As shown in fig. 10 to fig. 15, the five plug terminals 70 are inserted into the corresponding second terminal grooves 63 from front to back. The abutting portion 701 is exposed rearward of the rear end of the abutting portion 62 and is accommodated in the abutting space 8111. In some other embodiments, the docking body 60, the metal shell 41, the mounting bracket 82 and the five plug terminals 70 may be integrally injection-molded into a whole, so that the plug terminals 70 can be stably held, and gaps between the plug terminals 70 and the docking body 60 can be further reduced, which helps to improve the waterproof performance of the plug connector 120.
Referring to fig. 10 to 15, the second circuit board 920 is then mounted on the front end of the docking body 60 from front to back. Two sides of the rear end of the second circuit board 920 are respectively clamped in the clamping groove 66 and clamped on the upper and lower surfaces by the clamping portion 822. The metal housing 81 is electrically connected to the second circuit board 920 through the clamping portion 822 of the mounting bracket 82, so that the metal can have a shielding function to protect the plug terminal 70 from signals of other external components. The soldering portion 303 of each plug terminal 70 is soldered to the circuit board, and the rear end of the second circuit board 920 is pressed against the front end of the sleeve 702 portion of each plug terminal 70, so as to prevent each plug terminal 70 from moving forward.
Referring to fig. 10 to 12, the third magnetic element 831 and the fourth magnetic element 832 are then installed in the corresponding installation grooves 65 on the left and right sides from front to back, respectively. The stop portion 834 abuts against the front end of the mounting portion 64 to prevent the third magnetic element 831 and the fourth magnetic element 832 from moving backward. The body 833 of the third magnetic element 831 and the fourth magnetic element 832 may be fixed to the mounting groove 65 using a fixing adhesive, and the fixing adhesive may further block a gap between the body 833 and the mounting groove 65.
Referring to fig. 10 to 12, finally, the insulating housing 84 is sleeved outside the docking body 60 from front to back. The front end of the second circuit board 920 is supported against the inner wall of the insulating housing 84 and is stably fixed between the base 61 and the insulating housing 84.
Referring to fig. 14 and 15, when the plug connector 120 is normally mated with the receptacle connector 110, the front end of the cylindrical body 811 of the metal housing 81 is received in the first receiving space 4110, and the first inclined surface 4112 and the second inclined surface 812 are abutted against each other, so that a ground loop is formed between the metal housing 81 and the metal shell 41, and a shielding function is provided outside the receptacle terminal 30 and the plug terminal 70. At this time, the boss portion 22 is accommodated in the docking space 8111. The abutting portion 701 of each plug terminal 70 elastically abuts against the contact portion 301 of each receptacle terminal 30.
In the above-described first embodiment of the present invention, the five receptacle terminals 30 and the five plug terminals 70 are arranged in a row. Referring to fig. 16, in the second embodiment, five of the receptacle terminals 30 and five of the plug terminals 70 may be arranged in two rows and staggered in a W-like shape. The five receptacle terminals 30 include three upper row terminals 310 and two lower row terminals 320. The five plug terminals 70 include three upper row butting terminals 710 and two lower row butting terminals 720, which are disposed in one-to-one correspondence with the three upper row terminals 310 and the two lower row terminals 320. Taking the five plug terminals 70 of the receptacle connector 110' as an example: an anti-misplug space 350 is defined between two adjacent upper-row terminals 310 in the three upper-row terminals 310, and an anti-misplug space 350 is also defined between and on both lateral sides of the two lower-row terminals 320. When the plug connector 120 ' is reversely mated with the receptacle connector 110 ', the two lower rows of mating terminals 720 of the plug connector 120 ' respectively abut against the misplug-preventing spaces 350 between the two adjacent upper rows of terminals 310, and the three upper rows of mating terminals 710 respectively abut against the two lower rows of terminals 320 at the lateral sides and in the misplug-preventing spaces 350 therebetween, so as to prevent the five receptacle terminals 30 of the receptacle connector 110 ' and the five plug terminals 70 of the plug connector 120 ' from being mistakenly overlapped during reverse mating.
