Problems solved by technology

This connection method basically realizes the connection between the shielding sheet and the grounding contact. However, since the shielding sheet is very thin, and the solder is required not to be higher than the shielding sheet after welding, the requirements for the welding process are very strict, and the assembly pass rate is low. At the same time, the tin storage space between the bending structu

Embodiment Construction

[0024] Embodiments of contact modules of high-speed electrical connectors, such as Figure 1-5 As shown, the contact module includes a contact, an insulator 101 and a shield 102 .

[0025] The contacts are divided into ground contacts 103 and signal contacts 104. In this embodiment, the ground contacts 103 are ground pins, and the signal contacts 104 are differential pairs.

[0026] The insulator 101 is in the shape of a sheet, and the shape of its outer contour is the same as that of the prior art. In this embodiment, the insulator 101 is made by injection molding. During the manufacturing process, the signal contacts 104 and the ground contacts 103 are encapsulated in the insulator 101 at the same time. The insulator 101 is provided with an insertion hole 11, and each ground There is at least one insertion hole directly above the contact piece 103 , and the insertion hole 11 exposes the corresponding part of the ground contact piece 103 to the outside. In this embodiment, t...

Abstract

The invention relates to the field of an electric connector and especially relates to a contact module of a high-speed electric connector and a manufacture method of the module. The contact module of the high-speed electric connector comprises an insulator, grounding contacts packaged in the insulator and a shielding piece pasted on the upper side surface of the insulator. The shielding piece is provided with internally-protruding contact fingers. The contact fingers stretch downwards to the insulator. Each grounding contact is fixedly welded with the at least one contact finger of the shielding piece. In the contact module of the high-speed electric connector, since the shielding piece is provided with the contact fingers, the welding place of the grounding contact and the shielding piece is directly transferred to the insulator, larger space is provided for a connecting structure, cooperation surface between the touch fingers and the grounding contacts is enlarged, and the problem that the shielding piece of the conventional contact module for a high-speed electric connector at present is prone to be loosen is solved.

Description

technical field [0001] The invention relates to the field of electrical connectors, in particular to a contact module of a high-speed electrical connector and a manufacturing method of the module. Background technique [0002] The high-speed electrical connector is mainly composed of a housing and a contact module stacked in the housing. The contact module includes a sheet-type insulator, a contact packaged in the insulator, and a shielding sheet fixed on the upper side of the insulator. The contacts are divided into signal contacts and signal contacts. When multiple contact modules are combined and assembled in the housing, the shielding sheet is located between the sheet insulators of two adjacent contact modules, so the shielding sheet is also called Inter-chip shielding sheet. Since the grounding of the shield sheet can well suppress the mutual crosstalk between signals, the shield sheet and the ground contact of the contact module to which it belongs are electrically c...
