Description

Technical Field

[0001] The utility model belongs to the technical field of differential electric connectors, in particular to an insulator housing of a female end of a connector. Background Art

[0002] Differential signaling is a signaling method that transmits information through two wires. It uses two symmetrical signal lines (usually marked as V+ and V-) to transmit information. Compared with single-ended signals, differential signals can significantly improve the ability to resist electromagnetic interference (EMI). In differential signals, when the voltage of V+ is higher than that of V-, the receiving end will recognize it as a logic 1 (positive signal); when the voltage of V+ is lower than that of V-, the receiving end will recognize it as a logic 0 (negative signal). This method extracts the signal by comparing the voltage difference between V+ and V-, thereby effectively offsetting the impact of electromagnetic noise in the environment on the signal. Although the use of differential signaling schemes will increase the complexity of the interface circuit, its excellent anti-interference ability, strong signal integrity and suppression of environmental noise make differential signals widely used in high-speed data transmission and long-distance communication. For example, standards such as USB, HDMI, and Ethernet all use differential signaling technology.

The insulating material housing is provided with outer wall segments corresponding to the wire insertion space inside the housing, which can at least partially extend into the gap formed by each associated operating member after the operating member is switched to a closed state, and the outer wall segments form movable spaces on both sides thereof for the operating member to perform opening and closing operations.
