[0016] See also Figures 1 to 8 As shown, the present invention discloses an electrical connector 100, which includes an insulating body 1, a plurality of terminals 2 and a metal plate 3 disposed in the insulating body 1, and an upper shell 4 and a lower shell 5 covered on the insulating body 1. The insulating body 1 includes a base 11 and two wings 12 located at the rear of both sides of the base 11. The wings 12 have an upper surface and a lower surface opposite to each other and fixing holes 121 penetrating the upper and lower surfaces. Please note that the upper and lower position relationship in this article is relative, which changes according to the shape and placement of the connector, and the front is the docking end. The metal plate 3 includes two lower plate portions 31 extending backward. The upper shell 4 includes an upper base plate 41 attached to the upper surface of the base 11 and an upper plate portion 42 located on the upper surface of the wing 12. The upper plate portion 42 has a through hole 43 corresponding to the fixing hole 121. Each lower plate portion 31 is attached to the upper surface of the corresponding wing 12 and bent to form a covering portion 32. The upper plate portion 42 covers the upper surface of the lower plate portion 31 and the two are fixed to each other. The covering portion 32 covers the lower surface of the wing 12. In this way, the upper and lower plate portions 42 and 31 are stacked on the upper surface of the wing 12 to prevent the surface of the wing 12 from being compressed and damaged by bolts and other fixings when they are fixed. The covering portion 32 of the metal plate 3 prevents the end of the metal plate 3 from warping outward and avoids the formation of a gap between the metal plate 3 and the wing 12.

[0017] Ginseng Figure 2 and Figure 7The two covering parts 32 are respectively located at the rear end of the corresponding wing part 12. The wing part 12 has inner edges adjacent to each other, and the two covering parts 32 are respectively bent outward from the inner edge of the lower plate part 31. When viewed from the back to the front, the covering part 32 is U-shaped, and the U-shaped part of the covering part 32 covers the inner edge of the wing part 12. The upper and lower plate parts 42 and 31 are fixed to each other by spot welding.

[0018] The lower housing 5 includes a lower base plate 51 attached to the lower surface of the base 11 and a magnet receiving frame 52 located at both ends of the lower base plate 51. The lower housing 5 does not extend backward to the wing 12. A magnet is placed in the magnet receiving frame 52, and recessed areas are provided on the upper and lower surfaces of the magnet. The magnet receiving frame 52 is provided with a holding arm 521 extending backward to be fixed in the recessed area.

[0019] Ginseng Figure 4 and Figure 6 One of the two wings 12 is a rectangular structure extending in the front-to-back direction, and the other wing 12 is a rectangular structure extending in the left-right direction. Each wing 12 is provided with a notch 122 for accommodating the covering portion 32. A connecting portion 13 is connected between the wing 12 and the base 11. An upper connecting plate 44 is provided between the upper plate portion 42 of the upper shell 4 and the upper base plate 41, and the upper connecting plate 44 covers the connecting portion 13. The lower shell 5 includes a lower connecting plate 53 covering the connecting portion 13, and the upper and lower connecting plates 44, 53 are fixed to each other at the lateral ends of the connecting portion 13. The upper connecting plate 44 is provided with a protruding buckling piece 441, and the lower connecting plate 53 is provided with a buckling hole 531, and the protruding buckling piece 441 is buckled in the buckling hole 531.

[0020] The upper shell 4 is provided with a fixing protrusion 45 between the upper base plate 41 and the upper connecting plate 44. The fixing protrusion 45 is bent downward and fixed in the base 11. Figure 8 The fixing lug 45 inserted into the base 11 is located behind the upper base plate 41 and between the base 11 and the magnet receiving frame 52. The fixing lug 45 is blocked by the magnet receiving frame 52 of the lower shell 5. The protruding retaining piece 441 and the retaining hole 531 are both located behind the magnet receiving frame 52.

[0021] The base 11 is provided with a docking cavity 14 extending forwardly. The docking cavity 14 extends in the transverse direction. The docking cavity 14 is located at the upper shell 4 and protrudes forwardly from the lower shell 5. The front end of the metal plate 3 extends into the docking cavity 14.
