Description

Technical Field

[0001] The present application relates to the field of connectors, and in particular to a shielding cage assembly and an electrical connector thereof. Background Art

[0002] For related prior art, please refer to China Utility Model Patent Announcement CN207611910U, which discloses a hot-swappable interface connector (see its attached document for details). Figure 2 ), an elastic contact boss 131 is formed on its bottom wall 13, and the elastic contact boss 131 is integrally connected to the bottom wall 13 through the cantilever 133 along the plug-in and unplugging direction of the docking connector. In some usage scenarios, a heat dissipation module (similar to the radiator 4 in the prior art) needs to be integrated and installed on the outer surface of the elastic contact boss 131. Due to the structural characteristics of the elastic contact boss 131 and the cantilever 133, the heat dissipation module will not be in close contact with the outer surface of the elastic contact boss 131 after being installed on the outer surface of the elastic contact boss 131. The reason is that the heat dissipation module has design tolerances, assembly tolerances and other factors. In fact, when the heat dissipation module is installed on the elastic contact boss 131, it will be slightly biased forward or slightly biased backward, which will cause the heat dissipation module to be in loose contact with the outer surface of the elastic contact boss 131, thereby affecting the heat dissipation performance.

[0003] In addition, in the existing technical solution, the cantilever 133 has a certain length (along the plug-in and unplugging direction of the docking connector), and the extension direction of the two process gaps on both sides of the cantilever 133 is a straight line in the same direction as the plug-in and unplugging direction of the docking connector. During the process of stamping the cantilever 133, the pulling force on the cantilever 133 is relatively concentrated, and the cantilever 133 is prone to cracking, thereby causing defects, especially at the root of the cantilever 133.

[0004] In addition, the matching structure of the cantilever 133 and the elastic contact boss 131 in the prior art solution has a greater obstruction to the insertion of the docking connector and requires a greater insertion force, which also needs to be improved.

[0005] Therefore, it is necessary to improve the existing technical solutions to overcome the above-mentioned defects in the existing technology. Utility Model Content

[0039] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0040] For the accuracy of the description of the entire application, please refer to Figure 1 For reference, specifically, the direction of the X-axis is defined as the left-right direction; the direction of the Y-axis is defined as the up-down direction, where the positive direction of the Y-axis is upward; and the direction of the Z-axis is defined as the front-back direction, where the positive direction of the Z-axis is backward.

[0041] Please refer to Figures 1 to 6 As shown, a shielding cage assembly disclosed in the present application includes a cage body 1 provided with a top plate 11. The cage body 1 is formed by enclosing a metal plate and defines a docking cavity 10. The docking cavity 10 defines an insertion port 101 at one end thereof. The docking cavity 10 is configured to accommodate a docking module (e.g., a docking connector) inserted through the insertion port 101. A boss portion 12 is formed on the top plate 11. The boss portion 12 includes a boss contact portion 121 that at least partially protrudes into the docking cavity 10 and a resilient wall 122 that integrally connects the boss contact portion 121 to the top plate 11. The boss contact portion 121 contacts a docking module (not shown, e.g., a docking connector) inserted into the docking cavity 10.

[0042] Please refer to Figures 1 to 6As shown, a preferred embodiment is that along the plug-in and unplug-out direction (front-back direction) of the docking module, the two ends of the boss portion 12 are integrally connected to the top plate 11 through the elastic walls 122. In a preferred embodiment, two elastic walls 122 are connected to either end of the boss portion 12 along the plug-in and unplug-out direction of the docking module, and the two elastic walls 122 located at the same end of the boss portion 12 are spaced apart along the width direction. Among them, in a preferred embodiment of the present application, the boss portion 12 is connected to the top plate 11 only through the elastic wall 122, and the boss portion 12 is formed by integrally drawing / stretching the top plate 11. A floating gap 1201 is formed around the boss portion 12 and the top plate 11.

[0043] The elastic wall 122 can undergo elastic deformation, and the boss portion 12 can be displaced along the plug-in and unplug-in direction of the docking module, and can also be displaced along the thickness direction of the top plate 11. A preferred embodiment is as follows: the elastic wall 122 is a metal sheet extending along the plug-in and unplug-in direction of the docking module and bent along the thickness direction of the top plate 11. A specific embodiment can be selected as follows: the cross-section of the elastic wall 122 along the plane passing through the plug-in and unplug-in direction of the docking module and the thickness direction of the top plate 11 is in a horizontal S-shape, or V-shape, or a horizontal C-shape, or U-shape, or a zigzag shape, or a wavy shape, etc., so that the elastic wall 122 can be telescopically deformed along the plug-in and unplug-in direction of the docking module, and can also be elastically deformed along the thickness direction of the top plate 11, thereby achieving the effect of displacement of the boss portion 12 along the plug-in and unplug-in direction of the docking module and along the thickness direction of the top plate 11.

[0044] In the present application, the boss portion 12 can be used to install a heat dissipation module, such as a heat dissipation fin assembly, etc. The structural matching design of the elastic wall 122 and the boss contact portion 121 can make the boss contact portion 121 more compatible with the heat dissipation module assembled thereon. When the structure of the heat dissipation module and the boss contact portion 121 is slightly biased forward or slightly biased backward, the elastic wall 122 can be deformed to achieve fine adjustment of the position of the boss contact portion 121 to match and compensate. This can make the heat dissipation module and the boss contact portion 121 fit more closely. In addition, when the docking module (docking connector) is inserted into the docking cavity 10 from the insertion port 101 along the front-to-back direction, the elastic wall 122 can be deformed, which is also beneficial to the contact tightness between the boss contact portion 121 and the docking module.

[0045] Please refer to Figures 2 to 6As shown, along the thickness direction (up and down direction) of the top plate 11 as the viewing direction, a processing seam 1220 is formed on each side of the elastic wall 122, and the extension path of the processing seam 1220 along the plug-in and unplugging direction of the docking module is non-linear, such as the arc shape shown in the drawings of the embodiment of the present application. The extension path of the elastic wall 122 along the plug-in and unplugging direction of the docking module is non-linear. Such a design can avoid the problem of concentrated pulling force on the elastic wall 122 during the stamping process of the elastic wall 122, and can effectively avoid the risk of cracking in local positions of the elastic wall 122. In addition, through the structure of the elastic wall 122 in the present application cooperating with the boss contact portion 121, the insertion obstruction of the boss portion 12 to the docking module (docking connector) can be effectively reduced, and the insertion force of the docking module can be effectively reduced; in addition, due to the characteristics of the elastic wall 122 that can stretch and deform along the plug-in and unplug direction of the docking module, and can elastically deform along the thickness direction of the top plate 11, the insertion force of the docking module changes more evenly during the process of inserting the docking module into the docking cavity 10, making the insertion feel smoother, and there will be no sense of frustration caused by transient changes in the insertion force.

[0046] In the embodiment of the present application, the processing process of forming the boss portion 12 is roughly as follows: the first step: a whole piece of metal plate is subjected to integrated drawing / stretching processing (that is, the metal plate of the positive piece is squeezed and stretched downward so that a local position of the metal plate is recessed downward) to form the boss contact portion 121; the second step: through a stamping process, a floating gap 1201 and a processing seam 1220 are stamped around the boss contact portion 121, and at this time the elastic wall 122 is flat; the third step, through drawing / stretching processing (that is, the elastic wall 122 is partially squeezed and stretched downward so that a local position of the elastic wall 122 is recessed downward or protrudes upward), the elastic wall 122 is formed into a shape curved along the thickness direction of the top plate 11.

[0047] Please refer to Figures 4 to 6 As shown, the elastic wall 122 protrudes into the docking cavity 10 along the thickness direction of the top plate 11 to form a lowest point D1, and the boss contact portion 121 protrudes into the docking cavity 10 along the thickness direction of the top plate 11 to form a lowest point D2. A preferred embodiment is that the lowest point D2 is lower than the lowest point D1. When the docking module is inserted into the docking cavity 10 from the insertion port 101, it first contacts the elastic wall 122 and then contacts the boss contact portion 121, which can make the insertion feel smoother. When the docking module is fully inserted into the docking cavity 10, the upper surface of the docking module only contacts the inner surface of the boss contact portion 121, ensuring that the docking module is in close contact with the boss contact portion 121 after being fully inserted.

[0048] It should be noted that the description that the lowest point D2 is lower than the lowest point D1 includes the case where the boss portion 12 is located below the cage body 1; specifically, when the boss portion 12 is located below the cage body 1, the boss contact portion 121 protrudes into the docking cavity 10, Figure 1 The viewing angle is actually that the boss contact portion 121 protrudes upward. In this case, the lowest point D2 is lower than the lowest point D1. Figure 1 The viewing angle should be understood as that the lowest point D2 is located above the lowest point D1.

[0049] The shielding cage assembly of the present application is generally used to cooperate with one or more connector modules (not shown) to form a complete electrical connector, which can be installed in equipment such as base stations. Specifically, the connector module includes an insulating body (not shown) and a plurality of conductive terminals (not shown) fixed within the insulating body. Each conductive terminal includes a terminal fixing section fixed within the insulating body, a terminal contact section that at least partially protrudes into the docking cavity 10 for electrically docking with the docking module, and a terminal docking section that protrudes outside the insulating body and cage body 1 for electrically contacting the docking circuit board.
