Description

Technical Field

[0001] The invention relates to a connector, belonging to the technical field of electrical connection devices. Background Art

[0002] Existing high-speed connectors typically include an outer housing, multiple terminal modules mounted on the housing, a fixing plate for securing each terminal module, and a grounding plate fixedly connected to the crimping ends of each terminal module. For example, the utility model patent with authorization publication number CN215645331U discloses a shielding component and a curved female connector using the shielding component. The curved female connector includes multiple parallel curved female wafers (i.e., terminal modules). Each curved female wafer includes two integrally mounted curved female insulators (i.e., plastic bodies) and two curved female shielding plates (i.e., shielding plates) located outside the insulators. Each curved female insulator is mounted with a curved female signal terminal. The terminal body and contact end of the curved female signal terminal are both wide-side coupled, while the crimping end is narrow-side coupled. The curved female shielding plate is equipped with an extended termination terminal at the crimping end of the curved female wafer. In one embodiment, the termination terminal is bent twice to align with the crimping end of the curved female signal terminal (i.e., signal fisheye) and is equipped with a fisheye structure (i.e., grounding fisheye). Both the grounding fisheye and the signal fisheye are used for crimping and securing to the printed circuit board. In addition, the bent female connector also includes a bent female conductive buckle plate (i.e., a ground plate) installed on the crimping end of the bent female chip and used to cooperate with two bent female shielding plates to fully shield the differential signal pairs at the crimping end of the bent female chip.

[0003] Among them, since the signal terminal is fixed on the plastic body through injection molding, the signal fisheye has reliable supporting strength, and the shielding sheet is generally fixed on the plastic body through hot rivets and is located on the outermost side of the terminal module. At the same time, the grounding fisheye has a long section in an overhanging state. When it is pressed onto the printed circuit board, the grounding fisheye is easily bent under the force, affecting the assembly quality of the product and even causing the connector to be scrapped.

DETAILED DESCRIPTION

[0018] In response to the technical problems existing in the prior art, the basic concept of the present invention is to provide a fisheye support platform at the end of the plastic body to prevent the grounding fisheye from deforming inward, and at the same time provide an outer blocking surface on the ground plate to prevent the grounding fisheye from deforming outward, thereby preventing the grounding fisheye from being bent under force when being pressed onto the printed circuit board.

[0019] The features and performance of the present invention are further described in detail below with reference to the embodiments.

[0020] Example 1 of the connector of the present invention: like Figure 1 As shown, the connector includes an outer shell 1, multiple terminal modules 2 mounted on the outer shell 1, a fixing plate 3 for fixing each terminal module 2, and a grounding plate 4 fixedly connected to the crimping end of each terminal module 2. The outer shell 1 includes a mating surface and a mounting surface. The mating surface can be plugged into other connectors, and the mounting surface is used to fix and place the terminal modules 2.

[0021] Terminal module 2 is the main part for transmitting differential signals. Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, the terminal module 2 has a plug-in end A and a crimping end B. The plug-in end A is used to plug into other connectors, and the crimping end B is used to crimp and fix to the printed circuit board. The terminal module 2 specifically includes a plastic body 21, terminals 22 fixed to the plastic body 21 by injection molding, and a shielding sheet 23 fixed to the side of the plastic body 22. The terminals 22 are arranged in pairs to form a signal differential pair. The terminals 22 are provided with a signal fisheye 221 at the crimping end of the terminal module 2, and a plug-in spring claw 222 at the plug-in end of the terminal module 2. The plug-in spring claws 222 of the two terminals 22 in a signal differential pair are arranged in front and back. The two terminals 22 are connected to the signal fisheye 221 through a torsion portion 223 at the crimping end. The spatial torsion of the torsion portion 223 causes the signal fisheyes 221 of the two terminals 22 to be arranged left and right.

[0022] Shielding sheets 23 are fixed on the two opposite sides of the plastic body 21. The two shielding sheets 23 are provided with grounding fisheyes 231 at the crimping end of the terminal module 2. The grounding fisheyes 231 and the above-mentioned signal fisheyes 221 are used for crimping and fixing with the printed circuit board. A pair of grounding fisheyes 231 are respectively provided on the left and right sides of a pair of signal fisheyes 221 (such as Figure 3 As shown, a pair of grounded fisheyes 231 are arranged front to back) to shield the signal fisheye 221, and combined with Figure 7 and Figure 8 As shown, the plastic body 21 is provided with a fisheye support 211 at the crimping end of the terminal module 2, which is used to mate with the inner side surface of the base of the grounding fisheye 231 to prevent the grounding fisheye 231 from deforming inward. In a terminal module 2, the fisheye support 211 is located exactly between the pair of grounding fisheyes 231 of the two shielding plates 23, thereby simultaneously preventing the pair of grounding fisheyes 231 from deforming inward. For a terminal module 2, its plastic body can be composed of two fixed halves, each of which is injection-molded with a row of terminals 22. The opposing end faces of the two plastic halves are bonded together, and a shielding plate 23 is fixed to each opposing end face. Of course, the plastic body of a terminal module 2 can also be integrally injection-molded.

[0023] At the same time, the plane where the grounding fisheye 231 is located is not the same plane as the plane where the main part of the shielding sheet 23 is located. The root of the grounding fisheye 231 and the main part of the shielding sheet 23 are connected by a bent portion 232 bent inwardly ( Figure 3 and Figure 8 As shown in FIG, the main portion of the shielding sheet 23 is parallel to the grounding fisheyes 231, and the bent portions 232 connected to the pair of grounding fisheyes 231 are symmetrically arranged. Because the fisheye support 211 extends beyond the bent portions 232, the fisheye support 211 is provided with a stepped surface 212 that mates with the inner side of the bent portion 232 to ensure that the bent portion 232 and the base of the grounding fisheyes 231 are in contact with the fisheye support 211.

[0024] Combine Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 as well as Figure 13 As shown, the ground plate 4 has an inner end D and an outer end C, wherein the outer end C is used to face the printed circuit board, and the inner end D extends toward one side of the terminal module. The height h of the ground plate 4 is sufficient to at least cover the torsional portion 223 of the terminal 22 to achieve better shielding effect and optimize the crosstalk performance of the connector.

[0025] Specifically, the ground plate 4 is provided with multiple longitudinally extending vertical walls 43. The crimping end of the terminal module 2 is inserted between two adjacent vertical walls 43. The ground plate 4 is provided with multiple signal cavities 46 for pairs of signal fisheyes 221 to pass through, allowing the signal fisheyes 221 to pass through the ground plate 4 and crimp onto the printed circuit board. A certain electrical spacing exists between the signal fisheyes 221 and the walls of the signal cavity 46. Multiple signal cavity partitions 45 are provided between the two longitudinal walls 43. Each signal cavity 46 is provided with a signal cavity partition 45 on both longitudinal sides to separate different pairs of signal fisheyes 221 in the same terminal module 2, thereby achieving signal shielding. Furthermore, the height of the signal cavity partitions 45 is substantially consistent with that of the ground plate 4. The aforementioned torsional portion 223 is located between two adjacent longitudinal walls 43 and the signal cavity partitions 45 on both longitudinal sides of the signal cavity 46 to ensure effective shielding.

[0026] The middle signal cavity partitions 45 are arranged in pairs, and fisheye support blocks 41 are respectively provided on the longitudinal wall 43 at positions corresponding to the space between the pair of signal cavity partitions 45 and at positions corresponding to the outer spaces of the signal cavity partitions 45 at both ends. The fisheye support blocks 41 provided on two adjacent longitudinal walls 43 are arranged symmetrically. The fisheye support blocks 41 include a stop step 411 and an outer stop surface 412 connected to the stop step 411. Figure 8 As shown, the stopper step 411 can engage with the outer side surface of the bent portion 232 on the shielding plate 23, thereby limiting the assembly limit of the terminal module 2 and the grounding plate 4 and preventing the grounding eye 231 from deforming outward. At the same time, the outer stopper surface 412 can fit with the outer side surface of the base of the grounding eye 231 to prevent the grounding eye 231 from deforming outward.

[0027] The bent portion 232 on the shielding plate 23 extends at an angle and is not perpendicular to the grounding fisheye 231 and the main body of the shielding plate. Therefore, the step surface 212 and the stopping step 411 on the fisheye support platform 211 are both inclined surfaces. In this way, when the terminal module 2 and the grounding plate 4 are assembled, the bent portion 232 abuts against the stopping step 411, and the stopping step 411 can apply an inward force to the bent portion 232 to make it close to the step surface 212.

[0028] In addition, if Figure 8、 Figure 10 and Figure 12 As shown, blocks 42 are connected between the signal cavity partitions 45 arranged in pairs and on the outer sides of the signal cavity partitions 45 at both ends. The end faces of the blocks 42 facing the fisheye support platform 211 are engaged with the fisheye support platform 211 to limit the assembly limit of the terminal module 2 and the grounding plate 4.

[0029] At the same time, through-holes 47 are formed between the two lateral sides of the stopper 42 and the corresponding fisheye support block 41. The through-holes 47 allow the grounding fisheye 231 to pass through, thereby achieving a press-fit connection with the printed circuit board. Furthermore, the two lateral sides of the stopper 42 (i.e., the sides located within the through-holes 47) can fit against the inner side surface of the base of the grounding fisheye 231, forming an inner blocking surface 421. This, together with the fisheye support platform 211, can limit the inward deformation of the grounding fisheye 231 and ensure that the blocking surface areas on the inner and outer sides of the base of the grounding fisheye 231 are equal. Figure 8 As shown, the end face of the block 42 facing away from the fisheye support platform 211 is flush with the end face of the grounding plate 4, and one end of the inner blocking surface 421 and the outer blocking surface 412 are aligned. In this way, when crimped to the printed circuit board, the blocking effect on the inward and outward deformation of the grounding fisheye 231 is consistent, which plays a better role in preventing the grounding fisheye 231 from bending under force.

[0030] In addition, among the signal cavity partitions 45 located on both longitudinal sides of the signal cavity 46, a signal cavity connecting block 44 is connected between one of the signal cavity partitions 45 and the longitudinal wall 43 on one side, and a signal cavity connecting block 44 is also connected between the other signal cavity partition 45 and the longitudinal wall 43 on the other side. The two signal cavity connecting blocks 44 are located on both sides of the signal cavity 46, which strengthens the strength of the signal cavity and can avoid lateral warping of the grounding plate 4.

[0031] In summary, the connector of the present invention, by providing the fisheye support platform 211 and the fisheye support block 41, supports the grounding fisheye 231, preventing it from bending during the crimping process. Furthermore, the signal cavity connecting blocks 44, located on either side of the signal cavity 46 and connected to the longitudinal walls 43 of the ground plate, strengthen the signal cavity and prevent lateral warping of the ground plate components. Furthermore, the inner surface of the ground plate 4 extends toward the terminal module, and the height of the ground plate 4 at least covers the torsion area of ​​the fisheye, thereby optimizing the connector's crosstalk performance.

[0032] Figure 14 The figure shows the crosstalk between adjacent terminals in a terminal module. Figure 15 Shown is a diagram of crosstalk between adjacent terminals in another terminal module. Figure 16 The figure shows the crosstalk between the terminals facing each other on adjacent terminal modules. Figure 17The figure shows the crosstalk performance between diagonally opposite terminals of adjacent terminal modules. The red line in the figure shows the data when the ground plate does not cover the fisheye torsion area, and the blue line shows the data when the ground plate covers the fisheye torsion area. As can be seen from the figure, when the ground plate covers the fisheye torsion area, the crosstalk performance is optimized, whether it is between adjacent terminals within a terminal module, between terminals directly opposite adjacent terminal modules, or between terminals diagonally opposite adjacent terminal modules.

[0033] in addition Figure 18 The figure shows the insertion loss of each terminal in a certain adjacent terminal module. The red line in the figure shows the data when the ground plate does not cover the fisheye torsion area, and the blue line shows the data when the ground plate covers the fisheye torsion area. As can be seen from the figure, whether the ground plate covers the torsion area has little effect on the insertion loss.

[0034] In other embodiments of the connector, the signal cavity connecting block may be provided on only one side of the signal cavity, and the signal cavity connecting block is connected to the longitudinal wall of the ground plate. Of course, in other embodiments, the signal cavity connecting block may not be provided.

[0035] In other embodiments of the connector, a stopper may no longer be provided on the grounding plate. In this case, the fisheye support platform alone is used to limit the inward deformation of the grounding fisheye. In this case, the structure through which the pair of grounding fisheyes pass is a larger through cavity, like the signal cavity.

[0036] In other embodiments of the connector: the bent portion on the shielding plate can be perpendicular to the main portion of the shielding plate and the grounding fisheye. At this time, the step surface on the fisheye support platform and the stopping step are not inclined surfaces, the step surface on the fisheye support platform is perpendicular to the end face of the fisheye support platform, and the stopping step is perpendicular to the outer blocking surface.

[0037] In other embodiments of the connector, the shielding sheet may be fixed to only one side of the plastic body.

[0038] In other embodiments of the connector: the bending portion may no longer be provided on the shielding sheet, and the main portion of the grounding fisheye and the shielding sheet are coplanar, and there is no need to provide a step surface on the fisheye support platform, and there is no need to provide a stop step on the grounding plate. The installation limit of the terminal module can be achieved by other structures, such as by a stop block that cooperates with the end face of the fisheye support platform, or by providing a stop structure at other positions of the grounding plate that cooperates with the stop at other positions of the plastic body.

[0039] In other embodiments of the connector, the fisheye support block may not be provided on the grounding plate. In this case, the side surface of the longitudinal wall may be used to form an outer blocking surface to limit the outward deformation of the grounding fisheye.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The scope of patent protection of the present invention shall be based on the claims. Any equivalent structural changes made using the description and drawings of the present invention shall be included in the scope of protection of the present invention.
