The present invention relates generally to an electrical connector and connector elements thereof for a modular construction element and/or system.
Many different types of electrical connectors exist today.
Certain types of connectors are based on the well-known RJ12 (registered jack) connector having a male plug and a female jack that especially is used for connecting telecommunications or data equipment but also have found use in other equipment.
The plug and jack of a RJ12 connector (and many more RJ connectors) snap or click together using a locking element requiring a press on a fairly small surface before they safely can be separated again. This way of separation is and not very suitable for certain types of users, e.g. (young) children; especially if a small form factor of the connector also is preferred.
If the RJ12 or a similar connector is used to connect to a device, it is fairly easy to break the connector, or rather the locking element of it, e.g. if a person inadvertently trips in or otherwise gets caught by the wire of the connector. This is especially the case if the device is used on the floor, which quite often can be the case for certain devices like toys, etc. Furthermore, the device itself may also get pulled (both if the connector breaks and not) risking breaking or damaging the device as well.
Often standard RJ12 and similar connectors are equipped with fairly rigid wires, which do not make them particular useful for certain connections

Needing to unlock the connectors before separation is possible is not very intuitive. Especially for certain types of users such as children or young children.
Additionally, many types of existing connectors are not suitable for use and/or integration with one or more modular construction elements and/or a system of such.
There is therefore a need for a connector and connector elements that alleviate one or more of the above mentioned drawback at least to some extent; especially for users such as (young) children.
According to a first aspect, disclosed herein is a first electrical connector element for a modular construction element and/or system, the first electrical connector element comprising
Accordingly, an electrical connector element is provided facilitating simple and reliable connection and disconnection, even by users such as children and even after repeated use (connection/disconnection). A user may simply pull the first and second electrical connector elements apart by applying a resulting force in an un-mating direction (being parallel and opposite to a mating direction) being larger than the predetermined release threshold.
By being subjected to pull forces or one or more pull forces is to be understood as being subjected to a resulting pull force (e.g. comprising a plurality of pull force components) generally in the un-mating direction.
In some embodiments, the number of lock and release elements is/are adapted to release the coupling between the first and the second electrical connector elements when the plurality of electrical conductors, e.g. in the form of a wire, cable, etc., is subjected to one or more pull forces above the predetermined release threshold.
In this way, a user may simply pull the electrical conductors (or wire, cable, etc. comprising the electrical conductors) with a sufficient resulting force in the un-mating direction being larger than the predetermined release threshold.
In some embodiments, the predetermined release threshold is a member selected from the group consisting of: 5 or more Newton, 7.5 or more Newton, 10 or more Newton, or 15 or more Newton. The actual predetermined threshold may vary according to specific embodiment.

In some embodiments, the strain relief part is adapted to bend the plurality of electrical conductors at least once, e.g. twice (e.g. as shown in
In some embodiments, the strain relief part is adapted to bend the plurality of electrical conductors an even number of times.
In some embodiments, a housing of the first electrical connector element comprises a recess where the plurality of electrical conductors exits the housing, the recess allowing the plurality of electrical conductors to bend, outside the housing, away from or across a mating direction (or correspondingly the parallel opposite un-mating direction) without extending further than a length of the housing in the mating direction.
This is especially advantageous when using such a first electrical connector element together with one or more modular construction elements and/or a system of such since the plurality of electrical conductors then easily may bend ‘out of the way’, especially if the plurality of electrical conductors is flexible, so as to no interfere or obstruct with otherwise adjacent modular construction elements (e.g. as illustrated in
In some embodiments, the plurality of electrical conductors exits the first electrical connector element in a direction being substantially parallel to an un-mating direction. This facilitates reliable and intuitive un-mating or un-coupling of the first and second electrical connector elements from each other by a user pulling the plurality of electrical conductors (or wire, cable, etc. comprising the electrical conductors).
In some embodiments, the plurality of electrical conductors is formed at least in part as a flexible and/or flat cable.
In some embodiments, the plurality of electrical conductors has a maximum width being at most about 8 millimetres.

The shown figures are schematic representations for which reason the configuration of the different structures as well as their relative dimensions are intended to serve illustrative purposes only.
Some of the different components are only disclosed in relation to a single embodiment of the invention, but is meant to be included in the other embodiments without further explanation.
Shown is one embodiment of a first electrical connector element 100 and a second electrical connector element 200 where the first electrical connector element 100 is adapted, during use, to be mechanically, electrically, and releasably connected and coupled with the second electrical connector element 200 thus forming one embodiment of an electrical connector 100; 200. The first electrical connector element 100 is coupled to the second electrical connector element 200 by (relatively) moving the first electrical connector element 100 along a mating direction and they are separated again by (relatively) moving the first electrical connector element 100 along an un-mating direction (being parallel and opposite to the mating direction). It is to be understood, that the first electrical connector element 100 may be held still while moving the second electrical connector element 200 (then in the direction called un-mating direction above; thus the use of relatively moving.
The electrical connector and its first and second connector elements are preferably for use in or with a modular construction element and/or system as will be explained further e.g. in connection with
In the shown and similar embodiments, the first electrical connector element 100 is a male plug connector while the second electrical connector element 200 is a female jack connector. As alternatives for all embodiments throughout the description, the first electrical connector element 100 and the second electrical connector element 200 may be a female jack connector and a male plug connector, or a male jack connector and a female plug connector, or a female plug connector and a male jack connector, respectively.
The first electrical connector element 100 comprises a first or main connector part 101 comprising a plurality of electrical contacts (not shown; see e.g. 106 in
Embodiments of how the electrical contacts and the electrical conductors may be connected and arranged are shown and explained further e.g. in
In some embodiments, the number of connectors and number of conductors are six and/or the conductors form a flexible flat cable. Alternatively, the conductors may be arranged as another type of cable but that will typically not be as flexible.
In addition, the first electrical connector element 100 further comprises a strain relief part 103. The strain relief part 103 is adapted to—when assembled with the first connector part 101 e.g. using ultrasonic welding—hold and bend the electrical conductors 105 securely (please see e.g.
The function of the strain relief part is further explained in the following and also illustrated and explained in connection e.g. with
Instead of being assembled together, the strain relief part 103 and the first connector part 101 e.g. be formed by a single piece or element as an alternative.
Furthermore, the first electrical connector element 100 comprises a number of (in this particular and similar embodiments two) resilient lock and release elements 110 or the like. It is to be understood, that in other embodiments, the lock and release elements does not need to be resilient (e.g. as shown in
The resilient lock and release elements 110 are adapted to engage with the second electrical connector element 200 when the first and the second electrical connector elements 100; 200 are mechanically connected thereby mechanically coupling the first and the second electrical connector elements 100; 200 together and forming an electrical connection between them with their respective electrical contacts 106; 106′ as will be explained further in the following.
In this particular and similar embodiments (e.g. like the ones shown in connection with
This provides a very easy and intuitive way for a given user of separating the first and second electrical connector elements 100; 200 from each other again, in particular by pulling the electrical conductors 105. Especially so, if the user is a child or a relatively young child and the connector elements are used in modular construction elements and/or systems (not shown; see e.g. 300 in
The lock and release function provided by the resilient lock and release elements 110 function especially advantageously together with the strain relief part 103 since the strain relief part 103 secures and bends the electrical conductors 105 thereby strengthening the connection between the electrical conductors 105 and the first electrical connector element 100 significantly enabling it to be able to withstand pull forces from a given user (both children and adults) even after repeated use.
Basically, when the electrical connectors 105 are pulled by a user, whereby a resulting force being larger than a predetermined release threshold of the resilient lock and release elements 110, the resilient lock and release elements 110 will release (the first connector element 100 from the second 200) before the strain relief part 103 releases the electrical connectors 105 from the first connector element 100 by a very large margin, i.e. the release threshold of the resilient lock and release elements 110 are lower (even significantly so) than a release threshold, as mainly provided by the strain relief part 103, between the electrical connectors 105 and the first connector element 100.
When a user is pulling sufficiently, a resulting force in an un-mating direction (where the un-mating direction is generally parallel and opposite to a mating direction) is applied that is larger than the predetermined release threshold of the resilient lock and release elements 110 thereby separating the first and second electrical connector elements 100; 200 from each other.
By being subjected to pull forces or one or more pull forces is to be understood as a resulting pull force (e.g. comprising a plurality of pull force components) being applied generally in the un-mating direction.
In some embodiments, the predetermined release threshold of the resilient lock and release elements is a member selected from the group consisting of: 5 or more Newton, 7.5 or more Newton, 10 or more Newton, and 15 or more Newton. The actual predetermined threshold may vary according to specific embodiment.
In some embodiments, the predetermined release threshold of the resilient lock and release elements is a value selected from the interval of about 5 to about 15 Newton (e.g. the interval of 5 to 15 Newton).
In some embodiments, the release threshold of (mainly) the strain relief part is 100 Newton or more.
This easy, reliable, and intuitive way of separating the first and the second connector elements are especially advantageous for modular construction elements/system as an inherent aspect of these are that the modular construction elements are to be put together and separated again many many times.
In some embodiments, the first and/or second electrical connector element 100; 200 is/are adapted to release from each other when being subjected to one or more pull forces being 15 or more Newton and adapted to not release from each other when being subjected to one or more pull forces being 5 or less Newton.
In some embodiments, the plurality of electrical conductors exits the first electrical connector element in a direction being substantially parallel to an un-mating direction. This facilitates reliable and intuitive un-mating or un-coupling of the first and second electrical connector elements from each other by a user pulling the plurality of electrical conductors (or wire, cable, etc. comprising the electrical conductors) since the resulting pulling force, by pulling the electrical conductors, generally will be coinciding with the un-mating direction.
As mentioned,
The second electrical connector element 200 in the shown exemplary embodiment further comprises at least one securing or mounting element 120 for securing or mounting the second electrical connector element 200 to something else. Examples of this are explained further in connection with
In embodiments, where the first electrical connector element 100 is a male plug connector and the second electrical connector element 200 is a female jack connector, the second electrical connector element 200 also comprises an opening 102 receiving a protruding part of the first electrical connector element 100.
Inside this opening 102, the second electrical connector element 200 comprises a number of recesses, grooves, slits or the like 107′ where each grooves, slit, etc. comprises one electrical contact 106′ (explained further in relation to
Correspondingly, the protruding part of the first electrical connector element 100 comprises a number of recesses, grooves, slits or the like (not shown; see e.g. 107 in
When the first and second electrical connector elements are being coupled together, the protruding part will be inserted into the opening 102 and at least a part of the electrical contacts (not shown; see e.g. 106 in
The opening 102 in this and similar embodiments also has space to receive the resilient lock and release elements 110 of the first electrical connector element 100 when this is inserted into the second electrical connector element 200.
In embodiments like the ones shown in
In the embodiments of
Such resilient lock and release elements 110 may e.g. be snap pegs, springs or other resilient protrusions, etc. Alternatively, other resilient or non-resilient snap locks could be used (e.g. as shown in
Such snap fit connections furthermore provide a tactile connection confirmation upon use to the user.
The length of the resilient lock and release elements 110 may be substantially the same as the length of the rest of the protruding part (comprising the recesses, openings, etc. 107 and contacts 106), the lengths being measured from the strain relief part 103.
There is in these embodiments also a gap between the resilient lock and release elements 110 and the rest of the protruding part to allow for a spring effect of these elements 110.
It is to be noted, that the resilient lock and release element(s) 110 as an alternative could also be located in the second electrical connector element 200 with the receiving opening(s) 112 being located in the first electrical connector element 100, even a mix thereof with some resilient lock and release element(s) 110 and receiving opening(s) in one of the first and second electrical connector elements and a corresponding number of opposite elements and openings in the other of the first and second electrical connector elements.

The first electrical connector element 100 comprises a strain relief part 103 and a first or main connector part 101 (on the hidden side; see e.g.
The first electrical connector element 100 comprises a number of (in this example two) lock and release elements 110 adapted to engage with the second electrical connector element 200 when they are coupled together.
The lock and release elements 110 each comprises an engaging portion 111 for engaging with the second electrical connector element as explained already.
A difference to the first electrical connector elements e.g. shown in
Another difference is the shape of the first electrical connector element 100 at its surface where the plurality of electrical conductors 105 exits the housing of the first electrical connector element. See e.g. the encircled areas 500 in
Additionally, the housing of the first electrical connector element still has a portion 501 that is at least substantially flat.
These features make it advantageous to use the first electrical connector element 100 with modular construction elements and/or systems of such modular construction elements as e.g. may be seen from
This allows for the use of modular construction elements and systems where a presence of electrical connector element(s) 100 will restrict the building possibilities, creativity, etc. the least.

As can be seen, the first or main connector part 101 and the strain relief part 103 of this embodiment are different from the embodiments e.g. shown in
More specifically, the electrical conductors 105 are bent in a u-shape and effectively bent four times while the electrical conductors 105 in the embodiments of
In some embodiments, the strain relief part 103 is adapted to bend the plurality of electrical conductors 105 an even number of times. This allows that the general length-wise direction of the electrical conductors generally is parallel with the un-mating direction.
Shown in
As can be seen, one of the electrical contacts 130 is offset compared to the other electrical contacts 106 in the direction of insertion into a second electrical connector element. Preferably, the offset electrical contact 130 is the electrical contact having, in use, an electrical ground potential (GND). In this particular embodiment and similar, the offset electrical contact 130 is the third electrical conductor or pin but could of course be a different one with other signal layouts.
The offset electrical contact 130 effectively ensures that this is reliably the first connector to make electrical contact.

The M0 signal is a first device control signal, e.g. a first actuator, motor, sound generator, and/or light control signal or the like, provided, during use, at a first electrical conductor or pin; the M1 signal is a second device control signal, e.g. a second actuator, motor, sound generator, and/or light control signal or the like, provided, during use, at a second electrical conductor or pin; the GND signal is an electrical ground potential provided, during use, at a third electrical conductor or pin, and the NC signals are so-called ‘Normally Closed’ signals provided, during use, at third to sixth electrical conductors or pins, respectively.
In use, the M0 and/or the M1 signal may be used to provide basic control of a connected relatively low power electrical device, e.g. like a low power actuator like a mini, a small, or a medium sized motor, one or more light elements, one or more sound generators, etc. The M0 signal may e.g. be used to supply power and drive a connected electrical device, i.e. effectively being an on/off signal for that electrical device while supplying the necessary power to activate and run it. More specifically, M0 may be used to provide (e.g. unregulated) power with a relatively high output current to an electrical device e.g. as usable by a motor or other. The provided power may be continuous power or pulse width modulation (PWM) power and may e.g. be supplied in the range from about 5V to about 9V while output current may e.g. be supplied in the range from about 0.5 A to about 1.2 A depending on the connected electrical device.
Only second electrical connector elements located in an electrical device with its own power supply can provide power e.g. via the M0 signal.
In use, the M1 signal may be used to provide another control signal to the connected electrical device. This may e.g. for an actuator or a motor be a rotation or drive direction. The M1 signal may also be used to provide power as explained for the M0 signal as an alternative or an addition to the M0 signal.
The GND signal is for supplying an electrical ground potential while the NC signals are not used for the simple output port.
Thus an output port or unit is provided that readily and simply can control a connected active electrical device (e.g. as shown in
Illustrated in
M0, M1, and GND correspond to the M0, M1, and GND signals as described earlier (and may be provided, during use, at the same respective electrical conductors or pins) while the PWR signal is a power signal, provided, during use, at a fourth electrical conductor or pin, for supplying additional power, which may be needed or be advantageous for connected electrical components or systems requiring (additional) external power and/or power supplied in another form than as supplied by M0 and/or M1.
Furthermore, the DIG0 and DIG1 signals provide digital In/Out and/or digital communication at a given speed, e.g. from about 2.4 to about 115 kbaud e.g. depending on the requirements of the connected electrical device.
The DIG0 and DIG1 signals are provided, during use, at a fifth and sixth electrical conductor or pin, respectively. The DIG0 signal may be a transmission/Out signal and the DIG1 signal may be a reception/In signal. The DIG0/DIG1 signals may both be a UART (Universal Asynchronous Receiver/Transmitter) signal and/or digital I/O signals.
The PWR signal may supply regulated power at about 3.3V being limited to about 35 mA.
This provides—compared to the output port of

Thus an input port or unit is provided that readily and simply can receive input or information from a connected electrical device, which then may be processed and/or communicated to other units.
Illustrated in
M0, M1, GND, PWR, DIG0, and DIG1 correspond to the corresponding signals as described earlier.
In this way, an input/output port or unit is provided that readily and simply provides a combination of the capabilities of the input port and the output ports (both the simple and the advanced).
The port configurations of
Furthermore, when the electrical layout of the electrical conductors/pins for the various types of ports are configured as described, the different ports is supported fully by a second electrical connector element and a corresponding first electrical connector element having only 6 electrical conductors/pins.
Additionally, the signal layout on the respective pins is compatible in the sense that a given pin signal is the same across all the different port configurations (or not used). E.g. first pin is M0 (or not used e.g. as for the input port), second pin is M1 (or not used for e.g. as for the input port), third pin is GND, etc. for all the different explained port configurations.
For these various port configurations it may for certain embodiments and uses be an advantage that the (output, input, input/output) port can identify what specific type of (connected) electrical device is actually connected to the given port. This may be realised in different ways.
According to an aspect, using one, more or all of the above mentioned port configurations, identification of a connected electrical device may be provided using the DIG0 and/or DIG1 signal where an appropriate identifier or the like may be transmitted via digital communication by the connected electrical device to the respective port it is connected to upon connection and/or according to another scheme, e.g. like upon request. This does not provide identification of a connected electrical device for the simple output port.
As an alternative or in addition, identification of a connected electrical device may be provided by supplying a predetermined combination of signals to a given set electrical conductors or pins of the port, preferably at the electrical conductors or pins providing the DIG0 and DIG1 signals, e.g. at the fifth and sixth electrical conductors or pins, respectively. This enables identification of a connected electrical device for the simple output port as well and also another way of identification for the other ports. Such identification also allows for identification of connected electrical devices that does not necessarily comprise a microcontroller or similar.
According to this, receiving a GND signal at the fifth and a PWR signal at the sixth electrical conductors or pins may identify the connected electrical device as being of a first predetermined type, as an example being a low power actuator (such as a mini or small sized motor).
Receiving a PWR signal at the fifth and a PWR signal at the sixth electrical conductor or pin may identify the connected electrical device as being of a second predetermined type, as an example being a medium motor.
Receiving a PWR signal at the fifth and a GND signal at the sixth electrical conductor or pin may identify the connected electrical device as being of a third predetermined type, as an example being a train motor.
Receiving a GND signal at the fifth and a GND signal at the sixth electrical conductor or pin may identify the connected electrical device as being of a fourth predetermined type, as an example being a high power actuator (such as a large motor, extra-large motor, or a polarity switch).
Shorting or short-circuiting the fifth and the sixth electrical conductors or pins and connecting them to GND using an appropriately valued resistor, i.e. an identification resistor, may identify the connected electrical device as being of a fifth predetermined type, as an example being a simple touch sensor, button, activation switch, and/or the like. Using differently valued resistors may identify the connected electrical device as being of another predetermined type according to the value of the resistor.
Other predetermined signal combinations, e.g. the fifth electrical conductor or pin being an inversion of the sixth electrical conductor or pin or vice versa, may identify additional predetermined types.
Other or additional predetermined types may e.g. include a (simple) light element/emitter, a converter, sound generator, etc.
This provides a simple way of identification of a connected electrical device, simply by the connected electrical device applying the appropriate signal combinations at the appropriate pins whereby a connected electrical device then does not necessarily need to comprise a microcontroller or similar.
As mentioned above, this may be supplemented by identification using digital communication, i.e. to enable identification of additional (more than the five listed above) types of connected electrical devices.
Additionally, some connected electrical devices may also supply an identifier using a so-called ID resistor (i.e. a given resistor having a resistor value being unique for that type of electrical device), e.g. for analog sensors or the like.
It is to be understood that other signal types, signal combinations, and/or types of connected electrical devices in principle may be used according to given other embodiments and uses.
It is also to be understood that the ordering of which signals is expected at which electrical conductors or pins may be changed without a different effect, as long as it consistently is adhered to.

In this particular example, the connected electric device 710 is a simple relatively low power motor.
As can be seen, the connected electrical device 710 is configured, during use, to have an M0 signal (at a first electrical conductor or pin), an M1 signal (at a second electrical conductor or pin), three GND signals (at third, fifth, and sixth electrical conductors or pins, respectively), and one NC signal (at a fourth electrical conductor or pin).

M0, M1, GND, PWR and NC correspond to the corresponding signals as described earlier.

In this particular example, the connected electric device 710 is a relatively advanced motor like an advanced servo motor also receiving additional power via the PWR signal if needed.

M0, M1, GND, PWR, DIG0, and DIG1 correspond to the corresponding signals as described earlier.
Once more, the particular type of connected electric device 710 may be identified, as described earlier, by supplying appropriate identification DIG0 and/or DIG1 signals at two predetermined electrical conductors or pins, specifically shown as number 5 and 6, using digital communication. For connected electrical devices, e.g. comprising a micro controller, processor, and/or the like, that is controlled through digital communication it is an advantage to use digital communication for identification of the connected electrical device as well as it is readily available.

In this particular example, the connected electric device 710 is a sensor in the form of an analog touch-based switch.
Sensors are generally able to provide at least one sensor input and may preferably be identified (to an electrical device 700) as described earlier.
The particular type of connected electric device 710 may be identified, as described earlier, by supplying an appropriate signal (SW) at electrical conductors or pins 5 and 6.

It is to be understood that even if a given connected electric device 710 has been described to connect to a given port it may equally well be connected to another port providing or supporting the same functionality (plus perhaps additional functionality), e.g. instead of being connected to a simple output port it could be connected to an advanced output port or to an input/output port, instead of being connected to an input port it could be connected to an input/output port, etc.

The difference between the

As can be seen, a realisable size, as shown, of the first and second electrical connector elements 100, 200 are relatively small, even compared to an RJ12 or similar connector, making them very suitable for integration into certain existing lines of modular construction elements.
Such modular construction element 300 as shown may be used together with other modular construction elements (not necessarily comprising any connector elements although some may indeed do so) to form a modular construction system including electronic functions, etc.
Conductors in the form of a flexible (e.g. flat) cable may be advantageous, especially when used with at least two modular construction elements 300 comprising a second electrical connector element 200 and a flexible (e.g. flat) cable comprising a first electrical connector element 100 in each end, since the cable may connect the two modular construction elements 300 even if they are put on top of each other, next to each other, etc. due to the flexibility of the cable.
All or some of the modular construction elements 300 may comprise the port functionality as described in connection with
By having a modular construction system comprising a number of modular construction elements where at least one element comprises a port and/or an electrical device, a very versatile modular construction system is provided with electric functionality having a modular and a constructional aspect.
In embodiments, as shown e.g. in
Shown is a perspective view of one embodiment of a second electrical connector element 200 adapted to receive a first electrical connector element as shown in

Another difference is the shape or profile of the electrical contacts 106′ of the second electrical connector element 200. In the shown embodiment, the respective shapes are raised or bent ‘upwards’ at the ends closer to the first electrical connector element when received while in embodiments as shown e.g. in
