TECHNICAL FIELD
[0001] The present invention relates to an electronic block, and more particularly to a
modular block and an electronic block system applied to teaching of experiments and
electronic block toys.
BACKGROUND
[0002] It is known that a traditional electronic block system for teaching of experiments
or electronic block toys usually includes a complete circuit board and various functional
devices. Designated lines and installation holes are provided on the circuit board.
In use, the required functional devices are installed on the circuit board to achieve
specific functions. However, a common circuit board or functional device is an undetachable
integrity. Such a product is limited to a few single functions and thus has poor flexibility.
For a user who likes to manually detach or splice a toy, he/she cannot learn the structures
and functions of various functional modules in this product and thus it is of a low
interesting.
[0003] Chinese patent
CN203108212U discloses a magnetically attractive electronic block system, which includes a plurality
of connected electronic block modules. Each electronic block module includes a circuit
board, a plug connector and a socket connector. The circuit board is provided with
three groups of signal lines, i.e., a positive power line, a data signal line and
a negative power line. The plug connector and the socket connector include an insulating
body and three conductive terminals. The insulating body is provided with a plurality
of accommodating grooves where a permanent magnet is installed. The three conductive
terminals are respectively connected to corresponding signal lines on the circuit
board. One of the plurality of electronic block modules includes a power and signal
generation module for providing a power source and a signal source. The other plurality
of electronic block modules cascade with the power and signal generation module successively.
[0004] However, this disclosed technique has the following problems during practical application.
- 1. It is limited to three groups of lines on the circuit board and the connector,
which limits the expansive usage of the data signal lines and also the development
of more functions of the electronic block system.
- 2. Arrangement of the magnet has an applicability problem. First, the multi-magnet
design has high requirements on the placement of the pole thereof, which is not beneficial
for the reduction of manufacture costs; it directly occupies a large portion of the
coupling surface of the insulating body and thus is not beneficial for the expansion
of more conductive connectors. It is more important that the magnet is directly exposed
on the coupling surface, which hampers the protection to the magnet. The magnet will
be easily oxidized after long-time hand contact and collision and will produce magnet
power debris due to the exposure. In the meantime, the magnet will gradually lose
efficacy and the magnet attraction force will be reduced due to magnet debris, and
even the magnet will be damaged.
- 3. It limits that the placement of the conductive connectors has to be "arranged on
the insulating body side by side". This limitation can achieve relevant functions
but its "side by side arrangement" will cause high requirements on space and thus
the expansion of more conductive connectors is restricted seriously. It is also not
easy to be processed during manufacturing and the costs are high.
SUMMARY
[0005] An object of the present invention is to provide a modular block and an electronic
block system to solve one or more of the above problems.
[0006] In order to achieve the above object, according to an aspect of the present invention,
a modular block is provided which comprises a circuit board, a functional circuit
disposed on the circuit board, an input connector and an output connector. The input
connector and the output connector are both provided with a plurality of conductive
terminals connected to the circuit board. The plurality of conductive terminals are
a positive power conductive terminal, a negative power conductive terminal and a data
signal conductive terminal respectively. At least one of the input connector and the
output connector is provided with a plurality of the data signal conductive terminals.
In this way, on the modular block, a data signal may be input via one wire and output
via a plurality of wires and it may also be input via a plurality of wires and output
via one wire. On the modular block, a data signal may also be input via a plurality
of wires and output via a plurality of wires. The input connector and the output connector
of the modular block can be provided with one or more data signal conductive terminals
according to actual needs. Thus, data signal lines can be expanded for use and the
modular block will have more functions and applications.
[0007] In some embodiments, the conductive terminals are probes and conductive elements
matching the probes. One of the probes and the conductive elements is provided at
the input connector and the other is provided at the output connector. In this way,
a plurality of modular blocks may achieve conductive connections through the matching
of the probes and the conductive elements.
[0008] In some embodiments, the input connector and the output connector both include a
main body and a rear cover which are both made of an insulating material. The rear
cover is detachably mounted on the main body. The main body or the rear cover has
a cavity and an attraction element is provided in the cavity. In this way, the attraction
elements of the main body and the rear cover are provided inside the input connector
or the output connector, which protects the attraction elements and prolongs the service
life of the attraction elements. The attraction element can be a magnet or a magnetically
attractive metal.
[0009] In some embodiments, the cavity is provided in the middle of the main body or the
rear cover. A plurality of the conductive terminals are arranged at the outer circumference
of the cavity in a way of not side by side. In this way, the input connector or the
output connector is merely provided with one magnet or one magnetically attractive
metal. Thus, the placement requirements on the magnet's pole are lowered and the space
is saved. The plurality of conductive terminals are provided in a stagger way, which
lowers the requirements to the space.
[0010] In some embodiments, the modular block further includes a fool-proofing bump and
a fool-proofing notch. One of the fool-proofing bump and the fool-proofing notch is
provided at the connector and the other is provided at the output connector and the
shape and size of the fool-proofing bump and the fool-proofing notch are mating with
each other. In this way, the provision of the fool-proofing structure ensures a precise
and stable coupling of the input connectors and the output connectors of two modular
blocks.
[0011] Accordingly, the present invention also provides an electronic block system including
the above modular block. This electronic block system further includes a power and
signal generation module block cascading with the modular block. The functional circuit
of the modular block includes a function execution device. The power and signal generation
module block is provided with a power circuit and a signal source circuit. The power
circuit and the signal source circuit are electrically connected to the input connector
of the modular block. In this way, the electronic block system facilitates expansive
use of data signal lines and the development of more functions.
[0012] In some embodiments, there are a plurality of modular blocks and the functional circuit
of at least one of the plurality of modular blocks includes a relay connection unit.
In this way, the connection of modular blocks has a changeover function, which can
achieve the splicing of a plurality of modular blocks.
[0013] The beneficial effects of the present invention are as follows.
- 1. The modular block in the present invention is provided with one or more data signal
conductive terminals, which expands usage of data signal lines and improves the development
of more functions of the electronic block system.
- 2. The input connector or the output connector of the modular block is provided with
one magnet or a magnetically attractive metal, which greatly lowers the placement
requirements to the pole of the magnets to facilitate the reduction of manufacture
costs. It will not occupy the coupling surface of the insulating main body, which
facilitates the expansion of more conductive terminals and protects the magnet well.
Moreover, such placement of the conductive terminals may also make full use of the
space and facilitate the expansion of more conductive terminals.

and an output connector 4 are connected to the circuit board 1. The input connector
3 and the output connector 4 are both provided with a plurality of conductive terminals
5 connected to the circuit board 1. The plurality of conductive terminals 5 are a

element 34 is a magnet or a magnetically attractive metal.
[0018] It should be noted that the attraction elements 34 of the input connector 3 and the
output connector 4 may all be magnets or the attraction element 34 of one of the two
connectors is a magnetically attractive metal. If the attraction element 34 of one
of the input connector 3 and the output connector 4 is a magnetically attractive metal,
the attraction element 34 of the other connector is a magnet. In this way, the input
connector 3 and the output connector 4 can achieve coupling to each other.
[0019] There is one cavity 33 and it is provided in the middle of the main body 31 or the
rear cover 32. The plurality of conductive terminals 5 are arranged at the outer circumference
of the cavity 33 in a way of not side by side but around the cavity 33. In this embodiment,
the cavity 33 is provided in the middle of the main body 31.
[0020] The modular block further includes a fool-proofing bump 35 and a fool-proofing notch
