CROSS-REFERENCES TO RELATED APPLICATION
[0002] This application also incorporates by reference the
US Patent 7,717,717 "User-Friendly USB Connector" in its entirety. Joseph Lai is the sole inventor of
the
US patent 7,717,717 and the invention is disclosed in this application.
FIELD OF THE INVENTION
[0003] This present invention will improve the existing conventional difficult-to-use electrical
connectors such as USB type A, micro USB, USB type C and many other computer and smart
phone connectors. It also improves non-electrical connectors which are not designed
for user-friendly quick and easy connection and disconnection. It adds magnet force
to assist the mating for the existing male and female connectors.
BACKGROUND OF THE INVENTION
[0004] Why is this invention necessary?
[0005] We all know the electronics devices with magnetic force assisted connectors are very
cool to have. How about the rest of million other devices are not built-in with the
magnetic force assisted connectors?
[0006] -The problems:
- 1. Small connectors, such as the micro USB for phones, get damaged very easily and
quickly as they are not user-friendly and not reversible. Often the connectors are
made too flimsy and if too much force is applied it will end-up damaging the connectors.
- 2. It is too expensive or not possible to convert existing non-reversible connectors
to be reliably reversible. Some newly developed computer connectors are extremely
difficult to re-engineer to make them reversible. USB 3.0/3.1 and micro USB connectors
are examples. They cannot be made user-friendly to be reversible and reliable.
- 3. Small reversible connectors such as iPhone's Lightning connectors are too small,
too expensive to handle and too easy to break. Again, making small connectors reversible
is not an easy task.
- 4. Furthermore, reversibility is nice, but for those who are vision impaired or have
other handicaps, they need something better to help them, it should be something better
than reversible for user-friendly.
- 5. We need more durable connectors because we are connecting and disconnecting them
all the time.
- 6. There are safety issues. Some equipment is too dangerous for normal connectors
to tightly attach. The home hot water boiler is one example: The power supply cord
attached to the boiler may be accidentally tripped over and not be able to release.
That could cause serious injuries. Magnetic force assisted connector adapters can
be useful to prevent mishaps from happening, since magnetic forces are weaker than
the current connections which always tightly hold by frictions and simply do not easily
separate from the cord.
- 7. There are EMI and RFI problems for certain high-speed leaky transmission lines
and connectors. USB3.0 is an example.
- 8. Yes, wireless chargers are user-friendly but they are too expensive, too slow,
too bulky, and waste too much energy.
- 9. Many other non-electrical connectors never have any improvements made to be user-friendly.
- 10. Planned obsolescence: New connectors need new cables with new mating connectors.
When new phones come out, the old cables and connectors are not compatible anymore.
Imagine if you have whole bunch old cables with old connectors, what will you do?
[0007] -The solution:
Our present invention modifies male or female connectors by adding a magnet, using
low-cost magnetic forces to help guide, attract, and attach the connectors. This allows
a clean signal and makes connections at either normal or reversed positions when the
magnets are engaged for both electrical and non-electrical applications.
SUMMARY OF THE INVENTION
[0008] Using magnets to help make connections is not new. Apple, Microsoft and many others
have their computers, phones, tablets, and smart watches using magnets to assist their
connections. However, existing non-magnetic assisted connectors may be modified to
have such capability for user-friendliness.
[0009] The present invention relates to a magnetic force assisted connector adapter as claimed
in claim 1 and to a method of magnetic force assisted connector adapter as claimed
in claim 11.
[0010] The following description and the appended dependent claims relate to different aspects
and embodiments of the present invention.

DETAILED DESCRIPTION
[0012] Smartphones, computers and all modem electronic devices have at least one thing in
common; they are all required to be plugged in for either power or other type of applications.
Normally, these devices are not designed to be user-friendly in their original design.
Therefore, user-friendly modifications can be very important for many of the users
who use these devices all the time.
[0013] Of course, not all devices must be user-friendly but it sure is nice to have that
feature available which will not cost much more. Some peripheral devices, such as
printers and keyboards, mice for desktop computers, only have to plug in the power
and the cable one time. It does not have to be detached.
[0014] However, most of other devices such as laptop computers, cellular phones or other
portable electronic devices running on portable power (battery) do require charging
the battery regularly. It is absolutely necessary for a user-friendly way of using
these devices.
[0015] Today's smartphone for example, is designed as a pocket computer and communication
device. Power consumption is very high. Charging is required at least once a day by
going through AC adapters or battery power banks. The connector on the phone is constantly
plugged and un-plugged all the time. This can test both the patience of the user and
the durability of the connector. Typical connectors on the phones made by Apple are
already converted to be reversible. The vast majority of the other non-Apple phones
are still using the non-reversible micro USB connectors. Micro USB connectors are
too small and are not the best connectors for being installed on the phones. However,
EU has already mandated that micro USB is the standard for all cellular phones. It
is extremely difficult to make the small micro USB to be reversible and user-friendly.
Making the micro USB to be reversible is going to be very expensive and extremely
unreliable or just not possible. This presented invention uses magnetic force as the
alternative solution for making all non user-friendly connectors become user-friendly
for electrical and non-electrical connectors with magnetic force assisted connector
adapters.
[0016] Fig. 1. Shows prior art of possibly the first user-friendly magnetic assisted connection
by Japanese Panasonic and others as they adopted the technologies since early 1990's.
105 is a portable hot water boiler with 103 nozzle to dispense hot water to 104 tea
cup. 101 is the male connector for AC power with magnetic force to connect to 102
as the AC power receptacle. 106 is the AC power cord attached to the 101. Please notice
the original design has safety in mind as the magnetic force holding the 101 to 102
is relatively weaker force than a normal power cord plugged into to a hot water boiler.
The water boiler is designed to be portable with a handle 107. When someone accidently
trips over the power cord 106, it will automatically detach instead of dragging the
hot water boiler and spilling it all over.
[0017] Fig. 2. Also shows the prior art of other consumer electronics use magnetic force
to assist connect power to their devices. Fig. 2A shows Apple's Macbook laptop computer
has built-in magnetic force connectors 202 on the cable end 106 with 201 is the power
receptacle. Apple called it "MagSafe" as the plug and receptacle will be separated
when someone accidentally trips over or drags the 106 instead of the whole computer
being dragged and dropped down to the floor and getting damaged. Please also notice
the MagSafe was designed to be "reversible" for user-friendly sake.
[0018] Fig. 2B. Shows the Microsoft's tablet PC as the brand of "Surface". It has the same
design with magnetic force to help the user to plug-in the power with its reversibility.
Fig. 2C is a Smart Watch made by Pebble also with magnets as the assisting force when
the watch need to be charged. 208 is the contacting circuits on the watch to mate
207 have "pogo" or spring loaded pins. With the magnetic force, when 207 has 2 magnets
near 208, 207 will attract 208 and snap onto the surface with the contacting points
to make connections for delivering the power to charge the Pebble watch. The Pebble
watch connector, however, is not designed to be reversible.
[0019] Fig. 3. Shows a typical prior art of a pair of male and female electrical connectors.
Fig. 3A with 301 is the female receptacle or socket to allow the 302 male plugs to
be inserted in it for making the connection. 106 is the cable attached for delivering
either power or signal to the female 301. Fig. 3B shows when these two connectors
301 302 mate and make the connection. Many different electrical connectors, such as
Lighting, USB, HDMI, RJ-45, and Thunderbolt are designed to mate like this.
[0020] Fig. 4. Shows the magnetic force assisted adapter by this present invention. For
all the above mentioned and not mentioned connectors, they are either non-user-friendly,
non-reversible, or non-magnetic force assisted. We can make an adapter to make it
reversible and be magnetic force assisted to create user-friendly connection applications.
[0021] Fig. 4A. Shows the 302 conventional male connector is split into two parts, 401 and
402 sub-assemblies. 401 and 402 are also holders which hold the magnet, contact surface
and contacting circuits or channels. On 402, we have 2 magnets 405 and some spring
loaded pogo pins 404. On 401, we also have either 2 magnets 406 or magnetic attractable
surface with some flat contact points 403. We also have 407 which is the conventional
male plug which has the same male plug as 302 does.
[0022] Fig. 4B. Shows the 401 sub-assembly plugs into the 301 female receptacle with 406
and 403 exposed to the outside. Fig. 4C. Shows the magnetic force attraction of the
402 sub-assembly by the 405 magnets to 406 flat magnetic attractable surface when
they are getting closer.
[0023] Fig. 4D. Shows the 401 and 402 sub-assemblies are connected now. The 405 and 406
physically touch and the pogo pins 404 pushed in and retracted because of 403 surface
forced by the magnetic force. The adapter is now making connections.
[0024] Please note both 405 the magnets and 406 the magnetic attractable piece/surface do
not necessarily have to be just a single round/square individual magnet or magnets.
It can also be a donut shaped, or oval shaped with a hole or holes to let the pogo
pins go through for a tight mate from the 405 surface with the magnet or 406 just
a magnetic attractable piece. For strengthening the magnetic force if we have to,
406 can also be real magnets with the matching polarity of the N and S of the magnets.
[0025] Fig. 5. Shows the non-electrical type of magnetic force assisted connection applications.
The non-electrical connections can be fiber-optical signals/data, or solid, liquid
or gas types of materials. For example, Fig. 5A shows the 405 and 406 are magnets
or magnetic attractable surfaces which are installed on 502 and 501 assemblies. 504,
505, 506 are carrying channels. 507 is the supplying channel for many different type
of materials, for example, water hose or compressed air hose. Fig. 5B shows half of
the adapter is plugged into the regular 501 female receptacle and leaves the magnetic
attractable surface and the channel exposed outside. Fig. 5C. Shows these two parts
of the adapter getting closer. Fig. 5D. Shows the connection is made with the magnetic
force.
[0026] Of course, when connecting non-electrical air, gas or liquid stuffs, additional leakage
prevention apparatus are necessary to prevent leak.
[0027] Fig. 6 shows a typical smartphone has the charging and communication port at the
bottom of the phone. Fig. 6A shows the 401. The part will go inside and stays inside
the phone of the adapter. For 402 as the other half of the adapter which connects
to the power supply cables. Fig. 6B shows the 401 already plug in and stays inside
of the phone. 402 is ready to be attracted to mate with the 401 which is exposed outside
of the phone.
[0028] Fig. 7. Shows the locking and unlocking mechanism of the magnetic force assisted
connector adapter. Fig. 7A shows the locking part does not exist and the 401 can be
held by friction when inserted into the female micro USB connector of the phone as
Fig. 7B. Fig. 7C shows the locking hook 701 is installed on the 401 so at 7D when
inserted into 301 female micro USB, it will be lock in to prevent un-intentionally
release when someone pulls the 402 apart of the adapter. It is suggested to use an
un-locking mechanism such as a push rod level inside 401 to lower the spring loaded
hook 701 so it can be released when necessary.
[0029] Another suggestion is to use an L shape of a piece as 7E. For a typical Smartphone,
the L shape 703 extending to the back side of the phone so many ways can be done to
hold the L shaped piece that holds the 401 when inserted into the 301 without un-intentionally
releasing the 401 assembly. Double sided adhesive tape is one example.
[0030] Also, if the smartphone, tablets or other devices, has a protection case, it is recommend
to use the case to help hold/lock the assembly of the adapter which plugs into the
devices. Fig 7G is showing the front view of the adapter without the supporting plate
that holds the 401 and Fig 7H shows the 401 part of the adapter is supported by a
supporting plate of metal or plastic 705 which is located in between the phone and
the protection case when the 401 is completely inserted into the female receptacle
of the phone or other devices. No special instruction is required when user disconnect
their 402 part of the adapters. The adapter 401 for sure it won't fall off. For removing
or releasing the 401, the user has to remove the protection case first. Of course,
when designing a new protection case, with or without battery, 401 can be considered
to build into the protection case. 401 will never fall off unintentionally.
[0031] The other way to prevent the un-intentional release of 401 is to bend the 402 assembly
to disconnect the 402 from 401. Strong magnet is used for this application and the
weak part of the 401 402 bond is to bend and break apart if L shaped 703, 705 piece
for protection case or locking hook 701 are not implementable.
[0032] Fig. 8. Shows the reversibility of the magnetic force assisted connector adapter.
Fig. 8A. Shows the detailed 5 pin micro USB is off centered to the left side of the
402 with 5 pogo pins 404. Fig. 8C also shows the detailed 5 pin micro USB is off centered
to the right side of the 402. Fig. 8B has the 401 assembly surfaced with a PCB which
has 5 rings of circuitry to connect to the 404 pogo pins in either normal or reversed
positions.
[0033] Fig. 9. Shows the reversibility of magnetic force assisted connector adapter using
bridge rectifier diodes for reversed and normal connections. Bridge rectifier diodes
can be smaller in size compared to a PC board but it has the voltage drop of typical
diodes. Schottky diode has low drop voltages around 0.2V which are more appropriate
for this application to only deliver power to the device.
[0034] It worth mentioning that magnets are capable of inducing electrical currents, and
therefore could reduce EMI or RFI for high-speed data transmission. Normally, engineers
are using ferrite beads to wrap around high-speed transmission wires/cables to reduce
the noise for FCC and other agencies for their compliance tests. In this invention,
a magnet will help to reduce these annoying RFI and EMI noise without the expense
of the ferrite core/bead.
[0035] Another feature that is necessary to have is the circuitry for supplying the power
must have protection circuitry in case of short circuits as the strong magnets might
attract conductive metal, which could cause problems. Over current protection is one
electrical way, and a recessed surface on 402 is another mechanical method. In other
words, if the magnet attracts to a flat conductive metal, the pogo pin will not touch
the surface of that metal.
Conclusion:
[0036] Magnetic force may not be something we understood but we can use this amazing material
and making our life easier. Magnetic force assisted connector is a great way to connect.
For those devices do not have this feature, a magnetic force assisted connector adapter
is the best solution for converting non-magnetic, non-reversible, non-user-friendly
connectors to being user-friendly.
Warning:
[0037]
Magnets may be dangerous at stronger strengths. When working with strong magnets,
be careful to protect your body parts not to be exposed to both sides of attracting
magnets.
Strong magnets can be very dangerous for causing injuries to humans and animals when
attracted either to another magnet or magnetic attractable metal surfaces.
