Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a triangular positioning connector. Background Art

[0002] Traditional connectors typically use circular or other non-triangular structural positioning elements for positioning during the welding process. These connectors may rely solely on pins or simple fixing structures for positioning, lacking effective guidance and stability design. This may lead to positional offset or instability during the welding process, thereby affecting welding quality and product reliability.
