Abstract
Description
- This application claims the benefit of foreign priority to Japanese Patent Application No. 2018-178146, filed on Sep. 21, 2018, which is incorporated by reference in its entirety.
- The disclosure relates to an electronic circuit holder.
- Conventionally, in order to learn electronic circuits, commercially available electronic circuits or breadboards have been used (for example, see Japanese Patent Laid-Open No. 2014-212152). For example, a plurality of lines connected to each terminal of an electronic circuit are inserted into socket holes arranged in a matrix on a breadboard, and a plurality of electronic circuits are connected via the breadboard. As a result, an electronic device can be experimentally produced.
- However, when the lines extending from the electronic circuit are connected to the breadboard, the electronic circuit may be moved by pulling the lines, which makes a wiring operation difficult. Also, in a case where a first electronic circuit has already been connected to the breadboard, the lines of the first electronic circuit may be pulled out of the socket holes if the breadboard is moved when a second electronic circuit is further connected, which makes the wiring operation difficult.
- Further, when a plurality of electronic circuits are connected via the breadboard, wiring routing becomes complicated unless each electronic circuit is arranged at an appropriate position to the breadboard, for example.
- The present invention has been made in view of the foregoing, and an object of the present invention is to provide an electronic circuit holder which can execute simple wiring operation and can eliminate complication of the wiring routing from an electronic circuit.
- In some embodiments, an electronic circuit holder includes: a fixing plate, a pair of side wall plates between which the fixing plate is configured to be interposed, and a seat having a plurality of seat-side lock penetrating holes arranged at a predetermined interval. The fixing plate has a fixing portion for fixing an electronic circuit on a surface of the fixing plate, and lock protrusions on opposed sides of the fixing plate. A first of the pair of side wall plates has first lock penetrating holes, and a second of the pair of side wall plates has second lock penetrating holes. The lock protrusions of the fixing plate are engaged with the first and second lock penetrating holes to hold the fixing plate at a predetermined height. The first of the pair of side wall plates has, on a side thereof, a first wall-side lock protrusion, and the second of the pair of side wall plates has, on a side thereof, a second wall-side lock protrusion. The first and second wall-side lock protrusions are defined as a pair of wall-side lock protrusions configured to be engaged with a pair of seat-side lock penetrating holes of the plurality of seat-side lock penetrating holes. The seat allows a user to select the pair of seat-side lock penetrating holes from among the plurality of seat-side lock penetrating holes to engage the pair of wall-side lock protrusions with the pair of seat-side lock penetrating holes, thereby changing a position of the fixing plate on the seat in accordance with a position of another part to be installed on the seat. The first lock penetrating holes of the first of the pair of side wall plates and the second lock penetrating holes of the second of the pair of side wall plates are arranged in two or more rows. The position of the fixing plate is changed in a height direction of the seat by switching to one of the two or more rows of the first and second lock penetrating holes with which the lock protrusions of the fixing plate are engaged, in accordance with the position of another part to be installed on the seat.
- According to some embodiments of the present invention, the electronic circuit can be fixed to the seat together with other parts. Consequently, a wiring operation can be executed in a state that the electronic circuit is stabled, and thus the simple wiring operation can be executed. Also, the electronic circuit can be freely moved to a desired position on the seat and fixed to the seat in accordance with a wiring situation of the electronic circuit on the seat, which can eliminate complication of the wiring routing from the electronic circuit.
