Description

Technical Field

[0001] This application relates to the technical field of connectors, and particularly to a mini Fakra connector. Background Art

[0002] With the technological transformation of the automotive industry, automotive automation and intelligence have become the future development trends. Among them, automotive imaging has become an essential configuration for realizing automation and intelligence. Currently, most in-vehicle cameras used in automobiles have unclear, blurred or even failed functions in some harsh environments. Especially in rainy and foggy weather, the lens of the camera is prone to fogging, resulting in unclear and blurred imaging on the central control, which undoubtedly poses a great safety hazard. Therefore, some automobiles have begun to add a heating module to the camera module. When driving in rainy and foggy weather, the driver turns on the heating power supply, and the defogging function is realized by heating the camera module. However, in order to supply power to the heating module, a mini fakra connector is required to integrate the radio frequency terminal and the high-current power terminal.

The first cable 401 is electrically connected to the high-speed signal propagation connector 403. The two second cables 402 are respectively electrically connected to the two current connectors 404.

[0033] When the first connecting seat 12 is plugged into the second connecting seat 13, the cable assembly separates two signals for independent current transmission and integrates the signals and current on one connector, while performing physical isolation to prevent crosstalk.

[0034] Further, referring to Figures 1 - 6, on the outer wall at one end of the circumference of the first connecting seat 12, a number of elastic connecting blocks 501 are fixedly installed at equal intervals.

On both sides of the first connecting seat 12, elastic support blocks 502 are fixedly installed. The two elastic support blocks 502 are respectively arranged corresponding to the two openings two 904.

[0035] Insert the first connecting seat 12 into the second connecting seat 13, so that a number of elastic connecting blocks 501 are correspondingly inserted into the slots 903. At the same time, make the two elastic support blocks 502 respectively move into the two openings two 904, completing the fixation of the insertion of the first connecting seat 12 and the second connecting seat 13, effectively preventing loosening and displacement during use, and enhancing the sealing effect of the second sealing component.

[0038] Further, referring to Figures 1 - 3 and Figures 5 - 6 , on the top of the other side of the first male connector 1, an opening four is provided. On the other side of the top of the first male connector 1, an opening five is provided. On the inner wall of the bottom of the opening four, a sliding plate 701 is slidably installed.

[0039] After the equipment box body 601 is installed, align the sliding plate 701 with the elastic groove plate 704 through the mounting block 702 and then insert it, making the combination of the first male connector 1 and the equipment box body 601 more compact, effectively preventing relative displacement or loosening caused by external forces during use.

[0041] During the use of the connector, when transmitting large currents, heat is concentrated, which easily causes material aging. The heat dissipation groove 905 dissipates heat from the male connector 1.

[0042] Working principle: First, after the female connector 11 is inserted into the male connector 2 10, several sealing gaskets 1 201 are in close contact with the inner wall of the circumferential support ring 202 to prevent water droplets from penetrating through the gap between the male connector 2 10 and the female connector 11. Subsequently, the connecting seat 1 12 is inserted into the connecting seat 2 13, so that several elastic connecting blocks 501 are correspondingly inserted into the slots 903, and at the same time, two elastic support blocks 502 are respectively moved into the two openings 2 904 to complete the fixation of the insertion of the connecting seat 1 12 and the connecting seat 2 13, effectively preventing loosening and displacement during use, enhancing the sealing effect of the sealing component 2. The cable assembly separates two signals for independent current transmission and integrates the signals and current on one connector, while performing physical isolation to prevent crosstalk. The circular edge of the sealing plate 1 301 closely adheres to the inner wall of the circumferential connecting seat 1 12. One end of the sealing ring 303 close to the connecting seat 2 13 closely adheres to one side of the sealing plate 1 301 close to the connecting seat 1 12. The inner wall of the circumferential sealing ring 303 closely adheres to the circular edge of the sealing plate 2 302 to prevent water droplets from penetrating through the cable gap. After the equipment box 601 is installed, the sliding plate 701 is inserted into the elastic groove plate 704 after aligning it with the installation block 702 through the installation block 702, making the male connector 1 more closely combined with the equipment box 601, effectively preventing relative displacement or loosening caused by external forces during use. Through the setting of structures such as the buffer spring 703, when the equipment is subjected to vibration and impact, it can play a buffer protection role, achieving physical isolation of signals and current in one connector to prevent crosstalk, and at the same time improving the waterproof effect of the insertion part of the connector.
