The input portion 311 has a plurality of first conductive pads 3111 for electrically connecting with the first tail portions 22 of the first conductive terminals 2. In the illustrated embodiment of the present disclosure, the input portion 311 includes two first side surfaces 3110 arranged oppositely. The first conductive pads 3111 are provided on the two first side surfaces 3110. The first conductive pads 3111 extend along the first direction A1. The first conductive pads 3111 on each side are spaced up and down along a direction parallel to the second direction A2. The first tail portions 22 can be electrically connected to the first conductive pads 3111 by abutting. Of course, in other embodiments, the first tail portions 22 may also be electrically connected to the first conductive pads 3111 by soldering.
The insertion portion 322 extends downwardly beyond the bottom wall 15 of the first insulating body 1. The insertion portion 322 has a plurality of second conductive pads 3221 for electrically connecting with the second connector 200. The insertion portion 322 includes two second side surfaces 3220 arranged oppositely. The second conductive pads 3221 are provided on the two second side surfaces 3220.

It should be noted that the position of the output portion 321 may be set at other positions than the insertion portion 322. The connection mode or connection angle of the cables 4 and the conductive components can be flexibly adjusted according to actual needs, which is not limited in the present disclosure.
In an embodiment of the present disclosure, the number of the first conductive pads 3111 is equal to the sum of the number of the second conductive pads 3221 and the number of the conductive components. Some signals (for example, non-high-speed signals) of the signals input from the input portion 311 communicate with the bottom circuit board through the electrical connection between the insertion portion 322 and the second connector 200. Some other signals (for example, high-speed signals) communicate with the cables 4 through the conductive components on the output portion 321. Compared with the prior art, by arranging the cables 4 to transmit the high-speed signals, signal integrity of the high-speed signals during transmission is improved, thereby improving the quality of data transmission. In addition, the design of the adapter circuit board 3 disclosed in the present disclosure is also beneficial to simplify the arrangement of the second conductive pads 3221 and the conductive components on the adapter circuit board 3. By arranging the second conductive pads 3221 and the conductive components at different positions on the adapter circuit board 3, the arrangement density of the second conductive pads 3221 and the conductive components is reduced, which is beneficial to realize the miniaturization of the adapter circuit board 3.

The metal shell 8 includes a first wall portion 81, a second wall portion 82 opposite to the first wall portion 81, a connecting portion 83 connecting the first wall portion 81 and the second wall portion 82, a buckling portion 84 which buckles the first wall portion 81 and the second wall portion 82 together, and a receiving cavity 80 located between the first wall portion 81 and the second wall portion 82. In an embodiment of the present disclosure, the metal shell 8 is formed by stamping, bending and buckling a metal piece. Buckling structures (for example, dovetail grooves and protrusions that cooperate with each other) are provided on the buckling portion 84. The buckling portion 84 and the connecting portion 83 are located on opposite sides of the receiving cavity 80. The height of the buckling portion 84 is lower than the height of the connecting portion 83. The first wall portion 81, the second wall portion 82, the connecting portion 83, and the buckling portion 84 enclose the outer wall of the second insulating body 6 to achieve the mutual fixation of the metal shell 8 and the second insulating body 6.
Specifically, the first wall portion 81 includes a first mounting foot 811 extending downwardly and to a side away from the second wall portion 82. The second wall portion 82 includes a second mounting foot 821 extending downwardly and to a side away from the first wall portion 81. The first mounting foot 811 and the second mounting foot 821 are adapted for being mounted on the bottom circuit board. In the illustrated embodiment of the present disclosure, in order to further improve the structural strength, the heights of the first wall portion 81, the second wall portion 82, and the connecting portion 83 are designed as high as possible. The height of the connecting portion 83 is the same as the height of the first wall portion 81 and the height of the second wall portion 82.
The metal shell 8 further includes a first tab 851 bent from the first wall portion 81 toward the second wall portion 82, and a second tab 852 bent from the second wall portion 82 toward the first wall portion 81. The metal shell 8 further includes a first extension portion 861 extending forwardly from the first wall portion 81, a first extension foot 862 extending downwardly from the first extension portion 861, and a first elastic locking arm 863 extending upwardly from the first extension portion 861. The metal shell 8 further includes a second extension portion 871 extending forwardly from the second wall portion 82 and a second extension foot 872 extending downwardly from the second extension portion 871. The first extension foot 862 and the second extension foot 872 are adapted for being mounted to the bottom circuit board.
In the illustrated embodiment of the present disclosure, the first elastic locking arm 863 has a cantilever shape, and includes a first locking hole 8631 and a first inclined portion 8632 located at a free end (i.e., a top end) of the first elastic locking arm 863. The first inclined portion 8632 extends obliquely away from the second wall portion 82. The first locking hole 8631 is adjacent to the first inclined portion 8632.
When the first connector 100 is mated with the second connector 200, the first tab 851 and the second tab 852 are inserted into the first slot 131 and the second slot 141 under the guidance of the first bell mouth 1311 and the second bell mouth 1411, respectively. The first elastic locking arm 863 changes the relative position of the first locking protrusion 132 along the first guiding surface 1322 of the first locking protrusion 132.
When the first connector 100 and the second connector 200 are mated in place, the first elastic locking arm 863 rebounds, so that the first locking protrusion 132 is locked in the first locking hole 8631. A portion of the first elastic locking arm 863 located at an upper edge of the first locking hole 8631 can be abutted against the first locking surface 1321 in a vertical direction in order to prevent the first connector 100 from being improperly separated from the second connector 200 in a direction opposite to the second direction A2. At the same time, the insertion portion 322 of the first connector 100 and a part of the first insulating body 1 are received in the second connector 200; the insertion portion 322 is inserted into the second mating slot 62 to achieve an electrical connection with the second conductive terminals 7; and a part of the first insulating body 1 is received in the receiving cavity 80.
When in use, the mating element (such as the electronic card) is inserted into the first mating slot 12 along a direction opposite to the first direction A1, which will impose an insertion force along the first direction A1 to the first connector 100. In the illustrated embodiment of the present disclosure, the first tab 851 and the second tab 852 are fixed and positioned in the first slot 131 and the second slot 141, respectively, which improves the integrity of the connector assembly and reduces the possible adverse effects of the insertion force on the connector assembly. In addition, by elevating the first wall portion 81, the second wall portion 82 and the connecting portion 83, the connecting portion 83 can better stop the first connector 100, thereby further reducing the possible adverse effect of the insertion force on the connector assembly. For example, the insertion force reduces the risk of loosening at the soldering position of the second connector 200 and the bottom circuit board, and also reduces the risk of poor contact between the conductive components of the insertion portion 322 and the second conductive terminals 7.
When unlocking is required, the first inclined portion 8632 is opened outwardly to make the first locking protrusion 132 escape from the first locking hole 8631. Then, by applying a force opposite to the second direction A2, the first connector 100 can be withdrawn from the second connector 200.

Compared with the prior art, through the interlocking locking structures of the first connector 100 and the second connector 200, the first connector 100 can be prevented from detaching from the second connector 200 in the direction opposite to the second direction A2, thereby improving the mating reliability of the first connector 100 and the second connector 200. The locking structures include an elastic locking arm and a locking protrusion which cooperate with each other, wherein the elastic locking arm is a broader concept of the first elastic locking arm 863 and the second elastic locking arm 873; the locking protrusion is a broader concept of the first locking protrusion 132 and the second locking protrusion 142. In the illustrated embodiment of the present disclosure, the locking protrusion is provided on the first connector 100, and the elastic locking arm is provided on the second connector 200. Of course, in other embodiments, the locking protrusion can also be provided on the second connector 200, and the elastic locking arm can be provided on the first connector 100, which can also achieve the function of the locking structures.
In addition, the first connector 100 and the second connector 200 further include resisting structures which are mated with each other in a direction parallel to the second direction A2. The resisting structures can play a role of limiting the position, which prevents the first connector 100 from excessively pushing the second connector 200 along the first direction A1. In some embodiments of the present disclosure, the resisting structures include a slot and a tab which cooperate with each other, wherein the slot is a broader concept of the first slot 131 and the second slot 141, and the tab is a broader concept of the first tab 851 and the second tab 852. In other embodiments of the present disclosure, the resisting structures include a stop surface and a protrusion which cooperate with each other, wherein the stop surface is a broader concept of the first stop surface 810 and the second stop surface 820, and the protrusion is a broader concept of the first protrusion 130 and the second protrusion 140.
