Shielding piece fixing structure and connector

Abstract

The invention relates to a shielding piece fixing structure and a connector, the shielding piece fixing structure comprises a terminal, an injection molding insert and a shielding sheet, the shielding sheet is provided with a bending part used for accommodating a differential signal pair insertion end and realizing shielding between adjacent differential signal pairs, the bends are distributed at intervals by skipping one differential signal pair in the arrangement direction of the differential signal pair; the plastic wrapping the insertion end of the differential signal pair forms a terminal fixing part, and the terminal fixing part is positioned in the adaptive bend through a buckle structure so as to prevent relative displacement between the differential signal pair and the shielding sheet. According to the invention, the plastic wraps the plugging end, so that the stability of the plugging end of the signal pair is enhanced, the bending of the shielding sheet realizes the comprehensive shielding between the signal pair, the shielding effect between the signal pair is ensured, and the connection and fixation between the plastic and the bending ensure the constant distance between the plugging end terminal and the shielding sheet. And the shielding effect and the transmission of signal performance are ensured.

Description

technical field [0001] The invention belongs to the technical field of connectors, and in particular relates to a shield fixing structure and a connector. Background technique [0002] The terminals are shielded by the shielding sheet on one side. In the insertion area, the shielding between the signal terminals is often achieved by bending the shielding sheet or adding other components. However, since the insertion end of the terminal is cantilevered, As a result, when the connector is mated or in a vibration environment, the mating end of the terminal will swing, thereby causing a relative displacement between the signal terminal and the corresponding shielding sheet, thereby affecting the shielding effect and the transmission of signal performance. SUMMARY OF THE INVENTION [0003] In order to solve the above problems, the present invention provides a shielding member fixing structure, which can fix the insertion end by plastic wrapping the area outside the contact surf...

Problems solved by technology

[0002] The terminal is shielded by the shielding sheet on one side. In the mating area, the shielding between the signal terminals is usually achieved by bending the shielding sheet or adding other components. However, since the mating end of the terminal protrudes in a cantilever shape, As a result, when the connector is mated or in a vibrating environment, the mating end of the terminal will swing, so that there is a relative displacement between the signal terminal and the corresponding shielding sheet, which affects the shielding effect and the transmission of signal performance
