Embodiment

[0038] Such as Figure 1-7 As shown, a highly reliable and fully shielded electrical connector described in this embodiment includes a plastic base 1 and a signal module 2, the plastic base 1 is provided with a plurality of installation slots 11 arranged in the same direction, and the installation A convex hull 12 guided on one side is provided in the groove 11, and the signal module 2 is loaded into the plastic base 2 along the guiding direction of the convex hull 12, and the position between the signal module 2 and the plastic base 1 is fixed;

[0039] When the signal module 2 is loaded into the plastic base 1 along the guiding direction of the convex shell 12, the protruding special-shaped elastic arms 241 on both sides on the upper side are stuck on the rear side of the convex shell 12 after being compressed and rebounded, so that the signal module 2 is fixed on the plastic base within 1.

[0040] The signal module 2 includes a signal terminal 21, a ground terminal 22, an...

Abstract

The invention provides a high-reliability fully-shielded electric connector which comprises a plastic base and a signal module. The plastic base is provided with a plurality of mounting grooves arranged in the same direction, each mounting groove is internally provided with a single-side guiding convex hull, and the signal module is installed in the plastic base in the guiding direction of the convex hulls to fix the position between the signal module and the plastic base. The electric connector has the advantages that the shielding sheet and the grounding terminal cover the signal terminal in the whole area in the signal module, so that the antenna effect and crosstalk of the terminal at the butt joint are weakened; and the shielding sheet is fixed in a manner of combining interference crimping with laser welding, so that the connection reliability of the whole shielding sheet structure is enhanced.

Description

technical field [0001] The invention relates to the technical field of electrical connectors, in particular to a highly reliable fully shielded electrical connector. Background technique [0002] High-speed backplane connectors are widely used in 5G communications, servers, and data centers for fast transmission of large-capacity data. With the rapid development of information technology, equipment has higher and higher requirements on the transmission rate of connectors, and at the same time, the signal density is getting higher and higher. Interference between signals has become a difficult problem for the increase of connector speed and density. At present, high-speed electrical connector manufacturers use various shielding differential structures, but often the shielding effect at the signal terminal interface is insufficient, the reliability is insufficient or the process is complex, expensive, and difficult to automate. Contents of the invention [0003] The invent...
