Description

Technical Field

[0001] This invention relates to an electrical connector, and more particularly to a cable electrical connector. Background Technology

[0002] With the development of technology, various connectors for different electronic products have emerged, among which cable connectors are one of the most widely used and popular electrical connectors. Currently, the TYPE-C connector for cables is widely used as a reversible connector. However, the shield structure of the current TYPE-C connector is relatively close to the high-speed transmission terminal, which can easily affect the high-frequency characteristics of the TYPE-C connector. Furthermore, when the TYPE-C connector is pressed down after mating with another connector, the shield is prone to compression and deformation, resulting in collapse. Summary of the Invention

[0003] This invention provides a cable connector with excellent high-frequency characteristics.

[0004] The cable connector of the present invention includes an insulating body, a plurality of terminals, and a shield. The plurality of terminals are disposed on the insulating body and include a plurality of high-speed signal transmission terminals. Each terminal has a mating end for connection with another connector along a mating axis. The shield is partially stacked on the insulating body. The shield includes a sheet-like body, a cutout portion, two first sheet-like bends, and a second sheet-like bend. The first sheet-like bend, the sheet-like body, the other first sheet-like bend, and the second sheet-like bend are sequentially circumferentially connected to form the cutout portion. The cutout portion covers the mating ends of these terminals. The first sheet-like bends correspond to these high-speed signal transmission terminals along the mating axis. The mating end of each high-speed signal transmission terminal is at a distance of distance I relative to the edge of the first sheet-like bend and the cutout portion. The second sheet-like bend corresponds to the remaining terminals along the mating axis. Each mating end of the remaining terminals is at a distance II relative to the edge of the second sheet-like bend and the cutout portion. Distance I is greater than distance II.

[0005] Preferably, each of the first sheet-like bends described above has a first elastic portion and a first connecting portion. The first elastic portion is connected to the first connecting portion along the mating axis. The first connecting portion is connected between the second sheet-like bend and the sheet-like body.

[0006] Preferably, the second sheet-like bend described above has a second elastic portion and a second connecting portion. The second elastic portion is connected to the second connecting portion along the mating axis. The second connecting portion is connected between the two first connecting portions of the two first sheet-like bends.

[0007] Preferably, the second spring portion described above has a necked-out profile near the second connecting portion.

[0008] Preferably, the second sheet-like bend described above also has two protrusions. The two protrusions extend from the second connecting portion away from the hollow portion and gradually move away from the second spring piece portion.

[0009] Preferably, each of the first connecting portions of the first sheet-like bend has a notch facing the hollow portion.

[0010] Preferably, in the docking axis, the edge of the sheet-like body and the hollowed-out portion is at a distance of three relative to the edge of the first sheet-like bend and the hollowed-out portion, and the edge of the sheet-like body and the hollowed-out portion is at a distance of four relative to the edge of the second sheet-like bend and the hollowed-out portion. Distance three is greater than distance four.

[0011] Preferably, the aforementioned hollowed-out portion is divided into region one and region two. Region one is adjacent to the first sheet-like bend and the sheet-like body along the docking axis. Region two is adjacent to the second sheet-like bend and the sheet-like body along the docking axis. The dimension of region one along the docking axis is larger than the dimension of region two along the docking axis.

[0012] Preferably, the device further includes a housing with a positioning groove and a receiving space. The shielding sheet has a positioning portion vertically connected to the sheet-like body. The positioning portion fits into the positioning groove of the housing. The receiving space of the housing accommodates the insulating body, the terminals, and the shielding sheet.

[0013] Preferably, the aforementioned sheet-like body is located on a plane. The distance between the mating end of each high-speed signal transmission terminal projected onto the plane and the edge of the first sheet-like bend and hollow portion projected onto the plane is greater than the distance between the mating end of each of the other terminals projected onto the plane and the edge of the second sheet-like bend and hollow portion projected onto the plane.

[0014] Based on the above, in the cable connector of the present invention, the distance between the shield and the high-speed signal transmission terminal can be adjusted by the structural design of the shield, so that the high-speed signal transmission terminal is farther away from the shield than the other terminals, thus avoiding the high-frequency characteristics of the cable connector being affected by the high-speed signal transmission terminal being too close to the shield. Accordingly, compared with the structural relationship between the shield and the high-speed signal transmission terminal in conventional cable connectors, the shield of the cable connector of the present invention is farther away from the high-speed signal transmission terminal, thus exhibiting good high-frequency characteristics.

[0055] Figure 1 This is a schematic diagram of a cable electrical connector according to an embodiment of the present invention. Rectangular coordinates XYZ are provided here for subsequent description and reference of the components. Please refer to... Figure 1 The cable connector 100 in this embodiment is, for example, a TYPE-C connector for cables, and is adapted to be connected to another electrical connector (not shown) along the mating axis (i.e., along the X-axis).

[0056] Figure 2 yes Figure 1 A partial exploded view of the cable connector. Please refer to... Figure 1 and Figure 2 In this embodiment, the cable connector 100 includes an insulating body 110, a plurality of terminals 120, a shielding plate 130, and a housing 140. The terminals 120 are disposed along the Z-axis on the insulating body 110, and the shielding plate 130 is partially stacked on the insulating body 110 along the Z-axis. The housing 140 includes an inner shell 142 and an outer shell 144. The insulating body 110, the plurality of terminals 120, and the shielding plate 130 are disposed along the Z-axis on the inner shell 142, and the accommodating space 144-1 of the outer shell 144 accommodates the insulating body 110, the plurality of terminals 120, the shielding plate 130, and the inner shell 142.

[0057] In detail, in this embodiment, the insulating body 110 includes a first component 111 and a second component 112. During the manufacturing process of the cable connector 100, the first component 111 is bonded to the terminals 120, and the second component 112 is sandwiched between the terminals 120 and the shielding sheet 130. In this embodiment, the bonding between the first component 111 and the terminals 120 is achieved, for example, by insert molding technology, but is not limited thereto. In other embodiments, the first component 111 and the second component 112 may be an integrally formed structure.

[0058] Figure 3 yes Figure 1 A partially enlarged top view of a component of a cable connector. Figure 4 yes Figure 1 The image shows a top view of the shielding plate of the cable connector 100. It should be noted that this view is provided to clearly illustrate the structural relationships of the cable connector 100. Figure 3 Only the inner shell 142 of the multiple terminals 120, shielding plate 130, and housing 140 is shown. Please refer to... Figure 3 In this embodiment, the terminals 120 include a plurality of high-speed signal transmission terminals 122, namely SuperSpeed ​​differential signal #1 (TX1+, TX1-, RX1+, and RX1-) and SuperSpeed ​​differential signal #2 (TX2+, TX2-, RX2+, and RX2-). These high-speed signal transmission terminals 122 have mating ends T1, and the remaining terminals 124 (non-high-speed signal transmission terminals) have mating ends T2. The mating ends T1 of these high-speed signal transmission terminals 122 and the mating ends T2 of the remaining terminals 124 are adapted to be connected to another electrical connector (not shown) along the mating axis (i.e., along the X-axis).

[0059] It should be noted that these high-speed signal transmission terminals 122 and the remaining terminals 124 are arranged along the arrangement axis (i.e., along the Y-axis), and the mating ends T1 of these high-speed signal transmission terminals 122 and the mating ends T2 of the remaining terminals 124 are flush along the arrangement axis (i.e., the Y-axis). Furthermore, Figure 3 The grounding terminal that is shielded by the other components also belongs to the other terminals 124.

[0060] Please refer to Figure 4In this embodiment, the shielding sheet 130 includes a sheet-like body 131, a hollow portion 132, two first sheet-like bends 133, and one second sheet-like bend 134. The two first sheet-like bends 133 and the one second sheet-like bend 134 are arranged along the arrangement axis (i.e., along the Y-axis), and one of the first sheet-like bends 133, the sheet-like body 131, the other first sheet-like bend 133, and the second sheet-like bend 134 are sequentially connected to form the hollow portion 132. Here, the sheet-like body 131, the two first sheet-like bends 133, and the one second sheet-like bend 134 are, for example, an integrally formed structure, but are not limited thereto.

[0061] For details, please refer to Figure 3 In this embodiment, the cutout portion 132 covers the mating ends T1 and T2 of these terminals 120 along the Z-axis. The first sheet-like bends 133 correspond to these high-speed signal transmission terminals 122 along the mating axis (i.e., along the X-axis), and the second sheet-like bends 134 correspond to the remaining terminals 120 along the mating axis (i.e., along the X-axis). The mating end T1 of each high-speed signal transmission terminal 122 is at a distance D1 relative to the edge E1 of the first sheet-like bend 133 and the cutout portion 132, and the mating end T2 of each of the remaining terminals 124 is at a distance D2 relative to the edge E2 of the second sheet-like bend 134 and the cutout portion 132, and the distance D1 is greater than the distance D2.

[0062] In other words, in this embodiment, the sheet-like body 131 is located in the XY plane, and the hollow portion 132 projected onto the XY plane covers the mating ends T1, T2 of these terminals 120 projected onto the XY plane. Thus, the distance D1 between the mating end T1 of each high-speed signal transmission terminal 122 projected onto the XY plane and the edge E1 of the first sheet-like bend 133 projected onto the XY plane and the hollow portion 132 is greater than the distance D2 between the mating end T2 of each of the remaining terminals 124 projected onto the XY plane and the edge E2 of the second sheet-like bend 134 projected onto the XY plane and the hollow portion 132.

[0063] For more details, please also refer to Figure 3 and Figure 4In this embodiment, the cutout portion 132 is divided into region one 132-1 and region two 132-2. Region one 132-1 is adjacent to the first sheet-like bend 133 and the sheet-like body 131 along the docking axis (i.e., along the X-axis), and region two 132-2 is adjacent to the second sheet-like bend 134 and the sheet-like body 131 along the docking axis (i.e., along the X-axis). Region one 132-1 and region two 132-2 respectively cover the docking ends T1 of these high-speed signal transmission terminals 122 and the docking ends T2 of the remaining terminals 124 along the Z-axis, and the dimension of region one 132-1 along the docking axis (i.e., along the X-axis) is larger than the dimension of region two 132-2 along the docking axis (i.e., along the X-axis).

[0064] In other words, such as Figure 4 As shown, in the docking axis (i.e., the X-axis), the edge E3 of the sheet-like body 131 and the hollowed-out portion 132 is at a distance of 3D3 relative to the edge E1 of the first sheet-like bend 133 and the hollowed-out portion 132, and the edge E3 of the sheet-like body 131 and the hollowed-out portion 132 is at a distance of 4D4 relative to the edge E2 of the second sheet-like bend 134 and the hollowed-out portion 132, and the distance 3D3 is greater than the distance 4D4.

[0065] Therefore, in this embodiment, the cable connector 100 can adjust the distance between the shield 130 and the high-speed signal transmission terminal 122 through the structural design of the shield 130, avoiding the high-speed signal transmission terminal 122 from being too close to the shield 130 and affecting the high-frequency characteristics of the cable connector 100. Accordingly, compared with the structural relationship between the shield and the high-speed signal transmission terminal in conventional cable connectors, the shield 130 of the cable connector 100 in this embodiment is farther away from the high-speed signal transmission terminal 122, thus having good high-frequency characteristics.

[0066] In addition, please refer to Figure 2 and Figure 3 In this embodiment, the shielding sheet 130 also has two positioning portions 135 perpendicularly connected to the sheet-like body 131 along the Z-axis, and the inner shell 142 of the housing 140 also has two positioning grooves 142-1 corresponding to the two positioning portions 135 respectively. Each positioning portion 135 is fitted into the corresponding positioning groove 142-1 to restrict the movement of the shielding sheet 130 in the docking axis (i.e., the X-axis) and the alignment axis (i.e., along the Y-axis).

[0067] The following provides further details about shielding plate 130.

[0068] Please refer to Figure 4In this embodiment, each first sheet-like bend 133 has a first elastic portion 133-1 and a first connecting portion 133-2, and the first elastic portion 133-1 is connected to the first connecting portion 133-2 relative to the hollow portion 132 along the mating axis (i.e., the X-axis). The second sheet-like bend 134 has a second elastic portion 134-1 and a second connecting portion 134-2, and the second elastic portion 134-1 is connected to the second connecting portion 134-2 relative to the hollow portion 132 along the mating axis (i.e., the X-axis). The second connecting portion 134-2 of the second sheet-like bend 134 is connected between the two first connecting portions 133-2 of the two first sheet-like bends 133, and the first connecting portion 133-2 of one first sheet-like bend 133, the sheet-like body 131, the first connecting portion 133-2 of the other first sheet-like bend 133, and the second connecting portion 134-2 of the second sheet-like bend 134 are sequentially connected in a loop to form the hollow portion 132.

[0069] In detail, in this embodiment, the sheet-like body 131 has two recesses 131-1 facing the hollowed-out portion 132 and respectively adjacent to the two first connecting portions 133-2, and each first connecting portion 133-2 of the first sheet-like bend 133 has a notch 133-3 facing the hollowed-out portion 132. The second elastic portion 134-1 of the second sheet-like bend 134 has a necked-out profile 134-3 near the second connecting portion 134-2, and the second sheet-like bend 134 also has two protrusions 134-4 extending from the second connecting portion 134-2 away from the hollowed-out portion 132 and gradually moving away from the second elastic portion 134-1.

[0070] As described above, the sheet-like body 131 and the two first sheet-like bends 133 are designed with recesses 131-1 and notches 133-3, which weakens the structure of the two first sheet-like bends 133 and gives them better elasticity. Furthermore, the second elastic portion 134-1 and the second connecting portion 134-2 of the second sheet-like bend 134 are designed with a necked-out profile 134-3 and two protrusions 134-4, respectively, which weakens the structure of the second elastic portion 134-1 of the second sheet-like bend 134 and allows the stress of the second connecting portion 134-2 to be distributed among the two protrusions 134-4, giving the two first sheet-like bends 133 better elasticity and making them less prone to deformation. This prevents the two first sheet-like bends 133 and one second sheet-like bend 134 from being compressed and deformed, causing collapse, when the cable connector 100 is connected to another connector (not shown). This improves the reliability of the cable connector 100 and increases its service life.

[0071] In summary, in the cable connector of the present invention, the distance between the shield and the high-speed signal transmission terminal can be adjusted by the structural design of the shield, making the high-speed signal transmission terminal farther away from the shield relative to the other terminals. This avoids the high-speed signal transmission terminal being too close to the shield, which would affect the high-frequency characteristics of the cable connector. Accordingly, compared to the structural relationship between the shield and the high-speed signal transmission terminal in conventional cable connectors, the shield of the cable connector of the present invention is farther away from the high-speed signal transmission terminal, thus exhibiting excellent high-frequency characteristics. Furthermore, the shield also increases the connection structure dimension of the sheet-like bend relative to the sheet-like body, which is equivalent to increasing the lever arm of the sheet-like bend. When the cable connector is mated with another connector, the increased lever arm prevents the sheet-like bend from collapsing.
