[0024] See also Figures 1 to 8 As shown, the present invention provides an electrical connector 100 , which includes an insulating body 10 , a first terminal 20 held in the insulating body 10 , a housing 30 mounted on the insulating body 10 , and a shielding component 40 covering the insulating body 10 .

[0025] The insulating body 10 is provided with a pair of longitudinally extending side walls 11, a pair of transversely extending end walls 12 and a bottom wall 13. The two ends of the side wall 11 are connected to the end wall 12, so that the side wall 11, the end wall 12 and the bottom wall 13 together form a docking cavity 14 for accommodating a docking end electrical connector 200. The bottom wall 13 is provided with a docking portion 15 protruding into the docking cavity 14. The docking portion 15 is lower than the end wall 12 and the side wall 11, and is used to accommodate the first terminal 20. The top surface 150 of the docking portion 15 is a flat surface and has two rows of terminal holes 152. The docking portion 15 extends longitudinally, and its two sides are provided with inclined guide surfaces 153 facing the side walls 11, which facilitates the opening or closing of the shielding assembly 40, and the longitudinal ends of the top surface 150 are provided with recesses 151 for cooperating with the protrusions 212 of the docking end electrical connector 200, such as Figure 4 , Figure 8 In addition, the side wall 11 and the end wall 12 form a rectangular docking frame opening 16 for the docking end electrical connector 200 to pass through and be inserted into the docking cavity 14 .

[0026] The first terminal 20 is fixed in the docking portion 15, and the top of the first terminal 20 is exposed to the top surface 150 of the docking portion 15 for electrical connection with the docking end electrical connector 200, while the bottom of the first terminal 20 protrudes downward from the docking portion 15 for installation on a circuit board (not shown).

[0027] The housing 30 includes a left housing 31 and a right housing 32 respectively covering the two side walls 11. The left housing 31 and the right housing 32 have the same structure and extend along the length direction of the side wall 11 and cover the outer wall surface of the side wall 11. At the same time, the left housing 31 and the right housing 32 are provided with a bending portion 33 at both ends in the longitudinal direction. The bending portion 33 covers the outer surface of the end wall 12 of the insulating body 10. Figure 2 As shown, the top of the bending portion 33 is provided with an inwardly folded inner flap 34, and the inwardly folded inner flap 34 has a blocking portion 35 and a limiting portion 36 extending downward from the blocking portion 35. The blocking portion 35 is U-shaped, and its opening is arranged outward to block the shielding component in the horizontal direction. The limiting portion 36 is located on the inner side of the bending portion 33 and is arranged parallel to the bending portion 33. The bottom of the bending portion 35 is supported on the bottom wall 13 of the insulating body, and the bottom end of the limiting portion 36 does not extend to the bottom wall 13 of the insulating body 10 to form a free end 360. The bending portion 33 of the left shell 31 and the bending portion 33 of the right shell 32 both cover the outer surface of the end wall 12. The top of the end wall 12 is provided with an isolation portion 17 protruding upward. The isolation portion 17 is located between the bending portion 33 of the left shell 31 and the bending portion 33 of the right shell 32, and is used to isolate the left and right shells 31, 32 and achieve a certain limiting effect.

[0028] like Figure 5 As shown, the shielding assembly 40 includes a pair of narrow shielding doors 41, spring members 42 connected to both ends of the shielding doors 41, and a stopper 43 located above the spring member 42. The shielding doors 41, spring members 42, and stopper 43 are all made of metal, wherein the two shielding doors 41 are located above the docking portion 15, and can shield the docking frame opening 16 when laid flat, to prevent external dust from entering the docking cavity 14 and causing pollution. At the same time, since it is made of metal, it has a certain function of shielding interference signals, and can be connected to the docking end electrical connector 200 before the docking end electrical connector 200 is inserted into the docking cavity 14, to achieve a grounding function. A pair of guide shafts are provided at both ends of each shielding door 41, namely a first guide shaft 44 and a second guide shaft 45, as shown in FIG. Figure 6As shown, in the closed state, the shielding door 41 is mounted on the top of the two end walls 12 of the insulating body 10 through the first guide shaft 44 and the second guide shaft 45 at both ends thereof, and the two guide shafts are arranged adjacent to each other, wherein the length of the first guide shaft 44 is greater than the second guide shaft 45, and it is connected to the top of the spring member 42, and can be used to push the spring member 42 downward. The spring member 42 is accommodated on the end wall 12 of the insulating body 10 and is located on the inner side of the limiting portion 36 of the inner flip sheet 34, and the spring member 42 is located below the U-shaped blocking portion 35, and the bottom of the spring member 42 is placed on the bottom wall 13 of the insulating body 10, so that the spring member 42 is limited in both the vertical direction and the horizontal direction, and the position will not be offset when it is extended and contracted, ensuring that the shielding door 41 can be opened and closed smoothly. It is worth mentioning that in order to better limit the spring member 42, each end wall 12 of the insulating body 10 of the present invention is provided with two guide grooves 18 for accommodating the spring member 42, and the guide grooves 18 extend perpendicularly to the bottom wall 13, and the guide grooves 18 are connected with the docking cavity 14 in the insulating body 10.

[0029] like Figures 2 to 5 As shown, during the docking process of the electrical connector 100 of the present invention and the docking end electrical connector 200, the docking end electrical connector 200 will first contact the shielding door 41 before entering the docking cavity 14. After receiving the thrust, the shielding door 41 will flip over, and one side of the shielding door 41 will sink downward into the docking cavity 14. During the whole process, the spring member 42 is compressed due to the downward pressure. After the two shielding doors 41 flip over, the docking cavity 14 is opened to accommodate the entry of the docking end electrical connector 200.

[0030] In order to prevent the spring member 42 from being separated from the shielding door 41 during the release process or causing the shielding door 41 to fall off the insulating body 10, the stopper 43 of the present invention is arranged above the end wall 12 and blocks the two guide shafts 44 and 45 to limit the guide shafts 44 and 45, thereby blocking the shielding door 41 in the vertical direction. In a preferred embodiment, the stopper 43 is in an inverted U shape, having a top arm 46 and side arms 47 extending downward from both ends of the top arm 46. The top arm 46 is located directly above the guide shafts 44 and 45, and the side arms 47 are inserted into the side wall 11 of the insulating body 10 for positioning. In addition, in order to better fix the stopper 43, the stopper 43 is arranged on the inner side of the isolation portion 17, so that the stopper 43 is restricted by the isolation portion 17 and cannot deviate outward.

[0031] In addition, the butt-end electrical connector 200 for butt-jointing with the present invention comprises an insulating base 201 and a second terminal 202 accommodated in the insulating base 201, wherein the insulating base 201 is provided with a pair of oppositely arranged side walls 203 and a tongue portion 204 located between the two side walls 203, wherein the inner surface 205 of the side wall 203 is inclined, and an "I"-shaped inner wall 206 is provided in the tongue portion 204, wherein the second terminal 202 is accommodated in the tongue portion 204, and the second terminal 202 has a first U-shaped portion 207, a second U-shaped portion 208, a third U-shaped portion 209 and a fourth U-shaped portion 210 connected in an integral manner, wherein the first U-shaped portion 207 protrudes out of the surface of the tongue portion 204, and is used for butt-jointing with the electrical connector 1 of the present invention. 00 is in docking contact with the first terminal 20, the second U-shaped portion 208 is arranged adjacent to the first U-shaped portion 207, the third U-shaped portion 209 is arranged adjacent to the second U-shaped portion 208, and the fourth U-shaped portion 210 is arranged adjacent to the third U-shaped portion 209, and the openings of the third U-shaped portion 209 and the fourth U-shaped portion 210 are in opposite directions, and the end of the fourth U-shaped portion 210 is provided with a welding foot 211 extending from the tongue portion 204. It can be seen that the first U-shaped portion 207 is located at the docking side of the second terminal 202, and the fourth U-shaped portion 210 is located at the installation side of the second terminal 202, the installation side is used to install the second terminal 202 on a circuit board (not shown), and the docking side is used to dock the second terminal 202 with the first terminal 20.
