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 structure and the shielding sheet is very small, and the bonding between the shielding sheet and the grounding contact is not firm after welding, so when the vertical shielding sheet is forced upward or is used in a vibration and shock environment, the shielding sheet will It is easy to fall off from the insulator, and once the above problems occur, it will directly lead to the grounding failure of the shielding sheet. Naturally, the grounding failure of the shielding sheet of any contact module will directly reduce the transmission performance of the high-speed electrical connector

Embodiment Construction
[0019] Examples of high-speed electrical connectors, such as Figure 1-5 As shown, the contact module includes a housing and a contact module. The structure of the housing and its assembly method with the contact module are all in the prior art, and will not be repeated here. The contact module includes contacts, insulators 101 and shielding sheets 102 .
[0020] 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.
[0021] 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 in...

The invention relates to the field of electric connector and especially to a high-speed electric connector. The high-speed electric connector comprises a housing and a contact element module. The contact element module comprises an insulator, grounding contact elements packaged in the insulator, and a shielding sheet pasted on the top side surface of the insulator. The shielding sheet is provided with contact fingers protruded inwardly. The contact fingers are downwardly inserted into the insulator. Each grounding contact element is soldered and fixed on at least one contact finger of the shielding sheet. In the high-speed electric connector, the contact fingers are disposed on the shielding sheet such that the soldering positions of the grounding contact elements and the shielding sheet are directly transferred to the insulator. Thus, larger space can be obviously provided for a connection structure in order to enlarge cooperative surfaces between the contact fingers and the grounding contact elements. Therefore, a problem is solved that the shielding sheet of the contact element module of a conventional high-speed electric connector is liable to loosen.
Description
technical field [0001] The invention relates to the field of electrical connectors, in particular to a high-speed electrical connector. Background technique [0002] The high-speed electrical connector is mainly composed of a housing and a contact module stacked up and down 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. , where 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 For inter-chip shielding film. 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 connected. Of course, the reason why hi...
