Wiring Protection for Dash Cam Installation
Dashboard cameras in modern vehicles must maintain signal integrity while processing multiple high-bandwidth video streams in an electromagnetically noisy environment. Field data shows that conventional wiring solutions can experience up to 30% signal degradation due to EMI, with additional challenges from mechanical stress during vehicle operation and thermal cycling between -40°C and 85°C.
The fundamental challenge lies in maintaining reliable electrical connections and EMI shielding while accommodating manufacturing tolerances and assembly requirements in confined spaces.
This page brings together solutions from recent research—including self-adjusting spring-loaded connectors, two-stage overmolding processes, coaxial shielding architectures, and EMC-optimized housing designs. These and other approaches focus on improving reliability while reducing assembly complexity and maintaining signal quality throughout the vehicle's operational lifetime.
1. Camera Installation Box with Anti-Loosening Mechanism for Connector Retention
QINGDAO TONGRUIXIANG HEAVY IND CO LTD, QINGDAO TONGRUIXIANG HEAVY INDUSTRY CO LTD, 2023
Camera structure that prevents wire harnesses from turning loose in vehicle cameras, especially when the vehicle vibrates during operation. The structure has an installation box with an anti-loosening mechanism that prevents the sub-connector and female connector from separating. The sub-connector and female connector are inserted into the box and rotated 90 degrees horizontally by a sealing ring. This locks them in place with clamping plates to prevent turning loose. A docking mechanism with sliding connectors and locking components allows connecting the sub-connector and female connector, then locks them to prevent loosening.
2. Vehicle Camera Housing with Self-Adjusting Spring-Loaded Electrical Connectors
MAGNA ELECTRONICS INC., 2022
Vehicle camera with enhanced electrical connection to vehicle wiring through self-adjusting spring-loaded connectors that flex to maintain contact with internal circuitry as the camera housing is assembled. The camera housing has two portions, one with a lens and the other with the connector. Inside is a circuit board with an imager. As the housing parts are joined, the spring connectors engage the circuitry to electrically connect the terminals to the imager board.
3. Vehicle Camera Wiring Harness with Fan-Shaped Multi-Core Cable and Threaded Shell Connector
DONGGUAN MENSEN INTELLECTUAL MANUFACTURING SCIENCE AND TECH LIMITED CO, DONGGUAN MENSEN INTELLECTUAL MANUFACTURING SCIENCE AND TECHNOLOGY LIMITED CO, 2022
Vehicle camera wiring harness with improved connectivity and modularity for easy camera configuration. The harness uses a specialized cable design with multiple cores arranged in a fan shape. The left ends of the cores connect to terminals, covered by a shell, and the right ends go through a sheath. The shell has an external thread and nut to secure the connector. This allows adding/removing cameras by connecting/disconnecting the cores to terminals without requiring wire stripping or soldering. The blind plugs in the connectors prevent dust entry. The modular design reduces wiring complexity and failure rate compared to multiple separate camera wires.
4. Camera Housing with Self-Adjusting Coaxial Connector for Consistent Electrical Contact
MAGNA ELECTRONICS INC., 2022
Vehicle camera with self-adjusting connector for enhanced electrical connection between vehicle wiring and camera electronics. The camera housing has a connector to attach to the vehicle wiring. Inside the housing is circuitry and an image sensor. The connector has coaxial pins that self-adjust to maintain electrical contact with the internal circuitry as the housing and components may shift during assembly and use. This enables a robust connection that compensates for misalignment and tolerances.
5. Wiring Harness with Sealed Housing and Elastic Cushioning for Connector Pins
HANGZHOU HENGKANG ELECTRONICS CO LTD, 2021
A waterproof wiring harness for automotive cameras that prevents water ingress to improve reliability. The harness has a sealed housing with O-rings between the connector and housing components. The center pin of the connector threads into the housing to provide a tight seal. This prevents water from entering the connector and damaging the camera electronics. The harness also has an elastic sheet on the connector pins to cushion them during mating/unmating.
6. Wiring Harness with Mesh Tail Transition Part for Enhanced Waterproofing and Tensile Strength
HUBEI JIEYOU XINDA ELECTRONIC CO LTD, 2020
High-strength waterproof wiring harness for automotive cameras that enhances both waterproofing and tensile strength compared to conventional harnesses. The harness has a unique design with a transition piece connecting the plug base to the wire wrapping layer. This transition piece, called the mesh tail transition part, provides waterproofing and strengthens the connection between the plug and wires. The transition part has a cylindrical shape with an equal bottom and side surface area. This helps distribute forces and prevent wire breakage. The transition piece also has a screw hole parallel to the wire direction for securing the harness.
7. Vehicle-Mounted Camera Housing with Integrated Board End Connector and Unshielded Wiring Harness Alignment
HUIZHOU DESAY SV AUTOMOTIVE CO LTD, 2020
Fixing structure for vehicle-mounted camera wiring harnesses that reduces cost and improves reliability compared to existing solutions. The structure involves embedding the board end connector inside the camera housing and using a matching connector with a hole that aligns with the connector pins. This allows using unshielded connectors and wiring for the camera harness since the connector is fully enclosed in the housing. This eliminates the need for separate shielded connectors and wiring, reducing cost. It also prevents interference since the connector pins are enclosed. The embedded connector also simplifies assembly and prevents damage.
8. Wire Harness with Curved Internal Retention Structure and Protective Cover for Camera Interface
BEIJING XIAOKONG SCIENCE & TECH CO LTD, BEIJING XIAOKONG SCIENCE & TECHNOLOGY CO LTD, MEGVII INC, 2017
Wire harness for video cameras that prevents cables from disconnecting or falling off. The harness has a curved wire portion inside a cover that encloses the camera's interface. The curved wire section fixes the cable as it exits the interface through a hole in the cover. This prevents the cable from pulling out when the camera is moved or bumped. The cover also shields the interface and cables from environmental factors.
