AI Technical Summary
In environments with vibration, traditional connectors are prone to separation between the male and female connectors due to vibrations in the X, Y, and Z directions. Furthermore, they require high mating precision and cannot tolerate errors.
The design of the floating signal connector employs a first floating structure and a second floating structure, allowing the male and female terminals to float in the insertion direction (Z direction) and perpendicular to the insertion direction (X and Y directions). The floating of the terminals is achieved by providing elasticity through conductive springs and a planar structure, allowing for a certain degree of mating deviation.
It achieves reliable connection in vibration environments, allows male and female connectors to float in the X, Y, and Z directions, adapts to a wider range of application scenarios, and maintains the stability of electrical connection without being limited by the number of pins.
