Description

Technical Field

[0001] The utility model relates to the technical field of electrical component connectors, in particular to a small high-speed signal transmission adapter. Background Art

[0002] With the rapid evolution of modern automotive technology, in-vehicle high-definition cameras have become one of the core components for improving driving safety and realizing advanced driver assistance systems (ADAS) and even vehicle autonomous driving. These cameras are not only used for traditional reversing images, but are also widely used in a variety of safety and convenience functions such as 360-degree surround monitoring, lane keeping assist, and collision warning systems. With the continuous advancement of technology, the resolution of cameras is increasing to meet the needs of more sophisticated perception of the surrounding environment, which directly leads to a significant increase in data transmission volume and puts higher requirements on the performance of data connectors.

[0003] Traditionally, Fakra connectors have been widely used in vehicle environments to support data transmission of high-definition cameras due to their good electromagnetic compatibility and high reliability. However, with the in-depth development of automotive intelligence, especially for the real-time processing and analysis of high-definition video streams, the original Fakra connectors have gradually shown limitations in data transmission speed and signal integrity. To meet this challenge, the Mini Fakra connector came into being. With its smaller size, higher data transmission rate (up to 20Gbps) and wider operating frequency (up to 9GHz), it effectively reduces the loss in the signal transmission process and meets the needs of the new generation of vehicle-mounted camera systems for high-speed data transmission.

[0004] However, although the Mini Fakra connector meets the requirements of high-speed data transmission in terms of technical performance, its miniaturized design has encountered new bottlenecks in practical applications. Due to the limited size of the camera, it is impossible to mate with the existing Mini Fakra connector. Utility Model Content

[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0041] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0042] See also Figure 1-5 , Figure 16-18 The utility model provides a small high-speed signal transmission adapter, comprising:

[0043] A conductor assembly, the conductor assembly comprising a central conductor (1) and an insulator (2), wherein the central conductor (1) is sleeved in the insulator (2) and penetrates the insulator (2);

[0044] An outer conductor adapter (3), the conductor assembly is sleeved on the outer conductor adapter (3) and penetrates the outer conductor adapter (3), and the center conductor (1) and the outer conductor adapter (3) are insulated from each other by an insulator (2);

[0045] The flange outer shell (5) comprises a front end plug-in portion (51), a rear end plug-in portion (52) and a plug-in hole (53), wherein the plug-in hole (53) of the flange outer shell (5) penetrates the front end plug-in portion (51) and the rear end plug-in portion (52);

[0046] The outer guide adapter (3) is sleeved in the plug-in hole of the flange outer shell (5);

[0047] The central conductor (1) has a first connection terminal (11) and a second connection terminal (12);

[0048] At the front end plug-in portion (51), the front end of the external conductor adapter (3) is fixed to the board-end connector (6), so that the first connection terminal (11) of the central conductor (1) is electrically connected to the board-end connector (6);

[0049] The rear end plug-in portion (52) and the line end connector (7) are fixed to electrically connect the second connection terminal (12) of the center conductor (1) and the line end connector (7).

[0050] Furthermore, the line-end connector refers to the minifakra connector, and the board-end connector refers to the signal transmission connection end on the camera module. A minifakra adapter is established to achieve matching between the minifakra connector and the camera.

[0051] The adapter designed by the utility model can not only meet the needs of high-speed data transmission, but also adapt to the new generation of connectors with the trend of miniaturization of vehicle-mounted cameras. While ensuring efficient data transmission, it optimizes its physical structure and achieves seamless connection with various compact camera modules, thereby promoting the further development of automotive intelligent technology.

[0052] See also Figure 12-15 Furthermore, the flange outer shell (5) has a fixing plate (54), and the fixing plate (54) is provided with a flange hole (541).

[0053] The adapter is fixed to the camera head cover by means of screw connection through the flange hole (541) on the fixing plate (54).

[0054] See also Figure 6-7 Furthermore, the first connecting terminal (11) of the central conductor (1) has an axial slot (111), and the second connecting terminal (12) is in the shape of a pin.

[0055] The adapter is fixed to the top cover of the camera, the first connection terminal (11) of the central conductor (1) is connected to the board-end connector (6) of the camera, and the second connection terminal (12) is connected to the line-end connector, i.e., the minifakra connector, to achieve docking between the board-end connector (6) and the line-end connector, thereby enabling signal transmission between the camera and the minifakra connector.

[0056] Furthermore, the central conductor (1) adopts a phosphor bronze substrate, and the first connecting terminal (11) and the second connecting terminal (12) are plated with gold elements. The connecting terminals are plated with gold elements to enhance the high-frequency performance of the conductor.

[0057] Furthermore, the middle section of the central conductor (1) connecting the first connecting terminal (11) and the second connecting terminal (12) is plated with nickel.

[0058] Furthermore, the central conductor (1) and the insulator (2) are interference fit.

[0059] Furthermore, the second connection terminal (12) connected to the center conductor (1) exposes the insulator (2). That is, the insulator (2) does not wrap around the second connection terminal (12), so that the pin-shaped second connection terminal (12) can be connected to the line end connector.

[0060] Furthermore, at least one circle of annular barbs (13) is provided on the middle section of the central conductor (1) that connects the first connecting terminal (11) and the second connecting terminal (12).

[0061] Once the center conductor (1) is inserted into the insulator, the annular barb (13) structure will "bite" into the wall surface of the inner hole of the insulator, thereby providing additional mechanical resistance and preventing the center conductor (1) from accidentally coming out when subjected to axial force or torque, which can effectively improve the stability and reliability of the socket. In addition, the annular barb (13) structure can also disperse stress distribution and protect the interference fit surface from damage caused by excessive local pressure, which is beneficial to extending the service life of the component. It can be seen that the annular barb can enhance the firmness of the socket connection between the center conductor and the insulator and prevent relative sliding.

[0062] See also Figure 10-11 Furthermore, the insulator (2) and the outer conductive adapter (3) are interference-fitted, and the rear end surface of the outer conductive adapter (3) is provided with a first chamfer (31) that matches the insulator (2).

[0063] A chamfer that matches the insulator is designed at the assembly position to facilitate the sleeve assembly of the external conductive adapter and the insulator.

[0064] See also Figure 8-9 The rear end of the insulator (2) is provided with an annular protrusion (21); the rear end face of the external conductive adapter (3) contacts the front end face of the annular protrusion (21) at the rear end of the insulator (2), and the rear end face of the external conductive adapter (3) is provided with a first chamfer (31) that matches the insulator.

[0065] The first chamfer can make it easier to align and insert the insulator (2) and the outer conductive adapter (3) during sleeve assembly, thereby reducing assembly resistance, making the assembly process smoother, saving assembly time and improving assembly efficiency.

[0066] Furthermore, the material of the external conductor adapter (3) is lead brass plated with nickel, which meets the requirements of a 96-hour neutral salt spray test. The external conductor adapter (3) is mainly used for grounding.

[0067] Furthermore, the flange outer shell (5) and the outer guide adapter (3) are interference fit, and the rear end face of the outer guide adapter (3) is provided with a second chamfer (32) that matches the flange outer shell (5).

[0068] The second chamfer can make it easier to align and insert the flange outer shell (5) and the outer guide adapter (3) during sleeve assembly, which can reduce assembly resistance, make the assembly process smoother, save assembly time and improve assembly efficiency.

[0069] Furthermore, the flange outer shell (5) is made of lead brass plated with nickel and meets the requirements of a 96-hour neutral salt spray test.

[0070] Furthermore, the fixing plate, the front end plug-in portion and the rear end plug-in portion on the flange outer shell (5) are formed integrally.

[0071] Furthermore, a flange sealing groove (55) is provided on the flange outer shell (5), and the flange sealing groove (55) faces the front end plug-in portion (51) of the flange outer shell (5);

[0072] A sealing ring (4) is arranged in the flange sealing groove (55).

[0073] Furthermore, the flange sealing groove (55) is in a semi-dovetail shape.

[0074] Furthermore, the sealing ring is an O-ring.

[0075] The flange sealing groove (55) is designed in a half-dovetail shape, that is, the outer wall of the flange sealing groove (55) has an inclination angle of less than 90 degrees relative to the bottom. The sealing ring (4) is closely attached to the outer wall of the flange sealing groove (55), and the compression ratio of the sealing ring is limited by the size of the sealing groove and the inclination angle, which makes it easier to install while ensuring the sealing performance and is not easy to fall off.

[0076] Furthermore, the hole wall of the plug hole (53) at the front plug portion (51) protrudes from the front end surface of the external conductive adapter (3).

[0077] Furthermore, a front end of the outer guide adapter (3) is provided with a plurality of elastic clips (33) distributed along the circumferential direction, and the elastic clips (33) extend along the axial direction.

[0078] When the elastic clamping strip (33) is mainly connected to the board end connector, it is relatively clamped and fixed with the board end connector due to its elasticity.

[0079] Furthermore, the front end of the elastic clip (33) is in a curved shape.

[0080] The card strip has a curved shape.

[0081] The above are only preferred embodiments of the present invention, and do not limit the implementation mode and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
