Problems solved by technology
[0003] The bottom wall of the existing shielding shell must be processed by welding process to improve its stability when manufacturing the connector, resulting in an increase in manufacturing cost; in addition, the welding fixing structure on the bottom wall is directly through the butt joint Parts of the bottom walls on both sides of the seam are welded together after laser ablation. Due to the small bonding area, the bonding strength is low. For the case of a large butt joint gap, the laser welding effect will be more difficult to meet the requirements, so there is a shielding shell. After repeated plugging and unplugging of the body and the corresponding electrical connector plug, the joints are easy to crack and expand, resulting in damage to the shielding shell

Embodiment Construction
[0028] The present invention will be further elaborated below in conjunction with the accompanying drawings.
[0029] Such as Figure 1 to Figure 10 The electrical connector shown in a preferred embodiment of the present invention is a Unilink connector, which includes an insulating body 1, a plurality of conductive terminals 2 accommodated in the insulating body 1, and a terminal mounted on the insulating body 1. A shielding case 3 .
[0030] The conductive terminals 2 are formed by punching and bending conductive metal, and each conductive terminal 2 includes a pair of connecting portions 21 and a welding portion 22 .
[0031] The insulating body 1 is injection-molded on the conductive terminal 2 by using plastic materials, and it includes a base 11 and a tongue 13 protruding forward from the front end of the base 11. The upper and lower ends of the base 11 are respectively A plurality of protruding ribs 12 extending along the front-to-back direction protrude outward, and ...

The invention discloses an electric connector and a manufacturing method thereof. The electric connector comprises an insulating body, a plurality of conductive terminals and a shielding shell, wherein the plurality of conductive terminals are accommodated in the insulating body, the shielding shell is arranged on the insulating body, the shielding shell is provided with a first butt plate and a second butt plate which are butted with each other, a joining seam is formed between the first butt plate and the second butt plate, the shielding shell is provided with at least one accommodating groove at the joining seam, a filling material is filled in the accommodating groove, and the filling material can closely connect the first butt plate and the second butt plate together. By using the electric connector disclosed by the invention, the manufacturing cost of the electric connector can be reduced, and the bonding strength of the two butt plates can be improved so as to prevent the crazing and expanding of the joining seam after being inserted and pulled out many times.
Description
technical field [0001] The invention relates to an electrical connector and a manufacturing method thereof, in particular to an electrical connector capable of improving the bonding strength of a shielding shell and a manufacturing method thereof. Background technique [0002] The existing electrical connector is disclosed in Chinese patent ZL200710019590.2, which includes an insulating body, a conductive terminal accommodated in the insulating body, and a front shielding shell installed on the insulating body. The front shielding shell is composed of a planar The metal sheet is folded, including a top wall, a bottom wall, and two side walls connected with the top wall and the bottom wall. The first butt plate and the second butt plate are provided with interlocking lugs and dovetail grooves, and the butt joints of the lugs and dovetail grooves are laser welded to fix the first butt plate and the second butt plate together. [0003] The bottom wall of the existing shielding...
