Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted cameras, specifically to a vehicle-mounted camera. Background Technology

[0002] The existing vehicle-mounted high-definition camera rear cover 6 and PCB board 3 are connected by a mating connection between the rear cover coaxial terminal 1 (male) and the board coaxial terminal 2 (female) (see...). Figure 1 It has the following defects: 1. Since the coaxial terminal 1 of the back cover is inserted into the coaxial terminal 2 of the board end, when there is a large offset pairing, the coaxial terminal 2 of the board end may be peeled off from the PCB board, resulting in imaging failure; when there is a small offset pairing, there may be a stress of about 4N acting on the PCB board 3 for a long time, causing the PCB board 3 to be slightly deformed and creeped, thereby changing the position of the sensor 4 and the lens assembly 5 and affecting the clarity of the product.

[0003] 2. The coaxial terminal 1 on the back cover and the coaxial terminal 2 on the board are interlocked and required to be coaxial, which affects the flexibility of the arrangement and installation space of the coaxial terminal on the back cover and the arrangement space of the PCB board. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a vehicle-mounted camera that eliminates the force exerted by the coaxial terminals of the rear cover on the PCB board.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: This utility model provides a vehicle-mounted camera, including a rear cover, a PCB board, a housing, and a lens. One end of the lens is installed in the housing, and the rear cover is sealed to the housing. A coaxial terminal is installed on the rear cover. The PCB board is installed in the cavity formed by the housing and the rear cover. The PCB board and the coaxial terminal are electrically connected through a flexible connecting wire. One end of the flexible connecting wire is electrically in contact with the PCB board, and the other end is equipped with a connector. The connector is interference-fitted with the coaxial terminal.

[0006] Furthermore, the connector has a circular groove, the groove wall of which is interference-fitted with the outer circumferential surface of the coaxial terminal, and multiple spaced elastic clips extend from the bottom of the circular groove. Each elastic clip is distributed around the electrical pin at the center of the coaxial terminal, and the elastic clips cooperate with each other to clamp the electrical pin.

[0007] Furthermore, the material of the connector is the same as that of the coaxial terminal.

[0008] Furthermore, the flexible connecting wire is connected to the side of the PCB board facing away from the lens.

[0009] This utility model has the following beneficial effects: 1. The coaxial terminals of the back cover are connected to the PCB board via flexible connecting wires, eliminating the force exerted by the coaxial terminals on the PCB board and preventing the PCB board from undergoing micro-deformation and creep due to long-term stress, thereby eliminating the influence of the coaxial terminals on imaging.

[0010] 2. The placement of the coaxial terminals on the back cover is not limited by the position of the coaxial terminals on the board end, and the layout of components on the PCB is not limited by the space of the coaxial terminals on the back cover, which provides better design flexibility.

Detailed Implementation

[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0013] like Figures 2 to 4 As shown, this embodiment discloses a vehicle-mounted camera, including a rear cover 1, a PCB board 2, a housing 3, and a lens 4. One end of the lens 4 is installed in the housing 3. The rear cover 1 is sealed to the housing 3. A coaxial terminal 5 is installed on the rear cover 1. The PCB board 2 is installed in the cavity formed by the housing 3 and the rear cover 1. The PCB board 2 and the coaxial terminal 5 are connected by a flexible connecting line 6 (which is conductive). One end of the flexible connecting line 6 is electrically in contact with the PCB board 2 (by soldering or by plugging it into the PCB board 2 through a terminal), and the other end is equipped with a conductive plug 7. The plug 7 is interference-fitted with the coaxial terminal 5.

[0014] Specifically, the flexible connecting line 6 is connected to the side of the PCB board 2 facing away from the lens 4. The connector 7 has a circular groove 8, the groove wall of which is interference-fitted with the outer circumferential surface of the coaxial terminal 5. Multiple spaced elastic clips 9 extend from the bottom of the circular groove 8, and each elastic clip 9 is distributed around the contact pin 10 at the center of the coaxial terminal 5 (preferably evenly distributed). The elastic clips 9 cooperate to clamp the contact pin 10 at the center of the coaxial terminal 5. The shape of the connector 7 is not limited to this. For example, a hollow cylinder can extend from the bottom of the circular groove 8, and the end of the hollow cylinder near the contact pin 10 can be divided into multiple spaced elastic clips. Each elastic clip is distributed around the contact pin 10 at the center of the coaxial terminal 5 (preferably evenly distributed), and cooperates to clamp the contact pin 10 at the center of the coaxial terminal 5. Preferably, the material of the connector 7 is the same as the material of the coaxial terminal 5.

[0015] The gap between the coaxial terminal 5 and the rear cover 1 is sealed with glue (e.g., epoxy resin glue 11), and the gap between the lens 4 and the housing 3 is sealed with a sealing ring or with glue (e.g., epoxy resin glue). In this embodiment, the PCB board 2 is fixed to the housing 3 with screws 12. In other embodiments, the PCB board 2 can also be fixed in other ways. For example, a rib is provided on the rear cover 1, and the PCB board 2 is placed between the rib and the housing 3. The rib and the housing 3 cooperate to clamp the PCB board 2.

[0016] The vehicle-mounted camera provided in this embodiment has the following advantages: 1. The coaxial terminal 5 of the back cover 1 is connected to the PCB board 2 through a flexible connecting line 6 (such as a flexible flat cable or flexible wire), which eliminates the force exerted by the coaxial terminal 5 on the PCB board 2, prevents the PCB board 2 from undergoing micro-deformation and creep due to long-term stress, and thus eliminates the influence of the coaxial terminal 5 on imaging.

[0017] 2. The coaxial terminal 5 of the back cover 1 is connected to the PCB board 2 via a flexible connecting line 6 (such as a flexible flat cable or flexible wire). Therefore, the coaxial terminal 5 has a high degree of freedom in its arrangement position on the back cover 1, and has better design flexibility.

[0018] 3. The spatial arrangement of the flexible connecting line 6 on the PCB board 2 is not limited by the space of the coaxial terminal 5 of the back cover 1. It can be flexibly arranged according to the actual component layout requirements of the PCB board 2, giving the PCB design greater freedom.

[0019] The above description is only a preferred embodiment of the present utility model. It should be understood that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
