Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive rearview mirror technology, and in particular to a MINI FAKRA connector with waterproof function. Background Technology
[0002] The MINI FAKRA connector is a miniaturized version of the FAKRA connector. Developed by Rosenberger and standardized by the German Association of Automotive Manufacturers, the FAKRA connector is a version of the ultra-miniature Type B (SMB) coaxial RF connector, widely used in automotive electronics for two decades. With the continuous miniaturization of electronic devices and the increasing demand for high-speed signal transmission, the MINI FAKRA connector was developed to meet the requirements of more compact space and higher performance. Its interface design features a rectangular shape conforming to specific standards, a locking mechanism, and provides a stable connection, preventing signal interruption or interference.
[0003] One existing MINI FAKRA connector has a double-clamp structure. Due to limited internal space on the side of the connector and short clamps, uneven force distribution makes it prone to damage, resulting in insufficient pull-out force between the wire and the connector. Furthermore, it lacks a waterproof structure and is not waterproof. In other words, this type of connector in the existing technology is not only not waterproof, but also has insufficient clamping force and is prone to breakage. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a MINI FAKRA connector with waterproof function.
[0005] This utility model is achieved using the following technical solution: a waterproof MINI FAKRA connector, comprising a plastic shell, a fixed upright plate fixedly connected to the top of the plastic shell, a mounting buckle fixedly connected to the top of the plastic shell, a connecting block fixedly connected to the surface of the plastic shell, a fixed cover plate snapped to the rear end of the plastic shell, a mounting shell snapped to the front end of the plastic shell, a fixed buckle inserted into the front end of the plastic shell, a mounting groove provided inside the mounting shell, a first waterproof ring inserted into the surface of the fixed buckle, a mounting ring fixedly connected inside the plastic shell, a connector inserted into the inside of the mounting ring, and a second waterproof ring inserted into the rear end surface of the connector.
[0006] With the above technical solution, the mounting clip is located at the rear end of the mounting housing, which can firmly fix the mounting housing to the plastic housing, prevent the mounting housing from loosening, and further ensure the stability of the overall connector structure.
[0007] As a further improvement to the above solution, the number of fixed uprights is set to two, and the two fixed uprights are symmetrically distributed on the left and right sides with the plastic shell as the center, and the second waterproof ring is located inside the plastic shell.
[0008] As a further improvement to the above solution, the number of connecting blocks is set to several, and the several connecting blocks are evenly distributed around the plastic shell as the center, and the surface of the connecting blocks is in contact with the surface of the fixed cover plate.
[0009] Through the above technical solution, there are several connecting blocks that are evenly distributed around the plastic shell. Their surfaces are in contact with the surface of the fixed cover plate. The evenly distributed connecting blocks allow the fixed cover plate to be tightly snapped into the rear end of the plastic shell, thereby enhancing the sealing performance and structural stability of the rear end of the plastic shell.
[0010] As a further improvement to the above solution, the fixing buckle is inserted into the inside of the mounting groove, the fixing buckle is inserted into the inside of the mounting shell, and the first waterproof ring is located inside the plastic shell.
[0011] With the above technical solution, there are two fixed upright plates, which are symmetrically distributed on the left and right sides with the plastic shell as the center. Their surfaces are in contact with the surface of the mounting shell, providing stable support for the mounting shell and preventing the mounting shell from shaking or shifting during use, thus ensuring the stability of the overall connector structure.
[0012] As a further improvement to the above solution, the first waterproof ring is inserted into the inside of the mounting groove, the first waterproof ring is inserted into the inside of the mounting housing, and the connector is inserted into the inside of the plastic housing.
[0013] As a further improvement to the above solution, the surface of the fixed upright plate is in contact with the surface of the mounting shell, and the mounting buckle is located at the rear end of the mounting shell.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] This invention modifies the buckle structure and embedding method, changing the double buckle structure to an integral structure. It also changes the traditional side-embedding method of the double buckles, replacing it with an interface-level embedding. This integral interface-level embedding method increases the force-bearing area of the buckles and enhances the pull-out force between the housing and the plastic outer shell. This increased pull-out force effectively prevents the wire from detaching from the connector due to insufficient pull-out force, thus increasing the connector's lifespan. Furthermore, to meet usage scenarios in more environments, the modified connector structure and the addition of a waterproof ring enable this invention to meet waterproof requirements, broadening its applicability.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0024] Example:
[0025] Please combine Figure 1-5 This embodiment features a waterproof MINI. The FAKRA connector includes a plastic shell 1, a fixed plate 2 fixedly connected to the top of the plastic shell 1, a mounting buckle 3 fixedly connected to the top of the plastic shell 1, a connecting block 4 fixedly connected to the surface of the plastic shell 1, a fixed cover plate 5 snapped to the rear end of the plastic shell 1, a mounting shell 6 snapped to the front end of the plastic shell 1, a fixing buckle 7 inserted into the front end of the plastic shell 1, a mounting groove 8 opened inside the mounting shell 6, a first waterproof ring 9 inserted into the surface of the fixing buckle 7, a mounting ring 11 fixedly connected inside the plastic shell 1, a connector 10 inserted into the inside of the mounting ring 11, and a second waterproof ring 12 inserted into the rear end surface of the connector 10. By modifying the buckle structure and embedding method, the double buckle structure is changed to an integral structure, and the side embedding is changed to an interface embedding, increasing the force-bearing area of the buckle and increasing the pull-out force between the shell and the plastic shell 1. By modifying the connector structure and adding a waterproof ring, the waterproof requirements are met. The traditional double buckle side embedding method is changed to an integral embedding from the interface, and a waterproof ring is added to the original structure.
[0026] The mounting clip 3 is located at the rear end of the mounting housing 6, which can firmly fix the mounting housing 6 to the plastic housing 1, prevent the mounting housing 6 from loosening, and further ensure the stability of the overall connector structure.
[0027] The number of fixed uprights 2 is set to two, and the two fixed uprights 2 are symmetrically distributed on the left and right sides with the plastic shell 1 as the center. The second waterproof ring 12 is located inside the plastic shell 1.
[0028] The number of connecting blocks 4 is set to several, and the several connecting blocks 4 are distributed equidistantly around the plastic shell 1. The surface of the connecting blocks 4 is in contact with the surface of the fixed cover plate 5.
[0029] The number of connecting blocks 4 is several and they are evenly distributed around the plastic shell 1. Their surfaces are in contact with the surface of the fixing cover plate 5. The evenly distributed connecting blocks 4 allow the fixing cover plate 5 to be tightly clamped to the rear end of the plastic shell 1, which enhances the sealing and structural stability of the rear end of the plastic shell 1.
[0030] The fixing buckle 7 is inserted into the inside of the mounting slot 8 and the mounting housing 6. The first waterproof ring 9 is located inside the plastic housing 1.
[0031] There are two fixed upright plates 2, which are symmetrically distributed on the left and right sides with the plastic shell 1 as the center. Their surfaces are in contact with the surface of the mounting shell 6, providing stable support for the mounting shell 6 and preventing the mounting shell 6 from shaking or shifting during use, thus ensuring the stability of the overall connector structure.
[0032] The first waterproof ring 9 is inserted into the inside of the mounting slot 8 and the first waterproof ring 9 is inserted into the inside of the mounting housing 6. The connector 10 is inserted into the inside of the plastic housing 1. By setting the overall equipment, the pull force of the connector is enhanced, which effectively avoids the hidden danger of the wire coming off the connector due to insufficient pull force and increases the service life of the connector. At the same time, in order to meet the usage scenarios in more environments, a new waterproof structure has been designed, which has a wider range of applications.
[0033] The surface of the fixed upright plate 2 is in contact with the surface of the mounting housing 6, and the mounting buckle 3 is located at the rear end of the mounting housing 6.
[0034] The implementation principle of this embodiment is as follows: by modifying the buckle structure and embedding method, the double buckle structure is changed to an integral structure, and the side embedding is changed to the interface embedding, which increases the force-bearing area of the buckle and increases the pull-out force between the shell and the plastic outer shell 1. By modifying the connector structure and adding a waterproof ring, the waterproof requirements are met.
[0035] This embodiment changes the traditional double-buckle side-embedding method to an overall embedding method from the interface. This overall embedding method enhances the pull-out force of the connector, effectively avoiding the risk of the wire coming off the connector due to insufficient pull-out force, and increasing the service life of the connector. At the same time, in order to meet the usage scenarios in more environments, a new waterproof structure has been designed on the original structure. The waterproof structure makes this embodiment waterproof and has a wider range of applications.
[0036] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
