[0174] Those skilled in the art will understand that, in the embodiment illustrated in the present invention, the first adapter module 201, the second adapter module 202, the support block 203, and the support housing 204 are assembled to form the adapter module 200. Then, the adapter module 200 is installed in the shielding housing 500. At this time, a first accommodating cavity 2041 is formed between the first wall portion 50a1 and the first housing portion 204a of the shielding housing 500 in the second direction A2-A2. The first accommodating cavity 2041 is located between the second wall portion 50a2 and the third wall portion 50a3 along the third direction A3-A3.

When the first electrical connector 100a is inserted forward from the rear end of the shielding housing 500 into the first receiving cavity 2041 along the first direction A1-A1, the first elastic abutment portion 351 of the first plate end terminal 35 and the second elastic abutment portion 361 of the second plate end terminal 36 of the first electrical connector 100a elastically abut against the first contact surface 201a111 of the first adapter terminal 201a1 and the second contact surface 201b111 of the second adapter terminal 201b1, respectively. The locking protrusion 8121 of the first electrical connector 100a locks into the first locking hole 50e1 to install and fix the first electrical connector 100a in the shielding housing 500.

[0175] Similarly, when the second electrical connector 100b is inserted forward from the rear end of the shielding housing 500 into the second accommodating cavity 2042 along the first direction A1-A1, the first elastic abutment portion 351 of the first plate end terminal 35 and the second elastic abutment portion 361 of the second plate end terminal 36 of the second electrical connector 100b elastically abut against the third contact surface 202a111 of the third adapter terminal 202a1 and the fourth contact surface 202b111 of the fourth adapter terminal 202b1, respectively. The locking protrusion 8121 of the second electrical connector 100b locks into the second locking hole 204c1 to install and fix the second electrical connector 100b in the shielding housing 500.

[0176] When the adapter module 200 and the shielding housing 500 are integrally mounted on the circuit board 400, the first board terminal 35 and the second board terminal 36 of the second electrical connector 100b are finally electrically connected to the circuit board 400 by means of the adapter terminal 201a1, the second adapter terminal 201b1, the third adapter terminal 202a1 and the fourth adapter terminal 202b1.

[0177] Compared to existing technologies, the electrical connector 100 of the present invention includes hybrid terminals, meaning that some terminals are connected to a cable, while others are directly or indirectly connected to the circuit board 400. For the stacked ports shown in the illustrations of the present invention (corresponding to the first receiving cavity 501a and the second receiving cavity 501b respectively), the circuit board 400 can still be installed on one side of the stacked port, rather than between them. The advantages of this arrangement are: first, it facilitates customer installation; second, the electrical connector 100 can be plugged in after the customer has installed the adapter module 200 and the shielding housing 500 together on the circuit board 400, thereby greatly reducing the inconvenience for the customer during installation and avoiding the inconvenience that the electrical connector 100 itself might cause when installing the adapter module 200 and the shielding housing 500 together on the circuit board 400.

[0178] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. The understanding of the present invention should be based on those skilled in the art. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still make modifications or equivalent substitutions to the present invention. All technical solutions and improvements that do not depart from the spirit and scope of the present invention should be covered within the scope of the claims of the present invention.
