side plate being located on both sides of the base plate in the second direction; in the first connecting unit, at least one of the signal modules is close to the first side plate relative to any of the first grounding pins; in the second connecting unit, at least one of the first grounding pins is close to the first side plate relative to any of the signal modules.

[0008] Furthermore, the base also has a reference plane, which is perpendicular to the third direction; the orthographic projections of the signal modules in the first connection unit and the second connection unit overlap on the reference plane.

[0009] Furthermore, the first connection unit and / or the second connection unit have a first end and a second end at their two ends in the second direction, respectively. The first end is provided with the signal module, and the second end is provided with the first grounding pin. The first end is also provided with a second grounding pin, which is disposed between the side plate and the signal module.

[0010] Furthermore, the base plate has a second mating surface and a third mating surface disposed opposite to each other in the first direction, the second mating surface being disposed between the two first mating surfaces; the base plate has a blind hole on one side of the third mating surface, the blind hole having a first hole segment and a second hole segment in the direction from the second mating surface to the third mating surface, the cross-sectional area of ​​the first hole segment being smaller than the cross-sectional area of ​​the second hole segment; the second grounding pin has a first insertion portion and a first connecting portion, the first insertion portion being inserted into the first hole segment, a portion of the first connecting portion being accommodated in the second hole segment, and the remaining portion extending out of the second hole segment.

[0011] Furthermore, the signal module includes a shielding block and at least one signal pin. The shielding block is inserted into the first through hole. The signal pin has a matching part, a transition part, a fixing part, and a second insertion part in sequence along the first direction. The matching part is housed in the mating space.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0033] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0034] The male connector and connector assembly of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, the descriptions of each embodiment in the following embodiments have different emphases; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0035] To address the problem in existing technologies where female and male connectors easily generate debris during insertion and removal, which can cause short circuits and affect overall performance, one embodiment of this application provides a male connector, including a base and a connecting assembly. The base has a first direction and a second direction perpendicular to each other. The base includes a bottom plate and at least two side plates. The first direction is perpendicular to the bottom plate. The side plates are respectively disposed on both sides of the bottom plate in the second direction. The bottom plate and the at least two side plates cooperate to form a mating space for inserting a female connector. The base plate has a first through hole and a second through hole spaced apart from each other, both extending along the first direction. The connecting assembly includes a signal module and a first grounding pin, the signal module being inserted into the first through hole and the first grounding pin being inserted into the second through hole. The side plate has a first mating surface facing the mating space. At least one surface of the base plate and / or the remaining surfaces of the side plate (excluding the first mating surface) is covered with a conductive layer, which is electrically connected to the first grounding pin to isolate crosstalk between the signal modules. This will be described in detail below.

[0036] See Figure 1 and Figure 10 In one embodiment, the male connector includes a base 10 and a connecting assembly 20, wherein the base 10 has a first direction perpendicular to each other (e.g., Figure 1 (As shown in the Z direction, the same below) and the second direction (as shown in the Z direction) Figure 1As shown in the X direction (hereinafter the same), the base 10 includes a base plate 11 and two side plates 12. The two side plates 12 are respectively disposed on both sides of the base plate 11 in the first direction. The two side plates 12 and the base plate 11 cooperate to form a mating space 13. The mating space 13 is used to insert a female connector to realize the mating use of the female connector and the male connector. The base plate 11 is provided with a first through hole 111 and a second through hole 112 that are spaced apart from each other. The first through hole 111 and the second through hole 112 both extend along the first direction. The connection component 20 includes a signal module 22 and a first grounding pin 23. The signal module 22 is inserted into the first through hole 111 and the first grounding pin 23 is inserted into the second through hole 112.

[0037] It should be noted that the base plate 11 and the side plate 12 are integrally formed and do not need to be used together. This arrangement improves the overall strength of the base 10, extends its service life, and ensures the correct positioning of the finished product, i.e., good guiding performance, which is conducive to the insertion and installation of the female connector and the male connector. The number of the side plates 12 is at least two, but not limited to this. In other embodiments, there may be three or four, depending on the actual needs of the male connector. Whether the side plates 12 are connected is not specifically limited, as long as it meets the usage requirements. One end of the signal module 22 and the first grounding pin 23 are housed in the mating space 13 for connection with the female connector, and the other end extends out of the base plate 11 away from the accommodating space after passing through the first through hole 111 and the second through hole 112, for connection to the PCB board. This will not be described in detail here.

[0038] Furthermore, the surface of the side plate 12 facing the mating space 13 is the first mating surface 121. This first mating surface 121 is the contact surface between the female connector and the side plate 12 when the male connector and the female connector are used together. The surface of the base plate 11 is covered with a conductive layer 14, but the first mating surface 121 is not covered with a conductive layer 14. In this embodiment, none of the side plates 12 are covered with a conductive layer 14 (e.g., Figure 10 As shown, the conductive layer 14 is electrically connected to the first grounding pin 23 to isolate crosstalk between signal modules 22 and improve the performance of the connector.

[0039] It should be noted that the conductive layer 14 on the surface of the base plate 11 includes conductive layers 14 on the walls of the first through holes 111 and the second through holes 112 provided in the base plate 11, which improves the shielding performance and ensures the performance of the connector. In this embodiment, the conductive layer 14 can be an electroplated nickel layer. The specific process is as follows: the surface of the base 10 is roughened to ensure the adhesion of the subsequent electroplating material, and then copper is plated on the entire surface of the base 10. To ensure that no nickel layer is electroplated on the two side walls, the side plates need to be... A dividing line is engraved at the junction of the base plate 12 and the base plate 11 by laser or laser engraving to separate the copper plating layers on the base plate 11 and the side plate 12. Then, the base plate 11 is nickel plated, while the side plate 12 is not nickel plated. Finally, the copper plating on the side plate 12 is stripped. This achieves the goal of setting a conductive layer 14 on the surface of the base plate 11 and not setting a conductive layer 14 on the surface of the side plate 12 in this embodiment. Of course, in some embodiments, it is also possible to achieve whether or not a conductive layer 14 is laid on different surfaces of the base 10 through other means, which will not be elaborated here.

[0040] Furthermore, in some embodiments, the first mating surface 121 is also provided with a guide groove (not shown in the figure), which facilitates the insertion of the female connector into the male connector, improving efficiency. Simultaneously, when inserting the female connector, it does not damage the signal module 22 and the first grounding pin 23, serving a positioning function. Moreover, the surface of the base plate 11 and all surfaces of the side plate 12, except for the first mating surface 121, are covered with a conductive layer 14 (such as...). Figure 9 As shown, the above processing technology can be used to achieve this, which will not be described in detail here. By not providing a conductive layer 14 on the side plate 12 except for the first mating surface 121, the shielding performance of the connector can be further improved, thereby improving the performance of the connector. Of course, in some embodiments, the conductive layer 14 can also be other forms of laying, which will not be described in detail here.

[0041] See Figure 2 and Figure 3 In one embodiment, the base 10 further has a third-party orientation (such as...) Figure 2(As shown in the Y direction, the same below), the first direction, the second direction and the third direction are perpendicular to each other; the connection component 20 includes a first connection unit 21 and a second connection unit 25. The first connection unit 21 and the second connection unit 25 are distributed along the third direction, and both the first connection unit 21 and the second connection unit 25 include the signal module 22 and the first grounding pin 23 arranged alternately along the second direction. In this embodiment, the two side plates 12 are the first side plate 122 and the second side plate 123, which are located on both sides of the bottom plate 11 in the second direction. In the first connection unit 21, at least one signal module 22 is close to the first side plate 122 relative to any of the first grounding pins 23. In the second connection unit 25, at least one first grounding pin 23 is close to the first side plate 122 relative to any of the signal modules 22.

[0042] It should be noted that in this embodiment, in the first connecting unit 21, the signal module 22 is arranged first at the end near the first side plate 122, then the first grounding pin 23 is arranged, and then the signal module 22 is arranged again, and so on alternately. In the second connecting unit 25, the first grounding pin 23 is arranged first at the end near the first side plate 122, then the signal module 22 is arranged, and so on alternately. The first connecting unit 21 and the second connecting unit 25 are arranged alternately in the third direction, which will not be elaborated here. This arrangement improves the coverage of the signal module 22 by the first grounding pin 23, improves the shielding performance, and thus improves the performance of the connector.

[0043] Please continue reading. Figure 2 In one embodiment, the base 10 further has a reference plane (e.g., Figure 2 As shown in the mid-plane α (hereinafter the same), the orthographic projections of the signal modules 22 in the first connecting unit 21 and the second connecting unit 25 on the reference plane overlap; arranged in this way, in the second direction ( Figure 2 In the horizontal direction (viewing from the side), the signal module 22 and the first grounding pin 23 are arranged in a staggered manner, which is beneficial to the wrapping of the signal module 22 by the first grounding pin 23, improves the shielding effect, and at the same time reduces the horizontal size, reduces the use of the first grounding pin 23, and saves the cost of use.

[0044] Please continue reading. Figure 3 In one embodiment, the first connection unit 21 and the second connection unit 25 are respectively a first end 211 and a second end 212 in the second direction. The first end 211 is provided with a signal module 22, and the second end 212 is provided with a first grounding pin 23. The first end 211 is also provided with a second grounding pin 24, which is disposed between the side plate 12 and the signal module 22.

[0045] It should be noted that the second grounding pin 24 is located between the side plate 12 and the signal module 22 closest to the side plate 12. The first grounding pin 23 and the second grounding pin 24 are provided at both ends in the horizontal direction of the first connecting unit 21 and the second connecting unit 25 to improve the shielding effect.

[0046] Please see Figure 3 and Figure 4 In one embodiment, the base plate 11 has a second mating surface 113 and a third mating surface 114 disposed opposite to each other in a first direction. The second mating surface 113 is disposed between the first mating surfaces 121 of the two side plates 12, and the base plate 11 is located on one side of the third mating surface 114 (i.e., Figure 3 A blind hole 115 is provided at the bottom of the base plate 11 (viewed from the center). The blind hole 115 has a first hole segment 1151 and a second hole segment 1152 in the direction from the second mating surface 113 to the third mating surface 114. The cross-sectional area of ​​the first hole segment 1151 is smaller than the cross-sectional area of ​​the second hole segment 1152. The second grounding pin 24 is inserted into the blind hole 115. With this arrangement, when the second grounding pin 24 is inserted, the second hole segment 1152 provides operating space for the insertion operation, which can ensure that the second grounding pin 24 is inserted in place and ensures reliable connection. With the blind hole 115, the second grounding pin 24 will not affect the insertion and use of the female connector and the male connector, and will not cause interference while improving the shielding performance.

[0047] Furthermore, the second grounding pin 24 has a first insertion portion 241 and a first connecting portion 242. The first insertion portion 241 is inserted into the first hole segment 1151, and the first connecting portion 242 is partially accommodated in the second hole segment 1152, with the remaining portion extending out of the second hole segment 1152 for connection with the PCB board. By accommodating a portion of the first connecting portion 242 in the second hole segment 1152, this arrangement ensures that when the first connecting portion 242 is connected to the PCB board, the first insertion portion 241 will not interfere with the PCB board, thus avoiding damage to the PCB board.

[0048] It should be noted that when the male connector and female connector are plugged in, the second mating surface 113 abuts against the female connector, and the third mating surface 114 abuts against the PCB board. In some embodiments, the portions of the signal module 22 and the first grounding pin 23 that are not connected to the PCB are positioned between the second mating surface 113 and the third mating surface 114, meaning they will not interfere with the connection and installation of the PCB beyond the third mating surface 114 (e.g., ...). Figure 5 , Figure 6 (as shown); and the cross-sections of the first hole segment 1151 and the second hole segment 1152 are obtained by transversely cutting through a surface perpendicular to the first direction.

[0049] See Figure 6 and Figure 7 In one embodiment, the signal module 22 includes a shielding block 221 and two signal pins 222. The shielding block 221 is inserted into the first through hole 111. The signal pins 222 have, along the first direction, a mating portion 2221, a transition portion 2222, a fixing portion 2223, and a second insertion portion 2224. The mating portion 2221 is housed in the mating space for connection with the female connector. The fixing portion 2223 is used to connect to the shielding block 221 and is disposed inside the shielding block 221. The second insertion portion 2224 is used to connect to the PCB board. The cross-sectional area of ​​the transition portion 2222 gradually increases from the mating portion 2221 to the second insertion portion 2224. During the insertion process of the female connector and the male connector, the signal pins 222 are subjected to a downward (…) Figure 8 The force (from the perspective) is ensured by the setting of the transition part 2222, which ensures the strength of the signal pin 222 and improves its service life.

[0050] It should be noted that the number of signal pins 222 is determined according to actual usage requirements and is not limited to this; the cross-section of the transition portion 2222 is obtained by cross-sectioning a surface perpendicular to the first direction; furthermore, in some embodiments, the wider side of the second grounding pin 24 faces the narrower side of the signal pin 222, thus improving the coverage of the signal pin 222 by the second grounding pin 24 and enhancing the shielding effect (e.g., Figure 6 (As shown).

[0051] Please continue reading. Figure 7 In one embodiment, the shielding block 221 has a clamping hole 2211, the axis of which is perpendicular to the fixing part 2223. During the manufacturing process of the signal module 22, the fixing part 2223 is clamped by a tool, and the shielding block 221 and the clamping hole 2211 are formed by injection molding. The tool can be removed through the clamping hole 2211 to facilitate injection molding production. In some embodiments, a fixing structure fixed to the first through hole 111 and a foolproof protrusion for installing the signal module 22 can also be provided on the side wall of the shielding block 221. It is not limited to these, and will not be described in detail here.

[0052] Please continue reading. Figure 8In one embodiment, a fastening structure 30 is provided between the fixing part 2223 and the shielding block 221. The fastening structure 30 includes a groove 31 and a protrusion 32. The protrusion 32 is accommodated in the groove 31. In this embodiment, the protrusion 32 is disposed on the shielding block 221 and the groove 31 is disposed on the fixing part 2223. In some embodiments, they can be arranged in reverse, which will not be described in detail here. By providing the protrusion 32 and the groove 31, the fastening degree between the fixing part 2223 and the shielding block 221 can be improved, and the signal pin 222 and the shielding block 221 will not have gaps or shaking during long-term insertion and removal, which would affect the insertion of the female connector and the male connector and affect the performance.

[0053] Furthermore, the length of the fixing part 2223 in the second direction is greater than the length of the fixing part 2223 in the third direction, and the groove 31 is provided on the side of the fixing part 2223 in the second direction, that is, the groove 31 is provided on the narrower side of the fixing part 2223. If the groove 31 is provided on the longer side of the fixing part 2223, the area where the groove 31 is provided in the fixing part 2223 will become thinner, affecting the strength of the fixing part 2223, and thus affecting the service life of the signal pin 222.

[0054] It should be noted that in some embodiments, the protrusion 32 and the groove 31 described above can be simultaneously provided on the shielding block 221 or the fixing part 2223 to enhance the connection between the fixing part 2223 and the shielding block 221, and are not limited thereto.

[0055] On the other hand, embodiments of this application also provide a connector assembly, including any of the above-mentioned male connectors, and the connector assembly further includes a female connector used for mating with the above-mentioned male connectors.

[0056] It should be noted that the above Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 9 and Figure 10 The shaded area in the figure represents conductive layer 14, and the shaded areas in the remaining figures are cross-sectional lines.

[0057] This application uses the mating space 13 enclosed by the base plate 11 and the side plate 12 to insert the female connector. The conductive layer 14 is not provided on the first mating surface 121 of the contact surface between the female connector and the side plate 12, while the conductive layer 14 is provided on the other surfaces of the base 10. This satisfies the need to block crosstalk between the two signal modules 22 and ensures that no debris of the conductive layer 14 is generated on the first mating surface 121 during the insertion and removal of the female connector and the male connector. Falling debris will affect the overall performance of the connector and is prone to short circuit.
