Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and more specifically, to an adjustable-angle electrical connector. Background Technology

[0002] In existing technologies, adjustable-angle electrical connectors are widely used in applications requiring flexible connection and adjustment of electrical circuits, such as power equipment, automotive electrical systems, and industrial control systems. However, current adjustable-angle electrical connectors have many shortcomings in terms of spatial adjustment capabilities and the connection and disconnection of electrical conduits and device conduits, resulting in inconvenience during use and even affecting the stability and efficiency of the system.

[0003] First, existing electrical connectors generally have poor spatial adjustment capabilities, especially when space is limited or a wide range of angle adjustments is required. Many existing designs can only be adjusted within a certain angle range, making it difficult to meet the precise adjustment needs of complex working environments. Particularly in confined spaces, the angle adjustment of electrical connectors may be limited, preventing the achievement of the ideal connection angle. Second, the inconvenience of connecting and disconnecting electrical conduits and device conduits is also a major problem. Current electrical connectors typically use threaded, snap-fit, or plug-in structures to connect electrical conduits and device conduits. However, these connection methods often require certain operating skills and tools, especially ensuring proper alignment and tightening of components during connection and disconnection; otherwise, poor contact or loosening can easily occur.
