Next, the user installs the busbar 130A, the busbar 130B, the sleeve 150A, the sleeve 150B, and the cover body 140 on the housing 120, and enables the cover body 140 to be engaged with the housing 120. Next, the user can install the conductive terminals 210 and the housing 220 on the circuit board PCB2. Next, the user installs the busbar 230A, the busbar 230B, the sleeve 250A, the sleeve 250B, and the cover body 240 on the housing 220, and enables the cover body 240 to be engaged with the housing 220.

Reference is made to FIG. 4. FIG. 4 is a perspective view of the conductive terminal 110 in accordance with an embodiment of the present disclosure. It should be noted that since the structures of the conductive terminal 110 and the conductive terminal 210 are exactly the same, only the conductive terminal 110 will be described in detail herein. As shown in FIG. 4, in this embodiment, the conductive terminal 110 includes a fixed conductive terminal 110A and a floating conductive terminal 110B. The fixed conductive terminal 110A and the floating conductive terminal 110B are fixed to each other. The conductive terminal 110 includes a first end portion 111, a second end portion 112 separated from the first end portion 111, and a fixed structure 113 configured to fix the fixed conductive terminal 110A and the floating conductive terminal 110B. The fixed structure 113 is connected between the first end portion 111 and the second end portion 112. The first end portion 111 defines a first recessed portion T1 and the second end portion 112 defines a second recessed portion T2. The first end portion 111 corresponds to the socket 121 and the second end portion 112 corresponds to the socket 122. In this embodiment, as the expansion card C1 is inserted into the socket 121 of the housing 120, the first end portion 111 of the conductive terminal 110 clamps the expansion card C1 so that the expansion card C1 is accommodated in the first recessed portion T1. As the busbar 130A and the busbar 130B are inserted into the socket 122 of the housing 120, the second end portion 112 of the conductive terminal 110 clamps the vertical extending portions 132 of the busbar 130A and the busbar 130B so that portions of the vertical extending portions 132 can be accommodated in the second recessed portion T2. As shown in FIG. 4, the fixed conductive terminal 110A and the floating conductive terminal 110B are substantially conformal. The difference in between is that the fixed conductive terminal 110A further includes a welding pin 114 compared with the floating conductive terminal 110B, and the welding pin 114 is connected to the fixed structure 113. The detailed structures of the fixed conductive terminals 110A and the floating conductive terminals 110B will be described below.
Reference is made to FIG. 5A and FIG. 5B. FIG. 5A is a schematic view of the fixed conductive terminal 110A in accordance with an embodiment of the present disclosure. FIG. 5B is a schematic view of the floating conductive terminal 110B in accordance with an embodiment of the present disclosure. As shown in FIG. 5A and FIG. 5B, in this embodiment, the fixed conductive terminal 110A includes a first end portion 111A, a second end portion 112A, a fixed portion 113A and the welding pin 114. The fixed conductive terminal 110A may be integrally formed, and the first end portion 111A, the second end portion 112A, the fixed portion 113A, and the welding pin 114 are coplanar. The first end portion 111A and the second end portion 112A respectively define the first recessed portion T1 and the second recessed portion T2. The fixed conductive terminal 110A is welded to the circuit board PCB1 by the welding pin 114. The floating conductive terminal 110B includes a first end portion 111B, a second end portion 112B, and a fixed portion 113B. The floating conductive terminal 110B may be integrally formed, and the first end portion 111B, the second end portion 112B, and the fixed portion 113B are coplanar. The first end portion 111B and the second end portion 112B respectively define the first recessed portion T1 and the second recessed portion T2. The fixed conductive terminal 110A and the floating conductive terminal 110B are fixed to each other by riveting the fixed portion 113A and the fixed portion 113B, respectively. By such structural design, a contact area of the conductive terminal 110 can be increased to conduct more current. In detail, the contact area of each of the conductive terminals 110 contacting the expansion card C1 in the socket 121 is widened, and the contact area of each of the conductive terminals 110 contacting the vertical extending portions 132 in the socket 122 is also widened.
As shown in FIG. 4, FIG. 5A, and FIG. 5B, since merely the fixed conductive terminal 110A includes the welding pin 114, when the conductive terminal 110 is disposed on the circuit board PCB1, the fixed conductive terminal 110A directly contacts the circuit board PCB1 and the floating conductive terminal 110B does not directly contact the circuit board PCB1.
In some embodiments, the conductive terminal 110 may include a plurality of fixed conductive terminals 110A fixed to each other or a plurality of floating conductive terminals 110B fixed to each other (that is, the electrical signals of the expansion card does not reach the circuit board where the connector is located). In some embodiments, the terminals of one of the connector 100 and the connector 200 may be two or more floating conductive terminals 110B fixed to each other, whereas the terminals of the other connector may be fixed conductive terminals 110A, so that the electrical signals of the expansion card C1 and the expansion card C2 are collectively provided to one of the circuit board PCB1 and the circuit board PCB2.

The sleeve 350A and the sleeve 350B are respectively connected to an end of the busbar 330A and an end of the busbar 330B (including a portion exposed to the cover body 340). By such structural design, a size of the sleeve 350A and the sleeve 350B is greater than a size of the sleeve 150A and the sleeve 150B in the aforementioned embodiment, thereby improving an ampacity (the maximum current conduction capability).

In some embodiments, the connector assembly CA as shown in FIG. 12 may include a plurality of circuit boards PCB1 and a plurality of connectors 400. These circuit boards PCB1 and these connectors 400 can be arranged in a vertical direction or a horizontal direction. For example, one of the circuit boards PCB1 can be configured as a mother board in the connector assembly CA, and the other circuit board PCB1 can be configured as a secondary board in the connector assembly CA. In this case, the connector assembly CA can receive the electrical signals of the expansion card C2 to the circuit board PCB1 as the mother board by the cable LA and the cable LB of the other circuit board PCB1, so as to process the electrical signals of the expansion card C1 and the expansion card C2 at the same time.
In some other embodiments, one of the circuit boards PCB1 and the other circuit board PCB1 can both be configured as secondary boards in the connector assembly CA. In this case, the connector assembly CA can be connected to the electrical signals of the expansion card C1 and the expansion card C2, and then transmit the electrical signals to the mother board at the same time, so as to process the electrical signals of the expansion card C1 and the expansion card C2 at the same time.
From the above detailed description of the specific embodiments of the present disclosure, it can be clearly seen that in the connector assembly and connector of the present disclosure, since the first cover body and the first housing are engaged with each other by the first hook and the first barb respectively, the connection structure among the first conductive terminal, the first busbar, and the first sleeve can be stable, thereby ensuring the stability of the overall structure of the first connector. In the connector assembly and connector of the present disclosure, since the second cover body and the second housing are also engaged with each other by the second hook and the second barb respectively, the connection structure among the second conductive terminal, the second busbar, and the second sleeve can be stable, thereby ensuring the stability of the overall structure of the second connector. In the connector assembly and connector of the present disclosure, since the plug passes through the first sleeve of the first connector and the second sleeve of the second connector at the same time, the electrical signals of the expansion card can be transmitted to the first circuit board by the plug, thereby achieving connection of electrical signals from different expansion cards with different connectors. In the connector assembly and connector of the present disclosure, since the blocking portion is disposed in the middle section of the plug, and the diameter of the blocking portion is greater than the diameter of the plug, the second connector is separated from the first connector by a distance, thereby achieving the structural ability of the first connector and the second connector in the connector assembly. In the connector assembly and connector of the present disclosure, since the inner surface of the first sleeve and the inner surface of the second sleeve are surrounded by the crown spring, the crown spring can not only increase the contact area between the plug and the first sleeve and between the plug and the second sleeve to meet the demand for transmitting large currents, the crown spring also provides a positive force between the plug and the first sleeve and between the plug and the second sleeve to achieve auxiliary fixation between the second connector and the plug. Overall, the connector assembly of the present disclosure can not only connect electrical signals from a plurality of expansion cards on a plurality of connectors, but also achieve structural stability of the plurality of connectors in the overall connector assembly.
Although the present disclosure has been described in considerable detail with reference to certain embodiments thereof, other embodiments are possible. Therefore, the spirit and scope of the appended claims should not be limited to the description of the embodiments contained herein.
It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present disclosure without departing from the scope or spirit of the disclosure. In view of the foregoing, it is intended that the present disclosure cover modifications and variations of this disclosure provided they fall within the scope of the following claims.
