## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This application is a continuation application of U.S. Ser. No. 15/733,913, filed on Dec. 1, 2020, which is a US national phase application based upon an International Application No. PCT/CN2020/122556, filed on Oct. 21 2020, which claims the priority of Chinese Patent Application No. 202021356336.9, entitled “REPLACEABLE SOCKET DEVICE”, filed on Jul. 10, 2020, the disclosure of which is incorporated herein by reference in its entirety.


FIELD OF THE INVENTION
This disclosure relates to a replaceable socket device, and more particularly to a replaceable socket device widely utilized in various types of jacks.
BACKGROUND
The sockets for domestic and commercial electricity are generally categorized into types utilized in 100-120V or 200-240V. The 100V-120V socket is further divided into a two-hole type and a three-hole type. Therefore, the type of the sockets has to be chosen in advance before installing or purchasing sockets. For example, the three-hole type sockets utilized to 200-240V should be installed nearby where the air-conditioner will be set, and the two-hope type or the three-hole type sockets utilized in 100-120V should be installed nearby where the electronic appliances will be set. In addition, not only should the voltage should be considered, the types of sockets should be noted as well in case, for example, the three-pin plug will not fit the two-hole sockets. Furthermore, the plugs have to be inserted in specific direction, in this situation, the power cable will be curved and the insulation layer of the power cable may rupture, resulting in leakage of electricity or a short circuit.
The electronic appliances which are purchased overseas cannot be used anymore since the sockets do not fit the plugs. Although there are adapters available on the markets, however, it's inconvenient to attach an adapter on the plug, and occupy more space and sometimes cause danger due to the low-quality of the adapters.
Furthermore, the Power Line Communication (PLC) technologies allow the network data to be transmitted by the power cables. The PLC technologies requires modems installed on sockets or network bridge with PLC functions, however it's inconvenient to attach an adapter on the plug, and occupy more space as well.

Please refer to FIG. 7 and FIG. 8, which are exploded views of the replaceable socket device in FIG. 1 and FIG. 2. There is a jack 22 disposed on a top of the adapter 20 and contacts 24 disposed on a bottom of the adapter 20. The base 30 includes one or more sockets 34.
Please refer to FIG. 8, FIG. 9 and FIG. 13. FIG. 9 illustrates an enlarged view of the contacts 24 and the sockets 34. There is a jack 22 disposed on a top of the adapter 20 and contacts 24 disposed on a bottom of the adapter 20. There is an adapting interface 40 disposed on the socket 34. Each socket 34 includes a bottom surface 341 and a sidewall 342 perpendicularly connected to the bottom surface 341 to form an opening 343. One of the plurality of adapters 20 inserts in the socket 34 via the opening 343.
Please refer to FIG. 10, which shows the structure of the contact 24 after turning the adapters 20 over. The structures of the adapting interface 40 correspond to the contacts 24. The details of the contacts 24 and the adapting interface 40 are as shown in FIG. 11. Please refer to FIG. 11, there are POGO PINs 400A-400P disposed on the adapting interface 40, and there are flat connectors 240A-240P, which correspond to the POGO PINs 400A-400P, disposed on the contacts 24. The POGO PIN 400A connects to the flat connector 240A. The POGO PIN 400B connects to the flat connector 240B. The POGO PIN 400P connects to the flat connector 240P. The structures of the contacts 24 and the adapting interface 40 when they are connecting to each other are shown in FIG. 12. The POGO PINs 400A-400P connect to the flat connectors 240A-240P to make the power be transmitted from the base 30 to the jack 22.
Please refer to FIG. 13, which illustrates the cross-section view of the POGO PINs 400A-400P and the flat connectors 240A-240P when they are connected to each other. The adapter 20 couples to the socket 34 via the contacts 24 and the adapting interface 40 so that the power can be transmitted from the base 30 to the jack 22. In the preferable embodiment, the top of the POGO PIN 400A-400B is lower than the bottom surface 341 of the socket 34. Accordingly, user's finger will not directly touch the adapting interface 40 to prevent from electric shock when the adapter 20 assembled on the socket 34.
In addition, there is still a first magnetic part 26 located on the adapter 20, and a second magnetic part 46 located on the adapting interface 40 where the first magnetic part 26 magnetically connects to the second magnetic part 46. The first magnetic part 26 and the second magnetic part 46 can connect to each other at any time, or connect to each other only if there is power existing. For example, first magnetic part 26 located on the adapter 20 could be an electromagnet. When the adapter 20 is set on the socket 34, the first magnetic part 26 connects to the external power via base 30 so the first magnetic part 26 possess magnetism that allows the first magnetic part 26 to magnetically connect to the second magnetic part 46. In another embodiment, the first magnetic part 26 is an electromagnet which does not possess magnetism since the power has not been conducted when the adapter 20 is set on the socket 34. After the plug of an electronic device is inserted into the jack 22, the power will be supplied to the electronic device and the first magnetic part 26 to make the first magnetic part 26 possess magnetism so that the first magnetic part 26 can magnetically connect to the second magnetic part 46. The adapter 20 could be fixed securely on the socket 34 through the connection between the first magnetic part 26 and the second magnetic part 46, thus that replaceable socket device will be safer. The first magnetic part 26 being an electromagnet is just one of the embodiments. The second magnetic part 46 can be an electromagnet as well. Moreover, the present disclosure does not limit to use electromagnets to get the magnetic connection. Any materials which can make the first magnetic part 26 and the second magnetic part 46 magnetically connect to each other fall into the scope of the present disclosure.
The potential of each contacting point of the contacts 24 and the adapting interface 40 are different, which may divide into the live lines, neutral lines or earth lines (ground lines). The contacting point of the contact 24 and the adapting interface 40 could be divided into several groups according to the types of the jack 22. For example, the adapting interface 40 can be grouped into the first potential and the second potential which may correspond to live lines and neutral lines. For another example, the adapting interface 40 can be grouped into the first potential, the second potential, and the third potential which may represent to the live lines, neutral lines, and earth (ground) lines. The structures of the adapter 20 of present disclosure could be designed to be non-directional. The flat connectors corresponding to the POGO PINS mentioned in FIG. 9-FIG. 13 could be grouped into two groups, live lines and neutral lines, according to the potential. As shown in FIG. 14, take flat connectors 240A-240P as example, the contacting point of the flat connectors and the POGO PINS could be divided into X group and Y group. And the arrangement of the group makes the contacting points stay in the same order no matter how the adapter 20 turns.
The 16 contacting points can further divide into three groups of live lines, neutral lines, or earth (ground) lines. As shown in FIG. 15, the 16 contacting points are divided into three groups: X, Y, and Z. The arrangement make the order of the 16 contacting points remain the same no matter how the adapter 20 turns. Therefore, the adapter 20 can be set on the socket 34 regardless the direction so that the adapter 20 could be turned into any direction as wished.
Please refer to FIG. 16 which shows the second embodiment. It is worth mentioning that the POGO PINs can not only be disposed on the adapting interface 40, but can also be disposed on the contacts 24.

In this embodiment, the contacts 24 include POGO PINs 241A-241P, and the adapting interface 40 includes the flat connectors 401A-401P. The POGO PIN 241A connects to the flat connector 401A. The POGO PIN 241B connects to the flat connector 401B. The POGO PIN 241P connects to the flat connector 401P. The cross-section view of the POGO PINs and the flat connectors after they connect to each other can take FIG. 13 as reference. The only difference between the second embodiment and the first embodiment is that the flat connectors are located on the socket 34 and the POGO PINs are located on the adapter 20. Furthermore, in the preferred embodiment, the top of the POGO PINs located on the adapting interface 40 are lower than the bottom surface 341 of the socket 34 when the flat connectors located on the adapter 20. Accordingly, user's finger will not directly touch the adapting interface 40 to prevent from electric shock when the adapter 20 assembled on the socket 34.
Please refer to FIG. 17 which illustrates the third embodiment. The contacts 24 and the adapting interface 40 have 9 contacting points. The contacts 24 include POGO PINs 242A-242I. The adapting interface 40 includes flat connectors 402A-402I which correspond to the POGO PINs 242A-242I, respectively. The cross-section view of the POGO PINs and the flat connectors after they connect to each other can take FIG. 18 as reference. The only difference between the third embodiment and FIG. 18 is that the flat connectors 402A-402I are located on the socket 34 and the POGO PINs 242A-242I are located on the adapter 20. FIG. 18 illustrates the cross-section view of the POGO PINs 242A-242I and the flat connectors 402A-402I after they connect to each other. The adapter 20 couples to the socket 34 through the contacts 24 and the adapting interface 40 so that the power can be transmitted from base 30 to jack 22
In the fourth embodiment, the POGO PIN can be located on the adapting interface 40 and the flat connectors corresponding to the POGO PINs can be located on adapter 20. The cross-section view of the forth embodiment can take FIG. 13 as pnreference.

Accordingly, user's finger will not directly touch the adapting interface 40 to prevent from electric shock when the adapter 20 assembled on the socket 34.
The contacting points of the third embodiment and the fourth embodiment can be grouped as the first and the second embodiment. Please refer to FIG. 19, take the flat connectors 402A-402I as example, the flat connectors can be divide into X group and Y group so that the arrangement of X and Y will remain the same no matter how the adapting interface 40 turns. Or refer to FIG. 20, the contacting points of the contacts 24 and the adapting interface 40 could be divided into three groups which represent live lines, neutral lines, and earth (ground) lines. The arrangement as shown in FIG. 20 makes the order of the X, Y, and Z remain the same so that the adapter 20 can fit the adapting interface 40 no matter how the adapting interface turns.
The contacts 24 and the adapting interface 40 of the replaceable socket device 10 can also be any type of contact and connector other than POGO PINs and flat connectors, like U-type contacts, square contacts, or circular contacts (not shown), cylindrical connectors, square-column connectors, rectangular-column connectors, circular connectors, or square connectors. The details will be illustrated in following paragraph.
FIG. 21 illustrates the structure of the U-type contact including contact clip 62 and fixing part 64. The contact clip 62 is usually made from metal for coupling to the connectors which have two contact points 622 and 624 with the contact clip 62. The fixing part 64 is utilized to fix the U-type contacts on the adapters 20 or the sockets 34. Please continue to FIG. 22.
FIG. 22 illustrates the fifth embodiment. In the fifth embodiment, the contacts 24 consist of 9 U-type contacts 243A-2431. The adapting interface 40 includes 9 cylindrical connectors which correspond to the U-type contacts 243A-2431. In this embodiment, take the U-type contact 243C and the cylindrical connector 403C as an example, the U-type contact 243C and the cylindrical connector 403C have two contact points 622C and 624C. The distance between the contact points 622C and 624C is narrower than the dimension of the cylindrical connector 403C. In addition, the contact clips of the U-type contact 243C are flexible so that they can stably couple to the cylindrical connector 403C.
As in the aforesaid embodiments that includes the POGO PINs and the flat connectors, the positions of the U-type contacts and the cylindrical connectors which are located on the contacts 24 and the adapting interface 40 respectively in the fifth embodiment can be switched.

In this embodiment, there are two contacting points between the U-type contacts and the contact clip. Take the U-type contact 244C and the square-column connector 404C as an example, the distance between the contact point 622C and 624C are narrower than dimension of the square-column 403C. Therefore, the U-type contact 244C can couple to the square-column connector 404C stably since the U-type contact 244C is flexible.
The adapting interface 40 of the eighth embodiment includes U-type contacts, and the contacts 24 are square-column connectors corresponding to the U-type contacts. The structures and the shape of the U-type contacts and the square-column connectors can take the seventh embodiment as a reference.
The contacts and the connectors of the fifth, sixth, seven, and eighth embodiments can also have 16 contacting points. The contacting points, no matter if there are 9 or 19 contacting points, can be divided into two or three groups by their potential as shown in FIGS. 14, 15, 19 and 20.
The openings of the U-type contacts are toward the same direction, however, the openings could be arranged toward different directions in order to make the adapters 20 more stable while installed on the sockets 34. The ninth embodiment illustrates an example that the U-type contacts are toward different directions as shown in FIG. 25. In FIG. 25, the contacts consist of 9 U-type contacts 245A-245I which are arranged in three lines. The first line is consisted of 245A-245C, the second line is consisted of 245D-245F, and the third line is consisted of 245G-245I. The U-type contacts 245D-245F in second line are toward to the same direction. The U-type connector 245A of the first line turns right at 45 degrees relative to the U-type connector 245D. The U-type connector 245B turns right at 45 degrees relative to the U-type connector 245A. (That is, turns right at 90 degrees relative to the 245E.) The U-type connector 245C turns right at 45 degrees relative to the U-type connector 245B. (That is, turns right at 135 degrees relative to the 245F.) The U-type connector 245G of the third line turns left at 45 degrees relative to the U-type connector 245D. The U-type connector 245H turns left at 45 degrees relative to the U-type connector 245G. (That is, turns left at 90 degrees relative to the 245E.) The U-type connector 245I turns left at 45 degrees relative to the U-type connector 245H. (That is, turns left at 135 degrees relative to the 245F.)
Please refer to FIG. 25 and FIG. 26. The adapting interface 40 includes 9 rectangular-column connectors 405A-405I corresponding to the U-type contacts 245A-245I in the ninth embodiment. The rectangular-column connectors are arranged in three lines as well. The rectangular-column connectors 405A-405C form the first line. The rectangular-column connectors 405D-405F form the second line. The rectangular-column connectors 405G-405I form the third line. The rectangular-column connectors 405D and 405F are arranged in the same direction.
The rectangular-column connector 405E is a square-column connector in this embodiment to make the adapting interface 40 symmetric to both centerline and diagonal so that the sockets 34 and the adapters 20 are non-directional in the present disclosure. However, please refer to FIG. 26, any shapes which make the sockets 34 non-directional can be utilized in the rectangular-column connector 405E of the present disclosure, being a square-column is just one of the examples. The directions of the rectangular-column connectors 405A-405C arranged in the first line are required to correspond to the U-type contacts 245A-245C, therefore, the rectangular-column connector 405A turns left at 45 degrees relatively to the rectangular-column connectors 405D. The rectangular-column connectors 405B turns left at 45 degrees relative to the rectangular-column connectors 405A. (That is, turns left at 90 degrees relative to 405D.) The rectangular-column connectors 405C turns left at 45 degrees relative to the rectangular-column connectors 405B. (That is, turns left at 135 degrees relative to 405D.) Similarly, the directions of the rectangular-column connectors 405G-405I arranged in the third line are required to correspond to the U-type contacts 245G-245I, therefore, the rectangular-column connector 405G turns right at 45 degrees relative to the rectangular-column connectors 405D. The rectangular-column connectors 405H turns right at 45 degrees relative to the rectangular-column connectors 405G. (That is, turns right at 90 degrees relative to 405D.) The rectangular-column connectors 405I turns right at 45 degrees relative to the rectangular-column connectors 405H. (That is, turns right at 135 degrees relative to 405D.)
Please refer to FIG. 27 which illustrates the structure of the U-type contacts 245A-245I and the rectangular-column connectors 405A-405I after they are connected. Connecting the U-type contact 245A to the rectangular-column connector 405A, the U-type contact 245B to the rectangular-column connector 405B, the U-type contact 245C to the rectangular-column connector 405C in FIG. 25 can get the structures illustrated in the FIG. 27. Similar connections are made between the U-type contacts 245D-245I and the rectangular-column connectors 405D-405I respectively and will not be mentioned herein. The U-type contacts 245A-245I couple to the rectangular-column connectors 405A-405I. Take the U-type contact 245I and the rectangular-column connector 405I as an example, there are two contact points 622I and 624I between the U-type contact 245I and the rectangular-column connector 405I. The distance between 622I and 624I is narrower than dimension of the rectangular-column connector 405I. In the meanwhile, the U-type contact 245I is flexible, so that the contacts 24 will be stably connected to the adapting interface 40. In addition, since the directions of the U-type contacts are different, the adapter 20 will fasten onto the socket 34.
Please refer to FIG. 28. In the tenth embodiment, the contacts 24 consist of square contacts 246, and the adapting interface 40 includes the square connectors 406 corresponding to the square contacts 246.
