Mode for Carrying Out the Invention

[0007] Hereinafter, embodiments of the present invention will be described in detail. However, it can be understood that the embodiments provide many applicable concepts that can be implemented in various specific contents. The described and disclosed embodiments are only for the purpose of explanation and are not for limiting the scope of the present invention.

[0008] Referring to FIG. 1, FIG. 1 is a schematic diagram showing a high-frequency connector 100 configured by correspondingly joining a male connector 110 and a female connector 120 according to an embodiment of the present invention. The high-frequency connector 100 is applied to the transmission of high-frequency (e.g., millimeter-wave band) signals, and uses the shielding and grounding characteristics of metal members to reduce the loss caused by signal reflection or impedance mismatch of the transmitted signal, so that the signal can be transmitted more completely at high frequencies. As shown in FIG. 1, the high-frequency connector 100 includes a plurality of joining terminal groups 130, a first metal member 140, a plurality of second metal members 150, and an insulating case 160. The first metal member 140 and the second metal members 150 extend in the first direction D1 and the second direction D2, respectively, and are electrically grounded as a shield between the joining terminal groups 130, thereby improving the voltage standing wave ratio (VSWR) of the high-frequency connector 100 and the signal interference between the joining terminal groups 130 during signal transmission. In some embodiments, the high-frequency connector 100 of the present invention can be used in combination with a flexible print circuit (FPC), making the high-frequency connector 100 thinner, more movable, and capable of bending to a certain extent together with the flexible print circuit board, enhancing the application possibilities of the high-frequency connector 100.

[0009] Continuing to refer to FIG. 1, the joining terminal group 130 is configured by joining the male terminals of the male connector 110 and the female terminals of the female connector 120. Each of the joining terminal groups 130 includes one male terminal and one female terminal, and the joining terminal groups 130 are arranged and installed along the first direction D1. In some embodiments, installing a ground pin in the middle joining terminal group can reduce relatively less noise interference compared to installing a ground pin in any joining terminal group.

[0010] Continuing to refer to FIG. 1, the first metal member 140 extends along the first direction D1 and is installed in the insulating case 160. In this embodiment, the first metal member 140 is embedded / penetrated in the hole of the insulating case 160, and the top and bottom of the first metal member 140 are exposed through the holes of the insulating case 160, and both the top and bottom of the first metal member 140 are electrically grounded. In this way, the first metal member 140 is commonly grounded with the male connector 110 and the female connector 120 of the high-frequency connector 100, thereby increasing the transmission route of the current (signal) and further improving the voltage standing wave ratio of the high-frequency connector 100. In some embodiments, the first metal member 140 may have more portions that are exposed from the insulating case 160 and are electrically grounded. In some embodiments, the top surface and the bottom surface of the first metal member 140 may be aligned with the top surface and the bottom surface of the insulating case 160, or may be slightly recessed or protruded inward from the top surface and the bottom surface of the insulating case 160. In this way, the top and bottom of the first metal member 140 may be recessed into the holes of the insulating case 160, or may protrude outside the holes of the insulating case 160, and the present invention is not limited thereto.

[0011] In this embodiment, the top and bottom of the first metal member 140 have an uneven structure, and at least two portions of this uneven structure protrude outside the holes of the insulating case 160 and are electrically grounded. In some embodiments, the first metal member 140 may have different shapes to correspond to different connector structures. For example, the front end, the end, the top or the bottom of the first metal member 140 may have a protruding or recessed structure so that the first metal member 140 and the connector fit together with each other, and the present invention is not limited thereto. In some embodiments, the first metal member 140 may be an integrally formed structure or a member composed of a plurality of members. In addition, although only one first metal member 140 is shown in FIG. 1, actually, more first metal members 140 may be installed as needed.

[0012] Continuing to refer to FIG. 1, the second metal member 150 is installed between the bonding terminal groups 130, extends along a second direction D2 perpendicular to the first direction D1, and is installed in the insulating case 160. In an embodiment of the present invention, the uppermost and bottom portions of the second metal member 150 are exposed through holes (for example, between the bonding terminal group 130 and the first metal member 140) and slots (for example, between adjacent bonding terminal groups 130) of the insulating case 160, and both the uppermost and bottom portions of the second metal member 150 are electrically grounded. In this way, when the male connector 110 and the female connector 120 are joined to each other, the second metal member 150 forms a cut-off between the bonding terminal groups 130, further improves the signal interference between the bonding terminal groups 130, and can transmit signals more effectively. The second metal member 150 may have more portions exposed from the insulating case 160 and electrically grounded, and the present invention is not limited thereto. In some embodiments, the uppermost surface and the bottom surface of the second metal member 150 may be aligned with the uppermost surface and the bottom surface of the insulating case 160, may be slightly recessed inward from the uppermost surface and the bottom surface of the insulating case 160, or may protrude, and thus, the uppermost and bottom portions of the second metal member 150 may be recessed into the holes / slots of the insulating case 160, or may protrude outside the holes / slots of the insulating case 160. In addition to this, although only four second metal members 150 are shown in FIG. 1, actually, more second metal members 150 may be installed as needed. In some embodiments, the second metal member 150 may have different shapes to correspond to different connector structures. For example, the front end, the end, the uppermost portion, or the bottom portion of the second metal member 150 may have a protruding or recessed structure so that the second metal member 150 and the connector fit with each other, and the present invention is not limited thereto.

[0013] Continuing to refer to FIG. 1, in an embodiment of the present invention, each of the second metal members 150 is composed of a metal sheet 150a and a metal sheet 150b, and the metal sheet 150a and the metal sheet 150b do not contact each other. The metal sheet 150a extends between the bonding terminal group 130 and the first metal member 140 along the second direction D2, and the metal sheet 150b extends between adjacent bonding terminal groups 130 along the second direction D2. In an embodiment of the present invention, in order to obtain a better frequency response, the distance between the metal sheet 150a and the metal sheet 150b is at least 0.07λ, where λ is the wavelength of the high-frequency signal described above. For example, when the operating frequency of the high-frequency signal described above is 50 GHz and the wavelength of the high-frequency signal described above is 3.53 mm, the distance is at least 0.25 mm (0.07×3.53 mm). Only the second metal member 150 composed of two metal sheets (i.e., the metal sheet 150a and the metal sheet 150b) is shown in FIG. 1, but actually, the second metal member 150 may be composed of more metal sheets as required, and the present invention is not limited thereto. In some embodiments, the metal sheet 150a and the metal sheet 150b of the second metal member 150 may each have an integrally formed structure, or each may be a member composed of a plurality of members, and the present invention is not limited thereto.

[0014] In an embodiment of the present invention, FIG. 2 shows the influence of the connection relationship between the first metal member 140 and the second metal member 150 on loss when the operating frequency is 50 GHz. In FIG. 2, the reference point O1 indicates that the first metal member 140 and the second metal member 150 are connected to each other and there is no gap between the metal sheet 150a and the metal sheet 150b of the second metal member 150. The reference point O2 indicates that the first metal member 140 and the second metal member 150 are not connected and there is no gap between the metal sheet 150a and the metal sheet 150b of the second metal member 150. The reference point O3 indicates that the first metal member 140 and the second metal member 150 are not connected and there is a gap between the metal sheet 150a and the metal sheet 150b of the second metal member 150. As can be seen from FIG. 2, the reference point O3 has a smaller loss compared to the reference point O1 and the reference point O2. That is, when the first metal member 140 and the second metal member 150 are not connected and there is a gap between the metal sheet 150a and the metal sheet 150b of the second metal member 150, the loss can be reduced.

[0015] In an embodiment of the present invention, FIG. 3 shows the influence of the connection relationship between the first metal member 140 and the second metal member 150 on the voltage standing wave ratio when the operating frequency is 50 GHz. In FIG. 3, reference point O1 indicates that the first metal member 140 and the second metal member 150 are connected to each other and there is no gap between the metal sheet 150a and the metal sheet 150b of the second metal member 150. Reference point O2 indicates that the first metal member 140 and the second metal member 150 are not connected and there is no gap between the metal sheet 150a and the metal sheet 150b of the second metal member 150. Reference point O3 indicates that the first metal member 140 and the second metal member 150 are not connected and there is a gap between the metal sheet 150a and the metal sheet 150b of the second metal member 150. As can be seen from FIG. 2, the voltage standing wave ratio of reference point O3 is closer to 1 compared to reference point O1 and reference point O2. That is, when the first metal member 140 and the second metal member 150 are not connected and there is a gap between the metal sheet 150a and the metal sheet 150b of the second metal member 150, the voltage standing wave ratio can be made closer to 1, indicating that the smaller the signal reflection amount, the better the impedance matching.

[0016] In an embodiment of the present invention, FIG. 4 further shows the influence of the gap between the metal sheet 150a and the metal sheet 150b of the second metal member 150 on the loss and the voltage standing wave ratio when the operating frequency is 50 GHz. As can be seen from FIG. 4, when the gap between the metal sheet 150a and the metal sheet 150b is between 0.25 mm and 0.62 mm, it has a small loss and a voltage standing wave ratio close to 1, resulting in a preferable frequency response. Based on the above experimental data, in order to obtain a better frequency response, the gap between the metal sheet 150a and the metal sheet 150b can be defined as at least 0.07λ. For example, in the embodiment, when the operating frequency is 50 GHz and the wavelength is 3.53 mm, the gap between the metal sheet 150a and the metal sheet 150b is at least 0.25 mm (0.07×3.53 mm), that is, a preferable frequency response can be obtained.

[0017] Continuing to refer to FIG. 1, the insulating case 160 is configured by joining the male insulating case of the male connector 110 and the female insulating case of the female connector 120, and is configured to place the joining terminal group 130 thereon. That is, the male insulating case of the male connector 110 places a plurality of male terminals, and the female insulating case of the female connector 120 places a plurality of female terminals, so that the male terminals and the female terminals are joined to each other correspondingly to form the joining terminal group 130. In this embodiment, the insulating case 160 spaces the first metal member 140 and the second metal member 150 apart from each other so as not to contact each other.

[0018] In the embodiment shown in FIG. 1, the high-frequency connector 100 further includes a metal case 170 that substantially covers the insulating case 160, and this metal case 170 is configured by joining the metal case of the male connector 110 and the metal case of the female connector 120 to each other.

[0019] Based on the above content, FIGS. 5 and 6 are schematic diagrams showing the male connector 110 and the female connector 120 according to an embodiment of the present invention. The male connector 110 and the female connector 120 shown in FIGS. 5 and 6 can be used to realize the high-frequency connector 100 shown in FIG. 1, and other possible deformations can also be used within the scope not exceeding the scope of the present disclosure.

[0020] Referring to FIG. 5, the left side of FIG. 5 is a schematic diagram showing a metal member of a male connector 110 including a plurality of male terminals 111 and a male metal case 113 according to an embodiment of the present invention. The left side of FIG. 5 shows a male connector 110 including a male insulating case 112, and this male insulating case 112 is used to place the metal member (including the male terminals 111 and the male metal case 113) shown on the left side of FIG. 5. Specifically, the male insulating case 112 places the male terminals 111 and the male metal case 113, and the male metal case 113 substantially covers the male insulating case 112. In addition, the male insulating case 112 shown on the right side of FIG. 5 has a hole 114, a concave groove 116, and a concave groove 117 extending along the first direction D1, and a plurality of holes 115 extending along the second direction D2. In this embodiment, when the male connector 110 and the female connector 120 are joined to each other, the hole 114, the concave groove 116, and the concave groove 117 are used to correspondingly penetrate the first metal member 140, and the hole 115 is used to correspondingly penetrate the second metal member 150. Specifically, the uppermost and bottom portions of the first metal member 140 and the second metal member 150 are exposed from these holes and grooves and are electrically grounded.

[0021] Referring to FIG. 6, the right side of FIG. 6 is a schematic diagram showing a metal member of a female connector 120 including a plurality of female terminals 121, a female metal case 123, a first metal member 140, and a plurality of second metal members 150 according to an embodiment of the present invention. The right side of FIG. 6 is a schematic diagram showing a female connector 120 including a female insulating case 122 according to an embodiment of the present invention, and the female insulating case 122 is used to place the metal member (including the female terminals 121, the female metal case 123, the first metal member 140, and the second metal members 150) shown on the right side of FIG. 6. The female insulating case 122 places the female terminals 121, and the female metal case 123 substantially covers the female insulating case 122. In this embodiment, the first metal member 140 and the second metal members 150 are installed in the first direction D1 and the second direction D2 respectively, and when the male connector 110 and the female connector 120 are joined to each other correspondingly, they function as a cutoff between the joining terminal groups 130.

[0022] In this embodiment, the top and bottom of the first metal member 140 and the second metal member 150 both extend beyond the female terminal 121, the female insulating case 122, and the female metal case 123, and are electrically grounded when the male connector 110 and the female connector 120 are joined in a corresponding manner. In some embodiments, the top and bottom surfaces of the first metal member 140 and the second metal member 150 may be aligned with the top and bottom surfaces of the female insulating case 122, or may be slightly recessed or protruded inward from the top and bottom surfaces of the female insulating case 122. In this way, it should be understood that the top and bottom of the first metal member 140 and the second metal member 150 may be recessed into the holes / slots of the female insulating case 122, or may protrude outside the holes / slots of the female insulating case 122.

[0023] In addition to this, in the embodiments shown in FIGS. 5 and 6, both the first metal member 140 and the second metal member 150 are installed on the female connector 120. However, in some embodiments, the first metal member 140 and the second metal member 150 may be installed on the male connector 110. In some other embodiments, one of the first metal member 140 and the second metal member 150 is installed on the male connector 110, while the other is installed on the female connector 120. In some other embodiments, both the male connector 110 and the female connector 120 are where the first metal member 140 and the second metal member 150 are installed. It should be understood that any changes and modifications to the arrangement positions of the first metal member 140 and the second metal member 150 are within the scope of the present invention.

[0024] Figures 7 and 8 respectively show the male connector 210 and the female connector 220 according to other embodiments of the present invention.

Each of the second metal members 150 shown in FIGS. 1 and 6 is divided into a plurality of second male metal bodies 215 and a plurality of second female metal bodies 225, which are respectively installed on the male connector 210 and the female connector 220, and each of the second male metal bodies 215 and the second female metal bodies 225 is electrically grounded. It should be understood that the male connector 210 and the female connector 220 shown in FIGS. 7 and 8 can be used to realize the high-frequency connector 100 shown in FIG. 1, and other possible deformations can also be used within the scope not exceeding the present disclosure.

[0025] Referring to FIG. 7, the left side of FIG. 7 is a schematic diagram showing the metal members of the male connector 210 including a plurality of male terminals 211, a male metal case 213, a first male metal body 214, and a plurality of second male metal bodies 215 according to other embodiments of the present invention. Each of the second male metal bodies 215 includes a metal sheet 215a and a metal sheet 215b, and the metal sheet 215a and the metal sheet 215b are not connected to each other and have an interval distance of at least 0.07λ to obtain a better frequency response, where λ is the wavelength of the operating frequency. For example, when the operating frequency is 50 GHz and the wavelength is 3.53 mm, the interval is at least 0.25 mm (0.07×3.53 mm). The right side of FIG. 7 is a schematic diagram showing the male connector 210 including a male insulating case 212 according to other embodiments of the present invention, and the male insulating case 212 mounts the metal members (including the male terminals 211, the male metal case 213, the first male metal body 214, and the second male metal bodies 215) shown on the left side of FIG. 7.

[0026] Referring to FIG. 8, the left side of FIG. 8 shows a schematic diagram of the metal members of the female connector 220 including a plurality of female terminals 221, a female metal case 223, a first female metal body 224, and a second female metal body 225 according to another embodiment of the present invention. The second female metal body 225 includes a metal sheet 225a and a metal sheet 225b, and the metal sheet 225a and the metal sheet 225b are not connected to each other. In order to obtain a better frequency response, there is a spacing distance of at least 0.07λ, where λ is the wavelength of the aforementioned high-frequency signal. For example, when the operating frequency of the aforementioned high-frequency signal is 50 GHz and the wavelength of the aforementioned high-frequency signal is 3.53 mm, the spacing is at least 0.25 mm (0.07 × 3.53 mm). The right side of FIG. 8 shows a schematic diagram of the female connector 220 including a female insulating case 222 according to another embodiment of the present invention. The female insulating case 222 mounts the metal members (including the female terminals 221, the female metal case 223, the first female metal body 224, and the second female metal body 225) shown on the left side of FIG. 8.

[0027] In the embodiments shown in FIGS. 7 and 8, when the male connector 210 and the female connector 220 are joined to each other, the first male metal body 214 and the first female metal body 224 are joined to each other correspondingly to form the first metal member 140 shown in FIG. 1. The first metal member 140 is exposed from the insulating case 160 of FIG. 1 and is electrically grounded. And these second male metal bodies 215 and these second female metal bodies 225 are joined to each other correspondingly to form a plurality of second metal members 150 shown in FIG. 1. The second metal members 150 are exposed from the insulating case 160 of FIG. 1 and are electrically grounded, thereby realizing the interruption between the joining terminal groups 130 in the first direction D1 and the second direction D2. In summary, without departing from the spirit and technical scope of the present invention, the combination form and the position configuration of the first metal member 140 and the second metal member 150 can be changed and modified.

[0028] The high-frequency connector according to the present invention is suitable for transmitting signals in the high-frequency band (for example, the millimeter-wave band). By using the shielding characteristics and grounding of metal members, losses caused by reflection of transmitted signals, high-frequency resonance, or impedance mismatch can be reduced, and signals can be effectively transmitted even at high frequencies. In summary, the high-frequency connector of the present invention can transmit signals at high frequencies, and by installing metal members, problems such as high-frequency resonance, signal distortion, and noise interference that the connector may encounter at high frequencies can be improved, and the transmission quality can be enhanced.

[0029] As described above, the present invention is disclosed in the embodiments, but these embodiments are not used to limit the present invention. Any person skilled in the art with general knowledge in this technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention is based on what is defined in the appended patent application scope.
