[0052] This application discloses a male connector with a reinforced bonding structure and its male terminal assembly, designed for use in connector group C and applicable to signal or power transmission in electronic devices. The basic architecture of connector group C is described below. Please refer to... Figure 1A and Figure 1B As shown, the connector group C includes at least one female connector 1 and one male connector 2. The female connector 1 can be connected to one transmission carrier, and the male connector 2 can be connected to another transmission carrier. Depending on product requirements, the two transmission carriers can be the same or different, and can be circuit boards P or transmission lines L, etc. When the female connector 1 and the male connector 2 are plugged into each other, power and / or signal transmission between the two transmission carriers can be realized.

[0053] As above, in one embodiment, please refer again to Figure 1A and Figure 1B As shown, the female connector 1 includes a female insulating body 11 and a female metal housing 13, and is disposed on a circuit board P, which has multiple conductive contacts P1; the male connector 2 is connected to a plurality of transmission lines L, please refer to [reference needed]. Figure 2 As shown, the transmission line L is in the form of a coaxial cable, comprising at least one core wire L1, a first insulating layer L2, a metal braided mesh layer L3, and a second insulating layer L4. The core wire L1 is used to transmit electrical signals; the first insulating layer L2 covers the core wire L1; the metal braided mesh layer L3 is disposed outside the first insulating layer L2 to provide grounding and shielding functions; and the second insulating layer L4 covers the metal braided mesh layer L3. However, in other embodiments of this application, depending on 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. Furthermore, the number of conductive contacts P1 can be one or more, and can be the same as or different from the number of each transmission line L.

[0054] The structure and features of the male connector 2 will be described in detail below. To facilitate the explanation of component features and relative positional relationships, the spatial form of the component will be defined according to three mutually orthogonal axes in the following description. These three axes are the horizontal axis (X-axis), the vertical axis (Y-axis), and the vertical axis (Z-axis). Specifically, the horizontal axis (X-axis) refers to the left-right extension direction. Figure 1B The upper left corner is used as the left side direction of the component. Figure 1B The lower right of the axis is defined as the right side of the component; the vertical axis (Y-axis) refers to the forward and backward extension direction, where... Figure 1B The lower left corner serves as the front direction of the component. Figure 1B The upper right of the axis is considered the rear direction of the component; the vertical axis (Z-axis) refers to the vertical extension direction. Figure 1B The area above is considered the top (top) side of the component. Figure 1BThe area below is used as the bottom (bottom) side direction of the component.

[0055] Please refer to the above. Figures 1A to 4 As shown, the male connector 2 includes a male base 21 and at least one connecting terminal 22. The male base 21 is made of insulating material and can be directly or indirectly covered by a portion of the connecting terminal 22 using injection molding, insert and / or other processes. Furthermore, in this embodiment, the male terminal base 21 includes a first base body 211 and a second base body 212. The first base body 211 is located below the second base body 212, and its cross-sectional area is smaller than that of the second base body 212. It does not cover the transmission line L, while the second base body 212 can cover part of the transmission line L and part of the connection terminal 22. However, this is not a limitation. In other embodiments of this application, the male terminal base 21 can be composed of a single component or three or more components. The volume and shape of each component used to compose the male terminal base 21 can be determined according to product requirements and are not limited to the form shown in the drawing. Each component can be covered on the connection terminal 22 using the same process or using different processes to cover the connection terminal 22, thereby improving design and production flexibility.

[0056] The form in which the male base 21 "directly or indirectly" covers the connecting terminal 22 will be explained here. Please refer to [further details]. Figures 1A to 4As shown, in this embodiment, the male connector 2 further includes at least one metal cylinder 23, and one or more connecting terminals 22 can be located inside a single metal cylinder 23. Furthermore, the male base 21 can be formed by injection molding, embedding, or other methods to cover a portion of the outer edge of the metal cylinder 23. This structural form is described as "the male base 21 'indirectly' covers a portion of the connecting terminal 22," meaning 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 this application, the male connector 2 may not include the metal cylinder 23. Therefore, when the male base 21 directly contacts a portion of the connecting terminal 22, it constitutes a structural form of "the male base 21 'directly' covers a portion of the connecting terminal 22." Thus, when the male connector 2 has multiple connecting terminals 22, the design of the male base 21 effectively maintains the arrangement of the multiple connecting terminals 22. Furthermore, the male terminal base 21 can also serve as part of the mating portion of the male connector 2, allowing it to extend into the mating space of the female connector 1. It can also be equipped with a male terminal latching portion 213 (e.g., a protrusion, but not limited thereto) to engage with the corresponding latching unit 1322 of the female connector 1, ensuring a stable connection between the male connector 2 and the female connector 1 and preventing problems such as poor contact caused by misalignment of the connecting terminals 22 during the mating process. It should be specifically noted that the aforementioned mating portion 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 terminal latching portion 213 can be changed along with the latching unit 1322, as long as the two can match and engage with each other.

[0057] Additionally, please refer to Figures 1A to 4 As shown, the top end of the connection terminal 22 has a fixing part 221, and the bottom end of the connection terminal 22 has an abutting part 223. The fixing part 221 can be fixed to the core wire L1 of the transmission line L. In this embodiment, since the transmission line L is electrically connected to the connection terminal 22 in a vertical direction, please refer to... Figure 5 As shown, the vertical cross-sectional shape of the fixing part 221 extends substantially along the vertical axis to facilitate welding to the core wire L1, but is not limited thereto. In other embodiments of this application, the fixing part 221 can be adjusted to other shapes as needed. Furthermore, as the form of the transmission line L changes, the position of the fixing part 221 fixed to the transmission line L can also be adjusted, as long as the fixing part 221 can be electrically connected to the transmission line L and can transmit power and / or signals.

[0058] Please refer to the above. Figures 1A to 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]. Figure 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.

[0059] Furthermore, please refer to [the relevant documents / references]. Figures 1A to 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.

[0060] First, please refer to Figure 2 and Figure 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., Figure 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.

[0061] Secondly, the second structural form is "multi-segment structure and projection configuration," please refer to [further details]. Figure 2 and Figure 5As shown, the middle section 222 of the connecting terminal 22 (i.e., the portion excluding the fixing part 221 and the abutment part 223) has multiple bends 225 to form a multi-segment structure, which includes multiple extension segments. In this embodiment, the multiple extension segments include multiple vertical segments 226 and multiple intermediate connecting segments 227B. Each vertical segment 226 extends substantially along the vertical axis (Z-axis), and the intermediate connecting segment 227B is used to connect two adjacent vertical segments 226. In a preferred case, the vertical segment 226 can be completely parallel to the vertical axis, but in actual production, it is affected by tolerances or design. As long as the deviation angle θ between the vertical segment 226 and its own vertical axis does not exceed 10 degrees, it belongs to the vertical segment 226 referred to in this application.

[0062] Please refer to the above. Figure 2 and Figure 5 As shown, in this embodiment, the fixing part 221 is directly connected to the uppermost vertical segment 226, and the abutting part 223 is directly connected to the lowermost vertical segment 226. Both the fixing part 221 and the uppermost vertical segment 226 extend along the same vertical axis z in a straight line, but this is not a limitation. In a modified embodiment of this application, please refer to... Figure 6 As shown, an upper receiving section 227A can be provided between the fixing part 221 and the uppermost vertical section 226; a lower receiving section 227C can be provided between the abutting part 223 and the lowermost vertical section 226. Therefore, according to the actual needs of the product, in some embodiments, the connecting terminal 22 may not have an upper receiving section 227A or a lower receiving section 227C, but the fixing part 221 can be directly connected to the vertical section 226, or the abutting part 223 can be directly connected to the vertical section 226. In some embodiments, when both the fixing part 221 and the vertical section 226 are straight, the part near the top can be divided into the fixing part 221, and the remaining part is the vertical section 226.

[0063] Also, please see Figure 2 and Figure 7As shown, when the connecting terminal 22 has two or more vertical segments 226, the two vertical segments 226 that are furthest apart horizontally can form a projection range V between each other, and the fixing part 221 will be completely within the projection range V (including the edge of the projection range V). It should be noted that the aforementioned projection range V refers to the range formed between the two horizontally furthest parts of the two vertical segments 226. Thus, since the fixing part 221 is within the projection range V, the downward pressure transmitted by the fixing part 221 can be gradually transmitted through the various extensions of the multi-segment structure to the abutment part 223, causing the pressure to be gradually dispersed within the middle section 222, effectively avoiding stress concentration in a single area, thereby improving the durability and stability of the structure. In this embodiment, the abutment part 223 can also be within the projection range V, so that the pressure direction of the connecting terminal 22 remains consistent, but this is not a limitation.

[0064] In addition, please refer to Figure 2 and Figures 5 to 7 As shown, the design of the vertical segment 226 and multiple receiving segments 227 (including the upper receiving segment 227A, the middle receiving segment 227B, and / or the lower receiving segment 227C) enables the connecting terminal 22 to possess both rigidity and elasticity, achieving buffering and pressure absorption functions. The vertical segment 226 provides high rigidity and precise pressure transmission direction, effectively reducing energy loss caused by changes in force direction. The receiving segments 227 are responsible for the smooth transition and absorption of pressure, further improving the mechanical performance of the structure and preventing improper deformation or damage to the connecting terminal 22. However, in other embodiments of this application, the vertical segment 226 can be omitted, and various shapes of extension segments, such as arcs or oblique straight lines (i.e., not extending along the vertical axis (Z-axis) direction), can be used, as long as the projection range formed by the two horizontally furthest extension segments in the multi-segment structure corresponds to the fixing part 221. It is worth mentioning that, depending on the actual needs of the product, the connection terminal 22 can have both a "coaxial spatial configuration" and a "multi-segment structure and projection configuration", or it can have only a "coaxial spatial configuration" or a "multi-segment structure and projection configuration".

[0065] Additionally, please refer to Figures 1A to 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... Figure 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.

[0066] Please refer to the above. Figures 1A to 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... Figure 8AAs shown, the horizontal height H1 of the bottom surface of the abutment portion 223 is lower than the horizontal height H2 of the bottom surface of the lower cylinder assembly 232. In other words, viewed from the side, the bottom end of the connecting terminal 22 extends beyond the bottom end of the lower cylinder assembly 232. Thus, because the connecting terminal 22 itself is elastic, after the abutment portion 223 abuts against the conductive contact P1, it can retract into the cylinder space 230, allowing the abutment portion 223 and the conductive contact P1 to fit tightly together. However, in other embodiments of this application, depending on product requirements, the horizontal height H1 of the bottom surface of the abutment portion 223 can be flush with the horizontal height H2 of the bottom surface of the lower cylinder assembly 232, allowing the abutment portion 223 to abut against the conductive contact P1 without being obstructed by the lower cylinder assembly 232. Furthermore, in some embodiments, when the female connector 1 is in the form of having a female terminal, the abutment portion 223 can also contact the female terminal. In other words, the abutment portion 223 is not limited to abutting against the conductive contact P1, but can include contact with various forms of electrical connectors (such as conductive contact P1 or female terminal).

[0067] Additionally, please refer to Figures 1A to 4 As shown, in this embodiment, the upper cylinder assembly 231 can be fixed to the transmission line L, and the upper cylinder space 2310 can correspond to the fixing part 221 of the connecting 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 fixing part 221 and the core wire L1, the height (vertical direction) of the upper cylinder assembly 231 can be less than the height (vertical direction) of the lower cylinder assembly 232, but this is not a limitation. In some embodiments, if the upper cylinder assembly 231 needs to be additionally equipped with other structures or components, the height of the upper cylinder assembly 231 can be the same as or greater than the height of the lower cylinder assembly 232 to improve the flexibility of production and design.

[0068] Furthermore, please refer to Figure 9As shown, in this embodiment, the inner diameter of the upper cylinder assembly 231 is greater than or equal to the outer diameter of the lower cylinder assembly 232, allowing the top end of the lower cylinder assembly 232 to extend into the upper cylinder assembly 231, thereby causing a partial overlap between the lower cylinder assembly 232 and the upper cylinder assembly 231. Furthermore, to achieve a reliable assembly relationship, the upper cylinder assembly 231 is provided with an upper positioning part 2311, and the lower cylinder assembly 232 is provided with a lower positioning part 2321. The upper positioning part 2311 is an inwardly protruding point, and the lower positioning part 2321 is an inwardly recessed cavity. The two parts can be matched and combined to ensure stable assembly of the upper cylinder assembly 231 and the lower cylinder assembly 232, but this is not a limitation. In other embodiments of this application, the upper cylinder assembly 231 and the lower cylinder assembly 232 can be joined by a tight fit; or, the upper cylinder assembly 231 and the lower cylinder assembly 232 can be joined by welding; or, the upper cylinder assembly 231 and the lower cylinder assembly 232 have no overlapping area and are joined together by laser welding. Furthermore, to maintain the intended assembly position of the upper cylinder assembly 231 and the lower cylinder assembly 232, the lower cylinder assembly 232 can have at least one protruding 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. This prevents the lower cylinder assembly 232 from excessively extending into the upper cylinder assembly 231.

[0069] In the foregoing embodiments, the metal cylinder is a multi-piece cylinder assembly structure. However, according to product design requirements, in a modified embodiment, the metal cylinder can be designed as a single cylinder, with its internal space divided into an upper cylinder space and a lower cylinder space. The upper cylinder space is used to accommodate the fixing part of the connecting terminal, while the lower cylinder space can accommodate the remaining part of the connecting terminal. Furthermore, 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. This wider upper cylinder space design increases the operating space, facilitating assembly, welding, or other processes between the connecting terminal and the transmission line. Simultaneously, it effectively reduces heat accumulation between the connecting terminal and the transmission line, improving the thermal stability of the structure.

[0070] Continuing from the above, in another modified embodiment, the metal cylinder can be divided into an upper cylinder and a lower cylinder. The upper cylinder can accommodate the fixing part of the connecting terminal, while the lower cylinder can accommodate the remaining part of the connecting terminal. The width of the upper cylinder in the horizontal or vertical direction is greater than the width of the lower cylinder in the same direction, forming a configuration that is wider at the top and narrower at the bottom. Thus, when the male connector has multiple metal cylinders, the distance between the upper cylinders of two adjacent metal cylinders can be less than the distance between their lower cylinders. In other words, the areas near the top of two adjacent metal cylinders will be closer together, while the areas near the bottom of two adjacent metal cylinders will be farther apart. Since the connection point between the transmission terminal and the transmission line is usually an interference-sensitive area, the aforementioned structure allows the upper cylinder (i.e., the area near the top of the metal cylinder) to form a denser metal shielding layer, providing a stronger shielding effect, effectively reducing electromagnetic interference (EMI), and thereby improving the integrity and stability of the transmitted signal.

[0071] The two aforementioned modified embodiments are equivalent to... Figure 4 The upper cylinder assembly 231 and the lower cylinder assembly 232 are integrally formed to create a single component, while retaining some features of a multi-piece structure. Specifically, in this modified embodiment, the upper cylinder space and the lower cylinder space in the single cylinder body respectively correspond to... Figure 4 The upper cylinder assembly 231 and the lower cylinder assembly 232 are provided with an upper cylinder space 2310 and a lower cylinder space 2320, respectively; in another modified embodiment, the upper cylinder portion and the lower cylinder portion in a single cylinder body respectively correspond to Figure 4 The upper cylinder assembly 231 and the lower cylinder assembly 232 are described in the embodiment. Therefore, multiple embodiments can achieve equivalent or similar technical functions to meet different product or production needs.

[0072] Furthermore, to enhance the stability between the metal cylinder 23 and the male end base 21, at least one side of the metal cylinder 23 may be provided with a connecting portion for connecting to the male end base 21, thereby ensuring a tight connection between the metal cylinder 23 and the male end base 21. Specifically, taking a through hole structure as an example, in this embodiment, please refer to... Figures 8A to 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.

[0073] Also, please refer to [the relevant document / reference]. Figures 8A to 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:

[0074] (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

[0075] The size and shape of the first through hole 233 or the second through hole 234 may be the same or different.

[0076] (2) The metal cylinder 23 can have a first through hole 233 on only one side.

[0077] (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.

[0078] "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 "not relative" means that the first through hole 233

[0079] The extended projection area of ​​the second through hole 234 does not overlap with the second through hole 234, or the two are located on non-opposite sides.

[0080] (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; Figure 9 For example, located in Figure 9The right side of the metal cylinder 23 on the left side is provided with a first through hole 233, located in Figure 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 Figure 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... Figure 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 Figure 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.

[0081] (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 Figure 3 and Figure 10 As shown, the two rows of metal grounding cylinders are arranged along the longitudinal axis (Y-axis).

[0082] 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.

[0083] 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... Figures 11A to 11C As shown, a first protrusion 233' is provided on one side (e.g., the front side) of the metal cylinder 23. The first protrusion 233' is formed by cutting or stamping a local area of ​​the metal cylinder 23 into a sheet, and then tilting the sheet outward so that it partially extends beyond the front side of the metal cylinder 23. A second protrusion 234' is provided on the other side (e.g., the rear side), and its formation structure can be the same as the first protrusion 233'. In this way, the structure of the first protrusion 233' and the second protrusion 234' can stably connect the metal cylinder 23 to the male end base 21. In addition, in some embodiments, the male end 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 an embedded method to provide a grounding path and electromagnetic shielding effect, without being limited to the use of insulating materials and injection molding processes.

[0084] Furthermore, in order to ensure that the connecting terminal 22 can be stably assembled into the metal cylinder 23 and held in the intended position, in this embodiment, please refer to [further details omitted]. Figures 2 to 4 As shown, at least one connecting terminal 22 can be fixed to a terminal block 24, and the terminal block 24 does not cover the fixing part 221 of the connecting terminal 22, so that the fixing status between the connecting terminal 22 and the transmission line L can be easily connected or inspected in subsequent procedures (but not limited thereto). Then, the terminal block 24, together with the connecting terminal 22 thereon, can be assembled into the metal cylinder 23. Specifically, the terminal block 24 has an upper mounting groove 241 and a lower mounting groove 242. The upper mounting groove 241 extends downward from the top surface of the terminal block 24 and forms an opening on one side of the terminal block 24 (e.g., the front / rear / left / right side). Figure 4 As shown, viewed from the front, the upper mounting groove 241 is recessed inward from the front side of the terminal block 24; the lower mounting groove 242 extends upward from the bottom surface of the terminal block 24 and forms an opening on one side of the terminal block 24 (e.g., front / rear / left / right side). Figure 4 As shown, from a frontal view, the lower mounting groove 242 is recessed inward from the front side of the terminal block 24.

[0085] Please refer to the above. Figures 2 to 4 , Figure 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 first cylinder mounting portion 236 and the second cylinder mounting portion 237 are provided on the lower cylinder assembly 232 for description. The first cylinder mounting portion 236 is used to be mounted to the upper seat mounting groove 241, and the second cylinder mounting portion 237 is used to be mounted to the lower seat mounting groove 242. Specifically, the first cylinder mounting portion 236 is a spring piece, which is formed by shearing or stamping a local area of ​​the lower cylinder assembly 232 and extends into the lower cylinder space 2320. The second cylinder mounting portion 237 is a protrusion, which is formed by stamping a local area of ​​the lower cylinder assembly 232 inward. When the terminal block 24 is installed into the metal cylinder 23 from top to bottom, the free end of the spring piece (first cylinder mounting part 236) will first extend into the lower mounting groove 242, and then be deformed and compressed due to the obstruction of the partition wall 243 between the upper mounting groove 241 and the lower mounting groove 242. After passing through the partition wall 243, it will embed into the upper mounting groove 241 and abut against the groove wall of the upper mounting groove 241 adjacent to the partition wall 243 (e.g., Figure 12 As shown), the protrusion (the second cylinder mounting portion 237) extends into the lower seat mounting groove 242 and abuts against the groove wall of the lower seat mounting groove 242 adjacent to the partition wall 243 (as shown). Figure 12 (As shown). However, depending on the actual needs of the product, the specific forms of the first cylinder mounting portion 236 and the second cylinder mounting portion 237 are not limited to the aforementioned structure. Furthermore, the horizontal width of the upper mounting groove 241 can be different from the horizontal width of the lower mounting groove 242. In this embodiment, the horizontal width of the upper mounting groove 241 can be smaller than the horizontal width of the lower mounting groove 242, and the horizontal width of the first cylinder mounting portion 236 can also be smaller than the horizontal width of the second cylinder mounting portion 237. Thus, when the terminal block 24 is assembled to the lower cylinder assembly 232 in the wrong direction, it will not be able to connect smoothly, achieving a foolproof effect.

[0086] To ensure the metal cylinder 23 has good grounding performance and electromagnetic interference immunity, please refer to [further details]. Figures 2 to 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...) Figure 4 and Figure 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...). Figure 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.

[0087] In the second implementation, please refer to Figure 13A and Figure 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...). Figure 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.

[0088] In the third implementation, please refer to Figure 14A and Figure 14B 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...). Figure 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.

[0089] In the fourth implementation, please refer to Figure 15A and Figure 15B As shown, the upper cylinder assembly 231 has a contact portion 2313 on one side (e.g., the front side). However, in other embodiments of this application, the upper cylinder assembly 231 can have multiple contact portions 2313 located on different sides. 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). Figure 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.

[0090] In the fifth implementation form, please refer to Figure 16A and Figure 16B 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 an arc-shaped configuration and connection relationship as in the fourth embodiment (the outer surface is directly connected to...). Figure 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.
