Description

Technical Field

[0001] The present disclosure relates to a connector assembly and a connector, and more particularly to a bus connector assembly and a bus connector. Background Art

[0002] Generally, a connector for reading an expansion card (e.g., a card-edge connector) is fixed on a circuit board (e.g., a main board). Thus, when a user inserts an expansion card into a slot on the connector, the circuit board can read the electrical signals (including receiving / transmitting current) of the expansion card. With the increasing demand for transporting large currents and simultaneously reading multiple expansion cards, it is necessary to propose a hardware architecture that can accommodate multiple connectors at the same time, ensure the structural stability between the multiple connectors, and be able to serially connect the electrical signals from different expansion cards. However, existing products have not been able to propose a connector assembly that satisfies users.

[0003] Therefore, how to propose a connector assembly and a connector that can solve the above problems is one of the problems that the industry is eager to invest in research and development resources to solve currently. Summary of the Invention

[0004] In view of this, an object of the present disclosure is to propose a connector assembly and a connector that can solve the above problems.

[0005] To achieve the above object, according to an embodiment of the present disclosure, a connector assembly includes a first circuit board, a first connector, a second circuit board, a second connector, a pin, and a stopper. The first connector is disposed on the first circuit board. The first connector includes a first conductive terminal, a first bus, and a first sleeve.

The cap portion is located at the top of the barrel body and abuts against the surface of the first bus bar. The diameter of the cap portion is larger than the diameter of the barrel body. The interference portion is disposed on the barrel body. The interference portion engages with the first bus bar. In one or more embodiments of the present disclosure, the width of the stop portion is larger than the width of the pin.

[0015] In one or more embodiments of the present disclosure, the first conductive terminal includes one or a combination of the following that are fixed to each other: a fixed conductive terminal, including a first end, a second end, a fixing portion, and a welding pin; and a floating conductive terminal, including a first end, a second end, and a fixing portion.

[0016] In one or more embodiments of the present disclosure, the first end, the second end, the fixing portion, and the welding pin of the fixed conductive terminal are on the same plane.

[0017] To achieve the above object, according to an embodiment of the present disclosure, a connector includes a first housing, a plurality of first conductive terminals, a first bus, and a first sleeve. The first housing has a first slot and a second slot spaced apart from the first slot. The first slot is for an expansion card to be inserted. Each of the first conductive terminals includes a first end corresponding to the first slot and a second end corresponding to the second slot. One end of the first bus is located in the second slot and is connected to the second end. The first sleeve is connected to the other end of the first bus and has a hollow groove or through hole.

[0019] In one or more embodiments of the present disclosure, the first conductive terminal includes one or a combination of the following fixed to each other: a fixed conductive terminal including a first end, a second end, a fixing portion, and a welding pin; and a floating conductive terminal including a first end, a second end, and a fixing portion.

[0020] In one or more embodiments of the present disclosure, the first end, the second end, the fixing portion, and the welding pin of the fixed conductive terminal are located on the same plane.

[0022] In one or more embodiments of the present disclosure, the two accommodating cavities respectively have openings for heat dissipation.

[0023] In summary, in the connector assembly and the connector disclosed herein, since the first cover and the first housing are respectively engaged with each other through the first hook and the first barb, the connection structure between the first conductive terminal, the first bus, and the first sleeve can be stabilized, thereby ensuring the stability of the overall structure of the first connector. In the connector assembly and the connector disclosed herein, since the second cover and the second housing are also respectively engaged with each other through the second hook and the second barb, the connection structure between the second conductive terminal, the second bus, and the second sleeve can be stabilized, thereby ensuring the stability of the overall structure of the second connector. In the connector assembly and the connector disclosed herein, since the pin passes through the first sleeve of the first connector and the second sleeve of the second connector at the same time, the electrical signal of the expansion card read by the second circuit board can be transmitted to the first circuit board through the pin, thereby achieving the serial connection of the electrical signals of different expansion cards from different connectors. In the connector assembly and the connector disclosed herein, since the stopper is provided in the middle section of the pin and the diameter of the stopper is greater than the diameter of the pin, the second connector is separated from the first connector by a certain distance, thereby realizing the structural stability of the first connector and the second connector in the connector assembly. In the connector assembly and the connector disclosed herein, since the crown springs are surrounded on the inner surfaces of the first sleeve and the second sleeve, in addition to increasing the contact area between the pin and the first sleeve and the second sleeve to meet the requirement of transmitting large current, the crown springs also provide a positive force between the pin and the first sleeve and the second sleeve, thereby achieving the auxiliary fixing function between the second connector and the pin. In short, the connector assembly disclosed herein can not only serially connect the electrical signals of multiple expansion cards on multiple connectors, but also achieve the structural stability of multiple connectors in the overall connector assembly.

[0024] The above is only used to elaborate on the problems to be solved by the present disclosure, the technical means for solving the problems, and the effects produced thereby. The specific details of the present disclosure will be introduced in detail in the following embodiments and related drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0084] The following will disclose multiple implementation manners of the present disclosure with the accompanying drawings. For the sake of clear illustration, many practical details will be described together in the following description. However, it should be understood that these practical details are not used to limit the present disclosure. That is to say, in some implementation manners of the present disclosure, these practical details are not necessary. In addition, for the purpose of simplifying the drawings, some well-known conventional structures and components will be shown in a simple schematic manner in the drawings. The same reference numerals will be used to represent the same or similar components in all the drawings.

[0085] The following will introduce in detail the structures, functions of the components included in the connector assembly CA of this implementation manner and the connection relationship between the components.

[0086] Please refer to Figure 1 。 Figure 1 Is a three-dimensional view of a connector assembly CA according to an implementation manner of the present disclosure. As Figure 1As shown, in this embodiment, the connector assembly CA includes a circuit board PCB1, a connector 100, a circuit board PCB2, a connector 200, pins 160A, pins 160B, a stop 170A, and a stop 170B. The connector 100 is disposed on the circuit board PCB1. The connector 200 is disposed on the circuit board PCB2. The circuit board PCB1 and the circuit board PCB2 are independently separated from each other. In some embodiments, the circuit board PCB2 is located above the circuit board PCB1 and they are parallel to each other. The connector 100 is configured for an expansion card C1 to be inserted therein, and the connector 200 is configured for an expansion card C2 to be inserted therein. The pins 160A and the pins 160B can be cylinders and are electrically connected to the connector 100 and the connector 200. With the foregoing structural configuration, when the circuit board PCB1 reads the electrical signal of the expansion card C1 and the circuit board PCB2 reads the electrical signal of the expansion card C2, the connector 200 can transmit the electrical signal of the expansion card C2 read by the circuit board PCB2 to the circuit board PCB1 through the pins 160A and the pins 160B. Thereby, the connector assembly CA can parallel the electrical signals of the expansion card C1 and the expansion card C2 and simultaneously obtain the electrical signals of the expansion card C1 and the expansion card C2 through the circuit board PCB1.

[0087] Please continue to refer to Figure 1 . As Figure 1 shown, in this embodiment, the connector 100 includes conductive terminals 110, a housing 120, buses 130A, buses 130B, a cover 140, sleeves 150A, and sleeves 150B. The housing 120 encloses a plurality of conductive terminals 110. The housing 120 has at least one slot configured for the expansion card C1 to be inserted therein. A plurality of conductive terminals 110 are disposed on the circuit board PCB1, and a part of the plurality of conductive terminals 110 is located within at least one slot to dock with the expansion card C1. The buses 130A and the buses 130B are connected to the plurality of conductive terminals 110. The cover 140 encloses the buses 130A and the buses 130B. The sleeves 150A and the sleeves 150B are respectively connected to the buses 130A and the buses 130B and have hollow grooves or through holes. As Figure 1As shown, the housing 120 includes barbs 125. The cover 140 includes a cover body 142, a snap structure, and a top plate 148. The snap structure is used to snap with the barbs 125. The snap structure includes a pressing portion 143, a connecting arm 144, and a hook 145. The pressing portion 143 is disposed on the side surface of the cover body 142. The pressing portion 143 and the hook 145 are located at two ends of the connecting arm 144. In other words, the connecting arm 144 is connected between the hook 145 and the pressing portion 143. The pressing portion 143 and the hook 145 swing relative to the cover body 142. The top plate 148 covers the cover body 142. The cover 140 may further include a separating portion 146 disposed between the cover body 142 and the top plate 148 for electrically isolating the bus 130A and the bus 130B. The separating portion 146, the cover body 142, and the top plate 148 together define two accommodating cavities for accommodating the bus 130A and the bus 130B respectively, and each accommodating cavity forms an opening OA and an opening OB on the cover 140. Specifically, the separating portion 146 divides the space formed by the cover body 142 and the top plate 148 into two accommodating cavities, and has the opening OA and the opening OB respectively for heat dissipation. As Figure 1 shown, the housing 120 and the cover 140 are snap-fitted to each other through the barbs 125 and the hooks 145 respectively. The sleeves 150A and 150B are respectively located in the two accommodating cavities of the cover 140. The sleeves 150A and 150B penetrate through the cover body 142 and the top plate 148.

[0088] Please continue to refer to Figure 1 . As Figure 1 shown, in this embodiment, the connector 200 includes conductive terminals 210, a housing 220, a bus 230A, a bus 230B, a cover 240, a sleeve 250A, and a sleeve 250B. The housing 220 houses a plurality of conductive terminals 210. The housing 220 has at least one slot configured for an expansion card C2 to be inserted. A plurality of conductive terminals 210 are disposed on a circuit board PCB2, and a part of the plurality of conductive terminals 210 is located in at least one slot to dock with the expansion card C2. The bus 230A and the bus 230B are connected to the plurality of conductive terminals 210. The cover 240 houses the bus 230A and the bus 230B. The sleeves 250A and 250B are respectively connected to the bus 230A and the bus 230B. As Figure 1As shown, the housing 220 includes barbs 225. The cover 240 includes a cover body 242, a snap structure, and a top plate 248. The snap structure is used to snap with the barbs 225. The snap structure includes a pressing portion 243, a connecting arm 244, and a hook 245. The pressing portion 243 is disposed on the side surface of the cover body 242. The pressing portion 243 and the hook 245 are located at both ends of the connecting arm 244. In other words, the connecting arm 244 is connected between the hook 245 and the pressing portion 243. The pressing portion 243 and the hook 245 swing relative to the cover body 242. The top plate 248 covers the cover body 242. The cover 240 may further include a partition portion 246 disposed between the cover body 242 and the top plate 248 for electrically isolating the bus 130A and the bus 130B. The partition portion 246, the cover body 242, and the top plate 248 together define two accommodating cavities for accommodating the bus 230A and the bus 230B respectively, and each accommodating cavity forms an opening OA and an opening OB on the cover 240. Specifically, the partition portion 246 divides the space formed by the cover body 242 and the top plate 248 into two accommodating cavities, and respectively has an opening OA and an opening OB for heat dissipation. As Figure 1 shown, the housing 220 and the cover 240 are snap-fitted to each other through the barbs 225 and the hooks 245 respectively. The sleeves 250A and 250B are respectively located in the two accommodating cavities of the cover 240. The sleeves 250A and 250B penetrate through the cover body 242. As Figure 1 shown, the top plate 248 of the cover 240 has a plurality of through holes PF for the pins 160A and 160B to pass through.

[0089] Please continue to refer to Figure 1 . As Figure 1 shown, in this embodiment, the pin 160A passes through the sleeve 150A of the connector 100 and the sleeve 250A of the connector 200. The pin 160B passes through the sleeve 150B of the connector 100 and the sleeve 250B of the connector 200. Please also refer to Figure 3, the stop portion 170A is provided on the plug 160A. The stop portion 170B is provided on the plug 160B. The stop portion 170A can be integrally formed with the plug 160A. The stop portion 170B can be integrally formed with the plug 160B. Specifically, the stop portion 170A and the stop portion 170B are respectively located in the middle sections of the plug 160A and the plug 160B. In some embodiments, the distance between the stop portion 170A and one end of the plug 160A can be shorter than the distance between the stop portion 170A and the other end of the plug 160A; the distance between the stop portion 170B and one end of the plug 160B can be shorter than the distance between the stop portion 170B and the other end of the plug 160B. In some embodiments, the diameter of the stop portion 170A is greater than the diameter of the plug 160A and also greater than the diameter of the hollow groove or through hole of the sleeve 150A and the sleeve 150B, and the diameter of the stop portion 170B is greater than the diameter of the plug 160B. In some other embodiments, the stop portion 170A and the stop portion 170B are respectively structures protruding from the outer surfaces of the plug 160A and the plug 160B, so that the widths of the stop portion 170A and the stop portion 170B are respectively greater than the widths of the plug 160A and the plug 160B, and also greater than the widths of the hollow grooves or through holes of the sleeve 150A and the sleeve 150B. This ensures that when the plug 160A passes through the sleeve 150A from top to bottom, the stop portion 170A abuts against the top of the sleeve 150A, and when the plug 160B passes through the sleeve 150B from top to bottom, the stop portion 170B abuts against the top of the sleeve 150B, so that the plug 160A and the plug 160B are stationary relative to the connector 100.

[0090] In some embodiments, the connector 100 and the connector 200 can be, for example, a card-edge connector or other similar connectors.

[0091] In some embodiments, the circuit board PCB1 is configured as the main board in the connector assembly CA, and the circuit board PCB2 can be configured as the secondary board in the connector assembly CA. In this case, the connector assembly CA can connect the electrical signals of the circuit board PCB2 as the secondary board to the circuit board PCB1 as the main board through the plug 160A and the plug 160B to simultaneously process (receive) the electrical signals of the circuit board PCB1 and the circuit board PCB2.

[0092] In some other embodiments, both the circuit board PCB1 and the circuit board PCB2 can be configured as daughter boards in the connector assembly CA. In this case, the connector assembly CA can connect the electrical signals of the circuit board PCB2 as a daughter board and the electrical signals of the circuit board PCB1 as a daughter board simultaneously through the pin 160A and the pin 160B, and then connect the electrical signals of both to the main board to process the electrical signals of the circuit board PCB1 and the circuit board PCB2 simultaneously.

[0093] In some embodiments, the bus 130A and the bus 230A are configured as positive buses, and the bus 130B and the bus 230B are configured as negative buses. Therefore, the sleeve 150A, the pin 160A, and the sleeve 250A are positively charged, while the sleeve 150B, the pin 160B, and the sleeve 250B are negatively charged.

[0094] In some embodiments, as Figure 1 shown, the two sleeves 150A and the two sleeves 150B are arranged along a direction (e.g., the direction X). The two sleeves 250A and the two sleeves 250B are arranged along a direction (e.g., the direction X). The two pins 160A and the two pins 160B are also arranged along a direction (e.g., the direction X).

[0095] In some embodiments, as Figure 1 shown, the connector assembly CA includes two pins 160A and two pins 160B. Each pin 160A and each pin 160B are configured to transmit a current of about 60 amperes or more. In other words, as Figure 1 shown, the connector assembly CA as a whole can transmit a current of about 240 amperes or more.

[0096] In some embodiments, the housing 120, the cover 140, the housing 220, and the cover 240 can be made of insulating materials. In some embodiments, the housing 120, the cover 140, the housing 220, and the cover 240 can be, for example, plastics, rubbers, or other suitable dielectric materials.

[0098] In some embodiments, the conductive terminal 110, the bus 130A, the bus 130B, the sleeve 150A, the sleeve 150B, the pin 160A, the pin 160B, the stopper 170A, the stopper 170B, the conductive terminal 210, the bus 230A, the bus 230B, the sleeve 250A and the sleeve 250B can be, for example, copper or other suitable metals or conductive materials. However, the present disclosure is not intended to limit the materials of the conductive terminal 110, the bus 130A, the bus 130B, the sleeve 150A, the sleeve 150B, the pin 160A, the pin 160B, the stopper 170A, the stopper 170B, the conductive terminal 210, the bus 230A, the bus 230B, the sleeve 250A and the sleeve 250B.

[0099] Please refer to Figure 2 . Figure 2 FIG. 1 is a perspective view of a connector assembly CA according to an embodiment of the present disclosure. For the sake of simplicity, Figure 2 Compared to Figure 1 The cover 140 and the cover 240 are omitted.

Similarly, a slot 221 is provided on one side of the housing 220, and a slot 222 is provided on the other side and is separated from the slot 221. The slot 221 is configured for the expansion card C2 to be inserted along a direction (e.g., direction Y), and the expansion card C2 contacts the conductive terminal 210.

[0100] Please continue to refer to Figure 2 .like Figure 2As shown, in the present embodiment, each of bus 130A and bus 130B includes one or more vertically extending portions 132, one or more bent portions 134, and a horizontally extending portion 136. One or more vertically extending portions 132 contact the conductive terminals 110. One or more bent portions 134 connect the one or more vertically extending portions 132. The horizontally extending portion 136 connects the one or more bent portions 134. One or more of the bent portions 134 may have a positioning structure (e.g., a groove) to facilitate positioning when the buses 130A and 130B are installed in the housing 120. Specifically, one or more vertically extending portions 132 contact the conductive terminals 110. The horizontally extending portion 136 contacts the sleeves 150A and 150B. Similarly, each of bus 230A and bus 230B includes one or more vertically extending portions 232, one or more bent portions 234, and a horizontally extending portion 236. One or more vertically extending portions 232 contact the conductive terminals 210. One or more bent portions 234 connect the one or more vertically extending portions 232.

[0101] Please refer to Figure 3 . Figure 3 is an exploded view of a connector assembly CA according to an embodiment of the present disclosure. As Figure 3 shown, in the present embodiment, the pins 160A and 160B extend along a direction (e.g., the direction Z). The portion of the pin 160A below the stop portion 170A passes through the sleeve 150A, and the portion of the pin 160A above the stop portion 170A is configured to pass through the sleeve 250A. Similarly, the portion of the pin 160B below the stop portion 170B passes through the sleeve 150B, and the portion of the pin 160B above the stop portion 170B is configured to pass through the sleeve 250B. A plurality of through holes PF may be formed on the top plate 248 to align the hollow through holes of the sleeves 250A and 250B vertically. The diameter of the through hole PF may be approximately larger than the diameter of one end of the pins 160A and 160B, so that the portions of the pins 160A and 160B passing through the sleeves 250A and 250B can also pass through the through hole PF, enabling the pins 160A and 160B to accommodate applications with different spacings between the circuit boards PCB1 and PCB2. Please continue to refer to Figure 3. In a usage scenario, first, the user can install the conductive terminal 110 and the housing 120 onto the circuit board PCB1. Then, the user installs the bus 130A, the bus 130B, the sleeve 150A, the sleeve 150B, and the cover 140 onto the housing 120, and engages the cover 140 with the housing 120. Then, the user can install the conductive terminal 210 and the housing 220 onto the circuit board PCB2. Then, the user installs the bus 230A, the bus 230B, the sleeve 250A, the sleeve 250B, and the cover 240 onto the housing 220, and engages the cover 240 with the housing 220. Then, the user installs the pin 160A onto the sleeve 150A, and also installs the pin 160B onto the sleeve 150B, and makes the stop portion 170A and the stop portion 170B respectively abut against the top of the sleeve 150A and the top of the sleeve 150B. Then, the user installs the connector 200 installed on the circuit board PCB2 onto the pin 160A and the pin 160B, and makes the pin 160A pass through the sleeve 250A, and makes the pin 160B pass through the sleeve 250B. Finally, the user fixes the circuit board PCB2 to the chassis (not shown) surrounding it, thus completing the assembly of the connector assembly CA as shown in Figures 1 to 3 . In some embodiments, the stop portion 170A and the stop portion 170B can abut against or be fixed to the connector 100. For example, the stop portion 170A and the stop portion 170B abut against the top surface or the buckle of the cover 140 and are fixed to the cover 140.

[0102] Please refer to Figure 4 . Figure 4 FIG. is a perspective view of the conductive terminal 110 according to 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 is taken as an example here for detailed description. As shown in Figure 4As shown, in the present 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 spaced apart from the first end portion 111, and a fixing structure 113 configured to fix the fixed conductive terminal 110A and the floating conductive terminal 110B. The fixing structure 113 is connected between the first end portion 111 and the second end portion 112. The first end portion 111 defines a first recess T1, and the second end portion 112 defines a second recess T2. The first end portion 111 corresponds to the slot 121, and the second end portion 112 corresponds to the slot 122. In the present embodiment, when the expansion card C1 is inserted into the slot 121 of the housing 120, the first end portion 111 of the conductive terminal 110 clamps the expansion card C1 and causes a portion of the expansion card C1 to be received in the first recess T1. When the buses 130A and 130B are inserted into the slot 122 of the housing 120, the second end portion 112 of the conductive terminal 110 clamps the vertical extension portions 132 of the buses 130A and 130B and causes a portion of the vertical extension portions 132 to be received in the second recess T2. As Figure 4 shown, the fixed conductive terminal 110A and the floating conductive terminal 110B are substantially conformal, except that the fixed conductive terminal 110A further includes a soldering pin 114 compared to the floating conductive terminal 110B, and the soldering pin 114 is connected to the fixing structure 113. The detailed structures of the fixed conductive terminal 110A and the floating conductive terminal 110B will be described below.

[0103] Please refer to Figure 5A and Figure 5B . Figure 5A A schematic diagram of the fixed conductive terminal 110A according to an embodiment of the present disclosure. Figure 5B A schematic diagram of the floating conductive terminal 110B according to an embodiment of the present disclosure. As Figure 5A and Figure 5BAs shown, in this embodiment, the fixed conductive terminal 110A includes a first end 111A, a second end 112A, a fixing portion 113A, and a soldering pin 114. The fixed conductive terminal 110A can be integrally formed, and the first end 111A, the second end 112A, the fixing portion 113A, and the soldering pin 114 are located on the same plane. The first end 111A and the second end 112A respectively define a first recess T1 and a second recess T2. The fixed conductive terminal 110A is soldered to the circuit board PCB1 through the soldering pin 114. The floating conductive terminal 110B includes a first end 111B, a second end 112B, and a fixing portion 113B. The floating conductive terminal 110B can be integrally formed, and the first end 111B, the second end 112B, and the fixing portion 113B are located on the same plane. The first end 111B and the second end 112B respectively define a first recess T1 and a second recess T2. The fixed conductive terminal 110A and the floating conductive terminal 110B are fixed to each other by riveting the fixing portion 113A and the fixing portion 113B. Through such a structural design, the contact area of the conductive terminal 110 can be increased to conduct more current. Specifically, the contact area between each conductive terminal 110 and the expansion card C1 in the contact slot 121 is widened, and the contact area between the vertical extension portion 132 in the contact slot 122 is also widened.

[0104] As Figure 4 , Figure 5A and Figure 5B shown, since only the fixed conductive terminal 110A includes the soldering 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 while the floating conductive terminal 110B does not directly contact the circuit board PCB2.

[0105] In some embodiments, the conductive terminal 110 can include a plurality of fixed conductive terminals 110A fixed to each other, or a plurality of floating conductive terminals 110B fixed to each other (i.e., the electrical signals of the expansion card do not reach the circuit board where the connector is located). In some embodiments, one of the connectors 100 and 200 can have terminals that are all two or more floating conductive terminals 110B fixed to each other, and the terminals of the other connector can include fixed conductive terminals 110A, so that the electrical signals of the two expansion cards C1 and C2 are centrally provided to one of the circuit boards PCB1 and PCB2.

[0106] Please refer to Figure 6 . Figure 6 FIG. is a top view of the cover 140 according to an embodiment of the present disclosure. For simplicity of illustration, Figure 6The top plate 148 is omitted. It should be noted that since the structures of the cover 140 and the cover 240 are similar, only the cover 140 will be taken as an example for detailed description here. As Figure 6 shown, in the present embodiment, the cover body 142 of the cover 140 further has a plurality of slots SL and a plurality of openings H. The plurality of slots SL are configured for the bus 130A and the bus 130B to pass through. The plurality of openings H are configured for the sleeves 150A and 150B to pass through. In some embodiments, the sleeves 150A and 150B are respectively fixed to the cover 140 by the frictional force between them and the inner surface of the openings H. In some embodiments, the cover body 142 further includes a plurality of positioning members BP (for example, bumps) to cooperate with the positioning structures of the bent portions 134 of the bus 130A and the bus 130B, thereby positioning the bus 130A and the bus 130B within the cover 140.

[0107] Please refer to Figure 7 . Figure 7 is a cross-sectional schematic view of the sleeve 250B, the plug 160B, and the crown spring CY according to an embodiment of the present disclosure. For simplicity of description, Figure 7 the housing 220 and the cover 240 are omitted. As Figure 7 shown, in the present embodiment, the connector assembly CA further includes a crown spring CY surrounding the inner surfaces of the hollow through-holes of the sleeve 150A, the hollow through-hole of the sleeve 150B, the hollow through-hole of the sleeve 250A, and the hollow through-hole of the sleeve 250B. It should be noted that since the component connection relationships between the sleeve 150A and the plug 160A, the sleeve 250A and the plug 160A, the sleeve 150B and the plug 160B, and the sleeve 250B and the plug 160B are similar, only the sleeve 250B and the plug 160B will be taken as an example for detailed description here. As Figure 7 shown, the crown spring CY clamps the plug 160B. The crown spring CY contacts the sleeve 250B and the plug 160B.

[0108] Please continue to refer to Figure 7 . As Figure 7 shown, in the present embodiment, the conductive terminal 210 includes a first end 211 and a second end 212 spaced apart from the first end 211. The first end 211 corresponds to the slot 221 of the housing 220 and the second end 212 corresponds to the slot 222 of the housing 220 ( Figure 7 not shown). As Figure 2 and Figure 7As shown, in the present embodiment, when the expansion card C2 is inserted into the slot 221 of the housing 220, the first end 211 of the conductive terminal 210 clamps the expansion card C2 and positions a portion of the expansion card C2 within the first recess T1. When the buses 230A and 230B are inserted into the slot 222 of the housing 220, the second end 212 of the conductive terminal 210 clamps the vertical extension 232 of the buses 230A and 230B and positions a portion of the vertical extension 232 within the second recess T2. As Figure 7 shown, the sleeve 250B includes a barrel body 252B and a cap portion 254B, and a hollow through hole therethrough extends through the barrel body 252B and the cap portion 254B. The barrel body 252B is connected to the bus 230B. The cap portion 254B is located at the top of the barrel body 252B and abuts against the surface of the bus 230B. In some embodiments, the diameter of the cap portion 254B is greater than the diameter of the barrel body 252B. As Figure 7 shown, the barrel body 252B is fixed relative to the bus 230B by the frictional force therebetween. The sleeve 250B is coupled to the horizontal extension 236 of the bus 230B. Specifically, the barrel body 252B has a rough texture, and the horizontal extension 236 has a mounting hole that is generally conforming in shape to the barrel body 252B but slightly smaller. When the sleeve 250B is inserted into the mounting hole of the horizontal extension 236, the rough texture will produce a hard interference with the surface of the mounting hole to fix the sleeve 250B to the bus 230B.

[0109] Please refer to Figure 8 . Figure 8 is an exploded view of a connector assembly CA according to an embodiment of the present disclosure. As Figure 8 shown, in the present embodiment, in addition to including the circuit board PCB1, the connector 100, the circuit board PCB2, the connector 200, the pins 160A and 160B, the connector assembly CA further includes a circuit board PCB2' and a connector 200'. The connector 200' is disposed on the circuit board PCB2'. The connector 200' includes sleeves 250A' and 250B' and has a through hole PF'. Since the structure of the connector 200' is identical to that of the connector 200, it will not be described herein again. As Figure 8 shown, the pin 160A is configured to pass through the sleeve 250A of the connector 200 and the sleeve 250A' of the connector 200', and the pin 160B is configured to pass through the sleeve 250B of the connector 200 and the sleeve 250B' of the connector 200'.

[0110] Please continue to refer to Figure 8。In a usage scenario, first, the user installs the pins 160A and 160B on the connector 100. Then, the user installs the connector 200 installed on the circuit board PCB2 onto the pins 160A and 160B, and makes the pin 160A pass through the sleeve 250A and the through hole PF of the connector 200, and makes the pin 160B pass through the sleeve 250B and the through hole PF. Then, the user installs the connector 200' installed on the circuit board PCB2' onto the pins 160A and 160B, and makes the pin 160A pass through the sleeve 250A' and the through hole PF' of the connector 200', and makes the pin 160B pass through the sleeve 250B' and the through hole PF'. Finally, the user fixes the circuit board PCB2 and the circuit board PCB2' to the housing (not shown) around them, thus completing the assembly of the connector assembly CA as shown in Figure 8 shown. As shown in Figure 8 , in this embodiment, the pins 160A and 160B can pass through two, three or more connectors along a direction (for example, the direction Z), so as to realize the connection of multiple connectors in the vertical direction.

[0111] Please refer to Figure 9 . Figure 9 is a perspective view of a connector assembly CA according to an embodiment of the present disclosure. Figure 8 The structural configuration of the connector assembly CA of Figure 9 is substantially similar to the structural configuration of the connector assembly CA of Figure 9 , the difference being that the connectors 200 and 200 of the connector assembly CA of Figure 9 are arranged along the horizontal direction (for example, the direction X). As shown in Figure 9 , in this embodiment, the connector assembly CA further includes a pin 260 in addition to the circuit board PCB2, the connector 200, the circuit board PCB2' and the connector 200'. Specifically, the pin 260 can be implemented in a shape such as an inverted U shape. In some embodiments, one end of the pin 260 passes through the through hole PF and the sleeve 250A, and the other end of the pin 260 passes through the through hole PF' and the sleeve 250A', so as to realize the connection of multiple connectors in the horizontal direction.

[0112] Please refer to Figure 10 . Figure 10 is a perspective view of a connector assembly CA according to another embodiment of the present disclosure. As shown in Figure 10As shown, in the present embodiment, the connector assembly CA includes a circuit board PCB1, a connector 300, pins 360A, pins 360B, a stop 370A, and a stop 370B. The connector 300 is disposed on the circuit board PCB1. The connector 300 is configured for an expansion card C1 to be inserted. The pins 360A and the pins 360B pass through the connector 300. The connector 300 includes conductive terminals 310, a housing 320, buses 330A, buses 330B, a cover 340, sleeves 350A, and sleeves 350B. The connector 300 is disposed on the circuit board PCB1. The housing 320 encloses a plurality of conductive terminals 310. The housing 320 is configured for an expansion card C1 to be inserted. The buses 330A and the buses 330B are connected to the plurality of conductive terminals 310. The cover 340 encloses at least a portion of the buses 330A and the buses 330B, that is, the buses 330A and the buses 330B extend a relatively long distance backward (direction Y). The sleeves 350A and the sleeves 350B are respectively connected to one end of the buses 330A and the buses 330B (including the portion exposed from the cover 340). Through such a structural design, the sizes of the sleeves 350A and the sleeves 350B are larger than the sizes of the sleeves 150A and 150B in the above embodiment, thereby improving the maximum current conduction capacity. As Figure 10 As shown, the housing 320 includes barbs 325. The cover 340 includes a cover body 342, a snap structure, and a top plate 348. The snap structure is used to snap with the barbs 325. The snap structure includes a pressing portion 343, a connecting arm 344, and a hook 345. The pressing portion 343 is disposed on the side surface of the cover body 342. The pressing portion 343 and the hook 345 are located at both ends of the connecting arm 344. In other words, the connecting arm 344 is connected between the hook 345 and the pressing portion 343. The pressing portion 343 and the hook 345 swing relative to the cover body 342. The top plate 348 covers the cover body 342. The cover 340 may further include a partition portion 346, disposed between the cover body 342 and the top plate 348, for electrically isolating the buses 330A and the buses 330B. The partition portion 346, the cover body 342, and the top plate 348 together define two accommodating cavities for respectively accommodating the buses 330A and the buses 330B, and each accommodating cavity forms an opening OA and an opening OB on the cover 340. Specifically, the partition portion 346 divides the space formed by the cover body 342 and the top plate 348 into two accommodating cavities, and respectively has the opening OA and the opening OB for heat dissipation. As Figure 1 As shown, the housing 320 and the cover 340 are respectively snapped with each other through the barbs 325 and the hooks 345. The sleeves 350A and the sleeves 350B are respectively located in the two accommodating cavities of the cover 340.

The pin 360B passes through the sleeve 350B of the connector 300. The stop portion 370A is provided on the pin 360A. The stop portion 370B is provided on the pin 360B. Specifically, the stop portion 370A and the stop portion 370B are respectively located in the middle sections of the pin 360A and the pin 360B. In some embodiments, the diameter of the stop portion 370A is greater than the diameter of the pin 360A, and the diameter of the stop portion 370B is greater than the diameter of the pin 360B. In a usage scenario, the user passes one end of the pin 360A and one end of the pin 360B through the sleeve 350A and the sleeve 350B from top to bottom, such that the sleeve 350A abuts against the stop portion 370A, and the sleeve 350B abuts against the stop portion 370B for positioning. Then, when the user desires to mount another connector on the pin 360A and the pin 360B, the two sleeves (not shown) of the aforementioned another connector respectively pass through the other ends of the pin 360A and the pin 360B, thereby connecting the pin 360A and the pin 360B between the two connectors 300.

[0114] In some embodiments, the connector 300 can be, for example, a card-edge connector or other similar connectors.

[0115] In some embodiments, the bus 330A is configured as a positive bus, and the bus 330B is configured as a negative bus. Accordingly, the sleeve 350A and the pin 360A are positively charged, while the sleeve 350B and the pin 360B are negatively charged.

The cable LA and the cable LB are respectively located in the two accommodating cavities of the cover 440. In some embodiments, the connector 400 may be, for example, a card-edge connector or other similar connectors.

[0121] In some embodiments, the bus 430A is configured as a positive bus, and the bus 430B is configured as a negative bus. Therefore, the cable LA is positively charged, and the cable LB is negatively charged.

[0122] In some embodiments, the housing 420 and the cover 440 may be made of insulating materials. In some embodiments, the housing 420 and the cover 440 may be, for example, plastic, rubber, or other suitable dielectric materials. However, the present disclosure does not intend to limit the materials of the housing 420 and the cover 440.

[0123] In some embodiments, the conductive terminals 410, the bus 430A, and the bus 430B may be made of conductive materials. In some embodiments, the conductive terminals 410, the bus 430A, and the bus 430B may be, for example, copper or other suitable metals or electrically conductive materials. However, the present disclosure does not intend to limit the materials of the conductive terminals 410, the bus 430A, and the bus 430B.

[0124] In some embodiments, as Figure 12 shown, the connector assembly CA may include a plurality of circuit boards PCB1 and a plurality of connectors 400. These circuit boards PCB1 and these connectors 400 may be arranged in the vertical direction or in the horizontal direction. For example, one of the circuit boards PCB1 is configured as the main board in the connector assembly CA, and the other circuit board PCB1 may be configured as the secondary board in the connector assembly CA. In this case, the connector assembly CA can connect the electrical signals of the other circuit board PCB1 as the secondary board to the circuit board PCB1 as the main board through the cables LA and LB of the other circuit board PCB1 to process the electrical signals of the two circuit boards PCB1 simultaneously.

[0125] In some other embodiments, both one of the circuit boards PCB1 and the other circuit board PCB1 may be configured as secondary boards in the connector assembly CA. In this case, the connector assembly CA can connect the electrical signals of the cables LA and LB of one of the circuit boards PCB1 and the electrical signals of the cables LA and LB of the other circuit board PCB1 in series, and then connect the electrical signals of the two circuit boards PCB1 to the main board simultaneously to process the electrical signals of the two circuit boards PCB1 simultaneously.

[0126] From the detailed description of the specific embodiments of the present disclosure above, it can be clearly seen that in the connector assembly and the connector of the present disclosure, since the first cover and the first housing are respectively engaged with each other through the first hook and the first barb, the connection structure between the first conductive terminal, the first bus and the first sleeve can be made stable, thereby ensuring the stability of the overall structure of the first connector. In the connector assembly and the connector of the present disclosure, since the second cover and the second housing are also respectively engaged with each other through the second hook and the second barb, the connection structure between the second conductive terminal, the second bus and the second sleeve can be made stable, thereby ensuring the stability of the overall structure of the second connector. In the connector assembly and the connector of the present disclosure, since the pin passes through the first sleeve of the first connector and the second sleeve of the second connector at the same time, the electrical signal of the expansion card read by the second circuit board can be transmitted to the first circuit board through the pin, thereby achieving the serial connection of the electrical signals of different expansion cards from different connectors. In the connector assembly and the connector of the present disclosure, since the stop portion is provided in the middle section of the pin and the diameter of the stop portion is greater than the diameter of the pin, the second connector and the first connector are separated by a certain distance, thereby realizing the structural stability of the first connector and the second connector in the connector assembly. In the connector assembly and the connector of the present disclosure, since the inner surfaces of the first sleeve and the second sleeve are surrounded by crown springs, the crown springs can not only increase the contact area between the pin and the first sleeve and the second sleeve to meet the requirement of transmitting large current, but also provide a positive force between the pin and the first sleeve and the second sleeve to achieve the auxiliary fixing function between the second connector and the pin. In summary, the connector assembly of the present disclosure can not only serially connect the electrical signals of multiple expansion cards from multiple connectors, but also achieve the structural stability of multiple connectors in the overall connector assembly.

[0127] Although the present disclosure has been disclosed as above in embodiments, it is not intended to limit the present disclosure. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure. Therefore, the protection scope of the present disclosure shall be subject to that defined by the appended claims.
