Electrical connector with thickness adjustment member and method of making the same

An electrical connector, comprising:

• a built-in circuit board comprising an extension portion, the extension portion comprising a first surface and a second surface opposite the first surface, the built-in circuit board comprising a plurality of mating conductive elements provided on the first surface, the extension portion having a thickness defined by a distance between the first surface and the second surface;
• an insulating member fixed to the built-in circuit board, the insulating member comprising an attachment portion, the attachment portion comprising a third surface abutting against the second surface of the built-in circuit board and a fourth surface opposite to the third surface, the attachment portion having a thickness defined by a distance between the third surface and the fourth surface;
• and
• a shielding shell defining a mating space, the extension portion and the attachment portion being at least partially located in the mating space;
• wherein the electrical connector comprises a tongue plate, the tongue plate comprises at least the extension portion and the attachment portion, and a thickness of the tongue plate comprises at least the thickness of the extension portion and the thickness of the attachment portion.

A method of manufacturing an electrical connector, the electrical connector comprising:

• a built-in circuit board comprising an extension portion, the extension portion comprising a first surface and a second surface opposite the first surface, the built-in circuit board comprising a plurality of mating conductive elements provided on the first surface, the extension portion having a thickness defined by a distance between the first surface and the second surface;
• an insulating member fixed to the built-in circuit board, the insulating member comprising an attachment portion, the attachment portion comprising a third surface abutting against the second surface of the built-in circuit board and a fourth surface opposite to the third surface, the attachment portion having a thickness defined by a distance between the third surface and the fourth surface;
• and
• a shielding shell defining a mating space, the extension portion and the attachment portion at least partially extending into the mating space;
• wherein the electrical connector comprises a tongue plate, the tongue plate comprises at least the extension portion and the attachment portion, and a thickness of the tongue plate comprises at least the thickness of the extension portion and the thickness of the attachment portion;
• the method comprising following steps:
• S1, providing the built-in circuit board, the thickness of the extension portion of the built-in circuit board being smaller than the target thickness;
• S2, providing a thickness adjustment member and injection-molding the thickness adjustment member with the built-in circuit board, the thickness of the attachment portion of the insulating member being smaller than the target thickness, at least the extension portion of the built-in circuit board and the attachment portion of the insulating member forming the tongue plate of the electrical connector, the thickness of the tongue plate comprising at least the thickness of the extension portion and the thickness of the attachment portion, and the thickness of the tongue plate reaching the target thickness;
• and
• S3, providing the shielding shell, and assembling the shielding shell with the insulating member.
