Description

Technical Field

[0001] This application relates to the field of connector technology, and more specifically, to an automotive Fakra connector for a camera. Background Technology

[0002] In-vehicle cameras are one of the core sensors for modern intelligent vehicles to achieve environmental perception. They are widely used in various driving assistance and autonomous driving systems. With the development of vehicle intelligence and connectivity, in-vehicle cameras, as core sensors for key functions such as advanced driver assistance systems, surround view systems, automatic parking, and driving records, are increasingly widely used. The stability of signal transmission between the camera and the vehicle electronic control unit is crucial. Fakra connectors, as the mainstream coaxial RF connectors, are widely used in the high-speed signal transmission links of in-vehicle cameras.

[0003] Due to the complex and ever-changing in-vehicle environment, vehicles encounter rain, dust, oil, and severe vibrations during operation. This places extremely high demands on the waterproof and dustproof performance and mechanical connection reliability of connectors. Although connectors have a certain level of protection, the sealing structure is prone to failure under long-term use or harsh conditions, leading to moisture intrusion, signal attenuation, short circuits, and even device damage, making it impossible to stably achieve high-level protection standards such as IP67. At the same time, for ease of maintenance or replacement, connectors need to be detachable. However, existing detachable designs are often too complex, or sacrifice ease of disassembly and assembly while ensuring connection stability, causing inconvenience for later maintenance and testing. Utility Model Content

[0004] To overcome the above shortcomings, this application provides an automotive Fakra connector for cameras, which aims to improve the problems of not being able to stably achieve high protection standards such as IP67 and the low ease of installation and removal.

[0005] This application provides an automotive Fakra connector for a camera, including a main body structure and a fixing structure. The main body structure includes a zirconia alloy outer conductor, a cover, an insulator, a center pin, and a sealing ring. The cover is located on top of the zirconia alloy outer conductor, the insulator is disposed within the inner cavity of the zirconia alloy outer conductor, the center pin is disposed within the inner cavity of the insulator, and the sealing ring is disposed on top of the insulator. The fixing structure includes a sealing gasket, a positioning component, and a disassembly / removal component. The sealing gasket is disposed on top of the inner cavity of the cover, the positioning component is located between the zirconia alloy outer conductor and the cover, and the disassembly / removal component is located within the inner cavity of the cover.

[0006] In one specific implementation, both sides of the top of the inner cavity of the cover are movably connected to a limiting frame via a damping bearing. The limiting frame is movably connected to the surface of the sealing gasket. Both sides of the top of the aluminum alloy outer conductor are provided with receiving grooves, and the lower end of the limiting frame is movably connected to the inner cavity of the receiving groove.

[0007] In the above implementation process, the limiting frame is used to limit the sealing gasket and improve the stability of the sealing gasket during use, and the receiving groove is used to accommodate the limiting frame.

[0008] In one specific implementation, the positioning component includes a mounting groove and a mounting block. The mounting groove is formed at the front and rear ends of the top of the aluminum alloy outer conductor. The mounting block is fixedly connected to the front and rear ends of the top of the cover cavity. The bottom of the mounting block extends into the cavity of the mounting groove and is detachably connected to its cavity.

[0009] In the above process, the mounting block is inserted into the inner cavity of the mounting slot, which can play a certain positioning role for the aluminum alloy outer conductor and the cover, and improve the stability of the connection between the two.

[0010] In one specific implementation, the positioning component further includes a through groove, a locking block, and a locking slot. The through groove is formed on both sides of the mounting block, the locking block is movably connected to the inner cavity of the through groove, and the locking slot is formed on both sides of the inner cavity of the mounting groove. The locking block engages with the inner cavity of the locking slot.

[0011] In the above implementation process, the through slot is used to provide space for the card block to move. When the card block is inserted into the inner cavity of the card slot, the mounting block can be fixed in the inner cavity of the mounting slot, which improves the stability of the mounting block inside the mounting slot, thereby improving the stability of the connection between the aluminum alloy outer conductor and the cover.

[0012] In one specific implementation, the positioning component further includes a fixing frame and a first spring. The fixing frame is fixedly connected to both sides of the inner cavity of the mounting block, and the first spring is fixedly connected to one side of the inner cavity of the fixing frame. The end of the first spring away from the fixing frame is fixedly connected to the locking block.

[0013] In the above implementation process, the fixing frame is used to fix the first spring, which is always in a compressed state, providing outward support force for the locking block.

[0014] In one specific implementation, the positioning component further includes a fixing rope, which is fixedly connected to one side of the two blocks that are close to each other, and the fixing rope is made of high-density woven nylon.

[0015] In the above process, the fixing rope serves to facilitate the movement of the clamp by the staff, so as to disassemble or install the aluminum alloy outer conductor and the cover.

[0016] In one specific implementation, the disassembly assembly includes a through hole and a movable rod. The through hole is opened at the front end and rear end of the inner cavity of the cover. The movable rod is slidably connected to the inner cavity of the through hole. The end of the fixing rope away from the locking block is fixedly connected to the movable rod.

[0017] In the above implementation process, the through hole is used to accommodate the movable rod and provide it with space to move. The movable rod is used to pull the fixed rope so that the workers can disassemble the mounting slot and mounting block from the outside.

[0018] In one specific implementation, the disassembly assembly further includes a fixing ring, a support ring, and a second spring. The fixing ring is fixedly connected to the inner cavity of the through hole, the support ring is fixedly connected to the surface of the movable rod, and the second spring is sleeved on the surface of the movable rod. The top and bottom of the second spring are fixedly connected to the fixing ring and the support ring, respectively.

[0019] In the above implementation process, both the fixed ring and the support ring are used to fix the second spring, which is used to provide a restoring force for the movable rod after it has moved down.

[0020] In one specific implementation, the disassembly assembly further includes a pressing plate and a protective sleeve, the pressing plate being fixedly connected to the top of the movable rod, the protective sleeve being fixedly connected to the surface of the pressing plate, and the bottom of the protective sleeve being fixedly connected to the top of the cover.

[0021] In the above process, the pressing plate facilitates the movement of the pressing rod, and the protective sleeve isolates the air, preventing moisture from entering the interior of the aluminum alloy outer conductor through the through hole.

[0022] In one specific implementation, the second spring is a stainless steel compression spring, and the protective sleeve is a TPU film.

[0023] In the above process, stainless steel springs have a long service life, and TPU films have a dense molecular structure that can effectively prevent liquid water penetration, providing an excellent waterproof barrier.

[0024] Compared with the prior art, the beneficial effects of this application are: it has a cover part, which makes it convenient for customers to automatically pick up and process the board; it has a sealing ring, which can meet the IP67 waterproof requirements; the outer conductor is made of one-piece die casting, which has good EMI performance; at the same time, under the action of the fixed structure, the aluminum alloy outer conductor and the cover can be stably installed, and it is also easy to disassemble and maintain.
