Description

Technical Field

[0001] The utility model relates to the technical field of copper parts, in particular to an anti-falling copper part. Background Art

[0002] Copper parts are commonly known as copper inlays, copper inlays, inlaid copper nuts and injection molded copper nuts. They are copper accessories inlaid in plastic. Copper inlays have good thermal conductivity. After heating, pressing the copper inlays into the plastic matrix can make the product quickly heat up and speed up work efficiency. The heated copper inlays can quickly transfer heat to the plastic parts, thereby softening the periphery of the plastic hole, and the product can be quickly pressed in. During the production of pipe joints, copper inlays are injection molded by mold injection molding. The bottom of the existing copper inlay is an open structure, and an injection molding opening is formed after the copper inlay is injected. However, in actual use, due to the long-term impact of water flow on the copper inlay and the injection molding connection part, the copper inlay and the injection molding part are easily separated and a gap is generated. Water flows through the gap to seep outward. Over time, the copper inlay will fall off directly and affect the normal use of the pipeline. Therefore, it is necessary to design a new copper inlay structure to solve the above problems. Utility Model Content
