Various views of the inventive electrical connector 100 are shown in the first to fifth figures.

The present electrical connector 100 includes an insulative housing 1, a metal housing 3, and a plurality of terminal sets 2.

The insulative housing 1 includes a base body 11 and a tongue plate 12 extending forward from the base body 11. The insulative housing 11 is further provided with a terminal receiving groove 10 extending through the base body 11 and the tongue plate 12. The base body 11 of the insulative housing 1 is provided with a retaining groove 111 extending in the vertical direction. A holding groove 112 is defined in the middle of the bottom of the insulating body 1. The end portion of the holding groove 112 is provided with an anti-back hole 113 and a step portion 114 is formed.

The terminal set 2 includes a set of active terminals 21 and a set of passive terminals 22. The active terminal 21 is provided with a tilt-up elastic arm 211 which is folded back downward at an appropriate position and forms the contact 212 at the highest position. The passive terminal 22 includes a flat contact portion 221, and a probe 222 that penetrates the inside of the tongue plate 12 is slightly provided at the front end of the passive terminal 22. Both the active terminal 21 and the passive terminal 22 include soldering portions 213 and 223, and the lower ends of the two sets of soldering portions 213 and 223 are flush.

The terminal group 2 is assembled in the terminal receiving groove 10 provided in the insulating body 1, and the active terminal 21 and the passive terminal 22 are respectively disposed on the upper and lower sides of the tongue plate 12. A rear end of the insulative housing 1 is provided with a plurality of positioning slots 101 extending upward and downward. The positioning slot 101 fixes the active terminal 21 and the passive terminal 22 one by one.

The metal casing 3 is a square cylindrical body which is formed by folding a metal plate. The metal casing 3 includes a top plate 31 and a side wall 32 vertically formed by two ends of the top plate 31. The two ends of the metal plate are riveted to form a bottom plate 33, and the outer plate 33 is punched out at an appropriate position to form four vertical walls 32. Solder tab 34. The two ends of the bottom plate 33 are riveted to each other and then extend out of the latching arm 331. The lateral side of the latching arm 331 extends with a horizontal hook 332 which is in the shape of an arrow and is provided with a guiding inclined surface. The two card arms 331 have an angle therebetween, and the opening faces backward. There is a gradient difference between the bottom plate 33 and the card arm 331, so that the two card arms 331 form a lever in the gradient changing direction to facilitate the clamping of the card arm 331. A buckle arm 321 extending in the up-and-down direction is formed on the rear portion of the side wall 32, and the buckle arm 321 is fastened in the fastening groove 111.

The assembly of the present electrical connector 100 is described below. The active terminal 21 and the passive terminal 22 are assembled in the terminal receiving slot 10 of the insulative housing 1. The probe 222 of the passive terminal 22 is probed into the tongue plate 12. At this time, the positioning slot 101 is positioned. The active terminal 21 and the passive terminal 22 are separated by a certain gap to facilitate the soldering of the terminal group 2. The lower ends of the welded portions 213 and 223 of the active terminal 21 and the passive terminal 22 are flush to ensure the coplanarity of the terminal group 2. The metal casing 3 covers the insulative housing 1 after assembling the terminal group 2.
