Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted controller signal ports, in particular to a novel miniFaKra connector. Background Art

[0002] Automotive coaxial connectors are primarily used for high-frequency data and signal transmission. They must exhibit strong resistance to electromagnetic interference, meet the requirements of miniaturization, high sealing and shielding performance, and comply with automotive standards and specifications. For example, they are used in automotive millimeter-wave radar, lidar, cameras, and sensors to enable functions such as assisted driving and parking.

[0003] Mini FaKra connectors are available in both board-mounted and standard types. However, existing automotive connectors suffer from a poor balance between vibration and shock resistance, plug-in and pull-out force controllability, and shielding performance, leading to user inconvenience. For example, the cylindrical male and female terminals provide excellent interface signal shielding performance after connection, but their vibration and shock resistance and plug-in board controllability are poor. This is because they rely primarily on the plug-in force of the male and female metal terminals to achieve a tight fit. If the plug-in relies on the snap-fit ​​structure of the male and female barrels, plugging and unplugging can be difficult or the cable's tight fit can be insufficient, which can easily cause the cable to detach from the connector. Sufficient retention force is required between the cable and the connector to prevent detachment.

[0004] Therefore, there is an urgent need for a new mini FaKra connector that can solve one or more of the above problems. Utility Model Content

The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] The utility model discloses a new mini FaKra connector, which includes: Figure 1-Figure 3 As shown, the female connector assembly A1 is provided with a female connector body 1, the lower end of the female connector body 1 is a first docking portion 10, the upper end of the female connector body 1 is fastened to the female connector insulator 3, the female connector insulator 3 is installed with a female connector terminal 2, and the upper end of the female connector terminal 2 is provided with at least two clamping springs 20;

[0034] The lower end of the female outer conductor 4 is inserted into the upper end of the female body 1 and is fastened to the female insulator 3. The upper end of the female outer conductor 4 is formed with at least two interlocking thin-walled spring clips 40. A gap 41 is formed between adjacent interlocking thin-walled spring clips 40 to disconnect them. The outer side walls of the interlocking thin-walled spring clips 40 are provided with fastening flanges 402. The interlocking thin-walled spring clips 40 are provided with hollow grooves 401 to avoid the fastening flanges 402.

[0035] The female connector fastener 5 presses the braided conductor 60 of the cable 6 against the outer wall of the first docking portion 10 , and the core wire 61 of the cable 6 passes into the female connector body 1 and is electrically connected to the female connector terminal 2 ;

[0036] Male connector, combined Figure 4-Figure 6As shown, the male connector assembly A2 is provided with a male connector body 7, the lower end of the male connector body 7 is a second docking portion 70, the upper end of the male connector body 7 is fastened to a male connector insulator 8, and the male connector insulator 8 is equipped with a male connector pin 9;

[0038] Combine Figure 7-Figure 8 As shown, when the female component A1 is docked with the male component A2, the plug-in thin-walled spring piece 40 is inserted into the upper end of the male body 7, the fastening flange 402 is in contact with the inner side wall of the male body 7, the upper end portion of the male insulator 8 is inserted into the plug-in thin-walled spring piece 40, the male pin 9 is inserted into the female insulator 3, and the clamping spring piece 20 clamps the male pin 9. After the female component A1 and the male component A2 are docked, the male body 7 is connected to the female body 1 or only a small gap is left, thereby forming a fully enclosed channel, thereby improving the shielding effectiveness of the connector and the cable.

[0039] It should be pointed out that, combined with Figure 3 、 Figure 6 As shown, to facilitate the mating of the male connector assembly A2 and the female connector assembly A1, the top end of the female connector outer conductor 4 is retracted inward, and a corresponding chamfer or guide surface is provided on the inner side of the mating port of the male connector body 7. Similarly, to facilitate the insertion of cables, chamfers or guide surfaces are provided on the ports of the female connector body 1 and the male connector body 7 that mate with the cables.

[0040] Specifically, combined Figure 1 、 Figure 4 As shown, the outer wall of the female connector body 1 is provided with a first anti-rotation flange 12, and the outer wall of the male connector body 7 is provided with a second anti-rotation flange 72. The first and second anti-rotation flanges cooperate with the corresponding external housing to prevent the connector from rotating during use due to external impact or micro-vibration of the spring, thereby ensuring the stability of the connection.

[0046] An isolation flange 82 is formed on the outer side wall of the male insulator 8. The isolation flange 82 is provided on the upper side of the connecting flange 81 and is tightly connected to the inner side wall of the male body 7.

[0047] The second connecting portion 80 and the connecting flange 81 improve the connection firmness of the male insulator 8 in the male body 7. The segmented design also facilitates insertion and segmented isolation. Compared with the single-segment design, it can effectively avoid the arching of the single segment causing some points to be unable to contact; the isolation flange 82 provides a certain degree of waterproof and dustproof performance, and provides a limit for the female outer conductor 4 during insertion.

[0048] To sum up, the present application surrounds and wraps the female insulator with plug-in thin-walled spring sheets, so that the interface signal shielding efficiency of the female component and the male component can be improved after plugging in, and full shielding can be achieved. The plug-in structure formed by the plug-in thin-walled spring sheets, the male body, and the male insulator can improve the contact stability of the female component and the male component after plugging in, thereby better resisting the vibration impact force of the vehicle; among them, the hollow groove enables the plug-in thin-walled spring sheet itself to form multiple spring sheet structures, and the fastening flange is located on this spring sheet structure, thereby obtaining multiple contact points with larger widths, thereby improving the firmness of the plug-in and ensuring the stability and controllability of the plug-in and pull-out force.
