Description

Technical Field

[0001] The invention relates to the technical field of Fakra data connector manufacturing, in particular to a Fakra connector shielding structure. Background Art

[0002] Fakra connectors are coaxial signal transmission connectors. Initially, they were mainly used for the transmission of radio frequency signals. After the emergence of coaxial and LVDS signal converters in the market, their application range has been expanded to the field of video signal transmission. They are widely used in the fields of vehicle navigation, vehicle electronic instruments, 360 panoramic systems, vehicle automatic driving systems, etc. They are important components for signal transmission between vehicle multimedia devices. Fakra connectors have the advantages of good signal stability, fast transmission rate, high cost performance, and small size.

[0003] In actual application, the Fakra connector is installed in the mechanism housing. However, in the prior art, high-quality video circuit signals are transmitted at a sub-nanosecond pixel rate, and the Fakra connector itself lacks an effective shielding structure, and there is no effective means to ensure that its metal conductive seat is always in a stable contact state with respect to the mechanism housing. As a result, the signal is easily affected by the external magnetic field during transmission in the Fakra connector, and the anti-interference effect is poor. Therefore, it is urgent for technicians to solve the above problems. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a Fakra connector shielding structure with a simple structural design, which ensures that the Fakra connector is protected from external magnetic field interference during actual application and ensures stable and reliable signal transmission.

[0005] In order to solve the above technical problems, the present invention relates to a Fakra connector shielding structure, including a Fakra connector, a first mechanism shell and a second mechanism shell. The Fakra connector is placed horizontally along the left and right directions. The first mechanism shell is placed horizontally and arranged on the upper side of the Fakra connector. The second mechanism shell is placed vertically and arranged on the lower side of the Fakra connector. The above Fakra connector includes a metal conductive seat, an insulating plastic seat and a shielding sheet. The metal conductive seat is inserted into the insulating plastic seat along the right to left direction. The shielding sheet is formed by connecting a first elastic contact portion, a fixing portion and a second elastic contact portion in sequence. The fixing portion is clamped and fixed between the metal conductive seat and the insulating plastic seat. The first elastic contact portion is used to elastically press against the first mechanism shell, and it is continued to extend from the top wall of the fixing portion and is bent multiple times. The second elastic contact portion is used to elastically press against the second mechanism shell, and it is continued to extend from the bottom wall of the fixing portion and is bent multiple times.

[0006] As a preferred structural design form of the shielding sheet in the technical solution of the present invention, along the extension direction of the fixing portion, the first elastic contact portion is sequentially connected by the first vertical connecting section, the first right-leaning straight transition section, the second vertical connecting section and the first right-leaning elastic contact claw. The second elastic contact portion is sequentially connected by the third vertical connecting section, the second right-leaning straight transition section, the fourth vertical connecting section and the first left-leaning elastic contact claw.

[0007] As a further improvement of the technical solution of the present invention, the number of the first right-leaning elastic contact claws is set to be multiple and evenly distributed along the width direction of the second vertical connecting section. The number of the first left-leaning elastic contact claws is also set to be multiple and evenly distributed along the width direction of the fourth vertical connecting section.

[0008] As a further improvement of the technical solution of the present invention, opposite to the first mechanism housing, a first arc-shaped bent contact section is provided at the free end of the first right-leaning elastic contact claw. Opposite to the second mechanism housing, a second arc-shaped bent contact section is provided at the free end of the first left-leaning elastic contact claw.

[0009] As another preferred structural design form of the shielding sheet in the technical solution of the present invention, along the extension direction of the fixing portion, the first elastic contact portion is sequentially connected by a first arc-shaped bending transition section, a horizontal transverse section, and a second right-leaning elastic contact claw. The second elastic contact portion is sequentially connected by a second arc-shaped bending transition section, a right-leaning straight line connecting section, and a second left-leaning elastic contact claw.

[0010] As a further improvement of the technical solution of the present invention, the number of the second right-leaning elastic contact claws is set to be multiple and evenly distributed along the width direction of the horizontal transverse section. The number of the second left-leaning elastic contact claws is also set to be multiple and evenly distributed along the width direction of the right-leaning straight connecting section.

[0011] As a further improvement of the technical solution of the present invention, opposite to the first mechanism housing, a third arc-shaped bent contact segment is provided on the second right-leaning elastic contact claw. Opposite to the second mechanism housing, a fourth arc-shaped bent contact segment is provided on the second left-leaning elastic contact claw.

[0012] As a further refinement of the technical solution of the present invention, the above-mentioned metal conductive seat includes a metal conductive part, an insulating column and a wiring terminal. Among them, the metal conductive part includes a conductive shell body and a plug-in column. The plug-in column is formed by the left side wall of the conductive shell body continuing to extend to the left, and a first accommodating cavity is arranged therein. The wiring terminal is passed through and fixed in the insulating column, and is placed in the above-mentioned first accommodating cavity as a whole. The metal conductive seat is plugged and docked with the insulating plastic seat along the right to left direction by means of the above-mentioned plug-in column. Correspondingly, a second accommodating cavity is arranged in the insulating plastic seat for placing the above-mentioned plug-in column. The fixing part is sleeved on the plug-in column, and correspondingly, a through hole adapted to the shape of the plug-in column is opened thereon.

[0013] As a further improvement of the technical solution of the present invention, at least one limiting hole is provided on the fixing portion, and accordingly, a limiting column adapted to the limiting hole is extended rightward along the right side wall of the insulating plastic seat.

[0014] As a further improvement of the technical solution of the present invention, an avoidance notch is provided on the insulating plastic seat corresponding to the above-mentioned fixing portion.

[0015] As a further improvement of the technical solution of the present invention, a limiting convex strip is provided on the plug-in column. The limiting convex strip runs in the left-right direction, the number of which is set to at least one, and is evenly distributed circumferentially along the side wall of the plug-in column. Correspondingly, at least one limiting notch matching the above-mentioned limiting convex strip is provided around the circumferential side wall of the through hole.

[0016] Compared with the traditionally designed Fakra connector, in the technical solution disclosed in the present invention, an additional shielding sheet is provided, which is clamped and fixed between the metal conductive seat and the insulating plastic seat to ensure that the metal conductive seat and the outer shell of the peripheral mechanism remain in an electrically conductive state, so that the Fakra connector itself is always in a good shielding state during actual application, thereby effectively reducing the impact of external electromagnetic interference on the signal transmission process and ensuring the reliability and stability of signal transmission.

DETAILED DESCRIPTION

[0039] In the description of the present invention, it is necessary to understand that the terms "left", "right", "up", "down", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0040] The present invention will be further described in detail below with reference to specific embodiments. Figure 12 and 3 respectively show the structural schematic diagram of the first embodiment of the Fakra connector shielding structure in the present invention. It can be seen that it is mainly composed of a Fakra connector 1, a first mechanism housing 2 and a second mechanism housing 3. The Fakra connector 1 is placed horizontally along the left and right directions. The first mechanism housing 2 is placed horizontally and arranged on the upper side of the Fakra connector 1. The second mechanism housing 3 is placed vertically and arranged on the lower side of the Fakra connector 1. It should be noted here that the above-mentioned first mechanism housing 2 and the second mechanism housing 3 are the top plate and the side plate of the mechanism housing, respectively. Such naming is only to facilitate the following description and the illustration, so that those skilled in the art can fully understand the technical solution disclosed in the present invention.

[0041] Figure 3 , Figure 4 The exploded schematic diagram and assembly diagram of the Fakra connector in the first embodiment of the Fakra connector shielding structure of the present invention are respectively shown. It can be seen that it is mainly composed of a metal conductive seat 11, an insulating plastic seat 12 and a shielding sheet 13. The metal conductive seat 11 is inserted into the insulating plastic seat 12 from right to left. The shielding sheet 13 is composed of a first elastic contact portion 131, a fixing portion 132 and a second elastic contact portion 133 connected in sequence (as shown in FIG. Figure 8 The fixing portion 132 is clamped and fixed between the metal conductive seat 11 and the insulating plastic seat 12 (as shown in Figure 5 , 6 As shown in ). The first elastic contact portion 131 is extended from the top wall of the fixed portion 132 and is formed by multiple bends. It is sequentially connected by a first vertical connecting section 1311, a first right-leaning straight transition section 1312, a second vertical connecting section 1313 and a first right-leaning elastic contact claw 1314. Among them, the first right-leaning elastic contact claw 1314 is used to elastically press against the above-mentioned first mechanism housing 2. The second elastic contact portion 133 is extended from the bottom wall of the fixed portion 132 and is formed by multiple bends. It is sequentially connected by a third vertical connecting section 1331, a second right-leaning straight transition section 1332, a fourth vertical connecting section 1333 and a first left-leaning elastic contact claw 1334. Among them, the first left-leaning elastic contact claw 1334 is used to elastically press against the above-mentioned second mechanism housing 3 (as shown in ). Figure 8 , 9 In this way, it is ensured that the metal conductive seat 11 and the peripheral mechanism housing (i.e., the first mechanism housing 2 and the second mechanism housing 3) are kept in an electrically conductive state, so that the Fakra connector 1 is always in a good shielding state during the actual application process, thereby effectively reducing the impact of external electromagnetic interference on the signal transmission process, and ensuring the reliability and stability of signal transmission.

[0042] As a further optimization of the Fakra connector shielding structure, the number of the first right-leaning elastic contact claws 1314 is preferably set to be multiple, and they are evenly distributed along the width direction of the second vertical connecting section 1313; the number of the first left-leaning elastic contact claws 1334 is also preferably set to be multiple, and they are evenly distributed along the width direction of the fourth vertical connecting section 1333 (such as Figure 8 , 9 As shown in ). In this way, when the Fakra connector 1 is assembled in place relative to the mechanism housing, the first right-leaning elastic contact claw 1314 and the first left-leaning elastic contact claw 1334 thereof are elastically pressed against the first mechanism housing 2 and the second mechanism housing 3 respectively in a multi-point contact manner, thereby ensuring the reliability and stability of the first right-leaning elastic contact claw 1314 and the first left-leaning elastic contact claw 1334 contacting the first mechanism housing 2 and the second mechanism housing 3 respectively, that is, ensuring the reliability of electrical conduction between the shielding sheet 13 and the mechanism housing, thereby ensuring that the Fakra connector 1 has good shielding performance during actual application.

[0043] Furthermore, as a further improvement of the technical solution of the present invention, the structure of the shielding sheet 13 can be optimized as follows: opposite to the first mechanism housing 2, a first arc-shaped bent contact section 13141 is provided at the free end of the first right-leaning elastic contact claw 1314. Opposite to the second mechanism housing 3, a second arc-shaped bent contact section 13341 (such as Figure 8 , 9 ). In the process of installing the Fakra connector 1 into the mechanism housing, the presence of the first arc-shaped bent contact section 13141 can effectively prevent the first right-leaning elastic contact claw 1314 from being scratched during the displacement relative to the first mechanism housing 2; similarly, the presence of the second arc-shaped bent contact section 13341 can effectively prevent the first left-leaning elastic contact claw 1334 from being scratched during the displacement relative to the second mechanism housing 3.

[0044] Generally speaking, the Fakra connector 1 can adopt a variety of methods to achieve reliable clamping of the shielding sheet 13. However, a design structure with a simple structural design, convenient positioning and assembly of the shielding sheet 13, and high assembly efficiency is recommended here. Specifically, the metal conductive seat 11 is mainly composed of several parts such as a metal conductive member 111, an insulating column 112, and a terminal 113. Among them, the metal conductive member 111 includes a conductive shell body 1111 and a plug-in column 1112. The plug-in column 1112 is formed by the left side wall of the conductive shell body 1111 continuing to extend to the left, and a first accommodating cavity 11121 is provided therein. The terminal 113 is penetrated and fixed in the insulating column 112, and is integrally placed in the above-mentioned first accommodating cavity 11121. The metal conductive seat 11 is plugged and docked with the insulating plastic seat 12 along the right-to-left direction by means of the above-mentioned plug-in column 1112. Correspondingly, a second accommodating cavity 121 is provided in the insulating plastic seat 12 for placing the above-mentioned plug-in column 1112. The fixing portion 132 is sleeved on the plug-in post 1112, and correspondingly, a through hole 1321 (such as Figure 4-6 , as shown in 8-13).

[0045] It should be noted that, in order to reduce the difficulty of assembling the shielding sheet 13 relative to the plug-in post 1112 and the stability after assembly, the fitting tolerance between the two is preferably a clearance fit, and the maximum single-side clearance is controlled within 0.05 mm.

[0046] In addition, as a further optimization of the above technical solution, at least one limiting hole 1322 can be opened on the fixing portion 132, and accordingly, a limiting column 122 (such as Figure 4 , 5 , 7, 8, and 11). By adopting the above technical solution, the shielding sheet 13 can be effectively prevented from rotating circumferentially relative to the plug-in column 1112, ensuring that the first right-leaning elastic contact claw 1314 and the first left-leaning elastic contact claw 1334 thereon are reliably pressed against the first mechanism housing 2 and the second mechanism housing 3, respectively, thereby ensuring that the Fakra connector 1 has good shielding performance.

[0047] For the same purpose as above, a limiting convex strip 11122 may also be provided on the plug-in column 1112. The limiting convex strip 11122 extends in the left-right direction, and the number thereof is at least one, and is evenly distributed circumferentially along the side wall of the plug-in column 1112. Correspondingly, at least one limiting notch 13211 (such as 1321 ... Figure 4 , 5, 7, 8, 12, 13, and 14). By adopting the above technical solution, the shielding sheet 13 can also effectively prevent the shielding sheet 13 from rotating circumferentially relative to the plug-in column 1112 after installation.

[0048] Of course, for the same purpose as above, an escape notch 123 may be provided on the insulating plastic seat 12 corresponding to the fixing portion 132. The width of the escape notch 123 is consistent with that of the fixing portion 132 (eg Figure 2-6 , 10, and 11). By adopting the above technical solution, the shielding sheet 13 can also effectively prevent the shielding sheet 13 from rotating circumferentially relative to the plug-in column 1112 after installation. In addition, the presence of the avoidance notch 123 can also effectively reduce the axial length of the Fakra connector 1, making it have a more compact design structure.

[0049] However, it should be noted that the above three solutions all have good application effects on solving the problem of the shielding plate 13 rotating relative to the plug-in post 1112. Therefore, technical personnel in this field can select according to factors such as actual application scenarios and specific molding methods during the process of implementing the structural design of the Fakra connector 1. Of course, ignoring the manufacturing and cost, the above three solutions can also be tried on the same Fakra connector 1 at the same time to ensure that the Fakra connector 1 has a more stable shielding performance.

[0050] Fig.15 , Fig.16 The structural schematic diagram and the front view of the second embodiment of the Fakra connector shielding structure of the present invention are respectively shown; Fig.17 , Fig.18 The exploded schematic diagram and three-dimensional assembly of the Fakra connector in the second embodiment of the Fakra connector shielding structure of the present invention are respectively shown. It can be seen that the only difference between it and the first embodiment mentioned above is the different design structure of the shielding sheet 13, which is specifically manifested as follows: along the extension direction of the fixing portion 132, the first elastic contact portion 131 is sequentially connected by a first arc-shaped bending transition section 1315, a horizontal transverse section 1316 and a second right-leaning elastic contact claw 1317. The second elastic contact portion 133 is sequentially connected by a second arc-shaped bending transition section 1335, a right-leaning straight connecting section 1336 and a second left-leaning elastic contact claw 1337 (as shown in FIG. 1 ). Fig.19 , 20). By adopting the above technical solution, the first elastic contact portion 131 and the second elastic contact portion 133 can also be reliably pressed against the first mechanism housing 2 and the second mechanism housing 3 respectively, so that the Fakra connector 1 is always in a good shielding state during actual application. However, by comparing the above two embodiments horizontally, it can be seen that the first embodiment is suitable for the scene where the installation space of the Fakra connector 1 is large, while the second embodiment is suitable for the scene where the installation space of the Fakra connector 1 is relatively compact.

[0051] For the same purpose, similar to the design structure of the first right-leaning elastic contact claw 1314 and the first left-leaning elastic contact claw 1334, the number of the second right-leaning elastic contact claw 1317 is preferably set to be multiple and evenly distributed along the width direction of the horizontal transverse section 1316. The number of the second left-leaning elastic contact claw 1337 is also set to be multiple and evenly distributed along the width direction of the right-leaning straight connecting section 1336 (such as Fig.19 ).

[0052] Finally, as a further optimization of the above technical solution, opposite to the above first mechanism housing 2, a third arc-shaped bent contact segment 13171 may be provided on the second right-leaning elastic contact claw 1317. Fig.19 , 20 ).

[0053] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
