Description

Technical Field

[0001] The present application relates to the technical field of automobile accessories, and more specifically, to a camera harness assembly, a vehicle-mounted camera and a vehicle. Background Art

[0002] As the acquisition element of the automobile imaging system and intelligent driving monitoring device, the vehicle camera must not only have excellent waterproof and dustproof capabilities, but also reliable anti-static capabilities in view of its use environment and other factors, so as to meet the normal working conditions in various harsh environments. If the camera cannot quickly discharge static electricity after being interfered with by static electricity, error frames will appear in the signal transmission; when the video deserialization chip has no frame loss and error frame processing functions, obvious jamming and information loss will occur, which will have an adverse effect on the normal transmission of the camera signal, resulting in signal loss, and screen flickering, screen flower and other phenomena, thus affecting the driving safety of intelligent driving.

[0003] Generally speaking, vehicle-mounted cameras, especially in the application of intelligent driving solutions based on vision solutions, have high power consumption, so metal casings must be used for continuous heat dissipation.

[0004] The existing anti-static solution for metal shell cameras generally adds an insulating coating on the surface of the camera, or adds an anti-static silicone ring structure on the camera; however, both the insulating coating and the anti-static silicone ring will affect the heat dissipation of the camera and cannot truly eliminate the influence of static electricity; in addition, in the existing vehicle structure, the camera installation environment is mostly a plastic body, and it is impossible to directly discharge static electricity through the connection between the metal shell of the camera and the body.

[0005] In view of this, a new technical solution needs to be proposed to improve the electrostatic anti-interference ability of the vehicle-mounted camera. Utility Model Content

[0039] In the camera harness assembly 1 provided in the embodiment of the present application, the coaxial harness 12 is plugged into the plug interface 110 of the plug connector 11, which not only plays a role in signal transmission, but also the far end of the coaxial harness 12 away from the plug connector 11 is grounded, which plays a role in static discharge. Furthermore, a ground wire 13 is provided in the camera harness assembly 1 provided in the embodiment of the present application, one end of the ground wire 13 is in contact with the plug connector 11, and the other end of the ground wire 13 is overlapped with the body of the vehicle to which the camera harness assembly is applied, so as to realize rapid static discharge, thereby effectively improving the anti-static interference capability of the vehicle-mounted camera, and solving the problem of abnormal images when the vehicle-mounted camera receives signals in a complex electromagnetic environment.

[0040] In one embodiment, the length of the grounding wire 13 is less than or equal to 2 meters.

[0041] In this specific example, the length of the grounding wire 13 does not exceed 2 meters, thereby ensuring an effective electrostatic discharge effect; since the grounding wire 13 itself has resistance, when the length of the grounding wire 13 is greater than 2 meters, the static discharge effect will deteriorate.

[0042] Reference Figure 1 , Figure 3 As shown, in one embodiment, the connector 11 includes an outer sheath 111 and a conductive shell 112 , one end of the conductive shell 112 is connected to the outer sheath 111 , and the plug port 110 is opened at the other end of the conductive shell 112 .

[0045] In this specific example, one end of the ground wire 13 is in contact with the outer wall of the conductive housing 112 in the connector 11 .

[0046] Reference Figure 1 , Figure 3 As shown, in one embodiment, the coaxial harness 12 includes an inner core 121 and a shielding layer 120, the shielding layer 120 is wrapped around the outside of the inner core 121, and a portion of the inner core 121 is exposed from the shielding layer 120; the inner core 121 exposed from the shielding layer 120 is plugged into the plug port 110.

A portion of the inner core 121 is exposed from the shielding layer 120 and plugged into the plug port 110 to achieve signal transmission.

[0048] Reference Figure 1 , Figure 3 As shown, in one embodiment, the shielding layer 120 wraps around and is connected to the outer wall of the conductive shell 112 .

[0049] In this specific example, the shielding layer 120 wraps around and is connected to the outer wall of the conductive shell 112 , thereby further enhancing the electromagnetic shielding effect.

[0050] Reference Figure 1 to Figure 4 As shown, in one embodiment, the camera harness assembly further includes a sleeve 14, a portion of the sleeve 14 is sleeved on the outside of the conductive housing 112, and another portion of the sleeve 14 is sleeved on the outside of the coaxial harness 12;

[0051] One end of the grounding wire 13 is located between the conductive housing 112 and the sleeve 14 .

[0052] In this specific example, in order to provide better protection, support and stable connection, the camera harness assembly also includes a sleeve 14; a portion of the sleeve 14 is sleeved on the outside of the conductive housing 112, and another portion is sleeved on the outside of the coaxial harness 12, and one end of the ground wire 13 is located between the conductive housing 112 and the sleeve 14; the sleeve 14 can provide effective protection for the ground wire 13, and can firmly and reliably fix the connector 11, the coaxial harness 12 and the ground wire 13. Optionally, the material of the sleeve 14 can be copper, for example.

[0053] In addition, the ground wire 13 and the conductive shell 112 can be connected by means of clamping, welding, etc.; and the sleeve 14 is used for crimping, so that the assembly operation is simple and easy to implement, and the cost is low.

[0055] In this specific example, the side wall of the sleeve 14 is a corrugated structure extending in the axial direction; specifically, the sleeve 14 includes a convex portion 141 with a larger diameter and a concave portion 142 with a smaller diameter, and the convex portion 141 and the concave portion 142 are staggered in the axial direction. Such a structure enables the sleeve 14 to provide a greater crimping force, so that the sleeve 14 can more effectively press the conductive housing 112, the grounding wire 13 and the coaxial harness 12.
