Description

Technical Field

[0001] The present invention relates to a connector and its terminal group, and particularly to a power connector and its terminal group. Background Art

[0002] For common power connectors applied in servers, in order to enable the power connector to transfer a larger current, relevant manufacturers will increase the cross-sectional area of the conductive spring arms in the power connector. As the cross-section of the conductive spring arms increases, the overall thickness of the conductive spring arms also increases accordingly.

[0044] In the following description, if a specific drawing is pointed out or as shown in a specific drawing, it is only used to emphasize that in the subsequent description, most of the relevant content mentioned appears in that specific drawing, but it does not limit that only that specific drawing can be referred to in the subsequent description.

[0045] Please refer to together Figures 1 to 3 , Figure 1 And Figure 2Schematic diagrams of different perspectives of the power connector of the present invention, respectively, Figure 3 are partial cross-sectional and exploded schematic diagrams of the power connector of the present invention. The power connector 100 of the present invention includes an insulating base 1 and two terminal groups 2. One side of the insulating base 1 has two support arms 11, the two support arms 11 are arranged at intervals from each other, and a slot 12 is formed between the two support arms 11. The insulating base 1 has two accommodation spaces 13, and the two terminal groups 2 are fixedly arranged in the two accommodation spaces 13 of the insulating base 1 in an electrically isolated manner. The insulating base 1 has a partition 14 between the two accommodation spaces 13 to electrically isolate the two terminal groups 2.

[0046] The power connector 100 mainly serves as a connection bridge between an electrical device and a power supply, and the power connector 100 can be used to transfer a large current (for example: 500 - 1000 amperes) provided by the power supply to the electrical device. The electrical device can be, for example, a server, etc. The two terminal groups 2 are respectively connected to two cable groups, and the two terminal groups 2 can be respectively connected to different potential terminals of the power supply.

[0047] Please refer to Figure 1 、 Figures 3 to 6 , Figure 4 is an exploded schematic diagram of one of the terminal groups of the power connector of the present invention, Figure 5 is a partial exploded schematic diagram of one of the terminal groups of the power connector of the present invention, Figure 6 is a schematic diagram of the elastic conductive structure of the power connector of the present invention.

[0048] Each terminal group 2 includes at least one conductive shaft column 21, at least one conductive member 22 and at least one elastic conductive structure 23. In this embodiment, each terminal group 2 includes a conductive shaft column 21, a conductive member 22 and three elastic conductive structures 23. Regarding the number of the conductive shaft column 21, the conductive member 22 and the elastic conductive structure 23 included in each terminal group 2, they can all be changed according to actual needs, and are not limited to those shown in the figure.

[0049] The conductive shaft column 21 is fixedly arranged in the insulating base 1. The conductive shaft column 21 can be a cylindrical structure (such as a cylindrical copper rod). The two ends of the conductive shaft column 21 can be directly fixed to the insulating base 1 or indirectly fixed to the insulating base 1 (the position relative to the insulating base 1 is fixed) by means of clamping, bonding, welding, etc. One end of the conductive member 22 is electrically connected to the conductive shaft column 21, and the other end of the conductive member 22 has a plurality of elastic arms. Three elastic conductive structures 23 are arranged between the conductive member 22 and the conductive shaft column 21, so that the conductive shaft column 21 and the conductive member 22 can perform relative movement, that is, when the relative rotation or the surface of the conductive shaft column 21 moves relative to the surface of the conductive member 22 or their combined movement occurs, the conductive member 22 and the conductive shaft column 21 can maintain an electrical connection relationship with each other through the elastic conductive structure 23.

[0050] As Figure 5 and Figure 6 shown, each elastic conductive structure 23 can be a conductive sheet body, which can be bent into a structure similar to a cylinder or other suitable appearance. There is at least one elastic structure on the elastic conductive structure 23. The conductive sheet body includes a main body 231 and at least one elastic structure. The elastic structure is an elastic arm 232. One root 2322 at one end of the elastic arm 232 is connected to the sheet main body 231, and the other end of each elastic arm 232 can be a free end or connected to the sheet main body 231. In a preferred application, the free end 2321 of each elastic arm 232 is arranged adjacent to the root 2322 of another adjacent elastic arm 232, that is, except for the elastic arms 232 on the outermost sides, the roots 2322 of two other elastic arms 232 are on both sides of the free end 2321 of each elastic arm 232.

[0051] When the elastic conductive structure 23 is arranged between the conductive shaft column 21 and the conductive part 22, each elastic arm 232 is compressed and elastically deformed. With such a design, the contact area and the forward force between the elastic conductive structure 23, the conductive part 22 and the conductive shaft column 21 can be enhanced, so that the conductive part 22 and the conductive shaft column 21 have good large-current conduction ability with each other.

[0052] As Figure 5 shown, in one specific application, one end of each conductive part 22 can be bent into three bent fixing parts 221. A hollow groove 222 is formed inside each bent fixing part 221. The hollow grooves 222 are arranged in a row to form a channel, and the channel is used to accommodate the conductive shaft column 21 and three elastic conductive structures 23. The number of the bent fixing parts 221 corresponds to the number of the elastic conductive structures 23, that is, one or more elastic conductive structures 23 can be accommodated in the hollow groove 222. The overall shape of the hollow groove 222 can be generally cylindrical. After the conductive part 22 is connected to the conductive shaft column 21 through the elastic conductive structure 23, when the other end of the conductive part 22 is pushed by an external force, the whole conductive part 22 can rotate relative to the conductive shaft column 21.

[0053] The other end of each conductive part 22 is arranged on the support arm 11, and a part of it is exposed outside the support arm 11. The parts of the two conductive parts 22 of the two terminal groups 2 exposed outside the support arm 11 are arranged facing each other. In actual application, the other end of each conductive part 22 can also include a plurality of connecting arms 223, and there is a gap between each connecting arm 223.

[0054] In practical applications, each terminal group 2 may further include an elastic member 24. One end of the elastic member 24 is fixed to one of the terminal groups 2 or the insulating base 1. For example, one end of the elastic member 24 may be snap-fitted into a groove 211 of the conductive shaft 21, or one end of the elastic member 24 may also be snap-fitted with a related structure (such as a groove, not shown in the figure) in the insulating base 1. The other end of each elastic member 24 is located inside the support arm 11 and outside the plurality of elastic arms of the conductive member 22. When the conductive member 22 rotates or moves relative to the conductive shaft 21 and elastically deforms, the elastic member 24 can provide a force for the conductive member 22 to act in the other direction (i.e., toward the slot 12). The material of the elastic member 24 can be made of an elastic material such as stainless steel.

[0055] The thickness of each elastic member 24 is less than the thickness of each conductive member 22. For example, the thickness of each conductive member 22 is 1.5 mm or more, while the thickness of the elastic member 24 can be less than 1 mm (such as 0.8 mm). In addition, the thickness of the conductive member 22 is basically adjusted according to the current carried by the power connector 100. For example, when the power connector 100 carries a current of 500 - 1000 amperes, the thickness of each conductive member 22 can be 3.0 mm or more.

[0056] In an example where the power connector 100 is not provided with the elastic member 24, the position of the rotated conductive member 22 can be restricted through the structural design of the inner side of the support arm 11. Thus, it is ensured that after the conductive member 22 rotates, it can still firmly hold a power supply member A1 of a power supply mechanism A.

[0057] In practical applications, each terminal group 2 further includes a plurality of conductive connection pieces 25. Each of the conductive connection pieces 25 is disposed in the insulating base 1 at intervals. Each conductive connection piece 25 is electrically connected to the conductive shaft 21; in practical applications, it can also be fixedly connected so that the conductive shaft 21 cannot rotate. Each conductive connection piece 25 can be plate-shaped, and at least part of it is disposed in the gap between two adjacent bent fixing portions 221, and each conductive connection piece 25 is perpendicular to the long axis direction of the conductive shaft 21. The insulating base 1 can have a plurality of engaging grooves 15 in each accommodating space 13. Each engaging groove 15 is disposed on two opposite sides of the accommodating space 13 facing each other. The two ends of each conductive connection piece 25 are snap-fitted into two relatively arranged engaging grooves 15. In practice, each conductive connection piece 25 and the two engaging grooves 15 can be fixed to each other in a tight fit manner. After a plurality of conductive connection pieces 25 are fixedly disposed in two accommodating spaces 13, a plurality of wire grooves 16 will be separated (as Figure 2As shown. Each wire groove 16 is used to accommodate one or more cables connected to the conductive connection piece 25. The two terminal groups 2 can be respectively connected to two cable groups, each cable group includes at least one cable, and the two terminal groups 2 and the two cable groups respectively conduct current transmission at different potentials.

[0058] It is worth mentioning that in practical applications, the maximum current that can be transmitted by the cables connected to each terminal group 2 can be changed by increasing or decreasing the number of conductive connection pieces 25 and cables included in each terminal group 2. In other words, the number of conductive connection pieces 25 included in each terminal group 2 can be adjusted according to the actual current transmission requirements to adjust the applicable current range of the power connector 100 to achieve a modular function.

[0059] For example, when each terminal group 2 only includes a single conductive connection piece 25, the power connector 100 can transmit a current of, for example, 250 amperes; when each terminal group 2 includes 2, 3, or 4 conductive connection pieces 25, and at the same time the thickness of the conductive member 22 is correspondingly increased, the power connector 100 can be used to transmit currents of 500 amperes, 750 amperes, and 1000 amperes respectively.

[0060] Please also refer to Figures 4 to 8 , Figure 7 is a schematic cross-sectional view along the Figure 1 section line VII-VII, Figure 8 is a schematic cross-sectional view of the mutual insertion of the power connector of the present invention and the power supply mechanism. After the two terminal groups 2 are arranged on the insulating base 1, the parts of the two conductive members 22 exposed from the support arm 11 are located in the slot 12, and a plugging gap is formed between the two conductive members 22 located in the slot 12. When the power supply member A1 is not inserted into the slot 12, the plugging gap is smaller than the thickness of the power supply member A1 of the power supply mechanism A.

[0061] As Figure 7 and Figure 8 shown, when the power connector 100 is inserted into the power supply mechanism A and the power supply member A1 is correspondingly inserted into the slot 12, the power supply member A1 will abut against a part of the two conductive members 22 exposed from the slot 12, so that each conductive member 22 rotates relative to the insulating base 1 through the conductive shaft column 21. The elastic member 24 on one side of each conductive member 22 will be elastically deformed outward under the pushing of the conductive member 22, and at the same time will provide a positive force for the conductive member 22 to clamp the power supply member A1. Thus, the two conductive members 22 will be affected by the elastic restoring forces of the two elastic members 24 and firmly clamp the power supply member A1.

[0062] In other words, the main source of the forward force for the two conductive members 22 of the power connector 100 of the present invention to clamp the power supply member A1 comes from the elastic restoring force generated by the compression of the two elastic members 24. The elastic restoring force generated by the compression of the two conductive members 22 themselves is less than the elastic restoring force of the two elastic members 24. Through the above design, since the conductive members 22 are not the main source of the acting force for clamping the power supply member A1, the thickness of the conductive members 22 can increase as the current carried by the power connector 100 increases. And since the conductive members 22 can rotate relative to the insulating base, therefore, when the thickness of the conductive members 22 increases, the forward force applied by the two conductive members 22 to the clamped power supply member A1 will not increase significantly. In this way, while ensuring that the power connector 100 can transmit large currents (such as 500 amperes to 1000 amperes, or even more than 1000 amperes), it can also provide an appropriate clamping force to clamp the power supply member of the power supply.

[0063] Please refer to Figures 7 to 10 , Figure 9 which is a partial cross-sectional and exploded view of the insulating base and the auxiliary conductive member of the power connector of the present invention, Figure 10 and is a schematic diagram of the auxiliary conductive member of the power connector of the present invention. In practical applications, the power connector 100 may further include a plurality of auxiliary conductive members 26, which are disposed in the two accommodating spaces 13 of the insulating base 1.

[0064] Each auxiliary conductive member 26 is electrically connected to one of the conductive members 22 and at least one of the conductive connection pieces 25 to increase the maximum current-carrying capacity from the conductive member 22 to the conductive connection piece 25. Each auxiliary conductive member 26, for example, includes a plate body 261, a plurality of fixing parts 262, and an arc-shaped sheet structure 263. Both sides of the plate body 261 extend in the same direction to form a plurality of fixing parts 262, and the whole of the plate body 261 and the plurality of fixing parts 262 may have an approximately U-shaped outer profile. The insulating base 1 has a convex part 17 between each engaging groove 15. The plate body 261 of each auxiliary conductive member 26 is located on the top surface of the convex part 17, and the plurality of fixing parts 262 are correspondingly located in the engaging grooves 15. The outer side of each fixing part 262 may include a plurality of bump structures 2621, and the plurality of bump structures 2621 are used to strengthen the connection between the fixing part 262 and the conductive connection piece 25. A part of the auxiliary conductive member 26 is jointly clamped by the insulating base 1 and the conductive connection piece 25. In practical applications, the power connector 100B may further include a engaging member 29, and the engaging member 29 is used for being engaged and arranged in the insulating base 1. The engaging member 29 may include two arm parts 291 and a connecting part 292. The two ends of the connecting part 292 are connected to the two arm parts 291, and the whole engaging member 29 may be generally in a C shape. The insulating base 1 may have two engaging grooves 19. When the engaging member 29 is fixed in the insulating base 1, the two arm parts 291 are correspondingly engaged and arranged in the engaging grooves 19. Each arm part 291 may further include a first auxiliary engaging structure 2911, and the plate body 261 of each auxiliary conductive member 26 may correspondingly have a second auxiliary engaging structure 2611, and the first auxiliary engaging structure 2911 can be engaged with the second auxiliary engaging structure 2611. For example, the first auxiliary engaging structure 2911 and the second auxiliary engaging structure 2611 may be a convex block and a perforation respectively.

[0065] One end of each auxiliary conductive member 26 has an arc-shaped sheet structure 263, and a plurality of elastic structures 2631 are arranged on the arc-shaped sheet structure 263, and the plurality of elastic structures 2631 are used for abutting against the bent fixing part 221 of the conductive member 22. One end of each elastic structure 2631 may be a free end 26311, and the free end 26311 is arranged adjacent to the root 26312 of another adjacent elastic structure 2631.

[0066] Such as Figure 3 , Figure 7 And Figure 9As shown, after the two terminal groups 2 are disposed in the two accommodating spaces 13, each arcuate sheet structure 263 will correspondingly abut against the outer surface of the bending fixing portion 221 of the adjacent conductive member 22, and each elastic structure 2631 will be compressed to generate an elastic restoring force. By electrically connecting the inner surface and the outer surface of the bending fixing portion 221 through the elastic conductive structure 23 and the auxiliary conductive member 26 respectively, the electrical connection path between the conductive member 22 and the conductive connecting piece 25 can be increased, and the overall impedance value of the terminal group 2 and the heat generated when conducting a large current can be reduced. In the scenario where the power connector 100 bears a high current (such as above 500 amperes), by adding the auxiliary conductive member 26, the problem of overheating of the conductive member 22 can be avoided.

[0067] Please also refer to Figures 11 to 16 , Figure 11 which is a partial cross-sectional schematic view of the second embodiment of the power connector of the present invention, Figure 12 being a partial cross-sectional schematic view, Figure 13 being Figure 12 a side view of Figure 14 which is an exploded schematic view of the terminal group of the second embodiment of the power connector of the present invention, Figure 15 and Figure 16 being respectively Figure 14 two partial enlarged schematic views of

[0068] The power connector 100 of the present invention includes an insulating base 1 and two terminal groups 2, and the two terminal groups 2 are disposed in the insulating base 1. Each terminal group 2 includes a first conductive member 22A, a second conductive member 22B, and two elastic members 24.

[0069] The difference between the insulating base 1 of this embodiment and the foregoing embodiment is that: the insulating base 1 includes an insulating body 1A and an insulating cover 1B. In the accommodating space 13 within the insulating body 1A, there is also an auxiliary fixing structure 18, and the insulating body 1A defines a fixing groove 18A through the fixing structure 18. One side of the insulating body 1A is an open side, and the first conductive member 22A and the second conductive member 22B can be inserted into the fixing groove 18A of the insulating body 1A through the open side. The insulating cover 1B correspondingly has a sheet-like structure 1B1. When the insulating body 1A and the insulating cover 1B are fixed to each other, the sheet-like structure 1B1 correspondingly shields the open side of the insulating body 1A, so that the sides of the first conductive member 22A and the second conductive member 22B are not exposed. The insulating cover 1B also has two support arms 11. After the two terminal groups 2 are disposed in the insulating base 1, the portions of the first conductive member 22A and the second conductive member 22B that are exposed from the support arms 11 are located in the slots 12 of the two support arms 11, and there is an insertion gap formed between the two terminal groups 2 located in the slots 12.

[0070] The assembly method of the power connector in this embodiment can be as follows: First, insert each terminal group 2 into each accommodating space 13. At this time, a part of each first conductive member 22A and each second conductive member 22B is snap-fitted and fixed in the fixing groove 18A of the accommodating space 13 through the auxiliary fixing structure 18, and the two terminal groups 2 are electrically isolated and positioned by the partition plate 14. Then, after fixedly combining the insulating cover body 1B and the insulating body 1A, the assembly of the power connector 100 can be completed. In practical applications, the fixing groove 18A defined by the auxiliary fixing structure 18 can include a first accommodating space 181 and a second accommodating space 182. A part of the first conductive member 22A and a part of the second conductive member 22B are respectively arranged in the first accommodating space 181 and the second accommodating space 182. At least a part of the sections of the first accommodating space 181 and the second accommodating space 182 can be curved.

[0071] As Figure 14 shown, it shows an exploded view of a single terminal group 2. One end of the first conductive member 22A has a first contact arm 22A1, and the other end of the first conductive member 22A has a plurality of conductive connection pieces 25. The first contact arm 22A1 and the plurality of conductive connection pieces 25 can be connected by a plurality of flexible conductive sheets 27. In one example, a part of the sections at one end of the plurality of flexible conductive sheets 27 can be fixed to each other to form the first contact arm 22A1; in another example, the first contact arm 22A1 and the plurality of flexible conductive sheets 27 can be separate components, and a part of the sections at one end of the plurality of flexible conductive sheets 27 is fixed to the first contact arm 22A1. Among them, the sections of the plurality of flexible conductive sheets 27 included in the first conductive member 22A between the first contact arm 22A1 and the plurality of conductive connection pieces 25 are not fixed to each other to form a flexible part, and the flexible part can be deformed, and the first contact arm 22A1 and the plurality of conductive connection pieces 25 can be displaced relative to each other through the flexible part.

[0072] One end of the second conductive member 22B has a plurality of second contact arms 22B1, and the other end of the second conductive member 22B has a plurality of conductive connection pieces 25. The plurality of second contact arms 22B1 and the plurality of conductive connection pieces 25 can be connected by a plurality of flexible conductive sheets 27. In one example, a partial section of one end of the plurality of flexible conductive sheets 27 can be fixed to each other and appropriately cooperate with methods such as cutting to form at least one conductive connection piece 25; in another example, the plurality of flexible conductive sheets 27 and the plurality of conductive connection pieces 25 can be independent components, and one end of the plurality of flexible conductive sheets 27 can be divided into a plurality of sections, and each section is fixed to a conductive connection piece 25 respectively. Among them, the sections of the plurality of flexible conductive sheets 27 included in the second conductive member 22B between the plurality of second contact arms 22B1 and the plurality of conductive connection pieces 25 are not fixed to each other to form a flexible part. The flexible part can be deformed, and the plurality of second contact arms 22B1 and the plurality of conductive connection pieces 25 can be displaced relative to each other through the flexible part.

[0073] The first contact arm 22A1 and the second contact arm 22B1 are arranged front and back. When the power connector 100A is plugged into the power supply component, the power supply component abuts against the first contact arm 22A1 and the second contact arm 22B1 of each terminal group 2. A part of the conductive connection pieces 25 of the first conductive member 22A and the second conductive member 22B is arranged in the first accommodation space 181 and the second accommodation space 182 and is assisted and fixed by the fixing structure 18, and the other part extends out of the first accommodation space 181 and the second accommodation space 182 for electrically connecting the cable arranged in the accommodation space 13.

[0074] One end of one elastic member 24 of each terminal group 2 is fixedly arranged in a first card slot 183 of the insulating body 1A, and the other end of the elastic member 24 is arranged outside the first contact arm 22A1; one end of another elastic member 24 is fixed to a second card slot 184 of the insulating body 1A, and the other end is arranged outside the second contact arm 22B1, that is, located between the first conductive member 22A and the second conductive member 22B.

[0075] When the power connector 100A is plugged into the power supply member, both the first contact arm 22A1 and the second contact arm 22B1 will be abutted by the power supply member A1. At the same time, the two elastic members 24 provided on one side of the first contact arm 22A1 and the second contact arm 22B1 will elastically deform to provide an elastic restoring force, so that the first contact arm 22A1 and the second contact arm 22B1 firmly clamp the power supply member A1. In practical applications, one side of the first contact arm 22A1 adjacent to the free end may have a protrusion 22A11, and one side of the second contact arm 22B1 adjacent to the free end may have a protrusion 22B11. When the power connector 100A is plugged into the power supply member, the protrusion 22A11 and the protrusion 22B11 abut the power supply member, so that the first contact arm 22A1 and the second contact arm 22B1 firmly clamp the power supply member.

[0076] Please refer to Figures 17 to 19 , Figure 17 which is a schematic diagram of the third embodiment of the power connector of the present invention, Figure 18 and is a partial exploded schematic diagram of this embodiment, Figure 19 and is a schematic diagram of a part of the terminal group and the insulating base of this embodiment.

[0077] One difference between this embodiment and the second embodiment is that: the power connector 100B further includes a locking member 28. The insulating body 1A and the insulating cover 1B may respectively have a first locking port 1A1 and a second locking port 1B2, and the locking member 28 can pass through the first locking port 1A1 of the first insulating body 1A and the second locking port 1B2 of the insulating cover 1B to lock the two to each other, thereby strengthening the connection strength between the insulating body 1A and the insulating cover 1B. The locking member 28 may include a body 281 and an elastic structure 282; when the body 281 is fixedly disposed in the first locking port 1A1 and the second locking port 1B2, the elastic structure 282 may deform and be locked in the first locking port 1A1 to ensure that the locking member 28 is positioned in the first locking port 1A1 and the second locking port 1B2. The user can cancel the locking by pressing the elastic structure 282 to remove the locking member 28.

[0078] As Figure 19 shown, another difference between this embodiment and the aforementioned second embodiment is that: each terminal group 2 does not include the second conductive member 22B (as Figure 12 shown). Each terminal group 2 further includes two elastic members 24. One end of each elastic member 24 is fixed to the insulating base 1, and the other end of each elastic member 24 is disposed on one side of each first conductive member 22A. One end of each elastic member 24 may be separated to form two sheets 241 or a plurality of elastic arms, and the two sheets 241 (or the plurality of elastic arms) may be respectively disposed on one side of the first contact arm 22A1.

[0079] As Figure 19 shown, another difference between this embodiment and the aforementioned second embodiment is that the other end of the first conductive member 22A can be connected to two conductive connection pieces 25. In other words, the two conductive connection pieces 25 located in the same accommodation space 13 are connected to the same first conductive member 22A.

[0080] As described above, through the design of multiple elastic members 24 cooperating with multiple conductive members, the power connector 100A of this embodiment can not only transfer a large current, but also ensure that an appropriate clamping force is maintained between the power connector 100A and the power supply member A1.

[0081] The above are only the preferred and feasible embodiments of the present invention, and do not limit the patent scope of the present invention. Therefore, all equivalent technical changes made by using the content of the specification and drawings of the present invention are included in the protection scope of the present invention.
