Electrical connector and assembly method thereof

Abstract

The invention discloses an electric connector and an assembling method thereof. The electric connector comprises a shielding shell, a terminal module, a metal connecting shell and an insulating casing. During assembly, the terminal module is arranged in the insulating casing, the insulating casing is embedded into the metal connecting shell, the shielding shell is coated outside the terminal module and the metal connecting shell, so that the terminal module is well shielded and the grounding connection with the metal connecting shell is effectively realized; and the front end part of the metal connecting shell is exposed outside the shielding shell to form a splicing part. The electric connector has an extremely compact structure, is very convenient to assemble, and is very suitable for manufacturing micro electric connectors; and secondly, a reinforced sheet is sandwiched between a first terminal module and a second terminal module, so that the overall structural intensity of the terminal module is greatly improved, the product quality of the electric connector is improved, the service life of the electric connector is prolonged, the mold molding process is simplified, the mold molding cost is saved, and assembly is performed conveniently and rapidly.

Description

technical field [0001] The invention relates to the technology in the field of electrical connectors, in particular to an electrical connector with a compact structure and convenient assembly and an assembly method thereof. Background technique [0002] With the development trend of miniaturization and multi-functionalization of electrical equipment, the requirements for electrical connectors are increasing day by day. They not only need to have strong signal transmission capabilities, but also need to have the characteristics of miniaturization, simplification and convenience. [0003] At present, the universal serial bus interface (USB) interface has become a commonly used input / output interface, for example: including communication interface, printer interface, display output, audio output / input device and storage device, etc., one of its benefits is that it can be compared with The early RS233 interface provides faster data transmission speed, and at the same time, it re...

AI Technical Summary

Problems solved by technology

However, it is difficult for the connectors in the prior art to meet the needs of current miniature electronic products, which limits the miniaturization of electronic products; of course, there are also a small number of connectors with their compact overall structure, The advantage of small volume has become the choice of microelectronic products, but its assembly process is more troublesome, which also increases the production cost of the connector, which is not conducive to its popularization and application.
