2results about How to "Anti-electromagnetic interference" patented technology

This invention belongs to the field of communication wiring harness technology, and specifically to a novel high-strength communication wiring harness for automobiles. A rubber ring is slidably connected to the inner wall of the terminal head, and a protective component is fixedly connected to the surface of the rubber ring. The internal wiring of the terminal head is connected to a wiring harness assembly, which includes a spring wire. The protective component includes a connecting block. This invention utilizes silicone filling in the inner layer of the rubber ring to absorb vibration energy, reducing fatigue damage to the wiring harness caused by vibration. A braided mesh is used in the middle layer of the rubber ring to enhance the shielding effect against high-frequency electromagnetic fields. An outermost layer of metallized fabric further enhances the overall shielding performance. The rubber ring slides along the inner wall of the terminal head to transmit external impact forces. The connecting block compresses the connecting spring, and the spring's rebound is buffered by the friction between the rubber ring and the inner wall of the terminal head, ensuring the stability of the connection between the cable and the internal wiring of the terminal head.

This application relates to an optical receiver and an optical signal transmission device. The optical receiver includes: a circuit board, at least one optical module receiver, and a multi-channel optical input component. The optical module receiver includes a metal structural component, an optical receiving component, and a photoelectric conversion component. The metal structural component is fixed to one side of the circuit board and forms a closed space with a portion of the circuit board. The photoelectric conversion component is disposed within the closed space on the circuit board. The optical receiving component is disposed on the surface of the metal structural component facing away from the circuit board. Both the metal structural component and the circuit board are grounded. The optical input component is connected to the optical module receiver via an optical fiber. Because the embodiments of this application can form a "Faraday cage," the receiving performance of the optical module receiver can be improved. Therefore, the optical module receiver can receive long-distance, multi-channel optical signals with high speed and anti-interference capabilities. When receiving long-distance transmitted optical signals, the signal quality of the received optical signal can be significantly improved.
