Description

Technical Field

[0001] This application relates to a male connector, and more particularly to a male connector that is divided from top to bottom into a fixed part, a multi-segmented intermediate section, and an abutment part, wherein the projection range formed by the multi-segmented structure of the intermediate section can correspond to the fixed part. Background Technology

[0002] A connector is a general term for all connecting components and accessories used in the transmission of electronic signals and power. Its main function is to establish and maintain connections between circuits. It is responsible not only for transmitting power but also for transmitting data. It is an important component in any modern electronic system. From mobile phones and computers to large industrial machinery, everything relies on connectors to complete its basic functions.

[0003] As applications and installation locations change, connectors also come in various structural types to adapt to and meet usage requirements. These include, for example, good shielding performance to reduce electromagnetic interference, emphasis on mating stability, durability, waterproofing, dustproofing, or vibration resistance. Therefore, as an indispensable component of modern electronic systems, the design and application of connectors continuously evolve with technological innovation and changing market demands. Thus, developing connectors with excellent structures to gain market favor is a key issue addressed in this application. Utility Model Content

[0004] In order to stand out in the highly competitive market, the creator, with years of professional experience in the design, processing and manufacturing of various power or signal connectors, and adhering to the spirit of continuous improvement, has finally developed a male connector assembly with a multi-segment structure and projection offset configuration, as well as its male connector and connection terminal, after long-term research and experimentation. It is hoped that the advent of this application will gain market favor.

[0005] The purpose of this application is to provide a connection terminal with a multi-segment structure and projection offset configuration. The connection terminal is divided from top to bottom into a fixing part, an intermediate section, and an abutting part. The fixing part is used to fix to a transmission line, the abutting part is used to abut against a conductive contact on a circuit board, and the intermediate section connects the fixing part and the abutting part respectively. The intermediate section has multiple bends to form a multi-segment structure. The multi-segment structure includes multiple extension segments, and the two extension segments that are horizontally furthest apart form a projection range between each other. The fixing part can be completely within the projection range, and the fixing part will be close to one of the two furthest extension segments, forming a wire fixing space between the fixing part and the other extension segment of the two furthest extension segments. The wire fixing space is used to accommodate the transmission line. Thus, since the fixing part and the wire fixing space are within the projection range, the space occupied by the connecting terminal can be effectively utilized. At the same time, the downward pressure transmitted by the fixing part can be gradually transmitted to the abutting part through the various extensions of the multi-segment structure, so that the pressure is gradually dispersed in the middle section, effectively avoiding stress concentration in a single area, thereby improving the durability and stability of the structure.

[0013] Optionally, the abutting portion can be completely within the projection range.

[0014] Another objective of this application is to provide a male connector with a multi-segment structure and projection offset configuration, comprising a male base and at least one connecting terminal as described in the foregoing objective. The connecting terminal is directly or indirectly fixed to the male base.

[0015] Optionally, the male end base includes a first base body and a second base body, the first base body being located below the second base body, and the cross-sectional area of ​​the first base body being smaller than the cross-sectional area of ​​the second base body.

[0016] Optionally, the male connector further includes at least one metal cylinder, each of which can be fixed to the male base, and the metal cylinder has a cylinder space for accommodating at least one connecting terminal.

[0017] Optionally, the metal cylinder includes an upper cylinder assembly and a lower cylinder assembly. The upper cylinder assembly has an upper cylinder space. The lower cylinder assembly is connected to the upper cylinder assembly in an up-down configuration along the vertical axis and is located below the upper cylinder assembly. The lower cylinder assembly has a lower cylinder space, which communicates with the upper cylinder space to form a cylinder space together.

[0018] Another object of this application is to provide a male connector assembly with a multi-segment structure and projection offset configuration, the male connector assembly including a transmission line and a male connector as described above. The fixing portion of the connection terminal is electrically connected to the transmission line.

[0019] Optionally, the transmission line includes a core wire, a first insulating layer, a metal braided mesh layer, and a second insulating layer.

[0036] This application discloses a male connector assembly with a multi-segment structure and projection offset configuration, as well as its male connector and connecting terminals. The design is applied in connector group C and is suitable for signal or power transmission in electronic devices. The basic architecture of connector group C is first introduced here; please refer to [link to relevant documentation]. FIGS. 1A-1BAs 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.

[0037] As above, in one embodiment, please refer again to FIGS. 1A-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 connects to multiple transmission lines L, please refer to [reference needed]. FIG. 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.

[0038] 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. FIG. 1B The upper left corner is used as the left side direction of the component. FIG. 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... FIG. 1B The lower left corner serves as the front direction of the component. FIG. 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. FIG. 1B The area above is considered the top (top) side of the component. FIG. 1B The area below is used as the bottom (bottom) side direction of the component.

[0039] Please refer to the above. FIGS. 1A-4As 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 representation of 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.

[0040] 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]. FIGS. 1A-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.

[0041] Additionally, please refer to FIGS. 1A-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... FIG. 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.

[0042] Please refer to the above. FIGS. 1A-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.

[0043] Furthermore, please refer to [the relevant documents / references]. FIGS. 1A-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.

[0044] First, please refer to FIG. 2 , FIG. 5 and FIG. 6 As shown, the first structural form is a "multi-segment structure with projection offset configuration". 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. This multi-segment structure 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. Preferably, the vertical segment 226 is completely parallel to the vertical axis. However, in actual production, due to tolerances or design limitations, as long as the deviation angle θ between the vertical segment 226 and its own vertical axis does not exceed 10 degrees, it falls under the category of the vertical segment 226 referred to in this application.

[0045] Please refer to the above. FIG. 2 and FIG. 5As 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 z1 in a straight line, but this is not a limitation. In a modified embodiment of this application, please refer to... FIG. 7 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.

[0046] Please refer to the following: FIG. 2 , FIG. 5 and FIG. 6 As 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. Specifically, the projection range V refers to the range formed between the parts of the two vertical segments 226 that are furthest apart horizontally. Furthermore, the fixing part 221 will be completely within the projection range V (including the edge of the projection range V) and will be close to one of the two furthest vertical segments 226, for example, FIG. 6 The leftmost vertical segment 226, such that the fixing part 221 is connected to another vertical segment 226 (e.g., FIG. 6 A wire fixing space 220 is formed between the rightmost vertical segment 226, and this wire fixing space 220 is used to accommodate the core wire L1. In other words, the fixing part 221 and the transmission line L (core wire L1) are both fixed in the wire fixing space 220. Thus, since the fixing part 221 is located within the projection range V and will be offset closer to one of the vertical segments 226, and the transmission line L (core wire L1) is located in the wire fixing space 220, the following effects can be achieved:

[0047] (1) The downward pressure transmitted by the fixing part 221 can be gradually transmitted to the abutment part 223 through each extension section of the multi-segment structure, so that the pressure is 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 located within the projection range V, so that the pressure direction of the connecting terminal 22 remains consistent, but it is not limited thereto; and

[0048] (2) Since the fixing part 221 has an offset design, the wire fixing space 220 can be in the projection range V, so the space occupied by the connecting terminal 22 can be effectively utilized; in addition, when the connecting terminal 22 is located in the metal cylinder 23, it can also ensure that the transmission line L (core wire L1) will not be too close to the metal cylinder 23, and maintain good electrical performance.

[0049] In addition, please refer to FIG. 2 and FIGS. 5-6 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.

[0050] Secondly, please refer to FIG. 2 and FIG. 5 As shown, the second 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 z1 to pass through part of their structure (e.g., FIG. 5As shown, the fixing part 221 and the abutment part 223 are arranged along the same vertical axis z1 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 direction of the vertical axis z1, 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 aligned supports, the deformation occurs uniformly in the direction of the vertical axis z1, ensuring that the force direction of the connecting terminal 22 is consistent. This allows the abutment part 223 to smoothly abut against the conductive contact P1, while effectively preventing local stress concentration in the local bending area of ​​the connecting terminal 22, which could lead to breakage or damage.

[0051] Please refer to the above. FIG. 2 and FIG. 5 As shown, in some embodiments, the arrangement of the wire fixing space 220 and the abutment portion 223 in three-dimensional space can be passed through by the same vertical axis z2, so that the wire fixing space 220 and the abutment portion 223 are arranged along the vertical axis z2 to form an axially corresponding arrangement. Please refer to FIG. 8 As shown, when the transmission line L (core wire L1) is located in the wire fixing space 220 and fixed to the fixing part 221, the transmission line L (core wire L1) can also form an axially corresponding arrangement. In other words, the transmission line L and the connecting terminal 22 will form a support relationship that overlaps in axial height and has a consistent and vertical downward and rebound path, which helps to maintain stable and uniform contact pressure. At the same time, it can reduce local buckling or torsion when under force. For application environments that require repeated insertion and removal and spring pressure, it can effectively reduce the risk of fatigue or breakage of the connecting terminal 22. Therefore, the aforementioned coaxial double support structure design, that is, the fixing part 221 and the wire fixing space 220 can respectively form an axially corresponding arrangement with the abutment part 223 along their respective vertical axes z1 and z2, can further reduce the risk of twisting, stress concentration and fatigue of the connecting terminal 22 caused by lateral force. It is worth mentioning that, depending on the actual needs of the product, the connection terminal 22 can have both a "multi-segment structure and projection offset configuration" and a "coaxial spatial configuration", or it can only have a "multi-segment structure and projection configuration".

[0052] Additionally, please refer to FIGS. 1A-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.

[0053] Please refer to the above. FIGS. 1A-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. 9As 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).

[0054] Additionally, please refer to FIGS. 1A-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.

[0055] Furthermore, please refer to FIG. 10As 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 do not overlap, but 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.

[0056] 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.

[0057] 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]. FIGS. 2-4As 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). FIG. 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). FIG. 4 As shown, from a frontal view, the lower mounting groove 242 is recessed inward from the front side of the terminal block 24.

[0058] Please refer to the above. FIGS. 2-4 , FIG. 11 As 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., FIG. 11 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). FIG. 11(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.
