Description

Technical Field

[0001] The invention relates to the technical field of metal connector socket assemblies, in particular to a metal connector socket assembly. Background Art

[0002] Metal connectors have excellent advantages in the conduction of large currents, such as excellent shielding performance, good heat dissipation capacity, strong environmental resistance, and smaller installation interface size (same grade plastic products). Nowadays, most metal connector sockets on the market are in the form of pins, and the sockets and panels only rely on bolts to achieve shielding contact. Most of the existing small terminals of metal connection sockets rely on glue filling to achieve effective fixation of the small terminals. This fixation method is time-consuming and labor-intensive, and increases a lot of costs. Some products also rely on adding parts on the side to clamp the small cables to indirectly fix the small terminals. The fixing effect is limited, and the small cables in the above fixing forms are all straight-out forms, which may be crushed when the customer tightens the internal bolts. If the cable is bent 90 degrees, the bending radius is too small, and unexpected situations such as wire skin loss may occur. Summary of the invention
