Detailed Description

In the description of the present invention, it is to be understood that the terms "left", "right", "upper", "lower", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

The present invention will be described in further detail with reference to specific examples, and fig. 1 and 2 respectively show a schematic structural diagram of a first embodiment of the shielding structure of the Fakra connector according to the present invention, and it is understood that the shielding structure mainly includes the Fakra connector 1, the first mechanism housing 2, and the second mechanism housing 3. The Fakra connector 1 is placed horizontally in a left-right orientation. The first mechanism housing 2 is laid across and arranged on the upper side of the Fakra connector 1. The second mechanism housing 3 is erected and arranged on the lower side of the Fakra connector 1. It should be noted that the first mechanism housing 2 and the second mechanism housing 3 are respectively a top plate and a side plate of the mechanism housing, and are named only for the convenience of the following description and drawings so as to facilitate those skilled in the art to fully understand the technical solution disclosed in the present invention.

Fig. 3 and 4 respectively show an exploded view and an assembled view of a Fakra connector according to a first embodiment of the shielding structure of the Fakra connector of the present invention, and it can be seen that the Fakra connector mainly comprises a metal conductive seat 11, an insulating plastic seat 12 and a shielding plate 13. The metal conductive seat 11 is inserted into the insulating plastic seat 12 from the right to the left. The shielding plate 13 is formed by sequentially connecting a first elastic contact portion 131, a fixing portion 132 and a second elastic contact portion 133 (as shown in fig. 8). The fixing portion 132 is clamped and fixed between the metal conductive seat 11 and the insulating plastic seat 12 (as shown in fig. 5 and 6). The first elastic contact portion 131 is formed by continuously extending the top wall of the fixing portion 132 and bending the top wall for multiple times, and is formed by sequentially connecting a first vertical connecting section 1311, a first right-inclined straight line transition section 1312, a second vertical connecting section 1313 and a first right-inclined elastic contact claw 1314. The first right-inclined elastic contact claw 1314 is used for elastically abutting against the first mechanism housing 2. The second elastic contact portion 133 is formed by continuously extending the bottom wall of the fixing portion 132 and bending the bottom wall for multiple times, and is formed by sequentially connecting a third vertical connection section 1331, a second right-inclined straight line transition section 1332, a fourth vertical connection section 1333 and a first left-inclined elastic contact claw 1334. Wherein the first left-leaning elastic contact claw 1334 is used for elastically abutting against the second mechanism housing 3 (as shown in fig. 8 and 9). Thus, the metal conductive seat 11 and the peripheral mechanism housing (i.e., the first mechanism housing 2 and the second mechanism housing 3) are ensured to be in an electrically conductive state, so that the Fakra connector 1 is always in a good shielding state in the actual application process, thereby effectively reducing the influence of external electromagnetic interference on the signal transmission process and ensuring the reliability and stability of signal transmission.

As a further optimization of the shielding structure of the Fakra connector, the number of the first right-inclined elastic contact claws 1314 is preferably set to be plural and uniformly distributed along the width direction of the second vertical connecting section 1313; the first left-inclined elastic contact claws 1334 are also preferably provided in plural number and are evenly distributed along the width direction of the fourth vertical connecting section 1333 (as shown in fig. 8 and 9). Thus, after the Fakra connector 1 is assembled in place with respect to the mechanism housing, the first right-inclined elastic contact claw 1314 and the first left-inclined elastic contact claw 1334 respectively realize elastic abutting against the first mechanism housing 2 and the second mechanism housing 3 in a multi-point contact manner, so that the reliability and the stability of the contact between the first right-inclined elastic contact claw 1314 and the first left-inclined elastic contact claw 1334 and the first mechanism housing 2 and the second mechanism housing 3 respectively are ensured, that is, the reliability of the electrical conduction between the shielding sheet 13 and the mechanism housing is ensured, and further, the Fakra connector 1 has good shielding performance in the practical application process.

As a further improvement of the technical solution of the present invention, the structure of the shielding plate 13 may be optimized as follows: opposite to the first mechanism housing 2, a first curved contact section 13141 is provided at the free end of the first right-leaning resilient contact finger 1314. Opposite to the second mechanism housing 3, a second curved contact segment 13341 (shown in fig. 8 and 9) is provided at the free end of the first left-leaning resilient contact finger 1334. The presence of the first arcuately bent contact section 13141 effectively eliminates the problem of scratching of its first right-angled resilient contact fingers 1314 during the course of performing the loading of the Fakra connector 1 into the mechanism housing; similarly, the presence of the second arcuately bent contact section 13341 effectively eliminates the problem of scoring of its first left-leaning resilient contact finger 133 as it is displaced relative to the second mechanism housing 3.

Generally, the Fakra connector 1 can achieve reliable clamping of the shield plate 13 in various ways, however, a simple design is proposed for positioning and assembling the shield plate 13, and the assembling efficiency is high, as follows: the metal conductive socket 11 is mainly composed of a metal conductive member 111, an insulating column 112, and a terminal 113. The metal conductive member 111 includes a conductive housing body 1111 and a plug-in post 1112. The inserting column 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 arranged in the inserting column. The connecting terminal 113 is inserted into and fixed to the insulating column 112, and is integrally disposed in the first accommodating chamber 11121. The metal conductive socket 11 is inserted and abutted with the insulating plastic socket 12 along the right-to-left direction by means of the insertion column 1112, and accordingly, a second accommodating cavity 121 is formed in the insulating plastic socket 12 for accommodating the insertion column 1112. The fixing portion 132 is sleeved on the inserting column 1112, and correspondingly, a through hole 1321 (as shown in fig. 4-6 and 8-13) is formed thereon and adapted to the shape of the inserting column 1112.

It should be noted that, in consideration of reducing the difficulty of assembling the shield 13 with respect to the plug 1112 and the stability after assembling, the fitting tolerance between the two is preferably a clearance fit, and the maximum unilateral clearance is controlled within 0.05 mm.

In addition, as a further optimization of the above technical solution, at least one limiting hole 1322 may be further formed on the fixing portion 132, and correspondingly, a limiting post 122 adapted to the limiting hole 1322 extends to the right along the right sidewall of the insulating plastic seat 12 (as shown in fig. 4, 5, 7, 8, and 11). By adopting the above technical solution, the shielding plate 13 can be effectively prevented from circumferential rotation motion relative to the plugging column 1112, and the first right-inclined elastic contact claw 1314 and the first left-inclined elastic contact claw 1334 on the shielding plate are ensured to reliably abut against the first mechanism housing 2 and the second mechanism housing 3, respectively, so as to ensure that the Fakra connector 1 has good shielding performance.

For the same purpose, a limiting protrusion 11122 may also be provided on the plugging column 1112. The limiting convex strips 11122 run along the left-right direction, the number of the limiting convex strips is at least 1, the limiting convex strips are uniformly distributed along the circumferential direction of the side wall of the plug-in post 1112, and correspondingly, at least 1 limiting notch 13211 matched with the limiting convex strips 11122 is formed around the circumferential side wall of the through hole 1321 (as shown in fig. 4, 5, 7, 8, 12, 13 and 14). By adopting the above technical solution, the phenomenon that the shielding plate 13 rotates circumferentially relative to the inserting column 1112 after being installed can be effectively avoided.

Of course, for the same purpose, the insulating plastic seat 12 may be provided with an escape notch 123 corresponding to the fixing portion 132. And the width dimension of the relief notch 123 corresponds to the width dimension of the securing portion 132 (as shown in fig. 2-6, 10, 11). By adopting the above technical solution, the phenomenon that the shielding plate 13 rotates circumferentially relative to the inserting column 1112 after being installed can be effectively avoided. In addition, the existence of the avoidance gap 123 can also effectively reduce the axial length dimension of the Fakra connector 1, so that the Fakra connector has a more compact design structure.

However, it should be noted that the above three solutions all have good application effects for solving the problem of the rotation of the shielding plate 13 relative to the insertion post 1112, so that those skilled in the art can select the solution according to the practical application scenario, the specific forming manner, and other factors in the process of implementing the structural design of the Fakra connector 1, and certainly, on the premise of neglecting the manufacturing and cost, the above three solutions can be tried on the same Fakra connector 1 at the same time to ensure that the Fakra connector 1 has more stable shielding performance.

Fig. 15 and 16 are schematic structural views and front views respectively showing a second embodiment of the shielding structure of the Fakra connector in the invention; fig. 17 and 18 show an exploded view of a Fakra connector and its three-dimensional assembly in a second embodiment of the shielding structure of the Fakra connector of the present invention, respectively, and it can be seen that the only difference between the first embodiment and the second embodiment is the difference in the design structure of the shielding plate 13, which is shown as follows: along the extension direction of the fixing portion 132, the first elastic contact portion 131 is formed by sequentially connecting a first curved transition section 1315, a horizontal transverse section 1316, and a second right-inclined elastic contact claw 1317. The second elastic contact portion 133 is formed by sequentially connecting a second arc-shaped bent transition section 1335, a right-inclined straight connecting section 1336 and a second left-inclined elastic contact claw 1337 (as shown in fig. 19 and 20). Through adopting above-mentioned technical scheme to set up, can realize first elastic contact portion 131, second elastic contact portion 133 respectively to the reliable top of first mechanism shell 2, second mechanism shell 3 similarly and lean on, and then make Fakra connector 1 be in good shielding state throughout its self in practical application. However, as can be seen from a lateral comparison of the above two embodiments, the first embodiment is suitable for a scene in which the installation space of the Fakra connector 1 is large, while the second embodiment is suitable for a scene in which the installation space of the Fakra connector 1 is compact.

For the same purpose, the second right-inclined resilient contact fingers 1317 are preferably provided in plural numbers and are uniformly distributed along the width direction of the horizontal cross section 1316, similar to the first right-inclined resilient contact fingers 1314 and the first left-inclined resilient contact fingers 1334. The second left-inclined resilient contact claws 1337 are also provided in plural number and are evenly distributed in the width direction of the right-inclined straight line connection section 1336 (as shown in fig. 19).

Finally, as a further optimization of the above technical solution, a third curved contact segment 13171 may be further disposed on the second right-leaning resilient contact finger 1317, opposite to the first mechanism housing 2. Opposite to the second mechanism housing 3, a fourth curved contact segment 13371 (shown in fig. 19 and 20) may be further provided on the second left-leaning resilient contact finger 1337.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
