In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "left", "right", "upper", "lower", etc. is based on the orientation or positional relationship shown in the accompanying drawings, only for the purpose of It is convenient to describe the present invention and to simplify the description, rather than indicating or implying that the device or element referred to must have a particular orientation, be constructed and operate in a particular orientation, and therefore should not be construed as limiting the invention.

The content of the present invention will be further described in detail below with reference to specific examples. Figures 1 and 2 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 the Fakra connector 1 , the first mechanism casing 2 and the second mechanism casing 3 are constituted. Fakra connector 1 is placed horizontally along the left and right directions. The first mechanism housing 2 is laid horizontally and arranged on the upper side of the Fakra connector 1 . The second mechanism housing 3 is placed vertically, and is arranged on the lower side of the Fakra connector 1 . It should be noted here that the above-mentioned first mechanism shell 2 and second mechanism shell 3 are the top plate and side plate of the mechanism shell, respectively, and these names are only for the convenience of the following description and view representation, so that those skilled in the art can fully Understand the technical solutions disclosed in the present invention.

3 and 4 respectively show the exploded schematic diagram and the assembly diagram of the Fakra connector in the first embodiment of the Fakra connector shielding structure of the present invention. It can be seen that it mainly consists of a metal conductive seat 11, an insulating plastic seat 12 and a shielding sheet 13 Compositions. The metal conductive seat 11 is inserted into the insulating plastic seat 12 along the direction from right to left. The shielding sheet 13 is formed by sequentially connecting the first elastic contact portion 131 , the fixing portion 132 and the second elastic contact portion 133 (as shown in FIG. 8 ). The fixing portion 132 is clamped and fixed between the metal conductive base 11 and the insulating plastic base 12 (as shown in FIGS. 5 and 6 ). The first elastic contact portion 131 is formed by continuing to extend from the top wall of the fixing portion 132 and being bent multiple times. 1313 and the first right-inclined elastic contact claw 1314 are connected. The first right-inclined elastic contact claw 1314 is used for elastically abutting against the above-mentioned first mechanism housing 2 . The second elastic contact portion 133 is formed by continuing to extend from the bottom wall of the fixing portion 132 and being bent multiple times, and is formed by the third vertical connecting section 1331 , the second right-inclined linear transition section 1332 , and the fourth vertical connecting section in sequence.

The first left-leaning elastic contact claw 1334 is used to elastically abut against the second mechanism housing 3 (as shown in FIGS. 8 and 9 ). In this way, it is ensured that the metal conductive base 11 and the peripheral mechanism casing (ie the first mechanism casing 2 and the second mechanism casing 3 mentioned above) are kept in an electrical conduction state, thereby making the Fakra connector 1 itself in the actual application process. It is always in a good shielding state, which can effectively reduce the impact of external electromagnetic interference on the signal transmission process, and ensure the reliability and stability of signal transmission.

As a further optimization of the above-mentioned Fakra connector shielding structure, the number of the above-mentioned first right-inclined elastic contact claws 1314 should be set to multiple, and they are evenly distributed along the width direction of the second vertical connection section 1313; the above-mentioned first left-inclined elastic contact The number of the claws 1334 is also preferably set to be multiple and uniformly distributed along the width direction of the fourth vertical connection section 1333 (as shown in FIGS. 8 and 9 ). In this way, after the Fakra connector 1 is assembled in place relative to the mechanism housing, the first right-inclined elastic contact claw 1314 and the first left-inclined elastic contact claw 1334 are in multi-point contact with the first mechanism housing 2 respectively. , the elastic abutment of the second mechanism housing 3, thereby ensuring the reliability and stability of the first right-inclined elastic contact claw 1314 and the first left-inclined elastic contact claw 1334 respectively contacting the first mechanism shell 2 and the second mechanism shell 3, That is, the reliability of the electrical conduction between the shielding sheet 13 and the mechanism housing is ensured, thereby ensuring that the Fakra connector 1 has good shielding properties during practical application.

Furthermore, as a further improvement of the technical solution of the present invention, the structure of the shielding sheet 13 can also be optimized as follows, as follows: opposite to the above-mentioned first mechanism housing 2, at the free end of the first right-inclined elastic contact claw 1314 A first arc-shaped bending contact segment 13141 is provided. Opposite to the above-mentioned second mechanism housing 3, a second arc-shaped bending contact segment 13341 (as shown in FIGS. 8 and 9 ) is provided at the free end of the first left-inclined elastic contact claw 1334 . During the process of installing the Fakra connector 1 into the mechanism housing, the existence of the first arc-shaped bending contact segment 13141 can effectively prevent the first right-inclined elastic contact claw 1314 from being displaced relative to the first mechanism housing 2 In the same way, the existence of the second arc-shaped bending contact segment 13341 can effectively prevent the first left-inclined elastic contact claw 133 from being scratched during displacement relative to the second mechanism housing 3 .

Generally speaking, the Fakra connector 1 can use a variety of methods to achieve reliable clamping of the shielding sheet 13, however, a simple structure design is recommended here, which is convenient for positioning and assembling the shielding sheet 13, and has high assembly efficiency The design structure is as follows: the metal conductive seat 11 is mainly composed of several parts such as a metal conductive member 111 , an insulating column 112 and a connection terminal 113 . The metal conductive member 111 includes a conductive shell body 1111 and an insertion post 1112 . The plug-in post 1112 is formed by extending the left side wall of the conductive shell body 1111 to the left, and a first accommodating cavity 11121 is disposed therein. The connection 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 inserted and butted with the insulating plastic seat 12 along the right-to-left direction by means of the above-mentioned inserting posts 1112. Correspondingly, a second accommodating cavity 121 is provided in the insulating plastic seat 12 for inserting the above-mentioned insulating plastic seat 12. Insertion post 1112 . The fixing portion 132 is sleeved on the plug-in post 1112 , and correspondingly, there is a through hole 1321 (as shown in FIGS. 4-6 and 8-13 ) which is adapted to the shape of the plug-in post 1112 . .

It should be noted here that, considering the comprehensive reduction of the difficulty of assembling the shielding sheet 13 relative to the plug-in post 1112 and the stability after assembly, the fit tolerance between the two is preferably clearance fit, and the maximum unilateral gap is controlled at 0.05mm within.

In addition, as a further optimization of the above-mentioned technical solution, at least one limiting hole 1322 may be opened on the fixing portion 132 . Correspondingly, along the right side wall of the insulating plastic seat 12 , there is a limit hole corresponding to the above-mentioned limiting hole extending to the right. 1322 to fit the limit post 122 (as shown in Figures 4, 5, 7, 8, 11). By adopting the above technical solution, the shielding sheet 13 can be effectively prevented from rotating in the circumferential direction relative to the plug-in post 1112, and the first right-inclined elastic contact claw 1314 and the first left-inclined elastic contact claw 1334 on the shielding sheet 13 can be effectively prevented from rotating to the first mechanism respectively. The housing 2 and the housing 3 of the second mechanism are reliably abutted, so as to ensure that the Fakra connector 1 has good shielding performance.

For the same purpose as mentioned above, a limiting protruding strip 11122 may also be provided on the plug-in column 1112 . The limiting protruding strips 11122 run along the left-right direction, the number of which is set to at least one, and is uniformly distributed along the side wall of the insertion column 1112. Correspondingly, there are at least 1 There are two limiting notches 13211 (as shown in FIGS. 4 , 5 , 7 , 8 , 12 , 13 , and 14 ) matching with the limiting protruding strips 11122 . By adopting the above technical solution for setting, the phenomenon of circumferential rotation of the shielding sheet 13 relative to the plug-in post 1112 after installation can also be effectively prevented.

Of course, for the same purpose as described above, the insulating plastic seat 12 may also be provided with an escape notch 123 corresponding to the above-mentioned fixing portion 132 . And the width dimension of the avoidance notch 123 is the same as that of the fixing portion 132 (as shown in FIGS. 2-6 , 10 and 11 ). By adopting the above technical solution for setting, the phenomenon of circumferential rotation of the shielding sheet 13 relative to the plug-in post 1112 after installation can also be effectively prevented. In addition, avoiding the existence of the notch 123 can also effectively reduce the axial length dimension of the Fakra connector 1, so that it has a more compact design structure.

However, it should be noted here that the above three solutions all have good application effects in solving the problem of the rotation of the shielding sheet 13 relative to the insertion post 1112. Therefore, those skilled in the art are in the process of implementing the structural design of the Fakra connector 1. It can be selected according to the actual application scene, specific molding method and other factors. Of course, under the premise of ignoring the manufacturing and cost, the above three schemes can also be tried on the same Fakra connector 1 at the same time to ensure that the Fakra connector 1 has better performance. for stable shielding performance.

Figures 15 and 16 respectively show a schematic structural diagram and a front view of the second embodiment of the Fakra connector shielding structure of the present invention; Figures 17 and 18 respectively show the second embodiment of the Fakra connector shielding structure of the present invention The exploded schematic diagram of the Fakra connector and its three-dimensional assembly in the method, it can be seen that the only difference between the Fakra connector and the above-mentioned first embodiment is the design structure of the shielding sheet 13. The specific performance is as follows: along the extension direction of the fixed 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-inclined elastic contact claw 1317 . The second elastic contact portion 133 is sequentially connected by a second arc-shaped bending transition section 1335 , a right-inclined linear connecting section 1336 and a second left-inclined elastic contact claw 1337 (as shown in FIGS. 19 and 20 ). By adopting the above technical solutions, the first elastic contact portion 131 and the second elastic contact portion 133 can also be reliably abutted against the first mechanism housing 2 and the second mechanism housing 3 respectively, thereby making the Fakra connector 1 practical in practice. It is always in a well-shielded state during the application process. However, a horizontal comparison of the above two embodiments shows that the first embodiment is suitable for a scenario where the installation space of the Fakra connector 1 is relatively large, while the second embodiment is suitable for a scenario where the installation space for the Fakra connector 1 is relatively compact.

For the same purpose, analogous to the design structures of the first right-inclined elastic contact claws 1314 and the first left-inclined elastic contact claws 1334, the number of the second right-inclined elastic contact claws 1317 should be set in multiples along the horizontal horizontal section. The width direction of 1316 is uniformly distributed. The number of the second left-inclined elastic contact claws 1337 is also set in multiples, and is uniformly distributed along the width direction of the right-inclined linear connecting section 1336 (as shown in FIG. 19 ).

Finally, as a further optimization of the above technical solution, contrary to the above-mentioned first mechanism housing 2 , a third arc-shaped bending contact segment 13171 may also be provided on the second right-inclined elastic contact claw 1317 . Contrary to the above-mentioned second mechanism housing 3 , a fourth arc-shaped bending contact segment 13371 (as shown in FIGS. 19 and 20 ) may also be provided on the second left-inclined elastic contact claw 1337 .
