The terminal module 400 includes a mating terminal 42 that is inserted into the receiving space 20 to electrically engage with the RJ45 plug, a built-in circuit board 40 that carries and electrically connects the mating terminal 42, and a plurality of electronic components that are disposed on the built-in circuit board 40 to filter noise. The component 46 and the adapter module 44 are disposed on the built-in circuit board 40. The adapter module 44 can transmit the signal through the RJ45 plug to the docking terminal 42 and through the built-in circuit board 40 and the electronic component 46 to the circuit board 120. The mask body 600 includes a front case 620 and a rear case 640 that respectively cover the insulative housing 200 and the terminal module 400 from the front and rear directions.

Referring to the third to seventh embodiments, the built-in circuit board 40 is provided with a conductive via 401 having opposite sidewalls (not labeled). The rear housing 640 is provided with an insertion portion 647 inserted into the aforementioned conductive through hole 401, and the insertion portion 647 is press-fitted with the opposite side walls of the conductive through hole 401 to form a conductive connection ground. Since the insertion portion 647 and the opposite side walls of the conductive through hole 401 simultaneously pressurize, the stress on other portions of the rear case 640 is small, and the rear case 640 is prevented from being deformed. Of course, the conductive via 401 may be provided in any groove shape having two opposite side walls as long as it is subjected to the two forces of the insertion portion 647 in opposite directions.

The end of the insertion portion 647 is divided into two parallel extending tabs 648. The two tabs 648 are respectively press-fitted with the opposite side walls of the conductive through hole 401. The extended ends of the two tabs 648 are opposite to each other. Protrusions protruding in the direction. In the present embodiment, the extended ends of the two tabs 648 are spaced apart from each other such that the two tabs 648 have a suitable elastic force against the press fit of the two side walls. Actually, according to the force requirement, the pressing fit structure in the form of a fish eye hole can be set; the two tabs 648 can be disposed at a small distance between each other, so that the insertion portion 647 is inserted into the conductive through hole 401, and the two tabs 648 are The extending ends abut against each other to increase the pressing force; the two tabs 648 may be disposed at a large distance and have a large extension length, thereby reducing the tab 648.
