[0048] The present application is a male connector with a metal barrel and a male terminal assembly thereof, which is designed to be applied in connector set C and can be applied to signal or power transmission of electronic devices. First, the basic architecture of the connector set C is introduced. Please refer to FIG. 1A and FIG. 1B The connector set C at least includes a female connector 1 and the male connector 2, wherein the female connector 1 can be connected to a transmission carrier, and the male connector 2 can be connected to another transmission carrier. According to product requirements, the types of the two transmission carriers can be the same or different, and can be a circuit board P or a transmission line L, etc. When the female connector 1 and the male connector 2 are inserted into each other, power and / or signal transmission between the two transmission carriers can be achieved.

[0049] As mentioned above, in an embodiment, please refer to FIG. 1A and FIG. 1B The female connector 1 includes a female insulating body 11 and a female metal shell 13, and is arranged on a circuit board P, and the circuit board P is provided with a plurality of conductive contacts P1; the male connector 2 is connected with a plurality of transmission lines L. Please refer to FIG. 2 The transmission line L is in the form of a coaxial cable, which at least includes a core wire L1, a first insulating layer L2, a metal braid layer L3, and a second insulating layer L4, wherein the core wire L1 is used to transmit electrical signals; the first insulating layer L2 is wrapped outside the core wire L1; the metal braid layer L3 is arranged outside the first insulating layer L2 to provide grounding and shielding functions; and the second insulating layer L4 is wrapped outside the metal braid layer L3. However, in other embodiments of the present application, according to product requirements, the number of transmission lines L can be one or more, and the form of the transmission line L can be other specifications, not limited to the form of a coaxial cable. In addition, the number of conductive contacts P1 can be one or more, and can be the same as or different from the number of each of the transmission lines L.

[0050] The structure and characteristics of the male connector 2 will be described in detail below. For the convenience of describing the characteristics and relative position relationship of the assembly, in the subsequent description, the spatial form of the assembly is defined according to three mutually orthogonal axes, the aforementioned three axes are horizontal axis (X-axis), vertical axis (Y-axis) and vertical axis (Z-axis), specifically, the horizontal axis (X-axis) refers to the left-right extending direction, wherein, FIG. 1B the left upper side of the figure as the left side direction of the assembly, FIG. 1B the right lower side of the figure as the right side direction of the assembly; the vertical axis (Y-axis) refers to the front-back extending direction, wherein, FIG. 1B the left lower side of the figure as the front side direction of the assembly, FIG. 1B the right upper side of the figure as the rear side direction of the assembly; the vertical axis (Z-axis) refers to the up-down extending direction, FIG. 1B the upper side of the figure as the upper (top) side direction of the assembly, FIG. 1Bthe lower (bottom) side of the component.

[0051] As mentioned above, please refer to FIG. 1A to FIG. 4 As shown in FIG. 1, the male connector 2 comprises a male base 21 and at least one connecting terminal 22, wherein the male base 21 is made of insulating material and can be directly or indirectly coated on partial portions of the connecting terminal 22 by injection molding process, insert molding and / or other processes. In this embodiment, the male base 21 comprises a first base body 211 and a second base body 212, wherein the first base body 211 is located below the second base body 212, has a cross-sectional area smaller than that of the second base body 212 and does not cover the transmission line L, and the second base body 212 can cover partial transmission line L and partial connecting terminal 22 at the same time, but is not limited thereto. In other embodiments of the present application, the male base 21 can be composed of a single component or more than three components, wherein the volume and shape of each component used to compose the male base 21 can be determined according to product requirements, and is not limited to the representation form shown in the drawings, and each component can be coated on the connecting terminal 22 by the same process or different processes, so as to improve the flexibility of design and production.

[0052] Herein, the form that the male base 21 directly or indirectly covers the connecting terminal 22 is described. Please refer to FIG. 1A to FIG. 4As shown, in this embodiment, the male connector 2 is further provided with at least one metal cylinder 23, and one or more connecting terminals 22 can be located inside the single metal cylinder 23. In addition, the male base 21 can be covered on the partial outer edge of the metal cylinder 23 by using the injection molding process, embedding or other means. The aforementioned structure is "indirectly" covered on the partial portion of the connecting terminal 22, which means that the male base 21 indirectly contacts the connecting terminal 22 through the metal cylinder 23, without directly contacting the connecting terminal 22. However, in other embodiments of the present application, the male connector 2 can not be provided with the metal cylinder 23, so when the male base 21 directly contacts the partial portion of the connecting terminal 22, it constitutes the structure of "directly" covered on the partial portion of the connecting terminal 22. In this way, when the male connector 2 has multiple connecting terminals 22, the arrangement position of the multiple connecting terminals 22 can be effectively maintained by the design of the male base 21. In addition, the male base 21 can also serve as part of the mating portion of the male connector 2, so as to extend into the mating space of the female connector 1, and can be provided with a male buckle portion 213 (such as a protrusion, but not limited thereto), so as to be combined with the corresponding buckle unit 1322 of the female connector 1, to ensure the stable insertion between the male connector 2 and the female connector 1, and to avoid the positional deviation of the connecting terminal 22 during the insertion process, thereby causing poor contact and other problems. It is particularly pointed out that the aforementioned mating portion generally refers to all components that can extend into the mating space, and is not limited to a specific structure or form; the form of the aforementioned male buckle portion 213 can be changed according to the buckle unit 1322, as long as they can be matched and combined with each other.

[0053] In addition, please refer to FIG. 1A to FIG. 4 As shown, the top end of the connecting terminal 22 is provided with a fixing portion 221, and the bottom end of the connecting terminal 22 is provided with an abutting portion 223. In this embodiment, since the transmission line L is electrically connected to the connecting terminal 22 in the vertically downward direction, please refer to FIG. 5 As shown, the vertical cross-sectional shape of the fixing portion 221 substantially extends in the direction of the vertical axis, so as to be welded to the core wire L1, but not limited thereto. In other embodiments of the present application, the fixing portion 221 can be adjusted to other shapes according to actual needs, and in addition, the position of the fixing portion 221 fixed to the transmission line L can also be adjusted, as long as the fixing portion 221 can be electrically connected to the transmission line L and can transmit power and / or signals.

[0054] As mentioned above, please refer to FIG. 1A to FIG. 4As shown, the abutment portion 223 can abut against the conductive contact P1 of the circuit board P. In this embodiment, since the circuit board P is located on the plane (XY plane) formed by the horizontal axis (X-axis) and the vertical axis (Y-axis), please refer to [further details omitted]. FIG. 5 As shown, the vertical cross-sectional shape of the abutment portion 223 can substantially extend along the horizontal or vertical axis, and its bottom surface can abut against the conductive contact P1 on the circuit board P. Specifically, in the initial state (i.e., when not subjected to downward pressure), the vertical cross-sectional shape of the abutment portion 223 can be horizontal, arc-shaped, or other shapes extending in the left-right or front-back direction; when the abutment portion 223 is subjected to downward pressure, its shape will deform along the flat surface of the conductive contact P1 and abut against the conductive contact P1 to transmit power and / or signals.

[0055] Furthermore, please refer to [the relevant documents / references]. FIG. 1A to FIG. 4 As shown, when the male connector 2 is inserted into the female connector 1, the connection terminal 22 will be subjected to downward pressure to tightly abut against the conductive contact P1, thereby enabling the transmission line L and the circuit board P to achieve stable power and / or signal transmission through the connection terminal 22. Based on this, in order to ensure that the connection terminal 22 has flexible structural adjustment capability and structural stability, the connection terminal 22 of this application includes, but is not limited to, the two structural forms described below.

[0056] First, please refer to FIG. 2 and FIG. 5 As shown, the first structural form is a "coaxial spatial configuration." In terms of geometric relationships, the positions of the fixing part 221 and the abutting part 223 in three-dimensional space allow the same vertical axis z to pass through part of their structure (e.g., FIG. 5 As shown, the fixing part 221 and the abutment part 223 are arranged along the same vertical axis z to form an axially corresponding arrangement. Thus, when the connecting terminal 22 is subjected to external force (downward pressure), the pressure is concentrated in the vertical axis z direction, reducing uneven force distribution and offset, thereby reducing problems such as deformation, breakage, or poor contact of the connecting terminal 22. Furthermore, when the abutment part 223 is deformed by downward pressure (e.g., from an arc shape to a straight shape), because the fixing part 221 and the abutment part 223 are axially arranged supports, the deformation occurs uniformly in the vertical axis z direction, ensuring that the force direction on the connecting terminal 22 is consistent, so that the abutment part 223 can smoothly abut against the conductive contact P1.

[0057] Secondly, the second structural form is "multi-segment structure and projection configuration," please refer to [further details]. FIG. 2 and FIG. 5As shown, the middle section 222 of the connection terminal 22 (i.e. excluding the fixing portion 221 and the rest of the abutting portion 223) is provided with a plurality of bending portions 225 to form a multi-section structure, and the multi-section structure comprises a plurality of extension sections, which in this embodiment comprises a plurality of vertical sections 226 and a plurality of relay abutting sections 227B, wherein each of the vertical sections 226 extends substantially along the vertical axis (Z-axis) direction, and the relay abutting sections 227B are used to link two adjacent vertical sections 226. In a preferred case, the vertical section 226 can be completely parallel to the vertical axis, but in actual production, it is affected by the tolerance or design, as long as the deviation angle θ between the vertical section 226 and the vertical axis of itself is not more than 10 degrees, it is called the vertical section 226 in this application.

[0058] As mentioned above, please refer to FIG. 2 and FIG. 5 As shown, in this embodiment, the fixing portion 221 is directly connected to the uppermost vertical section 226, and the abutting portion 223 is directly connected to the lowermost vertical section 226, wherein the fixing portion 221 and the uppermost vertical section 226 both extend along the same vertical axis z in a straight line, but it is not limited thereto. In a variant embodiment of the present application, please refer to FIG. 6 As shown, between the fixing portion 221 and the uppermost vertical section 226, an upper relay abutting section 227A can be provided; between the abutting portion 223 and the lowermost vertical section 226, a lower relay abutting section 227C can be provided; thus, according to the actual needs of the product, in some embodiments, the connection terminal 22 can not be provided with the upper relay abutting section 227A or the lower relay abutting section 227C, but the fixing portion 221 is directly connected to the vertical section 226, or the abutting portion 223 is directly connected to the vertical section 226; in some embodiments, when the fixing portion 221 and the vertical section 226 are both in a straight line, the part close to the top end can be divided into the fixing portion 221, and the remaining part is the vertical section 226.

[0059] Also, please refer to FIG. 2 and FIG. 7As shown, when the connection terminal 22 is provided with two or more vertical segments 226, among all the vertical segments 226, the two vertical segments 226 with the most distant horizontal positions can form a projection range V, and the fixed portion 221 is completely located in the projection range V (including the edge of the projection range V). It is particularly pointed out that the aforementioned projection range V refers to the range formed between the two vertical segments 226 with the most distant horizontal positions. Thus, since the fixed portion 221 is located in the projection range V, the downward pressure transmitted by the fixed portion 221 can be gradually transmitted to the abutting portion 223 through each extension segment of the multi-segment structure, so that the pressure is gradually dispersed in the intermediate segment 222, effectively avoiding stress concentration in a single area, thereby improving the durability and stability of the structure. In the embodiment, the abutting portion 223 can also be located in the projection range V, so that the pressure direction of the connection terminal 22 remains consistent, but this is not limited thereto.

[0060] In addition, referring to FIGS. 1A and 1B, FIG. 2 and FIG. 5 to FIG. 7 As shown, through the design of the vertical segment 226 and the plurality of receiving segments 227 (including the upper receiving segment 227A, the relay receiving segment 227B, and / or the lower receiving segment 227C), the connection terminal 22 can have rigidity and elasticity, and can achieve the functions of buffering and pressure absorption. The vertical segment 226 can provide higher rigidity and accurate pressure transmission direction, effectively reducing energy loss caused by change of force direction, and the receiving segment 227 is responsible for smooth transition and absorption of pressure, further improving the mechanical properties of the structure, preventing improper deformation or damage of the connection terminal 22. However, in other embodiments of the present application, the vertical segment 226 can be omitted and various shapes of extension segments such as arc or inclined straight line (i.e., not extending along the vertical axis (Z axis)) can be used, as long as the projection range formed between the two extension segments with the most distant horizontal positions among the plurality of extension segments included in the multi-segment structure can correspond to the fixed portion 221. It is particularly pointed out that according to the actual needs of the product, the connection terminal 22 can simultaneously have the structure of “coaxial space configuration” and “multi-segment structure and projection configuration”, or can only have “coaxial space configuration” or “multi-segment structure and projection configuration”.

[0061] In addition, referring to FIGS. 1A and 1B, FIG. 1A to FIG. 3As shown, in this embodiment, the connecting terminal 22 and the metal cylinder 23 can serve as a male terminal assembly, and the connecting terminal 22, the metal cylinder 23, and the transmission line L can serve as a male transmission assembly. When the connecting terminal 22 is housed within the metal cylinder 23, especially in high-frequency applications, the aforementioned architecture can effectively shield external electromagnetic interference through the metal cylinder 23, protecting the signal transmission of the internal connecting terminal 22. Simultaneously, it can prevent the signal from the connecting terminal 22 from radiating to the external environment, ensuring compliance with electromagnetic compatibility requirements. Furthermore, the metal cylinder 23 has superior protective properties, providing excellent protection for the connecting terminal 22 and extending its service life. However, in actual production, because the connecting terminal 22 is relatively long and needs to be fixed to the transmission line L, to improve production or assembly convenience, in this embodiment, please refer to... FIG. 4 As shown, the metal cylinder 23 can include an upper cylinder assembly 231 and a lower cylinder assembly 232. The upper cylinder assembly 231 has an upper cylinder space 2310, and the lower cylinder assembly 232 has a lower cylinder space 2320. The upper cylinder assembly 231 and the lower cylinder assembly 232 can be connected and are arranged vertically in an up-down configuration, such that the upper cylinder assembly 231 is in the upper position and the lower cylinder assembly 232 is in the lower position. At the same time, the upper cylinder space 2310 and the lower cylinder space 2320 are connected to form a cylinder space 230.

[0062] Please refer to the above. FIG. 1A to FIG. 4 As shown, in this embodiment, the two connecting terminals 22 can be located within the cylindrical space 230 without contacting the metal cylinder 23, but this is not a limitation. Depending on product requirements, the metal cylinder 23 can accommodate one or more connecting terminals 22. Furthermore, when the connecting terminal 22 is located within the metal cylinder 23, and the contact portion 223 has not yet contacted the conductive contact P1, please refer to... FIG. 8AAs shown, the horizontal height H1 of the bottom surface of the abutting portion 223 is lower than the horizontal height H2 of the bottom surface of the lower barrel assembly 232, in other words, the bottom end of the connection terminal 22 protrudes beyond the bottom end of the lower barrel assembly 232 in side view. Thus, due to the elasticity of the connection terminal 22 itself, after the abutting portion 223 abuts against the conductive contact P1, the abutting portion 223 can retract into the barrel space 230, so that the abutting portion 223 and the conductive contact P1 can be tightly abutted. However, in other embodiments of the present application, according to product requirements, the horizontal height H1 of the bottom surface of the abutting portion 223 can be flush with the horizontal height H2 of the bottom surface of the lower barrel assembly 232, so that the abutting portion 223 can abut against the conductive contact P1 without being blocked by the lower barrel assembly 232. In addition, in some embodiments, when the female connector 1 has a female terminal, the abutting portion 223 can also contact the female terminal, in other words, the abutting portion 223 is not limited to abutting against the conductive contact P1, but can include contacting various forms of electrical connections (such as the conductive contact P1 or the female terminal, etc.).

[0063] In addition, please refer to FIG. 1A to FIG. 4 As shown, in this embodiment, the upper barrel assembly 231 can be fixed to the transmission line L, and the upper barrel space 2310 can correspond to the fixed portion 221 of the connection terminal 22 and the core wire L1 of the transmission line L. Therefore, in order to facilitate observation and processing of the connection relationship between the fixed portion 221 and the core wire L1, the height (up-down direction) of the upper barrel assembly 231 can be less than the height (up-down direction) of the lower barrel assembly 232, but not limited thereto. In some embodiments, if the upper barrel assembly 231 needs to be additionally provided with other structures or components, the height of the upper barrel assembly 231 can be the same as or greater than the height of the lower barrel assembly 232, so as to improve the flexibility of production and design.

[0064] In addition, please refer to FIG. 9As shown, in this embodiment, the inner diameter width of the upper cylinder assembly 231 can be greater than or equal to the outer diameter width of the lower cylinder assembly 232, so that the top end of the lower cylinder assembly 232 can extend into the upper cylinder assembly 231, and thus the lower cylinder assembly 232 and the upper cylinder assembly 231 partially overlap each other. In order to achieve a reliable assembly relationship, the upper cylinder assembly 231 is provided with an upper positioning portion 2311, and the lower cylinder assembly 232 is provided with a lower positioning portion 2321, wherein the upper positioning portion 2311 is an inwardly protruding protrusion, and the lower positioning portion 2321 is an inwardly recessed recess, which can be matched and combined to stably assemble the upper cylinder assembly 231 and the lower cylinder assembly 232 to each other, but not limited thereto. In other embodiments of the present application, the upper cylinder assembly 231 and the lower cylinder assembly 232 can be combined in a tight fit manner; or the upper cylinder assembly 231 and the lower cylinder assembly 232 are combined by welding; or the upper cylinder assembly 231 and the lower cylinder assembly 232 are combined by laser welding. In addition, in order to maintain the expected assembly position of the upper cylinder assembly 231 and the lower cylinder assembly 232, the lower cylinder assembly 232 can protrude at least one limiting portion 2323, and the top end of the lower cylinder assembly 232 can extend into the upper cylinder assembly 231 until the bottom edge of the upper cylinder assembly 231 abuts against the limiting portion 2323. In this way, the lower cylinder assembly 232 can be prevented from excessively extending into the upper cylinder assembly 231.

[0065] In the foregoing embodiments, the metal cylinder is a multi-piece cylinder assembly structure. However, according to product design requirements, in a variant embodiment, the metal cylinder can be designed as a single cylinder, and the internal cylinder space can be divided into an upper cylinder space and a lower cylinder space. The upper cylinder space is used to accommodate the fixed portion of the connection terminal, and the lower cylinder space is used to accommodate the remaining portion of the connection terminal. The width of the upper cylinder space in the horizontal or vertical direction is greater than the width of the lower cylinder space in the horizontal or vertical direction. In this way, the wider structure design of the upper cylinder space can increase the operation space, facilitate the assembly, welding or other process operations between the connection terminal and the transmission line, and effectively reduce the heat accumulation between the connection terminal and the transmission line, thereby improving the thermal stability of the structure.

[0066] In another variant, the metal cylinder can be divided into an upper cylinder portion and a lower cylinder portion. The upper cylinder portion can accommodate the fixed portion of the connection terminal, and the lower cylinder portion can accommodate the remaining portion of the connection terminal. The width of the upper cylinder portion in the horizontal or vertical direction is greater than the width of the lower cylinder portion in the horizontal or vertical direction, so as to form a configuration in which the upper portion is wider than the lower portion. In this way, when the male connector is provided with multiple metal cylinders, the distance between the upper portions of adjacent metal cylinders can be less than the distance between the lower portions of adjacent metal cylinders. In other words, the regions of adjacent metal cylinders near the top end are closer to each other, and the regions of adjacent metal cylinders near the bottom end are farther away from each other. Since the connection between the transmission terminal and the transmission line is usually a sensitive area for interference, the aforementioned structure can form a tighter metal shielding layer in the upper portion (i.e., the region of the metal cylinder near the top end) to provide a stronger shielding effect, effectively reducing electromagnetic interference (EMI) and improving the integrity and stability of the transmission signal.

[0067] The aforementioned two variants are equivalent to integrally forming the upper cylinder assembly 231 and the lower cylinder assembly 232 of FIG. 4 to form a single assembly while retaining some features of the multi-piece structure. Specifically, in this variant, the upper cylinder space and the lower cylinder space in the single cylinder correspond to the upper cylinder space 2310 and the lower cylinder space 2320 provided in the upper cylinder assembly 231 and the lower cylinder assembly 232 of FIG. 4 In another variant, the upper cylinder portion and the lower cylinder portion in the single cylinder correspond to the upper cylinder assembly 231 and the lower cylinder assembly 232 of FIG. 4 Therefore, the multiple embodiments described above can achieve equivalent or similar technical functions and meet different product or production requirements.

[0068] In addition, to enhance the stability between the metal cylinder 23 and the male base 21, at least one side surface of the metal cylinder 23 can be provided with a coupling portion for connecting to the male base 21, so that the metal cylinder 23 and the male base 21 can be tightly coupled. Specifically, taking the structure of the coupling portion as a through hole as an example, in this embodiment, please refer to FIG. 8A to FIG. 8CAs shown, one side (e.g., the right side) of the metal cylinder 23 is provided with a first through hole 233, and the first through hole 233 corresponds to a portion of the connecting terminal 22; the other side (e.g., the left side) of the metal cylinder 23 is provided with a second through hole 234. In this embodiment, since the lower cylinder assembly 232 is relatively long, the first through hole 233 and the second through hole 234 can be provided on the lower cylinder assembly 232, but are not limited thereto. Thus, by means of the structure of the first through hole 233 and the second through hole 234, when the male end base 21 or the second base body 212 is fixed to the metal cylinder 23 by injection molding, the male end base 21 or the second base body 212 can cover the first through hole 233 and / or the second through hole 234, and a portion of it can extend into the first through hole 233 and / or the second through hole 234, so that the metal cylinder 23 and the male end base 21 can be tightly connected.

[0069] Also, please refer to [the relevant document / reference]. FIG. 8A to FIG. 8C As shown, in this embodiment, the first through hole 233 and the second through hole 234 are located on opposite sides and are not directly opposite each other. This avoids the risk of local structural weakening of the metal cylinder 23 due to the first through hole 233 and the second through hole 234 being too close together. However, depending on the actual needs of the product, the following variations are also possible:

[0070] (1) The metal cylinder 23 can be provided with a plurality of first through holes 233 or a plurality of second through holes 234, and each

[0071] The size and shape of the first through hole 233 or the second through hole 234 may be the same or different.

[0072] (2) The metal cylinder 23 can have a first through hole 233 on only one side.

[0073] (3) When the metal cylinder 23 has a plurality of first through holes 233 and a plurality of second through holes 234, at least one first through hole 233 and at least one second through hole 234 may be opposite to each other or not opposite to each other, as described above.

[0074] "Relative" means that when the first through hole 233 and the second through hole 234 are on opposite sides, their extended projection areas at least partially overlap; the aforementioned "non-relative" means that the extended projection areas of the first through hole 233 and the second through hole 234 do not overlap at all, or that the two are located on non-relative sides respectively.

[0075] (4) When the male connector 2 is provided with multiple metal cylinders 23, the sides of two adjacent metal cylinders 23 with joints face each other, but the aforementioned joints of the two are not facing each other; FIG. 9 For example, located in FIG. 9 The right side of the metal cylinder 23 on the left side is provided with a first through hole 233, located inFIG. 9 The left side of the metal cylinder 23 on the right is provided with a second through hole 234. The first through hole 233 and the second through hole 234 have no overlapping area in the horizontal projection direction (they are not opposite each other); it should be noted here that, although FIG. 9 Each of the two metal cylinders 23 has two connecting portions (a first through hole 233 and a second through hole 234), but this is not a limitation. In some embodiments, different metal cylinders 23 may have only a single connecting portion, and the position and configuration may be different. In other words, the two connecting portions located at... FIG. 9 The metal cylinder 23 on the left side can be provided with only the first through hole 233 on the right side, located in FIG. 9 The right-hand metal cylinder 23 may only have a second through hole 234 on its left side. Therefore, the naming of the first through hole 233 and the second through hole 234 is merely to distinguish the joints on different sides of the same metal cylinder 23. For different metal cylinders 23, unless otherwise specified, the first through hole 233 can be located on different sides. Thus, although the opposite sides of two adjacent metal cylinders 23 each have through holes, their positions are not opposite. Therefore, the exposed portion of the connecting terminal 22 located within different metal cylinders 23 is still shielded by the cylinder wall of the adjacent metal cylinder 23, effectively reducing interference coupling between high-frequency signals, further improving crosstalk interference, and thus enhancing the integrity of signal transmission.

[0076] (5) When the male connector 2 is provided with multiple metal cylinders 23, the multiple metal cylinders 23 can form two rows of metal cylinder groups, and the multiple metal cylinders 23 in each row of metal cylinder groups are arranged along the same reference direction. For example, as FIG. 3 and FIG. 10 As shown, the two rows of metal grounding cylinders are arranged along the longitudinal axis (Y-axis).

[0077] The metal cylinders 23 in each row of the metal grounding cylinder group are arranged in a directional manner, and are distributed along the horizontal axis (X-axis). Furthermore, the first through holes 233 on the same side (e.g., the right side) of two adjacent metal cylinders 23 in different rows have different horizontal heights H3 and H4 at their bottom edges. It should be specifically noted that the aforementioned "same side" refers to the side corresponding to the same direction in a three-dimensional coordinate system when each of the metal cylinders 23 is installed on the male connector 2.

[0078] In addition to the through-hole structure of the joint, in a modified embodiment, the joint can be a protrusion, and its number and position can vary as described above for the first through-hole 233 and the second through-hole 234. For ease of explanation, only different components will be labeled thereafter; other identical components will retain their original component labels and will not be described in detail. For specific details, please refer to... FIG. 11A to FIG. 11CAs shown, one side (e.g. front side) of the metal cylinder 23 is provided with a first protrusion 233', which is formed by cutting or punching a partial region of the metal cylinder 23 into a piece, and then tilting the piece outwardly to partially protrude from the front side of the metal cylinder 23. The other side (e.g. back side) of the metal cylinder 23 is provided with a second protrusion 234', which is formed in the same manner as the first protrusion 233'. In this way, the metal cylinder 23 and the male base 21 can be stably combined by the first and second protrusions 233' and 234'. In addition, in some embodiments, the male base 21 or a part thereof (e.g. the second base 212) can be made of metal and combined with the metal cylinder 23 by snap-in, to provide a grounding path and electromagnetic shielding effect, without being limited to using insulating materials and injection molding process.

[0079] Furthermore, in order to stably assemble the connection terminal 22 into the metal cylinder 23 and keep it in the desired position, in this embodiment, please refer to FIG. 2 to FIG. 4 As shown, at least one connection terminal 22 can be fixed to a terminal seat 24, and the terminal seat 24 does not cover the fixing portion 221 of the connection terminal 22, so that the fixing condition between the connection terminal 22 and the transmission line L can be easily connected or observed in the subsequent process (but not limited thereto), and then the terminal seat 24 can be assembled into the metal cylinder 23 together with the connection terminal 22 thereon. Specifically, the terminal seat 24 is provided with an upper seat mounting groove 241 and a lower seat mounting groove 242. The upper seat mounting groove 241 is recessed downwardly from the top surface of the terminal seat 24 and forms an opening on one side (e.g. front, back, left or right side) of the terminal seat 24, as shown in the front view, the upper seat mounting groove 241 is recessed inwardly from the front side of the terminal seat 24. FIG. 4 As shown, the lower seat mounting groove 242 is recessed upwardly from the bottom surface of the terminal seat 24 and forms an opening on one side (e.g. front, back, left or right side) of the terminal seat 24, as shown in the front view, the lower seat mounting groove 242 is recessed inwardly from the front side of the terminal seat 24. FIG. 4 As shown, the lower seat mounting groove 242 is recessed upwardly from the bottom surface of the terminal seat 24 and forms an opening on one side (e.g. front, back, left or right side) of the terminal seat 24, as shown in the front view, the lower seat mounting groove 242 is recessed inwardly from the front side of the terminal seat 24.

[0080] As shown, the lower seat mounting groove 242 is recessed upwardly from the bottom surface of the terminal seat 24 and forms an opening on one side (e.g. front, back, left or right side) of the terminal seat 24, as shown in the front view, the lower seat mounting groove 242 is recessed inwardly from the front side of the terminal seat 24. FIG. 2 to FIG. 4 , FIG. 12As shown, the metal cylinder 23 is provided with a first cylinder mounting portion 236 and a second cylinder mounting portion 237. In this embodiment, the lower cylinder assembly 232 is provided with the first cylinder mounting portion 236 and the second cylinder mounting portion 237. The first cylinder mounting portion 236 is a spring sheet formed by shearing or punching a partial region of the lower cylinder assembly 232 and extending toward the lower cylinder space 2320. The second cylinder mounting portion 237 is a protruding piece formed by punching a partial region of the lower cylinder assembly 232 inward. When the terminal seat 24 is mounted into the metal cylinder 23 from top to bottom, the free end of the spring sheet (the first cylinder mounting portion 236) first extends into the lower seat mounting groove 242, is deformed and compressed by the blocking of the spacing wall 243 between the upper seat mounting groove 241 and the lower seat mounting groove 242, and is embedded into the upper seat mounting groove 241 after passing the spacing wall 243, and can abut against the groove wall of the upper seat mounting groove 241 adjacent to the spacing wall 243 (as shown in FIG. 12 As shown, the metal cylinder 23 is provided with a first cylinder mounting portion 236 and a second cylinder mounting portion 237.

[0081] In order to make the metal cylinder 23 have good grounding effect and anti-electromagnetic interference ability, please refer to FIG. 2 to FIG. 4As shown, the upper cylinder assembly 231 has at least one contact portion 2313, and the contact portion 2313 can directly contact the metal braided mesh layer L3 to provide a stable grounding path. Depending on product or production requirements, the contact portion 2313 can be integrally formed into the upper cylinder assembly 231, or the contact portion 2313 can be an independent component that can be assembled into the upper cylinder assembly 231. Various embodiments of the contact portion 2313 will be described here. In a first embodiment, the contact portion 2313 is an elongated strip extending upwards from the top edge of one side (e.g., the rear side) of the upper cylinder assembly 231. However, in other embodiments of this application, the upper cylinder assembly 231 can have multiple contact portions 2313 located on different sides. Furthermore, the free section of the elongated strip (e.g., the...) FIG. 4 and FIG. 8A The area near the top can be bent inwards, allowing its inner surface to be directly connected to the metal braided mesh layer L3 (such as...). FIG. 2 (As shown), they are electrically connected to each other. In this first embodiment, the highest horizontal height H5 of the free section of the elongated sheet (contact portion 2313) exceeds the horizontal height H6 of the top of the upper cylinder assembly 231.

[0082] In the second implementation, please refer to FIG. 13A and FIG. 13B As shown, the upper cylinder assembly 231 has contact portions 2313 on two opposite sides (e.g., the front and rear sides). However, in other embodiments of this application, contact portions 2313 can be provided on any two sides, or only on one side. Furthermore, the contact portion 2313 is also a long strip and has the bending features and connection relationship as in the first embodiment (the inner surface is directly connected to...). FIG. 2 The metal woven mesh layer L3), the contact portion 2313 differs from the first embodiment in that the highest horizontal height H7 of the free section of the long strip (contact portion 2313) does not exceed the horizontal height H8 of the top of the upper cylinder assembly 231. In other words, the four top edges of the upper cylinder assembly 231 are not at the same horizontal height, and the contact portion 2313 is provided on the top edge of the side at the lower horizontal height.

[0083] In the third implementation, please refer to FIG. 14A and FIG. 14B As shown, the upper cylinder assembly 231 has contact portions 2313 on two opposite sides (e.g., the front and rear sides).

Furthermore, the contact portion 2313 is also a long strip and has the bending features and connection relationship as in the first embodiment (the inner surface is directly connected to...). FIG. 2The metal woven mesh layer L3), the contact portion 2313 differs from the first embodiment in that the long strip is separated from the middle section of the side of the upper cylinder assembly 231. In other words, the contact portion 2313 is not extended from the top edge of the upper cylinder assembly 231.

[0084] In the fourth implementation, please refer to FIG. 15A and FIG. 15B As shown, the upper cylinder assembly 231 has a contact portion 2313 on one side (e.g., the front side).

Furthermore, the contact portion 2313 is a long strip, but unlike the first embodiment, its free section can be bent into an arc shape. Viewed in a vertical cross-section, the aforementioned arc shape is an inverted U-shape. Therefore, the long strip (the contact portion 2313) is directly connected to the metal braided mesh layer L3 from its outer side. It should be noted that the outer and inner sides of the contact portion 2313 refer to opposite sides. Before the long strip is bent, it faces away from the upper cylinder space 2310 (e.g., the front side). FIG. 4 The side shown is the "outer side", while the side facing the upper cylinder space 2310 is the "inner side". In this fourth embodiment, the highest horizontal height H9 of the free section of the elongated sheet (contact portion 2313) exceeds the horizontal height H10 of the top of the upper cylinder assembly 231.

Furthermore, the contact portion 2313 is also a long strip and has an arc-shaped configuration and connection relationship as in the fourth embodiment (the outer surface is directly connected to...). FIG. 15B The metal woven mesh layer L3), the contact portion 2313 differs from the fourth embodiment in that the highest horizontal height H9 of the free section of the elongated sheet (contact portion 2313) does not exceed the horizontal height H10 of the top of the upper cylinder assembly 231. Furthermore, the contact portion 2313 in the sixth embodiment, like in the third embodiment, can also be formed by separating a localized area of ​​the middle section of one side of the upper cylinder assembly 231 to serve as the contact portion 2313.
