Description

Technical Field

[0001] The utility model relates to a UMU terminal assembly. Background Art

[0002] The UMU terminal assembly is a terminal assembly wiring harness used in intelligent gas meters to replace traditional pointer-type wiring harnesses. The UMU terminal assembly is easier to install, more efficient, and is increasingly widely used. The UMU terminal assembly includes a terminal connector, multiple cables inserted into the terminal connector, an internal male connector assembly, and an external male connector assembly.
