Electric connector and assembling method thereof

Abstract

The invention discloses an electric connector and an assembling method thereof. The electric connector comprises an insulation body, a tongue plate module, first terminals, a second terminal, a third terminal and a metal shell, wherein the second terminal and the third terminal are installed between the insulation body and a tongue plate; the metal shell is assembled on the insulation body; the tongue plate module comprises the tongue plate and the first terminals; the tongue plate is assembled and fixed on the insulation body; the first terminals are integrally embedded and molded on the tongue plate; each first terminal is provided with an extending part which is embedded in the tongue plate, a second terminal containing groove is arranged on the lower surface of the tongue plate and between the first terminals; the space between the extending parts of two adjacent first terminals is greater than the width of the second terminal containing groove; the upper surface of the tongue plate is provided with a third terminal containing groove; and interference can be avoided in the assembling process of the terminals, therefore, the elastic deformation displacement space of elastic terminals is increased, simultaneously the space between the second terminal and the third terminal is increased, and the intensity of the tongue plate is strengthened. The electric connector can be manufactured and assembled easily by adopting the assembling method provided by the invention.

Description

technical field [0001] The invention relates to an electrical connector and an assembly method thereof, in particular to a composite electrical connector capable of alternate insertion of various plugs and an assembly method thereof. Background technique [0002] Known electrical connectors, such as China Taiwan Patent Application No. 97219170 (Chinese Corresponding Patent Application No. 200810173163.4; U.S. Corresponding Patent Publication No. US2009 / 0111330A1), disclose a standard USB2.0, USB3.0 and The electrical socket connector of the eSATA connector includes an insulating body, a metal shell covering the insulating body and a terminal module formed separately from the insulating body. The terminal module has an insulator assembled in the insulating body, and the front end of the insulator extends into the docking space to form a docking tongue. Wherein the upper surface of the butt tongue plate forms the first butt surface, and the lower surface forms the second butt...

AI Technical Summary

Problems solved by technology

However, this electrical connector has very limited space because three types of terminals must be arranged on the thin terminal module (tongue plate), and the three types of terminals must be staggered in the thickness direction of the tongue plate. The third type mentioned above The terminal (USB3.0 terminal) needs to be located between the first type terminal (eSATA connector terminal) and the second type terminal (USB2.0 terminal). This arrangement will greatly weaken the strength of the tongue plate, and USB2.0 The space for the elastic deformation of the terminal is limited and cannot exceed the position of the third type terminal (USB3.0 terminal) (interference will occur), so the elastic deformation ability of the terminal is affected

Moreover, there is a problem of bonding strength in the fixed structure between the separate terminal module (tongue plate) and the insulating body.

Moreover, the above-mentioned patent application does not discuss and disclose the structure and problems of manufacturability and assembleability of this connector.
