Type-c connector

Abstract

An insulating shell of the type-c connector is formed by combining an upper insulating block and a lower insulating block, a butt joint part at the front end and a plate connecting part at the rear end are obtained, an upper row of terminals and the upper insulating block are integrated in an injection molding mode, a lower row of terminals and the lower insulating block are integrated in an injection molding mode, and a shielding piece is embedded between the upper insulating block and the lower insulating block. The first iron shell wraps the butt joint part of the insulating shell, and the second iron shell wraps the connecting plate part of the insulating shell and is in conducting connection with the first iron shell; and the circuit board is hidden in the second iron shell and is in welded connection with the upper row of terminals, the lower row of terminals and the shielding sheet. The terminals and the shell are formed through one-time injection molding, high-frequency characteristic impedance, insertion loss, return loss, crosstalk and the like are facilitated, the connector is divided into two same half combinations, the manufacturing cost is greatly reduced, and manufacturing and assembling are convenient. The iron shell and the EMI sheet are integrated together, so that the manufacturing and assembling of the middle EMI sheet are reduced; the number of parts is small, tolerance accumulation caused by assembly is reduced, and the assembly stability and the use performance of the electric connector are improved.

Description

technical field [0001] The present invention relates to the technical field of electrical connectors, in particular to a data transmission type type-c connector. Background technique [0002] With the development of science and technology, all kinds of electronic products emerge in an endless stream, and a variety of corresponding connectors for different electronic products emerge as the times require. The USB connector is one of the most widely used and popular electrical connectors. Electronic devices are equipped with USB connectors. At present, the USB TYPE-C connector can only transmit power in one direction due to its double-sided pluggable interface. Unlike the old USB port, the power transmission of the TYPE-C port is bidirectional. , notebooks and other mobile devices, can be used for charging, data transmission and other purposes. [0003] The new-generation USB TYPE-C connector is smaller in size and has higher requirements for mechanical properties and electri...

AI Technical Summary

Problems solved by technology

[0003] The new generation of USB TYPE-C connectors are smaller in size and have higher requirements for mechanical properties and electrical properties, such as higher transmission rates; however, due to the small size of the new generation of USB TYPE-C connectors and the large number of terminals, Due to the limited space, in order to meet the functional requirements, the new generation of USB TYPE-C connectors is not only complex in structure, but also relatively cumbersome in production and high in investment costs.
