Description

[Detailed Description of the Invention] The present invention relates to an assembly type electronic block, and in particular, it is constructed by engaging and connecting a plurality of blocks each having an engaging groove and an engaging protrusion that serve as electrical connections on the outer peripheral surface. The present invention relates to a multidirectional assembly type electronic block that can be assembled into any electrical circuit or electronic application device.

Various insert-type or engagement-type electronic kits have been proposed in the past in order to eliminate the troublesome soldering work required for configuring electric circuits for electronics beginners and students in electronic experiments. Most configurations require the use of a power distribution board with multiple block insertion holes on the top surface, so when constructing an electric circuit or electronic application device, the size, shape, and arrangement of the insertion holes of the board must be carefully considered. etc., it is only possible to obtain an electric circuit device arranged in a two-dimensional manner on a board, and it is impossible to obtain a circuit device arranged in three-dimensional arrangement.In addition, when configuring the same electric circuit, it is difficult for anyone to construct the same electric circuit. The disadvantages were that only certain layouts, shapes and configurations could be obtained, there was little variety, and the user got tired of it.

Furthermore, electronic blocks have been proposed in which an electric circuit is constructed simply by fitting and connecting blocks without using a board, but such blocks cannot change direction at the fitting and connecting parts, In the configuration of such an electric circuit, it can only be assembled into a uniform shape and arrangement as described above, and there is little variability.

The present invention was devised in order to eliminate the drawbacks of the conventional electronic blocks as described above, and in an electronic block that does not use a board, one of the connected blocks is configured to be rotatable relative to the other at an engaging connection part. The present invention provides a multi-directional assembly type electronic block with the following characteristics.

The present invention will be described below with reference to embodiments shown in the drawings.

As shown in FIGS. 1 and 2, the electronic block B of the present invention is formed mainly of a hollow square molded from synthetic resin, and its six outer peripheral surfaces are arranged in three pairs, including two opposite surfaces. divided into planes of
Vertical engagement grooves 11, 11 are provided in the center of each of the first pair of surfaces 1, 1 therein;
The width of the opening of this engagement groove 11 is narrower than that of the bottom. Further, a head is provided at the center of the second pair of surfaces 2, 2, respectively, into the engaging groove 1.
Flat circular engaging protrusions 21, 21 formed in a shape that can be freely engaged with the blocks 1, 11 are fixedly protruding from the block B, and the third pair of surfaces 3, 3 are formed flat. There is.

As shown in FIGS. 3 and 4, the third pair of surfaces 3,
One of the blocks 3 is provided with an opening that communicates with the hollow part 4 of the block B, and a lid 31 having guide edges 32 on both sides of the opening connects the guide edges to the opening. By fitting into the guide grooves 33 formed on both sides, one end of the hollow part 4 is closed, and the other end (bottom surface shown) is formed into a flat surface integrally molded with the block B, and the other end of the hollow part 4 is sealed. are doing. Elongated slits 12 and 22 are provided at the bottom of the engagement groove 11 and the head of the engagement protrusion 21, respectively, and U-shaped conductive contact pieces 5 and 6 are inserted into these slits 12 and 22, respectively. The legs 51, 61 of the contact pieces 5, 6 are bent and fixed by pressing against the inner wall of the block (see FIG. 4).
In addition, in the hollow part 4 of block B, electronic components E,
For example, resistors, transistors, capacitors, diodes, and the like are housed, and both ends thereof are connected via lead wires 7 to connection holes 52, 62 provided in the legs 51, 61 of the contact pieces 5, 6. A lead wire 7 is also connected between the contact pieces 5 and 6. The connection relationship between the electronic member E and the contact pieces 5 and ₆ by the lead wire 7 is not the same as that shown in _FIG . It is clear that the connection can be made as follows.

FIG. 5 shows a state in which two or more blocks are connected, and the engaging protrusion 21 of another block B ₂ is engaged in the engaging groove 11 of block B ₁ . The above-mentioned blocks B ₁ and B ₂ are connected so that the contact piece 5 of the engagement protrusion 21 and the contact piece 6 of the engagement protrusion 21 are in close pressure contact, and the electronic member E between them is electrically connected due to this connection relationship. keeping. To maintain the connection of the electronic member E, first insert the contact pieces 5, 6 into the slits 12, 22, insert the electronic member E,
After passing both ends of the lead wire 7 at the output end through the holes 52 and 62 of the legs 51 and 61 of the contact pieces 5 and 6,
This can be achieved by bending the blocks 1 and 61 so as to bring them into close contact with the inner circumferential wall of the block B (the dotted line in FIG. 4 shows the state before bending). After the connection, the electronic component E is pushed into the block so that it is completely housed in the hollow part 4, and then the hollow part 4 is closed by fitting the lid body 31 into the guide edge 32 and the guide groove 33. A complete block B as shown in FIG. 1 is constructed.

As shown in FIG. 5, the blocks _B1 and _B2 , which are electrically connected to each other by the engagement protrusion 21 and the engagement groove 11, are aligned on one side on the axis A with the engagement protrusion 21 as the center. Since one can freely rotate 360 degrees in the direction of arrow D or D' with respect to the other, the relative locking direction after connection can be adjusted and held in any direction. Through such a connection, another block (indicated by a chain line) can be engaged with the other engagement groove 11 or engagement protrusion 21, and blocks can be added one after another to create an electronic application having a desired circuit and shape. A circuit can be constructed.

Figures 6 and 7 show other embodiments of blocks, in which block _B3 is a rectangular block with twice the volume of block B, and block _B4 has a volume four times that of block B. In this case, one or two contact pieces 5 and engaging protrusions 21 or 6 are provided on the same side so as to be combined in correspondence with the block B. It is being The block _B3 thus formed corresponds to a combination of two blocks B, and the block _B4
corresponds to a combination of four blocks B. In this case, the hollow portion of block _B3 or _B4 also increases in proportion, and can accommodate large-volume electronic components such as transformers, coils, capacitors, batteries, etc.

FIG. 8 shows another embodiment of the block B of the present invention. The basic structure of this block B is the same as that of the previous embodiment, but only the way in which the contact pieces 5 and 6 are attached is different. That is, the contact piece 5 is previously formed in a V-shape, and is inserted from above so as to sandwich the bottom surface of the engagement groove 11 of the block B and the inner wall surface of the hollow portion 4, and is fixed thereto. An elastic protrusion 53 is formed in a portion of the contact piece 5 located within the hollow portion 4, and is pressed out to facilitate attachment of the contact piece 5 and the electronic component E. Further, it is preferable that the contact piece 5 is provided over the entire length of the engagement groove 11. Note that the contact piece 6 is a vertically long groove 2 provided in the other inner circumferential wall facing the hollow part 4.
3, and the inner end of a conductive engagement protrusion 21 is caulked to the contact piece 6 at the center thereof.
The contact piece 6 is provided with an elastic protrusion 63 which is pressed out in the same way as the contact piece 5.
In this embodiment, since the guide groove 33 is not provided in the opening of the block, the lid is adhered to the opening with adhesive to close the opening.

Of course, the mounting method and shape of the contact pieces 5 and 6 can be modified in various ways in addition to the configuration of the above embodiment. Further, on the bottom surface or the lid of the block, there are printed symbols indicating the electronic components installed in the block and circuits indicating their input and output terminals. Therefore, it is very convenient to distinguish parts and misidentify circuits during assembly.

FIG. 9 shows an example of assembling an electric circuit using the blocks of the present invention. As can be seen from this usage example, the user can assemble a plurality of blocks B, B ₃ ,
By using _B4 and engaging the engagement protrusion and the engagement groove, it is possible to easily assemble it from a plane to a three-dimensional structure to form a desired circuit.

Since the present invention is constructed as described above, there is no need for a board during assembly, and it can be assembled into any three-dimensional shape like conventional building blocks.゜Since it is rotatable, it is possible to obtain assembled finished products with different shapes even when configuring the same electrical circuit, which is highly variable, and is limited by the size of the board and type of kit in conventional products. It is an extremely practical product, as it allows you to assemble a wide variety of electronic application devices or equipment by adding and assembling blocks as you wish.
