[0002] With the development of automotive electronic and electrical technology, market users have increasingly urgent requirements for commercial vehicle reliability, safety, comfort and intelligence. It has become an inevitable trend to match the whole vehicle with an imaging system to improve driving safety. At present, light commercial vehicles are mostly equipped with analog high-definition imaging systems. The video transmission line from the cab display terminal to the camera at the rear of the cargo box is divided into four sections at most. The shielding performance of the segment connection point and the reliability of the connector directly affect the effective transmission of the video signal.

[0003] At present, most light commercial vehicles' analog video cables are connected at breakpoints on the front firewall using connectors. This connection method destroys the shielding effect of the original analog video cables. When connectors are used for docking, the terminals are exposed, which can easily introduce interference signals into the video cables, affecting the effective transmission of analog signals. At the same time, when connectors are used for docking, vibrations may occur at the terminal matching position, causing momentary interruptions and affecting the continuous transmission of analog video signals.

The arc-shaped stopper 13 and the limiting plate 22 are used to abut against the end face of the plug of the video cable 100.

[0040] Without destroying the shielding effect of the original video cable 100, the video cable 100 is effectively fixed, the reliability of video signal transmission is improved, and the connection is changed from a non-sealed state to a sealed state, reaching the IP67 level, effectively preventing corrosion at the connection, and solving the problem of exposed terminals caused by connector docking, which easily introduces interference signals into the video cable 100 and affects the effective transmission of analog signals. It also avoids the risk of momentary faults caused by vibration of the terminal matching position caused by connector docking, which affects the continuous transmission of analog video signals.

[0041] To cope with the expansion and deformation of the threading cavity 12, a reserved groove 122 is optionally provided on the side wall of the threading cavity 12. The threading cavity 12 is cylindrical, and the reserved groove 122 is provided on the side wall along the axial direction of the threading cavity 12. Two reserved grooves 122 may be provided to facilitate the elastic deformation of the side wall of the threading cavity 12 between the two reserved grooves 122 under the extrusion of the video cable 100, thereby achieving the fastening of the video cable 100.

[0042] To adapt to the expansion and deformation of the threading cavity 12, optionally, an avoidance groove 211 is provided on the support rib 21. In addition, three support ribs 21 can be provided to form multi-point support for the outer wall of the threading cavity 12. For easy assembly, a first guide slope 212 is provided on the support rib 21.

[0043] Optionally, a sink 14 is provided on the bracket body 1, and an elastic clamping arm 15 is provided in the sink 14. The elastic clamping arm 15 is used to clamp with the firewall partition. The elastic clamping arm 15 is provided with a clamping tongue 151, and the clamping tongue 151 can extend into the firewall partition. The design of the sink 14 and the elastic clamping arm 15 can adapt to firewall partitions of various thicknesses. Four sinks 14 and four elastic clamping arms 15 can be provided, and two of them are distributed on two opposite side walls of the bracket body 1 to form a multi-point limit.

[0044] To prevent the bracket body 1 from moving, a limiting boss 16 is optionally provided on the bracket body 1, and the limiting boss 16 is used to abut against the firewall partition. To reduce the weight of the entire bracket body 1, a weight reduction groove 17 is optionally provided on the bracket body 1. The bracket body 1 can be integrally formed by injection molding, and the material can be PP material. To avoid stress concentration during injection molding, a molding cavity 18 is optionally provided on the bracket body 1.

[0045] To facilitate the assembly of the locking member 2 and the bracket body 1, optionally, a through slot 111 is provided at the bottom of the slide slot 11, and a limiting rib 23 that slides with the through slot 111 is provided on the locking member 2. To prevent the locking member 2 from being separated from the bracket body 1, optionally, a locking rib 112 is provided in the through slot 111, and a locking slot 231 that can cooperate with the locking rib 112 is provided on the limiting rib 23.

[0046] For easy assembly, optionally, a limiting protrusion 232 is provided on the limiting rib 23, and the limiting protrusion 232 can be in contact with the locking rib 112.
