Technical Field

[0001] Cross - reference to Related Applications

[0001] This application claims priority to Chinese Patent Application No. 202320562828.0, filed on March 13, 2023, entitled "5G HIGH SPEED CONNECTOR". The content of this application is hereby incorporated by reference in its entirety into this specification.

[0002]

[0002] This patent application generally relates to electrical connectors, and more particularly to electrical connectors that can provide high signal integrity in harsh environments. The electrical connector may be a 5G high - speed connector.

Background Art

[0003]

[0003] Electrical connectors are used in many electronic systems. Generally, it is easier and more cost - effective to manufacture a system as separate electronic assemblies that can be joined together with electrical connectors. Electrical connectors may be used to interconnect electronic assemblies so that the electronic assemblies can cooperate as part of a system. For example, the connectors may be mounted on printed circuit boards inside two assemblies that are connected by mating the connectors. In other systems, it may not be practical to join two printed circuit boards by directly mating the connectors on those printed circuit boards. For example, when a system is assembled, the printed circuit boards may be too far apart for a direct connection between the connectors mounted on the printed circuit boards.

[0004]

[0004] In some systems, connections between electronic assemblies may be made by cables. The cables may be terminated with connectors that mate with connectors mounted on a printed circuit board. In this way, connections between electronic assemblies may be made by plugging connectors that are part of a cable assembly into connectors mounted on a printed circuit board. In other system architectures, the connector terminating one cable may mate with another connector terminating another cable.

[0005]

[0005] An example of a system in which assemblies are connected by cables is a modern automobile. For example, an automobile includes electronic control units (ECUs) for controlling various vehicle systems such as the engine, transmission (TCU), security system, emissions control system, lighting, advanced driver assistance systems (ADAS), entertainment system, navigation system, and cameras. These electronic control units may be manufactured as separate assemblies. To simplify the manufacture of automobiles, assemblies may be formed separately and then connected via cables that terminate at connectors that allow connection to mating board connectors that terminate other cables or are mounted on printed circuit boards within the assemblies.

[0006]

[0006] Automobiles present a harsh environment for electrical connectors. Automobiles can vibrate, which can cause connectors to disengage and become completely non-functional. Even if the vibration does not completely disrupt the operation of the connector, it can generate electrical noise, which can interfere with the operation of electronic equipment joined through the interconnect, including the connector. For example, noise can be generated as a result of the relative movement of components within the connector, which can alter the electrical properties of the connector. Variations in electrical properties, in turn, cause variations in the signals passing through the interconnect, which is a form of noise that interferes with the processing of the underlying signals.

[0007]

[0007] In automotive environments, electrical noise can also originate from automotive components that generate electromagnetic radiation. This radiation can couple to the conductive structures of connectors, potentially introducing noise into signals passing through those conductive structures. In automobiles, electromagnetic radiation can be generated by any of a number of components, such as spark plugs, alternators, or power switches. This noise can particularly disrupt high-speed signals, such as those used to transmit data over automotive networks. [Overview of the project] [Means for solving the problem]

[0039]

[0053] Next, an exemplary embodiment of an electrical connector according to the present disclosure will be described in detail with reference to the accompanying drawings. The electrical connector according to the present disclosure may be a connector having a single port and is configured to mate with a board connector (not shown) having a single port.

[0040]

[0054] Referring to FIGS. 1 and 2, FIG. 1 shows a perspective view of an electrical connector 1 according to some embodiments, and FIG. 2 shows a partially exploded view of the electrical connector 1 of FIG. 1.

[0041]

[0055] In the illustrated exemplary embodiment, the electrical connector 1 may include an insulating housing 100 and a terminal subassembly 200 inserted into the insulating housing 100 and fixed therein in a removable manner.

[0042]

[0056] In some embodiments, the insulating housing 100 may include a hollow cylinder. The insulating housing 100 may extend longitudinally (for example, in the y-direction shown in the figure) and may have a mounting end 101 and a mating end 102. As shown, the insulating housing 100 may have an opening formed in the mounting end 101 and an opening formed in the mating end 102.

[0043]

[0057] In some embodiments, the “mounting end” and “mating end” of the insulating housing 100 of the electrical connector 1 may refer to two opposite ends of the insulating housing 100 in the insertion direction (for example, the y-direction shown in the figure), respectively. Optionally, referring to the examples shown in Figures 1 and 2, the “mounting end” of the insulating housing 100 may refer to the end of the insulating housing 100 into which the terminal subassembly 200 is inserted, for example, the end indicated by reference numeral “101,” while the “mating end” of the insulating housing 100 may refer to the end of the insulating housing 100 opposite to the mounting end 101 in the insertion direction, for example, the end indicated by reference numeral “102.” The “mounting end” and “mating end” of other parts of the electrical connector may refer to them in substantially the same manner as those of the insulating housing 100.

[0044]

[0058] In some embodiments, the terminal subassemblies of the electrical connector are configured to be inserted into the insulating housing from the mounting end of the insulating housing and are fixedly disposed within the insulating housing in a removable manner. The mating end of the insulating housing may be configured to engage a mating component, such as a mating board connector (not shown).

[0045]

[0059] As shown in Figure 2, the terminal subassembly 200 of the electrical connector 1 may be inserted into the insulating housing 100 at the mounting end 101 of the insulating housing 100 in the longitudinal direction (e.g., the y-direction) of the insulating housing 100, or it may be disposed within a cavity surrounded by the hollow cylinder of the insulating housing 100. In some embodiments, the terminal subassembly 200 may be fitted into the insulating housing 100 in a removable manner. For example, the terminal subassembly 200 may be removed from the insulating housing 100 for repair or replacement.

[0046]

[0060] Referring to Figures 3-7, the terminal subassembly 200 of the electrical connector 1 may comprise a subassembly 205 and a first shield 210 and a second shield 220 fixedly disposed outside the subassembly 205. The first shield 210 and the second shield 220 may be mechanically and electrically coupled to each other.

[0047]

[0061] As shown in Figure 6, the first shield 210 of the terminal subassembly 200 may be provided adjacent to the mating end 102 of the insulating housing 100. The second shield 220 of the terminal subassembly 200 may be provided adjacent to the mounting end 101 of the insulating housing 100. The second shield 220 may be fixedly disposed and mounted on the outside of the subassembly 205. In some embodiments, the mounting portion of the first shield 210 may be fixedly disposed outside the mating portion of the second shield 220 and mechanically and electrically connected to the mating portion of the second shield 220. The mounting portion of the first shield 210 may be stacked with the mating portion of the second shield 220.

[0048]

[0062] In some embodiments, the subassembly 205 may include a cable 230, a terminal 260 connected to the cable 230, and an assembly housing 270 for housing the terminal 260. As shown in Figure 4, the terminal 260 may be inserted into the assembly housing 270. The assembly housing 270 may be inserted into the second shield 220 from the mounting end of the second shield 220 and partially inserted into the first cavity 212, so that at least a portion of the terminal 260 of the subassembly 205 extends beyond the mating end of the second shield 220 and is disposed within the mating portion of the first shield 210. The mating end of the terminal 260 is exposed through an opening 271 in the mating end of the assembly housing 270, an opening 216 in the mating end of the first shield 210, and an opening 131 in the mating end 102 of the insulating housing 100, so that it can engage with mating components (not shown).

[0049]

[0063] In some embodiments, the position limiting device may be provided on the terminal subassembly, and the stopping device may be provided in a cavity inside the insulating housing, and the stopping device engages with the position limiting device on the terminal subassembly inserted into the insulating housing, so that the terminal subassembly may be fixedly disposed within the insulating housing in a removable manner.

[0050]

[0064] In some embodiments, the opening 110 may be located on one side wall of the insulating housing 100, and the opening 110 may include a beam 120 extending from the mounting end 111 of the opening 110 toward the longitudinal fitting end 112 of the opening 110, as shown in Figure 3. The beam 120 comprises a distal end 121 and a first stop member 122 located on the distal end 121. The first stop member 122 may be a projection extending from the distal end 121 toward a cavity inside the insulating housing 100. As shown in Figure 4, when the terminal subassembly 200 is inserted into the insulating housing 100, the first stop member 122 engages with the second shield 220 of the terminal subassembly 200 and abuts against the outer surface of the second shield 220.

[0051]

[0065] Referring to Figure 4, the terminal subassembly 200 may be latched to the insulating housing 100 by a first stop member 122 of the beam 120. Optionally, the beam 120 may be configured as an elastically deformable member, and the first stop member 122 of the beam 120 may have a cam-shaped surface. When the terminal subassembly 200 is inserted into the insulating housing 100, the second shield 220 may engage with the first stop member 122, in which case the elastic force of the beam 120 itself pushes the beam 120, shifting it downward in Figure 4, thereby latching the second shield 220 in a direction perpendicular to the longitudinal direction of the insulating housing 100.

[0052]

[0066] In this way, the beam 120, acting as a stopping device located within the cavity of the insulating housing 100, exerts a biasing force on the second shield 220 of the terminal subassembly 200 toward the interior of the insulating housing 100 via the first stopping member 122 through its own elastic deformation, thereby exerting a biasing force on the second shield 220 in the short direction (the x-direction shown in the figure) perpendicular to the longitudinal direction. Under the influence of the biasing force in the short direction, relative movement of the terminal subassembly 200 in the short direction within the insulating housing 100 is prevented, resulting in a more stable structure for the electrical connector.

[0053]

[0067] In some embodiments, by using an elastically deformable beam 120 provided on the side wall of the insulating housing 100, the first stop member 122 is integrally formed with the insulating housing 100, simplifying the stop structure and reducing the time required to install the electrical connector. Such a configuration can reduce manufacturing costs. It should be understood that the structure of the first stop member 122 is not limited thereto. Optionally, an elastic member such as a spring may be provided between the side wall of the insulating housing 100 and the terminal subassembly 200 to exert an elastic effect on the terminal subassembly 200 so as to prevent the terminal subassembly 200 from moving in the short direction. Optionally, the electrical connector 1 may be further provided with various biasing members, as long as the biasing members penetrate the opening 110 of the insulating housing 100 and bias the terminal subassembly 200 toward the interior of the insulating housing 100.

[0054]

[0068] In some embodiments, the stopping device located within the cavity of the insulating housing 100 may include an engaging portion 103 located on the inner wall of the insulating housing 100. The engaging portion of the stopping device 103 may protrude toward the cavity inside the insulating housing 100, as shown in Figure 6. In the illustrated exemplary embodiment, the first shield 210 may include a first shield position limiting device 213 protruding outward from the outer surface of the first shield 210 in a direction away from the terminal subassembly 200 disposed within the first shield 210. When the terminal subassembly 200 is inserted longitudinally into the insulating housing 100, the engaging portion 103 on the insulating housing 100 abuts against the first shield position limiting device 213 located on the first shield 210, and the engaging portion 103 engages with the distal end of the first shield position limiting device 213.

[0055]

[0069] In some embodiments, the first shield 210 may include a hollow cylinder surrounded by a first sheet 211. The first shield position limiting device 213 may be formed as a projection 213a extending radially outward from the hollow cylinder in a direction perpendicular to the outer surface of the first sheet 211.

[0056]

[0070] Optionally, the proximal end surface of the engaging portion 103 provided on the inner wall of the insulating housing 100 contacts the distal end surface of the projection 213a formed on the first shield 210 in the longitudinal direction of the electrical connector 1.

[0057]

[0071] Optionally, the engaging portion 103 is provided circumferentially on the side wall adjacent to the side wall formed by the opening 110 and the beam 120 of the insulating housing 100.

[0058]

[0072] In this way, the engagement between the engaging portion 103 provided on the inner wall of the insulating housing 100 and the first shield position limiting device 213 of the first shield 210 provides a stopping function that reduces the risk of relative movement of the first shield 210 and the terminal subassembly 200 provided within the first shield 210 in the longitudinal and perpendicular directions (for example, the z-direction shown in the figure) relative to the insulating housing 100, thereby increasing the structural stability of the electrical connector 1.

[0059]

[0073] In some embodiments, the first shield may comprise a first sheet surrounding a first cavity for housing a mating interface and at least a portion of the second shield. The second shield may comprise a second sheet surrounding a second cavity for housing cables. A portion of the second shield is disposed within the first shield to form a lamination area.

[0060]

[0074] As shown in Figure 7, the first shield 210 may be formed from a first sheet 211, and the second shield 220 may be formed from a second sheet 221. The first sheet 211 and the second sheet 221 may be formed as hollow tubes. The tubes may surround the first cavity 212 and the second cavity 222. The perimeters of the first cavity 212 and the second cavity 222 may be defined by the first sheet 211 and the second sheet 221, respectively. The first cavity 212 may house a terminal 260 that is inserted into an assembly housing 270, and the assembly housing 270 houses the terminal 260. The assembly housing 270 may be partially inserted into the first cavity 212 of the first shield 210 through the second shield 220, as shown in Figure 4.

[0061]

[0075] Referring to Figure 8, in some embodiments, the terminal 260 may be formed as a longitudinally extending hollow cylindrical portion 261 at the mating end. The hollow cylindrical portion 261 of the terminal 260 may be configured to include a receiving portion 263 at its mating end. The hollow cylindrical portion 261 of the terminal 260 communicates longitudinally with the opening 271 at the mating end of the assembly housing 270 via the receiving portion 263. The receiving portion 263 may be configured as a flared shape that opens toward the opening 271 of the assembly housing 270. In some embodiments, the receiving portion 263 includes a tapered portion 265 that narrows longitudinally from the mating end of the hollow cylindrical portion 261 toward the proximal side of the hollow cylindrical portion 261. A portion of the hollow cylindrical portion 261 that forms a tapered portion 265 and has the smallest size in a cross-section perpendicular to the longitudinal direction (for example, the xy plane shown in Figure 8) forms a neck portion of the hollow cylindrical portion 261 near the fitting end of the hollow cylindrical portion 261. In a cross-section perpendicular to the longitudinal direction (for example, the xy plane shown in Figure 8), the size of the neck portion is smaller than the size of the body of the hollow cylindrical portion 261 near its proximal side (for example, the remaining portion of the hollow cylindrical portion 261 excluding the receiving portion 263 at the fitting end).

[0062]

[0076] Optionally, the receiving portion 263 includes a large-diameter opening 264 located at the mating end of the hollow cylindrical portion 261, a tapered portion 265 that narrows longitudinally from the large-diameter opening 264 toward the proximal side of the hollow cylindrical portion 261, and a small-diameter opening 266 adjacent to the tapered portion 265. In a cross-section perpendicular to the longitudinal direction of the electrical connector (for example, the xy plane shown in Figure 8), the small-diameter opening 266 has a size smaller than, for example, the size of the body of the hollow cylindrical portion 261 of the terminal 260 near its proximal side, thereby forming a neck portion of the hollow cylindrical portion 261 near the mating end of the hollow cylindrical portion 261. Optionally, the large-diameter opening 264 may be dimensioned to be, for example, greater than or equal to the size of the body of the hollow cylindrical portion 261 of the terminal 260 near its proximal side.

[0063]

[0077] In some embodiments, the receiving portion 263 may include a pair of terminals spaced apart from each other. The pair of terminals may be configured to mate with terminals of a mating connector, such as a board connector (not shown), which is inserted through an opening 271 in the assembly housing 270, and the terminals may be, for example, signal terminals. The large-diameter opening 264 of the receiving portion 263 is configured to receive the mating terminal to be connected, which is inserted through the opening 271 in the assembly housing 270. The tapered portion 265 is configured to guide the inserted mating terminal. The small-diameter opening 266 is configured to apply sufficient clamping force to the inserted mating terminal, enabling a reliable communication connection between the electrical connector 1 and the mating connector, such as a board connector, according to some embodiments.

[0064]

[0078] In some embodiments, the opening 271 at the mating end of the assembly housing 270 may be configured to have a guide portion 273. The guide portion 273 may communicate with an internal cavity of the assembly housing 270 for housing the terminal 260. The guide portion 273 may communicate with a receiving portion 263 at the mating end of the hollow cylindrical portion 261 of the terminal 260. In a cross-section perpendicular to the longitudinal direction of the electrical connector 1, at least a portion of the guide portion 273 may be shaped to have a size smaller than the size of the mating end of the hollow cylindrical portion 261.

[0065]

[0079] Referring further to Figure 8, in the illustrated exemplary embodiment, the guide portion 273 may include a first portion 274 that tapers longitudinally toward the proximal end of the mating end of the assembly housing 270 (for example toward the receiving portion 263 for the terminal 260), and a second portion 278 that extends linearly longitudinally toward the proximal end of the first portion 274. The second portion 278 communicates with the internal cavity of the assembly housing 270 for housing the terminal 260. The second portion 278 has a size smaller than the size of the mating end of the hollow cylindrical portion 261 in a cross-section perpendicular to the longitudinal direction of the electrical connector 1.

[0066]

[0080] Optionally, the first portion 274 of the guide portion 273 may be shaped like a funnel. The first portion 274 may have a large diameter portion 275 located at the fitting end of the assembly housing 270, a small diameter portion 276 adjacent to the second portion 278, and an inclined portion 277 tapering between the large diameter portion 275 and the small diameter portion 276. The second portion 278 may be shaped like a cylinder. As shown in Figure 8, in a cross-section perpendicular to the longitudinal direction (for example, the xy plane shown in the figure), the diameter of the small diameter opening 276 may be equal to the diameter of the second portion 278, and the diameter of the second portion 278 may be smaller than the diameter of the large diameter opening 264 of the receiving portion 263.

[0067]

[0081] In some embodiments, while inserting the mating terminal of the mating connector into the receiving portion 263 of the terminal 260, the mating terminal is guided into the receiving portion 263 under the guiding action of the guide portion 273 of the assembly housing 270 and electrically connected to the corresponding terminal. The opening 271 at the mating end of the assembly housing 270 of the electrical connector is composed of a guide portion 273, which consists of a first portion 274 having a tapered size and a second cylindrical portion 278 connected to the first portion 274 and having a reduced size. In the configuration of the second portion 278 having a diameter smaller than the diameter of the large-diameter opening 264 of the receiving portion 263, during the process of inserting the mating terminal of the mating connector into the receiving portion 263 of the terminal 260, the inserted mating terminal may first be guided by the first portion 274 of the guide portion 273 of the assembly housing 270 into the smaller second portion 278, and constrained by the reduced size of the second portion 278, the inserted mating terminal does not have to make direct frontal contact with the end face of the mating end of the receiving portion 263 (e.g., the large-diameter opening 264) after passing through the second portion 278. Thus, the mating end of the receiving portion 263 is not subjected to bending and deformation due to the longitudinal compressive pressure caused by the insertion of the mating terminal of the mating connector. Accordingly, the structural reliability and performance of the subassembly of the electrical connector according to this disclosure can be guaranteed and the service life of the electrical connector can be extended. In some embodiments, the tapered portion 265 and the small-diameter opening 266 of the receiving portion 263 can guide and clamp the inserted mating terminal without undesirable deformation of the mating end of the receiving portion 263. This can improve the overall stability of the mechanical and electrical connections of the electrical connector structure and extend the service life of the electrical connector.

[0068]

[0082] It should be recognized that the shape of the through-hole 271 of the assembly housing 270 shown in this disclosure is exemplary. Optionally, the guide portion 273 may be shaped like an hourglass (not shown). Optionally, a second portion of the guide portion having a reduced size may be provided longitudinally at a substantially intermediate position between the mating end of the assembly housing and the internal cavity for accommodating the terminal, the size of which the second portion is configured to be smaller than the size of the large-diameter opening of the receiving portion. To accommodate moderate rebound deformation of the inserted mating terminal, an expansion portion having an increasing size may be provided between the second portion and the internal cavity. The size of the expansion portion is provided to be smaller than the size of the mating end of the hollow cylindrical portion 261 in a cross-section perpendicular to the longitudinal direction of the electrical connector 1. Optionally, the inclination of the expansion portion may be configured to be less than that of the first portion, so as to ensure that the inserted mating terminal does not come into direct frontal contact with the end face of the mating end of the receiving portion (e.g., the large diameter opening 264) after passing through the second portion, thereby ensuring the mechanical and electrical connection between the electrical connector and the adapter connector of this disclosure.

[0069]

[0083] Referring to Figure 9, the metal sheet may have two edges joined together, the two edges connected to each other so that the tube encloses the cavity, and in the example shown, the two edges may have one or more interlocking parts, such as one or more interlocking protrusions and recesses. In the example shown in Figure 9, the second sheet 221 of the second shield 220 may have a protrusion 221a and a corresponding recess 221b. Once the second shield 220 is formed, the protrusion 221a is fitted into the recess 221b so that the protrusion 221a and recess 221b are interlocked, and further mechanical integrity can be provided to the second shield 220. The metal sheet can be punched, and by forming the metal sheet in this way, the manufacturing process can be simplified. It should be understood that the metal sheet may also be formed by other forming methods such as forging.

[0070]

[0084] As shown in Figure 6, the first shield position limiting device 213 is formed as a projection 213a extending radially outward in a direction perpendicular to the outer surface of the first sheet 211. The projection 213a extends away from the surface of the first sheet 211 and away from the first cavity 212, forming a latch mechanism. In this way, the first shield position limiting device 213 may be formed integrally with the first shield 210, thereby simplifying the structure of the electrical connector 1 and reducing manufacturing costs.

[0071]

[0085] Referring further to Figure 6, the engaging portion 103 of the insulating housing 100 extends from the inner wall of the insulating housing 100 toward the cavity inside the insulating housing 100. The engaging portion 103 is longitudinally aligned with the projection 213a, and when the terminal subassembly 200 is inserted into the insulating housing 100, the projection 213a of the terminal subassembly 200 engages with the engaging portion 103 of the insulating housing 100. This restricts the longitudinal and vertical movement of the terminal subassembly 200 within the insulating housing 100. It should be noted that the structure of the first shield position limiting device 213 is not limited to the form of the projection 213a, and a stop pin may be provided between the insulating housing 100 and the terminal subassembly 200 to reduce the risk of vertical movement of the terminal subassembly 200 within the insulating housing 100.

[0072]

[0086] In some embodiments, the electrical connector may further include a Contact Carrier Position Assurance (CCPA) which may be inserted into the insulating housing from the outside of the insulating housing in a direction perpendicular to the longitudinal direction of the insulating housing and positioned between the terminal subassembly and the insulating housing. In some embodiments, the Contact Carrier Position Assurance (CCPA) may include a stopping device. The stopping device of the Contact Carrier Position Assurance (CCPA) may extend into a cavity inside the insulating housing in a direction perpendicular to the longitudinal direction and engage with the mounting end of the first shield of the terminal subassembly inserted longitudinally into the insulating housing.

[0073]

[0087] Referring again to Figure 2, the electrical connector 1 may further include a Contact Carrier Position Assurance (CCPA) 300. The Contact Carrier Position Assurance (CCPA) 300 may be provided with a stop device 302, which may be configured to latch the terminal subassembly 200 within the insulating housing 100. When the terminal subassembly 200 is inserted into the desired position in the insulating housing 100, the Contact Carrier Position Assurance (CCPA) 300 may be pushed and inserted into the insulating housing 100, and the stop device 302 engages with the mounting end of the first shield 210 of the terminal subassembly 200, thereby reducing the risk of the terminal subassembly 200 coming out of the insulating housing 100. In this way, the stop device 302 prevents the terminal subassembly 200 from moving longitudinally within the insulating housing 100, thereby increasing the structural stability of the electrical connector 1.

[0074]

[0088] As shown in Figure 2, the Contact Carrier Position Assurance (CCPA) 300 has a base 301 extending in the longitudinal direction (y-direction) and a stop device 302 extending vertically from the end of the base 301 near the mounting end 101 of the insulating housing 100. In the operating state shown in Figure 6, the Contact Carrier Position Assurance (CCPA) 300 is fully inserted into the insulating housing 100, and the stop device 302 is engaged with the mounting end of the first shield 210, which is positioned on the second shield 220. Optionally, the stop device 302 engages with the end of the first shield 210 near the mounting end 101 of the insulating housing 100. In this way, the Contact Carrier Position Assurance (CCPA) 300 abuts against the side of the second shield 220, applying pressure to the second shield 220 and reducing the risk of longitudinal movement of the terminal subassembly 200.

[0075]

[0089] In some embodiments, the contact carrier position guarantee (CCPA) may further comprise two arms extending from the base, the two arms being provided near the mating end of the base, on two opposing sides of the base, respectively, in a longitudinal and transverse direction, and the two arms extending vertically in a direction perpendicular to the longitudinal and transverse directions.

[0076]

[0090] Optionally, windows may be configured on two opposing side walls of the insulating housing, perpendicular to the longitudinal direction and in the short direction. Optionally, one of the windows may be located on the same side wall as the beam and its opening of the insulating housing. The windows of the insulating housing may be configured such that, after the terminal subassembly is inserted into the insulating housing, a hook-type latch of the arm of the Contact Carrier Position Assurance (CCPA) is received and latched into the window.

[0077]

[0091] Referring further to Figure 2, the contact carrier position guarantee (CCPA) 300 may further comprise two arms 303. The two arms 303 are provided near the mating end of the base 301, on two opposing sides of the base 301, in a longitudinal and transverse direction. The two arms 303 extend perpendicularly from the two transverse ends of the base 301 in a longitudinal and transverse direction. The arms 303 are spaced apart from the stop device 302, which is provided at the mounting end of the base 301 and extends vertically as two arms 303.

[0078]

[0092] Optionally, the bottom wall of the insulating housing 100 may be provided with an opening into which the arm 303 is inserted. In the illustrated exemplary embodiment, a hook-type latch 304 is provided at the end of the arm 303 of the contact carrier position guarantee (CCPA) 300.

[0079]

[0093] As shown, the window 104 is configured on two opposing side walls of the insulating housing 100, and the window 104 may receive a hook-type latch 304. The hook-type latch 304 is received by the window 104 when the contact carrier position guarantee (CCPA) 300 is fully inserted into the insulating housing 100. In this case, the terminal subassembly 200 is locked into the insulating housing 100. By the hooking method described above, the contact carrier position guarantee (CCPA) 300 can be fixedly disposed within the insulating housing 100, thereby improving the stability of the latch operation and further enabling a more stable structure of the electrical connector 1. It should be understood that the structure of the insulating housing 100 for receiving the arm 303 is not limited thereto, and for example, alternatively, a recess may be provided in the inner wall of the insulating housing 100 for receiving the arm 303.

[0080]

[0094] Optionally, on each of the opposing sides, an additional window 104' may be provided on the side wall of the insulating housing 100, the additional window 104' located below the window 104, and when the contact carrier position guarantee (CCPA) 300 is partially inserted into the insulating housing 100, the hook-type latch 304 is received by the additional window 104'. In this state, the terminal subassembly 200 can move longitudinally within the insulating housing 100, thus allowing the position of the terminal subassembly 200 to be adjusted.

[0081]

[0095] Optionally, as shown in Figure 1, a longitudinally extending beam 120 that protrudes at the mating end may be formed on one of the two side walls of an insulating housing 100 formed with a window 104. A first stop member 122 extending into the cavity inside the insulating housing 100 may be provided at the distal end of the beam 120, and the first stop member 122 may abut against a second shield 220 of a terminal subassembly 200 inserted into the insulating housing 100.

[0082]

[0096] In some embodiments, the first shield may further comprise a stop device which may be formed on the inner surface of the first sheet, the stop device of the first shield may be disposed in the lamination area, the stop device of the first shield extending toward the first cavity in a direction perpendicular to the inner surface of the first sheet, and the second shield may further comprise a first slot configured to receive the stop device of the first shield, thereby mechanically connecting the first shield to the second shield.

[0083]

[0097] Referring to Figure 9, the first shield 210 further comprises a stop device 214 formed from a stop device 214a, which may be formed on the side wall of the first sheet 211. The stop device 214a may extend into the interior of the first cavity 212. The second shield 220 may further comprise a first slot 223 which may receive the stop device 214a. In this way, the first shield 210 is mechanically connected to the second shield 220. It should be noted that the method of connecting the first shield 210 to the second shield 220 is not limited thereto. Optionally, the first shield 210 may be screw-connected to the second shield 220, or alternatively, the first shield 210 may be further bond-connected to the second shield 220. The connection method of the present disclosure facilitates the sleeve-like configuration of the first shield 210 on the second shield 220, and the present disclosure enables a reduction in the overall size of the terminal subassembly 200 by providing a stop device 214a extending into the first cavity 212 on the side wall of the first sheet 211, thereby further reducing manufacturing costs.

[0084]

[0098] It should be noted that multiple stoppers may be provided on the first shield 210, and multiple corresponding slots may be provided on the second shield 220. For example, in an optional embodiment of the present disclosure, the first shield 210 may further comprise a second stopper device (not shown), which may be longitudinally provided in front of or behind the stopper device 214a, and the second shield 220 may further comprise a second slot (not shown) parallel to the first slot 223, the location of the second slot corresponding to the location of the second stopper device. It should be understood that the second stopper device and the second slot may be mated in the same way as the stopper device and the first slot. In this way, the stability of the mechanical connection of the first shield 210 to the second shield 220 is improved.

[0085]

[0099] In some embodiments, the second shield may have an elliptical cross-section in the stacking area, the elliptical cross-section comprising a first straight section and a second straight section, and a first curved section and a second curved section joined by the first straight section and the second straight section, and the second shield may have a convex section extending radially outward from the first curved section and the second curved section, respectively, in the stacking area and extending circumferentially.

[0086]

[0100] The second shield 220 shown in Figure 2 may have an elliptical cross section 225 in the stacking area, the elliptical cross section 225 may comprise a first straight section 225a, a second straight section 225b, a first curved section 225c, and a second curved section 225d joined to each other, the first slot 223 of the second shield 220 may be provided in the first straight section 225a of the second shield 220, and the second shield 220 may further comprise a protrusion 224 provided on the outer surface of the second shield 220, the protrusion 224 may project outward from the first curved section 225c and the second curved section 225d in a direction away from the second cavity 222 as shown in Figure 2, and the protrusion 224 may be formed as a raised portion extending around the second shield 220. The protrusion 224 may contact the first shield 210 so that the first shield 210 is electrically connected to the second shield 220. In this way, the frictional force between the first shield 210 and the second shield 220 is increased, and the structural stability of the terminal subassembly 200 is further improved.

[0087]

[0101] Optionally, as shown in Figure 7, the cable 230 of the electrical connector 1 may comprise a pair of insulated conductors 231a and 231b, surrounded by a cable shield and then covered by an insulating jacket. For termination, the insulating jacket may be removed to expose the cable shield. This operation of the cable 230 makes it possible to attach the insulated conductors 231a and 231b to the terminals of the board connector. The terminal 260 of subassembly 205 of terminal subassembly 200 may be crimped onto the insulated conductors 231a and 231b of the cable 230, so that the crimped ends of the terminal 260 are exposed, or the terminal 260 may be crimped onto the insulated conductors 231a and 231b of the cable 230 and then inserted into an assembly housing 270 that houses the terminal 260, as shown in Figure 4.

[0088]

[0102] The electrical connector 1 according to an exemplary embodiment may further include a collar 240. A portion of the cable shield is exposed by removing a portion of the cable jacket, and the exposed portion of the cable shield may be inserted into the collar 240, and the second shield 220 may be crimped around the collar 240 (as shown in Figures 4 and 7). In this way, a connection is formed between the cable shield and the second shield 220.

[0089]

[0103] Optionally, the terminal subassembly 200 may further comprise an impedance adapter 250 (as shown in Figures 4 and 7), which may be positioned around the cable 230. In some embodiments, the impedance adapter 250 may be a metal component and may be in electrical contact with the second shield 220. The impedance adapter 250 may be closer to the insulating conductor of the cable 230 than the second shield 220, and may substantially cover the portion of the insulating conductor of the cable 230 from which the cable shield has been removed. The impedance adapter 250 may be spaced away from the cable conductor to provide an impedance that matches the impedance of the conductor in the cable.

[0090]

[0104] The electrical connectors of this disclosure can be applied to fields such as 5G, new energy, and environmental protection. For example, the electrical connectors shown in Figures 1-15 of this disclosure may be 5G high-speed connectors.

Embodiments may also include any one of the above features or embodiments, or two or more combinations of the above features or embodiments.

[0092]

[0106] Those skilled in the art related to this embodiment should understand that various modifications of form and detail can be made without departing from the scope of the features described above.

[0093]

[0107] According to aspects of this application, several embodiments relate to an electrical connector. The electrical connector may include an insulating housing and a terminal subassembly disposed within the insulating housing. The terminal subassembly may include a first shield and a second shield fixedly and partially disposed within the first shield. The terminal subassembly may further include a position-limiting device thereon. A stop device configured to engage with the position-limiting device may be provided within the insulating housing. According to the technical solutions described in this application, during the manufacture of the electrical connector, the risk of relative movement of the terminal subassembly within the insulating housing can be reduced by the engagement between the stop device within the insulating housing and the position-limiting device on the terminal subassembly, so that the terminal subassembly is fixedly disposed within the insulating housing in a removable manner. Such a configuration can enable the electrical connector to improve structural stability and reduce the risk of loosening / disengaging from mating components due to vibration, thus providing beneficial effects such as a more consistent signal path.
