Right-Angle PCB Connector With Integrated Shielding Structure

Solution Overview

Problem

Existing connectors for laser radar systems with right-angle configurations face structural complexity and reduced electromagnetic shielding due to the use of two separate shielding parts, complicating assembly and performance.

Innovation Solution

A single, integrally formed shield with two parts extending at a predetermined angle addresses this issue, providing improved structural simplicity and enhanced electromagnetic shielding by integrating a first and second shielding part within a housing, accommodating signal and power terminals.

AI summary

An electrical connector comprises a housing, a shield arranged within the housing and a first signal terminal. The shield includes a first shielding part extending in a first direction, and a second shielding part integrally connected to the first shielding part and extending in a second direction at a predetermined angle to the first direction. The first signal terminal is provided in the housing and is at least partially accommodated within the shield.
