Fig. 1 to 8 disclose a plug connector 100 of the present invention. Referring to fig. 1 to 3, the plug connector 100 includes an insulative housing 10, a plurality of terminals 20, a metal shell 30, a circuit board 40, and a metal shell 50 enclosing the metal shell 30 and the circuit board 40 therein. The housing 10 defines a forward through mating slot 11 that defines a front mating end of the plug connector and a rear mating end. The contact 20 includes contact portions 21 and feet 22 extending from the rear end of the housing, the contact portions 21 being arranged in two rows and projecting forwardly into the mating slot 11, the feet 22 being arranged in upper and lower rows and being inclined to define a board space into which the front end of the circuit board 40 can be inserted (best seen in fig. 4). The metal shell 30 tightly covers the periphery of the insulating body 10 and has a first welding leg 31 and a second welding leg 32 located at the rear of the insulating body 10, the first and second welding legs each include a pair of welding legs located at both lateral sides of the two rows of terminal leg portions 22, and the plate space is also formed between the first and second welding legs. The circuit board 40 is located at the rear end of the insulating body 10, and the front end thereof is held in the board space. The leg portions 22 of the terminals and the first and second soldering

legs

31 and 32 of the metal shell 30 are soldered to the circuit board 40, the leg portions of the two rows of terminals are soldered to the front and back sides of the circuit board 40, respectively, and the first and second soldering legs are also soldered to the front and back sides of the circuit board, respectively. The circuit board 40 is correspondingly provided with

pads

41, 42, 43, wherein the width of the pad corresponding to the first and second soldering feet is increased.

The metal shell 40 is formed by bending a metal plate; the welding width of the first welding leg 31 is the thickness of the metal plate (i.e., the plate thickness), and the welding width of the second welding leg is larger than the thickness of the metal plate. In the embodiment, the metal shell 30 directly extends backward with a first vertical piece 311, and a side cutting surface 312 of the first vertical piece forms the first welding foot 31. The metal shell 30 directly extends backward to form a second vertical piece 321, one side of the second vertical piece is horizontally bent to form a connecting piece 322, and the metal plate surface of the connecting piece forms the second welding foot 32. In this design, the second soldering pin 32 is provided with a soldering surface by the metal plate surface of the connecting sheet 322, the metal plate surface provided by the connecting sheet is larger than the plate thickness of the metal plate, and the widened circuit board soldering pad 43 is matched to strengthen the soldering strength of the metal shell and the circuit board.

A plurality of fixing pieces 33 extend from the metal shell 30, and the fixing pieces 33 are bent perpendicularly from the rear edge of the metal shell 30 and are respectively located at the upper and lower sides of the terminal leg 22. The metal shell 50 is designed in an upper and lower two-piece manner, a recessed portion 51 is disposed at the front end of the metal shell, a buckling seam 52 is disposed in the recessed portion 51, and the fixing sheet 33 is buckled in the buckling seam 52, so that the tensile strength of the plug connector 100 can be enhanced. The metal shell 30 has abutting edges 34 fixed to each other, and the abutting edges are riveted to each other. The widening of the second welding leg 32 also improves the cracking of the butt edge 34 after multiple butt plugs.

In this embodiment, the plug connector is an HDMI connector, the metal housing 30 includes a long wall 35 and a short wall 36 opposite to each other, a pair of upper end walls 37 respectively connecting two ends of the long wall, a pair of lower end walls 38 respectively connecting two ends of the short wall, the upper and

lower end walls
